The Ti6Al4V alloy was difficult to cut material because of its inherent properties, however greater application in extremeoperating conditions; hence, the impact of machining parameters on nanoparticle diffused cutting fluids study was essential. The aim of this work was to examine the impact of alumina (Al2O3) nano-diffused cutting fluids under the minimal quantitylubrication (MQL) approach in the milling process on Ti6Al4V Alloy. Nano-based cutting fluid was prepared in unique weightpercentage concentrations of 0%, 1%, and 2% of nanoparticles with base fluid. The experiments were conducted to analysethe effect of spindle speed, cutting feed and axial cutting depth on the concentration of nanoparticles using the face-centredcomposite design (CCD) on cutting tool temperature (Ct) and surface roughness (Ra). The results revealed that Aluminananofluid minimizes the Cutting tool temperature and enhances the surface roughness (Ra). The responses were optimizedusing the desirability function based analysis (DFA) for nano based cutting fluids. The optimal process parameters of theAl2O3 nanofluid weight percentage concentration of nanoparticles were (2%), cutting feed (0.142 mm/rev), spindle speed(104 m/min) and DOC (0.5 mm).

<B>ABSTRACT</B><P>The detection of hundreds of thousands of new cases of leprosy every year suggests that transmission of <I>Mycobacterium leprae</I> infection still continues. Unfortunately, tools for identification of asymptomatic disease and/or early-stage <I>M. leprae</I> infection (likely sources of transmission) are lacking. The recent identification of <I>M. leprae</I>-unique genes has allowed the analysis of human T-cell responses to novel <I>M. leprae</I> antigens. Antigens with the most-promising diagnostic potential were tested for their ability to induce cytokine secretion by using peripheral blood mononuclear cells from leprosy patients and controls in five different areas where leprosy is endemic; 246 individuals from Brazil, Nepal, Bangladesh, Pakistan, and Ethiopia were analyzed for gamma interferon responses to five recombinant proteins (ML1989, ML1990, ML2283, ML2346, and ML2567) and 22 synthetic peptides. Of these, the <I>M. leprae</I>-unique protein ML1989 was the most frequently recognized and ML2283 the most specific for <I>M. leprae</I> infection/exposure, as only a limited number of tuberculosis patients responded to this antigen. However, all proteins were recognized by a significant number of controls in areas of endemicity. T-cell responses correlated with in vitro response to <I>M. leprae</I>, suggesting that healthy controls in areas where leprosy is endemic are exposed to <I>M. leprae</I>. Importantly, 50% of the healthy household contacts and 59% of the controls in areas of endemicity had no detectable immunoglobulin M antibodies to <I>M. leprae</I>-specific PGL-I but responded in T-cell assays to ≥1 <I>M. leprae</I> protein. T-cell responses specific for leprosy patients and healthy household contacts were observed for ML2283- and ML0126-derived peptides, indicating that <I>M. leprae</I> peptides hold potential as diagnostic tools. Future work should concentrate on the development of a sensitive and field-friendly assay and identification of additional peptides and proteins that can induce <I>M. leprae</I>-specific T-cell responses.</P>

<P><B>Abstract</B></P><P>We have measured the angular correlation of the pair nucleons <I>np</I> and <I>nn</I> emitted from the nonmesonic weak decay (NMWD) of <SUP>12</SUP><SUB><I>Λ</I></SUB>C produced via the (<SUP>π+</SUP>,<SUP>K+</SUP>) reaction in coincidence measurement. The Λp→np and Λn→nn modes were clearly identified by measuring the back-to-back correlation of the emitted nucleon pairs which is the characteristic of two-body kinematics. From the measured nucleon pair numbers <SUB>Nnn</SUB> and <SUB>Nnp</SUB>, the ratio <SUB>Γn</SUB>/<SUB>Γp</SUB> of the partial decay widths <SUB>Γn</SUB>(Λn→nn) and <SUB>Γp</SUB>(Λp→np) of <SUP>12</SUP><SUB><I>Λ</I></SUB>C was extracted to be 0.51±0.13(stat)±0.05(syst); this result is almost free from the ambiguity due to the nuclear final state interaction and 3-body decay process, which were inherent in the previous results. The obtained <SUB>Γn</SUB>/<SUB>Γp</SUB> ratio of <SUP>12</SUP><SUB><I>Λ</I></SUB>C (<I>p</I>-shell) is close to that of <SUP>5</SUP><SUB><I>Λ</I></SUB>He (<I>s</I>-shell). The results are consistent with those of recent theoretical calculations.</P>

Alam M.F.,Banu M.L.A.,Swaraz A.M.,Parvez S.,Hossain M.,Khalekuzzaman M.,Ahsan N. The Korean Society of Plant Biotechnology 2004 Plant molecular biology and biotechnology research Vol.6 No.4

Protocol was established for production of virus free healthy seeds using meristem ($0.3-0.5\;\cal{mm}$ in size) culture and field management under net house condition in tomato. The isolated meristem was found well established in MS liquid medium containing $0.1\;\cal{mg}\;1^{-1}\;of\;GA_3$. For shoot and root development either from primary meristem or from nodal segment of meristem derived plants, semisolid MS medium having $0.5\;\cal{mg}\;1^{-1}$ of IBA was found most effective. The elimination of the studied viruses (ToMV, CMV, ToLCV) in meristem-derived plants was confirmed by DAS-ELISA test. For field management of the virus eradicated meristem-derived plants, use of net house was found very effective measures to check viral vector visit and eventually infection. The meristem-derived plants were vigor and high yielder than the native seed derived plants and produced healthy seeds. Due to stop vector visit, no viral symptoms were observed in both $R_1\;and\;R_2$ plants cultivated in net house condition. Starting of viral infestation was observed in $R_2$ generation when they were planted in open house condition without control of vector visit. Therefore, for management of viral diseases, use of virus free meristem derived plantlets and their subsequent cultivation in soil under net house condition without using any vector killing insecticide can be recommended for producing healthy seeds in tomato. The developed protocol for environmentally healthy tomato seed production in Bangladesh may be used in the countries having similar tropical like environment conducive for viral vector visit.

