Authors: Hynniewta Barry Cooper , Phanjom Probin , E. Kurbah Ronald , Slong Mynso Kapil
Published: March 2023

Infertility is a condition of the reproductive system that can affect either the male or the female and is characterized by a failure to achieve pregnancy after 12 months or more of consistent sexual interaction that is not protected. Within the scope of the present study, we aim to look into the prevalence of male infertility with an emphasis on Sperm DNA fragmentation over its importance in conjunction with a semen analysis. Our objective is to confirm the diagnosis of male infertility not be solely dependent on semen analysis alone; however, confirmatory diagnostic test such as Sperm DNA fragmentation needs to be incorporated into the routine investigation. This study marks the first documented report on male infertility in Meghalaya. Using the Makler counting chamber and Sperm 360 DNA Fragmentation, examination of the seminal fluid of two hundred and one males to look for signs of infertility. It was done by looking for aberrant sperm in the sample. During examinations of the two hundred and one patients for infertility, it was discovered that the rate of male infertility stands at 57.21%. The asthenozoospermic was 36.32%, oligozoospermic was 1.49%, and azoospermia was 8.96%. Oligosthenozoospermia was reported to have been 7.96% and polyzoospermia1.00%, respectively. DFI between fertile and infertile men was (11.02 vs. 37.88, p<0.001). Therefore, testing for sperm DNA fragmentation after semen analysis is an effective method for determining the cause of infertility. The prevalence rate of men with infertility was 57%, indicating that it was significantly higher than expected. As a result, appropriate treatment procedures must be carried out while managing male factor infertility.

Published: March 2023

Price elasticity is an important indicator of alcohol consumption. The success of an alcohol policy largely depends on how sensitive the demand is to the price. The purpose of this paper is to determine the effect of vodka price changes on the amount of vodka and pure alcohol consumed by Russian citizens exploiting the variation caused by price regulations, and in particular, taxation. Demand for alcohol is sensitive to its price, as abundant research has shown. However, the price of alcohol, in turn, may depend on demand. To overcome the endogeneity, we used a sharp change in excise tax observed in Russia in 2011 to model the price of vodka using the regression kink design. Based on nationally representative households and individual survey data, we also used the Arellano–Bond method to take into account habit formation. Our results are close to those obtained in other countries but differ from price elasticity values calculated in some work based on Russian data. The results confirm the effectiveness of the tax policy in those years when it increased the real prices of alcohol.

Authors:   CEMA University, Buenos Aires, Argentina, Coloma Germán
Published: March 2023

This paper analyzes the issue of demand estimation and market definition in industries where products differ according to their quality levels. An econometric methodology based on substitution elasticities is explained, and then applied to the Argentine beer industry, using data from the period 2011–2017. The results are compared to equivalent ones obtained using an alternative methodology, concluding that in Argentina we can identify two relevant markets inside the beer industry (corresponding to high/medium quality beers, and low quality beers).
Exergy Analyses of Vehicles Air Conditioning Systems for Different Refrigerants
Authors: KEVEN Arzu
Published: March 2023

There are a limited number of studies in the literature that include detailed exergy analysis of vehicle air conditioning systems. In this study, in order to increase the performance of the air conditioning system in vehicles, a detailed exergy analysis has been made with the assumption that different refrigerants are used. R-134A, R-E245cb2, R-404A, R-1234ze(Z), R-161, R-1234zd(E), R-513A, R-1234ze(E) and R-1234yf has been chosen as the refrigerant. In the analysis, a comparison has been made by considering the environment, performance and safety values. While the COP values of the cycles increase with increasing evaporator temperatures, the COP values decrease at increasing condenser temperatures. On the other hand, exergy efficiency decreases with increasing evaporator and condenser temperatures. Also it is aimed to evaluate all the elements of a vehicle air conditioning system with exergy analysis.
Transient voltage stability assessment based on transfer learning for small samples
Authors: Zhang Jiayi , Ren Hui , Wang Xi , zhibin zheng , Lu Jinling , Wang Fei
Published: March 2023

