Properties of degraded and reclaimed soils in the area of the abandoned “Jeziórko” sulfur mine (Poland)
Authors: Knap Renata , Kaniuczak Janina , Hajduk Edmund , Szewczyk Adam
Published: February 2017

The aim of the study was to determine some physicochemical and chemical properties of post-mining soils reclaimed in different directions, after completed sulfur exploitation by means of the borehole (Frash) method. The study was conducted in 2013 in the former Sulfur Mine „Jeziórko” located on the Tarnobrzeg Plain between Tarnobrzeg and Stalowa Wola cities (Podkarpackie Voivodeship, south Poland). It covered an area of land reclaimed as the arable or forest land. The most important problems connected with sulfur exploitation was the occurrence of a layer of solid sulfur which was previously removed. During the reclamation process, embankments and excavations were leveled through replenishing large amounts of ground, post-flotation lime, mineral fertilizers, and sewage sludge. Moreover, studies upon degraded and non-reclaimed area (by 2013) were also carried out. Examined land was characterized by granulometric composition of sands, loamy sands, and sandy loams. Re-leveling of degraded land using post-flotation lime contributed to lower levels of acidification of reclaimed soil surface. The highest contents of organic carbon and total nitrogen were found in the surface layers of the soils studied. Content of available potassium ranged from very low to average. The soils were characterized by a high content of available magnesium in the surface layers of the profiles (maximum 71.8 mg·kg−1 in soil reclaimed as forest land), while below the Mg content was usually low. Contents of individual exchangeable cations could be lined up in a following decreasing sequence: Ca2+>Na+>K+>Mg2+ Referring to the topsoil, reclaimed soils were characterized by more favorable properties (pH close to neutral, lower acidity, higher sorption capacity, higher organic carbon, total nitrogen, and available forms of phosphorus, potassium, and magnesium concentrations) as compared to non-reclaimed soil.
Method for determining iodine-127 in soils
Authors: Tołoczko Wojciech
Published: February 2017

A method was presented for determining the content of stable iodine-127 (127I) in soil samples. The method is based on the reaction rate of cerium cation (IV) with arsene (III) anion. The rate of this reaction is catalysed with the amount of iodide anions (I−) in a mineralised soil sample. The method is precise, with repeatable results, and it is ready for common application. The method was verified with the use of an analytical sample manufactured by POCH SA: TitraFix™ analytical sample of potassium iodateiodide 0.05 mol·dm−3I2(0.1N), (index: 743110161-020-1, tolerance range: ± 0.2%).
Simple Power Analysis Attack on the QC-LDPC McEliece Cryptosystem
Authors: Fabšič Tomáš , Gallo Ondrej , Hromada Viliam
Published: February 2017

It is known that a naive implementation of the decryption algorithm in the McEliece cryptosystem allows an attacker to recover the secret matrix P by measuring the power consumption. We demonstrate that a similar threat is present in the QC-LDPC variant of the McEliece cryptosystem. We consider a naive implementation of the decryption algorithm in the QC-LDPC McEliece cryptosystem. We demonstrate that this implementation leaks information about positions of ones in the secret matrix Q. We argue that this leakage allows an attacker to completely recover the matrix Q. In addition, we note that the quasi-cyclic nature of the matrix Q allows to accelerate the attack significantly.
Oblivious Lookup-Tables

Evaluating arbitrary functions on encrypted data is one of the holy grails of cryptography, with Fully Homomorphic Encryption (FHE) being probably the most prominent and powerful example. FHE, in its current state is, however, not efficient enough for practical applications. On the other hand, simple homomorphic and somewhat homomorphic approaches are not powerful enough to support arbitrary computations.

We propose a new approach towards a practicable system for evaluating functions on encrypted data. Our approach allows to chain an arbitrary number of computations, which makes it more powerful than existing efficient schemes. As with basic FHE we do not encrypt or in any way hide the function, that is evaluated on the encrypted data. It is, however, sufficient that the function description is known only to the evaluator. This situation arises in practice for software as a Software as a Service (SaaS)-scenarios, where an evaluator provides a function only known to him and the user wants to protect his data. Another application might be the analysis of sensitive data, such as medical records.

