Evaluation of Fertigation Applied to Furrow and Overhead Irrigated Cotton Grown in a Black Vertosol in Southern Queensland, Australia
Authors: Antille Diogenes L. 
Published: February 2018

Abstract.Field trials were conducted at gated pipe surface and overhead irrigation sites established to cotton ( L.) to evaluate irrigation and fertigation management using a model-based control system. The control strategies determined the timing and volume of irrigation, and the rate of fertilizer-N to apply through fertigation. For this, nitrogen (N) was applied in-crop season using urea ammonium nitrate (UAN, 30% N solution) at a rate of 40 kg ha-1 N. At the furrows site, the uniformity of distribution of fertilizer-N applied through fertigation was satisfactory, which was achieved both at distance (600 m) and depth (0-600 mm). Applying fertilizer-N through fertigation, at the rate used in this study, showed relatively small (=8%) improvements in cotton yield, which was explained by relatively high N rates (180 kg ha-1 N) applied before planting. Given current price ratios (fertilizer-to-cotton), application of N through fertigation appears to be economical in both systems, but relative agronomic efficiencies and economic return from the fertilizer applied were lower in furrow compared with overhead (P&lt;0.05). Fertigation may be recommended when pre-season N application rates are low (e.g., &lt;100 kg ha-1 N), particularly in overhead irrigation as significantly higher efficiencies both in terms of water and N use can be achieved with this system. This would enable some of the operational constraints associated with application of N in-crop season to be overcome; thereby, reducing the need for high rates of N applied up-front. For the overhead system, there were also advantages compared with the furrow system in terms of reduced potential for N2O emissions after irrigation or fertigation. Overall, short-term (30-day period) soil emissions of N2O were approximately eight times higher in furrow compared with overhead. Emissions from non-fertigated crops were approximately two times higher in furrow compared with overhead. Emissions from the fertigated crop under the overhead system were comparable to the non-fertigated crop of the furrow system (P&gt;0.05). In both systems, fluxes were highest within five days of irrigation or fertigation, but they decreased significantly after that time as soil moisture content (water-filled pore space) and soil nitrate levels decreased due to crop uptake. Nitrous oxide fluxes were similar in furrow and overhead 15 days after the irrigation or fertigation event. Areas that warrant further investigation are presented and discussed, including the need for improved timing of fertilizer delivery during the irrigation cycle to ensure that N losses through leaching or gaseous evolution (e.g., N2O, N2) are not economically or environmentally significant.

Dental plaque prevention can be achieved by inhibition of mouth cavity microbes to built biofilm. Kaempferia galanga rhizome has been known as a potential antibacterial agent. This research aimed to reveal the potency of Kaempferia galanga extract and essential oil as anti plaque active agents, based on their in vitro inhibitory activity against the planktonic growth and biofilm of Streptococcus mutans ATCC 21752. Kaempferia galanga extract was obtained by defatting dried-pulverized samples in petroleum ether prior to immersion in 70% ethanol. The fresh rhizome was steam-hydro distilled for 6 h to yield the essential oil. Antibacterial and anti biofilm assays were measured by micro dilution technique on polystyrene 96-wells micro titer plates at 37°C. The percentage of inhibition was calculated by comparing the absorbance of samples to the vehicle (control) measured by micro plate reader at 595 nm. Biofilms formed were first stained by 1% crystal violet. The above assays were performed in triplicates. This study revealed that both K. galanga rhizome essential oil and ethanolic extract showed antibacterial and antibiofilm activity towards S. mutans. The ethanol extract showed MIC90 value at 0.091% w/v and MBC at 2.724% w/v for antibacterial activity; IC50 at 0.048 % w/v for anti biofilm formation activity; and EC50 at 0.052%w/v for biofilm degradation activity. Until the highest concentration tested (0.6%w/v), the MIC90 and MBC values of the essential oil were not revealed, but higher biofilm inhibitory activity i.e. IC50 at 0.025 % w/v; and EC50 at 0.034 %w/v were observed.

