The radiation spectra in the soft X-ray and extreme ultraviolet wavelength ranges of thin-film (0.15 microns thick) targets made of light materials (Si, C, Be) were studied when excited by a Nd:YAG laser pulse with a duration of 5.2 ns focused to an intensity of ~10^12 W/cm^2. Line spectra of BeIII, BeIV, CV, and SiV ions were recorded using a spectrometer based on a multilayer X-ray mirror. A comparison with the spectra of bulk solid-state targets of the same materials is carried out. In all cases, there was a decrease in the intensity of the lines of the soft X-ray spectrum of film targets compared to monolithic ones; the decrease was, depending on the material, from several tens of percent to several times, with more than an order of magnitude less mass of the vaporized substance.

The regularities of the influence of the growth temperature on the geometrical parameters, the concentration of the dopant nitrogen and the type of defects formed in carbon nanotubes grown on a molybdenum sublayer are established in this paper. It is shown that the best piezoelectric and resistive properties are observed in nitrogen-doped carbon nanotubes (N-CNTs) grown at a temperature of 525 ºС, which is due to the highest concentration of dopant nitrogen and high aspect ratio of nanotubes. Based on the results of thermodynamic analysis, the dependence of the dopant nitrogen concentration and the defect type on the tendency to form molybdenum nitrides and carbides during the growth of N-CNTs is shown. The obtained results can be used in the development of nanopiezotronic devices based on arrays of vertically aligned N-CNTs: nanogenerators, strain sensors and memory elements.

By the method of ion-beam shape correction, a small-sized ion beam formed a non–axisymmetric aspherical profile of the collector surface for an extreme ultraviolet radiation source TEUS-S100 with a numerical aperture of NA= 0.25, PV on the surface is 36.3 microns, the surface shape accuracy by standard deviation is 0.074 microns, which allowed to obtain a focusing spot with a width of 300 microns at half-height. To solve the problem, the technological ion source KLAN-53M was upgraded – the flat ion-optical system was replaced with a focusing one. The ion-optical system consisting of a pair of concave grids with a radius of curvature of 60 mm provided the following parameters of the ion beam: the ion current is 20 mA, the width at half–height is 8.2 mm at a distance of 66 mm from the cutoff of the ion source.

In this work, nanophotonic circuits with directional couplers are studied, which, along with phase shifters, are one of the main elements for creating circuits of a linear optical quantum computer. Directional couplers are two closely spaced waveguides, were made of silicon nitride. The subject of the study was the splitting ratio of directional couplers at a wavelength of 914 nm at room (300 K) and helium (3 K) temperatures. On the basis of experimental data, the coupling length at which all the power from one waveguide passes into another was extracted, and the refractive indices of silicon nitride at room (300 K) and helium temperatures (3 K) were found. The results of the work are of great importance in the design and manufacture of fully integrated quantum optical microcircuits with superconducting detectors operating at helium temperatures.

Several new approaches to the measurement of intrinsic noise and dynamic characteristics of superconducting bolometers based on the RFTES technology are demonstrated. The developed methods were tested with an experimental 550–750 GHz sample at reading frequency of ~1.5 GHz at a temperature of 400 mK. The absorption of thin-film resistive coatings on sapphire and quartz substrates was studied, and the emissivity of the experimental heat source was estimated as ~14%. A shot noise source based on Al/AlOx/Al tunnel junction was developed, and the noise temperature of the 1.35–1.6 GHz buffer amplifier referred to the detector output was determined as ~20 K. The response time of RFTES with a hafnium film sized 6 µm × 2 µm × 0.08 µm was evaluated as ~3 µs via microwave heat modulation at the second resonance at ~4.2 GHz; the dynamic range at a modulation frequency of 10 kHz was more than 23 dB. The data obtained made it possible to determine the RFTES sensitivity as 1∙10-17 W/√Hz ± 30%, that coincided with the theoretical value up to the measurement error.

The possibility of precise movement of YVO4:Yb,Er nanoparticles was studied in this work. Such nanoparticles exhibit upconversion luminescent properties and can serve as an accurate low-invasive probe of changes in the local parameters of the medium (in particular, temperature). Using an atomic force microscope, the substrate region with upconversion nanoparticles deposited from the solution and accompanying residues of the synthesis products was cleaned. The use of mechanical marks on the substrate made it possible to compare the atomic force and optical confocal images of the surface and to register the luminescence from an individual nanoparticle. Elemental analysis and luminescence spectra unambiguously identify the nanoparticle as YVO4:Yb,Er.

