Orchids are considered one of the most important potted-flowering in the world. Oncidium genus, as well their hybrids group (OHGs) has used for the flower market as pot or cut flower.  However, some horticultural characteristics require improvements, e.g. the production of precocious cultivars, independent-season blooming or easy flowering induction, high quality and durability of flowers and variations in color of flowers, to compete with Phalaenopsis and Dendrobium orchids, as other flower groups. Aiming this purpose there were used hand-crossing pollination between the Oncidium ‘Sweet Sugar’ and Ionopsis utricularioides, a Brazilian wild species, for evaluate the capacity of crossing and to select progenies with interest of use in floriculture as new cultivar. The seeds obtained from this cross were seeded on in vitro conditions, followed by acclimatization and cultivation on greenhouse conditions until de flowering time. One of the plants obtained presented interesting characteristics, as good and rapid vegetative development and high quality of blooming. This hybrid obtained from an intergeneric crossing resulted in a plant with vegetative and flower type characteristics and color similar of Oncidium female parent, but with larger number of ramifications in inflorescence and number of flowers (60% and 219,4%, respectively) than Oncidium parent (♀), and with more similarity with Ionopsis (♂). This hybrid cultivar, called Ionocidium ‘Cerrado 101’ is one more option of OHGs in this competitive market and can be used either for pot and also for cut orchid flowers production, main because it longer inflorescence (83 cm).

AbstractThis article examines the international determinants of capital structure using a large sample of firms from 37 countries. The reliable determinants for leverage are firm size, tangibility, industry leverage, profits, and inflation. The quality of the countries’ institutions affects leverage and the adjustment speed toward target leverage in significant ways. High-quality institutions lead to faster leverage adjustments, whereas laws and traditions that safeguard debt holders relative to stockholders (e.g., more effective bankruptcy procedures and stronger creditor protection) lead to higher leverage.

Stem Quality

Rosa sp. is the leading cut flower commercialized in Brazil and in the world; and to maintain stem quality it should be stored at 1 °C, however, there are still doubts about the storage of roses, especially whether the stems should be cold stored in water before marketing. In order to assess the feasibility of wet and dry storage, rose stems, ‘Avalanche’ were stored for 28 days in both conditions at 1 ± 2 °C / 95% RH. Weekly stems batches were transferred to 25 °C / 70% RH and kept in vessels containing tap water for postharvest assessment. It was observed that the decrease in the quality of the roses was inversely proportional to the storage time in both treatments. Although wet storage can occur for up to 21 days, when you need to store roses for a week or two, cold storage in dry condition is advised since it is more economical and viable for the producer.

Quality Of Products

In the world, product quality has long been one of the major instruments for ensuring the economic development of companies. Achieving high quality parameters, in turn, is an important part of the economic strategy of any success-oriented business organization. The article is aimed at developing directions for improving products of PJSC «Beer and Non-Alcoholic Plant «Radomyshl». The object of the research is the quality of beer produced by PJSC «Beer and Non-Alcoholic Plant «Radomyshl». The assessment of the quality level of the selected product in accordance with the requirements of DSTU 3888:2015 was carried out using the following groups of indicators: microbiological, organoleptic and physic-chemical. The process of assessing the product quality parameters is presented, which consists of seven consecutive stages and is carried out throughout the product life cycle. The factors under the influence of which the quality of products are formed and which may cause deviation from the specified quality parameters are analyzed and structured. The defects that appear due to these factors have been identified. The basis for improving the quality of products is primarily a thorough study of changes in demand for the business organization products. Three groups of measures are singled out, with the help of which one can achieve the desired level of product quality, namely: technological, organizational and socio-economic. A complex of priority measures to improve the quality of products of PJSC «Beer and Non-Alcoholic Plant «Radomyshl» is proposed. The element of scientific novelty is the development of an algorithm for the implementation of measures to improve the quality of products. During the implementation of measures to improve the quality, it is necessary to carry out systematic monitoring and generate reports on the implementation of the project in order to make possible an adjustment of the final result.

Do So

One autumn out of four, election forecasting surpasses baseball as America's national pastime. Then, everyone wants to know who will win, and everyone has a guess. Now, with the ballots carefully counted, forecasters await their awards. Below, I evaluate the quality of a wide range of 1984 presidential and congressional forecasts. The evaluation proceeds from nonscientific to scientific approaches, although this distinction is sometimes blurred. To lower the level of suspense, I should say that some forecasts turned out to be quite good. By way of conclusion, I offer a set of rules for selecting a high-quality forecasting instrument.Lucky GuessesMany popular election forecasting rules take advantage of chance, which has been working in their favor. Perhaps the most famous is the World Series forecast, which says, “If the American League wins the World Series, then the Republican presidential candidate will win.” This technique was accurate from 1952 to 1976, missed in 1980, but worked again in 1984 with the victory of the Detroit Tigers. A lesser known rule of this type, which is my personal favorite, is based on the Beaujolais wine harvest. Accordingly, “If the Beaujolais vintage looks bad, then the Republican will take the presidency.” This has held post-1960, and continues to do so with the poor 1984 crop (yielding a wine too light, with little color). There are other such rules that relate more directly to the candidates themselves and, in that sense, have more verisimilitude.

