Comparative morphology and identification key for females of nine Sarcophagidae species (Diptera) with forensic importance in Southern Brazil

ABSTRACTThe identification of female flesh flies was always considered a difficult task since morphological descriptions and keys for females are rare. Even in a forensic entomology framework, where females play a major role, female flesh flies are usually not identified. In order to fill this gap in Southern Brazil fauna we provide detailed descriptions and key for the female of nine species included in four genera: Microcerella halli (Engel), Oxysarcodexia paulistanensis (Mattos), Oxysarcodexia riograndensis (Lopes), Peckia (Euboettcheria) australis (Townsend), Peckia(Euboettcheria) florencioi (Prado and Fonseca), Peckia (Pattonella) intermutans (Walker), Peckia(Pattonella) resona (Lopes), Peckia (Sarcodexia) lambens (Wiedemann), and Sarcophaga(Bercaea) africa (Wiedemann). These species are distinguished mainly by genital characters as tergite 6 divided or undivided, presence of tergite 8, spermatheca morphology and vaginal plate shape.

Environmental Assessment: IA 12 in Mason City From S. Monroe Ave to S. Carolina Ave, Cerro Gordo County, Iowa, NHSX-122-1(14)--3H-17, 2013

DESCRIPTION OF PROPOSED ACTION This Environmental Assessment (EA) has been prepared in compliance with the requirements of the National Environmental Policy Act of 1969 (NEPA). This EA informs the public and interested agencies of the proposed action and alternatives to the proposed action in order to gather feedback on the improvements under consideration. Proposed Action The Iowa Department of Transportation (Iowa DOT) and the Federal Highway Administration (FHWA) are evaluating potential alternatives to improve IA 122 in the City of Mason City. IA 122/Business US 18 is a primary east-west travel route through the City that transitions from a 4- lane undivided roadway, to 2-lane one-way pairs, then back to a 4-lane undivided roadway (Figure 1-1). The Iowa DOT proposes to flatten the tight reverse curves on the east end of the project. The one-way pairs will be narrowed by eliminating on-street parking along the corridor to more clearly define travel lanes. This will serve to calm traffic flows and reduce crashes along the highway. Additionally, improvements to intersections as well as consolidating or removing access points to improve traffic operations are proposed within the project corridor. A new access road for the Mason City Fire Department on the west end of the project will allow emergency trucks better access to travel south and east. Study Area The primary area of investigation for the Project is generally bounded by IA 122 through Mason City, known locally as 5th and 6th Street Southwest from South Monroe Avenue to South Carolina Avenue. US 65, known locally as Federal Avenue, bisects the study area. At this intersection of US 65 and Iowa 122, the 5th and 6th Street SW changes to 5th and 6th St SE. For the purposes of this discussion, this area will be referred to collectively as the IA 122 corridor. The Study Area boundaries were established to allow the development of a wide range of alternatives that could address the purpose and need for the project. The Study Area is larger than the area proposed for construction activities for the Project. However, some impacts may extend beyond the Study Area; where this occurs, it will be noted and addressed in the Environmental Analysis Section (Section 5). Figure 1-1 outlines the Study Area of the proposed action.

An Assessment of Traffic Safety in Urban Deer Herd Management Zones in Iowa, 2010

