A Survey on Efficient Life Detection System Using Microwave Signal

Thousands of persons killed as a reason behind earthquake. The on top of words is not the headlines of the newspaper, however, such news come back once the disaster destroyed the sector. The disaster within the big apple town at ‘World Trade Center’ claimed lives of quite 5000 individuals. It absolutely was aforementioned if survivors have been found and rescue earlier the numbers of victims are lower. There is without stopping to the amount of lives lost because the results of such disasters as landslides, folded tunnels and avalanches. The microwave life detection system is developed for the search and rescue of victims at bay underneath the dust of folded building throughout the earthquake or different disasters. The projected system utilizes L-band frequency that is ready to notice metabolic process and heart fluctuations. The operation principle relies on physicist frequency shift of the radiation mirrored from the buried victim. The schematic diagram of microwave Transmitting/Receiving (T/R) and litter cancellation scheme square measure enclosed during this report. During this report varied components of a microwave life detection system like antenna, directional mechanical device, and splitter has been mentioned. By advent of this technique the planet death rate as a reason behind an earthquake might decrease to larger extent

Cribado de la actividad hipoglucémica in vitro de Murraya koenigii y Catharanthus roseu

Objective: The study aimed to verify the hypoglycemic effect of Murraya koenigii (M. koenigii) and Catharanthus roseus (C. roseus) by using various in-vitro techniques. Method: The extracts were studied for their effects on glucose adsorption capacity, in-vitro glucose diffusion, in-vitro amylolysis kinetics and glucose transport across the yeast cells. Results: It was observed that the extracts of M. koenigii and C. roseus adsorbed glucose and the adsorption of glucose increased remarkably with an increase in glucose concentration. There were no significant (p≤0.05) differences between their adsorption capacities. In the amylolysis kinetic experimental model the rate of glucose diffusion was found to be increased with time from 30 to 180 min and both the plant extracts exhibited significant inhibitory effects on the movement of glucose into external solution across the dialysis membrane as compared to control. The extracts also promoted glucose uptake by the yeast cells and the enhancement of glucose uptake was dependent on both the sample and glucose concentration. The extract of M. koenigii exhibited significantly higher (p≤0.05) activity than the extract of C. roseus at all concentrations used in the study. Our report suggests the mechanism(s) for the hypoglycemic effect of M. koenigii and C. roseus. Conclusion: The said effect was observed to be mediated by inhibiting alpha amylase, inhibiting glucose diffusion by adsorbing glucose and by increasing glucose transport across the cell membranes as revealed by in-vitro model of yeast cells. However, these effects need to be affirmed by using different in vivo models and clinical trials.Objetivo: El estudio tuvo como objetivo verificar el efecto hipoglucémico de Murraya koenigii (M. koenigii) y Catharanthus roseus (C. roseus) mediante el uso de diversas técnicas in vitro. Método: Los extractos se estudiaron por sus efectos sobre la capacidad de adsorción de glucosa, la difusión de glucosa in vitro, la cinética de amilolisis in vitro y el transporte de glucosa a través de las células de levadura. Resultados: se observó que los extractos de M. koenigii y C. roseus adsorbieron glucosa y la adsorción de glucosa aumentó notablemente con un aumento en la concentración de glucosa. No hubo diferencias significativas (p≤0.05) entre sus capacidades de adsorción. En el modelo experimental cinético de amilolisis, se encontró que la velocidad de difusión de glucosa aumentaba con el tiempo de 30 a 180 min y ambos extractos de planta exhibían efectos inhibitorios significativos sobre el movimiento de la glucosa hacia la solución externa a través de la membrana de diálisis en comparación con el control. Los extractos también promovieron la absorción de glucosa por las células de levadura y la mejora de la captación de glucosa dependió tanto de la muestra como de la concentración de glucosa. El extracto de M. koenigii exhibió una actividad significativamente mayor (p≤0.05) que el extracto de C. roseus en todas las concentraciones utilizadas en el estudio. Nuestro informe sugiere el mecanismo (s) para el efecto hipoglucemiante de M. koenigii y C. roseus. Conclusión: Se observó que dicho efecto estaba mediado por la inhibición de la alfa amilasa, la inhibición de la difusión de glucosa por la adsorción de glucosa y el aumento del transporte de glucosa a través de las membranas celulares según lo revelado por el modelo in vitro de células de levadura. Sin embargo, estos efectos deben ser afirmados mediante el uso de diferentes modelos in vivo y ensayos clínicos

Abstract: Special purpose machine are widely used for special kind of operations, which are not economical on conventional machines. It is design for getting higher accuracy at desired condition. Face milling in industrial component is followed by a milling process. In the initial core bore is develop on the component with the help of required tool material. A Special Purpose Machine introduced here can be operated manually or automatically, as per the condition or a mechatronic based system can be developed that will work with different speed. A SPM can be developing with two separate units which perform milling & boring operation sequentially. SPM introduced here is automatically start operation by sensing work piece on table; it helps in start & end of cycle. Milling Machine performs first milling operation of face of 105 x 135mm size and then boring machine for ø41.30H 7 × 20mm deep cylinder block. In this the job is machined on two machines and two fixtures are used and operation is performed, hence it takes 10 min. to completion of one job. In this method Bore to face perpendicularity not maintained, so accuracy is low. The production rate is very low due to time required for two times loading and unloading of job, operational accuracy required. The manpower is required is more & skilled. In order to successfully come up with these problems, company decided to develop Special Purpose Machine. It will save production time and increase the production rate

