An examination of the type material of Rissoina inaijori Dall, 1927, confirmed that Ponder (1983) was correct in allocating the species to the familyj Epitoniidae. It is here redescribed and a lectotype is designated. Because of the similarity in shell characters and the overlap in geographic range, we consider R. mayori and Opalia pumilio (Mörch, 1875) to be synonyms.

Objective: The purpose of this study was to perform an in situ assessment of office seating habits that influence chair testing and design. Background: Many chair testing parameters were derived decades ago when the average weight of people within the United States was dramatically lower and the office work tasks less computer based. Method: For the study, 51 participants were randomly selected from Brazos Valley, Texas, businesses to participate in 8-hr assessments of office seating habits. Overall results were compared with current chair testing and design assumptions. Data were collected through written survey and through data logging of seat and back contact pressure and duration with the use of the X-SENSOR™ pressure mapping device and software. Additionally, 1 day per participant of caster roll distance was recorded with the use of a caster mounted digital encoder. Participants were grouped by body mass index (BMI) and weight (BMI <35 and weight <102 kg or BMI >35 and weight >102 kg). Results: It was determined that a significant difference did exist between the groups in mean seat time per shift (p <.001), back cycles per shift (p <.002), seat cycles per shift (p <.01), and caster distance rolled per shift (p <.001). Conclusion: Several key parameters and assumptions of current chair test methods and design specifications may no longer be valid for the upper quartile of weight range of the current U.S. population. Application: The data collected in this study will enable engineers to determine whether revision of design standards for testing office seating for both normal weight and extremely obese workers is indicated. © 2011, Human Factors and Ergonomics Society.

Information systems and intelligent smart grid data analytics will have a critical role in managing the massive amount of data becoming available in power system substations. Digital protective relays are multi-functional intelligent electronic devices based on microprocessors, which are being installed in substations throughout the power grid. New digital relays are replacing old-fashioned electro-mechanical or solid-state relays, and besides their protective function, they are coming equipped with monitoring capabilities. These monitoring capabilities are creating potential for better observability of power systems, redundancy in measurements, and improved decision-making process when operating the system. This article discusses the implementation requirements for a fully automated data analytics solution that provides data integration, fault analysis, and visualization based on the event data recorded by digital protective relays. © 2013, Springer Science+Business Media New York.

A subsample of 332. 0.06-hectare plots measured during 2001-2002 in Houston, TX, U.S., were relocated and measured in 2008 following Hurricane Ike. These 37 re-measured plots provide a unique opportunity to explore the effects of urbanization and hurricanes on the forest structure of coastal urban forests. Statistical analyses of growth, mortality, and in-growth were conducted using plot- and tree-level factors. In total, 305 trees were re-measured, of which 195 (63.9%) still remained on-site and 110 (36.1%) had been removed. Ninety-seven (3.1.8%) of these trees were determined to be removed due to urbanization and 13 trees (4.3%) were removed due to hurricane impacts. Results show an overall annual net loss in tree numbers and an increase in tree density during the analysis period. Average annual, mortality and in-growth rates were 3.9% and 5.3%, respectively. Growth rates were significantly influenced by land cover type, tree stem diameter, crown width, and percent dieback (P < 0.05). Overall, Hurricane Ike resulted in the removal of 4.3% of all trees measured, with removal occurring on six (16%) of the 37 re-measured plots. These initial findings could be used to understand changes in forest structure in coastal urban areas, improve estimates of carbon sequestration, and develop management goals. © 2011 International Society of Arboriculture.

The consumption of high-fat hamburger enriched with SFA and trans-fatty acids may increase risk factors for coronary vascular disease, whereas hamburger enriched with MUFA may have the opposite effect. Ten mildly hypercholesterolaemic men consumed five, 114g hamburger patties per week for two consecutive phases. Participants consumed high-SFA hamburger (MUFA:SFA=095; produced from pasture-fed cattle) for 5 weeks, consumed their habitual diets for 3 weeks and then consumed high-MUFA hamburger (MUFA:SFA=131; produced from grain-fed cattle) for 5 weeks. These MUFA:SFA ratios were typical of ranges observed for retail ground beef. Relative to habitual levels and levels during the high-MUFA phase, the high-SFA hamburger: increased plasma palmitic acid, palmitoleic acid and TAG (P<001); decreased HDL cholesterol (HDL-C) and LDL particle diameter percentile distributions (P<005); and had no effect on LDL cholesterol or plasma glucose (P>010). Plasma palmitoleic acid was positively correlated with TAG (r 090), VLDL cholesterol (r 073) and the LDL:HDL ratio (r 045), and was negatively correlated with plasma HDL-C (r 058), whereas plasma palmitic, stearic and oleic acids were negatively correlated with LDL particle diameter (all P005). Because plasma palmitoleic acid was derived from 9 desaturation of palmitic acid in liver, we conclude that alterations in hepatic stearoyl-CoA desaturase activity may have been responsible the variation in HDL-C and TAG caused by the high-SFA and high-MUFA hamburgers. © 2009 The Authors.

