Liquid-crystal-droplet optical microcavities Matja ž

The use of liquid-crystal droplets as optical microcavities and lasers is reviewed and possible applications are discussed. Liquid-crystal droplets are prepared by simple methods that enable scalable production since their internal structure is formed by self-assembly. Light is trapped in droplets due to total internal reflection on the surface due to refractive index mismatch or because of a photonic bandgap structure in cholesteric liquid crystals (CLCs). Light confinement gives rise to a variety of optical modes and by employing a fluorescent dye end external optical pumping, lasing can be achieved. Liquid-crystal-droplet cavities are largely tunable by applying an electric field or a temperature change. Such cavities can be used as temperature and chemical sensors, and tunable light sources and filters in future integrated soft photonic circuits. ARTICLE HISTORY Received 1 May 2016
Effect of Fruit Orientation on the Quality of Litchi ( Litchi chinenesis Sonn ) under the Agro-Climatic Conditions of Dera Ismail Khan – Pakistan

Effect of fruit orientation on the quality of litchi (litchi chinensis. Sonn) was studied in five cultivars viz; Purbi, Bedana, Bombai, Serai and Gola. Fruit was picked from upper and lower half portions of the tree and was subjected to physio-chemical analysis. Significant difference was found for all the parameters studied. The fruit at lower half was heavy in weight, pericarp and flesh with high acidity. However, stone weight, pH value, Vitamin C content and non-reducing sugars were found more in fruits collected from upper half of the tree. Picking might be started from lower half of the plant to get superior quality fruits.
A Proposed Framework to the Professional Dimensions of Audit Quality in Egypt in light of Audit Quality Framework Issued by IAASB

Dina Sayed Fadaly A proposed Framework to the Professional Dimensions of Audit Quality in Egypt in Light of Audit Quality Framework issued by IAASB Given the importance of the professional implications of the general framework issued by the IAASB in 2013, a need for further analysis of the most important dimensions of the audit quality as suggested by the IAASB emerged. This research attempted to recognize the audit quality dimensions proposed by the general framework, in order to be able to identify the main determinants of audit quality proposed by the framework from three different perspectives the audit firm perspective, the client perspective, and the professional practicing environment perspective. Afterwards the research aimed to tailor a similar framework that suits the Egyptian environment by identifying the professional dimensions of audit quality in Egypt based on both the literature point of view and the general framework of 2013 suggestions. A descriptive type of research is conducted, relying on secondary data, and a qualitative analysis took place to end up with a suggested framework for the Egyptian context along with a direction to the most important research areas in the field of audit quality in Egypt now and in the future.
RELATIONSHIP BETWEEN TEACHERS ’ COMPETENCIES AND MOTIVATION AT HIGHER EDUCATION LEVEL IN PAKISTAN

The current descriptive study aimed to explore the relationship between teachers’ competencies and motivation at higher education level in Pakistan. All teachers in public universities in Pakistan were included in population of the study. A reasonable sample of 596 teachers was selected by random sampling method. Among them 50 % trained and 50 % were not trained. Further to measure more reliable relationship sample was categorized as male and female teachers, trained and non trained teachers. Two separate instruments namely Teachers, competencies measurement scale (TCMS) and Teacher’s motivation survey were used to find out competencies and motivational level of both groups. Pearson was applied to analyze the relationship between two variables. Results of the study indicated that there was a significant positive correlation between competencies and motivation of teachers in each category at higher education level. It shows that more competent teachers are more motivated too. Keyword: Competencies, teachers’ motivation, higher education level

Isolation and identification of Clostridium chauvoei from cattle in Mymensingh city of Bangladesh

Black quarter (BQ), caused by Clostridium chauvoei, is an economically important, highly infectious bacterial disease of cattle, goat and sheep. The present study was conducted to isolate and identify the causal agent of BQ from field cases. A total of 32 samples from necropsied areas of suspected cattle brought to the Veterinary Teaching Hospital, Bangladesh Agricultural University, Mymensingh were collected. The samples were subjected for bacteriological culture followed by identification through a series of conventional bacteriological techniques, staining properties and biochemical tests. The bacteria were cultured in anaerobic condition using candle jar. Morphological characters of bacteria were observed after Gram stain. The suspected samples were subjected for several passages in liver infusion broth to get pure culture. On neomycin blood agar, the bacteria showed hemolysis. Based on the cultural and staining characteristics and biochemical tests, 4 (12.5%) out of 32 samples were detected as Clostridium chauvoei. It is concluded that Cl. chauvoei has been successfully isolated and identified from BQ affected cattle.
The influence of intrinsic perceptual cues on navigation and route selection in virtual environments

