The decomposition temperature of CaSO4 slag is very high. There is no temperature limit to using supercritical carbon dioxide to lift it from the solar field to the decomposing waste reactor. However, the higher the temperature, the more the losses by radiation are. The situation makes the use of solar resources difficult or even impossible. Therefore, a reaction medium containing calcium chloride and some precursors was proposed. Feasibility and products predictions were performed by the thermodynamic studies, the thermogravimetric technique analysis, and the X-ray diffraction verification. Consequently, the pyrometallurgical process based on the treatment of mixtures of CaSO4 with carbon or silica show reacts at temperatures achievable with renewable energies, which are evaluated by thermogravimetric analysis from respectively 500Â°C and 750Â°C. On the other hand, the outcomes of XRD analysis give an RIR rate of calcium sulfide (CaS) of about 33% (27% with silica). Therefore, the (CaS) compound leads smoothly to sulfur dioxide used in the electrolysis process. Therefore, sulfuric acid and hydrogen are usual value-added products from Westinghouse electrolysis. Indeed 1/3 of the sulfuric acid produced helps generate H2S, and finally, the elemental sulfur will yield spontaneously.

Introduction: Urothelial carcinoma (UC) is the most common histological type of bladder cancer. Around 75% of bladder cancers are classified as pure UC, and 25% are urothelial and nonurothelial histological variants. Sarcomatoid UC is a rare variant, accounts for 0.1%â€“0.3% of all urothelial carcinomas of bladder. It is a biphasic malignant neoplasm with morphologic and immunohistochemical evidence of both epithelial and mesenchymal differentiation. Objective: To study the histomorphological and immunohistochemical features of sarcomatoid urothelial carcinoma. Methods: We received TURBT (Trans Urethral Resection of Bladder Tumor) specimen for histopathological evaluation in the department of pathology, DY Patil medical college, Kolhapur. Routine tissue processing of bits was done and H & E stained sections were subjected for detailed microscopic evaluation and various immunohistochemical markers were applied on the paraffin embedded tissue blocks. Results: A95years old female patient presented with hematuria and anemia.On cystoscopy polypoidal lesion seen in the lateral wall of urinary bladder.No history of previous surgery on urinary bladder.TURBT done. On gross, there were multiple, irregular, grey white strips of tissue altogether weighing 160gms. On microscopy, neoplasm with papillary architecture was seen invading lamina propria. Chondromyxoid, rhabdoid and malignant fibrohistiocytic tumor like areas noted. Immunohistochemical workup revealed positive staining with cytokeratin, vimentin and GATA3 and negative with H-Caldesmon, SMA and Myogenin. Conclusion: Sarcomatoid UC is seen in elderly. Morphologically, the lesion mimics sarcoma, immunohistochemistry workup aids in definitive diagnosis, as it has poor prognosis compared to pure UC.

Forward osmosis (FO) has gained attention of people in recent decades due to its magnificent properties andless energy requirements. This paper aims to discuss various characteristics of draw solutes which are differentiated due to their performance and show exceptional results as osmotic agents in FO. Different types of membranes are being selected for different applications according to needs and requirements. Among them, CTA (Cellulose Triacetate Membrane) and TFC (Thin-film composite membrane) membranesare widely used and show higher fluxas compared to others. Responsive draw solute causes remarkable change in osmotic pressure of the diluted solution when exposed to external factors such as pH and temperature. Responsive and Non-responsive draw solutes have advantages and disadvantages on their usage in FO. Comparative study has been done which shows that as compared to the different techniques for purification, FO stands tallest in terms of economic analysis and alsoresults shown by FO are phenomenal. This review targets recent progress, challenges and opportunities concerning the development of appropriate and efficient osmotic agents with low-cost energy recovery to achieve largescale application of FO and its future development.

