Conhecer a percepção da população de uma capital do Brasil central, considerando a segurança e mobilidade no trânsito foi o objetivo deste estudo. O mau comportamento dos condutores, a falta de atenção e o desrespeito às leis de trânsito foram as principais causas para os acidentes, e foram apontadas prioridades para melhorar o trânsito.
La condición de doble periferia en unidades subestatales
Authors: Juste Stella Maris
Published: September 2017

El presente artículo investigativo se propone un acercamiento teórico al concepto de doble periferia como el condicionamiento que determina la gestión internacional de algunas unidades subestatales Tal condicionamiento se circunscribe a las circunstancias ambientales, económicas y políticas que determinan un entorno desde el cual los departamentos, regiones, provincias, municipios, alcaldías, landers, entre otros, se sitúan y despliegan su accionar internacional respecto del Estado del cual forman parte, y respecto del sistema internacional. En el presente estudio se tomarán como casos la provincia de Jujuy (Argentina), el departamento de Tarija (Bolivia) y la región de Tarapacá (Chile). La existencia de asimetrías en el sistema internacional y en el interior de los Estados lleva a pensar en estructuras que condicionan y caracterizan el accionar internacional de diversos actores, siendo las unidades subestatales el centro de este estudio. La situación de doble periferia es el marco desde el cual las unidades subestatales despliegan su gestión internacional en búsqueda de oportunidades que permitan superar los condicionamientos estatales y sistémicos.

Authors: Gomes Flavia de Faria , Silva Christian Luiz da
Published: September 2017

O estudo visa à dinâmica da controvérsia em torno do licenciamento ambiental de pequenas centrais hidroelétricas (PCHs) no Paraná. Caracteriza-se como qualitativo, baseado em estudos de caso – com informações provenientes de estudos do Instituto Ambiental do Paraná, da Agência Nacional de Energia Elétrica e da mídia local. Verifica-se, em suma, que o problema não está sobre a capacidade do licenciamento, mas na incapacidade de gestão deste, ou seja, está sobre os seus gestores; e que a identificação do arranjo institucional demonstra as possibilidades de melhoria do instrumento.
Impact of cherry, acacia and oak chips on red wine phenolic parameters and sensory profile
Authors: Tavares Mariana , Jordão António M. , Ricardo-da-Silva Jorge M.
Published: September 2017

Aim: The evolution of global phenolic parameters and the sensory profile of a Portuguese red wine aged for 90 days in contact with wood chips from different species were evaluated.

Methods and results: For this purpose, wood chips from cherry (Prunus avium), acacia (Robinia pseudoacacia) and two oak species (Quercus petraea and Quercus pyrenaica) were added to a Portuguese red wine. Various global phenolic parameters of red wines were studied during the aging process (90 storage days). In addition, a sensory analysis was made after the 90-day aging period to determine the impact of the use of different wood chip species on red wine sensory profile. The results showed that during the aging period, only a few differences were detected between the wines. However, after 90 aging days, in general the wines aged in contact with cherry wood tended to have the lowest values for several phenolic parameters. For sensory parameters, the wine aged in contact with French oak chips showed significantly higher scores for several aroma descriptors, while for visual and taste descriptors no statistical significant differences were found between the wines.

Conclusion: At the concentration used (3 g wood chips/L wine), the different wood chip species studied had no clear influence on the evolution of the majority of the red wine phenolic parameters. However, from a sensory point of view, the use of different wood species induced greater differentiation, especially for aroma descriptors.

Significance and impact of the study: The outcomes of this study would be of practical interest to winemakers and regulatory institutions since they could improve the knowledge of the impact of alternative wood chip species, namely acacia and cherry, on red wine quality.

