    Full Text Available El objetivo de la presente comunicación es presentar la información osteométrica correspondiente al esqueleto postcraneal de una muestra de 18 individuos adultos de diferente sexo y edad, provenientes la cuenca del lago Salitroso (N.O. de la provincia de Santa Cruz. Los mismos fueron recuperados a partir de la excavación de chenques y hoquedades naturales sobre roca, con un rango de edades radiocarbónicas situado entre ca. 2500 y 300 años AP. El presente estudio se integra a una investigación de mayores alcances orientada a analizar la evolución de las poblaciones humanas del centro-sur de la Patagonia continental durante el Holoceno tardío. En este estudio se consideraron 45 variables métricas correspondientes a 10 unidades anatómicas del esqueleto postcraneano (húmero, radio, cúbito, clavícula, fémur, tibia, peroné, escápula, sacro y coxal. A nivel de la localidad, se establecieron comparaciones basadas en análisis uni y multivariados entre el conjunto de entierros más antiguo (ca. 2500-1800 años AP con el más reciente (ca. 1000-300 años AP, con la finalidad de detectar diferencias significativas entre ambas submuestras cronológicas. Finalmente, se analizaron los datos regionales en relación con la variabilidad registrada en otras muestras de Patagonia continental (Chubut y sur de Santa Cruz y Tierra del Fuego.

    Full Text Available Se presentan los resultados de los estudios de salud y adecuación fisiológica de la cavidad oral, efectuados sobre una muestra de 30 individuos de distinto sexo y edad, correspondientes a grupos cazadores-recolectores del Holoceno tardío de la cuenca del lago Salitroso (Noroeste de Santa Cruz. Se emplearon técnicas macroscópicas y radiológicas para evaluar la prevalencia de caries, pérdida de dientes antemortem, abscesos y enfermedad periodontal. Asimismo, sólo de forma macroscópica, se relevó la prevalencia de cálculo dental y el grado de desgaste de la corona. Se observaron bajas prevalencias de caries, abscesos y pérdidas de piezas antemortem, altos grados de desgaste y moderadas frecuencias de cálculo dental. Se compararon estos resultados con aquellos obtenidos para otros grupos cazadores-recolectores. Los datos obtenidos en el lago Salitroso coinciden con lo observado para grupos con dietas altamente abrasivas y de bajo contenido de alimentos cariogénicos. Metodológicamente, la inclusión de técnicas radioscópicas permitió refinar el diagnóstico de abscesos, aunque mostró una baja sensibilidad para la detección de caries.

    2005-01-01

    Full Text Available En un trabajo reciente se realizó un estudio de salud bucal en una muestra de restos humanos perteneciente a cazadores recolectores tardíos (entre ca. 1200-350 años AP provenientes de chenques en la cuenca del lago Salitroso (Noroeste de Santa Cruz. Mediante la inspección visual se estudiaron 21 individuos de distinto sexo y edad, observándose bajas prevalencias de caries, abscesos, pérdida de dientes antemortem y altos grados de desgaste dental. Estos resultados coinciden con lo observado en otras muestras de cazadores-recolectores con dietas con una baja proporción relativa de alimentos vegetales ricos en azúcares y almidones. Teniendo en cuenta este antecedente, el objetivo del presente trabajo es ampliar los estudios de salud bucal mediante la incorporación de nuevos casos, nuevas variables (v.g. enfermedades periodontales y la diversificación de las técnicas de análisis utilizadas, principalmente a través del empleo de la radioscopía como técnica complementaria a la inspección visual. Este estudio permitirá, por un lado, estimar la concordancia entre las observaciones obtenidas a través de ambas técnicas de análisis y, por el otro, evaluar la persistencia de las tendencias observadas anteriormente en el comportamiento de estos indicadores

    Full Text Available High mountain lakes and lagoons are not a typical feature of the landscape of the Iberian Peninsula, but rather an exception in the natural environment, therefore its study and conservation presents great interest. This study arises in order to inventory and characterize a set of seventeen lagoon complex located over the provinces of Palencia and León, without any kind of size restriction. Likewise their basins are described, since they are related with them and they will determine their future evolution. Among other results, it should be noted that, despite they are situated at high altitude, they have a complex and varied hydrological network, denoting the high diversity of these systems. The lithology factor seems to affect significantly to the depth of the studied units, however depth and dimensions of the lakes are strongly related with the specific characteristics of their morphogenesis. In general, studied lakes and lagoons appear to be more fragile to possible alterations in their catchments if they are compared with bigger systems studied in the specialized literature.Los lagos y lagunas de alta montaña no son un rasgo típico del paisaje de la Península Ibérica, sino más bien una excepción en el medio natural, por ello su estudio y conservación presenta gran interés. Este trabajo surge con objeto de inventariar y caracterizar un conjunto de diecisiete complejos lagunares ubicados en las provincias de Palencia y León (Cordillera Cantábrica y Sierra de la Cabrera, sin ningún tipo de restricción por tamaño. Así mismo se describen sus cuencas, ligadas con las masas de agua y que determinarán su futura evolución. Entre otros resultados, cabe señalar que, a pesar de su carácter de cabecera, presentan una red hidrológica compleja y variada, denotando la diversidad de estos sistemas. La composición litológica parece incidir significativamente en la profundidad de las unidades, sin embargo la profundidad y dimensiones de

    Full Text Available Comprender el funcionamiento hidrológico y la interacción de los diferentes cuerpos de agua en un área específica es un tema esencial a la hora de planificar el uso racional del recurso hídrico. El objetivo de este trabajo es realizar un aporte en el ámbito metodológico, al evaluar la aplicación conjunta de métodos hidrológicos-limnológicos y de SIG en el estudio de lagos someros, y profundizar en el conocimiento del comportamiento hidrológico de los humedales en ambientes de llanura, tomando como área piloto la laguna La Salada en la Llanura Interserrana Bonaerense. La misma es una laguna somera, permanente y arreica con una extensión de 5,78 km2. En este trabajo se aplican metodologías y herramientas ofrecidas por los SIG para establecer la evolución y el estado de este humedal. Utilizando el Modelo Digital de Terreno del área, se elaboraron perfiles topográficos que muestran la relación entre esta laguna y los cuerpos de agua cercanos, y se realizó el análisis multitemporal de los parámetros morfométricos. Se diseñó una malla de muestreo para establecer la batimetría de la laguna y realizar su caracterización hidrogeoquímica e isotópica. Su composición química es homogénea tanto arealmente como en profundidad. Una variación de conductividad en profundidad, el contenido isotópico y el diagrama de Gibbs, sugieren que un proceso de evaporación domina la química del agua. Los parámetros físico- químicos permitieron establecer la aptitud del agua para distintos usos.

    International audience; Architect Rem Koolhaas and his team from Harvard regard Lagos as an extreme and pathological form of the city in Africa and as a paradigmatic case of a modern avant-garde city. In rehabilitating the informality at work in Lagos, they put forward a romanticized vision of a self-regulatory system working outside state regulation and political influence. In this article I consider that the crisis of urban infrastructure in Lagos is less the result of the weakness of the N...

    Sidelnik, Iván; Asorey, Hernán; LAGO Collaboration

    2017-12-01

    The Latin American Giant Observatory (LAGO) is an extended cosmic ray observatory composed of a network of water-Cherenkov detectors (WCD) spanning over different sites located at significantly different altitudes (from sea level up to more than 5000 m a.s.l.) and latitudes across Latin America, covering a wide range of geomagnetic rigidity cut-offs and atmospheric absorption/reaction levels. The LAGO WCD is simple and robust, and incorporates several integrated devices to allow time synchronization, autonomous operation, on board data analysis, as well as remote control and automated data transfer. This detection network is designed to make detailed measurements of the temporal evolution of the radiation flux coming from outer space at ground level. LAGO is mainly oriented to perform basic research in three areas: high energy phenomena, space weather and atmospheric radiation at ground level. It is an observatory designed, built and operated by the LAGO Collaboration, a non-centralized collaborative union of more than 30 institutions from ten countries. In this paper we describe the scientific and academic goals of the LAGO project - illustrating its present status with some recent results - and outline its future perspectives.

    Full Text Available La relación entre la fluorescencia variable y la fluorescencia máxima (Fv/Fm de las comunidades de algas se ha utilizado comúnmente como una medida de la eficiencia fotosintética del fitoplancton. Dicha eficiencia puede estar afectada por la localización de los ambientes acuáticos en distintas provincias limnológicas. En este trabajo se quiso establecer la diferencia en la relación Fv/Fm entre el lago Boa (150 msnm, Amazonía colombiana y el lago Guatavita (3000 msnm, cordillera oriental de los Andes colombianos. Los promedios de las eficiencias medidas fueron en general bajos (0,212 a 0,367 y 0,089 a 0,32 en los lagos Boa y Guatavita, respectivamente, lo que señala estrés fisiológico para las algas. La eficiencia fue mayor en aguas intermedias y presentó cambios fuertes entre épocas de muestreo y entre ecosistemas. En aguas superficiales se presentó fotoinhibición, la cual fue más fuerte en Guatavita. La eficiencia fotosintética fue menor en el lago andino debido posiblemente a diferencias climáticas, de altura sobre el nivel del mar y de estratificación. Durante los ensayos de laboratorio se observó que la eficiencia disminuyó con el tiempo, lo cual pudo deberse a una aclimatación de las algas a la oscuridad. Los datos de laboratorio confirmaron que el fitoplancton epilimnético del lago Guatavita estuvo fotoinhibido en la época de estratificación.Commonly relation between variable fluorescence and maximum fluorescence (Fv/Fm of the algae community has been utilized like a measure of the phytoplanktonic photosynthetic efficiency.

Recentemente, ad esempio, la provincia è stata una delle dimensioni centrali nei commenti sul voto in Gran Bretagna per la ‘Brexit’ e nelle analisi sull’ascesa di Donald Trump negli Stati Uniti. In entrambi i casi, infatti, è invocata una più adeguata comprensione dei territori di provincia di cui tali fenomeni sarebbero espressione.

    2016-08-01

    This cross-sectional study was undertaken to determine the prevalence of asymptomatic bacteriuria (ASB), the commonest bacterial isolates and the antibiotic sensitivity pattern among 556 pregnant women in Lagos University Teaching Hospital (LUTH), Nigeria. Women with a bacterial count over 100,000 colony-forming units per millilitre of the same organisms in paired urine samples were considered to have ASB. The prevalence of ASB was 14.6%. Klebsiella was the commonest micro-organism (39.2%) isolated. ASB was significantly associated with marital status, body mass index and parity. There was a significant relationship between urinary nitrites and ASB. The isolated organisms showed remarkable resistance to commonly prescribed antibiotics such as amoxicillin, cloxacillin and trimethoprim but good sensitivity to ofloxacin, gentamycin and ceftazidime. These facts have implications for the management of ASB in pregnancy.

Other symptoms include otalgia, headache, neck pain and trismus. To determine the pattern of Temporomandibular joint pain dysfunction syndrome patients managed at the Lagos University Teaching Hospital, Lagos, Nigeria. A descriptive study of patients with signs and symptoms of Temporomandibular joint pain dysfunction syndrome attending the Oral Medicine Clinic of Lagos University Teaching Hospital. Twenty-one patients with Temporomandibular joint pain dysfunction syndrome were enrolled into the study, out of which 10(48%) were females and 11(52%) were males. The age range was 23-81years with a mean of 45.2 ± 18.9 years. Majority of the patients 20(95.2%) complained of pain around the joint, in the pre-auricular region, in the muscles of mastication and the ear. While 7(35%) complained of clicking sounds, 10(47.6%) complained of pain on mouth opening and during mastication only. In all 5(23.8%) had impaired movement of the jaws, mouth opening was normal in 18(85.7%) but reduced in 3(14.3%) patients. Over half of patients 12(57%) experienced clicking sounds, there was tenderness around the temporomandibular joint in 16(76.2%) cases, pain in the ear of 7(33.3%) patients and 13(61.9%) people presented with tenderness of the muscles of mastication. Conservative management of all the cases resulted in resolution of the symptoms. Temporomandibular joint pain dysfunction syndrome has diverse clinical presentation and though distressing, it responds to prompt and effective conservative management.

    Use of ionising radiation in diagnostic radiography could lead to hazards such as somatic and genetic damages. Compliance to safe work and radiation protection practices could mitigate such risks. The aim of the study was to assess the knowledge and radiation protection practices among radiographers in Lagos, Nigeria. The study was a prospective cross sectional survey. Convenience sampling technique was used to select four x-ray diagnostic centres in four tertiary hospitals in Lagos metropolis. Data were analysed with Epi- info software, version 3.5.1. Average score on assessment of knowledge was 73%. Most modern radiation protection instruments were lacking in all the centres studied. Application of shielding devices such as gonad shield for protection was neglected mostly in government hospitals. Most x-ray machines were quite old and evidence of quality assurance tests performed on such machines were lacking. Radiographers within Lagos metropolis showed an excellent knowledge of radiation protection within the study period. Adherence to radiation protection practices among radiographers in Lagos metropolis during the period studied was, however, poor. Radiographers in Lagos, Nigeria should embrace current trends in radiation protection and make more concerted efforts to apply their knowledge in protecting themselves and patients from harmful effects of ionising radiation.

Se realizó un estudio descriptivo retrospectivo de la totalidad de los pacientes afectados por leptospirosis en el año 1998 en la provincia de Cienfuegos. Los datos primarios se obtuvieron del registro del Centro Provincial de Higiene y Epidemiología (CPHE procediéndose a la aplicación de encuesta para obtener datos de interés como: sexo, edad, municipio de residencia, ocupación, fuente de infección, vacunación previa, evolución, necesidad de ingreso, y seguimiento por el Médico de la Familia, teniendo como objetivo determinar el comportamiento de la entidad en el período estudiado y el rol del Médico de la Familia. Los datos fueron procesados por sistema EXCEL de Windows y los principales resultados se exponen en figuras diseñadas por Power Point. Se constató la disminución de la morbilidad por esta afección en la provincia respecto al año 1997 en 33,3 %, la letalidad fue de 0 y existió un predominio del sexo masculino con 40 casos, y del grupo etáreo de 25 a 44 años con el 70 %. La mayor incidencia correspondió al municipio Palmira. Ninguno de los enfermos había sido inmunizado con la vacuna cubana antileptospírica. Los ingresos domiciliarios se realizaron en el 77 % de los casos con evolución favorable, demostrándose la efectividad en la atención a nivel primario y el papel del Médico de la Familia tanto en la labor preventiva como curativa. La seroconversión y el aumento del título fueron las principales pruebas de confirmación de 45 y 41 % respectivamente, aún existen índices de roedores no despreciables en el territorio provincial.

    Introduction Injuries are the third most important cause of overall deaths globally with one-quarter resulting from road traffic crashes. Majority of these deaths occur before arrival in the hospital and can be reduced with prompt and efficient prehospital care. The aim of this study was to highlight the burden of road traffic injury (RTI) in Lagos, Nigeria and assess the effectiveness of prehospital care, especially the role of Lagos State Ambulance Service (LASAMBUS) in providing initial care and transportation of the injured to the hospital. A three-year, retrospective review of road traffic injured patients seen at the Surgical Emergency Room (SER) of the Lagos State University Teaching Hospital (LASUTH), Ikeja, Nigeria, from January 1, 2012 to December 31, 2014 was conducted. Parameters extracted from the Institution Trauma Registry included bio-data, date and time of injury, date and time of arrival in SER, host status, type of vehicle involved, and region(s) injured. Information on how patients came to the hospital and outcome in SER also were recorded. Results were analyzed using Statistical Package for Social Sciences (SPSS; IBM Corporation; Armonk, New York USA) version 16. A total of 23,537 patients were seen during the study period. Among them, 16,024 (68.1%) had trauma. Road traffic crashes were responsible in 5,629 (35.0%) of trauma cases. Passengers constituted 42.0% of the injured, followed by pedestrians (34.0%). Four wheelers were the most frequent vehicle type involved (54.0%), followed by motor cycles (30.0%). Regions mainly affected were head and neck (40.0%) and lower limb (29.0%). Less than one-quarter (24.0%) presented to the emergency room within an hour, while one-third arrived between one and six hours following injury. Relatives brought 55.4%, followed by bystanders (21.4%). Only 2.3% had formal prehospital care and were brought to the hospital by LASAMBUS. They also had significantly shorter arrival time.

