Authors: Bajpai Adarsh , Goutam Pritesh
Published: August 2021

Introduction: The presence of psychiatric illness is an important risk factor for suicide. Attempted suicide is one of the major psychiatric
emergencies. Suicide attempts are considered to be the best predictors of an eventual completed suicide.
Objective:The aim of the study was to explore the Socio-demographic prole and psychiatric diagnosis of the patients with suicidal attempt.
Methods: The study population included those patients who were admitted and being managedfor attempted suicide and brought for psychiatric
evaluation during the period of 12 months (1st Feb 2019- 31 Jan 2020) at L.N.M.C Bhopal. Each patient underwent a detailed psychiatric st
evaluation by a consultant psychiatrist once they were medicallystable.
Result: Among the total patients (N=100), 83% were in the age group 20-39 years. Majority of the cases were female (n=76). 68% cases were
married and majority was of Hindu religion.
Most common method of attempted suicide was by poisoning, by intake of Organophosphates. Depressive Disorder (50%) and Alcohol use
disorder (25%) were the most common psychiatric diagnosis.`
Conclusion: Attempted suicide is widely prevalent in younger age group. It is usually by poisoning and the use of Organophosphates is the most
common in our setting and is commonly associated with Depressive disorder. Hence, psychiatric care is essential for this patient.

leading cardiovascular cause of death . If not treated properly it also leads to chronic pulmonary hypertension and cor pulmonale . Once DVT is
diagnosed treatmet is required and consist of oral anticoagulation and inferior vena cava interruption via lter placement in patients with
contraindication for anticoagulation treatment.
In 2003 ,the U.S .Food and Drug Administration (FDA ) cleared retrievable inferior vena cave lters (rIVCFs) for clinical use , after that its uses
exponentially increases . In parallel with these trends ,there has been growing awareness of device –related complication including fracture ,
penetration to adjuscent structure , migration , thrombosis and some time embolisation of fractured segment in heart that leads to cardiac

Background: Emergence of new diabetes mellitus cases, after infection with SARS Co-V2 is a serious concern. Understanding them and then
following up these cases can enrich our knowledge about the etiopathogenesis of diabetes mellitus, and the diabetogenicity of these viral
infections.
Observation: We had a series of adult Covid 19 cases in our hospitals in north India, during the early summer 2021. They did not have prediabetes
or any predilection to develop diabetes. On admission, they had high blood sugar and needed insulin. After discharge from hospital, they needed
insulin or oral antidiabetic drugs. Eight weeks into follow up, these cases still needed antidiabetic medicines.
Methods: Observational prospective study. Analysis of the past medical history, and comparison with the acute covid and post covid illness.
Results:The analysis of these cases shows that the SARS CoV2 infection results in diabetogenic changes leading to new onset diabetes.
Conclusion: Diagnosis of new onset diabetes must be kept in mind with every case of SARS CoV-2 infection, even after full recovery from acute
covid -19.
A CLINICAL STUDY OF PENETRATING ABDOMINAL TRAUMA WITH SPECIAL REFERENCE TO ITS MANAGEMENT : AN INDIAN SCENARIO
Authors: Singh Saumya , Halder Anindya , Das Niru
Published: August 2021

