Fuel and material cost is increasing day by day in all the industries. In IC engine, engine fails mainly due insufficient of heat transfer from the cylinder wall to the atmospheric air. In SI engine, heat is extracted from the cylinder wall by convection heat transfer through the fins. In this paper optimal hole size on the fins is obtained in order to extract the heat from the engine by numerical method. ANSYS is used to find the temperature distribution on the fins , when there no holes, when there is hole diameter as 2mm, 2.5mm,3 mm, 3.5mm,3.8mm, 4mm and two row holes of 3.5 mm diameter. For this analysis fluid flow (fluent) is chosen, air is circulated on engine with 16.666 m/s velocity and with atmospheric pressure. Temperature value of 800K is applied to the cylinder wall. Temperature is compared with the all hole diameter cases, and it is found that the 3.5 mm diameter hole gives the best results compare to all other hole diameter. The temperature difference 0.04K is obtained between without holes and with 3.5 mm diameter. The 3.5 mm diameter hole fins are used where material cost goes at high rate.

Hydrodynamic shear force along the bottom microchannel wall has been utilized in cell adhesion studies to detach cells in microfluidic channels. Due to the small dimensions of microfluidic channels, the shear stress produced in a conventional microchannel is dependent mainly on the fluid velocity and channel height. The wall shear force magnitude increases as the channel height is reduced. However, a reduced channel height decreases the sample volume to be contained in the fluidic channel and also increases the pressure drop significantly which may fail the fluidic device. In this study, a novel microchannel with a trapezoidal structure was investigated using computational fluid dynamics simulations. The key fluidic properties, including wall shear stress, sample volume, and pressure drop of the trapezoidal microchannel are compared with those of a conventional straight channel with a reduced channel height. We found the trapezoidal structure produces a wall shear stress of 5 Pa in the region of interest similar to that of the straight channel with a small channel height (50 μm) while having less than 30 percent pressure drop. Additionally, the pressure drop can be reduced by modifying the geometry of the trapezoidal channel to minimize pressure loss.

A set of zinc oxide (ZnO)/polyvinyl alcohol (PVA) nanocomposites were prepared by mixing presynthesized zinc oxide nanoparticles and polyvinyl alcohol (PVA) in different weight percentages with solution casting technique.Different characterization methods are carried out to determine the material properties. The effects of ZnO nanoparticles loading level on electrical properties of the nanocomposites were investigated in details. The intermolecular interactions within the polymer nanocomposites were explored by FTIR and XRD. The formation of nanocomposites and changes were investigated by SEM analysis.It showed that ZnO nanoparticles were homogeneously dispersed throughout the whole polymeric matrix. DC conductivity was measured in the temperature range 70-300K and it obeys Arrhenius relation. Activation energies were evaluated from Arrhenius plots for all compositions. The samples show a semiconductor-like behavior in regions I (300-130 K) and II (130-70K).The activation energies are smaller at lower temperature range as compared to higher temperature range. The change in conduction mechanism arises at different temperatures, which are feature of the samples. As the ratio of ZnO to polymer changes these switching positions are shifted to upper temperatures. All the composites obey the Arrhenius equation for the conductivity mechanism which confirms that the nanocomposites are thermally activated. The dc conductivity of all the samples follows a simple hoping type of charge conduction method. This is evident from Fourier Transform Infrared Spectroscopy (FTIR) studies.

Most of the industries are concerned with flow measurement and accurate measurement of fluid is important to obtain specific proportion as per process requirement. Generally Venturimeter (VM) is utilized in enterprises due to notable highlights offered by it. VM works on the principle of pressure difference i.e. Bernoulli’s principle. By varying cross sectional area of flow, it creates pressure difference along its length which is used to calculate theoretical discharge. Head loss in VM is less as compared to other flow measuring apparatus. Because of its specific geometry eddies formation is avoided causing less head loss. The coefficient of discharge (Cd ) is an important parameter always referred in case of flow measuring devices. For VM it varies from 0.95 to 0.99. Tests have been performed in accordance to Taguchi L9 O-A on cast iron pipe to examine the impact of variations of viscosity, and rates of flow on the Cd .

