The production of the basalt-based composite material was carried out using compression moulding. The selected materials basalt rock, bronze chips, cast-iron chips, glass fibre and phenolic resin were crushed into powder and sieved with a sieve size of 150microns. An optimization model based on the rule of mixture was developed to obtain the volume fractions of the constituent materials and a factorial Design of three levels and three factors was applied to obtained different sets of manufacturing parameters for the production of the samples using MINITAB 18 software. Twenty-seven samples with dimension of 20mm diameter and 8mm height were produced based on the formulation obtained from the optimization model and factorial design, this samples were subjected to tests. The test result shown that the basalt-based wear rate ranges from 9.0X10-5 to 1.52x10-4g/m and by volume is from 4.04x10-12 to 7.97x10-12m3/Nm. The density of the composites ranges from 2382.76 to 2781.33kg/m3. The Thermogravimetric Analysis (TGA) result shown that the basalt-based composites is thermally stable up to a temperature of 5300C before thermal degradation started setting in and Differential Thermal Analysis (DTA) result shown that the highest mass degradation occurred at a temperature of 6000C. Hence the basalt rock is a good material that can withstand high temperature.

There is a quest and a sustained interest in environmentally friendly and sustainable building materials, for farm structures, as well as for general building construction, due to the availability of suitable industrial materials, by-products and wastes, to which additional value can be provided in their utility and management. The suitability of using wood shavings as partial replacement for fine aggregate in concrete production, with cassava starch and sodium chloride (NaCl) as admixtures, was investigated in this study. The concrete was produced with a mix ratio of 1:2:4, and partial replacement of the fine aggregate with wood shavings, at the rate of 0%, 1.25%, 2.5%, 3.75%, 5%, 6.25%, and 7.5% (wt. of fine aggregate). Furthermore, cassava starch (2% by weight of the cement) and NaCl (1% by weight of the cement) were used as admixture. Results obtained from the slump and compression tests depicted that, the slump of the fresh concrete and the compressive strength of the hardened concrete decreased non-linearly as the volume of wood shavings increased from 0% to 7.5%. The findings of this study revealed that both the cassava starch and NaCl increased the slump properties of the fresh concrete, and the compressive strength of the hardened concrete, irrespective of the volume of wood shavings incorporated. Additionally, the results depicted that the hybridized concrete produced with wood shavings, cassava starch and NaCl, had a higher compressive strength, when compared to the hybridized concrete produced with wood shavings and cassava starch only. Results obtained from this study had affirmed that low volume of wood shavings, cassava starch and NaCl can be used for the production of plain concrete for farm structures, mostly in areas where metallic reinforcement materials are not required.

The beginning of year 2020, the COVID-19 pandemic has hit all parts of the world, including Indonesia. This pandemic is caused by the SARS-CoV-2 virus and its various mutants and variants. This virus is known to attack the human respiratory system. The virus is transmitted through direct contact or through the air, which makes it Airborne. Even though there are variety of disinfectants that can prevent transmission between humans, not many can maintain the sterility of the room continuously. Disinfectants on its own have a level of danger to humans when exposed at a certain doses and for a certain time. Ozone (O3) is known as the most potent disinfectant. This paper is intended to determine the appropriate placement and dose of Ozone when used in a meeting room at an office, which is widely known as the centre of the Covid-19 spreading in Jakarta, using the Prevention through Design (PtD) method. In designing the right Ozone placement, the existing air system will also be studied. The calculation of the levels of O3 is based on mathematical calculations. The result from this study shows that the positioning and dosing control of O3 can effectively disable/kill the virus, while still considered safe for humans, so that productivity will be maintained.

