Published: July 2022

Abstract: Cryptosporidiosis is one of the most important zoonotic parasitic diseases affecting a wide range of host species. The disease is widely distributed all over the world. Cryptosporidium species can affect different avian hosts, causing severe economic losses. The severity of avian cryptosporidiosis symptoms vary from asymptomatic disease to severe enteric and/or respiratory manifestations with high mortality. Diagnosis of Cryptosporidium infection is mainly based on microscopic detection of oocysts, serological methods, or molecular techniques to identify different Cryptosporidium species. Humans and animals are highly susceptible to infection by different Cryptosporidium species as a result of the ingestion of contaminated food and water by oocysts or direct contact with infected hosts. Different prevention and control strategies have been applied either in the surrounding environment or for the infected animals, birds, and humans. Therefore, this review article was designed to shed light on avian cryptosporidiosis species and its distribution, susceptibility and infection, clinical pictures, laboratory diagnosis, zoonotic importance in humans, and prevention and control strategies.Key words: avian; control; Cryptosporidium; diagnosis; humanKRIPTOSPORIDIOZA PTIC: POMEMBNA PARAZITSKA BOLEZEN, NEVARNA ZA JAVNO ZDRAVJEIzvleček: Kriptosporidioza je ena najpomembnejših zoonotskih parazitskih bolezni, ki prizadene številne gostiteljske vrste.

Three-Dimensional Nonlinear Dynamic Analysis of Base Isolated Cylindrical Steel Tank
Authors: Saria Abdellali , Djermane Mohamed , Hadj-Djelloul Nasser Dine
Published: July 2022

Failure of a tank during an earthquake can result in significant financial, human, and environmental losses. Thus, their lack of resiliency against strong earthquakes may result in refinery disruption. This has the potential to have a considerable impact on any economic system. As a result, more research into the seismic performance of tank structures is required to attain the highest possible level of resistance against strong earthquakes. In this paper, we aim to look into the installation of seismic isolation systems in cylindrical steel storage tanks. A nonlinear 3D finite element model is developed with ANSYS software. Moreover, tank wall material nonlinearity, fluid-structure-interaction, and sloshing components are considered. The bilinear hysteretic LRB is used for modal and time-history analysis. In this work, three tanks with varying aspect ratios are studied: "Model A", "Model B", and "Model C". Furthermore, the fixed tank's fundamental frequencies were compared to the analytical results of the American API 650 Standard. Subsequently, the dynamic behavior response of the researched tanks to the horizontal component of the El-Centro 1940 earthquake with PGAs of 0.34g and 0.5g is investigated. As a result, the dominating frequency of the seismic isolation system is within the effective frequency range of seismically isolated systems. The results illustrate that the base isolation limits the tank wall movement with a large displacement in the isolators; the mode shape is a cantilever beam in all isolated circumstances. The total seismic response reduction in the slender tanks is greater as compared to the broad case in the base-isolated tanks. The sloshing displacement increases with an increase in the tank aspect ratio. Additionally, the isolation device eliminates tank buckling at the base and top of the tank shell during seismic excitation (elephant foot and diamond buckling). It can be concluded that the seismic isolation technique has a more significant impact on reducing the dynamic response of ground-supported tanks, particularly in taller tanks as compared to broad tanks. Doi: 10.28991/CEJ-2022-08-06-013 Full Text: PDF

Authors: Abbas Hayder Qays , Al‐Zuhairi Alaa Hussein
Published: July 2022

The study presents the performance of flexural strengthening of concrete members exposed to partially unbonded prestressing with a particular emphasis on the amount (0, 14.2, and 28.5%) of cut strands-symmetrical and asymmetrical damage. In addition to examining the influence of cut strands on the remaining capacity of post-tensioned unbonded members and the effectiveness of carbon fiber reinforced polymer laminates restoration, The investigated results on rectangular members subjected to a four-point static bending load based on the composition of the laminate affected the stress of the CFRP, the failure mode, and flexural strength and deflection are covered in this study. The experimental results revealed that the usage of CFRP laminates has a considerable impact on strand strain. In addition to that, the flexural stiffness of strengthened members becomes increasingly significant within the serviceability phases as the damaged strand ratios increase. The EB-CFRP laminates increased the flexural capacity by approximately 13%, which corresponds to strand damage of 14.28% and about 9.5% for 28.57% of strand damage, which represents one of the unique findings in this field. Additionally, semi-empirical equations for forecasting the actual strain of unbonded tendons were presented. The suggested equations are simple to solve and produce precise results. Doi: 10.28991/CEJ-2022-08-06-014 Full Text: PDF

Published: July 2022

La verminosis pulmonar en ovinos y caprinos es una de las parasitosis más importantes que afectan a ambas especies. Es causada por los nematodos Dictyocaulus filaria, Protostrongylus rufescens y Muellerius capillaris. El objetivo de este trabajo fue presentar información reciente sobre verminosis en ovinos y caprinos. Su patogenicidad depende de la cantidad de larvas presentes y su ubicación en el parenquima pulmonar, lo que puede provocar una bronconeumonía, que en ocasiones es mortal. La enfermedad puede ser clínica o subclínica, con signos como tos, taquipnea, secreción nasal y retraso en el crecimiento. El diagnóstico se puede realizar mediante detección de larvas del primer estadio (L1) en heces, utilizando la técnica de Baermann. Para el tratamiento se pueden utilizar benzimidazoles, lactonas macrocíclicas e imidazotiazoles. A pesar de la poca importancia que se le suele dar como verminosis pulmonar, puede provocar afectación a los parámetros productivos y disminuir la ganancia de peso, así como, predisponer a bronconeumonías secundarias, afectando la rentabilidad de las unidades de producción.

