2017 Myanmar Air Force Shaanxi Y-8 crash. On 7 June 2017, a Shaanxi Y-8 aircraft of the Myanmar Air Force crashed on a flight from Myeik to Yangon, killing all 122 people on board. Debris from the aircraft was found in the Andaman Sea, 118 nautical miles (218 km) off Dawei by Myanmar Navy ships. It is the deadliest aviation accident in Myanmar's history.

History of the flight 

The aircraft had departed from Myeik for Yangon at 13:06 local time (06:36 UTC). At 13:35, communication was lost with the aircraft when it was  west of Dawei. The aircraft was flying at  at the time. A search and rescue operation was launched in the Andaman Sea. An unidentified spokesman said that weather was not thought to be a factor in the aircraft's disappearance. No mayday call had been received from the aircraft.

Aircraft 

The  aircraft involved was a Shaanxi Y-8F-200 of the Myanmar Air Force, serial number 5820. It had been delivered in March 2016 and had flown for over 800 hours at the time of the crash.

Passengers and crew 

The aircraft's captain was Lt-Col Nyein Chan and the co-pilots were Lt-Col Soe Thu Win and Maj Thant Zin Htay. The aircraft had 14 crew members.

108 military staff members and their families, including 15 children, were on board when the plane lost communication with Dawei airbase. Six officers and 29 other military personnel were on board.

Search 

Nine Myanmar Navy ships, and three military aircraft and helicopters were sent to assist in the search. On 7 June, debris from the aircraft was reported to have been found  off Dawei by a Myanmar Navy ship. On 8 June, it was reported that 29 bodies had been found.

The wreckage was scattered over a wide area, indicating that the aircraft might have disintegrated in flight at altitude. Storms in the area hindered the search. By 9 June, hopes of finding survivors were fading. It was later reported that there were no survivors. Instead, bodies and debris have been found scattered in the Andaman Sea, and some washed ashore.

This was the deadliest aviation accident to occur in Myanmar, surpassing the crash of a Fokker F27 Friendship 500 in 1987, which killed 49 people.

On 15 June, a fishing boat helping with the search found the tail of the aircraft off Myinkhwar Aww Bay. The cockpit voice recorder and flight data recorder were recovered on 18 June.

Investigation 

Investigator determined that control of the aircraft was lost after it entered thick storm clouds and encountered icing conditions.

Zeldovich mechanism. Zel'dovich mechanism is a chemical mechanism that describes the oxidation of nitrogen and NOx formation, first proposed by the Russian physicist Yakov Borisovich Zel'dovich in 1946. The reaction mechanisms read as

{N2} + O <->[k_1] {NO} + {N}
{N} + O2 <->[k_2] {NO} + {O}

where  and  are the reaction rate constants in Arrhenius law. The overall global reaction is given by

 {N2} + {O2} <->[k] 2NO

The overall reaction rate is mostly governed by the first reaction (i.e., rate-determining reaction), since the second reaction is much faster than the first reaction and occurs immediately following the first reaction. At fuel-rich conditions, due to lack of oxygen, reaction 2 becomes weak, hence, a third reaction is included in the mechanism, also known as extended Zel'dovich mechanism (with all three reactions),

{N} + {OH} <->[k_3] {NO} + {H}

Assuming the initial concentration of NO is low and the reverse reactions can therefore be ignored, the forward rate constants of the reactions are given by 

where the pre-exponential factor is measured in units of cm, mol, s and K (these units are incorrect), temperature in kelvins, and the activation energy in cal/mol; R is the universal gas constant.

NO formation
The rate of NO concentration increase is given by

N formation
Similarly, the rate of N concentration increase is

Biosolarization. Biosolarization is an alternative technology to soil fumigation used in agriculture. It is closely related to biofumigation and soil solarization, or the use of solar power to control nematodes, bacteria, fungi and other pests that damage crops. In solarization, the soil is mulched and covered with a tarp to trap solar radiation and heat the soil to a temperature that kills pests. Biosolarization adds the use of organic amendments or compost to the soil before it is covered with plastic, which speeds up the solarization process by decreasing the soil treatment time through increased microbial activity. Research conducted in Spain on the use of biosolarization in strawberry fruit production has shown it to be a sustainable and cost effective option. The practice of biosolarization is being used among small agricultural operations in California. Biosolarization is a growing practice in response to the need for methods for organic soil solarization. The option for more widespread use of biosolarization is being studied by researchers at the Western Center for Agricultural Health and Safety at the University of California at Davis in order to validate the effectiveness of biosolarization in commercial agriculture in California, where it has the potential to greatly reduce the use of conventional fumigants. Biosolarization can also use as organic waste management practice. Recent studies showed the potential  of food industrial residues as soil amendments that can improve the efficiency of biosolarization.