Background and Purpose:Stroke is a devastating and major disabling disease affecting 15 million people worldwide per year and causing 6 million deaths annually (the third leading cause of death after cardiovascular and cancer disease). One in six people worldwide suffers from a stroke in their lifetime.This study aims to find the clinical profile, risk factors, and radiological profile of stroke patients in Southern Kashmir of India. Which will be beneficial for taking various preventive measures and planning treatment protocols for stroke patients in the future. Methods:This is a retrospective observational study carried out in south Kashmirfrom August 2016 to February 2020. Stroke was diagnosed clinically and confirmed by Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) and Lumbar Puncture (wherever needed). Results:There were 1632 stroke patients (males 64.82% and females 35.18%) in the age group of 24-85 years. A large number of stroke patients (30.39%)were in the age group of 51 to 65 years. The most common presentation of these stroke patients was hemiplegia (64.58%),dysarthria (55.84%), and altered sensorium(30.14%). The dominant risk factors observed were hypertension (69.54%), smoking (65.93%), and dyslipidemia (23.48%). The most common type of stroke was hemorrhagic stroke (67.27%) whereas ischemic stroke and subarachnoid hemorrhage were observed in 28.55% and4.16% of patients respectively. The most common site of hemorrhage in hemorrhagic strokewas at basal ganglion (44.34%) whereas the parietotemporal areawas the most common affected area in ischemic stroke(40.18%). Conclusions:Hemorrhagic strokes are more common in Kashmir because of peculiar social, environmental, and unique food habits causing hypertension and dyslipidemia.In addition, environmental pollution especially during winters also contributes to this type of stroke.The younger generation is becoming increasingly vulnerable to strokes because of extreme stress conditions due to turmoil and unemployment.Furthermore, a sedentary lifestyle, increased use of junk foods, and lack of exercise in winter also add to the risk for stroke. Hemorrhagic and ischemic strokes were more common in maleswhereassubarachnoid hemorrhages are more common in females. Hospital mortality is higher in males in all three types of strokes. Higher hospital mortality in all strokes was associated withmultiple risk factors and an ICH score of 4 or 5.

The eighteenth and nineteenth century are the most resplendent period in the history of India. During this time, India witnessed the holistic reawakening of the people in the world of new ideals, new thoughts and aspirations in every dimensions of life. The regeneration of India got its expression in Bengal and so this resurgence is called Bengal Renaissance Movement. Ishwar Chandra Vidyasagar played a prominent and vital role in Bengal Renaissance. He also advocated individual liberty and freedom of the press. He was a staunch fighter for the rights and honour of women .Vidyasagar realized a change may be said to have come over the spirit of the times and this may be reckoned as a new era in the history of education on Bengal. He also propagated the ideal from the Shastas ,KanyapyebamPalaniyasikshaniyaitayatnatah- Daughters also are to be reared up and educated with care together with sons. Vidyasagar left no stone unturned to unfetter women from the bondages. He also fought for widow remarriage, abolition of polygamy, child marriage and female education. Educated women are the weapons who yield positive impact on the Indian society through their contributions of home and professional fields. Education as means of empowerment of women can bring about a positive attitudinal change. Vidyasagar was pioneer in woman empowerment who realized way back in 18 th century that unless and until resurrection and empowerment of woman is done reform or renaissance was impossible to bear fruit in the society.

Background:Distance learning contributed significantly to the lived experiences of parents with children. The pandemic brought a sudden shift of school to home-based learning. Children are not yet mature enough to handle distance learning independently, while parents have to juggle workloads and family affairs, thereby experiencing challenges. Method: To better understand the lived experiences of Filipino parents regarding the sudden shift to distance learning, a qualitative phenomenological study was used. With the central question What are the common struggles and coping strategies of Philippine School Doha parents on the institutions distance learning education program?. The researchers conceived twenty-five developmental questions, which were asked to the participants during the semi-structured interviews. The collected data were transcribed and analyzed into themes. Findings: Filipino parents lived experiences towards the shift to distance learning can be divided into three main themes, namely Capability, Adaptability, and Productivity. Conclusion: A parents role and impact on childrens success in the online set-up are crucial yet required. Parents serve as a coach for their children, which lead students through their learning process. The capability to adapt by parents to the newly changed routine during a pandemic shows that many coping strategies are effectively working. Many parents have struggled but conquered hardships in terms of investments in necessary technologies and allowing time for their childrens studies. Enriching knowledge to students in distance learning has further enhanced their abilities, and some parents receive outstanding results from their children. Equally benefiting both parties increases the vote for distance learning more than face-to-face classes, which in conclusion, parents and students most likely prefer distance learning. Recommendations: The researchers recommend interviewing working or non-working parents with children attending distance learning and experiencing the new learning modality that affected their lifestyle and decisions.

