Published: June 2024

The forty-five genotypes of groundnut were evaluated at Field Experimentation Centre of the Department of Genetics and Plant Breeding, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.) during kharif, seasons of 2021-22 and 2022-23 in four artificially created environments by four different dates of sowing considered as E-I, E-II, E-III & E-IV. The present experiment was carried out in Randomized Block Design with three replications and involved recording observations on 17 yield and its contributing characters. Identifying stable-performing genotypes in the changing environmental scenario is of paramount importance in modern breeding materials. Crop improvement programme mostly depend on the identification of superior and stable genotypes. Mean sum of squares due to environment were found to be substantially distinct for all the traits and the mean sum of square due to genotype were found to be significant for all the characters. The regression coefficients (bi) of the genotypes ranged from -3.40 to 2.52 and the deviation from regression (S2di) ranged from -1.01 to 1.56. Stability parameters of various traits revealed that GJG-18, RG-574 and RG-559-3 pod yield per plant and RS-1 oil content showed high mean performance and regression coefficient close to unity and non-significant deviation from regression stable under overall environments. Thus indicating the importance of non-linear components in determining interaction of the genotypes with environments in the present study according to the Eberhart and Russell (1966) model.

Authors: Kann Laura , Kinchen Steve , Modzelski Bill , Sullivan Madeline , Carr Dana , Zaza Stephanie , Graffunder Corinne , Cetron Marty 
Published: June 2012

ABSTRACTObjective: This report provides an overview and assessment of the School Dismissal Monitoring System (SDMS) that was developed by the Centers for Disease Control and Prevention (CDC) and the US Department of Education (ED) to monitor influenza-like illness (ILI)-related school dismissals during the 2009-2010 school year in the United States.Methods: SDMS was developed with considerable consultation with CDC's and ED's partners. Further, each state appointed a single school dismissal monitoring contact, even if that state also had its own school-dismissal monitoring system in place. The SDMS received data from three sources: (1) direct reports submitted through CDC's Web site, (2) state monitoring systems, and (3) media scans and online searches. All cases identified through any of the three data sources were verified.Results: Between August 3, 2009, and December 18, 2009, a total of 812 dismissal events (ie, a single school dismissal or dismissal of all schools in a district) were reported in the United States. These dismissal events had an impact on 1947 schools, approximately 623 616 students, and 40 521 teachers.Conclusions: The SDMS yielded real-time, national summary data that were used widely throughout the US government for situational awareness to assess the impact of CDC guidance and community mitigation efforts and to inform the development of guidance, resources, and tools for schools.(Disaster Med Public Health Preparedness. 2012;6:104-112)
Prevention of Novel Influenza Infection in Newborns in Hospital Settings: Considerations and Strategies During the 2009 H1N1 Pandemic
Authors: Zapata Lauren B. , Kendrick Juliette S. , Jamieson Denise J. , MacFarlane Kitty , Shealy Katherine , Barfield Wanda D. 
Published: June 2012

ABSTRACTDuring the 2009 influenza A (H1N1) pandemic, many pregnant women experienced severe illness and some gave birth while ill with suspected or confirmed pandemic (H1N1) 2009 influenza. Because of concerns about possible transmission of this novel virus to immunologically naïve newborns, and the absence of definitive studies regarding this risk, the Centers for Disease Control and Prevention (CDC) reviewed relevant literature to understand the potential burden of disease and routes of transmission affecting newborns. This report describes the issues considered during the 2009 H1N1 pandemic as CDC developed guidance to protect newborns in hospital settings. Also presented is a framework of protection efforts to prevent novel influenza infection in fetuses/newborns before birth and in hospital settings. Although developed specifically for the pandemic, the framework may be useful during future novel influenza outbreaks.(Disaster Med Public Health Preparedness. 2012;6:97-103)
Increasing Out-of-Hospital Regional Surge Capacity for H1N1 2009 Influenza A Through Existing Community Pediatrician Offices: A Qualitative Description of Quality Improvement Strategies
Authors: Cruz Andrea T. , Tittle Kay O. , Smith Elizabeth R. , Sirbaugh Paul E. 
Published: June 2012

