Topic: Learning and Teaching in mitigating the impact of television violence among adolescents

This study aims to examine and analyse the role of television programs withviolent episodes and on the Internet, on the life and behaviour of adolescents as cases serve to confirm or reject the theory that these programs incite aggressive behaviour of adolescents. We analyse how schools and teachers can help to reduce the impact of these programs on adolescent behaviour.These programs present a different way of thinking and a different way of behaviour through educational methods. Interactive learning promotes collaboration among students,meeting common goals through which they know each other better.Learning is not a product created by teachers and transmitted to students. Students create learning in their mind, or in their hands. The duty of teachers is to facilitate, guideand support students to do this transformation for them. If we want to have a fruitfulprocess of learning it is also required the active participation of the students.Students should be encouraged to stay at school, to work hard and have careerinstead of following the violent models offered by television programs. This can be accomplished through individual or group research to see violent consequences against members of society. Students should know that violence in everyday life is not like that ontelevision. Therefore, to reduce the impact of television violence we should not rely solely onfamily culture, but above all on school culture where a part of children's personality is formed

A contact problem aplication for the local behaviour of soil pile interaction

In geotechnical engineering, the main parameter for the performance of structures such as reinforced walls or deep foundations is often the shaft bearing capacity. In numerical analysis, important advancements have been made on studying the behavior of the soil and the retaining structures separately. The performance of many geotechnical foundation systems depends on the shear behavior at the soil structure interface. For deep foundations, the main component that affects friction is the horizontal earth pressure. When a pile is getting axially loaded, the soil grain network at the interface, starts to move and rearrange. In conditions of axial cyclic loading a contractive behavior of soil can generally be observed as in [1] and [2]. This can be explained by the progressive densification and relaxation of the soil under cyclic shear at the soil pile interface, as well as the local refinement of the grain distribution by grain breakage and rearrangements. As the soil contracts and decreases in volume, the normal stress around the pile surface decreases and the soil pile friction degrades. This can lead to failure of the whole geotechnical foundation system. The purpose of the work presented in this paper is to analyze locally (at the element level) the contact behavior of a soil-pile contact problem. Therefore, a 2D shear test is modeled using the Finite Element Method. The formulation of a 4 nodded zero-thickness interface element of Beer [3] is chosen with a linear interpolation function. Four constitutive contact models adapted for contact problems have been implemented. The simple Mohr-Coulomb [4] and Clough and Duncan [5] models were chosen initially, due to the ease of implementation and few number of parameters needed. After, more complicated models in the framework of elasto-plasticity such as: Lashkari [6] and Mortara [7] were implemented for the first time into the finite element code of the shear test problem. They include other phenomena such as: relative density of soil, the stress level and sand dilatancy. From the results the relation between shear displacement and shear stress has been deduced. Finally, a discussion of the advantages and the drawbacks during computation of each model is given at the end

A prospective study on geriatric abdominal surgical emergencies

Background: Geriatric population is a special subgroup of population undergoing emergency abdominal surgeries. Both higher age group and emergency surgical procedure are considered as high risk factors. In this study, we study the most common cause for geriatric population to undergo an emergency abdominal surgery and the therapeutic outcomes.Methods: All the patients aged more than 60 years coming to surgical department, BLDEU’s hospital with acute abdominal conditions. Study period was from Jan 2010 to Jan 2013. All patients aged more than 60 years old admitted with abdominal emergency conditions in department of surgery. Geriatric patients coming with blunt trauma of abdomen also included. Exclusion criteria were immunocompromised patients.Results:128 patients aged 60 years or more who presented with abdominal emergency surgical conditions were studied. Most common cause for emergency abdominal surgery was perforated peptic ulcer (38%) followed by intestinal obstruction (17%). The most common post-operative complication was surgical site infection (29%). Mortality rate was 17%. Most common cause of death was septic shock with multi organ dysfunction.Conclusion:Geriatric population is an important subgroup of population undergoing emergency abdominal surgeries. Most common cause is peptic ulcer perforation followed by intestinal obstruction due to adhesions. More than the age per say, the delay in presentation may be the cause for mortality in this age group. The therapeutic outcome in patients with co morbid factors like hypertension and diabetes mellitus in control, were similar to other patients.