Published: September 2017

INTRODUÇÃO: As hepatites virais são consideradas as principais doenças hepáticas, podendo levar a quadros mais graves, como a cirrose e o carcinoma hepatocelular, tornando-se um importante problema de saúde pública. Tem distribuição global com áreas de altos índices de endemicidade, sobretudo em países asiáticos. Os principais agentes envolvidos são os vírus da hepatite A, B, C, D, E. O vírus da hepatite B e C se destacam nesse meio devido à grande capacidade de cronificação. As formas de transmissão são basicamente através do contato com fluidos corporais infectados, através de transfusões sanguíneas, uso de drogas injetáveis, transmissão vertical, etc. METODOLOGIA: Trata-se de um artigo de revisão no qual, a partir das palavras “hepatite B” e “hepatite C”, foi realizado busca por periódicos nos bancos de dados: PubMed, Scielo, Portal Periódicos CAPES e Google acadêmico. CONCLUSÃO: As hepatites B e C podem se apresentar apenas de forma aguda, ou podem se cronificar. O diagnóstico geralmente é realizado tardiamente, pois, na grande maioria dos casos apresenta-se oligossintomáticas ou até mesmo assintomática. O diagnóstico é feito através de exames sorológicos e quantificação viral através do PCR. O tratamento é basicamente sintomático, porem nos casos crônicos, é indicado uso de medicações, como interferons peguilhados e análogos de nucleosideos.

INTRODUCTION: Viral hepatitis are considered as one of the major liver diseases, being able to lead more severe outcomes, such as cirrhosis and hepatocellular carcinoma becoming an important public health problem. It has global distribution with areas of high endemicity, especially in Asian countries. The main agents involved are hepatitis A virus, B, C, D, E. The hepatitis B and C viruses stand out in the middle of a chronicling ability. As the transmission forms are basically through contact with infected body fluids, through blood transfusions, injecting drug use, vertical transmission, etc. METHODOLOGY: This is a review article, from the words "hepatitis B" and "Hepatitis C", was carried out by search for journals in databases: PubMed, Scielo, Portal Periodicos CAPES and Google academic. CONCLUSION: The hepatitis B and C can either be only a form of acute, or can be chronic. Therefore, the diagnosis is often late, since in the vast majority of cases it is oligosymptomatic or even asymptomatic. The diagnosis is made through serological tests and viral quantification through PCR. The treatment is basically with symptomatic, such as pegged interferon’s and nucleoside analogs.

Micro, Small and Medium Enterprises (MSMEs) have a very significant impact on the Indonesian economy. Therefore, it is important to do research in order to determine the condition of current performance and analyze the factors that influence the development of MSMEs and to provide strategic advice on the development of MSMEs in Surakarta. Long-term goal is the development of MSMEs in Surakarta in the future as measured from the increase in sales, so the SMEs entrepreneurs increase revenue, reduce unemployment and ultimately can reduce the level of poverty in Surakarta by particular and Indonesia by general.

The study took a sample of 91 MSMEs entrepreneurs spread across five districts in the city of Surakarta. Each district taken by SMEs entrepreneurs with purposive sampling method. Mapping MSMEs performance conditions were analyzed descriptively to describe various aspects such as firm age, labor, raw materials, capital and problems faced. While the factors that influence the development of MSMEs were statistically analyzed with multiple regression models.
The results showed that the performance of the mapping conditions of SMEs in Surakarta average face problems in raw material costs, labor costs and promotion costs, as well as in the capital. Capital cost and total variable evidenced by the positive and significant impact on the development of the business. While the age factor and the company's workforce does not have a significant influence on the development of SME. It can be understood that the main problem in SMEs are raw materials and capital. There is a type of business that is not easy to obtain raw materials in the market. Therefore SME development strategy with more emphasis on the supply of raw material, marketing, production, and capital.

The aim of this research is to investigate the relationship between perceived sosial identity as an older worker, job characteristic, social support and burnout and attitude towards retirement and work. A total of 400 questionnaires were collected from workers over the aged of 50, and they were working in Ministry of Communication and Information, Jakarta. Purposive sampling were used in this research. Stuctural Equation Model (SEM) analyses were performed to test the influence of social identity as an older worker, job characteristic, social support and burnout to attitude towards retirement and work. Age, gender, marital status and education were used as demographics variables.

The result show that identification with older worker was positively related to intergenerational competition, and negatifly related to career development, bridge employment, devaluation work dan intention to early retirement. Intergroup permeability was positively related to intention to early retirement. Job characteristic was positively related to career development, intergenerational competition, bridge employment, devaluation work, burnout and intention to early retirement. Social support was negatifly related to burnout, and burnout was positively related to intention to early retirement. Intergroup permeability was not related to career development, intergenerational competition, bridge employment and devaluation work because older worker in this research felt intergroup unpermeability. It means older workers in this study feel the ageism and burnout at their workplace.
Dynamic links between ICT, transport energy, environmental degradation and growth: empirical evidence from Tunisia
Authors: Ben Mbarek Mounir , Zghidi Nahed
Published: September 2017

