A multiphase fluid-structure computational framework for underwater implosion problems

The intense implosive collapse of an air-filled underwater structure can lead to ultrahigh compressions. Shocks emanating from this process are a potential threat to a nearby submarine hull, particularly in the presence of UNDEX loading. Therefore, with the projected increase of the number of air-backed volumes external to a submarine hull, implosion has become a source of concern to the Navy who now requires an improved capability to design and qualify submarine external payloads for implosion avoidance and platform survivability. However, the development of such a computational model for simulating payload implosion and predicting platform damage is a formidable challenge. It requires accounting for all of the fluid, gas, and structural aspects of this complex problem as well as their interactions. It also requires incorporating in the computations material and failure models, UNDEX loading, and capturing the precise effects on the pressure peaks of many factors such as the rate of structural collapse, hydrodynamic instability at the fluid/bubble interface, and cavitation when it occurs in the fluid. To this effect, this thesis makes essential contributions to computational mechanics that pave the way for the simulation of implosion and the assessment of platform survivability. These include a novel finite volume scheme for the solution of two-phase gas/water problems characterized by strong contact discontinuities. This discretization scheme is equipped with an exact, v local, two-phase Riemann solver for computing the fluxes at the material interface without crossing it, which makes it robust with respect to a large discontinuity of the density and a strong pressure jump at the material interface. This two-phase flow scheme is also proven to be contact preserving and nearly conservative. To achieve computational efficiency for complex equations of state such as that of Jones, Wilkins and Lee, this scheme is also equipped with a sparse grid method for tabulating and interpolating data relevant to the exact solution of a Riemann problem. The contributions of this thesis also include an exact local fluid-structure Riemann solver for embedded fluid methods, the implementation of all aforementioned CFD methods in a state-of-the-art fluid-structure analysis environment, and the application of the developed computational technology to the simulation of the implosion of aluminum cylinders with diameter-thickness ratio of approximately 54. The obtained numerical predictions are found to correlate well with the results of the corresponding experiments performed simultaneously at the University of Texas at Austin.
Outdoor Positioning Estimation of Multi-GPS / INS Integrated System by EKF / UPF Filter Conversion

: In this Paper, outdoor position estimation system was implemented using GPS (Global Positioning System) and INS (Inertial Navigation System). GPS position information has lots of errors by interference from obstacles and weather, the surrounding environment. To reduce these errors, multiple GPS system is used. Also, the Discrete Wavelet Transforms was applied to INS data for compensation of its error. In this paper, position estimation of the mobile robot in the straight line is conducted by EKF (Extended Kalman Filter). However, curve running position estimation is less accurate than straight line due to phase change in rotation. The curve is recognized through the rate of change in heading angle and the position estimation precision of the initial curve was improved by UPF (Unscented Particle Filter). In the case of UPF, if the number of particle is so many that big memory gets size is needed and processing speed becomes late. So, it only used the position estimation in the initial curve. Thereafter, the position of mobile robot in curve is estimated through switching from UPF to EKF again. Through the experiments, we verify the superiority of the system and make a conclusion.
Performances of Hybrid Renewable Energy Based Electrical Charging Station

Electric vehicles (EVS) represent one of the most promising technologies to green the transportation systems. An important issue is that high penetration of evs brings heavy electricity demand to the power grid systems became an important solution to reach the remote area and maximizing the economic, technological, and environmental benefits. In this thesis, A combination of solar energy, diesel generator, and electric vehicle gave an excellent result to ensure an uninterruptible power supply in case of low irradiance of PV solar energy. The main element is a photovoltaic system that is designed to satisfy the daily load energy requirement. A three-phase active filter is used to improve the power quality, manage the power, and corrected the unbalance. Backup energy storage systems including plug-in hybrid electric vehicles and the diesel generator are used to ensure an uninterruptible power supply in case of low solar irradiation. An effective way to reduce the impact is to integrate local power generation such as renewable energy (RES) into the charging infrastructure. Due to the intermittent and indivisible nature of RES, it has become very challenging to coordinate the charging of electric cars with other grid loads and renewable energy. This studies the charging of electric vehicles with smart grid technology and reviews its interaction with renewable energy. First introduces electric cars and renewable energy, which mainly introduces the main types of electric vehicles and the estimation method for renewable energy. In line with the objectives, the existing research work is divided into three categories: cost awareness, efficiency awareness and emission awareness of the interaction between electric cars and renewable energy. Each discussion category contains a description of the core idea, an overview of the solution and a comparison between different works. Finally, some important open-ended questions related to the interaction between electric cars and RES are given, and some possible solutions are discussed. To take care of the battery life, the PHEV supplies power to the load only during emergencies. This motivates the development of this work to the used robust algorithm, sizing, and energy management to balance the load consumption and electricity production this simulation has performed on MATLAB
Influence of TRPV1 Modulators Capsaicin and Capsazepine on Osteoclastogenesis in vitro