Introduction: The incidence of penetrating abdominal injuries has been on the rise. The common availability of rearms, the lack of proper law,
armed conicts, civil violence and road trafc accidents are the major causes of penetrating abdominal injuries. As patient with penetrating
abdominal trauma are at risk of harbouring life threatening injuries, early diagnosis and timely intervention is the most important steps to reduce its
morbidity as well as mortality. Recently due to improvement of the present healthcare system, the outcome of these injuries is improving.
Materials And Methods: A descriptive observational study was carried out on 60 cases of penetrating abdominal injuries. A predesigned pretested schedule was used for data collection. Interview of the study subject and evaluation of all clinical reports was done to obtain the history,
clinical ndings, management, complications, mortality and follow up. Before data collection, informed consent was obtained from each and every
study subjects.
Results: The overall incidence of penetrating abdominal trauma was found to be 2.30% of the total admission of 6217 patients in the department of
surgery. The most common cause of penetrating abdominal injury found in this study is stab injury by sharp objects which is followed by gunshot
injury. The commonest age group affected was 20 to 30 years which comprises about 41.67%. In this study we found a male preponderance in cases
of penetrating injury to the abdomen. In most of the cases the mode is homicidal stab or gunshot injury followed by accidental injuries. Pain,
abdominal distension and bleeding from the wound are the main presenting symptom. After initial evaluation with USG (FAST),CTscan abdomen
is the most valuable investigation so far. In this series, it is found that the small intestine is the most commonly involved viscera followed by colon,
omentum, mesentery and liver respectively. Most common complications after operative intervention was wound infection. The average hospital
stay was 6 to 15 days. It has been observed that the post-operative complications, associated injuries and multiple organ injuries are the cause of
increased hospital stay.
Conclusion: Penetrating trauma can be serious because it can damage internal organs and presents a risk of shock and infection. In the present year,
due to overall improvement in the communication and transportation, better monitoring systems and resuscitative measures, improvised diagnostic
methods, better availability of blood and blood products, better medications and more skilful surgical techniques, the outcomes of these injuries are
improving.

Authors: Vargas Riaño Julio Hernando
Published: August 2021

Objective: To implement a prototype specific for human ankle kinematics studies in limited spaces, immobile, or lying down patients. Based on anatomy and anthropometry, using a screw theory model, draw-wire and inertial sensors were employed Methods: We included ankle injury studies to highlight the importance of measuring the in vivo range of motion; we studied the ankle anatomy, biomechanics, and anthropometry to estimate the size and movements of the device. We simulated the biaxial representation of ankle motion through the product of exponential mapping. Finally, we designed a structure based on trilateration by projecting tetrahedrons, an acquisition circuit with firmware and calibration software. Results: The prototype has two main parts: support and adjustable platform. We proposed a method to find the position by projecting three apexes on the base using draw-wire sensors, an acquisition board, a single-board computer, a display, Bluetooth, Wi-Fi, and two inertial measurement units. The power source had battery backup with boost and buck converters. Conclusion: We proposed an ankle model in the screw theory framework, a method for localization, and a novel device for in vivo measurements specific for lying patients on a bed, the ground, outdoors, or remote locations without complex setups. The double-battery management is robust and long lasting. Significance: The device is an alternative for measuring the range of motion in laying down patients. We will use it in modeling, diagnosis, and rehabilitation.

Authors: Ferenza Oktovalen , Tuparjono Tuparjono , Sugiyarto Sugiyarto
Published: August 2021

Welding is a very important part in the development and growth of the industry because it has a role in engineering, repair and construction. Shielded metal arc welding (SMAW) is the process of joining two or more materials using a wrapped electrode as heat energy to melt the material. The purpose of this study was to determine the effect and welding defects that arise with current variations so that the optimal welding results obtained from 3 amperes were tested using E6013 electrode diameter 3,2 at the 3F welding position fillet joint. This study uses an experimental method with the material used is St 37 steel with a current variation of 90A, 100A, and 110A. From the research conducted, it was not found optimal welding results where from each ampere tested there was still a weld defect. The defects that occur in the three amperes are caused by the arc, electrode angle, and arc length that exceed the normal limit and are also influenced by the welding speed. From the three variations of the amperage used, the dominant welding results did not occur, namely the 90 amperage, while the 100 amperage welding leg showed good results.

