Stylet Penetration and Feeding Sites of Rhopalosiphum maidis (Homoptera: Aphididae) on Two Growth Stages of Maize

Stylet penetration and feeding sites of Rhopalosiphum maidis (Fitch) were observed on the seedling stage (Plumule to V1) and the late whorl stage of (V15) maize inbred B96 ( Zea mays L.). Fifty-seven percent of R. maidis stylets entered plants in the late whorl stage through stomata, whereas only 8% of the R. maidis penetrated seedling-stage plants through stomata. The majority of aphids (86%) penetrated seedling plants intercellularly between epidermal cells. Phloem was the preferred feeding site in seedling-stageplants (79%) and plants in the late whorl stage (57%) as indicated by stylet track terminations. In seedling maize, 13% of all stylet tracks had multiple branches, whereas 22% of the stylet tracks in the late whorl stage had multiple branches.
The relevance of sexual biographies in individuals convicted of child sexual abuse offenses for the development of pedosexual interests and sexual recidivism

In the literature concerning the etiology of pedosexual interests, the potential role of early sexual experiences in childhood and adolescence has been discussed. Several studies demonstrated a link between own sexually abusive experiences in childhood and sexual offending later in life which tends to be even stronger for pedosexual offenders. Furthermore, some findings indicate associations between other developmental factors and deviant sexual interests in adulthood. For the present study, sexual biographical data of N = 223 imprisoned men convicted of sexual offenses against children from Austria was analyzed to retrospectively examine whether own sexually abusive experiences and non-abusive forms of early sexual experiences and behaviors are linked to subsequent pedosexual interests and to sexual recidivism. Previous findings concerning the link between own sexually abusive experiences during childhood and subsequent pedosexual interests could partly be replicated. Furthermore, early masturbation behavior characteristics as well as non-abusive prepubescent sexual experiences were linked to indicators of pedosexual interests and also to sexual recidivism. Exclusively pedophilic men showed the strongest accumulation of early sexual experiences and behaviors. Implications of the findings for theory and risk assessment are discussed.
Otolith Staining by Oral Administration of Alizarin Complexon for Juveniles of the Japanese Flounder Paralichthys olivaceus.

Otolith staining by alizarin complexon (ALC) was investigated to develop a new mass-marking method using oral administration in juveniles of the Japanese flounder Paralichthys olivaceus. Fishes of about 50mm in total length (82 days after hatching) were accommodated in three 500l tanks, and were supplied artificial diets treated with ALC solutions (ALC diet) for 15 days. ALC concentrations were 100, 500, and 1, 000mg/kg diet. Fishes were sampled every 5 days during the 15 days of ALC diets and then every month. Otoliths (sagittae) were photomicroscopically observed under G-exited UV light. A clear fluorescent mark was found on the peripheral zone of otoliths dissected immediately after ALC diet treatment, irrespective of the concentration. Otoliths taken from fishes with 1, 000mg-15 days treatment were most clearly stained. Fluorescent marks were not found in ctenoid scales on the ocular body side of the same fish. the fluorescent marks on the otoliths were evidently retained for 119 days of post-treatment at all three concentrations. These results indicate that otolith marking by oral ALC administration is effective and practical as a mass-tagging method in juveniles of Japanese flounder.
Evolution of Mechanical Properties of Carbon Anodes during Baking

To be considered as a good quality product, carbon anodes must not only have a low electrical resistivity, but also a high mechanical resistance to crack generation and propagation. To obtain such anodes, a good understanding of the evolution of their mechanical properties during baking is crucial. Traditional mechanical characterization approaches consist of baking anode samples at specific temperatures and performing the tests at either room temperature or slightly lower than that of the baking level. In the latter case, it is well-known that numerous chemical reactions take place during the tests which affect the results. In this paper, an innovative approach is proposed to ensure the reliability of mechanical properties measurements. The anode cores were taken from industrial green anodes removed directly from the production line of Aluminerie Alouette Inc. (AAI) and then baked to different temperatures in a laboratory furnace of the UQAC/AAI Chair. Compression tests initially performed using the Gleeble system showed that this system was not suitable for low temperature testing, at which the anode samples were in a semi-solid state. To overcome this problem, a new setup was installed on a classical CRIMS press which accurately measures the Young’s modulus, compressive strength, and particularly, Poison’s ratio.
Acute and early HIV infection screening among men who have sex with men, a systematic review and meta‐analysis

Screening for acute and early HIV infections (AEHI) among men who have sex with men (MSM) remains uncommon in sub‐Saharan Africa (SSA). Yet, undiagnosed AEHI among MSM and subsequent failure to link to care are important drivers of the HIV epidemic. We conducted a systematic review and meta‐analysis of AEHI yield among MSM mobilized for AEHI testing; and assessed which risk factors and/or symptoms could increase AEHI yield in MSM.
Pollen-climate distance surfaces and the interpretation of fossil pollen assemblages from the western interior of Canada

