Expermental Studies on Snow Crystals of Plane Type with Spatial Branches

Riming experiments of supercooled droplets on the surface of an ice plate of single crystal were made at various temperatures below freezing, and their crystal orientations were observed under a polarization microscope. It was found that the droplets were frozen into single crystal with c-axis parallel to that of the ice plate at temperature regions warmer than -15°C, while the droplets were frozen into poly crystal or single crystal with the c-axis different from that of the ice plate at temperature regions colder than -15°C. Further, artificial snow-making experiments for snow crystals with spatial dendritic branches were made, utilizing such droplets rimed on the ice plate, and it was confirmed that spatial branches developed from the droplets with c-axes different from that of the ice plate. It seemed that larger ones among the rimed droplets acted as nuclei for spatial branches. As a result of the experiments, it was concluded that some of rimed droplets which were frozen to ice surface at temperature regions colder than -15 or _20°C, became nuclei for the spatial branches. This result agrees well with the meteorological condition of natural snow crystals of plane type with spatial dendritic branches.

Spatial and temporal patterns of distribution and abundance of chaetodontid fishes at One Tree Reef, southern GBR

Between November 1984 and April 1987, the butterflyfishes of One Tree Reef on the southern Great Barrier Reef were sampled on 8 occasions at 9 widely dispersed localities across the reef using a hierarchial sampling regime. Data were collected on 23 species which fell into 3 categories of abundance. Three 'abundant' species each contributed > 10 O/O of the total of all individuals. Five species were 'common', each contributing 2 to 10 ";o of the total, and 15 species were 'rare', each contributing < 1.0 % of the total. The 8 'abundant' and 'common' species were present at all localities, whilst 11 of the 'rare' species had restricted and discontinuous distributions. The former 8 demonstrated significant differences in abundance amongst localities, 5 of which also had significant differences amongst sites (within combinations of occasions and localities) Relationships between fish abundance and coral abundance were weak, and could not predict these spatial patterns. The size structures of the 3 abundant species inchcated consistent spatial differences, implying different population dynamics occurring on adjacent and local areas of reef. Five abundant and common species showed significant temporal variation, 2 species showed a seasonal pattern of variation, and 3 species showed increases in population density. Generally, however, spatial differences amongst localities were maintained through time.
Fracture and Fatigue Behavior of Polymer Nanocomposites—A Review

Fiber reinforced polymer (FRP) composites are widely used in structural applications, mainly due to their high specific strength and stiffness. These composites experience several types of static and fatigue loads in service. For a safe and durable structure, high fracture toughness and enhanced fatigue life are prominent requirements of these composite materials. Efforts have been made in recent times to improve the fracture toughness and fatigue properties of FRP composites by incorporation of second phase fillers in the epoxy matrix. Addition of nano sized fillers to the epoxy has led to the development of a new class of materials—polymer nanocomposites. The presence of nano fillers has been shown to improve the fracture toughness and fatigue life of bulk epoxies as well as FRPs with nano-modified epoxy matrix. The type of nano filler, its shape, size, volume fraction and dispersion in the epoxy have all been shown to influence these properties significantly. In this review, an overview on the effect of nano fillers on the fracture toughness and fatigue life of bulk epoxies and FRPs is presented. The mechanisms proposed for observed improvements in these properties and the empirical method of prediction of fatigue life of nanocomposites subjected to spectrum fatigue loads simulating service loads are also discussed.
Sport Commitment Among Adult Recreational Soccer Players: Test of an Expanded Model

International Journal of Exercise Science 10(1): 4-24, 2017. Adult sport leagues provide opportunities for physical activity (PA), but little is known about adults’ commitment to recreational sports. We proposed two expanded versions of Scanlan and colleagues’ sport commitment model (SCM) to explore psychosocial factors related to adults’ participation in these leagues. Model 1 proposed athletic identity and social cohesion as additional predictors of commitment. Previous research found these variables to be positively related to commitment, but had not systematically examined them within the context of the SCM. We also explored participation in moderate-to-vigorous physical activity (MVPA) as a behavioral manifestation of commitment. Model 2 explored athletic identity as a mediator between commitment and MVPA. Adult recreational soccer players (156 females, 196 males; M age = 29.5) completed valid measures following a game. Structural equation modeling revealed enjoyment and investments positively predicted commitment, and psychological commitment to soccer was indirectly related to weekly minutes of MVPA through the perceived importance of PA to self-identity. Players who reported greater enjoyment and invested more resources into participation reported greater resolve to continue playing. Players’ desire to remain involved in soccer reinforced the salience of PA to their identities, which was related to participation in MVPA. This study extends SCM research by examining factors underlying commitment to adult recreational team sports, and by demonstrating sport commitment is related to MVPA. Similar to previous research with elite athletes, the strongest predictors of commitment were enjoyment and personal investments. Further research is needed to examine the proposed link between commitment, athletic identity, and MVPA.

