Jejunal Hemolymphangioma in a Patient Presenting with Gastrointestinal
Bleeding
Authors: Shao Xiao-Dong , Wang Le
Published: August 2021

Background:

Hemolymphangioma is rarely found in the small intestine. There have only been eight reports of hemolymphangiomas arising in the small intestine to date. The first patient was reported by Fang et al. in 2012. A small intestinal hemolymphangioma may lead to anemia and gastro-intestinal bleeding.

Case Presentation:

We report a case of jejunal hemolymphangioma in a 49-year-old man. The patient presented with melena and anemia. He underwent double balloon enteroscopy (DBE) the antegrade approach, which demonstrated a 3.0 cm segment of jejunum with nearly 75% of the circumferential lesion with blood remnant. The raised soft lesion was in the middle of the jejunum with white patches on the surface of the mucosa. Endoscopic biopsy was not performed to avoid secondary bleeding. The patient underwent laparotomy, and partial small intestine resection was performed. A 5.0cm segment of jejunum was resected with primary anastomosis. The patient had an uneventful postoperative recovery. Macroscopic pathological examination showed a cavernous, soft and compressible tumor. Microscopic examination showed a tumor which was composed of blood and lymphatic vessels mainly located in the submucosa. The definitive histological diagnosis was jejunal hemolymphangioma. During a follow-up of 2 years, there was no further gastrointestinal bleeding.

Conclusion:

Small intestinal hemolymphangioma is a rare benign tumor of which clinical manifesta-tions are nonspecific and accurate preoperative diagnosis is challenging. Endoscopic biopsy is not rec-ommended for hemolymphangioma of the gastrointestinal tract due to the risk of severe bleeding. Com-plete surgical resection of the hemolymphangioma is considered the most effective treatment for small intestinal hemolymphangioma.

The study of exhaust H2S and NO2 gases using activated carbon has been conducted. In this study, activated carbon was prepared from mendong plant (Frimbistylis umbellaris), which was activated using zinc chloride (ZnCl2) with concentrations of 2.5; 5; 7.5; and 10 % w/v to determine the efficiency of H2S adsorption. Mendong charcoal was obtained from the process of using a modified tool. Activation was done by maceration using ZnCl2 activator (w/v) for 24 hours. The adsorption of H2S and NO2 was analyzed using UV-Vis spectrophotometry. Determinations of H2S gas carried out using the blue methylene’s method for 1 hour showed the highest effectiveness of mendong activated carbon was of that at the concentration of 2.5 % ZnCl2 w/v with 80% of H2S removal. Further, the mendong activated carbon with the concentration of 2.5% ZnCl2 w/v was used for NO2 adsorption. The adsorption of NO2 gas was conducted for 1 hour using Griess Saltzman’s method. The result showed that the largest concentration of NO2 gas was adsorbed when the HNO3 concentration was 1.5 M (0.057 µg/mL). The percentage of NO2 efficiency adsorbed was at 28%.

This study aims to determine the effect of sea sand modification with SDBS for adsorption of Fe3+. Sea sand was treated with 0.1 M HCl solution at 25oC. Organo-quartz was prepared at SDBS concentration of below, equal, and above the CMC value by shaking the mixture for 4 hours at 100 rpm. Characterization by FTIR spectrophotometry showed a change in the spectra pattern. The activation caused increasing of -OH silanol while modifications make them decrease. Characterization with SEM showed that the morphology of the sea sand was not uniform with irregular white chunks. The EDX results showed that the dominant elements were C (13.89% ± 10.86), O (40.48% ± 6.58), Si (16.51% ± 8.13), and Fe (11.68% ± 14.38). Adsorption was carried out using Fe3+ at 50 ppm. The Fe3+ analysis was conducted by AAS. The adsorption value by activated sea sand was 58.22% ± 7.23% whereas without treatment sea sand was 70.46% ± 5.54, and the modified sea sand was 53.24% ± 4.86. The lower adsorption is probably caused by the dissolved iron oxides in sea sand during activation.

