child process will run all the checks and record the results in $RESULTFILE (default: /var/run/nhc.status). The next time nhc is executed, just before forking off the child process (which will again run the checks in the background), it will load the results from $RESULTFILE from the last execution. Once the child process has been spawned, it will then return the previous results to its caller.
The advantage of detached mode is that any hangs or long-running commands which occur in the checks will not cause the resource manager daemon (e.g., pbs_mom) to block. Sites that use home-grown health check scripts often use a similar technique for this very reason -- it's non-blocking.
However, a word of caution: if a detached-mode nhc encounters a failure, it won't get acted upon until the next execution. So let's say you have NHC configured to only on job start and job end. Let's further suppose that the /tmp filesystem encounters an error and gets remounted read-only at some point after the completion of the last job and that you have check_fs_mount_rw /tmp in your nhc.conf. In normal mode, when a new job tries to start, nhc will detect the read-only mount on job start and will take the node out of service before the job is allowed to begin executing on the node. In detached mode, however, since nhc has not been run in the meantime, and the previous run was successful, nhc will return success and allow the job to start before the error condition is noticed!
For this reason, when using detached mode, periodic checks are HIGHLY recommended. This will not completely prevent the above scenario, but it will drastically reduce the odds of it occurring. Users of detached mode, as with any similar method of delayed reporting, must be aware of and accept this caveat in exchange for the benefits of the more-fully-non-blocking behavior.
Built-in Checks
In the documentation below, parameters surrounded by square brackets ([like this]) are optional. All others are required.
The LBNL Node Health Check distribution supplies the following checks:
check_cmd_output
check_cmd_output [-t timeout] [-r retval] [-m match [...]] { -e 'command [arg1 [...]]' | command [arg1 [...]] }
check_cmd_output executes a command and compares each line of its output against any _mstr_s (match strings) passed in. If any positive match is not found in the command output, or if any negative match is found, the check fails. The check also fails if the exit status of command does not match retval (if supplied) or if the command fails to complete within timeout seconds (default 5). Options to this check are as follows:
Check Option Purpose
-ecommand Execute command and gather its output. The command is split on word boundaries, much like /bin/sh -c '...' does.
-mmstr If negated, no line of the output may match the specified mstr expression. Otherwise, at least one line must match. This option may be used multiple times as needed.
-rretval Exit status (a.k.a. return code or return value) of command must equal retval or the check will fail.
-tsecs Command will timeout if not completed within secs seconds (default is 5).
NOTE: If the command is passed using -e, the command string is split on word boundaries to create the argv[] array for the command. If passed on the end of the check line, DO NOT quote the command. Each parameter must be distinct. Only use quotes to group multiple words into a single argument. For example, passing command as "service bind restart" will work if used with -e but will fail if passed at the end of the check line (use without quotes instead)!
Example (Verify that the rpcbind service is alive): check_cmd_output -t 1 -r 0 -m '/is running/' /sbin/service rpcbind status
check_cmd_status
check_cmd_status [-t timeout] -r retval command [arg1 [...]]
check_cmd_status executes a command and redirects its output to /dev/null. The check fails if the exit status of command exit status does not match retval or if the command fails to complete within timeout seconds (default 5). Options to this check are as follows:
Check Option Purpose
-rretval Exit status (a.k.a. return code or return value) of command must equal retval or the check will fail.
-tsecs Command will timeout if not completed within secs seconds (default is 5).
Example (Make sure SELinux is disabled): check_cmd_status -t 1 -r 1 selinuxenabled
check_dmi_data_match
check_dmi_data_match [-h handle] [-t type] [-n | '!'] string
check_dmi_data_match uses parsed, structured data taken from the output of the dmidecode command to allow the administrator to make very specific assertions regarding the contents of the DMI (a.k.a. SMBIOS) data. Matches can be made against any output or against specific types (classifications of data) or even handles (identifiers of data blocks, typically sequential). Output is restructured such that sections which are indented underneath a section header have the text of the section header prepended to the output line along with a colon and intervening space. So, for example, the string "ISA is supported" which appears underneath the "Characteristics:" header, which in turn is underneath the "BIOS Information" header/type, would be parsed by check_dmi_data_match as "BIOS Information: Characteristics: ISA is supported"
See the dmidecode man page for more details.
WARNING: Although string is technically a match string, and supports negation in its own right, you probably don't want to use negated match strings here. Passing the -n or ! parameters to the check means, "check all relevant DMI data and pass the check only if no matching line is found." Using a negated match string here would mean, "The check passes as soon as ANY non-matching line is found" -- almost certainly not the desired behavior! A subtle but important distinction!
Example (check for BIOS version): check_dmi_data_match "BIOS Information: Version: 1.0.37"
check_dmi_raw_data_match
check_dmi_raw_data_match match_string [...]
check_dmi_raw_data_match is basically like a grep on the raw output of the dmidecode command. If you don't need to match specific strings in specific sections but just want to match a particular string anywhere in the raw output, you can use this check instead of check_dmi_data_match (above) to avoid the additional overhead of parsing the output into handles, types, and expanded strings.
Example (check for firmware version in raw output; could really match any version): check_dmi_raw_data_match "Version: 1.24.4175.33"
check_file_contents
check_file_contents file mstr [...]
check_file_contents looks at the specified file and allows one or more (possibly negated) mstr match strings (glob, regexp, etc.) to be applied to the contents of the file. The check fails unless ALL specified expressions successfully match the file content, but the order in which they appear in the file need not match the order specified on the check line. No post-processing is done on the file, but take care to quote any shell metacharacters in your match expressions properly. Also remember that matching against the contents of large files will slow down NHC and potentially cause a timeout. Reading of the file stops when all match expressions have been successfully found in the file.
The file is only read once per invocation of check_file_contents, so if you need to match several expressions in the same file, passing them all to the same check is advisable.
NOTE: This check handles negated match strings internally so that they "do the right thing:" ensure that no matching lines exist in the entire file.
Example (verify setting of $pbsserver in pbs_mom config): check_file_contents /var/spool/torque/mom_priv/config '/^\$pbsserver master$/'
check_file_stat
check_file_stat [-D num] [-G name] [-M mode] [-N secs] [-O secs] [-T num] [-U name] [-d num] [-g gid] [-m mode] [-n secs] [-o secs] [-t num] [-u uid] filename(s)
check_file_stat allows the user to assert


Lambs fall victim to severe spring weather
THOUSANDS of new-born lambs have been killed by severe winds and rain that have swept through parts of Britain, writes Nicholas Schoon.
Sheep farmers had been expecting fewer lambs this season because the proportion of pregnant ewes carrying twins and triplets rather than singletons was sharply down. This dearth of multiple births is put down to particularly cold, wet weather at tupping time last autumn when the rams were brought in to mate.
The ewes may have been in poor condition at the time of conception last year or soon afterwards. Now, in the spring, their lambs are being exposed to equally vicious weather conditions.
Each year 23 million lambs are born in Britain, starting in January in the southern lowlands and ending as late as May in more northerly uplands.
Farmers estimate that they lose up to 5 per cent of lambs at birth or soon afterwards, but this year the National Farmers' Union in south-west England is making an estimate of 8 per cent.
John Thomas, a Welsh NFU official, said: 'It has been a particularly bad season - the kind that happens only 1 year in every 10 with problem after problem. A wet, cold winter has produced poor spring grass. Recently we've had torrential rain, with the newborn lambs kept outside being soaked through. They're dying from pneumonia and related diseases.'
Peter Dowling, a Cumbrian farmer with 900 upland ewes, said: 'It's the wet and cold that does for them more than anything else. A dry back and a warm sun is what they need.'
Lambing has greatly altered in the past 20 years, with scanning of embryos in the womb now becoming routine and more and more ewes giving birth in warm, dry shelters - sometimes temporarily erected in the fields and hills. But, sooner or later, the lambs and their mothers have to be put outside to make room for other ewes about to give birth.

