Design of a Multilayer Dual-Band Balanced Bandpass Filter on a Circular Patch Resonator
Authors: Xu Yanhui , Liu Zhengkang , Wang Shiyan , Tang Wanchun , Chen Junxin 
Published: June 2021

This letter presents a novel multilayer dual-band balanced bandpass filter (BPF) design by using two perturbed circular patch resonators. The TM11 mode and TM21 mode of the resonator with odd-symmetric field distributions are explored to realize the desired differential-mode (DM) transmission and common-mode (CM) suppression. Two circular patches are properly coupled in the back-to-back form to realize a dual-passband balanced response by virtue of coupling apertures etched on the ground. In addition to the internal coupling, the above apertures are also further utilized for the undesired degenerate mode harmonic suppression. Besides, slot perturbations on the patch are introduced to perturb the TM21 resonant mode to independently adjust the center frequency of the higher passband, while the lower passband remains almost unchanged. Thus, two passbands can be flexibly controlled by simultaneously tuning the above slots and size of the patch. For validation, a dual-band balanced BPF prototype is implemented. The results indicate 18 and 26% wide fractional bandwidths centered at 5.5 and 7.5 GHz with return loss higher than 20 dB under DM operation and CM suppression higher than 40 dB over an ultra-wide frequency band.

Objectives: Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI) are common in elderly population, and constitute a high-risk group for progression to dementia. Innovative, complex, and engaging non-pharmacological methods of cognitive stimulation, implementable at this stage, are needed. The aim of the study was to determine the effect of Computerized Cognitive Training (CCT) combined with Whole Body Stimulation (WBC) on cognitive functions of older adults with SCD and MCI.Methods: A 9-week single-blind pre/post case control trial was conducted. The study enrolled 84 adults aged 60 or older, allocated to one of two intervention groups: EG; CCT with psychoeducation, EG2; CCT with psychoeducation and 10 WBC sessions, or the control group (CG), which comprised patients receiving usual care. The primary outcome measures were cognitive functions evaluated with MoCA scale and several other neuropsychological tools. Depressive symptoms assessed with the GDS scale constituted the secondary outcome measures.Results: The results show evidence for increased performance in the assessment of general cognitive functioning in both EGs (p ≤ 0.05). Significant improvement was also visible in several cognitive domains, such as verbal fluency (EG1 &amp; EG2), learning ability and immediate memory (EG1 &amp; EG2), delayed memory (EG2), attentional control (EG1), and information processing (EG2) (p ≤ 0.05). However, only in the group with combined interventions (CCT + WBC) the participants presented significantly less depressive symptoms (p ≤ 0.05).Conclusions: The results of the study suggest that CCT, especially in combination with WBC, might be a practical and effective method of improving cognitive performance. Moreover, this combination leads to a reduction of depressive symptoms.

The article highlights the relevance of udder hygiene, sources of milk contamination with microflora, udder treatment requirements, sanitary condition control of the teats skin of cow udders, as well as a list of udder treatment products authorized in Ukraine.
Proper preparation of udder teats for milking, namely: treatment with special detergents and disinfectants, compliance with the correct milking procedure significantly reduce the risk of cows with mastitis and increase milk yield. The content of microorganisms in milk shows the hygiene of milking cows, animal health, and the presence of pathogenic and technologically dangerous microorganisms.
Bacterial contamination of milk is significantly increased due to udder diseases in cows. This increases the bacterial contamination of milk with pathogenic microbes, and the milk becomes unfit for consumption and processing (milk from cows with mastitis must be disposed of) milking procedure significantly reduce the risk of mastitis in cows and increase milk yield.
It is necessary to prevent the penetration of microbes into the teat duct for prophylactic mastitis measures Special products should be used to treat the udder after milking. These products have certain requirements, the main of which are: the ability to quickly destroy bacteria; to keep the skin of the teats in good condition; to protect the teat between milking; easy to wash off before milking to eliminate the risk of getting into the milk.

The aim of the work was to develop and validate a method for the simultaneous identification and quantification of dihydrostreptomycin and benzylpenicillin in injectable suspensions. The method was validated by testing two preparations in the form of injectable suspensions containing benzylpenicillin 108–144 mg/ml and dihydrostreptomycin 180–220 mg/ml. Test samples were dissolved in purified water P, and standard samples: benzylpenicillin - in methanol (up to a concentration of 126 μg/ml), dihydrostreptomycin - in purified water P (up to a concentration of 200 μg/ml). The maximum allowable total uncertainty of the analysis was 1.64%, which is within the recommendations of SFU 2.0. The samples were separated on a Dionex Ultimate 3000 chromatograph equipped with a Luna C18 (2) 250 × 4.6 mm, 5 μm chromatographic column. The mobile phase was a mixture of acetonitrile and a solution of 0.01 M sodium heptanesulfonate with 0.05 M sodium phosphate trisubstituted, acidified with 0.1 M phosphoric acid to pH 6.0, in a volume ratio of 2: 8.
Under mentioned conditions, dihydrostreptomycin and benzylpenicillin were completely separated. The established parameters of the chromatographic system did not exceed the limits specified in the FDA recommendations. The calibration curves were linear in the recommended SFU 2.0 range (80–120% of the nominal concentration of the corresponding active substance). The ratio of the amount of standard sample added to the test samples with its subsequent detection in the preparation was 99.35–100.79% for benzylpenicillin and 99.49–100.12% for dihydrostreptomycin, which does not exceed the limits recommended in SFU 2.0. The precision criterion was 0.07 for dihydrostreptomycin and -0.08 for benzylpenicillin, which is within the limits recommended in SFU 2.0. At the same time, the results of the study by different analysts at different times differed by 1.3% for dihydrostreptomycin and 0.98% for benzylpenicillin, which is well within the limits adopted in the recommendations of the FDA and SFU 2.0.
Therefore, the method developed and validated by us for the simultaneous determination of dihydrostreptomycin sulfate and benzylpenicillin procaine in injectable suspensions can be considered suitable for routine analysis.

