Effort to increase rubber plant production should be done, especially rejuvenation for old rubber plant which in turn require high numbers of seedling within short time period. One of the method to provide rubber plant seedlings within short time period is through grafting technique which combine plant having strong rootas base stem and high production plant as upper stem (entres). The objective of this research was to study response of entres age and clone to growth of rubber seedling (Hevea brasiliensis Muell, Arg.) produced from green and brown grafting. This study was conducted from February 2019 to Februari 2020. This study used Factorial Randomized Block Design with entres age as the first factor consisting of 3, 6, 9, 12 and 15 months as well as clone as the second factor consisting of PB 260 and BPM 24. Data was analyzed by using analysis of variance and followed bywith Honestly Significant Different (HSD) test and regression analysis. The study results showed that the best treatment was entres having 9 months of age as indicated by grafting success, the speed of stum out, stumlength, stumdry weight, root length androot dry weight which had the highest values than that of other treatments. Clone of PB 260 was the best entres that was very compatible with base stem of GT1 clone than that of BPM 24 clone because it gave the highest yield in term of all observed parametes. The interaction between 9 month entres age and PB 260 clone was the best treatment

Field production of organic crops, including herbs, in south Florida is a challenging task due to the subtropical climate and high number of pest and disease pressures. Thus, greenhouse production of organic herbs may provide an alernate to field production. However, there is little published information on selecting media and fertilizers for organic herb production in greenhouses in this climate. Greenhouse trials were conducted during the 2005 and 2006 growing season at the UF/IFAS Tropical Research and Education Center (TREC) in Homestead, Florida. The objectives of the project were to 1) compare several commercially available organic fertilizers for organic greenhouse production of container herbs and 2) compare two commercially available potting media for organic greenhouse production of container herbs. The two potting media (Fafard and Agro-Soils) did not result in significant differences in measured plant mass production, plant tissue nutrients, or leachate chemistry. However, some differences in plant production for basil and dill were identified among the different fertilizer treatments (Natural Safe, Perdue, Fertrell, and Control). These differ- ences were most notable for visual quality, fresh weight, and dry weight measurements. Evaluation of these parameters for basil and dill suggested that the two best fertilizers were Perdue and Fertrell. However, the differences in cost of each fertilizer and the study results suggest that Perdue is a more economic choice for organic herb production of basil and dill.

According to the latest forecasts, it will take 10 years for the world economy to get back to “decent shape”. Some more critical estimates suggest that the whole western world will have a “colossal mess” within the next 5–10 years. Regulators of some major countries significantly and over a short time‑period changed their forecasts for the worse which means that uncertainty in the outlook for the future persists. Indeed, the intensive anti‑crisis measures have reduced the severity of the past problems, however the problems themselves have not disappeared. Moreover, some of them have become more intense — the eurocrisis, excessive debts, global liquidity glut against the backdrop of its deficit in some of market segments. As was the case prior to the crisis, derivatives and high‑risk operations with “junk” bonds grow; budget problems — “fiscal cliff” in the US — and other problems worsen. All of the above forces the regulators to take unprecedented (in their scope and nature) steps. Will they be able to tackle the problems which emerge?

AbstractThe COVID-19 pandemic has forced governments to impose major restrictions on individual freedom in order to stop the spread of the virus. With the successful development of a vaccine, these restrictions are likely to become obsolete—on the condition that people get vaccinated. However, parts of the population have reservations against vaccination. While this is not a recent phenomenon, it might prove a critical one in the context of current attempts to manage the COVID-19 pandemic. Consequently, the task of designing policies suitable for attaining high levels of vaccination deserves enhanced attention. In this study, we use data from the Eurobarometer survey fielded in March 2019. They show that 39% of Europeans consider vaccines to cause the diseases which they should protect against, that 50% believe vaccines have serious side effects, that 32% think that vaccines weaken the immune system, and that 10% do not believe vaccines are tested rigorously before authorization. We find that—even when controlling for important individual-level factors—ideological extremism on both ends of the spectrum explains skepticism of vaccination. We conclude that policymakers must either politicize the issue or form broad alliances among parties and societal groups in order to increase trust in and public support for the vaccines in general and for vaccines against COVID-19 in particular, since the latter were developed in a very short time period and resulted—in particular in case of the AstraZeneca vaccine—in reservations because of the effectiveness and side effects of the new vaccines.

Abstract Background Platypnoea–orthodeoxia syndrome (POS) is an uncommon condition characterized by dyspnoea and arterial desaturation in the standing or sitting position that improves in the supine position. Case summary We report two cases of POS caused by an atrial septal defect (ASD) and a patent foramen ovale (PFO). Both cases reported a recent decrease in body weight of more than 10 kg in a short time period. Transoesophageal echocardiography (TOE) with agitated saline bubble study revealed and a large amount of contrast bubble through the ASD (Patient 1) or the PFO (Patient 2) from the right atrium to the left atrium in the sitting position. Both patients were diagnosed by the finding of positional dyspnoea and the results of TOE using agitated saline bubble contrast. Discussion Taken together, their presentations suggest that weight loss in a short time period could be a pathogenic factor for POS.

