After searching for a way to simulate the color changes found on lab grown bismuth crystals and dichroic glass, I eventually happened across Pruster's thin-film interference OSL shader. With the help of various literature and the OSL shader, I was able to adapt Pruster's script into a GPU compatible interference node group. Find Pruster's original news post here.
The interference group takes the complex refractive index of a substrate and up to two thin-film layers to calculate the physically-correct colors of the desired material. With it, materials such as aged copper, 'a thin-film on an arbitrary dielectric', car paint, and heated iron can be simulated correctly as seen below:
The interference group also has the option to simulate plain conductors such as gold and osmium:
And while we're at it, let's look at the golden reflections of a space helmet material and the shiny pastels of a dichroic glass material:
Only the interference node group is under the CC BY-NC-SA 4.0 license, but its output can be used for any purpose. All the materials shown here are only a small preview of what is provided in the blend file, so check it out and maybe even create your own materials with the interference node group.
Hope you enjoy it!


Vocal percussion
From Wikipedia, the free encyclopedia
Jump to navigation Jump to search
Vocal percussion is the art of creating sounds with one's mouth that approximate, imitate, or otherwise serve the same purpose as a percussion instrument, whether in a group of singers, an instrumental ensemble, or solo.
In Western music[edit]
Recent musicological research points at Brazilian songwriter and musician Marcos Valle as a pioneer of vocal percussion.[citation needed] In the track "Mentira" from his 1973 album "Previsao do Tempo", Valle imitates a drum kit with his voice.
Beatboxing, an artform pioneered by rapper Doug E. Fresh, is one school of vocal percussion, originating in hip-hop music and often used to accompany rapping. it is utilized by many musicians spanning over a wide variety of genres.
In Indian music[edit]
Vocal percussion is also an integral part of many world music traditions, most notably in the traditions of North India (bols) and South India (solkattu). Syllables are used to learn percussion compositions, and each syllable signifies what stroke or combination of strokes the percussionist must use.
The art of speaking these syllables is called konnakol in South India, and traditional dance ensembles sometimes have a dedicated konnakol singer, although this practice is now waning. At one time it was a very respected art form, with many masters and singers.
In North India, the practice of reciting bols is usually limited to the percussionist reciting the composition about to be played, often in the context of a longer solo. These recitations are also sometimes spoken by a Kathak dancer.
Mouth drumming[edit]
Mouth drumming is a form of Beatboxing which involves vocally imitating the sound of a drum kit as precisely as possible in order to use the voice to serve the same function as a drummer in a musical setting. It is mostly used in a cappella music but has also been used in rock and jazz. Artists who specialize in this technique are simply referred to as vocal percussionists.[1]
Wes Carroll is credited as the term coiner and pioneering practitioner of this art.[2] Well known for his ability to realistically vocalize the sounds of a drum kit, and use them as the primary rhythm section in bands and a cappella groups, he inspired many vocalists and musicians to continue this artform after him. Jeff Thacher and Dave Baumgartner[3] are other well known pioneers.
In a cappella[edit]
Many a cappella groups use mouth drumming as a way of using the voice to provide a steady rhythm section for their music.
A cappella groups such as Five o-clock Shadow, The House Jacks, Rockapella, Overboard, SoVoSo, Transit and Naturally 7 are well known for further advancing the art and its popularity.
In rock and jazz music[edit]
Although it is not common, mouth drumming has also been used in traditional band settings. David Worm (who has also performed it for the a cappella group SoVoSo) has often incorporated the technique in his acoustic rock band "Glass house". Kaichiro Kitamura[4] is a Japanese vocal percussionist specializing in this art who has incorporated it in both a cappella and jazz groups. Otha Major is another vocal percussionist and beatboxer, who has often used the technique in rock performances as well as with the a cappella group Kickshaw.

Mkhomazi State Forest, KwaZulu Natal
Mkhomazi is situated in the southern section of the Ukhahlamba Drakensberg Park. The Mkhomazi section of the Ukhahlamba Drakensberg Park is one of the most isolated and least explored mountainous areas in KwaZulu Natal. The area is not attached to the main escarpment and comprises of a number of elevated ridges protruding towards the Natal Midlands. Mkhomazi is one of the few areas in the Drakensberg where one can hike for days without seeing another soul. The ideal destination for a wild demanding hike.
Mkhomazi is characterized by numerous high altitude wetlands, deep gorges and rolling prairie-like grasslands. It is home to a variety of wildlife and bird species. Black Wildebeest, Mountain Reedbuck, Grey Rhybuck and Eland are the more commonly seen mammals but Caracal, Serval, Porcupine and Otter are also found in the Area. Some of the more common bird species include Bokmakierie, Golden Breasted Bunting and Stone Chat. Lammergeier, Cape Vulture and Black Eagle are also present but sighted less often.

Search results for: pressure fluctuation.
1 Piezoelectric Power Output Predictions Using Single-Phase Flow to Power Flow Meters
This research involved the utilization of fluid flow energy to predict power output using Lead Zirconate Titanate (PZT) piezoelectric stacks. The aim of this work is to extract energy from a controlled level of pressure fluctuation in single-phase flow which forms a part of the energy harvesting technology that powers flow meters. A device- Perspex box was developed and fixed to 50.8 mm rig to induce pressure fluctuation in the flow. An experimental test was carried out using the single-phase water flow in the developed rig in order to measure the power output generation from the piezoelectric stacks. 16 sets of experimental tests were conducted to ensure the maximum output result. The acquired signal of the pressure fluctuation was used to simulate the expected electrical output from the piezoelectric material. The results showed a maximum output voltage of 12 V with an instantaneous output power of 1 µW generated, when the pressure amplitude is 2.6 kPa at a frequency of 2.4 Hz.Procedia APA BibTeX Chicago EndNote Harvard JSON MLA RIS XML ISO 690 PDF Downloads 70

WoW API < GetFrameCPUUsage
Returns the total time used by and number of calls of a frame's event handlers.
time, count = GetFrameCPUUsage(frame[, includeChildren])
Arguments Edit
(frame[, includeChildren])
Frame - Specifies the frame.
Boolean - If false, only event handlers of the specified frame are considered. If true or omitted, the values returned will include the handlers for all of the frame's children as well.
Returns Edit
time, count
Number - The total time used by the specified event handlers, in milliseconds.
Number - The total number of times the event handlers were called.
Details Edit
The values returned are just the sum of the values returned by GetFunctionCPUUsage(handler) for all current handlers. Which means that it's not per-frame values, but per-function values. The difference is that if for example an OnUpdate handler is used by two frames A and B, and, say, B:OnUpdate() is called, both A and B get blamed for it.
It also means that if a frame's handlers change, the CPU used by the previous handlers is ignored, because only the current handlers are considered.