ABSTRACTObjective: To describe initiatives undertaken by a network of community pediatricians to increase a city's surge capacity for patients presenting with influenza-like illnesses during the 2009 H1N1 influenza A pandemic.Methods: This was a descriptive quality improvement project detailing the measures employed by a network of private practice community pediatricians in Houston, Texas, caring for both insured and uninsured children.Results: Four categories of interventions were used: enhanced communication, increasing community pediatrician presence, vaccine distribution, and targeted viral diagnosis and antiviral utilization. Promoting communication between clinicians, families, and an affiliated local tertiary care children's hospital allowed for the efficient coordination of resources as well as a unified and consistent message. Increasing access of families to their primary medical home by employing additional clinicians, extending office hours, and locating additional space served to decrease the number of children with low-acuity illness seen in the local emergency centers. Vaccine distribution was enhanced by effective communication between clinicians and families. Finally, targeted antiviral testing and adherence to national recommendations on antiviral utilization enabled judicious utilization of a limited supply of antiviral medications.Conclusions: Effective communication and improved access to health care enabled children within the network with influenza-like illnesses to continue to be cared for in their medical home. The measures used in response to novel influenza virus outbreaks can be adapted for other situations requiring increased community surge capacity.(Disaster Med Public Health Preparedness 2012;6:113-116)

Published: June 2012

ABSTRACTObjective: The novel H1N1 influenza pandemic renewed the concern that during a severe pandemic illness, critical care and mechanical ventilation resources will be inadequate to meet the needs of patients. Several published protocols address the need to triage patients for access to ventilator resources. However, to our knowledge, none of these has addressed the pediatric populations.Methods: We used a systematic review of the pediatric critical care literature to evaluate pediatric critical care prognosis and multisystem organ failure scoring systems. We used multiple search engines, including MEDLINE and EMBASE, using a search for terms and key words including including multiple organ failure, multiple organ dysfunction, PELOD, PRISM III, pediatric risk of mortality score, pediatric logistic organ dysfunction, pediatric index of mortality pediatric multiple organ dysfunction score, “child+multiple organ failure + scoring system. ” Searches were conducted in the period January 2010-February 2010.Results: Of the 69 papers reviewed, 22 were used. Five independently derived scoring systems were evaluated for use in a respiratory pandemic ventilator triage protocol. The Pediatric Logistic Organ Dysfunction (PELOD) scoring system was the most appropriate for use in such a triage protocol.Conclusions: We present a pediatric-specific ventilator triage protocol using the PELOD scoring system to complement the NY State adult triage protocol. Further evaluation of pediatric scoring systems is imperative to ensure appropriate triage of pediatric patients.(Disaster Med Public Health Preparedness. 2012;6:131–137)
Citizen Preparedness for Disasters: Are Current Assumptions Valid?
Authors: Uscher-Pines Lori , Chandra Anita , Acosta Joie , Kellermann Arthur 
Published: June 2012

ABSTRACTUS government programs and communications regarding citizen preparedness for disasters rest on several untested, and therefore unverified, assumptions. We explore the assumptions related to citizen preparedness promotion and argue that in spite of extensive messaging about the importance of citizen preparedness and countless household surveys purporting to track the preparedness activities of individuals and households, the role individual Americans are being asked to play is largely based on conventional wisdom. Recommendations for conceptualizing and measuring citizen preparedness are discussed.(Disaster Med Public Health Preparedness. 2012;6:170–173)

Published: June 2012

ABSTRACTObjective: The objective is to describe by geographic proximity the extent to which the US pediatric population (aged 0-17 years) has access to pediatric and other specialized critical care facilities, and to highlight regional differences in population and critical resource distribution for preparedness planning and utilization during a mass public health disaster.Methods: The analysis focused on pediatric hospitals and pediatric and general medical/surgical hospitals with specialized pediatric critical care capabilities, including pediatric intensive care units (PICU), pediatric cardiac ICUs (PCICU), level I and II trauma and pediatric trauma centers, and general and pediatric burn centers. The proximity analysis uses a geographic information system overlay function: spatial buffers or zones of a defined radius are superimposed on a dasymetric map of the pediatric population. By comparing the population living within the zones to the total population, the proportion of children with access to each type of specialized unit can be estimated. The project was conducted in three steps: preparation of the geospatial layer of the pediatric population using dasymetric mapping methods; preparation of the geospatial layer for each resource zone including the identification, verification, and location of hospital facilities with the target resources; and proximity analysis of the pediatric population within these zones.Results: Nationally, 63.7% of the pediatric population lives within 50 miles of a pediatric hospital; 81.5% lives within 50 miles of a hospital with a PICU; 76.1% lives within 50 miles of a hospital with a PCICU; 80.2% lives within 50 miles of a level I or II trauma center; and 70.8% lives within 50 miles of a burn center. However, state-specific proportions vary from less than 10% to virtually 100%. Restricting the burn and trauma centers to pediatric units only decreases the national proportion to 26.3% for pediatric burn centers and 53.1% for pediatric trauma centers.Conclusions: This geospatial analysis describes the current state of pediatric critical care hospital resources and provides a visual and analytic overview of existing gaps in local pediatric hospital coverage. It also highlights the use of dasymetric mapping as a tool for public health preparedness planning.(Disaster Med Public Health Preparedness. 2012;6:117–125)
Survey of Emergency Management Professionals to Assess Ideal Characteristics of a Photographic-Based Family Reunification Tool
Authors: Chung Sarita , Monteiro Stephen , Ziniel Sonja I. , Kalish Leslie A. , Klaman Paula , Shannon Michael 
Published: June 2012