In this paper we restrict ourselves to functions with only one input parameter, which allow arbitrary transformations on encrypted data.
Modelling an Interactive Road Signs System, Using Petri Nets
Authors: Kombe Timothee , Ele Pierre , Offole Florence , Miasse Herman Olivier
Published: February 2017

This paper is a contribution to the problems of road insecurity in Africa. Due to non-respect of road sign and to the lack of signing, roads have become places of all dangers. It becomes imperative to establish an interaction between the authorities and the offending drivers. To reach this goal, we modelled an interactive road-vehicle-signage system, who locally informs the driver on the requirements of traffic signs. This model having interest only in the event of driving by bad weather or deterioration of panels, we are amending by inserting functions aimed to warn and punish the driver in the event of maintenance of an offense. Indeed, when the driver is about to commit a fault, firstly the system issues a warming (visual, audible or mechanical). Then, a message (SMS) is sent to the authorities. We include the concept of floating process engaged by devices other than the signage. We show that, with a few considerations, from the functional point of view, they are identical to the process engaged by the signage. Furthermore, in terms of performance, the model renewed warnings that occurred just before the end panel of prohibitions. It stores messages of offenses occurred without the network, then notifies them when a network is detected. We propose algorithms for incremental design and analysis of the model, whose processes are activated and / or are extinguished, according to the type of sign or tag encountered. We show by simulation and by linear algebra that, the model retains its properties of absence of blocking and boundedness during the evolution of the system, hence its validation.

Published: February 2017

Vibration tests are designed and executed for verifying the qualification of aerospace hardware. To accomplish this, a test fixture is required, to transmit mechanical energy from the shaker to the test specimen. This paper presents the experimental testing and finite element model correlation of an available vibration test fixture. The objective was to design an optimized fixture in which the first natural frequency was out of the test frequency range (5–2000 Hz). Many iterations of the test were performed, but the results are presented for only the few that contributed to the optimized design of the vibration test fixture. The final optimized design is presented and discussed.
Effect of Cooling Rate on Joint Shear Strength of Sn-9Zn Lead-Free Solder Alloy Reflowed on Copper Substrate
Authors: Tikale Sanjay , Sona Mrunali , Narayan Prabhu K.
Published: February 2017

Reliability of the solder joint largely depends on mechanical strength, fatigue resistance, coefficient of thermal expansion, and intermetallic compound formation. Cooling rate significantly affects the physical properties of an alloy and influences the mechanical behavior of solder joints. In the present study, Sn-9Zn lead-free solder alloy was solidified on Cu substrate under furnace cooling (0.04°C/s), air cooling (0.16°C/s), and water cooling (94°C/s) conditions. The effect of varying cooling rates on the intermetallic compound (IMC) formation at the interface and the resulting joint shear strength was studied. A microstructure study revealed the presence of Cu5Zn8 and CuZn5 intermetallic compounds at the solder-substrate interface. The IMC layer thickness at the interface increased with a decrease in the cooling rate. The joint shear strength increased with an increase in the cooling rate. The air and furnace cooling resulted in the formation of a thick IMC layer. The IMC obtained from the furnace cooling was associated with micro-cracks leading to a decrease in the joint shear strength.
On the Mesoscale Fracture Initiation Criterion of Heterogeneous Steels During Quenching
Authors: Said Schicchi D. , Caggiano A. , Lübben T. , Hunkel M. , Hoffmann F.
Published: February 2017

A numerical model aimed at investigating the microcracking behavior in steel meso-structures during quenching process is proposed in this work. The proposal explicitly considers the material heterogeneity influencing the fracture response of the steel meso-specimen under consideration. Particularly, a finite element based model is used in a two-stage simulation: (i) the first stage deals with solving the coupled metallo-thermo-mechanical problem at macroscopic level during quenching; (ii) the second stage accounts for the mesoscopic cracking based on a discontinuous approach by means of the extended finite element method. Different strain and stress histories have been used as failure (initation) criteria and have been compared with experimental results on high speed quenching of a 100Cr6 cylindrical (SAE 52100) steel specimen. The good agreement between the numerical simulations, adopting a maximum principal stress criterion as cracking initiation rule, and the experimental results indicates the potential of the presented methodology in the failure prediction.

