Will my child get coronavirus at school? Here's some perspective for Aussie parents
As Australian students returned to school this week, they were met with conflicting and changing advice from federal and state governments on the coronavirus outbreak.
The outbreak, which originated in the Chinese city of Wuhan in Hubei province, has killed more than 170 people and spread to at least 16 countries – seven people have been identified with the infection in Australia.
What's the official advice?
The Australian government's initial advice was that any child who had been in contact with an infected person be excluded from school for 14 days. But schools shouldn't exclude children who were well and who had not had any exposure to an infected person that may have come back from China.
This position was updated on Wednesday afternoon when the chief medical officer asked people who have returned from Hubei province, or have had contact with someone who has a suspected or confirmed case of the virus, to stay at home for 14 days.
This update came as four people attending a conference in Germany contracted the virus from a Chinese national who did not show any symptoms until 24-48 hours later.

The Victorian government also updated its advice to match the federal government's.
The NSW government, however, requested children who had visited any part of China in the last two weeks not to attend school or childcare services until 14 days have lapsed from their date of departure from China.
How contagious is the virus?
While the World Health Organisation is meeting to see whether to consider the outbreak a global emergency, it is important to note the risk of a child at school or childcare in Australia being infected remains very low.
The WHO believes for every one person infected with coronavirus, up to 2.5 others can become infected (this is how experts estimate contagion). There have only been seven confirmed cases in Australia so far and the government has put in place strict quarantine strategies to ensure they don't infect others.
A person with seasonal flu is estimated to infect around 1.28 people, but there are thousands of infections during flu season. Unless a child has been in close contact with someone who has coronavirus virus, they are far less likely to catch it from school or childcare than they are to catch the flu during an outbreak.
The novel coronavirus belongs to the same family of coronaviruses as the severe acute respiratory syndrome (SARS) but current evidence shows it is not as infectious. A person infected with SARS was reported to infect up to five others.

During the SARS outbreak, the WHO advised all contacts of suspected or probable cases be placed under active surveillance for ten days and directed to observe voluntary isolation for at least ten days.

With the current coronavirus, WHO advises people to take caution and for countries to implement temperature checks of travellers coming from the affected areas. This is a lesser response than with SARS.
Who decides who goes to school?
During disease outbreaks, authorities are particularly concerned about schools and childcare centres for several reasons. Children are often in close contact with each other and are less likely to adhere to public health messages (such as washing hands and not sharing water bottles).
Children in childcare, especially those younger than two years, are particularly vulnerable because many of them still haven't finished their vaccinations.
This is why following an outbreak, authorities would make decisions to isolate children who might have come in contact with a person with a suspected transmittable disease. Authorities consider several factors when making decisions to isolate people following an outbreak. These include the risk of infection, its modes of transmission and how aggressive it is.
Each Australian state and territory has its own disease surveillance and control branch which develops public health recommendations based on the scientific evidence relating to an outbreak. But some public health messages can also be influenced by political factors.
For instance, the NSW health minister admitted the government's advice was not "medically necessary" but that the government has acted in line with community expectations to ensure the safest possible environment for students.
Read more: Coronavirus: we still haven't learned the lessons from Sars
Decision makers can use something called the "precautionary principle" when issuing advice. This states when there is a serious risk to human health, lack of scientific evidence should not be used to postpone preventive measures.
An independent review set up to investigate the handling of the SARS outbreak in Toronto found decisions were delayed because decision makers felt they didn't have enough evidence to make them. The commission stressed the "importance of the precautionary principle that reasonable efforts to reduce risk need not await scientific proof".
In Australia, there was only one case of SARS, in NSW, in a visitor who caught the infection in their home country. The state's health department advised those who suspected they had been infected not to go to school or public places and seek medical treatment.
Victoria's advice during a SARS outbreak is that
All suspected, probable and confirmed cases will be excluded from school and work until clearance is obtained from the department.
Close contacts of cases or returned travellers from regions of SARS outbreak, as defined by the department, will be allowed to attend school provided that they remain completely asymptomatic.
This advice is less urgent than the current messaging.
In Toronto, three schools were closed during the SARS outbreak but 24 people had died of it there within three months.
Health officials making the decision to close schools during an outbreak weigh the potential benefits of reducing transmission against economic and social costs, difficult ethical issues (such as potential xenophobia) and the disruption of education.
Although the risk to human health is always prioritised, these considerations make decisions difficult, especially when the number of cases is still low.

1.4.- Very important about protocols
There is not good analysis without reliable data and for this purpose Protocols are the Key point. A Protocol is an uniform way to act in all the cases to minimize the bias in the results. In order to design a good Protocol for organizing your data ask you the following questions:
 1. What is the eye operated on?
 2. Which procedure I have followed for the incision, femtosecond or keratome?
 3. Has been the IOL inserted preloaded?
 4. Where is the incision located?
 5. Which system / parameter I have used for measuring the corneal power?
When all the questions match for a serie of patients you have followed a Protocol, but If one answer is different between patients, you are adding noise into your data. Remember, it is the similar a small sample and reliable data than BigData with poorer reliability, if you start to do the data collection in a right way you will achieve your purpose earlier.
Here you have a sample for a protocol:
 1. What is the eye operated on? Right eye
 2. Which procedure I have followed for the incision, femtosecond or keratome? Femtosecond
 3. Has been the IOL inserted preloaded? Yes
 4. Where is the incision located? Temporal (0-180º)
 5. Which system/parameter I have used for measuring the corneal power? IOL Master 500 SimK
For this protocol I have selected the Title: RE-Femto-temp-500
SIA calculator
BigSIA
The incision that is required for IOL implantation during cataract surgery induces astigmatism —this is referred to as surgically induced astigmatism (SIA)— so the total amount of astigmatism to be corrected with the toric IOL must consider the flattening (FE) or steepening (SE) effect on the meridian of the preoperative corneal astigmatism on which the IOL is going to be aligned. The SIA will depend on several factors, including incision type, location and size, and its design or architecture.

