It's Better to Know! Learn the Signs. Act Early. Photo Novella
It’s Better to Know! Learn the Signs. Act Early. Learning About Developmental Milestones All of us want our children to be happy and healthy. We want what is best for them. This story is about my family as we learn that “It’s Better To Know” about developmental milestones. Developmental milestones are things most children can do by a certain age. Children reach milestones in how they play, learn, speak, and act. Milestones offer important clues about a child’s development. The developmental milestones you will learn about in this fotonovela will give you a general idea of what to expect as your child grows. Not reaching these milestones, or reaching them much later than other children, could be a sign of a developmental delay. Trust your instincts. If you have concerns about your child’s development, the best thing to do is talk with your doctor. It’s Better To Know! was produced by the Organization for Autism Research with funding provided by the Department of Health and Human Services, Centers for Disease Control and Prevention. www.cdc.gov/actearly iii He’s fine. He’s more interested in Hi Carlitos! his cow! C-a-r-l-i-t-o-s. He doesn’t always look at us when we call his name. I wonder why. Have you talked to How’s my baby boy the doctor about doing? that? He’s okay, mom, but he doesn’t always look up when No, why, should I? we call him. Remember the last time we took him for a well- baby check-up and 9-month developmental screening?

Secondary Organic Aerosol from Chlorine-Initiated Oxidation of Isoprene Dongyu S
Secondary organic aerosol from chlorine-initiated oxidation of isoprene Dongyu S. Wang and Lea Hildebrandt Ruiz McKetta Department of Chemical Engineering, The University of Texas at Austin, Austin, TX 78756, USA 5 Correspondence to: Lea Hildebrandt Ruiz ([email protected]) Abstract. Recent studies have found concentrations of reactive chlorine species to be higher than expected, suggesting that atmospheric chlorine chemistry is more extensive than previously thought. Chlorine radicals can interact with HOx radicals and nitrogen oxides (NOx) to alter the oxidative capacity of the atmosphere. They are known to rapidly oxidize a wide range of volatile organic compounds (VOC) found in the atmosphere, yet little is known about secondary organic aerosol (SOA) 10 formation from chlorine-initiated photo-oxidation and its atmospheric implications. Environmental chamber experiments were carried out under low-NOx conditions with isoprene and chlorine as primary VOC and oxidant sources. Upon complete isoprene consumption, observed SOA yields ranged from 8 to 36 %, decreasing with extended photo-oxidation and SOA aging. Formation of particulate organochloride was observed. A High-Resolution Time-of-Flight Chemical Ionization Mass Spectrometer was used to determine the molecular composition of gas-phase species using iodide-water and hydronium-water 15 cluster ionization. Multi-generational chemistry was observed, including ions consistent with hydroperoxides, chloroalkyl hydroperoxides, isoprene-derived epoxydiol (IEPOX) and hypochlorous acid (HOCl), evident of secondary OH production and resulting chemistry from Cl-initiated reactions. This is the first reported study of SOA formation from chlorine-initiated oxidation of isoprene. Results suggest that tropospheric chlorine chemistry could contribute significantly to organic aerosol loading. -
Health Effects Support Document for Hexachlorobutadiene Health Effects Support Document for Hexachlorobutadiene
Health Effects Support Document for Hexachlorobutadiene Health Effects Support Document for Hexachlorobutadiene U.S. Environmental Protection Agency Office of Water (4304T) Health and Ecological Criteria Division Washington, DC 20460 www.epa.gov/safewater/ EPA 822-R-03-002 February 2003 Printed on Recycled Paper FOREWORD The Safe Drinking Water Act (SDWA), as amended in 1996, requires the Administrator of the Environmental Protection Agency (EPA) to establish a list of contaminants to aid the agency in regulatory priority setting for the drinking water program. In addition, SDWA requires EPA to make regulatory determinations for no fewer than five contaminants by August 2001. The criteria used to determine whether or not to regulate a chemical on the CCL are the following: The contaminant may have an adverse effect on the health of persons. The contaminant is known to occur or there is a substantial likelihood that the contaminant will occur in public water systems with a frequency and at levels of public health concern. In the sole judgment of the administrator, regulation of such contaminant presents a meaningful opportunity for health risk reduction for persons served by public water systems. The Agency’s findings for the three criteria are used in making a determination to regulate a contaminant. The Agency may determine that there is no need for regulation when a contaminant fails to meet one of the criteria. This document provides the health effects basis for the regulatory determination for hexachlorobutadiene. In arriving at the regulatory determination, data on toxicokinetics, human exposure, acute and chronic toxicity to animals and humans, epidemiology, and mechanisms of toxicity were evaluated. -

Bath experiments demonstrated that the Pd/Fe bimetallic particles could effectively remove AOX. It indicated several factors, such as Pd loading, the amount of Pd/Fe used, initial activated sludge pH, and reaction time, which could affect the removal effect. The results showed that increasing the Pd content in Pd/Fe particles, from 0.01 to 0.05 wt %, significantly increased the removal efficiency of AOX in activated sludge. The Pd/Fe particles had a much higher removal efficiency of AOX in the activated sludge than bare Fe particles. A slightly acidic condition with a Pd content of 0.05% and 10 g/L of Pd/Fe was beneficial to the process of removing AOX in activated sludge. In detail, the removal efficiency of AOX in the activated sludge could reach 50.7% after 15 days of reaction with 10 g/L of Pd/Fe (Pd loading 0.05 wt %) and at an initial pH of 6.0 during the experiments. -

