Pedagogical appreciation of juvenile aggressiveness: socio-perceptive aspects and readiness of interference
Authors: Rean Artur , Konovalov Ivan
Published: October 2021

Introduction. The topicality of the research is caused by both traditions of the scientific research of pedagogical social perception and extremely high degree of attention on the side of political, professional and expert community to the problem of education. The pedagogical study of aggression plays an important role in understanding of the strategy for developing programs of improving professional competence of pedagogues and specialists in the sphere of prevention of juvenile delinquent behavior.

Aim. Some research problems were examined in order to find the answers to the following problems: the facts that prove aggressive juvenile delinquent behavior, the reasons of juvenile behavior, the reaction of pedagogues on conflict situations and their emotions when they confront situations of aggressive behavior.

Methodology and methods. In the process of research different methods were used such as psychological tests, different types of questionnaires and others. More than 13000 of pedagogues from six federal districts participated in the project “Pedagogue as a subject of upbringing of the youth and prevention of delinquent behavior”.

The results. Data are given about the fact that pedagogues consider depressed state and aggressive behavior of the child to be the testimony of aggressive behavior of adults towards the child. Boys are more inclined to be aggressive, while the girls try not to show obviously their aggressive behavior. Children from troubled and incomplete families are more aggressive. Attention is drawn to the fact that the main risks of aggressive behavior of juveniles are in the families where the parents are indifferent to the child, do not pay attention to him or her or their requirements are contradictory. The research showed that pedagogues feel trouble, anxiety and fear when they come across conflict situations between the pupils.

Practical significance. The results of the research are very important both in the context of improving the programs for pedagogues and psychologists in the sphere of juvenile deviant and antisocial behavior prevention and in the context of educational and youth policy and its tasks.

A RANDOMISED, PROSPECTIVE, PARALLELAND OPEN LABEL STUDY TO COMPARE EFFICACY AND SAFETY OF METFORMIN PLUS ROSUVASTATIN AND GLIMEPIRIDE PLUS ROSUVASTATIN IN PATIENTS OF COEXISTING NON-ALCOHOLIC FATTY LIVER DISEASE (NAFLD) AND TYPE 2 DIABETES MELLITUS (T2DM)
Authors: kaur Prabhsimran , Randhawa Gurpreet Kaur , Kumar Salwan Surinder
Published: October 2021

Background and Objectives: NAFLD and T2DM has global prevalence of 55.5% with currently no approved treatment. There is insufcient data
for its pharmacotherapy. The sharing of risk factors, most common being the insulin resistance between NAFLD and T2DM, makes the antidiabetic
drugs, with effect on insulin resistance, the potential treatment options. The aim was to compare efcacy and safety of antidiabetic drugs i.e.
Metformin and Glimepiride with concomitant Rosuvastatin in NAFLD coexistent with T2DM.
Methods: Randomized, prospective, parallel and open-label study recruited 60 patients of concomitant NAFLD and T2DM after getting
Institutional Review Board approval. Patients of either sex (20-60 years) with NAFLD (ultrasound diagnosed & raised AST 50-150 U/L) and
T2DM(FBS> 126mg/dl) were recruited in medicine OPD after obtaining written informed consent. Chronic alcohol users and pregnancy cases
were excluded. Patients were randomised into Group A[Rosuvastatin(10mg OD)+ Metformin(1gm BD)] & Group B[Rosuvastatin(10mg
OD)+Glimepiride(3mg BD)]. Primary outcome was improvement in hepatic parameters and ultrasound grading of liver. Secondary outcomes
were improvement in anthropometric, glycaemic and lipid parameters and assessment of safety.
Results: Group A caused signicant(p<0.05) reduction in hepatic parameters(S.Bilirubin & AST). Group A and B showed non-signicant
improvement(p>0.05) in ultrasound grading of liver, respectively (24% vs 20% patients). Intergroup difference was signicant(p<0.05) for weight
and BMI in Group A. Both groups showed highly signicant(p<0.001) reduction in glycaemic parameters and signicant(p<0.05) reduction in
lipid parameters. Both treatments were safe.
Conclusion: Metformin plus Rosuvastatin seems to be more efcacious in NAFLD and T2DM over 90 days. These drugs could improve prognosis
because of insulin sensitising action and additional benets in cancers, cardiovascular diseases. Further studies are required to strengthen these
ndings which may help in nding a standard treatment for NAFLD and T2DM.
STUDY OF DIC AS AN OBSTETRIC COMPLICATION AND FETO-MATERNAL OUTCOME
Authors: Nenuji Hemali , shah Tushar
Published: October 2021

