The effect of modifying ZnO powders with MgO nanoparticles (with a concentration of 0.1–10 wt. %) on their diffuse reflectance spectra in the region of 0.2–2.5 μm before and after irradiation with 30 keV electrons was studied. Modification of ZnO powder was carried out by MgO nanopowder with concentrations from 0.1 to 10 wt. % using a solid-state method at 650°C heating temperature. X-ray diffraction analysis showed that this method of modification there is no formation of additional phases. It has been established that zinc oxide structure symmetry belongs to the P63mc space group, magnesium oxide – to the Fm–3m space group. The spectral reflectance of such powders in the visible region is over 90%. Under irradiating by 30 keV electrons of initial and modified ZnO powders, as well as MgO nanopowder, a decrease in their reflectance recorded in the entire studied region of the spectrum. It has been established that modification with MgO nanoparticles at a concentration of 3 wt. % leads to an increase in radiation resistance by a factor of 1.32 compared to unmodified samples. This effect is determined by the sink of radiation defects on the large specific surface area of nanoparticles.

A technology was developed for activating ion-implanted dopants in silicon-on-insulator layers at a low annealing temperature (600°C) using the pre-amorphization technique of a silicon device layer. In the case of phosphorus implantation, silicon was amorphized directly by dopant ions. In the case of boron implantation for pre-amorphization, the layers were preliminary irradiated with argon or fluorine ions. Complex diagnostics of the implanted layers was carried out using secondary ion mass spectrometry, X-ray diffractometry and small-angle X-ray reflectometry. The combination of methods made it possible to characterize the impurity distribution, the degree of silicon crystallinity, the layer thicknesses, and the interface widths in structures. The results of diagnostics of the structure and composition correlate well with calculations in the SRIM software package and the electrophysical characteristics of the layers after annealing. It was shown that the use of argon for pre-amorphization of silicon interfered with the recrystallization process and did not make it possible to achieve acceptable electrical characteristics of the doped layer. Amorphization with phosphorus and pre-amorphization with fluorine during boron implantation allowed obtaining the required values of the resistance of the doped layers after annealing at a temperature of 600°C. The use of a complex approach made it possible to optimize the modes of amorphization, ion doping, and annealing of silicon-on-insulator structures at low temperatures, necessary for the creation of light-emitting device structures based on silicon-germanium nanoislands.

Results of generation of various suboxide layers on various thin oxidized niobium films by modification and sputtering of their surfaces with low-current argon ion beams are reported. Niobium films of various thicknesses were grown by magnetron sputtering on oxidized silicon substrates. Few stages of delicate ion bombardment were performed. The surface of films was studied by means of non-destructive methods of X-ray photoelectron spectroscopy and angle-resolved X-ray photoelectron spectroscopy. Chemical and phase film profiling was performed. It was found that during air exposure of niobium films of various thicknesses, layers of pentoxide and various stoichiometric and non-stoichiometric oxides had been generated. During ion bombardment, composition and thicknesses of the films did not change. Numerical modelling results showed that by delicate ion bombardment atoms of oxygen were mostly sputtered. It was the surface pentoxide niobium layer that was sputtered and modified. It was found that different layers of stoichiometric suboxides and pentoxides of other phases different from the initial phases had been formed. The composition of surface suboxide layers changed slightly. The results of this research show opportunity of generation of suboxide layers of various composition and thicknesses by changing parameters of ion irradiation of metal film surface.

Authors: Allayarova G. Kh. , Umirzakov B. E. , Tashatov A. K.
Published: September 2024

Using the methods of secondary ion mass spectrometry, elastic peak electron spectroscopy and Auger electron spectroscopy, the elemental and chemical composition of the surface, concentration profiles of the distribution of atoms over the depth of silicon implanted with O2+ ions with energy E0 = 1 keV at a dose of D = 6 × 1016 cm–2 were studied. It was found that oxides and suboxides of Si (SiO2, Si2O and SiO0.5) were formed in the ion-doped layer, and it also contained unbound O and Si atoms. Post-implantation annealing at 850–900 K led to the formation of a stoichiometric SiO2 layer ~25–30 Å thick.

