The raw material is fed into the dryer from the feeding inlet and the material will continuously moving along with the fluidized bed level under action of vibration. The hot air passes through fluidized bed and carries out heat exchange with damp raw materials. The wet air is exhausted out by the cyclone separator and the dried material will be discharged from the discharge outlet.
1) The vibration is created by vibrating motor which is stable in operation, easy for maintenance, low noise, and long service life.
2) The material is being heated evenly and the heat exchange is fully used which ensured high drying capacity. The energy consumption is 30% lower compare to the common dryers.
3) The adjustability of the dryer is good and it is widely used in different industries. The material thickness, moving speed inside the dryer, and amplitude can be adjusted.
4) The damage to the material surface is small so the dryer can be used for fragile materials. The irregular particles will not affect performance of the dryer.
5) A fully enclosed structure will effectively prevent cross contamination between the material and the air environment.
6) Multiple series connection is optional if the material contents high moisture and required high capacity; such as Polyacrylamide.

Through continuous exploration and practice, the company has developed the advantages of low investment, high efficiency, low operation cost, high product quality and convenient control and operation. The microwave frequency thawing equipment with microwave frequency of 915MHz and output power of 20kw-200kw is above. For food processing enterprises such as chain fast food industry in China, food thawing is provided, and the improvement of food thawing technology in China is also renewed. The benefit is not only "farsightedness", but also at the foot of the eyes. According to experts, the traditional food thawing are based on heat conduction method, material surface temperature is higher than the internal temperature in the thawing process, inevitably there will be drop loss, which will increase the business loss. If merchants use microwave dryer, Vibration microwave Model Fluid Bed Dryer for Mining Slag power, material temperature and transmission speed can be used to achieve adjustable linkage, and the overall heating process control advantages can greatly reduce material consumption and improve food utilization. In addition, as the microwave thawing only needs electricity, no need to consume a lot of water, in the low carbon era, this is not lost a recommended fashion trend.
microwave dryer is a new type of environmental protection drying method. When dry, Vibration microwave Model Fluid Bed Dryer for Mining Slag directly to the medium molecules converted into heat, because the Vibration microwave Model Fluid Bed Dryer for Mining Slag penetrating performance of heating medium and at the same time, no need to heat conduction, so the heating speed is very fast, the water content below 30% of the food, the drying speed can be shortened hundreds of times.
Conventional thermal sterilization is used to transmit heat from the surface of the food to the interior through heat conduction, convection, or radiation. It often takes a long time to get the germicidal temperature. The Vibration microwave Model Fluid Bed Dryer for Mining Slag is the direct interaction between microwave energy and microorganisms such as food and bacteria. The interaction between heat effect and non thermal effect can achieve fast warming and bactericidal action, and the processing time is greatly reduced. The sterilization effect of various materials is usually 3-5 minutes.
2, Vibration microwave Model Fluid Bed Dryer for Mining Slag low temperature sterilization keep the nutrition and traditional flavor The Vibration microwave Model Fluid Bed Dryer for Mining Slag is through special heat and non thermal effect sterilization, compared with conventional thermal sterilization, it can get the desired disinfection effect at relatively low temperature and short time. Practice shows that the general sterilization temperature can reach the effect at 75-80 degrees centigrade. In addition, microwave dryer processed foods can retain more nutrients and color, aroma, taste, shape and other flavors, and have puffing effect. For example, the vitamin C retained in vegetables treated by conventional heat treatment is 46-50%, while that in microwave treatment is 60-90%, while that in conventional heating is 58%, while that in microwave heating is 84%.
3 microwave dryer and Vibration microwave Model Fluid Bed Dryer for Mining Slag save energy Conventional thermal sterilization often has heat loss in the environment and equipment, and microwave is directly treated to food, so there is no extra heat loss. In addition, the conversion efficiency of the electric energy to the microwave energy is in the 70-80%, and the power is generally reduced to 30-50%.

Apple's future campus will fit right in with other corporate giants and tech firms that have invested in offices and campuses along Parmer Lane. The influx in new offices has also led to other ancillary or secondary development, such as apartments, hotels and retail space, mostly near these corporate campuses.
Sources: Apple, CBRE Group, Travis Central Appraisal District/Community Impact Newspaper
With 5,000 new jobs coming to Northwest Austin in the next few years, many residents wonder how Apple's second campus will affect housing prices and traffic.
Apple announced Dec. 13 it will invest $1 billion to build a 3 million-square-foot second campus on a 133-acre tract of land on the Robinson Ranch property northeast of the intersection of Parmer Lane and McNeil Drive. Apple officials stated they will initially hire 5,000 new employees but that the campus could hold up to 15,000 people.
Austin officials praised the announcement for the new jobs it will bring, including Mayor Steve Adler, who said the city and Apple share a "creative spark" and a commitment to diversity and inclusion.
"I think this is really important for Austin, for its mobility issues and for its housing issues," Austin Mayor Steve Adler told Community Impact Newspaper on Dec. 13. "We need more than one downtown center. We need more activity centers in the city, and I think this kind of activity is how we move toward that. The Domain's turning into one. Robinson Ranch needs to be one as well."
Jimmy Flannigan, City Council member for District 6, where the new campus will be located, said the effect of Apple investing in Austin could be huge for taxpayers.
"What we know when we look at the tax base is when you have significant commercial development it really helps fund all of the other things the community is asking for: transportation improvements, parks improvements and frankly helps keep the tax rate a little bit lower, especially when the city is not giving a subsidy to this campus," he said.
Williamson County approved a $16 million, 15-year incentive agreement Dec. 18 with Apple to reimburse 65 percent of the company's property taxes.
Drawn to Northwest Austin
For the past several decades the Northwest Austin area has attracted attention from tech firms that have opened offices or large campuses. Apple has leased space at 12545 Riata Vista Circle for years, and in 2012 the company announced plans to build its Americas Operations Center adjacent to its office on Parmer Lane on 38.8 acres of land. Under an incentive deal with the city of Austin, Apple agreed to build
1 million square feet of office space and create at least 3,600 new jobs.
Other corporate campuses have also sprung up on Parmer over the years. The 7700 Parmer campus is primed to nearly double to almost 2 million square feet of office space thanks to Austin City Council approving its proposal in 2017.
Williamson County Commissioners Court approved 14 early voting locations for the Nov. 5 elections July 16. During the recent 86th... >
Farther east, the Parmer Austin corporate center, while still under development, is also home to corporations such as GM, The Home Depot and pharmaceutical company Allergan. In 2019, 3M will relocate its 800 employees to Parmer Austin. Mark Emerick, senior vice president of real estate firm CBRE's Austin office, which handles the leasing at Parmer Austin, told Community Impact Newspaper in July that many companies are interested in Parmer Lane.
"When you look at the park and see Home Depot, 3M, Allergan, GM and Dell across the street—four Fortune 500 companies—that's making a statement," Emerick said.
Apple's next steps include submitting site permits to the city of Austin, starting site preparation and installing utilities. Kristina Raspe, Apple's vice president of local real estate, said the company expects to have its first buildings operational in 2021.
Impact on traffic
Over the past five years traffic counts along Parmer Lane have not increased significantly. Data from the Texas Department of Transportation shows only an 8.2 percent increase in the number of average daily vehicles, from 40,582 in 2013 to 43,920 in 2017.
The state agency is not planning any projects on Parmer between SH 45 N and I-35. However, it plans to begin construction in 2019 on a project at I-35 to convert the intersection at Parmer to a diverging diamond interchange. North of SH 45 N, TxDOT will expand Parmer to six lanes in a project being partially financed through the 2016 Mobility Bond.
Capital Metro also reported adding an infill MetroRail station near the Apple campus is not likely in the short term because the track's alignment is on the eastern side of the Robinson Ranch property while Apple's proposed campus is on the western side, spokeswoman Mariette Hummel said.
However, the transit agency did add Parmer Lane to its high-capacity transit vision map called Project Connect to study adding some form of bus-rapid transit on Parmer.
Williamson County Commissioner Cynthia Long said she is using the Apple deal to fast-track improvements, such as adding managed or toll lanes to Parmer.
Rising costs?
Even with the increases in jobs and future tax revenue, many residents are also concerned about rising home prices.
Demand continues to outpace supply in Austin's real estate market, and the Northwest Austin area is "primed" for the arrival of the new Apple campus, Austin Board of Realtors President Steve Crorey said. Concerns remain, however.
"If we don't get serious about our infrastructure, our traffic, putting [more diverse]product on the ground for everyone, we're going to lose businesses like this," Crorey said.
Surrounding communities such as Leander and Liberty Hill are likely to see a spillover of new Apple employees buying households or filling rental properties as well as driving new development.
"Austin proper does not have a ton of land left to develop new homes," said Cindi Bell, president-elect for the Williamson County Association of Realtors.
Affordability and availability themselves may drive more incoming residents to Austin's suburbs out of sheer necessity, Realty Texas Realtor Suzanne Gantner said.
"If you're wanting to buy something in the Austin area the affordability right now is just crazy," she said.

