Technical Note—Dynamic Pricing and Demand Learning with Limited Price Experimentation
Authors: Cheung Wang Chi , Simchi-Levi David , Wang He
Published: August 2017

In a dynamic pricing problem where the demand function is not known a priori, price experimentation can be used as a demand learning tool. Existing literature usually assumes no constraint on price changes, but in practice, sellers often face business constraints that prevent them from conducting extensive experimentation. We consider a dynamic pricing model where the demand function is unknown but belongs to a known finite set. The seller is allowed to make at most m price changes during T periods. The objective is to minimize the worst-case regret—i.e., the expected total revenue loss compared with a clairvoyant who knows the demand distribution in advance. We demonstrate a pricing policy that incurs a regret of O(log(m) T), or m iterations of the logarithm. Furthermore, we describe an implementation of this pricing policy at Groupon, a large e-commerce marketplace for daily deals. The field study shows significant impact on revenue and bookings.

Screening Strategies for Patients on the Kidney Transplant Waiting List
Authors: Sabouri Alireza , Huh Woonghee Tim , Shechter Steven M.
Published: August 2017

Transplant centers screen patients on the kidney transplant waiting list to identify patients with severe conditions such as cardiovascular disease (CVD), which makes them ineligible for a transplant. We propose a model for finding screening strategies, with the objective of minimizing the sum of the expected screening cost and the expected penalty cost associated with transplanting an organ to an ineligible patient. Our results suggest that current screening guidelines, which are based only on patients’ risk for developing CVD, are significantly dominated by policies that also consider factors related to patients’ waiting time. In particular, our numerical experiments based on waiting list data in British Columbia show that compared with the current screening policy, our model-based policy results in a 35.6% reduction in the total annual cost by reducing the percentage of kidneys offered to patients with undetected CVD by 57.4% while using only 5% more screenings per year.

Developing and producing a focused conference poster
Authors: Dowling Sally , Albarran John
Published: August 2017

This fourth article in the Writing for Publication series aims to provide guidance on developing and producing a poster presentation for a conference. Most academic conferences offer opportunities for health professionals to present their work as an oral presentation or a poster; an earlier paper in this series discussed the submission of abstracts to conference organisers for consideration. Planning, preparing and producing a poster presentation requires different skills from those used when giving an oral presentation. These are examined in this paper by outlining what is meant by a poster presentation, and discussing key issues to consider when planning and producing a poster, and when presenting it at a conference.

Consenting to sexual activity
Authors: Griffith Richard
Published: August 2017

Engaging in sexual activity is an essential Human Right protected under article 12 of the European Convention on Human Rights ( Council of Europe, 1950 ) and should be free from state interference. District nurses, however, often express concern over the possibility that adults with acquired brain injury or a learning disability cannot give a real consent to participate in sexual activity and so should be prevented from doing so.

In this article Richard Griffith reviews the case law in relation to the capacity to consent to sexual activity.
Barriers to success: smoking cessation conversations
Authors: Kennedy Judith
Published: August 2017

Using the structure of Azjen's (1991) health behaviour model, this article examines the experience of promoting smoking cessation in a woman's booking appointment. Smoking cessation is a key contributor to adverse health outcomes, and is a priority for health professionals on a local and national scale. Conversations surrounding smoking cessation in pregnancy are often seen as difficult; midwives are often concerned they may harm the developing midwife-woman bond. The use of non confrontational brief intervention based methods may aid health professionals by creating a positive image of behaviour change. Barriers to the success of the intervention are discussed, including institutional pressures alongside ineffective communication skills, and suggestions for future practice are made. The importance of involving partners or family members in health promotion barriers to aid success is highlighted and demonstrates the wider impact midwives have on public health.
Continuity of carer and application of the Code: how student midwives can be agents of change
Authors: Corrigan Amy
Published: August 2017

Despite continuity of carer being signalled in policy in 1993 ( Department of Health, 1993 ), it remains a largely elusive aspiration in the UK. This has implications for midwives with regards to how well they can apply the Nursing and Midwifery Council (NMC) Code ( NMC, 2015 ) and their navigation of some of its inherent tensions. From the perspective of a new student midwife, this article discusses the advantages of caseloading in applying the Code and suggests ways in which student midwives might draw from the caseload model, bringing some of its strengths into mainstream practice.

