Gender‐Related In Vitro Metabolism of Hexaconazole and Its Enantiomers in Rats
Authors: Shen Zhigang , Liu Donghui , Wang Peng , Zhang Ping , Wang Xinru , Zhou Zhiqiang 
Published: September 2013

ABSTRACTIn the present study we investigated the enantioselective disappearance of hexaconazole in rat liver microsomes system prepared from both genders. High‐performance liquid chromatography (HPLC) was used for identification and quantification. The degradation of the (+)‐hexaconazole was faster than that of the (−)‐hexaconazole in racemic hexaconazole and single enantiomer incubation in both sexes. The degradation half‐life of the (+)‐hexaconazole or (−)‐hexaconazole was also gender‐related. The metabolism of (+)‐hexaconazole and (−)‐hexaconazole were faster in male rat hepatic microsomes than that in female, suggesting that at least one of the cytochrome P450s (CYP) in the male rat liver microsomes system responsible for hexaconazole metabolism was male‐specific or considerably more active. Kinetic assays showed that the intrinsic clearance in male rat liver microsomes was higher than that in female. All these results strongly suggest that sexual dimorphic metabolism of hexaconazole exists in rats. The inhibition experiments with CYP inhibitors showed that the inhibitory effect of inhibitors was enantioselective and affected by sex. The results suggest that the enantioselective metabolism of hexaconazole was determined by the amount of hepatic cytochrome P450 and the expression of individual isoforms of CYPs.

Introduction of an Isolation Chromophore into an “H”‐Shaped NLO Polymer: Enhanced NLO Effect, Optical Transparency, and Stability
Authors: Wu Wenbo , Ye Cheng , Qin Jingui , Li Zhen 
Published: September 2013

AbstractIn this study, a new polymer P1 embedded with “H”‐type chromophore moieties was designed and synthesized through Suzuki coupling copolymerization, in which the isolation chromophore was introduced to further improve its comprehensive performance. This polymer demonstrated good solubility and film‐forming ability. In comparison with normal ”H”‐shaped NLO polymers only containing one type of chromophore, nearly all the performance of P1 was improved. Its NLO coefficient was as high as 134 pm V−1, and its onset temperature for decay was up to 150 °C. Coupled with its improved optical transparency, all these properties made it a promising candidate for practical applications in photonic fields.
Resistance and capacitance of 4 × n cobweb network and two conjectures
Authors: Tan Zhi‐Zhong , Zhou Ling , Luo Da‐feng 
Published: September 2013

SummaryA classic problem in electric circuit theory studied by numerous authors over 160 years is the computation of the resistance between two nodes in a resistor network, yet some basic problem in m × n cobweb network is still not solved ideally. The equivalent resistance and capacitance of 4 × n cobweb network are investigated in this paper. We built a quaternion matrix equation and proposed the method of matrix transformations in terms of the network analysis. We proposed a brief equivalent resistance formula and find that the equivalent resistance is expressed by cos(kπ/9) in a series of strict calculation. Meanwhile, an equivalent resistance of infinite networks is gained. Using the inverse mapping relation between capacitance parameters and resistance parameters, the equivalent capacitance formula is also given for the 4 × n capacitance cobweb network. By analyzing and comparing the equivalent resistances of the 1 × n, 2 × n, 3 × n and 4 × n cobweb networks, two conjectures on the equivalent resistance and capacitance of the m × n cobweb network are proposed.

Thermal response characteristics of fire blanket materials
Authors: Takahashi Fumiaki , Abbott Amber , Murray Timothy M. , T'ien James S. , Olson Sandra L. 
Published: September 2013

SUMMARYThe thermal response characteristics of over 50 relatively thin (0.15–3.7 mm) fire blanket materials from four different fiber groups (aramid, fiberglass, amorphous silica, and pre‐oxidized carbon) and their composites have been investigated. A plain or coated fabric sample was subjected to a predominantly convective or radiant heat flux (up to 84 kW/m2) using a Meker burner and a cone heater, respectively. In addition to conventional thermal protective performance ratings for protective clothing, two transient thermal response times (for the fabric back‐side temperature to reach 300 °C and for the through‐the‐fabric heat flux to reach 13 kW/m2) and a steady‐state heat‐blocking efficiency (HBE) were introduced for both convective and radiant heat sources. For most woven fabrics, the HBE values were approximately 70 ± 10% for both convection and radiation and only mildly increased with the fabric thickness or the incident heat flux. Nonwoven (felt) fabrics with low thermal conductivity exhibited significantly better insulation (up to 87%) against convective heat. Highly reflective aluminized materials exhibited exceptionally high HBE values (up to 98%) for radiation, whereas carbon and charred aramid fabrics showed lower HBEs (down to 50%) because of efficient radiation absorption. A relatively thin fire blanket operating at high temperatures can efficiently block heat from a convective source by radiative emission (enhanced by its T4‐dependence and high surface emissivity) coupled with thermal insulation and from a radiant heat source by surface reflection while the aluminum surface layer remains.

