Development of Water-Based Drilling Fluid in Mitigation of Differential Sticking Tendency
Authors: Yalman Emine , Federer-Kovacs Gabriella , Depci Tolga
Published: March 2022

The objective of the study is to design a drilling fluid that prevents differential pressure pipe sticking tendency caused by drilling fluid with fly ash that is an industrial waste generated from the combustion of coal. To this end, drilling fluid samples were prepared with different particle sizes obtained through the sieving and grinding process and increasing concentrations of fly ash. Differential pipe sticking tests of the samples were performed by applying 3.447 MPa (500 psi) pressure and using a Fann Model 21150 Differential Sticking Tester in order to determine how the coefficient of sticking and torque reading varied with the fly ash. From the results, it was observed that the coefficient of sticking and torque reading of the water-based drilling fluids decreased up to a specific concentration as the concentration of fly ash increased. Furthermore, particle size analysis illustrated that the coefficient of sticking and torque of the drilling fluid differs depending on the particle size of fly ash introduced. The drilling fluid designed with ground fly ash demonstrated lower sticking coefficient and torque reading than that of drilling fluids formulated with raw and sieved fly ashes. The experimental study revealed that fly ash is a promising additive in the mitigation of differential sticking tendency caused by water-based drilling fluids.
DEVELOPMENT OF A 3D NUMERICAL MODEL FOR SIMULATING A BLAST WAVE PROPAGATION SYSTEM CONSIDERING THE POSITION OF THE BLASTING HOLE AND IN-SITU DISCONTINUITIES

Published: March 2022

Blasting operations are one of the most important parts of geotechnical and mining projects. Most rocks naturally have a series of discontinuities that significantly affect their responses to blast waves. In this paper, the propagation of a blast wave in one intact rock and four rocks with different joint conditions are simulated by a 3-dimensional distinct element code. The results showed that the joint in the model acted as a wave barrier and passed part of the waves, absorbed a portion, and reflected the remaining part into the model. In other words, a discontinuity reduces the energy of the wave and causes more wave attenuation. In addition, a shorter distance between the joint and the hole causes slower wave propagation and greater damping. Moreover, the results showed that the smaller the angle between the discontinuity and axis of the blast holes, the more stress occurs in the rock bench.

Authors: Bohanek Vječislav , Dobrilović Mario , Štimac Barbara , Stanković Siniša
Published: March 2022

Shaped charges are widely used in many different fields. The two main users of shaped charges are the military, where shaped charges are used as a weapon against armoured targets, and the oil industry, to perforate wells. Very often, shaped charges are the subject of scientific research focused on optimising shaped charge parameters and increasing the efficiency of shaped charges. Considering a significant number of parameters affecting the penetration depth, the optimization of shaped charge parameters is a complex process. This paper describes research on the efficiency of small handmade shaped charges. In this research, two methods are used, the first one involves simulations with numerical software and the second one is site testing. AUTODYN software was used for the numerical simulations. One of the simulations was focused on the shape and velocity of the shaped charge jet and the second on the penetration of the jet into the target material. On-site efficiency of shaped charges at different standoff distances was tested. The experimental result was compared with the AUTODYN simulation result for hand-made shaped charges placed at a distance of 90 mm from the target material. The results of the simulations agree very well with the results of the site tests. Some advantages and disadvantages of each approach are also observed.
DETERMINATION OF DETONATION FRONT CURVATURE RADIUS OF ANFO EXPLOSIVES AND ITS IMPORTANCE IN NUMERICAL MODELLING OF DETONATION WITH THE WOOD-KIRKWOOD MODEL
Authors: Štimac Tumara Barbara , Dobrilović Mario , Škrlec Vinko , Sućeska Muhamed
Published: March 2022

