1. Influence of filtering wind speed The wind speed increases the resistance and the wind speed decreases the resistance. For large particles dominated by inertial motion, the wind speed is increased, the inertia of the particulate matter is increased, and the possibility of hitting an obstacle is increased, so the filtration efficiency is improved. However, the inertia is large, and the rebounding force of the obstacle on the particulate matter is also increased. If the van der Waals force cannot overcome the rebounding force, the particulate matter will run away. Therefore, sometimes the wind speed is increased, and the filtering efficiency of the filter on the large particulate matter is lowered.
For small particles mainly composed of diffusion movement, the filtration efficiency depends on the residence time of the particles in the filter medium, the residence time is shortened (increasing the wind speed), the probability of the particles hitting the obstacle is reduced, and the filtration efficiency is lower. If the material is electrostatically charged, the filtration efficiency depends on the residence time of the gas stream in the material. The lower the filtration wind speed, the higher the filtration efficiency, both for large and small particles.
Electrostatic materials are very sensitive to the filtered wind speed. For example, at a wind speed of 1 cm/s, the transmittance of 0.3 μm dust is 0.01% (filtration efficiency is 99.99%), and when the filtration wind speed is increased to 5.3 cm/s, the measured transmittance is 1.5% (filtering) The efficiency is only 98.5%), and the transmission rate is two orders of magnitude.
2, the impact of humidity Under normal circumstances, changing the humidity will not affect the efficiency and resistance of the filter. However, when the air humidity is high, the filter medium may condense, and the surface of the contact between the particles and the obstacle has a water film. The contact surface between the two is large, the adhesion is also large, and the large particles are no longer so easy to rebound, so The filtration efficiency of large particles may be improved.
In reality, if the water is wet to the filter, the performance of the filter may undergo various unpredictable changes. For example, for filter paper made from vegetable fiber, if the paper is poor in water resistance, water makes the paper soft, the fiber is compressed, and the resistance of the filter increases rapidly until the filter is blocked. For another example, the high-efficiency filter carries water, and the dust is transported by water to the leeward side of the material. After drying, the filter becomes a dust collector.

The Hyde-Macraes shear zone in Otago: A result of continental extension or shortening? A kinematic analysis of the Footwall Fault
Degree GrantorUniversity of Canterbury
Degree NameMaster of Science
Mineralised shear zones in Otago are often truncated by regional low-angle faults, which juxtapose schist of different metamorphic grade. The Footwall Fault and the Hyde-Macraes Shear Zone are one example for this kind of tectonic setting, and are the subject to this study. Although, the mechanisms for the development of the mineralised thrust-origin shear zones are well studied, the relationship to the truncating faults is still poorly understood. Currently, the truncating low-angle faults are assumed to be related to crustal extension, starting in the early Cretaceous after the schist passed the ductile-brittle transition. This study presents new kinematic data for the Footwall Fault, suggesting development of normal sense movement under ductile conditions due to an abundant shear band cleavage in the footwall, which dynamically recrystallises quartz grains. However, brittle high-angle normal faults truncating these shear bands indicate either reactivation of normal sense movement after passing the ductile-brittle transition or continuous normal sense movement during the transition. Furthermore, this study presents a model, which suggests a regional scale rolling hinge development, consisting of an array of individual low-angle normal faults along the boundary of the textural zone change from TZ IV to TZIII, and strike-parallel high-angle faults at the NE margin of the Otago schist.

By default, the OnSign TV players are designed to always be connected, so whenever there is any content update, all connected players will immediately synchronize and download the updated content.
The player total bandwidth consumption varies based on five main factors:
- Player Control channel - This is the data sent back and forth to the server, so the player can check for content updates and also report its basic status.
- Player Statistics - This is the data sent to the server containing player resource usage such as CPU, memory, disk usage, among others, and campaign/media playback report.
- Player Media Download - This is a direct result of all media that needs to be downloaded to by the player.
- Live Content - This category includes web pages, streaming content (like youtube)
- Apps Dynamic DataApps will require the download of dynamic content to be presented on screens e.g.: weather info, currency info, etc.
To illustrate some practical examples, here are some scenarios with the average expected data consumption:
Case 1. A player configured to :
- resent one campaign every 15 seconds (it doesn't matter if it is the same campaign or different campaigns)
- Content Interval configured for Realtime
- Internet Data Saving Mode Disabled (this means the player will report every content playback)
This player will consume about 150Mb/month.
Case 2. Having the scenario above but with campaigns presented every 10 seconds will increase the total bandwidth consumption.
Case 3. If you publish a media with 100Gb.
- The player will download 100Gb + some data for the control channel.

Hydroxyapatite (HA) is the main inorganic component of bone tissue. To form composite scaffolds with properties identical to native tissue, it is necessary to know how the shape of the HA particles influence on the cell properties. In this study we investigated the effect of the HA particles shape on the actin cytoskeleton organization (fluorescence microscopy) and the viability of bone marrow mesenchymal stromal cells (MTT test). After 5 days of cultivation in the presence of spherical particles, a greater number of viable cells where observed than the number of viable cells when cultured in the presence of needle-like particles. It is suggested that such dependence is due to a higher sorption capacity of proteins by the spherical particles surface having a large specific surface in comparison with the specific surface of needle-shaped particles.

Before starting the collection of eye tracking and other biometric measures simultaneously, also known as co-registration, it is necessary to ensure that the setup will allow the synchronization of the data streams for later analysis. There are two main types of co-registration setups. The first type uses only one software to record all data steams simultaneously. With this setup, the software ensures the synchronization of data streams and therefore the user does not need to take care of it. The possibility of using this type of setup will be mainly determined by the availability of a co-registration software to be compatible with the biometric and eye tracking systems that are going to be used. In the second type of setup there is one dedicated recording software for eye tracking data and a different one for the other biometric data. Since the recordings are done independently and usually with different computers, we need a method to ensure that the recordings will be accurately synchronized in time. In this article, we are going to focus on this second type of setup and the main method for ensuring a good timing synchronization between biometrics data: shared events.
Shared events are triggers or events that were produced and registered, theoretically, at the same time by your eye tracking system and biometric system. These events will be used as known common points in time between your data streams and will allow their synchronization and analysis after the recording.
Timing accuracy of shared events
What we mean by timing accuracy of the events is the ability of the setup to send and receive a shared event as close in time as possible in the eye tracking and the other biometric data streams. The timing accuracy needed will depend on your intended application and what biometric data you are recording together with eye tracking data. For instance, in the case of EEG, the timing accuracy to timestamp common events should be as high as possible, in the order of one to few milliseconds. This is mainly due to the high temporal resolution of EEG (brain responses are measured with millisecond accuracy). Eye movements, usually categorized as artifacts in the EEG data, are also measured with millisecond temporal resolution. It is important to be able to align the eye tracking data and EEG data with high timing accuracy, so that the eye movements registered in the EEG and eye tracking data are perfectly aligned and the results derived from the synchronized data are correct. On the other hand, if we want to co-register Galvanic Skin Response (GSR) together with eye tracking, the timing accuracy of the shared events is not as crucial as in the case of EEG, mostly because of the high latency of the skin conductance response to an event (1 to 4 seconds).
The timing accuracy of the events highly depends on the capability of your setup to send and timestamp them in both data streams with high timing accuracy. Tobii Pro recommends that you always check the event timing accuracy of the method you choose to send and timestamp your shared events. For example, by making a co-registration recording where you send events to all data streams at known intervals and then check the time distribution of those events. If you are interested in co-registering EEG, you can also use tools like the EYE-EEG plugin (EEGLAB), which will output information about the synchronization quality of your co-registration recording.
Sender is the method you use to send the events to your data streams. The most common options are:
Receiver is the device that receives and timestamps the events in each data stream. There will be one receiver for eye tracking and one for the other biometric measure. The receivers can be:
Event types are the means and signal characteristics of your events. There are two main types of events used when high timing accuracy is needed:
The main information of a shared event is the time when it was timestamped. This is what will allow the synchronization of our data streams. However, usually events can also contain numeric information in the case of TTL and any string information in the case of TCP/IP. It is quite advisable to send your events at specific points of times during your presentation. In this way, your events will contain three types of information:
This approach is quite useful if you want to analyze your data separately (eye tracking data in the eye tracking software and other biometric data in a dedicated software with appropriate biometric analysis tools) as both data streams will contain all the experimental information related with trial onset times.


