Chew On This: Some Gum May Ward Off Ear Infections
When young children get ear infections, parents face an unpleasant choice: dose them with antibiotics and pain relievers, or tough it out.
But certain kinds of chewing gum may help reduce the number of ear infections children get in the first place.
That's chewing gum with xylitol, a natural form of sugar sometimes used in gum and candies because it has fewer calories for its sweetness than table sugar, or sucrose.
Giving children xylitol in gum, syrup or lozenges twice a day reduces the risk of ear infections by 25 percent. The finding come from an analysis by the Cochrane Collaboration, an independent group that combs the medical evidence to figure out what works and what doesn't.
But to get any xylitol benefit, parents and their kids are going to have to work at it. "The catch is how you have to take it," says Rochard Rosenfeld, chairman of otolaryngology at SUNY Downstate Medical Center in Brooklyn, N.Y. The children in the studies chewed the gum five times a day for five minutes. "You can't just sort of swallow this like a pill."
Otitis media is the most common infection in young children, prompting almost 16 million office visits in the U.S. and health care costs of $3.8 billion a year. Children with repeated infections are often referred for surgery to insert ear tubes. So you could see how parents eager to avoid antibiotics and ear infections would be intrigued.
Xylitol has been touted for decades to prevent tooth decay, but that's never really caught on in the United States. Unless you've been reading the labels closely, you might have overlooked gums, such as some varieties of Trident, that contain xylitol.
About a decade ago, scientists got interested in it as a potential treatment for ear infections, when a study showed that xylitol reined in the growth of strep bacteria in petri dishes. Streptococcus pneumoniae has been blamed for up to half of all ear infections.
The four studies considered here were all conducted in Finland from 1998 through 2007. They followed 3,103 children in day care. In three of the studies, healthy children were given xylitol in gum, syrup or lozenges twice a day. Those children saw a reduction in the number of ear infections, with the gum giving better results.
The fourth study gave xylitol to children who already had upper-respiratory infections, which often precede ear infections. Those already-sick children didn't see any reduction in the number of ear infections with the xylitol treatments.
"In Finland,they do this all the time," Rosenfeld says. "It's all over the culture." But he doubts if American parents would be able to stick with "kids chomping away, five times a day", through the cold and flu season.
What's more, ingesting too much xylitol can cause diarrhea and other stomach upsets, and xylitol gum and candy can be expensive.
Some caveats: In all four trials, the gum and lozenges were donated by industry, and the study authors have a U.S. patent for using xylitol to treat respiratory infections. But the authors claimed no conflict of interest. The studies were relatively small, and came mostly from the same labs.
Parents who don't want to have to ask their pediatrician if it's worthy trying xylitol to prevent ear infections can make use of this free consult with Dr. Rosenfeld:
"So if a kid in the course of a year gets four ear infections, you start 'em in October and get 'em chomping the xylitol, instead of four infections you get three. That's a 25 percent decrease. Heck, if I'm a parent I'd rather have an ear infection. Most ear infections don't need antibiotics. You give 'em Tylenol for day or two and they get better on their own."
HIs final word: "To me, it doesn't make sense."

5.9.1 Preparing the MySQL Server
The first step is using MySQL with BLOB data is to configure the server. Let's start by creating a table to be accessed. In my file tables, I usually have four columns: an AUTO_INCREMENT column of appropriate size (UNSIGNED SMALLINT) to serve as a primary key to identify the file, a VARCHAR column that stores the file name, an UNSIGNED MEDIUMINT column that stores the size of the file, and a MEDIUMBLOB column that stores the file itself. For this example, I will use the following table definition:
CREATE TABLE file(
file_id SMALLINT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY,
file_name VARCHAR(64) NOT NULL,
file_size MEDIUMINT UNSIGNED NOT NULL,
file MEDIUMBLOB NOT NULL);
After creating a table, you might need to modify the max_allowed_packet system variable. This variable determines how large of a packet (that is, a single row) can be sent to the MySQL server. By default, the server only accepts a maximum size of 1MB from the client application. If you intend to exceed 1MB in your file transfers, increase this number.
The max_allowed_packet option can be modified using the MySQL Workbench Server Administration screen. Adjust the Maximum permitted option in the Data / Memory size section of the Networking tab to an appropriate setting. After adjusting the value, click the Apply button and restart the server using the Startup / Shutdown screen of MySQL Workbench. You can also adjust this value directly in the my.cnf file (add a line that reads max_allowed_packet=xxM), or use the SET max_allowed_packet=xxM; syntax from within MySQL.
Try to be conservative when setting max_allowed_packet, as transfers of BLOB data can take some time to complete. Try to set a value that will be adequate for your intended use and increase the value if necessary.

Is it time to rethink the way we organise our staff?
Should staff in education institutions be deployed to do only what they are best at, asks Ian Pryce
Ian Pryce
Working from home: Should FE colleges rethink how they organise their staff?
The outsourcing giant Capita was created in 1984 as a division of my non-profit, chartered public sector accountancy body CIPFA. It was quickly subject to a management buyout a few years later and equally quickly established as a major FTSE company. The key to its success was partly down to the rich network of connections it had established in public sector bodies, given that almost all senior finance staff in the public sector are CIPFA members. Success was, even more, a result of the company's ability to unpack administrative processes and identify elements that it could do far more cheaply and efficiently than individual organisations. In an era focused on a mantra of economy, efficiency and effectiveness, this was a perfect business model.
Capita wasn't interested in taking over whole processes, it just wanted to do a slice of a process but do so for every local authority. This is similar to the company GKN, which makes a little piece of almost every car, rather than every piece of a few.
I keep thinking about Capita and GKN in the context of the current debate on hybrid working in colleges. The debate so far seems limited. Much of it is focused on how existing jobs might be repackaged into activity you can do at home, and activity you can do only in college. But this feels like playing chess by only considering one move at a time. The Capita story, and economic theory, suggests that the pandemic is much more likely to create a chain reaction of changes that will be different to those envisaged, especially for support staff.
Blended learning: Eight things that students say work
Teacher burnout: Three ways to avoid it this term
Covid: A quarter of support staff 'worried about job security'
The economist David Ricardo is most famous for his theory of comparative advantage, not least because it works in practice. Essentially if you and I have two activities to do, and we are each better at a different one, then we should specialise. Crucially, the theory says that if you are better than me at both, you should let me do the less valuable activity and you focus fully on the other. It maximises the overall wealth of society.
How can working from home work in colleges in the future?
It is almost certain that we found that the disruption caused by Covid, and the expansion of online learning, customer service and general communication, identified some staff who are brilliant at some activities and less good at others. It is a fair bet that some good face-to-face teachers struggle to achieve as well online, some tutors will be much better than colleagues at online engagement, some staff will come across as more professional in online meetings. We might also now find that some staff are better than others at writing reports, or using systems, or running team meetings from home.
Given evolution and economic theory, isn't it highly likely that we will want to use people's skills to achieve the biggest overall gain? Don't Capita and GKN show us a glimpse of the way roles in colleges might evolve?
For example, it may well be that we decide that face-to-face teaching of 16-18s has a higher value than online delivery. If so, why wouldn't you employ your best face-to-face teachers to work in college five days each week, even if they are brilliant at online delivery, too, and make the less good deliver online from home every day? The assumption that all teachers would do both seems odd. Similarly, if your support staff role has elements that can be now be done at home (data input, data analysis, administration) and elements that need to be done in college or with an employer, why wouldn't the roles be split up so some staff concentrate on the employer elements, others on the college elements, and others who work at home? It particularly makes sense if it reduces the need for office space (one desk not three).
Alongside this is a parallel shift in the way we might measure staff, particularly in support areas. Although we might pretend otherwise, we generally measure people by seeing if they are in work (attendance). A shift to working from home requires an intolerable level of intrusion if you seek to replicate that approach. Instead, it is more likely that metrics of your output will be established, but that generally leads to some negative changes for staff.
First, it is tempting to move to pay by output rather than your time (piece work). Second, it then becomes easier to outsource that work by simply tendering for the output (it drives down pay and you become a commodity). Third, evidence suggests that being out of sight makes you more likely to be overlooked for promotion, and first in line for any job cuts (it being easier to sack someone remote).
The future may not be the bed of roses that many champions of working from home believe, and may not be the hybrid experience many are predicting.
A recent Unison survey of college support staff showed a real concern for their futures and an expectation that life will get tougher for them. Perhaps, as is usually the case, our people are smarter than our forecasters. They can see that, just as individuals want something that works well for them, employers will also want to see an increased bottom line. Where the benefits don't align there will be battles, and the relative balance of power will dictate where a new equilibrium is established.
Who knows, we might even move away from whole-college mergers to massive departmental mergers. If GKN can make a bit of every car, maybe the Bedford College Group can run everyone's staff recruitment process? From home, of course!