Influence of Surface Effect On Nickel Micro Deep Drawing Process

In this paper, the forming behavior of nickel sheets is investigated as a function of the number of grains across the thickness by finite element simulations. Experimental tensile tests were carried out on nickel samples of approximately 100 μm grain size and thicknesses ranging between 12.5 μm and 3.2 mm. The decrease of the number of grains across the thickness involves a decrease of tensile stress due to the apparition of surface effects. These latter were taken into account for the deep drawing simulation of samples with 250 μm thickness by the use of two different constitutive elasto-plastic laws for surface and core grains. The simulations with two laws predict a modification of the distribution of the V.M. equivalent stress and of the damage zones compared to results from simulations using a simple average law.

<P><B>Abstract</B></P> <P>The present study highlights the options to enhance the methane potential of partially digested anaerobic sludge using disperser-induced bacterial disintegration. Floc dispersion with no biomass disintegration was achieved at a disperser-specific energy input of 9.5 kJ/kg TS. The outcomes of both sole bacterial disintegration (S-BD) and disperser-induced bacterial disintegration (D-BD) were assessed in terms of changes in lysate, biopolymer release and increase in biodegradability and methane generation. A higher lysate solubilization of about 22.4% was achieved in D-BD compared to S-BD (11.3%), indicating the efficiency of floc dispersion prior to bacterial disintegration. The biochemical methane result implies that D-BD shows higher methane potential of 0. 279 gCOD/gCOD. Considering the overall outcome achieved in this study, disperser-induced bacterial disintegration is proved to be an effective disintegration process for enhanced biodegradation and higher methane production.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Disintegration of digested sludge is a promising technique for bioenergy generation. </LI> <LI> Floc dispersion was achieved at lesser disperser input energy of 9.5 kJ/kg TS. </LI> <LI> A higher lysate solubilization of 22.4% was achieved in floc dispersed sample. </LI> <LI> Biopolymer release of floc dispersed sludge was higher (1379.8 and 394.2 mg/L) </LI> <LI> Result of methane reveals the effect of floc dispersion prior to disintegration. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Deep Spectral Time-Variant Feature Analytic Model for Cardiac Disease Prediction Using Soft Max Recurrent Neural Network in WSN-IoT

Cardiac disease analysis in big data is an emerging factor for human health protection against heart attacks. Most cardiovascular diseases lead to heart failure due to an imbalance of immunity and attention in health conditions. Hence, immunity-based feature analysis of patients’ records is essential to predict accurate results. The machine learning methods make predictions depending on the extended-lasting features to analyze the health data. But the marginal features expose non-relational feature observation to reduce the classifi cation prediction accuracy. We propose a Deep Spectral Time-Variant Feature Analytic Model (DSTV-FAM) using SoftMax Recurrent Neural Network (SMRNN) in a wireless sensor network to improve cardiac disease prediction accuracy. Initially, the IoT sensor devices collect the data from patient observation to validate the data transmission in route propagation. The collected data is organized as features in the collective dataset. The parts are initially preprocessed into the redundant dataset and estimate the Cardiac Immunity Infl uence Rate (CIIR) depending on the time-variant feature selection model. The estimated weights are marginalized as spectral features trained into the classifi ers. Further, Soft-Max Activation Function (SMAF) creates a logical function depending on the Cardiac Aff ection Rate (CAR). Then the trained, rational neurons are constructed into a Recurrent Neural Network (RNN) Feed-forward feature values using a classifi er and Rate of Disease Aff ection (RDA) by Class Type. The proposed structure yields high prescient exactness concerning order, accuracy, and review to help early treatment for early cardiovascular gamble expectation.

Dermatopathologic findings on cutaneous streptothricosis (bovine dermatophilosis) were conducted in Dinajpur of Bangladesh for one year. The animals were examined clinically at hospital during the physical visit of the affected animals and clinical manifestations and patients' history were recorded. The gross lesions were systematically examined, noted and categorized. An impression smear was made by the skin scraps, stained with Gram's stain and examined microscopically for the presence of causative bacteria. The suitable sizes of skins of 3 animals typically affected with dermatophilosis were collected surgically from the animals, and prepared for the histopathological study. The cardinal clinical features and gross lesions were characterized as paint-brush cutaneous surface with matted hairs, scab and crust formation, roughened coat; istopathologically as hyperkeratosis, parakeratosis, typical "palisading encrustations", extensive proliferation of coccoid shaped, bluish coloured bacteria (zoospores) in the cells of the outer rootsheath of the hair follicles, separation of keratinized layer from the epidermal epithelium, epidermal hyperplasia, densely cellular dermis with moderate destruction of glandular structures. Coccoid shaped gram positive organisms which form multidimensional arrangement were also observed by impression smear. The clinical signs, gross lesions, morphology of the organisms, staining properties, and histopathological features of the affected skin were diagnostic criteria for the bovine cutaneous streptothricosis.