Detection of dengue-4 virus in pune, western india after an absence of 30 years - its association with two severe cases

<p>Abstract</p> <p>Background</p> <p>Difference in severity of dengue outbreaks has been related to virus serotype, genotype and clades within genotypes. Till the 1980 s, India and Sri Lanka reported low number of dengue hemorrhagic fever (DHF) cases despite circulation of all four serotypes of dengue virus (DENV). Since the 1990 s the occurrence of DHF has increased. The increase has been attributed to changes in virus lineage especially with regard to DENV-2 and DENV-3. DENV-1 has been associated with dengue fever (DF) outbreaks and DENV-4 reports have been rare. The emergence of DENV-4 was reported recently in 2003 in Delhi and in 2007 in Hyderabad. The last report of DENV-4 from Maharashtra was in 1975 from Amalner.</p> <p>Results</p> <p>We report on the detection of DENV-4 in Pune, Maharashtra after an absence of almost 30 years. Two cases were detected in 2009-10, serotyped by multiplex reverse transcriptase polymerase chain reaction (RT-PCR). Both the cases were recorded as severe dengue (Category 3) requiring intensive care unit (ICU) level of treatment. Depending on the hemagglutination inhibiting (HI) antibody titres the 2009 case was characterized as a primary infection and the 2010 case as a secondary infection. Both the cases presented plasma leakage and neither showed any kind of haemorrhage. The 2009 case survived while the 2010 case was fatal. An isolate was obtained from the 2009 case. Based on envelope (E) gene sequence analysis, the virus belonged to genotype I of DENV-4, and clustered with isolates from India and Sri Lanka and was distant from the isolates from Thailand. The nucleotide and amino acid diversity of the E gene of the Indian isolates increased from 1996 to 2007 to 2009 in context of the E gene sequences of other isolates belonging to genotype I.</p> <p>Conclusion</p> <p>The increasing diversity in the circulating DENV-4 calls for close monitoring of the DENV-4 serotype.</p

Diabetic foot complications among Indigenous peoples in Canada: A scoping review through the PROGRESS-PLUS equity lens

Introduction Indigenous peoples in Canada face a disproportionate burden of diabetes-related foot complications (DRFC), such as foot ulcers, lower extremity amputations (LEA), and peripheral arterial disease. This scoping review aimed to provide a comprehensive understanding of DRFC among First Nations, Métis, and Inuit peoples in Canada, incorporating an equity lens Methods A scoping review was conducted based on Arksey and O’Malley refined by the Joanna Briggs Institute. The PROGRESS-Plus framework was utilized to extract data and incorporate an equity lens. A critical appraisal was performed, and Indigenous stakeholders were consulted for feedback. We identified the incorporation of patient-oriented/centered research (POR). Results Of 5,323 records identified, 40 studies were included in the review. The majority of studies focused on First Nations (92%), while representation of the Inuit population was very limited populations (< 3% of studies). LEA was the most studied outcome (76%). Age, gender, ethnicity, and place of residence were the most commonly included variables. Patient-oriented/centered research was mainly included in recent studies (16%). The overall quality of the studies was average. Data synthesis showed a high burden of DRFC among Indigenous populations compared to non-Indigenous populations. Indigenous identity and rural/remote communities were associated with the worse outcomes, particularly major LEA. Discussion This study provides a comprehensive understanding of DRFC in Indigenous peoples in Canada of published studies in database. It not only incorporates an equity lens and patient-oriented/centered research but also demonstrates that we need to change our approach. More data is needed to fully understand the burden of DRFC among Indigenous peoples, particularly in the Northern region in Canada where no data are previously available. Western research methods are insufficient to understand the unique situation of Indigenous peoples and it is essential to promote culturally safe and quality healthcare. Conclusion Efforts have been made to manage DRFC, but continued attention and support are necessary to address this population’s needs and ensure equitable prevention, access and care that embraces their ways of knowing, being and acting

Obesity in total hip arthroplasty—does it really matter?: A meta-analysis

Discussion persists as to whether obesity negatively influences the outcome of hip arthroplasty. We performed a meta-analysis with the primary research question of whether obesity has a negative effect on short- and long-term outcome of total hip arthroplasty. We searched the literature and included studies comparing the outcome of hip arthroplasty in different weight groups. The methodology of the studies included was scored according to the Cochrane guidelines. We extracted and pooled the data. For continuous data, we calculated a weighted mean difference and for dichotomous variables we calculated a weighted odds ratio (OR). Heterogeneity was calculated using I(2) statistics. 15 studies were eligible for data extraction. In obese patients, dislocation of the hip (OR = 0.54, 95% CI: 0.38-0.75) (10 studies, n = 8,634), aseptic loosening (OR = 0.64, CI: 0.43-0.96) (6 studies, n = 5,137), infection (OR = 0.3, CI: 0.19-0.49) (10 studies, n = 7,500), and venous thromboembolism (OR = 0.56, CI: 0.32-0.98) (7 studies, n = 3,716) occurred more often. Concerning septic loosening and intraoperative fractures, no statistically significant differences were found, possibly due to low power. Subjective outcome measurements did not allow pooling because of high heterogeneity (I(2) = 68%). Obesity appears to have a negative influence on the outcome of total hip replacemen