Stroke assessment and management in pre-hospital settings
Authors: Sibson Lynda
Published: August 2017

This article will review the assessment and management of acute stroke in the pre-hospital setting. Stroke affects over 111,000 individuals per year, with almost 1 million individuals living with the after effects of stroke in England today. 85% of all strokes are ischaemic, treatments including with intravenous thrombolytic agents and mechanical thrombectomy, the remaining 15% haemorrhagic strokes are able to managed with decompressive hemicraniectomy. The key risks factors for stroke will also be briefly discussed, since they are commonly presenting conditions in the pre-hospital setting. A range of specific stroke assessment tools will be presented – not all are used, nor appropriate, for the pre-hospital setting – but it is useful to be aware of these. The article will also include differential diagnosis and stroke mimics. The key features of acute stroke are the sudden onset of focal neurological sings and symptoms.
Biology and reproductive traits of Drymoea veliterna (Druce, 1885) (Lepidoptera: Geometridae)
Authors: Hernandez Linda Carlina , Fajardo Gonzalo , Fuentes Luz Stella , Comoglio Lorenzo
Published: August 2017

Despite the urban and landscape impact caused by Drymoea veliterna (Druce, 1885) (Lepidoptera: Geometridae) larvae on trees of the genus Croton L. (Euphorbiaceae) in the Neotropics, there is no information about its biology and reproductive traits. In this study, we describe the life cycle and reproductive traits of this species. Its life cycle lasts approximately 56 days, the larvae develop during 24 days on average and the longevity of the females is 7 days on average. Females have an average fecundity of 207 eggs. Regarding their reproductive system, the presence of previtellogenic eggs in the reproductive tract of the females is emphasized. The bursa copulatrix and a highly sclerotized signum is depicted. The number of spermatophores found in the reproductive tract of the females was quantified. Male and female genitalia were schematized.
Anterior cruciate ligament reconstruction in skeletally immature patients
Authors: Longo U. G. , Ciuffreda M. , Casciaro C. , Mannering N. , Candela V. , Salvatore G. , Denaro V.
Published: August 2017

Aims

Different methods of anterior cruciate ligament (ACL) reconstruction have been described for skeletally immature patients before closure of the growth plates. However, the outcome and complications following this treatment remain unclear. The aim of this systematic review was to analyse the outcome and complications of different techniques which may be used for reconstruction of the ACL in these patients.

Materials and Methods

We performed a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. This involved a comprehensive search of PubMed, Medline, CINAHL, Cochrane, Embase and Google Scholar databases using the following combinations of keywords, “knee”, “anterior cruciate ligament”, “reconstruction”, “injury”, “children”, “adolescent”, “skeletally immature”, “open physis” and “surgery”.

Results

A total of 53 studies met the inclusion criteria and were included for analysis. The overall rate of disturbance of growth after ACL reconstruction was 2.6%, with no statistical difference between transphyseal and physeal-sparing techniques. Physeal-sparing techniques had a lower rate of post-operative complications compared with transphyseal techniques (p = 0.0045). Outcomes assessed were Lysholm score, International Knee Documentation Committee (IKDC) score, the IKDC grade, the Tegner score and the KT-1000. Both techniques had similar clinical outcomes.

Conclusions

This review reveals low rates of disturbance of growth after ACL reconstruction in skeletally immature patients. Although limited, the available evidence did not support any particular surgical technique when considering disturbance of growth or clinical outcome. Further randomised controlled trials are needed to investigate the efficacy of differing surgical techniques on outcomes in skeletally immature patients.

Plate fixationversusintramedullary nailing of completely displaced midshaft fractures of the clavicle
Authors: Fuglesang H. F. S. , Flugsrud G. B. , Randsborg P. H. , Oord P. , Benth J. Š. , Utvåg S. E.
Published: August 2017

Aims

This is a prospective randomised controlled trial comparing the functional outcomes of plate fixation and elastic stable intramedullary nailing (ESIN) of completely displaced mid-shaft fractures of the clavicle in the active adult population.