Nitratebased commercial explosives, such as ANFO (ammonium nitrate/fuel oil mixture) and emulsion explosives, are characterized by a curved detonation front. The curvature is directly related to the rate of radial expansion of detonation products in the detonation driving zone and the rate of chemical reactions, and it is one of the characteristics of nonideal explosives. The detonation theories used to model the nonideal behaviour of explosives require both reaction rate and rate of radial expansion to be known/specified as input data. Unfortunately, neither can be measured and what is mostly used is a link between these rates and parameters which can be more easily measured. In this paper, the Wood-Kirkwood approach of determination of radial expansion through the radius of detonation front curvature and the electro-optical technique for experimental determination of detonation front curvature of ANFO explosives is applied. It was shown that an experimentally determined radius of detonation front curvature vs charge diameter, incorporated in the Wood-Kirkwood detonation theory, can satisfactorily reproduce experimental detonation velocity-charge diameter data for ANFO explosives, especially when the pressure-based reaction rate law is also calibrated (D=1.3 and k=0.06 1/(μs/GPaD)).

BACKGROUND: Inflammatory periodontal diseases are an important medical and social problem, since more than 90% of the adult population of the Russian Federation suffer from this pathology.
AIM: The work is to study the effectiveness of the treatment of chronic catarrhal gingivitis in employees of a limestone mining enterprise based on clinical and microbiological methods.
MATERIALS AND METHODS: We examined 214 employees aged 2227 years (machinists, crushers, sorters and workers of the administrative and economic part) working at a limestone mining enterprise (Ufa). Chronic catarrhal gingivitis was detected in 61 patients. To determine the effectiveness of treatment by randomization, patients were divided into the 1st (main) group (n=31) with chronic catarrhal gingivitis, who were prescribed the treatment recommended by us, and the 2nd (comparison) group (n=30) with chronic catarrhal gingivitis, who were treated with basic therapy.
Clinical studies were conducted according to the standard scheme and recorded in the medical history. anamnesis was collected, dental formula, plaque, swelling and hyperemia of the gums were registered during the dental examination, bite and occlusive contacts were evaluated.
The following indices were used: hygienic, bleeding, papillary-marginal-alveolar (PMA).
RESULTS: Clinical and functional data of these patients were obtained. A microbiological assessment of the gingival fluid content is given. Issues of the diagnostics and treatment of patients with chronic gingivitis (catarrhal) with the use of a drug based on lactobacilli and bifidobacteria and Placentol are considered. The effectiveness of the treatment has been determined.
CONCLUSION: The proposed method using resorption of Smart candies and rinsing with Placentol balm in patients with chronic catarrhal gingivitis working at a limestone mining enterprise is more effective and can be included in the protocol for the treatment of patients with chronic catarrhal gingivitis working at limestone mining.

Published: March 2022

This article provides a systematic review of studies on a new biological treatment method called regenerative endodontic technique. Databases of Scopus, Web of Science, and MedLine were searched for relevant studies. Dental trauma most common occurs in children and the most common cause of the loss of viability of the pulp of permanent teeth with incomplete root development. Treatment of these teeth takes time and technically complex. Thus, a technique was proposed that could use the potential of apical papilla stem cells, leading to the refilling of the root canal with vital tissue through the regenerative endodontic technique. It is necessary to pay due attention to the use of regenerative endodontic techniques, especially in cases where the root development is incomplete. The use of mineral trioxide aggregate is unlikely to improve the condition of the tooth.

Cultivar and Harvest Stage Effects on Nutritive Value of Whole Crop Oat (Avena sativa L.) Silages
Authors: KILIÇALP Numan
Published: March 2022

