Effect of Intensity on Prevalence of N3 Potential in Ears with Severe to Profound Hearing Loss

Objective of the study: To look for the presence of N3 potential at two different intensities in children and in adults. Method: A total of 260 ears with severe to profound hearing loss were studied from the participants in the age range of 1 to 50 years, with 170 subjects in the age group below 10 years and remaining 90 subjects of more than 10 years. Auditory brainstem response (ABR) was recorded at two intensities, 90 and 99dBnHL, to look for the presence of N3 potential. Result: N3 potential was observed in 30% of the total ears taken in the study at 90dBnHL and 38.8% at 99dBnHL. Presence of N3 potential in children was 45%, which was higher than the age group of above 10 years. When the intensity was increased there was an increase in amplitude and a reduction in latency with better wave morphology. Conclusion: It is better to use higher intensity for the identification of the N3 potential while doing ABR and thus with the single recording, auditory assessment as well as saccular assessment can be done

Serum cystatin C and serum creatinine levels in type 2 diabetes mellitus

Background: Diabetes mellitus is a metabolic disorder resulting from deficient insulin secretion, inefficient insulin action or both leading to chronic hyperglycemia. Diabetic complications result from the toxic effects of chronic hyperglycemia combined with other metabolic derangements. Diabetic nephropathy eventually leads to loss of kidney function, which is the most common cause of End stage renal disease. Measurement of GFR is an important parameter in assessing kidney function for which Creatinine is currently being used despite its inherent fallacies. Cystatin C is an alternative marker with some advantages. Aims and objectives: To measure the serum cystatin C levels in type 2 diabetes mellitus patients. To compare serum cystatin C levels with serum creatinine levels in type 2 diabetes mellitus patients.Methods: The study was carried out in 30 type-2 diabetic patients and 30 non-diabetic controls, in the age group of 35 to 75 years. Both the groups were age and gender matched. Serum cystatin C levels and serum creatinine levels were measured in both the groups. Serum creatinine was estimated by Jaffe's kinetic method, while the estimation of serum cystatin C was done by Immunoturbidimetric method.Results: Serum creatinine as well as serum cystatin C levels were significantly elevated in the study group as compared to non-diabetic controls. There was a strong positive correlation of serum cystatin C with serum creatinine.Conclusion: Serum cystatin C can be used as an alternative to serum creatinine in determining GFR in type 2 diabetes mellitus.

STEREOTACTIC BRAIN BIOPSY: A REVIEW OF 15 CASES WITH OUTCOMES

Objectives: Despite improvements in the imaging techniques which aid pre-operative diagnosis, starting specific treatment requires confirmation by histopathological examination (HPE). However dilemma arises in deep seated lesions, lesions in eloquent areas, and lesion in a patient with a poor performance score for palliation/adjuvant therapy. The aim of this study is to determine the diagnostic accuracy and benefits of stereotactic biopsy (STB) in cases of clinical dilemma plus its effect on post-operative stay, morbidity and mortality, and overall management of patients. Methods: In this study, a prospective analysis of 15 patients who underwent STB in our hospital from September 2019 to July 2020 was made. The histopathological data derived from the STB, its clinical benefits, and post-operative hospital stay were analyzed. Results: In terms of histopathology, glial tumor (66.7%) was the most common lesion. The success of obtaining positive STB samples in our study was 100%. Average post-operative stay was 3 days. The clinical benefits were immense as seen in the varied presentations and clinical dilemma with which the patients presented and a how a safely sourced tissue for histopathological diagnosis by STB greatly altered the treatment of the patient. Conclusion: STB is a multifaceted tool in clinical practice. It can be used in diagnostic and therapeutic situations. Furthermore, in recurrent high-grade cases, it aids in providing HPE diagnosis for a more logical adjuvant treatment than one that follows an assumed diagnosis based on image findings/undergo a high-risk interventional procedure to get a specimen. It is a relatively safe procedure

Design and Process control of Siemens polysilicon CVD reactor

The novelty in this paper is to develop a process control for the poly-silicon CVD reactor to achieve optimum productivity of Poly-silicon seed by controlling the process parameters. The production of ingot is done through Siemens process of decomposing Trichlorosilane by Chemical Vapor Deposition on slim tungsten rods. The hardware architecture proposed monitors and controls the systematic sequential stages furnishing dynamics of the plant at a high temperature around 1050°C-1100°C. The HMI communicates through NI's LabVIEW 8.6 package, alarming the user with Process mimic, Report generation, Data and Security management. The plant simulation is realized and verified with LabVIEW 8.6 Version and MATLab 7.5 software tools to obtain the effectiveness of proposed control technique. This GUI based SCADA handles likelihood of fault tolerance, ensuring risk controlled process with optimum productivity of poly-silicon by making system compliant to Industrial standards

Assessment of trace element accumulation in surface sediment of Sepang Besar river, Malaysia

Due to non-scientific industrial activity and urbanization, trace elements contamination has posed a threat to Malaysia's biodiversity-rich coastal wetlands, streams, estuaries, and mangroves. Commercialization has taken a toll on mangroves in backwater canals and along the banks of the Sepang River. As a result, a thorough examination of sediment quality from the Sepang River mangrove habitats is done with a focus on trace element pollution and pollution issues, taking into account the enormous ecological services that are offered to coastal communities and offering guidance for upcoming restoration efforts. The concentration of trace elements (Cr, As, Pb, Ni, Mo, Co, Cd, and Hg) in the sediment samples was measured using an induced plasma mass spectrometric (ICP-MS). Results of the study revealed that Arsenic (As) levels exceeded the Canadian range of low effects, indicating the possibility of deleterious biological consequences on mangrove plants and animals. In all sampling locations, the enrichment factor (EF) analysis revealed extraordinarily high enrichment of As (9.89–23.65) and Mo (4.74–12.03). The geo-accumulation index of As (1.83 – 3.04), Mo (1.40 – 2.74), and Cd (0.652 – 3.03) revealed that mangrove locations in the Sepang River have almost extreme pollution effects. Pearson's correlation, which deduced the anthropogenic influence of As, Cd, and Mo in mangroves, backed up this claim. Results of the study recommended that continue monitoring of pollutants released from anthropogenic sources is highly required and there is a strong need to take more stringent measures to protect the environment

Designing fuzzy rule based classifier using self-organizing feature map for analysis of multispectral satellite images

We propose a novel scheme for designing fuzzy rule based classifier. An SOFM based method is used for generating a set of prototypes which is used to generate a set of fuzzy rules. Each rule represents a region in the feature space that we call the context of the rule. The rules are tuned with respect to their context. We justified that the reasoning scheme may be different in different context leading to context sensitive inferencing. To realize context sensitive inferencing we used a softmin operator with a tunable parameter. The proposed scheme is tested on several multispectral satellite image data sets and the performance is found to be much better than the results reported in the literature.Comment: 23 pages, 7 figure

Detection of coupling misalignment by extended orbits

In this paper a ‘SpectraQuest’ demonstrator is used to introduce misalignment into a rotating machinery set-up. Depending on the coupling used in the set-up, angular and/or parallel misalignment can be brought in the rotating system. Traditionally, the data captured by accelerometers is transferred into the frequency domain in order to interpret the vibrations measured by the accelerometers. The frequency domain has proven its usefulness but even the time domain can come in handy to draw the right conclusions regarding to misalignment in a rotating set-up. Orbit plots display the integrated data captured by accelerometers, in order to display the movement of the rotating shaft. The influence of the misalignment and imbalance on these orbits will be discussed