Nashville state representative blasts special session after testing positive for COVID-19

State Rep. Bill Beck announced Thursday, Aug. 27, he tested positive for COVID-19 less than two weeks after attending a legislative special session and slammed state leaders for holding the three-day event.
Beck, a Nashville Democrat, is the fifth legislator known to have the virus, including House Minority Leader Karen Camper of Memphis. She left the special session on its first night, Aug. 10, after feeling ill but was never hospitalized and is back to 100%, according to her office.
Elected official recuperating after catching COVID-19
Beck said he immediately self-isolated when he started experiencing symptoms Sunday, Aug. 23, and underwent a test Monday at the Nashville COVID-19 assessment center at Nissan Stadium.
The symptoms started, he said, 11 days after the end of the special session called by Gov. Bill Lee to consider bills to clamp down on unruly protesters, give businesses immunity to COVID-19 lawsuits and approve a telehealth insurance system.
"I took great pains to be as safe as I could since COVID-19 first became a threat to Tennesseans, following all medical guidelines to minimize the spread of this debilitating virus, such as social distancing and wearing a mask," he said.
Karen Camper
" Unfortunately, staying safe is a group effort, and the General Assembly failed as a whole to follow the medical advice of wearing a mask and social distancing while in Nashville for the special session."
While Beck wore a mask during the proceedings, many legislators, most of them Republicans, declined to cover their mouths and noses.
Beck pointed out all "essential government business" was completed by the General Assembly in its regular session and that he and others felt the special session was unnecessary and "highly risky."
"We have been proven right on both accounts. I will be shocked if I am the only member who caught COVID-19 while attending a special session that did nothing but provide businesses with immunity from legitimate COVID-19 lawsuits and criminalize the right of our citizens to peacefully assemble and protest their government," he said in the statement.
He urged everyone to wear masks any time they leave their house to protect themselves and others.
Hamilton County state representative hospitalized with COVID-19
In addition to Beck and Camper, state Rep. Gary Hicks, a Rogersville Republican; state Rep. Mike Carter, a Hamilton County Republican; and state Rep. Kent Calfee, a Kingston Republican, have said they tested positive for the virus.
Carter did not attend the session and was hospitalized for several days. He said Thursday on Twitter he is out of the hospital and feeling better.
Calfee had tested positive weeks before the session and attended the meetings. Hicks announced last week he tested positive last week after going to the session.

n : a strong forceps for controlling bleeding in surgery having serrated blades with interlocking teeth at the tips
Koch•er, Emil Theodor (1841-1917), Swiss surgeon. Kocher spent virtually all of his career at the university surgical clinic at Bern. He made important contributions to the understanding of the physiology and pathology of the thyroid and the treatment of goiter occurring with and without hyperthyroidism. In 1876 he performed the first excision of the thyroid gland for the treatment of goiter; he published a description of his surgical procedure in 1878. Later, in 1883, he reported his discovery of a characteristic cretinoid pattern in patients after total excision of the thyroid gland. In 1878 he performed a successful drainage of a gallbladder, utilizing the forceps that have since become associated with his name. He also published in 1892 a textbook of operative surgery that remained a standard reference for many years. He was awarded the Nobel Prize for Physiology or Medicine in 1909.

