title: STATISTICAL CONTROL OF THE PROCESS APPLIED TO THE MONITORING OF THE WATER QUALITY INDEX

description: ABSTRACT Analyzing the physical-chemical and biological characteristics allows the evaluation of the water quality of a water body. Thus, the objective of this study was to determine the water quality index of the Passaúna and Piraquara rivers, as well as to apply statistical quality control methodologies to evaluate the data resulting from the monitoring of water quality. Therefore, a database with physico-chemical and microbiological parameters of the Passaúna and Piraquara rivers, a watershed of the Iguaçu River, belonging to the cities of Araucária and Piraquara, respectively Paraná, Brazil, was used to carry out the research. The water quality index was determined with the time series and, subsequently, these data were submitted to the statistical control of the process, with the control charts of individual Shewhart, EWMA and CUSUM, in addition to the development of the process capacity index. The WQI detected that the rivers remained in average quality until the year 2000, however, from that year it was possible to see a decreasing trend in the water quality of the evaluated rivers. The control charts of Shewhart, EWMA, CUSUM and the process capability index were able to identify the decreasing trend in water quality, demonstrating that they are fast and efficient techniques for the evaluation of water quality control.

title: Factors associated with microbiological and clinical cure of mastitis in dairy cows

description: ABSTRACT 709 clinical mastitis cases were analyzed and treated with antimicrobial combination cephalexin-neomycin and the anti-inflammatory prednisolone. A sample of milk was collected to perform a microbiological culture before starting the treatment and 14 days later. Somatic cell count (SCC) was obtained from samples collected on the day of the clinical case (D0), 14 days after (D14) and 28 days after (D28). Of the total, 435 (61.4%) at the D0 exhibited growth of microorganisms. Of the isolated agents, 365 (84%) were Gram-positive, and 66 (16%) were Gram-negative. A clinical cure was achieved in 63% of cases. Bacteriological cure occurred in 75% of cases. Only at D28 after the clinical case a significant SCC reduction was verified. The logistic regression for clinical cure showed significant effects for days in milk and parity (P&lt; 0.05). For bacteriological cure, there were significant effects of Log (SCC) D0; clinical cure and quarter affected (P&lt; 0.05). In the principal component analysis, the Temperature-Humidity Index was associated with reduced clinical cure of clinical mastitis cases.

title: A Reduced Semidefinite Programming Formulation for HA Assignment Problems in Sport Scheduling

description: ABSTRACT Home-Away Assignment problems are naturally considered as quadratic programming models in binary variables. For solving the problem, different formulations are studied here. First, the problem is rewritten as a quadratic programming formulation with linear constraints, and a quadratically constrained version respectively. For large scale problem, some reduced formulation are proposed by manipulating their special structure, with 1/4 of the original size. Note that the quadratic programming formulations lead to semidefinite relaxations solved approximately by semidefinite programming method. Comparison between our SDP relaxation and the MIN-RES-CUT based formulation is given. Finally some numerical experiments are given to illustrate the characteristics of each model.

title: Schizophrenia and violence: study in a general psychiatric hospital with HCR-20 and MOAS

description: Abstract Objective: This preliminary study aimed to identify and compare characteristics related to violent behavior in inpatients with schizophrenia at a general psychiatric hospital using the Historical, Clinical, and Risk Management 20 (HCR-20), the Modified Overt Aggression Scale (MOAS), and sociodemographic data. Method: Violent and nonviolent participants were selected based on psychiatric admission reports. Participants with reports of aggressive behavior and HCR-20 total score ≥ 21 upon admission were assigned to the violent patient group. Participants without aggressive behavior and with HCR-20 total score &lt; 21 upon admission were assigned to the nonviolent patient group. The MOAS was applied to characterize the degree of severity of the violent behavior. Results: HCR-20 and its subscales were effective in differentiating between the violent and nonviolent participant groups. Twelve of the 20 HCR-20 items were useful for distinguishing between the groups, although total HCR-20 scores were more reliable when applied to the nonviolent patient group. The MOAS did not show high degrees of severity for the types of aggression observed in the participants. Conclusion: HCR-20 was useful and reliable for distinguishing between violent and nonviolent patients with schizophrenia in this clinical psychiatric setting. Item analysis identified the most relevant characteristics in each group. The use of the HCR-20 in clinical psychiatric settings should be encouraged.

title: Locus of control among individuals with different pain conditions

description: Abstract: The objective of this study was to evaluate the psychometric properties of the Multidimensional Health Locus of Control – Form C (MHLC-C) scale applied to a sample of adult Brazilian patients with different pain conditions. The scores were then identified and compared on each of the subscales and profiles regarding locus of control. The sample consisted of 1,149 adult individuals (79% women; mean age: 36.6 years) of which 334 reported not feeling pain in the prior 24 hours, 386 reported pain in the prior three months, 250 reported recurring pain for the prior three months or longer, and 179 reported continuous pain for the prior three months or longer. A confirmatory factor analysis was performed. The invariance of the MHLC-C was tested on independent samples. The weighted global score was calculated for each of the factors and tested using ANOVA (α = 5%). Individuals were classified according to the eight health locus of control (HLC) profiles. The factors fit the data adequately after the model was refined. A higher score for the Health Professionals HLC was found among individuals reporting less than three months of pain. The “believer in control” profile was the most prevalent among the groups, while the least prevalent profile was the “pure chance” profile. The MHLC-C was found to be valid and reliable for assessing locus of control among people with different pain conditions. Only the Health Professionals HLC factor exhibited significantly different results for these individuals. The “believer in control” profile was the most prevalent among the pain conditions considered.