Large penetration of renewable energy sources into the power grid has
increased the complexity of power system operation and greatly reduced
the ability of the system to withstand large disturbances. The frequent
occurrence of voltage instability problems in the power grid has brought
new challenges to the assessment of transient stability analysis of the
power system. To achieve fast and accurate assessment of transient
voltages, a transfer learning-based transient voltage stability
assessment with small samples is proposed, introducing a domain transfer
learning approach, embedding a cooperative attention mechanism in the
residual network during the feature extraction stage to capture
long-range correlations between features, and using adversarial
approaches to reduce the differences between samples from different data
sets, using the source domain to guide the target domain for network
training to improve model’s evaluation capability when the number of
samples is insufficient, enhance the generalisation performance of the
network, and effectively improve the performance of real-time power
system transient voltage stability evaluation in the absence of
sufficient historical data. Testing on an improved New England 39-node
system validates the superiority of this method in transient voltage
stability assessment and provides a new approach to practical field
transient voltage stability assessment.
Effects of soil factors on Pedicularis kansuensis invasion in alpine grassland
Authors: Liu Yanyan , Li Haining , Fang Fei , Li Kaihui , Zhao Jin , Gong Yanming
Published: March 2023

Root hemiparasitic Pedicularis kansuensis is an invasive native species
in China and has been expanding in the Bayanbulak Grassland of Xinjiang
Uygur Autonomous Region over the past decade, threatening the local
livestock industry. To understand why this damaging species expands in
some areas but not in others, we compared soil water content, soil
nutrient status, and plant community structures between heavily infected
and non-infected sites. We hypothesized that soil nutrient levels and
plant species composition would be more beneficial to the spatial
expansion of P. kansuensis in heavily infected areas than in
non-infected ones. Quadrat (1 m × 1 m) surveys were carried out in the
Bayanbulak Grassland. Species number, percent vegetation cover,
aboveground plant biomass, plant height, and relative frequency were
recorded. Three topsoil samples were taken at 0–10 cm depth from each
quadrat and their nutrient statuses were determined. The results showed
that (1) P. kansuensis invasion reduces the species richness of the
community compared to the uninvaded area (3.07%), but increases the
canopy cover overall (16.99%); (2) soil water content (SW) and soil
nutrient content are the main factors that determine invasion by P.
kansuensis, and SW plays the more important role; (3) SW controls P.
kansuensis leaf stoichiometry, decreases the Ratio of leaf nitrogen (LN)
to leaf phosphorus (LP), and affects LP (P < 0.005). Finally,
after combining the results, we found that the soil factor accounted for
46.50% and plants accounted for 22.50% of P. kansuensis invasions in
the Bayanbulak Grassland.

Published: March 2023

Introduction United Kingdom medical graduates can apply for
speciality training after completing a two-year internship (Foundation
Training). Post-foundation training application requirements vary
depending on speciality but fundamentally require key skills such as
teaching, research, and leadership. We investigated whether medical
student demographics impact their familiarity with post-graduate
training pathways and application process. Methods This was a
cross-sectional study using a Bristol Online Survey. All UK medical
students were invited to answer a range of questions on their
demographics and perceived familiarity with Post-Foundation Training
Pathways (PFTPs) and Post-Foundation Application Process (PFAP). The
data was collected between March 2022 and April 2022 and exported for
further analysis. Statistical analysis was conducted in Stata v.17.1
using Chi-square tests. Results 850 students from 31 medical
schools took part. Male students were found to be more familiar with
PFTPs and PFAP compared to female students (p<0.001).
Similarly, students from Black, Asian, Mixed Ethnic (BAME) backgrounds
expressed significantly lower familiarity (p<0.001) with PFAP
compared to their white counterparts. Younger participants reported
lower familiarity with PFAP (p<0.001). Students from a medical
background expressed a significantly higher familiarity with PFTPs and
PFAP (p<0.001). Conclusion The impact of gender,
ethnicity, age group and medical background on medical students’
self-reported familiarity with PFTP and PFAP are significant. Further
studies are required to evaluate the impact of demographics on tested
knowledge of PFTPs and PFAP and whether this impacts success rate at
post-foundation applications.