Published: September 2024

The processes of contact melting of the AMg6 (Al-6%Mg-1%Mn) alloy with Zn–Cu–Al solder and the model Zn–Al alloy, as well as the structure of the contact fusion zone, are studied. Samples were obtained in two stages. At the first step, the solder was mechanically applied (tinned) to the surface of the AMg6 plates. Аt the second step, the resulting composite samples were subjected to heat treatment with a varied exposure time in the liquid state. According to the data of metallographic and X-ray diffraction analyses, as well as differential scanning calorimetry, it was shown that already at the tinning stage the active interaction between Zn and Al occurs, which leads to the formation of a developed microstructure in the joint zone. The presence of copper in the solder HTS-2000 reduces the melting point of the Zn-Al alloy by 30-40°C and improves the conditions for contact interaction with the grade AMg6 matrix. Active diffusion of zinc ensures the formation of an extensive melting zone during heat treatment, while zinc-rich areas during crystallization contain the Zn5Cu intermetallic phase, which prevents the formation of intermetallic ZnxMgy compounds, which does not lead to embrittlement of the contact zone.
Transition Radiation on a Conducting Target Shaped as a Right Dihedral Angle
Authors: Syshchenko V. V. , Tarnovsky A. I. , Krivtsov V. A.
Published: September 2024

The transition radiation of a charged particle in the simplest case of its incidence onto an infinite, perfectly conducting plane can be described using the method of images known from electrostatics. The same method makes it possible to find the field distribution in more complex cases, such as the field created by a point particle in the presence of two intercepting conducting planes, the angle between which divides exactly the angle of 180°. Based on the method of images, a description is given of the transition radiation that occurs when a fast-charged particle falls on a target in the form of two conducting half-planes intersecting at the right angle (on the inside of the dihedral angle). The features of the radiation emitted by fast and slow particles are qualitatively considered, and their visual interpretation is given. The possibility of using interference effects arising from radiation to monitor beams of charged particles is discussed.

Published: September 2024

The contributions of grain boundary and dislocation mechanisms to the experimentally established strengthening of pure Al samples obtained by consolidation of thin foils by high pressure torsion technique were estimated within the framework of well-known theoretical models using structural parameters (sizes of coherently scattering domains and lattice microstrains) determined by X-ray diffraction. Good agreement between the calculated values and the hardness of deformed and aged samples was found, and possible reasons for their differences for the initial foils were discussed. The influence of deformation and aging on the relative contributions of the analyzed mechanisms to the strengthening of samples consolidated from both Al foils and the rapidly quenched Al95.8Mn3.8Fe0.4 ribbons was determined. The structural features of samples processed by high pressure torsion and the relationship between structural parameters and mechanical properties were discussed.

An impact mill has been developed to produce powders from shavings of refractory metals using impact grinding method for reuse in electrometallurgy in devices with screw feed, for example, in 3D printers. The proposed device provides high uniformity of grinding with a minimum content of dust fraction and impurity content at low technical and economic costs. The result is achieved by using a Laval nozzle, which operates in the supersonic jet formation mode. In the area of the first Mach disk there are rod fenders arranged in a cascade, and the impact plate is located in the turbulence zone and is equipped with winglets with holes for separating crushed metal.
VETERINARY ETHOLOGY APPLIED TO A DAIRY GOAT HERD: CLASS REPORT
Authors: Furtado Gil Dutra , Sobral Felipe Eduardo da Silva
Published: September 2024

Environmental stress on farm animals is a limiting factor for all livestock farming. In this sense, the action of professionals, such as veterinarians is essential to outline the best management and the best actions to develop with livestock in a region.
In this manner the results from the study performed by Furtado (2007) presented information on the behavior of dairy goats that favor new evaluations. The influence of the environment on the behavioral parameters of dairy goats was observed in Lajes do Cabugi, Rio Grande do Norte, on a dairy goat production farm.
Ethology is a science that favors the understanding of the adaptation of animals (i.e. behavior) to the environment in which they are found. Therefore, this knowledge field helps the veterinarian in the clinical assessment of animals’ health and well-being, promoting animal aid to achieve greater productivity, which is one of the objectives of the animals' actions professionals.
Through research carried out in a brief bibliographical-secondary survey, the objective of this study is to evaluate the recorded ethogram of a goat herd, which had been exposed at two different times of breeding.
The environmental variations recorded at the beginning and end of the experiment (June and September 2007) were, respectively: i) ambient temperature 25.82ºC and 25.88 ºC; ii) relative humidity 67.48% and 66.64%. The outcome obtained with ethogram was that the animals had many more episodes of lying under the shade in August compared to June, as well as grazing in the shade, brooding in the shade, standing still in the shade and walking. These results show that the herd spent much more energy to maintain homeostasis under heat stress (FURTADO; SILVA; TELES, 2018; GAIA et al., 2019).
It was concluded that the herd must be relocated in terms of access to nutritional supplementation with hay and concentrates, have access to more shaded areas and promote relocation in grazing and stabling hours, with the aim of preventing pathologies linked to heat stress, as well as having a better quality of life and animal well-being.