This study was carried out to investigate the effects of feed value and dry matter (DM) on rumen degradability properties of silages of oat (Avena sativa L.) cultivars (Kahraman and Kırklar) at different harvest stages (pre-flowering, flowering, milk, soft dough). Field and digestibility trials were carried out in randomized blocks, in a 2x4 factorial trial design during the 2016-2017 vegetation period. For the rumen digestibility of silages, three heads of Karayaka rams with rumen cannulated, average 50±3 kg body weight and 3 years old were used. As a result of the experiment, It was observed that the crude protein (CP) level of Kahraman cultivar was higher than that of Kırklar cultivar, and the CP content of cultivars decreased from the pre-flowering period to the soft dough period. In addition, with the progress of the growing period, the neutral detergent fiber (NDF) content of the varieties increased. Also, the net energy lactation (NEL) level of Kırklar cultivar was higher than Kahraman cultivar. However, the NEL levels of the cultivars decreased with the progression of the growing period. The water solubility of DM and CP of Kahraman cultivar was higher than that of Kırklar cultivar. In addition, effective dry matter degradability (EDMD) decreased with growth period in both cultivars. It was observed that the effective crude protein degradability (ECPD) rate of Kahraman cultivar was higher than that of Kırklar cultivar and ECPD rate of cultivars decreased with the progress of the growing period. As a result, Kahraman cultivar may be preferred more than Kırklar cultivar, since it has higher EDMD and ECPD in the rumen and also has higher RFV value.

Authors: Koneva Elena V.
Published: March 2022

The article is devoted to the methodological issues of the analysis of information materials within the framework of psychological forensic expertise and psychological humanitarian expertise. Authorship and publication of information materials can be viewed as a kind of communication between their creator and consumers. In both types of expertise, currently the material is analyzed mainly from the standpoint of one of the parties to communication, which is partly due to objective circumstances. However, this makes it difficult to develop criteria for expert analysis necessary for reasoned answers to the questions posed to the expert examination. Problem has been resolved in relation to the psychological forensic expertise, but remains acute in relation to the humanitarian expertise. Analysis of the characteristics of perception and understanding of the information product by the consumer can help to resolve the indicated problem.

The article is devoted to the research of current state of information intermediaries’ legal control from the point of view its adequacy, certainty and meeting the needs of modern legal practice and B2B-segment of Russia. The author pays special attention to the issue of improving the status of information intermediaries in terms of balancing the rights and obligations of such entities, determining reasonable and protecting public and private interests conditions of responsibility of online platforms and web services as information intermediaries. On the example of cases from practice in the field of Internet marketing and data protection, the author explains the current legal gaps. They prevent the full restoration and protection of the rights and legitimate interests of citizens interacting with digital platforms that position themselves as information intermediaries. The paper, basing on the materials of modern judicial practice, defines the conditions for the responsibility of partner networks for the actions of entities affiliated with them that break national legislation. In order to better ensure the rights of personal data subjects, the author substantiates the need to distinguish between the categories of «operator» and «processor» of personal data in the legislation, as well as expanding the conditions for processing personal data defined in the law on the basis of agency contracts.
Automatic Generation and Optimization of Combinatorial Test Cases from UML Activity Diagram Using Particle Swarm Optimization
Authors: Tatale Subhash , Prakash Vudatha Chandra
Published: March 2022

Generation of test cases is one of the essential activities of the software testing process. The process of executing a programme to identify defects to improve the system's quality is known as software testing. Manually writing test cases takes time, effort, and money. On the other hand, generating test cases automatically is the solution to this problem. For this automation process, a model-based test case generation technique would be acceptable. A model is usually required to generate test cases in the model-based testing technique. Nowadays, researchers have relied on the activity diagram to generate test cases. Test cases for combinatorial logic systems are required. Combinatorial testing is essential for producing a small number of test cases and identifying errors occurred by interactions between system input parameters. Information about constraints, parameters and its values are required for generation of test cases. It is difficult to extract information regarding constraints, parameters, its values, and interactions between parameters from an Activity Diagram. A novel approach is proposed to extract this information from an Activity Diagram. The authors created a tool that automatically generates combinatorial test cases using UML Activity Diagrams. The proposed tool has two main parts. First, the combinatorial test design model is developed for extraction of input parameters. Second part is generation of optimized number of combinatorial test cases using Particle Swarm Optimization algorithm. Finally, the authors experimented on a real-world case study namely viz. Railway Reservation using the proposed tool, and it is shown that the proposed tool generated optimum number of combinatorial test cases.

