Effect of Various Nursery Media on Onion Seedlings Development
A field experiment was conducted to standardize the nursery raising technique for onion at the Horticulture Research Farm, Department of Horticulture, Allahabad Agricultural Institute-Deemed University, Allahabad, during 2005-2006. The treatments comprised combinations of soil, sand, FYM and vermicompost. Altogether, 14 treatments were applied in a randomized block design with three replications. Hundred percent germination was found with a combination of soil, sand and FYM in proportions of 2:1:2&2:2:1, and, 1:1:1&2:2:1 Soil:Sand:Vermicompost. Among all the treatments, the combination of soil 2 parts, sand 1 part and FYM 2 parts, significantly influenced growth and health of seedlings and produced the maximum seedling height (11.42 cm), stem diameter (0.33 cm), root length (10.86 cm), shoot fresh weight (6.96 g), root fresh weight (3.22 g), total seedling fresh weight (10.18 g), shoot dry weight (3.95 g), root dry weight (1.53 g) and total seedling dry weight (5.48g). Highest benefit:cost ratio of 3.72 was also seen in this treatment combination
Genetic analysis of agronomic and biochemical variables among different tomato (Solanum lycopersicum L.) accessions
In the present study, thirty accessions of tomato were evaluated for estimation of correlation and path analysis among various quantitative and qualitative characters related to fruit yield. There were highly significant differences among the accessions for all the characters studied as per the analysis of variance. Genotypic correlation coefficients were generally similar in nature and higher in magnitude than the corresponding phenotypic correlation coefficients. The results revealed that the fruit yield plant-1 was significantly and positively correlated with number of fruits plant-1 (0.3119 and 0.3184) followed by fruit set percentage (0.2434 and 0.2499), fruit weight (0.6766 and 0.6731), polar diameter of fruit (0.4687 and 0.4635) at genotypic and phenotypic level, respectively, indicating that effective improvement in fruit yield plant-1 through these characters could be achieved. Fruit weight showed positive and significant genotypic and phenotypic correlation with fruit yield plant-1 by having greatest positive direct effect (1.1298 and 1.1116) on fruit yield plant-1 at both levels, indicating the true relationship between them and the feasibility to exploit the potentiality of this trait for effective direct selection to improve fruit yield plant-1

Nonlinear modelling of sheep and goat populations in India
The objective of this paper was to study the trend in population of sheep and goat populations during 1951 to 2012 in India. The data were compiled from various issues of BAHS (Basic Animal Husbandry Statistics) for the period 1951 to 2012. Different nonlinear growth models such as Parabolic/Sikka, Brody, Brody modified, Wood, Logistic and Gompertz models were fitted to the census data of sheep and goat population. The goodness of fit of the models was tested by Coefficient of determination (R2), Adjusted coefficient of determination (R2), Mean Square Error (MSE), Mean Absolute Error (MAE) and Akaike Information Criteria (AIC). The populations of sheep and goat in India during the year 1951 were 39.10 million and 47.20 million numbers respectively and reached 135.17 million and 65.06 million respectively in the year 2012. Based on the various measures of goodness of fit we observed that the Parabolic/Sikka model was the best fitted model for studying the pattern in the populations of sheep and goat in India. This model has been used to project the sheep and goat population in India during 2020, 2025 and 2030. If the present pattern of growth continued in near future then the projected sheep population will be 102.37 million numbers whereas goat population will be 151.57 million numbers in the year 2030. The present study will provide the pattern in which the changes have been observed in sheep and goat populations in India during 1951 to 2012
Comparison of proximal femur locking compression plate with dynamic hip screw in management of inter-trochanteric fracture
Background: Intertrochanteric fractures are common in elderly population and pose a significant financial burden to the patients and family. Anatomically contoured proximal femur locking compression plate (PFLCP) is the latest addition to deal with these fractures, which creates an angular stable construct. It will theoretically lessen the risk of failure by screw cut-out and varus collapse, the common mode of DHS failure. Materials & Methods: This study was done to prospectively compare, the rate of union, complications, operative risks and functional outcomes in inter-trochanteric fractures treated with dynamic hip screw [DHS] and Proximal femur locking compression plate [PFLCP]. It also determined the effectiveness of PF-LCP in comparison to DHS in treatment of inter-trochanteric fractures. The data collected during the study of 30 cases of inter-trochanteric fractures, 15 cases were treated using PFLCP and other 15 group of cases were treated using DHS in the Department of Orthopaedics in Rajendra Institute of Medical Sciences, Ranchi from December 2012 to December 2014.Results: The functional outcome was measured with Harris Hip Score. In PFLCP group 7 (46.67%) cases had excellent result, 5 (33.33%) cases had good result, and 3 (20%) cases had fair result with no poor result. The mean score in PFLCP group was 86.4. In DHS group 7 (46.67%) cases had excellent result, 4 (26.67%) cases had good result, 2 (13.33%) cases had fair result and 2 (13.33%) cases had poor result. Conclusion: PFLCP is a good option for the management of inter-trochanteric fracture with high union rate and low rate of complication with high functional outcome and with a possibility that it can be done without C-Arm
