Published: May 2014

O aço inoxidável AISI 444 tornou-se uma opção para substituir a liga AISI 316L devido ao seu menor custo e satisfatória resistência à corrosão. Entretanto, o uso da liga AISI 444 no feixe tubular de trocadores de calor acarreta na soldagem de uma junta dissimilar. O presente estudo teve por objetivo avaliar a resistência à corrosão da junta tubo-espelho soldada pelo processo TIG composta pelas ligas AISI 316L e AISI 444. A manufatura das amostras consistiu em replicar o projeto da junta tubo-espelho de trocadores de calor. Realizou-se em juntas soldadas ensaios de sensitização, perda de massa por imersão desde a temperatura ambiente até 90 ºC, e ensaios eletroquímicos de polarização potenciodinâmica nos eletrólitos 0,5 mol/L de HCl e 0,5 mol/L de H2SO4. Os resultados mostraram que a junta dissimilar sofreu corrosão galvânica com maior degradação na zona afetada pelo calor (ZAC) do tubo AISI 444. Porém, os mecanismos de corrosão localizada (pite e intergranular) demonstraram ser mais ativos para a liga AISI 316L. Conclui-se que a junta dissimilar apresentou melhor resistência à corrosão do que a junta soldada composta unicamente pela liga AISI 316L em temperaturas de até 70 ºC, conforme as condições observadas neste trabalho.

Published: May 2014

Neste trabalho estudou-se a perda de massa de revestimento duro aplicado pelo processo de soldagem com arame tubular com a variação de energia de soldagem, gás de proteção e número de camadas do revestimento. Com arame tubular autoprotegido de liga Fe-Cr-C-Ti foram depositados cordões sobrepostos na formação de camadas de revestimento sobre chapas de aço ao Carbono AISI 1020 para a análise da perda de massa, dureza, microestrutura. Foram realizadas medições de dureza na superfície dos corpos de prova de desgaste. Abrasômetro tipo roda de borracha foi usado para determinar a perda de massa dos revestimentos. Os revestimentos apresentaram microestrutura martensítica e austenita retida com carbonetos finamente dispersos na matriz. Os principais fatores que contribuíram para o aumento na perda de massa foram as trincas devido a maior taxa de resfriamento das amostras depositadas com baixa energia de soldagem, a diluição na primeira camada de todas as amostras também contribuiu para o aumento na perda de massa. As menores perdas de massa foram dos revestimentos de duas e quatro camadas depositados com alta energia de soldagem. A fração volumétrica de carbonetos de Titânio contribuiu para a diminuição do caminho livre médio entre as partículas de carbonetos aumentando a resistência ao desgaste dos revestimentos.

Published: May 2014

We compared the perceptions of Korean Americans, Koreans in the US, and Koreans in Korea, of the media coverage of the fatal shooting of 32 people at Virginia Polytechnic Institute and State University in April 2007. This comparison was based on the third-person effect, according to
which people perceive media coverage to have a greater influence on others than on themselves. Results showed that perception of individuals in the participant groups was that the media coverage had a greater influence on the Korean public in Korea (comparison group) than on themselves in
terms of generating negative feelings about Korean Americans and Americans (object groups). In addition, the more that Korean Americans perceived themselves to be similar to the Korean public in Korea, the more they overestimated the influence of the media on the Korean public in Korea.

Authors: Chiu Weisheng , Lee Kwang-Yong , Won Doyeon
Published: May 2014

We proposed and tested an extended model based on the theory of planned behavior to probe the mechanisms driving the purchase of counterfeit sporting goods (CSGs). Consumers (N = 333) in Taiwan completed surveys, and the results showed that subjective norms, perceived behavioral
control, and consumers' attitudes had a positive influence on purchase intention. In terms of extended variables, the results revealed no relationship between price-quality inference and consumers' attitudes, whereas risk averseness had a negative impact on consumers' attitudes. Differences
were also found between the Internet and street vendors as purchase channels. These findings open a new direction for understanding CSGs purchasing behavior.

