In India, weeds compete with primary crop for soil nutrients (NPK), which are currently Worth 5,000 crores every year. Total crop losses due to weeds are estimated to be approximately Rs. 10,000 crores (Rao, 2000). Weed control is a major concern in dry land agriculture, and producers face some of the most severe challenges faced by the industry. Farmers used a variety of weed management methods, such as traditional sickle equipment, animal-powered weeding, and chemical weeding. However, none of these weed control approaches, which deplete onion energy marginally, are successful, and chemical weed control lowers soil quality. To address this issue, mechanical power operated challenge at times are becoming incredibly common, as they are used to minimize human work while maintaining sufficient efficiency.

An easy, specific and precise RP-HPLC technique has been created and tested for the quantification of doravirine in pure and its tablet dosage forms. Doravirine is a novel nonnucleoside reverse transcriptase inhibitor (NNRTI). It is utilized in the treatment of HIV-1 infection in combination with other antiviral medications therapies (ARTs). The separation was completed on the Agilent C18 column (150 x 4.6 mm) with 5µ particle size. 0.01N potassium dihydrogen phosphate and acetonitrile (ACN) (60:40 v/v), at a flow rate of 1ml/min, was used as an optimum mobile phase. The wavelength chosen was 210 nm. The retention time for doravirine was 2.379 min. Linearity of doravirine was found to be 25- 150μg/ml. Linearity equation attained was y= 11776x+ 2813 with correlation coefficient 0.999. The relative standard deviation for precision was found to be less than 2%. % Recovery was found as 100.13% for doravirine. The LOD and LOQ for doravirine were found as 0.06 µg/ml and 0.18 µg/ml.

Published: June 2022

All the aircraft are equipped with an anti-icing system to prevent ice accretion on the body of the aircraft. The anti-icing system is important because ice accretion degrades the performance of the aircraft and may cause aircraft crashes. Piccolo tube Anti-icing system uses the impingement hot air and creates hotspot on nacelle lip-skin and edges of wings. The temperature distribution caused by the impingement of hot air must be studied to get a better design of the anti-icing system. The skin geometry shape affects hot airflow behavior in the impingement vicinity, hence influences temperature distribution on wing skin and nacelle lip-skin. Thus, the CFD simulation of the hot air impingement air various concave curvature radius was conducted by using ANSYS Fluent 19.2. The result shows the temperature contour has been plotted from the software. Correlation between Nusselt number on impingement point and Reynolds number was successfully done as the validation. Increasing the Reynolds number increases the dimensionless temperature of the concave plate. Temperature is 0.147125 has been recorded as the highest dimensionless temperature under the set of an air temperature of 43°C, Reynolds number of 4070, and 300mm curvature radius. Besides that, increases in heat dissipation decrease the dimensionless temperature of the plate with the curvature radius also decreases. The dimensionless temperature increases from 0.138747 to 0.142316 when the curvature radius increases from 150mm to 300mm.
The Consequences of Thermal Radiation and Chemical Reactions on Magneto-hydrodynamics in Two Dimensions over a Stretching Sheet with Jeffrey Fluid
Authors: Vijay K. Patel  , Jigisha U. Pandya
Published: June 2022

In this research paper, the Homotopy Analysis Method is used to investigate the two-dimensional electrical conduction of a magnetohydrodynamic (MHD) Jeffrey Fluid across a stretching sheet under various conditions, such as when electrical current and temperature are both present, and when heat is added to the presence of a chemical reaction or thermal radiation. Applying similarity transformation, the governing partial differential equation is transformed into terms of nonlinear coupled ordinary differential equations. The Homotopy Analysis Method is used to solve a system of ordinary differential equations. The impact of different numerical values on velocity, concentration, and temperature is examined and presented in tables and graphs. The fluid velocity reduces as the retardation time parameter (λ_2) grows, while the fluid velocity inside the boundary layer increases as the Deborah number (β) increases. The velocity profiles decrease when the magnetic parameter M is increased. The results of this study are entirely compatible with those of a viscous fluid. The Homotopy Analysis Method calculations have been carried out on the PARAM Shavak high-performance computing (HPC) machine using the BVPh2.0 Mathematica tool.