A new technique for reconstructing climate from fossil pollen records using mathematical distance surfaces produced in climatic space is outlined. The distance surfaces present the following information: the relationship between modern climatic parameters, vegetation and pollen deposition; the degree of dissimilarity between modern and fossil pollen assemblages; estimates of past climatic conditions based on the numerical comparison of modern and fossil pollen assemblages
Sex-related variation in morphology of helmeted guineafowl (Numida meleagris) from the Riemland of the northeastern Free State, South Africa

In the hope of developing a relatively simple, nondestructive way of sexing adult helmeted guineafowl (Numida meleagris) , sexual differences in body mass and in the size of head adornments of adult helmeted guineafowl sampled during the winter months in the Riemland district of the northeastern Free State, South Africa, were investigated. Males have statistically significantly larger values for all attributes than do females. However, no single attribute, nor a combination of them, can be used to sex guineafowl unambiguously.
Feeding Barki Sheep in South Sinai on Some Agro-Industrial By-Products By Using Combined Biological Treatments تغذیة أغنام البرقى فى جنوب سیناء على بعض مخلفات التصنیع الزراعى باستخدام المعاملات البیولوجیة المتحدة

Effect of using two by-products (sugar beet pulp and date seeds) untreated or biologically treated with different combinations of fungi, bacteria and yeast in sheep feeding on digestibility coefficients, rumen fermentations and rumen microbes, and blood biochemicals was investigated. The study included laboratory experiment, digestibility trail and in vitro gas production. Digestibility trail included six experiments: T (1): Concentrate feed mixture (CFM) + berseem hay (BH) (Control). T (2): CFM contained untreated sugar beet pulp (SBP) and date seeds (DS) + BH. T (3): CFM contained SBP and DS treated with T. virideand S. cerevisiae + BH. T (4): CFM contained SBP and DS treated with T. viride and C. cellulasea + BH. T (5): CFM contained SBP and DS treated with C.cellulasea and S. cerevisiae+ BH. T (6): CFM contained SBP and DS treated with T. viride with C. cellulasea and S. cerevisiae+ BH. Biological combination treatments improved chemical analysis and fiber constituents, while reduced anti-nutritional factors of DS. T6, T4, T3 and T5 increased (P<0.05) digestibility coefficients, nutritive values, nitrogen utilization, microbial protein, rumen fermentations parameters and microbes numbers, gas production at different incubations times and blood serum total proteins and albumin were improved (P<0.05) in T6, T4, T3 and T5, respectively, compared with control and untreated groups. Control group showed higher values than untreated group. Inclusion of sugar beet pulp and date seeds untreated or treated with biological treatments to replace a part of 70% of common concentrate feed mixture had remarkable improved influence on sheep feeding.
Length-Weight Relationships, Morphometric Characteristics and Thorniness of Thorny Skate (Raja radiata) from the Northwest Atlantic

Research on length-weight, morphometries and thorniness of thorny skate in the Northwest Atlantic was carried out in 1947 -72. Length-weight data for the northern and southern regions, where sexual maturity begins at smaller and larger sizes respectively, were compared by sex and maturity. Slopes of the log-log length-weight regressions were lower for matures than for immatures, and, consequently, mature fish had lower average weights than immatures of the larger size-groups. Morphometric characteristics by sex and maturity, as percentages of total length of fish, indicated that tail length was shorter than disc length in mature skate, and that length from snout to posterior tip of pelvic fin was greater, and head width across mid-pupils and distance between the fifth pair of gill slits were less in mature males than in mature females, immature males and immature females. Dorsal thorniness decreased with increase in skate length and advance toward sexual maturity, with males showing a much greater and earlier loss of thorniness than females. Thorniness decreased at smaller sizes in northern waters, where sexual maturity occurs at small sizes, than in southern waters, where sexual maturity occurs at larger sizes.
Prediction of Metabolic Pathway Using Graph Property, Chemical Functional Group and Chemical Structural Set

In systems biology, it is a great challenge for researchers to identify whether the given set of organic compounds can combine together and form a meaningful pathway. Fortunately, it becomes more and more feasible to address and solve such a problem with the rapidly accumulated information on various organisms. Based on the attainable information, a novel computational approach is proposed to investigate this problem by adopting the metabolic pathway of yeast as the subject of the study. And we produced a benchmark dataset with 13,736 pathways consisting of both valid and invalid pathways and identified the valid pathways among them. Each of these pathways was encoded into a numeric vector, consisting of three parts: graph property, chemical functional group, and chemical structural set. Methods of Minimum Redundancy Maximum Relevance and Incremental Feature Selection were utilized to select an optimal feature set, and Nearest Neighbor Algorithm was adopted as the classification model, while Jackknife Test was used to evaluate the model. As a result, an optimal feature set consisting of 16 features, which were able to identify the valid pathways most successfully, was obtained.
GENETIC DIVERSITY IN POPULATIONS OF CISTOPUS SP. BASED ON THE SEQUENCES OF MITOCHONDRIAL 16S rRNA AND COI GENE FRAGMENTS