Happy New Year! And best wishes for a healthy and prosperous year for all my readers and their families.
On the first day of a new year it seems appropriate to write an exercise based on calendars. Unix provides a
cal command to print calendars. There are several forms:
cal— prints a calendar for the current month
calyear — prints a twelve-month calendar for the specified year; note that year 10 occurred during the time of Christ, so you must specify 2010 for the current year
calmonth year — prints a calendar for the specified month and year; the month is given as a number from 1 to 12
cal -3— prints a three-month calendar for the prior month, current month and next month
The current date is highlighted wherever it appears.

A recent study seems to find a good reason why old people sometimes get cheated and are somehow more vulnerable to fraud.
The study found that a particular region in the brain which actually helps us decide if a person can be trusted, is not as active in old people.
The study which involved analysis of brain scans that were taken while the old and the young made their assessment of photographs of people, found that a region called the anterior insula in the brain which picks up instinctive feelings, was not so active among the older lot.
Most importantly, the old people were unable to recognize certain tell-tale facial hints. Professor Shelley Taylor of the University of California in Los Angeles said, "The older adults do not have as strong an anterior insula early-warning signal; their brains are not saying 'be wary', as the brains of the younger adults are. It's not that younger adults are better at finance or judging whether an investment is good - they're better at discerning whether a person is trustworthy when cues are communicated visually."

FitByte, a device that attaches to your eyeglasses and tracks all phases of food intake, is just one example of how researchers are exploring ways to leverage generic sensors found on consumer devices to develop new and innovative health monitoring applications. To overcome some of the challenges with existing approaches, FitByte employs a multi-modal sensing approach to more precisely capture data in the typically noisy, unconstrained environments in which people consume food.
An onboard camera captures images of the area around the mouth, while gyroscopes monitor jaw motion, high-speed accelerometers located near the earpiece of the glasses detect throat vibrations when swallowing, and a proximity sensor detects hand-to-mouth gestures.
All the sensors used in the device are of the kind commonly found in smartphones and wearables like the FitBit. Extending the capabilities of these generic sensors is key to the commercialization and scalability of tomorrow's health monitoring devices and diagnostic tools.

May 25, 2011 Economic recessions are weaker, expansions are stronger, and economic recovery is faster in U.S. states where people are more optimistic says a new study from the University of Miami School of Business Administration. Further, the effects are stronger in states where people are older, less educated and less socially connected.
"Previous studies have shown that economic conditions affect mood -- people would expect this, it's more obvious," said Alok Kumar, the Gabelli Asset Management Professor of Finance at the University of Miami School of Business and one of the study's researchers. "Our study is unique in that it shows, for the first time, that mood and optimism can directly affect overall economic activity."
In order to determine the link between mood and economic conditions, Kumar, along with Vidhi Chhaochharia and George Korniotis, assistant professors of finance, used several factors to measure mood, optimism and pessimism not influenced by the economic environment. The factors are:
- Weather: Average temperature and cloud cover. Sunny weather triggers the release of serotonin in the brain that causes people to be more alert and cheerful. The opposite is true for bad weather because it releases melatonin that makes people feel tired and down.
- Political Affiliation and Climate: The level of optimism is greater in a region where the local population favors the political parties in power.
- Sports-Related Optimism: People are likely to be more optimistic if their local sports teams have performed well (e.g., wins the Super Bowl or World Series.)
With these factors in mind, the researchers then studied how mood in a U.S. state affects local economic activity. To measure local economic performance, they created a novel index based on state housing conditions, the difference between state unemployment and national unemployment, and income growth. Here are the key findings:
- Peoples' overall good mood and positive outlook can make the impact of a recession weaker, shorter in length and easier to get over.
- Moderate optimism induced by the weather is good for the local economy. A state that is 10 degrees warmer experiences increased economic activity that, on average, is 26 percent stronger. It also experiences recessions that are, on average, 33 percent weaker.
- Mood affects local economic activity in part because it leads to higher retail sales.
These results are surprising because they imply that the economy is affected by non-economic, psychological factors. In an ideal world, mood, would not affect economic activity and retail sales because consumers would only spend more when their income was on the rise versus because the weather is pleasant.
- The impact of mood on economic activity is greater in states where people are older, less educated, less socially connected and therefore more prone to the psychological effects of mood.
"One policy implication of our study is that the development of sports-related infrastructures, like new sports stadiums or other factors that could effect the performance of local sports teams, is certainly something to consider as a way to make a real impact on a local economy for a relatively low cost," said Kumar.

Is there any way to prove that ionic compounds, for instance $\ce{NaCl}$, completely dissociate into singular $\ce{Na+}$ and $\ce{Cl-}$ ions within water by hard experimental evidence?
Besides adhering to the perfect solvation model in theory, I am interested in definitive proof of monoatomic solvation in practice.
How do we know that the ionic crystal lattice isn't only partially dissolved? When the superficial reaction between water and the ionic compound takes place, could it stop at say 10-100 atom microcluster lattices ($\ce{Na/Cl/Na/Cl}$ etc), giving the appearance by standard means that it is completely dissolved?
I am only interested in experimental means of verification, not concepts taken from books.

 $\begingroup$ Osmotic pressure? $\endgroup$ – Ivan Neretin Jul 2 '18 at 21:38
 - $\begingroup$ Possibly, but I am not sure if this thoroughly ensures that there aren't still ultra small lattice clusters emulating ions to a sufficient degree. For example, what if the cluster had only 4 atoms, Na-Cl-Na-Cl? This particle is ridiculously small. How do we know that it doesn't exist? Or rather, larger ones? $\endgroup$ – Michael S. Jul 2 '18 at 21:43
 - $\begingroup$ You wanna check out if Earth isn't flat too? Salty water conducts electricity way better and it wouldn't if salt wasn't dissociated. $\endgroup$ – Mithoron Jul 2 '18 at 21:53

 $\begingroup$ It strikes me as a statistical probability that there will be one Na+ ion next to a Clion without a water molecule in between for some number of femtoseconds. But real "particles" of NaCl floating around... No. Particles of NaCl could be detected by x-ray diffraction, but it is a S/N problem. One cluster of four NaCl "molecules" floating around in 1 ml of water would be undetectable. $\endgroup$ – MaxW Jul 2 '18 at 23:16