The increase of pathogens in milk is threatening for the human beings. This is an investigation on overall microbiological analysis of raw and pasteurized milk as well as the milk-based beverages and also determining the antibiotic resistance pattern of isolated Escherichia coli and Staphylococcus aureus. A total of 100 samples (raw milk, pasteurized milk, mattha, lassi and laban) were taken from various locations of the capital city of Bangladesh, Dhaka. Total Viable Count, Total Coliform Count and Yeast and Moulds Count were performed as the microbiological inspection of selected samples. E.coli and Staphylococcus aureus were identified by conducting morphological analysis, gram-staining and biochemical tests. Antibiotic resistance pattern of isolated Escherichia Coli and Staphylococcus aureus were also detected with 11 commonly used antibiotics by conducting disc-diffusion method, following the CLSI guideline. The TVC range was the highest in raw milk samples (3.8×104 – 4.1×108 cfu/ml), and the lowest in pasteurized milk samples (1.2×102 – 5.4×103 cfu/ml), while 70% raw milk and 10% pasteurized milk samples strains were above the acceptable limit of Food and Drug Administration (FDA). Thirty-six Escherichia coli and thirty-two Staphylococcus aureus were isolated from all the 100 milk and milk-based beverage samples. The isolated Escherichia coli strains were most resistant to Penicillin G (81.58%), Erythromycin (78.94%) and Ampicillin (73.68%), and isolated Staphylococcus aureus strains were most resistant to Penicillin G (90.62%), Ampicillin (81.25%) and Methicillin (71.87%). respectively.

Group B streptococcus (GBS) is a common cause of infections in pregnant females and non-pregnant adults with chronic diseases (such as diabetes and cancer), also it is the main reason of septicaemia and meningitis in infants. The aim of this study was to figure out how common GBS is in pregnant women, the antimicrobial sensitivity pattern of the isolated GBS colonies and check the presence of scpB and rib virulence genes in these isolates. We screened 203 pregnant women attending the Maternity Hospital of Ain Shams University using vaginal sampling. Isolation was done on CHROMagarTM Strep B and sheep blood agar plates then identified via colony characters, Gram stain, test for catalase production, Christie–Atkins–Munch-Petersen (CAMP) test, test for hippurate hydrolysis and latex agglutination test. This was followed by an antibiotic susceptibility test. Finally, Detection of scpB and rib virulence genes by conventional PCR was done. Our study detected that the prevalence rate of GBS in involved pregnant women was 11.33%. A statistically significant association between colonization and history of spontaneous abortion and preterm labor was observed. CHROMagar™ StrepB showed the same sensitivity of sheep blood agar with extensive effort to isolate suspected GBS colonies from blood agar. GBS was 100% sensitive to levofloxacin, linezolid, cefepime, ceftaroline and ceftriaxone. Also, it was highly sensitive to vancomycin (91.3%). Sensitivity to clindamycin, azithromycin, penicillin and ampicillin was (21.70%, 21.70%,47.80%, 47.80%) respectively. The least sensitivity of GBS was to erythromycin ( 8.7%). All isolates possessed the scpB gene (100%) while only 18 isolates (78.26%) had the rib gene.

In generation, Most of the thermal power plant is installed ESP with Bag-house FF Filteration system. Electrostatic Precipitator (ESP) are well accepted and widely used for air pollution control due to reasonable collections efficiency, low pressure-drop, and low capital and operating costs. The performance of modern ESP’s would be expected to be better than 99.9% particulate removal efficiency while incurring less than 100 Pa pressure drop. The geometry of inlet duct has refined with guide vanes placed at several locations. An improvement of flow distribution in the duct through optimization can be achieved by modification of inlet duct. In this present work, CFD analysis of flow through the APH outlet to ESP inlet duct and ESP Outlet duct is performed by modification of duct , in order to reduce the pressure drop, reduce turbulence as well as achieve uniform distributions among the all streams and minimize erosion of duct walls caused due to high velocity. Reducing erosion of the duct walls results in the reduction of leakages in the ducts. Reduction of pressure drop across the duct saves the power consumption. The ESP inlet and ESP Outlet duct consists of two inlet and two outlets. The simulation studies involving the flow through the ESP inlet and outlet duct are performed using3-D Model development using Solid Works, ANSYS Design Modeler, Grid generation using ICEM CFD (HEXA) and Performing the simulation using ANSYS CFX using structured hexahedral mesh. The pathlines, velocity contours, pressure distributions for various cases involving without modification of duct.

