Detector for imaging and dosimetry of laser-driven epithermal neutrons by alpha conversion

An epithermal neutron imager based on detecting alpha particles created via boron neutron capture mechanism is discussed. The diagnostic mainly consists of a mm thick Boron Nitride (BN) sheet (as an alpha converter) in contact with a non-borated cellulose nitride film (LR115 type-II) detector. While the BN absorbs the neutrons in the thermal and epithermal ranges, the fast neutrons register insignificantly on the detector due to their low neutron capture and recoil cross-sections. The use of solid-state nuclear track detectors (SSNTD), unlike image plates, micro-channel plates and scintillators, provide safeguard from the x-rays, gamma-rays and electrons. The diagnostic was tested on a proof-of-principle basis, in front of a laser driven source of moderated neutrons, which suggests the potential of using this diagnostic (BN+SSNTD) for dosimetry and imaging applications.

The 10th Anniversary of the Junior Members and Affiliates of the European Academy of Allergy and Clinical Immunology

This year is the 10th anniversary of the European Academy of Allergy and Clinical Immunology (EAACI) Junior Members and Affiliates (JMAs). The aim of this review is to highlight the work and activities of EAACI JMAs. To this end, we have summarized all the initiatives taken by JMAs during the last 10 yr. EAACI JMAs are currently a group of over 2380 clinicians and scientists under the age of 35 yr, who support the continuous education of the Academy's younger members. For the past decade, JMAs enjoy a steadily increasing number of benefits such as free online access to the Academy's journals, the possibility to apply for Fellowships and the Mentorship Program, travel grants to attend scientific meetings, and many more. In addition, JMAs have been involved in task forces, cooperation schemes with other scientific bodies, organization of JMA focused sessions during EAACI meetings, and participation in the activities of EAACI communication platforms. EAACI JMA activities represent an ideal example of recruiting, training, and educating young scientists in order for them to thrive as future experts in their field. This model may serve as a prototype for other scientific communities, several of which have already adapted similar policies.

Serviços de Ação Social da Universidade de Coimbra: a política de atribuição de bolsas de estudo e o Serviço Social

Este trabalho analisa as políticas de ação social escolar no ensino superior público a partir da década de 60, nomeadamente na atribuição de bolsas de estudo a estudantes da Universidade de Coimbra. Analisa ainda as alterações que estas políticas têm vindo a sofrer ao longo dos anos e a sua relação com o direito ao ensino e igualdade de oportunidades de acesso e êxito escolar consagrado na Constituição Portuguesa. O Serviço Social tem uma intervenção relevante nos Serviços de Ação Social da Universidade de Coimbra, em várias áreas, praticamente desde a sua criação. Neste trabalho, a análise das práticas do Serviço Social centra-se na atribuição de bolsas de estudo, nos últimos 10 anos. Trata-se de um estudo exploratório realizado com base em pesquisa bibliográfica e documental. Outra fonte de recolha de informação foi a entrevista, realizada à Assistente Social, e Responsável pelo Serviço de Bolsas entre 1978 e 2012, Dra. Elisa Decq Motta. As alterações às políticas de ação social no que se refere à atribuição de bolsas de estudo, relacionadas com o cálculo dos rendimentos ou com as condições de elegibilidade, têm vindo a pôr em causa o direito à igualdade de oportunidades dos estudantes, no acesso e na permanência no ensino superior. Muitos deles, economicamente carenciados, estão a ficar de fora do sistema de ação social no ensino superior em virtude destas alterações. É preocupação dos Serviços de Ação Social da Universidade de Coimbra a regressão a que se tem vindo a assistir, e as suas consequências para os estudantes do ensino superior, pelo que é urgente inverter este caminho. / This study analyses the academic social policies in the high-level educational institutions since the 60’s, namely in the allocation of scholarships to students from the University of Coimbra. Furthermore, the changes that such policies have been suffering over the last years, and their relationship with the right to education and equal opportunities to the access and scholar success that every citizen has, as stated by the Portuguese Constitution, are also examined. Since its establishment, the Social Service is a relevant area of the Social Services of the University of Coimbra, in several areas. The analyses present in this study will focus on the last 10 years, specifically on the scholarships allocation. This study is based on literature and documents research, as well as on an interview to the Social Worker responsible for the Scholarships Service from 1978 to 2012, Dra. Elisa Decq Motta. The social policies changes related with the scholarships assignment, especially those associated with the income assessment and eligibility conditions are serious hindrances to the right of equal admission opportunity and maintenance in higher education that all students have. Due to these changes, several students with financial issues are not supported by the social service in higher education. The observed changes, and its consequences for students are a matter of concern for the Social Services of University of Coimbra. It is imperative to revert the current situation.