Optimize Volume Transfer Methods to Avoid Reagent Concentration Error
Laboratories utilizing liquid handling devices appreciate the efficiency benefits that these important instruments provide. Fast and repeatable volume transfers, however, do not always contribute to accurate assay results. Assays are dependent on reagent concentrations and reagent concentrations are volume-dependent. If a liquid handler is inaccurate in the volumes it dispenses, reagent concentrations can be very different in the reaction vessel when comparing theoretical and experimental concentration values. Undoubtedly, most liquid handlers can be highly precise, but some can also be very inaccurate when default methods/settings are employed. When errors are discovered a game of finger-pointing often occurs – is it the reagent kit? The robot? The tips? The method? The user?
This presentation highlights: (a) the importance in checking volume transfer accuracy for all pipettors associated with a specific assay using a standardized metric; (b) how reagent concentrations are critically affected by as much as 50% when as few as two successive volume transfer steps are inaccurate; and (c) how with simple tools/knowledge, liquid handlers and their associated methods can be quickly optimized to deliver accurate volumes to ensure proper reagent concentrations in a reaction vessel.
This presentation offers specific information for optimizing the pipetting accuracy for the Beckman Coulter Biomek series (FX, NX, and 3000), the Qiagen QIAgility, PerkinElmer Sciclone and a Thermo WellMate bulk dispenser. It is hoped the information provided will help users, programmers and overseers of automated liquid handlers to gain control of liquid handling QA & QC processes to help eliminate liquid handlers as sources of error.
Materials & Methods
All sample solutions were aqueous and all target volumes were measured with the MVS® Multichannel Verification System1. Additionally, only MVS Verification Plates were employed. The MVS was employed to show simple and quick optimization processes for four different liquid handlers. The details pertinent to each optimization process are included, whereas some of the experimental information (tip type, environmental conditions, etc.) are not discussed herein.
Experiment 1
A 1-tip Qiagen QIAgility liquid handler was optimized to wet dispense 2 µL into a 384-well plate by adjusting the p-value.
Experiment 2
An 8- channel Thermo WellMate dispenser was optimized to dispense 25 µL into a 96-well plate by adjusting the cartridge assembly's set screws.
Experiment 3
A 96-tip Beckman Coulter Biomek NXp was optimized for wet-dispensing three target volumes in a 96-well plate (2, 5 and 8 µL) by adjusting the scaling and offset factors as described in Beckman application note2.
Experiment 4
A 96-tip PerkinElmer (Caliper) Sciclone was optimized to dispense 10 µL into a 96-well plate by sequentially adjusting pipetting variables3.
Experiment 1 – Optimizing a Qiagen QIAgility
One can optimize volume transfer of a QIAgility by adjusting the p-value, which changes the amount of liquid pipetted by approximately 0.04 µL/step. Without a "measurement stick" for determining volume transferred to a vessel, however, one cannot make p-value adjustments to improve accuracy. The process for optimizing accuracy is quite simple: (1) perform "as found" testing; (2) determine the volume difference for measured vs. desired; (3) convert the volume difference to p-value steps; (4) add/subtract steps to/from current p-value; (5) re-test with new p-value. In the data presented here, the pre-optimized mean volume was 0.168 µL higher than the desired target of 2 µL (Figure 1). The p-value was decreased by 4.2 steps to 71.16 ([0.168 µL] / [0.04 µL/step] = 4.2) and the 2-µL target was retested and optimized in one simple experiment.
Figure 1. (left) Tweaking the p-value once for the 2-µL dispense improved the relative inaccuracy from 8.4% to 1.25%. (right) Image of Qiagen QIAgility from _URL_.
Experiment 2 – Optimizing a Bulk Dispenser
The volume transfer performance of an 8-tip Thermo WellMate, fitted with a standard bore cartridge, was monitored at 25 µL. Interestingly, though the target volume is relatively high, the performance was pretty good for this common bulk dispenser. Initial testing showed an overall accuracy to be within 5%. Two additional tests were conducted after the set screws were either tightened (to decrease volume transfer) or loosened (to increase volume transfer). Two of the tips (6 and 8, Figure 2) were initially adjusted in the wrong direction, which was immediately obvious in this cause-and-effect testing process. Simply by tweaking the set screws, the tip-by-tip accuracy was optimized within minutes. The as found, pre-optimized mean volume, relative inaccuracy and CV values were 26.15 µL, 4.6% and 2.87%, respectively. The as left, optimized values were 25.03 µL, 0.12% and 0.68%, respectively
Figure 2. The WellMate can be optimized tip-by-tip by adjusting the set-screws within the cartridge assembly.
Experiment 3 – Optimizing a Beckman Coulter Biomek
A Biomek liquid handler can be optimized for pipetting accuracy by adjusting the scaling factor (slope, m) and the offset (y-intercept, b) in the Calibration tab within the Technique Editor. The calibration is based on y = mx + b. However, the scaling factor and offset values are meaningless without a way to measure volume transfer accuracy. Adjusting pipetting accuracy is a simple and effective process: (1) measure volume transfer performance (three or more target volumes is recommended); (2) plot measured vs. theoretically displaced volume2; (3) determine the new slope and offset values; and (4) enter values and re-test. In the example shown, a default non-optimized universal technique was employed to dispense 2, 5 and 8 µL. The as found performance was (linearly) inaccurate: -27.85%, -14.68% and -9.6% (respectively for the three volumes; Figure 3). New scaling and offset factors were calculated and employed, and in one test, the relative inaccuracies improved to -0.05%, -1.14% and 1.05%., respectively.
Figure 3. (left) The measured volumes for the Biomek NX as tested before, and after, optimization. The scaling and offset values were changed from 1 and 0 to 1.032 and 0.548, respectively, for the as found and as left data sets. (right) Image of Biomek NX from _URL_.
Experiment 4 – Optimizing via Parameter Adjustment
The volume transfer performance of a 96-tip Sciclone was employed to show that sequentially tweaking volume transfer parameters, on nearly any type of air-displacement liquid handler with any tip configuration, can have a direct impact on the amount of liquid transferred3. Table 1 shows the parameters and values used for each 10-µL target volume dispense, as well as the resulting volume measurement statistics for each trial (A-D). Of most important note, the original settings employed showed an inaccuracy of -32% (note that all CVs are within 4%). By introducing a 5-µL leading air gap, the accuracy immediately improved to -8.2%. Though this process for optimizing the automated task could have been performed with alternative approaches (different parameters, different order, defining liquid classes, etc.), it highlights the importance of performing a cause and-effect volume verification method during method optimization. The results show that after three sequential parameter adjustments, the optimized data reflect mean volume, relative inaccuracy and CV values of 9.97 µL, -0.30% and 0.80%, respectively.
Table 1. Sequentially Adjusting Liquid Handler Parameters has a Direct Impact on the Transferred Target Volume*
*Subset of data from reference 3. The mean volume in trial C was 9.12 µL,so the requested volume in the software for trial D was increased by 0.88 µL before running the final (optimized) transfer.
Accuracy Matters in Liquid Handling
Resulting Reagent Concentrations are Very Different When as Few as One or Two Transfers are Inaccurate
Compound concentration values can vary by > 30% if one transfer is inaccurate and by > 50% if two successive transfer steps are inaccurate (Table 2). The mean preand post-optimization volumes from Experiments 1 to 4 were employed in two simple calculation models that assess the effect of the dispensing errors described would have on the final concentration of a compound after just two liquid delivery steps. Model 1 was designed to assess the effect that an inaccurate dispense of reagent into an accurate amount of buffer would have on reagent concentration. Model 2 assesses the maximum effect that inaccurate dispensing of both reagent and buffer would have on reagent concentration.
Liquid handlers can be inaccurate, but with tools and know-how, simple adjustments can ensure volume transfer accuracy, and confidence in assay results.

Red Medicine: Traditional Indigenous Rites of Birthing and Healing
By Patrisia Gonzales
Patrisia Gonzales addresses "Red Medicine" as a system of healing that includes birthing practices, dreaming, and purification rites to re-establish personal and social equilibrium. The book explores Indigenous medicine across North America, with a special emphasis on how Indigenous knowledge has endured and persisted among peoples with a legacy to Mexico. Gonzales combines her lived experience in Red Medicine as an herbalist and traditional birth attendant with in-depth research into oral traditions, storytelling, and the meanings of symbols to uncover how Indigenous knowledge endures over time. And she shows how this knowledge is now being reclaimed by Chicanos, Mexican Americans and Mexican Indigenous peoples.
For Gonzales, a central guiding force in Red Medicine is the principal of regeneration as it is manifested in Spiderwoman. Dating to Pre-Columbian times, the Mesoamerican Weaver/Spiderwoman--the guardian of birth, medicine, and purification rites such as the Nahua sweat bath--exemplifies the interconnected process of rebalancing that transpires throughout life in mental, spiritual and physical manifestations. Gonzales also explains how dreaming is a form of diagnosing in traditional Indigenous medicine and how Indigenous concepts of the body provide insight into healing various kinds of trauma.
Gonzales links pre-Columbian thought to contemporary healing practices by examining ancient symbols and their relation to current curative knowledges among Indigenous peoples. Red Medicine suggests that Indigenous healing systems can usefully point contemporary people back to ancestral teachings and help them reconnect to the dynamics of the natural world.