71 www.wjrr. org  Abstract—The influence of TRPV1 modulators capsaicin and capsazepine to regulate the growth and proliferation of osteoclasts and thereby control osteoclastogenesis was studied on murine macrophage cell line RAW 264.7 induced to take up osteoclastic lineage by the addition of RANK (receptor activator of nuclear factor kappa B) ligand. The differentiation of cells of macrophage lineage into osteoclastic lineage upon the addition of RANK ligand was ascertained by TRAP (Tartarate Resistant Acid Phosphatase) staining and subsequent light microscopy analysis. Crystal violet test, Sulphorhodamine B assay, NBT reduction test and Neutral red dye uptake test were taken as end point indicators to assess osteoclast growth and proliferation. It was observed that capsaicin at a concentration of 200μg/ml exhibited a statistically significant increase whereas capsazepine at a concentration of 94. 2μg/ml (IC50 concentration of capsazepine) exhibited a statistically significant inhibition of osteoclast growth and proliferation. Results of the study indicate that both the compounds influence osteoclastogenesis with capsaicin showing a potentiating and capsazepine showing inhibitory effect thereby implicating their ability to influence bone resorption and hence bone remodeling. The compounds could be of therapeutic importance in musculoskeletal diseases and other inflammatory diseases of the bone to regulate the disruption in bone remodeling equilibrium.
Efficacy of Diode Laser Ablation and LLLT on Healing and Bacterial Load Reduction at Intraoral Biopsy Site

Received: Revised: Accepted: ABSTRACT Statement of the Problem: Healing complications after the conventional surgical biopsy procedure along with bacterial colonization indicates scope for sophisticated techniques. Amalgamation of photo-disinfection along with healing properties of diode laser with practiced biopsy technique can help in dealing with post biopsy complications. Purpose: Present study will analyze the possibility of conjugation of conventional surgical biopsy technique with diode laser with regards to its superior properties for achieving better healing and analgesia along with sterilization of the biopsy site. Materials and Method: Randomized control trial was done where Punch Biopsy procedure was performed for homogenous leukoplakia. Patients were randomly divided into Laser group (Test group) and control group. Test group received laser ablation and low level laser therapy (LLLT) on surgical site along with warm saline rinses whereas control group was prescribed with systemic analgesic and antibiotics. Pain on VAS (Visual analogue scale), erythema along with the size of defect was evaluated on day 0, 2 and 4. Swabs were collected from the biopsy site and culture was done for evaluation of bacterial load. Results: Highly statistical significant values indicating laser induced analgesia were obtained after analysis for 2nd and 4th day (p= 0.00). Erythema and biopsy defect size evaluation shows significant results for 2nd day (p value 0.023 and 0.004 respectively) which shows absence of erythema and enhancement of healing in test group compared to controls. Statistical significant results were obtained for estimation of bacterial colonization with p value as 0.00, 0.00 for 2nd and 4th day claiming laser supported bacterial disinfection. There is a significant percentage increase on 2nd (p= 0.013) and decrease on 4th post-operative day (p= 0.022). Conclusion: The results encourage the conjugation of conventional incisional punch biopsy with low level Lasers for avoiding systemic intervention for post biopsy complications.
Open badges - glorified award stickers or valuable learning credentials?

The concept of badges to acknowledge skills and competencies is not new, as anyone who has been in the Scouts or Girl Guides can attest. Historically, they began as a heraldic symbol for medieval knights, were used to denote the completion of a pilgrimage and were a mark of political allegiance. They have also been used to show rank and achievement and as a visual identification of membership (Gibson 2013). The next iteration of the badge came in the shift from the physical (sticker and cloth badge) to the virtual (computer image or icon), resulting in the development of the digital badge. Gaming (for example, World of Warcraft) began using digital badges as a way of showing levels of achievement as the gamer ascended through increasing stages of difficulty. These badges have become very popular, not only for their visual representation of skill mastery, but also their motivational value. While very popular and used in a range of online environments (such as digital courses) to acknowledge achievement and certification, they are, however, limited by their two-dimensional nature. While they constitute a symbolic icon that represents a skill or set of skills, they lack the 'critical characteristics' that would give them real value, both to the earners and the audience reviewing them. Their relevance is limited to the context in which they were achieved (for example, within the Scouts) and there is a lack of mechanism to verify, share and display the badges outside of the context in which they were created (Catalano 2013).
Combating Hidden Hunger through Micro-Nutrient Dense Biofortified Foods

