Traditional Term

The evolution of such terms as growth, differentiation, development, morphogenesis etc. is discussed. It is proposed that the term (notion) development should be understood to comprise "growth", "differentiation" and even "abscission, abortion and necrosis". The term "development" is already used in such a way by some authors. The relations among the phenomena denoted by the above terms are presented in a graphic form to show that they partly overlap. The concept that growth and development represent quantitative and qualitative aspects (respectively) of plant augmentation is criticized. The newly introduced terms "development hormone" or "development regulator" seem more suitable than "growth hormone" and "growth regulator", however, these later ones are correct and may be used. The traditional term "phytohormone" and the newly introduced one "phytoregulator" seem convenient, but it must be kept in mind that such substances may transmit information both on a chemical basis as well as on a biophysical one. An example here can be auxin; a change in the wavy character of its transport may serve as information. In some cases a complex of two or more substances may play the role of a hormone, for instance ACC and ethylene, of which one is easily transportable but little active and the other is very active but exerts its action rather locally. Other combinations of activities may exist in other such pairs.

Tourist Village

The tourism sector has become a truly global force for promoting economic growth and development. Therefore, the study of tourism has become an interesting topic for researchers lately. On the other hand, local tourism, generally in developing countries, is often neglected by academics and policymakers. For this reason, this study aims to examine and analyze the role of tourist motivation in mediating accessibility, amenities, and attractions on visiting decisions. This study is a survey research with an explanatory method. The population is tourists who visit the tourism village of Bumiaji, Indonesia, in the low and busy seasons. The population is infinite and the number of respondents who were interviewed is 100 respondents; data were collected by distributing questionnaires to domestic tourists who came from outside the tourist village of Bumiaji, then the data were processed and analyzed using Warp Partial Least Squares. The findings indicate that the effect of accessibility on visiting decisions is not mediated by tourist motivation. This shows that the decision of tourists to visit can be directly influenced by the time and means of transportation available. Meanwhile, the influence of amenities and attractions on the decision to visit is mediated by the motivation of tourists. This means that amenities and attractions can influence a tourist’s decision to visit if there is an urge from tourist to relax or make friends or enjoy the culture at tourist attractions, etc.

Dietary Treatments

The objective of the present work was to investigate the influence of four diets on population growth, development, total length, dry weight, and nutritional value of two zooplanktonic species, Moina micrura and Diaphanosoma birgei. The four dietary treatments were: algae alone (A); algae + vitamins (AV); algae + ration (AR); and algae + ration + vitamins (ARV). Growth rate peak for both species occurred faster with AV treatment. In general, AV treatment for M. micrura showed better results for intrinsic rate, fecundity, and embryonic and post-embryonic development. On the other hand, longevity and total spawning number were better with AR treatment (p < 0.05). Vitamin and ration treatments produced the best results in D. birgei species (p < 0.05). The highest percentage of protein and lipids for both cladocerans was verified for ration treatments. Carbohydrate was higher for the treatment containing algae alone (p < 0.05). Generally, diets containing ration and vitamin showed better results in cladocerans development, with water quality adequate for culture systems. Ration and vitamin diets may also be used in high-density cultures in the laboratory.

Summary During the 2014-2016 period in Agroecological Center at the Agricultural University - Plovdiv, Bulgaria growth and development of three species of wheat in terms of organic farming had been tracked in order to return the species in the crop rotation, maintenance of biodiversity and receiving of cleaner and healthy products from organic farms. The three species of wheat Triticum monococcum L., Triticum dicoccum Sch, and Triticum spelta L., differ between its rate of growth, development, general and productive tillering. In tillering phase the plants reached 12,3 cm of height for Triticum monococcum L., 15,7 cm for Triticum spelta L. and 19,4 cm for Triticum dicoccum Sch. Triticum monococcum L. and Triticum dicoccum Sch, reached ear formation phase 5 days earlier than Triticum spelta L. The interfacial period of stem elongation - ear formation in them, was about 21 days compared to 25 days for Triticum spelta L.. From ear formation to full maturity inter-phase periods were shorter in Triticum dicoccum Sch., which specifies the species as an early mature (6 days earlier) compared to the other two. After phenophase of stem elongation plants were growing the most intensive and in full ripeness reached a height of 94 cm in Triticum monococcum L., 81,5 cm in Triticum dicoccum Sch. and 82,5 cm in Triticum spelta L.

