Highlights

Simulated Annealing (SA) algorithm is proposed for solving U-shaped line balancing problem (ULB). The objectives considered for the optimisation are to minimise the idle time of a U-shaped line and to minimise the workload deviation among workstations or a combination of both. Calculate the difference between the objective function values of the test solution and the current solution. This difference will be referred to as the energy change.

Highlights

The study was to assess the impact of Indira Sagar dam on floral resources in Eastern Ghats region of India, using a primary data base on floristic diversity. The dominant family was Euphorbiaceae with 15 species and Cassia was the largest genus. Several species may face more pressure from exploitation as they provide a number of useful products of the project area. Indira Sagar project is located at 170 25I 00IIN 810 63I 33IIE on river Godavari near Ramayyapet village of Polavaram Mandal of West Godavari district in Andhra Pradesh.

Highlights

Medical image processing is one the emerging fields in signal processing, where data to be processed extensively on large scales in order to diagnoses the patient illness. One of such an important applications are medical images mining, in which computational intelligence applied to automatically analyzing patient?s records aiming at the discovery of new knowledge potentially useful for medical decision making. The initial step is to remove the noise from the image, next step to segment the image with the proposed method, and finally extract various features such as area, perimeter, eccentricity etc. for further analysis.

Highlights

Weeds inventory survey and phytosociological studies have been conducted in the sugarcane fields of Visakhapatnam district, Andhra Pradesh during the period 2012 to 2013. The survey has been carried out at 100 randomly selected sugarcane fields and well explored covering all the geographical areas of Visakhapatnam district, to identify the weed flora, species composition, density, frequency and importance values index (IVI). A total of 88 plant species, belonging to 75 genera and 33 families were identified. Among the 33 families have been recorded, out of these 16 families are representing each species. Asteraceae is the largest family representing 10 species, Poaceae occupies the second position with 8 species followed by Amaranthaceae and Euphorbiaceae having 7 species each, Malvaceae 6, Acanthaceae and Convolvulaceae having 5 species each. The results of phytosociological studies revealed that the species are Cyperus rotundus (42%) Malvastrum coromandelianum (2.4) most abundant weeds.

Highlights

Worsening condition of our urban life such as uncontrolled growth of informal sector, destruction of the environment and abuse of ecological assets like water bodies and stretches of land have rendered cities in India in a regrettable state. A radical change in the development plan of open spaces in India can make it an eco-sensitive and a sustainable, urbanized center. A green space system is an essential ingredient of an urban ecosystem. Green space system planning and construction provides a crucial method for sustainable urban construction in India. Functions of an open space-turned-green space system essentially include protection, productivity, and recreation. This paper proposes sustainable urban green space system planning based on Geographic Information Systems, in order to provide experience for construction of sustainable cities in India. Combining ecological technology, water management systems, wastewater treatment technology and urban slow transport system people can utilize green space systems as an ecological, urban low carbon treatment facility as well as leisure and entertainment facility.

Highlights

Ethnobotanical surveys were conducted among the ethnic group of Bagata tribes inhabited in Paderu Division of Visakhapatnam District, Andhra Pradesh during 2013-2014. The informants are all of 50-60 years of age. A total of 30 plant taxa belonging to 20 families pertaining to 26 genera were reported. All the plant species need to be evaluated through phytochemical investigations to discover their potentiality as new drugs for better health. The present study reports a high degree novelty in the use, mode of administration of plants among the Bagata tribes reflecting the revival of interest in traditional medicine.

07. Evaluation of Colemanite against Wood-Destroying Insects.

Aparna Kalawate and K.Ch. Varadarajulu*

Graphical abstract

Highlights

Colemanite is hydrated calcium borate hydroxide and a borate mineral found in evaporate deposits of alkaline lacustrine environments. It is a secondary mineral that forms by alternation of borax and ulexite. As this chemical is less toxic to human beings and other organisms, it was chosen to assess its efficacy against various wood destroying insects. Colemanite at 1% concentration is the lethal dose found in the present investigation to make plywood free from wood destroying insects. In India, this is the first report where colemanite is used in the preservation of plywood.

08. Photoelectrochemical studies of nonstoichiometric nanostructured PbOx using Fe(CN)6−4/−3 as an active electrolyte in ionic liquid

Highlights

Photoactive nanostructured lead oxide was prepared by applying DC potential pulse in alkaline sodium sulfate solution at 800C. The resulting oxide thin film showed vertically aligned interconnected nanowall assemblies all over the active substrate. The film was characterized by XRD, SEM, EDX and UV-vis diffuse reflectance spectroscopy. The UV-vis measurements confirmed an optical band gap of 1.95 and 2.71 eV, which can be attributed to the phases respectively α-PbO and β-PbO. Photoelectro chemical measurements under chopped white light illumination condition in ionic liquid (BMIm Cl) medium showed a stable photoresponse extending to a wider potential range of 3.7 V compared to only 1.7 V in aqueous medium. Typical photocurrent densities of 3.01 and 4.03 mA/cm2 were obtained from ionic liquid and aqueous medium, respectively. The JV characteristic of a PEC cell indicates a low Voc of 273 mV in ionic liquid medium compared to 768 mV in aqueous medium. The low Voc is attributed to the shift of the redox potential of the active electrolyte in ionic liquid.

Highlights

On a global scale, people are demanding more attractive and tasty food. Both the quality of foodstuffs and aesthetic aspects contribute to the appearance of consumed meals. The attraction and appeal of individual dishes could be enhanced by edible flowers. Globalization has contributed not only to a better awareness of consumers but also to the comeback of earlier lifestyles, in which edible flowers played an important role. New information concerning the composition and nutritional value of edible flower is also important and represents a sufficient reason for their consumption. The aim of the article is to contribute popularization of edible flowers.

Highlights

In this paper, we investigate the effect of combined influence of Hall effect chemical reaction thermo diffusion and rotation on Hydro magnetic convective Heat & mass transfer flow of a micro polar fluid through a porous medium bounded by a semi-infinite porous plate in the presence of heat generating sources. The dimensionless grouping equations for this investigation on solved using small perturbation approximation. The effects of various dimensionless parameters entering to the problem on the velocity & temperature concentration micro rotation profiles across the boundary layer are investigated to graphs. Also the result of the couple stress coefficient, the rate of heat & mass transfer at the wall are evaluated for different variations of the parameters.
