Background/Aims Cyclic vomiting syndrome (CVS) is a disabling migraine variant manifesting as severe episodes of nausea and vomiting and often refractory to many therapies. Gastric electrical stimulation (GES), which can reduce nausea and vomiting in gastroparesis, may provide symptomatic relief for drug-refractory CVS. This study assessed the utility GES in reducing the symptoms of CVS and improving the quality of life. Methods A one-year, non-randomized, clinical study was conducted. Eleven consecutive patients with drug refractory, cyclic vomiting syndrome based on Rome III criteria and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN), underwent treatment with temporary GES (Temp GES) and permanent GES (Perm GES). Post-treatment follow up was done up to one year after permanent gastric electrical stimulation therapy. Results Total symptom score decreased by 68% and 40% after temporary and permanent GES therapies, respectively. Hospital admission events significantly decreased to 1.50 (± 1.00) events from 9.14 (± 7.21) annual admissions prior to treatment with permanent GES. Vomiting episodes fell by 83% post Temp GES and 69% after Perm GES treatments. Mucosal electrogram values also changed after temporary stimulation. Conclusions In a small group of drug-refractory CVS patients, treatments with temporary and permanent GES significantly reduced the severity of gastrointestinal symptoms and frequency of hospital admissions.

Influence of Cutting Parameters on Tool Wear and Surface Roughness in Hard Turning of AISI H11 Tool Steel using Ceramic Tools

Sanjeev Saini,Inderpreet Singh Ahuja,Vishal S. Sharma 한국정밀공학회 2012 International Journal of Precision Engineering and Vol. No.

In machining of parts, surface quality is one of the most specified customer requirements. Major indication of surface quality on machined parts is surface roughness. There are various machining parameters which have an effect on the surface roughness, but these effects have not been adequately quantified. In order for manufacturers to maximize their gains from utilizing finish hard turning, accurate predictive models for surface roughness and tool wear must be constructed. This paper utilizes response surface methodology (RSM) for modeling to predict surface roughness and tool wear for variety of cutting conditions in finish hard turning. The experimental data obtained from performed experiments in finish turning of hardened AISI H-11 steel have been utilized. Decrease in feed rate and increase in cutting speed resulted in significant increase in surface quality. However, increase in cutting speed also produced relatively higher tool wear. Also depth of cut did not significantly affect the tool wear and surface roughness.

In this research work, we have focused on designing an energy efficient Sindhi Unicode reader based on LVCMOS for natural processing. Unicode is a standard for a universal character set for all the scripts of the world. It is one of the fundamental technological building blocks for exchanging textual information internationally, via computers. The scripts of Sindh are Brahmi-based writing systems. Our main aim of this paper is to build an energy efficient low power design for this we have taken different frequencies and calculated its power. We have done power analysis on a constant temperature that is 25 degree Celsius and also keeping air flow constant. We have varied frequency and calculated power for different LVCMOS IO STANDARDs. Our design is based on 28nm FPGA and the code has been tested on Kintex-7 and the device used is XC7K160T, package used is FBG676 and it is working on -3 speed grade. At the end we have concluded that there is 3.27%, 3.38%, 4.34%, 3.12%, 4.54%, 4.28% saving in power dissipation with LVCMOS18 and LVCMOS15 when compared with LVCMOS33 at 1400 MHz, 1.2 GHz, 2100 MHz, 1700 MHz, 1800MHz, 2.2 GHz respectively.

Bonamali Pal,Rupinder Kaur,Inderpreet Singh Grover 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.33 No.-

This article highlights comparative adsorption behavior and photocatalytic activity of TiO2nanostructures (P25, nanorods and nanotubes) for degradation of eriochrome black-T dye (EBT)depending on their structural morphology and metal ions (Fe3+ and Pt4+) deposition. Enhancement inadsorption capacity (qmax) was observed due to impartment of extra positive charges by Fe3+ and Pt4+impregnation and follow the order, Pt4+–P25–TiO2 (400 mg/mg) > Fe3+–P25–TiO2 (344 mg/mg) > P25–TiO2 (248 mg/mg) > nanotubes (123 mg/mg) > nanorods (69 mg/mg). The Fe3+ and Pt4+ loaded TiO2improved dye adsorption and degradation rate of EBT undergoing complete minerization to CO2 underUV light irradiation.