François-André Danican Philidor
Portrait from L'analyze des échecs. London, second edition, 1777.
|Full name||François-André Danican Philidor|
|Born||September 7, 1726
|Died||August 31, 1795
François-André Danican Philidor (September 7, 1726 – August 31, 1795), often referred to as André Danican Philidor during his lifetime, was a French composer and chess player. He contributed to the early development of the opéra comique. He was also regarded as the best chess player of his age; his book Analyse du jeu des Échecs was considered a standard chess manual for at least a century, and a well-known chess opening and a checkmate method are both named after him.
Musical family
François-André Danican Philidor came from a well-known musical family, which included:
- Jean Danican Philidor (c. 1620–79), André Danican Philidor's grandfather, was a musician at the Grande Écurie (literally, the Great Stable; figuratively, the Military Band) in Paris. The original name of his family was Danican (D'Anican) and was of Scottish origin (Duncan). Philidor was a later addition to the family name. Jean Danican Philidor was given the nickname of Philidor by Louis XIII because his oboe playing reminded the king of an Italian virtuoso oboist coming from Siena named Filidori.
- Michel Danican (died c. 1659), André Danican Philidor's great-uncle, was a renowned oboist and, together with Jean Hotteterre, coinvented the oboe by modifying the shawm so that the bore was narrower and the reed near could be held near the end by the player's lips.
- André Danican Philidor (c. 1647–1730), François-André Danican Philidor's father, was also known as Philidor l'ainé (Philidor the Elder). He was an oboist and crumhorn player. He was a member of the Grande Écurie military band and later performed at the Court, at the Royal Chapel, in the employ of Louis XIV.
- Jacques Danican Philidor (1657–1708) was the younger brother of André Danican Philidor (Philidor the Elder) and, being a musician, too, was logically known as Philidor le cadet (Philidor the Younger).
- Pierre Danican Philidor (1681–1731), also a musician, was the son of Jacques Danican Philidor.
- Anne Danican Philidor (1681–1728) was François-André Danican Philidor's oldest brother. Anne Danican Philidor is best remembered today for having founded the Concert Spirituel, an important series of public concerts held in the palace of the Tuileries from 1725 to 1791.
François-André Danican Philidor was born to his father's second wife, Elizabeth Le Roy, whom he wed in 1719 when she was 19 years old and he 72. When François-André was born, his father was 79 years old; he died 4 years later and left his son fatherless.
Music career
Philidor joined the royal choir of Louis XV in 1732 at the age of six, and made his first attempt at the composition of a song at the age of 11. It was said that Louis XV wanted to listen to the choir almost every day, and the singers, while waiting for the king to arrive, played chess to relieve their boredom; this may have sparked Philidor's interest in chess.
From around 1740 he lived and worked in Paris as a performer, teacher and music copyist. He was the teacher of the Bohemian composer and pianist Ludwig Wenzel Lachnith. During this time he met Diderot, who calls him 'Philidor le subtil' in Le neveu de Rameau. He spent much of the period 1745–54 in London after a concert tour of the Netherlands collapsed, and moved in the same circles as Dr Johnson and Dr Burney. He returned to the French capital in 1754, although his music was found by some to be too Italianate (as a result of his travels). However he scored several triumphs at the fair theatres, starting with Blaise le savetier in 1759. His three most successful works were Le sorcier (1764), Tom Jones (after Henry Fielding, 1765), and Ernelinde (1767).
For a time Philidor was among the leading opera composers in France, and during his musical career produced over 20 opéras comiques and two tragédies-lyriques. He also wrote secular cantatas and motets.
Chess career
Philidor started playing regularly around 1740 at the chess Mecca of France, the Café de la Régence. It was also there that he famously played with a friend from 'New England', Mr. Benjamin Franklin. The best player in France at the time, Legall de Kermeur, taught him. At first, Legall could give Philidor rook odds, a handicap in which the stronger player starts without one of his rooks, but in only three years, Philidor was his equal, and then surpassed him. Philidor visited England in 1747 and decisively beat the Syrian Phillip Stamma in a match +8 =1 −1, despite the fact Philidor let Stamma have White in every game, and scored all draws as wins for Stamma. The same year, Philidor played many games with another strong player, Sir Abraham Janssen, who was then the best player in England, and with the exception of M. de Legalle, probably the best player Philidor ever encountered. He could win on an average one game in four off Philidor, at even terms; and Philidor himself declared that he could only give to Janssen the pawn for the move.
In 1754, Philidor returned to France, after nine years of absence spent mostly in Holland and England. He was now a much stronger player, having successfully played with opponents of the calibre of Philip Stamma and Abraham Janssen, but, as G. Allen reports in The life of Philidor, it was not until his match with de Legal in 1755 that he can be considered the strongest player in the world.
When Philidor left Paris, in 1745, although he had for some time been playing even games with M. de Legal... he had not ceased to recognize his old master as still his master and superior. But nine years of practice, with a great variety of players, had authorized him to look for neither superior nor equal; and when, in 1755, a match was arranged between the pupil and his master, who was still at the height of his strength, the result placed the crown firmly and indisputably upon the head of Philidor.
In 1771 and 1773 Philidor made brief stays in London to play at the Salopian coffee-house, Charing Cross and at the St James Chess Club. In 1774 the Parloe's chess club, on St James street, in London, was created and Philidor obtained a remuneration as a chess master every year, for a regular season from February to June. Philidor stayed faithful to this agreement until the end of his life and he was replaced by Verdoni only after his death. It is rightly in this place Philidor encountered Mr. George Atwood, famous mathematician and physician, lecturer at Cambridge University. In an article of J. J. O'Connor and E. F. Robertson, devoted to George Atwood, there is the following passage:
Atwood was a renowned amateur chess-player and among other opponents played games against the famous French player Philidor, who was regarded as the unofficial world champion.
H E Bird records:
Of the players who encountered Philidor, Sir Abraham Janssens, who died in 1775, seems to have been the best, Mr. George Atwood, a mathematician, one of Pitt's secretaries came next, he was of a class which we should call third or two grades of odds below Philidor, a high standard of excellence to which but few amateurs attain. One of most interesting features of Atwood as a chess player is that he recorded and preserved some of his games, an unusual practice at that time. These records have survived, among them the last games that Philidor played which were against Atwood at Parsloe's Club in London on 20 June 1795.
In England, Philidor astounded his peers by playing three blindfold chess games simultaneously in the chess club of St. James Street in London on 9 May 1783. Philidor let all three opponents play white, and gave up a pawn for the third player. Some affidavits were signed, because those persons who were involved doubted that future generations would believe that such a feat was possible. Today, three simultaneous blindfold games would be fairly unremarkable among many chess masters. Even when he was in his late years, when he was 67 years old (1793), he played and won two blindfold games simultaneously in London.
Philidor, both in England and France, was largely recognized in each of his fields and got a lot of admirers, protectors and also friends, like were the French philosophers Vol

AN EFFICIENT MULTIACCESS PROTOCOL FOR WIRELESS NETWORKS. Benjamin W. Wah and Xiao Su. Department of Electrical and Computer Engineering.
AN EFFICIENT MULTIACCESS PROTOCOL FOR WIRELESS NETWORKS Benjamin W. Wah and Xiao Su Department of Electrical and Computer Engineering and the Coordinated Science Laboratory University of Illinois at Urbana-Champaign Urbana, IL 61801, USA E-mail: wah, xiao-su  @manip.crhc.uiuc.edu URL: _URL_ ABSTRACT In this paper, we propose and evaluate an efficient multiaccess protocol for cell-based wireless networks. Our protocol addresses the problems in existing random-access protocols for wireless networks: long-term fairness as well as short-term fairness in accessing a shared channel and the detection of hidden and exposed collisions. Our proposed protocol is a limited contention protocol in which the set of contending mobiles are chosen based on a global common contention window maintained by every mobile station. The contention window is adjusted based on three possible channel states: no transmission, success, and collision. We assume that the channel state at the end of each contention slot is broadcast by a base station in a control channel. We show analytically that the time interval between two successive accesses to the channel by any station is geometrically distributed, and that each station has equal chance to access the channel in every contention period. This is significantly better than existing random-access protocols based on the binary exponential backoff algorithm, which results in large variances in inter-access delays. Our experimental results also show that the number of contention slots to resolve collisions is constant on the average, independent of the number of contending stations. 1. INTRODUCTION The design of an efficient and scalable medium access control (MAC) protocol is extremely important for wireless networks, where bandwidth is a precious and scarce resource. Existing work on wireless medium access control protocols can be classified into two categories: ordered-access and random-access. Ordered-access protocols, such as tokenbased and polling schemes, rely on knowledge of the network configuration in order to predetermine the use of a shared channel. They are usually very efficient when the network configuration is static, requiring constant overhead to resolve the transmission order. However, they do not work well in Research supported by National Aeronautics and Space Administration Grant NAG 1-613 and by National Science Foundation Grant MIP _PHONE_.