ABSTRACTObjective: A reunification tool that captures images of children at the time of the disaster would enable parents to locate their missing children, particularly if the children are unable to communicate their identity. This study assessed the ideal features and parameters of a photographic-based reunification tool.Methods: A convenience sample of federal, state, and hospital-based emergency management professionals were surveyed to elicit their preferences regarding an image-based reunification algorithm, to assess the parents' level of difficulty in viewing images with facial trauma, and to determine the minimum percentage of successful reunifications needed to justify adoption of a reunification tool.Results: Of 322 emergency management professionals surveyed, 129 (40%) responded. Only 18% favored a photographic-based tool that would display images in which only the categories of age, gender, and facial features (eye, hair, and skin color) would exactly match the parent's description of the child. However, 72% preferred a broader, less-rigid system in which the images displayed would match all or most features in the parents’ description of the missing child, allowing parents to view more of the image database. Most (85%) preferred a tool showing unedited images of living children, allowing parents to view facial trauma. However, more respondents reported that parents would find viewing unedited images with facial trauma somewhat or very difficult emotionally compared with edited images for both living (77% vs 20%, P <. 001) and deceased children (91% vs 70%, P <. 001.) In a disaster involving 1000 children, a tool that reunites a minimum of 10% of families would be adopted by over 50% of the participants. Participants were willing to accept a lower percentage of reunifications in a disaster involving 1000 children compared with disasters involving 10 (P <. 001) or 100 children. (P <. 001).Conclusions: Emergency management professionals identified desirable characteristics of a photographic-based reunification tool, including an algorithm displaying unedited photographs of missing children that loosely matches the parents' description, acknowledging the parents' emotional difficulty in viewing photographs with facial trauma. Participants were also willing to accept a lower percentage of successful reunifications as the scale of the disaster size increased.(Disaster Med Public Health Preparedness. 2012;6:156–162)

Children's Implanted False Memories and Additional Script Knowledge
Authors: Otgaar Henry , Smeets Tom , Peters Maarten 
Published: June 2012

SummaryThe present study examined whether repeatedly providing additional script knowledge of an event would boost the development of children's implanted false memories. Seventy‐two 7‐ to 9‐year‐old children listened to a true narrative about their first day at school and a false narrative describing that they went to a burns centre when they were four years old. Children were randomly allocated to one of three groups: one group without additional script knowledge and two groups that received a video about the two events to promote additional event‐related script knowledge of which one group had to view the video repeatedly (i.e. once a day). Across two interviews, children were encouraged to tell everything they remembered about the events. Results showed that at the second interview, children who were presented with the additional script knowledge were more likely to develop a false memory than the children who did not receive additional script knowledge.

Adaptive iterative learning control of discrete‐time varying systems with unknown control direction
Authors: Yan Weili , Sun Mingxuan 
Published: June 2012

SUMMARYWithout using Nussbaum gain, a novel method is presented to solve the unknown control direction problem for discrete‐time systems. The underlying idea is to fully exploit the convergence property of parameter estimates in well‐known adaptive algorithms. By incorporating two modifications into the control and the parameter update laws, respectively, we present an adaptive iterative learning control scheme for discrete‐time varying systems without the prior knowledge of the sign of control gain. It is shown that the proposed adaptive iterative learning control can achieve perfect tracking over the finite time interval while all the closed‐loop signals remain bounded. An illustrative example is presented to verify effectiveness of the proposed scheme. Copyright © 2012 John Wiley & Sons, Ltd.
Emission Color Trajectory and White Electroluminescence Through Supramolecular Control of Energy Transfer and Exciplex Formation in Binary Blends of Conjugated Polyrotaxanes
Authors: Brovelli Sergio , Sforazzini Giuseppe , Serri Michele , Winroth Gustaf , Suzuki Kosuke , Meinardi Francesco , Anderson Harry L. , Cacialli Franco 
Published: June 2012