Published: June 2022

In some countries, wind turbines are designed to operate at relatively high speeds to be appropriately efficient, limiting the use of wind turbines in urban areas with low wind speeds. Thus, innovation is needed to enhance the possibility of wind energy use within the range of low speeds. In order to increase the electrical power of the wind turbines, the velocity of the wind blowing on the wind turbine, is the most important factor that has to increase. In this paper it has been recommended that contraction nozzles could be applied between Wind Turbines and wind-way to provide the wind through themselves with more velocity. The main objective of this research is to optimize the nozzle design for vertical axis wind turbine (VAWT). Specifically, this study investigates the effect of wind velocity on different shapes of nozzle to develop the suitable nozzle for the wind turbine. For that purpose, the ideologies of contraction nozzle have been studied. Different nozzle design concepts were developed and the wind speed for each design is simulated.

Facial Recognition is the most used technology nowadays. Apart from Bio-metrics, Iris scan, fingerprint recognition methodologies, facial recognition is emerging recognition methodology these days. One of the most effective applications of this methodology is automated attendance using facial recognition, which is contact less, secure, and effective unlike in tradition way (manual attendance) it saves more time. Methodology used in this project involves Viola-Jones algorithm for face detection and Eigenfaces approach for feature selection and classification. In Viola-jones algorithm inputs are taken as captured images of individual persons and produce a dataset containing cropped images of individual and these dataset is directed to Eigenfaces approach as input and training of data occurs through the process of calculating eigen vectors for each eigenface. At the time of testing, Euclidean distance between eigen vectors of testing image and eigen vectors of trained eigen faces determines the matched individual. Facial recognition can also be done with PCA, which has 79.6 percent accuracy, and LBPH, which has 90.23 percent accuracy. However, when employing the Eigenfaces technique, the accuracy is 93.07 percent. MATLAB software with Computer Vision Toolbox and Deep Learning Toolbox is used for this work.

BACKGROUND: The global coronavirus disease-2019 pandemic has forced nursing schools in Indonesia to implement online learning. The association between online learning variables and psychological distress among nursing students is not fully understood.

AIM: This study aimed to assess psychological distress among nursing students and the association between online learning variables and psychological distress.

MATERIALS AND METHODS: A cross-sectional study was conducted from November 2020 to February 2021. Six hundred and thirty-five nursing students from four universities in Indonesia participated in this study and were recruited through a consecutive sampling method. The measurement of psychological distress used the 10-item Kessler Psychological Distress Scale. Ordinal logistic regression was used to analyze the association between online learning predictors and psychological distress.

RESULTS: Most of the respondents had severe psychological distress (n = 194; 30.6%). Older age was found to act as a protective factor against psychological distress (adjusted odds ratio [aOR] = –0.159, p = 0.035; 95% confidence interval [CI]: (–0.307)–(–0.011)). Contrarily, not living at their own home during lockdown (aOR = 1.019, p = 0.001; 95% CI: 0.657–1.382), always feeling that online learning is expensive (aOR = 1.387, p = 0.001; 95% CI: 0.645–2.130), always experienced poor Internet connection during online learning (aOR = 3.380, p = 0.001; 95% CI: 1.935–4.826), and having no motivation toward online learning (aOR = 3.154, p = 0.001; 95% CI: 2.372–3.936) acted as risk factors for having psychological distress.

CONCLUSION: Cost and Internet access barriers as well as low motivation during the abrupt shift to implementation of online learning in the current pandemic situation acted as risk factors for psychological distress among nursing students.
Bourgs et campagnes normandes aux XI e -XII e siècles
Authors: Lemoine-Descourtieux Astrid
Published: June 2022

La frange méridionale du diocèse d’Évreux connut une dynamique particulière aux xi e - xii e  siècles, corrélée à la défense de la frontière étatique du duché de Normandie. Son évolution est également liée à la forte pression démographique et à la croissance économique que connut la région à la même époque. Le phénomène urbain s’y illustra par la fondation progressive de bourgs associés aux principaux châteaux de la frontière. Le dispositif juridique du droit de bourgage porta non seulement la croissance et la monétarisation de l’économie mais également le développement agricole, celui-ci venant à son tour soutenir les échanges commerciaux. Les espaces ruraux liés aux bourgs de l’interfluve Iton-Avre formèrent ainsi des terroirs propres, nettement séparés de l’habitat. Certains sont encore reconnaissables aujourd’hui et sont documentés. Régi par une coutume spécifique, ce modèle économique perdura malgré des limites rapidement atteintes avec la guerre et la fin généralisée de la croissance.
Un exemple rare de maison rurale solognote médiévale en pan de bois d’une pièce à Lailly-en-Val (Loiret)
Authors: Bontemps Daniel
Published: June 2022