Authors: Shi Laishun , Sun Meijie , Li Na , Zhang Bochen
Published: May 2014

A novel betaine type asphalt emulsifier 3-(N,N,N-dimethyl acetoxy ammonium
chloride)-2-hydroxypropyl laurate was synthesized after three steps by the
reaction of lauric acid, epichlorohydrin, dimethylamine and sodium
chloroacetate. The optimum reaction conditions were obtained for the
synthesis of the first step of 3-chloro-2-hydroxypropyl laurate. The
esterification yield reaches 97.1% at the optimum conditions of reaction
temperature 80?C, reaction time 6 h, feedstock mole ratio of epichlorohydrin
to lauric acid 1.5, mass ratio of catalyst to lauric acid 2%. The chemical
structure of the product was characterized by FTIR and 1H NMR. The first
synthesis step of 3-chloro-2-hydroxypropyl laurate was monitored by online
FTIR technique. The by-product was detected by the online FTIR analysis.
Based upon the experimental data, a plausible reaction mechanism was proposed
for the reaction. The CMC of the objective product has a lower value of
7.4?10-4 mol/L. The surface tension at CMC is 30.85 mN/m. The emulsifier is a
rapid-set asphalt emulsifier.

Published: May 2014

The effects of decaying leaf litter of Tithonia diversifolia and Vernonia
amygdalina as organic fertilizer, inorganic fertilizer (NPK 15-15-15) and
their combination effects on the growth and development of maize were studied
in a screen house. Twenty-four experimental bags filled with 20 kg of loamy
soil were laid out in a completely randomized design with six treatments and
four replications for each treatment which included: 250 g of decaying leaves
of T. diversifolia as mulch (T1), 250 g of decaying leaves of V. amygdalina
(T2), 1.52 g of NPK (inorganic) fertilizer (T3), a mixture of 250 g of
decaying leaves of T. diversifolia and 1.52 g of NPK 15-15-15 fertilizer
(T4), a mixture of V. amygdalina and 1.52 g of NPK 15-15-15 fertilizer (T5)
and control (T6). The significant growth as well as maize yields were
obtained from T3 treated maize seedlings, and this was closely followed by T4
treated seedlings. The study showed that the decaying leaf litter as an
organic fertilizer in maize production in a screen house conditions did not
give better yield than NPK treatment alone.

Published: May 2014

The aim of this study was to evaluate the chemical composition of the back
fat tissue of mangalitsa pig and meaty pig breeds and their crosses, and the
pigs that were fed with feed that was enriched or unenriched with oil, from
the aspect of the production of biodiesel, where the starting material for
the fuel would be the fat tissue of pigs. By examining the impact of breed
and oil content in feed, it was found that chemical parameters (fat, water,
protein, saturated and unsaturated fatty acids) show statistically
significant variation under the influence of these factors. The highest fat
content (89.39%), which is essential for conversion of fat into biodiesel,
was found in back adipose tissue of mangalitsa breed, while the lowest fat
content (86.10%) was found in the back fat tissue of meaty breeds and their
crosses. Favorable ratio of saturated to unsaturated fatty acids (37.92% :
62.07%), on which some physical properties of the fuel depend, was found in
the back fat tissue of pigs that were fed with feed enriched with oil, and
the largest proportion of saturated fatty acids, i.e. the most unfavorable
fatty acid composition (40.90% : 59.09%) was found in the back fat tissues of
pigs that were fed with feed unenriched with oil. The lowest content of
saturated fatty acids and water (7.44%), as the key factors that determine
the cetane number of the fuel and the fuel production process, indicates that
the most suitable raw material for the production of biodiesel is the fat
tissue of pigs that were fed with food that contained a certain amount of
oil.
Rural livelihood diversification and income inequality in local government area Akinyele, Ibadan, Oyo state, Nigeria
Authors: Adepoju Abimbola , Oyewole Olaniyi
Published: May 2014

The pattern of income distribution has been a major concern in the developing
world. This is because high levels of income inequality are likely to create
a hostile atmosphere for economic growth and development. This study examined
rural livelihood strategies and their contribution to the overall income
inequality of households in Akinyele local government area of Oyo state.
Primary data employed in the study were obtained from 105 respondents
selected through a multi-stage sampling technique. Data were analyzed using
descriptive statistics, multinomial logit and the generalized entropy
inequality indices as a measure of inequality. The distribution of
respondents by type of livelihood strategy adopted revealed that almost half
of the respondents adopted the combination of farm and non-farm strategy
while 14.3% and 40.0% adopted only farm and non-farm strategy respectively.
Income inequality was the highest among non-farming households and the lowest
among farming households, implying that income from non-farm activities
contributed most to income inequality in the study area. The study revealed
that the major factor which negatively influenced the choice of farming as a
livelihood strategy was household size while factors such as age and land
ownership had positive and negative effects on the adoption of the non-farm
strategy respectively. The study recommends that policies targeted at rural
dwellers should centre on improved access to productive assets such as land
for the landless farmers as well as the provision of improved technology,
which could encourage the ageing farming population to engage in farming
activities.
Albian ammonites from northern Pakistan
Authors: Kennedy William James , Fatmi Ali N.
Published: May 2014

