ABSTRACT Rice (Oryza spp.), the most important cereal in the world, is grown and consumed in all continents. Brazil is among the top ten producing countries. Stored grains can be attacked by pests (rodents, insects, fungi and mites) that cause serious qualitative and quantitative losses. Because of these losses, one way to alleviate the problem caused by insects during rice storage is the use of resistant materials (grains). Thus, the aim of this study was to evaluate grains from nine different genotypes of rice, in order to identify the existence of materials less susceptible to the attack of Sitophilus zeamais, during 180 days of storage. The mean time of biological cycle (days), susceptibility index (IS) and the number of weevils emerged were evaluated. According to the results, grains of the genotypes IRGA 426 and Puitá were the most susceptible and the genotypes BR-IRGA 409, IRGA 424, IRGA 425 and IRGA 427 were the least susceptible to the attack of Sitophilus zeamais.

CONTEXT: Non-derivative surgical techniques are the treatment of choice for the control of upper digestive tract hemorrhages after schistosomotic portal hypertension. However, recurrent hemorrhaging due to gastroesophagic varices is frequent. OBJECTIVE: To evaluate the outcome of treatment based on embolization of the left gastric vein to control the reoccurrence of hemorrhages caused by gastroesophagic varices in patients with schistosomiasis previously submitted to non-derivative surgery. METHODS: Rates of reoccurrence of hemorrhages and the qualitative and quantitative reduction of gastroesophagic varices in patients undergoing transhepatic embolization of the left gastric vein between December 1999 and January 2009 were studied based on medical charts and follow-up reports. RESULTS: Seven patients with a mean age of 39.3 years underwent percutaneous transhepatic embolization of the left gastric vein. The mean time between azigoportal disconnections employed in combination with splenectomy and the percutaneous approach was 8.4 ± 7.3 years, and the number of episodes of digestive hemorrhaging ranged from 1 to 7 years. No episodes of reoccurrence of hemorrhaging were found during a follow-up period which ranged from 6 months to 7 years. Endoscopic postembolization studies revealed reductions in gastroesophagic varices in all patients compared to preembolization endoscopy. CONCLUSIONS: Percutaneous transhepatic embolization of the left gastric vein in patients with schistosomiasis previously submitted to surgery resulted in a decrease in gastroesophagic varices and was shown to be effective in controlling hemorrhage reoccurrence.

Few women in English literature have distinguished themselves as satirists. But Miss Jane Collier, who is little known even to authorities on the history of English satire, could at times rise to Swiftian irony. An example of how to torment children from her little-known book entitled "An Essay on the Art of Ingeniously Tormenting" follows: . . . That you pursue the method called INDULGENCE, which I have already marked out. This will infallibly make them miserable while infants; as common experience must shew (sic) you, that no children are so fretful, peevish, and uneasy, as those who are so indulged. And although you may, by this means, breed up a parcel of head-strong, hard-hearted cubs, who, when old enough, will defy your power; yet you may, in the mean time, amuse yourself with your servants, your acquaintance, and your friends, who may chance to be more fitted by nature, or education, for your purpose. You may go out of the world, also, with the pleasing reflection, that you have left behind you a set of wolves, cats, and foxes, of your own educating; who will help to plague and torment all the rest of mankind.

Time and expense overruns are regular occurrences in the construction industry all around the world but these are a major concern in developing countries such as India, and their consequences can be extremely harmful when public infrastructure projects are concerned. In India as per the MoS & PI report, as of October 2019, there were 552 delayed construction projects, and the mean time overrun in these 552 delayed projects is29.07 months. Many studies in the literature review previously, have concentrated on a variety of infrastructure risk management issues but there have only been a few studies that have looked into the overall dynamics of infrastructure and how a project's timeline can be affected by changing risk interactions. This article aids in the investigation of the variables and causes of construction delays in infrastructure projects.

Objective: In the middle eastern (MES) and western (WS) societies, sexuality follows different patterns in terms of meaning and rules. Moreover the evolution of societies all around the world created new contexts and kinds of relationship. This could hamper a correct taxonomy of such sexual dysfunctions where social variables are crucial. The aim of the present work is to collect and review data on Unconsummated Marriage (UCM) all around the world, to understand if in different societies it refers to the same situation. Design and Method: A review of published literature on UCM from different areas of the world was conducted. Results: Substantial difference emerged from MES to WS. In MES, sexuality is allowed only in marriage, while in WS sexuality and relationship are not strongly linked. This could suggest that the term “marriage” is unable to cover the phenomenon in such different countries. Moreover, the mean time before the consultation, causal attribution and prevalence are very different in such societies. Conclusions: We found that the term “Honeymoon impotence” could better describe male, female or both difficulties related to ignorance about sexuality or state/performance anxiety, typical in MES. On the other hand in WS over the individual category of sexual dysfunctions, we suggest a new term as “Unconsummated relationship”, where individual difficulties are involved creating a couple’s dysfunction.

