Published: January 2010

The following list contains eighty-six species of spiders collected in the Mackenzie District. The greater portion of species were collected in the vicinity of Great Slave Lake; however, a few of these were from Fort Smith, close to the southern boundary of the Mackenzie District, and Great Bear Lake.The collection was made during the summers of 1945, '46 and '47. The major portion of the collection was due to the efforts of Dr. D. S. Rawson, Department of Biology, University of Saskatchewan; Dr. J. G. Oughton, formerly of the Royal Ontario Museum of Zoology, Mr. J. R. Vockeroth of the University of Saskatchewan, and Dr. W. A. Kennedy, of the Biological Board of Canada.
Benzene Hexachloride (BHC) as a Rapid Control Agent for White Grubs (Phyllophaga spp.)
Authors: Hammond G. H. 
Published: January 2010

The effectiveness of benzene hexachloride (BHC) when applied to pasture sod as a control for June beetles was demonstrated (1) during 1947 at Marmora. Tests were continued during 1948 to determine the control value of the same contact insecticide against second-year, second- and third-instar larvae at the summer-feeding level in sod land.A block of field plots was laid out in a pasture which was so severely infested by second-year grubs that it was expected to show most extensive destruction of sod before the end of the summer. It was considered as a most suitable area to determine the efficiency of BHC, in terms of sod protection and white grub mortality.
A novel process for continuous thermal embossing of large‐area nanopatterns onto polymer films
Authors: Fagan Matthew D. , Kim Byung H. , Yao Donggang 
Published: January 2010

AbstractHot embossing and nanoimprinting processes are being widely practiced in industry. Fast and reliable production of micro/nanofeatured patterns on large‐area polymer films is of a great importance. In this study, a novel roll‐to‐roll thermal imprinting process was developed, capable of providing a mold‐heating rate of 125°C/s with sufficient temperature control to produce large‐area patterns continuously at a rapid production rate. With this new process, selected micro/nano patterns were produced on a polyethylene terephthalate film at a production rate exceeding 1 m/min. The roller mold temperature played a profound role in affecting the replication quality. To achieve good feature transfer properties, an elevated roller mold temperature approaching the melting temperature of the polymer was found to be critical. Microcavity filling time calculation further revealed that the elevated roller mold temperature is also necessary for achieving a rapid film feed rate as desired in the continuous roll‐to‐roll process. © 2010 Wiley Periodicals, Inc.

Authors: Jagadish R. S. , Raj Baldev , Srinivas P. 
Published: January 2010

AbstractIn this investigation, modification of polypropylene (PP) with an objective to obtain packaging film with improved gas barrier properties has been studied. The chemical reaction of PP resin with hexamethylene diisocyanate and toluene diisocyanate was monitored by Fourier transform infrared spectroscopy, wherein the appearance of new peaks at 3333 cm−1 for NH stretching, 1620–1641 cm−1 for (CO)NH stretching and 1552–1578 cm−1 corresponding to NH bending in an amide moiety was observed for both the modified PP films. Films of excellent clarity and uniform thickness were obtained by the extrusion of cross‐linked polypropylene. The barrier, mechanical, optical, and thermal properties of the modified PP films were studied. The results clearly indicated significant changes in gas barrier and mechanical properties. Food compatibility of the films was evaluated by overall migration in to different food simulants. © 2010 Wiley Periodicals, Inc.

The effect of column diameter and bed height on minimum fluidization velocity
Authors: Rao Akhil , Curtis Jennifer S. , Hancock Bruno C. , Wassgren Carl 
Published: January 2010

AbstractExperiments show that the minimum fluidization velocity of particles increases as the diameter of the fluidization column is reduced, or if the height of the bed is increased. These trends are shown to be due to the influence of the wall. A new, semicorrelated model is proposed, which incorporates Janssen's wall effects in the calculation of the minimum fluidization velocity. The wall friction opposes not only the bed weight but also the drag force acting on the particles during fluidization. The enhanced wall friction leads to an increase in the minimum fluidization velocity. The model predictions compare favorably to existing correlations and experimental data. © 2010 American Institute of Chemical Engineers AIChE J, 2010
Darcy's law‐based model for wicking in paper‐like swelling porous media
Authors: Masoodi Reza , Pillai Krishna M. 
Published: January 2010

AbstractThe wicking of liquid into a paper‐like swelling porous medium made from cellulose and superabsorbent fibers was modeled using Darcy's law. The work is built on a previous study in which the Washburn equation, modified to account for swelling, was used to predict wicking in a composite of cellulose and superabsorbent fibers. In a new wicking model proposed here, Darcy's law for flow in porous media is coupled with the mass conservation equation containing an added sink or source term to account for matrix swelling and liquid absorption. The wicking‐rate predicted by the new model compares well with the previous experimental data, as well as the modified Washburn equation predictions. The effectiveness of various permeability models used with the new wicking model is also investigated. © 2010 American Institute of Chemical Engineers AIChE J, 2010
Overall efficiency evaluation of commercial distillation columns with valve and dualflow trays
Authors: Domingues T. L. , Secchi A. R. , Mendes T. F. 
Published: January 2010