Authors: Chander Pratibha , Kvalsvig Jane , Mellins Claude A. , Kauchali Shuaib , Arpadi Stephen M. , Taylor Myra , Knox Justin R. , Davidson Leslie L.
Published: February 2017

BACKGROUND:

Research in high-income countries has repeatedly demonstrated that intimate partner violence (IPV) experienced by women negatively affects the health and behavior of children in their care. However, there is little research on the topic in lower- and middle-income countries. The population-based Asenze Study gathered data on children and their caregivers in KwaZulu-Natal, South Africa. This data analysis explores the association of caregiver IPV on child behavior outcomes in children <12 years old and is the first such study in Africa.

METHODS:

This population-based study was set in 5 Zulu tribal areas characterized by poverty, food insecurity, unemployment, and a high HIV prevalence. The Asenze Study interviewed caregivers via validated measures of IPV, alcohol use, caregiver mental health difficulties, and child behavior disorders in their preschool children.

RESULTS:

Among the 980 caregivers assessed, 37% had experienced IPV from their current partner. Experience of partner violence (any, physical, or sexual) remained strongly associated with overall child behavior problems (odds ratio range: 2.46–3.10) even after age, HIV status, cohabitation with the partner, alcohol use, and posttraumatic stress disorder were accounted for.

CONCLUSIONS:

Childhood behavioral difficulties are associated with their caregiver’s experience of IPV in this population, even after other expected causes of child behavior difficulties are adjusted for. There is a need to investigate the longer-term impact of caregiver partner violence, particularly sexual IPV, on the health and well-being of vulnerable children in lower- and middle-income countries. Studies should also investigate whether preventing IPV reduces the occurrence of childhood behavior difficulties.

Published: February 2017

OBJECTIVE:

The few existing early-life obesity prevention initiatives have concentrated on nutrition and physical activity, with little examination of sleep.

METHODS:

This community-based, randomized controlled trial allocated 802 pregnant women (≥16 years, <34 weeks’ gestation) to: control, FAB (food, activity, and breastfeeding), sleep, or combination (both interventions) groups. All groups received standard well-child care. FAB participants received additional support (8 contacts) promoting breastfeeding, healthy eating, and physical activity (antenatal–18 months). Sleep participants received 2 sessions (antenatal, 3 weeks) targeting prevention of sleep problems, as well as a sleep treatment program if requested (6–24 months). Combination participants received both interventions (9 contacts). BMI was measured at 24 months by researchers blinded to group allocation, and secondary outcomes (diet, physical activity, sleep) were assessed by using a questionnaire or accelerometry at multiple time points.

RESULTS:

At 2 years, 686 women remained in the study (86%). No significant intervention effect was observed for BMI at 24 months (P = .086), but there was an overall group effect for the prevalence of obesity (P = .027). Exploratory analyses found a protective effect for obesity among those receiving the “sleep intervention” (sleep and combination compared with FAB and control: odds ratio, 0.54 [95% confidence interval, 0.35–0.82]). No effect was observed for the “FAB intervention” (FAB and combination compared with sleep and control: odds ratio, 1.20 [95% confidence interval, 0.80–1.81]).

CONCLUSIONS:

A well-developed food and activity intervention did not seem to affect children’s weight status. However, further research on more intensive or longer running sleep interventions is warranted.