mobile networks in which stations can join and leave dynamically. For this reason, we study random-access schemes in this paper. One of the popular random-access schemes used in mobile networks today is DFWMAC, a CSMA/CA protocol selected as the IEEE 802.11 draft standard [4]. Collisions in this protocol are resolved by a binary exponential backoff algorithm, similar to that used in Ethernets. There are two problems associated with the use of the backoff algorithm. First, although the algorithm is fair in the long term so that every station has equal access on the average, it is not fair in the short term because it does not give equal access to all the stations competing for the channel. Oftentimes, a station that has just transmitted has a higher chance to access the channel again in the near future. This behavior may cause large variations in inter-channel access delays, an undesirable phenomenon in systems wishing to provide certain qualify of service in access. Second, the protocol does not operate efficiently in the presence of hidden and exposed terminals [8]. The backoff counters are updated incorrectly for stations involved, and do not reflect the local contention level. Our proposed wireless window protocol (WWP) is a limited contention protocol in which the set of contending mobiles are chosen based on a global common contention window maintained by every mobile. The contention window is adjusted based on three possible channel states: no transmission, success, and collision. We assume that the channel state at the end of each contention slot is broadcast by the base station in the downlink. Initially, each station generates a random contention parameter between zero and one based on a uniform distribution. Each station then derives a window with the goal of isolating exactly one parameter in the window. Since all stations derive the window boundaries using identical information and the same algorithm, the windows at all stations are synchronized. Depending on the state of contention (collision, idle, success) broadcast by the base station, stations update their windows in a synchronized fashion. Eventually, only one station is isolated in the window and transmits the message to the base station, which may forward it to another mobile in the same cell. Our protocol addresses the two problems associated with DFWMAC. Our analytical and experimental results demonstrate WWP's channel efficiency as well as its long-term and
short-term fairness. Further, as a base station always broadcasts reliable channel-state information to mobiles in the same cell, false interpretations of channel states in the hidden- and exposed-terminal scenarios are avoided in one cell. There are some implications in two-cell scenarios that are discussed in Section 3.
2. WINDOW-BASED WIRELESS WINDOW PROTOCOL FOR ONE CELL In this section, we present the design of WWP for a one-cell case. Section 2.1 gives an overview of the protocol. Since the key aspect of the protocol is the adjustment of windows based on the channel state and the current channel load, Section 2.2 discusses the dynamic-programming formulation of window adjustments. Section 2.3 presents WWP with lookahead technique. Finally Section 2.4 gives our analytical result on the inter-channel access delay.
WWP bears certain similarity to binary-tree splitting protocols proposed in wired domains in its contention-resolution process. According to the tree splitting protocol, when a collision involving  stations happens, the stations are randomly split into two subsets by flipping a coin. The stations in the first subset retransmit in the next slot, whereas the second subset must wait until all the stations in the first subset have succeeded. If the first transmission rule, i.e., when packets are transmitted for the first time, is incorporated, there are a few variants of the basic protocol. The most celebrated one, the epoch mechanism, was suggested by Gallager [6] and by Tsybakov and Mikhailov [1]. It achieves a maximum stable throughput of   .
2.1. Overview In this section, we describe the operation of our proposed window-based protocol. The protocol can be described in a two dimensional space as illustrated in Figure 1. The time space shows the progression of contention slots, and the parameter space defines stations that are eligible to contend. The operation of the protocol in one contention period consists of the following steps. 1. Parameter initialization. A station ready for transmission generates a random contention parameter in the parameter space. Without loss of generality, we assume that the parameters are generated from a uniform distribution between 0 and 1. New stations arriving before the beginning of a contention period must wait until the beginning of the next contention period. Since stations regenerate their contention parameters every time in the beginning of a contention period, each station has an equal chance of accessing the channel in each period. (This is different from ordered-access schemes that schedule accesses after generating the contention parameters once.)
The major difference between WWP and the epoch algorithm is that WWP is not a contention resolution algorithm in a strict sense. The objective of WWP is to fulfill one successful transmission in the least possible number of slots, whereas resolution algorithms resolve a whole set of stations that are involved in a collision before accepting new stations. Intuitively, contention-resolution algorithms may achieve higher channel efficiency, because they utilize information obtained from previous contentions. However, new stations suffer from longer delays. Our protocol achieves a balance between the channel throughput and the lag between the time when new stations join and the time when they are served.
2. Window estimation based on channel load. Each sta tion maintains a lower bound and an upper bound in the parameter space. (The bounds identify stations that can participate in the contention process.)
Initially,  and  . In addition, each station  computes  ,  , based on an estimated channel load. As each ready station starts with identi cal information and the same algorithm, , and  in all stations are synchronized.
There are two major advantages of WWP over the epoch algorithm. First, WWP does not put a stringent synchronization requirement on its implementation as the epoch algorithm. In the epoch algorithm, synchronization must be supported at least to the granularity of one tenth of a slot if one successful transmission requires four to five splits of the initial epoch. In WWP, synchronization is only required in the contention-slot boundary. Second, WWP does not adopt the Poisson arrival model as assumed by the epoch algorithm. As is well known, packet arrivals to the network cannot be modeled as a Poisson process since packets are bursty within connections, and the major part of the Internet traffic, such as Web surfing and ftp, is connection-oriented. The rest of the paper is organized as follows. Section 2 presents WWP in a one-cell scenario. Section 3 describes modifications to WWP in order to adapt it to cell overlays in a two-cell scenario. It also discusses the differences between WWP and its Ethernet counterpart. Section 4 presents the performance evaluations of WWP and compares it to DFWMAC in both the one-cell and the two-cell scenarios. Finally, Section 5 summarizes

Can static illusions be cast on and move with moving objects?
As a 20th-level Illusionist Wizard, I can make an illusion of:
- a functioning volcano (Mirage Arcane)
- or a ferocious monster (Major Image)
- that can even deal damage (Phantasmal Force)
But using an illusion spell, can I, for example:
- put an illusory sweater on my dog?
- put an illusory blade on the end of my normal wooden staff that follows the staff even while I use it? (it would look scary!)
- put an illusory vase on a table, which moves with the table if the table is pushed? (it wouldn't get knocked over, of course)
Note: This question is about the general function and utility of illusion spells as a school of spells in 5e rather than about a specific spell. If specific illusion spells give different answers, that is a valuable part of the answer to this question.
Illusions can be cast at a place on the ground, and they stay there unless the spell gives you the ability to move them.
If the ground moves, does the illusion move? Does the D&D world spin like Earth does or fly through space? If so, the illusion usually moves with the ground on which it was cast.
Can an illusion spell such as Minor Illusion or Silent Image be cast on an object such as a sword or a table? If that object is then moved, does the illusion move with it? What about an illusory hat on my ally's head?
Put another way, what is the reference frame in which an illusion is cast, and is this something the caster can choose?
Clarification: I am not asking if I can pick up an illusion and move it, only if the illusion can be attached to something other than a fixed point on the ground and what happens when that something moves. A Minor Illusion would still be a simple, stationary object sort of illusion.

Publisher: Thematic paper for the European Employment Observatory of the European Commission, Directorate General for Employment, Social Affairs and Equal Opportunities
This thematic paper for the European Employment Observatory investigates the quality of two macro-economic approaches which relate unemployment, output and inflation. The non-inflationary rate of unemployment (NAIRU) relates price and wage expectations in an equilibrium model. Okun's law describes the relation between unemployment and output. Both approaches have been challenged by the recent crisis. The paper concludes that this type of macro-economic modelling is hardly able to reflect basic behavioural and structural characteristics of the economies. Moreover, statistical estimation methods have limited capacities to mirror the theoretical principles. The two concepts are thus no adequate substitute to economic modelling.


In this guide, we'll set up an Active-Active database, formerly known as CRDB (Conflict-free Replicated DataBase) spanning across two Redis Enterprise Software clusters for test and development environments. Here are the steps:
 - Step 1: Run two Redis Enterprise Software (RS) Docker containers
 - Step 2: Set up each container as a cluster
 - Step 3: Create a new Redis Enterprise Active-Active database
 - Step 4: Test connectivity to the Active-Active database
To run an Active-Active database on installations from the RS download package, set up two RS installations and continue from Step 2.
Note:
This getting started guide is for development or demonstration environments. To set up an Active-Active database in a production environment, use the instructions for creating an Active-Active database.
Step 1: Run two containers
To spin up two RS containers, run these commands:
docker run -d --cap-add sys_resource -h rp1_node1 --name rp1_node1 -p 8443:8443 -p 9443:9443 -p 12000:12000 redislabs/redis
docker run -d --cap-add sys_resource -h rp2_node1 --name rp2_node1 -p 8445:8443 -p 9445:9443 -p 12002:12000 redislabs/redis
The -p options map the admin console port (8443), REST API port (9443), and database access port differently for each container to make sure that all containers can be accessed from the host OS that is running the containers.
Step 2: Setup two clusters
 1. For cluster 1, direct your browser to https://localhost:8443 on the host machine to see the Redis Enterprise Software web console. Simply click the Setup button on the page to get started.
 Note:
 Depending on your browser, you may see a certificate error. Continue to the website.
 getstarted-setup
 2. On the node configuration page, select your default settings and provide a cluster FQDN, for example cluster1.local. Then click Next button.
 getstarted-nodeconfig
 3. If you don't have a license key, click the Next button to try the trial version of the product.
 4. On the next screen, set up a Cluster Administrator account using an email for the login and a password.
 getstarted-admincredentials
 5. Click OK to confirm that you are aware of the replacement of the HTTPS SSL/TLS certificate on the node, and proceed through the browser warning.
Repeat the same operations for cluster 2 with these differences:
 - In your web browser, go to https://localhost:8445 to set up the cluster 2.
 - For the Cluster name (FQDN), enter a different name, such as cluster2.local.
Now we have two Redis Enterprise Software clusters with FQDNs cluster1.local and cluster2.local.
Step 3: Create a Redis Active-Active database
 1. After you login to cluster1.local, select the Redis database and deployment type Geo-Distributed. Then click Next.
 new_geo-distrbuted
 2. In create database, click the show advanced option and:
 1. For the database name, enter: database1
 2. For the endpoint port number, enter: 12000
 3. In the participating clusters list, add the address and admin credentials for:
 - _URL_ - the cluster you are currently connected to
 - _URL_ - the other cluster
 4. In Database clustering, either:
 - Make sure that Database clustering is enabled and select the number of shards that you want to have in the database. When database clustering is enabled, databases are subject to limitations on Multi-key commands. You can increase the number of shards in the database at any time.
 - Clear Database clustering to use only one shard and to avoid Multi-key command limitations.
 Note:
 You cannot enable or disable database clustering after the Active-Active database is created.
 3. Click Activate to create your Active-Active database.
 crdb-activate
 Note:
 If you cannot activate the database because of a memory limitation, make sure that Docker has enough memory allocated in the Docker Settings.
 4. After the Active-Active database is created, access the RS admin console of cluster 1 at https://localhost:8443 and of cluster 2 at https://localhost:8445.
 5. Make sure that each cluster has an Active-Active database member database with the name database1.
 In a real-world deployment, cluster 1 and cluster 2 would most likely be in separate data centers in different regions. However, for local testing we created the scale-minimized deployment using two local clusters running on the same host.
Step 4: Test the connection to your member Redis Active-Active databases
With the Redis database created, you are ready to connect to your database to store data. You can use one of the following ways to test connectivity to your database:
 - Connect with redis-cli, the built-in command-line tool
 - Connect with a Hello World application written in Python
Remember we have two member Active-Active databases that are available for connections and concurrent reads and writes. The member Active-Active databases are using bi-directional replication to for the global Active-Active database.
crdb-diagram
Connecting using redis-cli
redis-cli is a simple command-line tool to interact with redis database.
 1. To switch your context into the RS container of node 1 in cluster 1, run:
 docker exec -it rp1_node1 bash