81 turns of inverted flat spin was the new World Guinness Record achieved by American air show performer Spencer Suderman over the California desert flying his Pitts S-2B fully prepared for the occasion.
The previous world record holder was the stunt pilot Wayne Handley, who completed 78 rotations fifteen years ago. Suderman had tried to beat this record previously, but he failed in 2011 and 2013 with 64 and 77 turns respectively.
Spencer Suderman began his flying career while working on his Bachelor of Science degree in business at California State University Northridge in the late 1980's. He earned a private pilot's certificate, commercial rating, instrument rating, and then became a CFI (Certified Flight Instructor) in 2003. While working on his instrument rating in 2000, he went through a spin and unusual attitude training program. This training teaches pilots what to do in emergencies and involves mild aerobatics. Spencer soon discovered that aerobatics are amazingly fun and quickly lost interest in merely flying straight and level. After attending numerous aerobatic contests in the Super Decathlon Spencer moved up to the high performance Pitts S-2B which launched his career as an air show pilot in 2006. Now he taught to train other pilots his Be-A-Safe-Pilot training offered through the Torgoen Academy.
In the following paragraphs Spencer Suderman explains in Snap&Roll the conclusions from his experience after breaking the Inverted Flat Spin World Record.
On March 13, 2014 at 11:39 am PDT a new world record for most inverted flat spins performed in one attempt was set when 81 full turns were completed in a Pitts S-2B. The old record of 78 turns was anything but easy to beat and it took 3 attempts over the California desert to do it.
This spin was entered at 23,000' and the recovery initiated at 2,000', 3 minutes and 15 seconds later after which the plane returned to straight and level flight at 950'. This flight and all of its preparations were a data driven exercise in the research and development of aircraft configuration, pilot performance, problem solving and most important; flight safety.
11:39:21 79th turn completed at 2600'!
On March 10, 2011 after departing from the Naval Air Facility El Centro and climbing to 21,000' then entering the spin at 20,500' only 64 turns resulted.
On December 8, 2013 after departing from Naval Air Facility El Centro and climbing to 23,000' an unsuccessful attempt was made to enter the spin which resulted in falling out of the insipient phase of the maneuver, recovering at 20,000' then climbing back up to 22,000' and entering the spin at 21,600'. Only 77 turns resulted but this was still a big improvement from the previous attempt.
The gains in performance between the first 2 attempts were due purely to modifications on the engine and optimized tuning of the weight and balance of the plane for the intended purpose of the flight. The improvement in performance between attempts 2 and 3 was purely about how the flight was managed and the control inputs to enter the spin.
While an in-depth discussion comparing and contrasting the different types of spins is beyond the scope of this article and has been written about in great detail by several other prolific pilots/authors, I will simply remind everyone that spins are either upright or inverted then normal or accelerated and possibly aggravated but in all cases other than an inverted or upright power-on flat spin the airplane is still flying since there is laminar flow over the wings and tail. That is why a normal upright or inverted spin can be accelerated by using the elevator to decrease the angle of attack. It is important to understand that during a power-on inverted flat spin the plane is not flying but it simply falling and rotating due to thrust from the propeller and there is no manipulation of the flight controls that will increase the rate of rotation but certain flight control positions will actually slow it down. Of this fact I am certain because video documented tufting research performed during numerous inverted flat spins indicates that this is the case and emphasizes the importance of proper flight control positioning for maximum rate of spin.
The inverted flat spin is largely misunderstood by most aerobatic pilots as I have learned and requires a different way of thinking to understand what is happening and why. The biggest "A HA!" moment for me came when I realized that the propeller drives the maneuver through asymmetric thrust about the Longitudinal axis (nose to tail) rather than gyroscopic precession as I had thought.
When an airplane flies forward all of the propeller blades make thrust because the disk of the prop is mostly perpendicular to the airflow through the propeller. During the inverted flat spin the airplane is falling on its back (i.e.: dropping towards the ground at 65mph at 5000' agl) so the airflow is parallel to the disk of the propeller and, much like a helicopter in forward flight, one side of the disk has blades that are advancing into the airflow while the opposite side has blades that are retreating and approaching a condition known as "retreating blade stall". In effect they generate little or no thrust while the advancing blades generate most of the thrust which is what drives the maneuver and explains why you can only do an inverted flat spin with right rudder in a Lycoming powered airplane. After much experimentation (spins recorded on video) with various prop settings and throttle position it became quite apparent that high RPM and full throttle with the fuel flow (mixture) set for best power 100° rich of peak provided the highest spin rates.
Anyone who spins airplanes should be extremely comfortable with how to recover from all types of spins using both a normal proactive method and an emergency method but it has been proven that either recovery methods are virtually foolproof and perfectly reliable in the Pitts when executed correctly. PARE® is the acronym for Power(off)-Aileron(neutral)-Rudder(opposite)-Elevator(to neutral) and is the normal proactive method that works particularly well on the recovery of inverted flat spins, which is important if you plan to recover low.
Having opened my air show performance with inverted flat spins for years that start at 4500' with the recovery initiated at 2000' I have learned to perform PARE® so quickly and precisely that I can go from a full power-on inverted flat spin to a vertical down line in 400' then decide whether to pull out of that dive easy or hard as the situation calls for. In trying to break the inverted flat spin world record I knew that after hanging inverted and spinning down at -1.5G (indicated on the G-meter) for upwards of 3 minutes would require an easy pull from the vertical after the recovery to avoid a high positive G excursion that would cause GLOC (G induced Loss Of Consciousness).
In the interests of leaving no possibility on the table around the metal vs composite prop question I went flying in an S-2B that has the original Hartzell 2 blade prop and learned that it spins ½ turn per 1000' slower, documented with video of course, than an S-2B with the MT 3 blade composite prop, so that put the metal prop idea to rest. This should come as no surprise since one of the many advantages of composite props in aerobatics is the lower gyroscopic rigidity in space due to the reduction in weight at the tips.
Now that I was focused on the engine I called the man who knows more than anyone about aviating in the highest flight levels in a small piston powered airplane; Bruce Bohannon. Bruce holds many world records including the one I wanted to hear about the most; highest altitude (47,067') for a piston airplane in Class C1.b (takeoff weight between 1102# and 2201#). We talked about twin turbos, nitrous oxide injection and all sorts of things that are almost guaranteed to turn expensive machinery into a boat anchor within a few hours of assembling it but might be useful long enough to break a record. Of course the airplane itself is still the wrong airframe for this type of flying but the right tool for the job of inverted flat spinning.
As the conversation meandered through the possibilities we identified the biggest return on investment by advancing the magneto ignition timing from 25° btdc to 40° btdc with the caveat that full power could only be applied after climbing through 10,000' or the engine would detonate itself on takeoff. The other consideration in this approach was managing the power on the rapid descent during the spin and that would have been the biggest challenge. The other option would be electronic ignition with automatically variable timing but nothing was on the market at the time for the Lycoming IO-540 in a certified plane so I considered learning how to precisely and quickly readjust the magnetos on a regular basis.
Around this time in October of 2012 I read a press release from Electroair of Howell Michigan about developing an STC'd electronic ignition system for 6 cylinder Lycoming engines to complement the STC already obtained on their system for 4 cylinder engines. I called the president of the company and told him my story, listened to his story and we decided to work together in a flight test program that was written about in the August 2013 edition of Sport Aerobatics ("Flight Level 220 in a Pitts"), the rest is literally history now!
In early 2013 while waiting for delivery of the electronic ignition that was still a few months away I turned my efforts towards increasing the spin rate by tuning weight and balance. Leaning heavily on my Drift Innovation HD video cameras I documented spin rates at various altitudes when flying alone and with a passenger in the front seat.
Anyone who has ever calculated the W&B of a Pitts S-2B or S-2C with a normal size adult passenger in the front seat understands the unspoken truth about flight training in a Pitts and as it turns out the spin rates are faster with both seats occupied due to aft CG but that is also a lot of extra weight to try and drag up to altitude and frankly I'm not sure anyone else wants to go along for THAT ride. After a fair amount of experimentation I figured out how to get the CG location to the aft edge of the envelope with minimal increase in weight and without sacrificing safety when it comes time to recover from the maneuver in the accustomed manner.
Once the W&B problem was solved I did a series of test flights in small blocks of altitude from very low to as high as practical in order to measure spin rates per 1000' and build a spreadsheet model that could be used to predict through extrapolation the anticipated performance up to 23,000' and make a go/no-go decision about another attempt at the record.
My spreadsheet told me that if I could get to FL230 and make a clean entry with a crisp recovery at 2000' that 83 turns would occur. Given that 81.75 turns were recorded my calculations were only off by 1.5%.
In the middle of September 2013 I contacted my friends at NAF El Centro and asked about the possibility of using their air space in November to make attempt #2. The mission of this Naval air facility is to accommodate fighter jets and attack helicopters for training activities on their bomb ranges and of course host the Blue Angels winter training so everyone there is spring loaded to say yes because this place is a "hotel" for aircraft and hospitality is everything. Helicopter squadrons from the USMC, British, and Danish forces come to El Centro to train in brownout conditions caused by the native desert sand.
My last attempt at breaking this record in 2011 was the same week as the annual air show so all of the accommodations are already in place for civilians and their aircraft to be on base. After making my request to the base commanding officer it was approved for early December and I would have to arrange for my own fuel since avgas is nowhere to be found on a military base.
On a side note, the only reason that the Navy let me land on their normally closed to the public airfield and use their restricted air space is because over the years that I have flown in their air show it was demonstrated that my level of preparation, airmanship and safety consciousness is becoming of an air show professional.
As I coordinated my flight for December 8, 2013 the plan called for me to depart Camarillo airport on Saturday December 7th and first land at Imperial County Airport for fuel then make the final 5.5 mile leg to NAF El Centro, spend the night on base with my support crew and the official Judges along with the president of Electroair who all drove there on Saturday and make my attempt at 9:00am Sunday.
As often happens in GA the weather is the biggest factor in diverting the best laid plans and I wasn't able to depart Camarillo airport on Saturday due to a severe wind event in El Centro. Everyone was there but me and my airplane. Plan "B" went into effect and I departed Camarillo at sunrise on Sunday which only delayed my record attempt flight in El Centro by a few hours.
After landing and reviewing the video only 77 turns were accomplished and given that the record was 78 it was astonishing that I could have such a near miss. During the flight I accidently pulled the throttle part way off the wide open stop while making a mixture adjustment and didn't notice the change in noise levels because my ears were clogged from the rapid pressure change. I spun for nearly 4000' at half throttle which cost me the record that day. Upon close study of the videos, there were other mistakes made as well which were taken as lessons learned for the next attempt.
At this point there was no doubt in my mind that the plane could break the record IF the pilot doesn't prevent it from doing so.
With my tail between my legs and my ego crushed I sheepishly went to the commanding officer and public affairs officer of the base and thanked them for their support and asked for 1 more chance right before the air show in March, which I was already confirmed to perform in. Without even blinking they said yes and I ended the year on an uptick.
I figured that my third attempt to break this record in El Centro would probably be my last because after a while your credibility wears pretty thin when you don't do what you say and I really felt like I owed them a world record for all they have done for me over the years. I spent the next several months making sure that everything was dialed in: I practiced entering the maneuver with enhanced in-spin aileron to assure that all flight controls are engaged especially in the high altitude and practiced crisp recoveries with an easy low G pull. I spent more time riding my bike and doing squats to build leg strength to keep that right rudder all the way in for 3 minutes. I serviced the oxygen mask, tank and regulator to make sure they were all in perfect working condition and ran multiple tests on all 3 cameras letting them record until the batteries ran out of juice to assure that 3 hours of video could be captured which is the expected length of a battery charge. The Garmin Foretrex 401 GPS with barometric altimeter to record descent rates and get me right over my "SPIN" waypoint was checked on every practice flight, if any piece of equipment needed to fly safely or document the event wasn't up to the task it was going to be replaced.
For this flight El Centro had reserved restricted area R2510A which only goes up to 15,000' for air show week so I had to coordinate ahead of time with LA Center for clearance into the class A above that. Working with LA Center was the easiest part of this process since I already knew the ins and outs of taking a VFR airplane into class A airspace and all of the same people were there since my last attempt.
I arrived in El Centro on Wednesday March 12, 2013 and prepared the plane for a 9:00am departure on Thursday morning. When the sun rose so did multiple cloud layers over the area so that delayed my takeoff for nearly 2 hours while waiting for it to clear. As every GA pilot knows there is nothing more frustrating than waiting for weather to clear for a flight that you HAVE to make. It was worth the wait because anything that could obscure the vision of the cameras and cast doubt on what needed to be documented would have ruined the day.
 In a reciprocating engine, top dead center of piston #1 is the datum point from which ignition system measurements are made and the firing order is determined. For example, ignition timing is normally specified as degrees before top dead center (BTDC).