Economy, safety and applicability of small modular reactors
Authors: Playbell Ioanna
Published: February 2017

Small modular reactors are a new generation of low-energy-output, low-hazard, compact and modular nuclear reactors, with an output of <300 MWe per unit. With the integration of inherent and passive safety measures, off-site construction and higher fuel burn-up rates, they promise a safer, lower-waste and reduced-risk venture, with earlier investment returns for investors compared with large-scale nuclear power plants. Moreover, non-proliferation is enhanced through the use of small quantities of non-weapons-grade nuclear fuel or the introduction of alternative potential fuels, such as thorium or fuel waste and actinides. This paper reviews the state of the art and discusses the economic feasibility of small modular reactors, with a focus on levelised cost of electricity, economy of scale and limitations for a country wishing to embark on nuclear energy through their deployment. Concerns regarding the integration of small modular reactors into the existing electrical grids of countries with various or no levels of nuclear-power production capability are also discussed. Suggestions on alternatively calculating the cost of small modular reactors and the legislation route are also provided, along with the pros and cons of the economics and safety of small modular reactor deployment in a country new to nuclear power.
Water migration in unsaturated partially hydrophobic soils
Authors: Orozco L. F. , Caicedo B.
Published: February 2017

This paper presents new insights into the effects of hydrophobic particles on water migration in fine-grained soils. The experimental set-up for this study uses columns of soil instrumented with sensors to measure the water content of soil during capillary rise, infiltration under imposed pressure and drainage. The soil was mixed with microparticles of Teflon (Polytetrafluoroethylene (PTFE)). The water retention curve was measured for mixtures with three different percentages of hydrophobic particles: 0, 2 and 5% by weight. Moreover, the water repulsion curve of the PTFE particles was measured using the water intrusion test. The results of this study show a significant effect of hydrophobic particles on capillary rise, but water repellency decreases when imposing a pressure. This study provides a new survey that could be useful for understanding the benefits and limitations of soil hydrophobisation.
Non-linear static behaviour of ancient free-standing stone columns

Published: February 2017

This work investigated the non-linear behaviour of ancient natural stone columns in the Mediterranean region made from multiple blocks or ‘drums’. A two-dimensional custom-made computational model based on the discrete-element method was employed. In the numerical model, the columns were represented as an assemblage of distinct blocks connected together by zero-thickness interfaces, which can open and/or close depending on the magnitude and direction of the stresses applied to them. Through non-linear static analysis, capacity curves and corresponding failure mechanisms of each of the studied models were obtained. The influence of different parameters (the number of drums, geometrical properties and imperfections at columns) was also assessed to observe their influence on the response of drum assemblies. The results of analyses revealed that rigid overturning is the main collapse mechanisms under uniform horizontal forces. A combination of rigid and shear failure mechanisms might also occur, depending on geometric characteristics and the choice of joint material properties. A higher displacement capacity was observed for columns constructed with a larger number of drums. It was also found that imperfections in the ancient free-standing columns have a significant influence on the lateral load resisting capacity. Therefore, structural analysis of undamaged columns may not represent the actual capacity of the columns due to their very sensitive and highly non-linear characteristics.

Az okos városok témája divatossá vált az utóbbi évek városfejlesztéssel foglalkozó nemzetközi konferenciáin, a nemzetközi tudományos szakirodalomban és a médiában is – főleg, amikor a városok jövőbeli fejlesztésről van szó – jelen van az okos város diskurzusa. A téma kutatásában három nagyobb szakterületről érkeznek kutatók: akik az okos városok technológiai infrastruktúrájával (telekommunikációs mérnökök, programozók), illetve a városok élhetőségével, ökológiai fenntarthatóságával foglalkoznak (ökológusok, környezetvédelmi szakemberek). A harmadik szakterület a különböző társadalomtudósok csoportja (szociológusok, regionális kutatók, geográfusok, közgazdászok), akik elsősorban az okos városok fejlesztésének társadalmi hatásait vizsgálják.A tanulmány első része a nemzetközi szakirodalom segítségével áttekintést nyújt az okosváros-koncepció értelmezéséről, történetéről és főbb jellemzőiről. Majd bemutatjuk azokat az alrendszereket, melyek az okos városok fejlesztésének kiemelt részterületei, illetve azokat a kapcsolódási lehetőségeket, melyekkel a területi kutatók és társadalomtudósok részt vesznek a téma jobb megismerésében. Végül a tanulmány utolsó részében arra keressük a választ, hogy a tér és társadalom összefüggéseit kutató szakemberek hogyan képzelik el a jövő okos városait. E kutatások fókuszában az „okos” világ áll, a „big data” típusú adatbázisok kezelésének területe, valamint az IT-cégekkel és programozókkal való együttműködési kapcsolatok építése.