Authors: Babu Chippy
Published: August 2021

Remote sensing image retrieval (RSIR) may be a fundamental task in remote sensing. Most content-based image retrieval (CBRSIR) approaches take an easy distance as similarity criteria. A retrieval method supported weighted distance and basic features of Convolutional Neural Network (CNN) is proposed during this letter. the strategy contains two stages. First, in offline stage, the pretrained CNN will be fine-tuned by some labelled images from our target data set, then accustomed extract CNN features, and labelled the pictures within the retrieval data set. Second, in online stage, we extract features of the query image by using fine-tuned CNN model and calculate the load of every image class and apply them to calculate the space between the query image and also the retrieved images. Experiments and methods are conducted on two Remote Sensing Image Retrieval data sets. Compared with the state-of the-art methods, the proposed method significantly improves retrieval performance.

Authors: Pranamya N. P.
Published: August 2021

A novel amino acid ligand derived from Benzilic acid and Tyrosine and its Cr (II), Fe (III), Co (II) and Ni (II) transition metal complexes were synthesized. The structure elucidation of the ligand and its complexes were derived on the basis of various spectroscopic methods such as Infrared and electronic spectra along with the aid of CHN, magnetic and conductometric measurements1, 2, 3. The corrosion inhibition efficiency of newly synthesized amino acid-mixed ligand and their metal complexes were studied in 0.5M HCl solution. The results show that the inhibitors exhibits an inhibition efficiency of 40-67% at 200ppm.The ligand shows the maximum efficiency whereas on complexation the efficiency tend to decrease. When the concentration of the inhibitor increases, then the efficiency of the inhibitor will increase4. The adsorption studies reveal that iron complex with the mild steel is chemisorption and the thermodynamic parameters such as adsorption, equilibrium constant (K) and free energy of adsorption (∆Gads) were calculated. The curve of the adsorption fits well with Langmuir adsorption isotherm.
Optimization of Shrinkage Porosity in Grinding Media Balls by Casting Design Modification and Simulation Technique
Authors: Rashid Abira
Published: August 2021

Shrinkage porosity or cavity are associated with the solidification of the metal either due to gas/air entrapment or when the shrinkage occurring during solidification is not entirely compensated by the riser. Shrinkage cavities occurring in the casting reduces its strength which leads to unfulfillment of the desired serviceability. In this paper, casting design has been modified using the DISA manual to achieve directional solidification which directly relates to improvement of casting quality. The running of metal from pouring basin into casting along with solidification has been analysed through PROCAST which is a casting simulation software based on Finite Element Method and CAFE (Cellular Automata Finite Element) Model. The feeding system of the casting has been modified in terms of shape and volume to minimize air aspiration effect and promote directional solidification. The model used is of grinding media balls casting of high chromium cast iron. The feeding pattern, feeding velocity and solidification with respect to pouring temperature, pouring rate, ambient temperature and film coefficient has been analysed. The final optimum range of all parameters with corresponding minimum shrinkage porosity in casting was obtained. Main aim was to minimize shrinkage porosity in the main casting, ignoring gating and feeding system. The actual minimization of shrinkage porosity comes out around 56 %.

A Review on Automatic Soil Classification in Digital Image Processing
Authors: Shivhare Shraddha
Published: August 2021

Soil classification is an essential piece of geology. However, many examinations have assessed the precision and consistency of the soil classification using various techniques. This examination starts by evaluating the verifiable advancement of soil classification science. The verifiable audit contextualizes the wordings and the speculations of soil development factors, which supported soil classification frameworks. This paper is intended to review some research papers on soil classification and analyze the limitations of implemented techniques by their parameters. In the age of digital world, it is beneficial to obtain the information from image without any hassle. Machine learning is an approach through which we can obtain the better level of accuracy and minimize the false alarm rate. But machine learning requires so many samples through which we can observe the correct precision that also requires much storage that may takes much processing time that reduces the feasibility of the system. We have to train a system with limited number of samples with high iterations that produces higher precision rate with minimal errors.

