Sensor Network Based Testbench Implementation of Landslide Early Warning System
Authors: Chapagai Kamal K.
Published: October 2021

The paper presents an implementation of prototype based Early Warning System (EWS) to detect and provide early warning of Landslide activities. The main aim of this work is to implement the prototype with low cost sensor network. A simulation setup and a table based prototype setup was implemented to study the capability and effectiveness of the system. The setup consists of table based setup of landslide with multiple/changing angle from 30° to 90°. Multiple sensing elements including rain sensor to detect presence of rain, soil moisture sensor to detect the moisture content, temperature and humidity sensor to detect humidity in the environment and vibration sensor to detect movement in the soil was implemented. The data captured by the sensing element is transmitted to a microcontroller which sends early warning signal represented by LED, Buzzer and sending of SMS or call. Through the setup, it is found that the sensitivity of the moisture sensor is rather limited however the range of moisture content detected by the sensor is functional. The vibration sensor can be tuned to have high sensitivity to the movement of the soil however, a number of false positive outcome may be detected. The early warning system is still possible by using multiple sensing element and averaging over their outcomes. The early warning system using low cost components as prototype has been successfully demonstrated. This setup can be scaled up to a real field implementation after careful tuning.
Spatio-Temporal Analysis to Dynamically Map and Audit Urban Growth in Peri-Urban Areas
Authors: Fouda Yasser ElSayed , ElKhazendar Deena Mohamed
Published: October 2021

Villages located today in the peri-urban area, are in continuous agglomeration. The lack of proper guidelines and monitoring systems to define, promote, regulate and manage the pattern of development in these areas, causes massive deteriorations to the environment and quality of life. In Egypt, very few states have a dedicated legal framework that addresses the need for planned development in the peri-urban areas. A Spatio-temporal model framework consisting of a set of geospatial indicators is required to regulate and direct the growth and development of these areas and prevent further spill across administrative boundaries. This article responds to the lack of a geo-spatial quantifiable criterion as a key to detect, analyze, and better govern spatial and temporal patterns of urban growth in peri-urban areas, where the results are to be represented dynamically in forms of spatial patterns evolving in time. The research aims to develop a process-wise, contextual mapping of peri-urban dynamics using GIS to detect and analyze spatial and temporal patterns of urban growth. It has been applied to one of the peri-urban areas in Egypt, in Meet Assas Village, chosen as a case study. Miscellaneous primary and secondary data sources together with the methods used for monitoring: UN Criteria (Goal 11) targets, thematic headlines, village’s problems and geo-spatial indicators were the main constitutions of the model frame work. The results show that the village is characterized by a dispersed pattern of development with the absence of basic infrastructure and services. Besides that, the study reveals, through temporal patterns, that the future and unplanned growth will continue to intensify; posing numerous threats on the environment and the quality of life. A harmonized standardized measurement framework for planning, development, and management is crucial rather than demolishing these areas.

Authors: Shamie Mohamad Mohamad , Almustafa Muhammad Mazen
Published: October 2021

Data mining is a process of knowledge discovery to extract the interesting, previously unknown, potentially useful, and nontrivial patterns from large data sets. Currently, there is an increasing interest in data mining in traffic accidents, which makes it a growing new research community. A large number of traffic accidents in recent years have generated large amounts of traffic accident data. The mining algorithms had a great role in determining the causes of these accidents, especially the association rule algorithms. One challenging problem in data mining is effective association rules mining with the huge transactional databases, many efforts have been made to propose and improve association rules mining methods. In the paper, we use the RapidMiner application to design a process that can generate association rules based on clustering algorithms.

