Expansion of an existing power system - a study

An existing paper mill is being expanded to increase its installed capacity. Concurrent expansions will be increasing the electrical demand by 40 - 50 MVA. The expansion also includes the addition of DC drives. The existing system has to be used effectively while additional equipment may be added to cater the load increase. Load flow study with various single line diagram configurations has been carried out to find the required solution. A harmonic analysis was also carried out on the suggested new system to install the required filters and capacitor blanks --Abstract, page ii

Does the phaco TIp position during clear corneal Phacoemulsification Surgery adversely affect corneal endothelium? TIPS study protocol for a randomised, triple-masked, parallel-group trial of bevel-up versus bevel-down phacoemulsification

Introduction: Globally, at least 30 million cataract surgeries are required annually to prevent cataract-related blindness. Corneal endothelial decompensation is one of the most common causes of poor visual outcome following cataract surgery, particularly in those with predisposing factors. The increasing ageing population and reduced visual impairment threshold for cataract surgery have resulted in rising cataract surgical rates and hence, an increase in corneal endothelial decompensation is expected. The role of phaco tip position on corneal endothelial damage is ambiguous. Previous studies have reported contradictory results and were also underpowered to detect a significant difference due to small sample sizes. With no consensus regarding the most cornea-friendly phaco tip position (bevel-up versus bevel-down) during phacoemulsification, we propose a randomised clinical trial with a robust design using direct chop phaco-technique. Objective: To compare the effect of phaco tip position (bevel-up vs. bevel-down) on corneal endothelial cell count during phacoemulsification. Methods: A randomised, multicentre, parallel-group, triple-masked (participant, outcome assessor, and statistician) trial with 1:1 allocation ratio is proposed. By adopting stratified randomisation (according to cataract grade), we will randomly allocate 480 patients aged >18 years with immature cataract into bevel-up and bevel-down groups at two centres. History of significant ocular trauma, previous intraocular surgery, shallow anterior chamber, low endothelial cell count, pseudoexfoliation syndrome, intraocular inflammation, and corneal endothelial dystrophy are the key exclusion criteria. The primary outcome is postoperative endothelial cell count at one month. Secondary outcomes are central corneal thickness on postoperative days 1, 15, and 30, and intraoperative complications.

The antiinflammatory potential of phenolic compounds from Emblica officinalis L. in rat

Antiinflammatory effects of phenolic compounds from Emblica officinalis were evaluated in carrageenan and cotton pellet induced acute and chronic inflammatory animal model. Fractions of E. officinalis containing free (FPEO) and bounded (BPEO) phenolic compounds were assessed by HPLC technique. The free and bound phenolic compounds were studied for their acute and chronic antiinflammatory activity at dose level of 20 and 40 mg/kg. The carrageenan induced acute inflammation was assessed by measuring rat paw volume at different time of intervals. Further, cotton pellet induced chronic inflammation was assessed by granulomatous tissue mass estimation along with the estimation of tissue biomarker changes (i.e. lipid peroxidation, reduced glutathione, myeloperoxidase and plasma extravasation). The results indicated that in both acute and chronic inflammation, FPEO and BPEO show reduction in the inflammation, but significant effects was observed only at high doses of both fractions which was comparable to diclofenac treated group. In conclusion, phenolic compounds of E. officinalis may serve as potential herbal candidate for amelioration of acute and chronic inflammation due to their modulatory action of free radicals

Synthesis and characterization of Sn‑doped TiO2 flm for antibacterial applications

Simple sol–gel method has been exploited to deposit Sn-doped TiO2 thin flms on glass substrates. The resultant coatings were characterized by X-ray difraction (XRD), UV–visible techniques (UV–Vis), Fourier transform infrared spectroscopy (FTIR), and photoluminescence analysis (PL). The XRD pattern reveals an increase in crystallite size of the prepared samples with the increasing doping concentration. A decrease in doping concentrating resulted in the decrease in bandgap values. The diferent chemical bonds on these flms were identifed from their FTIR spectra. The photoluminescence analysis shows an increase in the emission peak intensity with increasing dopant concentration, and this can be attributed to the efect created due to surface states. The prepared samples were tested as antibacterial agent toward both Gram-positive and Gram-negative bacteria like S.aureus (Staphylococcus aureus) and E.coli (Escherichia coli), respectively. The size of the inhibition zones indicates that the sample shows maximum inhibitory property toward E.coli when compared to S.aureus

Immunolocalization of Bcl-2 oncoprotein in amlodipine-induced gingival overgrowth

Background: Drug-induced gingival overgrowth (DIGO) is one of the unwanted side effects of amlodipine therapy, but the pathogenesis still remains unclear. Apoptosis, which plays a ubiquitous role in tissue homeostasis, including gingiva, may be involved in the development of gingival enlargement. Aims and Objectives: (i) To study the distribution of Bcl-2 in healthy and overgrown gingival tissues. (ii) To compare and correlate the Bcl-2 expression in gingival samples from subjects on amlodipine therapy to the findings in healthy controls. Materials and Methods: A total of 25 subjects were recruited for the study - 15 hypertensive patients and 10 systemically healthy subjects. Both the groups were analyzed for Bcl-2 expression using immunohistochemistry. Results: Few of the control specimens showed weak positivity to Bcl-2 antibody, with the distribution limited to the basal cell layers alone, whereas 10 hyperplastic specimens expressed Bcl-2 and, unlike the control group, the distribution pattern was seen in both basal and suprabasal layers. Conclusion: The results indicate that the pathogenesis of amlodipine-induced gingival overgrowth might involve inhibition of apoptosis, especially with morphogenesis of hyperplastic gingival epithelia

Analysis of Loader Arm of Pneumatic High speed Loader

The function of the loader arm of the high-speed pneumatic loader is to load the work piece from the conveyer belt into the die machine and vice-versa. The purpose of the work was to develop a Finite Element Model of the loader arm by using ANSYS Software. And with the help of the FEA model, the loader arm is optimized from stress and minimum deflection point of view. The knowledge of FEA and optimization is required to achieve the desired optimization in the existing structure.Polhemgatan 27A, LGH3 Karlskrona-37140 Mobile: +4673531914
