Andreas Frederik Beck’s Review of Kierkegaard’s On the Concept of Irony
Authors: Muench Paul
Published: August 2018

This article provides an English translation (with commentary) of Andreas Frederik Beck’s review of Kierkegaard’s On the Concept of Irony. Beck’s review is notable for its detailed, scholarly discussion of Kierkegaard’s text. While Beck draws attention to the unusual style of Kierkegaard’s dissertation and to Kierkegaard’s occasional use of irony, he does not treat the dissertation as itself ironic in overall form or intent. Kierkegaard’s response to this review, in which he makes the rare acknowledgement that Beck “has come quite close to having understood” him, provides indirect textual support for thinking that Beck is right in regarding Kierkegaard’s treatise on irony as a serious, scholarly work that is not itself essentially ironic.

Published: August 2018

The aim of the study was to isolate moderately halophilic bacteria that produce proteolytic enzymes with industrial biotechnological value. Screening of halophiles from various saline habitats, led to the isolation of 210 moderately halophilic bacteria producing industrially important hydrolases; such as proteases, which are enzymes that hydrolyze the peptide bonds of proteins, represent one of the three groups of industrial enzymes. The present study of halophilic bacteria, producing proteases and isolated from different saline soils of Sonora State, was divided in two parts: the first part included screening of moderately halophiles bacteria collected from various regions, while the second part consisted of enzyme production by fermentation in liquid medium in flask. Three strains of bacteria with potential proteolytic activity (BLRMAM1066, BLCLAM1064, PPSE3AM1053) were selected to continue the electrophoresis and zymogram tests, obtaining molecular weights from 19 to 193 kDa. One of the a priori objectives of this research is to have a collection of halophilic bacteria with high proteolytic activity
Value Perception of Information Sources in the Context of Learning
Authors: Raban Daphne Ruth , Rusho Yonit
Published: August 2018

Information sources require consumers to use them in order to evaluate their quality, meaning that they are experience goods. The value perceived before acquisition and use may be different from the value obtained by actual use. Understanding the value perception gap is likely to inform more efficient selection of information sources. The current research studies the value gap in a learning situation. We examine information value perceptions before and after experiencing information in an experiment with 113 software engineers engaged in a problem-based learning task while using and evaluating three types of information sources: supportive, reflective and reciprocal. The results indicate that before using an information source, the subjective value for supportive information is lower than for reflective information. In addition, 55% of the participants preferred to obtain information when presented with a choice. After using an information source no correlation was observed between perceived value of information before and after the use of information source (value gap); participants assigned a higher user experience (UX) value to reflective and reciprocal information than to supportive information; positive correlation between UX value and revealed information value; positive correlation between learning achievement and revealed information value; Reciprocal information is associated with higher learning achievement than reflective and supportive; use of information led to higher learning achievement than avoidance of information. Reciprocal information supports high achievement in software engineering informal learning. Reflective information is valued higher than supportive information sources. If supportive information is essential, learning environments designers should invest heavily in interface design combining reciprocal and reflective elements, such as forums and "try it yourself", respectively

Published: August 2018

Uterine sarcomas make up only 5% of all malignancies in gynecology. Their classification is complicated due to low incidence and large histological differences. Uterine sarcoma is usually diagnosed in postmenopausal women, and this is most often done accidentally at the postoperative stage. The existence of uterine sarcoma should be suspected in cases of rapid uterine growth in postmenopausal state. Postmenopausal abnormal bleeding is the most common reason for a medical examination.

In this paper, a 48-year-old patient is presented in whose case during a regular gynecological examination; the existence of tumour change in the uterine part of uterus has been noticed. The patient did not have gynecological problems until then. The patient was then subjected to a diagnostic exploratory curettage. The pathohistological finding was negative. Given that the onset change is present after the control check, it is decided to proceed with an operative procedure. A pathohistological finding (uterus and adnexa) indicates that it is a uterine sarcoma. After that, the patient was re-treated with two more operations and then had chemotherapy and radiation therapy. After completing the whole treatment, for the period of six years, the patient now feels well and performs her usual work tasks.
Clinical Implications of the Breast Cancer Susceptibility Genes BRCA1 and BRCA2
Authors: Narod Steven A
Published: August 2018