 2. To use redis-cli on port 12000, run:
 redis-cli -p 12000

 3. Store and retrieve a key in the database to test the connection with these commands:
 - set key1 123
 - get key1
 The output of the command looks like this:
 127.0.0.1:12000> set key1 123
 OK
 127.0.0.1:12000> get key1
 "123"

 4. Enter exit to exit the redis-cli context and enter exit again to exit the RS container of node 1 in cluster 1.
 5. To see that the key replicated to cluster 2, repeat the steps to switch your context into the RS container of node 1 in cluster 2, run the redis-cli and retrieve key1.
 The output of the commands looks like this:
 $ docker exec -it rp2_node1 bash
 $ redis-cli -p 12000
 127.0.0.1:12000> get key1
 "123"

Connecting using Hello World application in Python
A simple python application running on the host machine can also connect to the database.
Note:
Before you continue, you must have python and redis-py (python library for connecting to Redis) configured on the host machine running the container.
 1. In the command-line terminal, create a new file called redis_test.py.
 vi redis_test.py

 2. Paste this code into the redis_test.py file.
 This application stores a value in key1 in cluster 1, gets that value from key1 in cluster 1, and gets the value from key1 in cluster 2.
 import redis

 rp1 = redis.StrictRedis(host='localhost', port=12000, db=0)
 rp2 = redis.StrictRedis(host='localhost', port=12002, db=0)

 print ("set key1 123 in cluster 1")
 print (rp1.set('key1', '123'))
 print ("get key1 cluster 1")
 print (rp1.get('key1'))

 print ("get key1 from cluster 2")
 print (rp2.get('key1'))

 3. To run the "redis_test.py" application, run:
 python redis_test.py

 If the connection is successful, the output of the application looks like:
 set key1 123 in cluster 1
 True
 get key1 cluster 1
 "123"
 get key1 from cluster 2
 "123"


Advice 1: How to twist the speedometer on the Gazelle
The Gazelle is considered to be one of the most popular cars in the domestic car market. It is often used for cargo transportation of small objects and loose mixtures, such as sand, cement, gravel and clay. The Gazelle is the production of the Gorky automobile plant and produced from 1994 to 2010.
How to twist the speedometer on the Gazelle
Instruction
1
The benefit and practicality of the car Gazelle is that to buy parts for it at almost every car market or auto-parts store. For example, if you broke down the speedometer, you can go to the market and buy a new one. This is one of the main advantages of a Gazelle compared to imported models of trucks. Sometimes there are situations when you need to roll the mileage on the smaller side. Most often this is done during the resale of a Gazelle to get her more money.
To twist the speedometer Gazelle, remove the box, get to the motor and through Rossica start to twist.
2
This is a very laborious and lengthy procedure. So be patient and twist the quantity of kilometers you need. Then remove the glass shield, which protects the speedo from mechanical damage, disassemble it and carefully loop the videos showing the mileage manually to your preferred value.
3
If your Gazelle has an electronic speedometer, as described above, the wrap is unlikely to implement. To do this, craftsmen invented a special device that will help you to solve this problem. Connect plus and minus to the electric circuit, the signal wire will go directly to the speedometer. Thus, it is possible to speed up and slow down the speed cheat. With electronic speedometer on the Gazelle does not suffer and with proper care will last you for years to come. Be careful as the use of such controller cheat mileage contrary to the Charter some transport companies. So you can not only be fired but put in jail.
4
The vast majority of modern gazelles equipped with an electronic speedometerAMI, so you still have to shell out for buying the device that controls the winding of the mileage. Usually wrapping the speedometerand is carried out in order to increase or to decrease the mileage which the car was driven since its purchase/sale.
Advice 2: How to increase the capacity of the Gazelle
Increase the capacity of the car "Gazelle", among other things, will help to reduce the costs of its operation. After the manufacturer has equipped its new high-performance engine and steering, the opportunity to increase the weight of cargo without sacrificing maneuverability and speed qualities.
How to increase the capacity of the Gazelle
You will need
 - Sets of wrenches of different types and sizes, the channel selected length and size, welding machine, angle fitting, skills and access to work with welding, an additional "root" leaves of springs, jacks or other lifting devices, chock, belay the "goats."
Instruction
1
The work consists of two main stages: the gain of the base frame and the cargo platform, installing additional spring leaves. Start with a building frame with the use of appropriate channel size and long. The channel will Waite in the inner part of the supporting frame or screw the bolts through existing frame holes. Instead of a channel can weld along the frame - with the inside or outside of the band of sheet metal. Increase lateral stiffness, with corners or fittings, pulling the opposite longitudinal part of the frame. Then you can move on to the second stage.
2
For installing additional spring leaves detach from the gearbox drive axle driveshaft, causing the chisel marks to ensure alignment for future Assembly. Remove step-ladders of springs and raise the car sufficiently to free springs high. After selecting and installing additional spring leaves, do operations of this step in reverse order: step ladders fasten the axle to the frame, and then fasten the driveshaft to the gearbox, aligning left when disassembling the label. Then do the operation of adding leaves and to strengthen the front springs.
3
After completion of the work check and, if necessary, adjust the toe-in of front wheels. In subsequent operation of the modernized "Gazelle" pay attention to increased wear of the brake pads, wheel bearings and hubs. Follow and nodes that you have made changes - it is likely that you will need to repeat from time to time the tightening of loose connections.
Note
At work, use caution. When welding disconnect the battery terminals. When you use lifts and jacks, use a safety "goats" and wheel shoes. Pay close attention to the possibilities of the damage vehicle wiring, brake pipes and hoses.
Changing the design of the car is subject to the corresponding registration in the registration authorities with mandatory changes to the technical documentation.
Useful advice
The stretcher and cargo platform improve, then screw bolts in the corners diagonally to the transverse spars.
Is the advice useful?