The increased prevalence of hypertension and dyslipidaemia specifically in the young population necessitates the identification and quantification of literature gaps in the different phases (awareness, screening, diagnosis, treatment, adherence, and control) of patient management in the UAE for better clinical outcomes. This semi-systematic review identified relevant articles through structured and unstructured searches. Studies on adult populations published (2010-2019) in English and providing data on phases of management of hypertension or dyslipidaemia in the UAE were retrieved. Quantitative data were represented as weighted means. In total, 11 studies on hypertension and six studies on dyslipidaemia were included for the final analyses. The pooled prevalence of hypertension and dyslipidaemia was 24.8% and 43.8%, respectively. The estimates indicated that a few patients (range: 6.8%-17.3%) were aware of their condition, where 63.2% and 49.3% were screened for hypertension or dyslipidaemia, respectively. Approximately two-thirds of patients were on antihypertensive and lipid-lowering medications, whereas 68.4% of patients were adherent to antihypertensive treatment. No data are available on adherence to dyslipidaemia treatment. Control of both risk factors was poor (range: 12.7%-27.8%). The semi-systematic approach identified limited to no data on different phases of management of hypertension and dyslipidaemia, indicating a need for generating country-specific real-world data.

Background: Tracheal stenosis is a narrowing condition of the trachea that can lead to life threatening breathing complications depending on the extent of reduction in the airway diameter. This condition affects not just the lung’s performance to draw air during inspiration but also the flow behavior in the bronchi generations. Methods: Computational simulations were performed in idealistic healthy and stenosed tracheobronchial models of adult and infant airways consisting of the trachea and mainstem bronchi alone. Effect of 70% reduction in trachea diameter was investigated for both models using Ansys Fluent. Results: We realized that while airflow developed along the center in the healthy model, flow in the stenosed tracheae moved in a jet-like manner, forcing its way across the airway tract with velocity 5 m/s greater than that in the healthy airways. This high jet-like flow at the center in the stenosed tracheae led to high flow impact at the bronchi bifurcation. Consequently, wall shear stress at the bifurcation was high in both stenosis cases. Conclusion: This study shows that tracheal stenosis potentially leads to high flow impact and wall shear stress at the bifurcation of mainstem bronchi, and this effect will have severe consequences in infants than adults.

Nutritional rickets caused mostly due to Vitamin D deficiency. It is has been declared a public health problem for both adults and children worldwide. Wheezy chest and related allergic diseases are the leading causes of morbidity in children. The objective of this study was to investigate the potential relation of vitamin D deficiency and wheezy chest in children. Case series study was conducted during the period from January to March 2021. 50 children aged 3 months to 24 months were selected randomly from children admitted to department of pediatric in Al-bieda medical center. Out of the total 56% were males, 70% were exclusively breastfed in their first 6months of life. 68% have positive family history of chest allergy. (64%) developed first attack of wheezy chest before 6 months and recurrent attack were observed in (52 %). Vitamin D deficiency was observed in 62% of the wheezy patients with 56% of cases had minimum sun exposure. Early onset was more common in males. Late onset wheezy chest was more common in children lives in houses with bad ventilation in compare to those who lives in better conditions in conclusion, vitamin D deficiency was common finding among children included in our study. It was associated with minimum sun exposure and early weaning. However, larger follow up studies are required to elucidate the effect of vitamin D supplementation on different parameters of asthma severity, its potential therapeutic benefit on children suffered recurrent wheezy chest attacks

Since the evolution of human being communication has played an important role in trade and business. Advancement in methods and medium of communication has given wings to marketing of goods and services in tourism as it is an information intensive industry. We have experienced diverse employability of Internet Communication Technologies (ICT’s) which has given rise to Social Media as an important tool of marketing communication. This conceptual paper argues over the nature of sustainability of Social Media platforms and its constituent elements. Tourists are actively participating in creating marketing content on social media platforms along with destination marketers and promoters. User Generated Content (UGC) on social media platforms have become important source to help tourists in making a purchase decision for online and offline tourism products. Social Media allows user to upload, share, interact and make collection of user controlled data which serves as a guide for interested tourists. It is a platform where both tourism destination marketer and tourists become an information generator, disseminator and user. The paper applies the concept of sustainability on social media as a marketing communication tool and brings out the insights of social media to be called as a sustainable tool. The available literature indicates that dimensions of sustainability (environmental, economic, and social) are applicable on social media platforms in terms of generating online content which is less expensive, environment friendly and self-sustaining.