Genetic testing for BRCA1 and BRCA2 mutations has become an important part of the practice of medical oncology and clinical genetics over the past decade. Increasing numbers of women are requesting a genetic test so that they may better understand their personal risks of breast and ovarian cancer, and so that they may take appropriate measures to reduce the risk. Several of the risk factors can be modified, including breastfeeding and the use of oral contraceptives. A significant number of women opt for preventive mastectomy or oophorectomy, which will dramatically reduce the risks of breast and ovarian cancer. Chemoprevention with tamoxifen is still uncommon, largely due to women's fears of the side effects of the drug. A number of studies have shown that magnetic resonance imaging is superior to conventional mammography in terms of the early detection of breast cancer in the high-risk population. This article explores what is known about assessing genetic risk and the evidence supporting a range of preventive strategies.
Leukemia Risk after Adjuvant Treatment of Early Breast Cancer
Authors: Balduzzi Alessandra , Castiglione-Gertsch Monica
Published: August 2018

Modern cancer treatment has substantially increased the survival and curability of patients with various malignancies. Therefore, favorable prognosis mandates for the evaluation of long-term complications of treatment. Since the late 1970s, adjuvant combination chemotherapy for operable breast cancer has come into widespread use. Several recent studies have estimated the risk of acute myeloid leukemia associated with these regimens. The purpose of this analysis is to discuss the risk of leukemia after early breast cancer therapy, the types of leukemia, and the relationship between the risk of leukemia and treatment with different cytotoxic agents (alkylating agents, antimetabolities, topoisomerase II inhibitors, dose-dense therapy, high-dose therapy and growth factor use) and radiotherapy.
Hyperthyroidism During Pregnancy: Etiology, Diagnosis and Management
Authors: Lazarus John H
Published: August 2018

Pregnancy has marked effects on thyroid physiology and autoimmune thyroid disease tends to ameliorate through gestation due to the general immunosuppression seen in pregnancy. There is a need for trimester-specific thyroid hormone reference ranges. Hyperthyroidism in pregnancy – usually due to Graves' disease – is not common but, if the patient is compliant, a good outcome can be expected for both mother and child if treatment with anti-thyroid drugs (propylthiouracil is preferred) is instituted. Thyroid-stimulating hormone receptor antibody should be measured at 36 weeks in such patients in order to predict the possibility of neonatal hyperthyroidism. Transient gestational hyperthyroidism is often associated with hyperemesis gravidarum and thyroid function should be checked in patients severely affected by this condition. Radioiodine therapy is contraindicated in pregnancy but thyroid surgery may be performed safely in the second trimester. Autoimmune thyroiditis and Graves’ hyperthyroidism occur quite commonly in postpartum women.
Special Considerations in the Treatment of Pregnancy Rhinitis
Authors: Ellegård Eva K
Published: August 2018

Pregnancy rhinitis is a common condition that is not yet fully recognized by the public. This form of rhinitis affects approximately one in five pregnant women, can start in almost any gestational week, and disappears after delivery. However, as it reduces quality of life, and also possibly affects the fetus, treatment is often required. Saline irrigations, exercise and mechanical alar dilators are a safe and general means of relieving nasal congestion. Nasal corticosteroids have not been shown to be effective. As nasal decongestants provide good temporary relief, women tend to overuse them. Therefore, to avoid an additional rhinitis medicamentosa, nasal decongestants should be restricted to a few days use. Invasive methods of turbinate reduction may be effective, but are not recommended. The differential diagnosis towards sinusitis is often difficult. Antral irrigation is the ultimate diagnostic for purulent sinusitis and often needs to be repeated for therapeutic reasons. If β-lactam antibiotics are used, an increased dosage is required during pregnancy.

