Authors: Ashwindran S.N. , Azizuddin A.A. , Oumer A.N. , Abd Razak Azli
Published: September 2022

Climate in Malaysia is heavily influenced by monsoon seasons, where the wind speed pattern is inconsistent and highly unsteady. Existing commercial wind turbines are only designed to accommodate high wind speed regions. In order to harvest energy in Malaysia, design modification is required on conventional wind turbine blade. This paper presents an introductory computational investigation of proposed drag driven vertical axis wind turbine. The objective of this research is to investigate the factors that governs the aerodynamics attributes of the proposed design. The design is simulated in 2D using sliding mesh technique via FLUENT based on URANS model. Previous mesh dependency study shows that fine and medium grid topology indicated a good agreement. In this numerical study, the proposed wind turbine is simulated based on SST k-ω turbulent transport model under fine grid spatial discretization. The design is analyzed under the influence of constant freestream velocity of 25 m/s in order to study the behavior of the turbine at high speed and low RPM. Result shows that high static pressure of 64.8 kPa exerts on the returning blade 1 which overwhelms the motion of advancing blade. Blade 1-3 indicated stable numerical values after 216°. Hence, the governing factors in terms of flow properties that affected the wind turbine is studied for future improvement. It is found that the cavity vane of the proposed design requires modification in order to improve moment.

Dihydroxystearic acid (DHSA) is a product derived from a chemical modification of palm oleic acid. Application of these valuable fatty acids can be found in cosmetics, as a thickening agent and as a coating agent for pigments due to its unique structure. This study investigates the effect of a catalyst on epoxidation and the formation of DHSA by peracid mechanism. The epoxidation yield calculated by relative conversion to oxirane (RCO%) with a high yield of 95% achieved. Thereafter, the epoxidized oleic acid was hydrolyzed to produce DHSA. The formation of DHSA was verified by analysed the physicochemical properties using Fourier Transform Infra-red (FTIR). The kinetic model was being conducted to determine reaction rate using Particle Swarm (PS). The result showed that PS obtained a minimum error of 0.2005 and a correlation coefficient, r of 0.9999.

Published: September 2022

Recently, carbon nanotubes (CNTs) reinforced metal matrix composites (MMCs) have attracted an increasing interest, due to their promising properties such as high Young’s modulus and tensile strength. CNTs are considered to be an attractive reinforcement material for lightweight and high-strength metallic matrix composites. When powder metallurgy (PM) is used to form these MMCs (such as Cu/CNTs composites), the sintering parameters are crucial in obtaining good final parts. This work attempts to investigate the effect of sintering parameters on physical properties in these MMCs. The process comprised of mixing of Cu powder with CNTs, compacting of the powder mixture to form green parts and sintering using a quartz tube furnace under argon atmosphere. In this study, four trials of heating rate were performed and evaluated before sintering process was conducted. Finally, the green body was initially heated isothermally at 100°C for 1 hour with heating rate of 1.0 °C/min and sintered at a temperature of 900°C for 2 hours with heating rate of 0.5 °C/min. The composites contained 0 to 4 vol% of pristine CNTs (PCNTs) and acid treatment CNTs (ACNTs), respectively. It was observed that as the CNTs content increased, the density of the composites was also decreased owing to low density of the CNTs. The sintered part in this present work has undergone volume shrinkage ranging from 12.41% to 17.02% and 13.36% to 19.30%, for Cu/PCNTs and Cu/ACNTs respectively. It was found that the heating rate played an important role in producing a good sintered part. A high heating rate induced large thermal stress and possibly increased the pore volume, leading to swelling. As part of the temperature sensitivity, the heating rate was useful in controlling microstructure evolution in sintering. A correlation between the volume shrinkage, density and porosity of the good sintered part was confirmed in this work.
Pamięć w schizofrenii

Published: September 2022

Przez ponad 100 lat koncepcje zaburzeń pamięci towarzyszyły rozwojowi badań nad schizofrenią. Postępy w badaniach anatomicznych i fizjologicznych, a w szczególności badania neuroobrazowe, przyniosły nowe informacje na temat podłoża i możliwej roli tych zaburzeń.Koncepcje te koncentrowały się w szczególności na modelu pamięci operacyjnej oraz na roli funkcjonowania przedczołowego u pacjentów. Zakłada się, że defekt pamięci operacyjnej – zdolność kierowania zachowaniem multilateralnie, przy stałym filtrowaniu zewnętrznych i wewnętrznych bodźców oraz wypracowywaniu strategii działania – może być podstawowym upośledzeniem prowadzącym do schizofrenicznego zaburzenia myślenia.
Czy depresja może istnieć bez bólu?