Preparation and properties of electrodeposited Ni-TiO2 composite coating
The mechanical properties of cutting tools, such as microhardness, corrosion resistance, and coating adhesiveness, directly affect the tool life and indirectly affect the component cost. In this paper, Ni-TiO2 composite coating was prepared through electrocodeposition in order to improve the mechanical properties of tungsten carbide cutting tools. The microhardness of the Ni-TiO2 composite layer was studied by varying the input current density (mA cm-2), pH value of the electrolyte, and particle concentration of TiO2 in electrolyte bath. The microstructure and phase structure of the composite layer were investigated using atomic force microscopy , scanning electronic microscopy and X-ray diffraction. The surface morphology of the Ni-TiO2 coated layer shows fine-grained structures and higher microhardness at lower currents. The maximum microhardness of the coated layer, 1483 HV, is found at a current of 15 mA cm-2 and Watts solution pH of 4.5. It is observed that with the increase of TiO2 content, the microhardness of the coating also increases
Antigiardial activity of novel triazolyl-quinolone-based chalcone derivatives:when oxygen makes the difference
Giardiasis is a common diarrheal disease worldwide caused by the protozoan parasite
Giardia intestinalis. It is urgent to develop novel drugs to treat giardiasis, due to
increasing clinical resistance to the gold standard drug metronidazole (MTZ). New
potential antiparasitic compounds are usually tested for their killing efficacy against G.
intestinalis under anaerobic conditions, in which MTZ is maximally effective. On the
other hand, though commonly regarded as an âanaerobic pathogen,â G. intestinalis
is exposed to relatively high O2 levels in vivo, living attached to the mucosa of the
proximal small intestine. It is thus important to test the effect of O2 when searching
for novel potential antigiardial agents, as outlined in a previous study [Bahadur et al.
(2014) Antimicrob. Agents Chemother. 58, 543]. Here, 45 novel chalcone derivatives
with triazolyl-quinolone scaffold were synthesized, purified, and characterized by high
resolution mass spectrometry, 1H and 13C nuclear magnetic resonance and infrared
spectroscopy. Efficacy of the compounds against G. intestinalis trophozoites was tested
under both anaerobic and microaerobic conditions, and selectivity was assessed in a
counter-screen on human epithelial colorectal adenocarcinoma cells. MTZ was used as
a positive control in the assays. All the tested compounds proved to be more effective
against the parasite in the presence of O2, with the exception of MTZ that was less
effective. Under anaerobiosis eighteen compounds were found to be as effective as
MTZ or more (up to three to fourfold); the same compounds proved to be up to >100-
fold more effective than MTZ under microaerobic conditions. Four of them represent
potential candidates for the design of novel antigiardial drugs, being highly selective
against Giardia trophozoites. This study further underlines the importance of taking O2
into account when testing novel potential antigiardial compounds

Aldehydes: magnificent acyl equivalents for direct acylation
From the viewpoint of meeting the current green chemistry challenges in chemical synthesis, there is a need to disseminate how the cocktail of acylation and activation can play a pivotal role in affording bioactive acylated products comprising substituted ketone motifs in fewer reaction steps, with higher atom-economy and improved selectivity. In recent years, a significant number of articles employing the title compounds âaldehydesâ as magnificent acylation surrogates which are less toxic and widely applicable have been published. This review sheds light on the compounds use for selective acylation of arene, heteroarene and alkyl (sp3, sp2 and sp) CâH bonds by proficient utilization of the CâH activation strategy. Critical insights into selective acylation of diverse moieties for the synthesis of bioactive compounds are presented in this review that will enable academic and industrial researchers to understand the mechanistic aspects involved and fruitfully employ these strategies in designing novel molecules
Modelling of Rhode Island Red chicken strains
To study the growth pattern in body weight of 3 strains of Rhode Island Red chicken Bertalanffy, gompertz and logistic nonlinear models were fitted. From the data on body weights of three strains of Rhode Island Red, we observed that average body weights of male chicken were higher than the female chicken. Based on the various measures of goodness fit criteria we have observed that in modelling of body weight of the Rhode Island Red chicken Bertalanffy was the best fitted model. In case of Rhode Island Control, Bertalanffy was the best fitted model and for Rhode Island Control male chicken logistic was the best fitted model. In case of Rhode Island White chicken logistic was the best fitted model and in case of Rhode Island White male chicken Bertalanffy was the best fitted model. In case of female chicken of Rhode Island Red, Rhode Island Control and Rhode Island White strains gompertz model was the best fitted model. From these fitted models one can determine the expected average body weight of a group of birds of three strains of RIR chicken at any given age under normal conditions