The occurrence of rich Albian ammonite faunas in what is now northern Pakistan has been known for more than 80 years, but there has been no comprehensive account of the assemblages present. A total of 36 taxa are described below. The middle part of the Lumshiwal Formation yields Upper Aptian ammonites south of the Samana Range. Elsewhere, it yields Douvilleiceras leightonense Casey, 1962, of the lower Lower Albian Leymeriella regularis Zone and the Sonneratia perinflata and S. kitchini Subzones of the Sonneratia chalensis Zone of the northwest European sequence. The top one to two metres of the Lumshiwal yields an abundant fauna of rolled and phosphatised ammonites that includes elements from much of the Albian. Of these, Prolyelliceras gevreyi (Jacob, 1907) first appears in the lower Lower Albian Leymeriella tardefurcata Zone. The commonest ammonite is Douvilleiceras mammillatum (Schlotheim, 1813) sensu lato, which ranges from the perinflata Subzone of the chalensis Zone to the Otohoplites bulliensis Subzone of the O. auritiformis Zone of the Lower Albian. The presence of Lyelliceras pseudolyelli (Parona and Bonarelli, 1897) indicates the uppermost, pseudolyelli Subzone of the auritiformis Zone. The presence of Lyelliceras lyelli (d’Orbigny, 1841) indicates the basal Middle Albian lyelli Subzone of the Hoplites dentatus Zone. There is no evidence for the higher parts of the Middle Albian. Dipoloceras (Rhytidoceras ) sp. indicates the presence of lower Upper Albian, possibly the pricei Zone. There is evidence, in the form of specifically indeterminate Mortoniceras (Mortoniceras) sp., of a level within the inflatum to fallax Zone inteval from a single locality, but no evidence of the succeeding parts of the upper Upper Albian. The base of the Kawagarth Formation that succeeds the Lumshiwal yields lower Upper Albian Mortoniceras (M.) geometricum Spath, 1932 of the Mortoniceras pricei Zone, northwest of Darmasand in the Samana range.

Effects of plant growth-promoting rhizobacterium (PGPR) and arbuscular mycorrhizal fungus (AMF) on antioxidant enzyme activities in salt-stressed bean (phaseolus vulgaris l.)
Authors: Younesi Omid , Moradi Ali
Published: May 2014

Plant Growth-Promoting Rhizobacterium (PGPR) represents a wide variety of soil bacteria that, when grown in association with a host plant, result in stimulation of growth of their host. The aim of this study was to investigate the influence of inoculation with a PGPR, Pseudomonas fluorescence, alone or in combination with an arbuscular mycorrhizal fungus, Glomus mosseae (Nicol. & Gerd.), on antioxidant enzyme activities (catalase (CAT) and peroxidase (POX)), phosphatase activity, solutes accumulation, growth and minerals nutrient uptake in shoots of bean (Phaseolus vulgaris L.) affected by three levels of salt stress. Salinity decreased bean growth, regardless of the biological treatment and the salt stress level. The plants inoculated with P. fluorescence had significantly greater shoot biomass than the control plants at all salinity levels, whereas the mycorrhizal inoculation treatments were only effective in increasing shoot biomass at a low salinity level. The plants inoculated with P. fluorescence presented higher concentrations of shoots’ K+ and lower concentrations of shoots’ Na+ under high salt conditions. Salt stress increased shoots’ proline concentration, particularly in plants inoculated with the PGPR. Increasing salinity stress raised significantly the antioxidant enzyme activities, including those of total POX and CAT, of bean shoots compared with their corresponding nonstressed plants. The PGPR strain induced a higher increase in these antioxidant enzymes in response to severe salinity. Inoculation with selected PGPR could serve as a useful tool for alleviating salinity stress in salt-sensitive plants.

Authors: Lazăr Alexandra , Szederjesi J , Copotoiu Ruxandra , Copotoiu Sanda-Maria , Azamfirei L
Published: May 2014

Objective: The aim of this study was to evaluate the clinical utility of Ropivacaine 0.5% and Lidocaine 0.5% anestethic combination in performing locoregional anesthesia, using either peripheral nerve stimulator or ultrasounds for brachial plexus block.

