Abstract The aim of the research was to determine to what extent the farinograph and alveograph parameters correlate with each other, and with the physical-chemical parameters, frequently used in the evaluation of wheat flours quality. Thus, 81 samples of wheat flours were analyzed. We found a better correlation of alveographic parameters, such as Extensibility and Mechanical Work (r2 varied between 0.48-0.51), with Protein content and Gluten content of flours, compared to farinographic parameters: Development time and Stability (r2 varied between 0.25-0.35). A poor correlation between farinographicand alveographic parameters was observed, the maximum value of the determination coefficient being r2=0.40, between Stability and Mechanical Work. The factorial analysis led to the highlight of four principal components. The first principal component was strongly correlated with the Protein content (including Gluten) of flours, with most farinographic (except for Water absorptin) and alveographic parameters (Mechanical work, W and Extensibility index, G). This component appears to express the tolerance of flours to the mechanical stress, exerted in the dough phase and their ability to preserve the own viscosity under mechanical stress conditions. The second principal component is related to the dough resistance to deformation, as expressed by the alveographic parameters Resistance and the P/L ratio. Principal components three and four were strongly correlated with flours ash (extraction degree) and amilolytic activity.
摘要本研究的目的是确定在小麦面粉品质评价中常用的粉谱仪和肺泡仪参数之间以及与理化参数之间的关联程度。因此,对81个小麦面粉样本进行了分析。我们发现,与面粉参数、发育时间和稳定性(r2在0.25-0.35之间)相比,肺泡学参数(如可伸性和机械功)与面粉的蛋白质含量和麸质含量(r2在0.48-0.51之间)的相关性更好。在稳定性和机械功之间,测定系数的最大值为r2=0.40。析因分析得出四个主成分的重点。第一个主成分与面粉的蛋白质含量(包括面筋)密切相关,与大多数面粉学参数(吸水率除外)和肺泡学参数(机械功,W和拉伸指数,G)密切相关。该成分似乎表达了面粉对面团阶段施加的机械应力的耐受性以及在机械应力条件下保持自身粘度的能力。第二个主成分与面团抗变形能力有关,由泡形参数和P/L比表示。主成分3和主成分4与面粉灰分(萃取度)和溶淀粉活性密切相关。

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..
我们的文献见解表明,尽管对小动物的热像成像研究很少,但对狗的热像成像的经验使用表明,热像成像可能是评估行走异常的有用方法。该研究旨在确定健康犬后肢热爪印(右爪印与左爪印)之间存在的热不对称性。热成像采用分辨率为240×180,热感度为0.05ºC,视野45º×34ºa的Flir E50热像仪和非平衡微热计。动物在测试空间的适应时间为30分钟(室温为20-23℃)。使用Flir工具2017软件记录、处理和分析生成的图像。利用该程序计算每张图像的平均温度、最高温度和最低温度。结果表明,健康犬后肢热爪标记之间的平均热不对称性在0.2 ~ 1.4℃之间。我们的研究表明,在控制条件下,热成像爪印可用于诊断狗的运动异常。

Abstract The present paper addresses an analysis of the economic, touristic and gastronomic evolution of the county starting from the period before the 1990s until 2016. Initially, the economic growth of Alba County started with its industry, especially the chemical, wood processing, machine building, and food industry, but also with mining. Afterwards, there was a period of economic decline, thereafter the industry in this area started to relaunch, however, below the 1990s level. The results of the study show the existence of many tourist attractions with great potential for growth and it also present the economic growth potential of Sebes, Cugir, Blaj, Alba Iulia, Rosia Montana, Zlatna, Ocna Mures, Arieseni and Aiud. The conclusions of the study highlight the need identified at county level, namely the necessity to turn into account the wine route by expanding accommodation capacities, taking advantage of the touristic objectives, developing the infrastructure and tailoring the offers
本文分析了从20世纪90年代之前到2016年,该县经济、旅游和美食的演变。最初,阿尔巴县的经济增长始于其工业,特别是化学,木材加工,机械制造和食品工业,但也与采矿业。之后,经历了一段经济衰退期,此后该领域的行业开始重新启动,但低于20世纪90年代的水平。研究结果表明,存在许多具有巨大增长潜力的旅游景点,并提出了Sebes, Cugir, Blaj, Alba Iulia, Rosia Montana, Zlatna, Ocna Mures, Arieseni和Aiud的经济增长潜力。该研究的结论强调了在县一级确定的需求,即通过扩大住宿能力、利用旅游目标、发展基础设施和定制服务来考虑葡萄酒路线的必要性