 $\begingroup$ _USER_. - Yes, using statistical arguments you could calculate the probability of a 4 "molecule" cluster existing. But chemical properties are about "average" behavior not some probability like winning the lottery 5 times in a row. The chemical behavior of ionic solutions isn't determined by the concentration of the ions, but rather their activity. Within experimental error the plot goes through the origin. You have to realize with $6.023\times 10^{23}$ molecules per mole the state of 3 or 4 molecules just isn't important chemically. $\endgroup$ – MaxW Jul 2 '18 at 23:31
One method is by making electrical conductivity measurements on aqueous solutions of salts. If we take four strong electrolytes:
 - Sodium chloride
 - Potassium chloride
 - Sodium perchlorate
 - Potassium perchlorate
We can measure the electrical conductivities at very low concentrations which allows us to obtain the limiting specific conductivties of the salts (extrapolation to zero concentration).
We will then find that the sum of the limiting conductivity of sodium chloride and potassium perchlorate will be the same as that of potassium chloride and sodium perchlorate.
This is because the limiting conductivity of a strong electrolyte salt is the sum of the contributions of the cations and anions. This allows us in an indirect way to show that some salts can totally dissociate when very dilute.
 - $\begingroup$ I think this is a good answer, but I was wondering whether limiting conductivities imply true ionic dissociation in practice even if the measurements are the same for different species. I understand logically the sum of the parts equals the whole, I am still trying to confirm the true nature of the parts. So, far this is a good answer. I am nearly satisfied. (Upvoted) $\endgroup$ – Michael S. Jul 3 '18 at 15:12
Another method is to look at boiling point elevation (using this to study dissociation is called ebulliscopy). In theory (think ideal liquid), boiling points increase linearly with the molality of dissolved non-volatile components. Thus change in boiling point of water is equal to the ebulliscopic factor times the solution molality. This allows the estimation of a value 'i' that denotes the moles of dissociated ions vs the moles of the dissolved substance.
For instance, i=1 for sugar (no dissociation), i=1.9 for NaCl, showing that it is highly dissociated, i=2.3 for calcium chloride, etc..
This would indicate the likely conclusion that NaCl does not completely dissociate with the resulting ions randomly dispersed throughout an completely disordered solution (there is probably some local structure around the ions), but it's close.
(NOTE: Alternatively, you can look at freezing point depression, which for low concentrations of solute is a linear function of molality, also.)
Taking aside modern methods on nanochemistry, many experiences can be used. The mixture will have very different properties depending on which is the final particle size, from entropy changes to conductivity changes.
You can argue in terms of conductivity just by the verification of the law of independent ionic molar conductivities. Salts must dissolve completely for the law verification.
The halfwave potential (polarography) is quite independent of the counterion.
In essence, almost anything that turns to be independent of the counter ion is a good proof (from electric methods above, to ionic chromatography, to selective electrodes etc.)
One of the simpler evidences can be the diffusion speed, which is easily modeled and measured and turns to be compatible which small particle size. Of course you can say that the models are not exact and small differences are hard to predict. Let's consider we just bounded the possible sizes to very few ions clusters. In such case you can measure (for example) frequency dependent dielectric permittivity and confirm that there are not relaxations at frequencies compatibles with molecular rotations.
By the way, thousands of good predictions are made monthly requiring such consideration (dissolution to individual ions), and do not forget nanochemistry.

Model LDT Leak/Over Temperature Detection Relay
Shaft Seal Leak and Stator Temperature Monitor
The Dwyer Model LDT is used to monitor the shaft seal and the stator temperature of a submersible pump to detect a leak or over temperature before pump failure. A leak is detected by sensing the status of a float or conductivity switch installed in the seal cavity. When this resistance drops below the set sensitivity, the output relay energizes and the LED indicator illuminates. When the seal failure condition clears, the relay automatically resets. A normally closed temperature switch mounted on the stator detects over temperature. The temperature safety feature incorporates a bistable relay that retains its position during power loss and latches on until the remote reset button is pressed. The LDT has adjustable leak sensitivity from 1k to 35k ohm. Installation is made simple with a surface mount configuration.
Dwyer Model LDT Specifications
- Power Requirement:120 VAC, 50/60 Hz.
- Power Consumption:4 VA (approximate).

Aqua Max Sport Fish 500, 3/16 Inch(4.8mm) Extruded Floating Fish Food For Trout, Bluegill, Hybrid Striped Bass, Feed Trained Largemouth Bass, Yellow Perch, Sunfish, Crappie, Red Drum, and Many Other Species, 18 Ounces
$19.95 - $18.95
(as of May 20,2022 08:23:39 UTC – Details)
AquaMax products are formulated to be high energy, nutrient dense diets. These highly-digestible diets enable fish to more efficiently utilize nutrients which in turn reduces the biological load in the water column. The extruded pellets reduce the amount of fine feed dust material which helps maintain water quality by minimizing feed waste. Excessive feed fines in water can lodge in fish gills in some species and attract bacteria and fungus. By reducing these feed fines, AquaMax fish diets provide an added health benefit to fish.Ingredients used in manufacturing Purina fish diets are the highest quality in order to maintain consistent nutrition from bag to bag. "Rule of thumb" The lowest priced feed usually does not produce the lowest feed cost per unit gain- Purina feed may cost more per pound than other brands, however because it is higher in nutrients, you actually have to feed less to your fish – which makes Purina fish feeds a tremendous value
Extruded Floating Pellets, 3/16″ (4.8mm). Precision Extrusion Reduces Fines For Less Waste Which Results In A Better Feed Conversion Ratio(FCR) And Water Quality.
A High Energy, Nutrient Dense Diet For Trout, Hybrid Striped Bass, Bluegill, Sunfish, Yellow Perch, Crappie, And Red Drum, Other Carnivorous Species.

Amsterdam, The Netherlands – Premiering at the Eyefilm Museum in Amsterdam on October 14th, the film Tulipa received a standing ovation from more than a hundred participants who joined the gala event including the delegation from the Philippine Embassy The Hague and humanitarian officials from other countries. Tulipa is the first Filipino film shown at the historic cultural and film center Eyefilm Museum.
TULIPA is a film about Filipino LGBTs who sought a life outside the Philippines to assert their rights to gender equality, representation, and most importantly, freedom of expression. The film features personal experiences and life stories about survival, hope, and the continuous struggle of Filipino LGBTs living in the Netherlands. One of the most pressing campaigns explored in the film is the call to pass the SOGIE (Sexual Orientation and Gender Identity Expression) Equality Bill, which aims to legalize measures to prevent various acts of discrimination against people based on their sexual orientation, gender identity, or expression.
This film is a product of collaboration with The Filipino LGBT Europe Foundation, the Philippine Embassy The Hague, The Netherlands Embassy Manila, Commission on Human Rights Philippines, the ASEAN SOGIE Caucus, and MUJER LGBTQ+.
Senator Risa Hontiveros gave a recorded welcome speech during the event highlighting the importance of passing the SOGIE Equality Bill. "SOGIE Equality is an important step towards universal health care, universal quality education, and livelihood for all. This is not just the fight of the LGBTQIA+ community but also our fight to build the Philippines we aspire for," Hontiveros says.
Chairperson and film Executive Producer Chris Sta Brigida Kopp said in his welcoming remarks that Filipino LGBTQ+ migrants do not just leave the Philippines due to financial reasons alone, but also due to the lack of legal protection in the country. "Filipino migrants have aspirations to go back home, but the lack of legal protection stops many in our community from going home. In most cases, coming back home could mean giving up the rights and protection that allowed them to grow and prosper while living overseas," he adds.
Highlighting the struggles of Filipino LGBTQI+ migrants is an important step in bridging the connection among Filipinos around the world and how laws in the Philippines ultimately impact not just Filipinos living in the country but also Filipino migrants.
"As I journey in the fight for the SOGIE Equality Bill along with my peers in the Philippines, I realized that it seems we have forgotten about the biggest export of our country…our people," film director Rhadem Musawah says.
"They were always invisible in the narrative of our equality movement back home. Leaving their home country because of these inequalities in the Philippines, the agony they go through from leaving to living. That is why we made this short film, not to entertain people but to start a conversation of inclusion, to spark awareness of the aspirations of Filipino LGBTIQ+ in the diaspora."

