Article history Received 22.08. 2017 Accepted 09.10. 2017 Available online 30.10. 2017 Abstract Results of research connected with determining the degree of implementation of 5S practices in ceramics industry are discussed in this paper. Direct survey with employees of companies plus expert interview was used in the research. A 21 point scale was used to assess the degree of implementation the 5S practices at individual stages of the manufacturing process. The specificity of production in ceramics industry enforces maintaining the regime of cleanliness during production. The research revealed that the level of conscious implementation of the 5S practices in companies depends on the culture of organization and the degree of involvement of employees in the improvement actions in their company. The presented results are a part of the research aimed at determining reference requirements for companies in terms of implementation and making use of the Lean Management (LM) instruments.
Antibacterial Activity of Sophorolipids Produced by Candida bombicola on Gram-positive and Gram-negative Bacteria Isolated from Salted Hides

Salted hides and soaked hides treated with certain antibacterial agents, may still contain different proteolytic and lipolytic Gram-positive and Gram-negative bacteria that affect the quality of leather adversely. The prevalence of bacteria resistant to antimicrobial agents in the leather industry has drawn attention of scientists to search new and effective antimicrobial agents. Examination of antimicrobial glycolipids such as sophorolipids for their effectiveness against proteolytic and lipolytic hidedegrading microorganisms, may offer important information. Hence, we describe a research that evaluates the susceptibility of various hide-degrading bacteria to sophorolipids. These extracellular glycolipids were produced by fermentation using Candida bombicola ATCC 22214. Palmitic acid, stearic acid, and oleic acid were used respectively to produce SL-p, SL-s, and SL-o. The minimal inhibitory concentrations (MICs) of SL-p, SL-s, and SL-o against Gram-positive endospore-forming bacteria (Bacillus licheniformis, B. pumilus and B. mycoides), Gram-positive bacteria (Enterococcus faecium, Aerococcus viridans, Staphylococcus xylosus, S. cohnii and S. equorum), Gram-negative bacteria (Pseudomonas luteola, Enterobacter cloacae, E. sakazakii and Vibrio fluvialis), and mixed culture of these isolates were examined using an agar dilution method. The MICs of both SL-p and SL-o against the test bacteria were determined as 19.5 μg/mL, with an exception that E. cloacae was inhibited by SL-o at a MIC of 9.76 μg/mL. Although MICs of SL-p did not change against the test bacteria, the MICs of SL-s (ranging from 4.88 μg/mL to 19.5 μg/ mL) changed according to species of the test bacteria. The lowest MICs of SL-s were found to be 4.88 μg/mL against B. licheniformis, B. pumilus, P. luteola, S. xylosus and B. mycoides. The MICs of SL-p, SL-s, and SL-o against the mixed bacterial culture were detected as the same (19.5 μg/mL). In conclusion, SL-p, SL-s, and SL-o inhibited the growth of 12 different hide bacteria and their mixed culture, and have broad-spectrum activity. The results obtained in the present study may be valuable for the development of SL-p, SL-s, and SL-o as antimicrobial surfactants in the preservation and soaking processes of hides and skins.
USING OF SOME ENVIRONMENTALLY SAFE TREATMENTS TO IMPROVE THE STORABILITY OF NAVEL ORANGE (CITRUS SINENSIS L.) FRUITS

This investigation was carried out during two successive seasons 2013 and 2014 on fruits of Washington Navel orange (Citrus sinensis L.). The experiment was conducted to evaluate the influence of some environmentally safe matural products to improve the storability of Navel orange (citrus sinensis) fruits during 2013 and 2014 seasons, Jojoba oil (1,3,5)%, castor oil (0.5, 1,2)%, yeast (1,2,3)%, seaweed (1,2,3)%, hot water (45ᵒC and commercial wax were used for proposed study, After the application of the treatments on the fruits, fruits were stored at a temperature of 5°±1 C and 90%±5 of relative humidity for 60 days, physical characteristics (weight loss%, decay% and the peel's thickness of the crust) and chemical properties (total phenols) were determined. Results indicated that, castor oil (2 and 1)% and jojoba oil 5% reduced the deterioration in weight loss%, decay%, peel thickness, and phenols content, compared to the content was obtained in control. So the results show that, coating orange fruits with castor oil (1, 2)% and jojoba oil (5)% had the most effective in improve the storability of orange fruits Navel Orange (Citrus sinensis L.).
A revision of Australian Plagiochila (Lophocoleinae: Jungermanniopsida)