Multi-lectin Affinity Chromatography and Quantitative Proteomic Analysis Reveal Differential Glycoform Levels between Prostate Cancer and Benign Prostatic Hyperplasia Sera.

Currently prostate-specific antigen is used for prostate cancer (PCa) screening, however it lacks the necessary specificity for differentiating PCa from other diseases of the prostate such as benign prostatic hyperplasia (BPH), presenting a clinical need to distinguish these cases at the molecular level. Protein glycosylation plays an important role in a number of cellular processes involved in neoplastic progression and is aberrant in PCa. In this study, we systematically interrogate the alterations in the circulating levels of hundreds of serum proteins and their glycoforms in PCa and BPH samples using multi-lectin affinity chromatography and quantitative mass spectrometry-based proteomics. Specific lectins (AAL, PHA-L and PHA-E) were used to target and chromatographically separate core-fucosylated and highly-branched protein glycoforms for analysis, as differential expression of these glycan types have been previously associated with PCa. Global levels of CD5L, CFP, C8A, BST1, and C7 were significantly increased in the PCa samples. Notable glycoform-specific alterations between BPH and PCa were identified among proteins CD163, C4A, and ATRN in the PHA-L/E fraction and among C4BPB and AZGP1 glycoforms in the AAL fraction. Despite these modest differences, substantial similarities in glycoproteomic profiles were observed between PCa and BPH sera

Empyema Thoracis- the role of open thoracotomy with decortication in the era of video-assisted thoracoscopic surgery

Background: Empyema Thoracis, a condition in which purulent fluid accumulates within the pleural cavity, is commonly caused by bacterial infection (both Gram- positive and Gram-negative), such as Mycobacterium tuberculosis, and rarely by fungal infection. Timely intervention significantly reduces morbidity and mortality. Surgical intervention is needed in advanced disease. This study aimed evaluate decortications performed through video-assisted thoracoscopic surgery (VATS) and open thoracotomy. Methods: This retrospective study included 47 patients who underwent decortications by either VATS or open thoracotomy for empyema Thoracis at the Department of Surgery of, BLDE DU Shri B M Patil Medical College from May 2015 to August 2020. Results: Tuberculosis was the most common etiological factor for empyema Thoracis. In 19 patients who underwent VATS decortications, VATS was converted to open thoracotomy in 11 patients. Only 8 patients achieved successful decortication with VATS. Thirty- nine patients (including 11 whose VATS was converted to open thoracotomy) underwent successful open thoracotomy decortications. Thirty-two patients had postoperative bronchopleural fistula, and all cases were successfully managed conservatively. The timing of the surgical intervention is critical in reducing morbidity and mortality. The more advanced the disease, the higher the failure rate of VATS in attaining complete decortications. Conclusion: Open thoracotomy decortication remains the gold standard in attaining complete decortications in advanced empyema Thoracis

An aplication of MCDA method to evaluate and select the most suitable landfill sites for urban waste. A project case study for Berat County. Albania

Waste management system needs clear and strict management policy. They also need a process of evaluating and selecting the most appropriate landfill sites that respect the restrictions and constraints dictated by the presence of the population in that area, with respect to ecological ecosystems and other factors. In addition to the geographical and geological criteria and other specifications that are defined by traditional selection procedures, there are new factors adding to the old constraints and limitations. Urban waste is produced in large quantities in our cities, every year. As a result, the number of sites should increase with the population growth as well as the increase in urban waste products. On the other hand, the eligibility criteria and adding constraints and limitations make it more difficult to choose suitable sites. Environmental and local and state regulations limit the number of choices as well as areas and volume of sites making their selection more difficult, posing a real challenge for specialists. Specialists need to use the Geospatial Information System (GIS) as well as the method of Multiple Critical Decision Analysis (MCDA) to select the most optimal location. Our study aims to apply MCDA integrated with GIS to select potential sites for urban waste deposition. The method of hierarchy analysis (AHP) will be used to weight and rank the constraints and criteria. This article is part of a potential project we are working to propose to Berat County, Albania