Child Honouring is a philosophy—a vision, an organizing principle, and a way of life—the children-first way of sustainability.
It starts with three givens:
The primacy of early years—early childhood is the gateway to humane being.
We face planetary degradation that is unprecedented in scope and scale—a state of emergency that most endangers the very young, and that requires a remedy of equal scale.
This crisis calls for a systemic response in detoxifying the environments that make up the world of the child.
Child Honouring is a children-first approach to healing communities and restoring ecosystems. It views how we regard and treat our young as the key to building a humane and sustainable world. It is a novel idea—organizing society around the priority needs of its youngest members.
The essence of the vision is expressed in A Covenant for Honouring Children and its underlying principles.
Its spirit is invitational—a call to imagine and create a diversity of child-friendly cultures. A child-honouring society would show love for its children, and thus for all of us, in every facet of its design and organization.

Proving?R² Using Chains, a Ruler, and Sixty Seconds
In this brief video, Minute Physics shows a visual proof demonstrating why?R² gets you the area of a circle. By using various lengths of chain laid into a circular shape, you can make a triangle from the circle -- and from there it's a hop, skip, and a trigonometry jump to proof of your circle's area. Check it:
As Minute Physics explains in the YouTube video description, this video is based on a paper by Russell Jay Hendel of Dowling College: Proof Without Words: Area of a Disk is?R² (PDF link).

Reality Selling Video Case Problem: Ecolab
If I were in the position of Chris Wylie and find serious health problems in my customer's kitchen, I would have used the following strategies:
- Informative: this strategy will be used to inform the client about the possible health hazards in his/her kitchen by examining the problems in kitchen beforehand.
- Persuasive: the strategy will be used to perused customer to avoid particular health problem in his/her kitchen and use the suggested measure to fix the issue.
These two strategies will be applied using 5 key guidelines:
- Make need oriented presentation;
- Get customer involved;
- Provide him single solution;
- Create sense of the suggested solution;
- Provide solution to client using best media
In order to make presentation to customer, I will use multimedia presentation in power-point and will include in my presentation slides all possible aspects of the suggested measure.
While conducting survey in client's kitchen, objections and their solution include the followings:
- Customer might be concerned about the privacy of the methods used at his kitchen, thus a confirmation of maintaining secrecy on to the processes used at his kitchen will be provided.
- Secondly, when providing the solution and to perused client to buy the suggested measure, he might be reluctant on whether the suggested measures will exactly solve the problem; in such situation, he can be convinced using existing case studies in which the similar problem was solved using the same suggested measures.
The seven steps of sales process which Chris Wylie uses in his demonstration are as under:
- first of all, he gathers the basic knowledge of the product to customers i.e. the knowledge about the main features of product or service;
- in the next step, he looks to find new customers for his product or service;
- in third step, he starts building relationships with customers;
- in 4th step, he makes need assessment as to why the client should purchase the product or service;
- after making needs assessment, Chris makes demonstration to client about his offering focusing on the benefits his product or service offers and not on features of product;
- Chris makes his demonstration successful by making a strong close. This is done by looking into the hindrances if the offered product or service is not bought by customers;
- Finally, he makes persistence touch with customer in such a way as to win an order rather than becoming bothersome for the customers.
In situations where it becomes difficult for Chris to demonstrate the product or service to client, as for instance in case of intangible services or large products, the following method could be used:
He can take the customer to a place where actually the offered product or services are being used with good results. In this way it would become easy for him to convince customer for his offering.

The wiki article Simulating Pointer Events introduced a way to simulate pointer events within an application. However, sometimes a program may need to send pointer events to other applications. This article describes how to simulate pointer events by RWsSession::SimulateRawEvent(), and explains why it is impossible to send pointer event to a background application by RWsSession::SendEventToWindowGroup().
The RWsSession::SimulateRawEvent() can be used to simulate pointer events, i.e. send pointer events to the foreground application. Assume that the phone is in portrait mode, then the following code can simulate a touch operation on the "Options" CBA button area. If the foreground application has the "Options" CBA button then its options menu will be popped up.
TPoint p(60,600); // within the "Options" CBA button area
TRawEvent event;
event.Set(TRawEvent::EButton1Down, p.iX, p.iY);
iCoeEnv->WsSession().SimulateRawEvent(event); // SwEvent
event.Set(TRawEvent::EButton1Up, p.iX, p.iY);
Source Code
Full example:
How to use it on emulator:
 1. Build the application for winscw and then start the emulator
 2. Start the application and then press the "Multi-task" key (also called the Menu key),
How to use it on target:
 1. Sign the HelloWorld_gcce.sis with a certificate that can grant SwEvent capability
 2. Install the signed installation package on the phone and then start it.
 3. Press the "Multi-task" key
You can see the app sends itself to background and then the foreground application (the Main menu) pops up its options menu.
Many developers tried to send pointer events to a selected application by RWsSession::SendEventToWindowGroup(), but always the target application crashed with KERN-EXEC 3 panic.
To know why it is a Mission Impossible to send pointer events in this way, we shall first understand the convention between CONE and Window Server:
 1. When a window-owning control (CCoeControl) is constructed the address of the control is used as the handle of the window.
 2. When there is a pointer event the Window Server decides which window shall handle it, and then assigns the window handle to the event.iHandle, and then sends the event to the app that owns the window.
 3. When the app CONE received the event, it casts the event.iHandle to a CCoeControl pointer and then call pointer->HandlePointerEventL(event);
So if the code looks like this:
TWsEvent event;
event.SetHandle(0); // "what the handle is? Anyway clear it..."
TPointerEvent& pointerEvent = *(event.Pointer());
pointerEvent.iType = TPointerEvent::EButton1Down;
pointerEvent.iParentPosition = TPoint(0,0);
pointerEvent.iPosition = TPoint(10,10);
pointerEvent.iModifiers = 0;
ws.SendEventToWindowGroup(...); // // send the event to app1
When the app1 receives the event the bad thing will happen:
// CONE code
CCoeControl* ctrl = reinterpret_cast(event.Handle());
ctrl->HandlePointerEventL(*(event.Pointer())); // KERN-EXEC 3 because ctrl equals NULL
The Window Server is in charge of all the windows so it knows what the iHandle should be, but you don't know, so "Window Server's score:100. Yours:0!"
PS: RWindowGroup::Child() can return the client handle but we can not take it for granted that it is a CCoeControl pointer.
The CONE source code included in ER5 SDK (log-in required).

When Is the MUGA Scan More Useful Than Other Tests?
When Is the MUGA Scan More Useful Than Other Tests?
A multigated acquisition scan is used to determine whether blood is flowing through the heart properly, which allows physicians to localize damage to the heart to a single location, according to About.com. MUGA scans are conducted on cancer patients to assess damage to the heart caused by chemotherapy, says Cancer.net.
By being able to centralize damage to one area, physicians are able to diagnose heart issues and move along with treatment in a less experimental fashion, according to About.com. A MUGA scan utilizes a moving image to scan the ventricles of the lower chambers of the heart, the chambers that are most responsible for pumping blood through the heart. The scan is noninvasive, allowing it to be used repeatedly where other tests require invasive procedures.
The patient is injected with specialized red blood cells to highlight certain areas in the image, as claimed by About.com. Technetium 99, a radioactive substance, is added to the red blood cells in order to make those highlights appear. The red blood cells localize themselves to the chambers of the heart while the gamma camera the patient is placed under picks up on the radiation the red blood cells give off. The radiologist uses the outline the red blood cells create in a specialized computer software to create a moving image of the heart pumping blood.