Disseminated intravascular coagulation (DIC) occurs when the nely
controlled process of haemostasis becomes disrupted. As a result,
coagulant responses can change from being naturally protective to the
host into a maladaptive response with pathological consequences.
Clinically, this is reected in the increased morbidity and mortality that
is associated with DIC. The recognition that DIC arises as a
complication of different disease states reects the variety of ways in
which clinical events can uncouple normal haemostasis.

Innovative Energy Arbitrage Models and Algorithms for Battery Energy Storage Systems in Electricity Market
Authors: Li Ang , Peng Jiming , Fan Lei , Du Pengwei
Published: October 2021

Maintaining the balance between electricity production and consumption is an essential task in the operations of modern power grids. In recent years, battery energy storage system (BESS) has been gaining more and more attention owning to its decreasing capital cost, high flexibility and short response time. However, there exist several technical challenges in developing accurate models and effective algorithms for the operations of BESS. One major challenge is that in order to precisely describe the changing dynamics of battery status, usually highly non-linear functions and integer variables must be used in the model, leading to optimization models with nonlinear and non-convex objective function/constraints that are difficult to handle. To address the above challenges, in this paper we first explore the physical law in the battery charging and discharging process to develop a new model which naturally addresses both the charging and discharging processes through a single current decision variable. Then we propose to approximate the dependency relationship between the open circuit voltage (OCV) and the state of charge (SOC) by some linear functions. This leads to a new non-convex quadratic programming model with linear and bilinear constraints (BLCQP) for the identification of the optimal operational strategy for the BESS. To cope with the bilinear constraints in the BLCQP, we introduce a novel transformation technique to transfer the original BLCQP into another equivalent exponential optimization problem with linear constraints (LCEO). A new sequential linear and quadratic programming approach (SLQP) for the LCEO is developed and its convergence is established. Preliminary experiments are conducted to demonstrate the efficacy of the new model and the efficiency of the new algorithm.

In the learning process not every student succeeds through the learning process done in other words not every student can achieve the learning objectives as expected. This is due to abstract mathematical concepts. Many factors influence it, including intelligence, learning readiness, interests, motivation, teacher abilities, maturity, family, school and community. The purpose of this study is to know the meaningful influence of learning on students' math learning outcomes. This research uses descriptive quantitative methods. The population in this study is all grade VII students of SMPN 1 Katibung Lampung Selatan. The results of the hypothesis test using the t-test showed the influence of meaningful learning application on improving the results of mathematics learning students of grade VII SMPN 1 Katibung south lampung. Students who apply meaningful learning have a higher average math learning outcome than the average student learning outcomes that do not apply meaningful learning. Thus, the application of meaningful learning can improve students' math learning outcomes.
Strategies for post-conflict development of the Health Systems in Somalia: lessons from selected countries
Authors: Omar Maye
Published: October 2021

Until the beginning of 1991, Somalia had a reasonable health care system with a good number of tertiary hospitals in Mogadishu and Hargeisa, some regional hospitals, district hospitals, clinics, child and mother health centres (CMH) and out-patient dispensaries. However, the conflict resulting from the civil war has destroyed the public health care system which existed in the country.
Somalia was not alone in having conflicts. The total number of conflicts in the world in 2017 was 49, many of them have now entered post-conflict phases, where open warfare has come to an end.  There is growing evidence that conflict has a devastating impact on health systems and the health status of the population.
In Somalia, the post-conflict phase provides a unique window of opportunity for health sector development and reform. At this juncture, health systems in Somalia face the double burden of a flawed pre-conflict health system, characterised by deficiencies and inequities, and the long-term impact of conflict on the health status of the population and its resultant strain on the health system.
This review article analyses the framework for the rehabilitation of health systems in post-conflict countries. Such knowledge can be  applied in the rehabilitation and development of health systems in Somalia along the lines of the World Health Organization’s health system building blocks.
The impact of conflict on the health status of the population as well as the health system can be catastrophic and be felt for years after the State has entered the post-conflict phase, but also provides an opportunity for reforms of the affected State’s health sector.