The transport sector, particularly road transport, is a major factor in the overall emissions balance of the substances involved in air pollution for the majority of developing countries. This paper investigates the dynamic links between information and communication technology (ICT), transport energy, environmental degradation and growth for Tunisia. The authors used a Johansen co-integration analysis to determine this econometric relationship using data during 1990–2015. In order to test the Granger causality links in the short and long run, a panel Vector Error Correction Model is used. The variance decomposition is used to confirm the existing links between the different variables. Different results are found. These findings show the existence of bidirectional in short- and long-run causality between transport energy and CO2 emissions. By cons, ICT does not minimize significantly pollution in Tunisia. These findings are very important for the transport sector and in terms of the choice of government policy decisions in order to minimize the pollution.

Introducción: El objetivo fue determinar la relación entre las concentraciones séricas de calcio (Ca2+), ácidos grasos no esterificados (AGNE) e insulina preparto con pérdidas en la producción de leche (PL) en el inicio de la lactancia.Método: Doscientas cuarenta y tres vacas Holstein-Friesian (780 ± 36 kg PV; con más de dos lactancias) fueron muestreadas por punción coccígea varias veces antes, durante y después del parto. Para cada muestreo y cada metabolito, las concentraciones séricas se estratificaron con umbrales y se relacionaron con la PL.Resultados: Cuando los niveles de Ca2+ fueron bajos 10 días antes del parto y se relacionaron con la PL a los 10 días posparto, se observó que el 77.11% de las vacas perdieron 2.20 kg de leche; mientras en el día 20, el 66.41% de las vacas perdieron 1.40 kg animal-1 día-1. Por el contrario, cuando los AGNE fueron altos 10 días antes de parto y se relacionaron con PL, 67.40% de las vacas mostraron riesgo de perder 0.80 kg, mientras que a los 20 días posparto, el 22.00% de las vacas perdieron aproximadamente 0.90 kg vaca-1 día-1. La determinación de insulina preparto baja y PL en los días 10 y 20 de lactancia indicó que 6.02% de las vacas perdieron 0.80 y 0.70 kg de leche animal-1 día-1 para los días 10 y 20 de lactancia.Conclusión: En conclusión, niveles bajos de calcio, AGNE alto e insulina baja en sangre, obtenidos 10 días antes de parto fueron asociados con pérdidas en producción de leche en los días 10 y 20 después del parto. También se observó que los niveles bajos de calcio podrían causar mayores pérdidas de leche que los niveles altos de ácidos grasos no esterificados y las concentraciones bajas de insulina preparto.
Urban stormwater inundation simulation based on SWMM and diffusive overland-flow model
Authors: Chen Wenjie , Huang Guoru , Zhang Han
Published: September 2017

With rapid urbanization, inundation-induced property losses have become more and more severe. Urban inundation modeling is an effective way to reduce these losses. This paper introduces a simplified urban stormwater inundation simulation model based on the United States Environmental Protection Agency Storm Water Management Model (SWMM) and a geographic information system (GIS)-based diffusive overland-flow model. SWMM is applied for computation of flows in storm sewer systems and flooding flows at junctions, while the GIS-based diffusive overland-flow model simulates surface runoff and inundation. One observed rainfall scenario on Haidian Island, Hainan Province, China was chosen to calibrate the model and the other two were used for validation. Comparisons of the model results with field-surveyed data and InfoWorks ICM (Integrated Catchment Modeling) modeled results indicated the inundation model in this paper can provide inundation extents and reasonable inundation depths even in a large study area.
Kara doczesna w perspektywie Bożego miłosierdzia
Authors: Wiśniewski Sebastian
Published: September 2017