Study design: A prospective randomized clinical study was performed at the County Emergency Clinical Hospital of Tîrgu Mureș, between January and May 2013 on patients undergoing elective or emergency surgical interventions on upper limbs with locoregional anesthesia. Brachial plexus block with axillary approach was performed in 65 patients using randomly the nerve stimulator or the ultrasound guided technique. The parameters recorded were the duration of the anesthetic technique, the installation time and the length of anesthesia. All anesthetic incidents during and after anesthesia were observed as well. The recorded data were analyzed and statistically processed.

Results: We enrolled 40 (61.5%) patients for the nerve stimulation technique and 25 (38.5%) patients for ultrasound guidance. The quality of the block was acceptable, an inadequate anesthesia was reported in 9 patients (13.8%). The mean time of installation of anesthesia was 34.36 (± 11.56) minutes, time recorded from the initiation of the anesthetic technique until complete motor block. The mean duration of the motor block was 481.3 (± 128.6) minutes which represents over 8 hours. None of the patients required conversion of the anesthesia due to the extended period of the surgical intervention. One patient presented a mild allergic reaction to the anesthetic drugs.

Conclusion: Combination of the ropivacaine and lidocaine can be safely used for locoregional anesthesia, especially in those cases where long surgical intervention time is anticipated or in order to achieve a better postoperative analgesia

Objectives: The aim of the study was to evaluate the variables that define the facial profile of a sample of the population in the centre of Romania, and to compare male’s and female’s soft tissue profile. These values could be useful in elaborating the aesthetic objectives for treating the population in this area.

Material and methods: Fifty subjects were included in the study - patients and students of the University of Medicine and Pharmacy of Tîrgu Mureș (29 females and 21 males) between 18 to 28 years of age, having dental class I and a balanced profile. The photographs were taken in the natural head position (NHP). The anthropometric points were recorded and four of the angles that characterize a harmonious profile were traced and measured: the nasofrontal angle (G-N-Nd), the nasolabial angle (Cm-Sn-Ls), the mentolabial angle (Li-Sm-Pg), and the facial angle (G-Sn-Pg).

Results: The values obtained for the two sexes were compared using the t-student test. All angles had values that were larger for females (nasofrontal: females 137.1 degrees, males 135.79 degrees, p = 0.0019; nasolabial: females 105.3 degrees, males 102.19 degrees, p = 0.00002; mentolabial angle: females 126.07 degrees, males 118.27 degrees, p = 0.000009; facial angle: females 170.32 degrees, males 168.85 degrees, p = 0.0033).

Conclusions: Differences between the two sexes were obtained, all angles were statistically significant larger in females. These results show that for the population in the centre of Romania the treatment objectives are different for females and for males. The angular values range between those that characterize the Caucasian population.
ESTIMATING GAS AND ROCK OUTBURST RISK ON THE BASIS OF KNOWLEDGE AND EXPERIENCE – THE EXPERT SYSTEM BASED ON FUZZY LOGIC
Authors: Skoczylas Norbert
Published: May 2014

The Author endeavored to consult some of the Polish experts who deal with assessing and preventing outburst hazards as to their knowledge and experience. On the basis of this knowledge, an expert system, based on fuzzy logic, was created. The system allows automatic assessment of outburst hazard. The work was completed in two stages. The first stage involved researching relevant sources and rules concerning outburst hazard, and, subsequently, determining a number of parameters measured or observed in the mining industry that are potentially connected with the outburst phenomenon and can be useful when estimating outburst hazard. Then, the Author contacted selected experts who are actively involved in preventing outburst hazard, both in the industry and science field. The experts were anonymously surveyed, which made it possible to select the parameters which are the most essential in assessing outburst hazard. The second stage involved gaining knowledge from the experts by means of a questionnaire-interview. Subjective opinions on estimating outburst hazard on the basis of the parameters selected during the first stage were then systematized using the structures typical of the expert system based on fuzzy logic.
VALUE OF GEOLOGICAL INFORMATION IN EXPLOITATION MANAGEMENT: THE CASE OF EXPLOITATION UNITS OF THE POLKOWICE-SIEROSZOWICE MINE
Authors: Krzak Mariusz , Panajew Paweł
Published: May 2014

The application of mathematical techniques of management is particularly significant in managing mineral deposits as well as generally in the mining industry, in which the execution of geological-mining projects is usually time-consuming and expensive. Such projects are usually undertaken in conditions of uncertainty, and the incurred expenses do not always generate satisfactory revenues. Mineral deposit management requires close cooperation between the geologist providing necessary information about the deposit and the miner conducting exploitation work. A real decision-making problem was undertaken, in which three exploitation divisions of a certain area in the Polkowice-Sieroszowice mine, differing in ore quality, could be developed in an order which would guarantee maximisation of income. First, the ore price was calculated with the NSR formula; next, the decision-making problem was presented as a kind of game between the geologist (the mine) and states of Nature.

