Abandoned mineshafts could be used to heat Glasgow
by James Morgan
15 February 2013
In certain cases, it will be necessary to dig up streets in order to install new pipes and cables. I think that working out how to do this will prove to be the biggest challenge. However, a lot of our work is likely to be carried out in conjunction with new developments in which a centralised heat-pumping system will distribute water around houses and offices.
Experts from Glasgow Caledonian University (GCU) believe that disused coal mines could help to solve the problem of fuel poverty within Scotland's largest city. The researchers, whose work is being partly funded by ScottishPower Ltd, suspect that the warm water contained within Glasgow's abandoned mineshafts can be used to heat roads, pavements and homes.
This might sound too good to be true, but Glasgow wouldn't be the first city in the world to adopt such an approach. Hamburgers and Stockholmers already enjoy similar systems that take advantage of the geothermal energy beneath their feet. If the team – led by Project Director Dr Nick Hytiris, Senior Lecturer at GCU's School of Engineering and Built Environment – concludes that Glasgow is a suitable candidate for such a system, it has been calculated that the subterranean water supply could provide heating for approximately 40 per cent of the city's population.
To find out more about the benefits that might result from this network of almost-forgotten mineshafts, I spoke to GCU's Bjørn Aaen, a participating researcher and former technical advisor to Glasgow City Council. I began by asking how he and his colleagues plan to identify reservoirs with the potential to fuel this under-street heating system.
"We will begin by studying the maps that have already been developed by Glasgow City Council and the British Geological Survey (BGS)," Aaen replied. "These 3D models are really detailed representations of subterranean Glasgow, and they show that there are reservoirs of water stored within the city's old mine workings. The trick will be to identify the best reservoirs to use. Utilising very shallow mine workings, for instance, could cause problems relating to instability. Having said that, any water that we draw from reservoirs will be pumped back again, so there should be very little overall change in volume.
"Even so, it might be more sensible to choose reservoirs that exist at a depth of about 50m or so," he continued. "At these levels, the temperature doesn't tend to vary with the seasons. You don't have to go very deep into the ground to find water with a temperature that remains stable all year round."
Of course, assuming that Aaen and his colleagues do find a sufficient number of reservoirs to make this project economically viable, it still remains for them to pump the warm water to the places in which it is needed. I asked how difficult it would be to integrate such a system within Glasgow's already bustling underground infrastructure.
"To some extent, this depends on the distance that the water has to travel," Aaen explained. "In certain cases, it will be necessary to dig up streets in order to install new pipes and cables. I think that working out how to do this will prove to be the biggest challenge. However, a lot of our work is likely to be carried out in conjunction with new developments in which a centralised heat-pumping system will distribute water around houses and offices. For example, we are going to be working in the Clyde Gateway Regeneration area; the largest regeneration area in Scotland. As we will be starting from scratch, installing geothermal heating systems will cause very little disruption. Naturally, we will do our best to avoid digging anything up without good reason."
In the United Kingdom, a household is said to be in fuel poverty if – in addition to meeting the costs of utilities such as lighting, appliances, cooking and water heating – it spends more than 10 per cent of its income on maintaining a satisfactory heating regime.1 During recent years, energy prices have risen at a faster rate than the average income in Glasgow, leading to higher levels of fuel poverty across the city. Indeed, according to the 2008 Scottish House Condition Survey, 25 per cent of Glaswegian households are 'fuel poor'.2
In light of such statistics, I asked Aaen about the extent to which this initiative will provide heating for domestic purposes? How many people could benefit from Glasgow's geothermal energy resource?
"It has been calculated that during a 100-year period, up to 40 per cent of Glasgow's heating needs could be met by this energy resource," he replied. "It has the potential to make fuel costs more affordable for huge numbers of people. Moreover, there is existing evidence to this effect. The residents of Glenalmond Street have had this system installed for over a decade now. Whilst I am only talking about 17 houses – it is quite a small setup – the residents have reported that their heating bills have dropped to approximately £150 per year. Heating homes in this way is much cheaper than using gas or electricity."
Finally, I asked Aaen whether other UK cities are likely to follow suit if he and his colleagues find Glasgow to be a suitable host for this expansive geothermal heating infrastructure. As he explained, locations across the home nations could take advantage of their mining heritages.
"There are numerous towns and cities that exist above old mine workings similar to those that can be found beneath Glasgow," Aaen concluded. "Places across Central Scotland, England and Wales could certainly benefit from the same type of technology. After all, the remnants of mining past are spread widely across the UK and beyond."

Animal Species:Golden-spined Ant
Golden-spined or Golden Ants have a metallic sheen to their body, which is covered in golden hairs.
Golden-spined Ants have a strangely spined thorax, probably used in defence against predators.
8 mm - 11 mm
Golden-spined Ants are found throughout Australia.
Found in urban areas, forests and woodlands, heath, Golden-spined Ants often nest in sand at the base of shrubs and trees.
Many Golden-spined Ants stay in their nest during wet or extremely hot periods.
Feeding and Diet
Golden-spined Ants are omnivores. They collect nectar and pollen from a wide range of plants including eucalypts and acacias. They also collect dew from these plants early in the morning. They forage as individuals and can be seen on food-collecting missions at most times and in most weather conditions.