Jedną z trudności nasuwających się przy szukaniu odpowiedzi na pytanie, jakie jest znaczenie kary doczesnej za grzechy, pozostaje bliski związek tego problemu z pytaniem o sens cierpienia w ogóle. Celem niniejszego artykułu nie było jednak szukanie odpowiedzi na pytanie o znaczenie cierpienia, ale na specyficzny jego zakres związany z karą doczesną za grzechy, w kontekście Bożej sprawiedliwości i miłosierdzia. Poszukiwania teologiczne pozwoliły wykazać, że jedną z odsłon miłosierdzia Bożego w życiu człowieka jest doczesna kara za grzechy. Wynika ona zarówno z Bożej sprawiedliwości, jak i z Bożego miłosierdzia. Ponieważ Bóg jest sprawiedliwy, jest także wierny swojej miłości do człowieka, zatem zawsze otwiera nowe perspektywy powrotu człowieka do wierności przymierzu. Sprawiedliwość zatem przejawia się w miłosierdziu, a miłosierdzie nie boi się posłużyć karą doczesną, byle by ocalić człowieka nie tylko na chwilę, ale na całą wieczność. Bóg jest dobry. Jest sprawiedliwy i miłosierny. Sprowadza sprawiedliwą karę doczesną, ale nie ma ona charakteru niszczącego człowieka, tylko zadanie przestrzeżenia człowieka przed śmiercią grzechu (zob. Rz 6, 23) lub sprowadzenia go z powrotem na drogę wierności przymierzu z Bogiem przez nawrócenie (zob. Ez 18, 32), lub też wychowanie go do życia zgodnego z warunkami przymierza (Ap 3, 19). Miłosierdzie Boże nie sprzeciwia się w żaden sposób Bożej sprawiedliwości i nie oznacza, że Bóg rezygnuje z karcenia tych, których kocha. Przeciwnie – kara pojawia się właśnie dlatego, że Bóg okazuje człowiekowi swoje miłosierdzie.

Published: September 2017

Background:

Traditional Beninese fermented food Degue is widely consumed in Benin and other countries in West Africa. It was originally made from milk and millet flour, but currently other cereals are used as well. Nowadays, Degue production occurs by spontaneous fermentation in individual households and information about the microorganisms involved is currently limited.

Objective:

The microbiota of Degue from Benin has not been studied so far, but its growing production in the country sets a demand for revealing the biodiversity of the microbial population involved in the fermentation process in order to take future steps for development of industrial technology and offer products with improved quality and safety.

Method:

In the present study, yeast and lactic acid bacteria from raw materials for Degue production and from several Degue products were isolated and identified by molecular methods including RFLP and ITS1-5.8S-ITS2 rRNA gene sequence analysis in yeasts, and 16S rRNA gene sequence analysis in lactic acid bacteria.

Results:

Lactic acid bacteria isolates were assigned to eight species within the generaLactobacillus,Enterococcus,Pediococcus,StreptococcusandWeisella. Four species of yeasts were found in Degue:Cyberlyndnera fabianii,Candida glabrata,Kluyveromyces marxianus, andMeyerozyma caribbica.

Conclusion:

The microbial population revealed is unique to Beninese Degue and needs further characterization for development of defined starter cultures.

Published: September 2017

Introduction:

For technical renovation of the thermal plant, one frame structure workshop of 50,000 m2 construction area and one reinforcement concrete chimney of 150m height shall be demolished by blasting in the same time. The engineering environment is very complicated and the accommodation space for the structures collapse is limited. Therefore, the collapse sequence, direction, scope of the structures must be accurately controlled to ensure the safe operation of the adjacent generator unit and transformer station.

Methods:

By taking technical measures of theoretical analysis and numerical simulation etc., as well as research on structures collapse process and initiation system, it puts forward the technology of bidirectional folded collapse of the workshop and it uniquely adopts the initiation system that combined with “half-second delay inside drilling” and “millisecond delay outside drilling”.

Results and Conclusion:

Additionally, by using of the integrated vibration reduction technology in combination of the blasting ruins, buffer ditch and damping ditch, it has safely accomplished the blasting demolition work in high efficiency. Besides the blasting demolition vibration signal is collected and analyzed. The success of the blasting demolition will become valuable reference to other similar works.

Authors: Gustafsson Christina Hassel , Östberg Anna-Lena
Published: September 2017

Objectives:

The purpose of this study was to investigate the experiences of employees regarding the merger of clinics within the Public Dental Service (PDS), Västra Götaland Region, Sweden.

Methods:

Employees (dentists, dental hygienists, dental nurses) affected by both administrative and geographical mergers of dental clinics answered a web-based survey about experiences and effects of the merger process (n = 99, 47%). The Swedish short-form version of “The Nordic Questionnaire for Psychological and Social Factors at Work” (QPSNordic), the QPSNordic-34+ was used. Chi-squared tests and logistic regression analyses were used.