DescriptionFrom April to June 2020, the research program 'If I can't dance, I do not want to be a part of your revolution', focused on building connections between the University of the Underground HQ in Amsterdam and Tbilisi whilst bringing together multidisciplinary practitioners and early career researchers investigating disciplines such as dance and its potential in building organised communities and reinventing politics.
Of interest to the research bureau 'If I Can't Dance I Don't Want To Be Part Of Your Revolution' were the historic collisions between dance, politics and organized communities. The research group considered how politics and dance can inspire one another and what would happen if they merge. How do dance parades undermine power structures or create a blueprint for new ones? What can politicians learn from ballerinas or 'dancing' boxers and vice versa? How can new forms of debate develop from voguing and how will new systems of government emerge from modern dance or contemporary jazz?
Due to covid 19, the programme had to take place online instead of in Tbilisi and Amsterdam and therefore the result of these investigations will also be presented online.

Google Code-In (GCI)
Google Code-In is a project like Google Summer Of Code. But this time, there are not university students, but 13-18 years old people the targeted audience. Previous Code-In organisations: * Code-In 2010 * Code-In 2011 * Code-In 2012
Code-In differs from Summer Of Code also in not having a single task for one student, but creating a large number of tasks and then having the students pick the ones they want to work on. Thus, it is not suited for large projects, but for small tasks like writing howtos, fixing bugs.
All the tasks should be completable within hours or up to three days. To get an idea of how much a single task should be and what kind of they could be, look at this page. There is [information from Google] ( about what is suitable as a task for Code-In.
NetBSD participated in Code-In 2012. You can find the results here. The status of integrating Code-In's work to NetBSD can also be read there.
Goals as stated by Google
 1. Code: Tasks related to writing or refactoring code
There were some tasks left, and there might be more ideas over the following year to participate in Code-In 2013 again.

the library, I have things like this:
defs = function(params) return BasicElem('defs', params) end;
So, 'defs' is a function, which takes a single parameter (typically a table), and it constructs an instance of the BasicElem 'class', handing in the name of the element, and the specified 'params'. And that's that…
BasicElem has a function 'write(strm)', which knows how to turn the various values and tables it contains into correct looking SVG elements and attributes. It's all right there in the write() function. In addition, it adds a couple more tidbits, such as the attr() and append() functions.
Now that these basic constructs exist, what can be done? Well, first off all, every one of the SVG elements is covered with the simple construct we see with the 'defs' element. How might you used this:
 local doc = svg {
 width = "12cm",
 height= "4cm",
 viewBox="0 0 1200 400",
 }
 doc:append('rect')
 :attr("x", 1)
 :attr("y", 2)
 :attr("width", 1198)
 :attr("height", 398)
 :attr("fill", "none")
 :attr("stroke", "blue")
 :attr("stroke-width", 2);
 local l1 = line({x1=100, y1=300, x2=300, y2=100, stroke = "green", ["stroke-width"]=5});
 local l2 = line({x1=300, y1=300, x2=500, y2=100, stroke = "green", ["stroke-width"]=20});
 local l3 = line({x1=500, y1=300, x2=700, y2=100, stroke = "green", ["stroke-width"]=25});
 local l4 = line({x1=700, y1=300, x2=900, y2=100, stroke = "green", ["stroke-width"]=20});
 local l5 = line({x1=900, y1=300, x2=1100, y2=100, stroke = "green", ["stroke-width"]=25});
 --doc:append(r1);
 doc:append(l1);
 doc:append(l2);
 doc:append(l3);
 doc:append(l4);
 doc:append(l5);
In this case, instead of doing the 'inlined table document' style of the first example, I'm doing more of a 'programmatic progressive document building' style. I create the basic 'svg' element and save it in the doc variable. Then I use the 'append()' function, to create a 'rect' element. On that same element, I can use a short hand to add it's attributes. Then, I can create separate 'line' elements, and append them onto the document as well. That's pretty special if you need to construct the document based on some data you're seeing, and you can't use the embedded table style up front.
There are some special elements that get extra attention though. Aside from the basic table construction, and attribute setting, the 'path' element has a special retained mode graphics building capability.
 local p1 = path {
 fill="red",
 stroke="blue",
 ["stroke-width"]=3
 };

 p1:moveTo(100, 100);
 p1:lineTo(300, 100);
 p1:lineTo(200, 300);
 p1:close();
 local doc = svg {
 width="4cm",
 height="4cm",
 viewBox="0 0 400 400",

 rect {
 x="1", y="1",
 width="398", height="398",
 fill="none", stroke="blue"};

 p1;
 }
In this case, I create my 'path' element, and then I use its various path construction functions such as 'moveTo()', and 'lineTo()'. There's the full set of arc, bezier curvs, and the like, so you have all the available path construction commands. Again, this works out fairly well when you are trying to build something on the fly based on some previously unknown data.
There's one more important construct, and that's string literals. There are cases where you might want to do something that this easy library just doesn't make simple. In those cases, you might just want to embed some literal text into the output document. Well, luckily, Lua has a fairly easy ability to indicate single or multi-line text, and the BasicElem object knows what to do if it sees it.
 g {
 ['font-family']="Arial",
 ['font-size']="36",
 [[
 <text x="48" y="48">Test a motion path</text>
 <text x="48" y="95" fill="red">'values' attribute.</text>
 <path d="M90,258 L240,180 L390,180" fill="none" stroke="black" stroke-width="6" />
 <rect x="60" y="198" width="60" height="60" fill="#FFCCCC" stroke="black" stroke-width="6" />
 <text x="90" y="300" text-anchor="middle">0 sec.</text>
 <rect x="210" y="120" width="60" height="60" fill="#FFCCCC" stroke="black" stroke-width="6" />
 <text x="240" y="222" text-anchor="middle">3+</text>
 <rect x="360" y="120" width="60" height="60" fill="#FFCCCC" stroke="black" stroke-width="6" />
 <text x="390" y="222" text-anchor="middle">6+</text>
 ]];
 path {
 d="M-30,0 L0,-60 L30,0 z",
 fill="blue",
 stroke="red",
 ['stroke-width']=6,

 animateMotion {values="90,258;240,180;390,180", begin="0s", dur="6s", calcMode="linear", fill="freeze"}
 }
 }
Notice the portion after the 'font-size' attribute is a Lua multi-line string literal. This section will be incuded in the form document verbatim. Another thing to notice here is that 'path' element. Although path is specialized, it still has the ability to have attributes, and even have child nodes of its own, such as for animation.
Another case where the literals may come in handy is for CSS style sheets.
 defs {
 style {type="text/css",
[[
 .land
 {
 fill: #CCCCCC;
 fill-opacity: 1;
 stroke:white;
 stroke-opacity: 1;
 stroke-width:0.5;
 }
]]
 };
 };
The 'style' element is well known, but the format of the actual content is a bit too specific to translate into a Lua form, so it can simply be included as a literal.
Well, that's the beginning of this journey. Ultimately I want to view some live graphics generated from data, and send some commands back to the server to perform some functions. At this point, I can use Lua to generate the SVG on the fly, and there isn't an SVG parser, or Javascript interpreter in sight.