The appointment of Satya Nadella as the chief executive officer of Microsoft Corp is yet another recognition of Indian talent in technology and business.
He was actually being considered for the top executive position of the iconic software company along with another Indian, Sundar Pichai of Google. The fact that Nadella had his basic technology education from a university in Karnataka will also bring cheer to many. It is not the first time that Indians have reached top technological or managerial positions in ranking international companies. There are others like Indra Nooyi of Pepsico and Anshu Jain of Deutsche Bank who have made a mark as leaders. Many Indians have proved themselves as experts with remarkable domain knowledge of the areas where they work. But it is not specialised knowledge that propels people to top positions. It is a combination of knowledge, leadership power, innovative skills, personal qualities and interpersonal and communication abilities that makes a top leader. It should be a matter of pride for the country that it has many men and women who meet the most stringent leadership standards of the world.
Though Microsoft is an iconic company, it has lost its edge in many areas and it is for Nadella to give it a new direction and restore its prime status. It still dominates the personal computer market but the arrival of new devices like the smart phone and the tablet has posed a challenge. It is in competition with some of the best technology companies like Apple and Google. Its acquisition of Nokia has given it hardware openings which have to be explored further. A revival of the company will call for tough decisions at the technological and strategy levels.
Nadella is an insider, having been a part of the company for over two decades. He has run its cutting edge cloud computing division and knows its strengths and weaknesses. He may not have the unclouded vision of an outsider who can take an objective look at a company that needs to change. But the fact that the company has chosen him as its future leader after a long search underlines its faith in his abilities. Many start-ups and garage enterprises have grown into corporate giants on the strength of innovative ideas. But to give a fresh momentum to a leader which has stalled on the way and turn it around is much more difficult. That is the test and challenge for Nadella.


Decorator that marks a class field as an input property and supplies configuration metadata. Declares a data-bound input property, which Angular automatically updates during change detection.
You can supply an optional name to use in templates when the component is instantiated, that maps to the name of the bound property. By default, the original name of the bound property is used for input binding.
The following example creates a component with two input properties, one of which is given a special binding name.