O processo de criação do programa Universidade para Todos - PROUNI

From the end of the 80s, the Brazilian higher education experience strong growth, coming from the private sector, which would intensify further in the late 90th Higher education has become a lucrative business. With a drop in the number of students entering and strong competition, the number of idle places in private institutions of higher education reached 49.5% in 2004. That same year, by Measure, was the University for All Program (PROUNI) program, to include high school students from public higher education, offering scholarships to those students in private HEIs. In exchange, the IES gain tax exemption. The objective of this research is to investigate the game of interest occurred in the formulation of this program and identify the model and the political game and has led to the creation of PROUNI, analyzing the process occurred since the wording of a bill, the issue of Measure Law and that the legitimacy PROUNI, with the most important changes made initial model. Since the first draft of the Law to the final Act, the PROUNI was disfigured in its main points, as the percentage of stock for paying students, the process of selection of stock and bond of the IES program. Throughout the process of creating the program, it is quite clear the performance of the institutions representing the private higher education. As reference for the analysis was based on Rational Choice Theory of Political Science. The basic argument of the methods based on rational choice is the maximization of the benefit will be the main motivation of individuals, but they can give that your goals can be achieved more effectively through institutional action and thereby discover that their conduct is shaped by institutions. Thus, individuals rationally choose to get to a certain extent constrained to join in certain institutions, whether voluntarily or not. The PROUNI was submitted by government and public policy covered by the mystical aura of the discourse of social justice and economic development, as in higher education includes a stratum of people who would not have access to the university, due to restrictions in the supply network public higher education. However, the greatest benefit from the program are the private HEIs, which through a difficult time in a scenario marked by high competition and idleness of nearly half of the vacancies offered. The PROUNI became a program that prioritizes access and not the residence of the student to higher education. More serious than a supporting program for students Fellows is a program supporting the institutions of private education

History of carp culture in Uganda and progress to December, 1960

Carp (Cyprinus Carpio L.) were first recommend for Uganda in 1941 by Dr. Hornell who was Oolonial Fisheries Adviser at that time. He stated that they would be suitable for Lake Bunyoni (6,474 ft.) in Kigezi District where the cold made conditions marginal for Tilapia and yet where the water was too warm for trout. Later, in 1947, when fish farming was proposed for Uganda, an expert from Israel whose visit was arranged by Dr. Hickling, the then current Colonial Fisheries Adviser, recommended that carp should be used as the stock fish in the ponds rather than Tilapia which Dr. Hickling himself had suggested.

Responses to various protein and energy supplements by steers fed low-quality tropical hay. 1. Comparison of response surfaces for young steers