While street art has a rich history in terms the formation of the urban landscape, mainly through the appropriation of wall space, Sound Tossing offers a way to play with urban aesthetics through filling space with unique acoustic input. It provides new ways to add meaning to public spaces.
The project was inspired by so-called Shoe Tossing or Shoefiti, the practice of hanging shoes which have been tied together on overhead cables such as power or telephone lines. Sound Tossing operates in a similar way to the visual codes used in Shoe Tossing; speakers are connected via cables to audio components which function in this form of urban communication as "throwing tools".
A key area is the development and distribution of open source technologies for sound interventions in the context of street art. The Sound Tossing units offered include sound generators which operate with solar energy and motion sensors or timers as well as units that convert electromagnetic frequencies into acoustic signals. Some units are equipped with recording functionality and/or transmitters so they in essence become small pirate radio stations. Detailed assembly instructions and video demonstrations for each project are provided so they can easily be set up by anyone.
Sound Tossing is a resistance movement. It is aimed a countering the dominance of acoustic advertising and new sound security tools intended to prevent young people from congregating in specific areas such as in public places and outside shops. Sound Tossing is instead a subtle sound intervention. It impacts and alters the normal course of urban life while encouraging discussion of topics such as acoustic overstimulation and public well-being. Moreover, Sound Tossing increases public awareness of the acoustic environment.

What is orienteering? Orienteering is a competitive form of land navigation. It is for all ages and degrees of fitness and skill. It provides the suspense and excitement of a treasure hunt. The object of orienteering is to locate control points by using a map and compass to navigate through the woods. The courses may be as long as 10 km.
Orienteering began in Scandinavia in the nineteenth century. It was primarily a military event and was part of military training. It was not until 1919 that the modern version of orienteering was born in Sweden as a competitive sport. Ernst Killander, its creator, can be rightfully called the father of orienteering. In the early thirties, the sport received a technical boost with the invention of a new compass, more precise and faster to use. The Kjellstrom brothers, Bjorn and Alvan, and their friend, Brunnar Tillander, were responsible for this new compass. They were among the best Swedish orienteers of the thirties, with several individual championships among them. Orienteering was brought into the US in 1946 by Bjorn Kjellstrom.
Each orienteer is given a 1:50,000 topographic map with the various control points circled. Each point has a flag marker and a distinctive punch that is used to mark the scorecard. Competitive orienteering involves running from checkpoint to checkpoint. It is more demanding than road running, not only because of the terrain, but because the orienteer must constantly concentrate, make decisions, and keep track of the distance covered. Orienteering challenges both the mind and the body; however, the competitor's ability to think under pressure and make wise decisions is more important than speed or endurance.
F-3. THE COURSE
The orienteering area should be on terrain that is heavily wooded, preferably uninhabited, and difficult enough to suit different levels of competition. The area must be accessible to competitors and its use must be coordinated with appropriate terrain and range control offices.
a. The ideal map for an orienteering course is a multi-colored, accurate, large-scale topographic map. A topographic map is a graphic representation of selected man made and natural features of a part of the earth's surface plotted to a definite scale. The distinguishing characteristic of a topographic map is the portrayal of the shape and elevation of the terrain by contour lines.
b. For orienteering within the United States, large-scale topographic (topo) maps are available from the Defense Mapping Agency Hydrographic Topographic Center. The scale suitable for orienteering is 1:50,000 (DMA).
F-4. SETTING UP THE COURSE
The challenge for the course setter is to keep the course interesting, but never beyond the individual's or group's ability. General guidance is to select locations that are easily identifiable on the map and terrain, and accessible from several routes.
a. Those who set up the initial event should study a map for likely locations of control points and verification of the locations. Better yet, they should coordinate with an experienced competitor in selecting the course.
b. There are several forms of orienteering events. Some of the most common are route, line, cross-country, and score orienteering.
(1) Route Orienteering. This form can be used during the training phase and in advanced orienteering. In this type of event, a master or advanced competitor leads the group as they walk a route. The beginners trace the actual route walked on the ground on their maps. They circle the location of the different control points found along the walked route. When they finish, the maps are analyzed and compared. During training, time is not a factor. Another variation is when a course is laid out on the ground with markers for the competitor to follow. There is no master map, as the course is traced for the competitor by flags or markers. The winner of the event is the competitor who has successfully traced the route and accurately plotted the most control points on his map.
(2) Line Orienteering. At least five control points are used during this form of orienteering training. The competitor traces on his map a preselected route from a master map. The object is to walk the route shown on the map, circling the control points on the map as they are located on the ground (Figure F-1).
Figure F-1. Line orienteering.
(3) Cross-Country Orienteering. This is the most common type of orienteering competitions. It is sometimes called free or point orienteering and is considered to be the most competitive and intriguing of all events (Figure F-2). In this event, all competitors must visit the same controls in the same order. With the normal one-minute starting interval, it becomes a contest of route choice and physical skill. The winner is the contestant with the fastest time around the course.
Figure F-2. A cross-country orienteering map.
(a) After selecting the control points for the course, determine the start and finish locations. The last control should be near the finish. In describing each control's location, an eight-digit grid coordinate and a combination of two letters identifying the point (control code) should be included in each descriptive clue list that is normally given to each competitor at least two minutes before his start time.
(b) There are usually 6 to 12 control markers on the course in varying degrees of difficulty and distances apart so that there are no easy, direct routes. Instead, each competitor is faced with many choices of direct but difficult routes, or of indirect but easier routes. Each control's location is circled, and the order in which each is to be visited is clearly marked on the master map. The course may be a closed transverse with start and finish collocated, or the start and finish may be at different locations. The length of the course and difficulty of control placement varies with the competitors' degree of expertise. Regardless of the class of event, all competitors must indicate on their event cards proof of visiting the control markers. Inked stamps, coded letters, or punches are usually used to do this procedure.
||The same orienteering range may serve in both cross-country and score events. However, a separate set of competitor maps, master maps, and event cards are necessary.
(4) Score orienteering. In this event, the area chosen for the competition is blanketed with many control points (Figure F-3). The controls near the start/finish point (usually identical in this event) have a low point value, while those more distant or more difficult to locate have a high point value. (See Figure F-6 for a sample card.) This event requires the competitor to locate as many control markers as he can within the specified time (usually 90 minutes). Points are awarded for each control visited and deducted for exceeding the specified time. The competitor with the highest point score is the winner.
Figure F-3. A score orienteering map.
(a) Conducting a score event at the start is basically the same as the cross-country event. The competitor is given a map and an event card. The event card lists all the controls with their different point values. When released to the master map, the competitor finds the circles and numbers indicating the location of all the controls listed on his event card. He copies all the red circles on his map. Then he chooses any route he wishes to take in amassing the highest possible point score in the time available. The course is designed to ensure that there are more control points than can possibly be visited in the allotted time. Again, each control marker visited must be indicated on the event card.
(b) It is important for the competitor to take time initially to plot the most productive route. A good competitor may spend up to 6 minutes in the master map area while plotting the ideal route.
(c) There is no reward for returning early with time still available to find more points, so the good competitor must be able to coordinate time and distance with his ability in land navigation in running the course.
The same officials can be used at the start and finish. More officials or assistants can be used; the following material lists the minimum that can be used for a competition. They include the following:
a. At The Start.
(1) Course Organizer—Briefs the orienteers in the assembly area, issues event cards and maps, and calls orienteers forward to start individually.
(2) Recorder—Records orienteer's name and start time on recorder's sheet, checks orienteer's name and start number on his event card, and issues any last-minute instructions.
(3) Timer—Controls the master clock and releases the orienteers across the start line at their start time (usually at one-minute intervals) to the master map area.
b. At The Finish.
(1) Timer—Records finish time of each orienteer on the orienteer's event card and passes card to recorder.
(2) Recorder—Records finish time of each orienteer on the orienteer's event card and passes card to recorder.
(3) Course Organizer—Verifies correctness of names, finish times, and final score; posts orienteers' positions on results board; and accounts for all orienteers at the end of event.
F-6. START/FINISH AREA
The layout of the start/finish areas for orienteering events is basically the same for all forms.
a. Assembly Area. This is where orienteers register and receive instructions, maps, event cards, and start numbers. They may also change into their orienteering clothes if facilities are available, study their maps, and fill out their event cards here. Sanitation facilities should be

