The advent of very high speed shuttleless looms has increased the importance of sizing. Starch has been the most popular and
economic size material. Synthetic binders are also being blended with starch to improve weaving loom efficiency. Blending
may lead to give different properties, which can be suited for particular application. In the present study effect of blend
composition in modified starch and synthetic size blends have been evaluated and mechanical properties like cohesion power,
adhesion power, abrasion resistance, bending rigidity etc were studied. In general, it is being observed that paste characteristics
and film properties of polyester resin blends are better but because of economic reasons PVA and acrylic polymers are preferred.
In this study the effect of lubricant is also observed. It is analyzed that lubricant improves the various mechanical properties
and hence the weaving performance of the material. 相似文献

Gynoecious is an important economic trait of cucumber for determinant of earliness and yield, yet genetic mechanism is not well understood for this trait. The experiment was conducted using F2 mapping population by crossing of PPC-2, a gynoecious and parthenocarpic line with Pusa Uday (monoecious and non-parthenocarpic cultivar). Out of 179 SSR markers screened, 39 markers differentiated the gynoecious and monoecious parents. However, only 17 markers were segregating with F2 mapping population, those were used for genotyping and linkage map analysis and these markers were placed along with F locus on chromosome 6 covering a total distance of 100.4cM. The SSR markers, SSR13251 and UW020605 were found to be closely linked to gynoecious (F) locus at 1.0 and 4.5 cM, respectively. The segregation of F2 population of PPC-2 × Pusa Uday and GPC-1 × Punjab Naveen and test crosses for sex type herein suggested that single dominant gene controlled the gynoecious sex expression in cucumber particularly in gynoecious genotypes PPC-2 and GPC-1. Therefore, the monogenic dominant nature of gynoecious sex identified in the present experiment and SSR markers closely linked to the F locus will be useful in marker-assisted backcross breeding for transfering gynoecious trait into horticulturally desirable varieties. 相似文献

The study was conducted under the “Uttar Pradesh Sodic Lands Reclamation Project” to examine changes that occurred in the reclaimed sodic land in two districts of Uttar Pradesh, India. The study focuses on long‐term seasonal changes in the floral diversity and soil characteristics of the reclaimed sodic land over a period of 10 y. The changes in the floristic composition, plant density, and soil characteristics (microbial biomass carbon [MBC], pH, exchangeable‐sodium percentage (ESP), and electrical conductivity) were compared among the different study plots after different years of sodic‐land reclamation. The study plots comprised reclaimed land with rice–wheat cultivation; semireclaimed land under rice cultivation only and nonreclaimed barren sodic land. There was a significant variation in the floristic composition of the three study plots. Dominance in the floristic composition was shifted from monocotyledonous weeds in the nonreclaimed sodic land to dicotyledonous weeds in the reclaimed land after 10 y of reclamation. Among the soil characteristics, the most remarkable changes were observed in soil MBC and ESP during the course of sodic‐land reclamation. Soil MBC increased up to 480% and ESP values decreased up to 79% in the reclaimed plots with reference to the nonreclaimed plots. The soil amelioration was more pronounced in the upper layer (0–30 cm) as compared to the lower layer (below 30 cm depth). A positive significant correlation was revealed between soil MBC and floristic composition of the reclaimed plots. These changes in floristic composition and soil characteristics could be used as good indicators of the eco‐restoration of the sodic lands. The present study provides useful insights in understanding the temporal progress of eco‐restoration in the reclaimed sodic lands. 相似文献

The objective of the present study was to investigate the curative and antioxidative efficacy of ivermectin and ivermectin
+ vitamin E-selenium, and the influence of these agents on oxidative stress parameters in canines infested by Sarcoptes scabiei. Twenty two sarcoptic mites infested dogs and nine healthy dogs of 6 months to 2 years of age were divided into three groups.
Group I comprised of healthy dogs (n = 9) whereas animals in group II (n = 11) and III (n = 11) were positive for scabies. Group II animals were treated with only 1% ivermectin @ 0.2 mg/kg SC whereas group III were
additionally treated with Vitamin E and selenium (tocopherol 50 mg + Se 1.5 mg/ml) @0.5 ml/20 kg IM at weekly intervals for
three times. Blood samples were collected on day 0 and 28 post therapy. The values for hemato-biochemical parameters and activities
of antioxidant enzymes were significantly decreased (P < 0.05) whereas level of lipid peroxidation was significantly increased in all the infested dogs in comparison to the healthy
dogs on day 0 which approached normalcy by day 28 post therapy. The dogs of group III showed better clinical recovery in comparison
to group II at the end of therapy. Thus, administration of vitamin E and selenium in addition to standard therapy can alleviate
these alterations hastening the clinical recovery of diseased dogs and can be recommended as an adjunct therapy with miticides
for canine sarcoptic mange. 相似文献