Published: September 2024

The first Miocene representative of the wasp genus Pristaulacus Kieffer, 1900, is described from the volcanic paleolake of Sainte-Reine in Cantal, France. Observable characters are identical to those of the extant Pristaulacus barbeyi (Ferrière, 1933), currently known from the southern and eastern Mediterranean regions and Iran and associated with mountainous fir forests where it is a parasitoid of buprestid beetles. Interestingly, the paleohabitat of the Sainte-Reine locality was a mountain paleolake surrounded by forests with firs (Abies Mill., Pinaceae) and with a rather cool climate, matching well with the occurrence of a species of Pristaulacus, phenetically at least, similar to P. barbeyi.

Divorce Bureaucracy in the Sharia Space: Examining Practices in Langsa City, Aceh
Authors: Muhazir Muhazir , Azwir Azwir
Published: September 2024

Divorce in the community is often understood differently between Islamic law, the State, and customary law. Each of these laws has a fundamental legal basis regarding the concept of divorce. The impact of differences in the legal concept of divorce results in different Muslim communities in the process of terminating marital relations. This research aims to examine further how the divorce bureaucracy in Indonesia affects the divorce process in the community. This paper results from an empirical study with a socio-legal study approach, this approach is used to review how divorce in society is practiced. Data was obtained from interviews with relevant parties. To strengthen the data and analysis, this research also uses several empirical research results and other important articles related to this paper. The results show that the divorce bureaucracy in Langsa City, Aceh still leaves problems caused by differences in viewpoints and interests so that divorce outside the court still occurs. The difference in perspective is based on the understanding that divorce is legal if it fulfills the provisions of Islamic law. On the other hand, people who are aware of the law have the view that divorce must be done before the court. The bureaucracy of divorce, which involves administration and the conditions that must be met, makes divorce considered complicated and takes a long time. Conversely, religious divorce does not require a long time and cost. In addition, the interest in a quick process without the need for an administrative process also influences the divorce bureaucracy. Non-judicial mediation at the village level is essential for reducing divorce rates and reducing divorce bureaucracy.
The Accuracy of Core Needle Biopsy in Determining Histological Type and Scarff- Bloom-Richardson Grade in Invasive Breast Cancer.
Authors: Kumar Sameer , Kumar Sujeet , Bhardwaj Prashant
Published: September 2024

This 18-month retrospective study examined the accuracy of core needle biopsy (CNB) in diagnosing histological type and Scarff-Bloom-Richardson (SBR) grade in 110 invasive breast cancer patients at Rajshree Medical Research Institute, Bareilly. The study demonstrated 89.1% histological concordance between CNB and surgical specimens, with invasive ductal carcinoma identified with excellent accuracy. However, SBR grade concordance was moderate at 77.3%, suggesting CNB may not consistently reflect tumour aggressiveness. Statistics showed great sensitivity and specificity for histological typing, but CNB results should be interpreted cautiously, especially for grading and rare subtypes. CNB is still a useful diagnostic tool, although surgical examination may be needed to confirm and arrange treatment.

Published: September 2024

This study was undertaken with the explicit objective of comparing the educational curriculum of the Master's program in Geriatrics in Iran with that of the Alberta Nursing School in Canada. This comparative descriptive study employed George F. Bradley's 4-step method, involving the stages of description and proximity analysis. Data were sourced from internal databases, including Magiran and Scientific Information Database, supplemented by external databases such as Google Scholar, PubMed, and Scopus. The geriatric nursing master's program in Alberta is characterized by a longer duration and a more established history. The delineation of roles for graduates in this context is more specific compared to the situation in Iran. The admission criteria in Alberta are more stringent, emphasizing the quality of candidates through a comprehensive evaluation of general and professional factors. Conversely, the admission process for nursing master's students in Iran considers a broader set of criteria. Furthermore, a substantial disparity exists between the course topics in Iran and the pressing societal and clinical needs. The inadequacy of clinical space and the scarcity of experienced professors emerge as significant challenges within the training program in Iran. The formulation of the curriculum for the geriatric nursing master's program should adhere to a systematic and comprehensive framework that aligns with societal needs. Graduates of the program should possess a well-defined professional position within the healthcare landscape. The educational process should involve the utilization of accomplished professors and a dynamic clinical environment to effectively train students.