The aim of this study was to evaluate the effects of the administration of a species-specific probiotic (Lactobacillus animalis SB310, Lactobacillus paracasei subsp. paracasei SB137 and Bacillus coagulans SB117 in a 30:35:35 ratio, respectively; 1.8 × 1010 CFU/g of powder) on gut microbial balance, immune response and growth performance of Holstein female calves during the first month of life. Twenty-two calves were divided into two experimental groups from 2 to 28 days of life: control (C), fed with milk replacer and concentrate as a basal diet, and treatment (T), fed C diet plus 1 g/calf/day of probiotic powder for the first month of age. Faecal and blood samples were individually collected and analysed weekly. Individual faecal score was recorded daily and general health score was calculated at the end of the trial. Cell-mediated immune response was evaluated by skin test at 7 and 28 days of life. Milk replacer and concentrate intake were recorded daily, while body weight and biometrical parameters were recorded at 2, 8, 14, 21 and 28 days of life, thus average daily gain and feed conversion rate were calculated. During the first week of treatment, lower blood eosinophil percentage (0.05% vs. 0.22%; P≤0.01) was found in T group, while basophils were higher in T than C group at the end of the trial (0.21% vs. 0.16%; P≤0.05). Higher faecal lactic acid bacteria (LAB)/E. coli ratio on day 28 of life (3.73 log CFU/g vs. 2.02 log CFU/g; P≤0.05) and lower incidence of diarrhoea were found in the treated group (63.30% vs. 70.71%; P=0.05). Body weight (48.92 kg vs. 46.92 kg; P≤0.05), total concentrate intake (14.77 kg vs. 12.56 kg on dry matter basis; P≤0.05), and heart girth (81.16 cm vs. 78.49 cm; P≤0.05) were significantly higher in T group. The administration of the probiotic during the first month of life improved gut microbiota and increased the growth performance and some biometric parameters of calves.

Published: May 2014

The population of the European brown hare (Lepus europaeus) has been declining for the last decades in many European countries, including Poland. The goal of this study was to determine the level of endoparasite infection among hares. In 2007-2010, 83 animals were examined postmortem. The animals were weighed and analysed according to age and sex. During the dissection only the following nematodes were noticed: Trichostrongylus retortaeformis, Strongyloides papillosus, Trichuris leporis and Passalurus ambiguus in the intestinal tract and Protostrongylus pulmonalis in lungs. Body mass of hares was analysed with a general linear model (GLM) with age, sex, and presence/ absence of nematode infection as factors. The proportion of infected and uninfected hares with protozoan coccidia was compared with Fisher exact test for 2×2 contingency tables, whereas the proportion of nematode infection was compared by χ2 test. There was a significant difference in the proportion of hares infected and not infected by coccidia with the higher proportion of infected juvenile individuals (P=0.010), whereas there was no difference between males and females (P=0.41). The frequencies of hares infected vs. not infected by nematodes did not differ between sex (χ2=1.89, P=0.168) and age (χ2=0.0007, P=0.97). The mean body mass of all hares was 4.15 kg±0.40 kg. GLM model conducted for body mass of hares showed that there was a significant difference only between juvenile and adult hares (F=24.225, P=0.000005) and no significant association between the level of endoparasite infection and sex

The objective of this study was to investigate the effect of the range of pH decline from 45 min to 48 h after the slaughter on the quality of meat in (Landrace × Yorkshire) × Hampshire fattening pigs. The mean value and standard deviation for the range of pH fall from 45 min to 48 h postmortem served to create the following experimental groups: group I with pH decline less or equal to 0.88 units pH; group II with pH decline higher than 0.88 but lower than 1.26 pH units; and group III where pH decline was equal to 1.26 units or higher. This investigation showed that glycolytic resources in meat (glycogen and lactate) were connected with the range of pH decline from 45 min to 48 h postmortem. The different ultimate pH in meat with the same lactate concentration was noted (group I vs. II). Although the range and the rate of pH decline from 3 h postmortem was higher and significantly faster (P≤0.05 and 0.01) in both groups with a higher pH fall (groups II and III), there was no statistically confirmed influence of the investigated range of pH fall on drip loss and on colour. The average values for drip loss and colour obtained in this experiment were related to ultimate pH of meat of (L × Y) × H fatteners, being characteristic for acid meat

Implementation of airbags systems in motor vehicles designed to transport of persons led in time to a significant decrease of the rate of death among passengers involved in car accidents. However airbag systems are not harmless, it produces lesions that vary in intensity depending on many factors. But decidedly, we can meet injuries associated with the triggering of the airbag system. Therefore, it must be made a clear difference between the two types of injuries, this being particularly important in terms of medico-legal especially regarding the mechanism of injury.

