This study aimed to analyze economically different control protocols for beef cattle gastrointestinal nematodes in Brazil. Field study data previously published was used to compare three groups: 1) non-dosed; 2) current deworming program with two doses - May and November; and 3) alternative strategic control program with three doses - May, August, and November. An economic sensitivity analysis was performed based on beef carcass price (BCP) variation, thus creating three economic scenarios: 1) more probable (M) using the mean BCP in the studied region; 2) optimistic (O) using the mean BCP plus standard deviation; and 3) pessimistic (P) using the mean BCP minus standard deviation. Stock valuation (SV), operational result (OP), and treatment differential (TD) were calculated for each scenario. Average BCP was US$ 2.93 kg-1 carcass (± US$ 0.27 kg-1 carcass). The mean annual cost of deworming per animal was US$ 5.43 and US$ 7.97 for protocols with two and three doses, respectively. The cost of anthelmintic treatment represented 0.63% and 0.74% of operating results, both in M scenario. TD ranged from 9.5% to 27.6% for the assessed protocols. Regardless of the scenario, the protocol with three annual dosages presented the highest SV and OP, which economically justifies its implementation in strategic control of gastrointestinal nematodes in grazing beef cattle in Central Brazil. These results also demonstrate the relevance of strategic anthelmintic treatments in weaned stocker calves in tropical and humid subtropical areas.

Lead (Pb) poisoning remains a common cause of morbidity in dairy and beef cattle. Although Pb toxicosis is typically diagnosed in cattle with clinical signs of acute or subacute Pb poisoning, it has been hypothesized that subclinical chronic exposure of cattle to Pb, which often goes undiagnosed, poses more of a risk to the human consumer. There is not adequate information on Pb kinetics to determine when or if Pb-exposed cattle can safely enter the food chain. The objectives of the current study were to determine whether subclinical elevations in blood Pb (bPb) were present in cattle from herds where 1 or more individuals had clinical Pb poisoning and to determine the half-life (t1/2) of bPb in Pb-exposed cattle. Samples of blood were collected and analyzed for Pb from 126 cattle from 9 farms. Blood lead concentrations ranged from below the detection limit (2.50 µg/dl) to 423.0 µg/dl. Only 11 of the 94 cattle with detectable bPb had clinical signs such as diarrhea, blindness, bruxism, or seizures. When possible, cattle with detectable bPb had serial samples taken. The mean t1/2 calculated from 44 serially sampled cattle was 135 days (standard deviation: 125 days, range: 3–577 days). A source of Pb on the farm was determined for all but one herd.

This study aimed to evaluate the polypharmacy extent and the frequency and severity of drug interactions by evaluating inpatients in the emergency department. In this epidemiologicaldescriptive study, data were collected retrospectively by reviewing medical records of 92 hospitalized patients in the emergency department with a stay over 48 hours. Out of the study population, 54.3% and 45.7% were respectively male and female, with a mean age of 59.09. In terms of hospitalization, 27.2% and 16.3% were hospitalized due to heart problems and trauma, respectively and the mean length of hospitalization was 3.91 with a standard deviation of 2.57 days. The mean drug received was 8.48, with a standard deviation of 4.48. Of the patients, 81.5% received more than 5 drugs; in addition, the observed amounts of drug interactions of A, B, C, D, and X were 2.5%, 17%, 59.3%, 19.5%, and 1.9%, respectively. The drug interaction prevalence in inpatients in the emergency department was high. The presence of a pharmacist is necessary to identify drug interactions and reduce drug-therapy problems to provide quality services.

This study aimed to carry out the morphological characterization of the remaining specimens of the Curraleiro horse in municipalities of the state of Goiás, Brazil. Forty male horses were evaluated using the age of five years as a criterion. Sixteen linear measurements and 13 zootechnical indices were obtained. Subsequently, the mean, standard deviation, minimum, maximum, and covariances of these measures and indices were obtained using the software IBM SPSS Statistics for Windows. The measures withers height (WH), croup height (CH), midback height (MH), sternum-to-ground height (SH), chest index (CI), and estimated weight (W) allowed characterizing Curraleiro horses as small-sized, light, and fast, with proportional measures. The dactyl-thoracic index (DTI), body index (BI), conformation index (CFI), load index 1 and 2 (LOI1 and LOI2), and compactness index 1 and 2 (COI1 and COI2) showed that the Curraleiro horse has an intermediate capacity for speed and strength, bearing considerable weight on the back, with saddling aptitude and fast work. These results represent the beginning of the formation of a database that may contribute to future studies and the conservation of the Curraleiro horse in the state of Goiás.