The way we use video streaming is evolving. Users used to broadcast their videos on social media platforms. These platforms enable them to interact from anywhere they want. Recently, there has been a wide range of people who use live video streaming platforms regularly. Thanks to high-speed Internet connections, live video streaming is now easier than ever. Many of these platforms broadcast live video feeds of electronic games, so young streamers use them to make money. Live streaming refers to media that is simultaneously broadcasted and recorded online in real-time. Despite the growing popularity of these platforms, there is a risk that this technology will be abused. Several other recorded cases of abuse have resulted in the emerging popularity of live streaming platforms. Many criminal and public proceedings may rely on information linked to a normal Web user's Online activity. Examining the web browser's history or cache may reveal helpful information about the suspect's activities. The evidence can reveal keys that might lead to this individual being convicted or clear. This work continues what was previously done to reconstruct cached video streams from YouTube and Twitter on Firefox. Our main aim in this paper is to examine data from a cached live stream using YouTube Gaming/Live and Nimo TV on Firefox and Chromium browsers.
Fine-Tuning BERT Based Approach for Multi-Class Sentiment Analysis on Twitter Emotion Data
Authors: Kannan Eswariah , Kothamasu Lakshmi Anusha
Published: March 2022

Tweets are difficult to classify due to their simplicity and frequent use of non-standard orthodoxy or slang words. Although several studies have identified highly accurate sentiment data classifications, most have not been tested on Twitter data. Previous research on sentiment interpretation focused on binary or ternary sentiments in monolingual texts. However, emotions emerge in bilingual and multilingual texts. The emotions expressed in today's social media, including microblogs, are different. We use a dataset that combines everyday dialogue, easy and emotional stimulation to carry out the algorithm to create a balanced dataset with five labels: joy, sad, anger, fear, and neutral. This entails the preparation of datasets and conventional machine learning models. We categorized tweets using the Bidirectional Encoder Representations from Transformers (BERT) language model but are pre-trained in plain text instead of tweets using BERT Transfer Learning (TensorFlow Keras). In this paper we use the HuggingFace’s transformers library to fine-tune pretrained BERT model for a classification task which is termed as modified (M-BERT). Our modified (M-BERT) model is an average F1-score of 97.63% in all of our taxonomy, which leaves more space for change, is our modified (M-BERT) model. We show that the dual use of an F1-score as a combination of M-BERT and Machine Learning methods increases classification accuracy by 24.92%. as related to baseline BERT model.

Published: March 2022

In this paper, the proposed algorithm to detect the bias from the datasets and to mitigate the bias in the datasets was observed. The consequences of this work shows that not only bias in a model can be decreased without forfeiting model performance rate, but improving the performance. Class imbalance, KL divergence, sample disparity and Kolmogorov-Smirnov (KS) are the pre-training metrics used in the work. Each metric is given weightage and the features are detected based on the maximum weightage. The model is trained to learn the unbiased data and shows the significant improvement in the performance of the system. ROC curve, False Positive Rate and False Negative Rate is used for bias trade-off. The comparison between FPR and FNR before mitigating bias and after mitigating bias is performed and its results are significantly improved.
Enhanced CNN Model for Pancreatic Ductal Adenocarcinoma Classification Based on Proteomic Data
Authors: Laxminarayanamma Kadiyala , Krishnaiah Ravilla Venkata , Sammulal Porika
Published: March 2022