Published: October 2021

Background: Trastuzumab is an efficient monoclonal antibody used in the treatment of Her2-positive breast cancer. Despite its prominent effect on Her2-positive patients’ disease-free Survival. Trastuzumab-induced cardiotoxicity is still one of the main challenges.  Angiotensin-converting enzyme inhibitors (ACE inhibitors) are one of the most potent agents used in heart failure, which also showed confirmed cardioprotective effects against anthracycline and doxorubicin. We aimed to assess the cardioprotective effects of Carvedilol in a randomized clinical trial study.
Materials and Methods: sixty non-metastatic Her-2 positive patients (30 cases; 30 controls) were entered into the study via a simple randomization method.Carvedilol was administered for the patients with the starting dose of 3.125 mg twice a day and started 7 days before trastuzumab administration. The dose has been increased in a three-week period to reach 12.5 mg twice a day and continued until the end of therapy. All the patients underwent an echocardiography after receiving Adriamycin and Cyclophosphamide in order to measure basal Ejection Fraction (EF) and Pulmonary Artery Pressure (PAP). Each patient underwent a follow-up echocardiography in 3,6,9 and 12 months after initiation of the treatment. Finally, all the patients went through the last episode of echocardiography 1 month after the end of treatment. All the Measured PAP and EF has been recorded and analyzed
Results: EF and PAP changes for both groups had no significant changes during the course of treatment with Trastuzmab (p-value = 0.628 and p-value = 0.723, respectively). Seven patients in the intervention group and 2 patients in the control group presented with EF decrease. Also, 8 patients in the intervention and 9 patients in the control groups showed PAP increase.
Conclusion: According to our results, in patients with HER2-positive breast cancer treated with trastuzumab, Carvedilol showed no significant protective effect on trastuzumab-induced cardiotoxicity.

Published: October 2021

Background: One of the important causes of mortality and morbidity in kidney transplanted patients is Post Transplant Lymphoproliferative Disease (PTLD), which is due to immunosuppression therapy and viral activity. It seems that Rapamycin, with dual antineoplastic and immunosuppressive effects, may have a pivotal role in the treatment of PTLD patients and preserving transplanted kidneys.
Methods and Materials: Twenty patients with PTLD were enrolled.  Immunosuppressive therapy was reduced or ceased, and Rapamycin was initiated at the time of PTLD diagnosis. We evaluated the effects of switching immunosuppressive drugs to Rapamycin on graft status, the response of tumor, and 6, 12 months, and 5-year survival in patients.
Results: PTLD remission was achieved in 14 patients, while six patients died; no relapse was detected in recovered patients. The median of PTLD free time was 25 months, and the mean overall survival in patients with PTLD treated by Rapamycin was 84.8 (95% CI=61.3-108.23).The five-year survival rate was 67%, 12 months survival was 73.8%, and six months' survival was 80%. The response rate to Rapamycin and immunosuppression reduction alone was 46.6%. Four out of 13 Diffuse Large B-Cell Lymphoma patients achieved a complete response just only after the reduction of immunosuppressive drugs and the consumption of Rapamycin.
Conclusion: The present study demonstrated the effectiveness of conversion from immunosuppressive medication, particularly of Calcineurin inhibitors to Rapamycin in PTLD patients. However, more research is needed to confirm the Rapamycin effect on patients with PTLD.

Published: October 2021

Background: Rapid maxillary expansion (RME) is the standard treatment for correcting lateral maxillary defects commonly used in orthodontics. It is the most effective approach to increase maxillary width in clinical practice. At present, there are few studies on the level of molecular biology of periodontal tissue remodeling during RME. We aimed to investigate changes in matrix metalloproteinase (MMP)-8, interleukin (IL)-6 and tumor necrosis factor (TNF)-αin gingival crevicular fluid during RME.
Methods: Patients admitted to Department of Stomatology, the Third Affiliated Hospital of Qiqihar Medical University, Qiqihar, Heilongjiang Province, China between Dec 2016 and Dec 2018 were enrolled, and randomly divided into the observation group (76 cases) and control group (62 cases). Periodontal clinical indicators were recorded. Gingival crevicular fluid was collected and the periodontal clinical indicators were recorded. The levels of MMP-8, IL-6 and TNF-α were determined by ELISA, and the contents of the two groups were compared.
Results: The plaque index of the observation group was significantly higher than that of the baseline T0 (P< 0.05) from T4, and the increase in the control group started from T5. The general clinical data of the two groups showed that the white blood cell count of the observation group was higher than that of the control group. The levels of MMP-8, IL-6 and TNF-α were the highest at T2, followed by T3, and gradually decreased at T4, and T5, and the differences were significant (P<0.05).
Conclusion: The changes in levels of MMP-8, IL-6 and TNF-α in adolescent patients during RME were related to the remodeling of periodontal tissue after RME.

