Tobacco smoke exposure induces irreversible alteration of testicular function in prepubertal rats
Authors: Aprioku Jonah S. , Ugwu Theresa C.
Published: October 2016

Background:

Smoking is a serious public health problem and an important risk factor of many diseases. The present study evaluated whether or not the influence of prolonged tobacco smoke (TS) exposure on spermatic indices and reproductive hormones would be reversible in young and adult rats.

Methods:

Prepubertal and adult rats were grouped into five (I, II, III, IV, and V) separately (n=5/group) and exposed to TS at target concentrations of 0, 0.5, 1.0, 0.5, and 1.0 mg nicotine/day, respectively for 30 days using the whole body exposure inhalation method. Groups I, II, and III were sacrificed 24 h after TS exposure, while groups IV and V were allowed to recover for 30 days before they were sacrificed.

Results:

Sperm count and motility were significantly (p<0.05) reduced in exposed prepubertal and adult rats. Additionally, sperm morphology was unaltered, testosterone was reduced, while luteinizing hormone (LH) and follicle stimulating hormone (FSH) were elevated compared to the non-TS exposed control group. The reductions in sperm count and motility were reversed only in adult recovery rats. LH and FSH elevations were reversed in all recovery animals, but testosterone concentrations remained lower than control. Furthermore, malondialdehyde levels in testes of exposed rats were significantly increased. This was reversed only in adult recovery rats that received 0.5 mg nicotine. Testicular levels of catalase, reduced glutathione, and superoxide dismutase were unaltered, except in prepubertal rats wherein catalase was decreased in both treated and recovery groups.

Conclusions:

The TS exposure alters sperm characteristics reversibly in adult, but irreversibly in prepubertal rats, which is attributable to elevation of oxidative stress.
A Method of m-Point Sinusoidal Signal Amplitude Estimation
Authors: Sienkowski Sergiusz
Published: October 2016

The paper presents a new and original method of m-point estimation of sinusoidal signal amplitude. In this method, an m-point estimator is calculated on the basis of m initial signal samples. The way the estimator is constructed is explained. It is shown that the starting point for constructing the estimator is two initial signal samples. Next, in order to determine the estimator general form, three and m subsequent initial signal samples appearing in a signal period are used. Some special cases of an estimator are considered. Such an estimator is compared with a four-point estimator proposed by Vizireanu and Halunga. It is shown that the m-point estimator makes it possible to estimate the signal amplitude more accurately.
Comparison of silicon drift detectors made by Amptek and PNDetectors in application to the PHA system for W7-X
Authors: Krawczyk Natalia , Kaczmarczyk Jacek , Kubkowska Monika , Ryć Leszek
Published: October 2016

The paper presents comparison of two silicon drift detectors (SDD), one made by Amptek, USA, and the second one by PNDetector, Germany, which are considered for a soft X-ray diagnostic system for W7-X. The sensitive area of the first one is 7 mm2 × 450 μm and the second one is 10 mm2 × 450 μm. The first detector is cooled by a double-stage Peltier element, while the second detector is cooled by single-stage Peltier element. Each one is equipped with a field-effect transistor (FET). In the detector from Amptek, the FET is mounted separately, while in the detector from PNDetector, the FET is integrated on the chip. The nominal energy resolution given by the producers of the first and the second one is 136 eV@5.9 keV (at -50°C) and 132 eV@5.9 keV (at -20°C), respectively. Owing to many advantages, the investigated detectors are good candidates for soft X-ray measurements in magnetic confinement devices. They are suitable for soft X-ray diagnostics, like the pulse height analysis (PHA) system for the stellarator Wendelstein 7-X, which has been developed and manufactured at the Institute of Plasma Physics and Laser Microfusion (IPPLM), Warsaw, in collaboration with the Max Planck Institute for Plasma Physics (IPP), Greifswald. The diagnostic is important for the measurements of plasma electron temperature, impurities content, and possible suprathermal tails in the spectra. In order to choose the best type of detector, analysis of technical parameters and laboratory tests were done. Detailed studies show that the most suitable detector for the PHA diagnostics is the PNDetector.
Study on radiation-induced radicals giving rise to stable EPR signal suitable for the detection of irradiation in L-sorbose-containing fruits
Authors: Guzik Grzegorz P. , Stachowicz Wacław
Published: October 2016