Radix mesiolingualis and radix distolingualis: a case report of a tooth with an unusual morphology

Gurudutt Nayak,Himanshu Aeran,Inderpreet Singh 대한치과보존학회 2016 Restorative Dentistry & Endodontics Vol.41 No.4

Variation in the root and canal morphology of the maxillary first molars is quite common. The most common configuration is 3 roots and 3 or 4 canals. Nonetheless, other possibilities still exist. The presence of an additional palatal root is rather uncommon and has been reported to have an incidence of 0.06 - 1.6% in varying populations studied. Whenever two palatal roots exist, one of them is the normal palatal root, the other is a supernumerary structure which can be located either mesiolingually (radix mesiolingualis) or distolingually (radix distolingualis). This case report describes successful endodontic treatment of a maxillary first molar with radix mesiolingualis and radix distolingualis. Identification of this variation was done through clinical examination along with the aid of multiangled radiographs, and an accurate assessment of this morphology was made with the help of a cone-beam computed tomography imaging. In addition to the literature review, this article also discusses the epidemiology, classifications, morphometric features, guidelines for diagnosis, and endodontic management of a maxillary first molar with extra-palatal root.

Simple and Mediator-Free Urea Sensing Based on Engineered Nanodiamonds with Polyaniline Nanofibers Synthesized in Situ

Kumar, Vanish,Mahajan, Rashmi,Kaur, Inderpreet,Kim, Ki-Hyun American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.20

<P>In an effort to develop a simple and mediator free sensing media for urea, a polyaniline (PANT) and graphitized nanodiamOnd (GND) nanocomposite was prepared at room temperature via an in situ interfacial polymerization approach. The interaction of ions produced during the hydrolysis of urea with nanomaterial was utilized for the amperometric sensing of urea. The performance of this composite (GND/PANI) was evaluated for the detection of urea referenced to PANI. Accordingly, both platforms exhibited good linearity across a varying concentration of 0.1 to 0.9 mg mL(-1) with limit of detection (LOD) values of 0.07 (PANT) and 0.05 mg mL(-1) (GNDs-PANI). As such, both of them were able to detect urea well below the common range in real samples. Moreover, their sensitivities were also determined as 140.5 and 381.5 mu A (mg mL(-1))(-1) cm(-2) with a response time of 15 and 20 s, respectively. As such, the incorporation of GND with PANT was helpful toward enhancement of sensitivity.</P>

Satvir Singh,B.S. Bajwa,Inderpreet Kaur 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.93 No.-

Uranium prevalence in water beyond WHO limit (30 mg/l) may pose potential chemical and radiologicaltoxicity which can cause severe health problems associated with kidney, brain, liver, heart, etc. Therefore,regular monitoring of uranium content and development of efficient remediation strategies for itsremoval from water resources has gained immense attention at global level. In the present work, zeoliticimidazolate frameworks (ZIFs) based on zinc (ZIF-8), cobalt (ZIF-67) and bimetallic zinc & cobalt (Zn,Co-ZIF) using 2-methylimidazole as organic linker, were developed following a rapid room temperaturesynthesis, characterised for their surface and functional features using X-ray diffraction, SEM-EDX, BETand FT-IR followed by their application as adsorbents for uranium extraction. ZIFs were found to performbest at optimum adsorption parameters: pH (5.0), adsorbent dose (0.4 g/l) and contact time (120 min). The maximum Langmuir adsorption capacity (mg/g) of three ZIFs follows the order as: ZIF-8 (781.0) > Zn,Co-ZIF (564.7) > ZIF-67 (409.1). Thermodynamic parameters confirmed the spontaneous and endother-mic nature of adsorption process. Three ZIFs exhibit high adsorption efficiency and regeneration abilitywere explored for their practical application as packing material in the columns used in water purifiersand found to serve as competent adsorbents for treatment of uranium contaminated groundwatersamples.
