Trail Blazers: The Blazers have been knocked down a few times this season, but they've always found a way to get back on their feet and offer a response. While they still have a good chance of advancing to the next round, the Nuggets might end up regretting basically giving away Game 4. Now, the series shifts back to Denver all knotted up at 2-2. Malone wanted to make sure his team, coming off a nine-day. They never led, and trailed by as much as 33 at one point. DENVER - Hours before Thursdays Game 1, head coach Michael Malone gave the Denver Nuggets a pop quiz at the teams morning shootaround. In the playoffs, they are 9-0 SU and 6-1 ATS.

CNN previously reported that Biden Biden's plan is to increase the public health workforce to support the vaccination effort, which includes allowing for additional professionals to administer vaccines and encouraging states to expand the scope of practice laws and waive licensing requirements where appropriate. ![]() "President-elect Biden's plan will release the vast majority of the vaccines when they are available, so more people can get vaccinated quickly, while still retaining a small reserve for any unforeseen shortages or delays," the fact sheet reads. As Biden has pledged in the past, he will use use the Defense Production Act to maximize the manufacturing of the vaccine and increase the supply. Biden's plan will make vaccines available in pharmacies, and increase the capacity at chain and independent pharmacies across the nation. He will use federal funds to create new community vaccination centers across the country, and launch mobile vaccination clinics and provider partnerships to reach underserved urban areas and rural communities. The President-elect's plan will focus on ensuring equitable access to the vaccine, with a focus on reaching marginalized communities that have been hit hardest by the pandemic. Next in line are older adults, ages 75 and older, and "frontline essential workers," including first responders, the advisers recommended. The fact sheet continues, "President-elect Biden's plan encourages states to open up eligibility beyond healthcare workers and long-term care facility residents and staff, to include frontline essential workers like teachers, first responders, grocery store employees, and anyone who is 65 and older."Health care workers and residents of long-term care facilities are the first in line for the coronavirus vaccines, as recommended by vaccine advisers to the CDC. We now see doses of vaccines sitting in freezers unused while people who want the vaccine cannot get it," a fact sheet provided by the Biden transition team reads. Biden's plan to vaccinate the country includes opening up eligibility to get more people vaccinated, creating more vaccination sites, increasing supply and distribution of the vaccines, mobilizing more personnel to support the vaccination effort, and launching a public education campaign to address those hesitant to take the vaccine."The process of establishing priority groups was driven by science, but the implementation has been too rigid and confusing. ![]() ![]() ![]() Graphics cards are optimized for graphical calculations and transformations.

The adaptation to the Regulation by catering companies has substantially improved the menus as compared to previous times: more presence of vegetables, better quality of fat and less amount of fat and proteins at the expense of carbohydrates.QTS is the operating system for entry- and mid-level QNAP NAS. The energy and nutrient content was determined and the fatty acid composition was analysed. For this, at each centre a duplicate of the portion served that day was gathered. So far, a random sample of 171 schools with dining rooms (more than 37,000 schoolboys) has been visited by nutritionists, with no previous announcement, to control served menus. This work describes the adaptation of programmed dietary schemes of officially approved companies and mainly the impact on energy and nutritional content of menus and their adaptation to the recommended caloric and lipidic profiles. Collective catering companies were called for a tender to provide menus adapted to such Regulation. The Spanish Nutrition Foundation (FEN) and the Nutrition Department of the Complutense University of Madrid (UCM) were put in charge of elaborating the bases to develop the Regulation (BOCM 24-05-01, 10-09-02). The Education Council of the CM considered necessary to plan and regulate the basic conditions that menus of these dinning rooms should meet. Some nutritional unbalances have been observed in menus served at dining rooms of schools from the Community of Madrid (CM): small portions, inter-day variations up to 50% of energy intake, unbalances in caloric and lipidic profiles, little variety, lack of parental information, etc. ![]() ![]() ![]() However, in the latter study, this effect was particularly observable in participants with positive psychosocial attributes.ĭe la Haye and colleagues were able to show that close friends in adolescent friendship networks have a significant influence on each other regarding a number of health related behaviours, especially the physical activity behaviour was “ found to be similar”. confirm the impact of social networks and social support on the degree that people are physically active. Mc Neill, Kreuter, and Subramanian identify five modifiable dimensions of the social environment that have an influence on the activity status of a person: firstly, social support and social networks secondly, socioeconomic position and income inequality thirdly, racial discrimination fourthly, social cohesion and social capital and fifthly, neighbourhood factors. note that physical activity is associated with individual social participation and neighbourhood interpersonal trust. The studies in unison report that a high socioeconomic position (including occupational position, income and educational level) positively correlates with a higher degree of physical activity in leisure time.