Patients and Methods

We prospectively recruited 123 patients and randomised them to either plate fixation or ESIN. Patients completed the Quick Disabilities of the Arm, Shoulder and Hand (DASH) score at one to six weeks post-operatively. They were followed up at six weeks, three and six months and one year with radiographs, and their clinical outcome was assessed using both the DASH and the Constant Score.

Results

Plate fixation provided a faster functional recovery during the first six months compared with ESIN, but there was no difference after one year. The duration of surgery was shorter for ESIN (mean 53.4 minutes, 22 to 120) than for plate fixation (mean 69.7 minutes, 35 to 106, p < 0.001). The recovery after ESIN was slower with increasing fracture comminution and with open reduction (p < 0.05).

Conclusion

Both methods return the patients to their pre-injury functional levels, but plate fixation has a faster recovery period in comminuted fractures than ESIN. ESIN has a shorter operative time and lower infection and implant rates of failure when using 2.5 mm nails or wider, suggesting that this is the preferred method in mid-shaft fractures with no comminution, whereas plate fixation is the superior method in comminuted fractures.

Authors: Brown T. S. , Van Citters D. W. , Berry D. J. , Abdel M. P.
Published: August 2017

Advances in polyethylene (PE) in total hip arthroplasty have led to interest and increased use of highly crosslinked PE (HXLPE) in total knee arthroplasty (TKA). Biomechanical data suggest improved wear characteristics for HXLPE inserts over conventional PE in TKA. Short-term results from registry data and few clinical trials are promising. Our aim is to present a review of the history of HXLPEs, the use of HXLPE inserts in TKA, concerns regarding potential mechanical complications, and a thorough review of the available biomechanical and clinical data.

Avascular necrosis in children with cerebral palsy after reconstructive hip surgery
Authors: Phillips L. , Hesketh K. , Schaeffer E. K. , Andrade J. , Farr J. , Mulpuri K.
Published: August 2017

Purpose

Progressive hip displacement is one of the most common orthopaedic pathologies in children with cerebral palsy (CP). Reconstructive hip surgery has become the standard treatment of care. Reported avascular necrosis (AVN) rates for hip reconstructive surgery in these patients vary widely in the literature. The purpose of this study is to identify the frequency and associated risk factors of AVN for reconstructive hip procedures.

Methods

A retrospective analysis was performed of 70 cases of reconstructive hip surgery in 47 children with CP, between 2009 and 2013. All 70 cases involved varus derotation osteotomy (VDRO), with 60% having combined VDRO and pelvic osteotomies (PO), and 21% requiring open reductions. Mean age at time of surgery was 8.82 years and 90% of patients were Gross Motor Function Classification System (GMFCS) 4 and 5. Radiographic dysplasia parameters were analysed at selected intervals, to a minimum of one year post-operatively. Severity of AVN was classified by Kruczynski's method. Bivar- iate statistical analysis was conducted using Chi-square test and Student's t-test.

Results

There were 19 (27%) noted cases of AVN, all radio- graphically identifiable within the first post-operative year. The majority of AVN cases (63%) were mild to moderate in severity. Pre-operative migration percentage (MP) (p = 0.0009) and post-operative change in MP (p = 0.002) were the most significant predictors of AVN. Other risk factors were: GMFCS level (p = 0.031), post-operative change in NSA (p = 0.02) and concomitant adductor tenotomy (0.028).

Conclusion

AVN was observed in 27% of patients. Severity of displacement correlates directly with AVN risk and we suggest that hip reconstruction, specifically VDRO, be performed early in the 'hip at risk' group to avoid this complication.
Silent landscapes, textured memory: Keith Morris Washington’s lynching paintings
Authors: Lloyd Christopher
Published: August 2017