El Chaltén y El Calafate son los asentamientos que desarrollan el turismo como base de su economía. El incremento de la actividad se debe a los cambios en el sistema productivo provincial en las últimas décadas, netamente ganadero en El Calafate a principios y mediados del siglo XX. Asimismo, las razones geopolíticas que dieron origen a El Chaltén, hoy han pasado a ser parte de su historia, ya que el turismo es la principal actividad que desarrolla el asentamiento. Esta actividad en la provincia se ha incrementado a partir de la década del 1990 impulsada por los Estados nacional, provincial y municipal que llevan adelante políticas de promoción en el sector. Por otra parte, en estos asentamientos, el auge turístico trae aparejado consecuencias sociales y ambientales dado el crecimiento acelerado de los mismos en cuanto a la población que se radica, la falta de infraestructura básica y equipamiento son los principales sin dejar de mencionar la especulación inmobiliaria. El objetivo del presente trabajo es analizar las transformaciones espaciales en los asentamientos del oeste de la provincia de Santa Cruz particularmente los del departamento Lago Argentino a partir del incremento de la actividad turística en el área en las últimas décadas.

    Lago La Plata dam is located between the municipalities of Naranjito and Toa Alta in north central Puerto Rico, about 5 kilometers south of the town of Toa Alta and about 5 kilometers north of the town of Naranjito. The reservoir impounds the waters of the Rio de La Plata, the Rio Guadiana, and the Rio Ca?as, and is part of the San Juan Metropolitan Water District, which provides about 35 percent of the total water demand for the area (Soler-Lopez and others, 2000). The reservoir has a drainage area of about 469 square kilometers. The dam was constructed in 1974 and is a concrete gravity structure with a normal pool elevation of 52.00 meters above mean sea level (Puerto Rico Electric Power Authority, 1979). During October 1998, the U.S. Geological Survey (USGS), Caribbean Water Science Center, in cooperation with the Puerto Rico Aqueduct and Sewer Authority (PRASA) conducted a bathymetric survey of Lago La Plata to assess the impact of Hurricane Georges on the storage capacity of the reservoir. Between July 17 and 20, 2006, the USGS and the PRASA conducted an additional bathymetric survey of Lago La Plata to update the reservoir storage capacity and determine the reservoir sedimentation rate by comparing the 2006 survey data with the 1998 survey data.. The purpose of this report is to update the reservoir storage capacity, sedimentation rates, and areas of substantial sediment accumulation since 1998.

    Full Text Available Siendo la producción epigráfica el reflejo de la actividad publicitaria de una determianda sociedad, ésta presenta especiales caracterísiticas a lo largo del siglo XII en la actual provincia de Burgos. Desde finales del siglo XI y hasta los inicios del siglo XIII, en la actual provincia de Burgos se introdujo una nueva forma de escritura publicitaria procedente del mundo franco, cuyo origen gráfico estaba en la escritura monumental romana. Esta nueva escritura convivió en nuestra provincia junto con la visigótica nacional hasta que ésta última fue progresivamente desapareciendo a lo largo del siglo XII. Así pues, aquí presentamos un estudio de esta escritura basado en los sesenta y ocho epígrafes que forman el Corpus de inscripciones carolinas de la provincia de Burgos. En él mostramos el proceso evolutivo de la escritura carolina, la convivencia de estas escrituras, así como las particularidades asociadas a los diferentes centros de producción.Epigraphical production is a reflection of the activity of publicity in a given society. This production presents a number of special features as in the case of the area covering the current province of Burgos during the twelfth century. From the end of the eleventh to the beginning of the twelfth century, a new form of script originating in Roman monumental inscriptions was introduced through the Frankish realms in the territory known today as Burgos. This new type of writing was being produced simultaneously with the national Visigothic script until the latter gradually vanish edduring the twelfth century. Our study examines this type of script based on seventy-eight epigraphs that make up the complete body of Carolingian inscriptions in Burgos. It will thus show the evolutionary process of the Carolingian script, the coexistence of these two types of writing and the main features associated with the different centres of production.

    2008-07-01

    Lagos bat virus (LBV) belongs to genotype 2 of the Lyssavirus genus. The complete nucleoprotein (N), phosphoprotein (P), matrixprotein (M) and glycoprotein (G) genes of 13 LBV isolates were sequenced and phylogenetically compared with other lyssavirus representatives. The results identified three different lineages of LBV. One of these lineages demonstrated sufficient sequence diversity to be considered a new lyssavirus genotype (Dakar bat lyssavirus). The suggested quantitative separation of lyssavirus genotypes using the N, P, M and G genes was also investigated using P-distances matrixes. Results indicated that the current criteria should be revised since overlaps between intergenotypic and intragenotypic variation occur.

Da gennaio a settembre 2008 sono stati esaminati 178 cani, 56 carcasse e 122 campioni di feci. Nelle carcasse sono stati ricercati i parassiti adulti nel ventricolo destro e nell’arteria polmonare e le forme larvali in tessuti di organi interni e cervello. Nelle feci è stata ricercata la forma larvale L1 con tre metodiche diagnostiche utilizzate correntemente per la ricerca di endoparassiti e larve di strongili broncopolmonari. Sono stati diagnosticati 20 casi (8,9% con identificazione di parassiti adulti in 5 cani e larve L1 in altri 15 soggetti. L’esame anatomopatologico delle carcasse dei cani con nematodi adulti ha evidenziato polmonite, pleurite, schiuma rossastra in trachea, versamento di liquido sieroemorragico in cavità toracica e ingrossamento di linfonodi medinici e meseraici. L’esame istologico dei tessuti ha evidenziato quadri gravi e sovrapponibili con lesioni da localizzazione dei parassiti in reni, linfonodi e cervello. Il numero cospicuo di casi riscontrati ha reso indispensabile considerare l’angiostrongilosi nelle diagnosi differenziali degli esami clinici e autoptici di cani della provincia di Chieti (Italia e dei territori confinanti.

This study was carried out to assess body iron stores in regular blood donors. Methods: A total of 52 regular (study and 30 first-time (control volunteer blood donors were studied prospectively. Twenty milliliters of venous blood was drawn from each subject, 5 mL of which was put into sodium ethylenediamine tetra-acetic acid specimen bottles for a full blood count, including red blood cell indices. The remaining sample was allowed to clot in a plain container, and the serum was then retrieved for serum ferritin, serum iron, and serum transferrin receptor measurement by enzyme-linked immunosorbent assay. Results: Mean hemoglobin and packed cell volume in the study group (13.47 ± 2.36 g/dL and 42.00 ± 7.10, respectively, P = 0.303 were not significantly higher than in the control group (12.98 ± 1.30 g/dL and 39.76 ± 4.41, respectively, P = 0.119.

    A survey of healthcare waste management practices and their implications for health and the environment was carried out. The study assessed waste management practices in 20 healthcare facilities ranging in capacity from 40 to 600 beds in Ikorodu and metropolitan Lagos, Lagos State, Nigeria. The prevailing healthcare waste management status was analysed. Management issues on quantities and proportion of different constituents of waste, segregation, collection, handling, transportation, treatment and disposal methods were assessed. The waste generation averaged 0.631 kg bed(-1) day(-1) over the survey area. The waste stream from the healthcare facilities consisted of general waste (59.0%), infectious waste (29.7%), sharps and pathological (8.9%), chemical (1.45%) and others (0.95%). Sharps/pathological waste includes disposable syringes. In general, the waste materials were collected in a mixed form, transported and disposed of along with municipal solid waste with attendant risks to health and safety. Most facilities lacked appropriate treatment systems for a variety of reasons that included inadequate funding and little or no priority for healthcare waste management as well as a lack of professionally competent waste managers among healthcare providers. Hazards associated with healthcare waste management and shortcomings in the existing system were identified.

    Full Text Available Frente al desafío que la rabia representa para la industria pecuaria y la salud pública en América Latina, el presente artículo tiene como objetivo hacer una revisión de literatura amplia y crítica sobre la epidemiología de la rabia transmitida por murciélagos en Brasil. El tema es abordado inicialmente desde una perspectiva histórica hasta la caracterización molecular de aislamientos del virus, para finalmente contrastar con la situación de otros países de las Américas. La información referente a Brasil es presentada de manera separada debido a la gran abundancia de especies de murciélagos de diversos hábitos alimenticios, implicadas en la transmisión del virus de la rabia y las complejas relaciones entre los ciclos epidemiológicos revelados por estudios de tipificación antigénica y análisis filogenético, lo  cual ha permitido reconocer con más nitidez, la importancia de los quirópteros como reservorios y transmisores de esta enfermedad.  Este nuevo escenario epidemiológico exige reexaminar las medidas de control aplicadas hasta el momento, desde un abordaje multidisciplinar, así como cooperación intersectorial y participación por parte de la comunidad.

    Full Text Available Los grandes lagos de Nicaragua, son comparables con el sistema de grandes lagos africanos. Contienen una gran diversidad de peces, incluyendo varios peces endémicos de la familia Cichlidae. La captura de peces en el Lago de Cocibolca, estandarizada en 100 metros de red, promedió 4.34 kilogramos en el área de Ometepe, en donde la tilapia constituyó el 1.5 % del peso total de la captura. Este promedio fue de 0.80 kilogramos en la costa septentrional, donde la tilapia constituyó 54% del peso total de la captura. Un estudio ruso efectuado en 1983 y desarrollado en todo el Lago, demostró que el promedio era de 4.66 kilogramos. Los autores del presente artículo recomiendan que en el Lago Cocibolca se implemente un plan de manejo adecuado para controlar la población de tilapia y rescatar un ecosistema en peligro de colapso

    1994-01-01

    Full Text Available Se propone una aproximación al cambio continuo y acelerado propio del crecimiento demográfico secular en las medianas capitales de provincias. Asumiendo el análisis del caso de la ciudad de Lugo como paradigma, se reconoce el efecto mediador de la definición de la situación, del ideal urbano y la identidad colectivamente asumida y defendida. Es evidente la magnitud del cambio social que se produce en todos los ámbitos de la vida urbana de Lugo, pero este se vive sin rupturas importantes, sin la confrontación abierta de interés. Por el contrario, se observa una especie de acomodación pasiva en función de una definición provinciana de la ciudad que niega el cambio y defiende la continuidad de una identidad comunitaria. Los efectos del ideal urbano lucense así definido se hacen sentir especialmente en relación al comportamiento social público, a las distintas posibilidades de integración a la ciudad de los inmigrantes de origen rural y urbano y en relacion al grado y modo de asimilación del cambio.

    Full Text Available Estate marketing is an aspect of the profession of Estate Surveying and Valuation in Nigeria. Previous studies on estate marketing identified that there are challenges affecting estate marketing and the resultant effect on these challenges affects the credibility of the profession of Estate Surveying and Valuation in Nigeria. This necessitates the need to examine the practice of estate marketing in Nigeria. This study examined estate marketing practice among estate surveyors and valuers in Ikeja, Lagos Nigeria. The sample size for the study is the 64 registered Estate Surveying and Valuation firms in the study area. Data gathered were analyzed using descriptive statistics and 5-point likert ordinal scale. Findings from the study revealed that the use of brochure or bulletin is the most common estate marketing method in the study area. Also, it was revealed from the study that the use of press is the most cost effective method of estate marketing in the study area. The study identified the various challenges of estate marketing. However, collection of double professional fees is the most prevalent challenge of estate marketing in the study area. Finally, aggressive marketing which leads to unethical practices is the most prevalent mitigating measures adopted by Estate Surveyors and Valuers in the study area. Recommendations were made on how to review the ethical regulations guiding the practice of Estate Surveying and Valuation which will consequently improve marketing in the study area.

    Congenital club foot has been sparsely reported in literature in Nigeria, although it has been reported as the commonest congenital musculoskeletal abnormality. This study enumerates the point prevalence of this disease in a university teaching hospital in Lagos. Better understanding of the epidemiology in our community should improve awareness, and influence management. Between June 2005 and July 2006, 72 consecutive patients with congenital club feet were seen in the orthopaedic clinic of our Hospital. Demographic data, birth weight, family history, birth facility, maternal age and associated congenital anomalies were recorded and analysed using Statistical Programme for Social Sciences (SPSS) version 15. A total of 72 patients were seen, 28 of whom had bilateral club feet resulting in a total of 100 feet. There were 38 males and 34 females. Only 29% presented in the first month of life and 28% in the second month. Maternal ages ranged between 19 and 38 years and no family history of congenital club foot was given,. Babies delivered outside the orthodox medical system (churches, traditional healers, home etc) constituted 28%. The commonest associated congenital anomalies were tibia hemimelia, hydrocephalus, inguinal hernia and umbilical hernia. A default rate of 28% was observed during treatment. Congenital club foot may not be uncommon in Nigeria. Late presentation and high default rate before correction of the deformity were observed. Establishment of special club foot clinics should reduce the default rate. Training of healthcare workers in maternity units as well as Public awareness should encourage early referral to specialists.

Al inicio de la década de 1980 se construyó una represa en el río de desagüe y el caudal de salida fue desviado hacia el Embalse Arenal. Se realizó un primer estudio entre 1990 y 1991, y luego en el año 2001 antes de que se construyera una nueva modificación del lago mediante el levantamiento del nivel de la presa en un metro con el fin de utilizar la descarga para la producción de energía hidroeléctrica. Del 2002 al 2010 se realizó un monitoreo limnológico dos veces al año. Aquí se presenta un análisis de las principales características y de los cambios a través del tiempo. El lago es polimíctico discontinuo y desarrolla una termoclina intermitente a 6m de profundidad, la cual puede perdurar por varios días o semanas a juzgar por el desarrollo de una capa anóxica cercana al fondo. Desde su modificación la temperatura superficial del lago ha alcanzado valores mayores a los reportados con anterioridad. El hipolimnion muestra periodos de hipoxia a anoxia que se han vuelto más frecuentes. A pesar de la turbidez del lago, la concentración de nutrientes y de clorofila a son bajos. La tendencia en tiempos recientes es a una reducción de la clorofila a y un aumento en la trasparencia del agua. Estos cambios son similares a los observados en lagos donde se ha logrado atribuirlos al cambio climático global. También se pueden deber a la modificación del flujo del efluente por la operación intermitente de la planta hidroeléctrica, que favorece la acumulación de calor en la columna de agua. Esto debido a que otros factores, como el cambio en el uso del suelo en los alrededores del lago ocurrieron en la década de 1980, por lo que no se les puede atribuir una influencia en los cambios observados en los últimos 10 años.

    The U.S. Geological Survey (USGS) is monitoring and analyzing glacial-lake outburst floods (GLOFs) in the Colonia valley in the Patagonia region of southern Chile. A GLOF is a type of flood that occurs when water impounded by a glacier or a glacial moraine is released catastrophically. In the Colonia valley, GLOFs originating from Lago Cachet Dos, which is dammed by the Colonia Glacier, have recurred periodically since 2008. The water discharged during these GLOFs flows under or through the Colonia Glacier, into Lago Colonia and then the Río Colonia, and finally into the Río Baker—Chile's largest river in terms of volume of water.

