Published: December 2023

Two-phase flow is the most straightforward flow of multi-phase flow. The void fraction is one of the significant parameters affecting the two-phase flow pattern on both small and mini channels. The flow pattern will be significantly sure, and fluctuations in pressure will change. If the pressure fluctuations are very high, it will affect the piping network system or channel and cause damage. Somebody can find the application of this case of damage to mini heat exchangers, mini boilers, and other small and mini equipment. This paper presents a significant correlation between void fractions and flow patterns. This study used a glass pipe with a length of 160 mm and a diameter of 1.6 mm with a horizontal position. The working fluids used are an emulsion of water and coconut oil with a concentration of 350 mg/dl and 500 mg/dl. The superficial velocity is gas (JG) = 0.08 m/s to 74.6 m/s, and the superficial velocity of the Liquid (JL)= 0.04 m/s to 4.15 m/s. Data measurements use a high-speed camera and are processed using MATLAB R2014a software. The research results showed that the difference in the concentration of the emulsion of water and coconut oil sufficiently affected the value of the void fraction significantly. The void fraction is because the increased concentration of such emulsions affects the increase in the viscosity value of the Liquid. The increase in the viscosity of the Liquid affects the speed of the Liquid tends to decrease. Under these conditions, the increasing superficial velocity of the gas affects the value of the growing void fraction.

Published: December 2023

This paper presents the physical and morphological properties of bamboo fibre derived from Schizostachyum brachycladum. The bamboo fibre was prepared through chemical treatment by sodium hydroxide (NaOH) and went through thermal treatment at 500ᴼC. The changes and modifications of the surface of the fibre were evaluated by scanning electron microscopy (SEM). The surface of the fibre was rough and uneven at samples BF-0 and BF-1. This contributes to their amorphous portions. Sample BF-2, BF-3 and BF-4 showed smooth surface texture and firmness. This proved the fibre was in the transition to a crystalline state. The changes in internal structure changes during the process were successfully determined by Fourier to transform infrared spectroscopy (FTIR). Samples BF- 3 and BF-4 were a sample that underwent a high concentration of NaOH and was fired at 500ᴼC during the fired process. The spectra show the high broad peak at 1436.95 cm-1 and 1435.59 cm-1 where the absorption of C-H bending took place. This proved the increase in the fibre content and a broken layer of hemicellulose and impurities components. The pattern performed by using x-ray diffraction (XRD) showed naturally bamboo properties at an amorphous state. The property behaviour could change by applying the alkali and thermal treatment.

Passive engine mounts have been widely used as the simplest solution to isolate the vibration, noise, and harshness from the engine and chassis for a smooth ride. It is mainly made from rubber and metal, requiring rubber-to-metal bonding. Most studies of rubber-to-metal via adhesive bond report the adhesion properties with the help of a primer. In this study, an adhesive system of graphene nanoplatelets (GNPs) reinforced epoxy resin was investigated for their potential to bond the natural rubber composites (NR) with aluminium alloy (AL-alloy) without any application of primer to assess the GNPs' unique contribution to the adhesion criteria. Chemically treated GNPs were mixed into an epoxy system via an ultrasonication method at 0, 0.5, 3.0, and 7.0 wt% loading variation. The epoxy/GNPs (E-GNP) adhesives were then applied to bond pre-etched Al-alloy sheets with NR composites through the vulcanization bonded. The vulcanization was taken placed in a hot press machine under the temperature of 140°C, a pressure of 100 kg/cm2 for 10 minutes before the samples were subjected to the peel test following ASTM D429. The bonding characteristics were further supported by morphological, compositional, thermal, and structural analyses via Scanning Electron Microscopy, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry, and X-Ray Diffraction. From the results, the E-GNP adhesive system has proven to increase the maximum peel strength of the NR composites-Al alloy by up to 170 % if compared to the control epoxy system. The findings would be a promising technology for improving bonding strength between rubber-metal in diverse applications.

