Rosa damascena perfume rose has a considerable place in Morocco. The essential oil, hydrolate (rose water) and dried buds produced in Kalâa Mgouna are intended for export. However, local varieties are not identified. Hence, the objective of our research into the identification of morphological variability by studying 15 qualitative and quantitative characteristics related to leaf, spine and flower at eight localities along the valley of roses. The present study has demonstrated the existence of a great morphological variability within the Kalâa Mgouna’s perfume rose. The characters associated with leaves and spines drive this variability. The PCA analysis identified four morphotypes; the morphotype I whose stems are unarmed, the morphotype II characterized by broad leaves and moderately spiny stems, the morphotype III having stems bearing long spines and whose petals are wider. Finally, the morphotype IV characterized by very thorny stems, leaves of reduced size and whose petals are wider.

Plant habit and production of secondary metabolites in chamomile plants depend on endogenous and exogenous factors that can be divided into two groups (Franz 1982): a) morpho-ontogenetic variability, b) genetic variability or genetic determinateness. The activity of these factors is reflected in biomass production, flower drug production, content and composition of essential oil and some other characteristics of chamomile stands. This study presents genetic and environmental variations of essential oil and its sesquiterpene composition – (-)-B of chamomile population (Lawrence 1986). Qualitative and quantitative characteristics of the chamomile essential oil of selected cultivars indicate (-)- compounds belong to the chemotype C group (Lawrence 1986). Parameters of the composition of essential oil from cultivated chamomile varieties,

To support the crop improvement of Physalis ixopcarpa Brot., 16 accessions provided by National Plant Germ Plasm System USDA (USA) and one recently reported accession from Pakistan were characterized for morphometric and genetic diversity. These accessions were evaluated for morphometric and physiological traits. Among these traits, plant height, relative water content, total chlorophyll content, per cent germination and leaf area were found as best for the differentiation among these accessions. These accessions were also screened for genetic differentiation using RAPDs primers. The genetic similarity among accessions was in the range of 0.03 to 0.33. The RAPD data supported the ecological distribution of accessions. It is inferred from molecular typing that accessions PI512005 and PI360740 were the most diverse accessions among the accessions of P. ixocarpa. In this study the genetic data were deviated from morphometric data which might be due to the qualitative and quantitative characteristics of accessions influenced by environmental factors.

Для рентабельности отрасли табаководства необходимо наличие сортимента сортов табака. Почвенно-климатические зоны Крыма пригодны для возделывания как ценного ароматичного, так и скелетного табачного сырья. Целью данной работы являлось изучение созданных гибридных комбинаций табака старших поколений для выявления перспективы их дальнейшего использования. Селекционерами Института «Магарач» создан ряд перспективных сортов и гибридных комбинаций старших поколений - предшественников сортов табака. В данной работе приведены результаты оценки шести гибридных комбинаций старших поколений, а также перспективного сорта Дюбек Предгорный по основным хозяйственно-ценным признакам. Стандартом служили сорта Американ 14, Американ 307 и Дюбек новый. Работа велась на опытном участке, расположенном в Предгорной зоне Крыма, в течение трех лет. В процессе работы проводились фенологические наблюдения, оценка сортов по показателям продуктивности растений, качеству сухого сырья и другим характеристикам. По результатам исследований наиболее перспективной по урожайности и качеству продукции оказалась гибридная комбинация старшего поколения Ароматный × Американ 572, которая может быть рекомендована как новый сорт табака для введения его в Государственный реестр селекционных достижений, допущенных к использованию. Перспективный сорт Дюбек Предгорный подтвердил хорошие показатели качественных и количественных характеристик для сортотипа Дюбек и рекомендуется для возделывания в фермерских хозяйствах Крыма. Проведенные исследования позволяют увеличить сортовой сортимент крымских сортов табака. For profitability of tobacco industry, there must be an assortment of tobacco varieties. The soil and climatic zones of Crimea are suitable for cultivation of both premium aromatic and skeletal tobacco raw materials. The purpose of this work was to study the selected hybrid combinations of older generations of tobacco to identify prospects for their further use. The Institute Magarach breeders have created a number of promising varieties and hybrid combinations of older generations - the predecessor tobacco varieties. This work presents the results of evaluating six hybrid combinations of older generations, as well as the promising variety ‘Djubeck Predgornyi’ by basic economically valuable traits. The varieties ‘American 14’, ‘American 307’ and ‘Djubeck Novyi’ served as the standard. The work was carried out in the experimental plot located in the Piedmont zone of Crimea for three years. During the working process, phenological observations and the assessment of varieties in terms of plant productivity, quality of dry raw materials and other characteristics were carried out. According to the research results, the most promising in terms of cropping capacity and product quality was the hybrid combination of older generation ‘Aromatnyi’ × ‘American 572’, which can be recommended as a new tobacco variety for its introduction into the State Register of Breeding Achievements approved for use. The promising variety ‘Djubek Predgornyi’ has confirmed good parameters of qualitative and quantitative characteristics for ‘Djubek’ variety, and is recommended for cultivation in Crimean farming. The carried out researches allow increasing the varietal assortment of Crimean tobacco varieties.