Security of any country as well as the whole world can be ensure through the conservation of germplasm since they are genetic resources that can be used to prolong a population of an organism. Plant genetic resources (PGR) are the foundation of agriculture as well as food and nutritional security. The ICAR-NBPGR is key institution at national level for management of PGR in India under Indian Council of Agricultural Research (ICAR), New Delhi. India being rich in both flora and fauna germplasm diversity also have challenge of protecting its natural heritage. At the same time, we also have mutually beneficial strategies for germplasm exchange with other countries. The National Bureau of Plant Genetic Resources (NBPGR) activities include PGR exploration, collection, exchange, characteri- zation, evaluation, conservation and documentation. It also perform the responsibility to carry out quarantine of all imported PGR. NBPGR collects and acquires germplasm from various sources, conserves it in the Genebank, characterizes and evaluates it for different traits and provides ready material for breeders to develop varieties for farmers. At present, the National Genebank conserves more than 0.45 million accessions. NBPGR is responsible for identifying trait-specific pre-adapted climate resilient genotypes, promising material with disease resistance and quality traits which the breeders use for various crop improvement programmes. The prime focus area of research of NBPGR at present is is on characterization of ex situ conserved germplasm and detailed evaluation of prioritized crops for enhanced utilization. identification of novel genes and alleles for enhanced utilization of PGR; identification and deployment of germplasm/landraces.

The focus in most research on leader integrity has been on its positive consequences; however, studies on the antecedents of leader integrity are still lacking. Drawing on moral disengagement theory, in this empirical study we examined the relationship between power distance and leader
integrity, and the roles of moral disengagement and narcissism in this relationship. We analyzed paired leader–subordinate data obtained from a survey conducted with 253 leaders and their direct subordinates in China. The results show that leaders' power distance was negatively related
to their integrity, leader moral disengagement mediated the relationship between power distance and integrity, and narcissism positively moderated the relationship between power distance and moral disengagement. Moreover, narcissism strengthened the mediating effect of moral disengagement:
The higher the level of narcissism, the stronger the indirect effect of power distance on leader integrity via moral disengagement. Our findings enrich the theory of leader integrity and provide guidance for preventing damage to leader integrity.

Although recent researchers of school bullying have focused on peer bystander behavior, they have assessed the link between family-level correlates and bystander behavior to a lesser degree. We examined whether and how family functioning and moral disengagement affect four types of
bystander behavior in school bullying. Data were collected from 1,035 early adolescents at two junior high schools in China, who completed scales measuring family functioning, moral disengagement, and bystander behavior. Results show that healthier family functioning was associated with a
higher level of bystander defending behavior and a lower level of bystander assisting, reinforcing, and outsider behavior. These associations were partly mediated by adolescents' moral disengagement. Our findings have important implications for the understanding and reduction of school bullying.

During the global pandemic, lockdown policies aimed at curbing the spread of COVID-19 have been affecting all demographics. Although they may be continuing their studies online, university students may suffer severe mental consequences because of loneliness and social isolation. To
help students improve their psychological well-being, we examined the effectiveness of a web-based positive psychology intervention (PPI) with 886 students who either took part in PPI sessions or received health reminders. Results show that the PPI sessions (vs. regular health reminders) significantly
improved positive mood and mitigated negative emotions among the students. The positive effect of the intervention also remained consistent at both 3and 6-month follow-ups. These findings indicate that PPI should be embraced at universities to boost college students' psychological state.
Does Zhongyong thinking affect voice behavior? The mediating role of psychological safety

Zhongyong, as a typical Confucian thinking model, is related to employees' voice behavior. In this research we explored the relationship between Zhongyong thinking and employees' voice behavior, and examined the mediating effect of psychological safety in this relationship. Survey data
were collected from 218 part-time Master of Business Administration students from two Chinese universities. The structural equation modeling results demonstrate that Zhongyong thinking was positively related to psychological safety, and that psychological safety was positively related to voice
behavior. Further, psychological safety mediated the Zhongyong thinking–voice behavior relationship. These results suggest that organizations can encourage voice behavior by enhancing employees' Zhongyong thinking and by boosting their perception of psychological safety in the workplace.