La maison paysanne médiévale d’une pièce en rez-de-chaussée peut subsister ici ou là sous la forme de vestiges souvent difficiles à extraire du tissu des villages ou des fermes. Et de fait elle est difficile à étudier. Souvent en maçonnerie, certaines d’entre elles étaient en pan de bois. C’est donc une telle et rare maison solognote conservée sise à Lailly-en-Val (Loiret) et datée de la fin du Moyen Âge par la dendrochronologie, qui par ailleurs à mis au jour une importante reprise durant le Grand Siècle, que l’on s’est proposé de faire connaître. Parallèlement, afin de mieux comprendre les modalités de constructions de telles maisons nous proposons quelques marchés originaux passés devant notaire du milieu du XVI e  siècle dont Bernard Edeine l’historien-ethnologue de la Sologne pressentit l’existence. Ces documents ont également pour autre vertu de signaler que ces maisons nécessitaient l’intervention systématique d’un maçon et d’un charpentier conformément à la division du travail en corps de métiers distincts sous l’Ancien Régime.
André Rebouças, abolitionniste brésilien du XIX e siècle
Authors: Urbinati Inoã Pierre Carvalho
Published: June 2022

L’influence française au Brésil impérial, bien connue de l’historiographie brésilienne, s’exerça aussi au sein des idées tournées vers le secteur agraire. Ce phénomène peut être particulièrement appréhendé à partir de l’étude des écrits du libéral et abolitionniste André Rebouças (1838-1898) qui fit plusieurs références aux auteurs physiocrates, tels que Jacques Anne Robert Turgot (1727-1781) et Pierre Samuel Dupont de Nemours (1739-1817). Nous examinerons ici en quelle mesure ces références aidèrent Rebouças à construire son projet agraire, ayant comme base l’acquisition de la propriété foncière comme moyen de progrès social, et nous chercherons à montrer comment Rebouças adapta le programme physiocrate au contexte brésilien de la fin du xix e  siècle, marqué par l’ascension du mouvement pour l’abolition de l’esclavage.

La Belle Époque concentre nombre de revendications ouvrières en France. Les campagnes ne sont pas en reste comme le montrent les mouvements emblématiques des vignerons du Midi. Dans les Landes forestières, les gemmeurs, ou résiniers, s’organisent et se structurent à travers des organisations syndicales. Ils conduisent ainsi plusieurs mouvements sociaux d’envergure en 1906 et 1907, qui bousculent des rapports sociaux anciens et complexes. En tentant d’améliorer leurs conditions, ces ouvriers de la forêt se construisent également une identité.

A multi-strategy firefly algorithm based on rough data reasoning for power economic dispatch
Authors: Zhou Ning , Zhang Chen , Zhang Songlin
Published: June 2022

Dynamic economic dispatch (DED) is a multi constraint and nonlinear complex problem, which is embodied in the dynamic decision-making coupled with each other in time and space. It is generally transformed into a high-dimensional multi constraint optimization problem. In this paper, a multi Strategy firefly algorithm (MSRFA) is proposed to solve the DED problem. MSRFA puts forward three strategies through the idea of opposite learning strategy and rough data reasoning to optimize the initialization and iteration process of the algorithm, improve the convergence speed of the algorithm in medium and high dimensions, and improve the escape ability when the algorithm falls into local optimization; The performance of MSRFA is tested in the simulation experiment of DED problem. The experimental results show that MSRFA can search the optimal power generation cost and minimum load error in the experiment, which reflects MSRFA superior stability and ability to jump out of local optimization. Therefore, MSRFA is an efficient way to solve the DED problem.
Asymmetrical herding in cryptocurrency: Impact of COVID 19
Authors: Bharti  , Kumar Ashish
Published: June 2022