Published: September 2022

Związki bólu i depresji mogą być dwukierunkowe: stanom depresyjnym towarzyszy nasilone przeżywanie bólu, a zespołom bólowym – objawy depresyjne. Możemy mówić co najmniej o współwystępowaniu tych dwóch zjawisk, a najprawdopodobniej również o wspólnej etiopatogenezie i terapii.

Definicja zespołu depresyjnego, proponowana przez podstawowe systemy diagnostyczne(ICD-10, DSM-5), nie uwzględnia symptomów często spotykanych w przypadku obniżonego nastroju, w tym dolegliwości bólowych, ale także lęku czy zaburzeń seksualnych. Jest to tłumaczone dążeniem do większej specyficzności rozpoznawania depresji, jednak paradoksalnie może właśnie utrudniać postawienie właściwej diagnozy. Depresja w szczególności może przebiegać wyłącznie w postaci „bólowej maski”, bez ujawnieniasię objawów typowych dla zespołu depresyjnego. Podobnie do utrudnień w praktyce klinicznej może dojść, gdy właściwie rozpoznana choroba somatyczna zostanie uznana za lekooporną z powodu ukrytej depresji, manifestującej się uporczywą ekspresją bólową. Przewlekły stres i przewlekłe choroby somatyczne przyczyniają się do rozwoju przewlekłych zaburzeń depresyjnych i przewlekłych zaburzeń bólowych. Niska samoocena, poczucie niepełnosprawności – poprzez system biochemicznych i biofizjologicznych sprzężeń zwrotnych – prowadzą do nasilenia symptomów somatycznych, w tym także bólu, a to z kolei pogłębia jeszcze bardziej niską samoocenę i obniża nastrój.

Terapia w tego typu stanach musi być kompleksowa, uwzględniająca właściwą farmakoterapię, poradnictwo psychologiczne, techniki relaksacyjne czy medytacyjne, redukcję stresu, właściwie zaprogramowaną aktywność fizyczną, treningi asertywności i inne strategie. Leki przeciwdepresyjne zasadniczo, a w szczególności niektóre ich grupy czy konkretni przedstawiciele – w tym zwłaszcza SNRI (wenlafaksyna, duloksetyna) – redukują znacząco dolegliwości bólowe. Co więcej, potencjał przeciwbólowy tych leków jest na tyle wysoki, że znajdują zastosowanie w terapii stanów bólowych chorób somatycznych, którym niekoniecznie towarzyszą objawy depresyjne.

Published: September 2022

Biomechanical adjustments of the jump shot in presence of an opponent and their associations with shooting efficiency remain to be determined in elite basketball. The aim of this research was to examine the selected biomechanical determinants of the jump shot when shooting over opponents of different height. Nineteen elite basketball players, age 22 ± 3 years, performed three trials of 20 basketball shots in a crossover, randomised manner: over an obstacle of the height of standing reach (RH), over reach height with additional 20 cm (RH+20 cm), over reach height with additional 40 cm (RH+40 cm), and the maximum height jump shot without an obstacle (JSmax). Jump height, the ball entry angle, and shooting efficiency were measured on each trial. Jump height when shooting over RH+40 cm was significantly higher than RH+20 cm (+0.022 m, p = 0.030) and RH (+0.023 m, p = 0.029). Similarly, the ball entry angle was greater at RH+40 cm compared to RH (+7.19 °, p < 0.001) and RH+20 cm (+2.90°, p < 0.001). In contrast, shooting efficiency decreased significantly when shooting over RH+40 cm compared to RH (-10.79%, p = 0.048) and RH+20 cm (-8.95%, p = 0.015). We recorded the highest jump height (0.35 ± 0.08m, p < 0.001) and the lowest angle of entry (39.16 ± 1.19°, p < 0.001) when participants performed JSmax. Shooting over higher opponents should be prioritised in training to significantly improve shooting efficiency. Future research is needed to determine additional potential biomechanical determinants of a successful jump shot in elite basketball.