Keith Morris Washington’s landscape paintings have received surprisingly little scholarly attention, and thus the present article aims to address that lack. Primarily, this article argues that in representing landscapes associated with lynchings, Washington’s paintings are a form of cultural memory that helps us apprehend the traumas of the southern past. Rather than presenting us with dead bodies of lynching victims, Washington paints the ‘texture’ of violence and memory in seemingly innocuous rural landscapes. Through his brushwork, framing and visual motifs, Washington reveals what I am calling the ‘after-burn’ of lynching: the way in which it circulates as a kind of haunting and memory that disturbs our gaze. While lynching scholarship has expanded in recent years, there is often a focus – as with other contemporary visual theories – on looking at lynching photographs; we are encouraged by a number of critics to apprehend death directly. This article suggests that Washington’s artwork provides us with another visual mode of apprehending lynching. In registering the texture of violence and memory, and through intimating the presence of corporeality, Washington enables a form of looking that does not re-victimize the victimized. Rather, his visual ethics allows us to both see and not see the deaths of (primarily) African Americans across the nation and region.
Sweet sick teens: Gothic narratives of American adolescent sexuality
Authors: Koehler Cara
Published: August 2017

Pivotal to the transition into adulthood is sexual maturation, an inescapable rite of passage which this article investigates across a range of contemporary American media. Beginning in the 1980s through the turn of the twenty-first century, the works in this archive tend to represent the increasingly politicized, stigmatized adolescent body as a conflict zone, a liminal precinct in which sex, illness and death often intersect to traumatic and Gothic effect. They consist of culturally influential ‘indie’ narratives that bridge the gap or, at times, blur the line between the mainstream and cult subculture. Starting from Victor Turner’s seminal work on the adolescent’s passage into adulthood, I place the concept of liminality side by side with the cultural imagination of the frontier. The sex and death dichotomy that characterizes adolescent sexuality shares with the fundamental trope of the frontier a wide array of Gothic connotations. Pre-existing scholarship on Gothic teen studies has yet to extrapolate on the portrayals of sickly teen bodies that run rampant in Gothic works. To append this missing link, I discuss Freudian drives, Susan Sontag’s illness metaphors, and Priscilla Wald’s readings of contagion narratives to lay the groundwork for the connection between sex, illness and cultural anxieties that these late-century narratives communicate. Indeed, I understand contemporary Gothic along the lines of Catherine Spooner, who quipped in her 2006 monograph that ‘[l]ike a malevolent virus, Gothic narratives have [...] spread across disciplinary boundaries to infect all kinds of media…’ (2006: 8). I consider sick teen bodies across a variety of works under two main headings: first, those that rely heavily on anaesthetized imagery to evoke the Gothic. Beginning with 2015’s genre-bending It Follows (Mitchell), I work backwards to trace its clear-cut intertext – The Virgin Suicides (Coppola, 1993), a teen dream-turned-nightmare likewise set in suburban Detroit. The second heading explores decidedly more violent works, among them the graphic novel Black Hole and the horror film Ginger Snaps (Fawcett, 2000), which juxtapose adolescence and supernatural monstrosities that act as carriers of disease. The female is often at the centre of the narratives at hand, and though these works explore the world of minors, rarely, problematically are ‘minority’ bodies represented. Common to these works are stigmatized figures who fight for individual expression yet often fail to emerge from the adolescent stage as autonomous adults, due either to their unwillingness to conform to mainstream culture or the failure of this culture to integrate them.

Increasing efficiency of a 33 MW OTEC in Indonesia using flat-plate solar collector for the seawater heater
Authors: Setiawan Iwan Rohman , Purnama Irwan , Halim Abdul
Published: August 2017

This paper presents a design concept of Ocean Thermal Energy Conversion (OTEC) plant built in Mamuju, West Sulawesi, with 33 MWe and 7.1% of the power capacity and efficiency, respectively. The generated electrical power and the efficiency of OTEC plant are enhanced by a simulation of a number of derived formulas. Enhancement of efficiency is performed by increasing the temperature of the warm seawater toward the evaporator from 26˚C up to 33.5˚C using a flat-plate solar collector. The simulation results show that by increasing these a water temperature up to 33.5˚C, the generated power will increase up to 144.155 MWe with the OTEC efficiency up to 9.54%, respectively. The required area of flat-plate solar collector to achieve the results is around 6.023 x 106 m2.
Design and implementation of hardware in the loop simulation for electric ducted fan rocket control system using 8-bit microcontroller and real-time open source middleware
Authors: Yulnandi Reza Aulia , Machbub Carmadi , Prihatmanto Ary Setijadi , Hidayat Egi Muhammad Idris
Published: August 2017