From Code to Cloud Azure Migration Strategies for Blockchain Developers
From Code to Cloud Azure Migration Strategies for Blockchain Developers
Rate this post
Blockchain technology has completely changed how our transactions are done and how we store data and build trust. Due to the inherent decentralization and immutability of Blockchain, it is used in finance, healthcare, supply chain management, and other sectors. The global Blockchain market is predicted to hit $3.1 trillion by 2030, demonstrating the high demand for and recognition of its advantages.
For blockchain developers, it is crucial to provide a smooth interface for their applications that will allow the technology to realize its full potential. This is the area where Azure Migration Strategies become essential. By using Azure, the platform powered by Microsoft's cloud, developers can simplify their operations, fortify their security, and grow their Blockchain applications effortlessly. In this blog, we'll discover Azure Migration Strategies and how they can be applied to the needs of Blockchain developers.
Understanding Azure Migration Strategies
Azure Migration Strategies is a group of methodologies, tools, and services offered by Microsoft Azure that facilitates the migration of applications and workloads to the cloud. These strategies are the Blockchain developers' main feature: they can use the scalability, security, and cost-efficiency of the cloud to improve the Blockchain applications. Through the migration to Azure, developers can move beyond the issues of on-premises infrastructure, release new features, and speed up innovation in the development of Blockchain.
Why Azure Migration Is the Best Way For Blockchain Developers?
Azure Migration Strategies is a way for developers to upgrade their apps, simplify operations, and utilize the full power of Blockchain in the cloud, which in the end will be beneficial for their business growth and differentiation.
Comprehensive Support For A Wide Range Of Workloads
This is essential to Azure Migration Strategies, especially for Blockchain developers wanting to move their applications to the cloud. Azure delivers all the tools, services, and frameworks that can support any kind of Blockchain workload. Therefore, the migration process is highly optimized and smooth.
Let's take a case where the Blockchain developer will be employed to build a permissioned Blockchain using Hyperledger Fabric. The Azure Migration Strategies is a tool that enables the migration of the Hyperledger Fabric network to the Azure Blockchain Service. Azure provides pre-configured templates, deployment guides, and DevOps tooling tailored for Hyperledger Fabric; hence, the migration process becomes easy, and disruptions can be minimized.
Azure's support is not limited to Blockchain platforms, but it provides solutions for various business cases in different industries. Whatever kind of application developers are building to offer financial services, supply chain solutions or identity management on Blockchain, Azure has specialized services and guidance to meet their unique demands.
The Azure hybrid cloud feature gives room for blockchain developers who are not yet ready to deploy the technology for full-scale cloud migration. An instance of this is the utilization of Azure Stack to implement Blockchain nodes at the edge for low latency cases and Azure Arc to handle Blockchain environments distributed on-premises and cloud infrastructure.
Integration to the Blockchain Frameworks And Tools
In Azure, simplicity is a crucial element that simplifies the migration process for Blockchain developers and ensures compatibility and better productivity. Through Azure, developers can use its sophisticated support for popular Blockchain frameworks and development tools. Thus, they can rely on their current knowledge and infrastructure as they migrate to the cloud.
Let's take the example of a Blockchain developer who works with Ethereum; an Ethereum platform is one of the most popular and widely used platforms to build decentralized applications (DApps). Azure gives dedicated services like the Azure Blockchain Service, which is straightforward to link up with Ethereum and other frameworks like Quorum. Such integration enables developers to deploy, manage, and scale Ethereum nodes and DApps on Azure without effort, leveraging known tools and APIs.
Azure can also support other famous Blockchain frameworks, such as Hyperledger Fabric and Corda, providing specialized services and tooling that comply with the requirements of each framework. Along these lines, Azure Blockchain Workbench is a complete solution for building and deploying Hyperledger Fabric-based Blockchain applications. On the other hand, Azure Blockchain Development Kit helps to simplify integration with Corda networks.
Hybrid Cloud Flexibility
The flexibility of the hybrid cloud, which means Azure can combine on-premises infrastructure with cloud-based resources, gives a developer a flexible approach to deploying and managing Blockchain applications. Such a hybrid approach provides a trade-off between the on-premises systems that give the developers control and the cloud-based systems that offer scalability and agility.
Some sensitive information or regulatory restrictions may require some application parts to stay on-premises to ensure compliance and control. Besides, the institution can also use cloud computing to cope with the peak times when there are many transactions to process.
Azure's hybrid cloud model enables the institution to place the main components of their Blockchain application on-premises and use Azure Cloud services, including Azure Blockchain Service or Azure Kubernetes Service (AKS), as extra power and scalability as is needed.
Robust Data Management and Analytics
Data management and analytics are two of the most crucial functions that Blockchain developers use to maximize the benefits of their applications. Azure provides a suite of services to satisfy these needs. Think of Azure Cosmos DB, a globe-encompassing, multi-model database service.
The data storage capability of this service allows blockchain developers to handle and store various data types connected to transactions, smart contracts, and user identities. Cosmos DB offers the advantage of being global and low-latency, by which developers can provide data replication across different regions. This ensures that the Blockchain data is highly available and tolerant of faults.
In addition, Azure SQL Database is a managed relational database service that can store all structured data (related to Blockchain transactions and user profiles). Developers can do much more with SQL Database, run complex queries, do analytics, and generate actionable insights from Blockchain data as it becomes easier.
For example, the built-in analytics capabilities of SQL Database can help users identify transaction patterns, spot anomalies, and improve performance for Blockchain applications so that developers can maximize their efficiency.
Wrap-Up
Developers can easily move their Blockchain applications to the cloud using Azure's various Azure application modernization services and Azure consulting. This will open new doors for scalability, security, and cost-effectiveness that have never been seen before. The Azure Blockchain development is bright, full of promising prospects, and has an endless universe of possibilities in the future.