Published: September 2022

This study aimed to analyze the effect of aquatic plyometric training (APT) on jump performance in volleyball players. Twelve female athletes (16.6 ± 0.9 years) were assessed through the following jump tests: spike height (SH), squat jump (SJ), countermovement jump (CMJ) and CMJ with an arm swing (CMJA). Jump height in each test and the eccentric utilization ratio (EUR) were the outcome measures. APT consisted of sets of drop jumps for 6 weeks (2 sessions/week) at a water depth of 0.75 m. Tests were performed at the beginning of a five-week pre-season period, before and after APT, and four weeks later for the follow-up. Repeated measures ANOVAs were used to analyze data and Hedges’ g to estimate effect size (ES). Performance of all jumps did not change from baseline to Pre-APT. Performance improved in SH (p < 0.001, ES: 1.09), the SJ (p = 0.045, ES: 0.76) and the CMJA (p < 0.001, ES: 0.78) after APT when compared to Pre-APT. No changes were observed after the follow-up period. In conclusion, including six weeks of APT in the training routine of youth volleyball players improved performance of a sport-specific task (SH), the SJ and CMJA, with gains preserved after a four-week follow-up.

Published: September 2022

The purpose of this study was to examine the distribution of physical activities relative to the most demanding scenarios across playing positions during official basketball match-play. Twelve professional basketball players were monitored during twelve matches using a local positioning system. Peak physical demands were measured via total distance covered, distance covered >18 km·h-1, and the number of accelerations and decelerations >3 m·s-2 captured over 30- and 60-s rolling averages. The results showed that players were exposed to more than one high-demanding scenario in all variables and time epochs examined. Additionally, total distance covered presented the greatest number of moderate-demanding scenarios (40-80% of most demanding scenarios), whereas distance covered >18 km·h-1, and accelerations and decelerations >3 m·s-2 presented the greatest proportion of low-demanding scenarios (<40% of most demanding scenarios). Regarding positional differences, backcourt players generally experienced a higher number of scenarios than frontcourt players in most variables, especially in total distance covered. For this variable, scenarios between 20 and 70% of most demanding scenarios during the 30-s epoch (p < 0.001; ES = 0.420.78), and scenarios between 50 and 90% of most demanding scenarios during the 60-s epoch (p < 0.001; ES = 0.400.64) showed significant differences between backcourt and frontcourt players. Our data suggest that match physical activities are position-dependent and variable-dependent. In addition, peak physical demands appear to be repeated during basketball competition. These results may be considered by practitioners to complement average values and most demanding scenarios when prescribing individualized training programs to optimize team performance.
Better Offensive Strategy in Basketball: A Two-Point or a Three-Point Shot?
Authors: Gou Huancheng , Zhang Hui
Published: September 2022

To better understand and explore the development trend of the offensive strategies of the world’s top basketball leagues, this study took NBA shooting data in the regular seasons from 2009/2010 to 2018/2019 as the samples and analysed the relationships between the shooting score ratio and game win probability, and the practical application of offensive strategies in games. The results showed that (1) increasing the number and the percentage of three-point offenses in the game can improve the probability of winning. However, too many two-point shots can affect the team’s winning probability to a certain extent. (2) The strong teams in the NBA focused more on the outside offense, while the weak teams focused more on the inside offense. (3) Statistical data further showed that whether a team’s opponent is strong or weak, taking the offensive strategy that tends toward the outside shot can lead to a higher game win probability than the offensive strategy that tends toward the inside offense.
Effects of Leg Stiffness Regulated by Different Landing Styles on Vertical Drop Jump Performance
Authors: You Chieh-Hsin , Huang Chi-Huang
Published: September 2022

The purpose of this study was to investigate the effects of stiffness regulated by landing styles on drop jump performance. Twenty-four male lacrosse athletes performed drop jumps with stiff (ST), self-selected (SS), and soft (SF) landing from a 0.42 m box. Leg stiffness, ground contact time, depth, jump height, maximum ground reaction force (GRF), GRF at the start of the propulsive phase, mean power, peak power, and the reactive strength index (RSI) were calculated. The results showed that jump height and the RSI had strong correlations to power production in all drop jump styles. Power would be a key factor to overall athletic performance. Repeated measures ANOVA showed significant differences (p < 0.05) in all variables among the three styles. Drop jumps with SS landing had comparable jump height to drop jumps with SF landing and power output to drop jumps with ST landing. Drop jumps with ST landing had significantly lower jump height, but higher GRF, power, and the RSI compared to drop jumps with SF landing. In drop jump testing, drop jumps with SS landing should be used if power and jump height were the major concerns; if the RSI was the major concern, drop jumps with ST landing should be used. Training with drop jumps, one of the main objectives should be increasing power output due to its significant correlation to jump height and the RSI in all conditions.