Hardware in the Loop Simulation (HILS) is intended to reduce time and development cost of control system design. HILS systems are mostly built by integrating both controller hardware and simulator software where the software is not an open source. Moreover, implementing HILS by using manufactured system is costly. This paper describes the design and implementation of HILS for Electric Ducted Fan (EDF) rocket by using open-source platform for development with middleware. This middleware system is used to bridge the data flow between controller hardware and simulator software. A low-cost ATMEGA 2560 8-bit microcontroller is used to calculate rocket’s attitude with Direction Cosine Matrix (DCM) algorithm and PID controller is employed to regulate rocket’s dynamics based on desired specifications. X-Plane 10 simulator software is used for generating simulated sensory data. The test results validate that HILS design meets the defined specifications, i.e. angle difference of 0.3 degrees and rise time of 0.149 seconds on pitch angle.

The Indian Ocean is influenced by monsoon systems which alter the ocean’s physical and chemical properties. Specifically, the southwestern Sumatran waters in the eastern Indian Ocean are considered a dual current regulated zone i.e. affected by South Equatorial Counter Current (SECC) and South Java Current (SJC). This area is considered as having an important role in the transfer of organic matter or the biological pump. However, the information about this area is minimal, especially in terms of organic matter and nutrient profile. This study will update the recent information about the area, including the profile of particulate organic matter (POM), macro-nutrients, total suspended solids (TSS), macromolecule-degradingbacteria, and soft bottom macrobenthic organisms sampled from 26 stations in both the SECC-regulated zone and the SJC-regulated zone. The physical profile is typical of tropical watersand both zones have a distinct profile of organic matter and nutrients. The particulate organic carbon (POC), particulate organic nitrogen (PON), and TSS of the SECC-regulated zone can be considered higher than those of the SJC-regulated zone. This region is categorized as mesotrophic waters, especially from the surface up to 100 m. The production of nutrients and organic matter in the water column in this area contribute significantly to the abundance of heterotrophic bacteria and benthic organisms.

A lo largo de las Jornadas de Discusión de la cátedra de Historia Americana II de la Universidad Nacional de La Plata (2011-2015) desarrollamos temáticas vinculadas a la historia cultural, prestando especial atención a la historia de las ideas, la literatura y las artes plásticas. Para el abordaje de dichos temas adoptamos una dinámica de taller, observando fuentes tales como revistas culturales, cuentos, poemas, manifiestos artísticos y obras pictóricas. Con el fin de planificar las Jornadas, pensamos que los objetos de estudio propios del historiador podían ser utilizados como un recurso didáctico original. Nos propusimos deconstruir los diferentes movimientos culturales, desde las representaciones propias de este espacio, definiendo qué era Latinoamérica para cada propuesta cultural, qué elementos la definían, y cómo era aprehendida la experiencia cultural internacional desde este lugar del mundo. A lo largo de los tres períodos, exploramos los significantes construidos en torno a esa porción de territorio y su relación con las posturas estéticas.

One of cases in islamic law today is same-sex marriage. The case sparked a controversy in muslim society. On theone hand, the case can be seen as an integral part of a person’s rights to meet the biological needs, but on the otherhand is seen as a violation of religious norms and moral principles. Those who have a sexual orientation towardsthe same gender (homosexual), which was also approved this orientation, continue to get same-sex marriagelegalization because a sense of love towards the same sex due to biological and psychological factors is viewed aspart of human rights. This paper attempts to examine same-sex marriage from the point of view of Islamic studies.[Salah satu kasus dalam hukum Islam saat ini adalah perkawinan sesama jenis. Kasus ini memicukontroversi.