Individuals' knowledge activity is essential for knowledge circulation in organizations. To examine the relationship between knowledge-based psychological ownership and knowledge hiding, we conducted a threewave online survey with 310 knowledge workers in China. We used the bootstrapping
method for mediation effects analysis and found that loss of knowledge power mediated the effect of knowledge-based psychological ownership on knowledge hiding. The results of a conditional process analysis further indicate that emotional intelligence attenuated the indirect impact of knowledge-based
psychological ownership on knowledge hiding through the mediator of loss of knowledge power. Our findings enhance understanding of why workers refuse to share their knowledge, and how to decrease knowledge-hiding behaviors in organizations by developing employees' emotional competency.

En primer lugar, compulsa las definiciones del concepto guerrilla con su materialización en el continente, incorporando también el concepto de terror en la discusión. Luego se enfoca en la violencia, recuperando elaboraciones teóricas y el modo en que es resignificada por los movimientos guerrilleros. Finalmente, explora los sentidos que adquiere la muerte, el martirologio y la lógica sacrificial en los diferentes espacios que la guerrilla ocupó en América Latina.
Fisonomía de la resistencia en contra de las dictaduras del Cono Sur. Balances de una revisión historiográfica
Authors: Valdés Navarro Pedro
Published: August 2021

El presente artículo tiene por objetivo revisar el panorama historiográfico en torno a las resistencias en contra de las Dictaduras militares del Cono Sur. El mapeo desarrollado persigue evidenciar los avances de las distintas historiografías locales, de tal forma de poder registrar lo que se ha escrito en torno a las diferentes formas militantes que buscaron oponerse a la anulación de la vida política, a partir de los golpes cívico militares de Paraguay, Brasil, Bolivia, Uruguay, Chile y Argentina. El comentario bibliográfico también nos permite observar los vacíos y los posibles espacios abiertos para nuevas perspectivas de estudio, no sólo en clave local, sino que también hacia una lectura continental y transnacional. Es factible evidenciar la existencia de una amplia gama de usos historiográficos en torno a la idea de resistir, lo que nos indica que estamos frente a la presencia de un concepto polisémico que abarca diferentes dimensiones históricas. Aun cuando los estudios sobre las resistencias no se han constituido como un campo articulado de estudio, sí creemos que los avances sistemáticos de las distintas historiografías locales pueden avanzar hacia la delineación de patrones comunes y visiones de conjunto.

The purpose of the article is to consider the victory of the right-wing populist party Law and Justice (PiS) (Prawo i Sprawiedliwosc) in the parliamentary elections of 2015 and 2019. There were analyzed the course, specifics and result of these elections. The possible reasons for the growth of popularity and, consequently, the electoral success of PiS and the fall in support of its main competitor Civic Platform (PO) (Platforma Obywatelska) are given. Then to study a number of possible reasons, explanations that allowed the PiS to come to authoritarian populism, and voters consciously consider the authoritarian-populist party as the ruling one. These are explanations from the point of view of internal party organization, political economy, political sociology, history (the track of dependence), the concept of authoritarian clientism, neo-authoritarianism or authoritarian populism. In the key of this concept, general considerations about the magnitude of the conceptual stretch of labeling PiS as a classic example of right-wing European populism are described, alternative views on the ideological essence of PiS are given. The conclusion also identifies and analyzes the most striking features of the political line of the PiS, the deep foundations and underlying reasons for its orientation and legitimacy, and the main psychosocial and image strategies that generally form a positive image of the PiS in the eyes of its voters.