įurther studies also analysed the effects of social networks on the willingness of an individual to be physically active. Most studies in this regard have analysed socioeconomic correlates of physical activity, particularly the socioeconomic status. In the last ten years, public health research has paid increased attention to determinants of physical activity in order to fight the pandemic development of non–communicable diseases. In order to promote physical activity, future health initiatives should target these factors of a person’s network. Our study shows that several social factors determine the physical activity of very active and very inactive groups. Obese people were particularly inactive when they were members of frequently communicating, age-heterogeneous groups. Such interacting factors were for example the degree of communication within the group, the gender- and age-related composition of the group, but also the equipment that had been brought to the beach/pool. The identification of six contrasting clusters highlights that besides the body shape several factors interact regarding a group’s physical level. ![]() Yet, classification tree analysis reveals that obesity itself does not necessarily determine physical inactivity levels. ![]() While obese groups had the lowest average activity level, groups mainly consisting of people with an athletic body shape were the most physically active. General statistical analysis shows that, overall, the most differentiating factor regarding physical activity was the body shape of the group members. For this, we conducted a classification tree analysis. To better understand activity promoting and hindering mechanisms, special attention is given to the identification of contrasting factors that characterise groups which are very active or very inactive. For the general statistics, we accessed the significance of differences regarding the degree of physical activity dependent on the target variables. In total, we observed 907 groups with the groups’ size varying between 2 and 8 members. Total observation period was eight and a half months. We recorded the physical activity of face-to-face interacting groups and analysed categories such as group size, estimated age of the group members, and verbal communication patterns. This study presents the quantitative data of a systematic (covert) participant observation. In order to consider the context in which physical activity occurs and to investigate whether cultural settings may influence physical activity, we conducted the study at pools in different cultural environments - Hawai’i and Germany. This field study aims to investigate the determinants of physical activity of particularly active and inactive groups in their leisure environments. ![]() ![]() ![]() Charles Darwin described it as an arid treeless island, with nothing growing near the coast. In 1836 the second Beagle voyage visited Ascension. A garrison of Royal Marines was based at Ascension from 1823 and Colonel Edward Nicolls became the first commandant. The Royal Navy used the island as a victualling station for ships, particularly those of the West Africa Squadron working against the slave trade. The location of the island made it a useful stopping-point for ships and communications. Royal Marine barracks (1830) in the former Royal Dockyard, Georgetown The Royal Navy designated the island as a stone frigate, HMS Ascension, with the classification of "Sloop of War of the smaller class". On 22 October the Cruizer-class brig-sloops Zenobia and Peruvian claimed the island for King George III. Organised settlement of Ascension Island began in 1815, when the British garrisoned it as a precaution after imprisoning Napoleon on Saint Helena to the southeast. His diary was published in translation in London later that same year, under the title Sodomy Punish'd. ![]() British mariners found the Dutchman's tent, belongings and diary in January 1726 the man's remains were not found. It is possible, but disputed, that the island was sometimes used as an open prison for criminal mariners, although there is only one documented case of such an exile, a Dutch ship's officer, Leendert Hasenbosch, set ashore at Clarence Bay as a punishment for sodomy in May 1725. Almost certainly, after a few days they found the strong water spring in the high interior of the island, in what is now called Breakneck Valley (there is a much smaller water source, lower on the mountain, which was named Dampier's Drip by people who probably misinterpreted Dampier's story). Sixty men survived for two months until they were rescued. In February 1701, HMS Roebuck, commanded by William Dampier, sank in the common anchoring spot in Clarence Bay to the northwest of the island. The Portuguese also introduced goats as a potential source of meat for future mariners. Mariners could hunt for the numerous seabirds and the enormous female green turtles that laid their eggs on the sandy beaches. Dry and barren, the island had little appeal for passing ships except for collecting fresh meat, and was not claimed for the Portuguese