Background/Aims: Gluten-free diet has an excess of fats and simple sugars and puts patients with celiac disease at risk of metabolic complications including metabolic syndrome and fatty liver. We assessed prevalence of metabolic syndrome and fatty liver in two cohorts of celiac disease. Methods: Study was done in 2 groups. In group 1, 54 treatment naïve patients with celiac disease were recruited. Of them, 44 returned after 1-year of gluten-free diet and were reassessed. In group 2, 130 celiac disease patients on gluten-free diet for ≥1 year were recruited. All patients were assessed for anthropometric and metabolic parameters and fatty liver. Metabolic syndrome was defined as per consensus definition for Asian Indians. Fatty liver was defined as controlled attenuation parameter value >263 decibels by FibroScan. Results: In group 1, of 44 treatment naïve patients with celiac disease, metabolic syndrome was present in 5 patients (11.4%) at baseline and 9 (18.2%) after 1 year of gluten-free diet. Patients having fatty liver increased from 6 patients (14.3%) at baseline to 13 (29.5%) after 1year of gluten-free diet (P=0.002). In group 2, of 130 patients with celiac disease on gluten-free diet for a median duration of 4 years, 30 out of 114 (26.3%) and 30 out of 130 patients (23%) had metabolic syndrome and fatty liver, respectively. Conclusions: Patients with celiac disease are at high risk of developing metabolic syndrome and fatty liver, which increases further with gluten-free diet. These patients should be assessed for nutritional and metabolic features and counseled about balanced diet and physical activity regularly. (Intest Res 2021;19:106-114)

Effect of Ba and Ho co-doping on crystal structure, phase transformation, magnetic properties and dielectric properties of BiFeO3

Jogender Singh, Ashish Agarwal,Ashish Agarwal,Sujata Sanghi,Tanvi Bhasin,Manisha Yadav,Umesh Bhakar,Ompal Singh 한국물리학회 2019 Current Applied Physics Vol.19 No.3

Multiferroics having composition Bi0.80-xBa0.20HoxFeO3 (BBFO, BBHFO5, BBHFO10, BBHFO15 and BBHFO20 for x=0.0, 0.05, 0.10, 0.15 and 0.20 respectively) were synthesized by method of solid state reaction. The crystal structure has been studied using X-ray diffraction technique. The X-ray patterns show enormous transform in crystal structure at concentration x=0.20. The Rietveld refinement of XRD patterns indicates that at concentration x=0.0 sample have rhombohedral structure with R3c space group while for the concentration x=0.05, 0.10, 0.15 and 0.20, the mixed phase including rhombohedral R3c and triclinic P1 space groups were obtained with best fitting. This phase transformation in crystal structure is observed due to mismatching of ionic radii of doped ions and parent ions. Magnetic properties of all samples were carried out by using vibrating sample magnetometry. M-H hysteresis loops shows that with doping of Ba and Ho antiferromagnetic BiFeO3 (BFO) transforms into ferromagnetic. The dielectric and ferroelectric measurements were carried out which shows that dielectric constant, dielectric loss and ferroelectric properties are enhanced with co-doping of Ho in comparison of the pristine BFO due to structure deformation and decrease in oxygen vacancies with higher concentration of Ho. Significant improvement has been observed in dielectric constant and remnant magnetization values with increasing content of Ho and decrease in the dielectric loss.

Numerical and Experimental Study on Effect of Different Types of Field-Shaper on Electromagnetic Terminal-Wire Crimping Process

Ashish K. Rajak,Ramesh Kumar,Hirak Basumatary,Sachin D. Kore 한국정밀공학회 2018 International Journal of Precision Engineering and Vol.19 No.3

Electromagnetic terminal-wire crimping (EMTWC) is a type of mechanical joining process. In EMTWC, the terminal is deformed over the wire strands plastically to enhance the mechanical strength by increasing the contact area. A well-crimped electrical interconnection helps to avoid harmful configurations by reducing sparks, overheating, power losses etc. Subsequently, the challenge to minimize various disadvantages of conventional mechanical terminal-wire crimping process like non-uniform deformation, decreased durability, cracks, etc., can be overcome by the electromagnetic crimping process. In this work, application of the fieldshaper has been proposed to concentrate the magnetic pressure at the desired location for effective wire crimping. Numerical analysis was carried out using LS-DYNATM on three different types of field-shaper namely single-step, double-step and tapered. In all the three field-shaper, the total length, the outer diameter and the effective working length were constant. The samples used was an aluminum terminal and seven strands of aluminum wires which are commercially used for making electrical inter connections. Experiments were carried out based on the results obtained through numerical analysis. Experimental and numerical results were in agreement and the error was less than 10%. The efficiency of single-step field-shaper was found to be better compared to double-step and tapered fieldshaper.

Carbon bead-supported copper-dispersed carbon nanofibers: An efficient catalyst for wet air oxidation of industrial wastewater in a recycle flow reactor

Ashish Yadav,Nishith Verma 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.67 No.-

Copper nanoparticle-doped and graphitic carbon nanofibers-covered porous carbon beads were used as an efficient catalyst for treating synthetic phenolic water by catalytic wet air oxidation (CWAO) in a packed bed reactor over 10–30 bar and 180–230 °C, with air and water flowing co-currently. A mathematical model based on reaction kinetics assuming degradation in both heterogeneous and homogeneous phases was developed to predict reduction in chemical oxygen demand (COD) under a continuous operation with recycle. The catalyst and process also showed complete COD reduction (>99%) without leaching of Cu against a high COD (∼120,000 mg/L) containing industrial wastewater.