Authors: Tian Guo Hua , Lv Heng Lin , Huang Jian En , Liu Peng , Feng Wei
Published: August 2018

To enhance the thermal storage capacity of building envelopes and reduce the energy consumption associated with construction, a composite paraffin room temperature phase change ceramisite for a building envelope was developed. Based on a single factor test method, 52# paraffin and liquid paraffin were heated and melted together to prepare the composite phase change material, which was infiltrated into the ceramisite by vacuum adsorption. The ceramisite adsorbed with paraffin was encapsulated using acrylic emulsion, epoxy resin, or cement paste. The sand in the traditional ceramisite was replaced with the phase change ceramisite to prepare the phase change energy storage mortar for the building application. Using mercury porosimetry, differential scanning calorimetry, and thermal conductivity detection, the phase transition temperature, phase transition latent heat, encapsulation effectiveness, adsorption rate, coefficient of thermal conductivity, and specific heat capacity of the mortar were measured for the phase change ceramisite. The results indicated the following: the phase transition temperature of the composite paraffin could accommodate the range of indoor and outdoor thermal environments (18°C–35°C); a large amount of paraffin could be adsorbed into the ceramisite interior by vacuum adsorption, with the adsorption rate being higher than 58 %; with incorporation of the phase change ceramisite, the coefficient of thermal conductivity of the mortar gradually decreased and the specific heat capacity gradually increased; and when the ceramisite ratio reached 50 %, the coefficient of thermal conductivity decreased by 51.47 % and the specific heat capacity increased by 80.6 %, indicating favorable heat storage performance.
Effect of Jute Reinforcement Parameters on Mechanical Properties of Composite Structures
Authors: Gopinath P. , Suresh P.
Published: August 2018

In this study, yarn finenesses that are used in the fabric preform, fabric preform density, and preform laying angle were taken as the three important variables, and then the range of the process parameter was also selected based on the pilot run. These selected process parameters and their three different ranges were selected to conduct the experiments. In pure jute composites, the measured properties of tensile strength, flexural strength, and compression strength were very high in the plain-woven composites. This is ascertained through verification of experiments by producing a new sample. Through signal-to-noise ratio analysis, the research found that an optimum flexural value of 85.6822 MPa is obtained by maintaining the process parameter pattern as A1B1C1.
Bonding of Composite Panels via Silicone Adhesive in Rainscreen Facades
Authors: Kimberlain Jon H. , Dull Brent
Published: August 2018

The design and application of stone or metallic panels in panelized facade systems are well accepted and guided by industry practices in North America. Strong industry guidance provides for the selection and placement of mechanical fastening methods to secure these panels to a building. European countries have adopted similar systems but incorporate the use of adhesive methods of attachment, typically referred to as panel bonding applications. Trends both in the Americas and in Europe incorporate the use of composite panels consisting of man-made materials for panelized systems that fall outside the province of industry guidance for natural stone or metal industries. The lack of guidance leaves gaps in means or methods to reliably design and install a facade system using adhesive and composite materials. This paper sets forward an investigation to develop a framework for industry specification and standards for the use of large-format composite panels adhesively bonded using silicone adhesives. The investigation provides an overview of the available guidance and proposed methodology for the design and evaluation of adhesive systems drawing strong parallels to silicone structural glazing and mock-up evaluations of different systems for comparison. The investigation produced a methodology to adhesively attach panels using the developed framework and is presented to set robust design and fabrication principles for industry guidance development.
Automated Fatigue Testing Device for Assessing Performance of Sealant Jointing Products
Authors: Miyauchi Hiroyuki , Lacasse Michael A. , Ito Akihiko , Yamada Hitoshi
Published: August 2018

A description of the sealant jointing product test device is given herein that includes information on its operation and results from its use in subjecting sealant products to fatigue resistance tests. In the first instance, a novel benchtop sealant test device was developed that permits assessing the expected long-term performance of joint sealant products. This sealant test device can be used to conduct bench-scale testing indoors in a laboratory setting or outdoors whereby sealant products are exposed to weathering effects while undergoing movement. The device also includes a load cell that permits monitoring the load imposed on the products while undergoing movement; thus, changes in the resistance to movement can be monitored over time. Cyclic movement programs can be run once input to the device, and the rate of movement can be set at predetermined levels. In a subsequent development stage, the durability of sealed joints was verified with the use of the testing device. The effect of the curing condition and stress relaxation of sealants during joint movement were continuously monitored over the course of a daily cycle or a 12-s cycle of compression-tension with the device’s load cell. Results showed that over the curing period the sealant joint was damaged, as evident from changes in the cross-section of the sealed joint and reduction in stress of the jointing product. It is likely that this would influence the fatigue resistance of the sealed joint. In addition, in respect to the stress relaxation of sealants, the rate of decrease in the compressive load compared with the initial load is larger than that of the decrease on tensile load; as such, to properly evaluate the fatigue resistance of sealed joints, it is desirable to carry out a program of cyclic joint movement.
Fatigue Resistance of Rim Seals in Multi-Pane Glazing Systems from a Moisture Resistance Perspective: Solutions for Improving Moisture Barrier Performance
Authors: Ihara Takeshi , Yamamoto Masato
Published: August 2018

