    Stevia rebaudiana Bertoni has sweet substances (stevioside) in its leaves that are free of calories and their consumption is beneficial for diabetic patients and is also helpful in high blood pressure also. Because of low capability in seed germination, tissue culture is an appropriate method for propagation of this plant. In the current study, optimization of stevia in vitro cultivation via direct organogenesis with different explants, light intensities and plant hormones has been examined. These treatments included BAP (at 0.5, 1, 1.5 and 2mg/l) in combination with  2,4-D, IBA and NAA (each with concentrations of 0.1, 0.2 and 0.5mg/l) and different light intensities (Dark, 2000, 4000 and 6000 lux). MS was utilized as a basal medium. Results indicated the highest rate of organogenesis (85%) occurred on the axillary buds explants with a medium containing 1.5mg/l BAP + 0.1mg/l NAA under 6000 lux light intensity. Also, the highest range of primary organ per explant (42) with 0.3cm length was achieved at this condition. The most efficient medium for rhizogenesis i.e. 100% root production along with the highest root number (11 with approximately 7.13cm length) was obtained in presence of activated charcoal and 1mg/l of IBA. At the end of rhizogenesis experiments, the plantlet length and node multiplicity were 12.8cm and 7 respectively. Greenhouse cultivation of these plantlets was successful

    Abstract : The lack of students’ speaking skill was one the causes of students’ inactivity in the classroom. Speaking skills that had not been mastered by the students were linguistic factors and non-linguistic factors. The linguistic factors that had been mastered yet by students were pronunciation, intonation, tone pressure, inappropriate duration, and also the sentences used by students were still not effective. The nonlinguistic factors that had been mastered yet by students were lack of bravery, fluency, loudness, and mastering the topic. One of the ways to overcome the problems was by applying cooperative learning strategy through think pair share type (TPS). This research was called Classroom Action Research (CAR). The approaches used in this research were qualitative and quantitative approaches. The respondents of this research were students of class VIII A at MTs Zainul Bahar, Wringin sub-distric, Bondowoso regency. The data analysis was administered whether or not there was an improvement of students’ speaking skill. The result showed that there was an improvement of students’ speaking skill with the percentage of pre-cycle was 25%, the first cycle was 46,9%, the second cycle was 87,5%. Key Words : CAR, linguistic factors and non-linguistic factors, speaking skill, TPS

    Abstract : Diction and style of language is one of the invoices that affects one's speaking skills. When expressing ideas, thounght, and feelings to other, language users often do not state what is meant directly but by using words or terms whose meaning can not be directly interpreted in accordance with the origin or meaning of the term.

    Histological characterization of venom secretory cells in the stinger of 3 stingrays (Dasyatidae) species: Dasyatis bennetti, Himantura walga, Himantura gerrardi, in northern water of Persian Gulf and Oman Sea

    Rays are common elasmobranches in the northern waters of Persian Gulf and Oman Sea that may have one or more mineralized serrated stingers on the whip-like tail. The stingers are covered by epidermal cells among which some can produce venom. When these animals are dorsally touched, the stinger may be introduced into the aggressor by a whip reflex mechanism, causing severe mechanical injuries and inoculating the venom. A comparative morphological characterization of the stinger epidermal tissue of different ray species in the northern part of Persian Gulf and Oman Sea was carried out in this study. EDTA was used for decalcification of stings and conventional histological processes were subsequently employed. The results indicated that structure of dermis and epidermis layers of stings in all species are similar to those of corresponding layers in other parts of fish’s body. The results of the present study have also shown that all three examined species, had venom secretory cells. Distribution of venom secretory cells varies in each species; in Dasyatis bennetti and Himantura walga species, these cells presented in all covered epithelium of stings and in Himantura gerrardi, were in the ventral, ventro-lateral and dorso-lateral of the spine. These differences among the stingers of various species may explain the envenomation severity in these species

    Gerschenkron revisited: The new corporate Russia

    © 2015, Journal of Economic Issues / Association for Evolutionary Economics. Our analysis is based on firm-specific data compiled from the Russian Trading System stock exchange and SKRIN (CKP-H in Russian) database. We seek to identify the factors behind Russias dramatically improved corporate sector performance from the beginning of the 2000s to December 2007. We argue that improved long-term corporate performance was a consequence of several policy initiatives associated with the state-dominated banking sector, which enabled statesubsidized investment funds to be channeled from a structurally reengineered energy sector to targeted investment projects located in other industries. We claim that Russias industrial strategy closely conforms to Alexander Gerschenkrons catch-up theory
