How to Restrict IP Addresses from Accessing your Web Server using .htaccess
17/04/2019 Comments off
If you are running the Apache Web Server or your web hosting provider running Apache based web server, you can use .htaccess configuration file to restrict access to your website. This could be a very important issue from security stand point of view especially if your server is being attacked or hacked from any specific or range of IP addresses.
Now, restricting access method works in two ways. First, you can restrict access to certain IP addresses and allow others. Second, you can restrict access to everyone but few IP addresses only. On this post, I will focus on both method and will try to explain as much as I can.
Restrict Certain IP Addresses
If you want to restrict specific IP addresses from accessing your site, you can use the following lines on your .htaccess file.
order deny,allow
deny from 123.4.5.6
deny from 654.3.2.1
allow from all
These lines above will block "123.4.5.6" and "654.3.2.1" IP addresses from accessing your site. You can add as many IP addresses as you want on this "deny from" list. One interesting fact is, Apache web server gives you lot more flexibility in terms of blocking IP addresses. Take a look at the following lines.
order deny,allow
deny from 123.4.5.
allow from all
If you observe it carefully, you will see that the fourth set of digit is missing on this IP address. It means, if any IP address that matches the first three set of digits will be blocked. So basically anyone with IP address like "123.4.5.1" or "123.4.5.244" won't be able to access your site as in both IP address matches with the first three (123.4.5.) sets of digits blocked by the Apache web server.
Allow Specific IP Addresses
Think of about a site that you built for a very specific purpose and for very few people, where you do not want everyone to show up. Apache allows you to do that as well.
For an example, lets assume that you built a site that you want one of your friend to be able to access and his IP address is "123.4.5.12". Simply write the following line on your .htaccess file and you are good to go.
order allow,deny
allow from 123.4.5.12
deny from all
In this case Apache will block all IP addresses except your friends IP address. This is as simple as it can get and I hope you got the basic idea.
Note: On all of my example I used either "allow from all" or "deny from all" at the bottom, this is very important. You must declare either one of these line based on your requirement or things might get little more complicated.
Also remember that all blocked IP addresses would be forwarded or shown an "403 Forbidden" error message. You can definitely customize this message as well but that's something I will talk about in another post.

How to configure virtual hosts in Apache HTTP server
12/04/2019 Comments off
Source: Xmodulo
Virtual hosting refers to the technique that allows a physical server to host more than one website domain (e.g., site1.com, site2.com). Virtual hosting is prevalent in shared web hosting environments, where typically hundreds or more of websites or blogs are packed on a single dedicated server to amortize server maintenance cost.
You are not a web hosting company? Sure, virtual hosting can still be useful to you. For example, you can place multiple websites of yours on one VPS that you rent out, saving on your VPS cost. To serve multiple domains on a VPS, you just need to configure as many virtual hosts on its web server, and point the domains to the static IP address of your VPS.
Due to its usefulness, virtual hosting is supported by all modern web server software such as Apache, Nginx, Lighttpd, IIS. In this tutorial, I will demonstrate how to create and enable virtual hosts in Apache HTTP server under Linux environment. There is slight difference in the configuration between Debian-based and Red Hat-based systems. I will highlight the difference along the way.
Before I start, I assume that Apache HTTP server is already installed on your Linux server. If you haven't, refer to our tutorials for Debian or Red Hat based systems, and install Apache server before proceeding.
As an exercise, let's create a virtual host for domain abc.com on Apache web server.
Step One: Create Document Root Directory for Abc.com Domain
Start by creating a directory which will hold the web pages for abc.com. This directory is known as « document root » for the domain. Following the common practice, let's organize all document root directories under /var/www, and name them after the corresponding domains. Also, create a dedicated log directory for abc.com under /var/log.
$ sudo mkdir /var/www/abc.com
$ sudo mkdir /var/log/apache2/abc.com (Debian, Ubuntu, Mint)
$ sudo mkdir /var/log/httpd/abc.com (Fedora, CentOS, RHEL)
Create a test webpage for the domain:
$ sudo vi /var/www/abc.com/index.html

 <title>Welcome to Abc.com</title>

Sample page

 This page is powered by Apache Virtual Host!

Change the ownership of the document root directory to the user that Apache web server runs as.
On Debian, Ubuntu or Linux:
$ sudo chown -R www-data:www-data /var/www/abc.com
On Fedora, CentOS or RHEL:
$ sudo chown -R apache:apache /var/www/abc.com

How to live stream video from webcam on Linux
11/04/2019 Comments off
Source: Xmodulo
Have you ever wanted to live stream a video feed from your webcam for someone else? You could use any existing video chat software such as Skype, Google+ Hangouts. However, if you do not want to rely on any third-party streaming infrastructure, you can set up your own webcam streaming server in house.
In this tutorial, I will describe how to live stream video from webcam by using VLC. VLC is an open-source, cross platform media player which can handle virtually all video and audio formats. VLC can also run as a streaming server supporting various streaming protocol such as RTP, HTTP, RTSP, etc.
Before attempting to set up webcam streaming on your own, you need to understand the huge potential security risk of streaming a webcam over the Internet. Anyone can tap into your streaming feed unless you properly access control the streaming server, and encrypt the streaming traffic. I'll briefly mention several security protections against threats towards the end of the tutorial.
Install VLC on Linux
Before setting up a streaming server with VLC, install VLC first.
To install VLC on Debian, Ubuntu or Linux Mint:
$ sudo apt-get install vlc
To install VLC on Fedora, first enable RPM Fusion's free repository, and then run:
$ sudo yum install vlc
To install VLC on CentOS or RHEL 6, first set up EPEL repository, and then use the following commands:
$ cd /etc/yum.repos.d/
$ sudo wget _URL_
$ sudo yum install vlc
Verify Webcam Device on VLC
Next, verify whether a webcam device is successfully detected on your Linux system and VLC.
To do so, first find out the device name of your webcam with the following command. In this example, the device name of the webcam is /dev/video0.
$ ls /dev/video*
/dev/video0
Now use the following command to test video from your webcam. Replace « video0 » with your own device name.
$ vlc v4l2:///dev/video0
If your webcam is successfully detected by VLC, you should see a video stream of yourself.
Configure Webcam Streaming on VLC
Assuming that your webcam is successfully recognized by VLC, I am going to show how to configure webcam streaming. In this setup, webcam is streamed over HTTP in WMV format.
To configure VLC for webcam streaming, first launch VLC.
$ vlc
Choose « Streaming » from VLC menu.
9652347212_67126e2037
On the screen, choose webcam/audio device name (e.g., /dev/video0 for webcam, and hw:0,0 for audio). Click on the checkbox of « Show more options ». Make a note of value strings in « MRL » and « Edit Options » fields. We will use these strings later in the tutorial. Click on « Stream » button

