Performance and Detection of M-ary Frequency Shift Keying in Triple Layer Wireless Sensor Network

This paper proposes an innovative triple layer Wireless Sensor Network (WSN) system, which monitors M-ary events like temperature, pressure, humidity, etc. with the help of geographically distributed sensors. The sensors convey signals to the fusion centre using M-ary Frequency Shift Keying (MFSK)modulation scheme over independent Rayleigh fading channels. At the fusion centre, detection takes place with the help of Selection Combining (SC) diversity scheme, which assures a simple and economical receiver circuitry. With the aid of various simulations, the performance and efficacy of the system has been analyzed by varying modulation levels, number of local sensors and probability of correct detection by the sensors. The study endeavors to prove that triple layer WSN system is an economical and dependable system capable of correct detection of M-ary events by integrating frequency diversity together with antenna diversity.Comment: 13 pages; International Journal of Computer Networks & Communications (IJCNC) Vol.4, No.4, July 201

Dengue: experience from a tertiary care centre in Northern Karnataka, India

Background: Epidemiology of dengue infection is evolving, and research gap exists in the region. The clinical features, laboratory parameters, complications and treatment outcomes of patients diagnosed of dengue infection at a tertiary care centre were analysed in the present study.Methods: More than 12 years old patients, presenting with features suggestive of acute febrile illness were subjected to detailed history taking and thorough clinical examination. All the suspected cases were further evaluated with complete blood count, liver function test, kidney function test, along with ultrasonography of abdomen. Blood samples were tested for dengue antibodies (IgG and IgM) by hemagglutination inhibition method for confirmation of the diagnosis. The clinical course was closely monitored during hospital stay and complications and deaths, if any, were noted.Results: Total 140 patients were studied. Fever (100%), headache (80%) and myalgia (73.6%) were the commonest symptoms. Thrombocytopenia (136, 97.1%) was the commonest hematological finding, while severe thrombocytopenia (<50,000/cu. mm) was observed in 38 (27.1%) cases. Hepatomegaly (61, 43.6%), splenomegaly (42, 30.0%), ascites (54, 38.6%), pleural effusion and gall bladder edema (18, 12.9% each) were the commonest findings on ultrasonography. Shock and ARDS were the major complications.Conclusions: Dengue remains an important public health problem even at a tertiary care centre and strong suspicion is needed in adult patients with acute febrile illness. The management should focus on averting shock and ARDS, which would help in larger aim of reduction in mortality

Banana Peel as Removal Agent for Sulfide from Sulfur Springs Water

Banana peel which consider as fruit waste has been tested  for the removal of total sulfide from spring water in Heet area, Iraq. The chemical composition of peels was investigated. The results  show that the composition consists of  Sodium ,Potassium, Calcium ,Manganese and Phosphate and concentrations of these contents were 18.2mg/g, 62mg/g,15.4mg/g ,48mg/g and 0.37 mg/g , respectively. The alkalinity of peels was 5.2 mg/g and the moisture content was 5.8 % . The treatment efficiency was studied as a function of the retention time and  concentration of sulfide ion .The maximum sorption for sulfide was found to be 97% and it was nearly effective as activated carbon. As a result of the removal process , the concentrations of  some common anions ,cations and heavy metals (Mg+2,Ca+2,Na+,So4-2,cl-Po4-2, Cr, Fe, Ni, Cu and Zn) decreased ,the concentrations of K+ and Mn increased . Increasing of concentrations of K+ and Mn is attributed to their high content in the banana peels. A slight increase in pH of the treated water (6.5 – 7.5). This study revealed that  the treatment of water using the banana peel is most effective for removal of hydrogen sulfide from sulfur  spring water.

An Automatic Gastrointestinal Polyp Detection System in Video Endoscopy Using Fusion of Color Wavelet and Convolutional Neural Network Features

Gastrointestinal polyps are considered to be the precursors of cancer development in most of the cases. Therefore, early detection and removal of polyps can reduce the possibility of cancer. Video endoscopy is the most used diagnostic modality for gastrointestinal polyps. But, because it is an operator dependent procedure, several human factors can lead to misdetection of polyps. Computer aided polyp detection can reduce polyp miss detection rate and assists doctors in finding the most important regions to pay attention to. In this paper, an automatic system has been proposed as a support to gastrointestinal polyp detection. This system captures the video streams from endoscopic video and, in the output, it shows the identified polyps. Color wavelet (CW) features and convolutional neural network (CNN) features of video frames are extracted and combined together which are used to train a linear support vector machine (SVM). Evaluations on standard public databases show that the proposed system outperforms the state-of-the-art methods, gaining accuracy of 98.65%, sensitivity of 98.79%, and specificity of 98.52%

A Rare Penetrating Trauma of Both Orbit and Nasal Cavity

Introduction: Diagnosis of orbital foreign body (FB) penetration is usually obvious when part of the FB is still attached at the entry wound (1). However, the depth and course of the FB in this case was not visible.   Case Report: A 5-year old female presented with a pencil penetrating the left orbit. A computed tomography (CT) scan showed that the pencil penetrated the left orbit (extraseptal) through the lacrimal bone to the left nasal cavity, then perforated the nasal septum, crossing the right nasal cavity. Finally, the pencil penetrated the lamina paperatea to the right orbit and stopped near the right optic nerve. The pencil was gently removed under general anesthesia with close observation of the eyes.   Conclusion: A case of a pencil penetrating both orbits and nasal cavities was reported, and the pencil was safely removed. This draws attention to the possible penetration power of a pencil, with the possibility of injury to the orbit and optic nerve on the opposite side of the penetration. It also demonstrates the feasibility of safe removal