A tér és térbeliség napjainkban sem játszik fontos szerepet a különféle szervezetek marketingtevékenységében. Tanulmányunkban – a térbeliség és a marketing alapfogalmainak áttekintését követően – bemutatjuk, hogy az üzleti gondolkodásban, a piacokról folyó diskurzusban, illetve ezen belül különösen a stratégiai marketingben mely területeken azonosíthatók térbeli problémák.A marketing térvonatkozásainak elméleti megalapozásához röviden ismertetjük a társadalmi térfogalom különféle megközelítéseit a társadalomtudományokban (regionális tudomány, társadalomföldrajz, közgazdaságtan, szociológia). A tér elméleti és alkalmazott közgazdaságtani értelmezését követően foglalkozunk a marketingre vonatkozó elképzelésekkel.Röviden bemutatjuk a marketing hazai és nemzetközi fogalmi megközelítéseit, és a marketing kotleri értelemben vett (tágan értelmezett) modelljét felhasználva emeljük ki annak explicit és implicit térvonatkozásait, rámutatunk a termék, az ár, az értékesítés és a kommunikációs stratégia térbeli sajátosságaira, a kapcsolati marketing, a társadalmilag felelős marketing és belső marketing területi aspektusaira. Számos példával illusztráljuk, hogy a marketing erőteljesen térbe ágyazott, így amellett érvelünk, hogy a hatékonyabb marketinggondolkodásban figyelembe kell venni a térbeli kapcsolódásokat, területi meghatározottságokat.A geomarketing-gondolkodásmódban, melynek szükségességére hívjuk fel a figyelmet, a térbeliség nem szűkül le a telephelyválasztásra és az értékesítéstervezésre, hanem áthatja a marketing egészét.
Retreat of the Cordillera Darwin icefield during Termination I
Authors: Hall B. L. , Denton G. , Lowell T. , Bromley G. R. M. , Putnam A. E.
Published: February 2017

During the last glaciation, the Cordillera Darwin icefield expanded northward toward the Straits of Magellan, eastward across Isla Grande de Tierra del Fuego and through Canal Beagle, and south and west across the numerous islands of southernmost Chile. Deglaciation commenced at ~18 ka during Termination I. Alpine glaciers in the Fuegian Andes also likely retreated at that time. Radiocarbon ages from the interior regions of Cordillera Darwin suggest ice in at least some locations had retreated close to its present-day limit as early as ~16.5 ka. The most likely cause for such rapid ice retreat was rising atmospheric temperatures at the start of Termination I.
Mass soil movement on terraced landscapes of the Mediterranean mountain areas: a case study of the Iberian Range, Spain
Authors: Arnáez J. , Lana-Renault N. , Ruiz-Flaño P. , Pascual N. , Lasanta T.
Published: February 2017

Terraces represent one of the most common agricultural landscapes in Mediterranean mountainous regions. However, the demographic and socioeconomic changes occurring in the second half of the last century caused terraces abandonment, leading to the loss of maintenance work required by these agricultural structures, and promoting various erosion processes, in particular the collapse of stone walls and small slides in risers. This paper analyses these mass movements by quantifying their size and frequency and defining the variables involved in their triggering in the upper valleys of Leza, Jubera and Cidacos rivers (Camero Viejo, Iberian Range, Spain), where bench terraces occupied 13,274 hectares (63% of agricultural space). A total amount of 240 small slides were recorded in 53 terraces studied, which means an average of 4.5 slides per plot and 33.1 m3 of material mobilized per 100 m of wall. This study proves that the most decisive causes for slides to start are related to soil infiltration capacity, as well as to the way in which water runs down the hillside.