Evaluation of a single probe capacitance meter for estimating herbage yield.

A single probe electronic capacitance meter for estimating herbage yields was geld tested on 2 western wheatgrass (Pawopyrum mithii (Rydb.) Liive), a blue grama (Bouteloua gmcilis (H.B.K.) Lag. ex Griffith@, crested wheatgrass (Agropyron cristutum (L.) Gaertn. ), and Russian wildrye (Psuthrostachys juncea (Fisch.) Nevski) stands in the Northern Great Plains. This single probe meter is lightweight, portable, and allows the user to estimate yields of single plants to determine productivity of individual species. Linear regression equations were fitted between probe readings and the green and dry weight of forage clipped from individual plants within a 78.5cm* circular plot. An overall coefficient of determination (I*) of 0.50 was obtained with linear reiationships being statistically signfficant between the probe readings and green and dry weight of forage for ail regressions (eO.10). Considering the regression estimates for P, standard error of the estimate and F values, the best model fit occurred in the western wheatgrass and crested wheatgrass stands. Presence of a litter mat in 1 western wheatgrass stand had little influence on the precision of the instrument, but phenoiogy of the plants strongly influenced meter readings. Therefore, regression lines within a species could not be pooled across ail sampling dates. Comparing yields of individual species from the small plots of the single probe meter to yields from a larger, 1,858cm* rectangular plot estimated with a multi-probe capacitance meter showed comparfsons were not statistically different 50% of the time. A sample size of approximately 150 plots per species was required for each sample period for the single probe meter.
Investigating pilot’s decision making when facing an unstabilized approach: an eye-tracking study

Unstabilized approach has been identified to be a major causal factor of approach-and-landing accidents (e.g. off-runway touchdowns, hard landing, tail-strikes, etc). We conducted an experiment in order to analyze pilots’ performance during such approaches. Ten type-rated, commercial pilots flew each in a B737 full-flight simulator during an unstabilized approach at Hamburg airport. The Pilot Flyings’ (PF) eye gazes were collected. The results revealed that half of the pilots persisted in an erroneous landing decision. These latter pilots had higher dwell time on the attitude indicator/flight director whereas the group of pilots who perfomed the go-around exhibited more fixations on the navigation display prior to their final decision. These findings indicate that the decision whether to land or to go-around is taken considerably long before the respective task is executed, and that the use of heuristics impair pilot’s performance.
Revisit the Budget Deficits and Inflation: Evidence from Time and Frequency Domain Analyses

The purpose of this paper is to test the relationship between budget deficits and inflation for nine EU countries during the period of 1990-2013 using the quarterly data. Recently, the public deficits and inflation have had an increasing importance for developing/emerging and developed countries to build the stability macroeconomic performance in the long run. This study is the first attempt to determine the relationship between the inflation and budget deficits for nine EU countries using different bootstrap causality tests. We employ the bootstrap causality and Granger causality test in the frequency domain analysis which allows us to distinguish short and long-run causality. We do not find a relationship between these variables when we employ bootstrap causality analysis. While the frequency domain causality shows that there is no relationship causality from budget deficits to inflation for all countries, causality from inflation to budget deficits indicates a permanent (long-run) relationship for Belgium, and France.
Cytotoxicity and genotoxicity of some agropesticides used in Southern Africa

Pesticides use boosts agricultural yield by reducing crop losses. However, some pesticides are mutagens and active ingredients could produce different effects in different formulations. Wipe-out (WO) (Glyphosate 360 g/l), K-O Gard® (KOG) (Deltamethrin 10 g/l), Cutworm bait (CWB) (Sodium Fluosilicate, 100 g/kg), Snail ban (SB) (Metaldehyde, 30 g/kg and Carbaryl, 20 g/kg) and Coopex (CPX) (Permethrin 250 g/kg) were tested for cytotoxicity and genotoxicity using the onion (Allium cepa) test. Onion seeds were germinated and exposed (mg/l) to below EC50 values of WO (78.1, 156.3, 312.5), KOG (156.3, 312.5, 625.0), CWB (78.1, 156.3, 312.5), SB (156.3, 312.5, 625.0), and CPX (312.5, 625.0, 1250.0) for 24 h. Root tips were cut, fixed, hydrolyzed in 1 N hydrochloric acid, stained, squashed and observed microscopically. Cytotoxicity and genotoxicity induction at each treatment was compared with the negative control using t-test. WO (78.1, 156.3, and 312.5), KOG (312.5, 625.0) and CWB (312.5) were cytotoxic, (P < 0.05). WO (78.1, 312.5), CWB (156.3, 312.5), SB (625.0) and CPX (1250.0) induced genotoxicity (P < 0.05), mostly, sticky chromosomes. The genotoxic pesticides have potential to cause adverse environmental and health effects, because most adverse effects by genotoxins result from genetic damage and genotoxicity of chemicals is likely to result from cell division abnormalities. Key words: Allium cepa, agropesticides, Southern Africa, mitotic index, chromosome aberration.
Dung beetle (Scarabaeus (Pachysoma)) biology and immature stages: reversal to ancestral states under desert conditions (Coleoptera: Scarabaeidae)?