Authors: Yuan Qing , Xu Guang , Liang Weicheng , Zhou Mingxing , Hu Haijiang 
Published: February 2018

Abstract
The relationship between the passivation period of Si-containing steel and oxygen concentrations was investigated by conducting the oxidizing experiments employing four different oxygen concentrations on a simultaneous thermal analyzer (STA) at a heating temperature of 1260°C. The results show that the duration of passivation period increased with the increasing oxygen concentration. Moreover, the passivation period occurred at the oxygen concentrations ranging from 2.0 vol.% to 3.0 vol.%, whereas no visible passivation period was observed at the oxygen concentrations ≤1.5 vol.%. In addition, the oxidation mass gain versus time followed a linear relationship before the passivation period, which lasted for about 20 min when the mixed binary atmosphere was introduced into the sample chamber right from the beginning of the heating process.
Effect of 60 and 90 days of isotretinoin treatment on the structure of the small intestine mucosa in young male Wistar rats

Published: February 2018

Abstract
Isotretinoin is a substance used in cases of severe acne and acne resistant to other treatments. This skin disease affects patients of all ages and can interfere with social life, especially in adolescents. The drug acts by suppressing sebaceous gland activity and creating an inhospitable environment for Propionibacterium acne. The integrity of the small intestine is important for correct nutrition and patient treatment. We intended to assess the small intestine structure after treatment with 5 mg/kg isotretinoin solution and after a period without the drug, which could be considered a rest period. Young male Wistar rats (n=24) were separated into 4 groups (n=6): C: water; D0: soybean oil; D5a: 5 mg/kg; D5b: 5 mg/kg for 60 days followed by 30 days of rest period. Soybean oil was used to dilute the drug and it was offered daily by gavage. The animals were euthanized and the duodenum, jejunum and ileum were collected for analysis with light and scanning electron microscopy. The treatment stimulated tissue proliferation in the jejunum and ileum but had no significant effect in the duodenum. The results also showed a modification in goblet cell frequency in the duodenum and ileum. A further finding was that some modifications disappeared during the rest period. The protocol showed that the small intestine was somewhat altered by the treatment yet no lasting damage was caused.

Published: February 2018

Abstract
In this study we investigated the effect of five therapeutically used drugs and four natural polyphenolic compounds on the mechanism of oxidative burst of human neutrophils concerning their participation in the generation of reactive oxygen species (ROS). The compounds investigated decreased the oxidative burst of whole blood in the rank order of potency: N-feruloylserotonin > quercetin > curcumin > arbutin > dithiaden > carvedilol. The generation of intracellular reactive oxygen species in isolated neutrophils decreased in the same rank order, while carvedilol was ineffective. Scavenging of extracellular oxygen radicals followed the rank order of potency: N-feruloylserotonin > curcumin > quercetin > dithiaden. Arbutin and carvedilol had no effect. All compounds tested increased the activity of caspase-3 in cell-free system indicating a positive effect on apoptosis of neutrophils. Activation of protein kinase C was significantly decreased by dithiaden, curcumin, quercetin and N-feruloylserotonin. Carvedilol, dithiaden, quercetin and arbutin reduced activated neutrophil myeloperoxidase release more significantly compared with their less pronounced effect on superoxide generation The presented results are indicative of pharmacological intervention with neutrophils in pathological processes. Of particular interest was the effect of natural compounds. Intracellular inhibition of oxidative burst in isolated neutrophils by the drugs tested and natural antioxidants has to be further analysed since ROS play an important role in immunological responses of neutrophils.

Published: February 2018

AbstractThe paper analyzes diachronically the evolution and complexity of tourist activity in Acapulco, which was a very significant part of the history of Mexico in the 20th century and even centuries before, it was configured as Mexican icon of tourism for the world. This study is supported by evolution and complexity theories. The research presented is qualitative, inductive, diachronic and hermeneutical; relies on heuristics, criticism and synthesis. Applied materials were documentary, bibliographic and historical sources and statistical records on tourist activity. It is concluded that Acapulco, throughout the evolution history, has been an important factor in the economic, social and historical development, related to tourism, arising as an enclave of freedom, fantasy, imagination and hedonism, located on a life cycle of replenishment or rejuvenation in a sub-stage of stagnation although that is not what strategists, society and private initiative want, due changes in market behavior, complex actions are demarcated, they are not sustainable but still are being applied.
Empirical Study on Intercultural Collaboration in Project Teams: Preliminary Research Findings
Authors: Badzińska Ewa 
Published: February 2018