Results:

Two thirds of the participants were aged ≥ 50 years. The respondents stated that the reasons for the merger were often made clear (78%). Satisfaction with and involvement in the merger process received lower scores (45%). Work was often perceived as stressful, irrespective of the merger. Job demands and engagement scored positively, but control at work was given a low score (one fifth stated fairly high or high control). Dentists (OR 5.9; 95%, CI 1.1-32.3), but not dental hygienists (OR 2.8; 95%, CI 0.9-9.0), indicated stress significantly more often than dental nurses (reference) (adjusted for age and gender).

Conclusion:

Employees in the Public Dental Service (PDS) in a Swedish region had mainly positive experiences after the merger of clinics; however, their involvement in the process was low. Work demands were perceived as high. These findings should be considered when planning mergers in dental organizations.

Published: September 2017

Introduction:

In this study, we evaluated the antimicrobial potential of cultivable endophytic fungi associated withHancornia speciosaGomes stem bark.

Methods and Materials:

Plant samples were collected in rainy (July 2010) and dry (January 2011) seasons. In total, 116 endophytic fungi strains were isolated from 90 fragments (64.4% frequency of colonization). Higher fungi frequency was observed in the rainy season (84.4%). The strains were grouped into 14 species; the most frequent werePhoma cava(13.8%),Colletotrichum gloeosporioides(12.1%), andLasiodiplodia theobromae(11.2%). Fungal diversity was similar in both the seasons. Among the 116 strains, 39 (33.6%) showed antimicrobial activity in preliminary screening. The ten most active isolates were subjected to semi-solid fermentation using rice or corn as substrates. Methanolic extracts were obtained from each fermentation medium and the minimum inhibitory (MIC) and minimum microbicide concentrations (MMC) were determined.

Results:

The best antimicrobial results (MIC < 100 µg/mL) were observed for fungi strains grown in rice medium:Aspergillus nigerFHS061 againstProteus mirabilis(MIC = 19 µg/mL) andStaphylococcus aureus(MIC = 39 µg/mL). These strains also showed good results when cultivated in corn medium againstP. mirabilis(MIC = 78 µg/mL).

Conclusion:

Thus, the stem bark ofH. speciosaharbors diverse endophytic fungi with antimicrobial potential.
Relationship of Dental Hygiene Students’ Engagement Practices to Their Academic Achievement
Authors: Leiken Susan M.
Published: September 2017

Students in many fields have been found to learn more the more they are engaged in both the academic and social aspects of the learning experience. The aims of this study were to determine the level of dental hygiene students’ engagement in their educational programs and in student chapters of the American Dental Hygienists’ Association (ADHA) and to assess the relationship of that engagement to students’ success as measured by cumulative GPA. All 12,000 dental hygiene students (6,000 in the first year and 6,000 in the second year of two‐year programs) enrolled in the 334 accredited U.S. dental hygiene programs were invited to participate in the survey. The ADHA electronically distributed the survey on behalf of the researcher to the students in February 2015. The response rate was 22% (N=2,649); the respondents had a survey completion rate of 94%. Three positive predictors were found to influence student success. The higher the responding students rated the quality of interactions with their faculty members and with their program directors, the higher was their mean GPA. In addition, holding a higher education degree was found to be a significant predictor of academic success. This study's results provide dental hygiene educators with a better understanding of how dental hygiene student engagement relates to academic achievement and may encourage faculty members to improve their strategies for delivering instruction. Future research should review enhanced student engagement practices as they relate to student success.

Authors: Ettinger Ronald L. , Goettsche Zachary S. , Qian Fang
Published: September 2017

The aim of this study was to determine the number and size of postdoctoral teaching programs in geriatric dentistry in U.S. dental schools and other health professions educational institutions and those programs with Health Resources and Services Administration (HRSA) funding. In 2015, all 67 U.S. dental schools were contacted via email with a questionnaire to ask if they had a postdoctoral program in geriatric dentistry; if they did, they were asked to report the length and size of the program. Directors of all 16 HRSA‐funded geriatric fellowships were also invited to participate in the survey. Fifty‐six of the 67 (83.6%) dental schools and 15 of the 16 (93.8%) HRSA‐funded programs completed the questionnaire. Postdoctoral geriatric dentistry programs were reported in 12 dental schools and six medical institutions, although only six programs were currently accepting fellows. The length of the programs was 12–36 months. The maximum number of residents in any program was ten. The oldest program was in Minnesota; it began in 1981. The newest program was beginning in 2017 at Boston University as a revised version of its previous HRSA‐funded program. The loss of HRSA funding has had a major negative impact on the number of training programs. Future research is needed to determine how the loss of HRSA‐funded programs has affected the availability of educators in geriatric dentistry for dental schools and the services provided to the geriatric community.
Incidence and Determinants of Dental Implant Failure: A Review of Electronic Health Records in a U.S. Dental School
Authors: Hickin Matthew Parker , Shariff Jaffer A. , Jennette Philip J. , Finkelstein Joseph , Papapanou Panos N.
Published: September 2017