Elderly and people with disabilities often rely on others for their locomotion. With this emerging world of automation and technologically advanced society we live in a smart wheelchair with appropriate automation can be a life changing innovation for them. One might wonder what is the need for a wheelchair to be smart or for that matter why anything needs to be smart. The answer is simple, to overcome the limitations of the existing technology. We aim on integrating a simple Manually operated wheelchair with features like Obstacle Detection with appropriate technologies such as voice control or gesture control for people who are not able to locomote like a normal person can. With this project, not only do we help a person using a normal wheelchair more easily but also make life easier for those who have other disabilities which are standing as an obstacle making it difficult for them to walk. For instance, a blind person can use a smart wheelchair that allows voicecontrolled movement or even gesture-controlled movement. Another might be of a person who can’t speak, will now be able to control everything with his bare hands. Wheelchair coupled with the appropriate sensors that automatically detects the obstacles/objects in the proximity and takes appropriate action consequently and In addition to that it may also be controlled by another person taking care of the disabled by giving commands such as forward, backward, upright etc. This not only reduces the user's efforts but also helps people to take care of their elderly. Voice/gesture control system makes everything simple. Just visualize the application of it in a hospital where the nurse has to manually handle the patient's wheelchair for even the slightest of movement. This system on the other hand needs only text or voice input command, and based upon the predefined command received from the user, the system will execute the task. This project even enforces a GSM module which uses the sim card, which can help in tracking the wheelchair when required, like in case where a user is in difficulty and needs emergency help, a message asking for help can be sent to the intended person.

Temperature that can vary as high or low especially in Industries will cause discomfort to products and organization. So, we use Temperature sensors to monitor and measure the temperature at industries. These sensors are fixed into a component which tends to be problematic due to overheating issues. The sensors use a GSM module which constantly sends the temperature updates of the machine and surroundings to your Personalized Devices. This project not only tells the temperature in the industry and machines but also changes the temperature according to the organization by turning on the humidifiers or Extinguisher around the area. This can also send Emergency signals to the fire department if there is a serious fire. These devices are embedded with GSM module So these can also be used in Transport Systems so it can track the location and monitor the temperature around it at the same time.

Orthogonal frequency division multiplexing (OFDM) schemes are used extensively nowadays in large number of practical systems, but OFDM may not be the ideal solution for 5G scenarios because OFDM has high Out of band emission (OOBE) due to high spectral leakage and high peak to average power ratio (PAPR). Therefore Filtered OFDM (F-OFDM), which uses sub band filtering, is proposed as the most flexible waveform for 5G. However there is no work listed in the literature so far that compares the bit error rate (BER) performance of F-OFDM and conventional OFDM in AWGN, Rayleigh and Rician channel. This paper presents the simulation results on the BER performance of F-OFDM and OFDM in presence of AWGN, Rayleigh and Rician channel. The comparison is also done in terms of OOBE and PAPR factor. Results indicate that F-OFDM shows significantly less spectral leakage with same performance in terms of BER compared to conventional OFDM. However for the cases considered, OFDM performance is slightly better than F-OFDM in terms of PAPR factor.

Data pre-processing is the process of transforming the raw data into useful dataset. Data pre-processing is one of the most important phase of any machine learning model because the quality and efficiency of any machine learning model directly depends upon the data-set, if we skip this step and design a model with data sets containing missing values then the model we have designed will not be that efficient and will be inconsistent model. This paper describes the methodology for pre-processing the data in seven sequence of steps using python powerful libraries which are open source machine learning libraries that support both supervised and unsupervised learning like pandas is a high level data manipulation tool, scikit learn which provides various tools for model fitting, data pre-processing, model selection and many other utilities. These steps include dealing with missing value, categorical values, importing data sets etc. This analysis helps in cleaning and transforming the datasets which future applied to any learning model and produce a efficient machine learning model.

Is hemoglobin the missing link in the pathogenesis of COVID-19?
Authors: Majeed Amer , Shajar Matloob Ashraf
Published: May 2020

This editorial considers studies which establish our current understanding of SARS-CoV-2 and the indicated direction for treatment of COVID-19 patients and future research. Recent modelling studies point to the effect of SARS-CoV-2 on hemoglobin as a key element in understanding the pathogenesis of COVID-19. This would suggest that the focus of treatment of COVID-19 would need to shift towards maintaining the oxygen carrying capacity of blood; potentially with blood transfusions and super-oxygenation, perhaps including hyperbaric oxygen therapy. Further, early prevention of thromboembolism, and suppression of the immune response due to hemoglobin damage, may help contain the clinical course.