Fifty-five Plagiochila species are recognized for Australia and New Zealand. Nine of these are new, all from Australia eight of which come from the Wet Tropics Bioregion of north east Queensland and one from the south-eastern mesic archipelago. Four of the new species belong in the challenging, and neglected, section Vagae. Three species are new Australian records, P. daviesiana, P. monospiris, and P. streimannii; and one species, P. alta, is a new record for New Zealand. Six species, P. annotina, P. circumdentata, P. colensoi, P. deltoidea, P. gigantea and P. ramosissima, are excluded from Australia as these are all New Zealand endemics reported in error for Australia. One New Zealand species is reported new for Australia (P. baylisii). Four species are excluded from Australia, P. furcata, P. inflata, P. renitens and P. sciophila, as they are based on misidentifications or are not supported by voucher material or both. Another interpretation of the confusion surrounding the name Plagiochila baileyana is presented, wherein Plagiochila baileyana is accepted as a species distinct from P. gigantea, while Plagiochila aculeata is returned to synonymy of P. fasciculata, and Plagiochila subfasciculata Colenso is reinstated. The number of Plagiochila species in Australia increases from 32 to 41, but the number of species in New Zealand decreases from 28 to 27 as a result of this study. New combinations at species level are also proposed for a variety of P. blepharophora from Fiji and two varieties of P. gymnoclada from Sumatra and Java, two species which morphological data suggests are grossly polyphyletic as currently circumscribed.
Metabolism-Induced Oxidative Stress and DNA Damage Selectively Trigger Genome Instability in Polyploid Cells

Understanding the forces impacting genome stability is important for diverse processes such as tumorigenesis and reproductive biology. The pathogenic yeast Candida albicans displays unusual genome dynamics in which tetraploid cells, but not diploid cells, become unstable when grown on a glucose-rich ‘pre-sporulation’ medium. Here, we reveal that C. albicans polyploid cells are metabolically hyperactive on this medium as evidenced by increased expression of metabolic genes as well as higher rates of fermentation and oxidative respiration. These cells also show elevated levels of reactive oxygen species (ROS), activate the ROS-responsive transcription factor Cap1, and accrue DNA double-strand breaks. Suppression of ROS levels reduced oxidative stress, DNA damage and chromosome instability. These studies reveal how metabolic flux can generate endogenous ROS, triggering DNA damage and genome instability in polyploid, but not diploid, cells. We discuss parallels with metabolism-induced instability in cancer cells and propose that ROS-induced DNA damage could have facilitated ploidy cycling in eukaryotes prior to the evolution of meiosis.
Биогеохимическая оценка состояния почвенно-растительного покрова в промышленных, селитебных и рекреационных зонах Санкт-Петербурга

Soils and plants of Saint Petersburg are under the constant technogenic stress caused by human activity in industrial, residential, and recreational landscapes of the city. To assess the transformed landscapes of various functional zones, we studied utility, housing, and park districts with a total area of over 7,000 hectares in the southern part of the city during the summer seasons of 2016-2018. Throughout the fieldwork period, 796 individual pairs of soil and plant samples were collected. A complex of consequent laboratory studies performed in an accredited laboratory allowed the characterization of key biogeochemical patterns of urban regolith specimens and herbage samples of various grasses. Chemical analyses provided information on the concentrations of polluting metals in soils and plants of different land use zones. Data interpretation and calculation of element accumulation factors revealed areas with the most unfavorable environmental conditions. We believe that a high pollution level in southern city districts has led to a significant degree of physical, chemical, and biological degradation of the soil and vegetation cover. As of today, approximately 10 % of the Technosols in the study area have completely lost the ability to biological self-revitalization, which results in ecosystem malfunction and the urgent need for land remediation.
Analysing and Combining Static Pruning Techniques for Classical Planning Tasks

In classical AI planning, the state explosion problem is a reoccurring subject: although the problem descriptions are compact, often a huge number of states needs to be considered. One way to tackle this problem is to use static pruning methods which reduce the number of variables and operators in the problem description before the planning. In this work, we discuss the properties and limitations of three existing static pruning techniques with a focus on satisficing planning. We analyse these pruning techniques and their combinations, and identify synergy effects between them and the domains and problem structures in which they occur. We implement the three methods into an existing propositional planner, and evaluate the performance of different configurations and combinations in a set of experiments on IPC benchmarks. We observe that static pruning techniques can increase the number of solved problems, and that the synergy effects of the combinations also occur on IPC benchmarks, although they do not lead to a major performance increase.
Spatial ecology and multi-scale habitat selection by Western Painted Turtles (Chrysemys picta bellii) in an urban area

As urban centres expand, knowledge on the habitat and space use of native wildlife, particularly long-lived species, is required for proper management. Our objective was to understand space requirements and key habitat features necessary for long-term persistence of Western Painted Turtles (Chrysemys picta bellii) living in a Canadian urban park. Using radio telemetry, we examined seasonal habitat selection and space use over two years, 2015–2016 (n = 23), and 2016–2017 (n = 29) in Regina, Saskatchewan. Daily movements and home ranges of males and females were smaller during emergence than during nesting or post-nesting phases of the active season. Turtles inhabiting marsh sites had 2- and 4-times larger daily movements and home ranges compared to turtles inhabiting the creek. Turtles selected the shoreline habitat over urban/parkland and open water. Turtles used marsh-shoreline habitats non-randomly, selecting accessible shoreline with large trees in the active season. In contrast, turtles used creek-shoreline habitat according to availability. Overwintering sites selected by turtles were warmer and deeper than random available sites, with no difference in dissolved oxygen level. However, water was hypoxic for most overwintering sites. Our results show that turtles range widely, requiring 20–60 ha throughout the year. Urban park areas should be managed to provide accessible shorelines with a combination of cover and open basking areas. Critically, careful attention needs to be paid to managing water depth so that over-wintering sites remain viable.
Estimation of Membrane Curvature for Cryo-Electron Tomography

