Published: April 2013

Abstract
The aim of this study was to acquire data on the physical properties and compression loading behaviour of seed of six corn hybrid varieties. The mean values of length, width, thickness, geometric diameter, surface area, porosity, single kernel mass, sphericity, bulk and true density, 1 000 kernelmass and coefficient of friction were studied at single level of corn seed moisture content. The calculated secant modulus of elasticity during compressive loading for dent corn was 0.995 times that of the semi-flint type; there were no significant differences in the value of this mechanical property between semi-flint and dent corn varieties. The linear model showed a decreasing tendency of secant modulus of elasticity for all hybrids as the moisture content of seeds increased.

Published: April 2013

Abstract
The aim of this research was to evaluate changes in soil quality associated with the tillage system applied with chosen parameters of soil biological properties. The long-term field experiments were located at a private farm in Rogów (Zamooeć region, E Poland) on a silt soil and at the Experimental Station in Laskowice (Wrocław region, S-W Poland) on a sandy loam soil. Soil samples were collected from 0-15 and 15-30 cm layers. Winter wheat was grown under traditional, reduced and no-tillage systems. The analyses included estimations of microbial biomass C and N content, microbial respiration rate, activity of dehydrogenase and arylsulfatase, and fluorescein diacetate hydrolysis. After eight years the effects of tillage on both soils were clearly noticed. In general, the less disturbing tillage systems enhanced the increase of soil biological activity by 15-40%, on average, than conventional tillage system. The significant correlations between microbial biomass, and/or enzyme activities with total organic C content indicate that concentration of organic C in soil environment plays an extremely important role in enhancing the stabilization and activity of soil microorganisms, and protection of an extracellular enzymes. The studied parameters of soil biological activity showed their sensitivity to tillage applied and may be considered as an useful indicators of soil quality in monitoring all conditions alter soil environment.

Published: April 2013

Abstract
The aim of the study was to determine the effect of different drying methods on selected physical properties of pomace obtained from purple carrot cv. Deep Purple. Drying was performed using four methods: convective, microwave-convective, infrared-convective and freeze-drying. The freeze-dried material had the lowest apparent density (422 kg m-3), which was caused by slight shrinkage, and indicated high porosity. Apparent density was almost three times greater in dried materials produced using the other drying methods as compared to the freeze-dried variants. Freeze-dried pomace adsorbed vapour more quickly than the other dried variants, which was caused by its high porosity and relatively low degree of structural damage. Rehydration characteristicswere significantly affected by the dryingmethod. The highest mass increase and losses of soluble substance were recorded for the freeze-dried samples. Conversely, the traditional convective drying method resulted in the lowest mass increase and soluble substance leaching. A positive linear correlation was found between the loss of soluble dry substance components and the absorbance of liquid obtained during rehydration.

Authors: Jezierska-Tys S. , Rutkowska A. 
Published: April 2013

Abstract
The effect of chemicals (Reglone 200 SL and Elastiq 550 EC) on soil microorganisms and their enzymatic activity was estimated. The study was conducted in a field experiment which was set up in the split-block design and comprised three treatments. Soil samples were taken six times, twice in each year of study. The results showed that the application of chemicals generally had no negative effect on the number of soil microorganisms. The application of Reglone 200 SL caused an increase of proteolytic and ureolytic activity and affected the activity of dehydrogenases, acid and alkaline phosphatases in the soil. The soil subjected of Elastiq 550 EC was characterized by lower activity of dehydrogenases, protease, urease and alkaline phosphatase.

Authors: Kougias P.G. , Fotidis I.A. , Zaganas I.D. , Kotsopoulos T.A. , Martzopoulos G.G. 
Published: April 2013

Abstract
Poultry manure is an ammonia-rich substrate that inhibits methanogenesis, causing severe problems to the anaerobic digestion process. In this study, the effect of different natural zeolite concentrations on the mesophilic anaerobic digestion of poultry waste inoculated with well-digested swine manure was investigated. A significant increase in methane production was observed in treatments where zeolite was added, compared to the treatment without zeolite.Methane production in the treatment with 10 g dm-3 of natural zeolite was found to be 109.75% higher compared to the treatment without zeolite addition. The results appear to be influenced by the addition of zeolite, which reduces ammonia toxicity in anaerobic digestion and by the ammonia-tolerant swine inoculum.
Electrical resistivity tomography to delineate greenhouse soil variability
Authors: Rossi R. , Amato M. , Bitella G. , Bochicchio R. 
Published: April 2013