Published: September 2022

The objective of this study was to compare peak surface electromyography (sEMG) activity of selected muscles along with inter-limb asymmetries between a control (CONT) and a Sling shot assisted (SS) bench press exercise. Ten resistance-trained males with at least three-year experience in resistance training (22.2 ± 1.9 years, 88.7 ± 11.2 kg, 179.5 ± 4.1 cm, bench press one-repetition maximum (1RM) = 127.3 ± 25.9 kg) performed the flat bench press exercise under two conditions at selected loads (85% and 100% of 1RM assessed without the SS). Peak sEMG amplitude of triceps brachii, pectoralis major, and anterior deltoid was recorded for the dominant and the non-dominant side of the body during each attempt. The comparison between the dominant and the non-dominant side was carried out using the limb symmetry index (LSI(%) = (2*(XR - XL)/(XR + XL))*100%) where XR = values of the right side and XL = values of the left side. There was a main effect of condition (p = 0.004; η2 = 0.64) and the load (p = 0.004; η2 = 0.63) for the triceps brachii LSI in parallel with a main effect of condition (p = 0.003; η2 = 0.42) for the anterior deltoid LSI. Post hoc analysis for the main effect of condition showed significant differences in the LSI between the CONT and SS conditions for the triceps brachii (p = 0.003; 1.10% vs. -8.78%) as well as for the anterior deltoid muscles (p = 0.03; 12.91% vs. 9.23%). The results indicate that the assistance of the Sling shot significantly affects the sEMG activity pattern on both the dominant and non-dominant sides of the body while influencing inter-limb asymmetries.

Authors: Marinier Michael C. , Ogunsola Ayobami S. , Elkins Jacob M.
Published: September 2022

Background

Bioimpedance analysis (BIA) is a readily available tool to assess body composition in a clinical setting. BIA has received little attention in orthopaedics and namely joint arthroplasty. This study aims to quantify changes in body composition in the immediate peri-operative period following total joint arthroplasty.

Methods

Adults scheduled for elective total joint arthroplasty were recruited to participate. Patients underwent BIA scans in the immediate peri-operative period: pre-operative on their day of surgery, post-operative day 0, and post-operative day 1.

Results

67 patients were enrolled to undergo BIA scans. Mean age was 62.64 ± 10.28 years old, and 49.2% were females. The all-supine cohort exhibited a 0.36 ± 0.61 kg increase in dry lean mass (p < 0.001) and 1.30 ± 2.14 kg increase in lean body mass on postoperative day 0 (p < 0.001). Patients received to 1.16 ± 0.58 kg of fluid mass, on average.

Conclusion

BIA is a rapid, portable tool that allows for body composition analysis of an inpatient surgical population. This study demonstrated that BIA can detect net fluid changes and may approximate implant mass following total joint arthroplasty. This may aid surgeons in interpreting post-operative body composition changes.

Authors: Pestrea Cătălin , Cicală Ecaterina , Gherghina Alexandra , Orțan Florin
Published: September 2022

His bundle and left bundle branch pacing are regarded as physiological options for permanent ventricular pacing because they use the fast-conducting specialized tissue for depolarization. The development, more than a decade ago, of a dedicated delivery kit using a lumenless lead, revolutionized the procedures and dramatically increased the success rate. After these consistent results, the industry is focusing now on releasing more tools for conduction system pacing.

We present two cases of conduction system pacing using a new delivery system based on stylet-driven leads and share our first impressions on the advantages and disadvantages compared to the lumenless technique.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause cytokine storm characterized by the excessive release of pro-inflammatory cytokines, leading to lymphopenia and neutrophilia. Lymphopenia and high Neutrophil-Lymphocyte Ratio (NLR) on admission were associated with the severity of the disease. Objectives: To found out lymphopenia and high NLR in SARS-CoV-2 infection. Methods: This was a cross-sectional descriptive study on all patients infected with SARS-CoV-2 who met the inclusion and exclusion criteria at Dr. M. Djamil Hospital Padang from March until August 2020. Lymphocyte count and neutrophil count on admission were examined by flowcytometry method and NLR was calculated. Lymphopenia is a lymphocyte count of <1.5x103/mm3 and high NLR is ≥ 3.13.  Results: The study samples were 123 patients, with 58.5% women. The mean age was 47.80 (15.59) years. Lymphopenia was present in 39% of patients with mean lymphocyte count was 1.84 (0.83) x103/mm3. High NLR was present in 48% of patients with a mean NLR was 5.06 (4.87). Conclusion: Lymphopenia was present in 39% of patients infected with SARS-CoV-2 and high NLR was present in 48% of patients infected with SARS-CoV-2.Keywords:  lymphopenia, neutrophil-lymphocyte ratio, SARS-CoV-2