With the expected rise in space tourism, we think that there may become a time when we're building a Moon Hotel, but we're a bit stuck on what we think it might look like. We'd love to see your pupils' ideas on what a Moon Hotel could look like, what weird and wacky features they might include and how they will overcome the environmental issues on the Moon.
Using the list of facts about the Moon below and children's own knowledge and research, we'd like them to design a poster or pamphlet. We'd like pupils to think about food, water, air, gravity, and how people will get there. How would it be different from hotels on earth? What would people need to survive? How would they get around? What cool things would there be inside for people to do?
Children must draw a poster or write a pamphlet explaining their hotel, the features they have added to it and why they have chosen to do certain things e.g., build a greenhouse to grow food.
The poster or pamphlet should be aimed at attracting people to visit your Moon Hotel by advertising the features of the establishment.
Facts About The Moon
1. The Moon orbits the Earth and is the only natural satellite
2. The same side always faces the Earth, meaning we have never seen the far side from our planet (although there are pictures taken from satellites that have gone all the way around). This is called tidal-locking and happens because the Moons rotation is the same speed as the Earths.
3. The temperature is -233°C to +123°C
4. The Moon's orbit controls the Earths tides
5. The Moon is moving away from the Earth at a speed of 3.8cm a year
6. You would weigh less on the surface of the Moon because it has less gravity and would also mean lighter objects might float away into space
7. There is no atmosphere on the Moon and therefore no protection from outer-space or things like the suns rays, comets, and high winds
8. There are many moonquakes, causing fractures and ruptures that happen every week
9. It takes 3 days in a spaceship to get to the Moon
10. There are sources of oxygen on the Moon, but the lack of atmosphere means that there is no way of keeping it near the surface (like it is on Earth) meaning you can't breathe the air
Lower KS2: Draw a poster to attract people to visit a new hotel on the Moon
Upper KS2: Design a pamphlet to explain a new hotel on the Moon and attract people to visit
Start date: 26th March 2019
Close date: 14th June 2019
Winners announced: 28th June 2019
What we're looking for in the winning entry: Clear link between the environment on the Moon and the hotel features, i.e. a 0-gravity room for entertainment, a greenhouse to grow food, cylinders to make water, oxygen pumps etc.
Clear descriptions of their ideas, explaining why they have chosen certain things and what the purpose of everything is.
Extra points to children who consider the journey to the Moon.
There will be only one winner from both upper and lower KS2.
The prize for pupils: Selection of goodies from the European Space Agency and a selection of activities and investigations they can do at home

1 kHz fixed Frequency Oscillator
The CH705 generates a fixed 1kHz tone at a fixed and stable output level +6dBu. The output level can be internally aligned within the range of -10dBu to +15dBu.
The Vienna bridges 1 kHz Oscillator has distortion attenuation of at least 60 dB and a balanced and floating output with very low internal resistance. With a resistance load of 200 ohms the level fluctuation is less than ±0.2 dB. The 1 kHz oscillator can thereby be used as a central level audio generator, because the level remains constant independent of the number of output feeds.
The 1 kHz oscillator has three outputs; output 1 always sends a signal when the switch OSC-ON is turned on, output 2 sends a signal if, in addition, the switch OUTPUT-ON is operated, and output 3 sends a -60dBu or -9dB/-3dBu adjusted signal.
The CH705 1 kHz oscillator is a standard V700 module and fits into standard mounting frames.

The Koninklijke Nederlandse Politiehond Vereniging (KNPV) is a dog sport originating in Holland that uses a number of exercises in an attempt to mimic situations encountered by police k9 units. One such exercise is centered around a search for small articles.
The KNPV small articles search takes place in a square section of grassy field. Three small objects, such as a key, a ring, a bullet casing, or a coin, are placed on the field. The dog then has 10 minutes to search the field and retrieve the objects. The handler is permitted to give basic commands instructing the dog to search, stay or release the retrieved object. A retrieval time of under 3 minutes is required to obtain a perfect score, while the dog is also graded on general obedience, the manner in which it searches the field, and how it handles the objects during the retrieval stage.
The intent of this exercise is to train the dog to act in a manner that mimics a police search for evidence. Unfortunately, the way this exercise is performed by the KNPV presents a number of problems when compared against what would be required of a search conducted by actual police forces. One of the biggest problems is that the dog is trained to mouth the object, pick it up and bring it back to the handler. In a real police search, investigators wear latex gloves to avoid disturbing the evidence any more than absolutely necessary. To have the dog mouth a piece of evidence might completely ruin it. The correct action for the dog to take would be to indicate passively by sitting next to the found article. Secondly, because KNPV is a sport, the exercises are performed with specific regulations concerning the search area. During a search, an officer can almost never rely on evidence being simply dropped in a perfectly square patch of grassy field.
The most important thing to remember is that KNPV, like all other dog sports, is just a sport. Police dogs, protection dogs and guard dogs alike need to be trained to handle real situations from the very beginning. Training for sport just isn't good enough for work in the real world.

UNCOVERING SCHOOL CULTURE: A STUDY OF JOINT EXPLORATION THROUGH ITERATIVE INTERVIEWING
The concept of organizational culture has been receiving a growing amount of attention in education as well as in business. In this emphasis devising a means for uncovering culture becomes a special concern. Edgar H. Schein developed a definition of culture and then designed a method for uncovering it. Schein defined culture as a pattern of basic assumptions which focuses on external adaptation and internal integration issues. An example of an external adaptation issue deals with determining the organization's main purpose. An example of an internal integration issue is how power and status are obtained. The assumptions about the external adaptation and internal integration issues become taken-for-granted and are used to orient new members to their work and to the organization. By uncovering organizational culture, some important information can be learned and understood, for example, the purpose of the organization, the ways the purpose is achieved, and personal relations within the organization. If the personnel of an organization learn its culture, they then can plan improvements. The major question addressed in this research study was the following: Is Schein's method of uncovering organizational culture suitable for uncovering a portion of the culture of a Lutheran elementary school? Schein's 10-step method of uncovering culture--joint exploration through iterative interviewing--utilizes repetitive personal interviews as its main means of obtaining cultural information. In addition, on-site observation is used to gather data. Schein used his method successfully as he uncovered the culture of several business organizations. The question than arose whether school culture could be uncovered by replicating Schein's 10-step method. The purpose, then, of this research study was to test the suitability of Schein's method for uncovering culture in three Lutheran elementary schools. Schein's 10-step method was replicated in three school settings. By using Schein's method, a portion of the culture of those three schools was uncovered. The study demonstrated that Schein's method was suitable for uncovering culture in three Lutheran elementary schools.