Gong Healing In Nepal
Overview of Gong Healing in Nepal
Gong is a musical instrument, which is played for spiritual blessings, meditation, and ceremonies. It is made by hand with love and care. It is also used for healing purposes. Gong healing in Nepal is a process of rinsing the whole body and mind of a person with the help of healing sound from the gong.
Gong healing in Nepal is a debatable topic to discuss around. It is very popular because of its positive effect on human health. Gong healing is a very simple process. Just put the gong into the play and the healing sound produced by gong will help you to experience one of the best chances in the world.
Gong Healing and Training in Nepal
When the gong is played softly, the soothing sound from gong helps to heal the individual and brings the necessary positive change in the body. The reason why gong is played softly is to create a relaxing sound instead of noise.
Actually, Gong healing in Nepal is done by laying down in a comfortable position and resting the whole body, mind, and spirit." Gong healing feels like a psychedelics journey without taking any psychedelics." Says, practitioners.
We provide Gong healing in Nepal to heal your mind and focuses on spirituality and recovery. Curing any disease with the help of gong will be far more beneficial than medical treatment. This is because gong healing not only cures symptoms but also will reduce every way for the disease to get back.
gonghow to play gong
Benefits of Gong Healing
Gong healing in Nepal has been so popular nowadays and the craze of people towards this is increasing. This is because of the benefits of gong healing. The benefits of gong healing are:
 1. Gongs are useful in solving emotional, spiritual, physiological, and physical distance.
 2. Healing of gong stimulates glandular, nervous, and exocrine systems.
 3. It is very helpful because it transforms worse emotional and mental conditions into better ones.
 4. Healing using gong is very useful to clear the negative thoughts from our minds.
There are so many advantages to the human health of gong healing. This is the reason why Gong healing in Nepal is getting hype.
How does gong healing work?
Gong healing is one of man's most powerful and oldest inventions in history. When the metal of gong is excited than the electrons become highly charged electromagnetically and forms a field of Plasmon.
Thus produced plasmon field is created off the gong and the listener hears the soothing sound. When the gong is revved up again, the plasmon field expands. Therefore, in this way when we strike the gong with a mallet, the sound is produced.
The sound produced by gong differs in a way that the mallet is struck into the metal. In general, gong produces three types of sound and they are dark, metallic, and majestic. It makes a resonant echoing sound. The peculiarly sonorous sound from gong is the best thing to heal disorders.
how to play gong
This healing offers not only the mediation process from gong but will also help an individual to grow up strong. The healing changes time and locality.
Gong healing is an ideal tool for stress reduction, stimulation of the glandular system, and to break up emotional blockages. When the gong is skilfully played, it resonates and stimulates all the human cells unblocking happiness hormones.
The gong healing generates powerful multi-dimensional ripples of sound that steams the whole body. The OM sound of gong healing creates total silence within.
Gong healing in Nepal has just got a platform but the graph is increasing rapidly. The craze of people towards this is growing steadily. Gong healing in Nepal should be promoted in the best way


text: A new approach for determining the orbital contribution to analytical derivatives of perturbation theory energies is presented. The usefulness of the new approach is demonstrated by application to closed-shell second-order Møller-Plesset perturbation theory (MP2). This new method is related to that used previously (Lee, T. J., and Rendell, A. P., 1991, J. Chem. Phys., 94, 6229) for analytical energy gradients of the closed-shell singles and doubles coupled-cluster method augmented with a perturbational estimate of the effects of connected triple excitations, CCSD(T), but it is more appealing in that potential singularities are rigorously eliminated. The computational savings for MP2 are modest (two n5 steps, where n is the number of molecular orbitals), but the savings for fourth-order perturbation theory (MP4) or CCSD(T) energy gradients (two n7 steps) are significant. Hence the new approach is less expensive than previous applications of analytical gradient theory to perturbation theory electron correlation energies, and it is numerically stable.

JULIUS PLANER: THE DISCOVERER OF LIQUID CRYSTALS (RENEWAL OF THE PRIORITY) (Yuliush Planer: pershovidkryvach ridkykh crystaliv (vidnovlennya priorytetu))
Languages of publication
The life path, research and teaching effort of Julius Planer has been by far overlooked by researchers in Ukraine. Therefore, the article represents an attempt to fill this 'blank spot', and to change the conventional view on the pioneering status of botanist Friedrich Reinitzer and crystal physicist Otto Lehmann in the discovery of liquid crystals. Also, the light is shed on important details in the biography of Julius Planer, with emphasis on his coming to Lviv (Lemberg) and work as a professor of Lviv University. It's shown that the historical truth is that Julius Planer, a professor of the Lviv University, as early as in 1861, long before Reinitzer and Lehmann, observed and gave scientific description of an optical phenomenon that later became an explicit classical feature of the liquid crystal condition of a substance. Detailed information is provided of what exactly was observed and described by Planer in his scientific paper 'Notiz uber das Cholesterin'.

Working with Reflex files
Writing reflexes requires a few tools. You'll need access to your favorite text editor, and the programs provided in the BrainStem support download. These tools include:
 - arc - The reflex language compiler
 - Python - The BrainStem python library can now load and unload reflex files.
The BrainStem support download can be obtained from the download page on the acroname website.
A Note about Directories
Acroname prefers to distribute a set of directories you can place anywhere on your system rather than rely on platform specific installation routines, and default program locations.
The BrainStem Support download includes the following directories:
 - acroname - Top level folder
 - bin - Executable apps and libraries
 - development - Examples and API libraries (Python and C++)
 - aInclude - Header files for reflexes
Arc the Acroname Reflex Compiler
Arc can be run from the command line. It will compile reflex source files from within the bin folder or from a relative file path (absolute paths will not work). The reflex files will be compiled into map files and placed into the local directory. Map files, which are binary byte code files are executed by the Reflex Virtual Machine on BrainStem modules.
$>./arc -h
This will print information about using the arc compiler. Arc has a couple of useful flags useful for working with reflex file output, but first let us look at the basic command line for compiling reflex files.
$>./arc ../development/reflex_examples/Blink_LED.reflex
This will read in the Blink_LED.reflex source file located in the development/reflex_examples folder, and produce the compiled result at bin/Blink_LED.map.
$>./arc -p ../development/reflex_examples/Blink_LED.reflex
This will read in the Blink_LED.reflex source file in the development/reflex_examples directory, and output the resulting tokenized output of the lexer portion of the compilation process.
$>./arc -a ../development/reflex_examples/Blink_LED.reflex
This will read in the Blink_LED.reflex source file located in the development/reflex_examples folder, and will output the AST for the reflex.
$>./arc -d Blink_LED.map
This will read in the compiled Blink_LED.map binary located in the bin folder, and will generate a .dsm human readable disassembly file in the bin directory. See Appendix IV: Reflex map file Disassembly for more information about understanding the format of the disassembly.
Loading reflex .map files with ReflexLoader
ReflexLoader is our new Command Line Interface (CLI) tool for loading .map files into any BrainStem device. It can be found in the BrainStem development kit under the bin folder.
$>./ReflexLoader -H
This will print the usage information for ReflexLoader. If you are having trouble getting something to work this is one of the best places to look for more information. One thing that is important to make note of is that specifying a device '-d' is required. Additionally, that means that you must also have a device (SN), store and slot specified. Failure to do so will cause the program to return an error. With that said a command is also required if you were wanting the program to actually do something; however, failure to include one will not cause an error.
$>./ReflexLoader -L -i /location/of/file.map -d 0x40F5849A INTERNAL 0
This command will load '-L' the input file '-i' /location/of/file.map to the device '-d' into the INTERNAL store at slot 0.
Unloading a slot is just as easy but instead of using the '-L' and '-i' you would use '-U' and '-o' to specify where you would like the file to go. ReflexLoader will not create any file paths that do not exist so you must give a valid path.
$>./ReflexLoader -E -d 0x40F5849A RAM 0
This command will enable '-E' the reflex that is loaded into the RAM store at slot 0 in the specified device 0x40F5849A. Keep in mind that although you can load a reflex into RAM it will not survive a power cycle as it is volatile memory.
To disable this slot just swap the '-E' for '-D'
$>./ReflexLoader -B -d 0x40F5849A INTERNAL 0
This last command will make a slot bootable. Once this has been set and a power cycle occurs the BrainStem device will automatically enable the reflex at the designated slot. In order to disable a boot slot you will need to replace the slot parameter '0' in this case with 255.
Loading reflex .map files with Python
The BrainStem python library can be used to load compiled map files onto BrainStem modules. To load .map files with python you will need to follow the installation instructions of the getting started guide in the Python section of this reference.
To load a reflex map file into a slot on your brainstem module. First compile the reflex with arc. The resulting map file can be found in your aObject directory. Then start the python interpreter, and import the brainstem package. Instantiate your module and connect. Once you're connected, the following code block will show you how to load, enable and disable the .map file.
>>> fh = open('path/to/map/mymap.map', 'rb')
>>> mapfile = fh.read()
>>> fh.close()
>>> stem.store[0].loadSlot(0, mapfile, len(mapfile)) #loads map into store 0 slot 0
0
>>> stem.store[0].slotEnable(0)
0
>>> stem.store[0].slotDisable(0)
The above code simply opens the map file for reading in binary mode, reads the contents of the file into the mapfile variable, loads that data into store 0 slot 0 and enables and disables the slot.
Boot Reflexes
You can also set your stem to enable the map file on boot. To do this you will need to load the map file into a slot on the internal store of your module (the internal store is index 0). Then set the boot slot on the module by accessing the setBootSlot procedure of the system module
>>> stem.system.setBootSlot(0)
0
>>> stem.system.setBootSlot(255) # will disable the slot from being enabled on boot.
If you do not have python installed on your system, you can also use the aConsole utility to load .map files.