The aim of this study was to use electronic health care records (EHRs) to examine retrospectively the incidence of and attributes associated with dental implant failures necessitating implant removal in a large cohort of patients treated in the student clinics of a U.S. dental school over three and a half years. EHRs were searched for all patients who received dental implants between July 1, 2011, and December 31, 2014. Characteristics of patients and implants that were actively removed due to irrevocable failure of any etiology (“failure cohort”) during this period were compared to those of all other patients who received dental implants during the same time frame (“reference cohort”). Differences in the frequency distribution of various characteristics between the failure and reference cohorts were compared. Of a total 6,129 implants placed in 2,127 patients during the study period, 179 implants (2.9%) in 120 patients (5.6%) were removed. In the multivariate analysis, presence of a removable (OR=2.86) or fixed temporary prosthesis (OR=3.71) was statistically significantly associated with increased risk for implant failure. In contrast, antibiotic coverage (pre‐ and post‐surgery OR=0.16; post‐surgery only OR=0.38) and implants of certain manufacturers were associated with lower risk of implant failure. In this sizeable cohort of patients receiving care in dental student clinics, the review of EHRs facilitated identification of multiple variables associated with implant failure resulting in removal; however, these findings do not suggest causative relationships. The adopted analytical approach can enhance quality assurance measures and may contribute to the identification of true risk factors for dental implant failure.
12‐Year Use of a Digital Reference Library (VitalBook) at a U.S. Dental School: Students’ and Alumni Perceptions
Authors: Spielman Andrew I. , Maas Elizabeth , Eisenberg Elise S.
Published: September 2017

Digital textbooks are being used to reduce production and storage costs of printed copies, enhance usage, and include search capabilities, but the use of digital texts is not universally accepted. In 2001, the New York University College of Dentistry introduced a digital reference library, the VitalBook. Beginning in 2005, the college annually surveyed senior students and, from 2012, also surveyed alumni on their opinions and extent of use of the VitalBook. The aim of this study was to evaluate 12 years of students’ perspectives and three years of alumni perspectives on the value of the VitalBook to their dental educational experience. Students were asked how frequently they used the VitalBook, if it was a good investment, if they would use it after graduation, and if they would recommend it to others. Alumni were asked the last three questions. This study reports the results from 4,105 students over 12 years (average response rate 95.3%) and 184 alumni over three years (average response rate 17.4%). The results indicated that students used the VitalBook on average 24% of their study time, but they were split regarding the other questions. The majority opinion in 2005 was negative on all questions. These opinions shifted to become more favorable to a peak in 2010, but declined since then to a more negative overall view of the VitalBook. A split opinion among students continued through 2016, with fewer recommending it although more considered it a good investment with plans to use it after graduation. Alumni mirrored their responses as students. These results suggest that, as more flexible and dynamic digitized reference systems emerge, the use of student‐paid traditional digitized textbooks may become an even less favored choice.
Complejos estomáticos de veinticuatro taxa de Mimosa (Leguminosae) presentes en México
Authors: Montaño-Arias Susana Adriana , Camargo-Ricalde Sara Lucía , Grether Rosaura
Published: September 2017