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest tumors, with just around nine percent of those diagnosed surviving for more than five years after diagnosis. A significant part of the poor result may be attributed to late detection. However, the illness is identified at an initial phase. While growths remain quite tiny and manageable, five-year existence rates can rise to as high as seventy percent. Because of this, there is a huge clinical demand for the creation of a non-invasive examination targeted at the earliest identification of PDAC, which has the ability to recover the current prospects of patients. Considering the grim future for pancreatic cancer, new strategies for early detection and prevention must be developed as rapidly as feasible. Researchers have revealed that proteomics technology is effective in discovering important biomarkers for early-stage pancreatic cancer, according to recent research. One of the most challenging difficulties is recognizing and collecting physiologically relevant information from the huge quantity of data collected when it comes to proteome profiling. Because of the tremendous complexity of proteomics datasets and the fact that they typically have minuscule sample numbers, it is vital to apply non-classical statistical approaches for data processing. Deep learning models are more effective; few efforts have lately made to identify PDAC, but the models are not developed successfully. This paper used an enhanced Convolution neural network (CNN) model to classify pancreatic decease at different stages accurately to clinical correction. The model has effective results compared to existing models.

Published: March 2022

Thymus algeriensis have been vastly utilized for intestinal disorders. The purpose of this investigation was to scrutinize the probable mechanism for its utilization in the spasm disorder. Aqueous extract of this medicinal plant (AqTA) was tested in vitro on rat and rabbit jejunum. The extract produced relaxation of rabbit jejunum. This relaxation does not depend on the adrenergic pathway, the AqTA induces inhibition irrespective of the presence or absence of adrenergic inhibitors. AqTA engendered a concentration-dependent (0.1-5 mg/ml) relaxation of carbamylcholine chloride (CCh) and K+ provoked tones in rat intestine with IC50 values of 2.06 Â± 0.26 and 3.55 Â± 0.48 (mg/ml) respectively. This extract likewise induced a dosedependent (0.1-3 mg/ml) rightward shift in the CCh and Ca++ dose-response curves. The AqTA alone has decreased more significantly the percentage of contraction of rat jejunum than the AqTA pre-incubated with atropine or hexamethonium then contracted with KCl; but there is no significant difference by those pre-incubated with methylene blue or L-NAME. When the intestine was pretreated with nifedipine and contracted by CCh, the antispasmodic effect provoked by AqTA with and without pre-incubation with nifedipine is statistically not significant. In conclusion AqTA acts possibly on the voltage dependent Ca++ channel and cholinergic receptors but did not act on adrenergic receptors, NO and guanylatecyclase pathway. This investigation may explicate some of its traditional utilization in gut illnesses.

Authors: Sveklina T. S. , Tyuryupov M. S. , Medvedeva V. A. , Shustov S. B. , Kuchmin A. N. , Kozlov V. A.
Published: March 2022

Objective. To determine the presence or absence of the effect of therapy with renin-angiotensin-aldosterone system (RAAS) blockers in patients with COVID-19.

Design and methods. We examined 57 patients who were treated in a medical unit at the FGAU CEC “Patriot” in the period from October to November 2020, with the diagnosis of “New coronavirus infection” and differed in the prescribed antihypertensive therapy. In group 1, drugs that affect the RAAS were used to treat hypertension before COVID-19 onset and during the treatment of COVID-19. In group 2, other drugs were used as the main antihypertensive agents before and during treatment for COVID-19. The severity of pneumonia in patients according to the results of computed tomography was 1–2. The patients were monitored for anthropometric indicators, body temperature, and laboratory data.

Results. Groups 1 and 2 are comparable, differing only by height, but not by body mass index. The duration of treatment in group 2 was 1–2 days shorter than in group 1, but the result is not statistically significant due to the small sample. Thus, the hypothesis that differences between previous and ongoing antihypertensive therapy throughout the COVID-19 treatment period may affect the course and effectiveness of treatment has not been confirmed.

Conclusions. Concomitant antihypertensive therapy with RAAS blockers does not alter the course of COVID-19 infection in patients. The duration of COVID-19 in patients receiving RAAS system blockers may be one day longer than for patients receiving other antihypertensive therapy.

Authors: Novikova L. B. , Latypova R. F. , Novikov A. I.
Published: March 2022

Background. Acute stroke is a highly specific neurological symptom in the acute phase of COVID-19. Hemorrhagic stroke (HS) is an infrequent, but life-threatening complication of COVID-19.

