Authors: Sidiq Fahmi
Published: January 2022

The cultivation technique of land kangkung (Ipomoea reptana Poir) which is practiced by farmers is a non-machine technique. Farmers' cultivation techniques are tillage, seed dispersal, fertilization and harvesting at 40 days after planting. The purpose of this study was to determine the internal and external factors that influence the development of organic kale farming, and to determine the appropriate development strategy for organic kale farming. Data collection methods used are interviews, observation and literature study. The results of this study indicate that the internal strength factor in the development of organic kale farming is the availability of adequate organic fertilizer, while the weakness is the weakness of the product produced cannot meet consumer needs and organic labels. The external factor is the opportunity for organic kale to be marketed online, while the threat is the sale of more and more non-organic vegetables at lower prices.

Published: January 2022

The modified Kudryashov approach along with the conformable derivative is used to find a variety of askew wave solutions, with some free parameters, of the space-time fractional modified KdV equations. We study the wave solutions of the aforesaid mKdV equations that are obliquely propagated to consider the behaviour of physical issues in water waves and other fluids. The graphical depiction of these solutions is given via Mathematica for better understanding. Moreover, apart from the physical implication, these solutions may be helpful for an upgraded understanding of numerical solvers to compare the accuracy of their results and performances of wave dynamics as observed in science and engineering.

Authors: ÇAYIR HAŞİM
Published: January 2022

In this paper our aim is to get the general structure equation which covers previously acquired structures. In this context this paper consists of three main sections. In the first section, we define the general F_(a,λ) (K,T)-structure satisfying aF^K+λ^r F^T=0,(F≠0,K≥3,T≥1 and (K≥T),a and λ are non zero complex numbers, r some finite integer) on manifold M^n and studied to give some special examples. The second part, we find the integrability conditions by calculating Nijenhuis tensors of the horizontal lifts of the general F_(a,λ) (K,T)-structure satisfying aF^K+λ^r F^T=0. Later, we get the results of Tachibana operators applied to vector and covector fields according to the horizontal lifts of the general F_(a,λ) (K,T)-structure in cotangent bundle T^* (M^n). In addition, we have studied to show the purity conditions of Sasakian metric with respect to the horizontal lifts of the structure. In the final section, all results obtained in the second section were investigated according to the complete and horizontal lifts of the general F_(a,λ) (K,T)-structure on tangent bundle T(M^n).

BEHAVIOUR OF METHYLCELLULOSE GEL AT HIGHER CONCENTRATIONS FOR CLEANING OF ACRYLIC PAINTED SURFACES
Authors: KANTH ADITYA PRAKASH , SINGH MANAGER R.
Published: January 2022

This research demonstrates the application of methylcellulose (MC) as a gelator for cleaning acrylic painted surfaces. Highly thickened methylcellulose gels were predominantly tested to investigate the residue left after cleaning. The function of methylcellulose as a molecular trap was also assessed to minimize the clearance issue. The presence of residue, the efficacy of the methylcellulose as a cleaning agent and its physical impact on the paint surfaces were investigated using a digital microscope in normal, raking, and ultraviolet lights. Scanning electron microscopy (SEM), coupled with energy-dispersive X-ray spectroscopy (EDS) was used to study the compositional and topographical changes on the paint surface. Fourier transform infrared spectroscopy (FTIR) was performed in attenuated total reflectance (ATR) mode to observe the presence of residues after complete removal of the gelling agent. The experimental results indicated a minimum interaction of methylcellulose on the paint surface as the concentration increases in the gel formulation. The super-thickened hydrogels also worked like molecular traps useful for removal of soiling from the painted surfaces.

Osteomyelitis continues to be a major concern when orthopedic surgery is performed. Orthopedic infections have an incidence of 5% to 10% but their management proves to be quite difficult due to both biofilm formation and limited access of the drug to the infected area when systemic treatment is employed. The aim of the study was to optimize the synthesis process of a gentamicin loaded poly(-lactic-co-glycolic) acid (PLGA) based biodegradable composite by varying parameters that affect both efficiency encapsulation and nanoparticle size. Furthermore, a kinetic study was conducted to study the biodegradation process of the polymer. Gentamicin loaded PLGA nanoparticles were obtained using the double emulsion technique which allows the variation of several factors such as gentamycin concentration, PLGA concentration, buffer concentration and stirring speed. Out of the four factors evaluated, gentamicin concentration had the highest impact on both encapsulation efficiency and nanoparticle size. A few relevant interactions between factors were also registered.

Chlorophyll-a is the pigment whose concentration is an important indicator for the development of microalgae biomass. This study aims at evaluating the concentration of chlorophylls in the biomass of granular activated algae, using acetone and 90% ethanol for the extraction procedures applied. Concentrations of chlorophyll a, b and c were determined by applying three calculation types: methods proposed by Jeffrey and Humphrey for the extracts in acetone, Ritchie method for ethanolic extracts, and monochromatic method with acidification for ethanolic extracts. Experimental findings show that the solvent 90% ethanol is more efficient than acetone for extracting chlorophyll from biomass of granular activated algae. Also, by comparing results obtained by the two methods proposed for ethanolic extracts, it was found that the values obtained through the acidification method are influenced by the volume of hydrochloric acid added to the organic chlorophylls extract.