Antecedentes y Objetivos: La clasificación infragenérica de Mimosa (Leguminosae) es compleja. La distinción entre los taxa se basa en caracteres morfológicos y anatómicos. Diversos autores mencionan que los complejos estomáticos son útiles en la taxonomía vegetal. En Mimosa, la anatomía foliar es un campo poco explorado, por lo que se desconocen los complejos estomáticos de más de 90% de sus taxa. Por lo anterior, el objetivo de este trabajo fue determinar, con fines taxonómicos, el tipo de complejo estomático de 24 taxa de Mimosa presentes en México.Métodos: Se seleccionaron 24 taxa de Mimosa presentes en México. Por taxon, se eligieron tres individuos con altura y cobertura similar; se recolectó el mayor número de pinnas de las hojas; éstas se mezclaron para obtener una muestra compuesta por individuo. Se eligieron los folíolos de la parte media de cada pinna y se lavaron con agua destilada. Una vez aclarados, se deshidrataron y se elaboraron preparaciones permanentes con resina sintética.Resultados clave: Este estudio abarcó tres de las cinco secciones de Mimosa. La sección Batocaulon fue la mejor representada, con la mayoría de los taxa pertenecientes a las series Acanthocarpae y Boreales. Se encontraron folíolos anfistomáticos en 22 de los taxa; mientras que los otros dos tienen folíolos hipostomáticos. Los 24 taxa estudiados presentan complejos estomáticos de tipo paracítico; aunque M. goldmanii, M. luisana, M. monancistra y M. pringlei var. pringlei, además de tener este tipo de complejos, muestran los de tipo anisocítico, excepto en M. benthamii var. benthamii que son anomocíticos.Conclusiones: Los taxa estudiados se agruparon considerando tres caracteres con valor taxonómico: i) folíolos hipostomáticos vs. folíolos anfistomáticos, ii) presencia de un tipo de complejo estomático vs. dos tipos de complejos estomáticos, y iii) complejos estomáticos paracíticos y anisocíticos vs. complejos estomáticos paracíticos y anomocíticos.

Durante el verano del 2002 la colecta de polen y la distribución de las abejas (Apis mellifera L.) pecoreadoras fueron estudiadas en el cultivo de melón (Cucumis melo L., cv Cruiser ) bajo condiciones de riego por goteo y acolchado plástico. El lote experimental estuvo localizado cerca del Campo Experimental La Laguna del INIFAP, en el municipio de Matamoros, Coahuila, México. Dos experimentos se realizaron en el mismo predio, en lotes separados 800 m por una huerta de nogal. Ambas superficies de melón fueron sembradas en la misma fecha. Experimento N° 1. Al inicio de la floración se colocaron nueve colmenas en tres hectáreas de cultivo. Cada colmena contó con una trampa de polen tipo Ontario modificada. El polen se colectó cada hora de cada colmena un día por semana de las 8:30 hr a las 14:30 hr durante las cuatro primeras semanas de floración del cultivo. Experimento N° 2. Tres semanas después del inicio de la floración se colocaron 30 colmenas en un campo de melón de diez hectáreas. En cuatro surcos de 105 m de longitud se marcaron transectos de diez metros a 25, 50, 75 y 100 metros de distancia del apiario. Las abejas pecoreadoras fueron contadas simultáneamente en cada transecto cada media hora de las 7:30 hr hasta las 20:30 horas, el mismo día en que fue colectado el polen de la tercera semana de floración. La colecta de polen fue mayor temprano por la mañana (22.6 g por colmena), disminuyendo a una cantidad media de las 9:30 hr (13.7 g), 10:30 hr (12.5 g) a las 11:30 hr (9.5 g) y permaneciendo baja desde las 12:30 hasta el mediodía (menos de 2.6 g por colmena; p<0.05). El patrón de distribución mostró que las abejas se presentaron en el cultivo de melón después de las 8:00 hr y alcanzaron su máximo entre las 10:30 hr y las 14:30 hr cuando las abejas iniciaron su disminución hasta el cese de los vuelos a las 20:30 hr. No se encontraron diferencias significativas en el número de abejas pecoreadoras a las diferentes distancias del apiario que fueron evaluadas.