Authors: Jang Ae Ri , Moon Jeong Eun
Published: October 2021

Background: Nursing educators commonly adopt simulations to educate nursing students and evaluate their clinical thinking, clinical reasoning, and clinical judgment. We aimed to determine the effectiveness of established nursing care simulations by evaluating, through video, a select number of nursing students in scenarios that simulate nursing care for Increased Intracranial Pressure (IICP) patients.
Methods: The participants were students in their senior year at a nursing college in South Korea in 2018. We adopted a mixed-method design by first conducting a nonequivalent control group pre-test/post-test research design, then analyzing the experimental group’s simulation videos. The participants consisted of 38 students in the experimental group and 39 students in the control group, and each group consisted of 9 teams. This study measured the level of anxiety (Cronbach’s α=0.780), critical thinking (Cronbach’s α=0.895), performance (Cronbach’s α=0.927), theoretical knowledge (Cronbach’s α=0.970), and analyzed clinical judgments by directly reviewing video from the experimental group. We used a mixed methods appraisal tool (MMAT) version 2018 as its research checklist.
Results: Confidence (P=0.000), theoretical knowledge (P=0.000), clinical performance (P=0.017) indicated statistically significant increases in the experimental group. We subsequently identified 10 clinical judgment processes, including “Identify the patient’s condition” to “Reassess the condition after symptoms improve” by analyzing the simulation videos.
Conclusion: Developing a simulation for nursing care is effective in honing students’ clinical judgment and enhancing their theoretical knowledge, confidence, and clinical performance.

Published: October 2021

Background: Graft and patient survival are of great importance after transplantation. This study aimed to determine the long-term survival rate of kidney transplantation and its effective factors among transplanted patients in Mashhad transplantation centers in northeastern Iran.
Methods: Overall, 618 kidney transplant recipients were examined in different transplantation centers during the years from 2000 to 2015 in a historical cohort study. The Kaplan-Meier method and the Log-rank test were used to calculate the survival rate of the kidney transplant, and to check the difference between survival curves respectively. Modeling of effective factors in survival rate was performed using Cox regression model.
Results: Overall, 1, 3, 5, 7, 10, and 15-year survival rate of kidney transplantation were 99%, 98%, 97%, 93%, 88 and 70% respectively. The adjusted hazard ratio indicated that variables such as recipient age >40 yr [HR=0.22, 95% CI=(0.071,0.691)], serum creatinine after transplantation >1.6 Mg/dl [HR=3.03, 95% CI=(1.284,7.125)], history of hypertension [HR=6.70, 95% CI=(2.746,16.348)], and BMI [HR (normal weight versus underweight)=0.26, 95% CI=(0.088,0.761), HR (over weight versus underweight)=0.13,95% CI=(0.038,0.442)] were significant factors on kidney transplant survival rate.
Conclusion: The short-term transplant survival rate was good in transplant patients. What's more, through a consideration of variables such as age, creatinine serum after transplantation, history hypertension and body mass index, as well as proper planning to control their effect, it is possible to improve the long-term graft survival rate.

Published: October 2021

Background: Ticks are forced vertebrate ectoparasites, including humans, and are vectors of serious diseases such as Crimean Congo Hemorrhagic Fever, Relapsing Fever, and various forms of encephalitis. Spatial assessment of the prevalence of ticks and detection of high risk areas for tick-borne disease transmission and evaluation of ecological measures are key aims of this research.
Methods: Ticks were collected using standard methods from 27 villages in the region of Sarab County in north-eastern Iran during the four seasons of 2018–2019 and identified using valid keys. The calculations of indices for biodiversity were based on the Margalef index, Shannon-Weiner index and Simpson index. R2.15 Statistical software was used for statistical analysis of indices of biodiversity, and ArcMap10.4.1 software, IDW and GeneralG methods were used. Analysis were used to investigate spatial distribution and to determine important tick hotspots.
Results:  A total of 2500 animals surveyed, 35% of them were infected. In total, 1416 ticks were caught, 74.6 %, 23.9% and 1.4 % were adult, nymph and larvae respectively. 94% of the ticks were hard ticks including 6 genera. According to the Margalef diversity index, the highest species biodiversity was related to summer (1.4234), and the lowest was relat­ed to winter (0.7379),
Conclusion: Large hotspot area was found in the central part of the study area. The area of study was very prone to tick-borne disease transmission in terms of tick diversity and tick species richness. Tick-borne disease control is an im­portant measure.
Meat quality, biosecurity, and animal welfare: consequences of an inefficient inspection
Authors: Tatemoto Patricia , Santos Oliveira Vanessa Louise , Vey da Silva David Attuy , Costa Almeida Marco Túlio
Published: October 2021