Kajian ini difokuskan pada pembahasan terhadap mekanisme dalam usul fikih yang digunakan untuk melakukan penemuan dan juga perubahan hukum syariah, dengan referensi khusus terhadap salah satu problem yang dihadapi dunia Islam saat ini, yaitu masalah penanggalan. Penulis mengkaji tiga metode penemuan hukum dalam teori hukum Islam, yaitu metode bayani, metode kausasi, dan metode sinkronisasi dengan fokus pendalaman pada yang kedua dan memberikan contoh kasus keharaman rokok dalam beberapa fatwa kontemporer dan kasus penjatuhan talak di depan pengadilan seperti yang berlaku di Indonesia. Begitu pula penulis berpendapat bahwa ada empat syarat untuk suatu ketentuan hukum syariah dapat diubah dengan contoh kasus kebolehan perempuaan memangku jabatan publik seperti menjadi presiden yang secara harfiah nas dilarang. Lebih lanjut penulis menggunakan mekanisme tersebut untuk memecahkan problem penanggalan Islam dalam suatu perspektif global, dan menyimpulkan bahwa penanggalan Islam global tidak mungkin dibuat tanpa berpegang kepada hisab astronomi dan karenanya harus dilakukan reinterpretasi terhadap hadis-hadis rukyat dengan menggunakan mekanisme yang telah dijelaskan terdahulu

Indonesia is a nation in which the majority of its fellow citizens adhere to Islam. This furthermore stands as one of the reasons in creating judicial institution that specifically deals with Muslim judicial matters. Poligamy permit is an example of judicial matters subsumed under the jurisdiction of Religious [Islamic] Court. Despite of the fact that Islam recognizes polygamy, the intended person has to file polygamy permit to Islamic court for the sake of administrative order due to monogamy principle practiced within marital affairs. The Islamic court has the authority to look into the subjects involved in order to determine whether it is reasonable to grant the petition or not. This is however deployed to anticipate discrimination, right and responsibility abuses, and to reach verdicts that represent justice, utility, and legal certainty.

Interfaith marriage, in fact, is a contentious issue in the family law. The arrangement of interfaith marriage in Indonesia is experiencing a change since before and after the establishment of the constitutional Law of R.I. No. 1 of 1974 regarding Marriage. Although there are changes in the regulations but some parties consider that arrangement of interfaith marriage is not firm, it is unclear / smuggling law in it. Regulation of interfaith marriage in Indonesia is considered to have reduced the freedom to choose a mate and find the happiness with a partner of different religions. This is considered by the applicant that Article 2, paragraph 1 does not comply with the principle of freedom of human rights. This paper focuses on studying the problems of the interfaith marriages after a Constitutional Court decision No. 68 / PUU-XII / 2014 in the perspective of human rights. Constitutional Court rejected entirely about judicial interfaith marriage, as it is considered unreasonable under the law and marriage in Indonesia is based on religion. Constitutional Court's decision contains the values of human rights with a particular meaning and is limited by the limited freedom of religion in Pancasila and the 1945 Constitution.[Perkawinan beda agama secara fakta merupakan persoalan yang menjadi perdebatan dalam hukum keluarga.

Historically, the division of the estate had been there before Islam (pre-Islamic), The system is a system of descent and inheritance system of cause. The division of inheritance is patrilinear, meaning that children who are minors and women are not entitled to inheritance, even though they are the heirs of the deceased. Someone could get treasure if; their relative affinities, ties Prasetia appointments, and adoption. While in the early days of Islam one can get inheritance if; their relative affinity, adoption, their migration and their brotherhood. Inheritance, will happen if there are causes that bind the heir to the heir, as their marriage, kinship, and wala’. As for the things that can disqualify a person the right to receive an inheritance is; slavery, murder, different religion, an apostate, because disappeared without the news and different countries. Before the inheritance there are some rights that must be met first, as, rights relating to inheritance, maintenance costs corpse, repayment of debt and the provision of a will.[Dalam sejarahnya, pembagian harta warisan sudah ada sebelum Islam (pra-Islam). Adapun sistem pewarisannya adalah sistem keturunan dan sistem sebab. Pembagian harta warisan bersifat patrilinear, artinya anak-anak yang belum dewasa dan kaum perempuan tidak berhak mendapatkan harta warisan, sekalipun mereka merupakan ahli waris dari yang telah meninggal. Seseorang baru bisa mendapatkan harta apabila; adanya pertalian kerabat, janji ikatan prasetia, dan pengangkatan anak. Sementara pada masa awal Islam seseorang bisa mendapatkan harta warisan apabila; adanya pertalian kerabat, pengangkatan anak, adanya hijrah dan adanya persaudaraan. Pewarisan, baru terjadi jika ada sebab-sebab yang mengikat pewaris dengan ahli warisnya, seperti adanya perkawinan, kekerabatan, dan wala’. Adapun hal-hal yang dapat menggugurkan hak seseorang menerima warisan adalah; perbudakan, pembunuhan, berlainan agama, murtad, karena hilang tanpa berita dan berlainan negara. Sebelum pembagian warisan ada beberapa hak yang harus dipenuhi terlebih dahulu, seperti; hak yang berkaitan dengan zat harta peninggalan, biaya perawatan jenazah, pelunasan hutang dan pemberian wasiat]