This study aims to apply Betty Neuman's systemic model in the execution of the nursing process for a patient undergoing Whipple surgery. In this case study, a patient was assessed utilizing Neuman's model, wherein intrapersonal stressors encompassing physiological, psychological, socio-cultural, and spiritual dimensions, alongside interpersonal and extra personal stress factors, were systematically observed. Subsequent to the examination, three nursing diagnoses are delineated, adhering to the categorization stipulated by the International Association of Nursing Diagnosis of North America. Nursing care strategies are formulated based on three levels of prevention (primary, secondary, tertiary), as deemed significant within the framework of Neuman's perspective. The outcomes derived from this assessment informed the classification of nursing interventions and contributed to the categorization and evaluation of nursing outcomes. Consequently, it is advisable to consider the application of Neuman's model, along with other pertinent models, in the context of nursing care for the optimal well-being of patients/clients.

This study aimed to evaluate the relationship between care burden, fatigue, and family functioning among family caregivers of older adults with Alzheimer’s disease (AD). This study adopts a cross-sectional research design, employing an available sampling method. The sample comprises 150 caregivers of elderly individuals diagnosed with AD, recruited from the elderly clinic overseen by the Birjand Welfare Organization. Data collection encompassed the administration of multiple instruments, including a demographics form, Zarit Burden Interview, Piper Fatigue Scale, and APGAR family functioning questionnaires. A total of 150 elderly individuals diagnosed with AD, along with their respective caregivers, were included in this study. The mean score for caregiver burden was 24.24 (SD=10.18), fatigue was 32.73 (SD=22.76), and family functioning was 6.58 (SD=7.37). A negative and significant correlation was observed between caregiver burden and family functioning (r=-0.693, P<0.05). Furthermore, positive and significant correlations were found between caregiver burden and behavioral fatigue (r=0.720, P<0.05), affective fatigue (r=0.674, P<0.05), as well as sensory cognitive fatigue (r=0.484, P<0.05). The association between behavioral fatigue and affective fatigue revealed a positive and significant correlation (r=0.875, P<0.05), as did the correlation between behavioral fatigue and sensory-cognitive fatigue (r=0.488, P<0.05). Additionally, a positive and significant relationship was observed between affective fatigue and sensory-cognitive fatigue (r=0.478, P<0.05). Considering the pronounced relationship between caregiver burden, fatigue, and family functioning, these factors hold utility for researchers and policymakers in the realms of gerontology and intervention planning, serving as pivotal metrics for assessment and intervention design.

The present study aims to determine the effect of the continuous care model on the adherence to the medication regimen of patients hospitalized in the psychiatric ward. This quasi-experimental research was carried out on a sample of 46 patients who were admitted to the psychiatric ward. The data collection tools employed in this research included a demographic questionnaire and an 8-item MMAS-8 medication adherence questionnaire. Before the intervention, the adherence rate to the medication regimen was 2.82 (SD=1.62) in the intervention group and 3.20 (SD=2.50) in the control group. The Mann-Whitney U test revealed no significant difference between the two groups pre-intervention. Post-intervention, the adherence level to the medication regimen increased to 5.56 (SD=1.70) in the intervention group and 3.51 (SD=2.73) in the control group. The Mann-Whitney U test indicated a significant difference (P=0.006) between the two groups post-intervention. The analysis of covariances (ANCOVA) test, after controlling for the pre-test effect, demonstrated that the continuous care model significantly influenced the adherence to the medication regimen among patients admitted to the psychiatric ward (eta=0.26, P<0.01). Consequently, the continuous care model can be attributed to 26% of the changes in adherence to the medication regimen in patients. Owing to the demonstrated efficacy and cost-effectiveness of the continuous care model, it can be integrated into nursing education and management. The implementation of such care models and approaches has been shown to enhance the quality of patient care services. Therefore, it is a viable strategy for improving healthcare outcomes and efficiency.