A technique widely used to mitigate climate change is the minimization of energy consumption in buildings by enhancing the thermal performance of glazing systems. Rim seals, consisting of a primary seal, secondary seal, and spacer, are the key to securing a good thermal performance because they protect the gaseous cavities of the multi-pane glazing systems, thus providing a long service life and good appearance. Fatigue due to wind pressure is a major aging factor for rim seals, and it deteriorates their moisture barrier performance. This study estimates the wind-inducing deflection of a 2-m-high double glazing system considering the wind strength and frequency of wind occurrence. A fatigue load was repeatedly applied to estimate the deflection movements in the rim seals. The results show that the repeated movements, which can be regarded as the accumulated fatigue damage over 25–50 years, increase the moisture permeability of the rim seals. A rim seal therefore can potentially lose its moisture barrier property with time. Our experimental results also provide a solution for reducing the change in the moisture permeability of the rim seals. A rim seal can exhibit stable moisture permeability after a fatigue test, when the boundary between the primary and secondary seals is not adhered. The lateral sides of the primary/secondary seals adjacent to the non-adhered boundary can move more freely (especially in a tensile condition) and independently than those adjacent to an adhered boundary and consequently may experience lower stresses. It is also important to design the section dimensions accurately. Thus, this study proposes a fundamental mechanism for maintaining a good moisture barrier property in rim seals. Further research is needed to investigate the stress distribution in different boundary conditions and the impact of other aging factors, such as heat and ultraviolet radiation.
Adhesive Bonding and Sealing of Additional Equipment on Foundations of Large-Scale Offshore Wind-Energy Turbines Withstanding Pile-Driving Operations
Authors: Wisner Gregor , Stein Philipp , Sychla Hauke , Kornemann Christian , Gattermann Jörg , Stammen Elisabeth , Dilger Klaus
Published: August 2018

Renewable energy is massively on the rise in different parts of the world, and offshore wind-energy farming is now competing for the first time with traditional power stations because of a basic continuity and amount of electrical energy. The relatively new kind of large-scale construction in the sea bed has to withstand the elements for decades, and the certification is based on a number of assumptions; therefore, wishes for changes or additional equipment on the foundations of offshore wind turbines do not comply with certification rules because thermally or mechanical interventions in the structure or the protection coatings might initiate an early damage scenario. Adhesive bonding of additional equipment on foundations is a solution for avoiding such certification problems, but this solution faces two major challenges: withstanding the initial-impact pile driving with huge mechanical accelerations and the more common long-term exposure to sea water, tidal and storm waves, and seasonal temperatures throughout the full lifetime period. Well-performing bonding and sealing over a long period of time presumes the successful survival of the initial high-energy impact pile driving without any damage, and this unique period of just a few hours with several thousand repeating blows can be seen as an enormous encroachment, especially for larger masses bonded to the pile walls. Suitable adhesives and coatings must show a special kind of durability for this initial operation. This paper presents experiences and results from experimental investigations of an adhesive bonding and sealing approach for installing measurement equipment on the vertical walls of different monopile foundations in offshore wind farms in the European North Sea.
Defining lipid mediators of insulin resistance: controversies and challenges
Authors: Metcalfe Louise K , Smith Greg C , Turner Nigel
Published: August 2018

Essential elements of all cells – lipids – play important roles in energy production, signalling and as structural components. Despite these critical functions, excessive availability and intracellular accumulation of lipid is now recognised as a major factor contributing to many human diseases, including obesity and diabetes. In the context of these metabolic disorders, ectopic deposition of lipid has been proposed to have deleterious effects on insulin action. While this relationship has been recognised for some time now, there is currently no unifying mechanism to explain how lipids precipitate the development of insulin resistance. This review summarises the evidence linking specific lipid molecules to the induction of insulin resistance, describing some of the current controversies and challenges for future studies in this field.