This paper examines the evidence of herding in the revolutionary cryptocurrency market for the period from January 2017 to December 2020. The study employs quantile regression technique for investigating herd behaviour during market asymmetries of rising and falling returns, extreme market returns, high volatility, and the exogenous event of the COVID-19 pandemic. The results provide evidence of pronounced herding during the bull phase, extreme down-markets, and high volatility. These results indicate that herd hunch is prevalent in the cryptocurrency market as investors exhibit imitation while ignoring their own knowledge and beliefs. Also, the phenomenon is more vividly observed during the panic period of COVID-19.
Les Fontaines monumentales en Afrique romaine
Authors: Lamare Nicolas
Published: June 2022

Les fontaines monumentales constituaient des marqueurs essentiels du paysage urbain de l’Antiquité. Dans les villes du Maghreb romain et tardo-antique, elles occupaient une place privilégiée que leur accordaient peu d’autres régions de l’empire. Cet ouvrage prend en considération les provinces romaines d’Afrique, entre Atlantique et Tripolitaine, au cours des six premiers siècles de notre ère.

Les analyses et les résultats de cette recherche se fondent sur un catalogue d’édifices et un corpus épigraphique inédits. Soulignant les enjeux passés et présents dans l’étude de l’hydraulique antique, l’enquête retrace l’histoire des explorations archéologiques en Afrique du Nord, pour s’intéresser ensuite aux relations entre terminologie et classifications typologiques modernes et dresser un tableau de l’évolution morphologique des fontaines monumentales antiques. L’analyse technique et architecturale des édifices constitue le cœur de cette étude qui prend également en compte la gestion des aménagements hydrauliques et la perception des fontaines dans le tissu urbain.

Il s’agit ici de considérer les fontaines monumentales comme des composantes de la ville et du réseau hydraulique. Cette réflexion envisage ainsi l’ensemble de la circulation et des usages de l’eau et ambitionne plus largement de penser la civilisation urbaine, les aménagements de la ville antique et ses transformations sur la longue durée.
Crise du Covid-19 et crises immobilières : le débat sur la maison individuelle
Authors: Ghorra-Gobin Cynthia
Published: June 2022

L’article propose d’établir un parallèle entre deux crises, la crise sani­taire de 2020 en France et aux États-Unis et la crise immobilière de 2008 aux États-Unis. Ces deux crises ont en commun un débat sur les modes d’habiter centré sur la maison individuelle. Si les médias soulèvent une question de société, les arguments avancés se limitent à reprendre les termes d’un débat antérieur. La maison individuelle est instrumentalisée au profit d’un plaidoyer confortant des position­nements bien connus.
Loin de masquer le monde, la Covid-19 l’a démasqué. Tectonique des peurs et biopolitique
Authors: Chopplet Marc
Published: June 2022

Depuis les débuts de la pandémie du Covid-19, il fut peu question des peurs. Elles constituent pourtant une des dimensions essentielles des politiques, des comportements, individuels ou collectifs, des affects et des réactions. Conjointes à d’autres inquiétudes sociales, techno­logiques et environnementales, elles nous confrontent à une véri­table tectonique des peurs grandes et petites, intimes et collectives, génératrices au quotidien de violences, de colères, de lassitudes ou d’apathies. S’il est difficile de se projeter dans l’après crise et d’ima­giner ce que les sociétés en retiendront, il semble qu’elle fut l’occa­sion de remise en question des biopolitiques néo-libérales qui avaient conduit à la pénurie en matière de santé tout en imaginant se situer hors d’atteinte de tels risques. Qu’en est-il ? Plus qu’à un exercice d’évaluation des politiques publiques, c’est ici à une réflexion sys­témique globale sur le sens et les orientations de la biopolitique au temps du Covid-19 et des nouvelles peurs, que cet article invite.

