Abstract
Comparing responses of the same soil under long-term different treatments is vital in determining the best management practices to conserve soil health and sustain productivity. This study was investigated to determine the effects of longterm (2006-2015) two conventional (CT), three reduced (RT) and a no-till (NT) treatment on bulk density (BD), field capacity (FC), wilting point (WP), available water content (AWC) and total porosity (TP) of a clayey soil in eastern Mediterranean region, Turkey. Undisturbed soil samples were collected from 0-10, 10-20 and 20-30 cm depths of experimental plots with a crop rotation of winter wheat (Triticum aestivum L.), soybean (Glycine max. L.), grain maize (Zea mays L.). The AWC under CT was higher than the RT and NT. The BD was increased with depth in all treatments, and was higher under RT and NT than the CT. The long-term experiment revealed that BD increase under long-term RT and NT should be monitored to avoid deterioration of soil health, and yield loss due to limiting root penetration and storing available water needed during drought periods.

Abstract
The present investigation aimed to understand the effects of dressing fertilizers and different nitrogen (N) doses on yield and nutrient uptake of chickpea (Cicer arietinum L.) plant. The study has been carried out with three repetitions under the greenhouse conditions. Nitrogen doses were; 0 kg N ha-1, 30 kg N ha-1, 60 kg N ha-1, 90 kg N ha-1 and 120 kg N ha-1 (in CaNO3.4H2O form) and dressing fertilizers were applied as 40 kg N ha-1. The results indicated that the dressing fertilizer application significantly increased average shoot dry weight with 8.18 g poƒ-1. Also, N (2.88 % N), P (0.40 % P), K (3.90 % K) and Fe (114.2 mg kg-1) concentrations increased with dressing fertilizer application of chickpea plant as compared to without dressing fertilizer application. However, dressing fertilizer application did not affect Mg, Zn, Mn and Cu concentrations of chickpea plant. Generally, in this study dressing fertilizer application increased yield and some macro and microelements concentrations of chickpea plant.

Published: September 2018

Abstract
The aim of the study was to assess the absorbtion degree of different nitrogen forms (ammonium, nitric, amidic) from soil into the plant by using nuclear techniques and 15N isotope as a tracer. In the same time, the effect of foliar fertilization on increasing the efficiency of nitrogen use by biostimulating the plant up-take was highlighted. Urea and ammonium nitrate labeled with 15N isotope (10% from total nitrogen content of the fertilizers being covered by 15N isotope) were incorporated in soil. In order to highlight the efficiency of foliar fertilization, fertilizers having NPK matrix with mezo and microelements and proteic organic compounds (animal and vegetal) were designed and obtained. The effects of experimental treatments on isotopic indicators (15N/14N isotopic rate, δ 15N isotopic accumulation degree, 15N isotope export, absorbtion degree of 15N isotope) from plant were assessed. The tested plant was maize (Cortes hybrid). The values obtained were statistically analyzed by using variance analyze, with two factors, Duncan test of multiple comparison, multiple comparison threshold α= 0.05. The results of agrochemical testing showed that the absorbtion degree of 15N isotope from soil into maize plant was highest for the amidic (N-NH2) form of the nitrogen comparing with the other forms (N-NO3, N-NH4).

Published: September 2018

Abstract
Wheat, being the main crop in Mediterranean type environments, is grown during winter under rainfed conditions and its yield potential is mostly affected by the amount and distribution of rain. This study is conducted at experimental fields of Ege University, Department of Field Crops in Izmir-Bornova which is characterized as Mediterranean type climate conditions during 2011/2012 and 2012/2013 growing season. Totally 9 canopy structures were generated by different row and line distances. Plant height, total dry weight, tiller number, harvest index, spike number, grain number per spike, thousand grain weight and grain yield were determined after harvest time while digital leaf area index and soil moisture contents were monitoring during specific growth periods to evaluate changes in soil water status by different canopy closer. Increasing in sowing density by different row and in-line distance reduced tiller and spike number per plant. On the other hand, grain number per spike and thousand grain weights were significantly affected by in-line distance instead of row distance. Higher grain yield were obtained from 20x1 cm treatments. Canopy cover speed determined using with digital imaging was not remarkable correlated (r=0.06) with soil moisture content during post-anthesis stage of wheat when higher rain amount is recorded in 2012. However, there was a significant negative correlation (r=0.51) between canopy cover speed and soil water status during post-anthesis stage when the rain amount is limited in 2013. We may suggest that rapid canopy cover lead to negative effect on soil water status via higher transpiration if the rain is limited during post-anthesis stage of wheat.