A Qlik Sense Generic Object can also be used to list objects in the Qlik Sense app to which it belongs. You can use it to list things like:
 - fields
 - dimensions
 - measures
 - bookmarks
 - snapshots
 - media (that is images controlled by Qlik Sense)
 - sheets
 - master objects
 - variables
 - stories
The javascript APIs provide the app.getList method, which is a wrapper that helps you get theses lists. It will create a session object for you with the list you are requesting, get that actual data in the list and call your callback function once the data is available.
List are live – your callbacks might be called several times
Just like with other Generic Objects the data might be invalidated. If you are using the javascript APIs it will then be automatically revalidated and your callback function will be called again, so you should be prepared that your callback might be called multiple times. But unlike the Hypercube and List Object the lists are not affected by the users selections. Instead they will be invalidated when the underlying data changes:
 - if the user adds a bookmark, you will get a new bookmarklist
 - if the user adds a measure, you will get a new measurelist
 - if the user adds a dimension, you will get a new dimensionlist
 - etc….
Configure the data you get in your list
The data you get in your lists is configurable. If you use the API method, you will get a default set of fields for each item in the list, but you can set the list up to suite your needs.
As an example, if you use the api method getList('measure', callback), you will get a list where records look like this:
The first and second part, qInfo and qMeta, will always be there. They contain the id to use when refering to this measure and title and description use ful in a list of measures. The third part however, qData, is configurable. The default configuration just gives you tags and title one more time, but if you instead want more data about the measure, you can use your own measure list definition like this:
Under qData you provide your own mapping of the properties you want. In this case I have just specified that I want everything under qMeasure included. You can also specify individual fields.
And get output that includes more data for the measures:
And the same goes for the other lists, you can supply your own definitions and get more data included.
SWhile the HyperCube is the main object for calculating data the ListboxObject is a way to list available values for a field. Its the object behind the listboxes in the Filter Panel. It is also the object used for the listboxes that are created when you click on a field in the selection toolbar.
An example setup from the horizontal listbox extension example, included with the Qlik Sense installation:
This contains defaults for most of the parameters, except the actual field, which the user selects in the property panel, which looks like this:
As you can see the Listbox has either a predefined measure from the library, in which case qListObjectDef.qLibraryId will contain the id of the measure (some UID string) or it has a field name, which will be in the array qListObjectDef.qDef.qFieldDefs at the first position. You don't really have to bother about which one the user selects to use, the ListboxObject will work the same anyhow.
Frequencies and sort order
There are also some other properties in the ListboxObject that are well known to QlikView users. The frequence mode gives you some additional info on the frequency of the respective values in the ListboxObject. Look to horizontal listbox extension for an example. There is also the qSortCriterias array, which allows you to specify the sort order. The default is to have the selected values first, but you might want to for example keep months order from January to December irrespective of which month is selected.
Mashup editor – even more properties
Like with the Hypercube, you can also build a ListboxObject in the mashup editor. The tool to do this looks like this:
As you can see, you also get the option to include expressions in your listbox, usable if you want to make some calculations for each value in the list. The mashup editor will create a ListboxObject for you like this:
The expressions are added to the ListboxObject in the qExpressions array. In this example I have used predefined measures, but you can also use measures defined in the actual listbox object. The mashup editor includes a expression editor (actually the same used in the Qlik Sense client) to help you with this.

text: In this paper, a new multiobjective optimization approach is proposed for the selection of the optimal values for cutting conditions in the face milling of cobalt-based alloys. This approach aims to handle the possible manufacturing errors in the design stage. These errors are taken into consideration as a change in design parameter, and the design most robust to change is selected as the optimum design. Experiments on a cobalt-based superalloy were performed to investigate the effect of cutting speed, feed rate and cutting depth on the cutting forces under dry conditions. Material removal rate values were also obtained. Minimizing cutting forces and maximizing the material removal were considered as objectives. It is believed that the used method provides a robust way of looking at the optimum parameter selection problems.

Vinge is currently Denmark's largest development area, and Henning Larsen Architects + TREDJE NATUR (Third Nature) have together with MOE and RPA developed the new station and a huge central area that is to contain 183.000 m2 of new buildings (2 million squarefeet).The ambition is to create a vibrant urban center, with comparable density to that of central Copenhagen, while also offering green, sustainable and recreative elements that are integrated parts of the VingeCity DNA.
Vinge's identity follows the values and characteristics that already exist in the Danish countryside, located close to the Roskilde Fjord on the outskirts of Copenhagen. The hilly terrain and beautiful nature create a direct interaction with the infrastructure network that outlines of the city.
Running centrally through the station is The Green Heart, a landscape corridor that crosses Vinge from North to South. The train station becomes the center for the city, with the neighboring buildings offering a varied spatial hierarchy and intimacy around the urban disc. The buildings house a range of functions, including residential, commercial, public institutions, private companies and retailers. The Green Heart integrates the existing natural elements
The natural focal point of the master plan is the S-train station and the circular urban space (also known as the Landscape Bridge). Vinge's station is placed naturally, at the intersection of The Green Heart and the tracks. The station is the focal point of the city's dense and lively center, where users experience a mix of city and marshland on one side, with forest on the other.

Optimization of Stochastic Strategies for Spatially Inhomogeneous Robot Swarms: A Case Study in Commercial Pollination

CitationBerman, Spring, Radhika Nagpal, and Ádám Halász. 2011. Optimization of stochastic strategies for spatially inhomogeneous robot swarms: a case study in commercial pollination. In Proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS'11): September 25-30, San Francisco, CA, 3923-3930. Los Alamitos, Calif: IEEE Computer Society Press.
AbstractWe present a scalable approach to optimizing robot control policies for a target collective behavior in a spatially inhomogeneous robotic swarm. The approach can incorporate robot feedback to maintain system performance in an unknown environmental ﬂow ﬁeld. We consider systems in which the robots follow both deterministic and random motion and transition stochastically between tasks. Our methodology is based on an abstraction of the swarm to a macroscopic continuous model, whose dimensionality is independent of the population size, that describes the expected time evolution of swarm subpopulations over a discretization of the environment. We incorporate this model into a stochastic optimization method and map the optimized model parameters onto the robot motion and task transition control policies to achieve a desired global objective. We illustrate our methodology with a scenario in which the behaviors of a swarm of robotic bees are optimized for both uniform and nonuniform pollination of a blueberry ﬁeld, including in the presence of an unknown wind.

Did you know that driving at 70 km/h in a 60-km/h zone puts a driver at greater risk for a collision involving injury than does driving with a blood alcohol level of.08 g/100ml? The evidence says that the relative risk is 4.2 for the first practice (70 km/h in a 60-km/h zone), compared to 3.2 for the other (.08% alcohol). (Road Speed, p. 13)
In this document you will find a substantial review of the evidence on speeding. Besides presenting data such as those found above, the document points out that we must consider the phenomenon of road speed within a social context. Despite the disturbing realities about speeding, it is seen as a relatively minor type of offense, not comparable ot other, more serious illegal behavour. In addition, it is not just the less frequent instances of extreme speeding which pose a problem. The more common form of road speed (such as travelling at 70 km/h in a 60 zone) is shown to be a significant risk.
This scientific review, produced by the Direction développement des individus et des communautés of the INSPQ (the Institut national de santé publique du Québec - Quebec's public health institute), sets out to:
- Show the dangers to the public caused by road speed, including injuries, pollution, and less pedestrian and cyclist-friendly public spaces;
- Show how road speed reduces drivers' ability to avoid collisions;
- Review the current scientific evidence for the effectiveness of various measures aimed at reducing speed; and

1 Benefit of growing high pressure aeroponics is aeration. Air Atomized Aeroponics can do things that no other hydroponic growing system can replicate. Setting environmental conditions with pin point precision, and injecting oxygen directly to the root chamber.
True Aeroponics ( TAG ) is actually less complicated than the more popular HPA or high pressure aeroponics. To DIY Aeroponics just take a bit a patience and time to assemble your own aeroponic system.
Two opposing hydroponic methods which are probably the most popular are DWC Deep Water Culture and HPA High Pressure Aeroponics. DWC utilizes water as its medium supplementing air to sustain the plant. If you ever ran a DWC system you will know the more air you can circulate into the system the better health of the plant. Whereas HPA uses air as its medium and supplements water to sustain the plant. The downside to this method is using the high pressure water spray nozzles is that as the root system develops. The nozzles end up spraying the exterior of the root system.
Air Atomizing Aero can penetrate the interior of the root system. Every blast of the feed cycle injecting fresh air and nutrients directly to the roots. As with many things… Surface Area is very important. In plants there are 2 main root types the Tap Roots & Feed Roots,. Air Atomized Aeroponics develops an insane amount of feed roots to maximize its surface area.
This being my first set up with AAA and figuring out how to build and run this system. I've encountered a few set backs, one being nearly killing the plant. One thing I know without a doubt is had I used DWC, RDWC, HPA, LPA, Ebb & Flow/Flood & Drain, Even Top Feed, this plant would not have survived. Top Feed is actually they back up system I created in order to help sustain this plant. Top Feed is actually what caused the plant to develop root rot.
Hope you guys decide to step up and go Aero!