Integrated Watershed-Scale Response to Climate Change in Selected Basins across the United States
https://doi.org/10.1175/2011EI376.1
Understanding the effects of climate change on the vegetative growing season is key to quantifying future hydrologic water budget conditions. The U.S. Geological Survey modeled changes in future growing season length at 14 basins across 11 states. Simulations for each basin were generated using five general circulation models with three emission scenarios as inputs to the Precipitation-Runoff Modeling System (PRMS). PRMS is a deterministic, distributed-parameter, watershed model developed to simulate the effects of various combinations of precipitation, climate, and land use on watershed response. PRMS was modified to include a growing season calculation in this study. The growing season was examined for trends in the total length (annual), as well as changes in the timing of onset (spring) and the end (fall) of the growing season. The results showed an increase in the annual growing season length in all 14 basins, averaging 27–47 days for the three emission scenarios. The change in the spring and fall growing season onset and end varied across the 14 basins, with larger increases in the total length of the growing season occurring in the mountainous regions and smaller increases occurring in the Midwest, Northeast, and Southeast regions. The Clear Creek basin, 1 of the 14 basins in this study, was evaluated to examine the growing season length determined by emission scenario, as compared to a growing season length fixed baseline condition. The Clear Creek basin showed substantial variation in hydrologic responses, including streamflow, as a result of growing season length determined by emission scenario.

Climate simulations by the Intergovernmental Panel on Climate Change (IPCC) have demonstrated warming of the surface of Earth from 1860 to 2000 (Houghton et al. 2001). The simulated climatic changes show a significant impact on growing season length (GSL) leading to corresponding changes to important hydrologic cycles in the watershed-scale hydrologic cycle.
GSL, the onset of spring warming, the delay in fall cooling, and basin hydrology are integrally linked. GSL has been shown to affect hydrologic factors such as snowmelt and runoff (Backlund et al. 2008). In areas of the western United States, a shift in the onset of snow and the timing of snowmelt can affect water availability related to drinking water, hydroelectric power, and fish reproduction (Barnett et al. 2005). In addition, a change in the GSL can alter the hydrologic cycle by increasing evapotranspiration, depleting soil moisture, and reducing streamflow (Backlund et al. 2008). Along with hydrologic effects, the GSL is traditionally associated with crop production and impacts on crop yields. For any agricultural commodity, variation in yield between years is related to the growing season weather (Backlund et al. 2008). Such a change in GSL could translate to a corresponding change in water usage, that is, an increase in usage due to a longer growing season or a decrease due to a shorter period for crops to reach maturity (Backlund et al. 2008).
As with agriculture, GSL affects forested areas. Forest growth appears to be increasing in regions of the United States where tree growth is normally limited by low temperatures and short growing seasons (McKenzie et al. 2001; Joos et al. 2002; Caspersen et al. 2000). In the semiarid forests of the southwest, however, forest growth has been decreasing because of drought effects and longer warm periods (McKenzie et al. 2001; Joos et al. 2002; Caspersen et al. 2000). Some forest types within the United States such as oak/hickory are projected to expand, and others such as maple/beech/birch are predicted to contract. The spruce/fir is likely to disappear altogether with increasing temperatures (Ryan et al. 2008; Fagre et al. 2009).
A change in the GSL can also dramatically influence biologic territories and life cycles (Logan et al. 2003). Increasing GSL has been related to changes in migratory bird patterns, increased insect infestation, and changes in habitat (Janetos et al. 2008). A study of bird migration has documented that birds wintering in the southern United States now arrive back in the Northeast an average of 13 days earlier than they did between 1900 and 1950, and birds wintering in South America arrive back in the Northeast an average of 4 days earlier (Janetos et al. 2008). Phenological studies have shown that the increase in GSL caused by warmer air temperatures have caused many species of animals and plants to expand their geographic ranges poleward in latitude and upward in elevation over the past century (Haggerty and Mazer 2008). In an analysis of 866 peer-reviewed papers exploring the ecological consequences of climate change, nearly 60% of the 1598 species studied exhibited shifts in their distributions and/or phenologies over the 20- and 140-yr time frames (Parmesan and Yohe 2003). For example, the pine beetle has expanded its range into regions previously too cold to support its survival because of increases in temperatures and growing seasons (Carroll et al. 2003). These biological shifts in spatial and temporal range are being called the "fingerprint of climate change" (Haggerty and Mazer 2008). There are many aspects of the ecosystem the GSL can affect across the United States and the world.
This paper focuses on the potential impacts that climate change can have on GSL and the hydrologic cycles of 14 selected basins across the United States. The basins are shown in Figure 1 and listed by drainage area in Table 1. General circulation models (GCMs) are used to determine emission scenarios as input into the Precipitation-Runoff Modeling System (PRMS).

