Doctors at the government-run ESIC Hospital committed a "mistake" by not testing samples of a 16-year-old girl, who later died of Covid-19, Assam Health Minister Himanta Biswa Sarma said on Saturday.

The news came as the number of daily coronavirus tests fell below the 100,000 target for a seventh day in a row.

The government says "operational issues" in the UK meant 50,000 samples had to be flown to US labs.

Daily coronavirus tests fell the below 100,000 target for a seventh day in a row. Health Secretary Matt Hancock urged Boris Johnson to 'give me a break' in a furious bust-up over the coronavirus crisis.

Doctors at the government-run ESIC Hospital here committed a "mistake" by not testing samples of a 16-year-old girl, who later died of Covid-19, Assam Health Minister Himanta Biswa Sarma said on Saturday. The girl breathed her last on Thursday at the B Barooah Cancer Institute. Her samples, which were taken after her death, tested positive for coronavirus infection/ "The girl first went to ESIC Hospital with all symptoms like fever and pain in legs. It was a mistake by doctors that her samples were not sent for testing... It is a matter of concern," Sarma told reporters here. Talking about the Gauhati Medical College and Hospital (GMCH), which was closed for new patients after a doctor at the facility tested positive on Thursday, he said a total of 529 samples have been collected from doctors, nurses, professors and superintendent of the institute for testing "Out of those, reports of 357 samples came out negative and one was positive. Results of the rest of the samples are awaited," .

Authorities in Jammu and Kashmir carried out nearly 1,000 surprise inspections and lifted 62 samples of different food items for screening since the beginning of this month, an official spokesperson said on Sunday. The special drive by the Food Safety Wing of Food and Drugs Administration Department was necessitated amidst growing concern that some unscrupulous traders can take advantage of the lockdown imposed by the government due to the COVID-19 pandemic, he said. "During the special drive, commenced on May 1, the enforcement staff carried out 996 inspections, lifted 62 samples of different food items like mustard oil, til oil, spices, milk and dates, and destroyed food items, which included vegetables, fruits, milk amounting to Rs 25,000," the spokesperson said. He said four Food Business Operators (FBOs) were also fined for violating the Food Safety and Standards(FSS) Act. The drive also led to seizure of560 kg ghee and 91 kg of spices after lifting statutory samples that have ...

With the continuing development of beamlines for macromolecular crystallography (MX) over the last few years providing ever higher X-ray flux densities, it has become even more important to be aware of the effects of radiation damage on the resulting structures. Nine papers in this issue cover a range of aspects related to the physics and chemistry of the manifestations of this damage, as observed in both MX and small-angle X-ray scattering (SAXS) on crystals, solutions and tissue samples. The reports include measurements of the heating caused by X-ray irradiation in ruby microcrystals, low-dose experiments examining damage rates as a function of incident X-ray energy up to 30 keV on a metallo-enzyme using a CdTe detector of high quantum efficiency as well as a theoretical analysis of the gains predicted in diffraction efficiency using these detectors, a SAXS examination of low-dose radiation exposure effects on the dissociation of a protein complex related to human health, theoretical calculations describing radiation chemistry pathways which aim to explain the specific structural damage widely observed in proteins, investigation of radiation-induced damage effects in a DNA crystal, a case study on a metallo-enzyme where structural movements thought to be mechanism related might actually be radiation-damage-induced changes, and finally a review describing what X-ray radiation-induced cysteine modifications can teach us about protein dynamics and catalysis. These papers, along with some other relevant literature published since the last Journal of Synchrotron Radiation Radiation Damage special issue in 2017, are briefly summarized below.

A new Rococo 2 X-ray fluorescence detector was implemented into the cryogenic sample environment at the Hard X-ray Micro/Nano-Probe beamline P06 at PETRA III, DESY, Hamburg, Germany. A four sensor-field cloverleaf design is optimized for the investigation of planar samples and operates in a backscattering geometry resulting in a large solid angle of up to 1.1 steradian. The detector, coupled with the Xspress 3 pulse processor, enables measurements at high count rates of up to 106 counts per second per sensor. The measured energy resolution of ∼129 eV (Mn Kα at 10000 counts s−1) is only minimally impaired at the highest count rates. The resulting high detection sensitivity allows for an accurate determination of trace element distributions such as in thin frozen hydrated biological specimens. First proof-of-principle measurements using continuous-movement 2D scans of frozen hydrated HeLa cells as a model system are reported to demonstrate the potential of the new detection system.