Ashish Bansal,Ajay Kumar 대한수학회 2017 대한수학회보 Vol.54 No.1

We discuss the qualitative uncertainty principle for Gabor transform on certain classes of the locally compact groups, like abelian groups, $\R^n\times K$, $K \ltimes \R^n$ where $K$ is compact group. We shall also prove a weaker version of qualitative uncertainty principle for Gabor transform in case of compact groups.

Designing of Fuzzy Logic Controller for Liquid Level Controlling

Ashish Singh Thakur,Himmat Singh,Sulochana Wadhwani 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.6

In control system there are a number of general systems and methods which are encountered in all areas of industry and technology. There are many ways to control any system, in which fuzzy is often the very best way. The only reason is faster and cheaper. One of successful application that is used for the controlling of liquid level is fuzzy logic controller. In order to find the best design to stabilize the liquid level in this method, some factors will be considered. For this paper, the liquid level was controlled by using three rules of membership function which then extended to five rules, seven rules and nine rules for verification purpose and further improvement of the system. This paper was focused to the software part only. By doing some modification in this paper, the design will be very useful for the system relates to liquid level control that widely use in industry nowadays. For a long time, the selection and definition of the parameters of PID controller are very difficult. There must be a bad effect if you do not choose nicely parameters. To strictly limit the overshoot, the use of Fuzzy controller can achieve a great control cause. In this paper, we take the liquid level water tank, and use MATLAB to design a Fuzzy Controller. Then we analyze the control effect and compare it with the effect of PID controller. As a result of comparing, Fuzzy Logic Controller is superior to PID controller. Comparison of the control results from these two systems indicated that the Fuzzy logic controller significantly reduced overshoot and steady state error.

Ashish Raman,Soumya Prasanna Chattopadhyay,Ravi Ranjan,Naveen Kumar,Deepti Kakkar,Rajneesh Sharma 한국전기전자재료학회 2022 Transactions on Electrical and Electronic Material Vol.23 No.6

This paper presents a highly sensitive Recessed Gate/source/drain AlGaN/GaN HEMT (RG-AlGaN/GaN HEMT) based Carbon Monoxide gas sensors. Many types of Carbon Monoxide (CO) gas sensor have already been demonstrated experimentally. The deeply etched recessed gate based HEMT form highly sensitive 2DEG for small change in gate metal oxide. Copper Oxide and Cerium Oxide are used as a gate electrode in CO gas detection and these metal oxides are reactively sensitive to CO gas molecules. Because of the change in the work function of gate metal oxide due to the presence of gas deposition on it, there is the change in I off , I on , SS and V th which can be taken as sensitivity parameter for sensing the gas molecules. For a change in work function till 700meV using various steps sizes, RG-AlGaN/GaN HEMT based CO gas sensor shows highly sensitivity with respect to device characteristics parameters.

Ruthenium doped carbon aerogel with CO2 surface activation for enhanced electrochemical capacitance

Ashish Singh,D.K. Kohli,Sushmita Bhartiya,Rashmi Singh,M.K. Singh,P.K. Gupta 한국물리학회 2017 Current Applied Physics Vol.17 No.6

With the aim of enhancement of electrochemical capacitance, CO2 activation of carbon aerogel (CA) prepared by polycondensation of resorcinol with formaldehyde was performed to obtain activated carbon aerogel (ACA) having improved surface area properties. Ruthenium oxide nano-particles were loaded by impregnation method for utilizing pseudo-capacitive property of ruthenium oxide (RuO2) and the effect of activation treatment was studied. RuO2 loading of 20% by weight was accomplished in CA and ACA to synthesize RuO2 doped carbon aerogel (CA/RuO2) and activated carbon aerogel (ACA/RuO2). While the specific capacitance of carbon aerogel improved from 95 to 153 F/g on activation, RuO2 loading further led to enhancement in capacitance and specific capacitance of 308 F/g was obtained for ACA/ RuO2. The studies being important for Ru economy, showed the influence of surface area enhancement of base matrix in achieving high specific capacitance.

Backgrounds/Aims: A residual gallbladder (RGB) following a partial/subtotal cholecystectomy may cause symptoms that require its removal. We present our large study regarding the problem of a RGB over a 15 year period. Methods: This study involved a retrospective analysis of patients managed for symptomatic RGB from January 2000 to December 2015. Results: A RGB was observed in 93 patients, who had a median age of 45 (25-70) years, and were comprised of 69 (74.2%) females. The most common presentation was recurrence pain (n=64, 68.8%). Associated choledocholithiasis was present in 23 patients (24.7%). An ultrasonography (USG) failed to diagnose RGB calculi in 10 (11%) patients; whereas, magnetic resonance cholangio-pancreatography (MRCP) accurately diagnosed RGB calculi in all the cases except for 2 (4%) and, additionally, detected common bile duct (CBD) stones in 12 patients. Completion cholecystectomy was performed in all patients (open 45 [48.4%]; laparoscopic 48 [51.6%] and 19 [20.4%] patients required a conversion to open). The RGB pathology included stones in 90 (96.8%), Mirizzi’s syndrome in 10 (10.8%) and an internal fistula in 9 (9.7%) patients. Additional procedures included CBD exploration (n=6); Choledocho-duodenostomy (n=4) and Roux-en-Y hepatico-jejunostomy (n=3). The mortality and morbidity were nil and 11% (all wound infection), respectively. Two patients developed incisional hernia during follow up. The mean follow up duration was 23.1 months (3-108) in 65 patients and the outcome was excellent and good in 97% of the patients. Conclusions: Post-cholecystectomy recurrent biliary colic should raise suspicion of RGB. MRCP is a useful investigation for the diagnosis and assessment of any associated problems and provides a roadmap for surgery. Laparoscopic completion cholecystectomy is feasible, but is technically difficult and has a high conversion rate.