Laboratory approach for detection of non-invasive fungal rhinosinusitis: A case-control study

         Noninvasive fungal rhinosinustis is problematic being resistant to traditional medical treatment. Mycology laboratory work helps solving this issue. This case control study was designed to supplement the lacking information about the frequency of noninvasive fungal rhinosinusitis in our locality and identify fungal species responsible for this condition in Zagazig University Hospitals. In addition, to evaluate the role of microscopic examination, antigen detection and PCR in comparison to culture technique in diagnosis. Sinus material was collected from seventy eight cases represented clinically and radiologically with noninvasive fungal rhinosinusitis from June 2013 to September 2015. A control group 78 subjects with healthy sinuses from whom nasal smears were obtained. Samples were processed in Mycology Unit and examined microscopically in 10% KOH preparations. Lactophenol cotton blue slide preparations were examined for microscopic structures as hyphae and conidia. PCR amplification of the extracted DNA was performed using fungal universal primers for amplification of 28 S rDNA genes. Results: Microscopic examination revealed hyphae and fruiting bodies in 37 (47.4% of the cases). Culture diagnosed 36 FRS patients. Aspergillus fumigatus was the most frequently isolated from fungal rhino sinusitis (52.7 %) of cases, followed by Penicillium spp. in 22.2%. PCR amplification exhibits the same sensitivity and specificity as those demonstrated by microscopic examination (100% and 97.3% respectively). ELISA of Aspergillus galactomannan (GM) antigen lacked sensitivity (58.3%), with a higher specificity (100%). Conclusion: It is concluded that an experienced mycological confirmation especially, direct microscopic examination of clinically suspected noninvasive FRS cases is necessary for a final diagnosis. Key words: Rhinosinusitis; fungus; KOH; galactomannan; PCRRunning Title: Fungal rhinosinusitis mycology la

Sequence and structure based assessment of nonsynonymous SNPs in hypertrichosis universalis

Hairs are complex structures, making a protective layer and serves different biological functions. TRPS1, a transcription factor is one of the candidate genes causing congenital hypertrichosis, an excessive hair growth at inappropriate body parts. SNPs of TRPS1 were retrieved from dbSNP which were screened by SIFT and PolyPhen servers based on their functional impacts. Out of the screened SNPs, rs181507248 and rs146506752 were predicted as intolerant and damaging by both the servers. The predicted tertiary structure of the native TRPS1 after refinement and validation was successfully submitted to the Protein Model Database and was assigned with PMDB ID PM0077843, as it was previously unpredicted. It was observed through the structure based analysis that, the SNPs rs181507248 and rs146506752 caused significant changes in the secondary and tertiary structures as well as the physiochemical properties of TRPS1 protein. It can thus be concluded that the changed properties due to these single nucleotide polymorphisms effect the interactions of TRPS1 which result in congenital hypertrichosis

Patients and Methods We conducted a prospective study of National Health and Nutrition Examination Survey participants enrolled from January 1, 1999 to December 31, 2002 with BMI and ABI data available. ABI categories were 1.3 (high). BMI categories were <30 kg/m2 (nonobese) and ≥30 kg/m2 (obese). Cardiovascular (CV) and all-cause mortality were assessed by National Death Index records. Cox proportional-hazards models and Kaplan-Meier survival estimates were used to compare groups. Results In total, 4614 subjects were included, with mean age 56±12 years and BMI 28±6 kg/m2. Median follow-up was 10.3 years (interquartile range [IQR]: 9.3 to 11.4 years). Low and high ABI were present in 7% and 8%, respectively. After adjustment, low ABI was associated with increased all-cause and CV mortality in nonobese (hazard ratio [HR] 1.5, 95% CI, 1.1-2.1 for all-cause and 3.0 [1.8-5.1] for CV mortality) and obese individuals (1.8 [1.2-2.7] and 2.5 [1.2-5.6], respectively) compared with reference. High ABI was associated with increased CV mortality in nonobese (2.2 [1.1-4.5]) but not obese patients; it was not associated with all-cause mortality overall or when stratified by BMI. Conclusion In a US cohort, weight influenced the prognostic significance of high ABI. This may be related to technical factors reducing compressibility of the calf arteries in obese persons compared with those who are nonobese.The University of Kansas (KU) One University Open Access Author Fund sponsored jointly by the KU ProvostKU Vice Chancellor for Research & Graduate StudiesKUMC Vice Chancellor for Research and managed jointly by the Libraries at the Medical Center and KU - Lawrence.KUMC Vice Chancellor for Research and managed jointly by the Libraries at the Medical Center and KU - Lawrenc

Studies on Beneficiation of Manganese Ore through High Intensity Magnetic Separator

Upgradation techniques like wet sieving and magnetic separation were used to evaluate the beneficiation potential of manganese ore. During wet sieving, manganese content in raw ore was upgraded from 27% to a maximum value of 38% in the concentrate with a recovery of 30%. Size classification was found to have no measurable effect on manganese grade in magnetic separation. In the unsieved ground ore, manganese content of 45% was achieved with a recovery of 23% and Mn/Fe ratio of 19% at a magnetic intensity of 8500 Gauss. At the same operating conditions, SiO2 was reduced from 56% in the raw ore to 30% in the magnetic fraction. So, wet sieving technique leads to a comparatively lower manganese grade but better recovery. Conversely, a magnetic separation technique produced higher manganese grade but relatively lower recovery. Blending of the upgraded manganese ore with high grade iron ore can be done to achieve the required Mn/Fe ratio
