Decision making tool called Decision Making Tool for Identification of Optimal Location in Aqua farming development was developed using Visual Basic programming language for identification of optimal location for aquaculture farming development. Twenty-four input criteria to the tool were categorized into six broad heads of main-criteria namely: water (10 sub-criteria), soil (5 sub-criteria), support (2 sub-criteria), infrastructure (3 sub-criteria), input (1 sub-criterion), and risk factor (3 sub-criteria). In this tool, the optimal location was identified based on the objective function, which was derived from the combination of rank sum, pair-wise comparison, and Technique for Order Preference by Similarity to the Ideal Solution methods. Based on the objective function values, alternatives (or aqua farms) were ranked in descending order in a table. In order to validate the developed tool, the same alternatives were ranked in descending order according to the observed average yield value per hectare (ha) for the last three crops. Spearman’s rank correlation was used to assess the correlation between ranks obtained by the tool and ranks obtained based on average yield. It showed with 99% confidence that a significant correlation exists between ranks obtained by the tool and ranks obtained based on average yield. Developed tool appeared to be confident and robust in proof-of-concept application for aquaculture farming development in Kalla mandal with reference to shrimp farms, West Godavari district, Andhra Pradesh, India. 相似文献

Polyploid breeding is an effective tool to induce variability in the existing population, specifically in the crops having very narrow genetic base such as acid lime. Hence, an experiment was conducted to induce polyploidy in acid lime through colchicine treatment. Higher frequency of triploids were obtained in 250 μM colchicine treatment (27.27%), whereas combination of 3× (21.42%), 4× (13.33%) and aneuploid (6.67%) were induced at 500 μM colchicine treatment. Measurement of stomatal density and guard cell size of colchiploids revealed that the former one has negative relation with ploidy level and a positive relation was observed between guard cell size and ploidy level. Further, area and size of nuclei also had a positive relation with ploidy level. Hence, stomatal density, guard cell and nuclei size can be used effectively as morphological marker for preliminary polyploid screening. From the experiment, it can be concluded that 500 μM colchicine treatment of in vitro derived shoot tip explants of acid lime is optimum for creating maximum possible variability through polyploidization in the existing acid lime population. 相似文献

Detection of the presence of Coxiella burnetii in a case of goat abortion: a first report from India
Rajagunalan S. Gururaj K. Lakshmikantan U. Murugan M. Ganesan A. Sundar A. Sureshkannan S. Andani Dimple Pawaiya Rajveer Singh 《Tropical animal health and production》2019,51(4):983-986
Abortion is a major cause of economic loss to the goat industry. Coxiella burnetii the causative agent of Q fever is an important zoonotic agent known to be prevalent worldwide. In the present investigation, we detected the presence of Coxiella burnetii by the modified Ziehl Neelsen method of staining and its DNA by trans-PCR assay in the placenta obtained from the aborted goat. We also ruled out other common causes of abortion in this case. Based on a literature survey, this is the first report on the direct detection of Coxiella burnetii from an aborted goat to be reported from India.

Maize is an important food and feed crop worldwide. Phytic acid (PA), in maize kernel, is an antinutritional factor. PA chelates mineral cations and causes mineral deficiency in humans and phosphorous deficiency in animals. The undigested PA excreted by monogastric animals causes phosphorous eutrophication. Therefore, development of low‐phytate maize is indispensable. The low‐phytate locus (lpa2 allele) has been transferred from low‐phytate mutant line ‘EC 659418’ into an elite inbred UMI 395 through marker‐assisted backcross breeding (MABB). The MABB involved three backcrosses followed by two selfing steps, including ‘foreground selection’, that is, selecting lines with lpa2 allele with the help of a codominant SSR marker ‘umc2230’ and ‘background selection’, that is, selecting plants having genetic background similar to that of the recurrent parent using 50 codominant SSR markers. Two low‐phytate lpa2 lines with genome similar (>90% similarity) to that of recurrent parent have been identified. These lines can be used as parent in future hybridization programmes for obtaining low‐phytate high‐yielding maize hybrids. 相似文献

Increasing demand for eco-friendly botanical piscicides and pesticides as replacements for harmful synthetic chemicals has led to investigation of new sources of plant materials. Stem bark of Terminalia arjuna, which has been used as a popular folk medicine since ancient time, was examined for its piscicidal activity. This study aims to determine toxicity of ethanol extract of T. arjuna bark on fresh water stinging catfish (Heteropneustes fossilis), along with evaluation of changes in hematological parameters of the fishes exposed to a lethal concentration. The percent mortality of fishes varied significantly in response to concentrations of the extract and exposure times (between exposure time F = 36.57, p < 0.001; between concentrations F = 39.93, p < 0.001). The lethal concentrations (LC50) of ethanol extract were found to be 12.7, 8.94, 5.63 and 4.71 mg/l for 24, 48, 72 and 96 h, respectively. During acute toxicity test, blood samples of treatment fishes showed significant decreases in the red blood cells count, hematocrit content, hemoglobin concentration, mean corpuscular hemoglobin concentration and plasma protein level when compared to those of the control group, while there were significant increases in the mean corpuscular volume, mean corpuscular hemoglobin, white blood cells count and plasma glucose concentration. These results suggest that T. arjuna bark extract could be considered as a potent piscicide due to its toxic effect on fish, particularly fish hematology. 相似文献

Short fragments from both complementary strands in the newly replicated DNA of bacteriophage SPP-1 总被引：3，自引：0，他引：3
Bacillus subtilis bacteriophage SPP-I has separable complementary DNA strands. Fragments of nascent DNA isolated a very short time after phage infection show that these short chains are complementary to both phage DNA strands, as observed by hybridization techniques. 相似文献

The work focuses on the influencing effect of fiber surface treatment by BP towards mechanical properties of BSF reinforced PLA composites. BSF were treated by BP to improve the adhesion between fibres and matrix. BSF (30 wt %) reinforced PLA (70 wt %) hybrid composites were fabricated by means of twin screw extrusion followed by injection molding process. Tensile strength, flexural strength and modulus were tested by means of UTM. The morphological analysis of the untreated and treated BSF reinforced PLA composites in comparison with virgin PLA was carried out by SEM to examine the existence of interfacial adhesion between BSF and PLA. The resultant data reveals that treated BSF restricts the motion of the PLA matrix due to better wettability and bonding. Consequently, mechanical properties like tensile and flexural moduli of BSF reinforced PLA composites were enhanced in comparison to virgin PLA and untreated BSF reinforced PLA composites. The results are discussed in detail. 相似文献

Analysis of 36 genotypes of finger millet ( Eleusine coracana (L.) Gaertn) with varying seed colors revealed a wide range of protein and calcium contents. White seeded genotypes had higher protein contents, while brown seeded types had a wide range of values. The brown seeded genotype GE 2500 had the highest protein content. Although protein content had significant negative association with calcium content, white seeded types had moderate levels of calcium. The genotypic coefficients of variability were moderate and high for protein and calcium, respectively. High heritability coupled with high genetic advance indicated their governance by additive gene action. A negative significant correlation was observed between protein content and grain yield. Mahalanobis D 2 analysis grouped the 36 genotypes into eight clusters. Clustering pattern failed to indicate any relationship between genetic diversity and geographic diversity. Based on genetic diversity and performance, the genotypes MS 1168, MS 174 and CO 13 were found to be suitable for use as parents in a hybridization program for improving yield; the genotypes MS 1168, MS 174 and MS 2869 for protein and Malawi 1915 and CO 11 for calcium. Protein and calcium contents contributed less to genetic divergence. 相似文献