The inclusion of environmental issues in formal education is recent. In this reality, the present study aimed to analyze the conception that teachers from public schools in São José do Egito, Pernambuco - Brazil, have on relevant issues and actions for Environmental Education. We interviewed 22 teachers through a structured questionnaire consisting of 10 questions focusing on environmental matters. We found that 95.5% of the interviewees showed interest in studying environmental issues and considered themselves as responsible for any environmental damage occurring. They all stated that environmental damage worries them and 72.7% have already tried to change this situation. They (72.7%) believe that there can be economic and social development without causing environmental impacts. Half of them consider the citizens as the main responsible for the damage to the environment and at the same time as the most involved with its protection. In addition, 40.9% said that the school where they work treats environmental issues superficially and 59.1% said the textbook as insufficient material to address environmental issues. The low school performance and the lack of teacher training in Environmental Education compromise the critical education of students regarding environment preservation.

O biodiesel tem sido destaque no mercado mundial de combustíveis por ser proveniente de material renovável e ser menos poluente quando comparado aos combustíveis derivados do petróleo. Sendo de origem animal ou vegetal, o biodiesel apresenta, também, as mesmas rotas de degradação que estas matérias-primas. Este trabalho foi desenvolvido com o objetivo de avaliar as propriedades químicas e físicas, a estabilidade oxidativa e armazenamento de biodiesel metílico de soja aditivado com e sem antioxidante. A influência dos parâmetros tempo e incidência de luz na qualidade do biodiesel foram avaliados a partir de caracterizações do índice de acidez, índice de peróxido, viscosidade cinemática e massa específica. Os resultados sugerem o melhor desempenho à estabilidade oxidativa ao biodiesel aditivado com 1000 mg.mL-1 de BHA, bem como as amostras que não foram submetidas à incidência de luz.

O compromisso de atender as necessidades do presente sem comprometer a possibilidade de suprir as necessidades das gerações futuras, torna a diversificação da matriz energética brasileira e mundial fator cada vez mais compulsório. Diante disso, o uso de biomassas lignocelulósicas para obtenção de combustíveis mais limpos do ponto de vista ambiental é amplamente discutido na atualidade. O etanol combustível pode ser obtido a partir de fontes alternativas de energia, como as biomassas lignocelulósicas. Esse tipo de matéria-prima possui elevado teor de açúcares fermentescíveis em sua composição. Porém, esses não se encontram diretamente disponíveis, sendo necessárias etapas adicionais para sua obtenção. Este trabalho teve como objetivo a otimização da etapa de pré-tratamento da palha de cana-de-açúcar, por meio de um delineamento experimental 22 com três repetições no ponto central. As variáveis de estudo foram: a razão palha/água (m/v) na etapa de pré-tratamento hidrotérmico e a temperatura reacional do pré-tratamento alcalino sequencial ao hidrotérmico. O estudo mostrou que a deslignificação não promoveu melhora significativa na conversão da celulose em glicose na hidrólise enzimática, o que não justifica a realização dessa etapa adicional, nas condições avaliadas. Já o pré-tratamento hidrotérmico apresentou bons resultados, alcançando na etapa de hidrólise conversões superiores a 85%, em especial para as razões palha/água 1:6,7 e 1:20 (m/v).