The children overhead is calculated by adding all period values of the child functions so that it can show the total overhead of the higher level functions even if they don't directly execute much. Children here means functions that are called from another (parent) function.
It might be confusing that the sum of all the children overhead values exceeds 100% since each of them is already an accumulation of self overhead of its child functions. But with this enabled, users can find which function has the most overhead even if samples are spread over the children.
Consider the following example; there are three functions like below.
.ft C
void foo(void) {
 /* do something */
}
void bar(void) {
 /* do something */
 foo();
}
int main(void) {
 bar()
 return 0;
}
.ft
In this case foo is a child of bar, and bar is an immediate child of main so foo also is a child of main. In other words, main is a parent of foo and bar, and bar is a parent of foo.
Suppose all samples are recorded in foo and bar only. When it's recorded with callchains the output will show something like below in the usual (self-overhead-only) output of perf report:
.ft C
Overhead Symbol
........ .....................
 60.00% foo
 |
 --- foo
 bar
 main
 __libc_start_main
 40.00% bar
 |
 --- bar
 main
 __libc_start_main
.ft
When the --children option is enabled, the self overhead values of child functions (i.e. foo and bar) are added to the parents to calculate the children overhead. In this case the report could be displayed as:
.ft C
Children Self Symbol
........ ........ ....................
 100.00% 0.00% __libc_start_main
 |
 --- __libc_start_main
 100.00% 0.00% main
 |
 --- main
 __libc_start_main
 100.00% 40.00% bar
 |
 --- bar
 main
 __libc_start_main
 60.00% 60.00% foo
 |
 --- foo
 bar
 main
 __libc_start_main
.ft
In the above output, the self overhead of foo (60%) was add to the children overhead of bar, main and __libc_start_main. Likewise, the self overhead of bar (40%) was added to the children overhead of main and \_\_libc_start_main.
So \_\_libc_start_main and main are shown first since they have same (100%) children overhead (even though they have zero self overhead) and they are the parents of foo and bar.
Since v3.16 the children overhead is shown by default and the output is sorted by its values. The children overhead is disabled by specifying --no-children option on the command line or by adding report.children = false or top.children = false in the perf config file.

An Urban Explorer's Guide To Finding & Exploring Secret Bunkers
By Matt Scofield
February 19, 2020 6:00 AM ‐ UndergroundUrbExLong Reads
Government Bunker Ahrweiler
I've been fascinated by secret underground bunkers for 20 years or more, I've been lucky enough to have visited some of the most secure underground hideouts in the country and have researched hundreds of sites across the UK.
Bunker exploration is a subset of urban exploration, a closely related past time which involves exploring and photographing decaying and forgotten man-made structures. Bunker exploration focuses on man-made and man-used underground spaces, and therefore shouldn't be confused with the hobbies spelunking, caving or potholing, which focus on natural cave systems.
In this guide to bunker exploration I will share some of the techniques that urban explorers use to find bunkers and underground structures, tips on how to safely gain access and advice on staying safe and making the most of your time underground.
Bunkers are generally categorised by their usage. For example an artillery bunker for defending weapons and ammunition against enemy fire. Industrial bunkers, which house data storage and underground control centres. Personal bunkers are generally constructed within a house. Munitions bunkers are used to store high explosives in order to prevent and contain any potential blasts.
However in the world of bunker exploration, explorers categorise the locations they visit based on its method of construction. This is because the bunkers are usually now abandoned, so their most recent use is of less importance when you consider that bunkers often go through several different uses during their lifetime and often start out as something completely different.
Urban explorers tend to recognise and even discover bunkers to explore based on the following traits.
Purpose Built
Cheyenne Mountain Complex
Purpose built bunkers are generally either semi-sunk concrete reinforced blockhouses, facilities constructed just below the surface of the ground using a technique called "cut and cover", or a network of chambers and tunnels excavated underground or within a hill or mountain. Essentially, purpose built bunkers are holes in the ground that didn't exist before the bunker was constructed. They can range from being partially above ground through to being fully subterranean deep-level shelters.
One of the most famous purpose built bunkers is the Cheyenne Mountain Complex, a US military bunker built into the side of a mountain near Colorado Springs. Building a bunker from scratch costs a lot of money. The Cheyenne Mountain Complex cost about $140 million back in the 1960s, that's around or $1 billion in today's money.
One of the bunker's can be seen here heading South along East Main Road.

A cheaper option than building a bunker from scratch is to re-purpose an existing underground space. Most commonly this is cave networks or underground mines or quarries, which are converted into secure underground locations. This technique was widely used in Wiltshire in the run up to the two World Wars and the Cold War.
Several former stone quarries were converted in to huge underground ammunition stores, subterranean aircraft factories and armed forces command centres. These type of bunkers are most prevalent in Wiltshire, but similar structures built within similar underground spaces exist all around the world.
One of the most impressive examples of this type of facility is the mammoth Burlington bunker in Corsham. It's less of an underground bunker and more like a subterranean city, its tunnels and roadways seem to stretch endlessly and the whole complex is constructed in a former stone quarry.