Response curves were established for different supplements, offered at intakes ranging from 0 to 20 g/kg liveweight (W).day to young Bos indicus crossbred steers fed low-quality Rhodes grass (Chloris gayana) hay ad libitum in two pen experiments. Supplements included protein meals of varying rumen-degradability (cottonseed meal (CSM) or fishmeal), as well as ‘energy sources’ comprising grains of high and low ruminal starch degradability (barley and sorghum) and a highly fermentable sugar source (molasses), with all diets adjusted for rumen-degradable nitrogen and mineral content. Unsupplemented steers gained 0.08 and 0.15 kg/day, in Experiments 1 and 2, respectively. Growth of steers increased linearly with intake of ‘energy source’ supplements in increasing order of molasses, sorghum and barley (all differences P < 0.05). Steer growth rate also increased linearly with fishmeal, albeit over a narrow intake range (0–4.1 g/kg W.day), whereas the response with CSM was asymptotic, showing a steep response at low intake before levelling at ~1.2 kg/day. All supplement types were associated with a linear reduction in hay intake by the steers (energy substitution) where the reduction was greater (P < 0.05) for barley and molasses (not different) than for sorghum (P < 0.05), and for fishmeal compared with CSM (P < 0.05). In concurrent metabolism studies with the same rations, organic matter digestibility of the total ration (561–578 g/kg DM, unsupplemented) was increased linearly by barley and molasses (both P < 0.05) but was unaffected by CSM and sorghum supplements. The efficiency of microbial protein synthesis in steers increased linearly, from 91 g microbial crude protein/kg digestible organic matter (unsupplemented), in both molasses and CSM-supplemented steers, with the trend for a higher response to molasses (P = 0.05), and appeared most closely related to digestible organic matter intake. The response curves from these studies provide the practical framework upon which to formulate rations for cattle grazing low-quality forages.

Growth and development of three key summer grasses in Australian cotton systems

Awnless barnyard grass, feathertop Rhodes grass, and windmill grass are important weeds in Australian cotton systems. In October 2014, an experiment was established to investigate the phenological plasticity of these species. Seed of these species were planted in a glasshouse every four weeks and each cohort grown for 6 months. A developmental response to day length was observed in barnyard grass but not in the other species. Days to maturity increased with each planting for feathertop Rhodes and windmill grass for the first six cohorts. Barnyard grass showed a similar pattern in growth for seeds planted from October to December with an increase in the onset of maturity from 51 to 58 days. However, the onset of maturity for cohorts planted between January and March decreased to between 50 and 52 days. All species had a decrease in the total number of panicles produced from the first four plantings. Feathertop Rhodes grass planted in October produced 41 panicles compared to those planted at the end of December producing 30 panicles, barnyard grass had a decrease from 99 to 47 panicles and windmill grass 37 to 15 panicles on average. By comparing the development of these key weed species over 12 months, detailed information on the phenological plasticity of these species will be obtained. This information will contribute to more informed management decisions by improving our understanding of appropriate weed control timings or herbicide rates depending on weed emergence and development.

The sources of inequity in the education system of Serbia and how to combat them

The concept of equal opportunity for all students is deeply embedded in the Serbian constitution and in education laws. On that level, there is no doubt that everyone is ensured an opportunity to receive quality education. Many measures in education policy have been created specifically to achieve this objective and make the system fair and inclusive. The Coleman Report was linked to a wave of optimism that certain educational measures would help in achieving these noble goals. This aim is a high priority in education in a democratic country, and due to its importance needs to be re-examined. Thus, the present research examines the equity of students in the Serbian education system, detecting areas on all educational levels that could be (or already are) systemic sources of inequity (e.g., criteria for preschool institution enrolment, the system of student awards, rationalisation of the school network, the concept of entrance exams to secondary school or university, etc.). A number of measures have already been taken in the system specifically to deal with inequity (e.g., the Preschool Preparatory Programme, dropout measures, inclusion, scholarships, etc.). The effects of these measures in particular are analysed in the present work. In addition to an analysis of the systemic sources of inequity in the Serbian education system, the article also makes recommendations for their overcoming. (DIPF/Orig.)