AbstractWhite electroluminescence and fine‐tuning of the emission color from binary blends of a blue‐emitting polymer and a green/yellow‐emitting threaded molecular wire consisting of a conjugated polymer supramolecularly encapsulated by functionalized cyclodextrins are demonstrated. Encapsulation controls the minimum intermolecular distance on the nanoscale, resulting in suppressed energy‐transfer between the blend constituents and reduced formation of interchain charge‐transfer complexes. The use of a green‐emitting polyrotaxane significantly improves the electrical properties with respect to blends of a blue electroluminescent polyrotaxane and leads to a significant reduction in the turn‐on voltage required for achieving white electroluminescence (VON = 3 V), with only 20% by weight of the encapsulated material.
Rapid Hydrogenation of Aromatic Nitro Compounds in Supercritical Carbon Dioxide: Mechanistic Implications via Experimental and Theoretical Investigations
Authors: Chatterjee Maya , Chatterjee Abhijit , Kawanami Hajime , Ishizaka Takayuki , Suzuki Toshishige , Suzuki Akira 
Published: June 2012

AbstractAn exceptionally rapid hydrogenation of nitrobenzene to aniline [TOF=252,000 h−1] over palladium containing MCM‐41 (Pd/MCM‐41) with excellent yield of >99% can be achieved in supercritical carbon dioxide at 50 °C and a hydrogen pressure of 2.5 MPa. It has been observed that this promising method preferred a single phase between liquid substrate and carbon dioxide‐hydrogen system. The ascendancy of the supercritical carbon dioxide medium is established in comparison with the conventional organic solvent and solvent‐less conditions. Changes in the reaction parameters such as carbon dioxide and hydrogen pressure, temperature and the reaction time do not affect the selectivity. A combined experimental and theoretical study has elucidated the mechanism under the studied reaction condition because experimental observations revealed a direct conversion of nitrobenzene to aniline. However, density functional theory (DFT) calculation shows that the direct conversion is energetically unfavourable; hence, a stepwise mechanism has been proposed. Theoretical predictions and experimental observations suggested that the rate‐limiting step of nitrobenzene conversion is different from that of the liquid phase hydrogenation. This catalytic process can also be successfully extended to the hydrogenation of other aromatic nitro compounds with different substituents. Easy separation of the liquid product from catalyst and the use of an environmentally friendly solvent make this procedure a viable and an attractive green chemical process.

Authors: Zhao Qian‐Yi , Huang Long , Wei Yin , Shi Min 
Published: June 2012

AbstractThe first example of a β‐isocupreidine (β‐ICD)‐catalyzed highly enantioselective [2+2] annulation of allenoates with trifluoromethyl ketones has been disclosed, allowing the synthesis of optically active 2‐alkyleneoxetanes in moderate to good yields along with good to high enantioselectivities and high diastereoselectivities. Further transformations of the cycloadducts have been also disclosed to afford biologically interesting 6‐trifluoromethyl‐5,6‐dihydropyran‐2‐ones and trifluoromethyl β‐keto acids in good yields.
Technical note: The use of geographical information systems software for the spatial analysis of bone microstructure
Authors: Rose David C. , Agnew Amanda M. , Gocha Timothy P. , Stout Sam D. , Field Julie S. 
Published: June 2012

AbstractGeographic information systems (GIS) software is typically used for analyzing geographically distributed data, allowing users to annotate points or areas on a map and attach data for spatial analyses. While traditional GIS‐based research involves geo‐referenced data (points tied to geographic locations), the use of this technology has other constructive applications for physical anthropologists. The use of GIS software for the study of bone histology offers a novel opportunity to analyze the distribution of bone nano‐ and microstructures, relative to macrostructure and in comparison to other variables of interest, such as biomechanical loading history. This approach allows for the examination of characteristics of single histological features while considering their role at the macroscopic level. Such research has immediate promise in examining the load history of bone by surveying the functional relationship between collagen fiber orientation (CFO) and strain mode. The diversity of GIS applications that may be utilized in bone histology research is just beginning to be explored. The goal of this study is to introduce a reliable methodology for such investigation and our objective is to quantify the heterogeneity of bone microstructure over an entire cross‐section of bone using ArcGIS v 9.3 (ESRI). This was accomplished by identifying the distribution of remodeling units in a human metatarsal relative to bending axes. One biomechanical hypothesis suggests that CFO, manifested by patterns of birefringence, is indicative of mode of strain during formation. This study demonstrates that GIS can be used to investigate, describe, and compare such patterns through histological mapping. Am J Phys Anthropol, 2012. © 2012 Wiley Periodicals, Inc.