Hidden Bunkers
Whitehall Ministry Of Defence, London
Another method of bunker building is to construct the facility under or within a building. This can mean building a hardened network of chambers in the building's foundations at the same time the building is being constructed, or an existing basement is retrofitted, hardened and converted into a bunker. In Switzerland, there is an unusually large number of this sort of bunker because of a law requiring protective shelters to be constructed for all new buildings since 1963.
The most famous examples of bunkers of this kind are in central London. The British's government's PINDAR bunker was constructed in the 1990s beneath the Ministry of Defence headquarters on Whitehall and includes COBRA, Cabinet Office Briefing Room A.
Just across the road is Winston Churchill's Cabinet War Rooms, built in a reinforced basement beneath the treasury building. The bunker is now one of London's most famous tourist attractions.
Nuclear Bunkers
Hack Green Nuclear Bunker
Nuclear bunkers can be constructed in any of the three previously mentioned methods, but they tend to have very distinctive design elements, characteristics and, because they are more modern having been built during the Cold War, tend to be in better condition and have more interesting features.
Nuclear bunkers were still being constructed in the UK as far into the Cold War as the early-90s. They are constructed to a much more robust standard of engineering compared to older wartime bunkers as they needed to be able to offer blast protection and protect their inhabitants from the dangers of radioactive fallout.
Because nuclear bunkers were kept on standby until the late-80s and early-90s, they are generally still in very good condition and the specific details of their uses are better documented. A great example of this is the Hack Green nuclear bunker in Nantwich, Cheshire. It is now open to the public as a museum, which perfectly demonstrates how interesting bunkers of it era are. It's packed full of broadcast, monitoring and survival equipment from the era and the purpose of every room in the two-level bunker is understood.
How To Spot A Bunker
Admiralty Citadel - Horse Guards Parade, London
If you're reading this page then you probably already have some interest in secret bunkers, perhaps you've been driving a long and noticed a suspicious looking mound of grass in an otherwise flat area at the roadside or a hardened basement-level door in the side of a local building. But how can you find out what's behind these doors?
If the door is in the side of a building then there's no easy way to find out. The door could be a fire exit from a lower level of the building or even access to underground services. Many cities have underground electrical substations for example.
There may still be a few telltale signs. Obviously a bunker won't have any windows, so if there are none at the same level as the door, then this may indicate a shelter of some kind.
You should also look for ventilation, a bunker will almost always have independent air ventilation and filtrations systems, separate from the rest of the building. This will likely be more than small vents on the wall and is more likely to be large ventilation ducts or standalone air vents popping up out of the ground near the door.
Even after discovering air vents and a lack of windows, it's still going to be very hard to determine what's behind the door. You may need to find out who owns the building. If it is owned by the government or a local council then it is possible they have some kind of shelter under their offices. This might also be the case if the building is occupied by the emergency services or utility providers, such as gas, water and electric companies.
It's a long shot, but step back and take a look at the building's roof. You might find that if there is a bunker hidden below the building that there is some sort of communications array on the roof. The purpose of most bunkers is to maintain the smooth running of the country in the event of a disaster, and this requires good communications access.
Fortunately, other types of bunkers are easier to spot. Any purpose built bunker will normally have a very visible and very bunker like entrance. The entrance to any underground space which has been re-purposed will also look distinctly bunker-like, but still these can be hard to spot and other less exciting entrances can look like bunkers.
A lot of bunkers are semi-sunk, meaning that they are built in a hole in the ground but their upper level or levels are housed in a steel reinforced concrete mass above ground level. One such fortress can be found right in the middle of busy central London on Horse Guards Parade. Despite the fact it's so visible and imposing, most tourists and locals walk past the huge structure without questioning what's inside it.
This type of bunker is very easy to spot, the massive concrete block will have no windows and no doors apart from one huge metal blast door. There's often usually large vents on the side of the building and many bunkers of this type will have a small communications mast near by or on its roof.
Hack Green Bunker
Bunkers which are entirely subterranean have equally as identifiable surface features, but there are other structures that can be mistaken for bunkers.
When it comes to getting into an underground hideout, there's only three options...
Adit - a horizontal or almost horizontal entrance into the ground. This is probably the most obvious type of entrance. If you see a doorway leading into the side of a mountain or hill, then there's clearly something underground there. Although, it could be nothing more than an underground water reservoir, which does look very bunker like.
Slope shaft - an inclined entrance consisting of a doorway leading to steps that descend down to bunker level. This sort of entrance can be quite hard to spot, but when you stumble across one it's pretty obvious what it is. You'll normally see a door on the side of a small mound or building. The opposite side of the building will slope off into the ground, which clearly indicates that all that's behind the door is a tunnel into the ground.
Vertical shaft - a shaft which

Carter Aviation Technologies LLC, working in conjunction with Carter Aerospace Development LLC, has made significant progress as performance flight testing of its Slowed-Rotor/Compound prototype, the proof of concept demonstrator, continues, the company announced.
The proof of concept is a variant of the company's four-passenger vertical takeoff and landing aircraft, known as the SR/C 4-Place PAV.
The proof of concept is continuing to expand the high speed/slowed rotor envelope, the company said in a news release. During November, performance flight testing yielded the following results:
■ Rotor slowed to 106 rpm.
■ By significantly slowing the rotor rpm (to less than half that of a comparably sized helicopter), thus far, a lift-to-drag value of 12 — around 2½ times better than the most efficient helicopters. Lift-to-drag is a measure of the efficiency of an aircraft (lift or weight divided by drag or thrust). Higher lift-to-drag ratios are related to enhanced speed, fuel economy, climb performance and glide ratio.
■ An advance ratio of 0.85. The advance ratio is calculated by dividing the forward airspeed of the aircraft by the tip speed of the rotor. As the rotor rpm is reduced, the advance ratio increases. As the advance ratio increases, drag on the rotor decreases dramatically (resulting in increased efficiency).
■ These achievements clear the way for the proof of concept to achieve speeds in excess of 200 knots at 25,000 feet and 350 horsepower with the test weight of 3,950 pounds.
Additionally, the proof of concept has proved its VTOL capability, achieved speeds in excess of 140 knots on 200 horsepower and an altitude of 12,000 feet, the company said.
The company said it will continue to expand the high speed/slowed rotor envelope at ever-increasing altitudes, and will gather more data on flight efficiencies under those conditions.

India is eager to establish international aviation hubs in the nation by taking advantage of its burgeoning international passenger flow that included civil aviation minister Jyotiraditya Scindia.
With a substantial amount of traffic—about 155 million domestic and 60 million foreign passengers—the government is investigating the establishment of international aviation hubs, with a trial project slated to begin in Delhi.
Additionally, the government wants to provide local and international airlines more flying rights for "point-to-point" traffic. New Delhi is allegedly against giving more flying rights to nations that have used Indian traffic to establish their own aviation hubs.
Unlike the hub-and-spoke approach, which involves flying passengers from smaller "spoke" airports to a central "hub" airport and then transferring them to flights going to other hubs, direct point-to-point flights allow passengers to travel directly to their destination without the need for stopovers.
"Any country that wishes to enter and receive point-to-point traffic beyond a five- to six-hour flying radius is welcome to do so," Scindia stated.
The shift in governmental perspective coincides with Indian carriers, including Air India and IndiGo, continuing to press forward with their global growth due to an increase in air travel.
Global aviation hubs cut down on travel time by ensuring instantaneous connectivity between domestic and international planes.
According to Scindia, the ministry of civil aviation is working with the ministries of finance, tourism, external affairs, and home affairs to create a detailed strategy and assign roles.
International airlines are drawn to India's burgeoning aviation sector because of the country's rapid domestic aviation recovery. According to data, air traffic in December exceeded pre-COVID levels and reached a record 13.8 million passengers.