Introduction: Eosinophilia is often identified as part of a complete blood count (CBC) done either routinely or as part of an evaluation for a particular symptom complex. Association of eosinophilia with anaemia most commonly denotes the presence of parasites infection. Parasites relationship with anemia and eosinophilia has been rarely reported due to limited health care access, especially in adult age group. Materials and Methods: A retrospective study was started after obtaining the approval from the ethics committee. Patients with parasitic Infections associated with eosinophilia were correlated with their hemoglobin concentration. This study was conducted during the period of January 2020 and March 2021 in Saveetha Medical College and Hospital, Tamil Nadu. Hematological parameters like hemoglobin, eosinophil count and Absolute eosinophil count were obtained using Sysmex -XN 1000 automated analyser. Results: Out off 83 patients with parasitic Infections associated with eosinophilia, on gender distribution we found 49 were male and 34 were female. 25 patients were anemic and 58 patients were non anemic. On grading of anaemia, according to WHO classification 58 cases were grade 0 (not anaemic), 18 cases were grade l, 6 cases were grade ll and only one case was grade lll. Conclusion: Our study concludes, eosinophilia act as marker for parasitic infections. Degree of anaemia and increased eosinophil count in peripheral blood smear denotes severity of parasitic Infections especially in helminths infection.

Corona-virus pandemic has become a major health problem worldwide. It evokes mental health disorders affecting population globally especially the pregnant women and associated with adverse maternal and fetal outcomes. Therefore, we aimed to assess anxiety and depression among pregnant women during this lethal outbreak of corona-virus. We conducted a cross-sectional study at Hamdard University Hospital, Karachi from October 2020 to February 2021. A total of 120 pregnant women were included in this study. Psychological Impact was assessed using questions from DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure for Adults and data was analysed using the software IBM SPSS Statistics 26. We found that more than half (67.5%) of pregnant women had developed mental health disorders during this pandemic and there is a need to reform policies for the care and counselling of pregnant women as they are particularly susceptible.

Genetically modified genetically plants pass through diverse domestication from wild species and many generations of selection by humans for desirable traits. These genetically modified genetically crops are diversely produced in different industries to decrease the attack of pests by transferring different combinations of genes through advanced technologies. The gene of interest is inserted into the crop's genome using a vector that exhibits the biological carrier genes. Bacillus thuringiensis (Bt) corn is the genetically modified corn that produces most of essential proteins necessary for human body also secrete toxic to certain insect pests. Genetically engineered cotton is the most evolutionary step to replace the traditionally used methods for production of cotton. Genetically engineered canola has been produced by inserting through high technology methods. Protein samples can be obtained from genetically modified crops can be resolved with the one-dimensional SDS-gel electrophoresis. Genetically engineered crops have many advantages, and the benefits of being able to use herbicides that would cause unacceptable phytotoxicity to a crop are clear.

In PIM process, the molding stage is a critical step for the fabrication of sound parts without cracks and distortions. So, this step requires specific rheological behavior. Rheological analysis can be made to quantify the stability of the PIM feedstock during molding process. In this study, an experimental rheological study has been performed to evaluate the effect of composition binder system on the stability of titanium alloy powder injection molding (MIM) feedstock in term of shear sensitivity and activation energy. The rheology properties of feedstock were measured via capillary rheometer machine. The viscosity of feedstocks was measured at temperature of 120C, 130C, 140C and 150C under different five (5) different constant load at 20N,30N,40N,50N and 60N respectively. The results show that the addition of binder component which possess low molecule weight has reduce flow behavior index value and increase flow activation energy value of feedstock. However, the feedstock produced will get a problem such powder-binder separation and high residue stress which will defect the molded part component. The formulation binder system PEPS 4060 is the best feedstock for titanium alloy MIM process because it has moderate value of flow sensitivity index and flow activation energy value and higher value for mold ability index.

