PHEROMONE DISRUPTION CONTROLS DOUGLAS-FIR TUSSOCK MOTH (LEPIDOPTERA: LYMANTRIIDAE) REPRODUCTION AT HIGH INSECT DENSITIES
Authors: Sower L. L. , Daterman G. E. , Sartwell C. , Funkhouser W. 
Published: December 2009

AbstractHollow fibers containing synthetic pheromone (Z-6-heneicosen-11-one) were applied by helicopter to six plots of about 8 ha each. Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), had reached such high population levels on the plots that trees in some areas were completely defoliated. Reproduction of the moths was reduced 71 and 81%, respectively, at dosages of 8 and 25 g of pheromone/ha relative to untreated control plots.
AN IMPROVED REARING PROCEDURE FOR THE CARROT RUST FLY (DIPTERA: PSILIDAE) WITH OBSERVATIONS ON LIFE HISTORY AND CONDITIONS CONTROLLING DIAPAUSE INDUCTION AND TERMINATION
Authors: McLeod D.G.R. , Whistlecraft J.W. , Harris C.R. 
Published: December 2009

AbstractCarrot rust fly (CRF), Psila rosae (Fabricius) (Diptera: Psilidae), caged with 2-month-old carrot plants at 20 °C, 50–70% RH, and 16:8 L:D laid an average of 109 eggs per female. With ca. 50% survival from egg to pupae, the rearing procedure yielded a 25 × population increase per generation. The duration of the life cycle at 20 °C was ca. 65 days. Calculated threshold temperatures and degree days above those temperatures necessary for complete development were: eggs, 4.5 °C and 94 degree days (°D); larvae, 2.02 °C and 625 °D; and pupae, 1.47 °C and 374 °D. Larvae collected in the field in fall developed normally when incubated at 22 and 19 °C; ca. 40% of the pupae entered diapause at 16 °C, and 100% at 13 and 10 °C. Fall-collected larvae chilled at 1 °C for ca. 3 months developed normally at all temperatures including those which induced diapause in pupae from unchilled larvae. With laboratory-reared pupae, 100% diapause was induced with > 10 days exposure to 13 or 10 °C. Twenty weeks storage at 1 °C was sufficient to terminate diapause in > 95% of the pupae. The ability of both CRF larvae and pupae to survive cold temperature conditions suggests that 2 separate spring emergence peaks may occur, which could have important implications if the spring flight is to be predicted on the basis of °D accumulations.

PREDATION ON PUPAE OF THE SPRUCE BUDWORM (LEPIDOPTERA: TORTRICIDAE) ON THE FOREST FLOOR
Authors: Kelly Brett , Régnière Jacques 
Published: December 2009

AbstractPredation on spruce-budworm, Choristoneura fumiferana (Clem.), pupae on the forest floor was estimated at 72.5% per day. It is unlikely that many adults of the spruce budworm emerge from the forest floor and there would be little bias introduced in the estimation of apparent fecundity by disregarding pupae on the ground. There were large seasonal fluctuations in the rate of predation attributable to various predator groups; the overall rate ranged from 66 to 91% per day. Low temperatures had no detectable effect on vertebrate predation, but reduced invertebrate predation; however, this effect is unlikely to result in much variation in survival of pupae on the forest floor.
NEW PLACEMENT OF TANYPUS PALLENS COQUILLETT, 1902 NEC LARSIA PALLENS (COQ.) SENSU ROBACK 1971 (DIPTERA: CHIRONOMIDAE) AND REDESCRIPTION OF THE HOLOTYPE
Authors: Bilyj Bohdan 
Published: December 2009

AbstractThe generic placement of Tanypus pallens Coquillett, 1902 is changed to Conchapelopia s. str., with a redescription given of the male holotype. As a result Conchapelopia (s.s.) gonoides (Subi.) becomes a junior synonym of Conchapelopia (s.s.) pallens (Coq.). The status of Larsia pallens (Coq.) sensu Roback 1971 with its synonymies are discussed.
FOOD PLANT STUDIES FOR THE HALF-WING GEOMETER, PHIGALIA TITEA (CRAMER) (LEPIDOPTERA: GEOMETRIDAE)
Authors: Butler Linda 
Published: December 2009

