About the Cover

Evolutionary study is necessary to find out species’ relationship to other species. In this paper, rbcL gene sequences data are considered for analysis. It has fairly conservative rate of evolution. The function of the rbcL gene is to code for the large subunit of ribulose 1, 5 bisphosphate carboxylase/oxygenase (RUBISCO or RuBPCase). The sequence data of the rbcL gene are widely used in the reconstruction of phylogenies throughout the seed plants. Leguminosae family is one of the largest families that contain thousands of species of Plants, Herbs, Shrubs and Trees worldwide. Legumes are used as crops, forages and green manures; they also synthesize a wide range of natural products such as flavours, drugs, poisons and dyes. Legumes have the potential to play an increasing role in alleviating these threats owing to their ability to produce, with minimal environmental damage and external energy input in the form of nitrogenous and phosphorous fertilizers. In present studies group of plants were tested for their actual position based on various morphological characters and genomic information. This study shows plants belongs to Fabaceae (Papilionaceae), Mimosaceae, Caesalpiniaceae based on morphological characters has different members and the based on the genomic characteristics they fall in different groups. We conclude that as per botanical classification of species belonging to Leguminosae families are classified differently based on morphological character with compare to genomic characters.

DISCOVERY OF THE MONTH

Discovery of condensed milk in January 31, 1851

Brindha V

In 1851 Gail Borden announced his invention of condensed milk. He was a 19th-century U.S. inventor, surveyor, and publisher. He was born in Norwich, New York on 9 November 1801. He received the patent for his process of condensing milk by vacuum. Condensed milk is used in numerous dessert dishes in many countries. Gail Borden, process for condensing milk offered the first way to preserve milk without refrigeration, and improved the diet of nineteenth century Americans.

ANALYSIS

Quality assessment of cakes supplemented with cashew pomace and soybean flour

Akubor PI, Egbekun MK, Obiegbuna JE

The study investigated the quality of wheat flour (WF) cakes supplemented with cashew pomace (CPF) and soybean flour (SBF). The chemical and functional properties of WF, CPF and SBF were assessed. The CPF (30%) and SBF (70%) were blended to produce composite flour. The CPF/SBF composite was used to substitute 5, 10,15,20,25 and 30% WF in cakes which were assessed for their physical, sensory and chemical properties. The results showed that SBF contained higher amounts of ash, protein and fat than CPF and WF.

RESEARCH

Synthesis of 1,2-dihydro-6-(1H-imidazo(4,5-b) pyridin-2-yl)-4-aryl-2-oxopyridine-3-carbonitriles and 2-amino-6-(1H-imidazo (4,5-b) pyridin-2-yl)-4-aryl pyridine-3-carbonitriles

Dayakar G, Jeyanthi A, Ajay Kumar R

1(1H-imidazo[4,5-b]pyridin-2-yl) ethanol (3) is oxidized to form 1-(1H-imidazo[4,5-b]pyridin-2-yl) ethanone (4) by potassium dichromate. This is condensed with different aldehydes to form 1(1H-imidazo[4,5-b]pyridin-2-yl)-3-phenyl prop-2-en-1- ones 5(a-e),which is cyclised to get pyridine derivatives 6(a-e) and 7(a-e).

COMMUNICATION

Distributed operating system: a perspective

Annu, Himanshu Rehani

A distributed operating system is software over a collection of independent, networked, communicating, and physically separate computational nodes. Individual nodes each hold a specific software subset of the global aggregate operating system. Each subset is a composite of two distinct service provisioners. First is a ubiquitous minimal kernel, or microkernel, that directly controls that node’s hardware.

Tremor Suppression by Using Various Techniques

Shyam D Bawankar, Nitiket N Mhala

Physiological tremor is one of the main causes for human imprecision during micro surgery. The remote manually operated tasks such as those found in teleportation, virtual reality, or joystick based computer access, requires the generation of an intermediate electrical signal which is transmitted to the control subsystem. Tremor affects the human movement which can be improved by using various techniques.

Some Underutilised Plant Resources as a source of food from Ahmednagar District, Maharashtra, India

Mulay JR, Sharma PP

Traditional knowledge has assumed great importance in enhancing our knowledge about the plants which are used by the people since time immemorial. During last few decades, sufficient research work on ethnobotany has been done in various parts of India by several workers. However, Ahemednagar district have not been given enough attention as far as ethnobotanical studies are concerned. Hence, to fill up the gap present investigation has been undertaken.

Larvicidal activity of biologically synthesised silver nanoparticles against dengue vector Aedes Aegypti (Culicidae)

Ramar G, Suman T, Elangomathavan R, Jeyasankar A

Silver nanoaparticles have important applications in the field of biology. Stable silver nanoparticles were synthesized by biological reduction method. The objective of the present investigation was designed to determine the larvicidal activity of silver nanoparticles synthesized from aqueous leaf extract of Cleistanthus collinus against the larvae of Aedes aegypti .