Sequences of 16S rRNA and COⅠ gene fragments in mtDNA of Cistopus sp.were studied.The samples were collected from five populations in the East China Sea.The sequences were compared by PCR.Nucleotide sequences of 497—501bp for 16S rRNA gene and 652bp for COⅠ gene were obtained.A high percentage of A+T base composition in the two sequences was observed.The alignment indicated that the variation level of intra-stocks was very low in both genes.Eight variable sites were detected for 16S rRNA gene fragment(of which seven were indels) across the five stocks.21 polymorphic sites were detected in COⅠ gene fragments among the five stocks,with no indels.The NJ and UPGMA phylogenetic trees showed that no remarkable genetic difference was observed among those populations.
Stress and adhesion of B4C films for boron-coated neutron detectors

As an alternative to He neutron detectors, boron-coated neutron detectors have been a current focus for researchers worldwide. For the boron-coated neutron detectors, a B4C film with low stress and good adhesion to the Al substrate is required. To enhance adhesion of the B4C films on Al substrates, a B4C film with low stress was fabricated by direct current sputtering technique without substrate-heating. The Mg -Al alloy thin film was introduced between the B4C film and its substrate for enhancing the adhesion. The effect of sputtering pressure on the stress of B4C films during deposition was studied. Additionally, the adhesion of B4C films using Mg-Al films as adhesive layers and effects of sputtering pressure and alloy film thickness on adhesion were studied. Scanning and transmission electron microscopies were used to characterize the microstructure. Experimental results show that the stress of B4C films decreases and stabilizes when sputtering pressure increases during deposition. Thin and porous Mg-Al films react well with both B4C films and Al2O3 on Al substrates to enhance adhesion of the B4C films, without substrate-heating.

The Association Between Personality Traits, Morphological Traits and Alternative Mating Behaviour in Male Endler's Guppies, Poecilia wingei

Alternative mating behaviour, personality traits and morphological characters are predicted to be correlated. Bolder, larger and more colourful males are expected to preferentially court females, while shy, small and drab-coloured individuals are predicted to sneak copulations. We used males of Endler's guppy, Poecilia wingei, to test this association over a long temporal period (hence including ontogenetic changes) and under two social environments (male-biased and female-biased). We found that personality traits (exploration, boldness, activity) of P. wingei males were highly repeatable across long time spans, but they were not correlated (formed no behavioural syndrome). Male age and social environment had no effect on any personality trait, despite their effects on alternative mating behaviour. Young males with higher activity levels were more likely to attempt sneaking. In older fish, there was an association between orange coloration, courtship and boldness, but this was not observed in young males. Our results suggest that alternative mating behaviour is more flexible than personality traits and is independent of them. Non-colour-based morphological traits (gonopodium length, body length, caudal straps length, dorsal fin length) were not correlated with any particular mating behaviour.
A Subject-Oriented Ontology Development for Information Retrieval Application

- Recently, ontology-based application is an important approach of some researches in several fields of Computer Science. The development of Subject-Oriented Ontology (SOO) may be hard for research groups. However, since SOO can apply to various areas especially for subject-driven researches, research groups are continuing to search for solutions for building it. The paper proposes an approach to develop an SOO based on corpus of scientific papers by building subject trees and semantic relationships among them. Our experiments were tested on the ACM corpus and we have acchieved good results in the first phase.
The Life History of the Slimy Salamander, Plethodon glutinosus, in Florida

PLETHODON glutinosus occurs throughout most of eastern United States. Although not uncommon in most of its range, little is known about its life history. Humphrey (1925) studied the testes of this and other species of salamanders in New York and correlated the condition of these organs with the breeding season. Burger (1937) also studied the testes of plethodontid salamanders in the northeastern United States and made further contributions to the knowledge of seasonal cycles in male Plethodon glutinosus. Bishop (1927) speculated on the life history of this species in western New York. Noble and Marshall (1929) discovered two clutches of eggs in caves in Arkansas and described the eggs and embryos. Fowler (1940) found a female guarding a clutch of eggs in West Virginia, and Bishop (1941) added a few notes on development to maturity. Pope and Pope (1949) studied growth and reproduction in southwestern Virginia, and Pope (1950) recorded a courtship dance in the same region. To my knowledge there have been no studies on the life history of the slimy salamander in the southeastern coastal plain. The purpose of the present study was to obtain detailed information on the life history of Plethodon glutinosus in Florida. Part of the present work was presented to the Graduate Council of the University of Florida in partial fulfillment of the requirements for the degree of Master of Science.
A novel basis for analysis of music

We present a new basis for anal- ysis of music. The basis vectors are sam- pled real waveforms of fixed frequency inside a Gaussian envelope. Their frequencies and time localizations are induced by a tiling of the time-frequency plane well adapted to mu- sic. Through a careful investigation of their properties they are subsequently slightly mod- ified in order to give a stable system, without losing their time-frequency localization. Our new basis discriminates semitones, detects the overtones as well as the attack of notes, and gives a sparse representation of the signal. It will enhance the performance of all kinds of dig- ital audio processors, and provide a useful tool for numerous multimedia applications.