AbstractDuring 1983, collections and observations of the half-wing geometer, Phigalia titea (Cramer), were made in 2 counties of eastern West Virginia where the species had caused heavy defoliation of hardwoods in the previous 2 years. Larvae were observed on 41 species of host plants in the field. Host–plant evaluations for 69 species were made in the laboratory with 1st-instar larvae. According to criteria of response/developmental time of larvae, 33 plants were categorized as highly acceptable, 12 as acceptable, 20 as unacceptable, and 4 as toxic.

Published: December 2009

AbstractPatients with hepatitis C virus (HCV) infection develop a number of hematologic disorders, with benign and malignant B‐cell proliferations being the most common. HCV‐infected patients are also prone to developing peripheral cytopenias, the etiologies of which are multifactorial and include hypersplenism and/or antiviral medications. Some of these patients may undergo bone marrow biopsy but no study has systematically recorded the bone marrow findings in this patient group. Here, we report on the range of bone marrow findings in 47 adult HCV‐infected patients. These patients, who lacked concurrent human immunodefiency virus (HIV) infection, most commonly presented for a bone marrow biopsy due to abnormal peripheral cell counts. The bone marrow biopsies displayed a range of findings. Dyserythropoiesis, present in 19% of the cases, was the most common finding. Patients with pancytopenia(n = 6), as defined by current World Health Organization standards, were the most likely to have bone marrow abnormalities; two pancytopenic patients had acute myeloid leukemia, and one patient had a primary myelodysplastic syndrome. There was no correlation in bone marrow findings and antiviral medications, MELD score, cirrhosis or splenomegaly, suggesting that the degree of bone marrow dysfunction is independent of stage of HCV. The results of this study suggest that bone marrow biopsy in HCV‐infected patients, even those with features of hypersplenism and/or documented antiviral therapy, can be a valid test for hematologic evaluation, especially for patients with severe pancytopenia and/or sudden alterations in peripheral cell counts.

Systemic AL amyloidosis with acquired factor X deficiency: A study of perioperative bleeding risk and treatment outcomes in 60 patients
Authors: Thompson Carrie A. , Kyle Robert , Gertz Morie , Heit John , Pruthi Rajiv , Pardanani Animesh 
Published: December 2009

AbstractSystemic light‐chain (AL) amyloidosis may be associated with acquired factor X (FX) deficiency and optimal management of this coagulopathy is unknown. We reviewed our experience with 60 patients with isolated FX deficiency (≤50%) due to AL amyloidosis that underwent an invasive procedure between 1975 and 2007. They were classified as having severe (<10%; n = 6), moderate (10–25%; n = 15), or mild (26–50%; n = 39) FX deficiency. The patients underwent a total of 112 procedures, 19 (17%) of which were managed with periprocedural treatment with one or more hemostatic agents. There were complications in 14 (13%) procedures (bleeding = 12, thrombosis = 1, death = 1). Baseline FX level was not predictive of bleeding risk; the only association with postintervention bleeding was central venous catheter placement. However, bleeding complications were relatively infrequent, particularly in patients with mild or moderate FX deficiency undergoing nonvascular procedures. Activated recombinant factor VII might be considered in patients undergoing major surgical procedures, but further experience is needed. Optimal management of AL patients with FX deficiency undergoing invasive procedures remains to be determined. Am. J. Hematol., 2010. © 2009 Wiley‐Liss, Inc.
Sex and age differences in juvenile social priorities in female philopatric, nondespotic blue monkeys
Authors: Cords Marina , Sheehan Michael J. , Ekernas L. Stefan 
Published: December 2009