Hawach to Talk About the Applications and Differences Filter Membrane
Based on membrane filtration principle, Hawach provides different types of microporous membranes. Filter membranes are mainly used for the filtration of the mobile phase and samples in chromatographic analysis. PVDF membrane protein binding is widely used in gravimetric analysis, microanalysis, colloid separation, and sterility test. Filter membranes of different materials have different characteristics and different applications. The description and application of PES VS PVDF filter, PVDF VS nylon membrane, and NC membrane are as follows.
pes pvdf nylon nc membrane
1. PES filter membranes
Polyethersulfone (PES for short) is prepared by the condensation of 4,4′-bissulfonyl chloride diphenyl ether with diphenyl ether catalyzed by anhydrous ferric chloride. For the heat resistance ability, it is between polysulfone and polyarylsulfone. It has excellent aging resistance and can be used for up to 20 years at 180°C. It has good flame resistance and does not emit smoke even if it burns and also features good creep resistance.
Applications: For general alkali, aliphatic hydrocarbons, oils, and alcohols, the PES filter membrane's performance is stable, and suitable for physical and chemical sterilization, such as high-pressure steam, gamma radiation, and ethylene oxide sterilization, with high bubble point and excellent membrane integrity. The PES filter membrane material has a very low protein adsorption rate, which can ensure the stability of the components of the filtered drug solution, and is suitable for disposable precision filtration infusion sets and anesthesia drug solution filters. PES is often used in the manufacture of hemodialyzers, blood concentrators, artificial lungs, etc. due to its excellent mechanical properties, stable wetting strength, and blood compatibility.
PES filter vs PVDF. PES vs PVDF filter. PVDF filter membranes have higher oxidant resistance and mechanical strength than PES filter.

2. PVDF filter membrane (Polyvinylidene fluoride membrane)
PVDF membrane, or polyvinylidene fluoride membrane, is a kind of solid-phase support commonly used in Western blotting. The PVDF membrane is hydrophobic, and the pore size of the membrane can be large or small. As the pore size of the membrane continues to decrease, the membrane is more firmly bound to low molecular weight proteins.
For proteins larger than 20000, a 0.45um membrane is used, and for proteins smaller than 20000, a 0.2um membrane is used. The use of the PVDF membrane requires pretreatment. The purpose of methanol treatment is to activate the positively charged groups on the membrane, making it easier to bind to negatively charged proteins. With high mechanical strength, the PVDF membrane is an ideal solid support material in the imprinting method. In addition, PVDF vs PES. PVDF filter membranes have a slower flow rate than PES filter membranes;
Applications: Hydrophobic polyvinylidene fluoride membrane is mainly used in gas and vapor filtration, and high-temperature liquid filtration; hydrophilic polyvinylidene fluoride membrane is mainly used in tissue culture medium, additives, and other sterilization filtration solvents, and purification filtration of chemical raw materials, aseptic processing of reagents, filtration of high-temperature liquids, etc.

3. Nylon membrane
Nylon membrane is a synthetic long-chain polyamide membrane, which has a strong binding ability to nucleic acid and protein and can replace nitrocellulose membrane for molecular imprinting and hybridization experiments. Nylon membrane features good temperature resistance, which can withstand 121℃ saturated steam hot-press sterilization for 30min, and the maximum working temperature is 60℃; also, it has good chemical stability, which can withstand dilute acid, dilute alkali, various organic and inorganic compounds such as alcohols, esters, oils, hydrocarbons, halogenated hydrocarbons, and organic oxides.
Applications: Electronic, microelectronics, semiconductor industry water filtration, tissue culture medium filtration; liquid medicine filtration, beverage filtration, high-purity chemical filtration; filtration of aqueous solutions, and organic mobile phases. It has the widest applications, such as aqueous solution and organic mobile phase filtration; filtration of beverage and chemical liquid; filtration of tissue culture medium, and so on.

4. NC membrane
Nitrocellulose filter membrane (NC membrane for short) is used in Northern Blot, Southern Blot, and Western Blot. Hybridization techniques include solid-phase hybridization and liquid-phase hybridization. Solid-phase hybridization technology is currently more commonly used.
The nucleic acid to be tested is bound to certain solid-phase support and then hybridized with the labeled probe in the liquid phase. Nitrocellulose membranes are commonly used for solid supports.
Difference between nylon and PVDF filters membrane, and NC filter membrane
Nylon vs PVDF filter, NC filter membrane. Difference between nylon and PVDF filters membrane, Nylon membrane is an ideal nucleic acid solid support and there are many types; nitrocellulose membrane is currently the most widely used solid support with the cheapest price; the PVDF membrane is somewhere in between.
1. In terms of the toughness of nylon membrane, PVDF membrane, and NC membrane
The nylon membrane is stronger; the PVDF membrane is stronger; the nitrocellulose membrane is more brittle and easily broken.
2. In terms of the binding capacity of nylon membrane, PVDF membrane, and NC membrane
Nylon vs PVDF filter. Nylon membranes can bind DNA and RNA up to 480-600μg / cm2, and can bind nucleic acid fragments as short as 10bp; the PVDF membrane can bind DNA and RNA up to 125-300μg / cm2; nitrocellulose membranes can bind DNA and RNA up to 80-100μg / cm2. The 200bp nucleic acid fragment has a weak binding ability.
3. In terms of temperature adaptability of nylon membrane, PVDF membrane, and NC membrane
After the nylon membrane is baked or irradiated with ultraviolet rays, some of the pyrimidine bases in the nucleic acid can be combined with the positive charge on the membrane; the PVDF membrane is firmly bonded and resistant to high temperatures, and is particularly suitable for Western blotting; the nitrocellulose membrane relies on hydrophobic interaction to bind DNA and the binding is not strong.
0.45 Disc Vacuum Microfiltration Membrane hydrophilic ptfe membrane filter hydrophobic membrane and hydrophilic membrane
4. In terms of repeatability of nylon membrane, PVDF membrane, and NC membrane
(1)The nylon membrane can be used repeatedly for molecular hybridization. After hybridization, the probe molecules can be eluted by alkali denaturation; the PVDF membrane can be reused; the nitrocellulose membrane cannot be reused.
(2) Compared with nitrocellulose membranes, PVDF membranes have superior performance in protein retention, mechanical strength, and chemical compatibility. The typical binding capacity of commercially available nitrocellulose membrane is 80-100μg / cm2, while the binding capacity of the PVDF membrane is 100-200μg / cm2 (and the binding strength of PVDF is 6 times stronger than nitrocellulose membrane!).
But the biggest advantage of PVDF membranes is not only this: better mechanical strength and chemical resistance make PVDF membranes ideal for various staining applications and multiple immunoassays, and a single lane copy of the gel can be used for multiple purposes, in particular, it is necessary to do N-terminal protein sequencing.
Under fairly "severe" cleaning conditions, the PVDF membrane remains intact when the nylon or nitrocellulose membrane has been degraded, so PVDF is also the best choice for protein sequencing. But it is not suitable for fluorescence. Particular attention should be paid to PVDF membranes that require 100% methanol pretreatment (not more than 15 seconds) and then equilibrated with buffer before they can be used.
(3) Since the protein-bound on the NC membrane will be replaced by some detergents, use a milder Tween20 when blocking, and the concentration should not exceed 0.3%. Generally speaking, the purer the NC membrane, the higher its protein binding capacity, so it is a consideration to increase the sensitivity and resolution of WB and improve the purity of the membrane used. If the NC membrane is mixed with some cellulose acetate, which has been mentioned before, it will affect the protein binding.
(4) The use of the NC membrane is also very simple. For example, no formaldehyde pretreatment is required, as long as it is infiltrated on the surface of non-ionized water to expel the air bubbles in the membrane, and then equilibrated in electrophoresis buffer for a few minutes; the NC membrane