Can addition of low level laser therapy to conventional physical therapy be beneficial for management of pain and cervical range of motion in patients with trigger point of upper trapezius?
Authors: Waseem Iqra , Tanveer Fahad , Fatima Arooj
Published: May 2020

Objective: Trigger points commonly develop in upper trapezius muscle. These might be associated with neck pain arising from trigger points of trapezius. This study was conducted to compare the effectiveness of conventional physical therapy (CPT) with and without low level laser therapy (LLLT) on pain and cervical range of motion (ROM) in patients with trigger point of upper trapezius muscle.

Methodology: An RCT was conducted with a sample size of 62 patients. The study was completed within 9 months after approval of synopsis. Data were collected from Health Care Physiotherapy, Sports, Spine & Rehabilitation Center, Faisalabad (Pakistan). Patients were randomly allocated into two equal groups; 31 patients of Group-1 received low-level laser therapy with CPT, while Group-2 (n=31) patients received CPT as the only treatment protocol. Patients pain level was assessed using Numeric Pain Rating Scale (NPRS) and cervical ROM was measured by goniometry at baseline and subsequently at 2nd and 4th week follow-ups.

Results: Results of the study obtained by applying repeated measures ANOVA showed that there was mean reduction in pain scores from day 1 to week 4 in within group analysis of LLLT + CPT Group (Group=1) and within group analysis of CPT Group (Group=2) (p < 0.05). Statistically significant improvement was observed in all mean cervical ROMs especially for lateral flexion ROM for both groups in within group analysis (p < 0.05). Statistically significant improvement was seen in NPRS score at week four between Group-1 and 2, measured by independent sample t-test with p < 0.05. Whereas, independent sample t-test results showed no significant improvement in cervical ROMs at week four between Group-1 and 2 (p ˃ 0.05).

Conclusion: Conventional physical therapy and low level laser therapy used in combination are more effective than conventional physical therapy alone in patients of trigger points of upper trapezius.

Conventionally, these problems have been suggested to be a manifestation of positional vertebrobasilar insufficiency. Angiography tends to be normal in TOS sufferers, however, and doppler ultrasonography of the vertebral artery fails to demonstrate severe flow reduction. TOS is attributed to the brachial plexus and subclavian artery being compressed in the interscalene triangle, costoclavicular or subpectoral passages. The vertebral and carotid arteries arise from subclavian artery proximal to the sites of obstruction in TOS. Numerous reports of resolved CCM post-scalenectomy and first-rib resection, despite lacking vertebral artery impairment, have been documented. TOS CCM, moreover, share many of the symptoms seen in systemic and intracranial hypertension. Reports of subclavian thromboembolus migrating to the head have been documented in incidences of TOS, showing the potential for flow retrogradation. We postulate that the blood prevented from entering the brachium due to distal subclavian compression, retrogrades to the brain via the carotid and vertebral arteries, resulting in craniovascular hyperperfusion and congestion.

О ПРОЕКТЕ ТОЛКОВОГО ДВУЯЗЫЧНОГО СЛОВАРЯ-ТЕЗАУРУСА
Authors: RASULOVA Makhfuza
Published: May 2020

Актуальность исследования заключается в самой постановке проблемы, а также в разработанных автором возможных критериев при составлении словаря-тезауруса нового типа.
Особое внимание уделено изучению истории вопроса, с целью показать динамику развития отечественной и зарубежной прикладной лексикографии.
Результаты анализа позволили сделать вывод о том, что теория и практика лексикографии претерпевают значительные изменения в последние десятилетия. Практика лексикографии активно обогащается новыми типами словарей; все глубже становятся концепции теории лексикогра¬фии.
Однако недостатки двуязычных словарей традиционного типа, их пассив¬ность вынуждают исследователей серьёзно рассмотреть необходимость принципиально иного способа словарной презентации двуязычного материала.
На основе критического анализа научной литературы и трактовок различных теорий, определяется потребность в составлении двуязычных идеографических словарей, цель которых заключается в том, чтобы показать общую картину лексики как системно-структурное образование. При этом принципиально важным для лексикографических источников подобного типа является отражение сло¬варного состава языка в виде семантических группировок, объединяющих в себе лексикон с единой категориально-лексической семантикой.
Итак, разработка концепции нового двуязычного словаря-тезауруса с учетом достижений современной науки, прежде всего, относительно системно-идеографического изучения лексики, — в настоящее время является чрезвычайно актуальной задачей как теоретической, так и прикладной лексикографии.
Оригинальный авторский подход к составлению нового типа двуязычного идеографического словаря-тезауруса, без сомнения, поможет внести ясность в лексикографическую практику и выйти на ту ступень, которая, оказывая непосредственное влияние на речевую практику, обеспечит успешную коммуникацию.
Managing Intraday Liquidity: The Mexican Experience
Authors: Alexandrova-Kabadjova Biliana , Solís-Robleda Francisco
Published: May 2020