Over the past decade, for-profit career colleges have faced significant scrutiny and increased governmental regulation. Even with the skepticism of critics, for-profit enrollments surged and had one of the fastest enrollment growths among higher education sectors. For-profit career colleges are typically known for their predatory marketing practices and exorbitant costs. However, there is a significant concern surrounding why students would attend an institution with such a high cost and a socially perceived low-probability of return on investment (Cellini, 2012; Iloh & Tierney, 2013). This study employs a case study methodology to examine the decision-making process of students who selected for-profit career colleges instead of community colleges in northeast Florida. The researcher utilizes Levin and Milgrom's Rational Choice Theory which is based upon the premise that individuals have preferences and make decisions based upon those preferences (Levin & Milgrom, 2004). In this qualitative study, the researcher utilized document evidence, semi-structured interviews, and focus groups to examine how students arrived at their choice to attend a for-profit career college instead of a lesser expensive community college. The findings of the study provide a framework for higher education practitioners and leaders to utilize the information gathered to improve or modify their current admission and recruitment strategies to increase enrollment in community colleges among non-traditional students.


Density Functional Theory Calculations of Electronic and Electrical Properties of Pure Graphene and Fluorine Graphene Sheets
Abstract
Gaussian View 5.0.8 code was used to design the pure graphene sheet GR1and the fluorine doped samples GR2 and GR3. The relaxation of these structureswas done using the SIESTA-trunk-462 code. All calculations are carried out usingGOLLUM code. The result shows the presence of fluorine atoms in the sheet hasno effect on the geometrical parameters of carbon-carbon bonds. Pure graphenesheet has zero band gap, high electronic softness and high electrical and thermalconductivities due to the multi channels of electron transport in comparison withthe two doped graphene sheets. The presence of fluorine atoms in the rings leadsto raise the energy gap and decrease the open channels of electron transfer. Theelectrical conductivity is decreasing linearly proportional to the number of addedfluorine atoms, the I-V curve of the studied graphene sheets is analyzed, the resultshows that the pure graphene sheet behave as pure resistance.

Things are not always what they seem. Common sense and intuition can let us down as we shall see in these examples. What seems obvious is not always true and results always need to be proved in mathematics, that is what pure mathematics is all about. Suppose in some contest A always beats B and B always beats C, then would you expect A to beat C?
Compare this idea to the relation 'greater than' for numbers. For example if a, b and c are real numbers and we know that a > b and b > c then it must follow that a > c. This property of the relation is called 'transitivity' in mathematics and we come to expect it, so when a relation arises that is not transitive, it may come as a surprise. Relations are not always transitive however, if Ann likes Ben and Ben likes Cath it does not necessarily follow that Ann likes Cath.
In the first example Voting Paradox there are 3 candidates for election. The voters have to rank them in order of preference. Consider the case where 3 voters cast the following votes: ABC, BCA and CAB:
A beats B by 2 choices to 1
B beats C by 2 choices to 1
but A cannot be the preferred candidate because A loses to C, again by 2 choices to 1.
This is an example of intransitivity. You can imagine it happening on an interview panel with three interviewers and three candidates. Can you find the probability of an outcome like this with no outright winner where there are 3 candidates A, B and C, and 3 voters, who place the candidates in order of preference? This was a problem from August 1998 and its solution is here.
The second example 'Winning Team'; involves nine runners belonging to three clubs. Runners A, F and H belong to the Cyber Club, runners B, D and I belong to the Champs Club and runners C, E and G belong to the Kings Club. Whenever they run in the same race A always beats B, and B always beats C, and C always beats D etc. so that they always finish in the order A, B, C, D, E, F, G, H, I.
The tournament consists of three races with 6 runners in each race and the winner scores 6 points, the second 5 points, the third 4 points, the fourth 3 points, the fifth 2 points and the last one 1 point, a total of 21 points between the two teams so there is always a winning team. You can easily calculate the points when the Cybers run against the Champs, the Cybers win with 11 points to the Champs 10 points. Now find the results when the Champs run against the Kings. Which is the best team? What happens when the Cybers run against the Kings? This problem, called Winning Team, appeared in October 1998 with subsequent discussion of the solutions.
The third example 'Dicey' involves probabilities rather than events which always happen. Dicey is a game for two players, each throws their own die and the highest score wins. Four fair dice (Efron's dice) are marked on their six faces, using the mathematical constants $\pi$, $e$ and $\phi$ (where $\phi$ is the divine proportion or golden ratio) as follows:
A: 4 4 4 4 0 0
B: $\pi \;$ $\pi \;$ $\pi \;$ $\pi$ $\pi$ $\pi$ where $\pi$ is approximately 3.142
C: $e$ $e$ $e$ $e$ 7 7 where $e$ is approximately 2.718
D: 5 5 5 $\phi \;$ $\phi \;$ $\phi \;$ where $\phi$ is approximately 1.618
You play the game with your friend Jo and you invite Jo to choose first, and to choose ANY one of the dice. Then you can always choose another die so that you will have a better chance of winning than Jo. Now Jo may think this is unfair and want to play with the die you chose thinking it is the best one. In that case you can always chose another die so that you still have a better chance of winning than Jo. Consider all the cases and decide what choice you will make in each case. Is one of the dice the best one?
Does it make any difference if the dice are marked with 3 instead of $\pi$, 2 instead of $e$ and 1 instead of $\phi$?
Dicey features in one of the January 1999 problems.
For more on this subject you might like to read the chapter 'Nontransitive dice and other probability paradoxes' in Martin Gardner's book 'Wheels, Life and other Mathematical Amusements' published by W.H.Freeman in 1983.

December 14, 2008 Dutch designer Neils Smeltink's clever multifunctional bike design can adapt to the needs of children as they become older by easily transforming from a bicycle to a scooter or a walking bike. Younger children will love to use it as a walking bike or scooter while older children can use it as a real bike.
The "Kid Balance" is great as a walking bike for younger children and will teach important motor skills such as balance, coordination and how to project themselves forward. Once they become confident, you simply add on a crank axle and you have a bicycle with pedals.
The conversion from scooter is just as simple, you pull the handle and the scooter becomes a walking bike.

Rohingya (Ruáingga) is a language spoken by the Rohingya people of Arakan (Rakhine), Burma (Myanmar). It is smiliar to the Chittagonian language spoken in the neighboring southeastern Chittagong Division of Bangladesh..
Various writing systems are used, including Arabic, Urdu, Hanifi-Script and Burmese, and the newer Rohingyalish, based on the Roman alphabet.
Written in Arabic script, the first Rohingya language texts are more than 300 years old. While Arakan was under British rule (1826–1948), the Rohingya people used mainly English and Urdu for written communication. Since independence in 1948, Burmese has been used in all official communications. Since the early 1960s, Rohingya scholars have started to realize the need for a writing system suited to their own language.
Molana Hanif and his colleagues developed a new set of right-to-left oriented characters based mainly on Arabic script, with a few borrowings from Roman and Burmese. This approach was an improvement and was appreciated by Rohingya Islamic scholars, used to studying in Arabic and Urdu. However, the new script was criticized because the characters were very similar to each other, requiring longer...