Jet Fuel Mixture Activity
In this activity you will learn how to use a JAVA 3D Slicer to analyze 3D scientific data sets. This HDF three dimensional data set represents the concentration of a fuel/air mixture in a closed container for an instant in time (750 units of time) after the fuel was injected into the container. The data is from an experiment that simulated the injection of fuel into the combustion chamber of a jet engine. Each fuel concentration value is represented by the combination of the x, y, and z coordinates which define the dimensions of the box. The purpose of the experiment was to test different shapes of fuel injection ports to derive the best shape for achieving the optimal fuel/air mix. In the concentration diagram below you can see the elliptical injection port on the left; this is where the fuel is injected into the chamber. Next, the fuel flows to the right and forms an elliptical cloud of fuel and air.
In this activity you will use the JAVA 3D Slicer to view the three dimensional data set. While "slicing" through the x, y, and z planes you will observe trends in the fuel concentrations. As you move the slice through the data the observed colors will change; red stands for the highest concentration and purple for the lowest concentration.
To perform this activity you will use the first data set in the brown.hdf file (although it should already be selected, you can make sure by selecting the drop down menu from the upper right hand corner of the JAVA applet). The data set exists in the JAVA 3D Slicer's folder; it is named brown.hdf. To access the file you select the drop down menu on the top of the JAVA applet and select "Open URL", then type "brown.hdf" (without the quotes). The data set will then load on the screen and you can move the "slice" through the data to observe certain trends and concentration levels.

Tips to Become a Receptionist in Uganda: Basic Skills Salary and Requirement
Tips to Become a Receptionist in Uganda: Basic Skills Salary and Requirement.
By: alljobspo.com
KAMPALA, Uganda - March 7, 2019 - PRLog -- Education: High school diploma or equivalent; certificates and training available and preferred
Experience: 1-3 years of experience; many employers provide training
Salary: UGX 13,200,001
Receptionists work as administrative sales person in a number of office settings, from architectural organizations to doctors' offices to large companies. Specific duties depend mainly after the workplace, but receptionists generally answer and route incoming calls and provide general help clients or customers. Additionally they assist employers with incoming and outgoing mail, faxes, email messages and other communications. This kind of work can be demanding, and receptionists sometimes must deal with difficult callers or customers. Therefore, strong oral and written communication, customer service and tuning in skills are necessary. Also, receptionists need organizational skills and familiarity with office technology, such as Microsoft company Office, billing, bookkeeping and database software.
The income for receptionists vary significantly with regards to the industry and corporation in which they work. However, the average gross annual salary for receptionists in all industries in Uganda was about UGX 13,200,001. Today let's discuss on the educational requirement, receptionist jobs and need to improve as a receptionist.
Educational Requirement
The minimum education needed to become a receptionist is a high institution diploma. However, many organisations want to hire receptionists with administrative skills in addition to experience. One way to obtain administrative skills is by earning a certificate in clerical studies or office assistance, which is often earned in about a year and usually covers data entry, word processing, payroll accounting, business math, customer care, office management and office software.
These programs can be found in many community, specialized and vocational colleges. Hold in mind that associate's degree programs related to communications or business can provide you an advantage over the competition, though a 2-year degree is generally not expected for receptionists.
Those who choose to not attend school may want to pursue training independently. For instance, you could complete online training for office software, such as tutorials and webinars on Microsoft Office and other office technology. You might also volunteer within an office setting to develop office and communication skills. Such volunteers may gain experience operating basic office equipment, such as multi-line phone systems, and interacting with people.
Receptionist Job Employment in Uganda
After attaining the skills required for the task, it's time to commence the task of jobs search. A large number of different industries employ receptionists. As the U. H. Bureau of Labor Figures points out, many receptionist jobs are in health care, legal firm etc. However, the set of potential employers is long and includes religious organizations, design firms, publishing companies, insurance firms, market research firms, medical organizations, charities, real real estate companies and educational services.
It's wise to immediate your job search relating to your skills. Distinct employers need people with specialized skills. For example, those who are bilingual have an advantage when trying to get careers in organizations where familiarity with another language is needed. When seeking employment, consider your long-term career goals. Working as a receptionist provides regarding the daily ins and outs of other positions within your industry.
In Uganda for you to easily get all the latest receptionist jobs (_URL_ is to use jobs search engine like Alljobspo.
They update all the current receptionist,secretariat, cleaning jobs etc.
Improve As a Receptionist
Receptionists who show great effectiveness in clerical skills may have the possibility to progress to a higher position such as an management assistant, personal assistant or secretary. When considering job advancement, receptionists should give attention to honing administrative skills and networking to make contacts within their industry.
A large number of receptionists earn certificates in clerical studies or office assistance to obtain the administrative skills necessary for this career. And with time, they may move forward to positions such as administrative assistant, personal associate or secretary.

Designing Infrastructure: What are the Best Practices?
Posted by Eric Wright on Dec 4, 2019 11:48:00 AM
Eric Wright
Find me on:
We are continuously being confronted with challenge in designing infrastructure. Every aspect of our infrastructure has potential pitfalls for performance, resiliency, and the challenges faced with dynamic workloads.
Different software and hardware vendors often produce reference architecture documents and the classically titled "Best Practices" recommendations to go along with their offering. While they are meaningful to a degree, we also have to be acutely aware of the dangers of the supposed best practices. The reason for that is the subjectiveness of the designs. Let's explore a little why this is the case.
Today's Best Practices are Tomorrow's "What we're we thinking?"
We may laugh now at the classic misquote from Bill Gates that "640kb ought to be enough", but this has a very important context that is wrapped around it. As noted above, the original quote which may have triggered it, was around the effective upper reach of memory for PC hardware. Much has changed since then of course, so this is the most important thing to be wary of when attaching a Best Practice to a design. Without understanding the constraints that derived the upper boundary, we will inevitably fail to adjust when the constraints are lifted and the boundaries change.
The sports analogy to this is "moving the goal post" which is another popular phrase. It's the concept that every time you get closer to the goal, the variables change and the boundary is shifted which invalidates the original goal.
It isn't that the goal was incorrect, but the rest of the variables have now lessened the value of the goal. In hardware terms, imagine still using 640kb of RAM to run a modern Windows desktop. You can probably guess how that will perform.
Resiliency is a Malleability
On the concept of resiliency, we design for potential failures throughout the system. We can do this by providing multiple paths to a systems via the network, or by mirroring data to another location, or creating clustered services to back our applications.
Each of these resiliency strategies is based on protecting at different points of failure throughout the overall system. This is also a challenge.
Imagine a scenario in earlier days of distributed computing where a production system would have a twin server located next to it as a hardware hot spare in case of failure. That may seem bizarre in today's data center, but at the time it was the best strategy to reduce the time to replace failed hardware.
I say that resiliency is malleability because it is done based on a number of variables depending on the design. These variables will change, and thus the Best Practices would have to change along with them.
Printed Docunentation: the Path to Legacy
Printing isn't the issue. Retaining documents in printed format is. When we print a server build document, or an application deployment document, we freeze the state of that build process in time. Two weeks later someone may discover that line item 28 to plug the network cables into two switches in the same rack is a terrible idea because the network team is now using the same uplink paths to the core and we have a single point of failure.
The electronic documentation is updated, but the printed doc is no longer what it claims to be with its 45 pitch font boldly stating "Best Practices" on the cover page. If you don't believe that this occurs, I would encourage you to ask your sysadmin for the build documentation and you may find that they peek through a pile of paper for one.
The moment a document is printed, it's static. Designs, constraints, and workloads are dynamic. You can easily see where this creates a problem.
Software Upgrades and Best Practices
Do you revisit all of your best practices for applications and infrastructure as each software update occurs? I'm going to go out on a limb and say that as many people update environments with best practice designs as those who read the entire End User License Agreement before clicking "I Agree".
Even teams that make use of configuration management solutions and other orchestration tools can find themselves at a point of being caught off guard by changes to the feature set in a new piece of software or one that received an incremental update.
Schrodinger's Best Practices
At any moment in time, the state of your infrastructure is both known and unknown. Much like the classic conundrum presented by the concept of Schrodinger's Cat, the Best Practice is both failing and winning.
As you may already know, the core of what we do at Turbonomic is built around the concept of a Desired State, which is dynamic and continuously changing based on the shift of supply and demand of resources. The key part of the message is that a Best Practice is like the Best Athlete. If we keep using the same one, the rest of the environment will change around us and leave us behind.
No matter how good we were at the point in time, the environment is constantly changing and along with it, so are the Best Practices. This is why we have to change the way we think in the modern data center.
Best Practice guidelines are like world records: meant to be broken by something better.