Merry Christmas, Happy New Year and Happy Holidays to All from the VoIP Hurricane Net Management Team!
Hello to all..
On behalf of the VoIP Hurricane Net Management Team, we would like to take this opportunity to wish everyone a Merry Christmas, Happy New Year and Happy Holidays to all. Thanks to all of you for your support of the VoIP Hurricane Net during 2017.
The 2017 Atlantic Hurricane Season was the most active year for the VoIP Hurricane Net since the mid-2000s. There were 4 formal activations of the VoIP Hurricane Net for the year. The formal VoIP Hurricane Net activations included Hurricane Harvey, Hurricane Irma, Hurricane Maria and Hurricane Nate.
Hurricane Harvey tracked across Eastern Texas making landfall in Rockport Texas. Harvey produced major hurricane force conditions and several weather stations recorded measured wind gusts over 100 MPH. These winds caused significant, tree, wire and structural damage as well as a significant storm surge for the area around Rockport Texas and the immediate coastal areas. As Harvey weakened, his track slowed significantly and tapping into Gulf of Mexico moisture it caused tremendous rainfall amounts across portions of Texas including greater than 50″ of rain in the Houston Texas area and greater than 50″ of rain in the Beaumont, Graves and Port Arthur Texas. This led to catastrophic river, stream and urban flooding in these areas with tremendous damage. While Harvey was a tropical storm as this occurred, the VoIP Hurricane Net maintained a listening watch for several days handling a number of rain gauge, flooding and even a small number of rescues by informing the United States Coast Guard of the needs of a small number of residents. Harvey would be the start of a very active period of hurricanes in the Atlantic and Harvey was the first major hurricane to impact the US in 12 years.
Hurricane Irma formed during and shortly after Harvey's impacts in Eastern Texas. Irma would cause massive destruction on the island of Barbuda where wind gusts as high as 155 MPH occurred there before the wind instrument malfunctioned. Many of the structures on Barbuda were destroyed by Irma. Some damage was also reported on the island of Antigua to trees and power lines and a few structures by Amateur Radio Operators but Antigua escaped the worst of Irma's wrath. The islands of Anguilla and St Maarten/St Martin sustained very significant damage to trees, power lines and structures including storm damage to their airports. The Anguilla Department of Disaster Management weather station maintained by VP2EL-Larry had a sustained wind of 82 MPH with wind gusts to 117 MPH before that wind instrument failed. St Thomas in the US Virgin Islands had sustained winds of 82 MPH with gusts to 113 MPH before that instrument failed and had similar damage to Anguilla and St Maarten/St Martin. These areas would take weeks to months to recover from the damage brought by Irma. Irma would then go on to batter much of the state of Florida with widespread tree and power line damage and damage to structures from both the damaging winds and storm surge. Flooding from heavy rainfall was also an issue particularly in inland portions of Florida and where storm surge with the heavy rainfall caused further flooding issues. Close to 6 Million people were without power in Florida for numerous days and some would not get power back for over a week. The VoIP Hurricane Net was active through these various landfalls and got a number of reports from Amateur Radio Operators and SKYWARN Spotters in Florida and into Southern Georgia and included damage photos posted to the VoIP Hurricane Net Facebook page with credit given to those that shared storm damage photos.
Hurricane Maria formed shortly after Irma and would affect the Caribbean islands a bit south and west of the path of Maria. The island of Dominica would take a direct hit from Maria with significant damage to trees, power lines and structures from high winds, storm surge and heavy rainfall caused landslides in some of the villages on Dominica. Reports monitored by the Caribbean Emergency Weather Net were relayed by J69DS-Frans into the VoIP Hurricane Net along with reports monitored off of modern social media were collated and sent into WX4NHC, the Amateur Radio station at the National Hurricane Center. Many Amateur Radio Operators on the island of Dominica suffered significant property losses yet continued to operate their Amateur Radio stations during and after the storm to support their communities and to relay information about the state of the island. The same would be said for the Amateurs in Puerto Rico and the US Virgin Islands and other Amateur Radio stations affected by hurricanes this season. As Maria rolled into the US Virgin Islands and Puerto Rico significant infrastructure damage occurred in these areas causing significant communications and power issues. Wind gusts of over 100 MPH were recorded in Puerto Rico as Maria tore through the island. NP3OD-Francisco, long-time VoIP Hurricane Net participant, gave live updates and reported damage to his home and neighborhood. KB2WUS-Francisco provided many relayed damage reports and information from Puerto Rico as well providing high situational awareness. NP3OD-Francisco has managed to support efforts with his local Red Cross despite the damage at his location and is holding up well. He lost electrical power and had trouble at times finding gas for his generator but he maintained running water at his residence throughout the event. The infrastructure damage from Maria in Puerto Rico required the ARRL Force of Fifty mission supporting Red Cross.
A complete archive of the different Hurricane responses across the Amateur Radio community from Harvey, Irma and Maria can be found at the following links:
Hurricane Nate was the last formal VoIP Hurricane Net activation. Nate's main impacts were across the Southern Mississippi and Southern Alabama gulf coast with storm surge flooding, heavy rainfall causing river and stream flooding and damaging wind gusts and tornadoes from the convective bands of the hurricane. Impacts across Southeast Louisiana were negligible as the main conditions were along and to the east of the center leaving Louisiana on the weaker end of the storm system. A number of reports were handled from US Gulf Coast region along with interaction with local/regional SKYWARN teams out of the Mobile Alabama NWS Forecast Office and the Crescent City Amateur Radio Group (CCARG) in New Orleans Lousiana. It was also the first time experimenting with the Zello application using Amateur Radio procedures working with the CCARG team and will be something that will be reviewed as a use case to cast a wider reach to gather information for both Amateur Radio and non-Amateur Radio people that could provide information during hurricanes.
A complete archive of reports compiled via the VoIP Hurricane Net can be seen in our report viewer in the following link:
As occurs yearly, we did support WX4NHC, the Amateur Radio Station at the National Hurricane Center with the WX4NHC Communications Test at the start of the 2017 Atlantic Hurricane Season. As our main client, we appreciate WX4NHC's support of our net and thank WX4NHC Coordinators, Julio Ripoll-WD4R and John McHugh-K4AG for their support. They have been an incredible partner with the VoIP Hurricane Net dating back to the net's inception in the 2003-2004 timeframe. We also had another successful SKYWARN Recognition Day event on the home of the VoIP Hurricane Net, Echolink conference: *WX-TALK* Node: 7203/IRLP 9219. Many NWS offices rotated on the system making contacts with Amateur Radio Operators and SKYWARN Spotters from around the country thanking them for their support as well as making contact with different NWS offices around the country.
As we move into next year, we will again have a presence at the 2018 National Hurricane Conference which will be in Orlando Florida. As we move into 2018, we will look at doing training presentations particularly on the non-hurricane season months in 2018 and continue the question of the week format for the weekly nets and possibly do a few training sessions during the weekly nets that we have during the 2017 Atlantic Hurricane Season. We will also look at boosting more stations and contacts within the affected areas of hurricanes to provide critical surface reports to WX4NHC. We will also be factoring in many lessons learned from the 2017 Atlantic Hurricane season for net activations in 2018 and this information will be factored into an updated NCO training for the 2018 Atlantic Hurricane Season. We will also be looking further at how stations outside of the affected area can assist with weather station, public safety and social media monitoring to provide more information for situational awareness and disaster intelligence during hurricane net activations and further investigate the experimentation with Zello utilized during Hurricane Net with CCARG. We would like to ask folks that might be interested to be a net control for the weekly/monthly VoIP Hurricane Prep Net and for net activations to please contact me directly as a reply to this email or at _EMAIL_
We look forward to working with everyone again in 2018. The next VoIP Hurricane Prep Net will be will be Saturday January 6th, 2018 at 8 PM ET/7 PM CT/6 PM MT/5 PM PT which also equates to 0100 UTC Sunday. The net will meet monthly through May and then become weekly during the Atlantic Hurricane Season. We again wish all of our reporting stations, net controls and supporting stations that listen to the VoIP Hurricane Net a Merry Christmas, Happy New Year and a Happy Holiday season!