In livestock, biosecurity, animal welfare and meat quality have a synergetic effect on the final product. To meet minimal safety and humane production, it is necessary to consider biosecurity risks and procedures to mitigate animal welfare problems. Following guidelines to achieve it, the meat quality improves consequently. Here we tested two parameters regarding the meat quality of beef cattle to understand how the poor inspection affects the quality of the final product. Therefore, 12 samples of the longissimus dorsi muscle were evaluated from different butcheries, using fresh meat recently received by the supplier. There were no sanitary inspection records related to the sampled meat. The results showed a large percentage of PSE (pale, soft, and exudative) and DFD (dark, firm, and dry) meats. Given the pH and color values, it is concluded that the slaughtering was not carried out properly. Hence, technological defects in the meat were observed, making it inappropriate for consumption. We concluded that inefficient pre-slaughter handling is compromising animal welfare, increasing the biosecurity risk, and impairing the quality of the final product. We argue that these problems not only decrease the sustainability of livestock systems, but also compromises human health. Currently, livestock plays an important role in global environmental concerns, such as climate change, land degradation, water pollution and biodiversity loss. Then, it is needed to reduce the waste of such products.
Psychological and socio-economic challenges faced by teen fathers: A narrative review
Authors: Rantho K. M. , Matlakala F. K.
Published: October 2021

Purpose of the study: The purpose of the study was to explore the psychological and socio-economic challenges faced by teen fathers.

Methodology: This was a narrative literature review study, wherein researchers relied on secondary data from peer-reviewed published articles. Published articles were purposively sampled from different search engines such as Google scholar, South African National ETD portal, Jstor, Sabinet and EBSCOhost. The selection criteria were also determined by restricted data from the year 2003 to 2020 with a 17 years’ projection. The collected data was analysed thematically.

Main Findings: The study found that teenage boys are not immune to the challenges of parenthood. More like their counterparts, teen fathers experience psychological and socio-economic challenges as far as parenthood is concerned.

Application of the study: The lack of research on teen fathers creates an imbalance and leads people into believing that only teen mothers experience parenthood challenges. However, this study underpins that due to the lack of research on teen fathers, teen fathers experience various social ills such as stealing and dropping out of school due to the challenge of parenthood. 

Novelty/Originality of the study: This study contributes positively to the arena of social service and assists social workers with guidelines to address teen fatherhood. By the virtue of their educational background, social workers can advocate for voiceless teen fathers and challenge the imbalances that invade their dignity and manhood.

Authors: Tarconish Emily , Taconet Ashley , Gelbar Nicholas , Madaus Joseph , Dukes III Lyman , Faggella-Luby Michael
Published: October 2021

The two laws primarily governing disability services in postsecondary education, the Americans with Disabilities Act Amendments Act (ADAAA) and Section 504 of the Rehabilitation Act of 1973, permit institutions of higher education to determine disability documentation requirements on an individual basis. Many institutions have utilized documentation guidelines delineating a range of domains to be addressed, and often, suggestions for specific tests to be included, as well as strict recency requirements. Following passage of the ADAAA in 2008, the Association on Higher Education and Disability (AHEAD) published documentation guidance practices that reflected the updated ADAAA. The current qualitative study examined the perspectives of 12 directors of disability services (DDS) at postsecondary institutions in the United States regarding the disability documentation requirements at their respective schools and their perspectives on why the standards were adopted. Findings revealed a wide spectrum from flexibility to rigidity in requirements from those who employ traditional guidelines to those who apply selective degrees of the AHEAD guidance. Benefits and drawbacks of documentation and the AHEAD guidance are discussed, as well as suggestions for practitioners and institutions seeking to implement the AHEAD guidance.

Published: October 2021

The article considers a novel parallel mechanism with drives located on the base at different angles to its plane. This arrangement allows performing a relative movement between objects under water or in space (in aggressive environments). The new mechanism topology is compact for transportation and efficient for operation in aggressive environments. Structural synthesis has been performed; the number of degrees of freedom of the output link was calculated. A general approach to solving the inverse kinematics problem of positions is proposed and an example for a kinematic chain is shown. Denavit — Hartenberg matrices are used to solve the problem of positions. The position of the output link described by this matrix is used to represent the points of this link in the base coordinate system. The constraint equations are applied, which are the distances between the points of the base and the output link.

