Abstract : The main objectives of this investigation was to study the effect of cow dung and poultry droppings on periphyton / biofilm development and growth performance of Nile Tilapia, Oreochromis niloticus, grown in inland saline water ponds provided with additional substrate. Two replicates per treatment were maintained. In the first treatment (T1) cow dung was used to fertilize the ponds, while in second treatment (T2) only poultry droppings and in the third treatment (T3) a combination poultry droppings and cow dung was used to fertilize the ponds. One way ANOVA revealed a significant (P<0.05) increase in mean fish weight, length, growth per day, SGR and condition factor (k) in poultry treated ponds (T2). Fish carcass composition also showed significantly (P<0.05) higher accumulation of protein, fat and phosphorous in fish grown in T2. DO concentration, nutrients (NO 3 -N and SO 4 ) and productivity indicating parameters remained significantly (p<0.05) higher, while BOD 5 and NH 4 -N remained significantly (P<0.05) lower in T2 in comparison with T1 and T3. Similarly, net primary productivity (NPP), gross primary productivity (GPP), chlorophyll a and epilithic chlorophyll a concentration were also significantly (P<0.05) higher, while water pheophytin a and epilithic pheophytin a remained significantly (P<0.05) lower in T2. The mean phytoplankton and zooplankton density was higher in poultry treated ponds (T2), followed by T1 and T3. A comparison of the periphyton density/biomass and its pigment concentrations indicated higher values for DM, AFDM, ash, ash % of dry matter, algal constitutes, autotrophic index, and total pigment concentration in ponds fertilized with poultry droppings (T2). Fertilizing the ponds with poultry droppings significantly P<0.05) reduced the inorganic N-species (NH 3 -N, and NO 2 -N) in the water column.
Key words : Periphyton, Nile tilapia, Growth, Brackish water, Organic manures

Abstract : Secure hash functions refer to key component of many applications, such as digital signature projects or authentication systems. Many of these applications are used in cost-sensitive markets and thus implementation of such component with low budget is very important. In 2012,the national institule of Technology (NIST), after a5-year long term competition selected keccak algorithm as a Hash function that must be standardized as SHA-3During and after this competition. Variety of keccak implementations have been proposed and evaluated for hardware platforms. However,few results were released for non -standard implementations, since to date SHA-3algorithm has not become operationl and presented only in few workshops, in this research firstly what is this algorithms and how it works are considered and then this algorithms is examined using software matlab.after examining software via quartus software, the program has been examined in hardware via verilog Ianguage and finally implemented on EP2C20F484C7N board and the results have been compared with the real value whieh has been presented via lexical.
Key words : keecak, SHA-3 algorithm , Software Review , Hardware Review , Implementation .

Abstract : This research was aimed at evaluation of bio-control effectiveness of Rhizopus spp. against Lantana camara initially Lantana Plants were treated by releasing insects Spilosoma oblique. Reported insect was able to develop, survive and reproduce vigorously on lantana plant parts under laboratory conditions continuously. Evidence of conspicuous and damaging effect of Rhizopus spp on lantana indicates that the pathogen is able to infect a wider range of weedy clusters and is significantly more damaging to target plant. Successful invasion has been obtained with the pathogen on already stunted weed infested with insect biocontrol agent which caused complete decay of the weed hence proved this fungi is highly host specific pathogen to lantana.
Key words: Biocontrol, Lantana camara, Spilosoma oblique, Rhizopus spp,.

The Effective Influence of Temperature on the Varied Characteristic of Silkworm: A Review

Abstract :The mulberry silkworm (Bombyx mori L.) is very delicate, highly sensitive to environmental fluctuations and unable to survive in extreme nature. The seasonal fluctuations affects the morphological as well as biochemical aspects of silkworm such as length & weight of larvae and diameter & weight of cocoon along with protein content of silk-gland and cocoon. The environmental conditions vary day to day and season to season highlight the requirement of physical parameters like temperature, light and humidity for sustainable cocoon production. The present review deals with the role of temperature on the growth and development of silkworm and its silk-gland. In this study CSR (multivoltine) and CV (bivoltine) hybrid is taken as raw materials. Bombyx mori L. CSR is a multivoltine crossbreed that produces high quantity of silk. The length and weight of worms and glands are directly related to the yield of silk, higher larval weights leads to higher production of silk. CV is also a thermo- tolerant bivoltine crossbreed that produces high quality of silk.
Key words: Bombyx mori, CSR hybrid, CV hybrid, bivoltine, multivoltine.

Abstract : The household milk consumers of India are mostly depend upon the supply of unprocessed bovine milk from unorganized street milk vendors that bypasses the quality control regime. Many factors affect the quality of traditionally collected milk, in which changes in environmental parameters is of utmost important. The aim of this study was to investigate the effect of different Ritus (Season) on the physico-chemical properties and microbial load of raw milk. About 600 raw milk samples were collected from the street milk vendors of the city of Jabalpur, throughout the year in order to cover all the six Ritus (Season) i.e. Shishira (late winter), Vasanta (spring), Greeshma (summer), Varsha (rain), Sharad (autumn) and Hemanta (early winter) and their physico-chemical properties including the Temperature, MBRT, Acidity, Fat (%age), CLR, SNF as well as microbial load (Coliform and Total count) were examined. The results showed that milk marketed during the spring (Vasanta) season; have good physico-chemical quality compared to all other seasons, and the parameters that tested for microbial quality of milk were reported best during the autumn (Sharad), shows the variations in the quality of the milk sampled might be attributed to the seasons.
Key words:Milk, Season, MBRT, CLR, SNF, Coliform and SPC.