Does Love Survive Loss?
Auden and Larkin each wrote powerful lines about love—and then had grave doubts about them. Why?
Photograph by Tom Oates.
"Amor vincit omnia," Love conquers all. Or so Virgil wrote. But does it? Does love survive dissolution of the lovers? And if so, where exactly would it be, where does all that lost love survive?
I was prompted to revisit these ancient questions anew by a long footnote about a single line in the new Complete Poems edition of Philip Larkin's poetry. The footnote refers to "An Arundel Tomb"—widely regarded as one of Larkin's finest poems—and contains a provocative remark about that the poem's celebrated, controversial, closing line, the one about the true nature of immortality:
"What will survive of us is love."
The line is so uncharacteristic of Larkin, one of the most relentlessly downbeat poets in modern literature, that it's almost shocking in its apparently uncomplicated affirmation. You can barely believe it. In that footnote I mentioned there are quotes from Larkin suggesting he could barely believe it either.
No offense to the Beatles, but on first reading, Larkin's line sounds like "And in the end, the love you take/ Is equal to the love you make," that saccharine reduction of love's transcendence to algebra.
Thinking about the survival of love in the context of Larkin's poem, I suddenly felt the parallel with another controversial line, this one from W.H. Auden. A quarter-century or so before Larkin, Auden originally wrote, in the closing line of the penultimate stanza of perhaps his most celebrated poem, "September 1, 1939":
"We must love one another or die."
These two lines—Larkin's "What will survive of us is love" and Auden's "We must love one another or die"—may be the most well-known lines of poetry about love written in the past century. But what's remarkable about them both is that the poets who wrote them agonized over them, were conflicted and critical of their own lines. Both Larkin and Auden eventually tried to distance themselves from their original unmediated utterances.
Indeed that extended footnote in the new Larkin edition eventually led me to rethink it all—Larkin, Auden, love, love poetry—even footnotes. Footnotes? Sometimes with poetry you can know too much about what the poet thinks. After he publishes a poem, it's not his or hers anymore, you know? Though that doesn't stop some of the poets—or their loving anthologists—from trying to control how you construe the poems (or at least prevent egregious misconstruals) via scholarly footnotes. But do poets always know the truth of what they've wrought?
Auden rethought his line—"We must love one another or die"—almost immediately. Indeed he turned violently against it, tried to ban, or vanish it. Called the poem in which it appeared "trash." Said he "loathed" it. And yet the line still persists in a limbo of literary erasures that don't completely efface the original. And now we learn Larkin had doubts about his love-affirming line.
What is going on here? Where is the love for love, guys?
Larkin and Auden are perhaps the two pre-eminent English-language poets of the past century, successors to Eliot and Yeats. For Americans less familiar with Larkin, I'm not going to get into an argument here over the poets' pre-eminence. Yes, there are American contenders, Lowell, Bishop, Hart Crane. Even Nabokov on the strength of "Pale Fire" alone. But Larkin and Auden are frequently paired as poets without peers. (I know it's unseemly to talk in these horse-racy terms, but have you noticed the way Larkin appears to have overtaken Auden—and virtually all other moderns—in critical estimation of late?)
Here in America Larkin has previously been most well-known for his famous opening line "They fuck you up/ your mum and dad." That line and Larkin's doggerel-like verse about how "Sexual intercourse began in 1963... / Between the end of the Chatterley ban/ and the Beatles first LP" have given many casual American non-readers of poetry the misleading impression that Larkin was a cheeky writer of light verse. But just one exposure to his "Aubade" or "The Whitsun Weddings," "The High Window" or the poem with the controversial line about love—"An Arundel Tomb"—will knock you flat with the weightiness of the words, their fierce and sorrowful, yet somehow self-effacing intensity. They make you understand why "Larkinesque"—denoting a devastating yet somehow vibrant, self-revelatory, self-effacing melancholy—has become a kind of household word in households where poetry is still read.
Which is why that one line about love from "An Arundel Tomb" has always stood out, provoked questions. It seemed, in isolation, so un-Larkinesque. Was it an anomalous moment of uplifting affirmation, or was the line, taken out of context, being misread?
In a graveyard the speaker stumbles on the 14th-century tomb of the Earl of Arundel and his wife. In the age-blurred, partially eroded tomb carving, the Earl is fully dressed in armor from head to toe. Except for one thing: The speaker notes that in the carving the Earl has removed the armed gauntlet from one hand. (Larkin got the hand wrong—on the real tomb, it was the right-handed gauntlet not the left. Thank you, footnote.)
The point is that the mailed glove is off so he can clasp, skin to skin, the hand of his wife, as if they were joined forever by love in their journey to death. Joined, the poet implies, until the ravages of time blur and erase them from recognition as they have already been erased from life. Joined even though the purported loving jointure may be mere stone-carver's fantasy.
Here is how Larkin puts it in the poem:
"One sees with a sharp tender shock" the handholding gesture. "Sharp tender shock"!—one could write a book about that phrase.
The remaining five verses are devoted to the speaker's vexed examination of the image and his sharp tender shocked reaction to it. The speaker reflects on the fact that the joined hands were probably the sculptor's idea, suggesting a faithful love that may be merely "faithfulness in effigy"—an image rather than the lived reality of fidelity. So that finally "only an attitude remains" and "Time has transfigured them into Untruth...."
And yet in the final lines he says of this attitude:
Their "stone fidelity" has come to prove:
"Our almost-instinct almost true:
What will survive of us is love."
I feel a sharp tender shock every time I read that line. It's one that attained a certain wider degree of attention when Anthony Lane, the witty—and rarely sentimental—New Yorker film critic, cited it in a beautiful essay he wrote in the immediate aftermath of 9/11. He related Larkin's line to the image of the two people who jumped to their death from the burning towers, hand in hand, like the figures on Larkin's Arundel tomb.
"What will survive of us is love."
All alone, extracted from the poem, the line has the feel of an unmediated affirmation uncharacteristic of Larkin (or Lane). Let's face it, it sounds more like Oprah (not that there's anything wrong with that). Of course, there's more nuance and depth—and irony—to it when you consider it in context. But before we really dig into Larkin's unexpected Hallmark moment—and the footnote that complicates our view of it— let me first say a little more about the eerily not-quite-parallel case of W.H. Auden's famous line about love, because its tormented fate at the author's own hands may foreshadow—maybe even have caused—what we now know are Larkin's second thoughts about "what will survive of us is love."
Auden's line—and his second thoughts about it—invite questions about what we talk about when we talk about this kind of love. Not just mere perishable personal romantic love, but also the kind of numinous transfigured, impersonal universal love that embraces us all, survives like a holy ghost, survives like smoke from a High-Church censer ascending to heaven from the mortal bodies it inspirited.
Auden's more famous line about love (and death) refers at first glance to the title date of his poem "September 1, 1939," the date, of course, of the Nazi invasion of Poland that began the slaughter of the Second World War. It's the poem that opens:
Later lines from this despairing poem that has given birth to half a dozen book titles such as "The Haunted Wood" and "The Psychopathic God" and several aphorisms that now sound like old saws: "Those to whom evil is done/ Do evil in return." (This last was Auden's explanation for Hitler, the "psychopathic god" himself.)
And yet it is a poem whose original version climaxed with the line, "We must love one another or die."
A line that was also invoked after 9/11, as a consolatory uplift-inspiring sentiment that supposedly turned that tragedy into a "teachable moment." A line that has even more fatally, gratingly become