The principle aims of this thesis were to investigate the influence of intrinsic navigational cues in virtual environments and video games. Modern video games offer complex environments that may reflect real world spaces or represent landscapes from fantasy and fiction. The coherent design of these spaces can promote natural navigational flow without the requirement for extraneous guidance such as maps and arrows. The methods that designers use to create natural flow are complex and stratified utilising principles rooted in urban architectural design and navigational cues that are intrinsic to real-world wayfinding scenarios. The studies presented in this thesis analysed not only these commonly used architectural cues but also the potential for the reinforcing of these cues by the addition of lighting, visual and auditory cues. The primary focus of this thesis was a systematic and quantitatively rooted analysis of the impact lighting has on navigation and the levels at which variance in lighting makes a quantifiable difference to navigational choices within a virtual environment. The findings of this thesis offer clear guidance as to the influence that lighting has within virtual environments and specifies that thresholds at which the inclusion of guidance lighting begins to affect navigational choices and the levels that players become conscious of these cues. The thesis also analyses the temporal thresholds for the detection of changes in contrast, hue and texture within an environment. The relationship of other intrinsic cues such as the potential reinforcement or cue competition effects of both audio and other visual cues, for instance motion are quantitatively analysed. These data were reflected in the form of a series of heuristic design principles that augment those that underpin architectural and environmental design considerations by for instance suggesting levels of saliency for lighting cues or reinforcing existing cues via supporting audio guidance.
Antimicrobial Screening of Different Extracts of Piper longum Linn

The antibacterial and antifungal activities of various solvent extracts of Piper longum were determined against a wide variety of pathogenic bacteria and fungi respectively. Crude extracts of Piper longum showed mild to moderate activities against most of the tested bacteria. On the other hand, the antifungal activities exhibited by all the crude extracts were not prominent. Petroleum ether extracts of Piper longum were found to be inactive against most of the tested organisms. Ethyl acetate extracts showed relatively better anti-microbial effect against most of the tested organisms. It has been expected that the present work on antimicrobial screening of the plant materials will lead to the scientists who continue work may have clinical success concerning the killer diseases.
Firms Characteristics and Environmental Disclosure: A Comparative Study of Hospitality Industry of Indonesia, Malaysia and Thailand

This paper aims to examine the environmental disclosure of hospitality companies in Indonesia, Malaysia, and Thailand, as well as the relationship between company characteristics and its environmental disclosure. Company characteristics are identified by the educational background of commissioner, the size of the audit committee, the proportion of independent audit committee, and company size. Company’s environmental disclosure is measured using the GRI3.1. This study uses secondary data from hospitality companies’ annual reports in 2012-2014, which is obtained through Indonesia Stock Exchange (IDX), Bursa Malaysia, and The Stock Exchange of Thailand (SET) website. The sample of this study are 57 companies; 18 hospitality companies in Indonesia,21 hospitality companies in Malaysia, and 18 hospitality companies in Thailand that generated using purposive sampling method. ANOVA test result shows that there are differences in term of environmental disclosure in Indonesia, Malaysia, and Thailand. Meanwhile, based on the multiple regression analysis results, the educational background of commissioner, and proportion of independent audit committee have a positive effect on environmental disclosure. The size of the audit committee and company size has no significant effect on environmental disclosure.
Clair-Detroit River system : Phosphorusmass balance and implications for Lake Erie load reduction , monitoring , and climate change

Communicated by Craig Stow To support the 2012 Great Lakes Water Quality Agreement on reducing Lake Erie's phosphorus inputs, we integrated US and Canadian data to update and extend total phosphorus (TP) loads into and out of the St. ClairDetroit River System for 1998–2016. Themost significant changeswere decreased loads from LakeHuron caused bymussel-induced oligotrophication of the lake, and decreased loads from upgraded Great LakesWater Authority sewage treatment facilities in Detroit. By comparing Lake St. Clair inputs and outputs, we demonstrated that on average the lake retains 20% of its TP inputs. We also identified for the first time that loads from resuspended Lake Huron sediment were likely not always detected in US and Canadian monitoring programs due to mismatches in sampling and resuspension event frequencies, substantially underestimating the load. This additional load increased over time due to climate-induced decreases in Lake Huron ice cover and increases inwinter storm frequencies. Given this more complete load inventory, we estimated that to reach a 40% reduction in the Detroit River TP load to Lake Erie, accounting for the missed load, point and non-point sources other than that coming from Lake Huron and the atmospherewould have to be reduced by at least 50%. We also discuss the implications of discontinuous monitoring efforts. © 2018 The Author(s). Published by Elsevier B.V. on behalf of International Association for Great Lakes Research.