This research constitutes a case study wherein the implementation of Martha Rogers' Unitary Human Science model was executed on a patient admitted for an angiography procedure. The nursing care, predicated on the Martha Rogers model, was conducted in three stages: pattern appraisal, mutual patterning, and evaluation. In this study, by the patient's needs and the necessary modifications made in their environment, patterns that diminished performance or exacerbated disease were rectified. Consequently, optimal health was achieved for the patient. Hence, it is advocated that nursing professionals incorporate Martha Rogers' theoretical framework into their clinical practice, as it facilitates a holistic approach to patient care.

The present study aims to determine the effect of interactive game therapy with the Theraplay model on students' sleep quality. This randomized control trial study was carried out on a sample of 60 students, aged between 8 to 10 years, in the city of Aliabad Katul, located in the Golestan province of Iran, in the 2023. The study employed a simple random sampling technique, subsequently dividing the participants with random allocation into two distinct groups: a control group and an intervention group, each comprising 30 individuals. The independent t-test revealed no significant difference between the intervention and control groups before the intervention (P=0.64). However, a significant difference was observed between the two groups post-intervention (P<0.01), as indicated by the independent t-test. The paired t-test demonstrated a significant difference in the intervention group before and after the intervention (P<0.01), but no significant difference was found in the control group (P=0.8). Furthermore, the analysis of covariance (ANCOVA) indicated a significant difference upon controlling for the pre-test effect (P<0.01 and Eta=0.26), suggesting that 26% of the changes observed in the post-test can be attributed to the intervention. Consequently, administrators and practitioners in the fields of health and education must employ this model of non-pharmacological treatment methodologies to enhance and ameliorate the sleep quality of school-aged children.

The objective of the current study is to ascertain the clinical audit of nursing care about the administration of tissue plasminogen activator (t-PA) drugs in patients diagnosed with cerebral thromboembolic stroke. In this quasi-experimental study, a total of 16 triaged cases of patients with acute cerebral embolic stroke, referred to both the emergency and neurology departments, were examined. These cases were divided into two groups: intervention and control. The method of event sampling and a three-part checklist for t-PA drug injection were employed through a six-stage clinical audit process. In the current investigation, the mean age of the participants in the control group was 57.63 (SD=3.58), while in the intervention group, it was 55.51 (SD=3.58). The adherence to nursing care protocols before the administration of the t-PA drug witnessed a significant enhancement following the execution of the clinical audit cycle (P=0.045). Similarly, the compliance rate of nursing care during the injection of the t-PA drug also saw a significant rise after the implementation of the clinical audit cycle (P=0.02). The nursing performance metrics improved after the clinical audit cycle’s implementation. Specifically, the proportion of nurses exhibiting good performance escalated from 62.5% before the audit cycle to 87.5% after its implementation. However, this difference did not reach statistical significance (P=0.18). Given the substantial impact of the clinical audit process on the quality of delivered services, it appears that this process can contribute to the enhancement of the service level provided by nurses in clinical environments.

Since the start of the epidemic, Iran has been severely impacted by the Coronavirus Disease 2019 (COVID-19). Therefore, measuring the level of fear and anxiety in students can effectively help policymakers and educational administrators to be able to take practical actions to reduce fear and anxiety in students by using existing mechanisms. This research investigated the anxiety and fear in Iranian university students during the COVID-19 pandemic and explored the potential influential factors. Data on participants was collected using a web-based cross-sectional survey using an online questionnaire distributed via social media platforms. The Corona Disease Anxiety Scale and Fear of COVID-19 Scale measured the presence of anxiety and fear in participants. The Odds Ratio (95% CI) was calculated using logistic regression models. A total of 1,146 individuals with a mean age of 22 (SD=3.67) years participated in the study. The prevalence of anxiety among participants was 30.9%. The mean anxiety and fear of COVID-19 score among the participants was 13.71 (SD=4.51). According to this study, the adjusted odds of having psychological symptoms, physical symptoms, and total anxiety increased in subjects who were not single and Ministry of Science or Research and Technology (MSRT) students. The adjusted odds of psychological symptoms and total anxiety were also decreased in the individuals who sometimes and rarely followed COVID-19 news. Physical symptoms were reduced in some of the family members who did not have COVID-19 and in those who were not concerned about universities being opened and the adverse effects of COVID-19. University students have been significantly affected by the COVID-19 confinement. It has been suggested that universities must prioritize the mental health of their students during such challenging times.