O uso de plantas medicinais no tratamento de enfermidades tem ocorrido há muitos anos, sendo a única terapia de certas comunidades. O Diabetes Mellitus é uma desordem metabólica caracterizada pela hiperglicemia, associada a outros fatores de risco. Este trabalho teve como finalidade realizar um levantamento de plantas medicinais utilizadas como hipoglicemiantes por usuários do Programa de Fitoterapia da Universidade Federal do Maranhão – UFMA, São Luís, Maranhão, Brasil. Foram entrevistadas 100 pessoas, através de questionários semiestruturados com obtenção de dados socioeconômicos e variáveis farmacobotânicas com listagem livre de plantas, aplicados entre os meses de março e junho de 2016. A maioria dos entrevistados era do sexo feminino (62%), com idade entre 30 e 59 anos (62%) e ensino médio completo (48%). Foram mencionadas 28 espécies vegetais com a finalidade hipoglicêmica, sendo a berinjela (Solanun melongena L.) a mais citada (31%). As folhas foram as partes da planta mais utilizadas (45%) e infusão foi a forma de preparo mais indicada pelos entrevistados (43%). O estudo das plantas realizado poderá auxiliar estudos posteriores no desenvolvimento de novos medicamentos para o tratamento de diabetes.

Published: August 2017

Este artigo visa verificar de forma inédita, por meio de um estudo explanatório, as possíveis correlações ainda não bem esclarecidas entre óbitos de dengue e fatores abióticos, como condições climatológicas e a influência da automedicação, para a cidade de Goiânia-GO. Para tanto, foram coletados dados governamentais destas variáveis entre 2005 e 2015 e para realizar uma aproximação multidimensional destes dados aplicou-se as Redes Neurais Artificiais (RNAs), na arquitetura Perceptron Multicamadas, otimizada pelo Algoritmo de Levenberg-Marquardt; realizando a construção e o estudo com seis topologias. Para obter a significância da correlação entre as variáveis de entrada da RNA foram propostas modificações do Método Profile. Os resultados mostraram que existe uma grande influência da automedicação e precipitação pluviométrica como principais impactantes nos óbitos, já a temperatura foi classificada com moderada significância. Dessa maneira, conclui-se que as RNAs podem ser aplicadas de forma satisfatória em problemas de modelagem epidemiológica.

Published: August 2017

Essa pesquisa objetivou avaliar a concentração de fenóis totais nas cascas do caule e folhas da mangabeira (Lafoensia replicata Pohl.), buscando uma correlação com a altura e circunferência do caule dos espécimes estudados. Dez indivíduos da planta foram selecionados em um fragmento de mata em Floriano, Piauí. Para a quantificação do teor de fenóis totais nas amostras foi utilizado o método Folin-Ciocalteu usando o ácido tânico como padrão. As quantidades de fenóis variaram nas cascas de L. replicata Pohl de 11,7 mg a 29,32 mg, variação menor que encontrada nas folhas, 2,60 mg a 33,70 mg. Não houve correlação entre os parâmetros biométricos e os teores de fenóis tanto nas cascas quanto nas folhas. Deve-se orientar a coleta dos recursos da planta para fins terapêuticos somente em indivíduos adultos para assim suportar os danos extrativistas.

Published: August 2017

The SEM and EDS results of porous coatings formed on pure titanium by Plasma Electrolytic Oxidation (Micro Arc Oxidation) under DC regime of voltage in the electrolytes containing of 500 g zinc nitrate Zn(NO3)2·6H2O in 1000 mL of concentrated phosphoric acid H3PO4 at three voltages, i.e. 450 V, 550 V, 650 V for 3 minutes, are presented. The PEO coatings with pores, which have different shapes and the diameters, consist mainly of phosphorus, titanium and zinc. The maximum of zinc-to-phosphorus (Zn/P) ratio was found for treatment at 650 V and it equals 0.43 (wt%) | 0.20 (at%), while the minimum of that coefficient was recorded for the voltage of 450 V and equaling 0.26 (wt%) | 0.12 (at%). Performed studies have shown a possible way to form the porous coatings enriched with zinc by Plasma Electrolytic Oxidation in electrolyte containing concentrated phosphoric acid H3PO4 with zinc nitrate Zn(NO3)2·6H2O.
