Temperature is probably the most important environmental factor influencing the insect behaviour, distribution, development, survival and reproduction. Climate change, especially temperature increase, will affect insect physiology, behaviour, and development as well as species distribution and abundance, evidenced by changes in the number of generations a year, increasing survival rates in winter, and the earlier appearance of some insects. An investigation was taken up to understand the effect of different constant temperatures (28.3°C, 30.6°C, 32.7°C, 34.3°C and 36°C) on the egg hatching and development time of brown plant hopper (BPH). The results revealed that the temperature above 32.7°C was detrimental for the oviposoition by BPH females. Eggs hatching also decreased drastically with increase in temperatures. The development time taken by different stages of BPH varied significantly at different temperatures. Development time taken by different stages decreased considerably when the temperature increased. Longevity of the male and female adults also decreased with increasing temperature.Keywords

Background and purposeTo assess the effect of auditory feedback along with the conventional methods in improving the weight bearing symmetry of lower limbs and spatial temporal gait parameters in stroke patients.
Design
Non- randomized control trial.
Setting
Kasturba Hospital, Manipal and S.D.M. Ayurvedic Hospital, Udyavara, Karnataka.
Subjects
30 stroke patients (15 in experimental group and 15 in control group).
Interventions
Conventional weight bearing exercises was given for control group while the same was supplemented with auditory feedback device called "Ped Alert" for the experimental group. Exercises were given one hour per day, five days a week for two weeks.
Main measures
Weight bearing symmetry, spatial parameters (step and stride lengths), and temporal parameters (single and double limb support time, gait velocity, cadence, asymmetry ratio), of gait and Wisconsin Gait Scale (WGS).
Result
Within group comparison showed significant improvement in weight bearing symmetry, unaffected single limb support duration (SLSD), cadence, asymmetry ratio and WGS for the control group and significant improvement in velocity, cadence, affected step length, unaffected step length, affected stride length, unaffected stride length, WGS and weight bearing symmetry in the experimental group. Between groups comparison showed significant improvement in velocity (p=0.021), unaffected step length (p=0.013), unaffected stride length (p=0.048) and WGS (p=0.026).
Conclusion
Auditory feedback training has an additional role in improving unaffected step and stride lengths and gait velocity. However it may be as effective as conventional treatment in improving other spatial and temporal parameters of gait.

Computer-aided detection (CAD) systems are convenient for the automatic lung nodule detection in computed tomographic (CT) images, as the sheer volume of information present in CT datasets is overwhelming for radiologists to process. First, segmentation scheme is used as a preprocessing step for enhancement. Then, the nodule candidates are detected by Eigen value decomposition of hessian matrix and Multi-scale dot enhancement filtering. After the initial detection of nodule candidates using filtering technique, feature descriptors were extracted. The feature descriptor is refined using the process of wall detection and eradication. An Evolutionary Support Vector Machine (ESVM) is trained to classify nodules and non-nodules. The proposed CAD system is validated on Lung Image Database Consortium (LIDC) data. Experimental results show that the detection scheme achieves 98.3% sensitivity with only 11 false positives per scan.Keywords

Hastealloy C-276 is a difficult to machine superalloy and comprehensively employed in various engineering fields such as nuclear applications, aerospace and gas turbines. Hastealloy C-276 having better strength and poor thermal conductivity makes them difficult to machine materials which results in reduced life of the cutting tool and poor machinability by conventional methods of material removal. Advanced metal removal methods have evolved to accomplish those kind of needs and appealed to be an opposite alternative approach to traditional machining. Electro Discharge Machining (EDM) is considered as one of the nontraditional metal removal process which is especially adopted for machining of hard to machine materials. In this present investigation Spark Erosion Machining has been employed for machining of Haste Alloy C-276 with copper electrode by using Taguchi’s experimental design approach. Applied current (A), pulse on time (TON) and pulse off time (TOFF) were considered as the input process variables and the performance of spark erosion machining has been assessed by considering the performance measures such as material removal rate, surface roughness, overcut, form and orientation tolerance errors. The significance of process variables were analyzed by Analysis of Variance (ANOVA). Multi objective optimization has been performed by desirability function analysis to obtain better machining performance. In addition DFA based Adaptive Neuro Fuzzy Inference System (ANFIS) have been evolved to optimize the desired performance characteristics.Keywords

The machinability study on Wire Electro Discharge Machining (WEDM) of Al6061/20%SiC has been investigated in the present exploration. The objective of this present investigation is to determine the best possible process parameter to obtain better machining performance during wire EDM of Al6061 matrix reinforced with 20 wt. % SiC which is fabricated through the stir casting processes. The machining parameters such as pulse on time, pulse off time (delay time) and servo voltage are deemed as input process variables. Rate of material removal and roughness of the machined surface were considered as performance measures under this investigation. Taguchi’s design of experiment approach has been adopted for designing the experimental runs and L9 orthogonal array has been selected for conducting the experiments. Analysis of Variance (ANOVA) is adopted for ascertaining the significance of process parameters. Taguchi’s response analysis has been employed to determine the ascendancy of process parameters and the optimum process parameters were determined to obtain better machining performance.Keywords

Regional-level studies aimed at identifying and assessing various types of extreme weather events and comprehending their effects on various sectors are crucial. In the present study, we have utilized the RClimDex software to compute the trend in temperature and precipitation extreme events in the Varanasi district of Uttar Pradesh, India, from 1980 to 2018. We employed both Mann–Kendall test and linear regression to test the statistical significance of the computed trend. Out of 13 temperature indices, 8 showed a significant trend while the remaining showed a non-significant trend. The annual mean maximum temperature, warm days, diurnal temperature range and a monthly minimum of maximum temperature had decreased significantly by 0.029ºC, 0.159 days, 0.032ºC and 0.122ºC/yr respectively, whereas cool days and cold spell duration had increased significantly by 0.264ºC and 0.372 days/yr respectively, indicating an increased cooling effect over the study area. Similarly, out of the 11 rainfall indices, only two showed a significant trend, while the remaining showed a non-significant trend. The increasing drought over the study area is evident as the number of rainy days and consecutive wet days have decreased significantly by 0.262 days and 0.058 days/yr respectively, with a non-significant increase in consecutive dry days during the same period. The weak negative non-significant trend of a maximum of five consecutive days of rainfall, very heavy rainfall days and total annual precipitation indicate the decreasing trend of floods. This study stresses the development of adaptation plans to overcome the adverse consequences of extreme weather events in Varanasi district.Keywords