The Circumpolar Biodiversity Monitoring Program's Marine Scoping Workshop was held at the Greenland Institute of Natural Resources in Nuuk, Greenland November 5-7, 2019. The Program has been working with partners across the Arctic to enhance long-term marine biodiversity monitoring efforts, led by the Marine Steering Group. This culminated in the Arctic Marine Biodiversity Monitoring Plan (CBMP-Marine Plan) in 2011, followed in 2017 by the State of the Arctic Marine Biodiversity Report. This Marine Scoping Workshop was conducted to consider revisions to the CBMP-Marine Plan based on new information, key findings, expert advice, and national reports and to inform the development of a new coordinated plan for the program's next phase.
Megan Sheremata, 2019 IASC SHWG Fellow, participated on behalf of IASC (funded by a cross-cutting activity), and contributed input based on her research experience within Indigenous-led marine monitoring networks in the Hudson Bay Basin. Her input emphasized a knowledge co-production approach to monitoring, with greater emphasis on collaborative methodologies at all stages so that biodiversity assessments can better serve the information needs of Indigenous land-users and decision-makers. Megan has submitted a report to IASC leadership and the Marine Working Group, with recommendations for coordinating with the CBMP Marine Steering Group.


What Is Marketable Surplus?
by Ronald Kimmons
By describing something as "marketable," people in the business world mean that it is fit to sell on the market. Surplus is the amount of product that a company manufactures or produces in excess of what is necessary to continue operations. Marketable surplus is a term that agriculturalists use to refer to a specific type of surplus that farmers and ranchers deal with.
Farming requires investment. Farmers must make financial investments in labor, tools, fertilizer and land. They must also invest in seeds. If it is the farmer's first year to grow a certain crop, he probably has to purchase seeds from someone else. A farmer must also invest in the form of personal labor. The marketable surplus for an agricultural entrepreneur is the surplus of produce that exists after the point at which he can make back any money he paid to laborers or used to buy tools, fertilizer and land. If he takes some of the crop for his own family's consumption and to use as seed for the next year, he must account for this as well before calculating the marketable surplus. In this way, marketable surplus is what a farmer makes for his personal labor.
Marketable surplus is the portion of a harvest that a farmer can sell on the market to earn a profit. With this profit she can reinvest into farming operations by purchasing more land or better farming equipment. She may also simply save this profit or use it to purchase personal items.
In agriculture, farmers and ranchers can never know exactly how much product their efforts will yield for a particular season until it is over. For this reason, a farmer may not know what his marketable surplus will be until he actually harvests his fields. This uncertainty of the size of a crop's marketable surplus lends a certain level of uncertainty to the farmer's income expectations.
Marketed Surplus
Another term that closely relates to marketable surplus is marketed surplus. In some cases, these terms may be interchangeable. The principal difference is time perspective: marketable surplus is produce that a farmer currently has on hand to take to market to earn a profit, while marketed surplus is what she has already taken to market to earn a profit.

— as Boakai Promises Improvement
Liberian farmers have underscored the need for the government to provide more support towards the agricultural sector of Liberia.
The farmers said considering the numerous challenges that still exist within the sector, there is a need for the provision of adequate incentives.
The farmers' call comes at a time when Liberia's new President, Joseph Nyumah Boakai, has declared agriculture as a priority.
Boakai delivered his first State of the Nation address on Monday, January 29, promising to improve agriculture. But critics have said that the President's address didn't provide a detailed explanation of how he is going to address challenges within the sector that he wants to focus more on.
Aside from climate change, Liberia's agriculture is also grossly undermined by lack of or limited affordable farm inputs, limited access to finance, poor access to energy for value addition, poor road networks, and high transportation costs.
Speaking to the Daily Observer in an exclusive interview, Henry Harris, a farmer in Bong County, said that many farmers in his county are still faced with many challenges including the lack of access to extension services.
"We are on the farm and we are suffering. Our crops are spoiling due to the lack of support. We don't have access to tools, fertilizers and seeds. We are happy to hear that this new leader has interest in agriculture," Harris said.
He said that there is a need for the government to invest more in research and extension.
Liberia launched the new extension policy last year, but the funding required to support extension and research is not yet available.
President Boakai did not make any specific mention of addressing the issue of poor extension in his first Annual Address to the Legislature. However, he has spoken about improving extension services for farmers before.
According to Harris, the Ministry of Agriculture and the Central Agriculture Research Institute (CARI) are not helping many of the farmers in his county.
"My farm is located right near the Research Institute but we the farmers are suffering. We are hearing that the Ministry is helping some farmers but we want them to reach us too," he said.
Harris also mentioned that the market still remains a serious constraint.
"The market is still hard as we are not maximizing our profits. The market is in need of a storage facility to preserve the vegetables we produce," he explained.
Roseline Zokpoah, a farmer from Nimba County informed this paper that the deplorable road condition is seriously hampering the productivity of farmers in her community.
"We are encountering a lot of difficulties to take our produce to the market," she said.
However, President Boakai has disclosed plans to improve value addition and roads in order to enhance the incomes of smallholder farmers.
His ARREST (Agriculture, Roads, Rule of Law, Education, Sanitation and Tourism) agenda spell out his priorities for the country over the next six years.
Boakai has repeately said that Liberia is endowed with abundant natural resources that can provide economic agricultural opportunities for the citizens. He however admits that while it is true that the country is blessed with the available arable land the vast portion of the land is being underutilized.
"My government is committed to harnessing the right resources and strengthening collaboration with international partners to support local farmers," he stated.
He further mentioned that Liberia as a country is holding discussions on climate change mitigation, further emphasizing the importance of international partnerships for sustainable agricultural production and development.
Agriculture in Liberia is still being hugely supported with funding from international partners.
Boakai once served as Director for the defunct Liberia Produce Marketing Corporation and later served as a minister of agriculture before the nation's civil war. He narrowly defeated former President George M. Weah during the November 2023 runoff election.
From January 2006 to January 2018, Boakai served as Vice President in the administration of then President Ellen Johnson Sirleaf, a government that attracted millions of United States dollars to revamp the agricultural sector.
Though the sector is gradually transforming, the Boakai administration is expected to provide adequate support for the sector and to ensure policy enhancement in order to stimulate agricultural growth.