Specific parameters and variables used by Nakanishi and Koyaguchi (2008) are indicated by the [NK model]
Definitions and values for the dimensionless parameters are listed in Table 1.
Mathematical analysis of the system behavior
For dp/dt, Eq. (14) indicates that its sign changes from positive to negative with increasing Q beyond \( {Q}^{\prime }={Q}_{\mathrm{in}}^{\prime }/\alpha \). For dQ/dt, Eq. (15) depends on the value of x relative to \( {H}_{\mathrm{w}}^{\prime } \). By combining Eqs. (16) and (18), we rewrite Eq. (15) as
$$ \frac{\mathrm{d}{Q}^{\prime }}{\mathrm{d}{t}^{\prime }}=\left\{\begin{array}{c}\ \frac{1}{\mu_{\mathrm{E}}^{\prime }}\ \left[\ \left({\mu}^{\prime }{W}^{\prime }-\alpha \right)\ {Q}^{\prime }+G{W}^{\prime }+{Q}_{\mathrm{in}}^{\prime}\right]\equiv {F}_1\left({Q}^{\prime}\right)\kern2.25em \left({x}^{\prime }<{H}_{\mathrm{w}}^{\prime}\right)\\ {}\ \frac{1}{\mu_{\mathrm{E}}^{\prime }}\ \left[\ {\mu}^{\prime}\left(1-\varGamma \right){Q}^{\prime 2}+\left(G-\alpha \right){Q}^{\prime }+{Q}_{\mathrm{in}}^{\prime}\right]\equiv {F}_2\left({Q}^{\prime}\right)\ \left({x}^{\prime }={H}_{\mathrm{w}}^{\prime}\right).\end{array}\right.\kern0.5em $$
(19)
F1(Q) indicates that as Q increases from 0, it will converge to a constant flux, satisfying F1 = 0, which is shown to be always less than \( {Q}_{\mathrm{in}}^{\prime }/\alpha \). This condition indicates that pressure will increase while \( {x}^{\prime }<{H}_{\mathrm{w}}^{\prime } \), due to the increasing mass of gas within the chamber. When \( {x}^{\prime }={H}_{\mathrm{w}}^{\prime } \), the quadratic function F2(Q) controls the behavior of Eq. (19). We set Γ to equal 0 or 0.86 (Table 1), so that 1 − Γ > 0 is always satisfied. The discriminant of F2(Q) is given by
$$ D={\left(G-\alpha \right)}^2-4\ {Q}_{\mathrm{in}}^{\prime }{\mu}^{\prime}\left(1-\varGamma \right). $$
(20)
When G > α, Q is unstable because for Q > 0, F2 is always positive and monotonically increases. Therefore, Q increases consistently and will not converge on a fixed value. When G < α and D < 0, F2 is always positive and Qcontinuously increases. If D > 0, Q increases and converges on a value that satisfies F2 = 0. The boundary defining whether or not Q will continuously increase (G < α and D = 0) is a function of Qin and Vc and is shown in Fig. 4c. Compared with the experimental data, we find that STW are observed above this boundary. The same boundary, calculated without including the surface tension term (Γ = 0), is also shown in Fig. 4c. Our results indicate that this boundary is sensitive to the effective viscosity used in the model.
Calculation method
Equations (1), (6), (10), and (11) are solved numerically using the Runge–Kutta method (Fig. 8). Here we use dimensional variables to allow direct comparisons with experimental data. The values of L, x, Q, and p at the beginning of a cycle are referred to as "initial values" and are indicated by the subscript i. Sequential photographs in which a liquid slug is reproduced at the bottom of the pipe indicate that L∗i and xi are equal to 2 mm. Parameter Qi is assumed to be 0, meaning that pi represents the hydrostatic pressure in the pipe (pi = ρgL∗i). The transition from slug-to-annular flow is regarded as occurring at L = 0, and slug reconstruction is assumed to begin immediately. The time required to form a new liquid slug is calculated by considering the conservation of liquid volume in the pipe. The new liquid slug grows as it is fed by downward film flow at a constant volume flux of ∣(1 − α)W∣. When it reaches a volume of πr2L∗i, slug reconstruction is completed and a new STW cycle begins.
Fig. 8
Example of numerical results for Qin = 0.15 cm3/s and Vc = 180 cm3; black solid line is for ξ = 1.11 × 106 (Γ = 0.86) and dotted line is for ξ = 0 (Γ = 0). Time=0 corresponds to the time when slug flow starts to ascend. a Excess pressure. b Head position of the liquid slug. Blue line indicates Hw. c Flux in the pipe. d Total liquid slug length
The model periodicity is defined by the duration from a completion of liquid slug formation to the next. For comparison with the experimental results, the model amplitude is evaluated using RMS. We removed the mean pressure change before calculating RMS.
Periodic STW and non-STW
Examples of the numerical results are shown in Figs. 8 (one cycle of STW) and 9a (periodic STW). The calculated period and RMS values are indicated in Fig. 4a, b by broken lines. They are smaller than the experimental results by a factor of 2 to 3. We suggest that this discrepancy results from the development of surface disturbances during downward film flow, which effectively increases the growth rate of the liquid slug length (dL/dt). To test this hypothesis, we applied a model with an arbitrarily large w (average downward film velocity) so as to magnify dL/dt. When using a larger value of w that is 1.6 times that calculated by Eq. (23), the model fits both the trend and magnitude of the period and RMS of the experimental results under conditions producing periodic STW (Fig. 4a, b, solid lines). However, the model still overestimates the period and RMS, especially under non-STW conditions. This discrepancy may be explained by our choice to disregard a layered structure by assuming only one large liquid slug, L (Fig. 7a), exists. The period of pressure change is better correlated with successive reconstruction and/or burst cycles of the layered structure (Fig. 6b).
Fig. 9
Numerical results with random initial conditions for each cycle. a Periodic pressure cycle with constant initial conditions. b Initial liquid slug length varied in the range 0.1–1.0 mm. c Liquid slug growth rate varied by setting 1–5 times larger value of w for 0.5 s after 2 s from the beginning of each cycle. d Slug reconstruction site varied in the range 0–180 mm from the bottom of the pipe assuming halfway reconstruction
Nonperiodic STW
Our model cannot explain nonperiodic STW (Figs. 3e and 6c) as each cycle is assumed to start with the same initial values. Figure 6c (e.g., t = 74 – 75 s) shows slug reconstruction within the middle of the pipe (hereafter termed "halfway reconstruction"), which is only observed during nonperiodic STW. We infer that large surface disturbances, resulting from violent liquid slug membrane rupturing under large Qin, grow rapidly and induce halfway reconstruction.
Figure 9b–d shows the waveforms and periodicities with variable initial conditions among different cycles. STW cycles are stable provided


positive and negative connotations. Clinical trials in numerous species of animals including humans were conducted to determine if olestra would affect the utilization and absorption of macro- and micronutrients; the effects of olestra on growth, reproduction, or its toxicity were also examined. The roles of olestra as a fat substitute, how it could effect on humans and the environment, and the potential impacts from its use in large amounts were assessed. Olestra can be removed from the environment by aerobic bacteria and fungi which may be isolated from activated sludge and soils. _URL_:/67531/metadc2240/

NAIROBI, December 1 – Farmers on Monday asked the government to increase the purchase price of maize, saying better prices would help reduce the cost of flour.
A member of The East African Grain Council James Bett said current prices being offered by the government were uncompetitive resulting to farmers hoarding their produce.
National Cereals Produce Board (NCPB) was buying maize at Sh1700 for a 90 kg bag, against farmers' wishes for at least Sh2500 per bag.
Bett revealed that between 50 and 80 percent of the country's maize crop was yet to be harvested and therefore the shortage that could be fuelling the increase in prices may be artificial.
"You know in the last two to three weeks it's been raining heavily and this has inhibited some farmers from finishing the harvesting process," he said.
He added that in areas like Trans Nzoia where many farmers had already harvested their crop, rains were hampering the drying process. "You will see maize being dried on the roads and stadium; people are trying to dry the maize because the millers are not accepting high moisture content," Mr Bett said.
The farmer's organisation urged the NCPB to offer free drying facilities in order to absorb the maize that was still being held by farmers.
The Grain Council also said it did not expect the price of maize flour to go below Sh50, citing high production costs.
Francis Kariu, a researcher, said the most efficient price of production for a bag of maize for this season was Sh1, 400 per bag not including the cost of transport.
The Council which represents the interests of farmers, millers and traders is recommending a policy shift that would allow all interested parties in the sector to work out the best price mechanism.
"You see as long as the government keeps on meeting one group at a time obviously everyone will be keener on selling their agenda or having their case heard leading to conflicting resolutions," said David Nyameino the Chief Executive Officer of Cereal Growers Association.
The growers have further demanded that the government allow the private sector to carry out the importation of maize, and only after checking that all locally-produced maize had been exhausted.
"It will be unfair to go out there and purchase maize while that which has been grown here is yet to be bought," Mr Nyameino stressed.
The government has so far announced plans to import five million bags of maize to ease the shortage being experienced in the country.

Presentation on theme: "Our Children on Water An international art exhibition of children's paintings on water and the vital role of chemistry in providing this safely and sustainably."— Presentation transcript:
Our Children on Water An international art exhibition of children's paintings on water and the vital role of chemistry in providing this safely and sustainably We would like to build on the highly innovative exhibition by the children from Room 13 in the Sapebuso School in Soweto, South Africa, where children were asked to express their thoughts on the following question in their paintings: "Water is a resource that we all need everyday. Tell us how you and your family collect, store and use water, and how you feel about water." The resulting collection of paintings displayed breathtaking imagination and showed that the children were able to view water from many different, thought-provoking perspectives.
The Idea We propose to continue this art exhibition with paintings from children from other parts of the Pan African Chemistry Network, including Nairobi in Kenya and Addis Ababa in Ethiopia. This would be enhanced by paintings from children in well-known European locations, such as London, Madrid, Bratislava, Berlin, Budapest, etc – countries which face different challenges in providing their citizens with clean sustainable water. Such a collection of paintings, if prominently displayed and strongly promoted, would draw attention to the work of scientists in industry and academia in providing safe and clean water for people across Europe and in Africa. This project would be pan-European, and would have the potential to make inter-continental links to African countries. It would enable the chemistry community to shine a light on the many international projects on sustainable water that exist.
Making it happen The scale of the exhibition would depend on the number of participants, with each country encouraging local children to create a set of paintings on the theme of water, and arranging exhibition space in a well-known location. We expect that the total exhibition would include between 100 to 200 paintings. Once this has been defined, a schedule will be agreed for the tour, which would include African and European locations. The experienced communications team at the RSC would work with partner societies in each participating country to maximise publicity. In order to make this possible, we will be seeking funding from our industrial partners to cover the costs of this project. We will leave you with some more images from Soweto….

