Incidence of post-harvest fungal rots of kinnow mandarin and their management
Indian Phytopathology , 2011,
Abstract: Various fruit rots caused by seven fungal pathogens isolated from diseased kinnow mandarin fruits during the entire marketing period from November to April next were green mold rot (Penicillium digitatum, P. italicum, P. chrysogenum), black mold rot (Aspergillus niger), core rot (Alternaria alternata), soft rot (Fusarium moniliforme) and stem-end rot (Botryodiplodia theobromae). The periods of fruit rot by fungal pathogens varied depending upon the prevailing temperature and humidity during their post-harvest journey in the marketing chain. The seasonal disease incidence of kinnow fruit clearly marked two distinct peaks of fungal rot spoilage. Out of a cumulative monthly fruit loss of 7.77-14.20% due to rot from November to April, the major fruit spoilage during this period was dominated by green and blue mold rots caused by P. digitatum (5.18-8.85%) and P. italicum (2.59-4.82%) with peak rot losses in January (8.25%)-February (8.85%) and February (4.82%)-March (4.43%), respectively. The second peak was dominated by green and black mold rots caused by P. chrysogenum and A. niger with a fruit spoilage of 3.67% by each pathogen during warmer month of April. The average monthly loss due to fruit rot during the entire marketing season was 11.61%. Postinoculation chemical treatments were ineffective against the major fruit rot pathogens. Pre-inoculation treatments of thiabendazole (0.05%), benlate (0.05%) and carbendazim (0.05%) were highly effective against green and blue mold rots caused by P. digitatum and P. italicum, respectively followed by salicylic acid (0.05%), sodium metabisulphite (0.5%) and borax (6%) whereas thiophanate methyl (0.25%) and borax (6%) were most effective against black mold rot caused by A. niger.
Packing systems and patterns of physical damage in post-harvest citrus fruit decay in Jammu markets
Indian Phytopathology , 2012,
Abstract: Mandarin oranges (Citrus reticulata) were packed and marketed in wooden boxes with paddy straw as cushioning material whereas kinnow mandarin and acid lime (Citrus aurantifolia) fruits were transported, bulk-packed in gunny bags, to the market. The nature of damage in mandarin was compression bruises and cuts on the fruits. Kinnow mandarin and lime had bruises due to rough handling, compression bruises due to over-filling and over stacking of bags, vibration bruises in transit and storage houses. Besides, Kinnow fruits had stalk puncture wounds. These injuries predisposed the fruits to fungal infections leading to fruit rots. Infections and cullage losses are, therefore, a direct consequence of rough handling and unhygienic storage conditions. A spectrum of post-harvest pathogens caused a variety of fruit rots viz., blue mold rot (Penicillium italicum), green mold rot (Penicillium digitatum, P. chrysogenum), Aspergillus flavus, A. fumigatus rots, black mold rot (Aspergillus niger), core rot (Alternaria alternata, Absidia corymbifera), soft rot (Fusarium moniliforme, Rhizophus stolonifer), stem-end rot (Botryodiplodia theobromae) and sour rot (Geotrichum candidum). Among other pathogens Penicillium spp. inflicted major fruit losses during winter months whereas Aspergillus spp. were responsible for sizeable losses during summer and monsoon months.
Prevalence of foliar blight pathogens attacking wheat in Shivalik foothills and significance of sowing dates for its management
Indian Phytopathology , 2011,
Abstract: Prevalence and distribution of wheat foliar blight pathogens in Shivalik foothill region of Jammu and Kashmir (India) and effect of sowing dates on disease severity were analyzed for four rabi seasons from 2001-02 to 2004-05. Helminthosporium sativum, Alternaria triticina, H. spicifer and Pyrenophora triticirepentis were isolated with an average frequency of 66.87, 23.65, 3.97 and 3.50 per cent, respectively and highest frequency of isolation was 72 (Rajouri), 26.5 (Jourian, Doda and Bhaderwah), 5.5 (Akhnoor) and 4.5 (Kathua and Katra), respectively. Setosphaeria halodes and Helminthosporium bico/or were occasionally found associated. Early sowing (October, 25) was found to be significantly most effective in reducing the disease severity which was 3.66, 3.66, 3.66 and 2.33 per cent with variety PBW 175 and November, 14 sowing recorded the maximum grain yields of 21.67, 22.05, 21.70 and 22.90 qha·1 having disease severity of 16.66, 18.33, 21.66 and 18.33 per cent with the variety PBW 299 in the crop season 2001-02, 2002-03, 2003-04, 2004- 05, respectively. Meteorological parameters significantly influenced the grain yield and disease incidence. The maximum pooled grain yields of 22.08, 20.01, 21.37, 22.10, and 18.98 qha' were recorded on November ,14 sown crop where meteorological parameters were optimum for the whole crop season and minimum pooled disease severity of 11.66, 12.49, 3.32, 5.91 and 24.58 was recorded on October, 25 sown crop where environmental condition for the growth of crop was optimum according to its different stages but unfavorable for the pathogen during the susceptible s

Revista Brasileira de Ensino de Física , 2011, DOI: 10.1590/S1806-11172011000100018
Abstract: i present a brief summary of the origins, applications and criticisms of the anthropic principle. i start with robert dicke's first arguments in favor of anthropic reasoning, continue through the formulations of brandon carter and the extrapolations of john barrow and frank tipler. in the end i analyse some of the most important consequences of the anthropic principle in cosmology and quantum mechanics. there is also a section dedicated to possible refutations of the anthropic principle.

The reliability calculation of foundations under eccentric load in the operation phase
V.S. Utkin
Magazine of Civil Engineering , 2013, DOI: 10.5862/mce.40.8
Abstract: The new method of the reliability calculation of buildings and structures’ earth foundations based on limited statistical information on controlled parameters in the operation stage is considered. The reliability is calculated by criterion of foundation deformations (settlement) in the presence of load eccentricity of the foundation and using possibility distribution functions for the description of fuzzy variables. New approach to the reliability calculation of a foundation bed is offered with describing eccentricity characteristic as random variable by the probability distribution law and properties of soil – by the possibility characteristic. The way for determination of eccentricity value of load on the foundation bed by measurement of deformations in the foundation material at the expense of unloading the part of the foundation on the area with resistance strain gages is considered. Reliability as the probability of failure-free operation of the foundation is characterized by the interval with minimum and maximum values.
Organization of pay for the production of a considerable number of heterogeneous operations
V.S. Medvedev
Marketing ì Mened?ment Innovacìj , 2011,
Abstract: The article presents approaches to the organization of labor in productions with a large number of dissimilar operations (eg, tool production). The major difficulty in assessing the results of such workers is the lack of standard, so measured and rated operations. There is shown the analysis of basic motivational factors of hourly and piece-rate pay systems for such productions. In the article there is developed the procedure for organizing the evaluation and pay system of workers according to individual productivity.