Abstract The knowledge of loads and concentrations is fundamental for the design of graywater treatment units, but the data on the characteristics of graywater and in particular graywater solids are weak. As general design values regarding graywater treatment facilities are not available for Germany, the objective of this article is to elaborate the characteristics of graywater and graywater solids. This paper describes the results of six sampling campaigns carried out on graywater systems in the German cities Berlin, Lübeck and Kiel. All graywater samples were collected proportional to the flow and the graywater solids were gathered separately. The collected data include graywater volumes and characteristics regarding the organic pollution (chemical oxygen demand (COD), 5-day biochemical oxygen demand (BOD5)) and nutrients (total nitrogen (TN), total phosphorus (TP)). The graywater volume fluctuated depending on the location. The specific average flow was 68 litre per inhabitant per day (L/inh.d). Inhabitant-specific loads of 49.3 gCODt/inh·d, 28 gBOD5/inh.d, 1 gTNt/inh.d and 0.38 gTPt/inh.d (subscript ‘t’ = total) were found. Information about the composition of graywater solids in terms of quantity and quality is seriously lacking. Therefore, graywater solids were examined with respect to organic matter (COD) and nutrients (TN, TP). The contribution of graywater solids with particle sizes over 200 microns in relation to the total inhabitant-specific load was approximately 3–8% depending on the parameter. The qualitative and quantitative characteristics of the investigated graywater fractions may serve as a base for the estimation of design values.

In these studies, a comprehensive assessment of the effect of the drugs «Carofertin» and «Hemobalance» on the reproductive function of oocyte donor cows was carried out. At the same time, the effect of these drugs on the biochemical parameters of blood serum, as well as on the concentration of progesterone, carotene in the experimental groups and the activity of the ovaries in the experimental animals was assessed. An increase in the activity of alkaline phosphatase in the first and third experimental groups was found, which amounted to 128.80 and 104.6 IU / L. There was also a decrease in the concentration of cholesterol in the experimental groups compared with the control. The maximum concentration of carotene was noted in the experimental group No. 1, which were injected with «Carofertin» subcutaneously, and in the experimental group No. 3, which were injected with «Carofertin» and «Hemobalance». The maximum concentration of progesterone was also noted in groups No. 3 and No. 1 and amounted to 21.98±3.03 and 17.01±9.68 nmol / l, respectively. In the course of ultrasound examination of the ovaries in experimental animals, a relationship was noted between the concentration of progesterone and the intensity of the blood supply of the corpus luteum on the ovaries in experimental animals. Subsequently, in one animal from each experimental group, oocytes were aspirated (OPU) twice with an interval of two weeks and their qualitative and quantitative characteristics were assessed. The maximum number of oocytes suitable for use was noted in the experimental group No. 3, which was injected with both study drugs.

Background: A novel type of control strategy is presented for control of chaotic systems particularly a chaotic robot in joint and workspace which is the result of applying fractional calculus to dynamic sliding mode control. Objectives: To guarantee the sliding mode condition, control law is introduced based on the Lyapunov stability theory. Methods: A control scheme is proposed for reducing the chattering problem in finite time tracking and robust in presence of system matched disturbances. Conclusion: Also, all of chaotic robot's qualitative and quantitative characteristics have been investigated. Numerical simulations indicate viability of our control method. Results: Qualitative and quantitative characteristics of the chaotic robot are all proven to be viable thru simulations.