Abstract Sunflower (Helianthus annuus L.) is one of the most important oil crop in the world with a harvested area in 2016 which was 3.9 times more than in 1961. The almost continuous increase of the harvested area at world level is due to the sunflower crop advantages for the farmers and to the increased yielding capacity and oil content in the seeds, all these associated with an increased demand on the market for the sunflower oil. The high yielding capacity associated with high oil content in the seeds is due to the remarkable achievements realized through the breeding programs performed at sunflower crop in the last century. These achievements are related especially to the creation of the high-yielding F1 hybrids with excellent performances. The aim of the present paper is to make an analysis and to give an insight into the situation, evolution, and historical milestones regarding the sunflower varieties and hybrids registered for cultivation in Romania in the last century. In this respect, there were analyzed different informational sources during the last century with respect to the sunflower crop in Romania, but especially the whole collection of the Romanian Official Catalogues of the Varieties of Plant Species. The official journey in Romania of the sunflower as an oil crop started in 1910 and has registered up to present a spectacularly evolution both in terms of cultivated area and varieties and hybrids cultivated.
向日葵(Helianthus annuus L.)是世界上最重要的油料作物之一,2016年的收获面积是1961年的3.9倍。在世界范围内,收获面积几乎持续增加,这是由于向日葵作物对农民的好处,以及种子中产量和含油量的增加,所有这些都与葵花籽油市场需求的增加有关。向日葵的高产能力与种子中的高含油量有关,这是由于上个世纪在向日葵作物育种方面取得的显著成就。这些成就尤其与创造出性能优异的高产F1杂交品种有关。本文的目的是对罗马尼亚上个世纪登记种植的向日葵品种和杂交品种的情况、演变和历史里程碑进行分析和深入了解。在这方面,分析了上个世纪关于罗马尼亚向日葵作物的不同信息来源,特别是罗马尼亚植物品种官方目录的整个收藏。在罗马尼亚,向日葵作为油料作物的正式历程始于1910年,并在种植面积、品种和杂交栽培方面呈现出惊人的进化。

Abstract Soils from agricultural areas are under anthropic pressures, one of the causes being atmospheric deposition of heavy metals. In order to prevent that diffuse pollution affects the soil for long term it is important to reduce the releases of pollutant from air and water. In this paper it was analysed a potential method of chemical remediation applied to the case of an accidental situation of arable soil pollution with heavy metals. The technology of remediation proposed is based on a chemical fixation by adding a reagent into the contaminated soil where it reacts with heavy metals and form insoluble complexes. The organic reagent is one of the best-known and most frequently used in extraction and trace analysis. So, the chemical remediation proposed could decrease the migration of heavy metals in soil and subsequently, in water, plant and other environmental media.
农业地区的土壤受到人为压力,其中一个原因是大气中重金属的沉积。为了防止扩散污染对土壤的长期影响,减少空气和水中污染物的排放是很重要的。本文分析了在耕地土壤重金属污染事故情况下化学修复的可行方法。提出的修复技术是基于化学固定,通过向污染土壤中添加一种试剂,在那里它与重金属反应并形成不溶性络合物。有机试剂是萃取和痕量分析中最著名和最常用的试剂之一。因此,提出的化学修复可以减少重金属在土壤中的迁移,进而减少在水、植物和其他环境介质中的迁移。