Selected basins listed by drainage area.
Numerous studies quantifying GSL have been completed in the United States. The studies examine GSL using a variety of methods such as statistical methods, phenological events, and climatological indicators. The U.S. Department of Agriculture's National Agricultural Statistics Service defines the GSL as the time between the last and first freezing air temperatures. The first and last freezing temperatures have been used in many studies (Wang 1963; Brinkman 1979; Cooter and LeDuc 1995; Kunkel et al. 2004). The GSL can also be defined as the period between the last hard frost in the spring and the first hard frost in the fall. Hard frost is defined as daily minimum temperature necessary to kill 50% of exposed plants (Baron et al. 1984). GSL has also been defined as the period between the last killing frost in the spring and the first killing frost in the fall (U.S. Army Corps of Engineers 1987). A killing frost is a temperature of 28°F or colder. The PRMS model in this study incorporates using the period between the last killing frost in the spring and the first killing frost in the fall as the method for determining the GSL for each year.
The U.S. Geological Survey modeled the hydrologic conditions from 2001 to 2099 in 14 basins across the United States using the PRMS model (Figure 1). These 14 basins have a current or past PRMS model application developed for a variety of reasons (Table 1). Results from global climate models (GCMs) were used in the PRMS model as input data for future conditions. However, the GCM spatial resolution is too coarse for hydrologic modeling at the same scale as the basin models, so GCM precipitation and temperature output were downscaled from a coarse resolution to a finer resolution required by the PRMS models.
A brief description of the development of future conditions and model processing is given here, and a detailed description of the methods is provided elsewhere (Hay et al. 2011). Because of the uncertainty in climate modeling, it is desirable to use more than one GCM in order to obtain a range of potential future climatic conditions. Monthly precipitation and temperature output data from five GCMs were processed and used to calculate the climate fields for the PRMS model (Table 2). For each GCM, one current baseline scenario and three future emission scenarios were used (Table 3). The three future emission scenarios (Table 3) lead to very different patterns in greenhouse gas emissions and concentrations (Alley et al. 2007). The GCM output was obtained from the World Climate Research Programme's Coupled Model Intercomparison Project phase 3 (CMIP3) multimodel dataset archive (Alley et al. 2007).
GCM outputs used in this study from the World Climate Research Programme's CMIP3 multimodel dataset archive. GCM definitions not expanded in the text: Bjerknes Centre for Climate Research Bergen Climate Model (BCC-BCM2.0), Commonwealth Scientific and Industrial Research Organisation Mark version 3.0 (CSIRO Mk3.0), Institute of Numerical Mathematics Coupled Model version 3.0 (INM-CM3.0), and Model for Interdisciplinary Research on Climate 3.2 (MIROC3.2).
General Circulation Model baseline and future emission scenarios chosen for this study (from Alley et al. 2007).
Climate variables used in the PRMS model were derived by calculating the change in climate from baseline to future conditions simulated by each GCM. The 20C3M baseline scenario for water years 1988–99 (a water year is defined as 1 October of a given year to 30 September of the following year, designated by the year in which it ends) was used to represent baseline climatic conditions (Alley et al. 2007). This 12-yr period of record was selected based on the overlap of the available historic records from the 14 basins included in the national study (Hay et al. 2010). Mean monthly climate variables (percentage change in precipitation and degree changes in air temperature) were computed for 12-yr moving window periods (2001–99) using the 20C3M (1988–99) and the A2, B1, and A1B scenarios (Table 3). A 12-yr moving window, starting in 2001 and ending in 2099, results in 1320 future scenarios [(eighty-eight 12-yr climatologies: one per year starting with 2001–12 and ending with 2088–99) × (3 GCM scenarios) × (5 GCMs)]. A schematic of this process is detailed in Figure 2. Climate variables for PRMS were generated by modifying the daily PRMS precipitation and air temperature inputs (1988–99) with the mean monthly climate variables derived from the GCMs, resulting in 1320 future scenarios for each study area. The first year of each 12-yr simulation was used as PRMS initialization and was not included in the results analysis.
The PRMS model was modified to simulate climate change impacts on GSL. The PRMS model runs in a preprocessing mode to determine the day of the last spring frost and the day of the first fall frost for each year, by hydrologic response unit (HRU) for the period of record of the climate data. The seasonal start and end frost dates are averaged together to create spring and fall frost parameters by HRU in PRMS. The preprocess mode in PRMS calculates basin average spring and fall frost parameters in addition to the HRU parameters. The GSL parameters are appended to the main PRMS parameter file. Standard PRMS simulations use the spring and fall frost parameters to determine when to compute transpiration. During periods of active transpiration, both transpiration and evaporation are calculated in PRMS. If transpiration is inactive, then PRMS only calculates evaporation.
The change in annual GSL (number of days) for each emission scenario and basin is shown in Table 4. All of the basins under all three emission scenarios exhibited an increase in GSL. The largest increases in GSL generally occurred in the three mountainous regions: the Cascades, Sierra Nevada, and the Rockies. The mountainous regions GSL varied from 24 to 76 days for all three scenarios. The Midwest and Southeast regions had the lowest increases in GSL overall (14–39 days), whereas the increases in GSL in the Northeast were between the two extremes (20–43 days). The mean increase in GSL for all basins for the three future emission scenarios was from 27 to 47 days. The 14 basins not only showed an increase in total GSL but also showed a change in the onset and end of the growing season (Table 5). The mountainous basins demonstrate the largest shifts in either the onset or the end of the growing season, whereas the Midwest, Northeast, and Southeast basins exhibit a smaller shift in the timing of the growing season. All basins show an earlier onset of spring and delay in the first fall killing frost.
Modeled growing season length increase in days from 2001 to 2099. Values represent average of five GCMs for the three emission scenarios by basin.
Projected change in the beginning and ending of the growing season from 2001 to 2099.
Figure 3 shows the change in mean GSL of all basins for each emission scenario through time. The solid colored lines represent the mean value for each of the emission scenarios with the associated color cross-hatch representing the uncertainty associated with the prediction. In general, the results show the model predictions for these selected basins vary largely because of uncertainties in the climate predictions, with the uncertainty increasing as the simulations approach the end of the century (Figure 3).
The projected effects of an increasing GSL on the 14 selected basins are substantial. Table 6 shows the projected change in a number of hydrologically important characteristics by year (slope) and adjusted R2 (adjR2) based on the central tendencies of the five GCMs for each of the three emission scenarios. The subtables show, by variable, changes in slope of the central tendency; the table values set in bold indicate a significant positive trend (p < 0.05) and the values set in italics indicates a significant negative trend (p < 0.05) for all 14 basins. The adjusted R2 value gives an indication of the variability around the trend line, with higher adjusted R2 values having smaller variability. Table 6a shows the GSL statistically has a significant positive trend and low variability. The increasing warming and drying could lead to potential increases in GSL; Table 6b shows that there is a significant positive trend in precipitation in the A1B emission scenario but little positive to negative trends in both the A2 and B1 emission scenarios with higher variability for all three emission scenarios. The majority of basins under all three emission scenarios exhibited higher minimum and maximum temperatures and evapotranspiration, with decreases in soil moisture and decreased streamflow (Tables 6c–g). These factors and an increasing GSL could lead to variations in water availability, which would have a direct impact on agricultural production and water supply in the study basins. An increase in temperature has the potential to impact agricultural production due to the northern migration of competing plants and an increase in insects that is expected to accompany the forecast climate changes (Janetos et al. 2008). In the fire-prone areas of the Rockies and Sierra Nevada study basins, an increase in GSL can cause an increase in tree mortality, which can increase the fuel sources for potential wildfires (Ryan et al. 2008; Fagre et al. 2009). The increase in GSL could increase the amount of water needed for plant growth; Table 6b shows that the model results do not indicate large increases in precipitation for the 14 basins coupled with the predicted small increases in precipitation; and the probability of drought conditions over a longer GSL is increased.
Projected change by year (slope) and adjR2 based on the central tendencies of the five GCMs for the three emission scenarios by basin: (a) growing season, (b) precipitation, (c) minimum temperature, (d) maximum temperature, (e) evapotranspiration, (f) soil moisture, and (g) streamflow. Italics indicate a significant negative trend, and bold indicates a significant positive trend (p < 0.05).
The PRMS model was modified to examine the effects of emission scenarios on the total GSL, as well as the effects on the beginning and end of the GSL periods. Another factor evaluated was the impact of the modified GSL computations on hydrologic flows simulated by the PRMS model. The Clear Creek basin PRMS model was selected to examine the modified GSL results and compare to a GSL fixed baseline condition. Table 7 shows which variables changed when the emission scenario determined by GSL was included in the PRMS simulation. The results show there is a change in evapotranspiration and in a majority of the flow variables. Slopes increase in the same positive or negative directions when GSL determined by emission scenario is included in the PRMS simulation. In addition, the adjusted R2, which indicates a smaller variability and increased accuracy of the model, also increases with the inclusion of the emission scenario determined GSL. These results show that the GSL in the PRMS model has an effect on the results of the hydrologic cycle of the Clear Creek basin.
Projected change by year (slope) and adjR2 based on the central tendencies of the five GCMs for the three emission scenarios for the Clear Creek basin, showing the difference between GSL fixed to baseline conditions and GSL determined by emission scenario.
The future growing season length at 14 basins across 11 states were modeled using five general circulation models with three emission scenarios as inputs to the PRMS. The GSL increased in all three climate change emission scenarios though the twenty-first century. The 14 selected basins in the United States have shown an overall increase in GSL ranging from 14 to 76 days by 2099, depending on the emission scenario. The modeled GSLs are positively correlated with forecasted increases in temperature. All climate change emission scenarios evaluated with PRMS showed an increase in temperature through the twenty-first century. The uncertainties and ranges in the increasing temperatures are reflected in the uncertainty and range in the GSL results.
GSL values for Clear Creek basin, 1 of the 14 basins in this study, were calculated for each emission scenario and compared with a (fixed) baseline GSL. As Table 7 shows, there are increasing changes in both flow and evapotranspiration when GSL is compared with the baseline condition.
Changing land cover could impact the GSL of the 14 basins, potentially influencing both temperature and resultant flows. It should be understood that neither the PRMS model nor the GCMs currently account for land-cover change.
The results in this paper represent a method for calculating GSL as a function of climate change emission scenarios. The results show there is a future need to improve PRMS/GCM modeling by including a changing land use/land cover, because this important factor for determining GSL is not represented in this study. This study has shown that GSL does have hydrologic impacts that should be examined in more detail. The increases in GSL that will accompany forecasted increases in temperature are important because they are integrally linked with a range of factors such as phenological events, agricultural production and practices, and water resources across the United States.