Authors: Marenina L.N. , Galerkin Y.B.
Published: October 2021

Calculations performed with modern computer fluid dynamics (CFD) programs aid in optimizing the flow path of a centrifugal compressor. The characteristics of the stator elements of the flow path, calculated by CFD methods, are considered to be quite accurate. Optimization of three-stage reverse-directing devices with a large flow rate (0.15) and different theoretical head coefficients (0.45; 0.60; 0.70) has been carried out. For optimizing return channels a parameterized model was created. Optimization was performed with MOGA (Multi-Objective Genetic Algorithm) optimization method in the Direct Optimization program of the ANSYS software package. The optimization goal was to achieve the minimum loss factor at the design point. In the optimization process, the following parameters were varied: the number of and the inlet angle of the vanes, the height of the vanes at the inlet, external and internal radii of curvature of the U-bend. For the return channel with a minimum loss coefficient, the dependences of this parameter on the flow coefficient were calculated. Comparison with the characteristics of the initial variant showed that the optimized return channels are more efficient over the entire flow range. Optimization allowed reducing the loss factor by 20%.
Recurrent-iterative algorithm for control synthesis of spacecraft terminal reorientation based on the method for analytical design of optimal controllers
Authors: Pushkar O.D.
Published: October 2021

The paper considers the application of the method for analytical design of optimal controllers as formulated by of A.A. Krasovsky (optimization according to the criterion of generalized work) for the control synthesis of spacecraft reorientation from an arbitrary angular position to a given attitude during a fixed time period. A predictive algorithm model was selected as a numerical implementation for the analytical design according to the generalized performance criterion. In order to investigate the angular motion optimization methods experimentally, a model of the spacecraft reorientation control process was developed and implemented in C#. Numerical experiments demonstrated that the generic algorithm does not ensure the specified accuracy of the final orientation, and an increase in the weight coefficients in the terminal member in order to reduce the orientation errors leads to a loss of stability of the dynamic process. The paper proposes a modification of the prediction algorithm — a recurrent-iterative algorithm for exact reorientation of a spacecraft in a fixed time period. The approach used in this case involves organizing an iterative procedure for synthesizing the optimal control of the spacecraft reorientation based on a prediction algorithm. The optimal control calculated at each iteration is used at the next step of the iterative procedure as the next additive component of programmable control. Numerical experiments demonstrated that the recursive-iterative method for reorienting a spacecraft ensures the angular motion stability of the spacecraft and the specified accuracy of the final orientation in a wide range of boundary conditions. The scope of the proposed algorithm is limited to control objects with continuum end-effectors. An example of such a control object is a remote sensing satellite with power gyroscopes (gyrodines) in the orientation system.

Published: October 2021

The article researches the effect of five cycles of heating to a temperature of 1000 °C and two cycles of heating to a temperature of 1100 °C on the structure of a layered composite material consisted of 100 alternating layers of 08kp and 08Kh18N10 steels (one layer thickness is ~22 μm). As a result of the nickel and chromium diffusion during thermocycling, the thickness of the layers changed and an interlayer with a structure different from the structure of neighboring layers was formed. Heating to 1100 °C also has led to a partial disarrangement of the layered material structure. It was found that the real diffusion path of alloying elements during heat treatment significantly exceeds the calculated one, and chromium atoms are redistributed between the layers of the material much more actively than nickel atoms.

Syncope is defined as a transient loss of consciousness due to cerebral hypoperfusion, characterized by a rapid onset, short duration, and spontaneous complete recovery of all vital functions without signs of neurological deficits. Syncope is a multidisciplinary medical problem common in clinical practice. As a rule, syncope occurs due to cardiovascular dysfunction of organic or functional origin, which either develops spontaneously or is induced by a trigger. Due to a various etiology differential diagnosis and prognostic evaluation is difficult. This clinical case demonstrates the features of differential diagnosis of vasovagal syncope in a patient with polymorbid pathology and the features of the choice of an adequate management, including recommendations for lifestyle modifications, specialized education regarding prodromal symptoms recognition methods and timely application of countermeasures.