Abstract Iris reticulata is one of the most appreciated flower species, being found in both field crops and greenhouse cultures. Our research has as a major objective the study of the influence of particularities of thermic regime from cold period upon the quality of the bulbs flowering. For planting we used bulbs distributed in three equal batches, for each batch, differentiating the period of cold necessary for the rooting of the bulbs. The cold period was provided in three variants: in the refrigerator (5°C), in a shade which climate similar to the outside (5°C), in the cellar (10°C). The introduction of bulbs planted in the greenhouse for forcing was performed for each of the three batches after 4, 6 and 8 weeks of cold storage. The microscopic preparations show that on begin of cold period all the floral elements are formed inside in the bulb. The best quality of the bulbs flowering was obtained on the variants which cold period occurred on the shade, at °5 C temperature.
网纹鸢尾(Iris reticulata)是一种最受欢迎的花卉,在大田作物和温室栽培中都有发现。本研究的主要目的是研究冷期热状态的特殊性对球茎开花质量的影响。种植时,我们将球茎均匀地分成三批,每批区分球茎生根所需的低温期。冷期有三种形式:在冰箱里(5°C),在与外界气候相似的阴凉处(5°C),在地窖里(10°C)。在冷藏4周、6周和8周后,三个批次的球茎都被引入温室进行强制种植。显微观察表明,在寒冷期开始时,所有的花元素都在球茎内部形成。在阴凉处发生冷期、温度为°5℃的变异球茎开花质量最好。

Abstract Anesthetic management of the reptilian patient, including the design of the anesthetic protocol, is a challenge due to multiple anatomical and physiological features. Usually, anesthetic and analgesia protocols, including monitoring techniques, some of which are of low value, established in domestic animals are also applied to these patients. In the study were included five constrictor snakes in which, under xylazine-ketamine-isoflurane anesthesia, various surgical interventions lasting up to 50 minutes were performed. The severity of CNS inhibition as well as the length of different anesthetic times was monitored. The association used ensured the achievement of the surgical anesthesia depth and immobility with optimal conditions for performing surgical interventions in the oral cavity, cutaneous or amputation of hemipenis. The length of induction, surgical anesthesia and recovery fall within the limits recorded in the specialty literature for reptile.
爬行动物患者的麻醉管理,包括麻醉方案的设计,由于多种解剖和生理特征,是一个挑战。通常,麻醉和镇痛方案,包括监测技术,其中一些是低价值的,建立在家畜也适用于这些患者。在这项研究中包括五条蟒蛇,在二甲肼-氯胺酮-异氟醚麻醉下,进行了持续50分钟的各种手术干预。观察不同麻醉时间对中枢神经系统抑制程度的影响。该关联确保了在口腔、皮肤或半阴茎截肢手术中实现手术麻醉深度和固定化的最佳条件。诱导、手术麻醉和恢复的时间长度在爬行动物专业文献中记录的范围内。

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.
摘要双酚A (BPA)是瓶装水在储存过程中从PET包装中释放出来的一种对人体健康有害的化合物。本研究旨在探讨BPA对Caco-2细胞系的细胞毒性。来自两家公司的瓶装水样品从储存1个月到12个月开始进行分析,用光谱法对储存在PET容器中的水中的BPA进行定量分析。校正BPA浓度范围为0.01 ~ 0.09 mg/L。不同BPA浓度(0.1 mM ~ 1mm)处理Caco-2细胞培养24小时。MTT法测定细胞活力和细胞毒性。一个水样的BPA浓度范围为0.09 ~ 0.92 mg/L,另一个水样的BPA浓度范围为0.03 ~ 0.73 mg/L。包装10个月后,BPA浓度开始超过法规(EU) no. 6规定的0.6 mg/L限值。10/2011。细胞活力呈剂量依赖性下降,当BPA浓度为1 mM时,细胞活力最低为3.8%。