Abstract
Appropriate management of soil spatial variability is an important tool for optimizing farming inputs, with the result of yield increase and reduction of the environmental impact in field crops. Under greenhouses, several factors such as non-uniform irrigation and localized soil compaction can severely affect yield and quality. Additionally, if soil spatial variability is not taken into account, yield deficiencies are often compensated by extra-volumes of crop inputs; as a result, over-irrigation and overfertilization in some parts of the field may occur. Technology for spatially sound management of greenhouse crops is therefore needed to increase yield and quality and to address sustainability. In this experiment, 2D-electrical resistivity tomography was used as an exploratory tool to characterize greenhouse soil variability and its relations to wild rocket yield. Soil resistivity well matched biomass variation (R2=0.70), and was linked to differences in soil bulk density (R2=0.90), and clay content (R2=0.77). Electrical resistivity tomography shows a great potential in horticulture where there is a growing demand of sustainability coupled with the necessity of stabilizing yield and product quality.

Published: April 2013

Abstract
The paper presents results of the scale-up silo flow investigation in based on accelerometer signal analysis and Wi-Fi transmission, performed in distributed laboratory environment. Prepared, by the authors, a set of 8 accelerometers allows to measure a three-dimensional acceleration vector. The accelerometers were located outside silo, on its perimeter. The accelerometers signal changes allowed to analyze dynamic behavior of solid (vibrations/pulsations) at silo wall during discharging process. These dynamic effects are caused by stick-slip friction between the wall and the granular material. Information about the material pulsations and vibrations is crucial for monitoring the interaction between silo construction and particle during flow. Additionally such spatial position of accelerometers sensor allowed to collect information about nonsymmetrical flow inside silo.

Published: April 2013

Abstract
With the increasing complexity and scale of industrial processes their visualization is becoming increasingly important. Especially popular are non-invasive methods, which do not interfere directly with the process. One of them is the 3D Electrical Capacitance Tomography. It possesses however a serious flaw - in order to obtain a fast and accurate visualization requires application of computationally intensive algorithms. Especially non-linear reconstruction using Finite Element Method is a multistage, complex numerical task, requiring many linear algebra transformations on very large data sets. Such process, using traditional CPUs can take, depending on the used meshes, up to several hours. Consequently it is necessary to develop new solutions utilizing GPGPU (General Purpose Computations on Graphics Processing Units) techniques to accelerate the reconstruction algorithm. With the developed hybrid parallel computing architecture, based on sparse matrices, it is possible to perform tomographic calculations much faster using GPU and CPU simultaneously, both with Nvidia CUDA and OpenCL.

Authors: Vazin F. 
Published: April 2013

Abstract
In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress and zinc spray on the yield and yield components of corn, an experiment was carried out during the crop seasons of 2010 and 2011 on Research Farm, Islamic Azad University of Gonabad as a split factorial within randomized complete block design with three replications. The main plots with irrigation factor and four levels were considered: A) full irrigation, B) stopping irrigation at pollination step, and C) stopping irrigation at the seed filling and four levels of zinc sulfate including 0 and 0.5%, 1% and 1.5% spraying (tassel initiation and grain filling) were as the subplots. The drought stress reduced the thousand kernels weight (TKW) in seed filling stage and the number of seeds per ear in tasseling stage about 11% and 27% less than the one of control treatment, respectively. Zinc increased the thousand kernels weight from 27.3 to 31.3 grams and induced an increase in the number of seeds per ear from 710 to 770. The results obtained within the present research showed that zinc spray has fairly improved the effects caused by drought stress.

Abstract
This study was performed to reveal the changes in cell division, as a result of the prolonged period of subculture on micropropagation medium, of five local varieties of Solanum tuberosum L. maintained on in vitro collection at Suceava Genebank, Romania. For this purpose it was used the Murashige-Skoog medium (MS- 1962) with addition of 40 g/l sucrose, and 6 mg/l daminozide. The effect of prolonged period of subculture up to two and 12 months was expressed as mitotic index and frequency of cells with abnormal division. Mitotic index ranged from 20.1 to 22.1% after 12 days, between 15.5 - 17.7% after two months and between 17.7 - 19.2% after 12 months of subculture. The results obtained showed that the frequency of aberrant cells increased with the preservation time on the in vitro cultures and their accumulation rate depended on the genotype. Were identified interphases with micronuclei, metaphases with retarded chromosomes, ana-telophases with chromosomal bridges, retarded chromosomes and chromosomal fragments, but their percentage was low in all the genotypes.