Glow-discharge optical emission spectroscopy. Glow-discharge optical emission spectroscopy (GDOES) is a spectroscopic method for the quantitative analysis of metals and other non-metallic solids. The idea was published and patented in 1968 by Werner Grimm from Hanau, Germany.

Ordinary atomic spectroscopy can be used to determine the surface of a material, but not its layered structure.  In contrast, GDOES gradually ablates the layers of the sample, revealing the deeper structure.

GDOES spectroscopy can be used for the quantitative and qualitative determination of elements and is therefore a method of analytical chemistry.

Process
The metallic samples are used as a cathode in a direct current plasma. From the surface, the sample is removed in layers by sputtering with argon ions. The removed atoms pass into the plasma by diffusion.  Photons are emitted with excited waves and have characteristic wavelengths which are recorded by means of a downstream spectrometer and subsequently quantified.

When using a high-frequency alternating voltage for plasma generation and the corresponding construction of the glow discharge source, non-metallic samples can also be examined.

Various instruments are used as sensors. Photomultipliers can detect the slightest traces and also high concentrations of the sensor-specific element. By means of charge-coupled device, a complete element spectrum can be measured with the appropriate layer thickness.

Applications
Glow discharge spectroscopy is an established method for the characterization of steels and varnishes. Recent developments relate to the analysis of porous electrodes from lithium-ion batteries.

Flirtey. Flirtey (later rebranded SkyDrop) was a Reno, Nevada-based drone delivery company. The company completed the first Federal Aviation Administration (FAA)-approved drone delivery in the United States in 2015, the first FAA-approved urban delivery in March 2016 and the first FAA-approved commercial drone delivery to a customer home in July 2016. Flirtey is also developing air traffic control computer software for drones in a collaboration with NASA. One of the company's drones is in the National Air and Space Museum of the Smithsonian Institution in Washington, D.C.

History 

The company was founded in Australia in 2013 by Matt Sweeny, Ahmed Haider and Tom Bass. The company relocated to the Reno, Nevada area in 2014 after partnering with the University of Nevada, Reno. Flirtey completed the first FAA-approved drone delivery in July 2015, when it delivered medical supplies to a health clinic in Wise, Virginia. In August 2015, Flirtey graduated from the Silicon Valley seed accelerator, Y Combinator. In March 2016, the company flew the first federally sanctioned drone delivery in an urban area without the assistance of a human operator when it carried emergency supplies to a house in Hawthorne, Nevada.

Researchers from Johns Hopkins School of Medicine collaborated with Flirtey to complete the first ship to shore drone delivery in the United States in June 2016. The FAA-approved flight consisted of two parts. First, the drone delivering medical samples flew from land to a barge floating in New Jersey's Delaware Bay. Then, the drone was loaded with medical supplies and delivered its cargo to the Cape May–Lewes Ferry terminal. In July 2016, Flirtey partnered with 7-Eleven to complete its first fully autonomous FAA-approved home delivery to a residence in Reno, Nevada. This was the first time a U.S. customer has been delivered a package by a drone. In January 2017, Flirtey raised $16 million in Series A funding led by Menlo Ventures.

In May 2018, the FAA announced 10 drone programs, including Flirtey, for its Integration Pilot Program that expands permissions to included programs that would typically need specific FAA permits due to airspace regulations. Five of the 10 selected projects involve package delivery. Flirtey is working with four of the winning applicants selected by the program and will use drones as a first response to 911 calls in Reno, Nevada by delivering defibrillators in heart attack cases before an ambulance arrives to allow bystanders to deliver first aid. Flirtey was also included on CNBC's Disrupter 50 list in 2018.

In October 2021, the company announced a partnership with Mesa Air Group involving an order of four drones with an option for 50 more. Mesa plans to use Flirtey Eagle drones to begin conducting food and beverage deliveries.

On 26 February 2024, Sweeney announced on LinkedIn that the company was shutting down.

NanoCLAMP. In the medical field of immunology, nanoCLAMP (CLostridal Antibody Mimetic Proteins) affinity reagents are recombinant 15 kD antibody mimetic proteins selected for tight, selective and gently reversible binding to target molecules. The nanoCLAMP scaffold is based on an IgG-like, thermostable carbohydrate binding module family 32 (CBM32) from a Clostridium perfringens hyaluronidase (Mu toxin). The shape of nanoCLAMPs approximates a cylinder of approximately 4 nm in length and 2.5 nm in diameter, roughly the same size as a nanobody (). nanoCLAMPs to specific targets are generated by varying the amino acid sequences and sometimes the length of three solvent exposed, adjacent loops that connect the beta strands making up the beta-sandwich fold, conferring binding affinity and specificity for the target.