This study aims to detect antibiotic genes in endophytic bacteria that can suppress cocoa black pod disease. Methods: Eight endophytic bacteria were isolated from healthy cocoa pods and twigs that showed potentials in suppressing P. palmivora growth in vitro were used in suppressing of black pod rot disease in vivo tests. Antibiotic biosynthesis-related genes from eight endophytic bacterial isolates were confirmed by using PCR method, which includes phenazine-1-carboxylic (PCA), pyrrolnitrin (PRN), phenazine-1-carboxamide acid (PCN), pyoluteorin (PLT) and 2,4-diacetylphloroglucinol (DPAG/Phl). Result: The endophytic bacteria, 4RSI, 5BR B3 and 2RW B2 isolates showed the highest disease suppressing index to black pod rot disease in vivo, i.e., 70.27%, 70.08% and 56.64%. The isolates 5BR B3 and 2RW B2 DNA yielded PCR product by using PCA primers (1400 bp), PRN primers (700 bp) and DAPG primers (1600 bp), while the 5RSI isolate yield PCR product using PRN primers only. Endophytic bacterial isolates 5BRB3 and 2RW B2 provided partial disease suppression to pod rot disease by inhibit pathogen growth and antibiotic compounds production.

Background: There is little information on the effect of interaction between grazing intensity and nitrogen fertilization on the productive characteristics of ryegrass (Lolium multiflorum Lam). The objective of this work was to evaluate the effect of grazing intensity and nitrogen fertilization on the productive characteristics of ryegrass pasture in a crop-livestock integration system. Methods: A randomized complete block experimental design with a 2 × 2 × 5 factorial arrangement was used, with three replications. The study factors were two management grass heights, low height (LH = 10 cm) and high height (HH = 25 cm), two different nitrogen fertilization times (NP = nitrogen applied to pasture and NG = nitrogen applied to grains crop) and five evaluation periods. Result: The forage mass was higher at higher handling heights and with lower stocking rate (HH = 3995 kg DM ha-1). The forage density tended to be higher in the plots with lower grass height and nitrogen fertilization (LH = 193.5 and NP = 184.7 kg DM ha-1 cm-1). The highest accumulation rate (AR) and forage production (FP) was observed in managed pastures with HHNP (AR = 120.4 kg DM ha-1 day-1; FP = 18471 kg DM ha-1). The management of grass with HHNP provided higher forage mass, higher accumulation rate and higher dry matter production in ryegrass pasture, due to an adequate stocking rate.

İskender’i Kandıran Şeytan Hikâyeleri ve İskendernâme Literatürü
Authors: KOCAER Sibel
Published: October 2021

İskender ile ilgili hikâyeler, yazın geleneklerinin yazmalar aracılığıyla şekillendiği çağların farklı diller arasında dolaşan ortak hikâyeleri arasında en çok tanınanlar arasında yer alır. Bu hikâyeler, yüzyıllar boyunca kopyalanarak, çeşitli dillere çevrilerek, yeniden kurgulanıp yazılarak ve sözlü olarak aktarılarak farklı coğrafyalara yayılmıştır. Bu makalenin odağında Hamzavî’nin İskendernâme’si vardır. Hikâyeleme kısmı çoğunlukla mensur yazılmış olmasına rağmen çok sayıda manzum parça içermesi nedeniyle mensur – manzum karışık bir eser olarak tanımlanan bu İskendernâme, çok sayıda ciltten oluşan hacimli bir eserdir. Bu makale kapsamında incelenen nüsha British Library’de (Londra) bulunan Or 11056 arşiv numaralı ve 1435/36 (839) istinsah tarihli nüshadır.
Bu makalenin konusu, British Library nüshasında birçok kez tekrar eden İskender’in şeytanla karşılaştığı hikâyelerdir. Şeytanın farklı suretlerde İskender’in karşısına çıkarak onu kandırdığı birbiriyle bağlantılı bu hikâyeler, hem diğer Türkçe İskendernâmelerde yer almaması hem de İskender’in portresine farklı özellikler katmasıyla dikkat çeker. Bu hikâyelerin on beşinci yüzyılda dolaşımda olan Arapça ve Malayca yazılmış iki ayrı İskender biyografisindeki varlıkları ise üç ayrı dil ve kültüre ait bu üç nüsha arasındaki metinsel bağlara işaret eder. Bu nedenle, Firdevsî, Nizâmî ve Ahmedî’den farklı bir tarz ve içerikle Hamzavî’nin biçimlendirdiği İskender portresi, kendi özgü özellikleri ile Anadolu’daki İskendernâme geleneğini tanımlamak için ve farklı dillerdeki İskender biyografileri arasındaki metinsel bağların izini sürmek için önemli ipuçları içermektedir.
Оценочное исследование влияния радиоизлучения вышек-ретрансляторов мобильной связи на здоровье людей