AbstractThe main objective of this work is to establish appropriated ways for estimating the overall efficiencies of industrial distillation columns with valve trays with downcomer and dualflow trays. The knowledge of efficiencies has fundamental importance in the design and performance evaluation of distillation columns. Searching in the literature, a tree of alternatives was identified to compose the tray efficiency model, depending on the mass transfer models, the liquid distribution and vapor flow models on the tray, the liquid entrainment model, the multicomponent mixture equilibrium model, the physical properties models, the height of froth on the tray model and the efficiency definition. In this work, different methods to predict the overall efficiency of distillation columns with valve and dualflow trays were composed and compared with data from three commercial distillation columns under different operating conditions. The models were inserted in the Aspen Plus 12.1 simulator, in Fortran language, together with tray geometrical data, fluid properties and operating data of the distillation columns. For each column, the best thermodynamic package was chosen by checking the temperature profile and overhead and bottom compositions obtained via simulation against the corresponding actual data of industrial columns. A modification in the fraction of holes evaluation that is jetting parameter of the Garcia's hydraulic model of dispersion above the tray was proposed. This modification produced better results than the original model to predict the fraction of holes that are jetting and in the efficiency of dualflow trays and similar results to Garcia model in the efficiency evaluation of valve trays. © 2010 American Institute of Chemical Engineers AIChE J, 2010

Authors: Wu Jun , Xu Zhengwen , Zhang Weiming , Lv Lu , Pan Bingcai , Nie Guangze , Li Minghui , Du Qiong 
Published: January 2010

AbstractAminated resin (NDA‐101) and oxidized resin (NDA‐702) were synthesized to remove Dimethyl phthalate (DMP) from the contaminated water. The equilibrium and heat properties in the course of adsorption process were examined and compared with two commercial heterogeneous adsorbents, namely an acrylic ester resin (Amberlite XAD‐7) and a coal‐based granular activated carbon (AC‐750). The associated equilibrium isotherms can be well fitted by Freundlich equation and the adsorption capacities for DMP followed the order: NDA‐702 > NDA‐101 > AC‐750 > XAD‐7. The surface of XAD‐7 was demonstrated to be relatively homogeneous through surface energy heterogeneity analysis, offering the sole hydrogen bonding interaction. Contrarily, heterogeneous surface of oxidized resins NDA‐702 and the aminated resins NDA‐101 exhibited a promising adsorption capacity and affinity toward DMP probably derived by multiple hydrogen bonding, π–π stacking, and micropore filling interactions. © 2010 American Institute of Chemical Engineers AIChE J, 2010
Prediction of vapor–liquid equilibrium for polymer solutions based on the COSMO‐SAC model
Authors: Yang Li , Xu Xiaochun , Peng Changjun , Liu Honglai , Hu Ying 
Published: January 2010

AbstractTo extend the application of the COSMO‐SAC model to phase‐equilibrium calculations of polymer solutions, a new strategy for estimating the charge‐density profile, the cavity volume and the cavity surface area of polymer molecules is proposed by finding reasonable parameters for the corresponding repeating structure units. The molecular parameters for polymers are obtained by summing up the corresponding COSMO calculated values of the repeating units calculated by the algorithms of DMol3 (a density functional theory) or MOPAC (a semi‐empirical method). Combining with the COSMO‐SAC model, the activities and equilibrium pressures for several typical polymer solutions are satisfactorily predicted indicating that the proposed method can be used for the prediction of vapor–liquid equilibrium of polymer solutions. It was also found that both DMol3 and MOPAC can be used though the results obtained from them are slightly different. The results in this paper show that the method proposed has the potential to predict other phase‐equilibrium properties of polymer systems. © 2010 American Institute of Chemical Engineers AIChE J, 2010
Density segregation in vibrated granular beds with bumpy surfaces
Authors: Lim Eldin Wee Chuan 
Published: January 2010

AbstractSegregation of granular materials by virtue of density or size is a commonly encountered phenomenon in nature. Despite its widespread interest among many researchers in recent years, a complete and unified understanding of granular segregation remains elusive to date. Using molecular dynamics simulations, we report a novel technique of inducing density segregation in a binary mixture of granular materials subjected to vibrations by the use of a bumpy vibrating base. Density segregation in the vertical directions may be induced by oscillating the bumpy base composed of discrete solid particles vertically or horizontally. In both cases, lighter particles tended to rise to the top of the granular bed and form a layer above the heavier particles. We suggest that differences in granular temperature profiles arising from the two different modes of vibrations may play an important role in determining the extent of density segregation occurring in binary granular mixtures. © 2010 American Institute of Chemical Engineers AIChE J, 2010
Molecular dynamics simulation of desulfurization by ionic liquids
Authors: Liu Xiaomin , Zhou Guohui , Zhang Xiangping , Zhang Suojiang 
Published: January 2010