Published: May 2014

Fractures of the horizontal surface of the distal tibia are known commonly as pylon or plafond fractures, and represent 1-5% of lower extremity fractures, 7-10% of all tibial fractures. The protocol consisted of immediate (within eight to 24 hours) open reduction and internal fixation of the fibula, using a fibular plate or one third tubular plate and application of an external fixator spanning the ankle joint. In the second stage, the treatment of proximal and distal tibial fractures with close reduction and MIPPO technique can preserve soft tissue, simplify operative procedure and decrease wound, obtain rigid internal fixation and guarantee early function exercises of ankle joint. In this study we evaluated 22 patients treated in Clinical Emergency Hospital Constanta between April 2012 - July 2013 diagnosed with multifragmentary fractures of the distal tibia. This study evaluates the treatment of complex fractures of distal tibia with locked plate after external fixation. There were 17 males and 5 females of mean age 51,7 years (31-68). The mean follow-up period was 14 weeks. (Ranging from 9-16 weeks). All patients were fully weight bearing at 16 weeks (ranging 9-16 weeks) showing radiological union. There were no cases of failures of fixation, or rotational misalignment. No significant complication was observed in our patients. MIPO is an effective method of treatment for distal tibial fractures, reduce surgical trauma and maintain a more biologically favorable environment for fracture healing, reducing risks of infection and nonunion.

The work deals with habitats of Romulea bulbocodium and Romulea linaresii ssp. graeca in the southern Balkans. Both species appear in early spring ephemeral therophytic non-nitrophilous grasslands in regions under the influence of the Mediterranean climate. These communities are classified within the Romulion alliance, which encompasses such communities from the eastern Mediterranean area. It was established that the main climatic factor causing the diversity of these communities is seasonality in precipitation and temperature. Two associations are presented, as Lagopo-Poetum bulbosae and Romuleo graecae-Poetum bulbosae.

The side effects of certain antibiotics have been a recent dilemma in the medical arena. Due this fact, the necessity of natural product discovery could provide important indications against several pharmacological targets and combat many infectious agents. Piper arboreum Aub. (Piperaceae) has been used by Brazilian traditional communities against several illnesses including rheumatism, bronchitis, sexually transmitted diseases and complaints of the urinary tract. Medicinal plants are a source of several remedies used in clinical practice to combat microbial infections. In this study, ethanol extract and fractions of Piper arboreum leaves were used to assay antimicrobial and modulatory activity. The minimum inhibitory concentration (MIC) was determined using microdilution method of ethanol extract and fractions from the leaves of P. arboreum ranging between 8 and 1024 μg mL-1. The capacity of these natural products to enhance the activity of antibiotic and antifungal drugs was also assayed. In these tests, natural products were combined with drugs. The natural products assayed did not demonstrate any clinically relevant antimicrobial activity (MIC ≥ 1024 μg mL-1). However, the modulation of antibiotic activity assay observed a synergistic activity of natural products combined with antifungal (such as nystatin and amphotericin B) and antibiotic drugs (such as amikacin, gentamicin and kanamycin). According to these results, these natural products can be an interesting alternative not only to combat infectious diseases caused by bacteria or fungi, but also to combat enhanced resistance of microorganisms to antibiotic and antifungal drugs.