Many states are striving to keep their deer population to a sustainable and controllable level while maximizing public safety. In Iowa, measures to control the deer population include annual deer hunts and special deer herd management plans in urban areas. While these plans may reduce the deer population, traffic safety in these areas has not been fully assessed. Using deer population data from the Iowa Department of Natural Resources and data on deer-vehicle crashes and deer carcass removals from the Iowa Department of Transportation, the authors examined the relationship between deer-vehicle collisions, deer density, and land use in three urban areas in Iowa that have deer management plans in place (Cedar Rapids, Dubuque, and Iowa City) over the period 2002 to 2007. First, a comparison of deer-vehicle crash counts and deer carcass removal counts was conducted at the county level. Further, the authors estimated econometric models to investigate the factors that influence the frequency and severity of deer-vehicle crashes in these zones. Overall, the number of deer carcasses removed on the primary roads in these counties was greater than the number of reported deervehicle crashes on those roads. These differences can be attributed to a number of reasons, including variability in data reporting and data collection practices. In addition, high rates of underreporting of crashes were found on major routes that carry high volumes of traffic. This study also showed that multiple factors affect deer-vehicle crashes and corresponding injury outcomes in urban management zones. The identified roadway and non-roadway factors could be useful for identifying locations on the transportation system that significantly impact deer species and safety and for determining appropriate countermeasures for mitigation. Efforts to reduce deer density adjacent to roads and developed land and to provide wider shoulders on undivided roads are recommended. Improving the consistency and accuracy of deer carcass and deer-vehicle collision data collection methods and practices is also desirable.

Mississippi Drive (Iowa 92) from Main Street to the Norbert F. Beckey Bridge in Muscatine, Iowa, STP-U-5330(614)—27-70, Muscatine County, 2015

The proposed action consists of upgrading Mississippi Drive (Iowa Highway 92) through downtown Muscatine, Iowa. The Mississippi Drive Corridor Project begins south of the Main Street/Grandview Avenue intersection, continuing to the East 2nd Street/Norbert F. Beckey Bridge intersection, which marks the end of the project. It passes through a mix of commercial, residential, Central Business District and industrial land uses. The total length of the project is approximately 1.6 miles, including 19 intersections (6 with traffic signals). Refer to the vicinity map on Figure 1. The current roadway is a 3- to 4-lane, urban facility with both divided and undivided medians. The roadway, ranging from 40 to 64 feet wide, is considered difficult to cross for pedestrians, especially for small children or elderly. The width of this roadway is being considered to be narrowed to improve the accessibility to the downtown from the Mississippi River riverfront area by pedestrians. This project also includes accommodations for bicycles and pedestrians and measures to reduce flooding on the roadway.

Development of the Des Moines Access Management Plan, 2004

According to Iowa crash records, almost 10% of all crashes in Iowa occur at commercial driveways. Most of these crashes occur on arterials within municipalities. In recent years, nearly a quarter of these crashes have occurred in the Des Moines metropolitan area. This makes the Des Moines metropolitan area a prime candidate for improved access management. Case study research in Iowa has shown that access management is an extremely effective highway safety tool—well-managed routes are, on average, 40% safer than poorly managed routes. The Des Moines metropolitan area has many miles of four-lane, undivided arterials constructed when less was known about the importance of managing access to adjacent land development. This project involved a cooperative effort of the Des Moines Area Metropolitan Planning Organization (Des Moines Area MPO) and the Center for Transportation Research and Education (CTRE) at Iowa State University to develop a comprehensive access management study and program for the Des Moines metropolitan area. The goal of the study is to use the knowledge developed to make improvements that will reduce access-related crashes. It is also anticipated that this project will help local officials make better decisions about access management so that future safety and operational problems can be avoided.

Degradação de corantes têxteis e remediação de resíduos de tingimento por processos Fenton, foto-Fenton e eletro-Fenton

In this work the degradation of textile dyes were evaluated, using Fenton, photo-Fenton and electro-Fenton processes. Under optimized conditions Fenton and photo-Fenton processes showed high decolorization capacity of the model dyes. The electro-Fenton process was carried out in an undivided electrochemical reactor (1000 mL) equipped with a carbon-felt cathode (253 cm²) and a platinum gauze anode (6 cm²). Under optimal conditions (J: 1.6 mA cm-2, Na2SO4: 0.075 mol L-1, pH: 3) H2O2 concentration of about 60 mg L-1 was observed. The addition of Fe2+ (15 mg L-1) induces Fenton reactions that permit almost total decolorization of textile dyes.