TORONTO -- With warm weather approaching and the promise of a "one-dose summer" on the horizon, many Canadians are making plans for the summer and fall, eager for life to get back to pre-pandemic "normal." But not all Canadians are happy to see the end of lockdown life brought about by COVID-19 restrictions.
The term 'cave syndrome' has been bandied about in news headlines and on social media, a term being used to describe people who may not be so willing to resume normal life when the COVID-19 pandemic sees its end. But while it may accurately describe people's genuine struggle to return to normal lives as restrictions ease, psychologists say it's a term that oversimplifies and pathologizes things.
"It's not a syndrome because there could be any number of reasons why people are choosing to stay at home," Steven Taylor, clinical psychologist at the University of British Columbia, told in a phone interview.
This term is gaining popularity before the pandemic has even ended, and it's still too soon to tell how much we'll continue to be affected once the crisis is over.
"At this point it is really hard to assess or understand how severe these issues are because the whole thing is still ongoing," he said. "So someone could be fairly anxious right now about leaving the home, but once the pandemic is over, that person might be fine."
And at this stage in the pandemic, there is no clear ending. What might be the end for one person, won't be the end for another.
"The end of the pandemic is going to be different for everybody. In all likelihood the pandemic is going to evolve into an endemic," Gordon Asmundson, clinical psychologist and professor of psychology at the University of Regina, told in a phone interview.
He said that the term 'cave syndrome' is too broad and encompasses any reason someone might have for not leaving their home, including finding it more convenient to work from home, or cheaper to do online post-secondary schooling.
"Some of those reasons may be adaptive reasons, so they're not really symptomatic of anything," he added.
With a term that includes so many reasons for not wanting to leave the house, or ease COVID-19 restrictions, it could overlook more serious diagnoses at play.
"A key consideration is whether leaving the cave is an inconvenience or an emotional burden, and almost insurmountable challenge, and in the latter case, there might be other diagnoses that are more specific and helpful," said Asmundson.
It could prevent people from realizing their issues with leaving the house are more severe than general convenience and enjoying alone time. It could mean missing that someone is staying home because of depression or a panic disorder.
"If you call this a syndrome, then the problem is that you might have missed some of the other disorders," said Taylor.
And there's no need to give a diagnosis to something that creates a feeling of inconvenience more than anything else.
"If it's an inconvenience, but doesn't really affect your functional ability, then those things shouldn't be pathologized," said Asmundson.
It also over emphasizes the mental health issues that psychologists expect to see after the pandemic comes to an end. Early on in the pandemic, Taylor and Asmundson worked together on the impacts of what they call COVID Stress Syndrome, a term used to describe the overwhelming and life-disrupting fear of infection and the consequences of a COVID-19 infection.
"It can over pathologize ordinary anxiety and it's ordinary and normal and expected to be anxious during COVID-19," said Taylor.
He doesn't believe the general stress of the pandemic will have staying power for most people.
"Most people will pick up where they left off and bounce back, but not everyone," said Taylor. "This is a big issue at the moment, trying to estimate the proportion of people who will come through this stressful event and will need psychological help and it's really hard to predict."
This isn't to say that the pandemic hasn't had negative effects on mental health for Canadians.
"The pandemic is having a greater impact on people who have these pre-existing conditions. And then in some people it's creating new conditions, like post traumatic stress disorder, particularly in frontline workers," said Asmundson.
And part of the challenge now is that for most of the pandemic, people with anxiety and panic disorders have been able to stay home and avoid the things that might cause them anxiety, which could actually worsen things.
"Avoidance is one of the key fuels to the fire of anxiety and stress," he said. "It's a really effective coping strategy in the short term, you avoid what stresses you out, you feel better, but in the long term the avoidance comes at a cost and you start missing out on opportunities to learn that you often overestimate the amount of threat that's out there."
Paying attention to how you feel after restrictions have lifted will be very important for those who might be feeling more anxious than usual. If restrictions have lifted but you still fear a trip to the grocery store, it may be something more serious.
"Once the restrictions have lifted and it's gone weeks or months and you're still inside and you're still very frightened, that might be an indication that you might need some help, particularly if the anxiety is interfering with your life," said Taylor.
If you find yourself overwhelmed in the weeks and months after the COVID-19 pandemic comes to an end, or at least when restrictions are lifted, there are free resources available online that Asmundson says are just as good as in-person therapy.
"One of them is called Mind Shift through Anxiety Canada, is freely available and it's an evidence-based online app that people can actually log into and it's like your own personal therapist on the phone, except it's not a person, it's a program," he said.
While 'cave syndrome; might be a catchy name, it doesn't do justice to the reasons people may not want to leave the house, and tries to diagnose people who don't want to return to a pre-pandemic "normal."
"It really overlooks the diversity and reasons why people don't want to go out. It seems to psycho-pathologize all of us who don't want to return to exactly the way things were before."

Should there be mandatory national service?
Multiple countries around the world require mandatory national service for citizens who are of a certain age, gender, and health. This institution has been highly controversial in recent decades, due to the rise of democracy and creation of paid and voluntary standing militaries.
No, mandatory service should not exist
Mandatory service should not exist because it is an infringement on individual rights and freedoms. Mandatory service forces people to serve in conditions that have a high risk for danger and death.
Mandatory service requirements infringe on civil rights
Mandatory national service is a violation of civil and individual rights. Mandatory national service forces citizens into harmful and dangerous situations against their will, with little to no benefit.
Mandatory service requirements are easily manipulated
Mandatory national service requirements can easily be manipulated by the wealthy to avoid conscription and service. This would make mandatory service requirements affect certain populations disproportionally.
Yes, mandatory service is essential
Mandatory service is essential to keep a nation's economy, safety, and political system thriving. Citizens should give back to their nation by serving to keep it safe.
Mandatory service keeps the country safe
Mandatory national service ensures there is never a shortage of people to keep the nation safe. Mandatory service requirements maintain stability in the safety of the nation.
Mandatory service promotes patriotism and unity
Mandatory service provides a sense of patriotism and duty for citizens. An increased level of pride from an individual to their nation leads to a healthier population.
Mandatory service can save governments money
Mandatory service can save governments money on ads and commercials to promote volunteer service. Mandatory national service also helps keep the economy stable because people who serve their nation are more likely to keep steady jobs and give back to the nation.

THE ZENITH EFFECT: A CASE STUDY
Published on 22nd October 2022
The nature of asset inspection is that each presents individual challenges. Many solutions have been promised over recent years, yet most haven't lived up to the hype. However, today's technology brings a whole different level to NDT testing, such as that proven by Interactive Ariel's innovative inspection camera, Zenith.
The following looks at a typical example of how this vertical space inspection instrument can overcome many of the historical issues associated with closed space and/or working at height inspection.
The asset in question was a 22 ft (6.7 m) sphere tank used to store vinyl fluoride. Legislation demanded regular inspections of the tank, something that had previously been actioned by the erection of interior complex scaffolding. Once done, inspectors carried out the work, manually inspecting the walls of the tank for any cracks, damage or deterioration. This took up to two days, after which the scaffolding needed to be removed.
The total time to carry out the process took four days, something that site owners, DuPont, were keen to reduce. They also wanted to remove the need for dangerous human entry to a confined space and the need for scaffolding.
Interactive Ariel was keen to show how Zenith could overcome all of the traditional challenges. The inspection camera has been designed for just such a task, using a combination of advanced systems to allow fast, safe operation that returned superior inspection data.
Zenith consists of a stabilised camera that's lowered from a multi-configuration tripod into a vertical space. The construction of the tripod is such that even entry points that are offset to where the camera is set up are easy to overcome, something that was necessary for this particular task. The camera can capture 4k video, 18Mp images and has a 30x optical zoom. This is further complemented by integral lighting of 10,000 lumens, enough for even the darkest of areas.
The camera was lowered into the asset using its battery-powered Smart Winch system, meaning no manual operation is needed during the inspection. Working with an intuitive handheld controller, the inspector can stand up to 900 metres away and watch real-time images on an HD screen. The camera can be rotated around 360o, focusing on any required area. The advanced operation of Zenith allowed the inspector to capture images with the same zoom level and frame overlap accuracy, even though the camera was at varying distances from the walls, due to the asset's spherical shape.
The results were exactly what DuPont had hoped for, and included:
- A reduction of asset downtime from four days to only 30 minutes (for the actual inspection to take place)
- 100% inspection coverage of the tank's interior
- No need to break the plane for confined space entry
- A dramatic reduction in inspection costs – saving three days downtime and $25,000 (US dollars) in scaffolding costs
This is just one example of how effective Zenith can be for vertical inspections. In addition, the system is simple to use and can be operated by anyone, with no need for prior training.
Advanced robotic solutions are certainly the way forward for what are now antiquated inspection processes. Companies that are embracing such methods are reaping the benefits. In a world where industry competitiveness is more complex than ever, the reduction of time and cost of inspection tasks is essential. Never has the time been so right to discover how to overcome your business challenges. Zenith is but one solution. Are you aware of what else is out there?