Common Sense was first produced in Edinburgh in 1987. It offered a direct challenge to the theory production machines of specialised academic journals, and tried to move the articulation of intellectual work beyond the collapsing discipline of the universities. It was organised according to minimalist production and editorial process which received contributions that could be photocopied and stapled together. It was reproduced in small numbers, distributed to friends, and sold at cost price in local bookshops and in a few outposts throughout the world. It maintained three interrelated commitments: to provide an open space wherein discussion could take place without regard to style or to the rigid classification of material into predefined subject areas; to articulate critical positions within the contemporary political climate; and to animate the hidden Scottish passion for general ideas. Within the context of the time, the formative impetus of Common Sense was a desire to juxtapose disparate work and to provide a continuously open space for a general critique of the societies in which we live. – May 1991 editorial
The life of Common Sense began in 1987 and ended in 1999 after the publication of 24 issues. Since then, a selection of articles from the journal have been republished in the book, Revolutionary Writing, and a few have been collected on libcom. Despite the journal's significance in the development of open and autonomous Marxist critical theory, a complete set of issues has been difficult to source, until now. You can read how the digitising got under way and a few notes on the scanning process itself.
The complete set of issues that were kindly donated by past Common Sense editors for the digitisation project has been deposited with the British Library for preservation. A further set is held by the National Library of Scotland.

I always find it interesting that 3D printers — at least the kind most of us have — are mostly open-loop devices. You tell the head to move four millimeters in the X direction and you assume that the stepper motors will make it so. Because of the mechanics, you can calculate that four millimeters is so many steps and direct the motor to take them. If something prevents that amount of travel you get a failed print. But there is one part of the printer that is part of a closed loop. It is very tiny, very important, but you don't hear a whole lot about it. The thermistor.
The hot end and the heated bed will both have a temperature sensor that the firmware uses to keep temperatures at least in the ballpark. Depending on the controller it might just do on-and-off "bang-bang" control or it might do something as sophisticated as PID control. But either way, you set the desired temperature and the controller uses feedback from the thermistor to try to keep it there.
If you print with high-temperature materials you might have a thermocouple in your hot end, but most machines use a thermistor. These are usually good to about 300 °C. What got me thinking about this was the installation of an E3D V6 clone hot end into my oldest printer which had a five-year-old hot end in it. I had accumulated a variety of clone parts and had no idea what kind of thermistor was in the heat block I was using.

Police break up anti-nuclear Red Square protest
MOSCOW (Reuters) - Russian police on Wednesday dragged away
activists protesting on Red Square against atomic power on the
20th anniversary of the Chernobyl disaster.
Thirteen young protesters from Greenpeace chained
themselves to railings around St Basil's Cathedral, a central
Moscow landmark famous for its multicoloured onion domes,
before plain clothes agents told them to move on.
Unsanctioned protests are forbidden on Red Square, which
was a favorite gathering place for Soviet dissidents. The
leather-jacketed agents and uniformed Kremlin guards used bolt
cutters to unchain the activists, whom they dragged away.
The 13 activists were wearing yellow t-shirts with
individual letters that, when taken together, spelled out "No
to Chernobyls" in a reflection of green groups' opposition to
world plans to build a new generation of nuclear reactors.
Russia is planning 40 more reactors, and is still using 11
reactors of the type used at Chernobyl, which was the world's
worst civilian nuclear disaster, spewing radiation across
The agents also led away photographers and cameramen
filming the protest. "They said they were not detaining us,
just taking us away for a conversation," one photographer said.
The main events marking the anniversary of the disaster are
taking place in Ukraine -- home to the remains of the power
station's fourth reactor which contaminated swathes of
territory in Russia, Ukraine and Belarus.
Concerns over soaring global energy needs and security of
fossil fuel supply have put nuclear power back at the heart of
the global energy debate despite the risk of Chernobyl-like
disasters and the nuclear waste that humanity will bequeath to
future generations.
Both Russia and the United States have called on fellow
industrialized powers to embrace nuclear energy to guarantee
stable supplies and cut greenhouse gas emissions.

May 15, 2008 Researchers in Israel have found that teenagers' values helped determine whether or not they engaged in violent behavior at school, especially in schools where violence was common.
The researchers are from the Hebrew University of Jerusalem. The researchers gave questionnaires to 907 Jewish and Arab teenagers in grades 10 to 12 who attended 33 schools in Israel, where Jewish and Arab children attend two separate public schools systems. The teens answered questions about the importance of 10 different values and about their own violent behavior. Values were defined as goals and ideas the students saw as important and guiding principles in their lives. Violent behavior was defined as actions like hitting and threatening. The prevalence of violence in the schools was estimated by averaging, in each school, adolescents' reports of their own violent behavior, violent behavior by their two best friends, and the violence they had encountered at school.
In both Arab and Jewish schools, adolescents who valued power (trying to attain social status by controlling and dominating others) reported more violent behavior than their peers. Teenagers who valued universalism (promoting understanding, appreciation, tolerance, and protecting the welfare of all people and nature) and those who valued conformity (limiting actions and urges that might violate social expectations and norms) reported less violent behavior than their peers. The association of power and universalism with teenagers' behavior was especially strong in schools where children's exposure to violence was relatively common.
According to the researchers, the study's findings highlight the protective role of values, in the same way that personality and family can be protective. In high-risk environments like violent schools, adolescents who place a low value on power and those who place a high value on universalism may be relatively protected against engaging in violent behavior. This could happen, the researchers suggest, because as teenagers become more aware of violence, their values are more likely to guide their behavior.
"It has always been a major goal of developmental research to understand the causes of violence," says Ariel Knafo, assistant professor of psychology at the Hebrew University of Jerusalem and the lead author of the study. "The current study, focusing on a life period considered crucial to the development of values, shows the importance of values considered in the educational context. The results suggest that programs that promote universalistic values at the expense of power values, if properly implemented, may help reduce adolescents' violent behavior."