Can I Get Pregnant If…
Our healthcare team receives lots of questions from people wondering "can I get pregnant if…." Here you'll find answers to common questions about how a pregnancy can occur. If you have any other questions, you can visit our clinic at 280 Lester St during regular operating hours.
Can I Get Pregnant If…
We've never had intercourse (sex)?
Yes, but it is rare. If semen or pre-ejaculate (pre-cum) comes into contact with the opening of the vagina or the vulva, the sperm may survive and travel up the vaginal canal, through the cervix, uterus and fallopian tubes. If a person is ovulating, or about to ovulate, there is a possibility that the sperm can fertilize an egg in the fallopian tubes, resulting in pregnancy. The best way to keep sperm from fertilizing an egg cell is to make sure that no semen comes in contact with the genitals (vulva and vaginal opening). For more information about various methods of preventing pregnancy (birth control options), click here.
We have anal sex?
The anus is part of the digestive system. This system begins in a person's mouth, and ends with the anus. Since the reproductive system and the digestive system are not connected, sperm that enters the anus cannot swim through the body to reach an egg cell in the reproductive system.
It is possible to get pregnant if someone has anal intercourse and the semen or ejaculate leaks out of the anus and into the vagina; or if ejaculated semen is near the opening of the vagina and that semen happens to work its way deep into the vaginal opening. So if the person who ejaculates does not wear a condom, or it slips off, or is worn incorrectly, there is a chance that some sperm may get into the vagina and a pregnancy could occur.
We have oral sex?
There is no risk of pregnancy associated with oral sex. This is because when semen enters the mouth and is swallowed (which is not a necessary step), it enters the digestive system. The digestive system is completely separate from the reproductive system, which is the part of the body responsible for pregnancy. For some tips on safer oral sex, click here.
When the person is having their period/monthly bleed?
Yes, this is technically possible, and has to do with the life cycle of the sperm and egg cells. The egg cell can live for about 24 hours after it has been released from the ovary (this is called ovulation). On the other hand, sperm can live from five to seven days inside of a vagina, particularly in the presence of fertile cervical fluid (this looks like egg-white).
Sometimes, fertile cervical fluid can be present towards the end of someone's period. Since sperm can live up to seven days in this fluid, it is possible for pregnancy to occur if they ovulate within that time frame. For example, if someone has unprotected sex on Sunday and still has their period with some fertile cervical mucous present, sperm can live in their body until the following Saturday. If they ovulate during that week, there could be sperm available to fertilize the egg, which could result in pregnancy.
From sitting in a hot tub?
Sometimes people are worried that they could possibly get pregnant from sitting in a hot tub that someone may have ejaculated in. The good news is that sperm die once they hit the hot tub water, before they could reach someone's vulva and vagina.
However, having actual intercourse in a hot tub, hot shower, or in any kind of watery environment does not protect against pregnancy or sexually transmitted infections.
Even if I have used the Emergency Contraceptive Pill (ECP)?
Yes; emergency contraception lowers the risk, but does not completely eliminate it.
The Emergency Contraceptive Pill (ECP) usually refers to a progestin pill like Plan B, Contingency 1, Norlevo, Next Choice, or Option 2. These pills can prevent a pregnancy from occurring if taken within five days after having unprotected sex (or any other incident that might result in sperm entering the vagina), but the sooner someone takes them after sex the more likely they are to work.
Plan B and other pills like it can reduce the risk of pregnancy by approximately 50%. They will not work if someone is already pregnant or if too much time went by after unprotected intercourse.
A prescription is not needed to purchase emergency pills like Plan B. They are available for free at youth clinics, or at low cost at Options for Sexual Health clinics, walk in clinics, and doctor's offices. They are also available from a pharmacy without a prescription for approximately $40.
There is also a new kind of emergency contraceptive pill available in Canada called Ella. It is available by prescription and can also be taken up to 5 days after sex. It is approximately 60% effective and does not lose effectiveness as quickly over time as progestin based emergency pills like Plan B.
If someone has had unprotected sex, and is concerned about the risk of pregnancy, an emergency insertion of a copper IUD is the most effective method of emergency contraception (99% effective when inserted up to 7 days after unprotected intercourse). For more information on emergency IUD insertion click here.
It's the first time we have sex?
Yes, it is absolutely possible to become pregnant after having vaginal sex for the first time. It has been a long standing myth that someone cannot get pregnant the first time they have sex, and this has led to many unplanned pregnancies.
Anytime a person with sperm and person with an ovum (egg cell) have penis-vagina intercourse, it is possible for pregnancy to occur – all that needs to happen is for a sperm to get to an egg cell. The risk of pregnancy is greatly reduced through the use of birth control.
If the partner pulls out before they ejaculate?
Yes. This is called the withdrawal method of birth control, but it is only ~73% effective in actual use because the person with a penis may not pull out in time before ejaculating; also, there may be sperm in the drops of fluid that comes out of the penis before ejaculation (pre-cum).
It is more likely that sperm will be present in pre-ejaculate if a man has ejaculated in the last few hours. This is because leftover sperm may still be present in the urethra. If ejaculation has occurred prior to intercourse, the person who ejaculated should urinate and wipe off the tip of their penis before intercourse to remove any sperm from the previous ejaculation, as sperm could have been trapped in the urethral lining or folds of skin and can therefore be present when subsequent acts of intercourse take place.
The person with a vulva is on top?
No matter what position a couple is having sex in, if ejaculate enters into the vagina, there is the possibility of pregnancy. The effect of gravity will not affect a person's risk of pregnancy. However, couples can enjoy sex in any position that feels good for them and use condoms and other methods of birth control to prevent a pregnancy from occurring.
From masturbating?
Thankfully, no! Pregnancy can only occur if there is sperm to meet the egg cell. By touching genitals for pleasure with hands or toys, someone is not at risk for becoming pregnant (unless there is fresh wet ejaculate that has been recently ejaculated onto their hand or toy).

What Are the Different Types of Birth Control?
Advancements in birth control have skyrocketed with recent technology and research and today, there are many options available for both men and women. With all of these choices, it may be hard to decide which is best for you. Some factors to consider when choosing a birth control method include:
 - Your lifestyle (i.e. how often will you remember to take your birth control?)
 - It's level of effectiveness
 - How long the birth control method takes to kick in
 - What happens when you stop taking birth control
 - Possible side effects of that form of birth control
This article will explain some of the different types of birth control methods and some pros and cons for each. We will separate birth control into three categories – hormonal birth control methods, barrier protection, and natural birth control methods.
Hormonal Birth Control Methods
Hormonal birth control methods are the ones we hear about most because they come in many forms and hormone levels. Let's look at some of the most common types of hormonal birth control methods and the pros and cons for each.
Birth Control Patch
A birth control patch is a thin piece of plastic that adheres to skin, usually your upper arm, and release hormones that way. The hormones usually include both estrogen and progestin. The patch does require a prescription from a medical professional or gynecologist, and is covered under many insurances.
 - Pros of the Birth Control Patch:
 - One of the main benefits of the birth control patch is that it is easy to use and only needs to be changed once a week. Compared to taking a daily pill, the patch is a little easier to remember to apply. All you really have to do to have a high rate of effectiveness is change it at the right time every week and wear it as it's intended.
 - Another benefit of the birth control patch is that it doesn't interfere with sex and protects you 24/7. This can be good for "in the moment"