The consumption of biofortified crops by farm households in rural areas help reduction of malnutrition initially and later the urban households as markets develop for these foods. A synthesis of extant literature reveals that these crops provide 35-50% of micronutrients. For children of 4 to 6 years old and for non-pregnant, non-lactating women of reproductive age, biofortification provides an additional 35 percent of the estimated average requirement (EAR) of iron in beans and 40 percent in pearl millet. The additional zinc in wheat and rice provides up to 25 percent and 40 percent of the EAR, respectively. These crops provide the maximum EAR of 50% in case of vitamin A in cassava, maize, and sweet potato. Biofortification is a process of increasing the density of vitamins and minerals in a crop through conventional plant breeding techniques. While fortified foods reach urban areas, rural people consuming staple crop based diets can access biofortified crops. The level of nutrients in biofortified crops cannot be as high as in industrial fortified foods, but can increase daily adequacy of micronutrient intakes. Biofortification complements the existing interventions to provide micronutrients to vulnerable population in a relatively easy, cost effective and sustainable manner. Additionally, predominantly rural nature of poverty and vibrant seed markets place South Asia in an advantageous position in harnessing biofortification. Led by pioneering work of HarvestPlus of the International Food Policy Research Institute with the help of several international organizations, these crops have been diffusing gradually in developing countries. Cultivated by 6.7 million farming households across 14 countries of Africa, Asia and Latin America and the Caribbean in 2017 and benefitting 33 million people, biofortification has a positive impact in reducing hidden hunger especially among lower income groups (Bouis, Saltzman and Birol, 2019). The burden of malnutrition in the world is unacceptably high and is estimated to adversely affect two billion people. The extent of 'hidden hunger' in South Asia is much more widespread than other parts of the world. Anemia among pregnant women (52%) and children of less than five years (58%) in South Asia exceeds the global prevalence (38 and 43%, respectively) as does inadequate zinc intake (at 30% vs. 17%), apart from alarmingly high Vitamin A deficiency to the extent of 31-57% of preschool children. Nearly 45% of children deaths are associated with malnutrition (Harding et al., 2018). Climate change further aggravates this burden of malnutrition in South Asia by reducing iron, zinc and protein in plants like wheat, rice, maize and soybean (Myers et al., 2014). Micronutrient deficiencies result in poor health, low cognitive development, low educational outcomes, work productivity and earnings thereby reducing the total welfare in the society. The situation is much more depressing in India with a huge malnutrition related cost of 9.1 million disability adjusted life years and a reduction of national income by 4%.
‘Why’ without asking, in Romanian

Unlike English, Romanian also allows its ‘why’ wh-expression to introduce non-interrogative wh-clauses. For instance, the bracketed wh-clause in the Romanian sentence in (3) is an instantiation of a clausal construction known as a free relative clause (FR): it is introduced by de ce ‘why’, occurs in a position in which an interrogative clause cannot occur, and is not interpreted as conveying a question, as its English translation makes it clear. The whole sentence in (3) is judged fully acceptable by our Romanian consultants.3 Therefore, FRs introduced by ‘why’ (why-
Case in Point Surgical Management of a Large , Gouty Tophus

Gout is a metabolic disease that occurs when excess amounts of uric acid circulating in the blood crystallize and subsequently deposit in joints or soft tissue. Hyperuricemia is the condition most often associated with an acute gouty attack or, in chronic states, with the formation of tophi. In all cases, the demonstration of monosodium urate crystals in the joint or surrounding soft tissues is sufficient to make a definitive diagnosis of gout. In this article, we describe the case of a patient with chronic hyperuricemia who presented to a VA podiatry clinic with an unusually large, gouty tophus. While management of his condition through medication, dietary changes, and other lifestyle modifications was attempted, surgical intervention eventually was necessary. Among the other notable features of this case was the fact that he was diagnosed with chronic renal failure and nephritic syndrome after developing multiple tophi, whereas such conditions usually are diagnosed before any gouty symptoms manifest. InITIaL ExaM A 56-year-old man was referred to a VA podiatry clinic by his primary care provider (PCP). He presented with a large, indurated mass about his left first metatarsophalangeal (MTP) joint (Figure 1). The lesion was not focally tender, but its girth hindered the patient’s ability to wear shoes. The patient had similar masses and symptoms of intermittent pain and swelling in multiple other joints, including his hands, knees, wrists, and elbows. These lesions had developed over a six-year period prior to his initial clinic presentation. The patient was being treated by his PCP for hypothyroidism (which his PCP described as “borderline myxedema”) and hyperlipidemia. His PCP also previously had detected hyperuricemia and diagnosed him with polyarticular tophaceous gout, for which the PCP prescribed a regimen of allopurinol. The patient could not tolerate this medication, however, and discontinued the regimen after three months of chronic nausea. Colchicine was prescribed but also was not tolerated by the patient. The primary lesion of concern was the tophus surrounding the left great toe. Upon physical examination at the initial clinic visit, the lesion was observed to extend medially and plantarly. It extended distally to the interphalangeal joint of the hallux and proximally toward the plantar medial arch, approximately mid-shaft of the first metatarsal bone. Radiographs revealed a large, contiguous, soft tissue density about the first MTP joint as described (Figure 2). There were no lytic osseous lesions or areas in proximity with diminished bone density. Examination revealed excellent pedal pulses (dorsalis pedis, +2/4; posterior tibial, +2/4) bilaterally with three-second capillary refill to all digits. Tactile and vibratory sensations were intact and normal distally, bilaterally, and symmetrically.
Knowledge, Attitude and Practice of Medical Practitioners towards Standards of Tuberculosis Care through Private Public Partnership working in neighbouring districts of Kerala and Karnataka