ABSTRACTThe outbreak of pneumonia originating in Wuhan, China, has generated 830 confirmed cases, including 26 deaths, as of 24 January 2020. The virus (2019-nCoV) has spread elsewhere in China and to other countries, including South Korea, Thailand, Japan and USA. Fortunately, there has not yet been evidence of sustained human-to-human transmission outside of China. Here we assess the risk of sustained transmission whenever the coronavirus arrives in other countries. Data describing the times from symptom onset to hospitalisation for 47 patients infected in the current outbreak are used to generate an estimate for the probability that an imported case is followed by sustained human-to-human transmission. Under the assumptions that the imported case is representative of the patients in China, and that the 2019-nCoV is similarly transmissible to the SARS coronavirus, the probability that an imported case is followed by sustained human-to-human transmission is 0.37. However, if the mean time from symptom onset to hospitalisation can be halved by intense surveillance, then the probability that an imported case leads to sustained transmission is only 0.005. This emphasises the importance of current surveillance efforts in countries around the world, to ensure that the ongoing outbreak will not become a large global epidemic.

SummaryDue to large inter-individual variations, the dose of vitamin K antagonist required to target the desired hypocoagulability is hardly predictible for a given patient, and the time needed to reach therapeutic equilibrium may be excessively long. This work reports on a simple method for predicting the daily maintenance dose of fluindione after the third intake. In a first step, 37 patients were delivered 20 mg of fluindione once a day, at 6 p.m. for 3 consecutive days. On the morning of the 4th day an INR was performed. During the following days the dose was adjusted to target an INR between 2 and 3. There was a good correlation (r = 0.83, p<0.001) between the INR performed on the morning of day 4 and the daily maintenance dose determined later by successive approximations. This allowed us to write a decisional algorithm to predict the effective maintenance dose of fluindione from the INR performed on day 4. The usefulness and the safety of this approach was tested in a second prospective study on 46 patients receiving fluindione according to the same initial scheme. The predicted dose was compared to the effective dose soon after having reached the equilibrium, then 30 and 90 days after. To within 5 mg (one quarter of a tablet), the predicted dose was the effective dose in 98%, 86% and 81% of the patients at the 3 times respectively. The mean time needed to reach the therapeutic equilibrium was reduced from 13 days in the first study to 6 days in the second study. No hemorrhagic complication occurred. Thus the strategy formerly developed to predict the daily maintenance dose of warfarin from the prothrombin time ratio or the thrombotest performed 3 days after starting the treatment may also be applied to fluindione and the INR measurement.

Hepatitis has become a health problem in the world. The hepatitis virus infected many people. According to the teacher of MTsN 02 Bondowoso more than 20 students have hepatitis A viral infection. The purpose of this research was to know the differences of students' knowledge about hepatitis A before and after counseling in MTsN 02 Bondowoso 2015. This study used pre-experimental (pre-post test design). This study used stratified random sampling technique, 127 students from 270 sample involved this research,and 143 students was excluded. We used questionnaires to collect data. The results showed that the mean value of the students 'knowledge about hepatitis A before counseling in MTsN 02 Bondowoso 2015 was 83.96 with the lowest value of 37.5 and the highest value was 100. The mean value of the students' knowledge about hepatitis A after counseling in MTsN 02 Bondowoso 2015 was 93.21 with the lowest value waf 62.5 and the highest value was 100. Paired t test showed that t (-9.07) > t table (1.98), the null hypothesis (H0) was rejected. There was a difference between students' knowledge about hepatitis A before and after counseling in MTsN 02 Bondowoso 2015. This study showed that routine counseling by healthcare provider was important to prevent hepatitis A infection.; Keywords: counseling, knowledge of students, hepatitis

This paper demonstrates how a range of linguistic methods can be harnessed in pursuit of a deeper understanding of the ‘lived experience’ of psychological disorders. It argues that such methods should be applied more in medical contexts, especially in medical humanities. Key extracts from The Unabridged Journals of Sylvia Plath are examined, as a case study of the experience of depression. Combinations of qualitative and quantitative linguistic methods, and inter- and intra-textual comparisons are used to consider distinctive patterns in the use of metaphor, personal pronouns and (the semantics of) verbs, as well as other relevant aspects of language. Qualitative techniques provide in-depth insights, while quantitative corpus methods make the analyses more robust and ensure the breadth necessary to gain insights into the individual experience. Depression emerges as a highly complex and sometimes potentially contradictory experience for Plath, involving both a sense of apathy and inner turmoil. It involves a sense of a split self, trapped in a state that one cannot overcome, and intense self-focus, a turning in on oneself and a view of the world that is both more negative and more polarized than the norm. It is argued that a linguistic approach is useful beyond this specific case.