If there is any whether it has become a guarantee for the smooth development of early childhood psychically is not just in material fulfillment. This study is a study that uses qualitative methods that refer to earlier sources of libraries and researches that support library data. With the normative description approach of positf hocumes relating to child rights and obligations. The results of the study showed that in the rule of the positive Law in Indonesia still only generally redaction of the guaranteed needs of child psychic development. What’s more, regarding the child who was a victim of divorce, but at least in article 156 The Islamic Law Compilation of point C could already be a solution in the event of a problem.

Logistic model tree (pohon model logistik) adalah metode pemodelan nonparametrik yang mengombinasikan metode pohon keputusan dengan regresi logistik linier. Pohon model logistik dapat menangani multikolinearitas dengan baik, tetapi tidak kebal terhadap masalah yang diakibatkan oleh ketakseimbangan data. Penelitian ini dilakukan untuk mengkaji performa metode penanganan ketakseimbangan data undersampling, SMOTE, dan ROSE pada pohon model logistik. Data yang digunakan adalah data simulasi yang diperoleh dengan membangkitkan bilangan acak berdasarkan sebaran Bernoulli sebagai peubah respon dan bilangan normal berganda dua peubah sebagai peubah penjelas. Kombinasi yang digunakan adalah tingkat ketakseimbangan data. Berdasarkan nilai AUC, diperoleh bahwa pohon model logistik yang dibangun dengan menerapkan metode penanganan ketakseimbangan data memiliki performa klasifikasi yang lebih baik dibandingkan dengan pohon model logistik yang dibangun tanpa menerapkan metode penanganan ketakseimbangan data pada seluruh tingkat ketakseimbangan yang dicobakan. Pohon model logistik dengan penerapan metode ROSE memiliki performa lebih baik dibandingkan dengan pohon model logistik dengan penerapan metode undersampling maupun SMOTE pada gugus data dengan tingkat ketakseimbangan data tinggi hingga sedang. Pada gugus data dengan tingkat ketakseimbangan data rendah, performa pohon model logistik dengan penerapan metode ROSE dan metode undersampling tidak berbeda signifikan.

Aim: Boehler angle and Gissane angle was aimed to determine in Turkish population aged between 18-79 years. Materials and Methods: It is a retrospective study Boehler angle and the Gissane angle measurements were obtained from lateral ankle-foot radiographs taken from 236 healthy population. Results: The significance wasn’t found in both two angle parameters between gender (p=0.283 for the Boehler angle; p=0.485 for the Gissane angle). Additionally, according to age groups, there was a decrease in Boehler angle from decade 1 to the decade 7, the Boehler’s angle increased again. Also, the Gissane angle reached a maximum degree in the decade 7, whereas the lowest value obtained in the decade 2.Conclusion: There were a difference in calcaneal angle reference values in terms of gender, race and age. The knowledge of the calcaneal angles reference values can provide an important data for clinicians, radiologist and orthopedists with reference and normal values for healthy population.
Post-translational modification of protein and disease onset- recent advances

Published: July 2022

Proteins are the basis of cellular and physiological functioning in living organisms, and the physical and chemical properties of proteins dictate their activities and functions. The primary sequence of a protein is a main determinant of protein folding and final conformation as well as biochemical activity, stability, and half-life. Post-translational modifications (PTMs) are biochemical alterations of amino acids that extend the functional repertoire of proteins. PTMs regulate structural confirmations of proteins, protein-protein interactions and cellular signal transduction central in development. Alterations in the rate and extent of protein synthesis, accuracy, PTMs, and protein turnover are among the major molecular characteristics of some diseases. In this review, the incidence of PTMs disruption on certain disorders was evaluated.

Introduction: LBP is the most common cause of activity restriction and work absence in much parts of the world, putting a heavy financial burden on people. This study aims at determining the prevalence and exposure to risk factors associated with low back pain (LBP) among commercial bike riders within Nnewi-North Local Government Area of Anambra state. Methodology: This was a cross-sectional study that involved commercial motorcycle riders that ply within the four major villages of Nnewi town in Nnewi-North local government area of Anambra state. An interviewer based semi-structured questionnaire was administered to the respondents at their muster points. Results: One hundred and fifty-four riders were recruited and all were male. The prevalence of LBP was 25%. LBP was highest among riders between ages of 26-36years. There was significant association linking age and marital status to low back pain (LBP) with p-values of 0.001 and 0.013 respectively. Conclusion: Our findings suggest that low back pain is very common among this population and has led to both mild, moderate and severe functional disabilities to the riders. This study also demonstrated the exposure of the riders to some risk factors of LBP. Adequate public awareness, education and use of ergonomics would help in the reduction of this problem.