Shuster Coat of Arms / Shuster Family Crest
The German surname of SHUSTER was an occupational name for a turner, originally derived from the Middle German word SCHUSSEL, meaning a small wooden bowl. The name was also adopted by Ashkenazic Jews. Many of the modern family names throughout Europe reflect the profession or occupation of their forbears in the Middle Ages and derive from the position held by their ancestors in the village, noble household or religious community in which they lived and worked. The addition of their profession to their birth name made it easier to identify individual tradesmen and craftsmen. As generations passed and families moved around, so the original identifying names developed into the corrupted but simpler versions that we recognise today. The name is also spelt SCHOTTE, SCHOTTLER, SCHUSSEL and SCHOTELDREYER. The first hereditary surnames on German soil are found in the second half of the 12th century, slightly later than in England and France. However, it was not until the 16th century that they became stabilized. The practice of adopting hereditary surnames began in the southern areas of Germany, and gradually spread northwards during the Middle Ages. A notable member of the name was Sir Arthur SCHUSTER (_PHONE_) the British physicist, born in Frankfurt of Jewish parents. He studied at Heidelberg and Cambridge, and became professor of applied mathematics (1881) and physics (_PHONE_) at Manchester. He carried out important pioneer work in spectroscopy and terrestrial magnetism. The word Heraldry is derived from the German HEER, (a host, an army) and HELD, (champion): the term BLASON, by which the science is denoted in French, English, Italian and German, has most probably its origin in the German word 'BLAZEN' (to blow the horn). Whenever a new knight appeared at a Tournament, the herald sounded the trumpet, and as competitors attended with closed vizors, it was his duty to explain the bearing of the shield or coat-armour belonging to each. Thus, the knowledge of the various devices and symbols was called 'Heraldry'. The Germans transmitted the word to the French, and it reached England after the Norman Conquest of 1066.

Simulated Worlds Analogy
c. 1991 / (085)
Thompson describes how advocates for artificial life view consciousness as the result of combinations of minute particles. He proposes that if we consider computer symbols as the "little parts" utilized to produce "simulated life" within nature, we can then regard nature as a vast parallel processor. Certain characteristics of this model, Thompson notes, bear a surprising resemblance to the Puranic concept of maya.


correct order with the preposition "on" between them.
 Example 6.3.1: Calculating Force
 What force is exerted on the tooth in Figure if the tension in the wire is 25.0 N? Note that the force applied to the tooth is smaller than the tension in the wire, but this is necessitated by practical considerations of how force can be applied in the mouth. Explicitly show how you follow steps in the Problem-Solving Strategy for Newton's laws of motion.
 Figure 6.3.1 Braces are used to apply forces to teeth to realign them. Shown in this figure are the tensions applied by the wire to the protruding tooth. The total force applied to the tooth by the wire, \(F_{app} \), points straight toward the back of the mouth.
 1. Use Newton's laws since we are looking for forces.
 2. Draw a free-body diagram:
 Figure 6.3.2.
 3. The tension is given as \( T = 25.0 \space N. \) Fond \(F_{app}.\) Using Newton's laws gives: \( \sum{F_y} = 0 \), so that applied force is due to the y-components of the two tensions: \(F_{app} = 2T \space sin \space \theta = 2(25.0 \space N) \space sin (15^o) = 12.9 \space N. \) The x-components of the tension cancel. \( \sum{F_x} = 0 \).
 4. This seems reasonable, since the applied tensions should be greater than the force applied to the tooth.
 Contact and Long Range Forces
 An interaction and the accompanying agent of interaction—the force—can occur between objects that are in contact as well as between objects that are widely separated in space. An example of the former is the force you apply on an object when you push it, or the force your bat exerts on a ball as you hit it into left field. An example of the latter is the force of gravity the Earth exerts on an orbiting satellite 200 miles above the surface of the Earth. The gravitational interaction between the Earth and other objects which may or may not be touching the Earth is said to be long range. The interaction and the force, the agent of the interaction, continue to exist, even when there is no direct contact. This is distinctly different from the example of the bat and ball. The force of the bat on the ball is often referred to as a contact force, since there is no interaction or force if the bat and ball are not in actual contact (in a macroscopic sense).

At Sydney Adventist College, a graduate teacher begins her lesson in science by asking her students to discuss whether a stream in a photograph is clean or dirty. She identifies students' responses as potential 'characteristics' of the water's quality, and organises these in a concept diagram. In the next lesson students undertake a practical investigation of a nearby creek's water quality using data sampling equipment. This data is collated in the following lesson.
The graduate teacher plans a lesson sequence in science, exploring and testing how students learn through practical inquiry, analysing data and sharing results. While the extracts selected for the video do not show the planning processes for the sequence or the individual lessons, she is confidently in control of the content and the teaching resources at her disposal at each stage of the learning activities. She introduces the language of scientific inquiry naturally and appropriately, she builds understanding through developing thinking strategies, and uses simple yet appropriate data logging technologies for the fieldwork.

Python Connection to MongoDB
MongoDB is one of the most popular NoSQL databases, which allows developers to easily work with the stored data. This tutorial provides an example of connection to the MongoDB server from your Python application.
1. In our case we have an environment with Python and MongoDB containers inside (you can create such one at any time), but this instruction is suitable for the remote servers as well.Python MongoDB environment
2. Connect your compute node via CirrusGrid SSH Gate.Jelastic SSH Gate
3. Install a MongoDB driver for Python using the command below:
pip install pymongo
install MongoDb driver for Python
4. Set up a simple script to check your DB server connection. For that use any preferable text editor and create a file with the .py extension (e.g. vim
from pymongo import MongoClient
client = MongoClient("mongodb://{user}:{password}@{host}:{port}")
db = client.{database}
try: db.command("serverStatus")
except Exception as e: print(e)
else: print("You are connected!")
Just adjust the connection string with a relevant date, which can be gained from email for your MongoDB node:
 - {user} – username to log into database with
 - {password} – password for the appropriate user
 - {host} – link to your MongoDB container
 - {port} – port to be used for connection (use the default one – 27017)
 - {database} – database to be accessed (e.g. the default admin one)
MongoDB connection script
This script will connect to the specified database server and will try to get its status. If any error occurs in the process, its description will be printed; otherwise, just a "You are connected!" string will be displayed.
5. So, execute code in the file by running the appropriate command:
run DB connection script
The "You are connected!" string ensures, that application was able to connect the DB server successfully, so you can start managing database node by extending code with other operations.

The Polish side expressed its will to continue cooperation with the Organization for the Democracy and Economic Development - GUAM.
The meeting of the Deputy Foreign Ministers of GUAM countries ( Georgia, Ukraine, Azerbaijan and Moldova), as well as that of Poland, discussed the prospects for multi-side cooperation in the fields of trade, investment promotion, energy, transport and tourism.
The participants noted the necessity to intensify the role of European Union in GUAM. Poland officials voiced their readiness to render their assistance in implementation of the New European Neighbourhood Policy Action Plan signed with Azerbaijan, Georgia and Moldova.
The GUAM countries and Poland emphasized their adherence for the peaceful settlement of the conflicts existing in the organization's member countries, in accordance with the UN Security Council's resolutions.
Four post-Soviet republics; Georgia, Ukraine, Azerbaijan and Moldova, established the GUAM format in 1997, during a summit of presidents of European Union countries in Strasburg. In 1999, Uzbekistan joined the organization, but left four years later. In 2006, at the first summit of the organization in Kiev a decision was made to announce GUAM as an international organization with a new name; Organization for Democracy and Economic Development - GUAM. Later, such formats as GUAM-Poland, GUAM-USA and GUAM-Japan were established.