The stable and complex EPR signals produced by the action of ionizing radiation on crystalline L-sorbose (C6H12O6) separated from rowan berries (Sorbus aucuparia) were studied. Isothermal heating of the samples at the temperature close to the melting point of L-sorbose (140°C) results in the modification and simplification of the EPR signal involved. In the EPR signal of heated L-sorbose, the isotropic quartet was distinguished. In the differential spectrum obtained by subtraction of normalized spectra of unheated and heated L-sorbose, the isotropic doublet was identified in addition. The DFT fitting offers the probable assignment of the EPR signals to specific radical structures.
Cognitive processing of verbal quantifiers in the context of affirmative and negative sentences: A Croatian study
Authors: Ćoso Bojana , Bogunović Irena
Published: October 2016

Studies from English and German have found differences in the processing of affirmative and negative sentences. However, little attention has been given to quantifiers that form negations. A picture-sentence verification task was used to investigate the processing of different types of quantifiers in Croatian: universal quantifiers in affirmative sentences (e.g. all), non-universal quantifiers in compositional negations (e.g. not all), null quantifiers in negative concord (e.g. none) and relative disproportionate quantifiers in both affirmative and negative sentences (e.g. some). The results showed that non-universal and null quantifiers, as well as negations were processed significantly slower compared to affirmative sentences, which is in line with previous findings supporting the two-step model. The results also confirmed that more complex tasks require a longer reaction time. A significant difference in the processing of same-polarity sentences with first-order quantifiers was observed: sentences with null quantifiers were processed faster and more accurately than sentences with disproportional and non-universal quantifiers. A difference in reaction time was also found in affirmatives with different quantifiers: sentences with universal quantifiers were processed significantly faster and more accurately compared to sentences with relative disproportionate quantifiers. These findings indicate that the processing of quantifiers follows after the processing of affirmative information. In the context of the two-step model, the processing of quantifiers occurs in the second step, along with negations.

Modlitwa wolności a kontyngencja człowieka w pamiętnikach Etty Hillesum
Authors: Mizdrak Inga
Published: October 2016

The experience of freedom, treated in various ways by philosophy, psychology, sociology, theology and politics, is shown as an infinite category. Its complexity and problematic matter is concerned not only with unlimited intellectual interpretations but also with the ways it is treated. From various ways of revealing the phenomenon of freedom, in the context of human contingency, the way of dialogue is prominent, which reveals one of the most important traits which freedom is.The original reflection, included in Etty Hillesum’s diaries (An Interrupted Life) reveals the basic feature of freedom: its relatedness, the deepest expression of which is achieved through one’s relationship with God. Through this feature, the trait of the human him- or herself is shown as he or she is able to direct him- or herself towards love or hate, life or death, beauty or ugliness, good or evil. Etty Hillesum herself is for life as it is, and she becomes the real ambassador of life through vertical relations with God, even in the face of extreme danger, injustice and the cruelty of war. In this context, life is not treated as the dominant and oppressive contingency but as a time of kairos, which means something that can be creatively and positively used to make human values and become a witness of life fulfilled by the element of eternity.In this light, the main goal of this study is to present a few basic threads of the description of humanity, as extracted from Hillesum’s self-reflective writing. By delving into the description of Hillesum’s inner world, an attempt is made to characterise those elements in the subjectivity of the human, which emphasises the specific individuum as being immersed in relations with himself, others and God.
“Women in groups can help each and learn from each other”: The role of homosocial practices within women’s social networks in building local gender contracts
Authors: Webster Natasha Alexandra , Caretta Martina Angela
Published: October 2016

Feminist scholars struggle to articulate gender relations in different contexts. Using the concept of local gender contract - a place specific agreement of gender relations, we explore how women’s networks challenge or shift gender contracts in their communities. Based on two empirical case studies of women´s groups from Eastern Africa and Thai migrants in Sweden, we show gender contracts are challenged through women’s homosocial activities. We highlight tensions between gender contracts and the women’s goals revealing a complicated process of assent and resistance. This study expands gender contract theoretically and provides a way to understand vulnerable women’s activities.
Seeking new paradigms in Aboriginal education research: methodological opportunities, challenges and aspirations
Authors: Shay Marnee
Published: October 2016