SARS-CoV-2 infection is a systemic infection that significantly affects hematopoiesis and the patient's immune response. Drastic increase in the production of proinflammatory cytokines like interleukin-6 (IL-6) play a role in mechanism of lymphopenia in COVID-19. Some indicators of inflammation markers include Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP). Objectives: To determined the correlation between Erythrocyte sedimentation rate (ESR) and C-Reactive Protein (C-RP) levels in patients with covid-19. Methods: This research was an analytic observational study with a cross-sectional approach. The samples in this research were 10 ESR and 10 CRP data in a patient with positive COVID-19 at the Mataram University Hospital. Results: A minimum value of 0.50 was obtained from 10 samples of CRP examination, while the maximum value was 79.90 with an average value of 32.24 and a standard deviation of 30.36. The Erythrocyte sedimentation rate (ESR) examination obtained a minimum value of 6.00 from 10 samples, while the maximum value was 103.00 with an average value of 53.60 and a standard deviation of 36.40. Conclusion: There is no correlation between the value of Erythrocyte sedimentation rate and C-Reactive Protein levels in patients with Covid-19.Keywords: Covid-19,  C-reactive protein, erythrocyte sedimentation rate

Published: September 2022

The anatomical variations of the nasal and sinus paranasal can cause headaches. The most common variants have deviated septum, concha bullosa, and agger nasi cells. These variations can cause narrowing of the osteomeatal complex. Computed tomography was the primary modality for evaluating anatomical variations of the nasal and paranasal sinuses in diagnosis and management. Functional endoscopic sinus surgery was generally performed to restore the sinuses' drainage and ventilation in anatomical variations. It has been reported a 45-year-old woman with a congested left nostril and headache that has gotten worse since 2 months ago and computed tomography of the paranasal sinuses show thickening of the bilateral maxillary sinus mucosa, bilateral anterior ethmoid, left septum deviation, concha bullous, and right inferior turbinate hypertrophy. Functional Endoscopy Sinus Surgery was performed, found anatomical variations namely, deviation septum, concha bullosa, agger nasi cells and supra agger cells. The operation gave satisfactory results. Correct evaluation of anatomical variations based on history, physical examination and investigations can assist in patient management and avoid errors during surgery. The operation gave a satisfactory result for managing symptoms on patient with anatomical variation of nasal and paranasal sinuses when compared with medicamentosa.Keywords: anatomical variations,  agger nasi cells , concha bullosa,  deviated septum, headache, supra agger cell

Editorial- The Resilience Shift
Authors: Chaiechi Taha
Published: September 2022

Economic resilience is operative in three levels of macro (governments), meso (market mechanisms) and micro (individual agents/ businesses) (Chaiechi, 2022). Economic resilience can be achieved through either or both inherent and adaptive strategies. Inherent resilience is an ordinary ability to manage a crisis, and it is routinely provided through resource allocation. Adaptive resilience is generally the system's ability to maintain functionality after being shocked that is achievable on the basis of extra effort. Due to large degrees of interdependencies between economic sectors, adaptive resilience in one sector can be significantly affected by changes in adaptive capacities in another. Therefore, efforts to build economic resilience cannot be implemented only by governments and at the macro level.
Pathways for Urban Food Security in the Pacific
Authors: Watt Lucas , De Waegh Roxane , Watt Greg
Published: September 2022

The urban context is often sidelined in the academic discourse surrounding food security in the Pacific. Yet, for some Pacific nations, cities are the home for most of their citizens. In this thematic literature review, we direct our attention toward the increasingly important topic of food security in Pacific cities. We investigate how the urban informal food sector historically has provided a baseline of food security in Pacific cities. The production, livelihood, and exchange practices that define the urban informal food sector can be traced back to the forms of urbanisation and migration that occurred in the post-independence era in the Pacific. However, we also identify how urban formalisation and globalisation are undermining the key tenets of social relationality that the informal food sector relies upon. As such, the forms of food security provided by the urban informal food sector are being slowly eroded. By identifying these disruptions to the informal urban food sector, we identify pragmatic pathways to develop the basis of a conceptual framework for urban food security in the Pacific. These pathways revolve around invigorating the forms of social relationality within the informal food sector's production, livelihood, and exchange practices.