Published: January 2022

Competency in referral writing skill is needed by doctors for which they are never trained. Although there is a lot of work done about improvement of consultation letters still priority is not given. There must be a course for teaching and learning medical referral writing skills to students along with the assessment. Currently there is such tool to assess the way communication letter are written. An 18-point assessment scale has been developed through Delphi technique to increase the quality of referral letters. The objective of the present study was to design a structured Performa for writing referrals, validated by 7 participants using Delphi. Results were finalised after the acceptance of structured referral by selected participants through Delphi. The response rate was 70%. The validity and interrater reliability were calculated using SPSS25. The Cronbach’s alpha was 0.7 and Kappa was 0.3. Both were statistically significant. The designed Performa for writing referrals, with its inter-rater reliability calculated, is best for writing effective and structured referrals. The study further recommending training junior doctors in making proper referrals.

Published: January 2022

Background: Streptococcus pneumoniae is a major cause of morbidity and mortality worldwide. With the emergence of penicillin-resistant S. pneumoniae (PRSP), treatment has become challenging. The Clinical and Laboratory Standards Institute (CLSI) in 2008 revised its guidelines for S. pneumoniae and recommended separate penicillin breakpoints for meningeal and non-meningeal strains. Similar to penicillin’s, resistance to other classes of antibiotics has emerged globally.

Objective: The objective of this study is to determine the trend of resistance to antimicrobials in S. pneumoniae infections and the impact of new CLSI guidelines on penicillin susceptibility among meningeal isolates.

Methodology: Twenty-four years (1993-2016) data from S. pneumoniae isolates and their antimicrobial susceptibility was retrieved from the computerized database. Data was divided into two groups for analysis, pre-2008 and post 2008.

Results: Penicillin resistance remained unchanged in non-meningeal isolates during both study periods. A significant rise in penicillin resistance in meningeal isolates was observed in the second period 2008-2016 (2.9% vs 36.2%). High resistance rates were observed for co-trimoxazole, tetracycline and erythromycin. Increased trend of multi-drug resistant (MDR) strains were also noted, from 11% in 1999 to 36% in 2016.

 Conclusion: The emergence of MDR strains is evident from our dataset. It seems like the rise in PRSP in meningeal isolates is due to revised CLSI guidelines. Overall low resistance to penicillin in non-meningeal isolates and no resistance to ceftriaxone is encouraging and will assist in drafting local guidelines. Cautious use of antimicrobials are essential to reduce further emergence of antimicrobial resistance in indigenous isolates.

Published: January 2022

The artery of Percheron is a rare variant of the posterior cerebral circulation. It is characterised by a single arterial trunk that supplies blood to bilateral paramedian thalami and rostral midbrain. Its occlusion can have a very wide range of presentation, and initial imaging including CT of the head maybe normal. Diagnosis and eventual treatment is usually delayed. We describe the case of an elderly man who presented with loss of consciousness, aphasia, and bilateral lower limb weakness. He was diagnosed with bilateral thalamic infarction due to the occlusion of the artery of Percheron only after an MRI of the brain was performed. Despite treatment his symptoms did not resolve completely.

Authors: Rehman Rehana , Tariq Sundus , Tariq Saba
Published: January 2022

Medical profession deals with human interactions and ability to empathize improves clinical interactions as well as brings out good clinical outcomes. This has led to increasing interest in the importance of Emotional Intelligence (EI) for effective clinical practice. EI integrates the important aspects of interpersonal and intrapersonal relationships to promote self-management skills like adaptability, control of temperaments and tension free states, which have a profound effect on the academic performance of students. There has been substantial evidence proving that being emotionally intelligent can help individuals excel through life transitions starting from school to college, and later into to the working world. There are many studies in the literature that examine the correlation between EI and academic achievement in different education levels which signify importance of EI levels to predict “students who are in need of guided intervention”.

Authors: Ortiz Magdaleno Marine , Romo Ramirez Gabriel
Published: January 2022

Substance use disorders, related to mental health issues can lead to oral pathologies. The purpose of this case report was to identify the oral conditions and manifestations in a 28-year-old male narco-dependent schizophrenic who smoked tobacco and marijuana. In intra-oral clinical exploration, poor oral hygiene, excessive tartar formation and dental plaque were observed, and the diagnosis of severe chronic periodontitis was established. The choice of a treatment plan in such patients is complex because the consequences of an invasive treatment can aggravate the psychological state and emotional stability leading to a negative effect on behaviour and mental health due to edentulism. The effects of excessive drug consumption related to schizophrenia can cause poor oral hygiene habits leading to oral pathologies and the loss of teeth.

Authors: Wardani Dewi Kusuma , Wijayanti Ayu Pratiwi
Published: January 2022

This study aims to determine the effect of corporate social responsibility on tax aggressiveness with firm size as moderation. The research method used is quantitative methods and secondary data using annual financial reports. The sample of this research is the property and real estate sector companies listed on the Indonesia Stock Exchange in 2016-2019. The results of this study indicate that corporate social responsibility has a positive effect on tax aggressiveness. Company size cannot moderate corporate social responsibility with tax aggressiveness. The conclusion of this study is that companies that disclose high CSR will have higher tax aggressiveness, because companies will attract public sympathy by disclosing broad CSR, to cover up the company's bad image with tax avoidance that has been carried out by the company. The existence of a large company size cannot affect the level of CSR disclosure. This is because large companies are not guaranteed to disclose broad CSR, where investors do not only look at how big the company is but also look at it from a financial perspective.