    Full Text Available Background: Fixed drug eruption (FDE is common cutaneous drug eruption characterized by the development of one or more annular, oval, erythematous, and hyperpigmented patches as a result of systemic exposure to a drug. Drugs causing FDE vary with prevailing diseases and prescription pattern in different parts of the world. This study is aimed at reviewing cases of FDE seen at the dermatology outpatient clinic of Lagos University Teaching Hospital (LUTH over a 9-year period, highlighting the spectrum of drugs implicated and the clinical characteristics. Materials and Methods: Data were obtained from the clinic records and patients' case notes. These included the demographic details, duration of presentation, drugs implicated, and clinical characteristics. Results: FDE was diagnosed in 1.8% (295/16,160 of patients seen. There was a slight female preponderance. Antimalarials were the commonest group of medications implicated (51.0% followed by antibiotics (27.9%; analgesics (10.2%, herbal toothpaste (6.1%, and oral hypoglycemic agents (4.1%. Sulfonamides were the commonest group of drugs found in 78 patients (53.1% predominantly as sulfadoxine/pyrimethamine antimalarials and trimethoprim/sulfamethoxazole antibiotics (co-trimoxazole. Conclusion: Concerted efforts are needed to discourage over-the-counter sales and purchase of nonprescription sulfonamide-based medications. A change in prescription pattern from sulfonamides to other classes of antimalarials and antibiotics is desirable and/or recommended. Patients should inform their caregivers at any point of care about their reaction to drugs. It is advised that they have a list of common implicating drugs and they wear a medic alert or carry an ID card bearing this information.

    2011-01-01

    Background Over three-quarter of the world's population is using herbal medicines with an increasing trend globally. Herbal medicines may be beneficial but are not completely harmless. This study aimed to assess the extent of use and the general knowledge of the benefits and safety of herbal medicines among urban residents in Lagos, Nigeria. Methods The study involved 388 participants recruited by cluster and random sampling techniques. Participants were interviewed with a structured open- and close-ended questionnaire. The information obtained comprises the demography and types of herbal medicines used by the respondents; indications for their use; the sources, benefits and adverse effects of the herbal medicines they used. Results A total of 12 herbal medicines (crude or refined) were used by the respondents, either alone or in combination with other herbal medicines. Herbal medicines were reportedly used by 259 (66.8%) respondents. 'Agbo jedi-jedi' (35%) was the most frequently used herbal medicine preparation, followed by 'agbo-iba' (27.5%) and Oroki herbal mixture® (9%). Family and friends had a marked influence on 78.4% of the respondents who used herbal medicine preparations. Herbal medicines were considered safe by half of the respondents despite 20.8% of those who experienced mild to moderate adverse effects. Conclusions Herbal medicine is popular among the respondents but they appear to be ignorant of its potential toxicities. It may be necessary to evaluate the safety, efficacy and quality of herbal medicines and their products through randomised clinical trial studies. Public enlightenment programme about safe use of herbal medicines may be necessary as a means of minimizing the potential adverse effects. PMID:22117933

    Full Text Available Abstract Background Infantile colic is a self-limiting condition that is distributed worldwide. It is often misdiagnosed as an organic disease for which an infant is admitted to the hospital. Many studies have described the aetiopathogenesis, pharmacologic and non-pharmacologic management of colic but none has evaluated self-medication for infants with colic. The aim of this study was therefore to determine the knowledge of Nigerian mothers about colic, their home-based management, extent of self-medication for the infants with colic and the types of medicines involved. Methods It is a prospective study conducted at the vaccination clinics of 20 primary health care centres, each from different Local Government Areas in Lagos, Nigeria. Eight hundred mothers that brought their infants for vaccination between April and September, 2006 were interviewed with open-and close-ended questionnaire. Results Six hundred and eighty three (85.4% mothers claimed they had a good knowledge of colic. Incessant and excessive cry was the main clinical feature of colic identified by 430(62.9% mothers. Three hundred and seventy eight (67.7% infants were treated by self-medication, 157 (28.1% sought medical intervention and 17 (3.1% were treated at a traditional birth attendant home. Herbal medicines constituted 51.8% of the self-medicated medicines, of which 48 (26.2% were "Ororo Ogiri". Nospamin® (49.5% and Gripe water® (43.0% were the two frequently prescribed and self-medicated medicines for infants with colic. Conclusion Nigerian mothers are deficient in their knowledge of colic. Self-medication was the most frequently used home-based intervention. Health education would appear necessary to improve parental management of this self-limiting condition.

    Lagos, a major urban agglomeration in the world is characterized by wetlands and basin for upstream rivers such as Ogun, Oshun and Yewa Rivers. Ongoing environmental pressures exerted by large-scale land reclamation for residential quarters, refuse and sewage dumping, and other uses, however, are suspected to have had a substantial impact on ecological health of the Lagos wetland ecosystems over the last few decades. To determine the impact of these pressures, we examined spatial changes in three wetlands areas- Badore/Langbasa (BL), Festac/Iba/Ijegun (FI) and Ologe/Otto-Awori (OO) through field sample collection and analyses of surface water, sediments, air-water interface gas fluxes and vegetations. Surface water conductivity, total suspended solids (TSS), alkalinity, chloride, biological oxygen demand (BOD), nitrate, phosphate and heavy metals (Zn, Cu, Fe, Na, Mn, Pb, Cd, K and Ni) exhibited relative spatial stability while other water quality parameters varied significantly (P International Union for Conservation of Nature (IUCN). There are indications of steady rise in greenhouse gas levels in Lagos since air CO2 value at BL have reached global threshold of 400 ppm with OO and FI closely approaching. We conclude that the Lagos wetland ecosystems, especially OO and FI still have some semblance of natural habitat. However, further destruction and unwise use of the resources could cause damage to physical, chemical, geological and biological processes in nature, which could result to grave socio-economic and cultural consequences to the local communities whose livelihood and lifestyle depend on these valued wetlands.

    To investigate the prevalence of maternal selenium deficiency and its effects on pregnancy outcomes in pregnant women with HIV in Lagos, Nigeria. The present descriptive cross-sectional study enrolled women aged 15-49 years with HIV who were at 14-26 weeks of a singleton pregnancy and were attending Lagos University Teaching Hospital, Lagos, Nigeria, between August 1, 2016, and April 30, 2017. Participants were selected by consecutive sampling and baseline data were collected through interviews. Venous blood samples were obtained to measure selenium concentrations, and associations between low maternal selenium concentrations (defined as <0.89 μmol/L) and pregnancy outcomes were examined using bivariate and multivariate analysis. The final analysis included 113 patients; selenium deficiency was recorded in 23 (20.4%) patients. Women with selenium deficiency had an approximately eight-fold higher risk of preterm delivery (adjusted odds ratio 7.61, 95% confidence interval 4.37-18.89; P=0.031) and of delivering a term neonate with a low delivery weight (adjusted odds ratio 8.11, 95% confidence interval 3.27-17.22; P=0.012), compared with women with a normal selenium concentration. The prevalence of selenium deficiency among pregnant women with HIV in Lagos was relatively high. The significant associations observed between maternal selenium deficiency and adverse pregnancy outcomes could have implications for the future management of HIV in pregnancy. © 2018 International Federation of Gynecology and Obstetrics.

  14. Within salvation: girl hawkers and the colonial state in development era Lagos.

    George, Abosede

    2011-01-01

    For almost two decades between the close of the Second World War and Nigerian independence in 1960, the British colonial state which faced a crisis of legitimacy in Lagos upheld city ordinances that made itinerant trading by young children in Lagos a punishable status offense. Although anti-trading regulations were gender-neutral in their language, girls were disproportionately sanctioned for engaging in street trading and related activities. In defending their concentration on girl sellers over boy sellers, colonial welfare officials painted a picture of the urban context as an inherently dangerous context and of girls as being particularly at risk of violent assault in the city, making them particularly in need of protection from town life. Sources which show that parents generally resisted or ignored the street trading regulations and continued permitting their daughters to sell despite entreaties, warnings, or fines from colonial officials, suggest that African parents and British colonial officials may have had conflicting views on the inherent danger of the city, on what constituted child endangerment, and on the gendered nature of childhood. This article argues that the girl saving campaigns of development era Lagos were as much about the legitimization of a colonial state facing a crisis of legitimacy as they were about debates between African parents and colonial welfare officials in Lagos concerning ideas of children and childhood and the dangers of street trading by African girls.

    Full Text Available The clinicopathological and endoscopic features of dyspepsia have not been well studied in Nigeria due to the high cost of gastroscopes and lack of the relevant expertise. This study was designed to highlight these features and possible risk factors. This prospective study was conducted on adult dyspeptic patients who fulfilled the study criteria from November 2007 to December 2008 at a University hospital in Lagos, Nigeria. Demographic and clinical presentation including possible risk factors were obtained through a questionnaire administered by an interviewer followed by an upper gastrointestinal endoscopy and gastric biopsy. Of the 123 subjects who took part in the study, 100 gave their consent to an upper gastrointestinal endoscopy and biopsy. The male:female ratio was 1:1, mean age was 44.98 (SD 15.4 years and the modal age group was 38-47years. The prevalence of dyspepsia was 29% and epigastric pain was the most common presentation. Endoscopic findings were superficial mucosal lesion (21%, peptic ulcer (16%, features of gastroesophageal reflux disease (10%, and gastric cancer (2%, as well normal findings (44%. Non-steroidal antiinflammatory drug (NSAID use as a risk factor had a significant association with positive endoscopic findings; relative risk for development of positive endoscopic findings was 1.5% (P =0.03. Histology showed rates of chronic gastritis to be 91% and normal values 9%. The most common type of gastritis was the non-specific form (59.3%, followed by H. Pylori-associated gastritis (36.3%. The topography of gastritis was mainly pangastritis (68.1% and antral predominant in 23.1%. The prevalence of H. pylori by histology was 41%. The presence of H. pylori was not associated with severity, location or duration of symptoms.

    The upsurge in the reported cases of diverticular disease (DD) has led to a re-appraisal of the earlier held views that it was a rare entity in Nigeria. The advent of colonoscopy has contributed in no small way to this change. We sought to determine the clinical characteristics, indications for colonoscopy, and intra-procedural findings among these patients. A retrospective cross-sectional study was carried out on the colonoscopy records from four private endoscopy units based in Lagos State, Nigeria. The records were drawn from a 5-year period (August 2010 to July 2015). The endoscopy logs and reports were reviewed, and the bio data, indications, and colonoscopy findings were gleaned. A total of 265 colonoscopies were carried out in the stated period. Of these, 28 (10.6%) had DD. Of the patients with DD, 5 (17.9%) were females while 23 (82.1%) were males. Their ages ranged from 46 to 94 years (mean = 68.2 ± 11 years). Fifteen patients had been referred for the procedure on account of hematochezia alone (15 = 53.6%). Other reasons for referral included abdominal pain alone (2 = 7%), hematochezia plus abdominal pain (5 = 17.9%), and change in bowel habits (3 = 10.8%). Ten (35%) patients had pan-colonic involvement. Regional disease involved the right side alone in only one case (3.5%) while the other combinations of sites are as follows; 6 (21.4%) in the sigmoid colon alone, 2 (7%) in the descending colon alone, 5 (17.9%) in the sigmoid-descending colon, 4 (14.3%) in the sigmoid-descending-transverse colon, thus the sigmoid colon was involved in 25 (89.3%) cases. Five cases (17.9%) had endoscopic features suggestive of diverticulitis. DD should no longer be regarded as a rare problem in the Nigerian patient. The study findings support the notion of higher prevalence among the elderly, in males, and of sigmoid colon involvement.

    Full Text Available Background and Objective: According to the World Health Organization, the number of obese children would increase to 70 million by 2025 if no intervention is made. An increase in the prevalence of overweight and obesity among school children in Lagos State, Nigeria has been established, but specific factors promoting its prevalence are unknown. The aim of this study was to elicit the views of stakeholders on the perceived causes for the rise in child overweight and obesity. Methods: Five focus group discussions were conducted with different groups of stakeholders involved in child care, namely: Parents, teachers, and healthcare givers. Participants were recruited using a purposive sampling method; a structured question guide was employed for the discussion sessions. The discussions were recorded, collated, and analyzed using grounded theory to extract themes. Results: Six themes emerged as factors responsible for the rise, of which civilization and lifestyle imbalance of the populace emerged as the prominent cause. Of the fifty respondents, 76% of respondents identified parents (particularly young mothers as major contributors to the prevalence of overweight and obesity in children of Lagos State; and 52.3% of the participants reported that a direct relationship exists between income class of parent and weight of a child resident in Lagos. Conclusion: Civilization and lifestyle imbalance, insecurity and congestion, low level of public awareness, inadequate educative and enlightenment programs, myths and societal perception were factors identified to responsible for the rise in the prevalence of child obesity in Lagos, Nigeria. Preventive strategies to control the prevalence of overweight and obesity in children residing in Lagos State should be considered for further studies.

  5. The realities of Lagos urban development vision on livelihoods of the urban poor

    Full Text Available Similar to many other cities in sub-Saharan African countries, the struggle between urban development policies and the livelihoods of the urban poor is one of the urban development challenges facing Lagos. This paper examines the realities of the Lagos urban development policies and intiatives on the livelihoods of the urban poor. The state government embarked on series of what it calls sustainable urban transformation policies towards making Lagos ‘an African model megacity’ and a global economic and financial hub that is safe, secure, functional and productive, with a view to achieving poverty alleviation and sustainable development. This paper, through the lens of theoretical and analytical underpinnings of Sustainable Livelihoods Framework, however, argues that the actions of the state government contradict the whole essence of sustainable urban development and poverty alleviation, but reflect an agenda deliberately targeted to further impoverish the poor. While the Sustainable Livelihood was used as the theoretical and analytical framework, this paper essentially focuses on the Policies, Institutions and Processes component of the framework. This provides a unique entry point for understanding the implications of the Lagos urban development aspirations on the livelihoods of the urban poor. The research uses mixed methods research design with a broad range of data-collection methods, including household surveys, interviews, direct observation and photography, documentary review and policy document analysis. The study reveals that there is a disconnection between urban development policies and realities of the poor. The implementation of urban development projects and policies works against the urban poor and resulted in more hardship, through reduction in livelihood opportunities or complete loss of livelihoods. This study, therefore, suggests that one important element in reducing poverty in Lagos’ informal settlements is a policy

    Reconciling orbital-scale patterns of inter-hemispheric South American climate during the Quaternary requires continuous, high-resolution paleoclimate records that span multiple glacial cycles from both hemispheres. Southern Andean Quaternary climates are represented by multi-proxy results from Lake Titicaca (Peru-Bolivia) spanning the last 400 ka and by pending results from the Lago Junin Drilling Project (Peru). Although Northern Andean sediment records spanning the last few million years have been retrieved from the Bogota and Fúquene Basins in the Eastern Cordillera of the Colombian Andes, climatic reconstructions based on these cores have thus far been limited to pollen-based investigations. When viewed together with the Southern Hemisphere results, these records suggest an anti-phased hemispheric climatic response during glacial cycles. In order to better assess orbital-scale climate responses, however, independent temperature and hydroclimate proxies from the Northern Hemisphere are needed in addition to vegetation histories. As part of this objective, an effort is underway to develop a paleoclimate record from Lago de Tota (3030 m asl), the largest lake in Colombia and the third largest lake in the Andes. One of 17 highland tectonic basins in Eastern Cordillera, Lago de Tota formed during Tertiary uplift that deformed pre-foreland megasequences, synrift and back-arc megasequences. The precise age and thickness of sediments in the Lago de Tota basin has not previously been established. Here, we present results from a recent single-channel seismic reflection survey collected with a small (5 cubic inch) air gun and high-resolution CHIRP sub-bottom data. With these data, we examine the depositional history and sequence stratigraphy of Lago de Tota and assess its potential as a deep drilling target.