Curvature is an important morphological descriptor of cellular membranes. Cryo-electron tomography (cryo-ET) is particularly well-suited to visualize and analyze membrane morphology in a close-to-native state and high resolution. However, current curvature estimation methods cannot be applied directly to membrane segmentations in cryo-ET. Additionally, a reliable estimation requires to cope with quantization noise. Here, we developed and implemented a method for membrane curvature estimation from tomogram segmentations. From a membrane segmentation, a signed surface (triangle mesh) is first extracted. The triangle mesh is then represented by a graph (vertices and edges), which facilitates finding neighboring triangles and the calculation of geodesic distances necessary for local curvature estimation. Here, we present several approaches for accurate curvature estimation based on tensor voting. Beside curvatures, these methods also provide robust estimations of surface normals and principal directions. We tested the different methods on benchmark surfaces with known curvature, demonstrating the validity of these methods and their robustness to quantization noise. We also applied two of these approaches to biological cryo-ET data. The results allowed us to determine the best approach to estimate membrane curvature in cellular cryo-ET data.
Julian Grond Optimal quantum control of trapped Bose-Einstein condensates

Magnetic microtraps on atom chips enable precise and robust quantum control of BoseEinstein condensates (BECs). These are macroscopic quantum objects which are very well isolated from the environment. A key application is an atom interferometer built with trapped BECs. The major goal of this thesis is the optimal quantum control of trapped BECs for atom interferometry applications, as well as a better understanding of the involved physical processes. For control purposes and for non-adiabatic condensate dynamics, elaborate time dependent methods are necessary. We use the Multi-configurational time-dependent Hartree for Bosons (MCTDHB) method, which provides a hierarchy of efficient approximation schemes. Realization of atom interferometers will require elaborate control strategies. We implement thus Optimal control theory for MCTDHB and apply it to several problems. One application is number squeezing by splitting of BECs, which we achieve one order of magnitude faster as compared to quasi-adiabatic splitting. The rapid condensate dynamics resulting from our OCT protocols poses the general question about condensate excitations and stability of the condensate during splitting. Simulations with more than two modes allow us to obtain insight into the many-body dynamics. We analyse trapped BEC interferometers in presence of interactions, in particular the optimal input states and how they can be prepared using quantum control. We find that the MZ interferometer is particularly promising, if Bayesian phase estimation is used. We conclude that phase diffusion is not a substantial limitation for atom interferometry, which could have significant impact on the realization of atom interferometers.
MSc Particles, Strings & Cosmology: Dissertation Higher-Spin Gauge Theories, Vasiliev Theory and Holography

Higher-spin gauge theories are a rich and fascinating topic and in particular the question of interactions represents a severe technical challenge in light of the many deep no-go results. We present an introduction to free higher-spin gauge theories in 4d flat space, beginning with a discussion of the most well-known and pertinent of the no-go theorems concerning higher-spin interactions and the means to evade them in a physically interesting setting. The representation theory of massless particles and higher-spin representations of the Lorentz group is discussed before the formalism of free higher-spin gauge boson field theory is presented and verified. The formalism of Vasiliev gauge theory is introduced and many of the salient features of the theory are reviewed, in particular the inherent description of higher-spin gauge fields and a massive scalar field propagating in AdS4 is discussed. The formalism of the AdS/CFT correspondence is presented and the method to determine, up to normalisation factors, holographic correlation functions is explained. Finally we describe how these holographic methods can be used to compute a tree-level higher-spin three-point function in Vasiliev theory.

Describing Scale Shape Morphology of Glossogobius Giuris using Landmark-based Geometric Morphometrics

In the conservation of biodiversity, natural resources, and fisheries management, species identification and population discrimination are necessary. In freshwater fishes, the scale morphology and squamation is important because this can be helpful in the identification of fishes up to the extensive levels of species, sex determination and pathology of fish. Glossogobius giuris is an endemic species and considered important in Balo-i, Lanao del Norte and Mandulog River in Iligan City, Philippines. It is locally known as “ kadurog ”. The fish is highly commercialized because it provides food for the community, thus this study was conducted. We used scale morphology to distinguish male and female of G. giuris using landmark-based geometric morphometrics. Results of the study have shown that there is no sexual dimorphism in the fish based on scale shapes. However, variations of the scales do exist within sexes based on the results of the relative warp analysis. The variations observed can be attributed to environmental factors affecting the development of the fish and thus resulting to phenotypic plasticity in the patterns of variation in the scale shapes among individuals.