Abstract. The Tohoku-Oki earthquake on 11 March 2011 caused significant widespread crustal movements. In a previous study, we proposed a method for capturing two-dimensional (2-D) surface displacements from a pair of pre- and post-event TerraSAR-X (TSX) intensity images. However, it is difficult to detect three-dimensional (3-D) displacements from one pair of TSX images. In this study, three pairs of pre- and post-event TSX images taken on different paths were used to estimate 3-D crustal movements. The relationship between the actual 3-D displacements and the converted 2-D movements in the SAR images was derived based on the observation model of a SAR sensor. The 3-D movements were then calculated from three sets of detected 2-D movements that occurred within a short time period. Compared with GPS observations, the proposed method was found to be capable of detecting the 3-D crustal movements with sub-pixel accuracy.

Inland people’s attitude towards municipal amalgamation reform in Norway from 2013 to 2018 has become more positive. However, a majority does not support the ongoing reform, but the changes have been substantial during such a short time period. However, these changes seem not to be a result of new and more positive judgements of the reforms’ results and outcome. By contrast, the majority has been more critical of anticipated consequences of the amalgamation reform into larger municipalities. Instead, we considered the changes as a type of ‘resignation’ towards a reform pressure from the national government and general changes in their environment. More citizens’ assess that positive municipal economic development and more local competence are favourable effects of mergers, and this finding supports this claim. The reform is likely to catch up with their local units anyway, and the citizens’ attitudes are adapting to what they expect will occur in the upcoming years.

Mushrooms (vegetarian meat/vegetable beef stick) is becoming fast popular because of its short time period between cultivation and harvesting; less initial investment and can be grown with locally available resources. Though more technology is available for boosting mushroom production, the yield so far achieved is not high. Hence, an attempt is made to find out the constraints faced by mushroom growers in adoption of improved mushroom production practices. Samastipur district of Bihar was purposively selected for the study because, Dr. Rajendra Prasad Central Agricultural University, a pioneer in mushroom production technology is located in the study area. 120 respondents from six villages of Pusa, Samastipur, Bihar forms the respondents of the present study. Primary data was collected from the mushroom growers and the responses were subjected to statistical analysis. The results indicated that unavailability of quality spawn, unavailability of skilled labor, absence of technical guidance, high transport cost, unavailability of storage facilities, high cost of spawn and long distance market were the most problematic constraints faced by the mushroom growers. Thus, it can be concluded that adequate extension service should be made available to make mushroom cultivation popular, market and marketing of the products.

Nowadays, a problem of an e- technologies’ implementation represents one of the most important questions that are being solved within various subjects from business area. With respect of massive implementation of activities as e- commerce, e- payments and others the e- technologies’ implementation is the progressive way of these subjects’ expansion. However, due to relatively short time period in which enterprise subjects have solved there is a set of vague aspects going together with this problem. The paper analyses the area of e- technologies and defines relations between basic concepts. Following this theoretical system a few hypothesis are constructed and used as a base platform for a determination of the logical model for implementation of e- technologies in enterprise environment.

In the article the authors give the example of own created methodology of coordinating abilities estimation and upbringing in children with spastic diplegia and hemiparetic forms of infantile cerebral paralysis at the age of 11-12 of the Ist level of functional abilities according to Gross Motor Function Classification Systems. The peculiarity of the methodology is its universal character: the created methodology of estimation helps to estimate within a short time period and in terms of free space deficiency estimate coordinating abilities development. According to the development results estimation of a girl with a hemiparetic form of infantile cerebral paralysis we see the best indices of coordinating abilities development in comparison with the girls with spastic diplegia and the boys of both forms. For coordinating abilities upbringing the authors offer the methodology. It includes two blocks: the 1st block- classical physical exercises; the second block- exercises at stable platform. The authors offer the algorithm of coordinating abilities estimation and upbringing in children with spastic diplegia and hemiparetic forms of infantile cerebral paralysis at the age of 11-12.

A major difficulty with teaching ethics is that it is relatively easy for participants to state the “right” thing to do when they have no personal stake in the outcome. One way of dealing with this problem is to teach ethics through engrossing, immersive, predictive scenario games in which players are forced to deal with ethical issues as they arise, where they have a personal stake in the outcome, and where there is not always a clear right answer. Predictive scenario games are a form of serious live-action roleplaying in which participants take on the roles of people involved in complex situations. In these games, knowledge of the game world is distributed among the players through overlapping and conflicting goals, and in which ethical dilemmas emerge naturally, without fanfare, much as they would in the real world. There is a high level of tension between cooperation and competition among the players. This structure creates the opportunity for players to experience the consequences of their own judgment in realistic, ethically fraught situations, to receive feedback, and to engage in constructive discussion, within a relatively short time period.