Присутствие большого количества вышек-ретрансляторов мобильной связи на крышах зданий в городах поднимает ряд вопросов о возможном влиянии электромагнитного ВЧ-излучения EMF (electromagnetic frequency) и спектральной плотности мощности PSD (power spectrum density) на население даже тогда, когда вышки установлены в городах в соответствии с действующими правилами и стандартами. Цель этой статьи попытаться ответить на эти вопросы путем измерения EMF от локальных вышек-ретрансляторов, построенных в небольшом городе Эль-Кут (Al-Kut) в Ираке. Эта работа исследует влияние электромагнитного излучения от вышек-ретрансляторов мобильной связи на здоровье людей, и на то, как это излучение влияет на иммунитет человека к болезням. Практические измерения получены с помощью измерителя электромагнитного поля и глобальной системы позиционирования GPS и представлены посредством географической информационной системы GIS (geographical information system). В работе выбраны две группы для исследования. Первая группа проживет в районе с тремя вышками, установленными на расстоянии 50–100 м друг от друга. Вторая группа проживает в районе, где вышки установлены за границами этого жилого района на расстоянии более 500 м. Полученные результаты показали, что первая группа страдает от проблем со здоровьем в значительно большей степени, чем вторая группа. Кроме того, высокий процент жилья здесь занимают наиболее образованные и менее осведомленные о влиянии EMF излучения при долгосрочном его воздействии. Этот факт можно объяснить недостатками учебного плана. Таким образом, это исследование рекомендует объединять экологические концепции в правительских учреждениях и организациях для всех взрослых, независимо от их образования, для повышения осведомленности людей в этой области.

O objetivo do trabalho foi selecionar equações volumétricas para clones de GG-100, VM-58 e seminal de Eucalyptus, em Aliança, sul do estado do Tocantins. Os dados foram coletados em plantio de Eucalyptus, com 7 anos de idade com espaçamento de 2,5m x 4,0m (1.000 árvores/ha). A seleção das árvores para a cubagem foi realizada a partir de inventário florestal sistemático e estratificado por clone e seminal para posterior determinação da distribuição diamétrica. A cubagem foi feita pelo método de Smaliam em 48 árvores com DAP ≥ 12 cm até contemplar toda a distribuição diamétrica. Foram ajustados 10 modelos matemáticos tradicionais para cada espécie de eucaliptus. Os melhores modelos ajustados para cada espécie foram determinados através através dos valores de R2aj e CV (%) juntamente com a análise gráfica de resíduos. Os melhores modelos foram:   (Schumacher Hall) para VM-58 tendo o R2aj =0,88 e  CV% =5,00, o modelo    (Husch) para GG-100 com o R2aj= 0,77 e o CV%= 34,89 e   (Schumacher Hall) para Seminal, com o R2aj= 0,91 e o CV%= 10,12. Através do teste tukey, não foi observada diferença significativa nas variáveis DAP e volume entre os clones.

Authors: Sudah Suleiman , Nasra Matthew , Michel Christopher , Dijanic Christopher , Kerrigan Daniel , Curatolo Evan
Published: October 2021

Case:

A 12-year-old boy sustained a patella sleeve fracture of the superior pole, medial patellofemoral ligament tear, and lateral femoral condyle fracture after a direct contact sledding injury. He was managed nonoperatively with 5 weeks of cylinder cast immobilization with transition to a hinged knee brace and physiotherapy. By 3 months, he returned to sport activity without patellar instability.

Conclusion:

This is the first case to describe simultaneous development of these 3 injuries in an adolescent. We recommend that patients with patella sleeve fracture undergo magnetic resonance imaging to assess for local soft-tissue injury because this may influence treatment decisions.

Published: October 2021

Case:

A 68-year-old woman with a history of stage IIIC (T3bN1bM0) melanoma with metastases to her right axilla status after 10 cycles of nivolumab presented with right shoulder pain. Radiographs showed a progressive erosive glenohumeral joint lesion. The workup was negative for metastasis and infection. Her clinical and radiographic findings were consistent with erosive arthritis. The patient underwent shoulder hemiarthroplasty and experienced substantial improvements.

Conclusion:

This is an unusual case of inflammatory arthritis associated with nivolumab, an antiprogrammed cell death protein 1, and is an important reminder of the musculoskeletal toxicities associated with immunotherapies.