AbstractThe cross-cultural differences and the intercultural aspects of the collaboration have become increasingly prevalent over recent years. Undoubtedly, this diversity may generate different patterns of behavior in project teams. The research goal of the exploratory study is to identify advantages and obstacles to collaboration in multicultural teams at designing business solutions among Polish students – participants in intensive entrepreneurship programme (IP) within the framework of the international ECMT+ project1. In addition, the cognitive goal is to diagnose entrepreneurial attitudes and determinants of setting up one’s own company. During the two-week workshops in multicultural project teams in March 2017 at Karelia University in Finland, a participant observation method was applied. The main research method was, however, a semi-structured direct interview based on a questionnaire. Respondents were chosen purposeful and included six Polish students from Poznan University of Technology who carried out business projects in six multicultural teams – in total 48 participants were from 14 countries worldwide. The obtained results of the study point to measurable benefits of intercultural collaboration in project teams. Great commitment of the teams to achieve the goal and their healthy competition all remain noteworthy. Undoubtedly, however, a great diversity of attitudes and views in multicultural teams, national experiences and entrepreneurial knowledge make it necessary to overcome additional barriers, especially those with cultural backgrounds. The main limitation to the study is the non-representativeness of the sample and being limited to Polish participants. The findings presented in the article are very preliminary and further investigation in this field is necessary, i.e. comparative studies covering the remaining workshop participants.

Published: February 2018

Abstract
The aim of the article is to present wellness programs as means leading to the creation of culture of health in organizations. The notion of culture of health is becoming increasingly important for companies as statistics show that the number of health-related work problems is steadily increasing. As a result, labor costs are systematically increasing. To tackle this problem, companies began to introduce health and wellness programs to improve the psychophysical health of their employees. The article includes an overview of the concept of health-promoting company culture. It also identifies factors determining its success among employees, defines factors that limit employee participation and presents good practices for disease prevention through employee-oriented programs. This article is based on a literature review, including both: literature and statistical data available in official data bases. In many cases, research confirms the usefulness of wellness programs in the process of building a corporate culture of health. It also shows factors limiting the usability of such programs, which leads to companies being able to develop and improve.
The status and population changes of the Little Owl(Athene noctua)in the south of Békés county (Hungary)

Published: February 2018

AbstractBetween 1995 and 2017 we carried out surveys on the Little Owl(Athene noctua)in Battonya town and Kevermes village in southern Békés county. In 2007 and 2017 we have surveyed nesting sites in the village and the outer areas of Kevermes. The population of the species was estimated at the beginning of the breeding season and in early summer with field observations. Between 1995 and 2017 we collected road-kill data within the entire administrative area of Battonya. We registered each fiund road-killed Little Owl. We found 64 road-kills in Battonya. The number of casualties of the species has increased unambiguously over the studied 23 years. Most of the road-killed Little Owls (53 individuals, 82.81% of the total) were found in summer (June–August). 51 road-killed individuals (79.69%) were noted in the outer areas of Battonya, and 13 specimens (20.31%) in the town. Our results highlight that vehicle traffic is an important mortality factor for the population. The Little Owl has a large population in this landscape, and the population size has increased over the last decade. In the background of this increase is most likely the rise in the number of abandoned houses because of the unfavourable economic and social situation in the region. The local pairs nested only on attics and roof structures in Kevermes, often in residential buildings. The buildings of modern agriculture do not meet the needs of the species. A large part of the population breeds in the village, because with the disappearance of the farms the breeding pairs of the outer areas of Kevermes have disappeared. However, in Battonya the species regularly breeds in the outer areas of the town. Finally, we also collected some ethnoecological data on how local people relate to the species.

Published: February 2018

AbstractThe prey composition of the Barn Owl(Tyto alba)can be monitored indirectly by pellet analysis and we used this method to investigate less known small mammal species of Zala County. The number and abundance of small mammal species depend on the structure of the landscape of Barn Owls’ hunting area, therefore we analysed landscape features in the surrounding circles with 2 km radius around the sampling sites. In 2016 we collected 1106 pellets from 13 sampling localities. From the pellets we identified 21 species of 3022 individuals of small mammals (more than 98% of prey). Among the 21 species there was the rare Parti-colured Bat(Vespertilio murinus)and a new species for the county the Steppe Mouse(Mus spicilegus). Positive correlation was found between the diversity of the small mammal fauna of each sampling site and the landscape complexity (number of the landscape patches) of the Barn Owl hunting area. Relative abundance of the Wood Mouse(Apodemus sylvaticus)showed positive correlation with the number of landscape patches, while the abundance of the Lesser White-toothed Shrew(Crocidura suaveolens), the Miller’s Water Shrew(Neomys anomalus), the Striped Field Mouse(Apodemus agrarius)and the Harvest Mouse(Micromys minutus)was higher in hunting areas with more homogenous landscapes. Significant correlations were found between the relative abundance of some small mammal species and the landscape structure of the potential hunting area of owls that confirmed the consistency in habitat preference of some species. Our results proved that the prey-composition of Barn Owls reflects the land use through the distribution and abundance of small mammal species, therefore this method is suitable for ecological analyses of landscape.