Objective. To analyze etiopathogenetic factors and the course of HS associated with COVID-19.

Design and methods. A retrospective analysis of 27 medical histories of patients with HS associated with COVID-19 (the main group) and 14 medical histories of patients with HS not related to COVID-19 (the control group) was performed. In the main group, COVID-19 was confirmed by the positive polymerase chain reaction method. HS developed before COVID-19 symptoms in 10 (37,04%) patients and after 4–16 days of COVID-19 symptoms onset in 17 (62,96%) patients.

Results. Our study indicates significant differences in blood pressure (BP), respiratory system parameters, laboratory data, neuroimaging data in patients of the main and control groups. Coagulopathy, thrombocytopenia, hypoxia, and the renal and hepatic failure play a significant role in the development of HS associated with COVID-19 compared to the classic HS (without COVID-19), where hypertension seems to be the important. At the same time BP is significantly lower in the main group.

Conclusions. The etiopathogenetic factors and the course of HS associated with COVID-19 require pathogenetically different therapy compared to HS without COVID-19.
Ekstremistki, które nie poddały się WRON-ie. Historia łodzianek internowanych podczas stanu wojennego
Authors: Orman Kamila
Published: March 2022

After the imposition of martial law, approximately 10 thousand activists were interned on the charge of anti-government subversion. Among them, women dissidents who participated in Workers’ Defence Committee (KOR), Young Poland Movement (RMP), Confederation of Independent Poland (KPN) and co-founded the Independent Self-governing Trade Union ‘Solidarity’ (NSZZ „Solidarność”). Their involvement with the opposition resulted in years of repression – arrests, searches and seizures, job loss, constant surveillance. Nevertheless, at no point either before or after their internment, did the female Łódź activists succumb to the intimidation of the authorities. Upon release from confinement, most of them continued their conspiratorial work. After 1989, the internees engaged in either political or social activity or turned to family life and professional career. Undoubtedly, each and every one of them demonstrated courage and determination in their fight against the communist authorities of Polish People’s Republic (PRL). No sacrifice would have sufficed to stop them on the path they had chosen.

Published: March 2022

The text presents the approaches of seven women who while working or cooperating with prison officers conduct theatre activities in prisons or probation centres. Among them there are ‘uniformed women’ – the functionary and the nun; ‘institutionalized ones’ – those professionally involved with the theatre – the actress, the playwright and the director and the community workers who after completing drama studies devoted themselves to community arts projects. ‘My heroines’ following in Antygona’s footsteps introduce into prisons, which are the structures of oppression, the element of revolt without a riot. Their ‘disobedience’ (after Jacques Derrida) manifests itself in as different ways as their attitudes.
CIDADE E CIDADANIA (BRASÍLIA, TRAJETÓRIA DE UMA INVENÇÃO)
Authors: Gorovitz Matheus

Lúcio Costa dá sentido ao reunir o público e o privado sem hierarquia e subordinação transparece no risco onde os eixos se cruzam e se completam em pé de igualdade. O confronto com o risco alternativo no processo de elaboração evidencia as razões da linearidade axial adotada. O trabalho perpassa por marcos das tradições ocidentais com o intuito de pensar se há o fato de desenho não ter superado as contradições e a atitude de indiferença prevalecer, insistindo em subverter e mutilar a cidade, evidencia o caráter utópico do projeto: a aspiração de humanizar o viver permanece ainda como promessa.
ARQUITETURA HOSTIL (SQN 213)
Authors: Ferreira da Silva Felipe Matheus
Published: March 2022

O artigo tem a finalidade de contribuir para o debate sobre o conceito de arquitetura hostil. O termo ganhou visibilidade na opinião pública brasileira depois do protesto simbólico do padre Júlio Lancellotti, em fevereiro de 2021, e da consequente proposta legislativa de vedação do emprego de técnicas dessa natureza no Estatuto da Cidade. Para analisar o lado menos ostensivo da arquitetura hostil, foi empreendido um estudo de caso sobre a sua aplicação na Superquadra Norte 213.