Authors: Yuan Weiming , Zhang Meibian , Zou Hua , Gao Xiangjing , Luan Yuqing
Published: August 2018

Objectives

Human brucellosis, as a zoonosis, is a serious public health problem in many developing countries, including China. To date, there has been no case report on occupational brucellosis and the emergency response in the pharmaceutical manufacturing industry. The aim of this report is to describe an emergency brucellosis outbreak in this unusual setting and the associated treatment methods from an occupational health perspective.

Methods

The emergency response included a field epidemiological investigation, a hierarchy of control strategy, and validation of control measures.

Results

Seven workers in the defrosting, grinding, and hydrolysis departments suffered from human brucellosis during two periods. The main symptoms were whole-body joint pain and undulant fever for several weeks, and Brucella-specific serum antibody was found in the patients. A hierarchy of exposure control strategy was implemented, including elimination, engineering control, administrative control, and the use of personal protection equipment. Raw material and environmental monitoring, measurement of placental temperature, Escherichia coli inactivation tests, and health examinations demonstrated that these measures were effective.

Conclusions

This report describes an emergent case and the response to two consecutive outbreaks of occupational brucellosis among workers in a pharmaceutical manufacturing enterprise. The hierarchical control strategy used in this case may prevent new outbreaks, and several lessons can be learned from this event.

Improving Hospital-to-Home Transitions for Children Entering Foster Care
Authors: DeLucia Michael , Martens Anna , Leyenaar JoAnna , Mallory Leah A.
Published: August 2018

BACKGROUND AND OBJECTIVES:

Hospital-to-home transitions present safety risks for patients. Children discharged with new foster caregivers may be especially vulnerable to poor discharge outcomes. With this study, our objective is to identify differences in discharge quality and outcomes for children discharged from the hospital with new foster caregivers compared with children discharged to their preadmission caregivers.

METHODS:

Pediatric patients discharged from the Barbara Bush Children’s Hospital at Maine Medical Center between January 2014 and May 2017 were eligible for inclusion in this retrospective cohort study. Chart review identified patients discharged with new foster caregivers. These patients were compared with a matched cohort of patients discharged with preadmission caregivers for 5 discharge quality process measures and 2 discharge outcomes.

RESULTS:

Fifty-six index cases and 165 matched patients were identified. Index cases had worse performance on 4 of 5 discharge process measures, with significantly lower use of discharge readiness checklists (75% vs 92%; P = .004) and teach-back education of discharge instructions for caregivers (63% vs 79%; P = .02). Index cases had twice the odds of misunderstandings needing clarification at the postdischarge call; this difference was not statistically significant (26% vs 13%; P = .07).

CONCLUSIONS:

Hospital-to-home transition quality measures were less often implemented for children discharged with new foster caregivers than for the cohort of patients discharged with preadmission caregivers. This may lead to increased morbidity, as suggested by more frequent caregiver misunderstandings. Better prospective identification of these patients and enhanced transition improvement efforts targeted at their new caregivers may be warranted.
Neonatal Hypotonia
Authors: Yozawitz Elissa , Delfiner Leslie , Moshé Solomon L.
Published: August 2018

Neonatal hypotonia represents a commonly encountered issue in the NICU and newborn nursery. Low tone is not a diagnosis in itself but, rather, a symptom. This review focuses on the special case of diffuse hypotonia presenting in the neonatal period. Etiologies are broad and include systemic illness, dysfunction of the central nervous system, or dysfunction of the peripheral nervous system and motor unit (ranging from disorders of the anterior horn cell to primary muscle disease). In this time of rapidly expanding therapeutic options for many diagnoses causing hypotonia, expeditious evaluation is crucial. Careful physical examination, thorough history, and appropriately selected ancillary testing guides the diagnostic process.
The Placenta and Neurodevelopment in Preterm Newborns
Authors: Garfinkle Jarred , Miller Steven P.
Published: August 2018

In caring for preterm neonates, a major challenge lies in understanding the contributors to brain dysmaturation and injury, both of which serve as precursors to childhood neurodevelopmental impairment. In addition to the various adverse exposures that the preterm newborn encounters in postnatal life, the placental antecedents of preterm delivery, in and of themselves, may affect brain dysmaturation and injury. The abnormal placenta is a frequent complication of pregnancy, and placental pathologies, such as placental insufficiency and acute chorioamnionitis, often precede preterm birth.