For all hybrids the same cultivation technology was applied. Sowing was carried out between April 20-27, for both years, with a density of 50,000 germinable grains/ha and in September were harvested. The analysis of the productivity elements showed that: the average length of cobs was between 20 to 23 cm; number of rows/cobs ranged from 14 to 18; the number of grains/cobs oscillated between 704 grains/cobs at Baragan hybrid, up to 890 grains/cobs at PR35T36; the Thousand Grain Weight (TGW) recorded values of over 300 grams for tree hybrids PR35T36, P0216, PR35P12; the density of plants at harvesting, main factor for yields grains, oscilated from 42,650 plants/ha in 2016 for Olt hybrid to 49.000 plants/ha at P0216 hybrid in 2017; the grains yields was of 8.4 t/ha at Baragan hybrid and 13.9 t/ha at PR35T36 hybrid. Regarding quality indicators of yields resulted: the hectolitre mass averaged 72.7 kg/hl with variation limits of 70.3 kg/hl and 76.8 kg/hl and the moisture varied between 11.90% and 14.50%. Chemical composition is followed: 10.70-12.70% proteins; 3.7-4.3% lipids; 70.00 - 70.70% glucids. Based on these results , it has been calculated the energy values (caloric). This oscillated between 369.3 kcal./100 grams of Rapsody hybrid and 388.38 kcal. of P0216 hybrid. It can be noticed that the year 2017 was a very favorable year for maize crops in the analyzed area, which led to better results for all the productivity elements, grains yields and chemical compozition for all 8 tested hybrids. Also, we can observed the higher energy value on 2017 by comparison with 2016.

Authors: Ţîţei Victor , Teleuță Alexandru 
Published: September 2018

AbstractThe family Malvaceae includes about 243 genera and at least 4 225 species of herbs, shrubs and trees. They are widely varied and include several important crops, which are mainly used as sources of fibre, food and beverages, medicines, timber. The species of the family Malvaceae: annual, Malva crispa and Malva meluca, native to East Asia, and perennial, Sida hermaphrodita, from North America, grown in monoculture in the experimental land of the Botanical Garden (Institute), served as subjects of the research, and the traditional crop Medicago sativa was used as control. The importance of the studied species of the family Malvaceae consists in their very rapid emergence and fast growth. The analysis of the chemical composition suggested that the dry matter of the studied species, at the 1stmowing contained 15.67-21.67 % raw protein, 2.15-4.46 % raw fats, 8.35-11.53 % minerals and 34.74-40.66 % nitrogen free extract, Medicago sativa - 17.03 %, 2.30 %, 33.31 %, 8.01 % and 39.41 % respectively, making them good candidates for use as livestock feed and for biomethane production. The nutritive value of 100 kg fresh mass of the studied Malvaceae species was 14.9-16.6 nutritive units and 153-173 MJ metabolizable energy, a nutritive unit contained 154.2-191.0 g digestible protein with high concentrations of limiting amino acids, the control - 21 nutritive units, 228 MJ and 164.3 g digestible protein, respectively. The calculated capacity of biomethane production of the studied Malvaceae species can reach 231-267 l/kg organic matter, Medicago sativa - 248 l/kg organic matter. The theoretical ethanol yield from structural carbohydrates of the dry biomass of stalks averaged 437-527 L/t in Malvaceae species, as compared to 485 L/t in corn. The best results were achieved by Sida hermaphrodita, due to its high amount of structural carbohydrates. These species may serve as feed for livestock, but also as multi-purpose feedstock for biorefinery in Moldova.

