Influência do peso da semente de arroz (Oryza sativa L.) sobre a germinação

The main purpose of this work was to evaluate, through germination tests, the importance of the weight on rice seeds (Orza sativa L.). Batatais, Pratão Precoce. IAC-120, IAC-435 and IAC-1246 varieties were tested. The trial was conducted in the Seed Laboratory of the "Departamento de Agricultura e Horticultura da Escola Superior de Aricultura Luiz de Queiroz", from November, 1973. to December, 1974. Seeds of each variety was submited to a controled ventilation action through a blower, allowing the separation of each variety in to three fractions, with different weights, that is, light, median and heavy. The light, median and heavy seeds obtained were stored indry chamber and in laboratory. The germination tost were done in three periods (March/April, July and December, 1974), using as experimental design a factorial 3x2 whose variables were three weights and two environments of seeds conservation with four replications. Data analyses and the interpretation of the obtained results allowed us to draw the following conclusions: a) the heavy seeds and the median weight ones presented a higher percentage of germination than the light seeds in all studied varieties; b) this effect was less intense in the case of the Batatais and IAC-1246 varieties; c) the dry chamber environment showed superior to the laboratory for he conservation of the seeds.O objetivo principal do presente trabalho foi determinar através do teste de germinação, a importância do peso das sementes de arroz (Oryza sativa L.). Utilizaram-se sementes das variedades Batatais, Pratão Precoce, IAC-120, IAC-435 e IAC-1246. O trabalho foi conduzido no Laboratório de Sementes do D.A.H. da ESALQ no período de novembro de 1973 a dezembro de 1974. As sementes das cinco variedades foram submetidas à ação de ventilação controlada através de um assoprador, permitindo a separação de cada variedade em três frações com pesos diferentes, isto é, leve, média e pesada. As sementes leves, médias e pesadas, assim obtidas, foram armazenadas em câmara seca e laboratório. Os testes de germinação foram efetuados em três épocas (março/abril, julho e dezembro de 1974), utilizando-se como delineamento experimental um fatorial 3x2, cujas variáveis foram três pesos e dois ambientes de conservação das sementes, com quatro repetições. As análises dos dados e a interpretação dos resultados obtidos permitiram que se chegassem às seguintes conclusões: a) as sementes pesadas e médias apresentaram uma maior porcentagem de germinação que as leves em todas as variedades estudadas; b) este efeito foi menos intenso no caso das sementes das variedades Batatais e IAC-1246; c) o ambiente de câmara seca mostrou-se superior ao de laboratório para a conservação das sementes

Knowledge and Acceptance of COVID-19 Vaccination among Undergraduate Students from Central and Southern Italy

At the end of 2020, the Italian Ministry of Health launched a national vaccination campaign to counteract the COVID-19 pandemic. The present study aimed at appraising levels of knowledge about and acceptance of COVID-19 vaccination in a sample of Italian undergraduates during the first phase of the immunization plan. A web-based questionnaire was administered to students attending universities in Bari, Naples, and Rome during the period February-April 2021. Of the total of 3226 participants, 91.9% were keen to receive a COVID-19 vaccination. More than 80% gave correct answers to questions about COVID-19 vaccine administration, functioning, and effects on community health. However, only 63.8% identified the correct composition of the available vaccines. Knowledge was found to be related to sociodemographic features and COVID-19 vaccination acceptance (p < 0.05). COVID-19 vaccination acceptance was found to be related to having a previous vaccination against influenza (OR 3.806, CI 95% 1.181-12.267; p = 0.025) and knowledge (OR 4.759, CI 95% 2.106-10.753; p = 0.000). These results show a good level of awareness about COVID-19 vaccination in this population, which may indicate the effectiveness of communication strategies accompanying the COVID-19 immunization campaign in Italy

Knowledge about tuberculosis among undergraduate health care students in 15 Italian universities: a cross-sectional study