Authors: Kapoor Gitanjali , Kumar Dinesh
Published: February 2017

Background: Sex ratio is defined as the number of females per thousand males. The objectives were to study the knowledge, attitude and the practice of pregnant women on gender preference, prenatal sex determination and female feticide.Methods: It was a hospital based cross-sectional study. The present study was undertaken among the 204 newly registered pregnant women attending the hospital in Marh block of Jammu district, Jammu and Kashmir, India. A pre-designed, pre-tested and structured questionnaire was used in the study. The data collection technique was a personnel interview of the study subjects.Results: The mean age of study subjects was 25.39±3.6 years. A majority (75.5%) of the pregnant women did not show any gender preference, followed by male preference (13.73%) and female preference (10.78%). Only 70.59% and 67.65%, of the total subjects were aware that prenatal sex determination and female feticide are illegal, respectively. Awareness regarding prenatal sex determination and female feticide increased with the level of education.Conclusions: There is a need to educate pregnant women about the impact of negative sex ratio on the society and about the penalization for violation of the PCPNDT act.

This study is done to compare the efficacy of pap smear cytology with lugol’s iodine guided cervical biopsy in detecting pre-malignant and malignant lesions of unhealthy cervix.Methods: The study comprises of 100 women aged between 18-65 years with clinically unhealthy cervix. They were subjected to pap smear, cervical punch biopsy, followed by visual inspection with lugol’s iodine (VILI). Sensitivity, specificity, positive predictive value and accuracy were calculated for pap smear and VILI using cervical biopsy as the standard diagnostic test.Results: Pap smear revealed that 64% had inflammatory smear and 17% had positive pap smear. On visual inspection of cervix with lugol’s iodine, 19 cases (19%) were VILI positive and 81 cases were VILI negative. Among 100 cases, 19 cases were biopsy positive and 81 cases were biopsy negative. Sensitivity of pap smear is 78.95% and specificity is 97.53%. Sensitivity of VILI is 94.74 and specificity is 98.77. For detecting all grades of CIN, VILI had an accuracy of 98%.Conclusions: Visual inspection with lugol’s iodine is more sensitive and accurate than pap smear. Screening of cancer cervix in low resource settings could be carried out by visual inspection of Lugol’s iodine (VILI) as it has good sensitivity and specificity. By combining pap smear with VILI and cervical biopsy, we can further maximize the sensitivity and specificity of cancer cervix screening.

Single Fetal Death in Monochorionic Twin Pregnancy: Co-Twin Prognosis and Neonatal Outcome
Authors: Vale-Fernandes Emídio , Dias Joana , Gil Belandina , Cadilhe Alexandra
Published: February 2017

The incidence of single fetal death in twin pregnancy varies from 0.5% - 6.8%, leaving the surviving fetus with increased morbi-mortality. The prognosis is worse in monochorionic pregnancies. In addressing these cases it should be noted referral to tertiary center with differentiated perinatal support, induction of fetal lung maturation and termination of pregnancy if there’s loss of fetal well-being or possibility of maternal complications and suspected neurological sequelae in the surviving fetus. The risk of iatrogenic prematurity should always be weighed with the possible consequences arising from the fetus staying in a hostile uterine environment. The authors describe a case of a 32-year-old pregnant woman with monochorionic/diamniotic twin pregnancy diagnosed with death of one of the fetuses due to fetal growth restriction and velamentous insertion of the umbilical cord at 30 weeks of gestation. The couple opted for termination of pregnancy at 33 weeks after documentation of brain changes in the surviving fetus.

O debate global sobre a política de investigação científica para a saúde humana tem sido liderado pela Organização Mundial da Saúde com contribuições importantes de outros stakeholders como o Council on Health Research for Development, o Banco Mundial e o Fórum Global para Investigação em Saúde, dominado recentemente pelas agendas temáticas de grandes financiadores globais. Existe um crescente interesse mundial em fazer melhor uso da evidência resultante da investigação científica para saúde, nas tomadas de decisão relacionadas com a definição de políticas de saúde. Na Europa verifica-se porém a existência de uma complexidade inerente à interação entre a investigação e a tomada de decisão política. Após cerca de 40 anos de democracia e 30 anos de integração europeia, Portugal superou o atraso científico estrutural. Contudo, a análise desta matéria à luz das políticas de investigação definidas a nível global e europeu mostra que há ainda um longo caminho a percorrer quando se fala em investimento global em Investigação & Desenvolvimento.