Sensitivity Analysis with Building Simulations to Support the Commissioning Process
MetadataShow full item record
Building performance simulations can support the commissioning process of buildings. This paper introduces an approach to implement saving measures using sensitivity analysis with a simulation model and data analysis of measured data from the building. The building that is analyzed is a large non-residential building that was equipped with a data acquisition system. Global sensitivity analysis methods including Monte Carlo (MC) techniques are used to determine the parameters and variables for which the buildings energy consumption is most sensitive to. This information is employed for the optimization of the building operation. Furthermore, the MC simulations are used to quantify the uncertainty of the simulation results given the uncertain simulation parameters or variables. The MC simulations of the building are used to calculate the energy savings for some operational improvements and the corresponding uncertainty. One saving measure was implemented in the real building and the result of the implementation is analyzed using the measured data.

Authors: CATALINA CIOBOTARU, GEAVIT MUSA
Abstract: The monochromatization effect (M-effect), which consists in the reduction of an electronegative-electropositive gas mixtures discharge emission spectrum to only a few or a single line, was largely explained in our previous published papers together with their generation mechanisms, namely the polar ion-ion recombination and the energy resonance condition. This paper presents a kinetic model for the M-effect based on the radiative and collisional processes which appear between 1s_2, 1s_3, 1s_4 and 1s_5 Paschen levels, in Penning gas mixtures, where this effect was observed to be the most powerful.

In observance of Passover and Easter, millions of Jews and Christians are retelling ancient stories of faith from the Holy Land. But when it comes to day-to-day life in that ancient world — what people ate, how they flirted, how they stayed clean — how much do we really know? Religion scholar Scott Korb takes on that question, and the real nitty-gritty of that existence, in his latest book, Life In Year One: What the World Was Like in First-Century Palestine.
A historical travelogue of sorts, Life In Year One details the tumultuous era in which Jesus lived. Korb, a professor at New York University and The New School, draws from ancient texts, archaeology, and ancient and modern historians' often contradictory accounts, to paint a picture of that ancient world — when the Jewish people chafed under Roman rule, when bandits and assassins roamed the countryside, and when entire economies and belief systems were being transformed.
A Catholic himself, Korb makes clear in his very first chapter: this is a book about who Jesus' neighbors and contemporaries might have been, not a book about Jesus. "Today we still can't seem to agree about who he was," Korb writes. "It's worthy of a lively debate, to be sure — just not here."

The use of additives in plastic caps and closures is a practical requirement to allow for easier processing and handling. Performance restrictions and requirements in consumer sensitive applications, such as food and drinks, increases the demand for more advanced additives that will offer an improved quality to reduce impact on the final product.
Slip, torque and mold release additives allow plastic screw caps and closures to be produced and used more efficiently. Our torque release additives not only offer processors and end-users flexibility, performance and better quality plastics as expected, they also provide exceptional stability with reduced odour and colour degradation.
Standard torque release additives can demonstrate poor oxidative stability that can result in poor odour, taste and taint. This can have a huge impact on the finished article, for example bottled water.
Our range of highly stable additives have been shown to significantly reduce odour and taste issues in more challenging environments, such as in warmer climates or when exposure to UV light.
In particular, Incroslip SL, is extremely stable and therefore less prone to oxidation. This can add value in caps and closure applications such as water bottle caps where taste and odour is critical.
Optimising torque release performance of Incroslip SL in HDPE caps
You can achieve the excellent torque release performance of traditional erucamide-based slip additives, with the increased stability and superior organoleptic properties of Incroslip SL. These properties help to avoid the taste, odour and colour issues that may be faced with traditional erucamide-based additives.

A manufacturer of bottled water approached Croda to reduce poor organoleptic properties that were present due to using a standard fatty acid amide torque release agent for the bottle cap.
The manufacturer was using an ozone sterilisation process so Croda suggested using Incroslip Q, a tailored solution that can minimise taint and taste issues while providing the level of torque release force required to remove caps.
Incroslip Q helped the manufacturer to balance good organoleptic properties through the ozone sterilisation process and good cap closure properties to ensure a well-received consumer product.
The Incroslip range can also aid in the molding and release of caps in injection and compression molding process. This allows for continuous production and the elimination of silicone sprays while also improving surface finished and decreasing the number of rejects and waste.
Torque release additives allow caps and closures to be tightly added to bottles while still allowing easy removal in end use.

1st Kearny Highlanders
|FIRST KEARNY HIGHLANDERS: TRADITION'S WEIGHT|
|Unit Profile (as of 3067)|
|CO||Colonel Edward Senn|
 Early History
The First Kearny Highlanders are the oldest of the Northwind Highlanders formations, formed with volunteers from volunteers mining settlement Kearny on Northwind. The unit fought early battles for various Great Houses, including of the Capellan Confederation. Its career in these early times were checkered with victories and defeats.
The unit first notable conflict was during the 1st Andurien War, where the unit was fighting for the Confederation. The unit was nearly routed on Lopez by elements of House Marik's Oriente Hussars. This route nearly cost the unit its career.
- 2761 - 1st Kearny redeem themselves by successful occupation of the Davion world of Demeter with odds against them.
 Succession Wars
- 2801 - The unit is deployed to Lincoln to successfully defend the world from elements of House Kurita's Dieron Regulars attempt raid the world.
- 2865 - 1st Kearny returned to Northwind to defend the world from House Marik regulars and their mercenary support units. The 1st Kearny was able drive off the invaders. They inflicted heavy damage on the flee units, including mercenary unit known as the Jal's Jaegers but lost half of its men & equipment in effort. The unit resolved to rebuild itself with heavier equipment, so it restricted self to raiding until it fully rebuilt.
- 2866 to 2880 - 1st Kearny conducts number of raids Free Worlds League holdings for 'Mechs and supplies. Recovering large quanity of medium class BattleMechs to allow the regiment to fully recover.
- 2943 - The 2nd Company of the 2nd Battalion, under the command of Captain Erika Laurel leader her company heald the defense of world Hsien against Marik troops until the Warrior House Ijori regiment arrived.
- 3028 - Stationed on Highspire the 1st Kearny departed, after news reached them of the negotiation between the clan elders and the Federated Suns, to their new home on Northwind.
- 3025 - Commanding Officer of the 1st Kearny was Colonel Timothy Senn
- 3050 - Commanding Officer of the 1st Kearny was Colonel Edward Senn
- 3059 - Commanding Officer of the 1st Kearny was Colonel Edward Senn
- 3067 - Commanding Officer of the 1st Kearny was Colonel Edward Senn