    Lago Cerrillos dam, located in the municipality of Ponce in southern Puerto Rico, was constructed in 1991 as part of the multipurpose Rio Portugues and Bucana Project. This project provides flood protection, water supply, and recreation facilities for the municipio of Ponce. The reservoir had an original storage capacity of 38.03 million cubic meters at maximum conservation pool elevation of 174.65 meters above mean sea level and a drainage area of 45.32 square kilometers. Sedimentation in Lago Cerrillos reservoir has reduced the storage capacity from 38.03 million cubic meters in 1991 to 37.26 million cubic meters in 2008, which represents a total storage loss of about 2 percent. During July 29 to August 23, 2002, 8,492 cubic meters of sediment were removed from the Rio Cerrillos mouth of the reservoir. Taking into account this removed material, the total water-storage loss as of 2008 is 778,492 cubic meters, and the long-term annual water-storage capacity loss rate is about 45,794 cubic meters per year or about 0.12 percent per year. The Lago Cerrillos net sediment-contributing drainage area has an average sediment yield of about 1,069 cubic meters per square kilometer per year. Sediment accumulation in Lago Cerrillos is not uniformly distributed and averages about 3 meters in thickness. This represents a sediment deposition rate of about 18 centimeters per year. On the basis of the 2008 reservoir storage capacity of 37.26 million cubic meters per year and a long-term sedimentation rate of 45,794 cubic meters per year, Lago Cerrillos is estimated to have a useful life of about 814 years or until the year 2822.

HPV is preventable with the use of HPV vaccines. Objectives: The objective of this study was to assess mothers' HPV knowledge and their willingness to vaccinate their adolescent daughters in Lagos, Nigeria. Materials and methods: This study was a community-based, descriptive cross-sectional study carried out in July, 2012 in Shomolu Local Government Area (LGA of Lagos State, Nigeria. Multistage sampling method was employed to select the 290 respondents who participated in the study. Structured, pretested, interviewer-administered questionnaires were used for data collection. Data was analyzed with Epi-Info™ version 7. Results: The study revealed low awareness of HPV (27.9% and HPV vaccines (19.7% among the mothers that participated. There was a high awareness for cervical cancer but little knowledge of its link to HPV. Awareness and utilization of HPV vaccines increased with increasing educational level (P<0.05. There was a high willingness and intention among the mothers to vaccinate their girls (88.9% and to recommend the vaccine to others (91.0%. Accessibility and affordability of the HPV vaccines were found to be possible barriers to future utilization of the vaccines. Conclusion: Despite low knowledge about HPV and HPV vaccines, mothers were willing to vaccinate their daughters. We recommend improving mothers' knowledge by education and the possible inclusion of the vaccine in the national immunization

    Full Text Available The study examined effects of manpower planning and development in Lagos state civil service performance. Lagos state civil service is the greatest asset of the state in its quest for socio-economic development. The primary question that was explored is whether the nature of manpower planning and development curriculum in Lagos state civil service has effect on the service performance and the attainment of state objective. The study relied on primary and secondary data, and multiple stage sampling technique was used to select the sample population. The data collected was presented in frequency bar chart and simple percentage. Pearson’s Product Moment Correlation Coefficient (PPMC statistical tool was used to test the hypotheses. Findings of the study show that the nature of manpower planning and development curriculum has a positive effect on the Lagos state civil performance. It also reveals that the manpower planning and development has a positive effect on the attainment of Lagos state objective. To achieve better performance in the service, it should among others, improve on the current manpower planning strategy and continue to update its manpower development curriculum in line with the global best practices. Given the pivotal role that technology plays in the 21st century, the service should avail itself the windows of opportunities that information technology provides in its drive to enhance employees’ skills, knowledge and abilities that will invariably improve the service performance. Yet, the service should imbibe the prescripts of New PublicManagement theory (NPM, and that goals and targets should be defined and measurable as indicators of organizational performance.

    The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, completed hydrologic and hydraulic analyses to assess the potential hazard to human life and property associated with the hypothetical failure of the Lago El Guineo Dam. The Lago El Guineo Dam is within the headwaters of the Río Grande de Manatí and impounds a drainage area of about 4.25 square kilometers.The hydrologic assessment was designed to determine the outflow hydrographs and peak discharges for Lago El Guineo and other subbasins in the Río Grande de Manatí hydrographic basin for three extreme rainfall events: (1) a 6-hour probable maximum precipitation event, (2) a 24-hour probable maximum precipitation event, and (3) a 24-hour, 100-year recurrence rainfall event. The hydraulic study simulated a dam failure of Lago El Guineo Dam using flood hydrographs generated from the hydrologic study. The simulated dam failure generated a hydrograph that was routed downstream from Lago El Guineo Dam through the lower reaches of the Río Toro Negro and the Río Grande de Manatí to determine water-surface profiles developed from the event-based hydrologic scenarios and “sunny day” conditions. The Hydrologic Engineering Center’s Hydrologic Modeling System (HEC–HMS) and Hydrologic Engineering Center’s River Analysis System (HEC–RAS) computer programs, developed by the U.S. Army Corps of Engineers, were used for the hydrologic and hydraulic modeling, respectively. The flow routing in the hydraulic analyses was completed using the unsteady flow module available in the HEC–RAS model.Above the Lago El Guineo Dam, the simulated inflow peak discharges from HEC–HMS resulted in about 550 and 414 cubic meters per second for the 6- and 24-hour probable maximum precipitation events, respectively. The 24-hour, 100-year recurrence storm simulation resulted in a peak discharge of about 216 cubic meters per second. For the hydrologic analysis, no dam failure conditions are

    Full Text Available This paper examines the nature, growth and spatial pattern of industries within the Lagos Region. Industrial activities in this region grew progressively over the year from mere brickwork, palm oil mills, printing press, soap factory, and metal container factory to capital intensive manufacturing. Indeed, the number of industrial establishments increased from 122 in 1962 to 637 in 1993. Lagos developed into Nigeria's leading industrial center; especially following the expansion in its service and administrative sectors. Whereas, chemicals and pharmaceutical; and basic metal, iron and steel and fabricated metal products industry groups dominate in industrial scene, wood and wood products (including furniture; and non-metallic mineral products are rare. The spatial pattern shows that industrial establishments vary amongst the industrial estates/areas, and also among the industry groups. Ikeja/Ogballsheri industrial estate/area dominates the industrial scene.

    Full Text Available Urban travel is not solely the function of travel, but also on people’s participation in activities and how these were done. This study utilized 2,500 households’ samples in Lagos metropolis. The questionnaire about intra-city trip patterns was administered in direct proportion to the population size of each Local Government Areas (LGAs. Systematic sampling technique was used to select every tenth building on the identified streets. lt is observed that more than 95% of residents depends on roads, while less than 5% depends on Rail and Ferry. Work and business trips characterized the weekdays, while social, shopping and recreation trips dominate the weekends. This situation leads to too many vehicular traffic on the roads during the peak periods, leading to congestion and loss of valuable man-hours. Transportation planners in Lagos need to develop alternative intra-city transportation systems.

    2011-10-01

    Full Text Available Background: Child adoption is a recommended alternative form of infertility management. Infertility is of public health importance in Nigeria and many other developing nations. This is a result of its high prevalence and especially because of its serious social implications as the African society places a passionate premium on procreation in any family setting. Objectives: The aim of this study was to determine the knowledge, attitude and practice of child adoption amongst women attending infertility clinics in teaching hospitals in Lagos State and to determine the factors that influence their attitude and practice towards it. Method: A cross-sectional descriptive design was used. Data were collected by using a structured questionnaire which was interviewer-administered. The study was conducted in the two teaching hospitals in Lagos State (LUTH [Lagos University Teaching Hospital] and LASUTH [Lagos State University Teaching Hospital] from amongst 350 women attending the gynaecological clinics. All the patients under management for infertility at the gynaecology clinics during the period of the study were interviewed. Results: Many respondents (85.7% had heard of child adoption and 59.3% of them knew the correct meaning of the term. More than half of the respondents (68.3% said that they could love an adopted child but less than half of them (33.7% were willing to consider adoption. Only 13.9% has ever adopted a child. The major reason given for their unwillingness to adopt was their desire to have their own biological child. Factors that were favourable towards child adoption were Igbo tribe identity, an age above 40 years, duration of infertility above 15 years, and knowing the correct meaning of child adoption. Conclusion: There is a poor attitude to adoption even amongst infertile couples. Interventions need to be implemented to educate the public on child adoption, to improve their attitude towards adoption and to make it more acceptable.

  9. Murciélagos hematófagos como reservorios de la rabia

    Directory of Open Access Journals (Sweden)

    Karin Corrêa Scheffer

    Full Text Available La rabia continua siendo un desafío para las autoridades de salud pública y una limitante para la industria ganadera en América Latina. Caninos silvestres y domésticos, así como murciélagos hematófagos son las principales especies transmisoras y reservorios de la enfermedad. Actualmente, se observa variaciones en el perfil epidemiológico de la rabia, donde la especie de murciélago hematófago Desmodus rotundus se constituye en la principal especie transmisora. A lo largo del tiempo se ha acumulado conocimiento sobre la ecología, biología y comportamiento de esta especie y sobre la historia natural de la rabia, lo cual debe conducir a una continua evolución de los métodos de control poblacional de D. rotundus, prevención y técnicas de diagnóstico. Aún se desconoce la relación ecológica de esta especie con otras hematófagas y no hematófagas, y queda mucho por mejorar en los sistemas de notificación y vigilancia epidemiológica, así como crear una mayor conciencia entre los ganaderos ante el tema. La comprensión del impacto que las modificaciones ambientales inducidas por el hombre ejercen sobre la dinámica de infección del virus de la rabia en los murciélagos debe ser motivo de investigaciones posteriores. Esto requerirá la combinación de estudios de campo con modelos matemáticos y nuevas herramientas diagnósticas. La presente revisión pretende presentar los aspectos más relevantes sobre el rol de los murciélagos hematófagos como reservorios y transmisores del virus de la rabia

    LAGO is an extended cosmic ray observatory composed of water-Cherenkov detectors (WCD) placed throughout Latin America. It is dedicated to the study of various issues related to astrophysics, space weather and atmospheric physics at the regional scale. In this paper we present the design and implementation of the front-end electronics and the data acquisition system for readout of the WCDs of LAGO. The system consists of preamplifiers and a digital board sending data to a computer via an USB interface. The analog signals are acquired from three independent channels at a maximum rate of ~1.2×105 pulses per second and a sampling rate of 40 MHz. To avoid false trigger due to baseline fluctuations, we present in this work a baseline correction algorithm that makes it possible to use WCDs to study variations of the environmental radiation. A data logging software has been designed to format the received data. It also enables an easy access to the data for an off-line analysis, together with the operational conditions and environmental information. The system is currently used at different sites of LAGO.

    Full Text Available Nigeria as a developing nation is facing increasing demand for electricity especially in the residential areas. The use of compact fluorescent lamps (CFLs is one of the several measures towards reducing the demand. However, in Nigeria, the use of CFLs is low. The present study was designed to investigate some factors responsible for the low usage of CFLs in Lagos, Nigeria. Questionnaires were administered by hand on 984 households, selected through systematic random sampling techniques from 5 local government areas in Lagos State. The first building along the major street in each of the local government was selected randomly and every tenth building constituted the sample. A household head was surveyed in each of the building selected, and was asked to rate some factors that might have influenced the usage of CFLs. The data generated from the questionnaire were analysed using ranking method. The findings show that inability to measure the saving benefits of CFLs on electricity bills, lack of affordability and high initial cost of acquisition and installation were the most important factors which influence the use of the CFLs. The study concludes by providing some recommendations on how to achieve sustainable energy management in the Lagos and beyond through more efficient residential house lighting.

    Full Text Available Transformation means positive change to new values and direction. This research is concerned with the relationship between empowerment processes that are transformatory and gender equality in the workplace. Its scope includes integrating a transformatory view into women’s and men’s consciousness and autonomy over their career, education and health. This research adopted a case-study approach by using the Ministries of Education, Health, Establishment, Training and Pensions and the Civil Service Commission in Lagos State, employing a combination of qualitative and quantitative research methods as its empirical research methodology. The field work was carried out in Lagos State in the months of June and July, 2014 while the interview was in July and August, 2014. This study demonstrated that gender-blind policies disempower women and perpetuate gender inequalities in the Lagos State Civil Service. Further, it shows that the manifestation of transformatory empowerment is jeopardised by women and men's compliance with the existing expectations and inaction to bring about changes in policies and practices that are detrimental to the attainment of gender equality in the work place.

    Proper management and safe disposal of medical waste (MW) is vital in the reduction of infection or illness through contact with discarded material and in the prevention of environmental contamination in hospital facilities. The management practices for MW in selected healthcare facilities in Lagos, Nigeria were assessed. The cross-sectional study involved the use of questionnaires, in-depth interviews, focused group discussions and participant observation strategies. It also involved the collection, segregation, identification and weighing of waste types from wards and units in the representative facilities in Lagos, Nigeria, for qualitative and quantitative analysis of the MW streams. The findings indicated that the selected Nigerian healthcare facilities were lacking in the adoption of sound MW management (MWM) practices. The average MW ranged from 0.01 kg/bed/day to 3.98 kg/bed/day. Moreover, about 30% of the domestic waste from the healthcare facilities consisted of MW due to inappropriate co-disposal practices. Multiple linear regression was applied to predict the volume of waste generated giving a correlation coefficient (R(2)) value of 0.99 confirming a good fit of the data. This study revealed that the current MWM practices and strategies in Lagos are weak, and suggests an urgent need for review to achieve vital reversals in the current trends.

    Full Text Available A survey of medical waste management (MWM practices and their implications to health and environment was carried out in metropolitan Lagos. Lagos is currently the most populous and urbanized city in the country with an estimated population of over 13 million people. The study assessed management practices in four (2 privates and 2 publics hospitals ranging in capacity from 40 to 600 beds. Empirical data was obtained on medical waste generation, segregation, storage, collection, transportation and disposal. The observed MWM practices in all hospitals indicate absence of full compliance with the protocol for handling medical waste as stipulated in the relevant sections of the guidelines and standards for environmental pollution control in Nigeria. Three hospitals demonstrated high priority for segregation of infectious medical waste. Average generation rate of medical waste in the investigated hospitals ranged from 0.562 kg/bed.day to 0.670 kg/bed.day. Infectious waste accounts for between 26 to 37% of this volume. Only two of the hospitals investigated carry out treatment of their infectious and sharp waste types by incineration before final disposal. Burning and burial of medical waste is an unusual but common practice among the hospitals. All the hospitals employ the services of the state owned solid waste management company, the Lagos State Waste Management Authority (LAWMA for final collection, and disposal of their medical waste at government approved sites.

    Full Text Available “Lago de Guadalupe” is an important freshwater ecosystem located in the northern part of the metropolitan area surrounding Mexico City, under high demographic pressure. It receives approximately 15 hm3·y-1 of untreated municipal wastewater from the surrounding municipalities. In order to develop a comparative assessment of the pollution effect over the limnological characteristics of Lago de Guadalupe, this lake was characterised from February 2006 to July 2009, and the results were compared with those obtained from a non-polluted lake “Lago el Llano” located in the same drainage area. Lago de Guadalupe was hypereutrophic with anoxic conditions throughout most of the water column. In contrast, Lago el Llano was mesotrophic with high dissolved oxygen concentrations throughout the entire water column with a clinograde profile. Both reservoirs had a monomictic mixing regime. The longitudinal zonation of physicochemical and biological variables were investigated in order to better understand the processes controlling the water quality across the reservoir during its residence time. This study shows the impact of anthropogenic pollution on the limnological characteristics of a subtropical reservoir and confirms that under adequate management schemes, namely avoiding pollution and wastewater discharges, subtropical reservoirs can be prevented from developing eutrophic conditions.