We studied the use of morphometric variables (maximal curvature, minimal curvature, mean curvature, topographic index, etc.) for study of the surface of X-ray optical elements. We performed calculations on digital elevation models of a spherical concave substrates: primordial and smoothed digital elevation models, before and after technological operations (mechanical lapping, axisymmetric surface shape correction, ion beam figuring). We have demonstrated a visual display of weakly expressed topography inhomogeneities, incl. which are not displayed on the maps of the original digital elevation models. The consideration included the study of both the measured samples and the errors in the formation of the digital elevation model (artifacts from the recording system and from the inhomogeneity of the medium), as well as the features of scale decomposition when using the universal spectral-analytical method.

With the rise in the population of patients with End-stage Renal Disease (ESRD) in Nigeria, there is an increased demand for Renal Replacement Therapy (RRT) including kidney transplantation (KT). We present our initial surgical experience and early outcomes with KT at a Nigerian transplant center over 2 years. A 2-year retrospective review of patients who underwent KT was done. Data of both kidney donors and recipients were recorded in designed proformas. Extracted information included demographic characteristics, side of open donor nephrectomy (ODN), recipient anatomy, surgical techniques and postoperative outcomes. Data were analyzed using SPSS version 21. A total of 210 patients had KT during the period under review. Donors had an age range of 19 to 53 years with a mean of 30.8 3 ± 8.43 years while recipients aged between 9 and 73 years with a mean of 45.97 ± 13.71 years. There were 190 (90.5%) male and 20 (9.5%) female donors. One hundred fifty-four recipients were males (73.3%) and 56 (26.7%) were females. Left ODN was performed in 152 (72.4%) of cases and the commonest indication for right ODN was multiple left renal arteries. The allograft was placed in the right iliac fossa in 187 (89.0%) recipients with the external iliac artery preferred for anastomosis with the allograft renal artery in end-to-side fashion in 182 (86.7%) cases. The internal iliac artery was used in end-to-end fashion anastomosis in 28 (13.3%) of cases. Ureteroneocystostomy using the Modified Lich-Gregoir technique over a double-J stent was performed in all but 5 patients who had uretero-ureterostomies. Significant peri-operative hemorrhage necessitating blood transfusion was experienced in 9 donors and 26 recipients. There was a low complication rate in kidney donors. Allograft renal artery thrombosis, venous thrombosis, and arterial pseudo-aneurysms were encountered in 3, 2 and 4 recipients respectively. Kidney transplantation can be safely and routinely carried out in Nigeria. The early surgical outlook of both kidney donors and recipients was found to be excellent in this study.
Ascertaining the Career Intentions of Medical Students (AIMS) in the United Kingdom Post Graduation: Protocol for a Mixed Methods Study (Preprint)
Authors: Ferreira Tomas , Collins Alexander M , Horvath Rita
Published: June 2023

BACKGROUND

Among doctors in the United Kingdom, there is growing sentiment regarding delaying specialist training, emigrating to practice medicine abroad, or leaving the profession altogether. This trend may have substantial implications for the future of the profession in the United Kingdom. The extent to which this sentiment is also present in the medical student population is not well understood.

OBJECTIVE

Our primary outcome is to determine current medical students’ career intentions after graduation and upon completing the foundation program and to establish the motivations behind these intentions. Secondary outcomes include determining which, if any, demographic factors alter the propensity to pursue different career paths available to a medical graduate, determining which specialties medical students plan on pursuing, and understanding current views on the prospect of working in the National Health Service (NHS).

METHODS

The Ascertaining the Career Intentions of Medical Students (AIMS) study is a national, multi-institution, and cross-sectional study in which all medical students at all medical schools in the United Kingdom are eligible to participate. It was administered via a novel, mixed methods, and web-based questionnaire and disseminated through a collaborative network of approximately 200 students recruited for this purpose. Both quantitative and thematic analyses will be performed.

RESULTS

The study was launched nationally on January 16, 2023. Data collection was closed on March 27, 2023, and data analysis has commenced. The results are expected to be available later in the year.

CONCLUSIONS

Doctors’ career satisfaction within the NHS is a well-researched topic; however, there is a shortage of high-powered studies that are able to offer insight into medical students’ outlook on their future careers. It is anticipated that the results of this study will bring clarity to this issue. Identified areas of improvement in medical training or within the NHS could be targeted to improve doctors’ working conditions and help retain medical graduates. Results may also aid future workforce-planning efforts.