text: Thailand's flood crisis in 2011 brought damage to many areas in Thailand. Especially in Bangkok, the water could not drain into the Gulf of Thailand at that time. This paper aims to apply two algorithms, consisting of the generic augmenting path algorithm and the labelling algorithm, in order to determine the maximum flow of water from the north of Bangkok to the Gulf of Thailand. The flow of water in Bangkok is represented by network flow. Rivers and canals are represented by nodes and arcs. Labelling and the generic augmenting path algorithms were used to find the water route from a source to a sink and maximum water flow respectively. The results showed that the maximum flow in Bangkok was 228,960,000 cubic meters per day.

The Foster City Public Works Department this week began raising the water level of the Foster City lagoon by six to eight inches to prepare for summer.
The lagoon's levels are typically lowered in winter in case seasonal storms bring additional water. Levels are raised in the summer to accommodate recreational activities like sailing and windsurfing while making it harder for algae or other plants to grow.
Rainfall can raise the lagoon's water levels or the Public Works Department can let water into the lagoon at high tide. The water level will be higher on weekends and holidays and lower in the middle of the week to promote maximum water exchange in the lagoon.
The city's Lagoon Management Plan sets standards for these water levels. If major rainfall is forecast at any time of the year, the water level will be lowered once more to accommodate runoff and prevent flooding.
The lagoon, approximately 212 acres in size, acts as a drainage detention basin for the city, as storm water from the city flows into the lagoon and is pumped into the Bay. The lagoon can withstand a major storm likely to occur once a century.


cans of food dangling in your backpack can make a lot of noise. When rushing out, all the items you carry with you can make some noise, so you need to pack light.
Suggested article: Scavenging and Salvaging Supplies Post Collapse
You have to consider light clothing and proper footwear if you travel when SHTF. In the city, you need to move quickly and you have to be as quiet as possible. Clothing that prevents movement or shoes that make noise should be avoided.
Noise, shadowing and silhouetting are your most common enemies in the city. If you travel when SHTF, you must pay attention to these three factors. It is essential as they will give away your position in no time. In the city, there are a lot of corners. Your shadow may extend around the edge of a building and draw attention.
There can be a lot of light sources from fires or other improvised means (lanterns, flashlight, etc.). This means that others will be able to see your silhouette against the light if you don't pay attention to your surroundings. Not to mention that there will be a lot of trash and you have to watch your step if you travel when SHTF. You can injure yourself, or you can make noise that will alert others.
Travel when SHTF – Reminder List:
 1. You should always know your route, regardless if it's an in or out route. Even more, you should have alternative ways if you travel when SHTF.
 2. Nighttime is more indicated if you have to travel when SHTF.
 3. If you travel when SHTF you should avoid as much population as possible. You should stay away from highways and exits.
 4. You need to have different means of travel when SHTF.
 5. If you travel when SHTF you should avoid using fire. You shouldn't make noise and you should always be on guard.
 6. Having the ability to stay hidden and to see in the dark will give you the upper hand if you travel when SHTF.
 7. Proper clothing and footwear are a must if you have to travel when SHTF. You will need movement liberty while at the same time you shouldn't make any noise.
 8. Plan your supplies to last. You should know in advance what you need to leave behind if you travel when SHTF.

2 thoughts on "Suggestions On How To Travel When SHTF"
 1. Nice article. Many good points.
 Our plan involves taking both our trucks at a minimum, along with a travel trailer. Losing one allows us to continue with the other, with reduced capacity, of course.
 What a lot of preppers fail to consider is that some scenarios are un-survivable. Loss of transportation in an area of unrest is a huge blow. Motorized cycles are certainly better than foot for speed, but they rely on the same roads as regular BOVs, and have absolutely no sheet metal cover to potentially deflect projectiles.
 Transit through troubled areas might best be viewed as a military problem. How best to move in an escape and evade mode. Because, that's pretty much what it is.
 Leave early. If you're caught in the muck, you're just about dead.
 2. It's good to think about and to have a plan, but it depends on where you live and other factors including unfortunately..Luck..Even the best laid plans can blow up in your face..

Best answer
It can be observed that radius (r) of the cylindrical part and the hemispherical part is the same (i.e., 7 cm).
Height of hemispherical part = Radius = 7 cm
Height of cylindrical part (h) = 13 −7 = 6 cm
Inner surface area of the vessel = CSA of cylindrical part + CSA of hemispherical part
= 2 πrh + 2π r2
Inner surface area of vessel
= 2 x 22/7 x 7 x 6 +2 x 22/7 x 7
= 44(6+7)
= 44 x 13
= 572 cm2

To make an educated decision, you need to know what publishing does and what it does not.
Publishing is the process of copying content from one database to another. By default there is one source database -
master and one destination database
web database is the publishing target.
When you publish, Sitecore copies data from 3 tables
UnversionedField. Copy here is not just moving bytes. It is a sophisticated process that transforms data to the form that works best for delivery. From top of my head the following transformations are performed:
- Clones are merged
- Language fallback fields are materialized
- Old Item versions are removed so only recent one is kept
But Sitecore is not just
Fields. Other important artifacts are not moved when you publish content. What is not included:
- xDB data
- Sitecore modules, fixes, updates
- Users and Roles (although permissions are moved as they are stored in Item
- Application Files - configuration, CSS, JS, Razor views and others
- Application Code
After content is copied, target Server receives
publish:end:remote event. During this event pipeline Sitecore clears caches for affected items and pushes affected items to Search Indexes.
As you can see, publishing is an expensive process. It may be an overkill to use it if you want to have two always synchronized environments. Consider shared database or SQL Replication for that scenario.
Multiple Publishing Targets work best for scenarios when two conditions are met:
- Sitecore and your App versions are synchronized
- You need to control over how your content is traveling from one environment to another.