I never watched the video. The descriptions themselves have always felt like enough. Traumatizing enough. Invasive enough. George Floyd, father of two, laying on the ground, as an unfazed officer kneeled on his neck for at least eight minutes and forty-six seconds. He pleaded for his life and cried out to his deceased mother until he met his inevitable death. His name should be said for the record before saying almost anything else. The recording of the chilling final minutes of his life is, in all probability, one of the impetuses for this multi-journal Reckoning and Reform Symposium.
The Wolf We Feed: Democracy, Caste, and Legitimacy
Authors: Justice Benjamin , Meares Tracey
Published: August 2021

Procedure is central to American public legal discourse. From the soaring rhetoric of the Declaration of Independence to the Due Process Clause of the Fourteenth Amendment, the American legal tradition rests on the principle that law must be both derived and applied according to fair process. Consider that in the 2020 election the Trump Administration resorted to fervent and false allegations of widespread voter fraud—that the election process was fundamentally unfair—in order to weaponize Republican voters’ ostensible commitments to fairness against what was, objectively, one of the least procedurally unfair elections in history. Yet the four-year period of the Trump Administration (2017–2021) also saw the rise of overt and deliberate racist politics and mounting evidence that a universal commitment by all to fairness for all across the United States is a mythical framing of the American creed. One can look from the apparent lack of justice for unarmed Black civilians killed by police officers to a sitting President’s affirmative support for white supremacist groups to observe the doublespeak associated with fascist regimes: claiming to be restoring law and order while backing away from commitments to due process and equal protection. And yet, simultaneously, we have also seen the mainstreaming of a successful oppositional politics, including Black Lives Matter, which in June 2020 enjoyed a peak 67 percent approval rating among American adults in a national survey. Even as white nationalism flourished under the Trump Administration, polls indicate that increasing numbers of Americans acknowledge that our society is unfair to racial minorities. As Americans stand at the perpetual racial crossroads of the twenty-first century, how much does the legitimacy that they accord their government depend on the procedural justice it delivers to all?

Optimization and monitoring of IVF treatments requires good data on the effect and magnitude of clinical factors affecting treatment outcome. Many factors have been known to affect IVF outcomes. Currently there are still no data to predict whether a patient who undergoes In Vitro Fertilization (IVF) cycles can be considered a good candidate for oocyte freezing. The aim of this study was therefore to evaluate which biological and biochemical factors can be predictive of oocyte survival and fertilization, as well as of clinical pregnancy in oocyte thawing cycles. This study showed that none of the factors available on the day of the pick-up is able to predict (in case of oocyte cryopreservation) the success of a subsequent oocyte thawing cycle. Only the transfer of at least one Grade 1 embryo after oocyte thawing cycle has a statistically significant impact on pregnancy. Unfortunately, this cannot be considered an elective factor to guide the clinician and/or the embryologist in choosing patient's treatment as it is not available on the day of the oocyte pick up but it is a result of oocyte thawing.

Influence of Additives on Flexural Strength of Roller Compacted Concrete
Authors: Sarsam Saad Issa
Published: August 2021

Roller compacted concrete is considered as a sustainable solution. In the present investigation, three types of additives namely (fly ash, fumed silica, and hydrated lime) are implemented as partial replacement of Portland cement for preparation of roller compacted concrete slab samples using dense and gap aggregate gradation. The slab samples were prepared at optimum cement requirement of 12 % and at (2 and 4) % cement below and above the optimum. Beam specimens of (38 x 10 x 8) Cm were extracted from the slab samples using diamond saw. The specimens were subjected to flexural strength determination using two testing modes, the three and the four points loading. It was noticed that the flexural strength under four-points loading mode is lower by a range of (0.787 to 0.732) folds than that under three-points loading mode for dense and gap graded mixtures respectively. It was concluded that the flexural strength increases by (96.2, 84, and 17.2) % and (109, 86, and 9.3) % after replacement of (10, 12, and 15) % of cement by hydrated lime while it declines by (50, 64.6, and 77) % and (0.1, 30.8, and 63.5) % after replacement of (5, 7, and 10) % of cement by fumed silica for dense and gap graded aggregates respectively. The flexural strength of dense graded mixtures increases by 63 % at 20 % replacement by fly ash, however, it increases by (99.7, 53.8, and 1.0) % after replacement of (10, 12, and 15) % of cement by fly ash for gap graded aggregates respectively.
Effect of Change in Ambient Temperature on Creep of Concrete
Authors: Kammouna Zainab
Published: August 2021