The digitization of materials in education is a sophisticated platform that is increasingly being used by Malay language teachers in the classroom. This digitization is increasingly imposed by teachers, and many related studies that have been done. In line with this research, the study was conducted to examine the significant effectiveness of Malay language teacher’s confidence and self-proactivity on the use of digital materials in the teaching of factual essays. The study revolved around teacher’s opinions based on the dimensions of self-confidence and proactiveness. A survey method through a quantitative study design based on questionnaires is used in this research. The study sample consisted of 30 Malay language teachers for secondary schools in the district of Shah Alam, Selangor. The study data were analyzed descriptively; mean and standard deviation. The inferential data were from the One-Sample t-Test to test the mean effectiveness of each dimension. The results of this study show that there is a significant mean difference for both dimensions. For the self-confidence dimension, t = 37.1, while the self-proactivity dimension, t = 49.6. Both dimensions were set a significance level <0.05 (df = 29). Implications from this study suggest that self-confidence and proactiveness are important to be measured by teachers so that the use of digital materials becomes an active new norm in the context of factual essay teaching in the 21st century. It is recommended that teachers be given extensive exposure to the use of digital materials in the classroom. The purpose is to increase the stimulus of Malay language teachers in the context of the use of ICT-based materials.

This research analyzes the ICT Competencies of Pre-services Teachers in Papua, including the Region of Sorong, Merauke, Jayapura, and Manokwari. This research aims to discover the students of Teachers' Training Faculty spread in Papua competencies on ICT. The measurement of ICT competencies is carried out using a model developed by Tondeur for preservice teachersusing questionnaires that consisted of 19 items. Questionnaires were distributed to Papua Region covering Jayapura and Merauke, West Papua region covering Sorong and Manokwari. Sixty-eight respondents became the data in this study. Data were analyzed using XL Stats to find the mean and standard deviation. The findings in this study were; the low competencies were found on Papuan Indigenous Pre-service teachers, and the high competencies were found in science discipline compared to non-science in Papua and West Papua Indonesia. The low ability of native Papuan students in managing information in the digital world is indicated by the lack of awareness of preservice teachers in developing a sense of responsibility in using ICT as a communication medium and activities involving ICT use.

SummaryThe characteristics of experimental error in measurement of platelet radioactivity have been explored by blind replicate determinations on specimens taken on several days on each of three Walker hounds.Analysis suggests that it is not unreasonable to suppose that error for each sample is normally distributed ; and while there is evidence that the variance is heterogeneous, no systematic relationship has been discovered between the mean and the standard deviation of the determinations on individual samples. Thus, since it would be impracticable for investigators to do replicate determinations as a routine, no improvement over simple unweighted least squares estimation on untransformed data suggests itself.

Background: Early marriages are at high risk of marital failure, poor family quality, young pregnancies at risk of maternal death, and the risk of being mentally ill to foster marriage and be responsible parents. Objective: To determine the effect of reproductive health education on peer groups (peers) on the knowledge and perceptions of adolescents about marriage age maturity. Method: This research uses the Quasi experimental method with One group pre and post test design, conducted from May to September 2018. The statistical analysis used in this study is a paired T test with a confidence level of 95% (α = 0, 05). Results: There is an average difference in the mean value of adolescent knowledge between the first and second measurements is 0.50 with a standard deviation of 1.922. The mean difference in mean scores of adolescent perceptions between the first and second measurements was 4.42 with a standard deviation of 9.611. Conclusion: There is a significant difference between adolescent knowledge on the pretest and posttest measurements with a value of P = 0.002, and there is a significant difference between adolescent perceptions on the pretest and posttest measurements with a value of p = 0.001. Increasing the number of facilities and facilities related to reproductive health education by peer groups (peers) in adolescents is carried out on an ongoing basis at school, in collaboration with local health workers as prevention of risky pregnancy.