Face à l’incertitude, cette popu­lation consulte massivement les supports numériques des autorités internationales et nationales, et elle se mobilise aussi davantage au service du signalement de la désinformation sur les réseaux sociaux numériques (RSN).
La communication au secret : comment la DGSE a remodelé son image publique
Authors: Blistène Pauline
Published: June 2022

Le présent article retrace la lente conversion de la Direction générale de la sécurité extérieure (DGSE) aux logiques de la communication depuis les années 1990 jusqu’à sa collaboration très publicisée avec l’équipe de la série Le Bureau des légendes (Canal + 2015-2020). Il interroge la tension née de la nécessité à communiquer et de l’impossibilité — structurelle, stratégique — du service de rensei­gnement à communiquer sur ses activités réelles. S’appuyant sur des informations en accès libre (presse, documentation historique et technique)et des entretiens conduits avec les professionnels du renseignement français, cet article montrera que loin d’être une évolution naturelle de la DGSE, la collaboration avec l’équipe du BDL a constitué une étape importante dans la formalisation d’une stratégie de communication du service, inspirée notamment de l’exemple américain. En particulier, une telle collaboration a permis à la DGSE de résoudre le paradoxe né de l’injonction à commu­niquer et de la nécessité absolue de conserver le secret sur ses activités réelles grâce à un simulacre de mise en transparence sous couvert de communication politique.

Published: June 2022

Background:

The multifactorial etiology of acute respiratory failure (ARF) often complicates diagnosis at an early stage of clinical presentation. Despite being a common life-threatening disorder, accurate and timely diagnosis is hindered by bad quality of bedside radiographs and nonavailability of immediate computed tomography imaging. This study was an attempt to evaluate the diagnostic accuracy of ultrasound in diagnosing ARF.

Methods:

This hospital-based cross-sectional study investigated the underlying etiological factor in 130 patients presenting with ARF and admitted to the intensive care unit. Lung ultrasound was performed according to the Bedside Lung Ultrasound in Emergency (BLUE) protocol. The diagnostic accuracy of lung ultrasound by emergency protocol was measured against each final diagnosis.

Results:

The mean age observed was 49.28 ± 14.9 years among the cohort. Of the 130 patients, pneumonia was the most common cause of ARF, seen in 42 patients. Breathlessness (56.15%) and fever accompanied by cough (25.38%) were the chief complaints. Diagnostic accuracy of ultrasound lung emergency protocol was 95.38% in the diagnosis of pulmonary edema, 100% for pneumothorax, 93.85% for pneumonia, 96.92% for chronic obstructive pulmonary disease, 99.23% for pulmonary thromboembolism, and 95.38% for acute respiratory distress syndrome.

Conclusion:

Lung ultrasound is a reliable modality that provided accurate and timely diagnosis of ARF in this study. Therefore, BLUE protocol is feasible, easily implementable in the intensive care unit, and must be scaled up in respiratory health-care settings.

Authors: Oh Daeseok , Lee Hyun-Seong
Published: June 2022

Ultrasound provides direct visualization of blood vessels and soft tissues around the sympathetic chain and potentially minimizes injury to these critical anatomic structures when performing stellate ganglion block (SGB). We report an atypical left vertebral artery course detected during an ultrasound prescan before performing a SGB. The left vertebral and inferior thyroid arteries were identified on the longus colli muscle's ventral surface at the C6 level. This report was the first to demonstrate ultrasound images of a vulnerable vertebral artery to intravascular injection. The study emphasized the importance of identifying the sonoanatomy before performing procedures involving the anterior cervical vertebrae.

Published: June 2022

Background:

Central venous catheter (CVC) placement is a frequently performed procedure in the emergency department (ED). We aim to compare two different ultrasound (US)-guided techniques, the short-axis (SAX) approach and the oblique axis (OAX) approach for the insertion of internal jugular vein (IJV) catheters in an ED setting.

Methods:

This prospective, observational study was conducted in the ED of a single tertiary care teaching hospital on patients requiring IJV cannulation. CVC placement was done using both the SAX and OAX approaches as per the ED physician's discretion. Outcome measures included acute complications, successful insertion of an IJV catheter, number of attempts, and access times. The Chi-square test was used to compare the study variables (acute complications, number of cannulation attempts, and successful cannulation) between the two approaches. Mann–Whitney U-test was applied to compare the mean differences of flash time and cannulation time.

Results:

Sixty patients were enrolled, of which 30 underwent IJV cannulation by the SAX technique and 30 by the OAX technique. We noted a total of 22 acute complications, 56.7% in the SAX group and 16.7% in the OAX group. A significant incidence of posterior venous wall puncture was noted in the SAX group (50.0%). No significant statistical differences were noted on analysis of other outcome measures.