    Martignano lake is a particular charming volcanic lake in the countryside of Rome. Recently it was included in a project of Regional Wildlife Park. The lack of immissaries and emissaries, the quite long renewal time and the very short homeothermic period of two-months in a year, make the lake susceptible of trophic evolution. The comparison between the present data and those from previous studies seems to confirm such a slow development towards this way, with a nutrient level (nitrate 0.97 mg/L; total phosphorus 11.14 {mu}g/L) and chlorophyll a concentrations (10.68 {mu}g/L), typical of mesotrophic waters. The analysis of nutrient data expressed as annual mean value in percentage from the coastal stations, suggests an under lied farming influence, and points out the need to adopt fast reduction measures, to lower the phosphorus load in acceptable levels for the lake ecosystem. [Italian] Il lago di Martignano (207 m.s.l.m) e' situato nell'Italia centrale, a 35 Km a nord di Roma. I laghi di origine vulcanica rappresentano una tipologia relativamente rara rispetto all'insieme dei corpi d'acqua componenti la limnologia classica. La loro esistenza si determina in regioni con passata o attuale pronunciata attivita' tettonica. La mancanza di immissari ed emissari che caratterizza questo invaso rende particolarmente vulnerabile il suo livello trofico da parte delle contaminazioni da insediamenti urbani ed agricoli circostanti. Ai fini di valutare l'attuale velocita' di ricambio idrico del lago, il suo livello trofico e la conseguente capacita' di automantenimento di un basso livello trofico delle acque, e' stato pianificato il presente studio articolato in 13 mesi di campionamento. Si e' constatato che il valore medio annuale della clorofilla a, 10.68 {mu}g/L, mentre la presenza dei nitrati si aggira sul valore medio di 0.97 mg/L, cio' permette di ipotizzare l'origine agricola della maggior parte dei nutrienti del

    The accident and emergency department constitutes one of the vital entry points of patients into the healthcare facility of the hospital the world over. It responds to and manages variety of cases in all the clinical areas and thus pr vides an insight to the quality of care available in the health institution. The aim of this study is to determine the pattern of cases seen as well as the causes of deaths at the adult accident and emergency department of the Lagos UniversityTeaching Hospital, Idi-Araba, Lagos. Retrospective review of records of all patients attended to at the adult accident and emergency department of the Lagos University Teaching Hospital in 2009 and 2010 was carried out. Data spread sheet was used to collect data on demographic indices, diagnosis, outcome, date admitted, date discharged and amount paid from casualty attendance register and Nurses' report books. Data was collated and analysed using Epi-Info version 3.4.1 statistical software package. Out of the 5,427 available patients' records reviewed, 4,761(87.7%) were recorded as "discharged alive", 546 (10.1%) were recorded as "died", while 120 (2.2%) were recorded as "brought in dead". Of those discharged alive, male attendance was 2,376 (49.10%) while that of the female was 2,385 (50.10%). Majority of these patients were aged 20-39 years and the mean age of the patients was 39.96 +/- 18.22 yrs. Majority of cases seen were medical in origin (53.7%) and highest medical case seen was cerebrovascular accident, Commonest cause of death was from medical cases [69.2%] (cerebrovascular accident 22.0%). Male mortality was 55.3% while female mortality was 44.7%, mean age was 46.86 +/- 17.61. Most affected age group was 40 - 59 years (35.4%) and highest number of death was seen in December. The commonest case seen as well as commonest cause of death was cerebrovascular accident.

    Full Text Available The paper reports a study carried out on the utilisation of the Internet by agricultural science teachers in Lagos state focusing on uses, practices, and barriers. A questionnaire was developed based on literature and was administered to 300 agricultural science teachers in Lagos schools. 275 questionnaires properly completed were analyzed. Data reveal that 130 teachers are using the Internet for teaching agricultural science in classrooms as well as for various activities that enhance their professional development. Nevertheless, it was found that agricultural science teachers in Lagos State have not fully utilised the Internet because of barriers related to time factor, accessibility, and facilities. It is suggested that for the proliferation of Internet practices, there needs to be an increase in funding for technology, an introduction of computer/technology education, a provision of pedagogical training for teachers, and a provision of administrational support.

    Full Text Available Background: Since the past two decades, the Lagos seaports have experienced vessel and storage yard cargo congestion, resulting in dwell times of about 30 days for containerised imports and high trade logistics costs. Objectives: The purpose of this study was to identify the critical factors that impact the operational efficiency of the Lagos seaports with a view to improving liner trade activities. Method: The study adopted an operational-based approach to understand the dynamics of the various interfaces of the port value chain. The research paradigm adopted for the study was therefore a combination of constructivism and post-positivism paradigms, which entailed the exploration and understanding of the various stakeholders in the port value chain. The epistemology of the research relied on the use of the exploratory sequential mixed method research technique (i.e. the qualitative approach followed by the quantitative approach at the operational level of port operations. Results: The result of the research showed that significant challenges exist and that some of these challenges cut across all functions of port operations. Challenges are experienced in the areas of corruption, trade fraud, transport infrastructure deficits, the absence of a supply chain culture and shortcomings in the execution of the ‘contract of customs’. Additionally, these factors include the deficiencies in services and facilities provided by state agencies and government-appointed service providers and private sector companies such as truckers, inland container depots, Inland Container Depots (ICDs and terminal operators. Conclusion: Specific recommendations are made to address the issues identified which, if implemented, could significantly address the current inefficiencies observed in the Lagos seaport’s operations.

  16. Recovery and recycling practices in municipal solid waste management in Lagos, Nigeria

    2007-01-01

    The population of Lagos, the largest city in Nigeria, increased seven times from 1950 to 1980 with a current population of over 10 million inhabitants. The majority of the city's residents are poor. The residents make a heavy demand on resources and, at the same time, generate large quantities of solid waste. Approximately 4 million tonnes of municipal solid waste (MSW) is generated annually in the city, including approximately 0.5 million of untreated industrial waste. This is approximately 1.1 kg/cap/day. Efforts by the various waste management agencies set up by the state government to keep its streets and neighborhoods clean have achieved only minimal success. This is because more than half of these wastes are left uncollected from the streets and the various locations due to the inadequacy and inefficiency of the waste management system. Whilst the benefits of proper solid waste management (SWM), such as increased revenues for municipal bodies, higher productivity rate, improved sanitation standards and better health conditions, cannot be overemphasized, it is important that there is a reduction in the quantity of recoverable materials in residential and commercial waste streams to minimize the problem of MSW disposal. This paper examines the status of recovery and recycling in current waste management practice in Lagos, Nigeria. Existing recovery and recycling patterns, recovery and recycling technologies, approaches to materials recycling, and the types of materials recovered from MSW are reviewed. Based on these, strategies for improving recovery and recycling practices in the management of MSW in Lagos, Nigeria are suggested

    Analyses of an ~ 6 m sediment core from Lago Paixban in Peten, Guatemala, document the complex evolution of a perennial wetland over the last 10,300 years. The basal sediment is comprised of alluvial/colluvial fill deposited in the early Holocene. The absence of pollen and gastropods in the basal sediments suggests intermittently dry conditions until ~ 9000 cal yr. BP (henceforth BP) when the basin began to hold water perennially. Lowland tropical forest taxa dominated the local vegetation at this time. A distinct band of carbonate dating to ~ 8200 BP suggests regionally dry conditions, possibly associated with the 8.2 ka event. Wetter conditions during the Holocene Thermal Maximum are indicated by evidence of a raised water level and an open water lake. The timing of this interval coincides with strengthening of the Central American Monsoon. An abrupt change at 5500 BP involved the development of a sawgrass marsh and onset of peat deposition. The lowest recorded water levels date to 5500–4500 BP. Pollen, isotope, geochemical, and sedimentological data indicate that the coring site was near the edge of the marsh during this period. A rise in the water table after 4500 BP persisted until around 3500 BP. Clay marl deposition from 3500 to 210 BP corresponds to the period of Maya settlement. An increase in δ13C, the presence of Zea pollen, and a reduction in the percentage of forest taxa pollen indicate agricultural activity at this time. In contrast to several nearby paleoenvironmental studies, proxy evidence from Lago Paixban indicates human presence through the Classic/Postclassic period transition (~ 1000 BP) and persisting until the arrival of Europeans. Cessation of human activity around 210 BP resulted in local afforestation and the re-establishment of the current sawgrass marsh at Lago Paixban.

  18. Lake-level variations and tides in Lago Argentino, Patagonia: insights from pressure tide gauge records

    2015-08-01

    Full Text Available Based on precise pressure tide gauge observations lake-level records are derived for two sites in Lago Argentino, southern Patagonia, of 2.5 and 1 years of duration. Applying the tools of time series analysis, the principal processes affecting the lake level are identified and quantified. Lake-level changes reflecting variations in lake volume are dominated by a seasonal cycle of 1.2 m in amplitude. Lake-volume changes occur in addition with a daily period in response to melt water influx from surrounding glaciers. Sporadic lake-volume jumps are caused by bursting of the ice dam of Perito Moreno glacier. Water movements in Lago Argentino are dominated by surface seiches reaching 20 cm in amplitude. Lake tides reach a maximum amplitude of 3 mm. The comparison of the tidal signal extracted from the lake-level observations with a model composed of the contributions of body tide and ocean tidal loading indicates a phase shift of 23° which is most likely explained by an 1 hour phase lag of global ocean tide models in the region of the highly fragmented Pacific coast. The comparison of the obtained results with those of a previous study of Lago Fagnano, Tierra del Fuego, allows to relate differences in the hydrological and hydrodynamic processes between both lakes to morphological properties. This leads to a tentative prediction of the lake-level variability to be expected from other great Patagonian lakes. The presented geodetic results shall serve as a starting point for a detailed limnological investigation of these aquatic ecosystems.

    Full Text Available Aquaculture has shown capacities to serve as means of livelihood, improve living standards, provide employment and generate foreign exchange in many countries. Recent investment in Nigerian aquaculture has been target towards catfish farming. However, small quantity and poor quality fish seeds are one of the problems limiting production. Consequently, Lagos State government introduced improved breeding and hatchery management practices as a package to fish hatchery operators with the aim of improving fish seed quantity and quality in the state. Nevertheless, the dissemination of the package has not yielded the desired result. This study assessed the constraints to adoption of improved hatchery management practices among catfish farmers in Lagos State. With structured questionnaire, 150 catfish farmers, randomly selected from 12 local government areas spread across Lagos State were interviewed. Despite that majority of the respondents strongly agreed or agreed to the fact that improved hatchery management practices have positive impacts on breeding, hatching, and survival of fish fry, majority of them affirmed that high cost of acquisition, high technicality in using the improved management practices as well as inadequate information about the improved management practices are primary reasons for non-adoption of some of the improved practices. Some of the limitations faced by the respondents include insufficient capital, lack of technical expertise to use the methods adequately, non-availability of inputs, expensive cost of facility maintenance, poor information dissemination and insufficient technical support from the extension agents and the state government. Although the adoption of improved practices has not been total, due to these constraints, the farmers’ knowledge of the improved hatchery management practices is broad. There is a need for the state government to subsidize the improved hatchery technologies and inputs, in addition to

    Full Text Available Background: The Lagos State Regulation of Smoking Law was passed in February 2014 and stipulates the total restriction of tobacco smoking in listed public places. Workers in hospitality venues are at a high risk of exposure to second-hand smoke (SHS. Therefore, their awareness of the health risks, attitudes toward SHS and their reported levels of exposure may play a crucial role in developing an effective monitoring, implementation, and enforcement mechanism. Methods: We conducted a cross-sectional, descriptive study among workers in restaurants, bars, and nightclubs registered with the Lagos State Ministry of Tourism in the second quarter of the year 2014. We used a multistage sampling technique to select one respondent each from the 300 centers randomly selected to participate in the survey. Data were collected using a modified version of the World Health Organization Global tobacco surveillance system tools. Univariate and bivariate analysis were carried out. Exposure to SHS in the workplace and in other public places was treated as the outcome variable in the bivariate analysis. Results: Majority (75.3% of the respondents were aged between 21 and 40 years with a mean age of 27.7 + 8.6 years. Many (66% were waiters/waitresses and spent more than 8 h a day. Most (60.6% of the venues were indoor only establishments, and 26.8% had no form of smoking restrictions. Majority of the respondents were exposed to SHS at work, and this was higher in bars and nightclubs. A bivariate analysis of results showed that workers were exposed to SHS at work irrespective of workplace smoking restrictions or respondents smoking status. Conclusion: Our study demonstrates that second-hand smoke exposure is very high (65% in smokers; 65.6% in nonsmokers among workers in restaurants, bars, and nightclubs in Lagos State. We are therefore of the opinion that strict enforcement of law would ensure the protection of these workers.

    The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, completed a hydrologic and hydraulic study to assess the potential hazard to human life and property associated with the hypothetical failure of the Lago de Matrullas Dam, located within the headwaters of the Río Grande de Manatí. The hydrologic study yielded outflow hydrographs and peak discharges for Lago de Matrullas and other subbasins in the Río Grande de Manatí hydrographic basin for three extreme rainfall events: (1) a 6-hour probable maximum precipitation (PMP) event, (2) a 24-hour PMP event, and (3) a 100-year-recurrence, 24-hour rainfall event. The hydraulic study simulated the hypothetical dam failure of Lago de Matrullas using hypothetical flood hydrographs generated from the hydrologic study and selected dam breach parameters. The flood wave resulting from the failure was downstream-routed through the lower reaches of the Río Matrullas, the Río Toro Negro, and the Río Grande de Manatí for determination of water-surface profiles developed from the event-based hydrologic scenarios and “sunny day” (no precipitation) conditions. The Hydrologic Modeling System (HEC–HMS) and the River Analysis System (HEC–RAS) computer programs, developed by the Hydrologic Engineering Center (HEC) of the U.S. Army Corps of Engineers, were used for the hydrologic and hydraulic modeling, respectively. The flow routing in the hydraulic analyses was performed using the unsteady-state flow module available in the HEC–RAS model.

    A modern and efficient infrastructure is a basic necessity for economic development and integration into the global economy. The specific problem was the inadequate and unreliable supply of electricity to manufacturing corporations in Lagos, Nigeria. The purpose of the current quantitative correlational research study was to examine if there was a correlation between electricity supply efficiency and organizational growth and profitability in manufacturing corporations in Lagos, Nigeria. The population of the current correlational research study involved 28 out of 34 manufacturing corporations from various industrial sectors in Lagos, Nigeria, that are listed and traded on the Nigerian Stock Exchange. Spearman rho correlations were used to assess the relationships between independent variables of electricity supply efficiency levels and the dependent variables of organizational growth and profitability. The result of the correlational analysis of the data revealed that there was a statistically significant, strong positive correlation between the Average Gross Income (1998-2007) and Average Actual Electricity supply efficiency level (1998-2007), rho = 0.57; p = 0.002. A statistically significant, strong positive correlation was found between the Average Balance Sheet Size (1998-2007) and Average Actual Electricity Supply Efficiency Level (1998-2007), rho = 0.54; p = 0.003. A statistically significant, strong positive correlation between the Average Profit After Tax (1998-2007) and Average Actual Electricity Supply Efficiency Level (1998-2007), rho = 0.60; p = 0.001, was found. No statistically significant correlation between the Average Return on Investment (1998-2007) and Average Actual Electricity supply efficiency level (1998-2007), rho = 0.19; p = 0.33, was discovered.