I have a db and want to know if it contains any spatial tables. Is there a table in SQL Server that holds spatial metadata i.e. a list of all the spatial tables in the current db? Oracle has the user_sdo_geom_metadata, Postgis the geometry_columns. What about SQL Server? The only spatial metadata I found was the sys.spatial_references.

You can always resort to querying the INFORMATION_SCHEMA.TABLES and COLUMNS dictionaries to find out if there are tables that are spatially enabled.
share|improve this answer
Further to unicoletti's answer, here is a SQL query that will list spatial tables and their geometry columns:
 from information_schema.columns c join
 information_schema.tables t ON c.TABLE_NAME = t.TABLE_NAME
 AND t.TABLE_TYPE = 'BASE TABLE' where c.DATA_TYPE = 'geometry'
 order by c.TABLE_SCHEMA, c.TABLE_NAME
If you're looking for geography columns change the geometry to geography in the query.
Also bear in mind a single table can have several spatial columns so it will appear twice in the query.
share|improve this answer
The "appear twice in the query" issue can be solved by removing "c.COLUMN_NAME as COLUMN_NAME" from the query, and changing "select" to "select distinct". Also, to get tables that have either spatial type or both, the WHERE clause would be "WHERE c.data_type IN ('geometry','geography')" – Jonathan Van Matre Dec 16 '11 at 19:50

A female orangutan named Bonnie from the National Zoo in Washington DC knows how to whistle and she does it because she can. Bonnie's whistling was documented by Great Ape Trust of Iowa early last December. Her self-taught talent shed new light on the evolution of speech, said Bonnie's keeper Erin Stromberg. "Sounds aren't necessarily all genetic... they also can be behavioral or ecological, and they are also voluntary", Stromberg added. BBC picked up the story last Thursday.
Bonnie whistles because she feels like it, not because for potential food reward. Researchers thought that orangutans have a limited number of sounds that they can make, all are involuntary responses based on emotions or to avoid predators. Bonnie's whistling certainly changed this perception. It turns out that Bonnie's friend, Indah also knew how to whistle. Scientists believe that Indah learned how to whistle from Bonnie. Indah died in 2004.
Bonnie's vocal plasticity might be the answer for the evolution of speech in orangutans or even the great apes.

text: Tanglewood is on U.S. Highway 77 five miles northwest of Lexington in northwestern Lee County. The area was first settled in 1856 by the Rev. Hugh Wilson, who founded the String Prairie Presbyterian Church there. After the Civil War a small settlement began to develop around the church. The town is said to have been named by two sisters who were reading a book called Tanglewood Tales. A post office was opened there in 1880, and by 1884 Tanglewood had three churches, a public school, a steam gristmill and cotton gin, and a general store. The business district was originally a mile east of its present site. When the San Antonio and Aransas Pass Railway was built in the early 1890s it bypassed the town, so Tanglewood residents decided to move closer to the tracks. A new townsite was platted in 1894, and most of the structures were moved to the new location. Reverend Wilson's church was drawn by mules on large log rollers to its new site. After 1900 three general stores, three cotton mills, and a broom factory owned by Henry Kelley were in operation, and during the 1905–06 school year the public school enrolled forty-two students. In 1914 the population of Tanglewood was estimated at 100, but after the early 1920s the town began to decline. Membership in the Presbyterian church dropped, the church was dissolved in 1922, and its congregation moved to Dime Box. The population of Tanglewood was reported at seventy-five in 1925 but dropped to forty by the early 1950s, when the town had two businesses. In 1950 the school was consolidated with the Lexington Independent School District. The population of Tanglewood was estimated at forty-eight in the early 1970s, and at that time the community had a general store, an antique shop, a real estate office, and a Baptist church. The population was still reported as forty-eight through 2000.

An ongoing study in Yellowstone National Park seeks to measure the emissions of carbon dioxide (CO2) as a response to geologic activity and as a possible predictor of some geologic events. A story covering this study notes that researchers estimate that Yellowstone emits 45,000 tons of CO2 per day. That is about 16.5 million tons per year.
The EPA estimates that the average car emits between five and six tons of CO2 per year. So natural geologic activity in Yellowstone contributes CO2 equivalent to about 3 million cars. The current attempts by the EPA to limit CO2 emissions would be dangerous for the American economy, but they would have no impact on the millions of tons Yellowstone emits every year.
More seriously, the EPA regulations would also have little impact on the billions of additional tons of CO2 that China, India, and the developing world will emit each year in the decades ahead. As a result, the regulations would have damaging impacts on the American economy, but just like cap-and-trade restrictions, they would have negligible impact on world temperatures.

In Example 11.6 (Indonesian rice farm data) assess gain from introducing AR1 errors (in addition to unstructured errors) in both random and fixed effects bi models. Also find the posterior probabilities that farms 1 to 171 are the best – in terms of having highest bi after allowing for inputs. Which farm has the highest probability of being best?
Multiple comparison with the best To illustrate a multiple comparison model where both fixed and random effects approaches to the permanent subject effect may be relevant, consider data from Horrace and Schmidt (2000) applied to loglinear production functions. The observations are rice outputs for n = 171 Indonesian farms over T = 6 seasons with inputs being
1. metric variables: seed in kg (KGS), urea (KGN) and trisodium phosphate (KGP), labourhours (LAB) and land in hectares (LAND).
2. categorical variables: namely B P = 1 if pesticides used, 0 otherwise; VAR (1 if high-yield rice varieties planted, 2 if mixed varieties planted, 3 if traditional varieties planted); and BWS (1 for wet season).

Reunion, the land of filming, has never lived up to its name so well. At the initiative of the IRT, the young singers of Kids United came to Reunion to make a clip broadcast on social networks and on television. A clip that highlights the exceptional natural heritage of our island.
After 6 month of unprecedented crisis, Reunion Island partners with Kids United and UNICEF for the release of their new title "Sauver le monde" shot in Reunion Island. This project is the result of a partnership carrying the values of sustainable and responsible development as well as the necessary preservation of ecosystems for the youngest generations..
This Tuesday 13 October, the New Generation Kids United unveiled their new music video "Saving the world" entirely shot in Reunion Island. Produced in partnership with UNICEF and IRT, the clip highlights the landscapes and emblematic places of the intense island in order to raise awareness of the issues of climate change, protecting biodiversity and preserving the environment.
Kids United New Generation is a French music group formed by UNICEF in 2015. Composed of children and young adolescents recognized for their universal and unifying messages, it is driven by strong values and is among the most listened to by the youth target. They knew how to conquer children as their parents by their music always full of benevolence, tolerance and respect.
The clip highlights the exceptional natural heritage of Réunion, dont 42% of the territory is listed as a World Heritage Site by UNESCO.
It first aired on the Kids United YouTube channel which has over a billion views and 2.8 million subscribers then on television for twelve weeks on the channels of the M6 group (M6, W9 et M6 Music), co-producer of Kids United New Generation, ensuring high visibility for the destination.
Note that the clip is also relayed on the IRT's digital platforms which account for nearly 720.000 subscribers.

This shooting target are used for shooting practice with laser pistol. The laser gun is made of a modified laser pointer with a pistol handle and a pulse-shaped laser beam that resembles a bullet passing through.
This shooting target is made of a stainless steel cup. There is a hole in the center of the target paper, if the laser beam hits the center (bulls eye), then the laser beam enters the cup, and will be reflected. Since the target paper is smaller than the cup's mouth, the reflected laser beam can be seen as a luminous outer ring.
See the following video:
An electronic circuit can be applied to this shooting target to create chime sound like bell or like steel hit by a bullet when bullseye. See the following video:

The influence of sown wildflower strips on ground beetles and spiders (Carabidae & Araneae) in an intensively cultivated agricultural area "Grosses Moos", Switzerland
The study examined the influence of sown wildflower strips on ground beetles and spiders in Grosses Moos, apart of the Berner Seeland region of Western Switzerland and a former low moor that has recently changed to an intensively cuItivated agricuItural area. Three wildflower strips of differing ages sown in native wild and cultivated plant species were sampled by means of pitfall (funnel) traps from May to July 1999. Also, adjacent cereal crops at distances of 15 m (field edge) and 70 to 100 m (field centre) were investigated. More than 44,000 individual ground beetles and spiders in 123 species were recorded. One hundred and ten species were found in the wildflower strips, 85 in field edges and 82 in field centres. Activity densities of ground beetles and spiders were lowest in the wildflower strips. Many stenotopic grassland species occurred exclusively or primarily in the wildflower strips. The species communities of ground beetles and spiders in the field edges were influenced positively by the wildflower strips, and accordingly exhibited greater species diversity than the field centres. Wildflower strips provide suitable habitats for many ground beetIes and spiders species; they consequently contribute to increase species diversity and enhance beneficial species in the locations studied.