More than 60% of the TB patients approach the private practitioners in India. To achieve control over rapid rise in prevalence of TB in India, involving the private practitioners as key stakeholders should remain the main objective of the Government of India. Aim: To assess and discuss the involvement of private practitioners in the diagnosis, treatment and control of TB in the neighboring districts of Kerala and Karnataka. Objectives: To assess the Knowledge, Attitude and Practices of Medical Practitioners towards Standards of Tuberculosis Care (RNTCP Programme) through Private Public Partnership working in neighbouring Border Districts of Kerala and Karnataka. Methods: A Cross-sectional Study by using a self-administered questionnaire was conducted among 100 Private and Government practitioners. The study questionnaire was sent to 100 doctors out of which 94 practitioners participated. Data was collected and analysed. Among the 94participants, 90 (95.74%) were prescribing anti TB drugs. 04 (04.25%) reported as not prescribing Anti TB Drugs. 46/90 (51.11%) were giving prescription for four standard drugs with appropriate dosages and duration. 14/90 (15.55%) practitioners were not following the anti TB regimen advised by national programme . 30/90 (33.33%) practitioners did not answer the questions related to prescribing practices adopted by them. 68/90 (75.55%) practitioners anti TB treatment was given for 6 months. 06/90 (06.66%) practitioners answered as 1 to 05 months. 16/90 (17.77%) practitioners answered as 07 to 08 months. The Knowledge, Attitude and Practices of Medical Practitioners working in border districts of Kerala and Karnataka towards Standards of Tuberculosis Care was reasonably good. Even though patients belonged to separate states, notification of cases to Government of India through proper channel was good among the medical practitioners. Limitation of this study was smaller sample size and at two border district only.
Assessment of Flood Hazard Zonation Using Geographic Information System and Analytical Hierarchy Process: A Case Study of Tlawng River Watershed in Sairang, Mizoram, India

Flood occurs when the water inundates normally dry ground, which could happen in a variety of ways like excessive rainfall, overflowing of embankments, dams, rivers, snowmelt, and other factors. Floods are one form of a natural hazard which are difficult to contain and control. A flood susceptibility mapping using Geographic Information System (GIS) and Analytical Hierarchy Process (AHP) techniques were carried out at Sairang village in Aizawl, Mizoram in Northeast India. The study area Sairang is situated on the banks of the Tlawng river, the longest river in Mizoram. Floods have wreaked havoc in Sairang frequently resulting in huge losses and damage to property with numerous loss of life over the years. The total study area is 131.27 sq km and the resulting flood hazard potential zonation map shows that 1/3 of the watershed area falls in Vey High and High Potential Flood Hazard Zonation areas.

The approach is based on a novel modularised learning toolkit (both physical and virtual), which is described in this paper. The primary aim of this work is to arm universities, with the means to support the acquisition of these key skills by students in a motivating and effective way. A secondary aim is to support the wider effort of teaching computing in pre-university schools.
Yield and Water Use Efficiency of Sunflower as Affected by nano ZnO and Water Stress

Zinc has an important role in plants survival under environmental stress conditions. Nano technology can be used in crop production to increase yield. In order to evaluate sunflower responses to Zno nanoparticle, an experiment was conducted in Agricultural Research Center of Islamic Azad University, Birjand branch, Iran. The experimental design was a split plot based on randomized complete block with three replications. Two irrigation treatments (full irrigation and 50% water requirement) were as main plots and 7 ZnO fertilizer levels (control, three bulk ZnO treatments and three nano ZnO treatments) were as sub plot. Water stress reduced significantly seed and biomass yield. All ZnO application treatments increased significantly seed yield mainly through increasing seed number per head. Harvest index was not significantly affected by irrigation and ZnO treatments. Deficit irrigation significantly increased seed and biomass WUE 43.6 and 40.2 percent, respectively. In full irrigation treatment the highest seed and biomass WUE were related to bulk ZnO treatments, but in water stress condition the highest biomass WUE was related to NZnO treatment. Totally the result indicated that application of nano ZnO increased seed yield and water use efficiency.