It is only relatively recently that Aboriginal peoples in Australia are represented in the academe, creating knowledges that speak for, and not of us. Internationally renowned Maori scholar, Professor Linda Tuhiwai Smith, was groundbreaking in her use of critical discourses needed for indigenous peoples globally to reclaim our knowledges and experiences through research. The emergence of Aboriginal and Torres Strait Islander scholars in Australia presents hope and opportunities for our communities to utilise the possibilities that ethical, Indigenous-driven research can have in interrogating complex and ongoing issues created by colonialism.Research that theorises Aboriginal epistemic and ontological research paradigms in Australia are still developing. Moreover, discipline-specific theoretical frameworks and methodologies are still emerging. This paper outlines my experience as an Aboriginal researcher in utilising Indigenist theoretical principles and methodological approaches. Using autobiographical reflections from my doctoral research, I present a range of practical implications that arise when the 'researched' shifts to the researcher in Western-dominated spaces such as schools. I will critically analyse the question, are Aboriginal researchers able to conduct research that is motivated by our agendas, ideas and aspirations in a discipline that perpetuates imperialism, racism and exclusion?

Authors: Serrano-Notivoli R. , Mora D. , Ollero A. , Sánchez-Fabre M. , Sanz P. , Saz M. Á.
Published: October 2016

Los ríos modifican la dinámica natural del ambiente fluvial y afecta enormemente a las áreas urbanas, especialmente en áreas de montaña donde las precipitaciones son frecuentes debido a las características de la precipitación y a la configuración orográfica. En este artículo se analiza la vulnerabilidad del sector central de los Pirineos a estos eventos, a través de un análisis de frecuencia de los datos de caudal y precipitación diarios desde 1940 hasta 2012 en las cabeceras de los ríos Aragón y Ésera. Se analiza también la evolución de los usos del suelo en los últimos 60 años. Los periodos de retorno muestran que las inundaciones no son excepcionales y que la frecuencia de caudales elevados es alta y estrechamente relacionada con los eventos de precipitación. Este hecho, combinado con un excepcional crecimiento de la ocupación humana de las áreas fluviales (especialmente desde la década de 1990) producida por la evolución de los usos del suelo desde 1956, ha aumentado el riesgo actual de exposición.

Authors: T. P. Shafeed , Paul Bijo
Published: October 2016

Background: Management of supracondylar fractures is a real challenge to the orthopaedician due to its extensive soft tissue injury, boneloss, comminution, articular extention and instability. Open reduction and internal fixation with anatomical distal femoral locking plate permits early mobilization. Stable anatomical fixation is necessary to avoid complications and disability.

Methods: 25 patients with Type A and Type C closed supracondylar femoral fractures were followed up from November 2013 to November 2015. All the patients underwent ORIF with DF-LCP. Clinical and radiological follow up were recorded for 24 months.

Results: Mean time for fracture union was 4.02 months. Average duration for full weight bearing was 122 days (range 90-180days). The average range of movement for Type A fractures was 105.71 degrees, for C fractures average ROM was 93.64 degrees. Average ROM for patients <50 was 103 degree and for patients>50 ROM was 98.66 degree.

Conclusions: Locked plating of DF fractures permits stable fixation and early mobilization which avoids disability and ensures good joint function.
When small RNAs become smaller: non - canonical functions of snoRNAs and their derivatives
Authors: Mleczko Anna Maria , Bąkowska-Żywicka Kamilla
Published: October 2016

Small nucleolar RNAs (snoRNAs) are molecules placed in the cell nucleolus and in Cajal bodies. Many scientific reports clearly show that snoRNAs are not only responsible for modifications of other RNAs but also possess multiple other functions such as metabolic stress regulation or modulation of alternative splicing. Full-length snoRNAs as well as small RNAs derived from snoRNAs have been implied in human diseases such as cancer or Prader – Willi Syndrome.  In this review we would like to describe these non – canonical roles of snoRNAs and their derivatives  with the emphasis on their role in human diseases.

Authors: Mallu Pratibha
Published: October 2016

It is customary in language classrooms to upgrade the teaching methods to make it more learner-centred. Students’ attention could be drawn easily towards language learning through the content. The main objective of the present study is, to suggest possible ways to introduce content-based instruction (CBI) for the development of communication skills of technical students. The content of CBI can be teacher presentations, video sequences, guest lecture talks, relevant newspapers articles, scholarly articles, essays, informative texts, etc. Using this content, teachers can conduct student presentations, discussions, JAM sessions, role plays, note taking, summarizing, etc. An ideal content-based instruction class gives equal importance to both content and language through conversations that encourage student language use and development. Taking information from different sources, re-evaluating and restructuring that information can help students to develop very valuable thinking skills that can then be transferred to other subjects. Thus, CBI can be motivating and rewarding.