The combination of innovative mine planning, blast hole design, accurate timing and
some novel mining techniques will be used to reduce the blast-induced vibration by a
massive 80% at points of interest outside a European quarry's boundary. This will then allow the quarry to access untouched reserves closer to houses and other significant points of interest, which otherwise would be effected by blast vibration. The key to achieving this reduction in vibration is being able to very accurately simulate the outcome of a number of mining scenarios without blasting. Known as Advanced Vibration Management™ (AVM™), Orica's Blast Based Services business has developed a process by which actual blast waveforms from the quarry can be used with the various mining scenarios and computer modelling to simulate, with a high degree of confidence, the actual outcome of the blasts in the area specified. Many blast designs and techniques can be modelled, and the most effective vibration outcome is then adopted as the new blasting design. Using this design, the quarry will be able to demonstrate that they are able to mine with significantly lower vibration levels and satisfy their regulatory requirements. As this paper goes to print the quarry is preparing to fire the screen blast and test holes to validate the study's predicted outcome.

Kähler geometry of the universal Teichmüller space and coadjoint orbits of the Virasoro group
- 49 Downloads
The Kähler geometry of the universal Teichmüller space and related infinite-dimensional Kähler manifolds is studied. The universal Teichmüller space T may be realized as an open subset in the complex Banach space of holomorphic quadratic differentials in the unit disc. The classical Teichmüller spaces T(G), where G is a Fuchsian group, are contained in T as complex Kähler submanifolds. The homogeneous spaces Diff+(S 1)/Möb(S 1) and Diff+(S 1)/S 1 of the diffeomorphism group Diff+(S 1) of the unit circle are closely related to T. They are Kähler Frechet manifolds that can be realized as coadjoint orbits of the Virasoro group (and exhaust all coadjoint orbits of this group that have the Kähler structure).

The re-animated Captain Metropolis, now Soviet Super Soldier
Commissar Moscow Is a member of the October Guard and the Soviet counterpart to Captain Metropolis.
Fictional Character BiographyEdit
The mysterious Soviet super genius known as Rasputin had perfected a machine that could re-animate the dead. The recently deceased Nikolai Ivanovic Lebonchenski, a brilliant general, was chosen as the first subject. the experiment was a success, but the scientists believed that a fit, able body would be better suited. For reasons unclear as of this writing, Captain Metropolis was chosen, and he was assassinated by KGB agents in the summer of 1965 in what appeared to be a car crash. After transplanting the brain into the new body, Commissar Moscow was placed in the October Guard as its leader. However, the transplant was unstable, and eventually Gardner's corpse broke apart, taking Lebonchenski with it. After his death, leadership of the October Guard was returned to Rasputin.
Powers and AbilitiesEdit
Commissar Moscow has no super powers. However, he is an Olympic-level athlete and possesses valuable knowledge of Cold-War era Russian firearms.

Electrical Firing System - Firing Cables
Firing Cables
The type of firing cable used depends primarily on how many conductors is needed. Generally, 16 or 50 conductor cables are used, being this is the most common type of firing system configuration. Some systems are designed with a specific male/female polarity (i.e. one type solely used at firing system end and one type used at field module end) and some use the same sex connector for both ends. The specific polarity design usually used to imply the "direction" of the firing current and/or data signal (computerized system only); however, this is unnecessary in an analog (non-computerized) firing system, where there is not necessarily an "input" and "output" of the field module. In other words, you don't have to worry about which end of the cable goes where in an analog system which uses the same sex connector on both the slave and firing control module, ultimately saving you time during setup. In addition, firing cables can have a separate ground line secured to them for systems which are not internally grounded. See pictures below.

Developing Minds (Concepts for Critical Psychology)
- Psychology, neoliberalism and power
Beskrivelse: Development policy makers and practitioners are becoming increasingly sophisticated in their ability to target 'development' interventions and the psychological domain is now a specific frontier of their interventional focus. This landmark study considers the problematic relationship between development and psychology, tracing the deployment of psychological knowledge in the production/reproduction of power relations within the context of neoliberal development policy and intervention. It examines knowledge production and implementation by actors of development policy such as the World Bank and the neo-colonial state - and ends by examining the proposition of a critical psychology for more emancipatory forms of development. The role of psychology in development studies remains a relatively unexplored area, with limited scholarship available. This important book aims to fill that gap by using critical psychology perspectives to explore the focus of the psychological domain of agency in development interventions. It will be essential reading for students, researchers, and policy makers from fields including critical psychology, social psychology, development studies and anthropology.

01 Aug Satwiwa Native American Indian Culture Center
Greetings! Jose Gonzalez here 🙂 These photos are from my visit to Satwiwa Native American Indian Culture Center at Rancho Sierra Vista in Newbury Park, CA. "Satwiwa, which means 'the bluffs,' was the name of a nearby Chumash village. To reflect this heritage, Satwiwa Native American Indian Culture Center and Natural Area was established by the National Park Service in partnership with the Friends of Satwiwa" (NPS, 2015).Park Ranger Robert Cromwell and Archaeological Technician Austin Ringelstein gave us a tour of the area by leading us on a hike to an excavation site. Youth members of the Urban Archaeology Corps will be excavating an area which was once a Chumash rock oven. Antonio Solorio, the SAMO youth program coordinator, gave us a tour of the Satwiwa Native Plant Garden. We tasted several plants that were important for the Chumash and Tongva people.
The visit to Rancho Sierra Vista was amazing! It was wonderful to learn about the many uses plants served for Native American cultures as well as the continued use of many of these plants in modern society. There was lots of wildlife near the cultural center including a King Snake and a lizard. The King Snake gets its name because it is able to eat rattlesnakes which are prevalent in the area.

Making Unique Statements with Custom Embroidery and Screen Prints
Your desire to individualize your attire has never been more achievable than in today's world where custom embroidery and screen printing have become quite popular. Exploring custom embroidery printing designs could be an excellent way to start. The U.S. fashion market contributes a massive $380 billion to the global economy, out of which a significant proportion is driven by customization. Join within this unstoppable fashion trend by discovering how custom embroidery and screen prints can help you make your unique style statement.
The Art of Custom Embroidery
Embroidery, the art of decorating fabric or other materials using a needle to apply thread or yarn from marymaxim.com, originated thousands of years ago. Today, it serves as a means of personal expression on clothing and other textiles. Custom embroidery involves creating designs based on your specifications, allowing you to display what it is unique about your personality and style. It transforms ordinary garments into walking expressions of creativity, style, and individuality.
Screen Prints: A Versatile Option
Another major avenue for customization lies with Screen Printing. This method allows you to place graphics on various items such as shirts, hats, or bags. The process involves pushing ink through a mesh stencil to create your design consistently across various items. Due to its versatility and practicality, screen prints are popular amongst individuals and businesses looking for a cost-effective way of customizing their apparel.
Difference Between Embroidery and Screen Print
While both methods involve adding elements to fabric, there are key differences between embroidery and screen prints. Embroidery gives a raised, textured feel that appears elegant and high-end. Screen prints provide sharp, vivid images that embody great detail but lack the texture of embroidery. The choice between these two depends on the aesthetic you are aiming for with your customized pieces.
Considerations for Custom Embroidery
Before jumping into custom embroidery, several elements need consideration. The size and complexity of the design, fabric choice, and color palette are important factors. The intricacy of your design will ultimately affect the price and turnaround time. In addition, some designs may need adjustments to fit within the limitations of embroidery.
Key Factors for Screen Prints
When it comes to screen printing, choosing the right artwork, high-quality ink, and suitable fabric is critical. Additionally, understanding the cost implication associated with the number of colors in the design is essential because more screens are used for more colors which increase the cost. Therefore, thoughtful planning can help keep costs down and achieve the desired outcome.
Understanding Your Personal Style
The most significant factor when customizing any apparel is understanding your personal style. Do not settle for a design that doesn't resonate with your aesthetic. Whether you prefer bold graphics or subtle embroidery, ensure that it is always true reflection of who you are.
The Allure of Vintage Styling
An ongoing trend in customization focuses on vintage designs through either screen printing or embroidery. This style approach exudes a sense of nostalgia and timelessness that's increasingly popular amongst urban outfitters. If creating an old-school vibe aligns with your style statement, consider incorporating vintage designs in your customization process.
Fostering Brand Identity
Beyond personal style statements, custom embroidery and screen prints form a significant part of many businesses' branding efforts. By having their logo or tagline customized onto staff uniforms, companies create a coherent brand identity while offering consistent visual advertising.
Promoting Sustainable Fashion Choices
Customizing existing attire with embroidery or screen prints promotes sustainability as it gives a fresh lease of life to older clothing items. This eco-conscious practice reduces waste while delivering stunning, unique fashion pieces that contribute towards a sustainable future.
Customization as Gifts
Customized articles make perfect gifts. Whether it is a unique embroidered piece or a screen-printed t-shirt with an inside joke, such personalized gifts speak volumes about the effort and thought invested into them. It shows the recipient that you took time and care in crafting something specifically for them.
Profitability of Embroidery and Screen Print Businesses
Considering the surge in demand for custom apparel, if you possess an entrepreneurial spirit and an eye for design, starting an embroidery or screen print business can be profitable. Offering customized products will enable you to tap into this continuously growing market.
Engaging with Local Artisans
If customization seems daunting honestly, look into engaging local artisans to guide you. They are skilled at their craft and can help you execute your vision effectively. This method not only gets you a fantastic end product but also supports local businesses.
Including custom embroidery and screen prints into your wardrobe or business strategy allows you to make a unique style statement. Whether you aim for personal expression or brand promotion, investing in customization provides substantial yield in individuality and visibility while supporting the drive towards sustainable fashion.