AbstractJuveniles should choose social partners on the basis of both current and future utility. Where one sex is philopatric, one expects members of that sex to develop greater and sex‐typical social integration with group‐mates over the juvenile period. Where a partner's position in a dominance hierarchy is not associated with services it can provide, one would not expect juveniles to choose partners based on rank, nor sex differences in rank‐based preferences. We tested these ideas on 39 wild juvenile (3.2–7.4 years) blue monkeys (Cercopithecus mitis stuhlmanni), cercopithecines with strict female philopatry and muted hierarchies. We made focal animal observations over 6 months, and computed observed:expected amounts of proximity time, approaches and grooming given to various social partners. Overall, our results agree with the hypothesis that juvenile blue monkeys target social partners strategically. Spatial proximity, approaches and active grooming showed similar patterns regarding juvenile social preferences. Females were far more sociable than males, groomed more partners, reciprocated grooming more frequently, and preferred—while males avoided—infants as partners. Older juveniles (5–7 years) spent more time than younger juveniles (3–4 years) near others, and older females were especially attracted to infants. Close kin, especially mothers and less consistently adult sisters, were attractive to both male and female juveniles, regardless of age. Both sexes also preferred same‐sex juveniles as social partners while avoiding opposite‐sex peers. Juveniles of both sexes and ages generally neither preferred nor avoided nonmaternal adult females, but all juveniles avoided adult males. Partner's rank had no consistent effect on juveniles' preference, as expected for a species in which dominance plays a weak role. Juveniles' social preferences likely reflect both future and current benefits, including having tolerant adult kin to protect them against predators and conspecifics, same‐sex play partners, and, for females, infants on which to practice mothering skills.

Genetic diversity of two haploid markers in the Udegey population from southeastern Siberia
Authors: Jin Han‐Jun , Kim Ki‐Cheol , Kim Wook 
Published: December 2009

AbstractThe Udegeys are a small ethnic group who live along the tributaries of the Amur River Basin of southeastern Siberia in Russia. They are thought to speak a language belonging to a subdivision of the Tungusic‐Manchu branch of the Altaic family. To understand the genetic features and genetic history of the Udegeys, we analyzed two haploid markers, mitochondrial DNA (mtDNA), and Y‐chromosomal variation, in 51 individuals (including 21 males) from the Udegey population. In general, the Udegeys' mtDNA profiles revealed similarities to Siberians and other northeastern Asian populations, although a moderate European contribution was also detected. Interestingly, pairwise values of FST and the MDS plots based on the mtDNA variation showed that the Orok and Nivkh inhabiting the very same region of the Udegey were significantly different from the Udegey, implying that they may have been isolated and undergone substantial genetic drift. The Udegeys were characterized by a high frequency (66.7%) of Y chromosome haplogroup C, indicating a close genetic relationship with Mongolians and Siberians. On the paternal side, however, very little admixture was observed between the Udegeys and Europeans. Thus, the combined haploid genetic markers of both mtDNA and the Y chromosome imply that the Udegeys are overall closest to Siberians and northeast Asians of the Altaic linguistic family, with a minor maternal contribution from the European part of the continent.

Bed depth service time model for the biosorption of reactive red dye using the Portunus sanguinolentus shell
Authors: JagadeeshBabu P.E. , Krishnan Ram , Singh Mandeep 
Published: December 2009

AbstractBiosorption is an efficient and regenerative technique that often uses low‐cost adsorbent materials, particularly for the treatment of wastewaters containing dyes and heavy metals. This study investigates the ability of crab shell (Portunus sanguinolentus) to remove reactive red dye in a packed bed up‐flow column (internal diameter 2 cm; height 35 cm). Crab shell has high surface area (after proper size reduction) and high regenerative capacity. The experiments were performed with different bed heights (20 and 30 cm) and using different flow rates (12 and 17 ml/min) in order to obtain experimental breakthrough curves. The bed depth service time (BDST) model was used to analyze the experimental data and the model parameters were evaluated. The column regeneration studies were carried out for five different sorption–desorption cycles. The elutant used for the regeneration of the sorbent was 0.01 M EDTA (disodium) solution at pH 9.8 adjusted using NH4OH. This solution was found to have the best bed regeneration capacity and could be reused for several sorption–desorption cycles. The elution efficiency was greater than 99.1% in all seven cycles. Continuous use of the crab shell leads to a decrease in the adsorptive performance, as observed by the breakthrough curves becoming flatter and also because of a broader mass transfer zone.