Pataky Name History
The Hungarian Language is quite distinct from its Germanic and Slavonic neighbors, and is of Finno-Ugric rather than Indo-European origin. Thus, it is related to Finnish. Nevertheless, the strongest cultural influence in historical times has been German, and the pattern of Hungarian surnames is similar to that found in Germany and Austria. Hungarian surnames are placed before rather than after the given name. A few surnames that are relatively common in Hungary are not in fact of Hungarian linguistic origin; they represent Magyarized forms of German and Slavonic names imported from neighboring regions.
The Hungarian surname Pataky is of locative origin. Locative surnames are those names which derive their origin from a particular feature, either man made or natural, near which derive the original bearer lived or held land. In this instance, the surname Pataky is derived from the Polish word "potok", meaning "stream". Thus, the surname Pataky was the name given to someone who lived by a brook or stream. Pataky is the Hungarian form of the name. Variants of this surname include such names as Patak, Pataki, Potok, Potocki, and Potucek.
References to this surname or to a variant include a record of the Pataky family who were a very large and noble family of Hungary. A specific blazon of arms was granted to one Johann Pataky in 1703.

text: Experimental, analytical, and archaeological evidence is presented to describe the characteristics of thermal alteration in mesolithic assemblages from the northern Netherlands. Experiments, both in the field and in the laboratory, have established the sequence of changes that occur when flint is subjected to heat. Analytical techniques involving the scanning electron microscope and thermoluminescence analysis are used in an attempt to recognize thermal pretreatment and to define the stages in manufacturing in which it was used. The proportions and spatial distributions of thermally-altered artefacts are employed to compare archaeological assemblages and to locate heat sources on occupation floors. In spite of high incidence of heat alteration in the assemblages, there is no conclusive evidence for intentional thermal pretreatment.


Community cohesion, inclusion and equality
Greater community cohesion, inclusion and equality enhance local democracies and help to lay the foundations in which local areas can flourish.
Councils have role to play in building cohesive communities, which are places that:
 - Offer a common vision and a sense of belonging for all;
 - Positively value diversity;
 - Provide equal opportunities to people from different backgrounds; and
 - Provide an environment where strong and positive relationships can be developed between people from different backgrounds in the workplace, in schools and within neighbourhoods.
Promotion of equality is integral to building community cohesion. Local cohesion may be undermined where some groups have different experiences or outcomes to others, especially where linked to a group's protected characteristics (though difference of opportunity may not necessarily be related to protected characteristics alone).
Councils have a role in helping to tackle inequalities and related issues, such as fostering good relations across and between communities and supporting efforts to prevent extremism and tackle hate crime, including against those with protected characteristics.
This page provides resources to support councils in building more equal, inclusive and cohesive communities.

barking dog, Bucharest (not realized)
For no other creature is territorial behavior so pronounced as it is for dogs. It is based on the instinct to take possession of a territory, to mark it and to defend it. Directly in front of the Palace of the Parliament in Bucharest the leashed or enclosed animal would be an appellative symbol of a lost terrain, of the seizure and appropriation of public space for dictatorial and propaganda purposes by the then president Nicolae Ceausescu. In the process of constructing the palace in 1984, which included extensive plazas and boulevards, around 40,000 homes and countless churches and synagogues were torn down, and evictions were carried out in parts of the old city in the 1970s. The site of the former "People's House" would be temporarily occupied by the visibly "domesticated" dog, who thus symbolically reclaims the environment and living space of the citizens. (JO)

In order to assess the current situation, the main library at 355 Schoenbeck Rd., Wheeling, completed engineering studies on the building in 2010 and 2013 and community focus groups in 2012. These studies determined there were several mechanical and building issues that needed to be resolved for the building to operate as cost-efficiently as possible. For example, we currently have an all electric building that is very inefficient for heating and cooling the facility.
The library also lacks sufficient meeting and classroom space to serve our members' needs. The current building is 46,000 square feet, which is inadequate to serve our population of 67,000. Almost 15,000 square feet will be added to the building.