Published: March 2023

Purpose: This study aimed to evaluate the influence of
DRG-based hospital payment system approach on implementation of
inpatient treatment. Methods: This study was largely based on
retrospective analysis of DRG-based hospital payment data from
third-class hospital for the period of October 2021 to February 2022
including determination of diagnosis groups with most significant
balance of payment loss and corresponding departments, development of
pathways to DRG-based inpatient treatment, pre-checking of
prescriptions, in process education of clinical pharmacists and case
follow up, comments and penalty measures. The rational drug use, drug
income proportion and DRG-related medical services capability assessment
(manageable number of DRGs, CMI, average hospital stay, time consumption
index and resource consumption index) of departments with loss were
compared before and after intervention. Results: Data analysis
revealed that BR23 (cerebral ischemic stroke with accompanying diseases
or complications) balance of payments loss was most significant with
higher average drug income proportion than such in groups of balance of
payments surplus. The Neurology Department BR23 demonstrated significant
balance of payment deficit. Therefore, the ischemic stroke drug clinical
treatment pathway was successfully developed and after intervention,
prescription errors counted 14.14, therefore demonstrated 6.89%
decrease and at the same time medicines consumption rate was 27.17%
with 9.43% decrease. The number of manageable number of DRGs increased
by 3, CMI increased by 0.14, average length of stay decreased by 0.8
days, time consumption index and resource consumption index decreased by
0.11 and 0.18 respectively. Conclusion: DRG-based hospital
payment management of inpatient treatment provided theoretical support
for DRG code-based reimbursement cost control and scientific cost
control and has improved quality management of hospital service.
Circularly Polarized W-Band Leaky-Wave Antenna Based on a Polarization Converter
Authors: Singh Shilpi , chauhan shakti , Basu Ananjan
Published: March 2023

This article presents a high-efficiency circularly polarized slotted
waveguide leaky wave antenna at the W band. A linearly polarized
beam-steering antenna is designed by creating an array of longitudinal
slots on the WR-10 waveguide and to achieve circular polarization, a
single-layer polarization converter has been used. A new technique has
been proposed to enhance the overall efficiency of the antenna. The wall
thickness of the waveguide containing the radiating slots is reduced to
increase the overall radiation efficiency of the provided antenna. The
gain of the prototype antenna is above 20 dBi in the intended operating
band from 92 GHz to 98 GHz. Furthermore, the antenna provides an average
half-power beamwidth (HPBW) of 3.2° in the elevation plane and a
cross-polarization below -18 dB in the main beam direction. Attributed
to robust structure, reliable fabrication, and simple antenna
configuration as well as its superior performance, the proposed
structure is a strong candidate for various W band applications.