Properties
nanoCLAMPs are the first antibody mimetics described to be polyol-responsive, meaning they release their targets upon exposure to a non-chaotropic salt and a polyol, such as propylene glycol. This property has been shown to be useful for purifying functional proteins and protein complexes by affinity purification. nanoCLAMPs are easily produced in the cytoplasm of E. coli, with typical yields in the range of 50 to 300 mg/L culture. Because nanoCLAMPs are devoid of cysteines, an engineered C-terminal cysteine can be used for site-directed conjugation of entities like fluorophores or resins using thiol-chemistry.

Development and applications
nanoCLAMPs were developed in the laboratories of Nectagen. nanoCLAMP phage display libraries were constructed that contained variations on 16 surface amino acids in three loops with function diversities of approximately 109 variants. These libraries have been screened for binders to target proteins and peptides, typically yielding between 1 and 30 unique binders to the target.

Purified nanoCLAMPs containing a single C-terminal cysteine can be easily conjugated to halo-acetyl activated agarose resins under native or denaturing conditions, and the resulting thioether bond renders the resins leach-proof. Targets can be purified to apparent homogeneity in a single-step. The polyol-responsive nature of the resins allows the targets to be eluted with 0.75 M ammonium sulfate and 40% propylene glycol at pH 7.9, conditions which have been shown to preserve native structure and protein complexes.

nanoCLAMPs have been produced that target green fluorescent protein (GFP), mCherry, SUMO (SMT3), NusA, avidin, NeutrAvidin, maltose-binding protein (MBP), thioredoxin 1, beta-galactosidase, SlyD, and others. Typical binding capacities of resins range from 1 to 4 mg/ml resin. Because nanoCLAMPs readily refold, nanoCLAMP resins can be regenerated multiple times using guanidinium chloride to clean the resin.

Ines R. Triay. Inés Ramona Triay (born January 30,  1958) is the executive director of the Applied Research Center (ARC) and the interim Dean at the College of Engineering at Florida International University (FIU). Triay was appointed by President Obama as the 7th DOE Assistant Secretary for Environmental Management and sworn into office in May 2009. She played leading role at the Office of Environment Management (EM), which is charged with the safe and complete cleanup of the environmental legacy brought about from five decades of nuclear weapons development and government-sponsored nuclear energy research.

Born in Havana, Triay studied chemistry at the University of Miami from 1976 to 1985. She earned a B.S. degree in 1980 and then completed her Ph.D. degree in 1985.

Triay, widely considered an advocate of a strong Hanford environmental cleanup program and a friend to the Tri-Cities, has served as assistant secretary of environmental management for  years.  Triay was responsible for kick-starting the plan for some land at Hanford and other DOE sites to be turned into clean energy parks as environmental cleanup is completed. She stepped down from this position in 2011 because of her father's poor health; however, she continues work with DOE.

It was noted by The Washington Post in June 2017, Obama's nominee, Ines Triay, had been confirmed by the Senate when Obama had moved to fill Energy Department post in his respective administrations where as Trump has filled just 15 percent of the government's top science jobs. On March 29, 2018, Anne Marie White was sworn as Assistant Secretary for Environmental Management at the U.S. Department of Energy. In June 2019, William "Ike" White joined as an acting assistant secretary for the Office of Environmental Management

Resource selection function. Resource selection functions (RSFs) are a class of functions that are used in spatial ecology to assess which habitat characteristics are important to a specific population or species of animal, by assessing a probability of that animal using a certain resource proportional to the availability of that resource in the environment.

Modeling 
Resource Selection Functions require two types of data: location information for the wildlife in question, and data on the resources available across the study area. Resources can include a broad range of environmental and geographical variables, including categorical variables such as land cover type, or continuous variables such as average rainfall over a given time period. A variety of methods are used for modeling RSFs, with logistic regression being commonly used.

RSFs can be fit to data where animal presence is known, but absence is not, such as for species where several individuals within a study area are fitted with a GPS collar, but some individuals may be present without collars.
When this is the case, buffers of various distances are generated around known presence points, with a number of available points generated within each buffer, which represent areas where the animal could have been, but it is unknown whether they actually were.  These models can be fit using binomial generalized linear models or binomial generalized linear mixed models, with the resources, or environmental and geographic data, as explanatory variables.

Scale 
Resource selection functions can be modeled at a variety of spatial scales, depending on the species and the scientific question being studied. (insert one more sentence on scale)

Most RSFs address one of the following scales, which were defined by Douglas Johnson in 1980 and are still used today:
 First order selection: The entire range of a species
 Second order selection: The home range of an individual or group of animals
 Third order selection: Resource or habitat usage within an individual's or group's home range 
 Fourth order selection: The procurement of specific resources, such as food, at specific sites