The unique feeding biology of the unusual flightless Namib Desert dung beetle species belonging to Scarabaeus (Pachysoma) MacLeay (Scarabaeidae: Scarabaeinae) has been studied in the past but in this report we document breeding biology, larval feeding and immature morphology for the first time. Females provision burrows with fragments of dry herbivore dung and detritus, in which the larvae develop and on which they feed. This is a novel deviation, and a probable reversal to the ancestral state, from the obligatory brood ball constructed from wet dung in which scarab larvae usually develop. The free-living larvae and pupae have several unique attributes that distinguish them from relatives that develop within the confines of a brood ball and provide additional support for monophyly of the group. Many of these also appear as reversals to a probable ancestral condition. Unique larval characters include a left mandible with two teeth, the absence of a ‘coprine’ hump, small spiracles, and two- or indistinctly three-segmented antennae. Those unique to the pupa are the presence of peculiar prothoracic projections, the absence of lateral tergal supporting projections on the abdomen, and the perpendicular elytra and wings relative to the median bodyline. © 2004 The Linnean Society of London, Biological Journal of the Linnean Society, 2004, 83, 453–460.
A novel resonant gate driver for high frequency synchronous buck converters

This paper introduces a new resonant gate driver for both the top and bottom switches of a synchronous buck converter. A coupled inductor is used to reduce the size as well as to transfer energy between the top and bottom gate driving. A possible semiconductor integration approach is proposed for this resonant gate driver based on a self-adaptive control method. Theoretical analysis, simulation and experimental results prove that the proposed driver can greatly reduce the gate driving loss and that it is well suited to high-frequency applications.
The presentation of self in résumés: an intercultural approach

In this paper, résumés in two languages and two cultures, Peninsular Spanish and American English, are analysed. For this qualitative analysis, we have relied on the dual perspective proposed by Flowerdew (2005) which postulates a complementary usage of linguistic and ethnographic approaches to the study of genre. The analysis of discourse is based on tenets of genre analysis (Swales 1990; Unger 2007) which have traditionally constituted a substantial part of the theoretical basis of the LSP field. However, it also introduces tenets from sociolinguistics and pragmatics (Brown & Levinson 1987; Scollon & Scollon 2001) as résumés crucially involve the presentation of self – namely the construction of professional identity of candidates (de Fina et al. 2006; Dyer & Keller-Cohen 2000). The ethnographic approach consists of interviews of recruiters from both cultures to find out what their expectations are relative to applicants’ presentation of selves. The results, although tentative, indicate that cultural expectations in terms of what constitutes an adequate résumé vary between the two cultures, especially with respect to the type of personal information provided and the lexico-syntactic structures that candidates use to distance themselves from their achievements.
A Comparative Study of Effectiveness of Medicinal Therapy and Combined Therapy (Cognitive –Behavioral and Drug) of Students Diagnosed with Attention Deficit Hyperactivity Disorder (ADHD)

Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent disorder affecting 5-10% of children. ADHD is particularly characterized in the start of primary school, making some educational, behavioral, and social problems for the individuals and families. Therefore, this article aimed to study the effectiveness of two methods, drug therapy and combined therapy (cognitive-behavioral and drug). The statistical population consisted of 176 male students aged 7-13 referred to the Consultation Committee in 2015. A total of 45 students diagnosed with ADHD were enrolled as the sample using the convenience sampling method. Data were collected using psychiatric diagnostic interviews and CSI-4 Questionnaires. The students were randomly divided into three 15-member groups. Pretests were employed before any treatment. The independent variable was therapy held in 10 sessions. The dependent variable was ADHD symptoms. The first group underwent drug therapy using Ritalin prescribed by the physician. The second group received combined therapy (Ritalin and cognitive-behavioral therapy (CBT)) using training. Control group had no treatment. A week after treatment, posttest was carried out. The data were analyzed using covariance, ANOVA, and LA-Metric post hoc tests. The results showed that drug and combined therapy were effective (P<0.01 and F 1.41 =118.313). LA-Metric post hoc test showed that both drug therapy (P<0.01) and combined therapy (P<0.01) had a significant relationship with the control group. Drug therapy had no significant relationship with the combined therapy (P> 0.05).
Optimal strategy for polarization modulation in the LSPE-SWIPE experiment