The role of soil solarization and biofumigation on Fusarium and nematode diseases of cucumber and tomato was investigated in this study. Appropriate antifungal and nematicidal biofumigant were selected by in vitro screening of 5 cultivated crops (Mustard, cauliflower, cabbage, radish and broccoli), and 5 weeds (Eruca sativa, Nasturium sp., Lepidium sp., Diplotaxa sp. and SisymbriumirioL.) against Fusarium oxysporum and root knot nematodes (Meloidogyne incognita). Broccoli leaf extract was found to be the most effective in inhibiting mycelia growth of F. oxysorrium. While, cabbage, cauliflower and broccoli were found to have the most nematicidal activity against M. incognita, respectively. Biofumigation with brassicaceous green manures for controlling F. oxysporium and root knot nematode on cucumber was evaluated under field conditions during two subsequent growing seasons in Al-Baq'a and Al-Karama area. Results indicated that using brassica residues significantly reduced the root galling index in both locations. Also, results showed a significant increase in the yield when the brassica residues were used. Moreover, using residues of cabbage and cauliflower were as effective as Vydate in reducing nematode infection and significantly reduced the gall index. Using brassica residues exhibit a significant reduction in the incidence of infestation of F. oxysporum at Al-Karama area. In another experiment soil solarization and biofumigant were applied alone or in combination to be evaluated to manage the soil borne disease of cucumber in the field. Among the different treatments, combined application of soil solarization and biofumigation was appeared to be superior in a significant reduction in root galling and disease incidence of F. oxysporum compared with solarization alone or only biofumigation, also using biofumigation with solarization resulted in a significant increase in the yield compared with the other treatments.

Published: March 2023

Klebsiella pneumoniae is an important opportunistic pathogen that commonly causes nosocomial infections and contributes to substantial morbidity and mortality. The bacteria are not airborne, so you can't contract a K. pneumoniae infection by breathing the same air as an infected person. Instead, K. pneumoniae is spread through direct person-to-person contact, such as when someone with contaminated hands touches a wound. Infections can also occur through the use of contaminated medical equipment. For example, people on ventilators can contract Klebsiella pneumonia if their breathing tubes are contaminated with the bacteria. Similarly, the use of contaminated intravenous catheters can lead to bloodstream infections. The symptoms of a K. pneumoniae infection differ depending on where the infection is located and are similar to symptoms of the same diseases caused by other microbes. For instance, meningitis from K. pneumoniae produces the hallmark symptoms of bacterial meningitis, including fever, confusion, neck stiffness, and sensitivity to bright lights. Bloodstream infections (bacteremia and sepsis) from Klebsiella can cause fever, chills, fatigue, light-headedness, and altered mental states. This study aims to investigate the prevalence of multidrug resistance in Klebsiella pneumonia (MDR-KP).

In this study, the humidity detection properties of the ceramic with composition (Na0.5Bi0.5)0.94Ba0.06TiO3, noted (NBT-06BT), were investigated. The NBT-06BT ceramic was synthesized by the semi-solid method and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The NBT-BT ceramic material sintered at 1100 ?C, crystallizes in the tetragonal system without any secondary phase and presents a heterogeneous distribution of polyhedral shaped grains with open intergranular porosities. The electrical and dielectric properties investigations show that the NBT-06BT ceramic material exhibits excellent humidity detection characteristics such as high sensitivity, good linearity and narrow hysteresis. The impedance decreases by three orders of magnitude when the relative humidity increases from 15 % to 90 % at 100 Hz. The maximum hysteresis value of the sensor is 4.69 % RH. The response time and the recovery time are about 68 s and 125 s respectively. Moreover, the sensing mechanism has been discussed in detail by analyzing the complex impedance spectra. These results indicate the potential application of the ceramic material NBT-06BT as a humidity sensor.

Published: March 2023

Purpose: To investigate the epidemiology and characteristics of patients with enterocutaneous fistulas in our hospital. Methods: A single-center study was conducted in our hospital to collect data on patients with ECFs from November 27, 2013 to December 31, 2019. These data included patients’ general information, common diseases and conditions, characteristics, treatments, and outcomes. Results: Patients (N = 218) with enterocutaneous fistulas were enrolled in the study, including 152 males and 66 females (median age: 52 years). Changsha city had the largest number of patients (39.9%), 79.8% of cases had a single enterocutaneous fistula and 92.2% were related to surgeries. Gastrointestinal tumor (25.7%) was the most common primary disease, and small intestine fistula (44.0%) was the most common enterocutaneous fistula. Approximately 51.8% of patients visited tertiary hospitals first and only 22.5% received definitive surgery. However, only 57.3% of patients were cured, which was related to their first-visited hospital (p = 0.039) and undergoing definitive surgery (p = 0.024). The time from the operation to the enterocutaneous fistula diagnosis for 40.0% of patients was within 1 week after the initial operation, and the length of stay for the first hospitalization of 90.8% was one week to half a year. Some patients had complications, such as diabetes (10.1%). Our analysis showed a significant association of malnutrition with cure rate (p = 0.013). Conclusion: The cure rates of enterocutaneous fistulas were associated with the first visited hospital, definitive surgical treatment, and malnutrition