Campus: San Diego State University -- February 9, 2005
SDSU, Mexican University Complete Comprehensive Tijuana
River Watershed Atlas
Researchers at San Diego State University, along with partners around San Diego
and at El Colegio de la Frontera Norte (COLEF) in Mexico, have completed the most
comprehensive set of geographical data ever assembled about the Tijuana River
watershed, a crucial step toward successful long-term planning and management
for the fast-growing binational area.
The Tijuana River Watershed Atlas, in development for nearly a decade, includes
approximately 80 photographs, maps, and text in English and Spanish. It captures
much of the diversity and complexity of the watershed, a 1,750-square-mile drainage
basin that stretches from the Pacific Ocean at the Tijuana River Estuary north to
Mount Laguna and southeast into remote mountains and valleys located well inside
Richard Wright, professor of geography at SDSU and Rafael Vela of COLEF, general
editors of the project, said the new atlas is an important breakthrough because
it presents the first unified view of the watershed as seen by scholars on both
sides of the border.
"For the first time, policymakers and planners from the United States and Mexico
can work from a common set of data," Wright said. "That has been one of the
impediments to binational cooperation over the watershed in the past. If you're
not working with the same information, how can you productively discuss your
similarities and differences of opinion?"
The atlas, a boxed set of dozens of maps, photos and text each suitable for display
on a wall, includes many types of data, ranging from topography and climate
information to human population and land use patterns.
In addition to serving as a policy and planning tool, Wright said the atlas also
serves as an effective educational aid for demonstrating how the two nations are
intertwined by the watershed's systems and landscape. More than 200 copies of the
atlas are being provided to the San Diego Natural History Museum for use in the
PROBEA project, a binational environmental teacher education program. Some
copies of the atlas will be available to other educational agencies at no cost.
Compiling the atlas was a challenging endeavor at times, Wright said. The
researchers had to arrange for National Oceanographic and Atmospheric Administration
(NOAA) aircraft to fly over Mexican airspace to take aerial photographs of the
areas of the watershed south of the border. SDSU partnered with the San Diego
Association of Governments to obtain needed satellite imagery. Common classification
systems had to be created in English and Spanish for some data, such as land use.
In some cases, maps required extensive field work and many months of labor to
For more information or to obtain copies of the atlas, call _PHONE_ or

research and production of the Tijuana River Watershed Atlas was provided by the
Southwest Consortium for Environmental Research and Policy, the U.S. Environmental
Protection Agency, NOAA, and SDSU's Institute for Regional Studies of the
Californias (IRSC) and Department of Geography Center for Earth Systems Analysis
Research. Harry Johnson of the Department of Geography was the chief cartographer
for the atlas and Paul Ganster, director of IRSC, was the principal text editor.

A novel precision-engineered microfiltration device for capture and characterisation of bladder cancer cells in urine
Review articleOpen access
Abstract:
AbstractBackgroundSensitivity of standard urine cytology for detecting urothelial carcinoma of the bladder (UCB) is low, attributable largely to its inability to process entire samples, paucicellularity and presence of background cells.ObjectiveEvaluate performance and practical applicability of a novel portable microfiltration device for capture, enumeration and characterisation of exfoliated tumour cells in urine, and compare it with standard urine cytology for UCB detection.MethodsA total of 54 urine and bladder wash samples from patients undergoing surveillance for UCB were prospectively evaluated by standard and microfilter-based urine cytology. Head-to-head comparison of quality and performance metrics, and cost effectiveness was conducted for both methodologies.ResultsFive samples were paucicellular by standard cytology; no samples processed by microfilter cytology were paucicellular. Standard cytology had 33.3% more samples with background cells that limited evaluation (p < 0.001). Microfilter cytology was more concordant (κ = 50.4%) than standard cytology (κ = 33.5%) with true UCB diagnosis. Sensitivity, specificity and accuracy were higher for microfilter cytology compared to standard cytology (53.3%/100%/79.2% versus 40%/95.8%/69.9%, respectively). Microfilter-captured cells were amenable to downstream on-chip molecular analyses. A 40 ml sample was processed in under 4 min by microfilter cytology compared to 5.5 min by standard cytology. Median microfilter cytology processing and set-up costs were approximately 63% cheaper and 80 times lower than standard cytology, respectively.ConclusionsThe microfiltration device represents a novel non-invasive UCB detection system that is economical, rapid, versatile and has potentially better quality and performance metrics than routine urine cytology, the current standard-of-care.

FAQ
QuestionAnswer
What equipment and software do I need to track migrating cells?You will need a phase contrast microscope or fluorescence inverted microscope, heating stage, time-lapse video equipment (CCD camera, video camera, acquisition software), motorized stage and autofocus (x, y, z) and the NIH Image J plug-in software. Instructions for free download of this software are available at _URL_
Can I conduct the migration assaywith fluorescently stained cells?Yes. Fluorescent staining is compatible with the migration kit. The cells are pre-stained before loading into the slide.
Can I use a normal digital camera connected to a microscope to take images manually at different time points (e.g. if the microscope doesn't have video equipment)? If so, can this data be opened in the Image J plug-in software and analyzed?Yes. To analyze the pictures with the Image J software, just follow these steps: 1. If taking pictures manually at different time points, be sure to take them with the slide always at the same position on the microscope. 2. Save the image files in order. 3. Import the files into Image J—the software will organize the images in order. 4. Analyze the data using Image J software.
Can I take images of assays running concurrently in different chambers on the same slide?This is easily done with a microscope that has a computer-controlled movable stage. If the microscope doesn't have a computer-controlled movable stage, it is very difficult to manually take all the pictures/videos from 3 chambers at different time points (or at the same time) since the registration (original point) is lost for each of the different chambers. The migration of cells is very small, usually several microns/hour. If the photos are taken manually in a slightly different area, the trace of the cells is not accurate. In this case, we recommend running one chamber at a time in individual assays.
If multiple assays are run on a slide and images are captured for all of them, can the Image J software identify which chamber each photo derives from at different time points?No, Image J software cannot sort the photos taken of simultaneous assays. You will need to sort the pictures before loading into Image J.
How can I correctly track the recommended 20 to 50 cells which are necessary to obtain representative data in one image/frame?Please refer to the Image J plug-in software document available at _URL_
What the effective surface area of the viewing area?The effective viewing area depends on the objective magnitude of the microscope used. The appropriate magnitude should cover the entire area encompassing the cells, the source, and the paths of the cells migrating towards/against the source (1 mm, y-direction).
I am using fibronectin and I never let it dry out before seeding cells. However, the protocol suggests drying the slide out completely. Can I seed the cells immediately after coating like I normally do when culturing my cells?No. As this is a microfluidic device, it is critical to ensure complete evaporation of fluid from the slide prior to cell loading so that air bubbles do not get trapped in the channels.
Do I need to worry about CO2 or O2 gas exchange?For CO2 dependent cell lines, CO2 gas exchange is necessary during real-time imaging. The slide's plastic is gas-permeable thus allowing for some gas exchange to occur. A CO2 gas exchanger is optimal.
Can the conditioning or incubation of the chambers be shortened at all?No. As this is a microfluidic device, it is critical to ensure complete evaporation of all fluid from the slide prior to cell loading so that air bubbles do not get trapped in the channels.