Understory vegetation controls, in a significant way, the regeneration of overstory trees, carbon sequestration and nutrient retention in tropical forests. Development and organization of understory vegetation depend 3n climate, edaphic and biotic factors which are not well correlated with plant community structures. This study aimed to ~xplore the relationships between understory vegetation and abiotic factors in natural and planted forest ecosystems. A non-metric multidimensional scaling （NMS） ordination technique was applied to represent forest understory vegetation among five forest communities, i.e., a dry miscellaneous forest （DMF）, a sal mixed forest （SMF）, a teak plantation （TP）, a low-land miscellaneous forest （LMF） and a savanna area （SAV） of the Katerniaghat Wildlife Sanctuary, located in northern India. Microclimatic variables, such as photosynthetically active radiation （PAR）, air temperature （AT）, soil Lemperature （ST）, ambient atmospheric CO2 concentration, absolute air humidity （AH）, physical and chemical soil ~roperties as well as biological properties were measured. Understory species were assessed via 100 random quadrats （5 m x 5 m） in each of the five forests in which a total of 75 species were recorded encompassing 67 genera from 37 families, consisting of 32 shrubs and 43 plant saplings. DMF was the most dense forest with 34,068 understory individuals per ha of different species, whereas the lowest understory population （13,900 per ha） was observed in the savanna. Ordination and correlation revealed that microclimate factors are most important in their effect compared to ~daphic factors, on the development of understory vegetation in the various forest communities in the north of India. 相似文献

A nutrient budget was quantified for six polyculture ponds of giant freshwater prawn (Macrobrachium rosenbergii) and Indian major carps (Catla catla, Labeo rohita, and Cirrhinus mrigala). The initial stocking size of prawn postlarva was 16.50 ± 0.54 mm with a body weight of 0.05 ± 0.001 g. Body weight of major carps was 9.0 ± 0.89 g. The duration of culture was 280 days. Feed accounted for 82% of total nitrogen (N), 93% of total phosphorus (P), and 95% of organic carbon (OC) inputs. Harvest of prawn and carps recovered 44% N, 1% P, and 19% OC. N, P, and OC accumulated in sediment were 47%, 73%, and 69%, respectively. Nutrient load in the harvest water was 0.67 ± 0.21 kg inorganic N, 0.15 ± 0.01 kg P, and 7.72 ± 0.62 kg OC per ton of Indian major carps and prawn. 相似文献

The potential of alginate-coated chitosan microspheres to act as an antigen carrier through oral vaccination was explored in fish. Among different antigenic formulations such as antigen-loaded alginate-coated and alginate-uncoated chitosan microspheres, empty alginate-coated chitosan microspheres and free whole-cell antigen, only alginate-coated chitosan microspheres gave promising results for stimulating both adaptive and innate immune response up to 6 weeks of post-immunization. In addition, alginate-coated chitosan microspheres modulated antigen-release behavior, maintained structural integrity and stability and gave effective protection to antigens from acidic degradation in vitro for 12 h. However, none of these formulations tested in this study are effective for protecting fish against Aeromonas hydrophila infection under the conditions evaluated in the present work. The enhancement of the immune response observed with the antigen-loaded alginate-coated chitosan microspheres demonstrates its promising effect for oral antigen delivery in fish. 相似文献

Pathogenic variability of different isolates of Colletotrichum falcatum Went. collected from six varieties: Co 419, CoC 671 (from Andhra Pradesh), Co 86032, Co87044, 89V74, and a local variety in Bhadrak (from Orissa) were established. Six red rot isolates were differentiated into four distinct pathotypes, viz., pathotype A - Cf 419 and Cf Bdkh; pathotype B - Cf 671; pathotype C - Cf 89V74 and pathotype D - Cf 86032, and Cf 87044. Pathotype A showed a susceptible reaction to Khakai, CoC 671, CoJ 64, and Co 419. Also pathotype B showed a susceptible reaction to Baragua, CoC 671, Co 997, CoJ 64, Co 1148, and Co 975, whereas pathotype C showed a susceptible reaction to CoC 671, Co 7717, Co 997, CoJ 64, Co 975, and Co 419. But pathotype D showed a susceptible reaction to CoC 671 and Co 997. Polymerase chain reaction (PCR) amplification and subsequent restricted fragment length polymorphism (RFLP) analysis of internal transcribed spacer region of ribosomal DNA (rDNA) of Cf 89V74, Cf 671 and Cf Vittal (C. falcatum isolate from Vittal, Karnatak) by four restriction enzymes, Alu I, Msp I, Rsa I, and Pvu II revealed two distinct groups viz.Group 1- Cf 89V74 and Cf Vittal; Group 2-Cf 671. Restriction enzymes Alu I, Msp I, Rsa 1, and Pvu II produced fragment lengths of 380, 520, 550, and 580 bp for Cf Vittal and Cf 89V74, whereas fragment lengths of 420, 370, 440, and 460 bp were observed in Cf 671, respectively. The present investigation with the red rot infected sugarcane samples clearly indicated the existence of two pathotypes viz., pathotype A and pathotype B in Andhra Pradesh and three pathotypes viz., pathotype A, pathotype C, and pathotype D in Orissa. Pathotype C (Cf 89V74) showed similar ITS-RFLP pattern in Cf Vittal which was isolated from Karnataka. 相似文献