Placental insufficiency is the principal cause of fetal growth restriction and acts via chronic fetal hypoxia. During fetal hypoxia, cardiac output redistribution to the brain represents an important fetal adaptive response; however, vascular sparing of the brain does not ensure normal brain growth. Early fetal growth restriction, which is associated with a hypermature and malperfused placenta, results in neurodevelopmental impairment independent of the duration of gestation in preterm newborns. Acute chorioamnionitis is characterized by infiltration of the placenta by immune cells and often results from infection that induces an inflammatory response. Chorioamnionitis can lead to the fetal inflammatory response syndrome and preterm labor, and thus can add to subsequent neonatal brain injury. Placental health should be assessed in understanding the origins of preterm brain dysmaturation and injury, and subsequent neurodevelopmental impairment.
Monitoring urban greenness evolution using multitemporal Landsat imagery in the city of Erbil (Iraq)
Authors: Hussein Shwan O.
Published: August 2018

Most cities in the world have experienced major developments in the past 20–25 years. However, research has showed that the development aspect of these cities has led to a decrease in green areas. This paper aims to assess the spatiotemporal variations of urban green areas during the period 1990–2015 with special regard to city of Erbil. The study uses a mix of fuzzy functions, linear spectral mixture analysis, and maximum likelihood classification for the classification of Landsat imagery from 1990 to 2015 to extract the four main classes of land use, namely agricultural land, vacant land, built-up land, and green vegetation. Both the classification approaches used in this research produced excellent and reliable results, as an overall accuracy of more than 80% was able to be obtained. The spatiotemporal analysis of land use within the city of Erbil shows a series of major changes between 1990 and 2015. Therefore, the results of the spatiotemporal evolution of urban greenness assessment in the Erbil region can be used both for spatial planning purposes and as an urban greenness assessment method in dry climate areas.

TRES ARGUMENTOS KEPLERIANOS CONTRA EL UNIVERSO HOMOGÉNEO
Authors: Luna Francisco Javier
Published: August 2018

Este texto pretende analizar tres argumentos esgrimidos por Johannes Kepler en su polémica contra la cosmología de Giordano Bruno. Se ha considerado que existe una diferencia fundamental entre Bruno, quien hizo de la idea de un universo infinito la base de su filosofía natural, y Kepler, quien optó por un universo finito y concéntrico para su sistema astronómico. A pesar de que existen diferencias entre los dos autores mencionados, yo sostengo que también se dio un progresivo acercamiento de Kepler a algunas tesis de Bruno.

ABSTRACT Objective: To report the experience of the operationalization of clinical simulation as a pedagogical strategy in a subject of an undergraduate course in Nursing. Method: Clinical simulation cycles were carried out following the steps of action research, such as: planning, action, observation and reflection, from March 2014 to July 2015 with 10 professors and 44 students from a Primary Care and Mental Health subject of an undergraduate course in Nursing. Results: Five cycles of clinical simulation were performed, at the end of each cycle modifications were suggested by students and professors and the operation was adjusted to meet the needs of the subject. The main points of change were: professor role, logistics, equipment, debriefing model and preparation of “simulated patients”. Final considerations: The clinical simulation is a possible method to be operationalized in undergraduate course in Nursing, needs pedagogical and logistic planning as well as, sensitization of professors and students.

ABSTRACT Objective: To assess the quality of life and eating attitudes of health care students of the undergraduate programs of a public university. Method: Observational, cross-sectional, and quantitative study performed in a federal university. Three questionnaires were used for data collection: a socio-demographic and academic, the WHOQOL-BREF and the Eating Attitudes Test (EAT-26). Result: 399 students participated in this study, most women, average age of 22 years, average scores of EAT-26 of 15.12 and quality-of-life averages above 60 points in all domains. The students of the undergraduate program in Nutrition presented more inappropriate eating attitudes than other health care students; as the age evolves, vulnerability to inadequate eating attitudes increases; and the family income influenced negatively the quality of life in Physical and Social domains. Conclusions: Inadequate eating attitude diminishes the quality of life of health care students in all domains of the WHOOQOL-BREF.