THE GENOTYPES X ENVIRONMENT INTERACTION FOR STARCH YIELD IN NINE-MONTH OLD CASSAVA PROMISING CLONES
Authors: Sholihin Sholihin
Published: October 2016

Cassava (Manihot esculenta) is planted in dry areas with different environmental conditions, therefore the yield is varied. The aim of the study was to analyze the genotype x environment interaction for starch yield in 9-month old cassava promising clones. The experiment was conducted on mineral soils in four different locations, i.e. Lumajang-East Java (Inceptisols), Kediri-East Java (Entisols), Pati-Central Java (Alfisols), and Tulangbawang-Lampung (Ultisols) during 2004- 2005. The experiment was arranged in split plot design with three replications. The main plots were cultivation techniques, i.e. simple technology and improved technology, whereas the subplots were 15 cassava promising clones. Starch yield of 9- month old cassava plants was analysed using the additive main
effects and multiplicative interaction (AMMI). The results showed that environmental factors determined the stability of starch yield were soil bulk density on subsoil, the number of rainy days at fifth month, minimum air temperature at fourth month, and minimum air humidity at seventh month. CMM97002-183, Adira 4, CMM97007-145, CMM97007-235, Malang 2, CMM97002-36, and CMM97006-44 were identified as the stable cassava clones for starch yield in 9-month old. Average starch yield of Adira 4 was the third after MLG 10311 and CMM 97006-52. The CMM97006-52 was adapted to the soils having high P2O5 content on topsoil, high minimum air temperature at 4 and 5 months after planting, high minimum relative humidity at 7 months after planting, low total rainfall at 5 months after planting, and low number of rainy days at 5 and 8 months after planting. MLG 10311 was adapted to low soil bulk density. The average starch yield of MLG 10311 was the highest at 9 months after planting. The study implies that advanced trials for CMM 977006-52 and MLG 10311 clones are needed, so the clones can be released as new varieties of cassava. In selection and evaluation, the bulk density on subsoil is needed to be attained specifically to increase the probability to obtain new variety of cassava.

Tidal flats in the Musi Banyuasin region that cover more than 200,000 ha are the largest area for agricultural development in South Sumatra Province. Only about a half of this has been used for tidal swamp rice fields, therefore, the other half needs to be developed. To obtain a better understanding of their properties for appropriate soil management, soil characteristics of the area need to be studied. To characterize the soil, thirty-four soil samples from seven soil profiles were analyzed for their chemical and mineralogical composition at the laboratories of the Center for Soil and Agroclimate Research and Development. The results indicate that soils from the tidal flat areas have an aquic soil moisture regime, the upper parts of the soils are mostly ripe, and most of the pedons show the presence of sulfidic materials below 65 cm of the mineral soil surface. The soils are classified as Sulfic Endoaquept (P1, P2), Histic Sulfaquent (P3), Typic Sulfaquept (P4), Fluvaquentic Endoaquept (P5), and Sulfic Hydraquent (P6, P7). Mineral composition of the sand fraction is dominated by quartz, while the clay minerals consist of predominantly kaolinite, mixed with small amount of smectite, illite, quartz, and crystoballite. Organic carbon content is high to very high, potential phosphate content of most pedons ranges from very low to medium, while potential potassium content varies from very low to medium in the upper layers and medium to very high in the bottom layers. Phosphate retention of topsoil sample varies from 56 to 97%, and is positively correlated (r2 = 0.73) with aluminum from amorphous materials. Exchangeable cations are dominated by Mg cation, and in all pedons cation exchange capacity values are medium to very high, and seem to be influenced by organic carbon. Specific chemical properties, particularly soil pH and content of exchangeable aluminum exhibit a significant change about 1-2 months after soil samples were taken from the field. Theoretically, interaction between good water management and fertilizer application are among the choices of management to make these soils productive.