In order to obtain the effect of material characteristics of explosive on the formation of collinear explosively formed projectile (EFP)from warhead with dosuble liners, the LS-DYNA simulation software was used to simulate and analyze the forming process of collinear EFP from warhead with five explosive materials including pe4booster, PETN, TNT, C4 and B explosives. The results indicate that with the increase of density, detonation velocity, and detonation pressure, the velocity and the length diameter ratio of the front EFP and rear EFP increase with different laws. With the increase of explosive material density, the velocity and the length diameter ratio of EFPs increase gradually, but the increasing rate decreases gradually. As the detonation velocity increases, the velocity of EFPs increase gradually, but the increasing rate decreases gradually. The length diameter ratio of EFPs decreases first and then increases gradually, showing an "s"-shaped change law. With the increase of explosive detonation pressure, the velocity of EFPs increase gradually, but the increasing rate decrease gradually. The length diameter ratio of the front EFP shows a parabolic growth law with the increase of detonation pressure, and the length diameter ratio of the rear EFP shows an "s"-shaped change law with the detonation pressure.

Underwater robotic arms are important devices that enables workers to carry out tasks remotely from a safe distance reducing or eliminating the risks that are involved with the task. The primary objective of the robotic manipulator is to perform maintenance and cleaning activities of the hull of a ship. However, the control of these devices underwater is quite complicated due to the numerous factors that make these systems unstable and non-linear. The aim of this study is to develop a multibody dynamic robotic manipulator model, integrated with a control strategy to optimize and obtain stable kinematics solutions. The hydrodynamic forces are integrated to the manipulator model considering buoyancy forces and surface drag forces. A basic algorithm is used to generate the joint angles using 7 geometrical parameters. The control of the manipulator was done to simply follow any path that represents the given coordinates. The P, I and D parameters are tuned individually to optimize the kinematic solution of the manipulator. 3-DOF articulated manipulator is the commonly used manipulator configuration. However, a 6-DOF manipulator configuration was selected in this study to allow for change in orientation using wrist motions.

Authors: Ding Junyan , Jiang Cuixiang
Published: February 2022

In actual engineering, asymmetric flow often occurs, but rigid partitions are often installed in the direction of the flow field and are symmetric in the flow direction. This will result in a deflection angle between the dividing plate and the direction of the incoming flow. The research results show that when the declination angle is low, the partition plate has a limited impact on the system; when the deflection angle is about 10 degrees, the system vibration characteristics will have abrupt changes, the amplitude will decrease, and the vortex frequency will increase; at the deflection angle 10 degrees to 45 degrees As the declination angle increases, the amplitude increases, and the vortex frequency decreases; it can be seen from the motion trajectory that the declination angle changes suddenly after 10 degrees, and the system has a small amplitude between 10 degrees and 25 degrees. That is, in this declination interval, the partition plate has a better control effect on the vibration of the cylindrical system.

To reduce the transmission of shafting longitudinal vibration in surface ships, a design of thrust bearing integrated with internal disc springs is proposed and the longitudinal vibration characteristics of the shafting are studied. According to the structural characteristics of thrust bearing and the deformation characteristics of disc springs, the specific size and combination forms of disc springs in the thrust bearing are designed, and the effective disc springs schemes are achieved according to the static and dynamic design requirements. With the integration of the disc springs into the thrust bearing, the peak of longitudinal displacement response at the base of thrust bearing can be reduced by 10 dB by two schemes of disc springs. The proposed design can effectively suppress the transmission of shaft longitudinal vibration to the hull, which has engineering significance for the longitudinal vibration control of the shafting of the surface ship.