How to wrap jiaozi (1:50)
The Spirit and Symbol of Chinese New Year Foods
By James B. Young
Many cultures eat symbolic foods for the new year. Some foods are chosen because they are reminders of money, abundance, or religious symbols. But the Chinese culture adds another dimension: the way the food's name sounds in the spoken language.
Niangaocantonese_0155Cantonese-style Niangao
Spoken Chinese is filled with what appear to be an exceptional number of homonyms -- words that sound alike but have different written meanings. This explains apparent mysteries, such as: Why do images of bats appear in Chinese works of art? And why is the character for luck hung upside down in Chinese homes?
The answers lie in the sound of the language. In some Chinese dialects the spoken word for "bat" sounds like the spoken word for "luck." So bats are considered good luck. Similarly, the spoken word for "upside down" can sound like the spoken word for "arrive," so "luck" turned upside down means luck has arrived. This kind of symbolism appears throughout Chinese culture and especially for the Lunar New Year feast. (Note: Chinese dialects are tonal languages and sometimes the tone is ignored in the interest of making the association.)
For the feast, some Chinese families serve eight or nine dishes because these are "lucky numbers." The word for "eight" can sound like the word for "prosperity." The word for "nine" can sound like the word for "long-lasting."
Foods on the Chinese New Year table
Food aficionados are no doubt familiar with the Chinese dumplings known as "jiaozi."
Jiaozi_0207-2Wrapped jiaozi ready for cooking
For the uninitiated, jiaozi are made from a circle of flour wrapped around a morsel of meat and vegetables and either steamed, boiled or fried. Jiaozi are an integral part of new years celebrations for many Chinese families -- especially the North. Their shape resembles that of ancient gold and silver ingots known as "yuan bao," and this may be reason enough to include them in new years celebration. But "jiao zi" was also the name of the first Chinese paper money. And "jiao" can sound like "to hand over" – as in handing one year over to the next.
The Chinese word for "fish" can sound like the word for "abundance" or "surplus." So the phrase "abundance every year" sounds like the phrase "fish every year." To drive the symbolic point home some families cook a whole fish on new-years eve, eat half, and finish the rest on new years day.
Niangao_0172Shanghai-style Niangao
In Eastern China another popular new years delicacy is "niangao" or glutinous rice cake. Niangao literally means "year cake," but it can also sound like "year elevated" – implying that the new year will be better than the old.
People living near Chinese communities are probably familiar with the Cantonese saying "Kung Hei Fat Choy" (Gong Xi Fa Cai, in Mandarin). It means, "congratulations and be prosperous." But fat choy (fa cai) also sounds like the name for black hair moss, which makes black hair moss a treasured ingredient in Chinese new years dishes. A word of caution, though, in 2007 biochemists in Hong Kong discovered that black hair moss contains the toxic amino acid BNAA, which is linked to degenerative nerve diseases such as Alzheimer's, Parkinson's, and dementia. They have called for a total ban on the sale of black hair moss in China. For those seeking an alternative, one scientist suggests using lettuce. Its name, sounds like "creating prosperity" in both Cantonese and Mandarin.
Moss_0220-1Chinese scientists suggest substituting lettuce for black hair moss (fat choy / fa cai)
The list of auspicious sounding (or shaped, or colored) Chinese foods goes on and on. They are all candidates for a Chinese New Years feast. Different parts of China pronounce words differently and have different customs, which leads to favoring different foods. But the result is the same: Whether it is shape, color, or sound, the foods selected represent the wish for a happy, healthy, and prosperous new year.

Parents across the globe usually take their role as providers very seriously. But in an unusual role reversal, paper wasp queens beg their young for a meal.
When they get peckish, the queens wag their abdomens across their nests, creating vibrations that "ask" for a nutritious saliva snack.
"She does it when she's hungry, not when the larvae are hungry. So the adult is begging for food back from the larvae," said Bernard Brennan, the postdoctoral researcher at Yale University in New Haven, Connecticut, who made the discovery.
Paper wasps (Polistes dominulus) are among the best studied insects in the world. But the reason for the queens' wagging behavior remained a mystery until Brennan started researching it as a graduate student at Cornell University in Ithaca, New York.
The evolutionary biologist presented his most recent findings last week at the annual meeting of the Animal Behavior Society in Snowbird, Utah.
Brennan's research shows how the wasps manage their food supply between the queen and her young. It also unmasks the surprisingly active role the young wasps play in the relationship: They control how much saliva they give up.
"This is certainly a fascinating example of parent-offspring communication, in a context where adults are not only feeding the young, but also being fed by them," Rex Cocroft wrote in an e-mail to National Geographic News. Cocroft is a biologist who studies animal communication systems at the University of Missouri in Columbia.
Like all adult wasps, bees, and ants, adult paper wasps are limited to liquid diets, because a section of their bodies between the head and the abdomen is extremely narrow. Solid chunks of food just wouldn't fit through.
"All digestion occurs in the abdomen, so their food has to get through this constriction," Brennan, the Yale biologist, said.
But wasp larvae, which are shaped more like fat worms, are able to eat a wider range of food.
Adult paper waspsusually queensexploit this difference by capturing caterpillars and feeding them to larvae in the nest. The larvae digest the caterpillars and produce nutrient-loaded saliva that is fed back to the adults.

Jackson deserializes to type you tell it to, so if you declare property to be of type long or Long it would construct it as long. But maybe you are binding to "untyped" structure like Map? If all values are of type Long, you could just declare type appropriately, like:
Map map = objectMapper.readValue(json, new TypeReference>() { });
Alternatively might be able to add custom Deserializer for Object.class with different handling (default deserializer is org.codehaus.jackson.map.deser.UntypedObjectDeserializer).
It might help if I knew what you are actually trying to do -- Integer and Long are both numbers, so often distinction does not matter a lot... so what is the reason to require Longs?

The deserialized numbers are IDs of objects that I would like to retrieved through the Hibernate. When I use Integer it throw an exception that it can convert from integer to long. – eugenn Jun 30 '10 at 13:14
Then the easiest way might be to explicitly just convert these, something like 'Long id = numberValue.longValue();'. Unless if map only has numeric values, in which you can declare types as Map (as I mentioned above) – StaxMan Jul 1 '10 at 7:06
_USER_ explicit conversion will become redundant when the IDs become long so wouldn't some form of type casting (e.g. JsonTypeInfo) be preferable? – ajostergaard Aug 24 '13 at 7:02
Jackson does type co(nv)ercions where necessary. So if POJO indicated that long or Long are needed, that's what you'd get. The original post is vague enough that I don't really know enough to know what the right answer is. But polymorphic type inclusion does not seem to be part of the picture. – StaxMan Aug 27 '13 at 17:43