Molecular Characterization of Soil Bacterial Community in a Perhumid, Low Mountain Forest
Microbes Environ. Vol. 26, No. 4, 325–331, 2011 http://wwwsoc.nii.ac.jp/jsme2/ doi:10.1264/jsme2.ME11114 Molecular Characterization of Soil Bacterial Community in a Perhumid, Low Mountain Forest YU-TE LIN1, WILLIAM B. WHITMAN2, DAVID C. COLEMAN3, and CHIH-YU CHIU1* 1Biodiversity Research Center, Academia Sinica, Nankang, Taipei 11529, Taiwan; 2Department of Microbiology, University of Georgia, Athens, GA, 30602–2605, USA; and 3Odum School of Ecology, University of Georgia, Athens, GA, 30602–2602, USA (Received February 10, 2011—Accepted June 3, 2011—Published online July 5, 2011) Forest disturbance often results in changes in soil properties and microbial communities. In the present study, we characterized a soil bacterial community subjected to disturbance using 16S rRNA gene clone libraries. The community was from a disturbed broad-leaved, low mountain forest ecosystem at Huoshaoliao (HSL) located in northern Taiwan. This locality receives more than 4,000 mm annual precipitation, one of the highest precipitations in Taiwan. Based on the Shannon diversity index, Chao1 estimator, richness and rarefaction curve analysis, the bacterial community in HSL forest soils was more diverse than those previously investigated in natural and disturbed forest soils with colder or less humid weather conditions. Analysis of molecular variance also revealed that the bacterial community in disturbed soils significantly differed from natural forest soils. Most of the abundant operational taxonomic units (OTUs) in the disturbed soil community at HSL were less abundant or absent in other soils. The disturbances influenced the composition of bacterial communities in natural and disturbed forests and increased the diversity of the disturbed forest soil community. -

FALL 2020 ACADEMIC REGALIA Though our ceremonies look different this year, regalia traditions are beloved, timeless and span decades — and pandemics. Our graduates have earned the right to don regalia and adornments for the rest of their lives that reflect the dedication they have shown to their field and the love they have for their alma mater. The custom of recognizing the accomplishments of scholars through distinctive dress, color and ceremony began in the Middle Ages and has been adopted by various academic institutions throughout the world. American academic regalia developed from the English traditions that originated at the University of Cambridge and the University of Oxford and has been in continuous use in this country since Colonial times. Institutions of higher learning in the United States have adopted a system for identifying different academic degrees by use of specific gowns, hoods and colors. The baccalaureate (bachelor’s) gown is identified by long pointed sleeves. The master’s gown has a very long sleeve, closed at the bottom, and the wearer’s arm is placed through an opening in the front of the sleeve. Master’s gowns also are distinguished by green panels down the front of the gown. Doctoral gowns are distinguished by velvet panels around the neck and down the front of the gown. Three horizontal velvet bars on each sleeve also may mark the doctorate. The colorful hoods worn by master’s and doctoral graduates represent the specific degree earned and the degree-granting institution. Hoods for UNT are distinguished by a kelly-green-and-white chevron lining. -

Rhodoplanes Gen. Nov., a New Genus of Phototrophic Including
INTERNATIONALJOURNAL OF SYSTEMATICBACTERIOLOGY, Oct. 1994, p. 665-673 Vol. 44, No. 4 0020-7713/94/$04.00+0 Copyright 0 1994, International Union of Microbiologicai Societies Rhodoplanes gen. nov., a New Genus of Phototrophic Bacteria Including Rhodopseudomonas rosea as Rhodoplanes roseus comb. nov. and Rhodoplanes elegans sp. nov. AKIRA HIMISHI* AND YOKO UEDA Laboratory of Environmental Biotechnology, Konishi Co., Yokokawa, Sumida-ku, Tokyo 130, Japan Two new strains (AS130 and AS140) of phototrophic purple nonsulfur bacteria isolated from activated sludge were characterized and compared with Rhodopseudomoms rosea and some other species of the genus Rhodopseudomoms. The new isolates produced pink photosynthetic cultures, had rod-shaped cells that divided by budding, and formed intracytoplasmic membranes of the lamellar type together with bacteriochlorophyll a and carotenoids of the normal spirilloxanthin series. They were also characterized by their capacity for complete denitrification and their production of both ubiquinone-10 and rhodoquinone-10 as major quinones. The isolates were phenotypically most similar to R. rosea but exhibited low levels of genomic DNA hybridization to this species and to all other Rhodopseudomonas species compared. Phylogenetic analyses on the basis of PCR-amplified 16s rRNA gene sequences showed that our isolates and R. rosea formed a cluster distinct from other members of the genus Rhodopseudomonas. The phenotypic, genotypic, and phylogenetic data show that the new isolates and R. rosea should be placed in a new single genus rather than included in the genus Rhodopseudomonas. Thus, we propose to transfer R. rosea to a new genus, Rhodoplanes, as Rhodoplanes roseus gen. nov., comb. nov. (type species) and to designate strains AS130 and AS140 a new species, Rhodoplanes elegans sp.