Crown. On March 25, 1501, the Portuguese navigator João da Nova sighted the island on Ascension Day (which fell on 21 May that year) and named it Ilha da Ascensão after this feast day. João da Nova discovered the island on Ascension Day 1501. NASA operates a Meter Class Autonomous Telescope (MCAT) on Ascension Island for tracking orbital debris, which is potentially hazardous to operating spacecraft and astronauts, at a facility called the John Africano NASA/AFRL Orbital Debris Observatory. Ascension Island hosts one of four ground antennas that assist in the operation of the Global Positioning System (GPS) navigational system (the others are on Kwajalein Island, Diego Garcia, and Cape Canaveral). The island was used extensively as a staging point by the British military during the Falklands War. The island is the location of RAF Ascension Island, which is a Royal Air Force station, a European Space Agency rocket tracking station, a British-American signals intelligence facility and the BBC World Service Atlantic Relay Station. During World War II, it was an important naval and air station, especially providing antisubmarine warfare bases in the Battle of the Atlantic. ![]() Ascension Island was garrisoned by the British Admiralty from 22 October 1815 to 1922 and was an important refueling stop for ships and commercial airliners in the days of international air travel by flying boats. The territory also includes the sparsely populated Tristan da Cunha archipelago, 2,300 miles (3,700 km) to the south, about halfway to the Antarctic Circle.Īscension Island was discovered by the Portuguese navigator João da Nova in 1501 and named Conception Island, but was rediscovered in 1503 on Ascension Day by Alphonse de Albuquerque and renamed. It is governed as part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, of which the main island, Saint Helena, is around 800 miles (1,300 km) to the southeast. It is about 1,000 miles (1,600 km) from the coast of Africa and 1,400 miles (2,300 km) from the coast of South America. Ascension Island is an isolated volcanic island, 7★6′ south of the Equator in the South Atlantic Ocean. ![]() ![]() ![]() Windows software that supports MIDI and audio sequencing.

I have always just listened more to the arrangement on a skeletal track to make sure it right before I put it over into Cakewalk to add tracks, choose sounds for each track, etc. The Anvil is less so, as to me, it's just a lightweight auditioning tool. Of course, to make it sound MUCH BETTER, you'll have the capabilities, if you take some time to learn. The Cakewalk IS a full DAW, which you said you rerally didn't want, but nothing says you can't just set it up, load up files and start playing. to sound more like an imperfect real drummer.Īnyway, there are two possibilities, if looking for a software solution. There are many CAL routines that are handy, such as "Randomize" which can impart a more-real feel to a robotic track by introducing slight timing variations, or randomizing things like Hi-Hat or snare velocities, etc. MIDI is a serial protocol, so the more CC data it has to send means other data may get sent later, or if you have several tracks using a ton of dtata, it can even "choke" the sound module, making it get stuck on a note, stop, whatever. The same apparent "Pitch shifting" can occur using MUCH less data by "Thinning Data". If you have a MIDI track that has used a pitch or modulation wheel or some other continuous controller being moved, it generates a tremendous amount of data. What those can do is automate an edit, such as "Thin Data". The thing about Cakewalk is its extensive MIDI editing, with all the Piano Roll, Event List, Staff editing, etc, plus the very helpful CAL (Cakewalk Application Language) routines that are a tremendous help. Plus, this one WILL allow you to add some actual audio tracks, if you wish. It IS fairly complicated, but it can also be used fairly easily, if using just the basics. You do have to sign up for Bandlab to download it, but nothing says you have to use real info, and there is no ask for credit card, or no nags.Ĭakewalk/Sonar has been my favorite for decades. The other is the now-free version of Cakewalk from Bandlab. Maybe that could chain together some for performance? I don't know if it has any kind of "chain" or "playlist", though it does have an "Open Playlist" option. The free version will play the MIDI unlimited, but only two 2-minute audio tracks, which wouldn't be a problem if only playing back MIDI. It does have some basic editing, with the typical Event List Editor, Piano Roll Editor, Staff Editor, etc. I have it on my computers just to audition any MIDI tracks.

As always, this is a balance between security and useability and administration so bear in mind and use this with caution. You can use path rules as of Windows 10 version 1903. You can have multiple policies complementing each other so that you do not have to sign everything nor have to create an entirely new baseline each time you want to allow new things to run. The reason for this it being rather easy to manage now is primarily: This takes application whitelisting to a new level and with Windows 10 version 1903 it becomes the first time since Windows 10 launched that it is actually usuable in many common day scenarios as the administration can now be on a level which is really to manage. What is superior to AppLocker is Microsoft Defender Application Guard (MDAC). One of them being using regsvr32 to download and execute script directly from the internet for instance.