OBJECTIVE:Metabolic syndrome (MetS) can lead to fatal complications, including cardiovascular disease. Emerging evidence suggests has emerged that increased fruit and vegetable intake and decreased intake of saturated fats, simple sugars, and processed foods can improve cardiovascular health. Anthocyanins (color pigments) have anti-inflammatory and antioxidant capacities but are of low bioavailability. In this systematic review and metaanalysis, we investigate the possible beneficial effects of the intake of berries high in anthocyanins on MetS risk factors. We also investigate the influences of high-density lipoprotein (HDL), lowdensity lipoprotein (LDL), triglycerides (TG), and total cholesterol (TC).METHODS:We identified 2,274 articles from PUBMED and EMBASE following a search input designed to include studies of interest of these, 21 met inclusion criteria.RESULTS:The studies showed an overall reduction in low-density lipoprotein (p=0.04). Increases in HDL were found with cranberry and freeze-dried berry intake during a 4-6-week intervention. No statistically significant findings were detected for fasting glucose, Hb1Ac, insulin levels, blood pressure, oxidized LDL (OX-LDL), BMI, and overall HDL.CONCLUSIONS:We conclude from this systematic review and meta-analysis that increased berry intake improves MetS key risk factors and reduces the risk of cardiovascular disease. Pronounced effects were apparent for concentrated berry products, such as freeze-dried strawberries.

COVID-19 is deepening pre-existing inequalities. Emerging research suggests that people with disabilities across the world have experienced various rights violations and been disproportionality affected by the health, economic and social impacts of the pandemic and responses to it. The aim of this research was to better understand how people with disabilities who are often excluded from research have experienced the evolving COVID-19 pandemic in Bangladesh and Nepal. In order to better understand how it has affected some of the most marginalised groups of people with disabilities, this study used in-depth qualitative research to focus on people with intellectual, psychosocial, deafblindness and other multiple impairments.
Social Norms, Gender, and Serious and Organised Crime in Albania and Kosovo
Authors: Herbert Siân
Published: March 2022

This rapid literature review explores the evidence about social norms, gender, and serious and organised crime (SOC) in Albania and Kosovo. There is limited literature that explores this exact question, as historically, gender has rarely been associated with organised crime (Amerhauser, 2020), therefore beyond a few focussed texts, this query also brings together findings from related literatures on: gender and organised crime (more generally); gender norms in Albania and Kosovo; and organised crime in Albania, Kosovo, and in the broader region of the Western Balkans. This paper is not comprehensive of all of the issues related to this question, but is illustrative of the most commonly discussed issues.

Published: March 2022

This study aims to determine the content of active compounds of secondary metabolites and antibacterial activity of secondary metabolites from a maceration of turmeric leaf (Curcuma longa Linn.) and kaffir lime leaf (Citrus hystrix) against Escherichia coli (E. coli). Each sample of kaffir lime leaf and turmeric leaf was extracted by maceration method using 96% ethanol solvent for 3 x 24 hours and the solvent was changed every 1 x 24 hours, then the filtered filtrate was thickened using a rotary evaporator. The phytochemical screening test was carried out by qualitative method using chemical reagents. The antibacterial activity test of the extract of the combination of turmeric leaves (Curcuma longa Linn.) and kaffir lime leaves (Citrus hystrix) used the Punch Hole Diffusion method with various concentrations of 20%, 40%, 60%, 80%, and 100%. The results showed that the combined extract of turmeric leaf (Curcuma longa Linn.) and kaffir lime leaf (Citrus hystrix) contained secondary metabolites in the form of flavonoids, alkaloids, steroids, tannins, and saponins. The optimum zone of inhibition to inhibit the growth of E. coli produced was 9.73 ± 0.78 mm. Overall, it can be concluded that the combined extract of turmeric leaf (Curcuma longa Linn.) and kaffir lime leaf (Citrus hystrix) has potential as an alternative to antibacterial active compounds.