This article reviews the studies on the effect of temperature on the creep of concrete. Indeed, the temperature is one of the most important factors, as its rise leads to an acceleration of creep of concrete and thus an increase in its value compared to concrete under normal temperature. However, creep increases significantly if concrete under load is exposed to a high temperature. Thus, the creep value becomes higher than that of concrete exposed to a constant temperature (of the same level). Unfortunately, some of the codes for predicting creep of concrete (for instance the Eurocode) do not take into account the effect of high temperature on the creep of concrete under load. To clarify the impact of heating concrete under load (on creep) and distinguish it from its effect where it is constant, this study was carried out.

Le rôle climatique des fronts océaniques de fine échelle en profondeur (prix Prud'homme 2020)
Authors: Siegelman Lia
Published: August 2021

L'océan est le plus grand réservoir d'énergie de notre planète. La quantité de chaleur qu'il est capable de stocker est modulée par sa circulation complexe, opérant sur des échelles allant du centimètre à la dizaine de milliers de kilomètres. Les découvertes scientifiques des deux dernières décennies ont révélé l'existence de fronts de fine échelle (d'environ 1 à 50 km), analogues aux fronts atmosphériques, dans la couche de mélange océanique de surface. Ces fronts agissent comme des conduits entre l'océan et l'atmosphère, contrôlant les échanges de gaz et de chaleur. Combinant observation et modélisation, nous démontrons pour la première fois le rôle capital de ces fronts jusqu'à 1000 m de profondeur. Ils génèrent d'importants flux de chaleur dirigés de l'intérieur de l'océan vers la surface, pouvant modifier la capacité de stockage de chaleur de l'océan, avec des répercussions potentiellement majeures pour les systèmes biogéochimique et climatique.

The ocean is the largest solar energy collector on Earth. The amount of heat it can store is modulated by its complex circulation, which spans a broad range of spatial scales, from centimeters to thousands of kilometers. Scientific discoveries of the past two decades revealed the existence of fine-scale fronts (≈ 10-20 km wide), analogous to atmospheric fronts, in the oceanic surface mixed layer. These fronts control the exchanges between the ocean and the atmosphere just as the capillary vessels of our pulmonary alveoli facilitate the exchange of gas when breathing. Combining observation and modeling, we demonstrate for the first time the crucial role played by these fronts in the ocean interior. These fine-scale fronts drive an anomalous upward heat transport from the ocean interior back to the surface. This can alter the ocean heat storage capacity, with potential major implications for the biogeochemical and climate systems.
On Science and Civilisation in China

When the first volume of Science and Civilisation in China was published in 1954, Chinese scientific and technological accomplishments were largely unknown in the West, even among scientists. The initiator of the series, the British biochemist Joseph Needham, subsequently became one of the most important conduits between Chinese science and the international community.

In spite of the immense advancement in the diagnostic and treatment modalities, cancer continues to be one of the leading causes of mortality across the globe, responsible for the death of around 10 million patients every year. The foremost challenges faced in the treatment of this disease are chemoresistance, adverse effects of the drugs, and the high cost of treatment. Though scientific studies over the past few decades have foreseen and are focusing on the cancer-preventive and therapeutic potential of natural products and their underlying mechanism of action, many more of these agents are not still explored. Piperlongumine (PL), or piplartine, is one such alkaloid isolated from Piper longum Linn. which is shown to be safe and has significant potential in the prevention and therapy of cancer. Numerous shreds of evidence have established the ability of this alkaloid and its analogs and nanoformulations in modulating various complex molecular pathways such as phosphatidylinositol-3-kinase/protein kinase B /mammalian target of rapamycin, nuclear factor kappa-B, Janus kinases/signal transducer and activator of transcription 3, etc. and inhibit different hallmarks of cancer such as cell survival, proliferation, invasion, angiogenesis, epithelial-mesenchymal-transition, metastases, etc. In addition, PL was also shown to inhibit radioresistance and chemoresistance and sensitize the cancer cells to the standard chemotherapeutic agents. Therefore, this compound has high potential as a drug candidate for the prevention and treatment of different cancers. The current review briefly reiterates the anti-cancer properties of PL against different types of cancer, which permits further investigation by conducting clinical studies.