    A series of lagoons can be found along the coastline of Rio de Janeiro, in the so-called Regiao dos Lagos. The lagoons differ in size, physicochemical, sedimentological and biological characteristics. Rare examples of litifying microbialites that produce stromatolites, the oldest fossils on Earth, can be found living in this lagoon system. The occurrence of stromatolites in the region is of great scientific interest because it enables the study of possible analogues of the earliest life on Earth. However, this region has been suffering from intense human activities and degradations. Geoconservation planning requires an assessment of the characteristics of the region and its potential threats. The primary goal of this study is to assess physical environmental changes and anthropogenic impacts over the last four decades in Regiao dos Lagos. Using a broad integrative assessment combining remote sensing, GIS, field studies and local knowledge of communities, land-cover and land-use classes were identified, as well as the main human activities impacting the environment. The seasonal and weekend tourism and urban sprawl in this coastal area of Rio de Janeiro triggers the occupation of new areas and the removal of natural vegetation, especially on lagoon margins. This disorderly occupation by an ever increasing population, with both legal and illegal constructions and the subsequent overload of the local infrastructure, e.g. increase of electrical energy consumption, volume of vehicles, pollution in air, water and soil and problems with water supply and wastewater treatment, are hastening the gradual degradation of the lake ecosystem. The main driving forces to environmental changes over the last four decades in Regiao dos Lagos were the change of dense vegetation, saline and bare soil classes into built-up areas, adding to the poor waste treatment and inadequate sewage disposal. This analysis provides a basis for a better control of anthropogenic impacts and

    Full Text Available Este estudo teve por objetivo reconstituir as mudanças paleoambientais e paleohidrológicas no baixo Amazonas. Um testemunho de sedimento foi coletado no Lago Santa Ninha, na várzea do Lago Grande de Curuai, localizada na margem direita do Rio Amazonas a aproximadamente 850 km da foz. O teor de água, a granulometria, as datações com carbono 14, os conteúdos de carbono orgânico e nitrogênio total e o isótopo estável do carbono (δ13C foram utilizados para determinar os processos sedimentares a que o meio esteve submetido. O testemunho estudado possui 270 cm de comprimento que corresponde a um período de 5600 anos cal AP. Este estudo colocou em evidência diferentes ambientes sedimentares: na base do testemunho até 4900 anos cal AP há uma vegetação inundada que foi gradualmente substituida por bancos de gramíneas e por uma planicie com secas sazonais em 4000 anos cal AP até alcançar, desde 600 anos AP as condições atuais deste lago. Estas alterações podem ter ocorrido em decorrência de mudanças no ciclo hidrológico do Rio Amazonas que, por sua vez, também são reflexos de alterações climáticas.Physical, chemical and geochemical characteristics of lacustrine sediments were studied to reconstruct paleohydrologyical control on sedimentation in an Amazonian floodplain. A core was collected at the Lago Grande de Curuai floodplain, in the Santa Ninha Lake, located on the right margin of the Amazon River at 850 km of the estuary. Water content, granulometry, radiocarbon dating, organic carbon, nitrogen content and δ13C were used to characterize the sedimentary processes. The core is 270 cm-long which corresponds to 5600 cal years BP. The core points out different sedimentary environments: flooded vegetation at the base of the core till 4900 cal years BP is substituted by grass banks changing to a floodplain encompassing prolonged annual dryness at 4000 cal years BP.

    We report the first in vitro and genetic confirmation of Malarone (GlaxoSmithKline; atovaquone and proguanil hydrochloride) resistance in Plasmodium falciparum acquired in Africa. On presenting with malaria two weeks after returning from a 4-week visit to Lagos, Nigeria without prophylaxis, a male patient was given a standard 3-day treatment course of Malarone. Twenty-eight days later the parasitaemia recrudesced. Parasites were cultured from the blood and the isolate (NGATV01) was shown to be resistant to atovaquone and the antifolate pyrimethamine. The cytochrome b gene of isolate NGATV01 showed a single mutation, Tyr268Asn which has not been seen previously.

    Full Text Available Los lagos de alta montaña, con una baja mineralización, alcalinidad y contenido de nutrientes, son ecosistemas sensibles a perturbaciones naturales o antropogénicas y en la actualidad están amenazados por el calentamiento global. En México existen dos lagos de alta montaña (> 3,800 m snm: La Luna y El Sol, en el cráter del Nevado de Toluca. Análisis de parámetros químicos y de diatomeas en sedimentos superficiales permiten identificar que La Luna es más ácido y menos mineralizado que El Sol y que a pesar de su proximidad geográfica cada lago tiene un conjunto de diatomeas característico, con menor abundancia y riqueza específica en La Luna. En este lago dominan Encyonema perpusillum y Psammothidium helveticum y en El Sol Cavinula pseudoscutiformis , Psammothidium levanderi y Aulacoseira distans. Con base en esta distribución se interpreta el registro de diatomeas de una secuencia sedimentaria de La Luna, de 57 cm, fechada con 210 Pb y 14 C en la que también se realizaron análisis de contenido de cladóceros y de susceptibilidad magnética. Todos estos indicadores permiten ubicar el inicio de una tendencia hacia climas secos y fríos alrededor de los años 1350 y 1510, que corresponde a la Pequeña Edad de Hielo (PEH, la cual tiene su máxima expresión entre los años 1660 y 1760, durante el mínimo de actividad solar de Maunder. Las características ambientales de sequía y frío se observan hasta principios del siglo XX. La comparación de este registro con otros disponibles permite concluir que durante la PEH hubo una tendencia regional en el centro de México hacia climas secos.

  11. Anti-malarial drug quality in Lagos and Accra - a comparison of various quality assessments

    2010-06-01

    Full Text Available Abstract Background Two major cities in West Africa, Accra, the capital of Ghana, and Lagos, the largest city of Nigeria, have significant problems with substandard pharmaceuticals. Both have actively combated the problem in recent years, particularly by screening products on the market using the Global Pharma Health Fund e.V. Minilab® protocol. Random sampling of medicines from the two cities at least twice over the past 30 months allows a tentative assessment of whether improvements in drug quality have occurred. Since intelligence provided by investigators indicates that some counterfeit producers may be adapting products to pass Minilab tests, the results are compared with those from a Raman spectrometer and discrepancies are discussed. Methods Between mid-2007 and early-2010, samples of anti-malarial drugs were bought covertly from pharmacies in Lagos on three different occasions (October 2007, December 2008, February 2010, and from pharmacies in Accra on two different occasions (October 2007, February 2010. All samples were tested using the Minilab® protocol, which includes disintegration and active ingredient assays as well as visual inspection, and most samples were also tested by Raman spectrometry. Results In Lagos, the failure rate in the 2010 sampling fell to 29% of the 2007 finding using the Minilab® protocol, 53% using Raman spectrometry, and 46% using visual inspection. In Accra, the failure rate in the 2010 sampling fell to 54% of the 2007 finding using the Minilab® protocol, 72% using Raman spectrometry, and 90% using visual inspection. Conclusions The evidence presented shows that drug quality is probably improving in both cities, especially Lagos, since major reductions of failure rates over time occur with all means of assessment. Many more samples failed when examined by Raman spectrometry than by Minilab® protocol. The discrepancy is most likely caused by the two techniques measuring different aspects of the medication

    Full Text Available We compared the recent history of living planktonic diatom assemblages in Lago Maggiore with the remains found in the topmost section of 14 sediment cores taken from the lake. Sediment samples showed a marked domination of planktonic taxa, but a significant proportion of benthic taxa was found in cores collected close to river mouths. Between-core variability in diatom assemblage and in diatom-inferred total phosphorus concentration was also estimated. The implications of our results for calibration data sets relating environmental variables to diatom assemblages are also discussed.

    Full Text Available Sexual violence against females is a public health problem. This descriptive cross-sectional study sought to determine the prevalence of sexual violence among out-of-school female adolescents in Lagos, Nigeria and examine the context in which it occurs. Three hundred and fifty adolescents, between the ages of 10 and 19 years, working in Sandgrouse market, Lagos, were selected using cluster sampling. Data were collected using an interviewer-administered questionnaire. Almost half (42.9% of the respondents have had sexual intercourse, and median age at initiation was 17 years. Forced initiation was reported by 15.8%, and 36.3% reported that first intercourse was due to coercion. Among the sexually active, only 12.3% stated that “it is what they desire.” Majority of respondents (64.1% believe that rape is common in their community, and 18% of the sexually active have experienced rape. Out-of-school adolescents in this community are at risk of sexual violence. The factors that make them vulnerable need to be addressed.

    Full Text Available The phenomenon of climate change heralds distinctive challenges for sub-Saharan Africa’s urban areas, with economic, social, and health impacts, and severe effects on housing and infrastructure. This study examined climate-change induced vulnerabilities including the urban housing crisis and homelessness in the context of Lagos mega-city, Nigeria, with a view to defining the potential lessons to learn from the Asian urban experience. The study conducted case-study analyses of Lagos and the Asian urban experience, highlighting the megacity-related vulnerabilities. It identified gender and aging as key factors in understanding vulnerability. Lessons from Asia relate to: the conscious policy-linkage of urban demographic expansion and economic growth; synergy between formal and informal sectors; urban densification through compact, mixed-land use development; broad-based urbanization; metropolitan expansion; pursuit of slum-free cities; prominence of housing in national policies; pro-poor financial frameworks; and extensive adoption of mitigation and adaptation strategies in the coastal conurbations. The paper concluded on the critical role of urban governance in reducing vulnerability, the need for greater multi-disciplinary stakeholders’ collaboration and partnership, and the expediency of fitting adaptation strategies and resilience responses to specific needs, capacities and priorities of impact groups. These could enhance the transformation of mega-cities into more adaptable and resilient urban systems.

    Full Text Available The study assessed allocation, criteria and allotment effectiveness of performance risks in Build- Operate-Transfer (BOT transportation infrastructure in Nigeria using Lagos Infrastructure Project (LIP as a case study. LIP is the only BOT-procured tolled road that has attained ‘operate’ stage of BOT cycle in Nigeria. It revealed that more operating risks were actually allocated to the concessionaire than the grantor and most of the risks were preferred retained by the allottee. Significant fraction of the risks was effectively allocated between the concessionaire and grantor except those that involve close interface between participants. While grantor rated nine risks high and seven risks very high; the concessionaire assessed nine risks to be high and five risks to be very high; the grantor rated the effectiveness level to be seventy three per cent and the concessionaire assessed it to be sixty four per cent. The study recommended that the evolving knowledge from Lagos Infrastructure Project (LIP should be documented to guide future BOT transactions in Nigeria.

    Retinopathy of prematurity (ROP), thought to be rare in Nigeria, sub-Saharan Africa, has been reported in recent studies. Developing cost-effective screening is crucial for detecting retinal changes amenable to treatment. This study describes the use of an iPhone combined with a 20-D lens in screening for ROP in Lagos, Nigeria. The ROP screening program was approved by the Lagos University Teaching Hospital Ethical Committee. Preterm infants with birthweight of less than 1.5 kg or gestational age of less than 32 weeks were screened. In conjunction with the neonatologist, topical tropicamide (0.5%) and phenylephrine (2.5%) was used to dilate the pupils. A pediatric lid speculum was used. Indirect ophthalmoscopy was used to examine the fundus to ensure there were no missed diagnoses. An iPhone 5 with 20-D lens was used to examine the fundus. The App Filmic Pro was launched in the video mode. The camera flash served as the source of illumination. Its intensity was controlled by the app. The 20-D lens was used to capture the image of the retina, which was picked up by the camera system of the mobile phone. Another app, Aviary, was used to edit the picture. The images captured by the system were satisfactory for staging and determining the need for treatment. An iPhone combined with a 20-D lens appear to be useful in screening for ROP in resource-poor settings. More studies are needed in this area.

    Lagos is one of the fastest growing cities in Africa, which is grappling with the challenges of poorly managed urbanisation. With an estimated population of about 17.5 million, solid waste management is one of the most pressing environmental challenges currently faced in the city. It is estimated that more than 9071847.4kg of urban waste is generated every day in the city. The city lacks the capacity to deal with such magnitude of waste. Consequently, the city has involved the private sector (private sector participation) in its waste management drive. This article examines the effectiveness of this public-private sector collaboration model in waste management in informal settlements in Lagos using empirical data. Major findings of the article include the irregularity of waste collection owing to a poor road network, an inadequate transport infrastructure and the desire to maximise profit, as well as poor waste handling and disposal methods by the private sector participation operators who are not chosen based on competence and capacity to perform. Another major finding is the lack of cooperation from residents evidenced in non-payment of bills and poor packaging of wastes, resulting in wastes being littered. The article concludes on the need to restructure the scheme through proper sensitisation of residents, selection of operators with demonstrable delivery capacity and provision of a well-maintained road network to facilitate access of operators to settlements. © The Author(s) 2016.

    Solid waste management in Lagos, Nigeria includes refuse collection and transportation to a landfill site. Disposal of the refuse and maintenance of the landfill site is also included in this task which, in the past was always a responsibility of the Government Agencies at the local level as a social service. This service has recently been privatised in the name of Private Sector Participation (PSP) in domestic refuse collection and disposal. As a new operator in about 23 wards in the ongoing PSP of domestic refuse, Richbol Environmental Ltd., recognized the enormous effort that government will have to make to sustain PSP in solid waste management. Governments can maintain control through re-orientation, legislation, enforcement, strengthening the PSP operators, integrating existing operators, and monitoring the activities of PSP operators. This paper presented a brief overview of the institutional changes that solid waste management has undergone in Lagos since 1977. It was emphasized that integrated waste management is extremely capital intensive. An integrated PSP can be a long term solution to waste management in developing, cash poor countries. The economic importance of PSP lies in the fact that it will reduce government expenditure and will also create a healthier environment and provide employment opportunities for thousands of employees and contribute to the gross domestic product of the country. 5 refs., 3 tabs., 1 fig.

    Several body of knowledge have noted the importance of wetland ecosystems in climate moderation, resource supply and flood risk reduction amongst others. Relevant as it may, rapidly increasing population and uncontrolled urban development poses a challenge in some regions and require understanding of the ecosystem components and drivers of change over a long period of time. Thus, the main thrust of this paper is to analyse multiple drivers of wetland ecosystems degradation in the last 30 years in the Lagos megacity using field study, desktop review, satellite data and laboratory analysis. Key drivers identified includes: conversion of wetlands to settlements and waste sink, land use planning that neglects wetland conservation and restoration, ineffective legal status for wetlands, over exploitation leading to degradation and fragmentation of wetland ecosystems governance. In stemming further loss of this vital ecosystem, this study adopted and proposed respectively, the Drivers, Pressure, State, Impact and Response (DPSIR) and Integrated Planning Approach (IPA) frameworks in analysing policy and governance issues in wetland development. These analyses figured out amongst others, strict conservation and sustainable use of wetland resources, habitat restoration, climate adaptation measures, legal protection and wetland management institution as major responses to current multiple pressures facing wetland ecosystems in Lagos. For these frameworks to be made meaningful, weak coordination among government agencies and institutional capacity in implementation and law enforcement, unsustainable resource extraction by private/business organization and issues on alternative sources of income on the part of the local communities amongst others needs to be addressed.

