Abstract
The objective of this work is to investigate the microstructure, composition and hardness of reactive titanium nitride coatings manufactured by Reactive Very Low Pressure Plasma Spraying (R-VLPPS) process. Pure titanium powder is injected into the plasma and a reactive gas is added to generate a reaction with the molten particles /vapors. Firstly the plasma-jet properties were analyzed by means of optical emission spectroscopy (OES). Then titanium nitride coatings were manufactured with a F4-VB low-power plasma gun under a working pressure of 150Pa. Investigations show that according to the radial position of the substrates compared to the plasma jet axis, the resulting coatings microstructures are different (mix of semi-molten particles, liquid spat, clusters and vapors). In addition, the coatings composition is modified with an evolution of TiN0.3 and TiN phase crystalline phases. Finally, the hardness of the coatings is examined.

Abstract
Plasma spheroidization utilizing a plasma spray gun has been demonstrated for water-atomized stainless steel SUS316L powder. The angular particles were successfully spheroidized, and the D50 size of particles were decreased from 35 μm to 24 μm with 9 kW of processing power and to 15 μm with 17 kW of processing power. It was found that the high processing power of 17 kW generates a significant number of fine particles with the size of under 1 μm. By contrast, the powder formed on low processing power of 9 kW has better flow-ability and low cohesiveness, suggesting that an appropriate processing power exists to form the spherical powder suited for additive manufacturing

Abstract
Thermal spraying technologies are widely used to fabricate quality thick metallic and ceramic coatings for various applications. In all sectors of the industry today, demands better, faster and cheaper methods of production, as it seems that manufacturing demands are ever-increasing. However, if the coating thicknesses below 50 microns are demanded as the result of economic or technological requirements, this often constitutes a challenge for the established thermal spraying processes. For this purpose, in the present work, an attempt has been made to deposit a thin metallic coating below 40 microns by thermal spraying through wire feedstock materials rather than using an expensive powder as feedstock. For a broad spectrum of copper (Cu) applications, Cu is deposited on the low carbon steel substrates using fast, easy and economical Wire-High Velocity Oxy-Fuel (W-HVOF) thermal spray system (trade name-HIJET 9610). As-sprayed coatings were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM) for phase and microstructural analysis respectively. Coating surface roughness and porosity were also measured. Adhesion strength tests were conducted to determine the bond strength of the as-sprayed coatings. Results show that the coating deposited by W-HVOF has acceptable properties and gain a direct economic advantage and time-saving process, often over established thin coating techniques like plating.

The study aimed to determine the adaptability of varieties and spacing of shallots in the rice fields of Sleman Regency to yield. The study used a Factorial Completely Randomized Block Design with 5 replications. The first factor is Variety (V), consisting of V1 = Head, V2 = Crok Kuning, and V3 = Srikayang. The second factor is Planting Distance (J) consisting of J1 = 15 x 15 cm2, J2 = 15 x 20 cm2, J3 = 20 x 20 cm2, and J4 = 25 x 20 cm2. The results showed that the spacing of plants did not significantly interact with all parameters. The use of shallot varieties significantly affected plant height at 3 and 5 WAP, tuber diameter, and stover productivity in wet and dry conditions but had no significant effect on the number of tillers per clump and stover weight per clump in wet and dry conditions. Spacing treatment significantly affected agronomic characteristics, especially weight of stover per clump in wet and dry conditions; stover productivity in wet and dry conditions, but had no significant effect on plant height 3 and 5 WAP, number of tillers per clump, and diameter. The Srikayang variety produced lower productivity than the Crok Kuning and Tajuk varieties. Increasing the width of the spacing will reduce the productivity of shallots.

Local beef is known for its low-fat content/lean meat. The fatty acid profile of beef could affect the meat quality, related to its texture, taste, and nutritional value. This study aims to determine the fatty acid profile of Rancah and Ongole Grade beef. This study used fourteen samples of meat from Rancah cattle 1.5 – 2.5 years, which were extensively reared with forage feed, and nine samples of Ongole Grade beef with forage and concentrate feeding as much as 2.5% dry matter of body weight. A fatty acid profile was analyzed from the longissimus dorsi muscle area, between the 12th and 13th ribs. The fatty acid profiles identified are saturated and unsaturated fatty acids (MUFA and PUFA). The fatty acid analysis used is the Gas Chromatography (GCMS) method. The data were analyzed descriptively and fatty acid composition differences of Rancah and Ongole grade beef were analyzed by T-test. The results showed that the fatty acid composition of Rancah and Ongole grade beef is relatively the same as the beef of other breeds. Saturated fatty acid in Ongole Grade beef is higher than Rancah beef, but the content of unsaturated fatty acids, PUFA/MUFA: SFA ratio in Rancah beef is higher than Ongole Grade.