Farmers in the villages always face the same problem of how to reduce the moisture content of paddy harvest during harvest and postharvest time, especially in wet season. At the farm level, the grain quality is poor and alternative drying using kerosene fuel is very costly. The objective of this research was to design and evaluate the technical and economical  performance of drying paddy using an equipment known as "ABC" dryer.  The dryer uses paddy husk as fuel. The research was conducted at Research Institute for Rice over three years (1993/94-1995/96). The result showed that the "ABC" type dryer could reduce the moisture content of 5 tons wet paddy from 22.25% to 15.03% in 9 hours or an average drying rate of 1.05% moisture content per hour, with drying cost of Rp 18
kg-1. Reducing the moisture content further to 11.83% needed 16 hours or average drying rate 0.82% hour-1, with drying cost almost doubled (Rp 32 kg-1). These costs are far below that of kerosene drying, i.e., Rp 30 kg-1 and Rp 60 kg-1 to reach moisture content of 15.03% and 11.83%, respectively. Budget analysis showed that the B/C ratio were 1.57 and 1.84 and the IRR are above 41.26% and 47.42% to reach moisture contents
of 15.03% and 11.83%, respectively. The break even points of "ABC" dryer were 130 and 60 tons, respectively. The milling test showed that the milling rice from the "ABC" dryer had better recovery (milling rendement) and rice quality (head rice) was higher than that of from sun-drying.
COMMUNICATION APPROACH FOR AGRICULTURAL TECHNOLOGY TRANSFER IN VARIOUS AGRO-ECOSYSTEM ZONES: A Case Study in South Sumatra Province
Authors: Sulaiman Fawzia
Published: October 2016

An effective communication and dissemination of research results should be based on the natural resource endowment in each agro-ecosystem and the socio-economic background of the prospective clientele. The objective of this study was to examine several forms of communication approaches for disseminating agricultural technology and information. This study was based on a baseline survey conducted in four agroecosystems of South Sumatra Province, i.e. tidal swamp, swamp, dry lowland, and irrigated lowland. Results indicated that the social economic condition and natural resource endowment of farmers in the swamp agro-ecosystem zone (AEZ) of Ogan Komering Ilir is suitable for fishery development instead of food crop agribusiness. However, farmers in the swamp AEZ need technologies that reduce their workload in land cultivation and weeding activities. Further, as field extension workers (FEWs) were considered as the source of agricultural information by most farmers, the involvement of FEWs in agricultural research and technology assessment will increase the effectiveness of the innovation transfer, especially in the tidal swamp and irrigated lowland AEZs. In the four AEZs, the FEWs and farmer group leader can be used as an effective channel to convey agricultural technology and information in South Sumatra Province.

Megaloblastic anaemia, neural tube defects, coronary heart disease, and some forms of cancer have been linked to an inadequate dietary intake of folate. Legumes are good sources of folate, however, processing may affect folate availability in legume foods. This study investigated the folate content and retention during the preparation of tofu through the trienzyme treatment (protease, α-amylase, and human plasma) and microbiological assay using Lactobacillus casei. The results showed that the total folate content was considerably reduced during tofu preparation, from 273.4 µg 100 g-1 dwb in soybean seed to 108.4 µg 100 g-1 dwb in tofu, yielding a folate retention of 40%. Folate losses were mainly due to leaching into the water during soaking and pressing as well as heat destruction during milling and boiling. High folate loss (51%) was particularly found in the whey. A shorter soaking time (8 hours), optimum extraction, and pressing methods were suggested with respect to minimizing folate losses during tofu preparation. This study suggests that the consumption of 100 g of deep-fried tofu may satisfy 21% of the recommended dietary intake (RDI).
ESTIMATING SOYBEAN PRODUCTION EFFICIENCY IN IRRIGATED AREA OF BRANTAS RIVER BASIN

Published: October 2016

Soybean has an important role in Indonesian diet, especially as source of protein, fat, mineral, and vitamin. Given the relatively stagnant technology, efficiency improvement at farm level would probably be an appropriate way to increase soybean production in the near future. The objective of this paper was to estimate the technical efficiency of soybean production in irrigated area of Brantas river basin and analyze factors affecting technical inefficiency level. The results indicated that the technical efficiency of soybean production in the sites was around 83%. The analysis, however, failed to identify the determinants of technical inefficiency because none of the parameters in the analysis was significant. Further study is required to identify the determinants such that the target groups of extension can be specifically determined. Since K2O fertilizer significantly affected soybean production while P2O5 and N fertilizers did not, the first step to improve the technical efficiency of soybean production was to provide soybean farmers with recommendation regarding balanced amount of fertilizers. The recommendation, however, should be derived from local verification trial in each site.