Ferrofluid demonstrates Newtonian or non-Newtonian fluid behaviour depending on the characteristics of ferrofluid. Generally, ferrofluid consists of a stable colloidal suspension of single-domain magnetic particles in a base fluid that can assume non-Newtonian fluid behaviour involving a spin vector and microinertia tensor in flow motion. These two properties possess the theory of micropolar fluid which exhibits microrotational motions and spin inertia in microscopic behaviour. Therefore, this theoretical study is focused to investigate the boundary layer of micropolar ferrofluid flow and heat transfer at the stagnation point on the horizontal flat plate. Magnetite (Fe3O4) nanoparticles and water (H2O) compose in ferrofluid exposed to the magnetic field and thermal radiation is considered. The influences of ferroparticles volume fraction and micropolar parameter on the ferrofluid flow and heat transfer are evaluated mathematically. The partial differential equations have been formulated based on purposed assumptions using Tiwari and Das model and are simplified into ordinary differential equations, which are then solved numerically by Runge-Kutta Fehlberg (RFK45) method. The numerical results of the velocity profile, temperature profile, angular velocity profile, reduced skin friction and reduced Nusselt number are scrutinised in different values of ferroparticles volume fraction and micropolar parameter to estimate the ferrofluid flow and heat transfer. It is found the velocity profile of micropolar ferrofluid flow increases when elevates the ferroparticles volume fraction but decreases when increasing the micropolar parameter. Meanwhile, enlarging ferroparticles volume fraction of micropolar ferrofluid also enhances the temperature profile, reduced skin friction and reduced Nusselt number in the presence of magnetic field and thermal radiation parameter.

Published: December 2023

Human life cannot be separated from water; therefore, water must be fulfilled because it is a basic human need. In the dry season, several regions in Indonesia experience a clean water crisis. This crisis needs to be overcome with methods or equipment that can produce water. Various methods for obtaining clean water were carried out in previous research, but not all methods were suitable for the current condition of Indonesia's territory. One method that could be used in all positions and situations and was suitable for household scales was an air-water harvester machine using a cooling machine. However, this method resulted in less freshwater production. Therefore, the authors were interested to examine the effect of the evaporator positions on the freshwater production and heat transfer rates. This research was carried out experimentally with the working fluid refrigerant R134a. The compressor used was a rotary type 1 PK compressor. This study varied the positions of the coil evaporator, namely the vertical position, the 45° position, and the horizontal position. The highest freshwater production and heat transfer rate were attained using the vertical position. The maximum freshwater production and heat transfer rate were 0.641 kg and 127.17 W respectively.

Published: December 2023

Understanding mixed convection in engineering applications such as heat exchangers, electronics cooling devices, and solar energy collectors have urged researchers to investigate this phenomenon deeper. This study investigates the fluid flow and heat transfer pattern in a two-dimensional (2D) rectangular cavity with sinusoidal heating on the moving top lid numerically. The bottom wall is kept cool while the vertical walls are insulated. The effect of Hartmann number, Ha on the thermal characteristics and fluid flow are analyzed for Richardson number, Ri=1 which indicate mixed convection dominated regime. The governing equations are solved numerically using a SIMPLE algorithm with the finite volume method. The numerical results are displayed in streamlines and isotherms plots. The value of the Nusselt number indicating the heat transfer rate is also discussed. It is found that Ha has a significant effect on the heat transfer process and fluid flow. It can be seen clearly when the value of Ha=30, the rate of heat transfer dropped significantly on the cold wall. Generally, the heat transfer rate decreases with the increase of Ha.