The site of self-incompatibility action in cupuassu (Theobroma grandiflorum)

Cupuassu (Theobroma grandiflorum (Willd. ex Spreng.) Schumann) is a fruit tree that is attracting attention in Brazil and also in other tropical countries. Its pulp is used to prepare ice-cream, juices, jellies and many other home-made sweets. This species has a very low fecundity, attributed to problems with pollination and self-incompatibility, noted as being restrictive to the agronomic productivity of the species. Controlled pollinations between compatible and incompatible parents were made and flowers were collected at three times: 24, 48 and 72 h after pollinations, during the floral seasons of 1995 and 1998. In flowers collected 24 h after pollination, in both compatible and incompatible crosses, around 70% of ovules showed egg apparatus without evidences of sperm cell delivery; nevertheless some pollen tubes had been observed. Ovaries collected at 48 h showed different behaviors according to the type of cross. In the compatibles, 35% of ovules did not show evidences of gamete fusion. In incompatible crosses this number rose to 50%. Collected ovaries with 72 h, from compatible and incompatible crosses, showed respectively 1.2% and 14.2% of the ovules with the egg apparatus and polar nuclei only. In these ovaries, for the two types of crosses, the presence of sperm nuclei was common and the zygote was still undivided. The incompatibility action is occurring after fertilization, in a late self-incompatibility action.

Elizabeth Bishop’s sounds of sanity

In this article, I examine the implications of rewriting definitions of sanity and insanity through the use of noise, silence, and language,positioningElizabeth Bishop’s short story “In the Village” as a form of resistance against traditional readings of madness, logocentrism, and identity. I suggest that by writing her characters as undivided from the world of sound, Elizabeth Bishop’s story shifts understandings of insanity, which is often conceptualized through denials of agency, allowing her characters to escape in noises and hesitations in language and communication. “In the Village” avoids silencing the “insane” mother through her placement in a caesura of sound and silence. This article avoids a biographical reading of “In the Village,” which is often connected with her own mother’s “mental breakdown,” because Bishop’s writing would have been as much affected by her conscious awareness of her past as it was by the unconscious impulses and histories of writing in the West. Rather, I take into account Bishop’s own personal history as well as the repetitions that reflect a placement in a tradition appearing in the story itself. Using this particular lens, I believe a rereading of “In the Village” is in order, where the “mad mother” is not silenced by the oppressive social structures that control the insane,” but she instead finds escape in the multitudes of sounds that associate with her, erasing the power of language and opening a new world where agency exists in a scream or in a striking hammer.

A new species of Tontelea from Amazonian Peru and Ecuador, and notes on the Tontelea attenuata species group (Celastraceae, Hippocrateoideae)

Tontelea fuliginea differs from other species whose stamens alternate with undivided stigma-lobes by its profusely ramified, many flowered, and densely dirty-brown puberulous inflorescences. This paper also provides a synopsis and key of the group of species with alternate stamens and 3-lobed stiomas with undivided lobes (T. attenuata group). Four lectotypes are designated for previously published names: Tontelea longifolia, Tontelea micrantha, Tontelea corrugulata, and Salacia micrantha var. lancifolia.

Cytogenetics and embryology of Eupatorium laevigatum (Compositae)

Embryological studies indicate Eupatorium laevigatum to have Antennaria type diplospory with precocious embryony. The embryo sac is of the Polygonum type and the polar nuclei fuse before anthesis (maturation of the stamens). Endosperm development is autonomous and the central cell divides only after the initial stages of embryo formation. It is estimated that about 10% of the florets in anthesis contain an undivided egg which can be used for sexual reproduction. The study of microsporogenesis revealed abnormalities in chromosome pairing which result in the formation of univalents, bivalents, trivalents and higher polyvalents, with the consequent production of lagging chromosomes, unbalanced nuclei, micronuclei and sterile pollen. We found that, as represented by the material studied, E. laevigatum is an autohexaploid (2n = 6x = 60) in which each chromosome of a basic set of ten chromosomes is repeated six times and that E. laevigatum is an essentialy obligate apomictic.