Mismatch between wages and cost of living
By : Sofea Azahar
The mismatch between wages and cost of living has been a longstanding issue and it surely has no one-size-fits-all solution but we need to start somewhere at some…
Amid the challenging economic condition originated from the pandemic, many people have also been struggling to cope with cost of living which do not appear to be in the same trend with the incomes of many Malaysians as they have been severely affected due to cost-cutting measures by their employers. Therefore, this calls for a compatible and sustainable solutions.
Although inflation is trending at low levels, cost of living is said to extend beyond prices. According to the World Bank's study, the issues pertaining to cost of living include stagnant growth in incomes, elevated household debt as well as unaffordable housing.
Based on the statistics from the Department of Statistics (DOSM), mean household income at the national level grew by 4.3 per cent in the period between 2016 and 2019 whilst mean disposable income (income after current transfer deductions) went up by 4.5 per cent in the same period.
Across income groups, mean household incomes for the B40, M40 and T20 also grew throughout the same period.
But the question is, are the latest statistics reflective of the current reality, especially after the unprecedented occurrence of the pandemic?
Mean household expenditure increased by 4 per cent during the 2016-2019 period. Among all expenses, food and beverages accounts for the biggest portion at 17.3 per cent and within the income groups, B40 households allocate high share of their expenditure on food compared to those in other income groups.
But this also comes with the fact that food prices are on an increasing trend compared to other CPI items. Given that the low-income households tend to spend more on food, should food prices continue to accelerate quicker than other items, these households would certainly feel the pinch from higher inflation rate.
Additionally, household debt is at a high level — 82.7 per cent of GDP in 2019. Financial literacy amongst Malaysians is also poor, particularly among youths. Not only we have increased unemployment due to Covid-19, there is also an issue of underemployment.
When discussing about cost of living, the status of poverty should also be considered because the poor household group is the most unfortunate amongst all.
Poverty is measured using the poverty line income (PLI) whereby the concept and methodology is based on the minimum requirement of nutritional food and non-food items (clothing, housing, transportation and others) required by each household to live an active and a healthy life.
In 2019, the national PLI was revised higher from RM908 in 2016 (based on previous methodology) to RM2,208. As a result, the absolute poverty rate has jumped from 0.4 per cent in 2016 to 5.6 per cent in 2019.
But concern pertaining to this matter arise because the current PLI has not taken into account of the Covid-19 pandemic which have affected socioeconomic well-being of many.
Since then, more people have lost their jobs, have had to undertake pay-cuts or have been put on unpaid leave. Given the challenging circumstances, households might have to resort to earning side incomes or search for any possible means to make ends meet, i.e. join the informal sector.
According to the Minister in the Prime Minister's Department (Economy) Datuk Seri Mustapa Mohamed, based on the estimates by DOSM after taking into account of the pandemic, poverty rate could be lifted by 3 per cent points from the current official 5.6 per cent.
So, we could see more than the previously-reported 405,441 households living in poverty because of the heavy blow from the crisis.
Cost of living, purchasing power and the income level of households to purchase food and non-food items at minimal level (PLI) also vary across states. The general perception is that the cost of living in the urbanised states are more expensive than the less developed states. But for some states, such might not be the case.
If we were to look at the PLI by state, Sabah and Labuan topped other states including developed ones like KL and Selangor with their high PLIs — RM2,537 and RM2,633 respectively. Poverty rate in Sabah was also the highest at 19.5 per cent.
This shows that it is also costly living in East Malaysia, not only in the big cities.
Wage gap between states is also not helpful in supporting the cost of living. An example can be taken from EMIR Research's focus group discussion in 3Q20 whereby a discussant from Sabah mentioned that there is a need to standardise salaries across the country given that the cost of living in Sabah is as high as in the urbanised cities but the salary gap is very huge!
These are the ground realities which might not be completely represented by several official statistics but they can be substantially felt by being on the ground.
Current minimum wages remain low ranging at RM1,100-RM1,200 despite the effort to remove the disparity in wages between Peninsular and East Malaysia.
Let's say a 1-person household earns RM1,200 per month and lives in Kuala Lumpur but the minimum amount of income to acquire basic necessities at minimal level is RM2,216, how would this individual live comfortably given the huge gap?
Even data has shown that labour share of income in Malaysia is much lower than some advanced economies such as Singapore and Korea. This is likely to be evident in sectors that are labour-intensive, sluggish in technological progress and dependent on low-skilled workers.
Increase in wages should be done alongside the upskilling/reskilling of workers (education) and also create more high-skilled jobs through high-value investments. That way, as skillsets of employees expand and become relevant to the demand required by industries, employees will then be able to demand for higher wages.
The mismatch between wages and cost of living has been a longstanding issue and it surely has no one-size-fits-all solution but shouldn't we start somewhere?

Downtown San Luis Obispo flooded due to main break
Water was cut off to a block of homes after a water main break flooded downtown San Luis Obispo Friday night. The pressure from the water caused pavement and soil to buck underground. Eventually, the mixture forced itself through the concrete, bucking upwards.
To keep other old water mains from breaking, firefighters had to release water from nearby fire hydrants.
According to the San Luis Obispo Tribune, "Watching all that water run down the street during a drought was painful for residents."
The broken pipe was eventually replaced and water was restored the following day.
The iron water main that broke was installed in 1942.

Case Study
Ansys + Apollo Tyres
"Ansys Fluent software helped in analyzing the hydroplaning risk of passenger car tyres by calculating the lift force on the tyres."
— Sowntharya L, Scientist, Tyre Simulation / Apollo Tyres
Hydroplaning occurs when a layer of water builds up between the tires and the road surface, which leads to loss of contact that prevents the vehicle from responding to control inputs, such as steering, braking or accelerating. The tread design and dimensions play an important role in expulsion of water, thus reducing the risk of hydroplaning. Predicting the speed of onset of hydroplaning and the lift force experienced by the tire aids in optimizing the tread pattern.
Hydroplaning in tires is a safety criterion. Hence, there is a need to minimize the loss of contact by modifying the groove design while keeping the development cost low. Experimental testing is highly expensive and limited, which affects the validation of the simulation results. Also, hydroplaning and tire noise are conflicting phenomena, and they should be optimized with proper balance.
Engineering Solution
Computational fluid dynamics (CFD) analysis using Ansys Fluent simulated the water flow through the car tires. The developed simulation methodology predicted the lift force and hydroplaning speed.
The developed methodology helps in:
- Selecting the best tire pattern to minimize hydroplaning.
- Optimizing water flow channel in tires to delay the onset of hydroplaning.
- Increasing the wet grip potential of tires.

Kikiaola Harbor is located along the southwest coast of the island of Kauai between the towns of Kekaha and Waimea. The Federal project modified an existing harbor, which was originally developed by the State of Hawaii in 1959. The project was authorized under Section 101 of the River and Harbor Act of 1968 and it was completed in 2009 at a cost of $18,771,500.
The Federal project consists of a dredged 725-foot-long entrance channel varying in width from 105 to 205 feet to a depth of 11 feet, a dredged 320-foot-long access channel varying in width from 70 to 105 feet to a depth of seven feet, removal of 150 feet of the existing outer east stub breakwater, raising the crest elevation and flattening the seaward slope of approximately 764 feet of the existing east breakwater, removing and reconstructing the 71-foot-long inner east breakwater, and modifying 245 feet of the seaward portion of the existing west breakwater.
These navigation improvements were designed to eliminate dangerous breaking wave conditions within the entrance channel and allow for the safe passage of vessels entering the basin. The local sponsor, State of Hawaii Department of Land and Natural Resources, continues to work towards fulfilling their obligation to construct items of local cooperation such as the sand bypass system and west breakwater root repair. These features are integral to the overall function of the modified harbor project.