Published: December 2023

Maternal beslenme, fetal büyüme ve gelişmede önemli bir rol oynar. Gebelik sırasındaki olumsuz beslenme koşullarının, bebekteki belirli organların yapısını ve işlevini kalıcı olarak değiştirebilmekte ve bunun da fetal programlanma aracılığıyla birçok yetişkin hastalığına yol açabileceği uzun zamandır bilinmektedir. Bağırsak mikrobiyotasının fetal programlanma hipotezine dahil edilmesi, maternal beslenmenin bebeğin sağlığı ve hastalığı üzerindeki etkisinin daha iyi anlaşılmasını sağlayacaktır. Gebelik ve emziklilik dönemindeki maternal beslenme, annenin mikrobiyotasını etkilemekte, böylece gebelik ve erken yaşam sırasında bebeğe aktarılabilen bakteri havuzunu değiştirmektedir. Mikrobiyotanın bileşimi ve aktivitesinin değişmesi ise hem anne hem de bebeğin sağlığında önemli bir yere sahiptir. Diyetin kompozisyonu ve total enerji alımı ile bebeğin gelecekteki sağlığı ve hastalığının etkilendiğine dair kanıtlar oluşmaya başlamakla birlikte, sadece diyetin kompozisyonunun değil aynı zamanda diyetin zamanının (krononütrisyon) da önemli olduğu belirtilmektedir. Literatürde gece ağırlıklı beslenen annelerin diyet kalitesinin düşük, diyetin glisemik yükünün ve yağ içeriğinin yüksek, meyve-posa tüketiminin düşük olduğu bildirilmiştir ve bunun sonucunda hem anne hem de bebeğin sağlığını etkileyebileceği düşünülmektedir. Bu derlemenin amacı; maternal beslenme, mikrobiyota ve krononütrisyon arasındaki ilişkileri incelemektir.
HOUSING TYPES, POPULATION ATTRIBUTES AND THE DEVELOPMENT PATH OF HOUSING IN LARGE CITIES – A CASE STUDY OF ZHENGZHOU, CHINA
Authors: Shen Zhifeng , Li Jing , Siraj Ahsan , Taneja Shilpa , Li Zhihui
Published: December 2023

Large-city housing costs are commonly attributed to excessive investment or financialization of the property market. The primary cause of housing issues is the imbalance between housing supply and demand. In the context of the urban housing market, the dynamic matching of housing supply and population type plays a crucial role in promoting equilibrium, maximizing the effectiveness of the market’s long-term mechanism, and preserving the coordination and stability of the market. To illustrate this point, the paper analyzes the impact of different attributes of population on housing demand from the perspective of dynamic matching between population attributes and housing types. Taking Zhengzhou City in Henan Province as an example, we consider the relationship between population attributes and housing types in the past, construct a theoretical model of population and housing type and anticipate the future supply scale of various housing kinds. Ultimately, our findings provide a theoretical justification for curbing excessive financialization and housing bubbles in large cities. Furthermore, we propose a practical method for urban housing to return to the essence of life from the perspective of matching housing supply and demand.
EpilepIndex: A novel feature engineering tool to detect epilepsy using EEG signals
Authors: Arunkumar N , Nagaraj B , Ruth Keziah M
Published: December 2023

Epilepsy is a common neurological disease characterized by seizures. A person with a seizure onset can lose consciousness which in turn can lead to fatal accidents. Electroencephalogram (EEG) is a recording of the electrical signals from the brain which is used to analyse the epileptic seizures. Physical visual examination of the EEG by trained neurologists is subjective and highly difficult due to the non-linear complex nature of the EEG. This opens a window for automatic detection of epileptic seizures using machine learning methods. In this work, we have used a standard database that consists of five different sets of EEG data including the epileptic EEG. Using this data, we have devised a novel 22 possible clinically significant cases with the combination of binary and multi class type of classification problem to automatically classify epileptic EEG. As the EEG is non-linear, we have devised 11 statistically significant non-linear entropy features to extract from this database. These features are fed to 10 different classifiers of various types for each of the 22 clinically significant cases and their classification accuracy is reported for 10-fold cross validation. Random Forest and Optimized Forest classifiers reported accuracies above 90% for all 22 cases considered in this study. Such vast possible clinically significant 22 cases from the combination of the data from the database considered has not been in the literature with the best of the knowledge of the authors. Comparing with the literature, several studies have presented one or few combinations of these 22 cases in this work. In comparison to similar works, the accuracies obtained by the classifiers were highly competitive. In addition, a novel integrated epilepsy detection index named EpilepIndex (IED) is able to differentiate between epileptic EEG and a normal EEG with 100% accuracy.
Histoires de vecteurs et de produit scalaire