The Milwaukee Art Museum may have a small collection of ancient Mediterranean art, but we have some great pieces!
Take, for instance, our two ancient Greek Hydria. Walk into Gallery 1, and you will see them in the free-standing case on the right.
What is so exciting about Greek vases? Well, for one thing, they are some of the only artwork that we have remaining from this important ancient civilization. In particular, their decorations are the only hint that we have of what ancient Greek painting looked like. Practically all ancient painting has been destroyed due to its fragility. Greek vases survived because they were put into tombs and sanctuaries as offerings. In fact, the accident of their survival has made them more important to us than to the Greeks, who for the most part did not seem them as great art and used them as everyday objects.
Also, Greek vases often show scenes related to mythology and can be a great way to learn how to identify the gods and heroes of the ancient world. Other vases show special events or everday activities that give us insight into the world of the ancient Greeks.
Circle of Antimenes Painter (Greek, Attic, active ca. 530–ca. 510 BC). Hydria (Water Jar), ca. 525 BC. Black-figure terracotta. Gift of Mr. and Mrs. Everett N. Carpenter to the Milwaukee Art Museum. Photo credit Larry Sanders
Our hydria would have held water (think hydration—the Greek word for water is the root for this English word). A rope could be strung through the two side handles for drawing water from a well or pool and also for carrying it, and the single handle on the back would be for pouring like a pitcher. The wide lip at the top was designed to stop drips.
What is really exciting about the Museum's hydrias is that they offer a perfect way to compare two different ancient Greek decorating styles, in person, on actual ancient objects.
For instance, one hydria is in "black-figure" and the other is in "red-figure." You can probably guess which is which. Both styles use the same "paint," called slip, which is a glaze made from clay. But they use it in very different ways.
In black-figure (above right), the slip is used to fill in the figures so that the details have to be scraped into the slip to show the red clay behind. Details in white and red paint might also be added after firing. The resulting silhouettes create a stiff, static figure. Also, overlapping objects is extremely difficult, as you can see from the two figures on the left—the scraped lines become a jumble. Also typical of black-figure vase paintings is a stage-like setting, often in a box, on one side of the vase. The black-figure technique reached its height in Athens during the late 6th century BC, which is when our hydria was painted.
Our black-figure vase shows an assembly of gods and not a specific myth. Recognizable by their attributes, Dionysus appears on the left with his long robe and beard; a youthful Apollo is seated in the middle with flowing hair and a lyre; and Hermes, on the right, is outfitted in his short cloak, winged boots, and traveler's hat. The two women may be Artemis and Leto, Apollo's sister and mother. Notice that if Apollo stood up, that he would be a full head taller than the other figures! This use of scale shows that he is the most important figure in the scene.
Red-figure vase paintings are created in a manner opposite to black-figure. The figures are outlined and the background is colored black. Rather than inscribing details with hard tools, the artist could use brushes to add details, which gives drapery, anatomy, and faces a more naturalistic appearance. Emotions and action were also easier to show. Just compare the overall appearance of these two vases, and you can see how freeing the red-figure technique is. There is more movement in the figures, who run across the ground line, and they are not constrained to the box on the front of the vase and fill the widest point on the vessel all the way around. The red-figure technique was developed in Athens during the late 6th century BC, but did not become dominant until after 500 BC. Our red-figure hydria (above left) was painted ca. 460 BC by the Niobid Painter. We know few personal names of Greek vase painters, so these anonymous artists are often given names related to a specific vase in their style. The Niobid Painter is named after a famous vase in the Louvre
In contrast to the scene on the black-figure hydria, the red-figure hydria has a narrative myth. Boreas, the north wind, is abducting Orithyia, daughter of the legendary Athenian king Erechteus. You can recognize Boreas on the left from his wings. Orithyia runs off the scene to the right. Meanwhile, Athena stands in the middle (larger, again, because she is the most important figure in this scene), calm and resembling a column, holding her hand up in an attempt to make Boreas stop. Athena is the patron goddess of Athens, so she is trying to protect the daughter of the king. On the back of the vase, friends of Orithyia run to tell Erechtheus what has happened to his daughter.
So the next time you are entering the permanent collection galleries, stop and take a peek at the two ancient Greek hydrias. These 2,500 year-old treasures pack a lot of information!

Clover is a useful cover crop and companion plant that can provide many benefits to your garden or lawn. Knowing the best time to plant clover is key to getting it established and allowing it to thrive. In this article, we'll look at the ideal planting times for clover according to your climate and goals.
What are the Benefits of Clover?
Before getting into specifically when to plant, let's first go over why you would want clover in the first place. Here are some of the top benefits:
- Fixes nitrogen in the soil. The roots of clover form a symbiotic relationship with nitrogen-fixing bacteria, taking nitrogen from the air and converting it into a form that plants can use. This can reduce or eliminate the need for nitrogen fertilizers.
- Weed suppression. Once established, clover forms a dense mat that helps block light from reaching weed seeds and smothers small weed seedlings.
- Attracts pollinators. The nectar-rich flowers of clover attract and provide food for bees, butterflies, and other pollinating insects.
- Erosion control. Clover forms a ground cover that holds soil in place and prevents erosion.
- Tolerates foot traffic. White clover in particular holds up well to foot traffic, making it a good option for lawns, garden paths, and high traffic areas.
Ideal Planting Times for Clover
For most climates, the spring is the best time to plant clover. This gives the clover time to get established before summer heat arrives.
Clover seed germinates best when soil temperatures are between 50-85°F. In northern regions, aim to plant clover 4-6 weeks before the last spring frost date. In warmer southern climates, plant clover in early spring as temperatures begin to warm.
If sowing clover with cool season lawn grasses like fescue, plant in early spring 1-2 months before the last frost. The grass and clover should germinate and establish together.
Planting clover in fall can also be successful in many regions. This allows the clover to take advantage of cool, moist fall conditions ideal for germination.
In northern climates, plant clover in early fall, 6-8 weeks before the first expected frost date. In southern climates with milder winters, plant clover in late fall or early winter. Make sure there is enough time for the clover to become established before cold winter weather arrives.
The benefit of fall planting is the clover will be ready to thrive and fix nitrogen early in the spring. Time fall clover plantings so that the plants have 4-6 weeks to germinate and grow before growth slows for winter.
Tips for Planting Clover
Here are some tips for getting your clover crop off to the right start:
- Prepare soil by removing existing weeds, tilling if needed, and raking smooth. Clover needs direct contact with the soil to sprout.
- Amend soil with compost or fertilizer low in nitrogen. Phosphorus and potassium promote root growth.
- Sow seeds 1/4-1/2 inches deep. Newly seeded clover needs consistent moisture to germinate. Water gently daily if rainfall is lacking.
- If overseeding, use a dethatching rake to disturb the soil surface before broadcasting clover seeds. This improves soil contact.
- Inoculate clover seed with the appropriate rhizobium bacteria for optimum nitrogen fixation.
- Seeding rates vary by clover type. Check suggested rates on the seed package or with your local extension office.
- Keep seedbed consistently moist until clover is 3-4 inches tall and well established.
With proper timing for your climate and good soil preparation, you can expect healthy stands of clover that will thrive and provide abundant benefits to your garden. Clover is one of the easiest and most useful cover crops you can grow, so don't hesitate to add it to your lineup.
Fall vs Spring Planting: Which is Better?
When comparing spring vs fall clover planting, spring planting will lead to faster germination and establishment since temperatures are warming. However, fall planting can work very well in mild climates and ensures plants are ready to thrive early in spring.
Here are some factors to help decide between spring or fall clover planting:
Spring planting pros:
Faster germination with warmer soil temperatures
Clover establishes quickly with summer moisture
Synchronize planting with cool season grasses
Fall planting pros:
Avoids hot summer temperatures
Takes advantage of fall rains for germination
Less weed pressure in fall
Well established before winter dormancy
In most regions, spring planting is preferable for starting new clover stand s. Fall planting works well when filling in thin lawns or gardens that already have some clover established. Overseeding in either spring or fall can be effective.
The Takeaway on Clover Planting
In summary, clover is a versatile cover crop suitable for gardens, lawns, pastures, and fields throughout many climates. For most regions, the ideal time to plant clover is spring, once temperatures have warmed and danger of frost has passed. Well-timed fall planting can also be successful, especially for overseeding existing stands. Prepare soil well, inoculate seed, and keep the seedbed moist for successful clover establishment. With proper planting care, clover will thrive and provide ongoing soil nitrogen along with other benefits.

I'm struggling with my Weather Machine project. It's almost done, but I can't create working button to switch between metric and imperial units. I think it's something about functions scope, because everything works nice separately, but doesn't want to run together.
Here's my Pen: _URL_
each function is described, I believe that issue is between getTemp() function and '#switch' button event handler.
I know the solution will probably be really simple, but I'm still missing it
you were declaring var with strings instead of referencing another variable.
also, there was a problem with var scope.
// calculate adn display right temperature
celsius = Math.floor(temp) + "° C";
fahrenheit = Math.floor( (temp) * 9/5 + 32 ) + "° F";
degrees = celsius
// switch between Celsius and Fahrenheit
(degrees === celsius) ? degrees = fahrenheit : degrees = celsius;
Thank you, now it works fine that was so stupid mistake of me

2.3.1.2 text
text of type DOMString
Represents the text content of the node or the concatenated text representing the node and its descendants.
The text attribute is read/write. When concatenated, the text represents the contents of text or CDATA nodes. All concatenated text nodes are normalized according to xml:space attributes and the value of the preserveWhiteSpace switch. Concatenated CDATA text is not normalized. (Child nodes that contain NODE_COMMENT and NODE_PROCESSING_INSTRUCTION nodes are not concatenated.) The text attribute trims the whitespace on the edges of the result, and "normalizes" \r\n => \n, but otherwise just concatenates text.
Retrieves and sets the string representing the text contents of this node or the concatenated text representing this node and its descendants.
For more precise control over text manipulation in an XML document, use the lower-level nodeValue property, which returns the raw text associated with a NODE_TEXT node.