Sitework Estimating Florida
Business
Sitework Estimating Florida
Florida is known for its beautiful beaches, warm weather, and vibrant cultures. However, behind the sunny exterior lies a complex world of construction and development. Sitework estimating in Florida is essential to any new building project or infrastructure upgrade.
It involves many factors, including land surveying, earthwork, grading, utility installation, and more. As one of the fastest-growing states in the country with increasing demands for new developments, sitework estimation plays a crucial role in ensuring efficient project planning and budgeting.
I will explore everything you need to know about site work estimating in Florida- from its importance to critical factors to consider when preparing estimates.
Overview of Sitework Estimating in Florida:
In construction cost estimation, Sitework Takeoff plays a pivotal role in the planning and budgeting process for construction projects in the Sunshine State. Estimating sitework involves analyzing and quantifying site-related aspects, including excavation, grading, drainage, utilities, and landscaping. This analysis finds the costs of preparing the construction site.
A Sitework Takeoff Florida lets pros in the state assess the scope of needed site work. They can factor in Florida's terrain and climate. Then, they can make detailed cost estimates. These estimates form the foundation for project management and budgeting. This careful Sitework process ensures that projects are ready to address the unique challenges and opportunities of the state's diverse landscapes and environment. It leads to efficient resource allocation and timely project completion.
Factors Influencing Sitework Estimating Costs in Florida
Factors influencing Sitework estimating costs in Florida can vary depending on the specific characteristics of the construction site and the regional considerations unique to the state. Some key factors that can impact Sitework estimating costs in Florida include:
Site Conditions:
The existing conditions of the construction site, such as soil type, topography, groundwater levels, and environmental considerations, can significantly affect Sitework estimating costs. Sites with challenging terrain or poor soil quality may require extensive earthwork, grading, or foundation work, resulting in higher costs.
Regulatory Compliance:
Florida has specific building codes, zoning regulations, and environmental requirements that construction projects must adhere to. Compliance with these regulations, obtaining necessary permits, and addressing environmental concerns can add to the Sitework estimating costs.
Weather and Climate:
Florida's climate is humid and has frequent rain. It also has the risk of hurricanes. This climate can impact construction schedules and the availability of materials. Sitework estimating costs may need to account for weather-related delays, erosion control measures, and drainage solutions to mitigate the effects of tropical weather conditions.
Utilities and Infrastructure:
Access to utilities like water, electricity, gas, and sewage systems can affect Sitework costs. So can the nearness to existing infrastructure. Extending utilities to the construction site or upgrading existing infrastructure may incur additional expenses.
Labour and Material Costs:
Labour rates, material prices, and worker availability affect Sitework estimating costs. This is true in Florida's construction industry. Cost estimates should include fluctuating labour and material costs due to market demand, supply chain disruptions, or economic conditions.
Accessibility and Transportation:
The location of the construction site can impact Sitework estimating costs. This is due to easy access for equipment and materials, as well as transportation logistics. Remote sites or sites with limited access may require additional resources for transportation, temporary access roads, or logistical planning.
Site Size and Scope:
The size of the construction site, the project's complexity, and the needed site improvements can affect costs. More significant sites, projects with multiple phases, or extensive site development requirements may result in higher costs for Sitework estimation.
Considering these factors and analyzing Sitework in Florida, construction professionals can make accurate cost projections, allocate resources well, and ensure successful project completion.
Strategies for Accurate Sitework Estimating in the Florida Market
To ensure accurate Sitework estimating in the dynamic Florida market, construction professionals can employ several strategies tailored to the region's specific characteristics and challenges. Here are some effective techniques for achieving precision in Sitework estimation in Florida:
Site Visit and Evaluation:
Conduct a thorough site visit to assess the existing conditions, topography, soil quality, drainage issues, and environmental factors that may impact Sitework costs. Gathering firsthand information allows for a more accurate estimation of site preparation requirements.
Utilise Digital Takeoff Tools:
Leverage advanced digital takeoff tools and software to measure quantities, calculate material volumes, and generate detailed estimates for Sitework elements such as earthwork, excavation, grading, utilities, and landscaping. Digital tools streamline the estimating process and reduce errors.
Incorporate Historical Data:
Refer to past projects and historical data from similar Sitework projects in Florida to benchmark costs, analyse trends, and make informed projections based on actual performance data. Historical data can provide valuable insights into cost drivers and variances.
Engage Local Subcontractors and Suppliers:
Collaborate with local subcontractors, suppliers, and vendors with experience in the Florida market. Seek their input on material costs, labour rates, equipment rentals, and logistical considerations to align Sitework estimates with current market conditions.
Consider Regional Factors:
Account for regional factors specific to Florida, such as weather patterns, seasonal variations, environmental regulations, building codes, and utility requirements. Adjust Sitework estimates to accommodate these unique considerations and mitigate potential risks.
Risk Assessment and Contingency Planning:
Conduct a comprehensive risk assessment to identify potential uncertainties, contingencies, and unforeseen circumstances that could impact Sitework costs. Develop contingency plans and allocate reserves to address unexpected challenges during construction.
Regular Communication and Updates:
Maintain open communication channels with project stakeholders, including clients, designers, engineers, and subcontractors, to exchange feedback, clarify requirements, and promptly incorporate changes into Sitework estimates. Regular updates ensure accuracy and alignment with project goals.
Continuous Learning and Improvement:
Stay informed about industry best practices, emerging technologies, and innovative Sitework techniques through ongoing professional development and training. Embrace continuous learning to enhance estimating skills and adapt to evolving market trends.
By implementing these strategies for accurate Sitework estimating in the Florida market, construction professionals can optimise cost projections and deliver successful projects that meet client expectations and regulatory standards.

Phuket Pronunciation: How do you pronounce Phuket?
How to pronounce Phuket or Phucket or Puket or Pooket
Here is an unexpected funny question I get often:
How do you pronounce Phuket?
For most of us, it's obvious, so obvious I'm still surprised when someone asks. I thought 2004 tsunami put Phuket and its name on the map once for all. But not… I still hear lots of hesitation, snickering and giggling. Lately some overseas offices called and asked if my residence was in:
"Fooc..." (hesitates)... "Fuuc... " (errrr...) "Faac...kit"? (giggles).
I couldn't help but giggle back at the embarrassed tone, the poor guy wanted to say the 'F' word so bad...
No sir, you just pronounce 'Poo-ket' [pʰuːkɛt] (in Thai: ภูเก็ต), it's that simple! Just like 'Phi Phi' is pronounced 'Pee Pee' and 'Phang Nga' is 'Pang Nga' (and strangely 'Suvarnabhumi' airport is pronounced "Sue-wanna-poom"!)
Phuket or Phucket or Puket or Pooket, you name it...
So where does 'Phuket' come from? It seems to originate from the Malay 'Bukit' (Book it?) which means 'hill', but was previously named 'Thalang' by locals. Thalang is still the name of the north of the island where the original main town was long ago.
In the 17th century when tin mining made Phuket very attractive to the Occident, Europeans called it 'Jungceylon'. Yes that's the origin of the name given to the giant Jungceylon Shopping Mall in Patong, and looking around the shopping center reveals few hints about old Phuket. If you want to know more about Phuket history, you can visit the Tin Mine Museum in Kathu.
All this story is obviously a lame excuse to post these fun photos showing some of Phuket Streets and buildings in the past and how they look like today :-D

Selection rule for Dirac-like points in two-dimensional dielectric photonic crystals

AbstractWe developed a selection rule for Dirac-like points in two-dimensional dielectric photonic crystals. The rule is derived from a perturbation theory and states that a non-zero, mode-coupling integral between the degenerate Bloch states guarantees a Dirac-like point, regardless of the type of the degeneracy. In fact, the selection rule can also be determined from the symmetry of the Bloch states even without computing the integral. Thus, the existence of Dirac-like points can be quickly and conclusively predicted for various photonic crystals independent of wave polarization, lattice structure, and composition. © 2013 Optical Society of America.