DimmStore: Memory Power Optimization for Database Systems

Memory can consume a substantial amount of power in database servers, yet memory power has received considerably less attention than CPU power. Memory power consumption is also highly non-proportional. Thus, memory power becomes even more significant in the common case in which a database server is either not completely busy or not completely full. In this paper, we study the application of two memory power optimization techniques - rank-aware allocation and rate-based layout - to database systems. By concentrating memory load, rather than spreading it out evenly, these techniques create and exploit memory idleness to achieve power savings. We have implemented these techniques in a prototype database system called DimmStore. DimmStore is part of a memory power testbed which includes customized hardware with direct power measurement capabilities, allowing us to measure the techniques' effectiveness. We use the testbed to empirically characterize the power saving opportunities provided by these techniques, as well as their performance impact, under YCSB and TPC-C workloads. Under simple YCSB workloads, power savings ranged up to 50%, depending on load and space utilization, with little performance impact. Savings were smaller, but still significant, for TPC-C, which has more complex data locality characteristics.
Insecticidal activity of culture filtrates from liquid medium of Beauveria bassiana isolates from South Sumatra (Indonesia) wetland soil against larvae of Spodoptera litura

Abstract. Ayudya DR, Herlinda S, Suwandi S. 2019. Insecticidal activity of culture filtrates from liquid medium of Beauveria bassiana isolates from South Sumatra (Indonesia) wetland soil against larvae of Spodoptera litura. Biodiversitas 20: 2101-2109. The obstacle in utilizing entomopathogenic fungi to control pest insects in wetlands is the inability of their isolates to survive during the saprophytic phase due to the soil being very acidic. Therefore, the exploration of fungi being able to survive in the acidic soil was utilized in the acidic ecosystem. This study aimed to test the toxic activity of Beauveria bassiana culture filtrates from liquid medium at pH 2.5 and 6 against Spodoptera litura larvae. Total of ten isolates collected from South Sumatra, Indonesia was grown in liquid media at pH of 2.5 and 6 for six weeks. The result showed that the culture filtrate from liquid medium at pH 6 was more toxic against the larvae than that at pH 2.5. The mortality of the larvae at pH 6 reached 92%, while that at pH 2.5 it reached 13.33% only. The findings of present study revealed that the culture filtrate isolates of BPdR, BJgTs, BSwTd2, BSwTd3, BSwTd4, BKKPp2 from pH 2.5 media still caused high larvae mortality (6.67-13.33%). These seven isolates are superior due to their toxic nature at pH 2.5. Consequently, present study has increased the chances of success in utilizing these isolates for biological control in acidic ecosystems, such as peatlands, tidal lowlands, and freshwater swamps.
Evaluation of Artificial Cover Units as a Sampling Technique and Habitat Enhancement for Madtoms in Rivers

Instream habitat degradation and loss are major threats to freshwater fishes and critical conservation issues among nongame species due to a lack of research and knowledge concerning their habitat requirements. Instream physical cover is an important component of fish habitat, especially for benthic species that require cover for reproduction and shelter from predators. One such species is the Carolina Madtom Noturus furiosus, a small, imperiled, nongame catfish that is endemic to the Neuse and Tar River basins of North Carolina. To enhance understanding of instream cover dynamics, we constructed artificial cover units from terra cotta materials and deployed them in rivers to (1) evaluate whether they could be an effective passive-sampling technique to estimate detection and occupancy of the Carolina Madtom and (2) determine their potential to enhance habitat in systems where instream cover has been lost. Artificial cover units were deployed at eight sites in the Neuse and Tar River basins, and the units collected 30 Carolina Madtoms at two sites in the Tar River basin. Occupancy modeling estimated a Carolina Madtom detection probability of 0.92 using artificial cover units. Compared to other standardized sampling methods, artificial cover units were an efficient passive-sampling technique for detecting Carolina Madtoms. Observations also revealed that artificial cover units were occupied by Carolina Madtoms for reproduction. These findings provide an additional means by which natural resource managers can assess the status of this imperiled species via an inexpensive passive-sampling device that can provide spawning habitat and protection from predators as well as helping to mitigate the effects of instream habitat degradation. *Corresponding author: tkwak@ncsu.edu Present address: Department of Natural Resource Ecology and Management, Iowa State University, 2310 Pammel Drive, 339 Science Hall II, Ames, Iowa 50011, USA.