title: Geochemical signatures and weathering rates in soils derived from different granites in contrasting climatic locations

description: ABSTRACT. We studied the mineralogical properties and chemical composition of different granites using energy dispersive X-ray spectroscopy coupled with scanning electron microscopy to understand the relationship between granite signatures and soil characteristics, including weathering patterns and soil fertility status. The discriminant analysis (DA) was based on soil physical and chemical properties and was used to differentiate soils developed from I- and S-type granites across contrasting climatic conditions in northeast Brazil. The DA identified the highest values of organic carbon, clay and plant nutrients as key variables to recognize soil profiles derived from I-type granites. In contrast, the greater sand contents and Al saturation distinguished soils developed from S-type granites. These results were related to the mineralogical characteristics of each granite type, such as a high percentage of silica-bearing minerals in the S-type granites. The highest concentrations of K, Ca, Mg, and P in I-type granites were found in feldspars, amphiboles, and apatite. These elements account for the majority of nutrients derived in their soil profiles. However, it seems that the harsh conditions of the humid tropical environment equalized the effect of the rocks on weathering rates-the difference in chemical index of alteration is more extreme in the dry region.

title: Basic training of early childhood education teachers in written language and literature. The Universidad Autónoma de Barcelona - UAB case

description: ABSTRACT This article presents the results of a research performed in the Autonomous University of Barcelona (UAB) to evaluate the basic training in didactics of written language and literature for students of early childhood education. Through initial and final diagnostic tools and the contrast of data, it was found that this training channels the integration of the socio-constructivist principles of linguistic learning and the acquisition of both the foundations of literary education and a remarkable knowledge of books destined to first ages, as well as the application of key tools in the analysis and interpretation of both children's written productions and literary texts. All this results in a significant change of didactic projection. Despite this progress, the research also highlights the need to work more on the proactivity of children, the figure of the teacher as a mediator, contextualization of written language activities, interpretation of literary works and the definition of learning objectives in literature activities.

title: Occurrence of Mycoplasma bovigenitalium and Ureaplasma diversum in dairy cattle from to Pernambuco state, Brazil

description: ABSTRACT The objective of this study was to conduct an investigation of Mycoplasma bovigenitalium and Ureaplasma diversum infections in cattle in the microregion of the Ipanema Valley, state of Pernambuco, Brazil. Vaginal swabs were collected from 355 breeding cows in reproductive age and were analyzed by multiplex PCR (mPCR) and culture. An epidemiological investigation of risk factors was performed for Mollicutes. mPCR analysis showed that, 9.29% (33/355) of the cows were positive for M. bovigenitalium and 21.69% (77/355) for U. diversum; coinfection was observed in 2.81% (10/355) of the cows. The microbiological isolation showed, 81.81% (27/33) of Mycoplasma spp. and 24.67% (19/77) of Ureaplasma spp.. The risk factors related to Mollicutes infection identified were semi-intensive breeding system (OR= 4.6), pasture rent (OR= 3.6), non-isolation of animals with reproductive disorders (OR= 3.2), and natural mounting and artificial insemination (OR= 3.5). There was a significant association between Mollicutes infection and abortions in the first gestational third (P= 0.001). This is the first record of M. bovigenitalium and U. diversum infection in cows in the semiarid region of the state of Pernambuco, Brazil. Preventive measures directed to the identified risk factors can decrease the occurrence of Mollicutes in these herds.

title: Higher Order Markov Chain Model for Synthetic Generation of Daily Streamflows

description: ABSTRACT The aim of this study is to further investigate the two-state Markov chain model for synthetic generation of daily streamflows. The model presented in (4) to determine the state of the stream and later studied in (2) and (3) is based on two Markov chains, both of order one. In some areas of Hydrology, where Markov chains of order one have been successfully used to model events such as daily rainfall, researchers are concerned about the optimal order of the Markov chain (10). In this paper, an answer to a similar concern about the model developed in (4) is given using the Bayesian Information Criterion (BIC) to establish the order of the Markov chain which best fits the data. The methodology is applied to daily flow series from seven Brazilian sites. It is seen that the data generated using the optimal order are closer to the real data than when compared to the model proposed in (4) with the exception of two sites, which exhibit the shortest time series and are located in the driest regions.

title: Identification of subclinical mastitis caused by Mycoplasma spp. from screenings of bulk tanks

description: ABSTRACT Mastitis caused by Mycoplasma spp., regardless of species, are considered highly contagious pathogens and, usually was not responsive to antimicrobial therapy. Five dairy herds, comprising 489 animals and 1,956 mammary glands, were used in this study. Milk samples were obtained from bulk tanks and subjected to polymerase chain reaction (PCR) for the identification of Mollicutes, Mycoplasma spp., and Mycoplasma bovis. Moreover, individual samples from cases of clinical and subclinical mastitis in quarters of the dairy herds’ animals that yielded a positive PCR upon bulk tank analysis were subjected to molecular analysis. Only one bulk tank was positive for class Mollicutes by PCR. All positive samples classified as mastitis teats had their DNA extracted and tested by PCR for both class Mollicutes and M. bovis. Of these, two (2.08%) were positive for Mycoplasma genus, although none was positive for M. bovis. This result suggests that the PCR of bulk tanks is a viable tool in monitoring and preventing mastitis infections caused by Mycoplasma spp.