The younger generation is one of the elements of society that is expected to maintain regional languages amid the development of globalization since they are the portrait of the cultural future. This study aims to measure the level of vitality of the Krama Madya language from the perspective of the young Javanese generation in Malang. The measurement framework used in this study is adopted from UNESCO language vitality measurement factors. Data were obtained from 100 young Javanese generations aged 17-27 years who live in Malang City with various backgrounds using the cluster random sampling technique, ranging from students, teachers, government agencies, and employees to traders, by distributing questionnaires, interviews, and direct observations in the field. The data were analyzed using a qualitative descriptive analysis framework adopted from Miles and Huberman (1994). This study indicates that Javanese Krama Madya among the young Javanese generation, based on nine factors of language vitality to measure the level of UNESCO language vitality, is categorized as vulnerable. The indication of this conclusion is based on the diminishing number of language transmissions between generations; the unavailability of literacy that supports the teaching of the language; as well as the negative attitude of the younger Javanese generation, as shown by the shift in the use of this variety with Indonesian and foreign languages in interactions with older and respected speech partners to show their politeness.

Indonesia mengalami peningkatan jumlah pekerja tidak tetap (precarious employee) sejak tahun 2016. Hal ini menunjukkan bahwa semakin banyak pekerja yang tidak mendapatkan pekerjaan yang layak. Penelitian ini bertujuan untuk mengidentifikasikan karakteristik pekerja dengan status precarious employee dan faktor-faktor yang menyebabkan seorang pekerja berstatus sebagai precarious employee. Penelitian ini menggunakan data Survei Angkatan Kerja Nasional (SAKERNAS) periode Agustus 2019 dengan metode regresi logistik biner. Hasil penelitian menunjukkan bahwa pekerja laki-laki, kawin atau pernah kawin, memiliki pendidikan hingga maksimal SMA, tinggal di wilayah perdesaan, pernah memiliki pekerjaan sebelumnya, tidak terdaftar atau tidak mengetahui serikat pekerja, dan bekerja di sektor pertanian memiliki kecenderungan yang lebih besar untuk berstatus sebagai precarious employee. Sementara pekerja usia muda lebih berpeluang untuk berstatus menjadi precarious employee. Semakin kecil pendapatan pekerja maka menunjukkan bahwa pekerjaannya merupakan pekerjaan tidak tetap. Pemerintah dapat berkonsentrasi memberikan bantuan pada kelompok pekerja yang memiliki karakteristik rentan menjadi pekerja tidak tetap seperti menambah program peningkatan pendidikan dan kemampuan kerja pada pekerja dengan pendidikan SMA ke bawah serta memperluas jaminan kesejahteraan pekerja di wilayah perdesaan dan pekerja di sektor pertanian.

The Fluidity of Borderlands
Authors: Brady Lindy
Published: March 2023

This introduction to the special issue considers the central themes raised by the volume’s contributions as a whole, focusing on their collective interest in the political and cultural — as opposed to geographical — fluidity of borderland zones in early medieval Britain. To highlight these important points, two case studies from the Anglo-Welsh border region are discussed: the Old English legal text known as the Dunsæte Agreement or Ordinance concerning the Dunsæte and the tradition preserved within some Welsh law texts that legal reforms were enacted by the Welsh ruler Bleddyn ap Cynfyn (king of Gwynedd from 1064 to 1073), both of which underscore the fluidity of frontiers on a political level.