Conclusion:

The OAX approach is a useful alternative technique to IJV cannulation in the ED setting. Further multicentric studies in this domain will be required to consider this technique as the primary approach to US-guided IJV cannulation in the ED setting.

Background:

Endometrial cancer is the most common gynecological cancer among women in developed countries. Sono-elastography is an extended ultrasonographic technique that has been shown to be useful in a wide range of conditions ranging from breast, prostate, and thyroid nodules to chronic liver disease and musculoskeletal conditions. The aim of this study is to compare the sonoelastographic features of endometrial malignancy and normal endometrium.

Methods:

This case–control observational study was conducted at a single institution. Participants with histologically proven endometrial cancer according to the results from microcurettage or hysteroscopic biopsy and scheduled for total hysterectomy were included as cases, while asymptomatic women scheduled for routine screening ultrasound examination were recruited as controls. Both cases and controls underwent conventional B-mode transvaginal ultrasonography and strain elastography. Demographic, ultrasonographic, and histopathologic findings were analyzed.

Results:

A total of 29 endometrial cancer patients (cases) and 28 normal females (controls) were included in the analysis. There was no significant difference in the mean age between the two groups, but the mean body weight was significantly higher in the case group (P < 0.001). The strain ratio and elastographic thickness ratio of the endometrium were statistically significantly different between the case and the control group (P ≤ 0.05) due to increased endometrial stiffness in cancer patients as compared to the normal group.

Conclusion:

Our results suggest that endometrial cancer can result in increased stiffness that is detectable by transvaginal sonoelastography. Sonoelastography may serve as an adjunct to conventional ultrasound in evaluating the endometrium of women with abnormal uterine bleeding.
Splenic Infarction Diagnosed by Contrast-enhanced Ultrasound in Infectious Mononucleosis – An Appropriate Diagnostic Option
Authors: Reichlin Mélanie , Bosbach Simon Johannes , Minotti Bruno
Published: June 2022

Infectious mononucleosis is caused by Epstein. Barr virus (EBV) infection. Although typically self.limiting, complications such as splenic infarction and splenic rupture are described. A 17.year.old man presented in the emergency department due to a 3 days history of fever with chills, soreness, fatigue, and loose stool. Ultrasound examination showed a homoechogenic splenomegaly. Viral enteritis was diagnosed and the patient was dismissed. Six days later, he reassessed due to increasing left upper quadrant abdominal pain. Ultrasound showed inhomogeneous splenomegaly with irregular hypoechogenic subcapsular lesions. Contrast.enhanced ultrasound (CEUS) characterized the lesions as not perfused tissue until the late venous phase, compatible with spleen infarctions. Serologic studies were positive for EBV. In the literature, splenic infarction is considered under.recognized. Contrast.enhanced computed tomography (CECT) and magnetic resonance imaging are associated with costs and radiation (CECT). B.mode ultrasound examination is usually used as the first imaging modality, although showing a poor sensitivity in the question of splenic lesions/infarctions. CEUS has shown instead very good sensitivity and does not harm. Therefore, we recommend CEUS examination as the first imaging modality if suspicion of spleen infarction arises, especially when B.mode ultrasound is normal.
Tasavvufî Tefsirlerde Nûr-ı Muhammedî Düşüncesi -Tüsterî, Baklî ve Bursevî Tefsiri Örneği-
Authors: İNCE Eyüp
Published: June 2022