3.3. Foreign Keys
Recall the weather and cities tables from Chapter 2. Consider the following problem: You want to make sure that no one can insert rows in the weather table that do not have a matching entry in the cities table. This is called maintaining the referential integrity of your data. In simplistic database systems this would be implemented (if at all) by first looking at the cities table to check if a matching record exists, and then inserting or rejecting the new weather records. This approach has a number of problems and is very inconvenient, so PostgreSQL can do this for you.
The new declaration of the tables would look like this:
CREATE TABLE cities (
 city varchar(80) primary key,
 location point
);
CREATE TABLE weather (
 city varchar(80) references cities(city),
 temp_lo int,
 temp_hi int,
 prcp real,
 date date
);
Now try inserting an invalid record:
INSERT INTO weather VALUES ('Berkeley', 45, 53, 0.0, '1994-11-28');
ERROR: insert or update on table "weather" violates foreign key constraint "weather_city_fkey"
DETAIL: Key (city)=(Berkeley) is not present in table "cities".
The behavior of foreign keys can be finely tuned to your application. We will not go beyond this simple example in this tutorial, but just refer you to Chapter 5 for more information. Making correct use of foreign keys will definitely improve the quality of your database applications, so you are strongly encouraged to learn about them.

ElementOperand QML Type
The OPC UA ElementOperand type. More...
Import Statement: import QtOpcUa .
Since: QtOpcUa 5.13
Properties
Detailed Description
The ElementOperand is defined in OPC-UA part 4, 7.4.4.2. It is used to identify another element in the filter by its index (the first element has the index 0).
This is required to create complex filters, for example to reference the two operands of the AND operation in ((Severity > 500) AND (Message == "TestString")). The first step is to create content filter elements for the two conditions (Severity > 500) and (Message == "TestString"). A third content filter element is required to create an AND combination of the two conditions. It consists of the AND operator and two element operands with the indices of the two conditions created before:
import QtOpcUa 5.13 as QtOpcUa
QtOpcUa.EventFilter {
 select : [ ... ]
 where: [
 QtOpcUa.FilterElement {
 operator: QtOpcUa.FilterElement.GreaterThan
 firstOperand: QtOpcUA.SimpleAttributeOperand {
 browsePath: [
 QtOpcUa.NodeId {
 identifier: "Severity"
 ns: "_URL_
 }
 ]
 }
 secondOperand: QtOpcUa.LiteralOperand {
 value: 500
 type: QtOpcUa.Constants.UInt16
 }
 }
 QtOpcUa.FilterElement {
 operator: QtOpcUa.FilterElement.Equals
 firstOperand: QtOpcUA.SimpleAttributeOperand {

Purpose. Whereas many previous studies have identified the association between sustained near work and myopia, few have assessed the influence of concomitant levels of cognitive effort. This study investigates the effect of cognitive effort on near-work induced transient myopia (NITM). Methods. Subjects comprised of six early onset myopes (EOM; mean age 23.7 yrs; mean onset 10.8 yrs), six late-onset myopes (LOM; mean age 23.2 yrs; mean onset 20.0 yrs) and six emmetropes (EMM; mean age 23.8 yrs). Dynamic, monocular, ocular accommodation was measured with the Shin-Nippon SRW-5000 autorefractor. Subjects engaged passively or actively in a 5 minute arithmetic sum checking task presented monocularly on an LCD monitor via a Badal optical system. In all conditions the task was initially located at near (4.50 D) and immediately following the task instantaneously changed to far (0.00 D) for a further 5 minutes. The combinations of active (A) and passive (P) cognition were randomly allocated as P:P; A:P; A:A; P:A. Results. For the initial near task, LOMs were shown to have a significantly less accurate accommodative response than either EOMs or EMMs (p < 0.001). For the far task, post hoc analyses for refraction identified EOMs as demonstrating significant NITM compared to LOMs (p < 0.05), who in turn showed greater NITM than EMMs (p < 0.001). The data show that for EOMs the level of cognitive activity operating during the near and far tasks determines the persistence of NITM; persistence being maximal when active cognition at near is followed by passive cognition at far. Conclusions. Compared with EMMs, EOMs and LOMs are particularly susceptible to NITM such that sustained near vision reduces subsequent accommodative accuracy for far vision. It is speculated that the marked NITM found in EOM may be a consequence of the crystalline lens thinning shown to be a developmental feature of EOM. Whereas the role of small amounts of retinal defocus in myopigenesis remains equivocal, the results show that account needs to be taken of cognitive demand in assessing phenomena such as NITM.

The main aim of the study is to analyze the impact of national culture on human resource management. When considered in a cross-cultural context, the human resource strategies vary a lot. Hofstede's work is most prevalent in cross-cultural management studies. So his dimensions in national culture are used in the analysis of India and US. This study defines how pay, motivation and the reward system are influenced by the culture. The cross-cultural merits and demerits are mentioned in this report. This report also concentrates on national culture influences on human resource management. This report shows that the national culture influence on human resource management practices. Therefore, this report says that the human resource practices are bounded by culture, values of the society.
Human Resource Management (HRM) is highly influenced by culture. Many aspects of HRM are different in different countries. When studying about the impact of culture on HRM it is necessary to see what is meant by culture. Culture is a complicated concept among the researchers. In anthropological and sociological terms, culture refers to the values and attributes of the community the people belong. "Hofstede defines culture as the collective programming of the mind based on a broad tendency to prefer certain states of affairs over others" (Tayeb 2008). Tayeb defined culture as historically evolved values, attributes and meaning which are learned and shared by the members of the community and which influence their way of life. All researchers give different meanings to culture. It is different between nations. HRM can be influenced by culture. Some HRM functions like recruitment, pay, reward system, training, and development are underpinned by associated culture values.
Personnel management is a traditional administrative function. They are maintenance oriented. These are usually performed by the personnel department in an organization. They will react, respond only when problems arise. The main motivators of PM are compensations, rewards, job simplification and so on. PM is criticized in many ways. Employees are viewed as 'economic animal' who can be motivated through the manipulation of reward system. The power is playing in many organizations.the managers want the employees to do what they want. Attention is little paid to the views of the employee. (Tayeb 2008)
HRM is an American invention in early 1980s. it was practiced in some companies and the positive record adapted it many companies. Then it came to European countries. The effective HRM leads to higher productivity and higher performance. HRM also deals with personnel functions buts they are planned and implemented with regard to the companies' strategies. (Tayeb 2008)
According to Porter, The strategic role of HRM is to support activities of the organization. HRM is different from personnel management in three ways. (Tayeb 2008)
Firstly, Personnel management focuses on the management and the sub-ordinates and HRM focus on the entire management team.
Secondly, the line managers have the main role in HRM and to achieve profit by coordinating resources. But this is not in case for the personnel management.
Thirdly, the aspect of the HRM is the management of organizational culture and the personnel management has no role in this.
In 1980's Hofstede found the five dimensions of national culture that can be used to illustrate the different values in different native cultures of different countries. These dimensions can be used to illustrate how people in a different culture act and how they behave in work related factors.
These dimensions are power distance, uncertainty avoidance, individualism/collectivism, and masculinity/femininity.
Figure 1: Hofstede's Model of Cultural Differences
Hofstede's study has been criticized in many ways but it is very useful to know the cross-cultural framework. It is very helpful for someone who is entering into the new business or employment. All should be aware of the different cultural differences. Each country has its own culture and this cultural difference can influence workplace value and business communication.
Power distance:
If power distance score is higher, that means there are unfair relationships between the superiors and the subordinates. It also shows the inequalities of power and wealth are allowed in the societies. Power distance is high in countries like India and France. Their employees have to show respect to the higher authorities. The decision making is centralized. That means managers will not include the employees while taking decisions about their appraisals. In countries like Australia and Israel, there is a low inequality culture. Employees feel free to consult with the managers in whatever situations they are. They do not feel it as a disrespectful manner. They have the flexibility in their work. Here decision making takes place in the presence of the employees. (Henderson 2008).
India indicates a high power-distance score that shows the high level of inequality of power and wealth within the society. The people accept this as a cultural norm. The score of India is 77 and the world average is 56.5. US indicates a low power distance of 40 that shows they have greater equality of power. (
Uncertainty Avoidance [UA]:
The extent to which how easily the culture corporate with the changes. If UA is high, it creates a rule-oriented society. If UA is low the society is less rule-oriented and they are highly tolerance to variety of opinions and also they take greater risk. France has high uncertainty avoidance score, when compared with the lower U.S. score. Americans do not displace or dismiss any employee whose work is unsatisfactory; they consider it as a gain in efficiency. But the French need for continuing relationships with long-time members of the company, whose trusted presence reduces uncertainty. Countries like Japan and Greece have high UA. The employees in companies in these countries are attracted to long term commitment. Companies in countries like Denmark Hong Kong, the people are not able to corporate with the changes very easily and they find things in a sensible way rather than following theories. They will try to find out the need for change and work accordingly. People do not want to work in a stable work atmosphere. (Henderson 2008).
India is having a low ranking in UA. The culture is more open to unstructured ideas and situations. The dimension score is 40 when compared to world average which has 65. This dimension score is high for US. They have 46. That means they have less rules and greater level of tolerance. (
Individualism / Collectivism:
It is the extent to which the culture encourages the individual. Countries like USA, UK they have individualist culture. They give importance to individual achievement. Here the aim is to be a good leader. People work only the normal hours and they want to get paid if they work overtime. They do not consider the relation to overlap with the private relation. Where individualism is high people are expected to take care of themselves and their family. Countries like Iran and Peru they have collectivist cultures. The entire organization works like one family. They support each other. Their aim is to be a good member of the organization. They