Como una especie amenazada, las poblaciones de gacela Iraní han disminuido durante las décadas pasadas. El conocimiento de la ecología de la gacela que incluye sus hábitos alimentarios y las asociaciones del habitat que utiliza son centrales para cualquier tipo de esfuerzo de conservación. La ecología de gacelas es pobremente conocida y las asociaciones del habitat de ésta y otras especies de gacelas no se han estudiado en Irán. La gacela Iraní en el habitat de 6000 ha (en el Parque Nacional de Bamoo ) se estudió durante el periodo de Otoño e Invierno. El uso del habitat fue relacionado con las comunidades de vegetación y su composición, por medio del conteo de los grupos fecales cada dos meses: de septiembre/octubre 2004 a marzo/abril 2005, en 15 transectos permanentes de 2.5 x 200 metros que se localizaron al azar. La densidad de los grupos fecales fue muy similar en cuatro comunidades vegetales, mientras en la comunidad vegetal 1 en la que Scariola orientalis era dominante, fue significativamente menor. La densidad de gacelas está positivamente asociada con tres especies de arbustos (especie: Astragalus spp., Ebenus stellata , Achillea eriophora con P <0.01, P <0.05, P<0.05, respectivamente) y dos especies de pasto (Poa bulbosa y Aegilops umbellulata, P <0.05) y negativamente asociada con Helichrysum leucocephalum (P <0.01), Scariola orientalis (P <0.01) y Centaurea virgata (P <0.01). Las observaciones acerca de la conducta alimentaria mostraron que las gacelas consumían Bromus danthoniae y Stipa barbata durante el otoño y Astragalus spp., Poa bulbosa, Aegilops umbellulata y Bromus danthoniae durante el invierno.

Published: September 2017

Se registró, entre septiembre de 1994 y marzo de 1995, el uso de embalses por el pato mexicano (Anas diazi Ridway, 1886) en la región de El Llano, entre Aguascalientes y Jalisco en México. El objetivo de este estudio fue determinar cuáles embalses son seleccionados o evitados por esta especie, con base en un análisis de uso-disponibilidad de cuerpos de agua. Los resultados sugieren un uso superior al esperado de los bordos, los cuales se utilizan para almacenar agua que se extrae por bombeo para irrigación, durante el otoño y parte del invierno. Este tipo de almacenamiento de agua puede ser importante para la continuidad del ciclo vital del único anátido residente del Altiplano mexicano. La evaluación e identificación de los cuerpos de agua que son utilizados por encima de su disponibilidad, permitiría proponer estrategias para la conservación y aprovechamiento sostenible de esta especie.

Published: September 2017

Se hizo el estudio anatómico e histológico del sistema digestivo de Stenomacra marginella (Herrich-Schaeffer 1850) para conocer sus adaptaciones y comprender los procesos de digestión y absorción en el mismo. El tubo digestivo de esta especie tiene el mismo patrón estructural general característico de los insectos. Presenta las siguientes diferencias con respecto a otros hemípteros chupadores de savia: ausencia de ciegos gástricos, y membrana peritrófica, presencia de células glandulares unicelulares granulares y tejido glandular rodeando al intestino medio. Esto aunado a las observaciones directas de los insectos alimentándose de diversas fuentes (desechos orgánicos y savia) sugiere que esta especie es omnívora y no fitófaga o polífaga.

Ceraeochrysa sp. nr. cincta (México) (Neuroptera: Chrysopidae) es un depredador con larvas crípticas que atacan diversos artrópodos plaga en frutales de México. Para contribuir al posible aprovechamiento de este insecto benéfico en el control biológico de plagas, esta investigación fue realizada con el objetivo de determinar sus rasgos biológicos y parámetros poblacionales. Los estudios se realizaron bajo condiciones controladas de laboratorio con tres cohortes de 50 individuos de C. sp. nr. cincta. Los resultados mostraron que el tiempo de desarrollo de huevo hasta la emergencia de adultos fue de 29 días, con una supervivencia general de 96%. Los estadísticos demográficos estimados, fueron: Ro = 95, T = 59 días, Td = 8 días y rm= 0.081 hijas/hembra/día. Estos rasgos son similares a los indicados para otras especies de Chrysopidae; en cambio, el porcentaje de hembras fecundadas y fertilidad de huevos fueron menores, y el periodo de preoviposición fue mayor. Estas características reproductivas fueron estudiadas en un experimento subsecuente, donde las hembras permanecieron con diferentes proporciones de machos (1:0, 1:1, 1:2, 1:3 y 1:5) en forma temporal. Excepto por la condición de hembras sin machos (1:0), cuando éstas se mantuvieron en forma temporal con 1, 2, 3 y 5 machos, mostraron un período de preoviposición más corto; también existieron valores altos de hembras en oviposición, fertilidad de huevos y fecundidad. El número de apareamientos bajo las diferentes proporciones de hembras:machos no fue significativamente diferente. Los resultados indican el potencial de C. sp. nr. cincta para ser producida masivamente para su aprovechamiento en el control biológico de plagas en México.