Osler-Weber-Rendu syndrome (OWRD) is a rare vascular dysplasia of genetic origin and of autosomal dominant transmission, the pathophysiology of which involves the vascular endothelial growth factor (VEGF), a major growth factor of angiogenesis. Bevacizumab is an anti-VEGF monoclonal antibody that has demonstrated its interest in this indication. Two patients, with a personal and familial history of haemorrhagic syndrome, who had an OWRD detected in recurrent epistaxis, cutaneous-mucosal telangiectasia, and complicated visceral arteriovenous malformations with an iron deficiency anemia. Due to the persistence of the symptomatology despite a transfusion support, the treatment with bevacizumab was started and allowed a favorable outcome. Bevacizumab appears to be very well tolerated and represents a therapeutic advance in OWRD.

Background: There is a lack of studies on workplace safety in Africa and in particular as a Democratic Republic of Congo (DRC). The present study was designed to explore perceptions of the workers of the textile in DRC. The aim was to analyze how different risk perceptions can influence the behavior of security and health related to work. Methods: A cross-sectional study was conducted on a representative sample of textile Workers Company in DRC. Data collection (N= 228 subjects) was performed using a self-administered questionnaire. The survey questionnaire was developed using validated questionnaire for the assessment of work safety scale, the model of work organization and safety and performance behavior, supplemented by the European working conditions surveys. The internal consistency coefficients (Alpha de Cronbach) for reliability analysis were calculated separately for each measurement. Only scales with reliable internal consistency (Cronbach alpha index >= to 70) were selected in our analyses. The relationship between perceptions and work-related accident was analyzed by an ANOVA-one-way analysis for independent samples. For each scale, a correlation of Spearman was calculated. A logistic regression model was used to assess the association between the accident and the predisposing factors for the different scales of the questionnaire. Results: The correlations in this study are highly significant for different scales. The strongest correlations are between the perceptions of the Management Safety Practice and Supervisor Safety. The results showed a difference in the frequency of accidents according to workers' safety perceptions. Workers who were not victims of an accident presented higher mean scores for Job safety, Management safety practice, Safety knowledge and SCRD. The study shows that the accident rate is significantly related to Job safety (OR= 2,1), to Management safety practice (OR=2,9). Safety knowledge (OR=0, 37) and the SCRD (OR=0, 30) have protective effect. Conclusion: The present study shows that the perception of workers influences their health-safety behaviours at work. It’s highlighted the influence of occupational safety knowledge, the management system on the occurrence of the work accident. The results provide valuable guidance for policy makers, researchers and practitioners to identify mechanisms to improve workplace health and safety.

The existence of the internet not only has positive impacts, but also has negative impacts, one of which is the rampant hate speech that is spread through social media. The government then issued Law No. 11 of 2008 concerning Electronic Information and Transactions as amended by Law No. 19 of 2016, which regulates the criminalization of hate speech conducted via electronic media. Nonetheless, even though there have been criminal threats against acts of hate speech through cyberspace, the number of cases of hate speech that are handled by the police has actually increased from year to year. The purpose of this paper is to find out how the influence of social changes in the criminalization of hate speech through electronic media and the effectiveness of criminalization of hate speech through electronic media as an effort to tackle the rise of hate speech in cyberspace. This research uses normative legal research method. The results of this study explain that social changes related to the way of sharing information via electronic media have a real impact on applicable law in Indonesia with the existence of regulations regarding the criminalization of hate speech through electronic media. However, since the enactment of this regulation, the number of acts of hate speech through electronic media has increased from year to year. Therefore, the criminalization policy must pay attention to the principle of subsidiarity, meaning that criminal law must be placed as a last resort in overcoming crimes using a penal instrument, not as the main effort. Other efforts are needed that should be prioritized apart from punishing the perpetrators of criminal acts.