Letting an Opponent Control Play is Risky.
They have an article in the new issue, Table Tennis Remains Diversity's Best Kept Secret. (I think it's in the December print issue.) The story features one of my students, Navin Kumar, as well as Nancy Zhou, Dr. Tsz Lun (Alan) Chu, Ibrahim Hamadtou, Anushka Oak, and Lily Zhang. Navin's involvement (and I think some of the others) came about when the writer contacted me with a series of questions about diversity in table tennis. I thought about it for a few days, and realized I was probably not the right person to interview about this. To use a metaphor, cars are important, but I'm probably not the person to interview about cars. (What's a carburetor? I have no idea.) So I sent them some other contacts, and then turned them over to Navin, who is Indian, as well as having Parkinson's (bronze in singles, silver in doubles at the 2019 World Parkinson's Table Tennis Championships) as well as having a mostly artificial heart.
Why Doesn't Table Tennis Get More Exposure?
I was asked on Facebook recently (by Mike Clardy) why our sport gets so little TV (and online) exposure from the major venues, while sports like bowling, darts, and even axe throwing get more coverage. Here was my response (with some minor updating).
It's always been a strange phenomenon that table tennis gets so little TV exposure in the US, while more obscure sports (and in some cases, "sports") are on TV. There have been a few isolated cases, such as ESPN's coverage of table tennis circa 1980, and we had some TV exposure in the early 1990s due to Dan Seemiller's efforts. But these are the exceptions. In general, table tennis doesn't get nearly as much TV exposure as other, seemingly lesser sports. The same thing applies to the various major online venues as well. But long ago I realized why. I'm going to explain with a seemingly non-related item - the history of Star Trek.
In 1964, Gene Roddenberry went to Desilu Productions with the idea for Star Trek. It was well-thought out, but was so revolutionary that it was turned down by CBS and NBC. The board of Desilu also voted against producing it - but they were overruled by their owner, Lucille Ball, of "I Love Lucy" fame. Ball liked the idea and championed it, and made Star Trek happen. If not for her, there would be no Star Trek. (Here's an article about it from Entertainment Weekly and here's another from Star Trek.com.)
How does this relate to table tennis? Well, look at all those sports and "sports" that get exposure on TV. Also look at all the bad movies and TV shows that get made. Why does that happen? Because of each of them had a "champion" who made it happen. It means that no matter what you do, there is an element of luck in getting something produced on TV.
However - and this is the BIG HOWEVER - there's a saying in sports that champions make their own luck. What that means when it comes to getting on TV is two-fold. (And now I'm going to cleverly and completely change the meaning of the word "champion.") First, you have to find your champion. Second, you have to sell your champion. In the case of Star Trek, Roddenberry went to multiple networks and studios in search of a champion, and found one in Lucille Ball. Then he was able to sell her on the idea. She championed its production, and the result is history.
In the case of all those bad movies, TV shows, and "sports" that get more TV and online coverage in the US than table tennis, they all did the same thing - they looked for and sold themselves to a champion, and that champion made it happen.
What does this mean for table tennis in the US? Occasionally someone from USATT or elsewhere looks for a champion, but is unable to sell it. Others might be able to sell it, but aren't looking for that champion, or don't know how to do so. More often, neither happens. And so (with rare, temporary exceptions), we have never found and sold ourselves to a champion to get table tennis regularly on TV in the US.
How can we change this? Simple, and by that, I mean the idea is simple, but the execution not so easy. It means going to those people (like Lucille ball) who are in a position to put both good and bad movies, TV shows, sports, and "sports" on TV and large online venues, and selling them on table tennis, just as Roddenberry did with Star Trek. It's how all those good and bad productions got on TV. All we have to do is to follow in their footsteps, and keep doing so until we find our champion - i.e. we MAKE our luck. (Hopefully as a sport, not a "sport.") If all goes well, someday someone will point at us and say, "How come a 'sport' like table tennis gets so much TV exposure, while our sport doesn't?"
One addendum I'd add to the above is that when we do get coverage, we need to make it stand out (duh!). Many focus on the personalities, which is important. But equally important, and maybe even more so, is to focus on conflicting styles. One of the reasons people love to watch Federer vs. Nadal in tennis is that clash of styles - the elegant Federer, with his power forehand and one-handed backhand, vs. the runs-down-everywhere Nadal with his topspinning forehand and two-handed backhand. One of the reasons the current world #1, Novak Djokovic, is considered boring is that he doesn't really bring anything exciting, style-wise - he's basically a robotic backboard who never misses. The same is true of the past tennis - think of the clash in styles of McEnroe (net-rusher) vs Borg (two-winged topspinner) v. Connors (aggressive flat hitter). Or boxing - who could forget the dancing, boxing style of Muhammed Ali vs. the constantly coming-at-you attack of Joe Frazier? (Okay, I'm dating myself.)
In the past, table tennis at the top had more styles, but many of those styles are almost dead now - pips-out hitters, choppers, even Seemiller grip players. The difference in styles is more subtle, so it's more important that the commentators and public relations directors emphasize the differences - for example, the backhand dominance of Japan's Tomokazu Harimoto vs. the off-table topspins of Xu Xin vs. the two-winged blistering attacks of Ma Long and Fan Zhendong.
Weekend Coaching and MDTTC Juniors
On Sunday, I worked mostly with two of the younger players in the junior session, with a focus (as usual) on fundamentals. One thing that always surprises me about younger kids - they are fascinated with serves, and given a choice, will often choose to do that (and do ball pickup!) rather than actually, you know, play!!! Afterwards, I stayed late and hit with two of our 1800 juniors. I'm way, Way, WAY out of shape after eight months of pandemic isolation (i.e. mostly sitting in my lounge chair reading, writing, doing crossword puzzles, and watching TV), and when I played a practice match with one of them, it showed.
This was the first Friday-Sunday after Thanksgiving since 1975 that I didn't play or coach at the North American Table Tennis Teams Championships (previously the US Teams). My first year was 1976, when I was 16, and it's been 44 years in a row until now. It was cancelled this year.
All these cancelled tournaments is, of course, disappointing to the kids, who train so hard for them, as well as the incredible coaching staff that works with them. I'm pretty proud of our players. In the new rankings that came out last week (after the Presper Financial Architects Open in Ohio, which didn't get cancelled), in Hopes Boys (12 and under), my club (MDTTC) now has the #1, 3, 5, and 6 players in the country, with ratings of 2286, 2078, 2020, and 1994. We also have the #2 and #3 in 11 and under, at 2078 and 1994 - these two are also in the Hopes rankings at #3 and # 6, and have another year of eligibility. We also have the #1 in 9 and under. (The latter plays out of Philadelphia but trains with us on weekends.) We also have 7 of the 21 players in Mini-Cadet Boys (13 and under). Along with my great fellow coaches, I've worked extensively with most of these players, several of them starting out with me. Here's a listing of some of our top junior players.
Stanley Hsu (12, 2286, #1 in Hopes Boys, National Hopes Champion)
Tiffany Ke (16, 2220, #12 in Junior Girls, but recently #1 with a rating over 2400, with two years of eligibility left, National Team Squad)
Nicole Deng (14, 2116, National Mini-Cadet Champion, National Team Squad, trains with us on weekends)
Ryan Lin (11, 2078, #3 in Hopes Boys, #2 in 11 and Under)
William Wu (14, 2071)
James Zhang (13, 2059, #14 in mini-cadets)
Stephanie Zhang (17, 2038)
Lance Wei (13, 2027, #17 in mini-cadets)
Mu Du (12, 2020, #5 in Hopes Boys)
Winston Wu (11, 1994, #6 in Hopes Boys, #3 in 11 and Under)
Ryan Lee (13, 1986, #21 in mini-cadets)
Arjun Kumar (9, 1585, #1 in 9 and Under, trains with us on weekends)
A dozen others from 1600-1900
On Saturday, I had my weekly session with Navin Kumar. (As I've often noted, I'm retired from private coaching except for these sessions.) He made a breakthrough on attacking pushes with his long pips (no sponge), as he's gaining confidence in taking the ball right off the bounce and "bumping" it with a quick topspin. His forehand was also much stronger than usual this session. Here's video (14 sec).