Introduction: Cervical cancer represents an important public health problem. It is the 4th most frequent neoplasm among women in Brazil. Its prevention is carried out in all women from 25 to 64 years old through cytopathological examination of the cervix, based on a screening that allows the detection of lesions and, thus, the early diagnosis of the disease. Objective: To analyze data regarding the coverage of the Pap smear test in women in the state of Pará, Brazil, and the factors related to not performing the test. Methods: Descriptive epidemiological study carried out with data collection from SISCAN and SISCOLO provided by DATASUS. Results: the total sample analyzed was 762,492 patients, among them, the search for disease screening was the main reason for performing it (95.9%); the age group with the highest achievement was 30 to 34 years old (13.33%). In situ and invasive adenocarcinoma subtypes were more prevalent between 40 and 44 years old (18.13% and 20.37%, respectively). Education level was ignored in 98.38%. The test was considered technically satisfactory in 94.71% of the samples and, among them, 39.40% did not have endocervical or metaplastic cells. Conclusion: the Pap test is the best method for tracking and preventing malignant neoplasms of the uterine cervix, directly impacting the epidemiological indices of the disease, due to its early recognition and treatment. Measures such as women's awareness of the subject, proper training of health professionals who carry out the collection, investment in health actions aimed at women and proper completion of notification forms on the platform are of paramount importance for improving the incidence and mortality rates of the cancer, especially in the North region, which has the highest rates in Brazil.

The Science of Deities and Energy Creation in Indian Culture
Authors: Pandey Priya , Mishra Sunil K
Published: June 2023

India’s Vedas and Puranas are collections of sophisticated science that cannot fit into human logic. In this paper, we will discuss the science of creating deities or energy used by ancient India as a tool to have a fulfilled life. This science was widely used in India and not only in India but in South Asia too.This paper will dig deep to know how this sophisticated science works. Atharva Veda or Sthapatya Veda, and sulbha sutras discuss Vedic geometry. Under Vedic geometry, we have Kalpa which discusses methods of performing Vedic rituals. In Kalpa, we have two branches- i- Sulbha Sutra- rules for preparing for Yagya. It discusses the methods and rules for preparing chithi. ii- Srauta Sutra- rules for performing Yagya. In this paper, we will discuss the Sulbha Sutra. We will discuss how differently shaped chithi serve different purposes. We will also discuss Shri Vidya, which is the use of Vedic geometry to worship deities through Yantra. The relevance of Kul Daivam will also be discussed. Cambodia is a south Asian country. Hinduism came to this land in 1st century CE. It was brought by merchants and mercenaries. The early architect of this country tells a lot about the religion and beliefs of these people. Many Shiva lingas and murtis from the early 9th century are found. Shiva was worshipped there for almost 200 years. Angkor Wat Temple, the temple Of Lord Vishnu in Cambodia is the biggest worship site in the world. It was built in the first half of the 12th century. King Suryavarman II was the king of that period. In mid 12th century many libraries, hospitals, and temples were built. After the death of Suryavarman II, Dharanindravarman II came in the late 12th century. With him, Tantric Buddhism came. An enormous change in deities was for a reason. Different deities serve different purposes. This ancient Indian science was spread to parts of south Asia. They used deities as a tool to flourish, conquer, and protect. At last, we will discuss the greatest mathematician of all time Srinivasa Ramanujan. In an interview with his wife, she said“Family told him not to go, and at first he agreed not to. But then he said he was going to Namakkal to ask goddess Namagiri for guidance.” Here she refers to the time Ramanujan decided to go to England he mentioned his devi. He was a live example to use a Deity(Namagiri) as a way to attain intelligence. This was a form of science used all over India but due to many invaders, we lost this knowledge. It is really important to understand and preserve this knowledge. This paper will investigate this science and show how these were always part of Indian culture which we have lost today in the name of science and logic.

Elements of Horror, Grotesque Bodies, and the Fragmentation of Identity in Mark Shelley’s Frankenstein
Authors: Mishra Sunil Kumar , Mishra Parul , Sharma J. K.
Published: June 2023

Gothic books emphasise the occult and the strange. Old buildings (especially castles or apartments with secret passageways), dungeons, or towers serve as the backdrop for the enigmatic events in Gothic literature. Obviously, ghost stories are a well-known form of Gothic fiction. In addition, distant locales that appear strange to the reader serve as part of the setting of a Gothic tale. Even the idea of resurrecting the dead is horrifying. Mark Shelley makes full use of this literary trick to heighten the eerie sentiments generated by Frankenstein in the reader. The idea of resurrecting the dead would have caused the typical reader to recoil in horror and unbelief.

Published: June 2023

A complete understanding of the multitude of roles that people play in the work process, as well as factors that influence people’s decision-making is crucial for accident prevention and operational efficiency through reduction of risk, elimination of any shortcomings, and successful functioning and maintenance of the production process. The method used to analyze, identify, and reduce human errors is a vital aspect of managing a production system.We conducted a study at ArcelorMittal LLC in Zenica, Bosnia and Herzegovina, where the HFACS "Human Factors Analysis and Classification System" approach was applied to identify human errors in accident analysis. The results of this study indicate that the most significant causes of human error and accidents are "preconditions for unsafe acts" (36%), followed by "unsafe supervision" (31%), "unsafe acts" (21%) and“organizational influences” (12%). Based on these results, we concluded that HFACS can be used not only for the identification of human errors but also as a tool for defining corrective measures and reducing human errors.