Abstract
The changes from Tax Code foresee that societies with fiscal value under one milion euro (to 500.000 euro till 31.12.2017) to be included in the micro-enterprises category and according to this provision owes to the state budget a 1% tax from fiscal value to 16% corporate tax. The paper presents benchmarking of this new fiscal measure applying above some retail and cash&cary societies from Romania to taxing profit in case this measure would be applied to all tipes of companies analysis based on a set of indicators (Absolute abnormality, growth index, turnover dynamics etc). The conclusions following the paper are: increase revenue collected to the state budget and simplifying the methods of determination to this tax but general apply to this measure could lead to infringement, encouraging layoffs, increasing unemployment, discouragement of investments, the impossibility of companies to recover in situations of crisis, discourage entry on market of new envestors, encouraging tax evasion, shortening economic chains.

Abstract
Paulownia ssp., in its places of origin, has been cultivated for over 2600 years and used as protection curtains against sand storms or floods, studies of how this species was exploited only fifty years ago in time what genetic research has only been affected in the last thirty years. The fundamental purpose of experimentation was to check the influence of different technological links (planting density and fertilization scheme), not only on the weight of the wood and the technological characteristics of the wood obtained, but also on the total biomass accumulation. The objectives of the research were: a) stems diameter increase, measured at 100 cm height from the soil surface, maintaining the harvest variant at 4 years; b) increasing of biomass accumulation. In all experimental variants, it is noted that the plants recorded higher values of the different variables analyzed (diameter at the base, normal diameter and total height), when the fertilization factor also intervenes. In the same way, when a higher fertilization was applied, higher values of the dendrometric indicators are obtained compared to the experimental variants that did not benefit from the supplementation of nutrients, suggesting that the most important risk factor in Paulownia plantations is the planting density and the fertilization element.

Published: September 2018

Abstract
The draught phenomena affecting the traditional agricultural areas in south of Romania has been increasing in intensity over the time, leading to the desertification of several thousands of hectares in the south part of the country. In this study we have computed the vegetation fraction cover for the South-West and South - East regions of Romania, based on the minimum and maximum NDVI extracted from MODIS satellite images. The time frame to refer to is 2000 - 2017, perennially, with special significance given the numerous and prolonged draught intervals these areas have been facing and the social economic evolution, from small farms to large agricultural holdings. The resulted vegetation fraction cover (fc) is correlated to the SPI values in order to determine a pattern to be used in anticipating deviations from the seasonal vegetation productivity. As a conclusion, the study presents a fair balance, indicating the most sensitive areas in soil vegetation cover, due to the SPI change.

Published: September 2018

Abstract
The lungworm Aelurostrongylus abstrusus (Nematoda: Angiostrongylidae) is a parasite of domestic and wild felids with worldwide distribution. The parasite lives in bronchioles and alveolar ducts, and its presence is associated with respiratory clinical signs. Cat lungworms are still considered by many clinicians sporadic and rarely are taken into account in the cat pathology. Therefore, in this paper we present a clinical and epidemiological study on cats with natural A. abstrusus infection. For this, 131 cats, with exclusive outdoor or outdoor and indoor access, of different gender (49 males, 82 females) and age (between 2 months and 11 years), from Southern and Center Romania, were included in the study. Of them, individual fresh faecal samples were collected and analyzed to identify first-stage larvae (L1) of lungworms, using a Baermann technique, and eggs/oocysts of other endoparasites, by a flotation method. Subsequently, of the examined samples, 6.10% (8/131) were positive for A. abstrusus. The positive cats aged between 3 months and 2 years. Of them, 3 cats were co-infected: two with Toxocara cati and one with Ancylostoma tubaeforme. Clinically, 75% (6/8) of the infected cats displayed respiratory signs varying from mild (sporadic coughing, sneezing) (n=3) to severe symptoms (mucopurulent nasal discharge, abdominal breathing) (n=3), while 25% (2/8) showed no respiratory signs. The three cats with severe respiratory disease were infected only with A.abstrusus. In conclusion, veterinary practitioners should include Aelurostrongylus infection in the differential diagnosis of catʼs respiratory pathology.