El presente estudio calcula el uso proporcional de la liquidez del Sistema Mexicano de Pagos Liquidados en Tiempo Real, SPEI, durante el período de un mes. En particular, nuestro interés es conocer qué tan diferente es el nivel de liquidez en la liquidación en tiempo real de las transacciones de pagos de bajo y alto valor. Para ello, creamos un ambiente artificial, en el cual utilizamos datos históricos de 7 de abril a 7 de mayo de 2010 y reproducimos las condiciones operativas del SPEI. Para cada uno de estos días, organizamos las transacciones en cuatro sets, de acuerdo con su valor: todos los pagos, órdenes de pago con valor superior a 100,000 MXN; transacciones con valor superior a 1,000,000 MXN y pagos con valor superior a 10,000,000 MXN. Medimos el uso de liquidez en escenarios con diferentes requisitos de velocidad de liquidación. Encontramos que entre los participantes las estrategias de liquidación son heterogéneas. En particular, de acuerdo con el tamaño de la orden de pago, semanalmente los participantes siguen diferentes patrones de liquidación. Aún más, los pagos en el mismo conjunto no son tratados homogéneamente por los bancos.
Intercultural Competence in Short-Term Study Abroad
Authors: Nguyen Annie
Published: May 2020

Assessment is growing for short-term study abroad as the majority of students (63.1%) continue to choose this option (Institute of International Education, 2016). This study examines possible gains and factors influencing such gains in students’ overall intercultural competency following participation in a short-term program. Using the Intercultural Effectiveness Scale (IES) survey distributed before, after, and three months following the study abroad experience, data was analyzed for fifty-five students across eight different short-term programs at three distinct institutions within the state of Texas. Document analysis of program syllabi also looked at connections to structured activities and assignments. The results demonstrate the potential for short-term study abroad programs ranging from two to five weeks to have significant impacts on students’ self-perceived intercultural competency that appear most affected by intentional structures. These findings support recommended practices of using well-defined activities and assignments, incorporating opportunities for meaningful local interaction, and providing planned re-entry.

Inversion du domaine de l’adoption : les technologies latentes
Authors: Bidan Marc , Biot-Paquerot Guillaume , Chaboud Mathieu-Claude , Lentz Frank-Mahé
Published: May 2020

Cet article appréhende le domaine de l’adoption des technologies de l’information. Il s’appuie sur le séquençage entre adoption primaire et adoption secondaire (Gallivan, 2001) puis il l’adapte à l’adoption individuelle et organisationnelle. A l’inverse des modèles traditionnels de l’adoption des outils de gestion, les technologies avec effets de réseau, dont l’utilité marginale s’accroit lorsque la base d’utilisateur augmente (messagerie, e-paiement, visioconférence, etc.), l’acceptation initiale par les utilisateurs est liée à la perception d’une masse critique d’usagers potentiels. Ces technologies sont appelées technologies latentes lorsqu’elles sont préinstallées ou aisément déployables. La crise sanitaire actuelle met notamment en lumière des succès rapides et massifs (WhatsApp, Teams, etc.). Elle impose de repenser et d’inverser les modèles d’adoption en proposant une séquence où les technologies latentes sont d’abord adoptées par les utilisateurs avant que l’organisation ne les intègre et valide ex post.
How to succeed in data science projects industrialization ?
Authors: Potelle Hervé , Leblond Laurent
Published: May 2020

Industrializing Data Science projects in business lines results from a transformation that takes place from strategic scoping to operational management. By using a learning base, it is possible to predict with performance the success or the failure of future projects in the pre-scoping phase. Industrializable projects can thus be correctly predicted by weighting the following six criteria: the business question, the business mandate, the business availability, the "Data" competences, the quality / Data quantity and the Data monitoring. On this core, the design of a Predictive Score Card evaluation tool allows an optimized projects pre-scoping.