Interactive comment on “ Abrupt cold events in the North Atlantic in a transient Holocene simulation

My impression is that many of the features and mechanisms of the cold events described here with the CCSM3 model are actually very similar to those of the decadal cold events in the simulations with the MPI-ESM model in that referred paper. For example, the conspicuous cooling and sea ice expansion around the Labrador Sea, the weakening of the subpolar gyre and the oceanic deep convection shutdown, or the length of the cold events itself. I would add, nonetheless, that the authors are here able
The Dynamics of Complexity, Accuracy, and Fluency: A Longitudinal Case Study of Japanese Learners’ English Writing

In this study I investigated the development of complexity, accuracy, and fluency (CAF) in the English writing of 2 Japanese university students of elementary-tolow-intermediate English proficiency over the course of 1 academic year. Data were analyzed from a dynamic systems theory (DST) perspective using min-max graphs, moving correlation coefficients, and a Monte Carlo analysis. The findings show that (a) the CAF measures followed nonlinear trajectories in their development, (b) they often did not correlate positively with one another, and (c) they sometimes showed signs of improvement during phases of high intravariability. The findings suggest that to understand the developmental trajectories and processes involved in language development more deeply, cross-sectional studies of developmental trends of groups should be supplemented with longitudinal studies that examine language development in individual learners.
Growth performance and wood quality of white jabon (Neolamarckia cadamba) progeny testing at Parung Panjang, Bogor, Indonesia

Abstract. Chaerani N, Sudrajat DJ, Siregar IZ, Siregar UJ. 2019. Growth performance and wood quality of white jabon (Neolamarckia cadamba) progeny testing at Parung Panjang, Bogor, Indonesia. Biodiversitas 20: 2295-2301. The aim of this study was to evaluate the genetic parameters of growth and wood quality in white jabon progeny test at 54 months old in Parung Panjang, Bogor. The 105 half-sib families obtained from 12 provenances were evaluated in a randomized complete block design with five replications. Wood quality was assessed both in a non-destructive way using a pilodyn and by destructive method using wood sample taker. Results indicated that the mean value ranged from 5.10 to 10.15 m for height, 6.67 to 15.30 cm for diameter, 2.30 to 3.62 cm for pilodyn penetration, 0.66 to 0.82 g/cm3 for wood density, 0.33 to 0.50 for specific gravity, and 66 to 111 % for moisture content, respectively. There were significant differences among 105 families for all traits except moisture content. The high heritability estimate was found for height (0.4-0.69) and basic density (0.27-0.59). Applying 80% selection intensity on diameter and leaving 84 best families in each block will produce a high total genetic gain. Pilodyn penetration had negative correlation with diameter, wood density, and specific gravity.
Demazure slices of type $A_{2l}^{(2)}$

We consider a Demazure slice of type A ( 2 ) 2 l , that is an associated graded piece of an infinite-dimensional version of a Demazure module. We show that a global Weyl module of a hyperspecial current algebra of type A ( 2 ) 2 l is filtered by Demazure slices. We calculate extensions between a Demazure slice and a usual Demazure module and prove that a graded character of a Demazure slice is equal to a nonsymmetric Macdonald-Koornwinder polynomial divided by its square norm. In the last section, we prove that a global Weyl module of the special current algebra of type A ( 2 ) 2 l is a free module over the polynomial ring arising as the endomorphism ring of itself.

Elionurus tylophorus (Poaceae: Paniceae: Andropogoneae), a new species from the Kimberley region of Western Australia

Barrett, M.D. & Handasyde, T. Elionurus tylophorus (Poaceae: Paniceae: Andropogoneae), a new species from the Kimberley region of Western Australia. Nuytsia 30: 177–194 (2019). A new annual species, Elionurus tylophorus M.D.Barrett & T.Handasyde, is described in the genus Elionurus Willd. of the grass tribe Andropogoneae. It differs from all previously described Elionurus species in having keels of the lower fertile glumes ornamented with projections, these often terminated by minute solitary bristles, rather than regular cilia lacking projections, or with projections terminated by hair-tufts in other species. It differs further from E. citreus (R.Br.) Benth. and E. purpureus E.J.Thomps. , the only other Australian Elionurus, in having strongly developed fertile glume nerves, rachilla longer and lacking a wing, and presence of lemmas and anthers in the pedicellate spikelet. Elionurus tylophorus is currently known from a single location in the King Leopold Ranges in the central Kimberley region, and has conservation significance. A primary division of Elionurus into two clades is hypothesised based on a preliminary chloroplast gene phylogeny and two morphological synapomorphies, presence of tufted glume hairs and oil streaks.