Roots, leaves and scapes anatomy of species of Paepalanthus subgenus Platycaulon (Eriocaulaceae)

The anatomical features of roots, leaves and scapes of the subgenus Platycaulon, genus Paepalanthus (Eriocaulaceae) that grow in the Brasilian rupestrian fields of Serra do Cipo - MG - Brazil were studied. The following main anatomical features were found: epidermis cells of varied thicknesses, chlorenchyma with compact or spread organization and leaf margin shape in the leaves; the scapes with continuous or discontinuous endodermis, divided or undivided pericycle, vascular bundles absent in the cortex and in the pith. These anatomical characteristics of the leaves and scapes occur in different species and can be used to separate them into Divise or Conferti sections. It was possible to confirm the proposed taxonomy based only on the morphological characteristics. Other anatomical features such as: presence or absence of air in the cortex roots and hypodermis which originate water parenchyma reserves in the mesophyll, can be an adaptative response that plants towards produce the environmental factors in this ecosystem.

Ablation of the ability to control the right-to-left cardiac shunt does not affect oxygen uptake, specific dynamic action or growth in the rattlesnake Crotalus durissus

The morphologically undivided ventricle of the heart in non-crocodilian reptiles permits the mixing of oxygen-rich blood returning from the lungs and oxygen-poor blood from the systemic circulation. A possible functional significance for this intra-cardiac shunt has been debated for almost a century. Unilateral left vagotomy rendered the single effective pulmonary artery of the South American rattlesnake, Crotalus durissus, unable to adjust the magnitude of blood flow to the lung. The higher constant perfusion of the lung circulation and the incapability of adjusting the right-left shunt in left-denervated snakes persisted over time, providing a unique model for investigation of the long-term consequences of cardiac shunting in a squamate. Oxygen uptake recorded at rest and during spontaneous and forced activity was not affected by removing control of the cardiac shunt. Furthermore, metabolic rate and energetic balance during the post-prandial metabolic increment, plus the food conversion efficiency and growth rate, were all similarly unaffected. These results show that control of cardiac shunting is not associated with a clear functional advantage in adjusting metabolic rate, effectiveness of digestion or growth rates. © 2013.

A plurifuncionalidade da segurança alimentar no meio ambiente como dever de solidariedade agroambiental