Published: October 2022

ABSTRACTComposite is a tooth-colored filling material that can change color by extrinsic staining such as coffee, tea and cuko pempek. Abrasive toothpaste can reduce stains but increase surface roughness. This study aims to determine the effect of the type of toothpaste for brushing on the formation of stains caused by coffee, tea and cuko pempek. This research is a quasi-experimental with pre and post control group design. 39 composite discs with a diameter of 1 cm and a thickness of 5 mm were prepared and divided into several groups, 1 group of negative control without treatment, 3 groups of immersion. Each immersion group was divided into 4 brushing groups, namely without brushing, brushing without toothpaste, brushing with abrasive paste and brushing with non-abrasive paste. Pre and post treatment discs were photographed and color changes were assessed using the CIE L*a*b and E system. Friedman, Kruskall Wallis and Mann Whitney U non-parametric analysis test was used to compare color values and color differences within groups and between groups. Based on this study, it can be concluded that there were significant color changes before and after the soaking treatment with coffee, tea and cuko pempek. The color change in coffee was significantly greater than that of tea and cuko pempek. There was no significant difference in color change between tea and cuko pempek. Conclusion: Brushing with toothpaste Keywords: composite; coffee; tea; cuko pempek; CIE LAB

Published: October 2022

It is a procedure where NICH is modified with basic repair, 2 stitches approximating inguinal ligament with conjoint tendon. Hundred patients were operated between April 2012 to April 2022 by modified NICH technique. All were primary uncomplicated cases of inguinal hernia. Modified NICH procedure for inguinal hernia takes care of recurrence better than any other procedure for inguinal hernia. Though NICH is a good modification of tension - free Lichtenstein procedure for inguinal hernia but modified NICH further improves the results specialty the recurrence. Modified NICH hernioplasty gives added advantages of repairing posterior inguinal wall which directly influences the recurrence rate. In our series of 100 cases no post – operative recurrence was noted. Though the series described here is small so more cases and more time is required to further confirm the results.

Sunscreen Protection Against Visible Light: Is It Needed?
Authors: Dewi Dian Andriani Ratna 
Published: October 2022

ABSTRACT Ultraviolet radiation and Visible light (VL) have biological effects on the skin. VL causes erythema in light-skinned individuals and pigmentation in dark-skinned individuals. Broad-spectrum sunscreen protects skin against ultraviolet radiation but does not adequately protect against VL. The purpose of this study was to analyze the biological effects of visible light (VL) and the choice of sunscreen that can protect it. The research method used in this study is a qualitative descriptive method. The type of data used in this study is qualitative data, which is categorized into two types, namely primary data and secondary data.The protection provided by organic (mineral) and inorganic sunscreen filters can prevent skin damage due to ultraviolet radiation, but does not provide protection against VL. Only tinted sunscreens that use formulations of concentrated iron oxide and titanium dioxide can provide protection against VL. Various steps have been taken to provide photoprotection against VL. There are many sunscreens available that combine percentages level of iron oxide and titanium dioxide pigment to suit all skin types. This tinted sunscreen is beneficial for melasma and post-inflammatory hyperpigmentation and photodermatosis induced by VL.

Published: October 2022

Eclampsia is a life threatening obstretic emergency, the second leading cause of maternal death in Bangladesh. The high maternal morbidity and mortality in Eclampsia is related to multiple or recurrent seizures mostly. Magnesium Sulphate (MgSO4) is the gold standard drug to control and prevent recurrent fits. To compare the occurrence of recurrent seizures with loading dose and standard regimen of MgSO4 (Loading plus maintenance dose). This prospective comparative study was carried out in Department of Obstetrics & Gynaecology of Chittagong Medical College Hospital (CMCH) from January 2011 to December 2011.It was a comparative clinical trial. Study subjects were selected who had eclampsia regarding age, parity, gravidity and gestational age or after recent delivery. Then subjects were categorized into two in alternating method, i.e if first patient was in Group A then next patient was in Group B. Patients who had already received MgSO4 from outside,convulsion due to other causes and having contraindication of MgSO4 therapy were excluded from this study. With written informed consent, Group A received loading dose of inj. MgSO4 and Group B was treated with loading dose plus maintenance dose (standard regimen). The primary outcome was to measure the number of recurrent seizures among the both groups. Secondary outcomes were the side effects, toxicity, Intensive Care Unit (ICU) support, regain of consciousness, normalization of blood pressure and protenuria. The test statistics used to analyze the data were Chi Square test (x2) and unpaired student's t-test. P values of < 0.05 were considered statistically significant The rate of recurrent seizure was 13.3% in loading dose vs 6.3% in standard regimen Group A (0<0.05, RR 2.207, 95% CI 1.089-4.470). Side effects of MgSO4 were higher in Group B (71.1% vs 93%, P<0.01). Considering toxicity 3% was found in loading dose vs 3.8% in standard regimen of MgSO4 i.e almost same (P>0.05). Women who received the standard regimen of MgSO4 are less likely to develop recurrent seizures than those who received loading dose only. Toxicities of MgSO4 are almost same and very little in both the regimen.