Development of a hybrid support vector machine and genetic algorithm model for regime identification of slurry transport in pipelines
Authors: Lahiri Sandip Kumar , Ghanta Kartik Chandra 
Published: December 2009

AbstractFour distinct regimes (namely sliding bed, saltation, heterogeneous suspension, and homogeneous suspension) were found existent in slurry flow in a pipeline depending upon the average velocity of flow. In the literature, a few numbers of correlations have been proposed for identification of these regimes in slurry pipelines.Regime identification is important for slurry pipeline design as it is the prerequisite to apply different pressure drop correlations in different regimes. However, available correlations fail to predict the regime over a wide range of conditions. Based on a databank of around 800 measurements collected from the open literature, a method has been proposed to identify the regime using support vector machine (SVM) modeling. The method incorporates hybrid support vector machine and genetic algorithm technique (SVM‐GA) for efficient tuning of SVM meta‐parameters. Statistical analysis showed that the proposed method has an average misclassification error (AARE) of 0.03%. A comparison with selected correlations in the literature showed that the developed SVM‐GA method noticeably improved prediction of regimes over a wide range of operating conditions, physical properties, and pipe diameters.

Preparation and evaluation of novel blend microspheres of poly(lactic‐co‐glycolic)acid and pluronic F68/127 for controlled release of repaglinide
Authors: Shelke Namdev B. , Rokhade Ajit P. , Aminabhavi Tejraj M. 
Published: December 2009

AbstractThe objective of the present work was to study the release behavior of plain and blend microspheres (MS) of PLGA and Pluronic F68/127. In this study, a novel blend MS of poly(D,L‐lactic‐co‐glycolic acid) (PLGA) and Pluronic F68/127 (PLF68/127) were prepared by the emulsion–solvent evaporation method. Repaglinide, an antidiabetic drug with a very short half‐life, was successfully encapsulated into the blend MS. Various formulations were prepared by varying the ratio of PLGA and PLF68/127. Drug encapsulation up to 91% was achieved as measured by UV spectroscopy. Scanning electron microscopy showed that MS have smooth surfaces even after incorporation of PLF68/127. Particle size, as measured by using laser light scattering technique, gave an average size ranging from 12 to 47 μm. Differential scanning calorimetry (DSC) was performed to understand the crystalline nature of the drug after encapsulation into MS. DSC revealed the crystalline dispersion in the polymer matrix. In vitro release experiments performed in simulated intestinal fluid, indicated the dependence of release rate on the amount of PLF68/127 present in the MS; slow release was extended up to 153 h. Release data have been fitted to an empirical equation to compute the diffusional exponent (n), which indicated that the release mechanism to be non‐Fickian type. © 2009 Wiley Periodicals, Inc.

Effect of surface treatment on the properties of polypropylene/nanoboehmite composites
Authors: Bravet David , Guiselin Olivier , Swei Gwo 
Published: December 2009

AbstractBoehmite nanoparticles are surface modified with alkyl phosphorous acid to improve their dispersion in polypropylene. Effective grafting is evidenced by NMR, elemental analysis and by the fact that the dispersion ability (or disagglomeration) of grafted boehmite particle in nonpolar solvent is significantly altered. High dispersibility level in PP is obtained with long alkyl chain surface modifiers. The improvement of the nanocomposites thermal stability is correlated with the nanoparticles dispersion level. However, composite with well dispersed nanoparticle did not demonstrate enhanced mechanical properties because of weak polymer/filler interactions with the PP matrix. Better reinforcement is noticed for polypropylene composite loaded with untreated boehmite or treated with shorter alkyl chain. For these composites, the nanoparticles acted as nucleating agents. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Kinetics of thermal degradation studies of some new terpolymers derived from 2,4‐dihydroxypropiophenone, oxamide, and formaldehyde
Authors: Tarase Mangesh V. , Zade Anil B. , Gurnule Wasudeo B. 
Published: December 2009