O presente trabalho trata da análise teórica da plurifuncionalidade da Segurança Alimentar e Nutricional (SAN) no meio ambiente, que se sustenta como um dever de solidariedade agroambiental. O trabalho foi dividido em três partes, cada uma com dois capítulos, que foram desenvolvidos inicialmente com o estabelecimento do contexto em que se encontram os assuntos abordados, e finalizados com observações acerca das principais ideias estudadas, até a elaboração de considerações finais, que demonstram os resultados alcançados pelo trabalho. Utiliza-se a metodologia teórica e o raciocínio indutivo-crítico, pois se parte do estudo de um fenômeno individualizado, a SAN, para se prejetarem hipóteses que considerem seus efeitos e interações com o meio ambiente natural, para ao final buscar generalizar as soluções encontradas, notadamente a solidariedade em sua dimensão de dever jurídico. Procura-se sustentar a argumentação com obras de referência bibliográficas e outras produções científicas de entidades nacionais e estrangeiras. Discute-se introdutoriamente alguns motivos que levaram à realização da tese, quais sejam os graves problemas que envolvem a alimentação humana na contemporaneidade, destaca sua aproximação com os direitos humanos, especialmente com o princípio da solidariedade e suas características de transdisciplinaridade metodológica, que gera necessariamente efeitos em vários outros campos do conhecimento. São revisados criticamente conceitos firmados pela Organização das Nações Unidas para Agricultura e Alimentação (FAO), especialmente os referentes ao direito à alimentação, direito a estar alimentado, soberania alimentar, Segurança Alimentar e Nutricional (SAN), desnutrição, subnutrição e má nutrição. Considera-se a SAN em sua dimensão plurifuncional porque implica necessariamente em repercussões éticas e jurídicas no âmbito dos direitos humanos, a partir da ideia teórica da solidariedade, que é estudada desde a sua formação antiga, quando associada à virtude, até à modernidade e a aproximação com a política e o direito, entendida no presente como princípio que sustenta o dever jurídico ligado à gestão racional de bens ambientais voltados à alimentação, delimitados em especial no direito agroambiental, percebendo-se a solidariedade então como fundamento de direitos, valor superior qualificada pela fraternidade, e ao mesmo tempo prevista em documentos internacionais de direitos humanos e em diversas constituições. Os interesses difusos são necessariamente examinados, pois a SAN é um interesse geral da sociedade humana, e implica na preservação dos bens ambientais alimentares, considerados indivisíveis na visão solidária, que deve ser integrada aos valores liberdade e igualdade, tornando-os princípios com interpretação mais humana, limitando seu exercício absoluto e ainda justificando-os. A ideia de solidariedade faz com que seja possível chegar aos direitos partindo do dever agroambiental e, diante das várias correntes teóricas que tratam do dever jurídico, considera-se que seja autônomo em relação ao direito subjetivo, mas traduzindo deveres ligados a finalidades sociais, de interesse público, que se manifestam em ambiente democrático, podendo o dever agroambiental ser considerado fenômeno com raízes de ética pública, com elevados valores ambientais, decisivos em sua dimensão jurídica de obrigações e responsabilidades, de todos em relação a todos, inclusive com normas objetivas nacionais e internacionais de proteção de bens agroambientais. Sustenta-se que nesse sentido a ética pública ligada à ética ambiental pode ser decisiva na observância ao direito, para além do convencimento meramente externo, mas enquanto manifestação também interna, ética, que carrega de sentido o dever jurídico solidário ligado à plurifuncionalidade da SAN. Também são elaboradas críticas à tradicional argumentação acerca dos direitos das gerações futuras, pela imprecisão e incerteza científica que os cinge, afastando-os da possibilidade de figurarem como objeto do direito, para assentar que os direitos de que se falam são precisamente traduzidos como deveres das gerações presentes, sendo estes deveres o vínculo jurídico entre gerações sucessivas. Nesse sentido, a solidariedade intergeracional passa a ter um liame jurídico contínuo, estudado através da teoria dos direitos fundamentais, o que lhe confere como característica a fluidez entre as gerações, e que por isso exige o aproveitamento racional dos recursos ambientais naturais, amparado nos princípios da precaução e informação, na ética da responsabilidade dirigida a todas as gerações, que demanda a incorporação de longo tempo nas ações humanas, que possibilite a ampla educação ambiental, e o desenvolvimento do pensamento altruísta, transtemporal, que considere problemas ambientais transfonteiriços e os bens ambientais naturais finitos, sendo indispensável conscientização da geração presente e de sua classe política para a afirmação da solidariedade. Estuda-se ainda que o dever de gestão racional dos bens ambientais naturais alimentares é dever de solidariedade, pois se considera que cada indivíduo usa uma parcela imaterial e indivisa desse bem coletivo, que pode ser público ou privado, mas que se sujeita à solidariedade. Nesse contexto só prevalece o direito de propriedade, em relação aos seus atributos tradicionais, se o objetivo comum de preservação dos bens ambientais alimentares não fornecer uma justificativa suficiente para impor readequação da atividade, abstenção de conduta, ou mesmo medidas sancionadoras decorrentes de responsabilização objetiva. Finalmente, enquanto contribuição científica, o trabalho apresenta um ensaio para a construção das características do dever de solidariedade agroambiental, quais sejam, o seu objeto e os sujeitos, a sua estrutura, que abrange a natureza das obrigações dele decorrente, e o regime principiológico. A conclusão geral apresentada é que o dever de solidariedade agroambiental, demonstrado sua ocorrência pela plurifuncionalidade da SAN, corresponde à ideia de justiça e moralidade política, fenômeno no qual é percebida intensa conexão entre o direito e a ética ambiental, compreensão relevante para resolução de conflitos que envolvam alimentação humana e a utilização de bens ambientais naturais.