The BUG rating system was proposed due to its ability to evaluate luminaire distributions in the context of the impact of light emitted in the various solid angles of the LCS as they apply to light trespass, skyglow, and glare, and was intended to replace the IES vertical cutoff classification system (for example, full cutoff, noncutoff).
The preliminary BUG rating system proposed by the committee included four of the LCS solid angles that contribute to sky-glow: Front Very High (FVH) which captures light emitted in front of the luminaire between 80[degrees] and 90[degrees] above nadir, Back Very High (BVH) which captures light emitted behind the luminaire between 80[degrees] and 90[degrees], Uplight Low (UL) which captures light emitted across all horizontal angles between 90[degrees] and 100[degrees] above nadir, and Uplight High (UH) which captures the light emitted from 100[degrees] above nadir to zenith.
Per TM-15-07, "[LCS] does not provide quantitative lumen limits within each solid angle.
The book starts by articulating the bold proposal that picturing is a matter of sameness of subtended solid angles and proceeds to modify that proposal as necessary to deal with the full range of pictorial subject matters and styles by appealing to the conceptual resources of perceptual experience.
Hopkins claims that we do by proposing that outline shapes and subtended solid angles are nonconceptual contents of experience (contents posited as presenting properties that a perceiver cannot identify by means of concepts or any related--for example, geometric--capacities but that are part of her experience nonetheless).

DAP (Data Access Protocol) client and server for Python.
Implementation of the Data Access Protocol.
This is a Python implementation of the Data Access Protocol, a scientific protocol for data access developed by the OPeNDAP team (_URL_). This implementation is developed from scratch, following the latest specification of the protocol (DAP 2.0 Draft Community Standard 2005/04/27) and based on my experience with OPeNDAP servers on the wild.
Using this module one can access hundreds of scientific datasets from Python programs, accessing data in an efficient, transparent and pythonic way. Arrays are manipulated like normal multi-dimensional arrays (like numpy.array, e.g.), with the fundamental difference that data is downloaded on-the-fly when a variable is sliced. Sequential data can be filtered on the server side before being downloaded, saving bandwith and time.
The module also implements a DAP server, allowing datasets from a multitude of formats (netCDF, Matlab, CSV, GrADS/GRIB files, SQL RDBMS) to be served on the internet. The server specifies a plugin API for supporting new data formats in an easy way. The DAP server is implemented as a WSGI application (see PEP 333), running on a variery of servers, and can be combined with WSGI middleware to support authentication, gzip compression and much more.
The latest version is available in a Subversion repository.

text: This paper considers semi-analytical solutions for a class of generalised logistic partial dierential equations with both point and distributed delays. Both one and two-dimensional geometries are considered. The Galerkin method is used to approximate the governing equations by a system of ordinary dierential delay equations. This method involves assuming a spatial structure for the solution and averaging to obtain the ordinary dierential delay equation models. Semi-analytical results for the stability of the system are derived with the critical parameter value, at which a Hopf bifurcation occurs, found. The results show that diusion acts to stabilise the system, compared to equivalent nondiusive systems and that large delays, which represent feedback from the distant past, act to destabilize the system. Comparisons between semi-analytical and numerical solutions show excellent agreement for steady state and transient solutions, and for the parameter values at which the Hopf bifurcations occur.

Demonstrating Touch & Magnet Based Interactions with a Photo Browser (Piknik)
Abstract
This paper presents an alternative method of interacting with mobile devices. Most modern phones contain magnetometers that output the strength of the surrounding magnetic field in the x, y, and z direction. If a magnet is brought closer to the device (and the magnetometer), the values from the magnetometer will be altered. By determining the change in the altered magnetic field, we can determine the position of the magnet. With the position, we can determine the location of the magnet relative to the screen and detect gestures above the screen in 3D space. We will be building a photo browser & drawing application that will contain implementation for magnet based interactions. Users can flip through, select, and annotate/draw on photos using external magnets.

Introduction
A mobile device has a multitude of sensors ranging from GPS to a barometer. One sensor that is used daily is the capacitive sensor. Capacitive sensors detect anything that is conductive and they are used for touch input in mobile phones. We rely tremendously on touch input to interact with our devices ranging from playing games to checking notifications. However, touch input on mobile devices have its own sets of problems. We are unable to easily interact with our phone due to phones being too large, and not large enough thus limiting user interactions.
Is there a way to provide another method of interaction with your mobile device that expands the capabilities of touch? Another sensor that can be used for alternative methods of interaction is a magnetometer. The magnetometer senses changes in the magnetic field in all three axes (x,y,z) (Ketabdar 2011). If the magnetic field can be detected, would there be a way to alter the magnetic field? This can be accomplished by using an external magnet. The external magnet will alter the magnetic field thus producing different (x,y,z) values.
This new user interaction requires the use of a magnet attached or placed on a finger or embedded in a ring. The use of a magnet and a magnet sensor will increase the area of user interaction around and above the phone. Gestures and taps in 2D and 3D space can be recognized and attached to certain actions. This would allow interaction with a mobile device without physical contact with that device. For example, interacting with your phone while its in your pocket or purse. These are just a few use possibilities of interacting with your phone by using a magnet.
Using the magnet based interactions described above, we will be building a photo browser + drawing application that will allow you to flip through, select, and annotation/draw on photos using magnets and touch. Magnets also can be embedded on physical objects, such as styluses (which will represent paintbrushes). This will allow the user to have a more natural interaction with the app (Ali Mazalek).