The fully automatic processing of crystals of macromolecules has presented a unique opportunity to gather information on the samples that is not usually recorded. This has proved invaluable in improving sample-location, characterization and data-collection algorithms. After operating for four years, MASSIF-1 has now processed over 56 000 samples, gathering information at each stage, from the volume of the crystal to the unit-cell dimensions, the space group, the quality of the data collected and the reasoning behind the decisions made in data collection. This provides an unprecedented opportunity to analyse these data together, providing a detailed landscape of macromolecular crystals, intimate details of their contents and, importantly, how the two are related. The data show that mosaic spread is unrelated to the size or shape of crystals and demonstrate experimentally that diffraction intensities scale in proportion to crystal volume and molecular weight. It is also shown that crystal volume scales inversely with molecular weight. The results set the scene for the development of X-ray crystallography in a changing environment for structural biology.

A hitherto unrecognized resolution effect in neutron Larmor diffraction (LD) is reported, resulting from small-angle neutron scattering (SANS) in the sample. Small distortions of the neutron trajectories by SANS give rise to a blurring of the Bragg angles of the order of a few hundredths of a degree, leading to a degradation of the momentum resolution. This effect is negligible for single crystals but may be significant for polycrystalline or powder samples. A procedure is presented to correct the LD data for the parasitic SANS. The latter is accurately determined by the SESANS technique (spin–echo small-angle neutron scattering), which is readily available on Larmor diffractometers. The analysis technique is demonstrated on LD and SESANS data from α-Fe2O3 powder samples. The resulting d-spacing range agrees with experimental data from high-resolution synchrotron radiation powder diffraction on the same sample.

Described here are instructions for building and using an inexpensive automated microscope (AMi) that has been specifically designed for viewing and imaging the contents of multi-well plates. The X, Y, Z translation stage is controlled through dedicated software (AMiGUI) that is being made freely available. Movements are controlled by an Arduino-based board running grbl, and the graphical user interface and image acquisition are controlled via a Raspberry Pi microcomputer running Python. Images can be written to the Raspberry Pi or to a remote disk. Plates with multiple sample wells at each row/column position are supported, and a script file for automated z-stack depth-of-field enhancement is written along with the images. The graphical user interface and real-time imaging also make it easy to manually inspect and capture images of individual samples.

The present invention relates to a high-temperature furnace for T(O)C measurement of a sample, which has a furnace housing which bounds a vaporization space and has a sample opening for the dropwise introduction of the sample and at least one flushing opening for introduction of a flushing liquid. According to the invention, the furnace housing is lined with a spinel ceramic on an inner side facing the vaporization space. By means of the spinel ceramic, the vaporization space is lined with a material which allows particularly high temperatures within the vaporization space and thus very complete combustion and is at the same time very resistant to temperature changes. This allows cleaning with a flushing liquid at essentially the operating temperature of the vaporization space and removal of deposited salts, in particular recrystallized organic salts, from the vaporization space in the flushing liquid in dissolved or undissolved form. Aging of the high-temperature furnace by deposited salts can thereby be avoided or at least significantly retarded.

In general, this disclosure describes techniques for changing a sampling frequency of a digital signal. In particular, the techniques provide a more accurate way to determining a relative timing between a desired output sample and a corresponding input sample using a non-approximated integer representation of the relative timing. The relative timing between the desired output sample and corresponding input sample may be represented using a first component that identifies a latest input sample of the digital signal used to generate intermediate samples, a second component that identifies an intermediate sample, and a third component that identifies a timing difference between the desired output sample and the intermediate sample. Each of the components may be recursively updated using non-approximated integer values.