Improving Optimization Performance Using Parallel Computing
This example shows how to improve optimization performance using the Parallel Computing Toolbox™. The example discusses the speedup seen when using parallel computing to optimize a complex Simulink® model. The example also shows the effect of the number of parameters and the model simulation time when using parallel computing.
Requires Parallel Computing Toolbox™
- An Example Illustrating Optimization Speedup
- When Will an Optimization Benefit from Parallel Computing?
- Number of Parameters and Their Effect on Parallel Computing
- Gradient Descent Method and Parallel Computing
- Pattern Search Method and Parallel Computing
- Overhead of Distributing an Optimization
- Uncertain Parameters and Their Effect on Parallel Optimization
An Example Illustrating Optimization Speedup
The main computational load when using Simulink Design Optimization is the simulation of a model. The optimization methods typically require numerous simulations per optimization iteration. As many of the simulations are independent, it is beneficial to use parallel computing to distribute these independent simulations across different processors.
Consider the Simulink model of a HL20 aircraft, which ships with the Aerospace Blockset™. The HL20 model is a complex model and includes mechanical, electrical, avionics, and environmental components. A typical simulation of the HL20 model takes around 60 seconds.
During landing, the aircraft is subjected to two wind gusts from different directions which cause the aircraft to deviate from the nominal trajectory on the runway. Simulink Design Optimization is used to tune the 3 parameters of the controller so that the lateral deviation of the aircraft from a nominal trajectory in the presence of wind gusts is kept within five meters.
The optimization is performed both with and without using parallel computing on dual-core 64bit AMD®, 2.4GHz, 3.4GB Linux® and quad-core 64bit AMD, 2.5GHz, 7.4GB Linux machines. The speed up observed for this problem is shown below.
The HL20 example illustrates the potential speedup when using parallel computing. The next sections discuss the speedup expected for other optimization problems.
When Will an Optimization Benefit from Parallel Computing?
The previous section shows that distributing the simulations during an optimization can reduce the total optimization time. This section quantifies the expected speedup.
In general, the following factors could indicate that parallel computing would result in faster optimization:
- There are a large number of parameters being optimized
- A pattern search method is being used
- A complex Simulink model that takes a long time to simulate
- There are a number of uncertain parameters in the model
Each of these is examined in the following sections.
Number of Parameters and Their Effect on Parallel Computing
The number of simulations performed by an optimization method is closely coupled with the number of parameters.
Gradient Descent Method and Parallel Computing
Consider the simulations required by a gradient-based optimization method at each iteration:
- A simulation for the current solution point
- Simulations to compute the gradient of the objective with respect to the optimized parameters
- Once a gradient is computed, simulations to evaluate the objective along the direction of the gradient (the so called line search evaluations)
Of these simulations, the simulations required to compute gradients are independent and are distributed. Let us look at this more closely:
Np = 1:16; %Number of parameters (16 = 4 filtered PID controllers) Nls = 1; %Number of line search simulations, assume 1 for now Nss = 1; %Total number of serial simulations, start with nominal only
The gradients are computed using central differences. There are 2 simulations per parameter, and include the line search simulations to give the total number of simulations per iteration:
Nss = 1+Np*2+Nls;
As mentioned above the computation of gradients with respect to each parameter can be distributed or run in parallel. This reduces the total number of simulations that run in series when using parallel computing as follows:
Nw = 4; %Number of parallel processors Nps = 1 + ceil(Np/Nw)*2+Nls;
The ratio Nss/Nps gives us the speedup which we plot below
Nls = 0:5; %Vary the number of line search simulations figure; hAx = gca; xlim([min(Np) max(Np)]); for ct = 1:numel(Nls) Rf = (1+Nls(ct)+Np*2)./(1+Nls(ct)+ceil(Np/Nw)*2); hLine = line('parent',hAx,'xdata',Np,'ydata',Rf); if ct == 1 hLine.LineStyle = '-'; hLine.Color = [0 0 1]; hLine.LineWidth = 1; else hLine.LineStyle = '-.'; hLine.Color = [0.6 0.6 1]; hLine.LineWidth = 1; end end grid on title('Gradient descent based relative speedup') xlabel('Number of parameters') ylabel('Serial time/parallel time') annotation('arrow',[0.55.55],[5/6 2/6]) text(8.5,1.75,'Increasing number of line searches')
The plot shows that the relative speedup gets better as more parameters are added. The upper solid line is the best possible speedup with no line search simulations while the lighter dotted curves increase the number of line search simulations.
The plot also shows local maxima at 4,8,12,16 parameters which corresponds to cases where the parameter gradient calculations can be distributed evenly between the parallel processors. Recall that for the HL20 aircraft problem, which has 3 parameters, the quad core processor speedup observed was 2.14 which matches well with this plot.
Pattern Search Method and Parallel Computing
Pattern search optimization method is inherently suited to a parallel implementation. This is because at each iteration one or two sets of candidate solutions are available. The algorithm evaluates all these candidate solutions and then generates a new candidate solution for the next iteration. Evaluating the candidate solutions can be done in parallel as they are independent. Let us look at this more closely:
Pattern search uses two candidate solution sets, the search set and the poll set. The number of elements in these sets is proportional to the number of optimized parameters
Nsearch = 15*Np; %Default number of elements in the solution set Npoll = 2*Np; %Number of elements in the poll set with a 2N poll method
The total number of simulations per iteration is the sum of the number of candidate solutions in the search and poll sets. When distributing the candidate solution sets the simulations are distributed evenly between the parallel processors. The number of simulations that run in series after distribution thus reduces to:
Nps = ceil(Nsearch/Nw)+ceil(Npoll/Nw);
When evaluating the candidate solutions without using parallel computing, the iteration is terminated as soon as a candidate solution that is better than the current solution is found. Without additional information, the best bet is that about half the candidate solutions will be evaluated. The number of serial simulations is thus:
Nss = 0.5*(Nsearch+Npoll);
Also note that the search set is only used in the first couple of optimization iterations, after which only the poll set is used. In both cases the ratio Nss/Nps gives us the speedup which we plot below.
figure; hAx = gca; xlim([min(Np) max(Np)]); Rp1 = (Nss)./( Nps ); Rp2 = (Npoll)./( ceil(Npoll/Nw) ); line('parent',hAx,'xdata',Np,'ydata',Rp1,'color',[0 0 1]); line('parent',hAx,'xdata',Np,'ydata',Rp2,'color',[0.6 0.6 1]); grid on title('Pattern search based relative speedup') xlabel('Number of parameters') ylabel('Serial time/ parallel time') legend('Search and poll sets','Poll set only')
The dark curve is the speedup when the solution and poll sets are evaluated and the lighter lower curve the speedup when only the poll set is evaluated. The expected speedup over an optimization should lie between the two curves. Notice that even with only one parameter, a pattern search method benefits from distribution. Also recall that for the HL20 aircraft problem, which has 3 parameters, the quad core speedup observed was 2.81 which matches well with this plot.
Overhead of Distributing an Optimization
In the previous sections, the overhead associated with performing the optimization in parallel was ignored. Including this overhead gives an indication of the complexity of a simulation that will benefit from distributed optimization.
The overhead associated with running an optimization in parallel primarily results from two sources:
- opening the parallel pool
- loading the Simulink model and performing an update diagram on the model
There is also some overhead associated with transferring data to and from the remote processors. Simulink Design Optimization relies on shared paths to provide remote processors access to models and the returned data is limited to objective and constraint violation values. Therefore, this overhead is typically much smaller than opening the MATLAB® pool and loading the model. This was true for the HL20 aircraft optimization but may not be true in all cases. However, the analysis shown below can be extended to cover additional overhead.
findOverhead = false; % Set true to compute overhead for your system. if findOverhead % Compute overhead. wState = warning('off','MATLAB:dispatcher:pathWarning'); t0 = clock; parpool %Open the parallel pool load_system('airframe_demo') %Open a model set_param('airframe_demo','SimulationCommand','update') %Run an update diagram for the model Toverhead = etime(clock

This paper designed and optimized a bidirectional three-port valve plate structure for solving the matching problem of flow rate and pressure in the aerospace pump-controlled differential hydraulic cylinder. This design aims to make the valve plate work well under the bidirectional high-speed condition. The model was set up using dynamic mesh and sliding mesh, and the simulation is conducted by FLUENT. In addition, the flow field of inlet and outlet flow rate pulsations, pressure pulsation in cylinder, and non-dead-point transition zone of four cases are analyzed to optimize the valve plate in this work. The numerical results show that different angles of non-dead-point transition zones of the valve plate have a big impact on the performance of the piston pump. For example, the flow rate pulsation reaches the minimum when the angle of non-dead point transition zone is greater than or equal to the angle of a cylinder port. However, at this time, the closed compression would occur and the pressure inside the cylinder would rise rapidly as the piston moves to the non-dead point zone, thus resulting in serious pressure overshoot. In addition, if the angle of non-dead point transition zone is reduced within a certain range, the pressure overshoot will be reduced drastically, and the flow pulsation rate will rise a bit. The study suggests that it is necessary to adjust the angle of non-dead point transition zone to balance the pressure overshoot and flow pulsation of the pump to obtain the optimal kidney structure of the valve plate.

An Advanced Engine Drivetrain Control System 970291
A concept for a new engine drivetrain control system that can attain improved exhaust emissions and fuel economy was investigated. The system integrates direct-injection stratified engines with high-pressure charge, a sophisticated continuously variable transmission, and hybrid systems such as electric motor drives. The system is composed of two three-cylinder engines, which are used singly or in combination according to the circumstances. During a traffic jam, the vehicle is driven by the electric motor, at partial load, it is driven by three cylinders, and at full load, by six cylinders with brake energy stored in a battery. The battery is charged at partial and full loads. The system has an expert subsystem that controls the charge and discharge of the battery according to driving data from a car navigation system. Some simulation results of fuel economy gain and exhaust emissions were evaluated using optimum control strategies.