Disease, predator avoidance, and vulnerability to predation in tadpoles

Many parasites alter the behaviour of their hosts. In most systems that have been studied, predation of the intermediate host by the definitive host is necessary for parasite transmission. Directly transmitted parasites have been studied less frequently and the fitness benefits from altering host behaviours that lead to the death of the host are not obvious. We examined the behavioural and ecological effects of the yeast Candida humicola, a directly transmitted parasite species in its natural host, the red-legged frog (Rana aurora). This parasite dies if its host dies. We used a mixture of field and laboratory experiments to test : 1) if infected tadpoles have altered thermal preferences (behavioural fevers), 2) the ability of infected tadpoles to detect and respond to chemical cues from predacious roughskinned newts (Taricha granulosa) and 3) the susceptibility of infected tadpoles to predation by newts. We found that infected tadpoles exhibited altered thermoregulatory behaviour, exhibited reduced ability to differentiate chemical cues of potentially dangerous from innocuous predators, and suffered increased predation. Behavioural by-products of the host response to infection may provide a mechanism by which behavioural alterations occur in some one and two-host parasite systems. Physiological changes associated with the host response to infection fight disease organisms, but behavioural aspects of the response may have negative effects on host survival.
DETECTION OF METALLO BETA - LACTAMASES AMONG ENTEROBACTERIACEAE ISOLATES AT A TERTIARY CARE HOSPITAL, SOUTH INDIA

Background : The spread of carbapenem resistant bacteria has caused grave concern due to the limited choice in antibiotics for treating infections caused by them. The emergence of metallo beta-lactamse (MBL) producing gram negative bacilli poses a therapeutic challenge and is of serious concern for infection control in hospital environment. Materials & Methods: A total of 475 non repeat clinical isolates of family Enterobacteriaceae were included in the study. Resistance to imipenem was determined in isolates by disc diffusion & minimum inhibitory concentration (MIC) method. Imipenem resistant isolates were tested for MBL production by combined disc diffusion test and modified Hodge test. Results: Out of the 475 Enterobacteriaceae strains, 20 showed resistance to imipenem. MBL activity was detected in all 20 (4.2%) isolates by combined disc diffusion test, in 18 isolates by modified Hodge test. The MBL producing isolates included clinical strains of Klebsiella spp (45%), E. coli (40%), Citrobacter spp (15%). Majority of the MBL isolates were from Intensive care unit (65%), from patients with comorbid conditions and with invasive devices. MBL producing isolates showed high level of resistance to aminoglycosides and fluoroquinolones but all were susceptible to colistin. Conclusion : The need of the hour is to detect MBL producing isolates for better patient outcomes, to execute prompt infection control measures and decrease the escalation of resistance.
GREEDY SHORTEST SUPERSTRING WITH DELAYED RANDOM CHOICE

The shortest superstring problem for a given set of strings is to find a string of minimum length such that each input string is a substring of the resulting string. This problem is known to be NP-complete. A simple and popular approximation algorithm for this problem is GREEDY, which at each step merges a pair of strings that have maximum overlap. If more than one pair have maximum overlap, it takes a pair in random. In this paper, we modify GREEDY such that instead of taking a pair in random, it takes the pair for which the overlap in the next step is maximum. We analyze our algorithm and compare it with GREEDY for different types of input. We implement both the algorithms and the experimental results show that our algorithm can outperform GREEDY substantially in many cases, and in general our algorithm is same or better than GREEDY.
A Current-mode DC-DC Boost Converter for Automotive LED Headlamp Driver

This paper proposes a current-mode DC-DC boost converter for automotive LED headlamp driver. Recently, the trends of an evolution of the LEDs composed by huge pixel, instead of a unit of the LEDs. Therefore, the specifications of DC-DC converters would be much important to operate number of LEDs. In this paper, the current-mode boost converter is proposed to have much wider load current range than the conventional voltage-mode control method. Meanwhile, circuit implementations of building blocks for the proposed boost converter are also presented. The proposed converter has been fabricated through TSMC 0.18-μm 60 V BCD process. The converter operates at a 10 MHz high switching frequency.