A new standardized Palmer drought index for hydro‐meteorological use
Authors: Ma Mingwei , Ren Liliang , Yuan Fei , Jiang Shanhu , Liu Yi , Kong Hao , Gong Luyan 
Published: September 2013

AbstractAccepting the concept of standardization introduced by the standardized precipitation index, similar methodologies have been developed to construct some other standardized drought indices such as the standardized precipitation evapotranspiration index (SPEI). In this study, the authors provided deep insight into the SPEI and recognized potential deficiencies/limitations in relating to the climatic water balance it used. By coupling another well‐known Palmer drought severity index (PDSI), we proposed a new standardized Palmer drought index (SPDI) through a moisture departure probabilistic approach, which allows multi‐scalar calculation for accurate temporal and spatial comparison of the hydro‐meteorological conditions of different locations. Using datasets of monthly precipitation, temperature and soil available water capacity, the moisture deficit/surplus was calculated at multiple temporal scales, and a couple of techniques were adopted to adjust corresponding time series to a generalized extreme value distribution out of several candidates. Results of the historical records (1900–2012) for diverse climates by multiple indices showed that the SPDI was highly consistent and correlated with the SPEI and self‐calibrated PDSI at most analysed time scales. Furthermore, a simple experiment of hypothetical temperature and/or precipitation change scenarios also verified the effectiveness of this newly derived SPDI in response to climate change impacts. Being more robust and preferable in spatial consistency and comparability as well as combining the simplicity of calculation with sufficient accounting of the physical nature of water supply and demand relating to droughts, the SPDI is promising to serve as a competent reference and an alternative for drought assessment and monitoring.

Modelling hydrological connectivity of tropical floodplain wetlands via a combined natural and artificial stream network
Authors: Karim Fazlul , Kinsey‐Henderson Anne , Wallace Jim , Godfrey Paul , Arthington Angela H. , Pearson Richard G. 
Published: September 2013

AbstractThe ecological condition and biodiversity values of floodplain wetlands are highly dependent on the hydrological connectivity of wetlands to adjacent rivers. This paper describes a method for quantifying connectivity between floodplain wetlands and the main rivers in a wet tropical catchment of northern Australia. We used a one‐dimensional hydrodynamic model to simulate time‐varying water depths across the stream network (i.e. rivers, streams and man‐made drains). The timing and duration of connectivity of seven wetlands (four natural and three artificial) with the two main rivers in the catchment were then calculated for different hydrological conditions. Location and areal extent of the wetlands and the stream network were identified using high‐resolution laser altimetry, and these data formed key inputs to the hydrodynamic model. The model was calibrated using measured water depths and discharges across the floodplain. An algorithm was developed to identify contiguous water bodies at daily time steps, and this gave the temporal history of connection and disconnection between wetlands and the rivers. Simulation results show that connectivity of individual wetlands to both rivers varies from 26 to 365 days during an average hydrological condition. Location, especially proximity to a main river, and wetland type (natural stream or artificial drain) were identified as key factors influencing these levels of connectivity. Some natural wetlands maintain connection with the river for most or all of the year, whereas the connectivity of some artificial wetlands varies from 26 to 36 days according to their patterns of network connection to adjacent rivers – a result that has important implications for the accessibility of these types of wetland to aquatic biota. Using readily available river gauge data, we also show how connectivity modelling can be used to identify periods when connectivity has fallen below critical thresholds for fish movement. These connectivity patterns within the floodplain network are central to the setting of river flows that will meet environmental requirements for biota that use floodplain wetlands during their life history.

How much complexity is needed to simulate watershed streamflow and water quality? A test combining time series and hydrological models
Authors: Chien Huicheng , Mackay D. Scott 
Published: September 2013

AbstractModelled hydrologic processes are represented in a set of numerical equations; the complexity of which can be measured by the total number of variables needed. A single dominant hydrologic process could control the hydrologic response of a watershed, and so the identification of the corresponding dominant variable(s) would aid in identifying a parsimonious model and in collecting more reliable data. By accounting for both model complexity and serial correlation in the variables, a model is used to identify the dominant variables for representing watershed scale streamflow, sediment transport and phosphorus yields. Long‐term water quantity and quality data were used to show that rainfall and non‐linear soil water storage were the dominant variables for weekly streamflow, suspended sediment and particulate phosphorus. Model accuracy did not consistently improve when other statistically significant variables were included. The results suggest that improved model performance may not justify the added model complexity. As such, identification of dominant variables would be the priority for developing parsimonious hydrologic models, especially at watershed scales. Copyright © 2013 John Wiley & Sons, Ltd.
Training Family Therapists: Creating a Learning Experience
Authors: Colling Terry , Szymczak Len 
Published: September 2013

This article describes the structure of a Three Day Residential Workshop for experienced therapists. We were concerned that workshops for family therapists often failed to provide a sense of continuity and movement from one interview to the next. We also felt that workshops, through their process, imply an expectation of uniformity in style that may inhibit the creativity and spontaneity of the therapists.We therefore chose the Growth Model of family therapy as we experimented with a format that: (a) used sequential interviews which broke some well established rules of role‐playing, (b) utilized a team approach as a useful tool in furthering the learning experience, and (c) exposed the participants to a variety of therapy styles.In this article we seek to Illustrate those components of the workshop that proved successful and those areas which needed to be changed in order to make it a more effective learning experience. We conclude with specific recommendations regarding the structuring of such workshops.

Structural Problems in the Formation and Function of Blended Families
Authors: Preston G. 
Published: September 2013

AbstractThis paper outlines a structural family therapy analysis of the problems that occur in the formation and functioning of blended families. The difference between blended families and other types of family is discussed and an attempt is made to differentiate blended families from each other. Common structural problems in blended families are described with case study examples. Reference is made to the part that access and custody disputes play in the problems of the blended family and some suggestions are made regarding therapy with these families.