Background: The Italian Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health conducted a multicentre survey aiming to evaluate undergraduate health care students’ knowledge of tuberculosis and tuberculosis control measures in Italy. Methods: In October 2012–June 2013, a sample of medical and nursing students from 15 Italian universities were enrolled on a voluntary basis and asked to complete an anonymous questionnaire investigating both general knowledge of tuberculosis (aetiology, clinical presentation, outcome, screening methods) and personal experiences and practices related to tuberculosis prevention. Data were analysed through multivariable regression using Stata software. Results: The sample consisted of 2,220 students in nursing (72.6%) and medicine (27.4%) courses. Our findings clearly showed that medical students had a better knowledge of tuberculosis than did nursing students. Although the vast majority of the sample (up to 95%) answered questions about tuberculosis aetiology correctly, only 60% of the students gave the correct responses regarding clinical aspects and vaccine details. Overall, 66.9% of the students had been screened for tuberculosis, but less than 20% of those with a negative result on the tuberculin skin test were vaccinated. Multivariable regression analysis showed that age and type of study programme (nursing vs. medical course) were determinants of answering the questions correctly. Conclusions: Although our data showed sufficient knowledge on tuberculosis, this survey underlines the considerable need for improvement in knowledge about the disease, especially among nursing students. In light of the scientific recommendations concerning tuberculosis knowledge among students, progress of current health care curricula aimed to develop students’ skills in this field is needed.</br

Evaluation of humoral and cellular response to four vaccines against COVID-19 in different age groups: A longitudinal study

To date there has been limited head-to-head evaluation of immune responses to different types of COVID-19 vaccines. A real-world population-based longitudinal study was designed with the aim to define the magnitude and duration of immunity induced by each of four different COVID-19 vaccines available in Italy at the time of this study. Overall, 2497 individuals were enrolled at time of their first vaccination (T0). Vaccine-specific antibody responses induced over time by Comirnaty, Spikevax, Vaxzevria, Janssen Ad26.COV2.S and heterologous vaccination were compared up to six months after immunization. On a subset of Comirnaty vaccinees, serology data were correlated with the ability to neutralize a reference SARS-CoV-2 B strain, as well as Delta AY.4 and Omicron BA.1. The frequency of SARS-CoV-2-specific CD4+ T cells, CD8+ T cells, and memory B cells induced by the four different vaccines was assessed six months after the immunization. We found that mRNA vaccines are stronger inducer of anti-Spike IgG and B-memory cell responses. Humoral immune responses are lower in frail elderly subjects. Neutralization of the Delta AY.4 and Omicron BA.1 variants is severely impaired, especially in older individuals. Most vaccinees display a vaccine-specific T-cell memory six months after the vaccination. By describing the immunological response during the first phase of COVID-19 vaccination campaign in different cohorts and considering several aspects of the immunological response, this study allowed to collect key information that could facilitate the implementation of effective prevention and control measures against SARS-CoV-2

The Anticoincidence Shield of the PAMELA Satellite Experiment

The PAMELA space experiment is scheduled for launch towards the end of 2004 on-board a Russian Resurs DK1 satellite, orbiting Earth at an altitude of 300– 600 km. The main scientific goal is a study of the antimatter component of the cosmic radiation. The semipolar orbit (70.4◦) allows PAMELA to investigate a wide range of energies for antiprotons (80 MeV–190 GeV) and positrons (50 MeV– 270 GeV). Three years of data taking will provide unprecedented statistics in this energy range and will set the upper limit for the ratio He/He below 10−7. PAMELA is built around a permanent magnet silicon spectrometer, surrounded by a plastic scintillator anticoincidence shield built at KTH. The anticounter scintillators are used to aid in the rejection of background from particles not cleanly entering the acceptance of the tracker. Information from the anticounter system will be included as a veto in a second level trigger, to exclude the acquisition of events generated by false triggers. An LED-based monitoring system has been developed for the anticounter system. The LEDs mimic the light signal produced in the scintillator by an ionising particle. This allows the functionality of the AC system to be verified in-orbit. The development and testing of the monitoring system are presented and comparisons have been made with independent radioactive source-based calibration methods. The anticounter system has also been extensively tested with cosmic rays and particle beams. Most of these tests have been performed with the anticounters integrated with the other PAMELA subdetectors in a flight-like configuration