Don't Blow A Gasket!
Don't blow a gasket! Who hasn't heard this old adage at some time? What does it actually mean, and for that matter, what is a gasket? Gaskets are simple structures used to fill in and seal the spaces where two surfaces meet, usually to prevent the leakage of a material under pressure. A good example is the interfacing of two machined flat surfaces, as occurs with various gasoline or diesel engine parts. The proper and continued functioning of an automobile engine, and most other machinery, requires that no fluids leak in or out in an uncontrolled manner. To prevent such leaks, the various machined surfaces must have all gaps and spaces between them perfectly filled and sealed. Machined surfaces, although quite smooth, contain numerous small imperfections and may not be true from one end to the other.
When two such surfaces are brought together, it is generally true that they cannot form a tight seal against each other without being placed under undue or excessive stress when the bolts are tightened to join the two pieces. It is entirely possible to machine surfaces of parts so that a nearly perfect surface match between them is achieved, but this is a very expensive proposition, and does not work well in the context of any fast-paced high-production industry. To reduce machine operations and the associated costs, gaskets are commonly used to mate flat surfaces.
A gasket is a thin layer of material that readily conforms to the surface of the material around it, and ideally does not interact with the fluids that it must contain. The shape of the gasket matches the shape of the two surfaces that it joins. The gasket material deforms under the applied pressure to fill in the tiny imperfections and compensate for any lack of trueness in the machined surfaces. This ensures that fluids passing from one part to another do not leak out into the environment. Generally the more pressure that can be safely applied to a gasket, the better it serves.'To blow a gasket' means that it has failed during operation and allowed pressurized fluids to blow out of the machine. A fluid leak can result, with fluid 'blowing out' under pressure, and the effects can range from a relatively innocuous but noisy exhaust gas leak to a severely damaging internal coolant or oil leak.

Tank Math: Full or Empty?
In the "Know-How" section of the March issue, Steven J. Henkind wrote about how fuel gauges operate and how you can prevent fuel-gauge errors. Here's the mathematical formula he discussed in the story.
You can also calculate the amount of fuel in a tank mathematically. For a rectangular tank, the calculation is easy: the overall volume of the tank = Length x Width x Height; if the measured height of the fuel is M% of the height of the tank, then the fuel contained = M% x Overall Volume.
The calculation is more complicated for more complex shapes. The tank shown here is an isosceles-triangular right prism, where L is the length, W is the width, H is the height, and the two (equal) sides are both S. If h is the height of the fuel, the ratio h/H is what a fuel gauge that measures height, not volume, will display. To determine the actual volume for this example, use the following formula:
Volume = (h/H)2 x ((L x W x H)/2).
For example, if L = 4 feet, W = 3 feet, and H = 3 feet, the formula holds that when the tank is full (h=H), Volume = (1)2 x (4x3x3)/2 = 18 cubic feet. But, when the fuel gauge reads 1/2, the actual volume in the tank is (1/2)2 x (4x3x3)/2 = (1/4) x 18 = 4.5 cubic feet. In other words, although the fuel gauge reads 1/2 full (because of the (h/H) ratio), the tank in the illustration is actually only full. To convert from cubic feet to gallons, use the conversion factor 1 cubic foot = 7.48 U.S. gallons. Note also that this formula applies only to this particular shape, and different formulas are required for other shapes.

One way to execute a Python script using a Chrome extension is to use Native Messaging. This allows the Chrome extension to communicate with a native application, such as a Python script.
Here are the high-level steps to use Native Messaging to execute a Python script:
 1. Create a Python script that performs the desired task.
 2. Create a native application (e.g., a compiled executable) that can be run from Chrome. This application will launch the Python script and communicate with the Chrome extension.
 3. Create a manifest.json file for the Chrome extension that specifies the native messaging host and the allowed Chrome URLS for the extension.
 4. In the Chrome extension code, use the chrome.runtime.sendNativeMessage() method to send messages to the native application and receive responses.
 5. Start the native application and load the unpacked extension in Chrome.
 6. Test the extension and ensure that the Python script is executed as expected.
It's worth noting that using Native Messaging with a Python script requires some level of programming knowledge and experience. However, there are also libraries and resources available to help simplify the process.

Fun Facts about Salamanders and Newts for Kids
 - Salamanders can lay up to 450 eggs at once. Many salamanders are good moms. They stay with their eggs or even wrap each egg in a leaf to protect it. Whew! That's a lot of work!
 - Salamanders often look like tadpoles when they're born. They slowly develop their front and back legs. Unlike frogs, though, salamanders keep their tails.
 - Salamanders' legs are very short. Their tummies drag on the ground when they walk.
 - Salamanders and newts are carnivores. They move slowly so they have to catch slow-moving prey like worms or snails.
 - Salamanders and newts must stay near water. If they get too dry and hot, they'll die. Look for them in wetlands and woodlands, under rocks or near streams.
 - Some salamanders have poisonous skin. Their bright colors tell other animals to leave them alone.
 - North America is home to more salamanders than any other continent.

TUCKER, Ga. – Turkey hen body weight can be controlled without physical feed restriction, but not without effects on egg production and carcass composition, according to research sponsored by the US Poultry & Egg Association. Dr. Michael Lilburn of Ohio State Univ. led the project.
The study involved giving breeder hens free access to low nutrient-dense feed and water allowing the hens to regulate their dietary intake according to their biological needs. The hens were weighed at 24 weeks and placed in pens of heavy, medium and light weight body weight hens. The Heavy, Medium, and Light hens weighed 27.6, 26.3, and 24.3 lbs. at 30 weeks and 25.6, 24.6, and 23.0 lbs. at 42 weeks.
Researchers found the light hens had significantly better hen-day egg production than either the medium or heavy hens, while the heavier hens produced significantly heavier eggs.
Additionally, across all three body weight groups, there was a significant decline in body weight between 30 and 42 weeks of age.