Abstract Background: Melatonin (MEL) plays an important role in regulating the growth and development of organism and the metabolism of cells. A study was conducted to explore the effect of MEL-mediated monochromatic light on the secretion of somatostatin (SST) in the hypothalamus and pituitary.Results: The newly hatched broilers were exposed to white (WL), red (RL), green (GL) and blue (BL) lights through the pinealectomy model. The results showed that SST immunoreactive neurons and fibers were distributed in hypothalamus. The mRNA and protein levels of SST and SST receptor 2 (SSTR2) in hypothalamus and pituitary in RL were higher than those of in GL and BL. After pinealectomy, mRNA and protein levels of SST and SSTR2 in hypothalamus and pituitary in different light groups were increased and the differences were disapeared. Meanwhile, the trend of SSTR5 mRNA in pituitary is the same as the SSTR2 mRNA in pituitary. In vitro, the exogenous SST inhibited the growth hormone (GH) secretion, and SSTR2 and SSTR5 selective antogonists promoted GH secretion. While, melatonin receptor 1b (Mel1b) and Mel1c selective antagonists increased relative concentraitons of SST in adenohypophysis cells.Conclusion: Monochromatic light affected the expression of SST in chick hypothalamus and pituitary. MEL via Mel1b and Mel1c decreased SST secretion under GL, which is related to inhibiting the combination of SST, SSTR2 and SSTR5 in adenohypophysis cells.

Education Science

We can say indubitable that education is one of the main elements of economic growth and development of each country. Even, some believe that evolution and progress of this part causes progress of the other parts. Economics education is a combination of word “economy” and “education” that study usage of economics in the education system; hereby, it considers a branch of economics. And it considers one of the courses of education science because it attends to recognition of economic issues of education and improvement of efficiency of education system. So, for acquaintance with economics education, it’s necessary to first understand the economics and its related objects; it means that we should have perfect and exact recognition about current expenditure that pay for education of manpower. Moreover, it can be mentioned to the role of education as a collector of force and human capital needed for economic and social development of communities. In this article, it is mentioned to education in Iran as for its high expenditure.

The role of photoperiod and irradiance level on growth and development of lettuce was investigated at two stages of plant growth. Vegetative dry weights and the number of leaves are primarily influenced by length of the photoperiod with most growth occurring under long photoperiods and high irradiances. Leaf area of mature plants was related to the input of light energy suggesting a photoregulatory process in the plant that optimizes leaf size for intercepting a constant amount of photosynthetic light.Key words: Lactuca sativa, growth, development, photoperiod, irradiance, light energy

Abstract Survival, feed efficiency, growth, and fertility of swine are dependent on colostrum intake in the first 24 h after birth. This study determined the effects of three doses of a homogeneous colostrum sample on 24-h body weight, rectal temperature (RT), immunocrit, and growth and survival to postnatal day (PND) 7. Three female piglets were selected from eight litters (n = 24 piglets) at birth, removed from their litter, and bottle-fed 10% (COL10, n = 8), 15% (COL15, n = 8), or 20% (COL20, n = 8) colostrum based on birth weight over 12 bottle feedings every 2 h. At 24 h, piglets were weighed, RT recorded, and blood was collected to measure immunocrit. Piglets were returned to the litter of origin, and weight was measured daily until PND 7. Colostrum dose had an overall effect on weight gain at 24 h, RT, immunocrit, and growth to PND 7 (P &lt; 0.05). Piglets in the 20% BrW colostrum group had greater weight gain, RT, and immunocrit at 24 h than COL10 piglets (P &lt; 0.05), but these variables were not different between COL15 and the other treatments. Despite no difference in average daily gain after being returned to their litters, the greater weight (P &lt; 0.05) in COL20 compared to COL10 and COL15 was sustained over 7 d. Seven piglets in each treatment survived to PND 7. This model using standardized doses of a homogeneous colostrum sample enables controlled studies aimed at understanding the role of 24-h colostrum intake on piglet development.