AbstractThe terpolymers (2,4‐DHPOF) have been synthesized by the condensation of 2,4‐dihydroxypropiophenone with oxamide and formaldehyde in the presence of 2M HCl as catalyst with varying proportions of reactants. Terpolymer composition has been determined on the basis of their elemental analysis. The terpolymer has been characterized by UV‐visible, IR, and 1H NMR spectra. The thermal decomposition behavior of some new terpolymers was studied using thermogravimetric analysis in air atmosphere at heating rate of 10°C/min. Thermal decomposition curves are discussed with careful attention to minute details. The Freeman–Carroll and Sharp–Wentworth methods have been used to calculate activation energy and thermal stability. Thermal activation energy (Ea) calculated with the help of these methods are in agreement with each other. Thermodynamic parameters such as free energy change (ΔF), entropy change (ΔS), apparent entropy change (S*), and frequency factor (z) are also determined on the basis of the TG curves and by using data of the Freeman–Carroll method. The Freidman method evaluated the variation in the apparent activation energy changes by isoconversional (model‐free) kinetic methods. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Electrical and mechanical properties of carbon nanotube‐epoxy nanocomposites
Authors: Thakre Piyush R. , Bisrat Yordanos , Lagoudas Dimitris C. 
Published: December 2009

AbstractIn this work, electrical conductivity and thermo‐mechanical properties have been measured for carbon nanotube reinforced epoxy matrix composites. These nanocomposites consisted of two types of nanofillers, single walled carbon nanotubes (SW‐CNT) and electrical grade carbon nanotubes (XD‐CNT). The influence of the type of nanotubes and their corresponding loading weight fraction on the microstructure and the resulting electrical and mechanical properties of the nanocomposites have been investigated. The electrical conductivity of the nanocomposites showed a significantly high, about seven orders of magnitude, improvement at very low loading weight fractions of nanotubes in both types of nanocomposites. The percolation threshold in nanocomposites with SW‐CNT fillers was found to be around 0.015 wt % and that with XD‐CNT fillers around 0.0225 wt %. Transmission optical microscopy of the nanocomposites revealed some differences in the microstructure of the two types of nanocomposites which can be related to the variation in the percolation thresholds of these nanocomposites. The mechanical properties (storage modulus and loss modulus) and the glass transition temperature have not been compromised with the addition of fillers compared with significant enhancement of electrical properties. The main significance of these results is that XD‐CNTs can be used as a cost effective nanofiller for electrical applications of epoxy based nanocomposites at a fraction of SW‐CNT cost. © 2009 Wiley Periodicals, Inc.

β‐Cyclodextrin stabilized on three‐dimensional polyester fabric with different crosslinking agents
Authors: Montazer M. , Jolaei M. M. 
Published: December 2009

AbstractThe stabilization of β‐cyclodextrin (β‐CD) on spacer polyester fabric (three‐dimensional) is an interesting task. Using a crosslinking agent to stabilize β‐CD on the spacer polyester fabric is necessary. This causes an increase in the durability of β‐CD on the fabric. In this research, five different crosslinking agents, including two non‐formaldehyde crosslinking agents (citric acid and 1,2,3,4‐butane tetracarboxylic acid), one formaldehyde‐based crosslinking agent (dimethylol dihydroxyl ethylene urea), and two different commercial siloxane‐based softeners, were used to specify the best yield on the polyester spacer fabric with β‐CD. The results showed that, among the different crosslinking agents, 1,2,3,4‐butane tetracarboxylic acid provided the best durability after 10 washings. The changes in the weight, regain, drop absorption time on the fabric surface, metal‐ion (chrome) absorption, and reactive‐dye absorption were also reported, and scanning electron microscopy pictures were observed. © 2009 Wiley Periodicals, Inc.