Abstract
A field experiment was conducted on sorghum (Sorghum bicolor (L.) Moench cv.) under three cutting system to determine the effect of nitrogen on growth and yield at University of Agriculture Faisalabad, Pakistan, during the season 2010-2011. The experiment was laid out in Randomized Complete Block Design (RCBD), using three replications. There were four levels of nitrogen 0, 50, 75 and 100 kg N/acre in the form of urea. The growth parameters like plant height, number of leaves, leaf area is determined periodically. First reading taken after 20 days of sowing while second and third was taken after 15 days of first cutting. Yield parameter like plant population, fresh and dry weight was determined in three cuttings. Results showed that increasing nitrogen dose increased all growth attributes. Results revealed for first, second and third cuttings showed significant differences at all growth attributes. Thus, the maximum plant height was observed in N4 (100 kg N/acre), having plant height 193.92, 195.24 and 192.79 cm in first, second and third cutting, respectively, which was followed by the treatment N3 (75 kg N/acre), having 179.70 cm in first cutting, while second and third cutting have same plant height 168.62 cm. The exception was the plant population showed non significant behavior in second and third cutting while number of leaves per plant in second cutting only and protein % in third cutting showed non significant difference with nitrogen application.

Published: April 2013

Abstract
Thermal regime of Cotnari vineyard, Iaşi County, Romania, was surveyed between 2011-2012 using 10 Tinytag temperature loggers TK-4014, spread in 10 different lands of the vineyard. Research is developed in the framework of the international project TERVICLIM (France), by means of was created a global network of analyses points of vineyard climate, spread in 13 countries from both hemispheres of the globe, at different latitudes. The data recorded by temperature loggers in Cotnari vineyard shows that in 2011-2012 winter, the minimum temperatures dropped to -28.6ºC, with differences of up to 7.1ºC between the coldest and the mildest lands of the vineyard. Spatial distribution of the most harmful frost (12 February 2012) shows that more than 80% from the vineyard area was exposed to temperatures lower than -24ºC, 17% to harmful temperatures between -21..- 24ºC and 3% to temperatures between -18..- 21ºC, less damaging to vines. As consequences, the damages in the vine plantations varied from less significant negative consequences for vines in the mildest location, up to massive losses of winter buds, damages of annual branches and frozen vines in the coldest land of the vineyard. Analytical data of winter buds losses spatial distribution shows that at - 28.6ºC (absolute minimum temperature for the vineyard), 0.46% (7.29 ha) of vine plantations were exposed to vines losses, 3.81% of plantations to losses of annual branches, 62.49% from vine plantations to winter buds losses exceeding 40%, difficult to compensate by pruning, 13.5% to losses of winter buds exceeding 60%, requiring reestablishing the vegetative potential of vines. The only vine plantations protected by harmful frosts were those located at over 175 m altitude, in the highest lands of the vineyards.
Immunosuppressive Action of Deoxynivalenol of Thymus in Chickens
Authors: Solcan Carmen , Cotea C. , Solcan Gh. 
Published: April 2013

Abstract
Deoxynivalenol (DON, vomitoxin) is a type B-trichothecene, naturally occurring contaminants of animal feed, being implicated in several mycotoxicoses in farm livestock. This mycotoxin occurs predominantly in grains such as wheat, barley, oats, rye, and maize, and less often in rice, sorghum, and triticale. Deoxynivalenol is potent nefrotoxic, hepatotoxic and immunosuppressant. High doses of trichothecenes promote rapid onset of leukocyte apoptosis (programmed cell death), which is manifested as immunosuppression. The study aimed to prove the immunosuppressant action of deoxynivalenol in chickens experimentally treated each day, from the 7th day of life, using 5,4 mg/kg b.w in E group for 28 days (since 35 days of life). Histopathology studies of thymus were made on 7th, 14th, 21st and 28th days of experiment. In E group small lesions of thymus were observed even after 7th day of poisoning but intense lesions, hydropic degeneration, necrotic foci and moderate lymphoid depletion was observed after the 14th and 21st day of poisoning. After 28th day a marked proliferation of stromal cells in the reticulum network, in medulla zone, presence of mucous cells, small mucous cysts and haemorages were observed.