Relação universidade-escola: o PIBID como instrumento de intervenção sobre o real da formação de professores

The theme of teacher education has always been rich in discussion and presents an abundant literature on the subject. Historically this topic has generated concerns in both development bodies and universities / schools where these people learn or are engaged in professional work. Training teachers is complex and these elements of complexity make necessary a review of paradigms of initial and continuing education. Despite the efforts of the past decades, the lack of teachers in some areas of knowledge is still a big concern, and it can become even worse in the future, what reinforces the importance of new decisions and new directions in order to change this situation. Therefore, the university-school relationship is of fundamental importance, linking and articulating theory and school practice, contextualizing knowledge, renewing and adapting curricula to current times and spaces in order to be able to improve and recover the social and professional value of teachers. From this perspective the education public policies should turn to the encouragement and the rescue of values and principles in quality teacher training. In the course comes the Institutional Teaching Initiation Scholarships Program - PIBID as an innovative program of teacher education working and adding essential factors to the university-school to reinforce good teaching practices taking up the role of co-developer schools. This research is aimed at analyzing the factors that PIBID inserts in the university-school relationship within IFPR Campus Palmas. The theoretical route was marked by authors as Edgar Morin (2003, 2010a, 2010b, 2012), Enrique Leff (2002a, 2002b, 2003, 2010), Boaventura Sousa Santos (1988, 2010a, 2010b, 2013) Menga Lüdke (2005, 2013), Demerval Saviani (2000, 2013), Paulo Freire (2011), among others, among them official documents of PIBID were used in this research too. The methodological approach with exploratory approach, descriptive explanatory was of fundamental importance through data collected by the documentary analysis (BRAZIL, 2007, 2009, 2013) and in the focus groups activities (GATTI, 2012). The focus groups interlocutors constituted of three groups: Area Coordinators, supervisors and teaching initiation scholarships. The categories were defined a priori from the Programme's objectives and emerging categories identified from the analysis process. After both documentary and interlocutors analysis, it was possible to identify that PIBID inserts the following factors in the university-school relationship: the Recognition of the Profession; Innovative Program and Dialogues of Knowledge. For the recognition of the profession mainly because it is an initial and continuing education program; it approximates theory and practice; upgrades the role of the teacher at school and motivates methodological innovations. This Innovative Program promotes the role of co-educational school and it also approximates knowledge of the school reality and promotes the continuous training. The third emerging category university-school relationship promotes dialogs of knowledge; bringing together theory and practice; it allows information exchange and opens new perspectives for teacher training. Finally, it is possible to realize that besides being a new program, PIBID has promoted visible changes through the actions carried out by all subprojects in partnerships between universities and schools, restoring and giving new meanings to the pedagogical practices.

Accumulation, persistence and effects of indospicine residues in camels fed Indigofera plant

Indospicine (L-2-amino-6-amidinohexanoic acid) is a natural hepatotoxin found in all parts of some Indigofera plants such as I. linnaei and I. spicata. Several studies have documented a susceptibility to this hepatotoxin in different species of animals, including cattle, sheep, dogs and rats, which are associated with mild to severe liver disease after prolonged ingestion. However, there is little published data on the effects of this hepatotoxin in camels, even though Indigofera plants are known to be palatable to camels in central Australia. The secondary poisoning of dogs after prolonged dietary exposure to residual indospicine in camel muscle has raised additional food safety concerns. In this study, a feeding experiment was conducted to investigate the in vivo accumulation, excretion, distribution and histopathological effects of dietary indospicine on camels. Six young camels (2 – 4 year old), weighing 270 − 390 kg were fed daily a roughage diet consisting of Rhodes grass hay and lucerne chaff, supplemented with Indigofera and steam flaked barley. Indigofera (I. spicata) was offered at 597 mg DM/kg body weight (bw)/day designed to deliver 337 µg indospicine/kg bw/day, and fed for a period of 32 days. Blood and muscle biopsies were collected over the period of the study. Concentrations of indospicine in the plasma and muscle biopsy samples were quantitated by validated ultra-performance liquid chromatography−tandem mass spectrometry (UPLC−MS/MS). The highest concentrations in plasma (1.01 mg/L) and muscle (2.63 mg/kg fresh weight (fw)) were found at necropsy (day 33). Other tissues were also collected at necropsy and analysis showed ubiquitous distribution of indospicine, with the highest indospicine accumulation detected in the pancreas (4.86 ± 0.56 mg/kg fw) and liver (3.60 ± 1.34 mg/kg fw); followed by the muscle, heart and kidney. Histopathological examination of liver tissue showed multiple small foci of predominantly mononuclear inflammatory cells. After cessation of Indigofera intake, indospicine present in plasma in the remaining 3 camels had a longer terminal elimination half-life (18.6 days) than muscle (15.9 days), and both demonstrated mono-exponential decreases.