Abstract
The aim of this paper was to present a histological evaluation of the treatment performed on a humanmodel of osteomyelitis induced in rabbits. Osteomyelitis was induced in rabbits by a human strain of Staphylococcus aureus injected in bone defects created in the rabbit tibia. There have been created five groups of animals, groups receiving treatment in two different stages of the disease, acute and chronic. Copper and silver sub-millimetre-particles were introduced in the same place with the Staphylococcus solution. Evaluation of installation and evolution of the disease was done by clinical, hematological, microbiological, radiological and histological monitoring. A separate study of histological data is presented here. Histological examinations performed by HE was done on 5 μm sections of uncalcified bone. Every examination was classified according to a system of score. The results of histopathological evaluation confirm that histological analysis is a powerful tool in experimental models of this disease.

Published: September 2018

Abstract
Our bibliographic insights have shown that although thermographic imaging in small animals has been poorly studied, the empirical use of thermographic images in dogs suggests that thermographic imaging could be a useful method in assessing walking anomalies. The study aims to identify existing thermal asymmetries between the thermal paw prints of the hind limbs in healthy dogs (right versus left). For thermal investigations, the Flir E50 thermal camera with a resolution of 240×180, thermal sensitivity of 0.05ºC, 45º×34ºA visual field and unbalanced microbolometer was used. Acclimatization of the animals in the space for examination was 30 minutes (at a room temperature of 20-23°C). The resulting images were recorded, processed and analyzed with the Flir tools 2017 software. The average, maximum and minimum temperature of each image was calculated using the program. The results obtained show that between the thermal paws marks of the posterior limbs in healthy dogs there is an average thermal asymmetry comprised between 0.2 and 1.4°C. Our study suggested that, under controlled conditions, thermographic paws prints could be used to diagnose locomotor abnormalities in dogs..

Published: September 2018

Abstract
The experiment was carried out on four groups of Hy-Line var. Brown hens (n = 350 each) fed on diets which provided 2.49, 3.07, 3.78 and, respectively, 4.15 g% calcium (Ca) during the laying period. Consequently, mean daily Ca intake was 2.74, 3.38, 4.16 and 4.60 g/cap., respectively. Ca metabolism was assayed at 20 weeks of age (start of the laying), 36 weeks of age (the peak of the laying) and 68 weeks (the end of the laying period). A significant part of the ingested Ca was not absorbed. The percentage of Ca exonerated by feces was higher at the start of the laying and lowers in the peak of laying and at the end of the laying period. The amount of Ca exonerated as unabsorbed Ca increases as the amount of ingested Ca increases inside of each age level. It was found also an increase of the Ca content of the egg shell according the Ca intake statistically significant (P<0.05) in 36- and 68-wk.-old hens, but not in 20-wk.-old hens. Blood plasma Ca showed significantly higher values in 3.38-, 4.16- and 4.60-g/day-Ca-intake groups when compared by 2.74-g/day-Ca-intake group (P < 0.05) but the level of increasing showed lowest values in hen groups with highest intake of Ca. The daily eggshell Ca export strongly correlates with the amount of daily Ca intake in 36-wk.-old hens and 68-wk.-old hens: r = +0.72 and +0.84, respectively, but no correlation was found in 20-wk.-old hens (r = -0.74, negative correlation). The results showed a limited physiologic capacity of the Ca absorption in hen, the Ca surplus being lost. Dietary Ca level should be closely correlated with the laying level of hens.

Published: September 2018

Abstract
Bisphenol A (BPA) is a compound that is released from PET packaging during storage bottled water and can have a harmful effect on human health. This study aimed to investigate the cytotoxic potential of BPA at the Caco-2 cell line. Bottled water samples coming from two companies were analyzed starting from 1 month to 12 months of storage Quantification of BPA in water stored in PET containers was carried out by a spectrometric method. Calibration was performed for BPA concentrations ranging between 0.01 and 0.09 mg/L. Caco-2 cell cultures were treated for 24 hours with different BPA concentrations (from 0.1 mM to 1 mM). Viability and cell cytotoxicity analysis was performed by MTT assay. BPA concentration in one water sample ranged from 0.09 to 0.92 mg/L while for second water sample BPA concentration ranged from 0.03 to 0.73 mg/L. After 10 months from packing, BPA concentration began to exceed the 0.6 mg/L limit stated by Regulation (EU) no. 10/2011. Cell viability decreased in a dose dependent manner and reached the minimum of 3.8% for the 1 mM BPA concentration.