Variable Names
Valid Names
A valid variable name starts with a letter, followed by letters, digits, or underscores. MATLAB® is case sensitive, so A and a are not the same variable. The maximum length of a variable name is the value that the namelengthmax command returns.
You cannot define variables with the same names as MATLAB keywords, such as if or end. For a complete list, run the iskeyword command.
Examples of valid names:Invalid names:
Conflicts with Function Names
Avoid creating variables with the same name as a function (such as i, j, mode, char, size, and path). In general, variable names take precedence over function names. If you create a variable that uses the name of a function, you sometimes get unexpected results.
Check whether a proposed name is already in use with the exist or which function. exist returns 0 if there are no existing variables, functions, or other artifacts with the proposed name. For example:
exist checkname
ans =
If you inadvertently create a variable with a name conflict, remove the variable from memory with the clear function.
Another potential source of name conflicts occurs when you define a function that calls load or eval (or similar functions) to add variables to the workspace. In some cases, load or eval add variables that have the same names as functions. Unless these variables are in the function workspace before the call to load or eval, the MATLAB parser interprets the variable names as function names. For more information, see:

WASHINGTON: Scientists have rediscovered what they claim is the eighth wonder of the world -- Pink and White Terraces in New Zealand, which were buried in mud for a 100 years, losing some charm.
Until the late 19th century, the Pink and White Terraces along Lake Rotomahana on the North Island, attracted tourists from around the world, interested in seeing beautiful natural formations created by a large geothermal system.
But the eruption of Mt Tarawera on June 10, 1886, buried the terraces in sediment and caused the lake basin to enlarge, engulfing the land where the terraces stood. For more than a century, people have speculated whether any part of the Pink and White Terraces survived the eruption.
Now, an international team has located portions of the long-lost Pink and White Terraces, using autonomous underwater vehicles (AUVs) to map the bottom of Lake Rotomahana.
Team leader Cornel de Ronde of GNS Science in New Zealand said the scientists were elated by the rediscovery.
"The first sidescan sonar image gave a hint of a terraced structure so we scanned the area twice more and we are now 95 per cent certain we are seeing the bottom two tiers of the Pink Terraces," de Ronde said.
Side-scan sonar and bathymetric data collected by two REMUS 100 AUVs clearly show crescent-shaped terraced structures in about 60 meters of water where the Pink Terraces were located prior to 1886; they are covered by a brownish lake sediment, say the scientists.
After detecting areas of interest with the AUV's sonar systems, the team used the underwater camera system to capture images of the lake floor where they were able to photograph some of the stepped terrace edges.

An immigrant who is considered an "outstanding researcher or professor" may qualify for a EB-1B visa. The immigrant must be internationally acclaimed in his/her scientific or scholarly field of work.
Unlike EB-1A Visas, EB-1B immigrant visas must be employer sponsored meaning that the professor or researcher must have sponsorship from his/her employer throughout the petitioning process in order to receive a EB-1B Visa. Through the petition process, the employer becomes the petitioner and the immigrant receiving the EB-1B Visa is the beneficiary.
You must demonstrate international recognition for your outstanding achievements in a particular academic field. You must have at least 3 years' experience in teaching or research in that academic area. You must be entering the United States in order to pursue tenure or tenure track teaching or comparable research position at a university or other institution of higher education.
To be recognized internationally as an Outstanding Researcher or Professor in one's field requires at least two (2) of the following types of evidence:
- Evidence of receipt of major prizes or awards for outstanding achievement
- Evidence of membership in associations that require their members to demonstrate outstanding achievement
- Evidence of published material in professional publications written by others about the alien's work in the academic field
- Evidence of participation, either on a panel or individually, as a judge of the work of others in the same or allied academic field
- Evidence of original scientific or scholarly research contributions in the field
- Evidence of authorship of scholarly books or articles (in scholarly journals with international circulation) in the field
Applying for a EB-1B can be a grueling and involved process to provide enough evidence that you have been recognized internationally in your work. Be prepared for all situations by having a lawyer by your side. It is crucial to have an experienced professor and researcher visa immigration lawyer by your side to help you through the application process to make sure that you have met all the required criteria to be granted a EB-1B Visa.

Import duplicate company data to use for testing [AX 2012]
Updated: February 1, 2013
In Microsoft Dynamics AX 2009, the duplicate company feature was used extensively to copy data from one company to another. The feature was also used to build development or test environments, and deployment scenarios that moved data from one environment to another. However, this feature became obsolete in Microsoft Dynamics AX 2012.
We recommend that you use the Microsoft Dynamics AX data export and import feature to support scenarios that previously required the duplicate company feature.
Company, or DataArea, can no longer be used as a data security boundary. Because of changes that were made to the organization model in Microsoft Dynamics AX 2012, data is no longer related to a company or legal entity in a simple relationship that is defined by setting the SaveDataPerCompany metadata property of a table to Yes. Because data relationships are now defined through the Relations metadata property, it is not easy to duplicate all data that is related to a legal entity. Therefore, it may not make business sense to duplicate the data that is related to a legal entity. For example, we created organizational hierarchies in which legal entities and business units have a complex relationship. There is no parent/child relationship between business units and legal entities. Therefore, the duplication of business units based on legal entities in the system is erroneous.
Follow these steps to use an existing legal entity as a template for other legal entities.
 1. Create a legal entity to use as a template.
 For more information, see Create or modify a legal entity.
 2. Set all configuration data for the legal entity.
 3. Use the Microsoft Dynamics AX data export and import feature to export the legal entity to a.dat file, such as TMP.dat.
 1. Before you export data, you must create a definition group.
 For more information, see Create definition groups for import and export.
 2. To export configuration data, include the following table groups: Reference, Parameter, Group, Framework, and Miscellaneous.
 To export master data, you must also include the tables that are in the Main table group.
 Do not include the tables that are in the Transaction, Transaction header, Transaction line, Worksheet, Worksheet header, and Worksheet line table groups. These tables include transaction data.
 For a detailed list of all the tables in a table group, see Table group reference.
 4. In the new environment, create new legal entities, and then import the.dat file that you created into each entity individually.
 Shared and per-company data is imported. When other legal entities are subsequently imported into the new legal entities, the shared data is merged.
 For more information, see Import data from another instance of Microsoft Dynamics AX.
You can use the Microsoft Dynamics AX data import and export feature to import and modify transaction data. However, it can be difficult to create a duplicate environment for transaction data if the SaveDataPerCompany property of tables is set to No. Instead, we recommend that you use the backup and restore functionality in Microsoft SQL Server to build demo environments in which minor configuration changes can be made to illustrate specific Microsoft Dynamics AX features.