Current perspective and future research directions on defecation clarification for the manufacture of raw sugar
Authors: Bakir Cumhur Hakan , Rackemann Darryn W. , Doherty William O.S.
Published: October 2021

Juice clarification is integral to the sugar-manufacturing process and determines the quality of clarified juice which is subsequently processed to produce sugar. Clarification performance is defined largely by turbidity of the clarified juice, but the presence of soluble impurities, colour and colour precursors, polysaccharides and proteins influence heat-transfer performance of evaporators and evaporating crystallizers, the crystallisation performance in evaporating crystallizers and the achievable yield and quality of sugar. The conventional defecation process is inadequate to remove these nonsucrose impurities, and the gradual worldwide transition to green-cane harvesting is introducing greater levels of impurities into the cane supply. As a result, the clarification station is now having to deal with not only the endogenous impurities (e.g. stalk impurities) but also the trash (leaves and tops) impurities. This paper reviews work that has been conducted over the years to remove these impurities and presents future research directions that should improve clarification performance. Examples of future research directions include development of multi-functional nanoparticles to significantly improve impurity removal; processing strategies to enhance precipitation of proteins and polysaccharides; and ballasting and adsorbent agents.

Authors: Vartolomei Ana Maria , Calinescu Ioan , Dan Diana Madalina , Gavrila Adina Ionuta
Published: October 2021

Chemical methods for the synthesis of esters require the use of high temperatures in the presence of chemical catalysts resulting in undesirable by-products. To avoid these problems the use of biocatalysis can lead to greener products. The aim of this papar is to study the synergism of enzyme catalysis with unconventional techniques suc as microwave or ultrasound assited processes. The effect of different reaction parameters, such as temperature, enzyme loading, ultrasonic amplitude and duty cycle, on the enzymatic synthesis of isoamyl acetate has been evaluated. To highlight the efficiency of unconventional techniques, experiments using conventional methods were also performed. The concetrations of isoamyl acetate obtained by unconventional methods were higher than those achieved under conventional heating, as 478 mgester/gmixture was obtained with ultrasounds in 1 h using 25g/L of enzyme loading, at 50ºC as compared to 387 mgester/gmixture by conventional methods. Mild process conditions and using green techniques (microwaves and ultrasounds) make the biocatalytic procedure a useful way to synthetise esters with application on food, pharmaceutical and cosmetic industries.
Biomedical Named Entity Recognition Using the SVM Methodologies and bio Tagging Schemes
Authors: Meenachisundaram Thiyagu , Dhanabalachandran Manjula
Published: October 2021

Biomedical Named Entity Recognition (BNER) is identification of entities such as drugs, genes, and chemicals from biomedical text, which help in information extraction from the domain literature. It would allow extracting information such as drug profiles, similar or related drugs and associations between drugs and their targets. This venue presents opportunities for improvement even though many machine learning methods have been applied. The efficiency can be improved in case of biological related chemical entities as there are varied structure and properties. This new approach combines two state-of-the-art algorithms and aims to improve the performance by applying it to varied sets of features including linguistic, orthographic, Morphological, domain features and local context features. It uses the sequence tagging capability of CRF to identify the boundary of the entity and classification efficiency of SVM to detect subtypes in BNER. The method is tested on two different datasets 1) GENIA and 2) CHEMDNER corpus with different types of entities. The result shows that proposed hybrid method enhances the BNER compared to the conventional machine learning algorithms. Moreover the detailed study of SVM and the methodologies has been discussed clearly. The linear and non linear text classification can be mapped clearly in the section 3. The final section describes the results and the evaluation of the proposed method.