Differences in grain mould disease levels among different sorghum varieties grown in the same environment imply that host genes play a role in controlling disease severity. The fungi most often recovered from naturally infected sorghum grain, Fusarium thapsinum and Curvularia lunata, were used to inoculate a set of resistant and susceptible cultivars at anthesis in both field and glasshouse trials. In the field, 12 cultivars were inoculated with a mixture of F. thapsinum and C. lunata and, in the glasshouse, individual panicles from four selected cultivars were inoculated with spore suspensions of C. lunata, F. thapsinum, a mixture of the two or water to serve as a control. Based on grain mould severity ratings and germination tests on the seed from the field trial, Tx2911, Sureno, SC719-11E and SC650-11E displayed a high level of resistance to grain mould. To determine whether resistant and susceptible lines differed in response to the pathogens, PR-10 mRNA levels were measured using real-time reverse transcriptase-polymerase chain reaction. PR-10 is a protein with antifungal properties that has been associated with defence responses in sorghum and other plant species. In field tests, most, but not all, cultivars showed significant induction of normalized relative quantities of PR-10 after dual inoculation with spores of both C. lunata and F. thapsinum. Under glasshouse-controlled conditions, glumes of inoculated plants showed the clear induction of PR-10 mRNA, and the response was greater in resistant (Tx2911 and Sureno) than in susceptible (RTx430 and SC170-6-17) cultivars. Inoculation with spores from a single mould-inducing pathogen generally induced greater responses than when spores were combined. For RTx430, SC170-6-17 and Sureno, the response to C. lunata was greater, whereas Tx2911 showed a stronger response to F. thapsinum. The results indicate that the induction of PR-10 in sorghum glumes may be a factor useful in breeding programmes designed to combine multiple factors for resistance. © 2009 Blackwell Publishing Ltd.

Background: During endoscopic sinus surgery (ESS), postoperative lateralization of the middle turbinate can lead to scarring and obstruction of key drainage pathways, including the osteomeatal complex. The technique of suturing the middle turbinate to the nasal septum to enhance exposure can be difficult and time consuming. This study presents the first clinical results using the Middle Turbinate Implant (MTI), a device composed of absorbable copolymer polylactide-co-glycolide and intended to medialize the middle turbinate during surgical procedures such as ESS. Methods: The trial included 22 implantations (21 successful implantations) on 14 subjects (6 unilateral and 8 bilateral implantations). The primary outcome measure was the position of the middle turbinate at 1, 2, and 4 weeks postoperatively. The extent of tissue reaction at the site of implantation was also evaluated. Results: At 1, 2, and 4 weeks postoperatively, 100% of the middle turbinates were held medially or in the neutral position with no significant synechiae present. At 1, 2, and 4 weeks postoperatively, there was either no (95%, 90%, and 95%) or mild (5%, 10%, and 5%) tissue reaction at the site of implantation. No complications were noted during implantation. Conclusion: The use of the bioresorbable MTI appears to be a safe and effective method of medializing the middle turbinate during ESS. © 2011 ARS-AAOA, LLC.

Environmental labs performing purge and trap GC/MS analysis of VOCs in soil, drinking water, wastewater, groundwater and sediment samples require a versatile and reliable automation platform to transfer samples to purge and trap GC/MS systems without sacrificing sample integrity or data quality. One instrument that meets the pragmatic operational needs of environmental testing labs and also fulfills U.S. EPA hardware and quality control requirements is the 4100 Soil/Water Sample Processor from O.I. Analytical, a Xylem brand. The sample processor automates the handling and processing of up to 100 soil and/or water samples in 40mL volatile organic analysis (VOA) vials for purge and trap analysis of VOCs in accordance with U.S. EPA methods. The digitally controlled linear drive rails and pneumatically actuated VOA Constrictor™ vial gripper combine to lift and transport 40mL VOA vials to and from the sampling station with high reliability. The parameters used to judge the effectiveness are the response factor, the relative standard deviation (RSD) and the R2 value.