Enter a 1 for each binary place value that was found, and a 0 for the rest.Find the largest power of 2 within the remainder found in step 2.Subtract that value from the given number.Find the largest power of 2 that lies within the given number. ![]() The step by step process to convert from the decimal to the binary system is: Since 2 3 = 8, a 1 is entered in its position yielding 1000. Reading from right to left, the first 0 represents 2 0, the second 2 1, the third 2 2, and the fourth 2 3 just like the decimal system, except with a base of 2 rather than 10. In the decimal number system, 8 is positioned in the first decimal place left of the decimal point, signifying the 10 0 place. While working with binary may initially seem confusing, understanding that each binary place value represents 2 n, just as each decimal place represents 10 n, should help clarify. Using a decimal system would require hardware that can detect 10 states for the digits 0 through 9, and is more complicated.īelow are some typical conversions between binary and decimal values: It is much simpler to design hardware that only needs to detect two states, on and off (or true/false, present/absent, etc.). Apart from these differences, operations such as addition, subtraction, multiplication, and division are all computed following the same rules as the decimal system.Īlmost all modern technology and computers use the binary system due to its ease of implementation in digital circuitry using logic gates. Furthermore, although the decimal system uses the digits 0 through 9, the binary system uses only 0 and 1, and each digit is referred to as a bit. While the decimal number system uses the number 10 as its base, the binary system uses 2. The binary system is a numerical system that functions virtually identically to the decimal number system that people are likely more familiar with. Related Hex Calculator | IP Subnet Calculator ![]() ![]() ![]() The above values illustrate a pattern: as the separation distance is doubled, the electrostatic force is decreased by a factor of four. The inverse square relationship between electrostatic force and separation distance is illustrated in the table below. This square effect makes distance of double importance in its impact upon electrostatic force. And if the separation distance is tripled (increased by a factor of 3), then the electrostatic force is decreased by a factor of nine (3 raised to the second power). So if the separation distance is doubled (increased by a factor of 2), then the electrostatic force is decreased by a factor of four (2 raised to the second power). That is, the factor by which the electrostatic force is changed is the inverse of the square of the factor by which the separation distance is changed. Careful observations show that the electrostatic force between two point charges varies inversely with the square of the distance of separation between the two charges. The pattern between electrostatic force and distance can be further characterized as an inverse square relationship. ![]() Electrostatic force and distance are inversely related. In a similar manner, charged balloons are observed to exert their greatest influence upon other charged objects when the separation distance is reduced. Yet if the tube is brought closer, an attractive interaction is observed and the strength is so significant that the paper bits are lifted off the table. The electrical interaction is so small at large distances that the golf tube does not seem to exert an influence upon the paper bits. Consider a charged plastic golf tube being brought near a collection of paper bits at rest upon a table. These observations are commonly made during demonstrations and lab experiments. Electrical forces are extremely sensitive to distance. ![]() And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Inverse relationships are common in nature. This type of cause-effect relationship is described as being an inverse relationship. Observation might also indicate that an increase in one variable always causes another measurable quantity to decrease. This type of cause-effect relationship is described as being a direct relationship. Careful observation and measurement might indicate that a pattern exists in which an increase in one variable always causes another measurable quantity to increase. This search for cause and effect often leads to conclusive evidence that two variables are causally related (or not causally related). How does the distance between two charged objects affect the force of attraction or repulsion that they encounter? How does the frequency of a sound wave affect the speed at which the sound wave moves? How does the distance from a page to a light bulb affect the amount of light that illuminates the paper's surface? How does the speed of a falling object affect the amount of air resistance that it experiences? How does the mass of an object affect its acceleration? The goal is to answer the question of how does a change in a set of variables or conditions causally affect an observable outcome? In Physics, this search for cause and effect leads to questions like: How does a force affect the acceleration of an object? Scientists modify a set of conditions to see if there is a pattern of behavior in another set of measurable quantities. Nature is probed in order to find relationships and mathematical patterns. Cause and effect is the focus of science. Science in general and Physics in particular are concerned with relationships. ![]() |