Published: October 2021

Lead ions removal from aqueous solutions onto bean shells is presented in this paper. The experiments were conducted in a batch system. The bean shells samples were rinsed with distilled water before the adsorption experiments. The analysis of the rinsed water showed that a significant amount of alkali and alkaline-earth metal ions are transferred from the adsorbent structure into the rinsed solution during the rinsing process. The COD analysis showed that these waters should be treated before being discharged into the surrounding watercourses. The influence of different process parameters (the pH value of the solution, the initial metal ions concentration, and the initial mass of the adsorbent) on the adsorption capacity was investigated. The adsorption capacity was higher at higher pH values of the solution. The adsorption capacity showed a decrease with the increase in the mass of the adsorbent. The increase in the initial metal ions concentration was shown to lead to an increase in the adsorption capacity until 0.8 g dm-3, after which a slight decrease was noted. Characterization of the adsorbent was performed by SEM-EDX, DTA-TGA, and FTIR analysis. The SEM-EDX analysis indicates a change in the morphology of the sample after the adsorption, as well as that K and Mg are possibly exchanged with lead ions during the adsorption process. The results obtained by the DTA-TGA analysis showed a weight loss of 77.8 % in the temperature range from 20oC to 900oC. The FTIR analysis indicated that the amide group is involved in the adsorption process. The pseudo-second order kinetic model was shown to be the best fit for the analyzed data, which led to the conclusion that chemisorption was a possible way of binding lead ions onto the surface of the bean shells. The Hill isotherm model was the best model for the analyzed adsorption equilibrium data. Obtained thermodynamic data indicated that the adsorption process was spontaneous, endothermic, and disordered, in which lead ions are bound to the surface of the bean shells by chemisorption. The maximum achieved adsorption capacity was 46.36 mg g-1.

Published: October 2021

A successfully implemented screening program for cervical cancer is essential for detecting
cervical intraepithelial lesions which offer the possibility of appropriate management and monitoring,
implicitly the limitation of the progression to an invasive form of cancer. For different grades of squamous intraepithelial lesions, the use of vaginal tablets or applicators based on various natural substances as hyaluronic acid, beta-glucan and Coriolus Versicolor is possible with the purpose of expectative management or prior and post excisional intervention. We present the incidence trend of abnormal Pap smear results for the last five years in the University Emergency Hospital of Bucharest, with a summary of the literature regarding the biochemical mechanism of the main natural components from vaginal tablets used in the management of precancerous cervical lesions HPV induced and we share our personal experience with three clinical cases that benefited from this therapy. As there is a therapeutic window between the Pap-smear result, colposcopy and preparing for intervention, local treatment with natural components is a suitable choice as it is easy to use, inexpensive and efficient. The conclusion we reached is that the vaginal treatment with natural substances can be useful in terms of improving the local inflammatory process on the one hand and lubricating and regenerating tissues with the improvement of subsequent procedural performance on the other.

Published: October 2021

In the article, based on the analysis of the works of D. N. Pryanishnikov, it is shown that these works do not contain the completeness of scientific justifications for the industrial production of mineral fertilizers.

It is revealed that the industry of mineral fertilizers production created in the USSR, as devoid of sufficient scientific justification, led to unproductive costs in agriculture, unbearable for the USSR.

It is shown that problems in food production are the result of institutional traps, the opening and getting rid of which is impossible without the Provision for scientific discussions.

It is obvious that without overcoming the institutional pitfalls, food production will only decline, bringing the threat of famine closer to the Third World war for fertile land.