Em países com diversos níveis socioeconómicos, o assegurar dos cuidados de saúde requer a consideração de uma variedade de estratégias, nas quais pode incluir-se a prescrição não-médica. O objetivo desta revisão foi averiguar se a prescrição por profissionais de saúde não-médicos está associada a resultados (outcomes) clínicos e de relevância para o doente comparáveis à prescrição médica. Revisão sistemática de acordo com a metodologia preconizada pela Cochrane. Foram comparados os outcomes em saúde quando a prescrição médica era realizada por um qualquer profissional de saúde não médico (que prescrevesse com um alto grau de autonomia) versus por um médico, no contexto dos cuidados de saúde primários e secundários, e em países de baixo, médio e alto nível socioeconómico. Foram incluídos para análise 46 ensaios clínicos de diferentes desenhos que avaliaram um total de 37 337 indivíduos. A maioria dos estudos baseou-se na gestão da doença crónica em países de nível socioeconómico mais elevado, onde existe evidência que suporta que os outcomes são comparáveis para os marcadores substitutivos de controlo de doença relativos à hipertensão (evidência moderada), controlo de diabetes (evidência elevada) e hipercolesterolemia (evidência moderada), entre outros. A prescrição por enfermeiros e farmacêuticos com níveis variados de formação (pré-graduada, específica e pós-graduada) esteve também associada a outcomes globalmente comparáveis aos obtidos com a prescrição médica relativamente à adesão à medicação, eventos adversos, nível de satisfação global, qualidade de vida e utilização de recursos (hospitalizações, urgências hospitalares e consultas). Os prescritores não médicos frequentemente tiveram suporte médico disponível para facilitar um modelo de prática colaborativa. Com treino e suporte apropriados, a prescrição não-médica por enfermeiros e farmacêuticos é tão efetiva quanto a prescrição médica numa variedade de condições clínicas.
Discursive Political Analysis
Authors: Küçükali Can
Published: February 2017

This book introduces the reader to a new way of approaching political discourse which is called discursive political analysis (DPA). DPA takes the political realm as the kernel and conceptualizes political discourse as a functional tool which constantly modifies the agent’s position vis-à-vis structural factors to achieve or maintain political hegemony. DPA can be viewed as a complementary aspect of political analysis and addresses a wide audience who are interested in the functions and implementation of discursive strategies in politics. With its clear aims and focus, DPA helps researchers to comprehend the dynamic relation between political and discursive spheres by offering a practical framework for analysis.

Authors: Mittal Ashish
Published: February 2017

Corporate Disclosure can be defined as a process through which a business enterprise communicates with the external parties.  Disclosure is the movement of information from the private domain (inside information) into the public domain. To evaluate the disclosure level of various companies, some yardstick is required. A comprehensive list of 14 major items with breakup of 482 sub items has been made to determine the adequacy of disclosure practices of the corporate sector in India. Disclosure practices in selected 16 public sector companies at two points of time i.e. 1990-91 and 2006-07 has been divided into two sections i.e. Company wise analysis of Disclosure Score and Analysis of Major items of information. On the basis of Company wise analysis of Disclosure Score and Analysis of Major items of information , it can be concluded that there is considerable improvement in the various items disclosed by Private Sector companies over the period of study.
THE EFFECT OF DIET CONTAINING HIGH ALPHA-LINOLENIC ACID ON OMEGA-3 FATTY ACIDS AND HEALTH STATUS OF THE HEART IN BROILERS
Authors: Kartikasari Lilik Retna , Hughes Robert , Geier Mark , Gibson Robert
Published: February 2017