The article presents the results of studies on the effects of citric acid on the female’s body. The studies were performed on white laboratory rats of the Wistar line, which at the age of 3 - 3.5 months with a body weight of 192 - 210 g were divided into two groups of 4 individuals in each. The animals of the experimental group were fed by citric acid at a concentration of 80 mg/l of drinking water during the period physiological and puberty, fertilization and pregnancy. A control group of female rats was fed by water. The animals had free access to drinkers and food. Indicators of embryogenesis, leukocyte profile of blood and body weight of animals, weighting factor, histological changes of the liver were determined.
Female rats were found to have no abortions or premature births, however, the number of corpora lutea of pregnancy decreased by 19.2%, although there was no significant difference in control. The number of implantation sites per female was significantly lower by 28.8%. The mortality rate of embryos was 15.8%, which is 3.8 times higher than in intact animals. Regarding white blood cells, the analysis of the results indicates a tendency to increase the percentage of eosinophils in 2 times in the relation to the animals in the control group on the background of a probable increase in leukocytes by 42.4%.
The applied dose of citric acid caused certain changes in the macro- and microstructure of the liver. It is macroscopically established that under the influence of citric acid the organ is slightly enlarged, sluggish consistency and changed its color from light red to light brown. The relative weighting factors of the liver are probably higher in the relation to the control (52.12 ± 8.16 g/kg vs 43.38 ± 1.96 g/ kg).
The results of morphological studies indicate a partial violation of the lamellar structure of the organ in the centro-lobular region, which is due to turbid swelling of the cytoplasm of hepatocytes. In most cells, the contours are blurred, the cytoplasm is poorly stained, their nuclei are weakly basophilic, and hepatocytes with a lysed nucleus in a necrobiosis condition also occur. However, among dystrophic altered cells are clearly isolated hepatocytes with a uniformly colored basophilic cytoplasm, nucleus, rich in chromatin, which indicated the activation of reparative processes. Kupffer cells in this area are mostly round, located in the lumen of the sinusoid. Therefore, occurs a violation of lipoprotein complexes of cells and increase the permeability of cell membranes, which is reflected in the development of protein dystrophy with varying degrees of severity. Activation of reparative processes of hepatocytes is also determined.

Published: June 2021

The long moratorium on state control (supervision) over the activities of business entities has led to an increase in the volume of unregistered, low-quality, counterfeit and counterfeit veterinary products on the Ukrainian market. Violations by manufacturers regarding the entry into circulation of dangerous products are also due to the long absence of licensing of production and sale of products for veterinary medicine and animal husbandry. In these circumstances, there are numerous complaints from consumers about the low quality and safety of veterinary drugs, feeds, feed additives and premixes. The article covers the issues of examination of product appearance, labeling, primary (group) and secondary (transport) packaging, which is carried out in order to establish the conformity of manufactured products to the requirements declared in the regulatory documentation, which will identify dangerous products on the domestic market. In carrying out the examination of veterinary goods presented by consumers and other enterprises or institutions, the general procedure for its conduct shall be established. They check the completeness of the sent materials and check their availability with the corresponding list in the cover letter, open the sealed samples by commission and find out whether the veterinary drug has been registered in Ukraine. Then the data presented in the materials are compared with the registration materials and normative documentation, and a protocol of product inspection for compliance with the requirements declared in the dossier, registration certificates, technical conditions, quality certificates, etc. is drawn up. Examination of the appearance of the label is carried out visually, comparing with the original or with the materials of the relevant registration dossier. Check the correct labeling and packaging of products, and it is important to pay attention to the statement of the summary product of characteristics.
As a result of the procedures for assessing the correctness and reliability of the appearance of veterinary products in accordance with the original sample, registration dossier and regulatory documentation, a conclusion is issued, which provides a detailed description of the research and the conclusions drawn from their results.

Introduction: Pre-clerkship procedural skills training is not yet a standard across Canadian medical school curricula, resulting in limited exposure to procedures upon entering clerkship. While simulated skills training has been documented in the literature to improve performance in technical ability, anxiety and confidence have yet to be investigated despite their documented impact on performance and learning. This study therefore aims to evaluate the effect of pre-clerkship procedural skills training on medical student anxiety and confidence.
Methods: A procedural skills training program was designed based on an evidence-based near-peer, flipped classroom model of education. Ninety-two second-year medical students volunteered for the study. Fifty-six were randomized to the training group, and 36 were randomized to the control group. Students in the training group attended seven procedural skills tutorials over seven months. The control group represented the average medical school student without standardized procedural training. Student anxiety and confidence were assessed at the beginning and end of the program using the State Trait Anxiety Inventory and Confidence Questionnaires.
Results: Students who participated in the procedural skills program demonstrated greater reductions in their state anxiety and greater improvements in confidence compared to the control group.
Conclusion: Longitudinal procedural skills training in the simulation setting has demonstrated improvements in anxiety and confidence among pre-clerkship medical students. These added benefits to training have the potential to ease medical students’ transition into clerkship, while also contributing to a safer and more effective clinical experience. Therefore, future integration of standardized pre-clerkship procedural skills training within medical school curricula should be considered.