THE ROLE OF HAZARD, VULNERABILITY AND DAMAGE IN THE GENERATION AND DEFINITION OF ECOLOGICAL RISK CAUSED BY NATURAL HAZARD SOURCES
Authors: Đorđević Amelija , Radosavljević Jasmina , Božilov Aca , Stojadinović Danijela
Published: June 2023

In the 20th century, the study of ecological risk took precedence over studies of other risk types, giving rise to a new scientific discipline within environmental science – ecological risk. This paper presents a structural scheme with basic guidelines to be used when defining risk in general as well as ecological risk. Ecological risk focuses on determining the cause-and-effect relationship between stressors, as hazard elements, and the occurrence of unwanted ecological effects. It is a complex process involving all factors leading to phenomena and conditions that threaten the environment. The paper discusses hazard elements in terms of natural hazard sources, such as floods, landslides, droughts, or earthquakes, whose occurrence causes undesirable environmental effects and which are considered to pose ecological risks. Such risks are defined as a logical interdependence of environmental hazard, vulnerability, and damage.

The problem that occurred in the elderly was a decrease in body function in line with increasing age, one of which was a decrease in cognitive function. Prevention efforts that could be done were by doing physical activity. This study aimed to determine the effect of physical activity on cognitive function in the elderly. The design used in this study was a literature review from database search results that could be accessed through Science Direct, GARUDA, and Google Scholar with articles in the last 5 years (2015-2020). A literature search using the keywords "Physical Activity, Cognitive Function, Brain, Elderly". The search results of 6 articles that had been found using experimental methods showed that some physical activities carried out in the elderly with a duration of administration for 30-60 minutes, with a frequency of 3-5 times a week, and an interval of 1 day for rest could affect and improve cognitive function in the elderly. Physical activity affected cognitive function because regular physical activity could stimulate proteins in the brain to maintain and assist in the process of forming new cells in the brain. Some physical activities that could be done by the elderly included brain exercise, aerobic exercise, healthy walking, and aquatic exercise.

The aim of this research is to make an effort to utilize forestry waste, in the form of harvesting waste of acacia (Acacia mangiumWilld.) and  coconut  shells (Cocos nucifera L.) into particle boards by considering the evaluation of the value of particle board characteristics, both physical and mechanical characteristics in accordance with standards JIS A 5908-2003.This study used a factorial analysis where the first factor was the composition of the raw material for acacia: coconut (100: 0, 60:40, 50:50, 40:60 and 0:100). While the second factor is the provision of pretreatment on particles (cold soak, hot soak and without immersion).This analysis was carried out in a completely randomized design (CRD) with three repetitions.The results showed that the composition of the raw materials had a significant effect on the value of water content, water absorption, modulus of rupture and modulus of elasticity.The pretreatment had a significant effect on the thickness swelling, water absorption, modulus of rupture and modulus of elasticity. Meanwhile, the interaction of these two factors has a significant effect on the internal bond value, modulus of rupture and modulus of elasticity.Based on the results, it is known that only the density parameters that meet the JIS A 5908-2003 standard, the moisture content and thickness development parameters have not met the standards, while the mechanical characteristics of the particle board have not met the standards.Overall particle board with the composition of acacia raw material: young coconut 60:40 and heat soaking pre-treatment can produce good quality particle board.

This research was carried out with the aim of examining the effect of providing palm oil mill effluent (LCPKS) on several soil chemical properties (pH, C-organic, and CEC) and the growth of oil palm seedlings in the main nursery. The research was conducted for 5 months, starting from March 6, 2020 to August 15, 2020 in the main nursery area for  oil palm plantation companies, Belanti Jaya Village, Mersam District, Batanghari Regency, Jambi Province. The research was conducted using a Complete Acaka Design (CRD) based on the age and height of the oil palm seedlings that were uniform. The treatments used were based on the POME dosage, namely 0 L, 4 L, 5 L, 6.6 L, 10 L, and 20 L POME given every week for 20 months. Each treatment was repeated 4 times so that 24 experimental units were obtained and each unit consisted of 4 oil palm seeds so that the total number of seeds used in the study was 96 oil palm seeds. In the maintenance of seedlings, inorganic fertilizers were also given using compound fertilizers, namely NPKMg 15: 15: 16: 4, NPKMg 12: 12: 17: 2, and kiserit. The results showed that POME could increase pH from acidic to slightly acidic to neutral, C-organic from very low to moderate to very high conditions, but it could not increase soil CEC. The highest increase in pH and C-organic occurred in the 20 liter POME treatment. The provision of POME was able to increase height increase, increase in stem diameter, increase in the number of leaves, shoot dry weight, dry weight of the roots of the roots, and be able to provide an index of seed strength so that the seeds were able to be transferred to the field with seedlings of 9 months. The highest increase in oil palm seedling growth occurred in the 4 liter POME treatment.