Bu araştırmada, nûr-ı Muhammedî diğer bir ismiyle hakîkat-ı Muhammediyye kavramı incelenmiştir. Çalışmanın amacı ise Tüsterî, Baklî ve Bursevî’nin yorumlarındaki nûr-ı Muhammedî düşüncesinin daha önce çalışılmamış yönlerini ortaya koymaktır. Zira tasavvufun ilk dönemlerinde yaşayan Sehl b. Abdullah Tüsterî (ö.283/896) nûr-ı Muhammedî kavramını ilk dile getiren mutasavvıflardan sayılmıştır. Daha sonra bu düşüncenin izleri, mutasavvıf Rûzbihân Baklî (ö.606/1209) ve İsmail Hakkı Bursevî (ö.1137/1725)’de görülmüştür. Çalışmada söz konusu kavramın mahiyeti, tarihî serüveni, savunucuları ve dayandırıldığı âyetler Tüsterî, Baklî ve Bursevî’nin yorumları çerçevesinde ele alınmıştır. Konu ele alınırken öncelikli olarak Tüsterî’nin nûr-ı Muhammedî düşüncesine referans gösterdiği âyetler ve onların yorumları temel alınmıştır. Daha sonrasında bu âyetlerin yorumu Baklî ve Bursevî’nin tefsirinden incelenerek mukayese yapılmıştır. Bunun neticesinde ise üç müellifte nûr-ı Muhammedî düşüncelerini temellendirdikleri âyetler acısından farklıklar bulunduğu gözlemlenmiştir. Fakat üçünde de Peygamber Efendimizin zâhirî boyutun yanı sıra bâtınî boyutunun var olduğu düşüncesi bariz bir şekilde görülmektedir. Bazı âyetlerin nûr-ı Muhammedî ile bağlantı kurularak yorumlanmasının temel sebebi bu düşünce olduğu söylenebilir.

Research on workplace violence in the health sector in India is emerging. This paper reports on a study on violence against nurses working in hospitals in Bangalore, India. A descriptive cross-sectional study was undertaken with both qualitative and quantitative approaches. The respondents were female nurses working in hospitals located in Bangalore city, India. Data was collected through a self-administered questionnaire, completed during the period from May-June 2017. Of the total of 175 nurses requested, 110 (62.8%) consented to participate in the study. Over a six months period preceding the interview, 33.6% of the respondents faced at least one type of violence. The overwhelming majority (73%) experienced verbal only violence; the rest experienced multiple violence that included verbal, physical and sexual. The factors associated with workplace violence were stressful conditions, miscommunication, excessive workload, lack of security, and working alone. The majority of the assaults were not reported.  The study concludes that policies and intervention programs need to be developed towards making a work environment free from violence.

Thermal cameras are useful devices that are used in many different situations, such as quality control, system maintenance, structural repair, security, medical, monitoring, treatment and diagnose human health or to research and develop advanced technological components. It provides visual temperature information that cannot be perceived by the human senses. Gade & Moeslund (2014) specified that Thermal cameras are passive sensors that capture the infrared radiation emitted by all objects with a temperature above absolute zero. This type of camera was originally developed as a surveillance and night vision tool for the military, but recently the price has dropped, significantly opening up a broader field of applications. Our study shows With basic functions that can be used such as non-contact body temperature measurement, maintenance, maintenance, quality inspection and repair of electronic, electromechanical, telephone, chip, IC, over temperature detection, electrical system lines, underground cables, recessed walls, utilities, gas leak detection, ventilation furnaces, fireplaces, etc., the device can be a useful and effective civil tool.

When applied in areas such as self-driving cars, where deep learning has been utilized, and the results are the best and most up-to-date currently available. In some situations, such as recognizing objects and playing games, deep learning performed significantly better than people did. One more industry that appears to have a lot to gain from deep learning is the medical field. There are a lot of patient records and data, and providing individualized care to each patient is becoming an increasingly important priority as a result. This indicates an immediate need for methods that are both efficient and reliable for processing and analyzing health informatics
IoT Based Blockchain Temperature Monitoring and Fake Medicine Prevention
Authors: Jammula Mounika
Published: June 2022

he Target of today’s healthcare system is delivering medicine directly from the manufacturer to end-user. The pharmaceutical supply chain involves distributors, manufacturers, wholesalers, and customers. The biggest challenge related to this supply chain is temperature monitoring also as counterfeit drug prevention. Many drugs and vaccines remain viable within a selected range of temperatures. If exposed beyond this temperature range, the drugs do not work as intended. Many of the world’s top-selling medicines are sensitive and need cold-chain shipping, i.e., storing goods during a temperature-controlled environment. Keeping the drugs cold is an important a part of the availability chain that connects drug producers to patients. But storing the essential information associated with cold-chain shipping in centralized databases is often susceptible to manipulations or data hacks. Also, the present software doesn't have tracking capability of maintaining a full chain of identity. One of the most reliable solutions would be the integration of IoT sensors with blockchain. To store the essential information related to cold-chain shipping in a blockchain network so, it becomes impossible for the data to get manipulate by anyone unlike centralized databases.