Children exposure to indoor ultrafine particles in urban and rural school environments

Extended exposure to ultrafine particles (UFPs) may lead to consequences in children due to their increased susceptibility when compared to older individuals. Since children spend in average 8 h/day in primary schools, assessing the number concentrations of UFPs in these institutions is important in order to evaluate the health risk for children in primary schools caused by indoor air pollution. Thus, the purpose of this study was to assess and determine the sources of indoor UFP number concentrations in urban and rural Portuguese primary schools. Indoor and outdoor ultrafine particle (UFP) number concentrations were measured in six urban schools (US) and two rural schools (RS) located in the north of Portugal, during the heating season. The mean number concentrations of indoor UFPs were significantly higher in urban schools than in rural ones (10.4 × 10(3) and 5.7 × 10(3) pt/cm(3), respectively). Higher UFP levels were associated with higher squared meters per student, floor levels closer to the ground, chalk boards, furniture or floor covering materials made of wood and windows with double-glazing. Indoor number concentrations of ultrafine-particles were inversely correlated with indoor CO2 levels. In the present work, indoor and outdoor concentrations of UFPs in public primary schools located in urban and rural areas were assessed, and the main sources were identified for each environment. The results not only showed that UFP pollution is present in augmented concentrations in US when compared to RS but also revealed some classroom/school characteristics that influence the concentrations of UFPs in primary schools.

The Apsidal Building of the Vicus Martis Tudertium (PG)

Over the course of the past three seasons (2012-2014) at the putative site of the Vicus Martis Tudertium near the church of S. Maria in Pantano (Massa Martana, PG), excavation has focused on a large structure first observed in crop marks in fall 2008. We have uncovered a large building oriented along the putative Via Flaminia and possessing an apse at its eastern end, the precise function of which remains unclear. Excavation has also uncovered a series of early-medieval burials located just east of the structure.

Sources of Information about Dietary Fibre: A Cross-Country Survey

Problem statement: Dietary fibre (DF) has been recognized as a major determinant for improvement of health. Hence the means of information through which people become aware of its benefits are crucial. Research questions: Where do you usually find information about dietary fibre? What means of communication do you consider the most appropriate to encourage the consumption of dietary fibre? Purpose of the study: This work aimed at studying the sources of information about dietary fibre, as a means to educate people about aspects related to healthy eating. Factors such as gender, level of education, living environment or country were evaluated as to their effect on the selection of sources and preferences.   Research Methods: Descriptive cross-sectional study by means of a questionnaire, applied to a non-probabilistic sample of 6010 participants from 10 countries in different continents (Europe, Africa and America), answered after informed consent by all participants. For the analysis were used several descriptive statistics tools, crosstabs and chi square test to assess the relations between some of the variables under study. Findings: Mostly the information about DF comes from the internet, but television is recognized as suitable. Differences were found between genders, levels of education, living environments and countries. The internet (preferred source), got highest scores for Hungary, urban areas, university education and female gender. The radio (least scored source) was preferred in Egypt, for men and with lower education (primary school). Conclusions: People get information through the internet due to easy access. However, it is to some extent a risk given the impossibility to control de information made public on the internet. The role of health centres and hospitals as well as schools should definitely be increased, as a responsible way to ensure correct information.