Authors: Chariete A. , Bakhouya M. , Gaber J. , Wack M.
Published: May 2014

This paper provides an overview of a design space exploration methodology for customizing or tuning a candidate OCI architecture, given a resources budget and independent of a particular application traffic pattern. Three main approaches are introduced. The first approach allows customizing the On- Chip Interconnect by adding strategic long-rang links, while the second consists in customizing the buffer sizes at each switch according to the traffic. The third approach uses a feedback control-based mechanism for dynamic congestion avoidance. Some results are presented to shed more light on the usefulness of these approaches for System-on-Chip design.
Discrete-time modeling and input-output linearization of current-fed induction motors for torque and stator flux decoupled control
Authors: Enev Stanislav
Published: May 2014

In this paper an exact discrete-time model of the induction motor in a current-fed mode, including stator flux components is derived and validated. The equations of the motor are written in a frame aligned with the rotor electrical position, which results in a linear, time-invariant system. Based on the derived exact discrete-time representation of the motor dynamics, an input-output linearizing control law is designed for decoupled torque and stator flux control. The applied design technique led to a non-trivial, still useful, definition of the electromagnetic output of the motor. Simulation results are presented showing that the aimed performance is obtained, that is, no coupling exists between the outputs, and the initial design problem of controlling a nonlinear interacting TITO system is reduced to a problem of controlling two linear and decoupled SISO systems with simple dynamics.
Active Ageing –The EU’s Response To The Demographic Challenge
Authors: Wysokińska Zofia
Published: May 2014

Europe’s demographic problem (an ageing population) is well-known and has been the object of a number of research projects in the EU. As an example of the scale of the problem, the percentage of persons 55 or older in the overall population of the EU was 30% in 2010, and is expected to rise to 37% in 2030. Raising the retirement age – the response implemented in a number of EU Member States in recent years – cannot be considered as a comprehensive solution to the problem. Older persons encounter more difficulties finding employment, even though they possess knowledge and experience which could be valuable in the conduct of economic activities. Recent years have witnessed a growth in the trend toward “active ageing”, which is considered to be ‘a process of optimization of the chances for good health, active participation, and security, in order to improve the quality of life over the passage of time’, a concept closely correlated with the idea of entrepreneurship among the elderly.It can be noted that there is no comprehensive policy supporting entrepreneurship of elderly people in the age of the Ageing Society in Europe. The aim of the paper is to present the foreseen benefits of the development of enterpreneurship of elderly people supporting policy in the EU and in Poland.

Published: May 2014

There are two aims of this study. The first is to outline the developments in the maritime economy and employment in the South Baltic Region, and the second to identify the emerging activities in the maritime industry and to reveal the prospects and potential for labour market development, taking into account the demand for labour, required professions, qualifications of the labour force, and feasible cross-border mobility. This comparative study refers to four EU Baltic coast regions, namely the Mecklenburg-Vorpommern (D), Zachodniopomorskie (PL), Pomorskie (PL) and Klaipeda (LT) regions. Prospects for the economic development and employment potential specified for each region and selected segments of the maritime economy are consequently elaborated. The analysis of the maritime economy in the South Baltic Region reveals some crucial differences in terms of strategic maritime activities and employment potential and prospects for each of the regions. The phenomenon of the diverse demand for labour force through the various segments of the maritime economy and by region has been identified and is presented in the form of a comprehensive matrix of the projected demand for labour.

Published: May 2014

Mechanical damage of seeds due to harvest, handling and other process is an important factor that affects the quality and quaintly of seeds. Seed damage results in lower grain value, storability problem, and reduces seed germination and seedling vigor and subsequent yield of crops. The objectives were to determine the effect of different levels of zinc sulphate fertilization on the breakage susceptibility of three irrigated wheat varieties (Bahar, Shiraz and Pyshtaz). An experiment was conduct at the Experimental research station of Lorestan University, Iran. A factorial experiment was conducted with three replicates in a completely randomized block design (CRBD). Factors included three levels of zinc sulphate. Zinc sulphate treatments were combinations of three fertilization rates (0 - control, 25 and 50 kg/ha) at three replicates. The harvested seeds were subjected to impact energies of 0.05 and 0.1 J at constant moisture contents of 9.8, 15 and 20% using an impact test apparatus. The analysis of variance showed that wheat variety, fertilization level of zinc sulphate and moisture content significantly influenced breakage susceptibility of wheat seeds at the 1% probability level. Resistance to the breakage of wheat seeds for all varieties increased, as polynomial functions, with increase in the zinc sulphate rate. The average values of percentage breakage of seeds decreased from 37.07 to 27.80% as the fertilization level of zinc sulphate increased from 0 to 50 kg/ha. Bahar variety exhibited the highest resistance to breakage than other varieties. As the moisture content increased from 9.8 to 20% the percentage breakage of seeds decreased from 36.58 to 30.03%. Increasing the impact energy from 0.05 to 0.1 J caused an increase in the percentage breakage of seeds from 16.19 to 50.47%.