1. Introduction
Laryngeal cancer (LC) is one of the most frequently diagnosed head and neck malignancies, causing 83 thousand deaths worldwide each year. In 2012, the highest age-standardized incidence rate of LC in Asia area was 6.3 per 100 thousand persons, respectively [1] . Currently, surgical operation is the most effective treatment. One tenth of perilaryngeal patients undergo partial or total laryngectomy [2] . A high incidence of postoperative complications occurred after partial or total laryngectomy [3] . Tracheostomal after laryngectomy causes the respiratory changing: respiratory mucosal warming, humidifying, filtering loss. And the risk of post-operative infection is usually related to the peri-operative exposure of the wound to commensal bacteria colonizing mucous membranes and skin [4] . Above all increase the rate of pulmonary infection [5] . It was reported that the incidence of pulmonary infection after laryngectomy was 1.4%, Pseudomonas aeruginosa, Escherichia coli, Streptococcus pneumonia are the frequent pathogenic bacteria of pneumonia, of which Pseudomonas aeruginosa is the major pathogens [6] [7] . Therefore, all LC patients with postoperative tracheostomy would receive antibiotic prophylaxis with cephalosporin, aminoglycoside and metronidazole [8] . With the clinical abuse of the broad-spectrum antibiotics, the drug resistances are increased in Pseudomonas aeruginosa, and the incidence of Pseudomonas aeruginosa pneumonia is increasing these years. Elderly patients with pneumonia in early stage lack typical respiratory symptoms, 30% of who only have the symptom of acute disturbance of consciousness, shortness of breath and accelerated heart rate [9] . Above all, it will lead to the delay of treatment and care. Nurses play a critical role in patients' care throughout the pre- and postoperative period with special nursing for their safe transition back to society [10] . In this study, our purpose was to present our special nursing care of the laryngectomy patient secondary to Pseudomonas aeruginosa pneumonia with conscious disturbance for ENT nurses as a reference.
2. Clinical Data
A 71-year-old man had presented hoarseness during the past 1 year, visiting hospital in August, 2017. Pathological diagnosis was glottic cancer (T1N0M0). Cricohyoidoepiglottopexy (CHEP) was performed under generalanesthesia with perfect preoperative preparation. Fervescence occurred at the third day postoperatively, the oral temperature increasing from 38˚C to 39.5˚C. Then conscious disturbance occurred at the 5th day; the Glasgow Coma Scale (GCS) scores were 12; be a purulent yellow-green expectoration; the skull CT scanning had no abnormality, but thorax CT diagnosed pulmonary inflammation and little pleural effusion; blood pictures were abnormal (blood calcium 1.6 mmol/L, blood kalium 3.0 mmol/L, blood sodium 122 mmol/L). Phlegm cultivation before use medicine was chosen firstly, then adjust antibiotic based on phlegm cultivation results (Pseudomonas aeruginosa and klebsiella species infection) and drug sensitivity test results (Amikacin). Therapeutic Methods were anti-inflammatory, temperature decreasing, eliminating phlegm, rehydration, monitoring of blood routine examination, hepatic and renal functions, electrolytes, blood glucose and others. The recovery of consciousness was at the 9th day postoperatively, with the GCS score 15. The patient tried to take food, oral temperature recovery to normal, but occurred irritating cough at the 10th day. Classifications of levels of bedside water-swallowing test (WST) are level 1 - 5. The result of 30 ml bedside water-swallowing test was level 4. Then, the swallow function returned to level 3 in 17th days, the vital signs were all stable, thorax CT and phlegm cultivation results returned normal. The patient discharged hospital with metal tracheal cannula. Postoperative special nursing care of the patient is in Table 1.
Table 1. Postoperative special nursing care of the patient.
3. Nursing Focus
3.1. The Nursing of Pseudomonas aeruginosa Pneumonia
The symptom of mucous membrane dryness, weakness of cough occurred in the early postoperative period. Pseudomonas aeruginosa pneumonia caused fever, delirium, purulent yellow-green expectoration, oxygen saturation down. Besides humid sputum suction, the pertinence measure to the symptom existed is: 1) Monitoring of vital signs was immediately carried out, blood pressure (108/55 mmHg), heart rate (>128 beats/min), the blood oxygen saturation (93%). Mask oxygen-inspiration (6 - 8 L/min) with tracheotomy tubes and intravenous fluids supplement had kept vital signs normal. 2) In early postoperative stage, the great dose of cefuroxime antibiotics was used to prevent the infection of Haemophilus influenzae and Meningococcus, invalid therapy for Pseudomonas aeruginosa and Staphylococcus aureus infection. Basis for phlegm cultivation results (Pseudomonas aeruginosa and klebsiella species infection) and drug sensitivity test results, the optimal dose of Amikacin and Imipenem-Cilastain was used. Meanwhile, the adverse drug reaction (ADR) was being monitored for 6 days continuously, like hepatic and renal function, hematuria and proteinuria, auditory function. 3) The color, characteristics, quantity of phlegm were closely observed and recorded every day. Once the infection of cervical incision, oral and nasal mucosa occurred, the specimens were taken to test pathogenic bacteria. 4) Moist skin were easy to be damaged with heavy perspiration caused by the fever (38˚C - 39.5˚C), especially the cervical pressure bandaging skin, the nasal entrance skin of nasogastric tube, electrode slices paste skin. Observation of skin humidity and skin temperature per hour can avoid complications. According to the grade of sputum density (level-1 mucoid, level-2 mucopurulent, level-3 purulent), the characteristics of sputum were changed from purulent (level 3) to mucoid (level 1) and no other complications occurred.
3.2. The Nursing of Conscious Disturbance
Hypoimmunity after surgical injury may be a main cause of bacterial infection in the elderly patients. And the bacterial toxins and imbalance of water-electrolyte were the main factors of conscious disturbance. The change tendency of postoperative GCS scores was as follows (Figure 1). Sudden confusion (GCS score 12) appeared in the postoperative 5th day. GCS assessed 3 parts: best eye opening response (To speech-call the patient's name); best verbal response (Confused about time and place orientation); motor response (Localise to pain). Pupil sizes were normal, but the pupillary light reflex delayed. The skull CT scanning had no abnormality. Considering that conscious disturbance might be caused by Pseudomonas aeruginosa pneumonia. The level of consciousness could reflect the severity of pneumonia in some degree [11] . Therefore, the assessment of consciousness level played an important role for mastering the progress of disease. Communication with the family members was helpful for disease evaluation. During continued treatment, GCS was 13 scores, with best eye opening response (Spontaneous-observed before approaching the patient); best verbal response (confused about time and place orientation); motor response (Localise to pain) in the 7th day. Spontaneous motor activity like hand gestures increased and sleep time reduced. The pupillary light reflex recovered in the normal subject, GCS score 14 appearing to be confused about place orientation in the 8th day, encouraging the patient to communicate with written forms. The time of consciousness recovery was in the 9th day and GCS score 15 was assessed to be normal.

Title: Effects of dietary histidine and plant lipids on the Atlantic salmon (Salmo salar) health status following transfer to seawater
Name: Inês Carvalho
With the aquaculture expansion, there is great urgency in reducing the industry's dependence on finite-marine ingredients, such as fish oil. However, plant lipid-based diets might markedly deviate from fish natural feeding habits and negatively impact their health. In the particular case of Atlantic salmon (Salmo salar), this issue acquires major relevance during the seawater transfer, a challenging production moment often associated with great losses. To improve the overall fish health, supplementing diets with immuno-modulators, such as certain amino acids, is becoming a common approach.
The aim of this study was to investigate whether dietary lipid source and histidine supplementation could influence the non-specific immune response and antioxidant system in Atlantic salmon after seawater transfer.