Soil moisture sensors not always accurate
Q. You recently gave me advice on planting pancake myrtle. I dug the planting hole as deep as the container and five times as wide, but didn't do a water percolation test to make sure the planting hole was draining water. I backfilled the hole with a 50/50 mixture of the existing soil and a rich Viragrow compost. However, a soil sensor consistently recorded a "10" (very wet) even for weeks after just one watering.
A. Be careful when purchasing a soil moisture sensor. Sometimes they don't always work.
Before you buy it, get your hand wet and make sure the sensor on the tip is working. A "wet hand" tightly wrapped around the tip should move the needle to or at least near the "10" you mentioned. When the sensor is in the open air and dry, the needle should point to "0" or approach it. Buy only humidity sensors that are working properly.
Pancake myrtles come from the eastern and cold regions of Asia, including northern and central China, Korea, and Japan. When it was introduced to England in the mid-1800s, it did not flower profusely because it was not warm enough. This tree, much like the native Carolina laurel, really likes the warmth of the southern and southeastern United States for flowering.
The reasons it was introduced to the desert is that it likes heat, is quite drought tolerant, and tolerates a wide range of soil alkalinity. Crepe myrtle does not like soils without compost, very intense western and southern slopes without afternoon shade and the low humidity of our desert. In our climates, this tree likes northern and eastern exposure, and regularly amended soils.
If the soil does not drain water very well, raise the soil where you are planting to a height of 12 inches and 4 feet in diameter. Don't plant at the bottom of a ditch unless it likes boggy soil. The soil mound allows the roots of the plant to grow by providing water drainage to the lower soil surrounding the tree.
Q. I am concerned about the appearance of my jasmine vine and rose bushes in my garden. I fed everything with 1 cup of Epsom salts two months ago and fed rose bushes with rose food last month and this month. I watered abundantly before and after the meal. My garden has a drip system that waters for 30 minutes three times a week.
A. It is true that some rosarians like to give Epsom salts to their roses, but that does not excuse the condition of your plants. Epsom salts provide the soil with magnesium in the form of sulfate. Typically, in our alkaline soils, the compost contains enough magnesium to enrich the soil without using Epsom salts. Make sure the soil used in the ridging drains the water.
I don't know where your trees grow, but the preferred landscape exposure for both plants is the east and north sides of a house or wall. Jasmine and roses like soil amended with compost. About half an inch of compost sprinkled on the ground each year is enough to keep these plants healthy and growing at their best.
Just like us, when these plants are healthy, they tolerate heat and cold better. When these plants aren't healthy, they don't tolerate these temperature extremes as much. If the soil is covered with rock and not improved, they will struggle a few years after planting.
What to do? If the soil is amended with compost at the time of planting and the surrounding soil is covered with wood chips, then fertilizer is usually sufficient. Adding compost sprinkled on the soil surface once a year adds a lot of plant nutrients to the soil that is lacking as the rock breaks down. Don't overdo it and keep rocks or wood chips at least 6 inches from the trunk of young plants. Both plants will benefit from annual applications of EDDHA iron chelate in early spring.
Q. Please see the picture of this unhealthy looking palm tree.
A. The photo you sent is not a palm tree although it is called a "sago palm". This plant is also called a cycad. Let's agree to call it a "cycad."
These plants are native to China and Japan and are now cultivated in nurseries around the world. They can handle a lot of difficult locations and poor soils, but they look great when growing in filtered shade and in sandy but enriched soils.
If I had to grow them in a desert landscape, I would place them on the east or north sides of a house or wall, spacing them about 3 feet and 3 feet from walls and buildings. Keeping in mind that they "like" filtered light, I would find a place where sunlight is intermittent. They give a tropical and jungle look to a landscape and should be used where there are a lot of other plants growing.
The soil should be enriched and covered with 3 to 4 inches of wood chip or wood chip mulch and need 5 to 10 gallons of water each time they are irrigated. They are "mesic" in their use of water and should not be watered with the same valve that is used for desert plants like cacti, saguaro, Joshua trees, and ocotillo.
The worst way to grow this plant is on the west or south side with reflected heat, grown in unimproved soils covered with rock and watered like a desert plant. If you can check one of them, your cycad is or will be in trouble.
Q. A few years ago I was fortunate enough to grow a Japanese dwarf pomegranate from a 6 inch cutting. He is now over 5 feet tall. What is a well-cut grenade supposed to look like?
A. The Japanese dwarf pomegranate is an ornamental shrub. It is not appreciated for its fruit. The size is like any other ornamental shrub. Pruning is done once flowering is complete. I assume your ornamental pomegranate flowers for most of the year, so they should be pruned in the winter after the leaves have fallen, just like pruning the pomegranates which are used for their fruit.
The rule of five to six stems that we use for pruning fruit pomegranates is not important if we are using it as an ornamental. This means that you can leave as many stems as you want. As the shrub grows, remove a quarter to a third of the larger stems by pruning them close to the ground. You should remove three or four of the larger stems every two to three years. Pomegranates grown for their fruit are pruned every year during the winter.
Q. Can I use burlap for shade cloth?
A. Do not use burlap as a solid piece in place of shade cloth for permanent shade. It's good for creating permanent shade for people or pets, but not for plants. Pay attention to the amount of heat it traps if it is located too close to humans and animals. Plants are green and need sunlight for photosynthesis. Usually about 60 percent to 70 percent of sunlight. Humans and animals don't need it.
Instead, use a shade cloth. It comes in different shade percentages ranging from around 30 percent to 100 percent. The shade fabric for plants ranges from 20 percent to about 50 percent shade. Plants that flower and produce fruit like tomatoes, peppers, and eggplants need more light than leafy plants: 20 to 40 percent shade. More shade than that interferes with flowering and fruiting.
Plants that only grow leaves such as lettuce, spinach, Swiss chard, and green vegetables can withstand up to about 50 percent shade. After that, they grow poorly because it is too dark.
Most of the burlap I've seen produce a lot more shade than that and wouldn't be a good choice for growing plants.
You can create 50 percent shade from 1-by-2 lumber by omitting any other piece of lumber. These are called tower houses. Likewise, 30 to 40 percent shade can be done the same way, but removing two and leaving every third 1 by 2.

This Agate freeform has been carefully hand-polished to enhance the smooth, glossy lustre of the stone's surface.
This piece displays a large section of marvellous druzy crystals
What Is Amethyst Agate Made Of?
Amethyst Agate is primarily comprised of Amethyst Quartz and Agate
Agate is a member of the Chalcedony group of stones, which is a member of the large Quartz family.
All types of Quartz are composed from silica (otherwise known as silicon dioxide), but differ due to their crystal structures: one form of Quartz is Amethyst, which is included in this particular form of Agate.
What Does Chalcedony Mean?
Chalcedony gems such as Agate are microcrystalline in structure, which means you can't see the crystals inside the stone.
Amethyst Quartz, however, can be observed in crystal form as it is not a form of Chalcedony.
Agate is generally distinguished from other types of Chalcedony due to its banded patterns and translucency: for example, Jaspers tend to be opaque and you cannot see through them if you shine a light through them.
Other types of Chalcedony gemstones include Jasper, Carnelian, and Chrysoprase.
What Is Lavender Amethyst?
Lavender Amethyst is a term used to describe the paler, lilac variety of Amethyst, which tends to come in deep violet varieties.
Other Types Of Agate
Agate comprises a diverse group of stones which can come in many colours and patterns.
Examples include Moss Agate, which demonstrates moss-like patterns, and Cherry Blossom Agate, which displays patterns that look like the flowers of the Cherry Blossom tree.
Eye Agate is a prized form of Agate which displays concentric circles resembling eyes.
Where Does Agate Come From?
Agate in its various forms can be found all over the globe.
This particular piece was sourced from India
Agate History
Agate was first recorded as being discovered in Sicily, near the River Achates, from which it gained its name.
It has been found in many archaeological sites, including in Greece where Agate carvings date back to the Bronze Age.
Agate Crystal Healing Properties
Agate is a renowned stone in the crystal healing world and is useful for bringing harmony, stability, and balance to one's life.
This type of stone comes in many different forms, yet all forms of Agate tend to have a soothing, positive energy which serves to stabilise the body and mind of its user.
Agate Chakras
As Agates are so varied in colour, they tend to resonate with all chakras.
Brown Agates, of which this piece displays elements, resonate with the Root Chakra due to their earthy colouring and thus offer protection and grounding to their users.
Amethyst Agate tends to display light purple, blue, and white tones, and thus can connect to the higher chakras and higher levels of consciousness.
Amethyst Chakras
Amethyst resonates strongly with the Third Eye Chakra and the Crown Chakra, the two highest chakras.
Strongly associated with wisdom, intellect, and creativity, Amethyst is often used to gain inspiration, focus, and clarity of mind, as well as to connect to psychic energies.
Lavender Amethyst also exudes a softer, gentler energy than darker varieties of Amethyst.
Unique Metaphysical Properties Of Amethyst Agate

It has been shown in the literature that a cross-coupled CMOS LC VCO will outperform an equivalent Colpitts VCO. In the case of bipolar devices, the jury is still out. This paper reports a comparative analysis of phase noise (PN), tuning range (TR), dissipated DC power and Figure of Merit (FoM) in cross-coupled and differential Colpitts LC VCOs topologies designed in 180 nm Si-Ge HBT technology for operation around 5 GHz. SpectreRF simulations show that the cross-coupled topology exhibits a minimum PN equal to -108 dBc/Hz, a tuning range of 17.5% and a dissipated DC power of 12.6 mW, with a FoM equal to 204 dB, while the Colpitts topology exhibits a minimum PN over the tuning range equal to -113 dBc/Hz, a tuning range of 21.6% and a dissipated DC power of 14.1 mW, with a FoM equal to 212 dB. This suggests that, for the considered technology, the differential Colpitts can exhibit better overall performance than the cross-coupled VCO.