A Model to Estimate L-Strut Strength With an Emphasis on Thickness
 loading Checking for direct PDF access through Ovid
Abstract
Importance
To perform and teach septorhinoplasty, one must have a principled understanding of the mechanics of the nasal septum. The thickness of the L-strut and how it changes septal strength have not been adequately quantified, yet calculating septal strength based on changes to thickness and size is vital in maintaining lasting nasal strength and integrity.
Objective
To establish standards for the nasal septal cartilage thickness, dorsal and caudal septum length, and Young's modulus. To provide a basis for quantitative, operative decision making, a mathematical model of L-strut strength is presented based on changes in thickness and width.
Design, Setting, and Participants
Nasal septal cartilages from 30 fresh cadavers were used to measure thickness at clinically relevant points and length of dorsal and caudal L-strut arms. The Young modulus was directly measured using a force gauge. Statistical analyses were performed to compare thicknesses in anatomically relevant areas. Using a cantilevered beam construct, the spring constant of the L-strut dorsal and caudal arms were estimated individually with width and thickness as variables.
Main Outcomes and Measures
Thickness, dorsal and caudal length, and the Young modulus of nasal septal cartilage. Spring constants of dorsal and caudal L-strut arms with different combinations of thickness and width.
Results
The mean (SD) age at death of the 30 cadavers was 79.2 (13.6) years (range 50-97 years). Of these, 17 (57%) were male, and 13 (43%) were female. The mean (SD) nasal septal cartilage thickness in the 30 cadavers was 1.45 (0.54) mm. Mean (SD) thickness of points along the 2-mm L-strut line was 1.49 (0.56) mm and was significantly thicker than points along the 5-mm L-strut line (mean [SD] thickness, 1.29 [0.52] mm) but significantly thinner than points along the 15-mm L-strut line (mean [SD] thickness, 1.68 [0.53]). Mean (SD) thicknesses of the posterior dorsal and caudal cartilage points were 1.52 (0.45) mm and 1.71 (0.69) mm and were significantly thicker than the anterior dorsal and caudal points (mean [SD] thickness, 1.28 [0.42] mm and 1.31 [0.44] mm, respectively). Mean (SD) dorsal and caudal L-strut arm lengths were 21.9 (3.7) mm and 20.9 (3.5) mm, respectively. The mean (SD) Young modulus was 2.03 (1.3) MPa. A model was generated demonstrating the thickness required to maintain a desired strength at a given dorsal or caudal arm width.
Conclusions and Relevance
Although thickness was not uniform throughout the nasal septum, there is a predictable pattern. Thickness of the L-strut contributes more to septal strength than does L-strut width. The model generated in this study can be used in planning, performing, or teaching the applied mechanics of septorhinoplasty.

I've been hearing the phrase "whose job it is to" quite often lately. Consider these two sentences:
 1. We have a guy whose job is to clean windows.
 2. We have a guy whose job it is to clean windows.
I would prefer the first one because of the less redundancy, though both sentences seem to be grammatically correct (are they?). What do you think about the grammar of these sentences? Is there any (subtle) difference in meaning (accentuation)?

3 Answers 3
"..whose job is to..." indicates that you're talking about a primary purpose of the person's job, whereas "...whose job it is to..." doesn't necessarily mean it's the primary purpose of their job (though it can be) but just that performing that particular task is that person's responsibility.
For example, in the case of the window-washers, if their full-time job is window washing, it's quite fine to say "A person whose job is to clean windows."
But, let's say you have a secretary at a company who, when clients come in for a meeting, is the person who is supposed to bring in coffee. You generally wouldn't say that "we have a woman whose job is to bring coffee to client meetings," because it makes it sound like she's a full-time coffee-bringer.
However, you could say that "we have a woman whose job it is to bring coffee to client meetings," because when that task has to be done, she's the one whose responsibility it is.

The version with it is the one most style guides will probably recommend. The other version is also acceptable, but it is probably considered less formal and less traditional by most. You will probably hear that one more often in casual speech.
To analyse the sentence, it helps if we transform the relative clause into a main clause and see how it works with and without it:
 1. (?) His job is to clean windows.
 2. It is his job to clean windows.
 3.? To clean windows is his job.
In the first sentence, his job is subject, because it comes before the verb. That works all right. It simply describes what his job entails, what he's probably doing every day. But for some reason I'd prefer the gerund here; the infinitive may be more acceptable in a longer sentence of this type; I'm not sure why:
1.a. His job is cleaning windows.
1.b. His job is to clean the windows of the Tower next Sunday, before the Queen arrives.
It may have something to do with balance inversion; to clean is only put after the verb here because of the long phrase that must come directly after it: otherwise, this phrase would go somewhere in the middle of the sentence, which would make it much harder to read.
Sentence 2 looks most idiomatic. I think the phrase "it is his job" is a fixed expression with a slightly different connotation: it is his duty to clean windows. You could say it puts focus on it is his job, presents it as the new and salient information—this as opposed to sentence 1, in which focus is on to clean windows.
The reason why this indicates different focus is that, in 2, to clean windows is subject, which is expressed by the place-holder subject it that points forward to to clean windows. In a regular sentence, the subject is topic (non-focus, known information) and the predicate has focus, so that fits nicely. In sentence 1, the predicate was is to clean windows, and indeed that is what the focus was on.
In sentence 3, to clean windows is subject; it is of the same type as sentence 2, except that the deferred subject is filled in at the place of the place-holder subject it. But then we are troubled by an entirely different problem: English usually doesn't like it when an infinitive with to is used as the (direct) subject. In this case, it doesn't look too good; that is exactly why place-holder subjects are used at all. We could use the gerund instead to get an acceptable sentence:
3.a. Cleaning windows is his job.
This would be just as fine as sentence 2, with similar focus on is his job.
Now let's return to the relative clause:
We have a guy whose job is to clean windows.
This would be of type 1 above, if you consider word order. It may be acceptable, but it doesn't sound as good as type 2 in formal language, at least not to me. This is probably for the same reason as concerning sentence 1 above.
We have a guy whose job it is to clean windows.
This is of type 2, and it sounds better. That is probably because it is his job is a fixed expression and focus is in the right place. It may not be entirely evident that what applies to a main clause carries over to a relative clause, but I think it is a fairly reasonable hypothesis.
share|improve this answer
They're both grammatically correct. They're also almost identical in meaning.
There's room for suspicion that someone whose job is to clean windows has no other job, but someone whose job it is to clean the windows might have other jobs too when not discussing cleaning windows. But that's extremely tenuous; I'd not want to make an argument based on that fine a distinction.