Context. Cosmic microwave background (CMB) B-mode experiments are required to control systematic effects with an unprecedented level of accuracy. Polarization modulation by a half wave plate (HWP) is a powerful technique able to mitigate a large number of the instrumental systematics.Aims. Our goal is to optimize the polarization modulation strategy of the upcoming LSPE-SWIPE balloon-borne experiment, devoted to the accurate measurement of CMB polarization at large angular scales.Methods. We departed from the nominal LSPE-SWIPE modulation strategy (HWP stepped every 60 s with a telescope scanning at around 12 deg/s) and performed a thorough investigation of a wide range of possible HWP schemes (either in stepped or continuously spinning mode and at different azimuth telescope scan-speeds) in the frequency, map and angular power spectrum domain. In addition, we probed the effect of high-pass and band-pass filters of the data stream and explored the HWP response in the minimal case of one detector for one operation day (critical for the single-detector calibration process). We finally tested the modulation performance against typical HWP-induced systematics.Results. Our analysis shows that some stepped HWP schemes, either slowly rotating or combined with slow telescope modulations, represent poor choices. Moreover, our results point out that the nominal configuration may not be the most convenient choice. While a large class of spinning designs provides comparable results in terms of pixel angle coverage, map-making residuals and BB power spectrum standard deviations with respect to the nominal strategy, we find that some specific configurations (e.g., a rapidly spinning HWP with a slow gondola modulation) allow a more efficient polarization recovery in more general real-case situations.Conclusions. Although our simulations are specific to the LSPE-SWIPE mission, the general outcomes of our analysis can be easily generalized to other CMB polarization experiments.
Peristaltic Transport of Viscoelastic Bio-fluids with Fractional Derivative Models

Peristaltic ﬂow of viscoelastic ﬂuid through a uniform channel is considered under the assumptions of long wavelength and low Reynolds number. The fractional Oldroyd-B constitutive viscoelastic law is employed. Based on models for peristaltic viscoelastic ﬂows given in a series of papers by Tripathi et al. (e.g. Appl Math Comput. 215 (2010) 3645–3654; Math Biosci. 233 (2011) 90–97) we present a detailed analytical and numerical study of the evolution in time of the pressure gradient across one wavelength. An analytical expression for the pressure gradient is obtained in terms of Mittag-Lefﬂer functions and its behavior is analyzed. For numerical computation the fractional Adams method is used. The inﬂuence of the different material parameters is discussed, as well as constraints on the parameters under which the model is physically meaningful.
A guideline to nematocyst nomenclature and classification, and some notes on the systematic value of nematocysts*

Cnidocysts, or cnidae, are membrane-enclosed cellular organelles or secretions of the golgi apparatus, consisting of a capsule and an eversible tubule (Slautterback and Fawcett, 1959; Watson and Wood, 1988; Arai, 1997). They have been classified traditionally in two major categories, nematocysts and spirocysts (Bedot, 1896; Weill, 1934) to which a third category, the ptychocyst, has been added (Mariscal et al., 1977, see also Watson and Wood, 1988). Cnidarian systematics have considered types of cnidocysts an important systematic character and have defined the cnidome as the census of cnidocyst present in a species (Weill, 1934). Cnidomes and information on the size and distribution of cnidocysts are now considered an important part of a species’s descriptions (Itô and Inoe, 1962; Kubota, 1976, 1978a,b; Gravier-Bonnet, 1987; Östman, 1983). Spirocysts and ptychocysts are homogeneous categories, each comprising a single type of cnidocyst. Spirocysts are present only in the Anthozoa, whereas ptychocysts are found exclusively in cerianthids. The capsule wall of spirocysts is thin, and the encapsulated tubule is strongly coiled. The everted tubule lacks spines entirely but secretes a unique adhering, hygroscopic substance (K. W. England, unpublished manuscript). The everted tubules of ptychocysts are woven into the cerianthid’s body tube (Mariscal et al., 1977). SCI. MAR., 64 (Supl. 1): 31-46 SCIENTIA MARINA 2000