Aims: The aim of this study is to determine, compare the Cg-A levels in saliva and plasma in periodontal healthy, in patients with periodontal disease and correlate the same with the stress factor.Materials and Methods: The study involved thirty subjects. There were categorized into three groups with Group I (10 subjects with healthy periodontal status), Group II (10 subjects with mild to moderate periodontitis) and Group III (10 subjects with severe periodontitis). The clinical parameters such as plaque index, gingival bleeding index, clinical attachment loss and probing depth were recorded. Stress was measured using Holme and Rahe stress rating scale. Blood and Saliva sample were collected and Serum Plasma and Saliva CgA levels evaluated using ELISA. The data obtained from all the three groups were analyzed using SPSS Systat 12 software. The mean variables between the three groups were analysed using Kruskal Wallis test. The correlation between the variables and the stress scores was assessed by Pearson’s correlation test.Results: The results of the study showed significantly higher CgA levels in saliva and plasma of patients with severe periodontitis compared with moderate periodontitis and healthy individuals (P < 0.05). There was also a positive correlation between stress scores and Salivary, Serum CgA levels and all clinical parameters.Conclusion: A significant association between elevated Cg A levels in saliva and plasma with periodontal disease was present in our study. The results suggest that Salivary and Plasma Cg A can be considered as a useful biomarker for evaluating etiopathogenesis of Periodontitis

Background: The aim of this study was to compare between computer guided and free hand immediate implant placement in fresh extraction sockets in terms of accuracy of implant positioning.Methods: This is a randomized controlled clinical study, which used CBCT imaging and flapless surgical technique to place implants in fresh extraction sockets. Accuracy measurements were done using BluSky®1software. A total of 22 patients were recruited according to inclusion and exclusion criteria. Results: The mean values at the implant shoulder for implants inserted using computer surgical guides and those inserted using free hand technique in the mesiodistal direction were 0.69 and 1.43mm, respectively. While in the buccolingual direction they were 0.96 and 1.34mm, respectively. At the implant apex in the mesiodistal direction, they were 1.26 and 2.35mm, respectively. While in the buccolingual direction, they were 1.64 and 1.70mm, respectively. For the angular deviation they were 1.57 and 3.18mm respectively in the mesiodistal direction. Whilein the buccolingual direction were 1.29 and 7.76mm, respectively.Conclusions: Accuracy of computer guided immediate implant insertion surpasses the freehand technique in the buccolingual direction in terms of placing Immediate Implants in fresh extraction sockets in maxillary estheticregion and thus the prosthetic aspect.
Systematic Review of Neonatal Pain Management with 25% Dextrose Versus Direct Breast Feed Milk During Painful Procedure
Authors: Malarselvi A  , Anu Gauba  , Poonam Joshi
Published: October 2021

This systematic review is the product of 25 top published journals. The search engines adopted in this study werePubMed, Medline, CINHAL, Cochrane Library, Google Scholar, and Research gate. The inclusion criteria were:1.Papers published between 2000-2020, 2.Top tier journal articles (High quality), 3. Term Healthy neonates and preterm neonates, 4.Neonates undergoing various painful procedures and Neonates receive different pain relief interventions. The key searching words were Neonates, Painful Procedures, BCG Vaccination, 25% Dextrose. The present paper highlights that 25% dextrose and direct breastfeed milk relieves neonatal pain. The gate-control theory also discusses the idea of central control through modulation of nerve impulses in descending fibbers from the brain. The gate tends to close when cognitive activities such as distraction (e.g., breastfeeding) are processed along these fibres, therefore preventing the transmission of pain through a “descending blocking action.” This mechanism also affects various pain entities such as anxiety, anticipation, and memory of prior experiences.This paper shows the research gaps from different studies in the review of the literature. In this present study of systematic review, 25 recent multiple interventions based on RCTs studies between 2010 to 2020 were systematically reviewed using the keywords search method. The findings are discussed and research gaps related to the RCTs are listed accordingly.

Dental development is an interactive event between the oral epithelium and mesenchymal tissue. Any abnormal interaction at any step may result in ectopic teeth development.Teeth that are ectopically developed in non- dental areas has been reported in the nasal cavity, nasal septum, chin and maxillary sinus. Ectopic teeth in the maxillary sinus are asymptomatic in most cases;however it may precipitate sinusitis or sometimes result in ophthalmic symptoms.We report a case of ectopic maxillary third molar inthe right maxillary sinus with a non-specific symptoms which was enucleated out with the surrounding dentigerous cyst via a Caldwell-Luc procedure.
