These models are able to predict a fatigue life of composite laminates, but their identification requires a significant number of off-axial tests for various stress ratios. The present study proposes the stress ratio dependent model, which phenomenologically adopts a decrease in stiffness and residual strength of a unique ply according to experimental constant life diagrams.

The abradable coatings had significantly enhanced turbomachinery performance by acting as a sacrificial seal between rotating blades and stationary casing. Further improvement in seal design to meet the higher energy demand and increase the service time has been the key challenge to solve in the gas turbine industry. Honeycomb seals have become the industry standard clearance seal technique due to their unique design and high structural strength with minimum weight.

To investigate the mechanisms by which GCH1 deficiency may contribute to PD, we generated a loss of function zebrafish mutant (), using CRISPR/Cas technology. zebrafish develop marked monoaminergic neurotransmitter deficiencies by 5 d postfertilization (dpf), movement deficits by 8 dpf and lethality by 12 dpf.

Context: Recommendations for COVID-safe, in-person, high school education have included masks and distancing between students but do not describe a scalable surveillance solution to rapidly identify and mitigate disease prevalence or exposure.
Methods: Through an Internet application, all school participants reported symptoms, illness, or exposure daily. Physician-supervised follow-up interviews were reviewed and recorded in daily rounds.
Continuous improvement of protocols for the treatment of various ailments, in particular, osteochondrosis, is one of the important tasks of providing medical care to elderly patients. Supplementation of treatment with Cytoflavin and biofeed-back therapy seems to be a promising solution, however, it is necessary to develop an algorithm to predict it effectiveness in patients taking into account their initial clinical and psychophysiological status. As a result of the treatment, predictors of the effectiveness of the use of Cytoflavin and biofeed-back therapy have been identified and an algorithm for their administration has been developed.

These methods seem to be a simple and effective means of correcting negative changes in the FS of elderly hockey players after a training cycle and ensuring the possibility of a more complete recovery of their body. The difference in the points of application made it possible to combine the intake of Cytoflavin and biofeedback training into a single complex correctional and restorative technique.

A comparative analysis of surgical treatment of non-small cell carcinoma of lung was made in 64 patients of senile age and more young patients. It was stated, that preference should be given to the partial lung resections (lob- and segmentectomies). The authors recommended to avoid pneumoectomy and typical resection of the lung as non-radical operations accompanied by high rate of local recurrences.

Crude oil and petroleum products are widespread water and soil pollutants resulting from marine and terrestrial spillages. International statistics of oil spill sizes for all incidents indicate that the majority of oil spills are small (less than 7 tonnes). The major accidents that happen in the oil industry contribute only a small fraction of the total oil which enters the environment.

An analysis of treatment results was made in 226 patients with multiple isolated intrapulmonary metastases of solid tumors. It appears that surgical removal of metastases was possible in patients with satisfactory functional resources and accurate evaluation in order to validate the indications for surgery. The operation shouldn't result in considerable reduction of quality of life and didn't prevent using other methods of treatment such as medicamental and radiation therapy.

Difference of the functional activity of both types of cells depending on the PT form was revealed: more significant increase in the oxygen-depending activity in FCPT while bactericide potential estimated with a zymosane induced NST-test was more pronounced in IPT patients. These data correlate with the blood levels of neopterin and elastase, the markers of the M and N activity, respectively.

Whereas earlier studies employed a range of Affymetrix SNP microarrays comprising from 10 K to 500 K SNPs, this most recent investigation used the 6.0 chip which displays 906,600 SNP probes and 946,000 probes for the interrogation of CNVs (copy number variations).

A single base variant in MTHFR gene (C677T) results in the production of a mildly dysfunctional thermolabile enzyme and has recently been implicated in BD.

The resection specimens from 31 patients with fibrocavernous tuberculosis (FCT) underwent a complex clinical andimmunological study, as well as a morphological one. It was ascertained that partial or extended lymphadenectomy did not always positively correlate with an adequate postoperative immune response and it depended on the morphological features of lymphatic apparatus lesion. The direct results of surgical treatment of patients with FCT suggest that in patients with specific lymphadenitis and cell-mediated immunodeficiency, the frequency of postoperative specific pleuropulmonary complications and their severity considerably exceed those if there is an adequate immune response.