AbstractIonic liquids (ILs) have shown an excellent performance for removing the sulfur compounds of fuel. In this work, molecular dynamic simulations were performed to screen suitable IL instead of the traditional method which is inefficient. DBT and DBTO2 were used as model compounds to study the mechanism of desulphurization. An all‐atom force field was proposed for dibenzothiophene (DBT) and dibenzothiophene 5,5‐dioxide (DBTO2). The calculated results are in good agreement with the experimental value. We investigated the interaction between the model compounds and a series of ILs composed of 1‐alkyl‐3‐methylimidazolium cations ([Cnmim]+, n = 4, 6, 8, 10) and BF, PF anions. We found that the interaction between hydrogen atoms in imidazolium ring and oxygen atoms in DBTO2 is stronger than that of sulfur atoms in DBT, and it means that DBTO2 is extracted by ILs more easily than DBT. In this work, we also compared and discussed the desulphurization mechanism as a function of different ILs, sulfur contents, temperatures, and inclusion of water or not. The above results may help us design extractant and improve the operating conditions. © 2010 American Institute of Chemical Engineers AIChE J, 56: 2983–2996, 2010
Human Y‐chromosome short tandem repeats: A tale of acculturation and migrations as mechanisms for the diffusion of agriculture in the Balkan Peninsula

Published: January 2010

AbstractSoutheastern Europe and, particularly, the Balkan Peninsula are especially useful when studying the mechanisms responsible for generating the current distribution of Paleolithic and Neolithic genetic signals observed throughout Europe. In this study, 404 individuals from Montenegro and 179 individuals from Serbia were typed for 17 Y‐STR loci and compared across 9 Y‐STR loci to geographically targeted previously published collections to ascertain the phylogenetic relationships of populations within the Balkan Peninsula and beyond. We aim to provide information on whether groups in the region represent an amalgamation of Paleolithic and Neolithic genetic substrata, or whether acculturation has played a critical role in the spread of agriculture. We have found genetic markers of Middle Eastern, south Asian and European descent in the area, however, admixture analyses indicate that over 80% of the Balkan gene pool is of European descent. Altogether, our data support the view that the diffusion of agriculture into the Balkan region was mostly a cultural phenomenon although some genetic infiltration from Africa, the Levant, the Caucasus, and the Near East has occurred.

“Life history space”: A multivariate analysis of life history variation in extant and extinct Malagasy lemurs
Authors: Catlett Kierstin K. , Schwartz Gary T. , Godfrey Laurie R. , Jungers William L. 
Published: January 2010

AbstractStudies of primate life history variation are constrained by the fact that all large‐bodied extant primates are haplorhines. However, large‐bodied strepsirrhines recently existed. If we can extract life history information from their skeletons, these species can contribute to our understanding of primate life history variation. This is particularly important in light of new critiques of the classic “fast‐slow continuum” as a descriptor of variation in life history profiles across mammals in general. We use established dental histological methods to estimate gestation length and age at weaning for five extinct lemur species. On the basis of these estimates, we reconstruct minimum interbirth intervals and maximum reproductive rates. We utilize principal components analysis to create a multivariate “life history space” that captures the relationships among reproductive parameters and brain and body size in extinct and extant lemurs. Our data show that, whereas large‐bodied extinct lemurs can be described as “slow” in some fashion, they also varied greatly in their life history profiles. Those with relatively large brains also weaned their offspring late and had long interbirth intervals. These were not the largest of extinct lemurs. Thus, we distinguish size‐related life history variation from variation that linked more strongly to ecological factors. Because all lemur species larger than 10 kg, regardless of life history profile, succumbed to extinction after humans arrived in Madagascar, we argue that large body size increased the probability of extinction independently of reproductive rate. We also provide some evidence that, among lemurs, brain size predicts reproductive rate better than body size. Am J Phys Anthropol, 2010. © 2010 Wiley‐Liss, Inc.
Biocultural interpretations of trauma in two prehistoric Pacific Island populations from Papua New Guinea and the Solomon Islands
Authors: Scott Rachel M. , Buckley Hallie R. 
Published: January 2010

AbstractTwo Pacific Island skeletal samples originating from the inland site of Nebira, Papua New Guinea (1230–1650) and a coastal site on the small island of Taumako, Solomon Islands (1530–1698) were examined for evidence of skeletal trauma using a biocultural approach. The types of trauma identified were cranial trauma, postcranial fractures, and piercing and sharp force trauma. Both samples exhibit trauma (Nebira,n= 9/28, 32.1%; Taumako,n= 17/133, 12.8%). Postcranial fractures are significantly higher in males from Nebira (Fisher ExactPvalue = 0.025). The prevalence of cranial trauma (n= 6/28, 21.4%) is significantly higher in Nebira individuals (Fisher ExactPvalue = 0.007). There is no conclusive evidence of piercing trauma at Nebira unlike Taumako, which has four individuals with evidence of piercing or sharp force trauma. Both samples show evidence of interpersonal violence and warfare. The results suggest the environment may have contributed to the pattern of trauma at these sites. These patterns are discussed within their cultural and environmental contexts. Am J Phys Anthropol 142:509–518, 2010. © 2010 Wiley‐Liss, Inc.