    Full Text Available This study examines the effect of neighborhood deprivation on the perception of the individuals about their own health in Lagos State, Nigeria. Respondents were required to rate their own health as "excellent, very good, good, fair, poor and very poor". The questionnaire contained questions on various aspect of the respondents neighborhood and their perception about them. It was found that most neighborhoods in Lagos State are deprived of basic essentials of life such as electricity, water, good roads and security. Over 43% of the respondents claimed to have visited a hospital two or more times and 43.7% had lost at least two neighbors in the past one year. Over half (57.8% of the respondents rated their own health as good, 36.6% ranked their own health as fair while only 5.6% claimed to have poor health. A fitted regression model ( r2 = 0.644 showed that variables such as number of dependants, income, occupation, type of residential accommodation, ownership of house, number of rooms occupied, mode and convenience of transportation, accessibility to water, electricity and good roads and security jointly determine the perception of an individual about his own health status.Key Words: Neighborhood, Deprivation, Self Rated Health, Security, ResidenceDOI = 10.3126/dsaj.v2i0.1364Dhaulagiri Journal of Sociology and Anthropology Vol.2 pp.193-210

    Thermoluminescence (TL) and optically stimulated luminescence (OSL) dating are two important techniques for dating archaeological and geological material, especially suitable for archaeological ceramics, where samples for 14 C dating are not available. In this work, five pottery shards from Osvaldo and Lago Grande archaeological sites were dated by OSL. For measurements, it was used the SAR protocol. The annual dose rates were estimated by the contents of U, Th and K, determined by instrumental neutron activation analysis (INAA) of the pottery shards and clay samples near both sites. Lago Grande and Osvaldo represent a microcosm of the region, and their proximity and high density of archaeological record turn them interesting to study possible relations of cultural and/or commercial exchange. Calculations showed that the water content is an important variable that cannot be neglected in OSL dating of pottery shards from central Amazon, due to the high humidity in regional soils. The results between 867 ± 101 and 1154 ± 62 years AD agreed with the average time span for the archaeological sites occupation found in the literature. (author)

    The macroscopic characteristics of archaeological ceramics, such as the surface decoration and shape, are used as cultural and chronological indicators of ancient people. The combination of stylistic-typological studies with archaeometric analysis, as provenance studies, has been considered of great importance in Archaeology. The purpose of this paper is to contribute to the understanding of the pre-colonial Amazonian occupations. Inside this context, fifty ceramic fragments from the Lago Grande archaeological site were analyzed by INAA in order to characterize its elemental composition. The results were treated with multivariate statistics: Cluster, Principal Components and Discriminant Analysis. The results obtained by these three methods were compared in an effort to achieve some correlation with the archaeological context. It was stated the existence of two different groups of artifacts. They probably regard to the main ceramic phases found in the site excavation: Paredao and Manacapuru. Once confirmed by other archaeological analyses, these results could corroborate an exchange net among the former inhabitants of Lago Grande and other sites in the neighborhood. (author)

    This study sought to determine the oral health care knowledge and practices of a group of deaf adolescents in Lagos. The study involved 50 students of Wesley School 1 for the Deaf, Lagos (26 males and 24 females, aged 10-19 years, mean 13.3 +/- 2.8). Information about previous dental care, oral hygiene, and snacking habits were obtained through a questionnaire and sign language by the teachers. Only 12 percent of pupils had received dental care. Eight percent and 72 percent, respectively, gave correct answers to causes of tooth decay and bleeding gums. Ninety-four percent brushed their teeth once daily, with no significant sex difference (P > .05). Reported dental problems include bleeding gums (36%), tooth discoloration, and tooth decay. The majority of pupils (60%) preferred biscuits and soft drinks as snacks. More than 90 percent were willing to have a dental check-up. The oral health knowledge and practices of this group of children will improve through a controlled school-based oral health education program.

At the first stage, the researchers purposively selected Ikorodu L.G.A in Lagos State. At the researchers selected two schools (1 Private schools, & 1 Public schools, using simple random technique. Thus, a total of two schools were picked in each of the L.G.A. Finally, simple random sampling was used in selecting eighty students in each L.G.A, thus making a total of two hundred and forty Senior Secondary students that participated in the study. Six hypotheses were generated for the purpose of this study. Data were gathered using a researcher designed instrument tagged “Influence of Counselling Service on Academic Performance of Students Questionnaire (ICAPSQ. The findings of this study showed that there was no significant difference on the basis of age, class level and school type. However a significant difference was found on the basis of respondent’s religion, gender and the number of times the students visited the counselor. It was therefore recommended that the ministry of education should ensure that guidance and counselling units are established in all public and private secondary schools in Nigeria.

    Human papillomavirus (HPV) is one of the most common sexually transmitted infections in sexually active adolescents and young women and has been implicated as a cause of the majority of cases of cervical cancer, which is the second most common cancer in women in Nigeria. HPV is preventable with the use of HPV vaccines. The objective of this study was to assess mothers' HPV knowledge and their willingness to vaccinate their adolescent daughters in Lagos, Nigeria. This study was a community-based, descriptive cross-sectional study carried out in July, 2012 in Shomolu Local Government Area (LGA) of Lagos State, Nigeria. Multistage sampling method was employed to select the 290 respondents who participated in the study. Structured, pretested, interviewer-administered questionnaires were used for data collection. Data was analyzed with Epi Info™ version 7. The study revealed low awareness of HPV (27.9%) and HPV vaccines (19.7%) among the mothers that participated. There was a high awareness for cervical cancer but little knowledge of its link to HPV. Awareness and utilization of HPV vaccines increased with increasing educational level (P knowledge about HPV and HPV vaccines, mothers were willing to vaccinate their daughters. We recommend improving mothers' knowledge by education and the possible inclusion of the vaccine in the national immunization schedule to eliminate the financial barrier.

    Across the world, basic medical scientists and physician scientists work on common platforms in state-of-the-arts laboratories doing translational research that occasionally results in bedside application. Biotechnology industries capitalise on useful findings for colossal profit.1 In Nigeria and the rest of Africa, biomedical science has not thrived and the contribution of publications to global high impact journals is low.2 This work investigated facilities available for modern biomedical research in Lagos public universities to extract culprit factors. The two public universities in Lagos, Nigeria were investigated by a cross sectional questionnaire survey of the technical staff manning biomedical science departments. They were asked about availability of 47 modern biomedical science research laboratory components such as cold room and microscopes and six research administration components such as director of research and grants administration. For convenient basic laboratory components such as autoclaves and balances, 50% responses indicated "well maintained and always functional" whereas for less convenient complex, high maintenance, state-of-the-arts equipment 19% responses indicated "well maintained and always functional." Respondents indicated that components of modern biomedical science research administration were 44% of expectation. The survey reveal a deficit in state-of the-arts research equipment and also a deficit in high maintenance, expensive equipment indicating that biomedical science in the investigated environment lacks the momentum of global trends and also lacks buoyant funding. In addition, administration supporting biomedical science is below expectation and may also account for the low contributions of research articles to global high impact journals.

    Full Text Available El presente artículo aborda el proceso de reapropiación del lago de Chapala, México. En las últimas décadas se han venido transformando el suelo y la producción agrícola en los municipios ribereños del lago de Chapala debido a la introducción de cultivos de exportación mediante sistemas modernos de producción tecnificada. Por lo que los cultivos tradicionales han ido disminuyendo o se producen con mayor uso de pesticidas, fertilizantes y agroquímicos. El papel del campesino ribereño también se ha modificado debido a que las agroempresas trasnacionales generan una estructura de renta o compra de suelos y parcelas que utilizan durante un periodo de años, perdiendo el dueño el uso de sus tierras a cambio de un ingreso seguro. En el escenario ribereño actual, el campesino se transforma en receptor económico y, en ocasiones, en trabajador de sus propias tierras, sin posibilidad de decisión sobre ellas. Por lo que se encuentran en peligro los saberes locales históricos de las poblaciones ribereñas así como su cultura lacustre.

Desde 2009 se han observado floraciones extensivas de cianobacterias en el lago, reflejando la contaminación del agua en la cuenca. Se determinaron los niveles de arsénico (As y mercurio (Hg en agua superficial del lago de Atitlán, por espectrofotometría de absorción atómica (EAA, en cuatro muestreos realizados en marzo, mayo, agosto y octubre de 2014 en 14 sitios. Diez sitios se encuentran localizados en el lago, habiendo sido definidos en estudios anteriores con base en su cercanía a poblaciones asentadas en la orillas del lago. Dos sitios corresponden a los principales ríos tributarios, y los restantes dos sitios a la entrada y salida de la planta de tratamiento Los Cebollales, ubicada en Panajachel. Los niveles de As encontrados en el lago de Atitlán, tributarios y en la planta de tratamiento, fueron superiores a 20 μg/L. Los resultados indican que la contaminación del lago de Atitlán por As se debe principalmente a la geología de la cuenca, al localizarse en una zona volcánica. Los niveles cuantificables de As, son superiores al nivel máximo permitido para agua potable en la Norma de Agua Potable (NGO 29001:99 de la Comisión Guatemalteca de Normas (COGUANOR, por lo que el agua del lago de Atitlán no se considera apta para el consumo humano.

    Full Text Available Un tema muy debatido ha sido el de la estatura de las poblaciones aborígenes tardías del sur de Patagonia la cual, de acuerdo con los estándares europeos del siglo XVI, ha sido descripta como excepcional. Una muestra osteológica recientemente recuperada que permite aproximarse a este problema, es la procedente del lago Salitroso (N.O. de la provincia de Santa Cruz. La misma, constituida por un mínimo de 60 individuos de diferente sexo y edad, corresponde a distintos momentos del Holoceno tardío (ca. 2500 a 300 años 14C AP. La estimación de la estatura a partir de medidas lineales de huesos largos de muestras arqueológicas constituye un problema complejo, debido a la gran variedad de ecuaciones existentes en la literatura. Las mismas, derivadas de diferentes muestras de referencia, producen resultados muy disímiles que, en nuestro caso de estudio, varían (valores medios entre 168 y 177 mm en individuos masculinos y entre 162,7 y 165 mm en femeninos. El objetivo del presente trabajo es discutir una serie de criterios (v.g. proximidad genética, similitud ambiental y de proporciones corporales entre la muestra problema y la de referencia que resulten aplicables en el proceso de selección de las ecuaciones, con el fin de derivar estimaciones mas adecuadas y realistas de la estatura en muestras arqueológicas.

    Full Text Available A fines de la década del '80, se ha producido en nuestro país un sostenido desarrollo de los estudios bioarqueológicos orientados a obtener información relevante para discutir diversos aspectos del proceso evolutivo y adaptativo de las poblaciones prehistóricas. Los proyectos realizados y aquellos en desarrollo, presentan un marcado énfasis regional y consideran una amplia gama de indicadores biológicos referidos a aspectos tales como las pautas de salud, nutrición, dieta y actividad de poblaciones correspondientes a distintos períodos del Holoceno. En la Región Pampeana, los trabajos bioarqueológicos llevados a cabo hasta el presente, son escasas las consideraciones sobre el sector comprendido por el Borde Occidental de la Provincia de Buenos, e inexistentes en el Sur de la Provincia de Santa Fe. El presente trabajo está orientado a analizar desde una perspectiva Bioarqueológica, la interrelación entre los procesos bioculturales y paleoambientales en distintos ambientes ecotonales de la Pampa Húmeda. Específicamente se halla abocado al análisis comparativo de sectores con características ecológicas diferentes, ya que se trata de áreas de transición, factor que probablemente influyó en la toma de decisiones por parte de los grupos humanos que habitaron la región a través del tiempo. El objetivo general es estudiar la variabilidad en los modos de uso del espacio y adaptación biocultural por parte de los pobladores de ambientes ecotonales pampeanos. La particularidad ambiental del área de estudio y la variedad del registro bioarqueológico, permiten suponer que la información generada de este modo contribuirá a aumentar y complejizar el conocimiento acerca de los procesos que estructuran el registro arqueológico a distintas escalas espaciales y temporales como un paso necesario para la comprensión de la evolución y adaptación de las poblaciones humanas.

    Full Text Available A través de este texto se pretende dar a conocer cómo las rutas de circulación de sal en la Provincia de Tunja contribuyeron a configurar un gran espacio económico, que integró a las provincias de Santa Fe, Pamplona y Tunja en el Nuevo Reino de Granada, durante el siglo XVI. Se partió de una reflexión historiográfica relacionada con la circulación y el comercio de la sal, los medios de transporte y las rutas usadas por los indígenas y los españoles; a partir de las cuales se consolidó un espacio económico mediado por la producción y distribución de la sal, que convirtió a la provincia de Tunja en un eje articulador de relaciones entre los sitios productores de sal en la provincia de Santa Fe y los consumidores de las provincias de Tunja y Pamplona. Esta articulación regional facilitó tanto la circulación de productos de distintos pisos térmicos, como la integración de un amplio territorio colonial. Esto debido a que la localización de Tunja como lugar de paso y conexión entre las Provincias de Santafé, Pamplona y los Llanos de San Juan, hizo de esta ciudad y sus términos un atractivo para el asentamiento hispano, a la vez que generó, durante la segunda mitad del siglo XVI, la posibilidad para que se organizaran en toda la Provincia de Tunja, sitios de aposento, venta y reventa de productos importados de España y productos de la tierra, para el sustento y abastecimiento de las necesidades básicas, y de esta forma sacar provecho de las producciones locales como la sal, el hayo, el algodón, las mantas y otros productos.

    Full Text Available Con el propósito de evaluar la participación de las bacterias heterotróficas en el flujo de carbono en la cadena trófica de un lago de inundación amazónico, colectas mensuales de estos microorganismos fueron realizadas durante el año hidrológico de diciembre de 2007 hasta noviembre de 2008, en las regiones litoral, pelágica y de macrófitas acuáticas del lago Catalão, en la Amazonia Central brasilera. Las bacterias fueron multiplicadas in vitro, usando como sustrato el carbono orgánico disuelto (COD del lago en cada una de las regiones estudiadas, para posterior análisis de la abundancia de isotopos estables de carbono y nitrógeno. Estos datos fueron confrontados con los valores de COD de los cuatro periodos limnológicos del lago (seca, inundación, llena y bajada de aguas. En general se encontró que la fuente principal de carbono de las bacterias heterotróficas fue aquella de origen C4, que presentó un aporte mínimo de 75%, en la medida en que el δ13C de las bacterias presentó valor medio de -17,72‰ ± 2,25. Confrontando ese valor, con el δ13C del zooplancton en el mismo período (-33,04‰±3,81 se concluye que el aporte de las bacterias heterotróficas al flujo de carbono hacia niveles tróficos superiores en el lago estudiado es mínimo.

  14. Assessment of the Regenerative Potential of Organic Waste Streams in Lagos Mega-City

    Opejin, Adenike Kafayat

    There is never a better time for this study than now when Nigeria as a country is going through the worst time in power supply. In Lagos city about 12,000 tons of waste is generated daily, and is expected to increase as the city adds more population. The management of these waste has generated great concern among professionals, academia and government agencies. This study examined the regenerative management of organic waste, which accounts for about 45% of the total waste generated in Lagos. To do this, two management scenarios were developed: landfill methane to electricity and compost; and analyzed using data collected during field work and from government reports. While it is understood that landfilling waste is the least sustainable option, this study argued that it could be a viable method for developing countries. Using U.S EPA LandGEM and the IPCC model, estimates of capturable landfill methane gas was derived for three landfills studied. Furthermore, a 35-year projection of waste and landfill methane was done for three newly proposed landfills. Assumptions were made that these new landfills will be sanitary. It was established that an average of 919,480,928m3 methane gas could be captured to generate an average of 9,687,176 MW of electricity annually. This makes it a significant source of power supply to a city that suffers from incessant power outages. Analysis of composting organics in Lagos was also done using descriptive method. Although, it could be argued that composting is the most regenerative way of managing organics, but it has some problems associated with it. Earthcare Compost Company processes an average of 600 tons of organics on a daily basis. The fraction of waste processed is infinitesimal compared to the rate of waste generated. One major issue identified in this study as an obstacle to extensive use of this method is the marketability of compost. The study therefore suggests that government should focus on getting the best out of the

    This descriptive study was carried out to assess the awareness and acceptability of Assisted Reproductive Technology (ART) among infertile women in Lagos, Nigeria. Self-administered questionnaires on the knowledge of ART in the women were used. After a brief exposé on ART, questions relating to their attitude were answered. A total of 166 women were studied. Only 51.8% had any knowledge of ART and most of these had poor knowledge. A total of 137 women would embrace ART if offered but 29 would not, for reasons such as religion, fear of side-effects, failure and unaffordable costs. There is a paucity of good knowledge of ART. A significant number of the women would consider ART if offered. There is thus a need to create more awareness about the possibilities offered by ART, as well as instituting low cost ART strategies in developing world countries.

