Assessment of Italian energy policy through the study of a photovoltaic investment on greenhouse

The production of energy from renewable sources is a form of energy production that has less impact on the environment than the traditional one. For the farmer this new form of production represents an opportunity, especially for the economic benefits that can produce, both in terms of the incentives provided by the public operator and for higher revenues, deriving from the energy sale and/or the saving generated by...

Development of a manually operated root crop washer

Root vegetables like carrot, raddish etc. need to be pre cleaned before transporting from field to market. At present there is no primary processing equipment like vegetable washers available for small farmers. A batch type, small vegetable washer with holding capacity 10 kg was developed for washing root vegetables like carrot and raddish. The washer consists of a detopper, a stainless steel washing drum, centre shaft...

Effect of ingestion of thermally oxidized sunflower oil on the fatty acid composition and histological alteration of rat liver and adipose tissue in development

The effect of ingestion of thermoxidized sunflower oil (TOS) on fatty acids composition and histological alteration was investigated in rats. The animals were divided into 2 groups, the first group fed on fresh sunflower oil (FSO) diet and a second group fed on TOS diet during 9 weeks. This oil was heated at 99 ± 2°C with incorporation of 9 L of oxygen/second during 52 h...

Prevalence of camel (Camelus dromedaries) mastitis in Jijiga Town, Ethiopia

A cross sectional study of camel mastitis was conducted on 384 lactating camels from Jijiga between November 2011 to April 2012 to estimate the prevalence and causes of mastitis, as well the risk factors involved on disease. Prevalence of mastitis was assessed by using California mastitis test (CMT). An overall prevalence of camel mastitis was found to be 30.2% (116/384) out of which, 4.9% (19/384), 25.3% (97) were...

Sheep and goats Cysticercus tenuicollis prevalence and associated risk factors

The purpose of this study was to estimate the prevalence of Cysticercus tenuicollis, identify factors that can influence its occurrence and to assess the distribution of the cyst in the visceral organs of sheep and goats slaughtered at Dire Dawa municipal abattoir. A total of 845 animals (425 sheep and 420 goats) were examined at the abattoir. The overall prevalence of C. tenuicollis was 24.6% (95% CI =...

Efficiency of motor-manual felling and horse logging in small-scale firewood production

The use of chainsaw tree felling in association with horse logging is quite common in harvesting operations, especially in the case of dense stands where thinning operations are applied. Many technical procedures can be applied in tree felling operations, depending mostly by the tree diameter. Also, timber logging may be done in one step by the means of horses when terrain’s slope is small. Based on a time study,...

Optimization of ethanol production from apple pomace through solid-state fermentation using enzymes and yeasts combination through response surface methodology

Apple pomace (AP) which accounts for 25% of original fruit mass is a by-product from the apple processing industry. Solid-state fermentation of AP was conducted on laboratory scale in 250 ml flask at 30°C, agitation speed of 55 rpm at different pH levels of 4, 4.5 and 5.0 using the Y51 strain, Saccharomyces cerevisiae (SC) ATCC 9673 and their combination. The sample was treated with both α-...

Molecular characterization of Pleurotus ostreatus commercial strains by random amplified polymorphic DNA (RAPD)

The genetic variability of strains of Pleurotus ostreatus expresses basidiomata with distinct morphological characteristics and responses of different production. Therefore, choosing the correct strain to be used is one of the factors limiting the cultivation of P. ostreatus. Thus, we evaluated the genetic variability (Random Amplified Polymorphic DNA (RAPD)), coloring pileus and yield, four commercial...

Studies on the chilling requirements of pecan nut (Carya illionensis Koch) cultivars

The chilling requirements of the male and female flower buds of 23 pecan nut cultivars were determined and compared for the tendency to protogeny/protandry during 2000 to 2004 winter periods by Weinberger’s standard and Richardson’s chill unit methods. Calculating the chilling hours below 7°C and chill unit (CU) values during the experimental winter periods, 555 to 660 h and 407 to 416 (CU) of chilling...

Bioaccumulation of heavy metal uptake by two different Vetiver grass (Vetiveria zizanioides and Vetiveria nemoralis) species

The efficiency of Cd, Pb and Zn uptake of upland vetiver grass (Vetiveria nemoralis) ecotypes as Kamphaeng Phet1, Prajuab Kirikhun, and Ratchaburi and lowland vetiver grass (Vetiveria zizanioides) ecotypes consisting of Kamphaeng Phet2, Mae Hongson, and Surat Thani were compared under sterile condition for interferent repudiation. The results showed that the total Cd accumulation of V. zizanioides was in the...

Standardization of germination media for the endangered medicinal tree, bael (Aegle marmelos)

Bael is an endangered medicinal tree, highly propagated through seeds. Either on trade or before sowing evaluation of seed germination is essential. International rules for seed testing recommended different techniques for seed quality evaluation. One such requirement is the selection of media for germination to assure actual germination as media provide proper platform for full expression of seedling emergence and...