USATT Coaches Meeting
The Zoom meeting was on Friday, Nov. 27, at 11AM. Here's video of the meeting (83 min), hosted by Sean O'Neill. The meetings usually take place the second and fourth Friday of each month, and usually last about an hour - and ALL USATT coaches are invited to attend to ask questions and give their thoughts. (Info on each meeting is posted in advance in the USATT Coaches Facebook page.) Discussions included Coaches feedback on their latest activities; Coach of the Year award; SafeSport/Background Checks; Articles for the USATT website; National Development Team; World Table Tennis Feedback; and perhaps of most interest to viewers, a great discussion of coaching between games that starts at 16:56 where all five of us give our thoughts on this. There were five of us attending:
USATT High Performance Director and five-time US Men's Singles Champion Sean O'Neill
USATT High Performance Manager and long-time USA Women's Team Coach Doru Gheorghe
USA National Team Coach and 8-time US Women's Singles Champion and former world #3) Gao Jun
USATT Certified National Coach and 2018 USATT Volunteer Coach of the Year Mike Lauro
Champion and Great Entertainer, Jacques Secretin passes (1949-2020)
Here's the ITTF obit. He was a big star in the 1970s and 80s, reaching #3 in the world, 1976 European Men's Singles Champion, 1977 World Mixed Doubles Champion (along with four silver medals), and completely dominating French table tennis for decades. (Here's his Wikipedia page.) Besides his lefty topspin attacking, he was also known for his lobbing - when I started out in 1976, I was told he was one of the "Big Three Lobbers" - Secretin, Surbek, and Hasegawa. However, he was best known as half of the famous "Secretin-Purkart" exhibition team - he was the brilliant and incredibly skillful straight man to Vincent Purkart's clowning. Here's video from their exhibitions (8:20). Here's another article, Jacques Secrétin, the legend of table tennis, is dead, from World Today News, with more pictures and great video.
PongNow: Ty Hoff
Here's the video (20:17) by Steve Hopkins. Ty and I have a long history. I was one of his original coaches. His first coaching came at the 1980 Perry Schwartzberg Camp in Wilson, NC, where I was Perry's assistant coach. Later, Ty hired me as a private coach for I think three days in New Bern, NC. Still later, Ty and I teamed up to nine US Open and Nationals Hardbat Doubles titles. (I also won singles twice, while he won I think four times. I normally use sponge.) We also made the quarterfinals of Men's Doubles at the Nationals one year. In 1990, when I became the director of the Resident Table Tennis Program at the Olympic Training Center in Colorado Springs, I brought in Ty as the dorm manager, where he also acted as a practice partner.

Non-Table Tennis - "The Untold Christmas Carol" and "Pinning the Egg"
Tangent, one of the big science fiction reviewers, did a very positive review of a current story of mine in Galaxy's Edge, "The Untold Christmas Carol," the behind-the-scenes expose of what really happened to Tiny Tim - with Satan and Benedict Arnold involved. The review finished with this: "The prose was well-paced and told in a whimsical style. A nice nugget to pass a few minutes with a smile." Here's the review. On Wednesday, I sold a humorous science fiction story to the Sci-Fi Journal, "Pinning the Egg." (It involves an alien invader and Excalibur, but in a SF fashion.)


Luton Council of Mosques (LCM) and Luton Sunni Council of Mosques (SCM) are organising a hustings event – this is a forum for the public to hear how their political candidates plan to represent the local community and, in particular, recognise the needs of the Muslim community. The event will include a panel of candidates with representation from across the political spectrum and Luton's wards.
The event will provide a short introductory statement from each candidate followed by an open Q & A session with the audience.