Former colliery fan house (27) and drift of c.1958.
Reason for Listing
The Walker fan house at Chatterley Whitfield Colliery, constructed c.1958, is listed at Grade II for the following principal reasons:
* Rarity: fan houses are rare survivals in a national context and, despite the loss of its fan, this example retains its landmark evaseé;
* Architectural interest: it represents a distinctive and significant component from the later phases of the colliery's development;
* Historic interest: the building is fundamental to the understanding, history and appearance of the colliery.
The coal seams in the Chatterley Whitfield area may have been worked from the medieval period but large-scale extraction began in the C19, particularly following the opening of the Biddulph Valley Railway line in the 1860s and the formation of Chatterley Whitfield Collieries Ltd in 1891. By the early C20 the mine workings were focussed around four shafts – known as the Engine Pit, Middle Pit, Institute Pit and Platt Pit. The 1910s saw significant investment including the construction of the new Winstanley shaft in 1913-15, which superseded the adjacent Engine Pit and served the workings of the Middle Pit. Soon after another new shaft was dug, the Hesketh Shaft constructed _PHONE_. This was designed to serve the much deeper coal seams below those worked by the other shafts. By 1928, the colliery employed 4402 men including 249 boys under 16. Following a contraction in production during the labour unrest of the 1920s and the Depression of the 1930s, there was renewed investment in the site including the mechanisation of underground haulage and the construction of new office accommodation and a pithead baths complex. In 1937 the colliery became the first to extract over one million tonnes of coal in a year.
Following the nationalisation of the coal industry in 1947 there was further investment at Chatterley Whitfield. The Walker, or Institute fan house at Chatterley Whitfield is first depicted on a plan of 1958 and it contained an electrically-driven fan. The Walker Brothers' steel 'Indestructible' fan, a direct descendant of the Guibal fan, was patented in 1887 and was a double-inlet type with eight blades, set in a spiral casing with a ventilation shaft or evaseé. Up to 100,000 cubic feet of air per minute could be drawn from the workings through the fan drift and fresh air naturally replaced this through the downcast shafts. During the late C20 the fan drift to Chatterley's Walker fan house was partly converted to form 'sham' offices for museum visitors.
From the 1960s production at the site fell and in the 1970s it was decided to work the remaining coal from Wolstanton Colliery. Production ceased in 1976-77 but the site was opened as a museum two years later. This ensured the survival of the buildings, but the museum closed due to financial difficulties in 1993.
Former colliery fan house (27) and drift of circa 1958.
MATERIALS: the fan house has a brick base and is steel framed with profiled metal cladding; its roof is also clad in metal sheeting. The ventilation shaft has a fabricated steel casing, and the fan drift is covered in mass concrete slabs.
PLAN: rectangular on plan comprising three attached structures: the fan house containing the fan motors and other equipment, the ventilation shaft or evaseé, and a fan drift to the south.
EXTERIOR: north side of fan house has a large entrance with continuous glazing of fifteen lights above. The windows in the west elevation are metal framed, and an exhaust pipe comes out of the east side of the building. To the rear (south) side is the evaseé which has welded steel ribs and plates which form a four-sided tower that flares outwards above mid-height. The concrete-covered drift beyond (south) has a projecting, flat-roofed entrance with steel doors (boarded over) to the west elevation, which is accessed by concrete steps with railings to three sides and a large steel door on its east side.
INTERIOR: not inspected (2013), but understood to retain an electrically-powered fan, DC generator, fan motor on a concrete plinth, gear box and pumps. Much of the floor within the fan house is finished with red quarry tiles. A staircase within the drift leads down to tunnels.

Must Read
On one hand, where the pandemic had gotten the whole world upside down, the work from home (WFH) culture had taken the internet on the roll. From memes to sharing the WFH moments on the internet, people sought all the opportune moments to deal with the global crisis in a mood-light way.
Amid all the dismay, however, one thing that gained tremendous popularity was Pyjama! While the clothing had been a go-to for so many around the world, the lockdown and WFH culture had gained it the status of 'the new cool.'
But here's research to your surprise that may make you think over slipping out of your PJs and hopping into something else, a clothing that is more put-together maybe. Australian researchers have established a link between working in the Pyjamas during the pandemic and deteriorating mental health.
On taking a look at the effects of wearing pyjamas while working, researchers found its astonishing association with recurrent reporting of poor mental health.
As per the study conducted by Australian researchers, 41% of people say that they experienced an enhancement in their productivity when working from home. However, more than one-third of the participants have reported a severe deterioration in their mental health.
Further, 59% of people who wore pyjamas at least once a week while working from home, admitted to experiencing a decline in mental health, as compared to 26% of those who did not wear pyjamas during the day.
Reportedly, researchers also suggest that clothing can have a significant impact on cognition and mental health. Here's how they explained it: "Although we cannot determine whether wearing pyjamas is the cause or consequence of deteriorating mental health, appreciation of the effect of clothing on cognition and mental health is increasing, as it has been observed in hospitalized patients."
It is also observed that if the patients are motivated to wear normal daytime clothes instead of pyjamas, it can add to their mental well-being and even decrease the effect of depression.
Researchers advise changing clothes before beginning the work with the view to lessen the negative effects that the pandemic restrictions have caused to our mental health.
They say, "The simple advice to get changed before beginning work in the morning might partially protect against the effects of Covid‐19 restrictions on mental health, and would be less expensive than the 'fashionable' sleep or loungewear gaining popularity as working from home becomes the norm."

Preoperative splenic artery embolization for massive splenomegaly has been shown to reduce intraoperative hemorrhage during splenectomy. We describe a case of tumor lysis syndrome after proximal splenic artery embolization in a patient with advanced mantle cell lymphoma and splenic involvement. The patient presented initially with hyperkalemia two days after embolization that worsened during splenectomy. He was stabilized, but developed laboratory tumor lysis syndrome with renal failure and expired. High clinical suspicion of tumor lysis syndrome in this setting is advised. Treatment must be started early to avoid serious renal injury and death. Lastly, same day splenectomy and embolization should be considered to decrease the likelihood of developing tumor lysis syndrome.

Disposition of leases and reversions
Power of deposition
Both landlords and tenants have legal estates which may pass to others on sale, by way of gift or under the rules of testate or intestate succession.
Sale of the freehold reversions
The owner of the reversion in fee simple can sell his estate in the land, by conveyance, in the case of unregistered land, and by transfer and registration, in the case of registered land.
Unregistered land
In the case of unregistered land, the purchaser will acquire the fee simple subject to any legal lease which exists, regardless of whether he knew of its existence. This is because: 'Legal rights are good against the world.' Thus the purchaser of the fee simple becomes the tenant's new landlord and takes over most if not all of the original landlord's rights and duties under the lease.
Registered land
Where the lease is granted for not more than seven years it will be an overriding interest under LRA 2002, Sch 3, para 1 and so will bind the purchaser of the fee simple even if he did not know of it.
If the lease is for more than seven years it must have been registered for it to take effect as a legal lease. When this is done the lease will also be noted on the charges register of the landlord's title, and anyone who takes the landlord's estate for valuable consideration will take subject to the lease.
Sale of the lease by the tenant
A tenant can also sell his leasehold estate. The disposition of a lease is usually called an 'assignment.'
Express assignment
Since the assignment of a lease is the conveyance or transfer of a legal estate it must be made by deed.
However, a defective assignment will be regarded in equity as a contract to assign, provided it satisfies the formalities for a contract relating to land. Where such a contract arises, either party may then apply for an order for specific performance to effect a full legal assignment.
Assignment by operation of law
An exception to the requirement for a deed arises where the assignment takes effect due to operation of law. This can be important in cases where a tenant purports to grant a sublease of the property but grants a term which is equivalent or greater than, the unexpired portion of his own lease.
If the purported sublease is for not more than three years it will probably have been made orally or in writing. If the effect of the agreement is to transfer the whole remaining term of the head lease to the 'sublessee' the result appears to be a valid legal assignment without the use of a deed. Lord Greene MR appears to accept this reasoning in Milmo v Carreras [1946], on the ground that such as assignment arose by operation of a rule of law and this approach has more recently been followed in Parc (Battersea) Ltd v Hutchinson [1999].

"Until they see the Kingdom of God having come with power." At the time of

The whole thing is in the future because of hEWS AN, "Until".

There is a textual variation associated with this APOLESEI. In the N-A27
the variant is given as APOLESH supported mostly by Byzantine witnesses but
also by f13, 28, and theta. The future tense is supported by mostly
Alexandrian including apparently P45, and also f1 and some minuscules with
non-byz. tendencies.
The primary reason to go with the reason in the text is that it is the more
difficult reading though the use of the future in a place where the aorist
subj. is expected happens in the NT and some other Hellenistic Greek.
Hence I would agree that this the the future used with the AN which usually
takes a verb in the subjunctive. This is not strange since all
subjunctives are in some way future.