Resumo Sintomas de depressão, ansiedade e estresse podem interferir negativamente no progresso do tratamento de usuários de substâncias. Este estudo objetivou avaliar os níveis de depressão, ansiedade e estresse em homens e mulheres em tratamento em Comunidades Terapêuticas, relacionando tais níveis com o tipo de substância utilizada e dados sociodemográficos. Utilizou-se um Questionário de Dados Sociodemográficos e de Uso de Drogas e a escala DASS-21. Participaram 115 homens e 53 mulheres, em tratamento, totalizando 168 indivíduos, com idade média de 32 anos (DP = 8,7). A maioria eram usuários de tabaco e crack, este último associado às mulheres. Identificou-se que os usuários de tabaco e os usuários de drogas que não tinham emprego se associaram a níveis mais altos dos sintomas de depressão, ansiedade e estresse. Conclui-se que tais estratégias podem auxiliar na diminuição dos sintomas avaliados pelo DASS-21, melhorando as condições de vida para o enfrentamento do transtorno por uso de substâncias.

Aplicação do Problema Restrito de Três Corpos no estudo do movimento de astros do sistema solar

Published: August 2018

Resumo Após uma revisão na literatura vimos que o Problema Restrito de Três Corpos (PRTC) é um tema com algumas publicações voltadas, principalmente, para a resolução do problema matemático, com muito poucas aplicações em situações reais e contextualizadas. Além disso, ao analisarmos alguns livros textos de mecânica clássica utilizados nos cursos de física, observamos que o PRTC não é desenvolvido e explorado didaticamente. Apoiados nessas análises o nosso objetivo neste trabalho é apresentar, desenvolver e aplicar o PRTC para simular as órbitas de dois astros do sistema solar: a do asteroide troiano da Terra, 2010 TK7, e a libração de Plutão devido a Netuno. Para resolver as equações diferencias do PRTC utilizamos o método de Cauchy em um código escrito na linguagem de programação Python. Nos dois casos estudados conseguimos verificar as trajetórias, valores e comportamentos orbitais dos astros. Por isso, entendemos que o PRTC pode ser aplicado para simular o movimento de diversos astros do sistema solar e, consequentemente, ser utilizado como um recurso pedagógico para contextualizar conceitos de mecânica celeste e dinâmica orbital. Uma vez que ele se relaciona com o estudo das equações diferencias, com a gravitação universal e com os métodos numéricos.

ABSTRACT The drift of hormonal effect herbicides is a major problem for agriculture, because, even in small amounts, it may cause high losses in crops with plants that are sensitive to their action mechanism. This study aimed to evaluate the efficiency of hydraulic spray nozzles with air induction, as well as the use of the LI-700 adjuvant, in the reduction of the 2,4-D herbicide drift, in tomato crop. A complete randomized split-plot experimental design, with eight replications, was used. Two herbicide solutions were assigned in the plots (with or without the use of adjuvant) [2,4-D (670 g ha-1) and 2,4-D (670 g ha-1) + LI-700 (712.88 g ha-1)], and, in the subplots, five nozzle models [simple fan (JSF11003), simple fan with air induction (AD-IA11003), dual fan with air induction (AD-IA/D11003), simple hammer fan with air induction (TTI11003-VP) and empty cone with air induction (CV-IA10003). The treatments were applied in a wind tunnel, under a pressure of 300 kPa. In a laser analyzer, applying only water, the volumetric median diameter, the relative amplitude and the percentage of drops with diameter lower than 150 µm were measured for all nozzle models. The CV-IA10003 and TTI11003-VP hydraulic nozzles outstand by reducing the 2,4-D herbicide drift and decreasing the damage to tomato plants. The addition of the LI-700 adjuvant to the 2,4-D syrup, independently of the nozzle model, reduces the drift of this herbicide and its effects on the tomato plant root. However, even when adopting these technologies, the application of the 2,4-D herbicide near the tomato crop should be avoided.