ABSTRACTIn vitro method to fasten availability high quality soybean seedsSoybean is an important crop as a source of food and its demand has increased every year. Several new varieties of soybean have been generated, but the number is still limited. Furthermore, the infestation of pests and infection of diseases have also limited the new soybean varieties production as it increase the risk of growth failure. Therefore, methods to fasten the availability of high quality of soybean seeds need to be developed. One of which can be done through in vitro culture method. The objective of this study was to obtain the best type and the best concentration of cytokinin for the growth of soybean explants in vitro. The experiment was conducted in Seed Technology and Tissue Technology Laboratory, Faculty of Agriculture, Universitas Padjadjaran. The experimental design used was Completely Randomized Design with 13 treatments and four replications. The basic media used were Murashige and Skoog (MS) + Vitamin B5 with addition of BAP (1.0 mg/l, 1.5 mg/l, and 2.0 mg/l), Kinetin (0.5 mg/l, 1.0 mg/l, and 1.5 mg/l), TDZ (0.01 mg/l, 0.1 mg/l, and 1.0 mg/l), and coconut water (10%, 15%, and 20%). The result showed that cytokinin types and concentrations gave different effect to soybean explant growth. The best treatment was demonstrated by BAP at the concentration of 1.5 mg/l as shown by the highest percentage of leaves and the number of shoots. However, it did not affect the percentage of buds produced by explant and the percentage of callus produced by explant.Keyword : BAP, Kinetin, TDZ, Coconut water, Soybean.AbstrakKedelai merupakan komoditas yang memegang peranan penting. Permintaan akan kedelai meningkat setiap tahunnya. Varietas kedelai baru yang bersifat unggul sudah banyak dihasilkan, namun jumlahnya masih terbatas. Tingginya serangan hama dan penyakit saat perbanyakkan benih di lapangan menyebabkan tingginya resiko kegagalan dalam pertumbuhan varietas baru tersebut. Sehingga perlu dilakukan percepatan penyediaan benih sumber varietas unggul di laboratorium secara in vitro. Tujuan penelitian ini adalah untuk mendapatkan jenis dan konsentrasi sitokinin yang terbaik untuk pertumbuhan eksplan kedelai in vitro. Penelitian dilakukan di Laboratorium Kultur Jaringan Teknologi Benih Fakultas Pertanian Universitas Padjadjaran. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan tiga belas perlakuan dan empat ulangan. Media dasar yang digunakan adalah Murashige dan Skoog (MS) + Vitamin B5 dengan penambahan BAP (1,0 mg/l; 1,5 mg/l; 2,0 mg/l), Kinetin (0,5 mg/l; 1,0 mg/l; 1,5 mg/l), TDZ (0,01 mg/l; 0,1 mg/l; 1,0 mg/l), dan air kelapa (10%; 15%; 20%). Hasil percobaan menunjukkan bahwa pemberian jenis dan konsentrasi sitokinin memberikan pengaruh yang berbeda terhadap pertumbuhan eksplan. Perlakuan terbaik diperoleh pada BAP dengankonsentrasi 1,5 mg/l yang ditunjukkan dengan tingginya persentase jumlah daun dan tunas yang terbentuk. Akan tetapi, penambahan sitokinin tersebut tidak memberikan pengaruh terhadap persentase eksplan dalam membentuk tunas dan persentase eksplan dalam membentuk kalus.Kata Kunci : BAP, Kinetin, TDZ, Air Kelapa, Kedelai

Quality Of Research

In 2014, the UK-based Nuffield Council on Bioethics carried out a series of engagement activities, including an online survey to which 970 people responded, and 15 discussion events at universities around the UK to explore the culture of research in the UK and its effect on ethical conduct in science and the quality of research. The findings of the project were published in December 2014 and the main points are summarised here. We found that scientists are motivated in their work to find out more about the world and to benefit society, and that they believe collaboration, multidisciplinarity, openness and creativity are important for the production of high quality science. However, in some cases, our findings suggest, the culture of research in higher education institutions does not support or encourage these goals or activities. For example, high levels of competition and perceptions about how scientists are assessed for jobs and funding are reportedly contributing to a loss of creativity in science, less collaboration and poor research practices. The project led to suggestions for action for funding bodies, research institutions, publishers and editors, professional bodies and individual researchers.

The lemon plant (Citrus limon L.) is a species from the Rutaceae family that spread from Southeast Asia and spread to all countries in the world. Lemon has been used traditionally since ancient times to treat various diseases and has been tested for various pharmacological activities. The literature review was carried out to study the phytochemical compounds and pharmacological activities of lemon plants. The literature compiled by a minimum of 50 scientific articles using search engines such as Science Direct, Pubmed, and Google Scholar, published for a maximum of the last 10 years, includes a minimum of 20 articles in the last 2 years, has a DOI, and the quality of the journal index is reviewed using Scimago. Lemon is very rich in phytochemical compounds, including flavanones such as hesperidin, eriocytrin, naringin, narirutin, didymin; flavones such as apigenin, luteolin, and diosmin; flavonols such as routine, quercetin, mirisetin, isositrol, limositrol, and limositrin; terpenoids such as limonene, limonoids, and carotenoids. Various kinds of in vivo and in vitro studies provide results of various pharmacological activities such as antioxidants, anticancer, neuroprotective, antimicrobial, antidiabetic, anti-inflammatory, antihyperlipidemic, antiurolithiasis, and antiplasmodial. It is necessary to develop further research on the pharmacological activity of lemon plants in the future.

The grave from Gokstad in Norway, dating to ca 900 AD, is one of the best-preserved Viking Age ship graves in the world. The grave mound contained a variety of goods along with human remains, buried in a Viking ship. Several textiles, including embroideries and shreds of what might have been the ship’s tent, were also found. The colors of the textile fragments are now severely faded, but the high quality of the embroidery made of gold and silk threads is still apparent. The style of the embroidery is exceptional, having no equivalents in other Scandinavian graves. The analyses by HPLC coupled with both diode array and mass spectrometric detectors revealed that the striped “tent” cloth as well as the silk thread used for the embroidery were originally dyed with anthraquinones of plant origin (alizarin, purpurin, pseudopurpurin, and anthragallol), markers of madder-type dyestuffs.