Authors: Kowalski Piotr , Zając Jacek
Published: February 2022

The authors of the paper conducted tests of anti-vibration gloves available on the market (17 types) in accordance with the methodology of the EN ISO 10819: 2013 standard. The main purpose of these studies was to verify the data provided by manufacturers in product specifications and user manuals. Based on the determined values of the vibration transmissibility coefficients, it was found that, despite the certificates held by all the tested gloves, as many as 6 types do not meet the minimum requirements for anti-vibration gloves, and two types achieve properties on the verge of meeting these requirements. Two types of gloves (despite the certificate) did not show any significant vibration damping in the whole tested frequency range. The obtained test results indicate the need to verify the anti-vibration properties of the available certified gloves from unverified suppliers. It also seems necessary to assess the effectiveness of protection of anti-vibration gloves in the conditions of their actual use.

Published: February 2022

Numerical simulation of triaxial test are carried out for soil specimens with varying particle size by DEM analysis under the flexible boundary. For the purpose, soil state characteristics such as shear band formation, variation law and the difference between the global void ratio and the local void ratio are particularly focused. Results shows that the shear band of multi-graded specimen is more difficult to create, but it is thicker than that of single-graded specimen. Overall void ratio changes mostly due to particle movement at the shear band and independent to particle gradation. The shear strength of the multi-graded sample is better than that of the single-graded specimen.

Published: February 2022

Smart radiation device (SRD) based on the asymmetrical Fabry-Perot cavity automatically tune its IR emittance depending on the ambient temperature, making it an ideal choice for thermal control system of spacecrafts. The low solar absorption is desirable for SRD to prevent the spacecraft from overheating by sun light. In this paper, a multilayer highly reflective film with LHk stacking layers is designed to reduce the solar absorptance (As) of the Ag/Al2O3/VO2 structured SRD. The reflective film achieves a high reflection band in ~220 nm bandwidth from 460 nm to 680 nm, which results in a reduction of the solar absorptance by 25.56 % for SRD working at low temperature and 24.27 % at high temperature as the stacking factor k= 5. The simulation results indicate that an economic reflective film with k= 3 can achieve effective suppression of As of SRD, demonstrating the promising potential of the proposed reflective film in thermal control application of spacecrafts.

The measurement of magnetostriction characteristics of grain-oriented electrical steel strip under an external compressive stress has always been a main focus in the process of magnetostriction measurement. There are difficulties in the measurement of magnetostriction, especially under compressive stress, mainly because the thickness of test specimen is small, and the test specimen is very easy to deform under the compressive stress. A weight should be placed on the test specimen to prevent a deformation of the test specimen when the measurement of magnetostriction characteristics under an externally compressive stress according to the IEC/TR 62581:2010. But how much weight and how to place aren’t concerned in IEC standard. In this paper, different weights were placed on the grain-oriented electrical steel test specimen under external compressive stress and zero stress. Through analyzed the measured magnetostriction data under different weights to determine the optimal measurement method of grain-oriented electrical steel strip under compressive stress and zero stress. The purpose of this paper is to find the most accurate and high reproducibility measurement method of magnetostriction, which can truly reflect the magnetostriction performance of grain-oriented electrical steel.

Stroke is one of the most important causes of morbidity and mortality worldwide, with survivors subjected to long-term disability. Stroke is classified as ischemic and hemorrhagic. 87 % of strokes are classified as ischemic. Except for thrombolytic therapy, there is no established treatment to reduce the neurological deficits caused by an ischemic stroke. Therefore, it is necessary to develop new therapeutic strategies designed to improve neurological functions after ischemic stroke. Stem cell-based therapies aim to promote neurogenesis and replacement of lost neurons or protect surviving neurons to improve neurological recovery. Further understanding of the mechanisms by which the stem cells exert their beneficial effect could potentially revolutionize the field. The next decade of stem cell research in stroke needs to focus on. Although still in need of exploration, stem cell treatments for stroke may offer ways to protect and replace neurons to improve outcomes for stroke patients.