Authors: Keivanrad S. , Zandi P.
Published: May 2014

The study investigated agronomical and qualitative features of Indian mustard in a semi-arid region from Iran. Field trials were designed in split plot arrangement based on a Randomized Complete Block Design with three replicates at the Agricultural Faculty of Takestan, Iran. In the study, plant height (cm), the number of seeds in the siliqua (seed/siliqua), the number of siliquae in the plant (siliqua/plant), seed yield (kg/ha), biological yield (kg/ha), thousand-seed weight (g), harvest index (%), oil content (%) and oil yield (kg/ha) were determined. The all growth and yield parameters of mustard plant were significantly affected by nitrogen fertilization. All the parameters, except for harvest index (HI), were drastically affected by used densities. The highest seed yield and oil yield (2961 and 1159 kg/ha, respectively) were obtained for the crop utilized with 200 kg N/ha in plots with 80 plants/m2. The maximum oil content (43.97%) was recorded in the lowest plant density (80 plants/m2) and nitrogen application level of 50 kg/ha. Results suggest that in semi-arid region of Takestan, researchers must direct their selection treatments to increase oil quality of Indian mustard

Published: May 2014

The velocity field around the standard Rushton turbine was investigated by the Laser Doppler Anemometry (LDA) and Particle Image Velocimetry (PIV) measurements. The mean ensembleaveraged velocity profiles and root mean square values of fluctuations were evaluated at two different regions. The first one was in the discharge stream in the radial direction from the impeller where the radial flow is dominant and it is commonly modelled as a swirling turbulent jet. The validity range of the turbulent jet model was studied. The second evaluated region is under the impeller where flow seems to be at first sight rather rigorous but obtained results show nonnegligible values of fluctuation velocity.

Published: May 2014

Electron paramagnetic resonance investigations of paramagnetic centers in whole human blood were carried out at 170 K using X-band EPR spectrometer. The study included a group of patients and healthy volunteers. The EPR signals from high spin Fe3+ ions in transferrin (g = 4.2) and Cu2+ ions in ceruloplasmin (g = 2.05) are characteristic of each frozen blood sample. An overview of all recorded spectra revealed in several cases additional lines derived from high spin Fe3+ ions in methemoglobin (g = 5.8 - 6), free radicals (g = 2.002 - 2.005) and various low spin ferriheme complexes (g = 2.21 - 2.91). The lines from cytochromes (g = 3.03 and 3.27) were observed only twice. The EPR measurements have not confirmed the correlation between the occurrence of a particular type of low-spin iron complex and a specific disease entity. Moreover, the presence of EPR lines from trivalent iron also did not differentiate patients from healthy volunteers.

Authors: Peško Matúš , Kráľová Katarína
Published: May 2014

Adverse effect of nickel on hydroponically cultivated plants of two Brasssica napus L. cultivars (Verona and Viking) was investigated. Dry mass of shoots and roots as well as some biochemical characteristics (concentration of photosynthetic pigments, TBARS and proteins) of plant leaves were determined. In addition, the content of nickel in plant organs was estimated. Visible symptoms of Ni toxicity were notable already at the lowest applied concentration (6 μmol · dm-3). Higher applied Ni concentrations (24, 60 and 120 μmol · dm-3) resulted in moderate to strong toxic effects on plants of both studied cultivars. After application of 6 and 12 μmol · dm-3 Ni shoot dry mass of cv. Viking was substantial lower than that of cv. Verona. Decrease of root dry mass after treatment with 6, 12 and 120 μmol · dm-3 Ni was similar for both cultivars. Strong decrease in content of photosynthetic pigments was observed after application of 120 μmol · dm-3. Comparing to the control, the content of these pigments in leaves of plants dropped under 50% (both cultivars). The highest applied Ni concentration 120 μmol · dm-3 caused that protein content in leaves dropped by 39% (cv. Verona) and 37% (cv. Viking) comparing to the control plants. After application of 120 μmol · dm-3 Ni the content of malondialdehyde in leaves was 2.64- (Viking) and 2.31- (Verona) times higher than that of control. Nickel amounts accumulated in roots of plants were higher than those in shoots. Accumulated Ni amounts in roots of cv. Verona plants were 1.3- (120 μmol · dm-3) to 1.9- (6 μmol · dm-3) times lower than those of cv. Viking plants, whereas metal amounts accumulated in shoots of cv. Verona plants were 1.2- (120 μmol · dm-3) to 1.8- (6 μmol · dm-3) times lower than those of cv. Viking plants.