Problems and Prospects of Vegetables Gardening In Machchhegaun: A Case Study
Keywords:Vegetable gardening, landholding, production, income, crops, land
Agriculture production contributes 32.60 percent of GDP in which vegetable contribution is 9.7 percent in Nepalese economy. This article triesto find out the conditions and state of vegetable production and productivity, including problems and prospects of Machchhegaun, one of the villages of ward no. 7 of Kirtipur Municipality. This village is good for vegetable production due to suitable climate, good topography, fertile land and market accessibility. Of the total arable land, only 6.9 percent is for vegetable production. However, its yield is higher as compared to other staple food crops like paddy, maize and wheat. This apparently shows that there is higher potentiality of vegetable gardening which can be helpful to fulfill the requirements of vegetables to the growing population of Kirtipur Municipality. However the farmers are facing many problems like that of lacking technical knowledge, lack of improved seeds, fertilizer, agriculture equipments and financials supports.

How to fix different sampling rates in a dataset with Nkululeko
With nkululeko since version 0.62.0 you can automatically adjust the sampling rate to the standard of 16 kHz, which is required by most models that might need to process your data.
A special module can be configured in the configuration file like this:
[RESAMPLE]
# which of the data splits to re-sample: train, test or all (both)
sample_selection = all
replace = True
target = data_resampled.csv
and then you call it like this
python -m nkululeko.resample --config my_config.ini
WARNING: if replace = True, this changes (overwrites) ALL files in the splits, directly on your hard disk. Make sure to make a safety copy of your database before, in case the results are undesired, or you still need the data in other sample rates.
The default value though, is replace = False . Then, the target value will be used as filename for the new dataframe with filenames that indicate that the sampling rate has been changed.
As stated above, only files in the test and train splits are affected. This means that you can use all filtering, e.g. limit samples per speaker to 20 samples to pre-select samples.
Nkululeko: how to predict labels for your data from existing models and check them
With nkululeko since version 0.58.0, you can predict labels automatically for a given database, and then perhaps use these predictions to check on bias within your data.
One example:
You have a database labeled with smokers/non-smokers. You evaluate a machine learning model, check on the features and find to your astonishment, that the mean pitch is the most important feature to distinguish between smokers and non-smokers, with a very high accuracy.
You suspect foul-play and auto-label the data with a public model predicting biological sex (called gender in Nkululeko).
After a data exploration you see that most of the smokers are female and most of the non-smokers are male.
The machine learning model detected biological sex and not smoking behaviour.
How do you do this?
Firstly, you need to predict labels. In a configuration file, state the annotations you'd like to be added to your data like this:
[DATA]
databases = ['mydata']
mydata = ... # location of the data
mydata.split_strategy = random # not important for this
...
[PREDICT]
# the label names that should be predicted: possible are: 'gender', 'age', 'snr', 'valence', 'arousal', 'dominance', 'pesq', 'mos'
targets = ['gender']
# the split selection, use "all" for all samples in the database
sample_selection = all
You can then call the predict module with python:
python -m nkululeko.predict --config my_config.ini
The resulting new database file in CSV format will appear in the experiment folder.
The newly predicted values will be named with a trailing _pred, e.g. "gender_pred" for "gender"
You can than configure the explore module to visualize the the correlation between the new labels and the original target:
[DATA]
databases = ['predicted']
predicted = ./my_exp/mydata_predicted.csv
predicted.type = csv
predicted.absolute_path = True
predicted.split_strategy = random
...
[EXPL]
# which labels to investigate in context with target label
value_counts = [['gender_pred']]
# the split selection
sample_selection = all
and then call the explore module:
python -m nkululeko.explore --config my_config.ini
The resulting visualizations are in the image folder of the experiment folder.
Here is an example of the correlation between emotion and estimated PESQ (Perceptual Evaluation of Speech Quality)
The effect size is stated as Cohen's d, for categories that have the largest value, in this case the difference of estimated speech quality is largest between the categories neutral and angry.

Area Protection and Management
Certain areas of Antarctica are set aside under Annex V of the Protocol on Environmental Protection to the Antarctic Treaty as protected areas to preserve their special values. There are two forms of protection:
- Antarctic Specially Protected Areas (ASPA) are designed to protect outstanding environmental, scientific, historic, aesthetic or wilderness values, a combination of these values, or ongoing or planned scientific research. A permit is required to enter an ASPA
- Antarctic Specially Managed Areas (ASMA) are aimed at assisting in the planning and co-ordination of activities, including improving co-operation between Parties and minimising environmental impacts. A permit is not required to enter an ASMA.
The Antarctic Treaty System also provides for the listing of Historic Sites and Monuments, to preserve and protect them from damage and destruction.
Antarctica New Zealand requires that the personnel it supports:
- are aware of the location of protected areas in locations they intend to visit;
- obtain permits for entry to any protected area before leaving for Antarctica and carry them in the field;
- follow the requirements set out in the management plan for any ASPA or ASMA they enter;
- follow the Antarctic Heritage Trust's Code of Conduct when visiting any historic site.
An accurate record is made of activities in ASPAs and ASMAs. Reports on activities are made to the Ministry of Foreign Affairs and Trade and to the Antarctic Treaty nations.


enables us to construct the following composite "connecting maps"
π n(X s)π n(Y s)π n1(X s+1). \pi_n(X_s) \to \pi_n(Y_s) \to \pi_{n-1}(X_{s+1}).
relating the homotopy groups of the fibers X sX_s. For reasons that will become clear later, we'll call these maps d 2d^2 (note that this does not mean the square of a map dd; the superscript 22 is just an index). The first interesting thing we notice about them is that they satisfy d 2d 2=0d^2 \circ d^2 = 0, since in the composite
π n(X s)π n(Y s)π n1(X s+1)π n1(Y s+1)π n2(X s+2) \pi_n(X_s) \to \pi_n(Y_s) \to \pi_{n-1}(X_{s+1}) \to \pi_{n-1}(Y_{s+1}) \to \pi_{n-2}(X_{s+2})
the middle two maps are adjacent in a LES, hence compose to 00. Thus, for every value of n+sn+s, we have a chain complex
d 2π n(X s)d 2π n1(X s+1)d 2π n2(X s+2)d 2. \cdots \xrightarrow{d^2} \pi_n(X_s) \xrightarrow{d^2} \pi_{n-1}(X_{s+1}) \xrightarrow{d^2} \pi_{n-2}(X_{s+2}) \xrightarrow{d^2} \cdots.
Of course, if we're experienced homological-algebraists, the first thing that we want to do with a chain complex is take its homology, but let's step back a second to make sure that that's a sensible thing to do.
A cycle in this chain complex is an element xπ n(X s)x\in \pi_n(X_s) that becomes zero in π n1(X s+1)\pi_{n-1}(X_{s+1}). This means that when we map xx into π n(Y s)\pi_n(Y_s), it lands in the kernel of π n(Y s)π n1(X s+1)\pi_n(Y_s) \to \pi_{n-1}(X_{s+1}). But since the sequence
π n(X s+1)π n(Y s+1)π n(Y s)π n1(X s+1) \cdots \to \pi_n(X_{s+1}) \to \pi_n(Y_{s+1}) \to \pi_n(Y_s) \to \pi_{n-1}(X_{s+1}) \to \cdots
is exact, that means exactly that the image of xx in π n(Y s)\pi_n(Y_s) lies in the image of π n(Y s+1)\pi_n(Y_{s+1}). In other words, an element xπ n(X s)x\in \pi_n(X_s) automatically gives us an element of π n(Y s)\pi_n(Y_s), while d 2(x)d^2(x) is precisely the "obstruction" to lifting that to an element of π n(Y s+1)\pi_n(Y_{s+1}). This naturally seems like the "first step" towards lifting it to an element of π n(Y)\pi_n(Y), which is what we're really interested in.
Similarly, a boundary in this chain complex is an element of π n(X s)\pi_n(X_s) that's in the image of π n+1(X s1)\pi_{n+1}(X_{s-1}), and hence in particular in the image of π n+1(Y s1)\pi_{n+1}(Y_{s-1}). But since the sequence
π n+1(Y s1)π n(X s)π n(Y s)π n(Y s1) \cdots \to \pi_{n+1}(Y_{s-1}) \to \pi_n(X_{s}) \to \pi_n(Y_{s}) \to \pi_n(Y_{s-1}) \to \cdots
is exact, any such element must map to zero in π n(Y s)\pi_n(Y_{s}), and hence also lift to zero in π n(Y s+1)\pi_n(Y_{s+1}). So the homology at π n(X s)\pi_n(X_s) (the group of cycles modulo the group of boundaries) is indeed a reasonable "second approximation" to "what we can learn about π n(Y)\pi_n(Y) from π n(X s)\pi_n(X_s)".
For a "third approximation", we can more or less repeat the process. Given something in this homology "H n,s(π *(X *))H_{n,s}(\pi_\ast(X_\ast))", we can lift it to π n(Y s+1)\pi_n(Y_{s+1}), then map it into π n1(X s+2)\pi_{n-1}(X_{s+2}). The result is not well-defined because the lift is not well-defined, but its indeterminacy is precisely that of the lift, which by exactness is just an element of π n(X s+1)\pi_n(X_{s+1}). Thus, we do have a well-defined element of the quotient of π n1(X s+2)\pi_{n-1}(X_{s+2}) by the image of d 2d^2, which happens to also lie in the kernel of d 2d^2, and hence a map d 3:H n,s(π *(X *))H n1,s+2(π *(X *))d^3 : H_{n,s}(\pi_\ast(X_\ast)) \to H_{n-1,s+2}(\pi_\ast(X_\ast)). I'll leave it to you to check that these maps make H n,s(π *(X *))H_{n,s}(\pi_\ast(X_\ast)) into another chain complex, and that elements of its homology can be lifted to π n(Y s+2)\pi_n(Y_{s+2}).
In order to describe these higher approximations uniformly, let's introduce a bit more terminology. Recall that if GG is an abelian group, then a GG-graded abelian group is just a family (A g) gG(A_g)_{g\in G} of abelian groups indexed by the underlying set of GG. If AA and BB are GG-graded abelian groups and hGh\in G, then a degree-hh map f:ABf:A\to B consists of maps f g:A gB g+hf_g : A_g \to B_{g+h} for all gg. The composite of a degree-h 1h_1 map with a degree-h 2h_2 map is a degree-(h 1+h 2)(h_1+h_2) map. For example, an unbounded chain complex may be defined as a \mathbb{Z}-graded abelian group equipped with a degree-1 (or degree-(1)(-1)) endomap dd such that dd=0d \circ d = 0 (an equality of maps of degree 2 or (2)(-2)).
Now, the groups π n(X s)\pi_n(X_s) and π n(Y s)\pi_n(Y_s) can be assembled into a pair of (×)(\mathbb{Z}\times \mathbb{Z})-graded abelian groups DD and EE, and three maps between them ii, jj, and