Published: August 2021

This paper proposes a sustainable method to prepare glutaric acid from glucose via an α-keto glutaric acid derived from glucose by fermentation using Corynebacterium glutamicum GKGA. Glutaric acid was prepared from α-keto glutaric acid via the hydrogenation of a 1,3-dithiolane diamide intermediate as the key step. The combination of biotransformation and chemical transformation of glutaric acid provided an efficient and environment-friendly method for the sustainable synthesis of glutaric acid
A Monocot Flower, Mirafloris burmitis gen. et sp. nov. (Monocots: Angiospermae), in Burmese Amber
Authors: Poinar, Jr. George O.
Published: August 2021

A six-merous, slightly bisymmetric monocot flower in mid-Cretaceous Burmese amber is described as Mirafloris burmitis gen. et sp. nov. The perianth is composed of two whorls of 3+3 distinctly vascularized tepals connected by an irregular network of veinlets.  There are two whorls of 3+3 free stamens with latrorse dehiscence positioned opposite the tepals. A single 3-lobed style arises from the center of the flower. Perigonal nectaries are located at the base of the inner tepals. The oval-spherical pollen possess a single, longitudinal suture.  The fossil shows affinities to the order Liliales and family Liliaceae. This is the first showy monocot flower described from Burmese amber and based on recent phylogenetic studies, may be one of the earliest records of a fossil member of the Liliales.

Systemic AA amyloidosis is an uncommon complication of rheumatoid arthritis (RA), especially in poorly controlled RA. Renal involvement caused by deposits of amyloid fibrils derived from acute-phase proteins is represented by nephrotic-range proteinuria ultimately leading to renal failure. We report the case of 27-year-old woman diagnosed with RA, with a history of musculoskeletal involvement since the age of 16, manifested by arthritis involving the wrists, knees and ankles; accompanied by severe and persistent inflammatory syndrome. She presented with an active form of RA complicated with secondary amyloidosis manifested by nephrotic-range proteinuria at the time of admission. Renal biopsy confirmed the presence of amyloid deposits. Anti-TNFα therapy with Certolizumab pegol proved effective in reducing proteinuria and inflammatory biomarker levels in our patient. The efficacy of anti TNF-α therapy in RA complicated with renal amyloidosis is demonstrated by recent scientific data.

Modelling And Simulation of Topical Drug Diffusion in The Dermal Layer of Human Body
Authors: Sudi Mungkasi
Published: August 2021

We consider the problem of drug diffusion in the dermal layer of human body. Two existing mathematical models of the drug diffusion problem are recalled. We obtain that the existing models lead to inconsistent equations for the steady state condition. We also obtain that solutions to the existing models are unrealistic for some cases of the unsteady state condition, because negative drug concentrations occur due to the inappropriate assumption of the model. Therefore, in this paper, we propose a modified mathematical model, so that the model is consistent, and the solution is nonnegative for both steady and unsteady state conditions of the drug diffusion problem in the dermal layer of human body. For the steady state condition, the exact solution to the proposed model is given. For unsteady state condition, we use a finite difference method for solving the models numerically, where the discretisation is centred in space and forward in time. Simulation results confirm that our proposed model and method preserve the non-negativity of the solution to the problem, so the solution is more realistic than that of the old model.