Published: December 2023

La notion de vecteur est souvent difficile à concevoir pour les élèves et délicate à aborder pour les professeurs en classe. Les vecteurs sont présents dans les programmes de mathématiques et de sciences dès la seconde en lycée général et technologique ou professionnel. Le concept de vecteur résulte des histoires croisées de la physique et des mathématiques, mais enseigne-t-on le même vecteur en sciences physiques et en mathématiques aux lycées ? Un regard croisé sur les pratiques et les conceptions entre les lycées général et professionnel est pertinent. Comme souvent, un regard sur l’histoire éclaire et donne du sens à cet enseignement, et contribue à répondre aux questions : d’où viennent les vecteurs et le produit scalaire, pourquoi les a-t-on inventés ?

Management of acute pulmonary embolism following chest trauma in a resource limited setting – A case report
Authors: Wanigasekara Vinodini , Nanayakkara Sunali Devika
Published: December 2023

Introduction: Pulmonary embolism is a known complication among trauma patients and contribute to significant mortality and morbidity. In the setting of trauma, the signs and symptoms of VTE may be masked. Therefore, a high index of suspicion and timely intervention can improve outcome.

Presentation of case: A 57-year-old healthy female presented with a history of fall from a train, into a gap between the train and the platform. She had sustained cerebral contusions in the frontal lobes and right sided lung contusion. She was resuscitated and managed in the trauma ICU and send to a ward.

She desaturated in the ward and followed by a cardiac arrest. Bed side 2D echocardiogram and CT pulmonary angiogram were suggestive of PE. Thrombolysis was followed by clot retrieval. Patient was discharged home on day 13 after cardiac arrest on warfarin therapy.

Discussion: Causes for PE are multi-factorial. Failure to initiate prophylaxis therapy for deep vein thrombosis in trauma victims is a major cause for PE. Management of PE in a haemodynamically unstable patient with a background history of trauma is challenging. Neuro-imaging revealed bi frontal cerebral contusions hence, the treatment of choice was clot retrieval. However, due to limited resources and logistics, medical thrombolysis was initiated with the involvement of a multidisciplinary team. Clot retrieval was initiated within 14 hours of diagnosis.

Conclusion: Clinical suspicion and early diagnosis of PE can improve outcomes. Management is challenging in a low & middle income countries, where resources are limited. In the presence of contraindications and failed thrombolysis, clot retrieval remains an important aspect in the management of PE.

Venous thromboembolism is a known complication following fractures and surgery. The incidence in orthopaedic surgeries is higher than in other specialities. Proper post procedural anticoagulation will help prevent most thromboembolic events. Several guidelines have been published directing the use of anticoagulation, most optimal agent to use and duration. The decision to anticoagulated must be based on a case-by-case basis considering patient factors as well. The following review article attempts to address these issues regarding anticoagulation in orthopaedic practice.

A case control study was conducted among elderly patients presenting to NHSL accident service. A hundred patients aged more than 60 years who presented with newly diagnosed neck of femur, distal radial and vertebral body wedge fractures following minor trauma were recruited from April 2021 to July 2021. Patients who had previous osteoporotic fractures and previous hip, distal radius and spine surgery were excluded from the study. An additional group of 100 patients who were matched for age and sex presenting to the same unit following minor trauma without osteoporotic fractures were selected as the control group with the same exclusion criteria. Use of statins for more than 4 months and other sociodemographic and lifestyle factors were compared among the two groups.

As no other independent variable was found to be significantly related to osteoporotic fracturs between the two groups, univariable analysis was done. The odds of current statin use in cases with osteoporotic fracture (45.2%) were lower than the odds of current statin use (54.8%) in subjects without osteoporotic fractures adjusted OR 0.74, 95% CI 0.42, 1.32) (p=0.304).

According to our results there might be a protective effect in statin use against osteoporotic fractures although a statistical significance was not demonstrated. However further studies using larger sample size and randomized control studies are suggested to ascertain a statistically significant result.