The objectives of the study were to examine the effect of diet high in alpha-linolenic acid (ALA) on omega-3 long chain polyunsaturated fatty acids (n-3 LCPUFA) and the health status of the heart. Diets were based on a commercial starter diet, with a low level of fat. The experimental diets contained two levels of ALA (2.23 and 19.37%), with the total fat content was approximately 5%. Pure or blended vegetable oils were included at a level of 2.8% in order to produce diets with the desired levels of linoleic acid (LA) and ALA. The ratio of LA to ALA of the diets  was  9.75:1 for control diet and 1.37:1 for high ALA diet. Each diet was provided ad libitum for the duration of the 28-d growth period. At 28 days of age, six selected birds from each pen (12 birds per group) were weighed individually and hearts were collected for analysis. A ratio of right ventricle mass (RV) to total ventricle mass (TV) was used to indicate the health status of the heart. Results showed that dietary treatment increased the level of ALA from 0.1% (control diet) to 0.5% (P<0.01). Increasing levels of dietary ALA raised the level of n-3 LCPUFA and total n-3 in heart tissues by 4-5-fold. There was no significant difference observed in the level of heart LA, arachidonic acid (AA) and total n-6. The increased levels of dietary ALA did not cause changes in the ratio of RV to total TV. In conclusion, it appears clear that based on our data, increasing ALA content in the diet of chickens could potentially be beneficial for the health of the birds; however, further work is necessary.

Abstract

Phosphorus deficiency is one of the most important yieldlimiting factor for maize growing in acid soil of tropical regions. 7he objective of this experiment was to screen maize (Zea mays L.) genotypes for P efficiency in culture solution. The experiment was arranged in a split plol design with three replications. The main plots were P fertilization i.e. 0 (without P), 1.4, 5, 10, 15, and 20 ppm of P, and the sub plots were 22 maize genotypes. The results indicated that both of AMATL- (HS)-C2 and BK-(HS1)-C2-55-1 were efficient in P absorption and utilization. BK-(HS1)-C2-113-1, SATP-1-(C2)-C6-S0, Bisma SATP-2-(S2)-C6-S0, and CML364 genotypes were efficient in P utilization. While BK-(HS)-C2-11-1, BK-(HS)- C2-129-1, AMATL-(S1)-C2-43-1, MRSS-1(S1)-C1-57-1 were efficient in P absorption.

Abstract

Study on a utilization of water birds species in Indramayu coastal area. West Java conducted in August to October 2002. It was recorded 8 species of water birds species during the study, of which the 2 species were migratory birds. Catching the water birds was a substitution job of the villagers to increase the income. Almost all of people at their productive ages catch the birds and sold it to the collector. Those birds can be fried and sold to the market as a food. Two species of water birds were the most popular to catch and consume by people, i.e. segrek/der (Gallirallus striatus), kuntul (Egretta intermedia). It’s necessary to control the catching activity by people, in order to guaranty sustainabe utilization of birds.

Abstrak

Studi pemanfaatan jenis burung air di pantai utara Indramayu, Jawa Barat dilakukan pada bulan Agustus-Oktober 2002. Berdasarkan hasil pengamatan di lapang tercatat delapan jenis burung air, di mana dua jenis di antaranya merupakan jenis burung migran. Kegiatan menjaring burung merupakan pekerjaan sampingan dari penduduk desa sekitar pantai utara Indramayu, yang pada umumnya bekerja sebagai petani, untuk menambah pendapatan keluarga. Hampir semua masyarakat desa dari kelas usia produktif melakukan kegiatan tersebut dan menjualnya ke penampung. Setelah daging burung digoreng, siap dikonsumsi oleh masyarakat. Dua jenis burung air yang populer dikonsumsi oleh masyarakat adalah segrek (Gallirallus striatus) dan kuntul (Egretta intermedia). Perlu upaya pengendalian aktivitas masyarakat dalam memanfaatkan potensi jenis burung tersebut, agar pemanfaatan sumber daya fauna tersebut dapat berlangsung secara berkelanjutan.