HUNG KINGS' COMMEMORATION DAY - Back to The Roots of Our Cultural Values
On Saturday morning March 27, CIS students have visited the Hung Kings Temple at the History Ethnic and Cultural Park (district 9) with over 30 students and teachers from the Saturday Vietnamese Program onboard. Following the Hung Kings Temple, impressive performance, and others, students have been able to engage in a valuable learning experience. During the journey to the Hung Kings Temple, the students had the opportunity to participate in various activities and engage in a valuable learning experience.
Students were listening to a presentation at Hung King Temple
Here, they were able to expand their understanding of their origin as well as learn about the great contributions of the Hung Kings, accompanied by informative lectures. Also, there is an enormous artwork depicting the material and spiritual life of the residents in Van Lang's era, and 33 stones representing the 33 islands of the Truong Sa archipelago, which is a reminder of the awareness of the sea and island sovereignty.
Designing historical Hung Vuong period attire
Following the impressive performance, students soon got to shaping "bánh giày", which are round, white glutinous rice cakes, to recreate the traditional scene of hand pounding rice in the exploration of the 2875-258 BC Van Lang lifestyle
Students glutinous with rice and make bánh giày
Finish cooking of the Hung Vuong dynasty
The succeeding culture-themed games, including Cheraw dance and tug of war, kept spirits high until the end. By allowing students to interact with a part of Vietnam's history, these activities boosted their appreciation for Vietnamese tradition and culture, specifically during the Hung Vuong period.
Cheraw dance
"I can feel the value of Vietnamese history and our country's soul through each unique painting and ancient artifacts. That's what I want to learn and cultivate. I will bring my filial spirit to discover Vietnamese people's cultural values and beauty wherever I go to continue enriching my understanding. It is also luggage for me to bring in my future journey to a new horizon." (Minh Anh, Grade 11)
 At the end of the trip, students took a photo together
All journeys leave behind an unforgettable trace, and those aiming to instigate experience and newfound knowledge surrounding cultural values especially so. This occasion brings meaning and memorable experiences, particularly the students in grade 11 of CIS.

Folquet de Marseilla
Folquet de Marseilla (c._PHONE_) was a merchant and troubadour before joining the clergy. Joining a Cistercian monastery, he became Bishop of Toulouse in 1205. He was a personal friend of St Dominic and helped found the Dominican order with him. Despite being placed in Paradise by Dante Alighieri, Folquet seems to have been particularly brutal in persecuting heretics during the Albigensian Crusade.
Folquet composed the songs that he was later to utterly reject between 1180 and 1195. His nineteen songs, of which thirteen melodies remain, are typified by intricate poetic structure.

Surveys of the water chemistry of the River Team were carried out from April to July 1979 in order to establish the extent of organic and metal pollution in the river. Selected aquatic bryophytes and algae were analysed to determine the possibility of using plant material as a means of monitoring zinc pollution. The possibility was investigated that different enrichment ratios in populations of Stigeoclonium tenue might be related to differences in tolerance to zinc found in the parellel study by C.S.

What are the real procedural costs of bariatric surgery? A systematic literature review of published cost analyses
Doble B., Wordsworth S., Rogers CA., Welbourne R., Byrne J., Blazeby JM.
This review aims to evaluate the current literature on the procedural costs of bariatric surgery for the treatment of severe obesity. Using a published framework for the conduct of micro-costing studies for surgical interventions, existing cost estimates from the literature are assessed for their accuracy, reliability and comprehensiveness based on their consideration of seven 'important' cost components. MEDLINE, PubMed, key journals and reference lists of included studies were searched up to January 2017. Eligible studies had to report per-case, total procedural costs for any type of bariatric surgery broken down into two or more individual cost components. A total of 998 citations were screened, of which 13 studies were included for analysis. Included studies were mainly conducted from a US hospital perspective, assessed either gastric bypass or adjustable gastric banding procedures and considered a range of different cost components. The mean total procedural costs for all included studies was US$14,389 (range, US$7423 to US$33,541). No study considered all of the recommended 'important' cost components and estimation methods were poorly reported. The accuracy, reliability and comprehensiveness of the existing cost estimates are, therefore, questionable. There is a need for a comparative cost analysis of the different approaches to bariatric surgery, with the most appropriate costing approach identified to be micro-costing methods. Such an analysis will not only be useful in estimating the relative cost-effectiveness of different surgeries but will also ensure appropriate reimbursement and budgeting by healthcare payers to ensure barriers to access this effective treatment by severely obese patients are minimised.

Tumors of the External Ear
Tumors of the ear can be benign or malignant. They can occur on the external ear, or in the ear canal, the middle ear or inner ear. Tumors in different areas of the ear behave differently. Thus, it is necessary to describe tumors based on their site of occurrence, as well as their behavior and treatment.
Tumors of the External Ear Canal
The external ear canal begins at the opening of the cup-shaped portion (concha) of the ear and extends downward to the ear drum. Tumors that occur in the ear canal can be benign or malignant. Malignant tumors of the external ear canal are very serious. Immediate biopsy of any suspicious lesion in the external ear canal should be performed immediately.
Causes of Ear Cancer
The exact cause of ear cancer is not known. Individuals with history of chronic ear infections (>10 years) are at a higher risk for developing ear cancer.

Then we moved to Alwar fort know as bala fort also.
The Alwar Fort is nestled in a steep hill that is 300 meters above the city. The magnificent fort is a great landmark of the Alwar. The fort has a lot of historical significance. It was built before the Mughal period in the 16th century. Moreover, it is also believed that Babur once came to the fort in order to dodge his enemies. History associated to the fort also reveals that the fort was taken over by Rana Pratap Singh in 1775. However, there is no consensus among historians to draw a conclusion to this. It is also believed that Nikumbh Rajput built the palace in 928 A.D. Hence, the history of fort draws a lot of confusion and curiosity. This curiosity often acts as an appeal for the tourists.
The magnificent Alwar Fort stretches across 5 kilometers from North to South and is located at a height of 305 meters above the main city. Various architectural features like the 15 large and 51 small towers add a lot of beauty to the fort. There are also beautiful gates and each of the gates bear different names. The various names of the entry points of the fort are Chand Pol Kishan Pol, Laxman Pol, Jai Pol and Suraj Fort. Looking at the various architectural features of the fort, you will surely wonder about the architectural excellence of craftsmen of that era