Peripheral arterial disease affects with loss of limb if untreated. For decades, arterial bypass has been regarded as one of the trustworthy and effective methods for treatment of atherosclerosis in lower limbs. A 65 year old male patient was treated for a worsening short distance intermittent claudication in left calf muscle. Clinical examinations identified occlusion of the superficial femoral artery. Peripheral Angiogram (PAG) revealed popliteal artery had good calibre with distal run off. Left superficial femoral artery to popliteal artery bypass was performed on the patient with autologous reversed great saphenous venous conduit. Post operative course was uneventful. The pulses of the dorsalis pedis and posterir tibial arteries in left leg regained and remain strong. The Ankle Brachial Index (ABI) increased from 0.60 to 1.09. As far as arterial bypass in lower limb is concerned, the efficacy is usually not so desireable because of lack of vascular substitutes, insufficient availability of autologous vessels and also the scarcity of skilled vascular surgeon. Therefore, it becomes our long-lasting desire to find out a safe and endurable graft conduit and also to establish vascular surgery in a city where this type of surgery was absent previously. We have recently succeeded in performing femoro-popliteal bypass surgery in Chittagong Medical College Hospital (CMCH). Probably this was the first successful femoro-popliteal bypass surgery with autologous great saphenous venous conduit for chronic arterial occlusive disease of lower limb in this hospital.

Published: October 2022

Central Nervous System (CNS) tumor comprises about 2-5% of all tumors. Quite a large number of patients with CNS tumor undergo surgical treatment in Bangladesh. Surgical treatment is greatly facilitated by the use of intraoperative diagnosis. The techniques for intraoperative diagnosis of neurosurgical biopsy specimen are frozen section & crush smear cytology. In our study, a total of 64 cases of CNS tumor was evaluated by crush smear. Among them, 54 (84.38%) cases were brain tumor & 10 (15.62%) cases were spinal tumor, with a slight male predominance (M:F = 1.2:1). The mean age of the patients was 31 years. Cerebrum was the commonest site of brain tumor & astrocytoma was the commonest malignant tumor. Among 64 cases, 61 cases were correctly diagnosed by crush cytologic technique. The accuracy of intraoperative cytologic diagnosis was determined in comparison to histologic diagnosis was 95.3%. It is concluded that crush cytologic technique may be considered as a reliable primary diagnostic tool for intraoperative evaluation of CNS tumor.

Published: October 2022

Fibromyalgia Tender Points (FMTPs) and functional health status measured by Health Assessment Questionnaire (HAQ) as well as health related quality of life by short form-36 (SF-36) in Systemic Lupus Erythematosus (SLE) patients have integrated adherent to each other. Comparison of fibromyalgia tender points and health status in many studies revealed remarkable correlation in both chronic rheumatologic diseases. We observed higher HAQ score and significant positive correlation between FMTP and HAQ score and we also found significant negative correlation in almost all domains of SF-36 with FMTP in SLE patients. Therefore, reduced functional status was found in SLE patients with higher FMTP count. To determine influence of the number of fibromyalgia tender points on functional health status as well as health related quality of life in SLE patients. The observational study carried out enrolling 67 female SLE patients and equal number of asymptomatic female subjects in Lupus Clinic of Rheumatology Wing, BSMMU, Dhaka from April 2005 to October 2006.After fulfilling the inclusion criteria with a detailed history and thorough physical examinations, obtained data were recorded in a pro-forma. 18 FMTP sites and 6 control sites were examined. Positive FMTP scores were recorded in a body chart. Culturally adopted and validated Bengali version of HAQ and SF-36 were filled-up to assess the self-reported health status. Both of the SLE patients and control subjects were classified into two subgroups. 0-10 FMTP’ group and > 11 FMTP group. The HAQ score (Mean + SD) of SLE patients and of controls were 0.54 + 0.54 and 0.17 + 0.25 respectively. The difference was statistically significant (p <0.001). The score (Mean + SD) of all domains’ of SF-36 in both the studied groups were also significantly different. In this SLE series significant correlation (R - + 0.390, p 0.001) was observed between HAQ score and FMTP. And significant correlation was also observed almost in all domains of SF-36 with FMTP. Health status in SLE patients was poor in those who have higher number of FMTP count. Health status was more reflective by SF-36 in comparison to HAQ.