Pilgrim souvenir ("blessing") of St Menas in the shape of a circular flask (neck and handles are missing). There are relief images of St Menas flanked by prostrated camels on both sides of the flask. Border is composed by a circular wreath surrounded by inscription: ΕΥΛΟΓΙΑ ΤΟΥ ΚΑΛΛΙΝΙΚΟΥ ΑΓΙΟΥ ΜΗΝΑ.
Pilgrim eulogiae (literally "blessings") were little souvenirs sanctified by contact with the divine, given or sold to pilgrims to take home as mementoes of their journey. But eulogiae did more than induce a traveler's memory: by virtue of the concentrated holiness they contained, eulogiae could miraculously heal the sick or calm a stormy sea. Eulogiae took the shape of pressed-earth seals or tokens, lamps, flasks for oil or water (ampullae), or even ribbons and pieces of cloth (brandaria) that had touched a saint or holy place. Many eulogiae were a sensory multiplex of material, inscription, and image. In addition to fostering or even creating memories of the locus sanctus (holy place) from which they came, eulogiae ensured that the salvific, curative power of the saints was accessible no matter the distance from their shrines.

John Sholto Douglas Queensberry, 8th marquess of
Queensberry, John Sholto Douglas, 8th marquess of, 1844–1900, British nobleman, originator of the code of rules that governs modern boxing. He served in the British army and navy and later was a member of (1872–80) the House of Lords as representative peer from Scotland. He is famous for drafting (1865), with the aid of John G. Chambers, the Queensberry rules for the sport of boxing. This code of rules, superseding the London prize-ring rules that had been introduced (1743) by Jack Broughton, contained the basic provisions that govern boxing today. The rules were gradually adopted in both Britain and the United States and by 1889 they were standardized. In 1895, objecting to the liaison between his son, Lord Alfred Douglas, and Oscar Wilde, Queensberry left an insulting letter to Wilde in a public place and was sued for libel by the writer. In this libel suit, which Wilde dropped, information was brought to light that led to the conviction of Wilde for immoral conduct.

Incriminating Evidence On Cell Phones
March 2021
Cell phones are very useful – for telephone calls, text messaging and photographing. However, the information contained on the cell phone can be incriminating.
An abandoned cell phone
In a recent Court of Appeal case, the police were pursuing a young male driver who was driving at 160 kilometres per hour. During the chase, the driver drove off the main road into a forestry track and crashed his car into the tree. He fled the car and ran into the forest to avoid the police. When the police arrived at this car, a female passenger who was still in the car refused to identify the driver but upon being question by the police pointed at the cell phone at the passenger's footwell and confirmed that it belonged to the driver.
A Constable picked up the phone, swiped the screen and found it unlocked. The Constable came across a text message thread between the driver and another man (Mr R) including a photograph of a truck which was stolen in the area a few days ago.
A prosecution
The police used the evidence obtained from the cell phone to obtain a production order against Mr R and found the truck resulting in the arrest of Mr R, who was charged with receiving the truck stolen from commercial premises in Kawerau. He was found guilty in the District Court but appealed that conviction.
A lawful search of property
Mr R applied to the Court of Appeal to have the evidence obtained against him by the Constable on the cell phone deemed unlawful. The Court of Appeal ruled that police are entitled to lawfully search property that has been abandoned. Search and surveillance laws against unjustified intrusions of privacy do not apply to abandoned property. In this case, the cell phone had been abandoned and the police were lawfully entitled to search it and that is how they came across Mr R and the stolen truck. The Court of Appeal concluded that the evidence obtained from the cell phone could be used against Mr R. The appeal was dismissed.
This case highlights how cell phone evidence can be used by both the prosecution and the defence to their advantage. Whilst cell phone evidence will not be determinative of a case, it might assist in corroborate evidence one way or another. The convenience of cell phones is unquestionable. But you need to be aware that in certain circumstances the information contained on your cell phone can be used in evidence against you.

The Articulated Total Body Model (ATB) is used for predicting gross segmented body response in various dynamic environments. The ATB computer program, originally written by the Department of Transportation as a Crash Victim Simulation (CVS) program, was later modified by the Calspan Corporation and More recently by the Armstrong Aerospace Medical Research Laboratory (AAMRL) to allow for aerodynamic force applications, harness belt capabilities and hyper-ellipsoidal graphical display of the modeled segments. The ATB model has been successfully used to investigate gross human body responses to bodies placed in such complex dynamic environments as high-speed aircraft ejection. This ATB model is quite versatile due to the variety of inputs it can handle. Because of this versatility, a wide range of physical systems may be simulated.
In this work, the ATB computer program has been modified for use on the Apollo workstation and utilized to predict limb and joint limitations a modeled human arm for the purpose of creating more effective rehabilitation schedules. A patient's left shoulder, left-upper and left-lower arm have been modeled for a case study. The required information consists of segment physical dimensions, weight.center of gravity and maximum forces and torques obtainable from various body muscles. From this information, forces a graphical display of desired segment positions, and numerical approximations of forces, torques, positions, velocities, and accelerations of any desired point of the modeled segment. A comparison of this numerical output found from the ATB will be made with actual patient response, further input will be created tracking the patient's rehabilitation progress. A mathematical model of this will be incorporated into the ATB for the purpose of predicting future patient responses and a predicted schedule for disabled patient rehabilitation.An accurate numerical and visual prediction of patient responses and limitations would be very beneficial in the creation of rehabilitation schedules. For such a service to be obtainable in a hospital environment, the ATB must be executable on a personal computing level. The Apollo workstation was selected for this project due to its relative mobility and availability. Many similar computing systems could be used where the criteria of mobility, large memory capabilities and superior graphics are obtainable. These criteria must be met so that the ATB could eventually be used by physicians in a clinic or office environment.