Sales Cycle - The Timeline From Making Contact With A Prospect To Finalizing The Sale
Sales Cycle
What is the definition of a sales cycle? A sales cycle is the time from when a salesperson first makes contact with a prospect to the moment when a sale is made or finalized. For example, if a copier sales rep makes a cold call from a list of prospects and reaches one, that is the start of the sales cycle. When she finalizes the deal and makes delivery of the copier that is the end of the sales cycle. The time in between the initial cold call and delivery is the sales cycle.
How long should a sales cycle be? That is a question that cannot be answered without including dozens of other variables. A sales cycle could be one day, or it could be one year or more; it all depends on the industry, the market, the individuals involved, and dozens of other factors.
As a general rule, the larger the deal or the more complicated the product or service, the longer the sales cycle will be. A tire salesman selling tires could go through multiple sales cycles a day, whereas a firm engaged in say, million dollar deals with the government, will face many more challenges, including tendering to RFPs (request for proposals), sales presentations, and reports; a sales cycle like this could last for months or even years.
It is a goal of many sales organizations to move propects through sales cycles as quick as possible. The more efficient the sales cycle, the more prospects will go through, the more sales that will be made. More sales equals more revenue. Thus, an efficient sales cycle provides benefits for the organization and many organizations provide sales training for their staff to help them improve their own personal sales cycle with their cliants and prospects.
A sales cycle is sometimes also referred to as the gestation period.


Webinar: Air Technical Modeling predicting System Performance.
Using Air Technical Simulations for Better Balanced dust and vapor extraction Systems. Data-driven air technical modeling, lab results and factory measurements contribute to building economical dust & vapor extraction systems that are reliable over the long term with a truly meaningful process guarantee.
Why air technical (GCM) Modeling?
Industrial dust collection and ventilation systems are relatively easy to build but very hard to operate in a stable, reliable, and efficient manner. That is, if the system has not been modeled beforehand and pressure drop measurements and optimal extraction velocities/ piping diameters are not calculated or simulated properly.

Scientists propose storing DNA 'ark' on the Moon to preserve our planet
Written on 03/15/2021
By Ciarán Mather
It would seem that some scientists are planning to give a futuristic twist to the old phrase 'don't keep all your eggs in the one basket.'
A group of researchers have suggested sending an 'ark' full of DNA from Earth, consisting of various types of sperm, eggs and seeds from plants.
In their proposal, they outlined that this 'gene bank' would be hidden inside the moon's lava tubes: hollowed-out tunnels and caves sculpted by lava more than 3 billion years ago inside the moon.
In addition, the banks would be powered by solar panels.
Jekan Thanga, head of the Space and Terrestrial Robotic Exploration (SpaceTREx) Laboratory at the University of Arizona, explained his team's back-up plan to LiveScience: 'There's this strong interconnectedness between us and nature. '
'We have a responsibility to be guardians of biodiversity and [to also be] the means to preserve it.'
He added the lunar ark approach is preferable to simply preserving it on Earth, in the event of our planet potentially succumbing to a disastrous event such as a super-volcano or even nuclear war.
The ark would hold the cryogenically (frozen) genetic material of all 6.7 million known species of plants, animals and fungi on Earth.
This would require at least 250 rocket launches to transport the cargo to the moon from Earth, according to researchers.
Not all the technology needed for this ambitious project exists yet, but the researchers think that it could realistically be built within the next 30 years.
The idea of an ark containing Earth's DNA echoes similar concepts seen in science fiction stories before, such as in 2017's Alien: Covenant.

How to Protect Linux against Rogue USB Devices Using USBGuard
SBGuard is a Linux kernel module that allows you to create policies for USB devices based on their attributes. It can be used to prevent rogue USB devices from being connected to your system, as well as to block certain types of USB devices based on your security needs.
Install USBGaurd Package
To use USBGuard on your Linux system, you will need to install the usbguard package. This package is available in most Linux distributions and can be installed using the package manager. For example, on a Debian-based system, you can install it using the following command:
sudo apt-get install usbguard
Once the package is installed, you can start the USBGuard service by running the following command:
sudo systemctl start usbguard
You can then configure the USBGuard rules by editing the /etc/usbguard/rules.conf file. This file contains a set of rules that define how USBGuard should handle different types of USB devices.
For example, to block all USB storage devices, you can add the following rule to the file:
block with-interface equals {08:*}
This rule will block any USB device that has an interface class of 08, which corresponds to storage devices.
You can also create rules that allow certain types of devices based on their attributes. For example, to allow a specific USB keyboard, you can use a rule like this:
allow with-serial equals "123456"
This rule will allow a USB keyboard with the serial number "123456". You can use similar rules to allow other types of devices, such as printers or mice.
Once you have created your rules, you can reload the USBGuard rules by running the following command:
sudo usbguard reload-rules
This will apply the new rules and block or allow the appropriate devices.
Conclusion
By using USBGuard, you can protect your Linux system from malicious USB devices. USBGuard's access control feature allows you to specify exactly which USB devices can access your system. However, it's important to remember to use other security measures as well.

A case-control study on Alzheimer's disease and exposure to anesthesia
- First Online:
A retrospective hospital-based case-control study was performed with the aim to evaluate the association between exposure to anesthesia and Alzheimer's disease (AD). A total of 115 AD patients, 230 Parkinson's disease (PD) patients and 230 patients with non-degenerative neurological disease were studied. Each AD case was matched for sex, age (±3 years) and geographic area of residence with four controls (2 PD patients and 2 with other neurological disease). Information about exposure to general anesthesia and other variables was gathered through hospital records. No associations were found between the risk of AD and the exposure to anesthesia in the 1 and 5 years preceding disease onset, nor between the risk of AD and the number of surgical operations. A significant difference was observed between the mean age of AD patients and controls undergoing surgical procedures. The present study reveals a lack of association between exposure to general anesthesia and AD. Prospective epidemiological studies are needed in order to investigate levels of exposure to anesthesia, as well as any possible relationships between anesthetic exposure and genetic factors (e. g. APOEɛ4 genotype).