    Lago Loíza is a reservoir formed at the confluence of Río Gurabo and Río Grande de Loíza in the municipality of Trujillo Alto in central Puerto Rico, about 10 kilometers (km) north of the town of Caguas, about 9 km northwest of Gurabo, and about 3 km south of Trujillo Alto (fig. 1). The Carraizo Dam is owned and operated by the Puerto Rico Aqueduct and Sewer Authority (PRASA), and was constructed in 1953 as a water-supply reservoir for the San Juan Metropolitan area. The dam is a concrete gravity structure that is located in a shallow valley and has a gently sloping left abutment and steep right abutment. Non-overflow sections flank the spillway section. Waterways include an intake structure for the pumping station and power plant, sluiceways, a trash sluice, and a spillway. The reservoir was built to provide a storage capacity of 26.8 million cubic meters (Mm3) of water at the maximum pool elevation of 41.14 meters (m) above mean sea level (msl) for the Sergio Cuevas Filtration Plant that serves the San Juan metropolitan area. The reservoir has a drainage area of 538 square kilometers (km2) and receives an annual mean rainfall that ranges from 1,600 to 5,000 millimeters per year (mm/yr). The principal streams that drain into Lago Loíza are the Río Grande de Loíza, Río Gurabo, and Río Cañas. Two other rivers, the Río Bairoa and Río Cagüitas, discharge into the Río Grande de Loíza just before it enters the reservoir. The combined mean annual runoff of the Río Grande de Loíza and the Río Gurabo for the 1960–2009 period of record is 323 Mm3. Flow from these streams constitutes about 89 percent of the total mean annual inflow of 364 Mm3 to the reservoir (U.S. Geological Survey, 2009). Detailed information about Lago Loíza reservoir structures, historical sediment accumulation, and a dredge conducted in 1999 are available in Soler-López and Gómez-Gómez (2005).

    Full Text Available El objetivo de este trabajo es analizar la evolución en el tiempo de las defunciones y de las causas de muerte por edad y sexo de la población galesa de Gaiman, provincia de Chubut, Argentina. Los datos fueron obtenidos de las Actas de Defunción del Archivo del Registro Civil de la ciudad de Rawson, Chubut. El período de estudio se extendió de 1892 a 1961 y para su descripción y análisis se lo dividió en decenios. Se registraron 2103 defunciones de las cuales 1039 (49% correspondieron a galeses y sus descendientes, lo cual representa un promedio de 14.6 muertes por año. Se detectó una sobremortalidad masculina (59%, esperable en una población colonizadora con predominio de varones. Se observó un incremento, en el tiempo, de la edad media de defunción, lo que indica mejoras en las condiciones socioeconómicas y de salud de la población. La mortalidad infantil y los natimortos representaron el 20% y el 11%, respectivamente, de las defunciones y se constató una transición desde una mortalidad provocada por enfermedades de naturaleza exógena a otra de causalidad endógena. Al compararse nuestros datos con los de la provincia de Chubut y el país, se comprobó, en todos los casos, un descenso de la mortalidad en el tiempo, aunque en Gaiman esa disminución fue más significativa, probablemente por la atención que la comunidad le dedicaba a la educación y a la salud.

    Precious metal-bearing quartz veins occur at the northeastern sector of the Lago Fontana region in southwestern Argentina, within the context of the Andean continental magmatic arc environment. The deposits and their associated alteration zones are spatially related to a Cretaceous calc-alkaline magmatism represented by silicic dikes and hypabyssal intrusions, and hosted by a Late Jurassic to Cretaceous volcano-sedimentary sequence. The veins and related veinlets crop out discontinuously, in general terms in a NW-SE belt. The primary vein mineral assemblage is composed mostly of pyrite ± galena ± chalcopyrite > hematite ± arsenopyrite in silica gangue minerals. Chemical analyses of grab samples from selected quartz veins show as much as 5.7 ppm Au and 224 ppm Ag, as well as elevated Pb, Cu, and Zn. Hydrothermal fluids caused an innermost silicification and adularia-sericite alteration assemblage, and an external propylitic halo. Sulfur isotope values measured for sulfides (δSS from -1.90 to +1.56‰), and oxygen and hydrogen isotopes measured on quartz crystals and extracted primary fluid inclusion waters (δOO = -2.85 to +5.40‰; δDO = -106.0 to -103.4‰) indicate that mineralization probably formed from magmatic fluids, which were mixed with meteoric waters. Also, fluid inclusion data from quartz veins point out that these fluids had low salinity (1.7-4.2 wt% NaCl equiv.), and temperatures of homogenization between 180 and 325 °C. Mineralogical, petrographic and geochemical features for mineralized surface exposures indicate a typical adularia-sericite, low sulfidation epithermal system in the Lago Fontana area that represents a promising target for further exploration programs.

    Full Text Available Regional cluster, a geographically bounded concentration of interdependent firms, is the best environment to fostering a strong relationship amongst firms which can lead to amazing technological and industrial expansion. This paper underscores clustering and the resultant nature of relationship amongst firms, using the Lagos region as a case study. One hundred and three questionnaire were administered in twelve industrial estates; one questionnaire in each of the firm. This connotes that all the firms in the industrial estates were successfully covered in the questionnaire administration, which was administered. A descriptive statistical analytical technique was adopted. The paper has reveals the types of working relationship amongst firms in the Lagos region which includes; raw materials purchase, subcontract, collaboration in research and development, sales promotion, transportation, power supply, water supply, security, waste treatment, telecommunication, ports and shipping as well as labour supply. The paper found out that raw materials purchase/supply was more striking amongst the working relationship types. Also, the paper has revealed services sharing amongst the firms and transport as the most dominant. The most important location advantage was the market facilities. The analysis of variance carried out in relation to variation in clustering amongst the firms at 0.05% level was significant. The paper concluded that industrial cluster if encouraged, will lead to increase working relationship, which in turn have the capability of boosting, promoting and encouraging economies of clustering. Cluster concepts spatially emphasize inter-firm relations that facilitate innovative activity, which is recognized as a driving force of sustained economic growth. It is therefore recommended that these clustering of firms should be made viable, encouraged and strengthened through government investment in the industrial sector, making the location

    Contraception means procedures employed to interfere at one stage or the other with the normal sequence of events in the process of reproduction leading to a failure in conception. It means voluntary techniques adopted to achieve birth control. Its use remains sensitive worldwide. Within the same society, contraception varies amongst people of different socio-cultural, educational, religious, or occupational affiliations. It also varies between urban and rural settlements. Some contraceptive techniques also prevent sexually transmitted infections (STIs). The prevalence of STIs also varies with these same factors. There is very limited literature on contraception exclusively amongst bankers. We sought to investigate the level of awareness and practice of contraception amongst bankers in an urban society in Lagos State, Nigeria. In this descriptive cross-sectional study, 200 self-administered structured questionnaires were retrieved from bankers from 5 banks selected by simple random sampling in Surulere Local Government Area of Lagos State, Nigeria. Data was subsequently statistically analyzed using SPSS. The age range was 21-45 years, mean 28.8±1.4 years, 51.7% were males (72% single, 27% married, 1% separated) and 48.3% were females (52.4% single, 47.6% married). All (100%) respondents were aware of contraception, 93.3% males and 91.7% females were sexually active, 88.9% males and 84.5% females believe contraception is useful. Most (71.4%) respondents practice contraception, males (81%) being more than females (61.1%), p males believe that contraception prevents pregnancy but not STIs, 28.6% of females and 46.6% of males believe it prevents both pregnancy and STIs, whereas 14% of males and no female believe contraception prevents STIs but not pregnancy. The awareness of and practice of contraception was very high among the bankers but more male bankers practice contraception whereas more female bankers perceive contraceptives to be for the married only.

    Full Text Available The differences in construction methods between different forms of slabs construction tend to result into variation in the cost of the slabs for any building project. Thus, this study aims at assessing the variation in construction cost among various construction methods available for hollow and solid floors in construction projects within Lagos State. The research design for this study was a survey design approach and the population of the study are active professionals (Architects, Civil Engineers, Builders, Quantity Surveyors, Consultant and contractors because they are the major participants in the construction activities of the construction industry in Lagos State, Nigeria. The research is based on 46 returned questionnaires out of the 60 that was administered. The data from the questionnaires were analyzed using descriptive tools such as frequencies, percentage and mean values. The hypotheses were tested with paired sample t-test and it was found that the system or method of slab construction well known to the respondents is cast in situ, precast and semi-precast. The study also shows that the cost of in-situ solid slabs are higher than that of hollow slab which is an indication that solid slab construction is more expensive than hollow slab construction provided the hollow slab is a one-way hollow floor and not waffle floor. In pre cast solid slab construction the cost of transportation of units to sites, cost of expertise required in the construction process and the cost of fabrication off site are the three highest and most expensive aspects of precast solid slab while cost of erection and placement and the cost of grouting and topping if required are less expensive. Therefore there is difference in the cost of construction between the solid and hollow slabs but the difference is not appreciable. The study's major recommendation is that, adequate and careful analysis must be done in the choice of floor system being adopted for any

    Full Text Available INTRODUCTION: Toxoplasma gondii infection has been described as the most widespread zoonotic infection of humans and other animals. Information concerning T. gondii infection among schoolchildren is unavailable in Lagos City, Nigeria. METHODS: This cross-sectional study investigated the seroprevalence and risk factors associated with T. gondii infection among primary schoolchildren (PSC from a community located in the center of Lagos, southern Nigeria, from November 2013 to March 2014. A total of 382 PSC were screened for the presence of sera anti-T. gondii antibodies using a latex agglutination test (TOXO Test-MT, Tokyo, Japan. A cutoff titer of ≥ 1:32 was considered positive, while titers ≥ 1:1,024 indicated high responders. Questionnaires were also used to obtain data on possible risk factors from parents/guardians. RESULTS: The overall seroprevalence was 24% (91/382, and 83.5% (76/91 of seropositive PSC were classified as high responders. Among the risk factors tested, including contact with cats and soil, consumption of raw meat and vegetables, and drinking unboiled water, none showed statistical significance after multivariate adjustment. No associations were observed among age, gender, body mass index (BMI, and parents' occupation/educational level. CONCLUSIONS: The findings in this study show evidence of active infection, and hence, there is need for urgent preventive measures in this city. Further investigation is required to clarify the transmission routes. Policy makers also need to initiate prevention and control programs to protect pregnant women and immunocompromised patients in particular because they are more severely affected by T. gondii infection.

  20. Evaluation of Energy Use in Public Housing in Lagos, Nigeria: Prospects for Renewable Energy Sources

    Full Text Available Even though domestic energy can be from either renewable or non-renewable sources, the former is preferred because of its role in reducing both the operational energy intensity and carbon footprint. Given the positive role renewable energy plays in the energy mix, this paper examined the pattern of operational energy use with particular reference to the renewable and non-renewable energy content in medium and high density public residential buildings in Lagos, Nigeria. A survey research method was adopted for primary data collection while data analysis was by descriptive statistics. The study found that renewable energy use in the residential units is very low. In contrast, there was high dependence of the occupants on non-renewable direct fuel combustion through the use of fossil fuel-driven privately-owned electricity generators for electricity supply as a result of the inadequate supply from the national grid. In addition to the relatively high operational energy intensity observed in the studied buildings, the findings have implications for the safety, health and wellbeing of the building occupants as well as for carbon emissions from the buildings and for overall environmental sustainability. Recommendations to increase renewable energy use in new buildings and as retrofits in existing buildings were made.

    Complete and accurate pathology reporting of colorectal carcinoma (CRC) resection specimen is critical to clinical management of individual patients. The study aims to audit colorectal cancer histopathology reporting in Lagos between 2011 and 2015 before the adoption of the Society for Gastroenterology and Hepatology in Nigeria pro forma in 2016. All resected CRC cases were identified from the Histopathology record of our Department and that of a private Laboratory in Lagos over a 5-year from 2011 to 2015. The dataset as contained in the pro forma was extracted from the reports and analysed using SPSS version 16 software. A total of 92 colorectal resections were received during the 5-year period consisting of 90 colonic and 2 rectal tumours. Data inclusiveness on tumour differentiation, extent of primary tumour, total lymph node and lymph node involvement were 96.7%, 91.3%, 83.7% and 92.4%, respectively. Tumour perforation, level of venous involvement and distant metastasis were reported in 73.9%, 21.7% and 96.7% respectively. The circumferential resection margin (CRM) in the 2 rectal tumours had 100% inclusiveness. Tumour node metastasis staging was complete in 87% of cases while Dukes staging was documented in 8.7% of the reports. None of the data items was 100% complete except the CRM for rectal carcinoma. Free text reporting results in incomplete data resulting in improper staging, especially the lymph node status. This highlights the need for pro forma reporting to ensure and maintain consistent reporting of important parameters required for proper staging and management of patients with colorectal cancer.

    Science outreach and engagement are crucial core objectives of the Lagos Ciência Viva Science Centre (CCVL). By engaging audiences in the real world a link is made between their science centre experience and the environment in which they live. Therefore, it has been an option of the CCVL to offer geological outdoor activities, both in the natural environment and urban context. Dinosaurs are an appealing science subject for both students and tourists. Thus, the CCVL has a long tradition in organizing and guiding field trips to two dinosaur track sites - Salema and Santa beaches (Vila do Bispo, southwest Algarve). These sites, both from the Lower Cretaceous reveal at least two types of tracks - theropod and iguanodontian footprints. Often in combination with the paleontology field trips, the CCVL also offers different geological field trips both for formal (school) and informal (tourism) education. This allows students and tourists to be introduced to dinosaur paleobiology and ichnology and to the structural geology and stratigraphy of the area. Our science outreach is being further developed by contractual agreement with a regional tour operator, in which the CCVL is responsible for the scientific content and guidance of the visits. Aiming at an urban context, the CCVL produced three Urban Geology and Paleontology Guide Books for three Algarve cities (Lagos, Faro and Tavira), which can be acquired in the three Ciência Viva Science Centres shops as well as in the tourist information offices serving this way as a basis for guided urban tours also offered by the CCVL. Based on our experience, we review and contextualise these geoscience activities and their potential for science outreach, communication and tourism. We discuss and propose a classification of different possibilities in geoscience communication and outreach based on three vertices: Science, Heritage and Geotourism. Some particularities of these visits, such as the merge between geosciences and other

    Full Text Available The need for comprehensive air pollution studies in Lagos cannot be overemphasized in view of the level of industrialization of the city and its nearness to the ocean. Air particulate samples collected with a high-volume air sampler at three locations in Lagos, Nigeria were analyzed by the combination of wavelength-dispersive X-ray fluorescence and atomic absorption spectroscopy methods. Elemental concentrations were subjected to factor analysis for source identification and chemical mass balance model was used for source apportionment. Prominent among sources identified with the ranges of their contributions at the sites are: soil 35-54%, marine 26-34%, automobile exhaust 0.3-3.5%, refuse incineration 2-3%, and regional sulphate 2-12%.

  7. Testing freshwater Lago Mare dispersal theory on the phylogeny relationships of iberian cyprinid genera Chondrostoma and Squalius (Cypriniformes, Cyprinidae

    Carmona, José Ambrosio

    2003-12-01

    Full Text Available A phylogeny of the species in the genera Chondrostoma and Squalius was constructed based on the complete mitochondrial cytochrome b gene (1140pb. The molecular phylogeny was used to test the effect of the Mediterranean Lago Mare dispersal theory on the processes of divergence and speciation of European freshwater fishes. Phylogenetic relationships among Squalius samples and the molecular clock revealed that the ancestor of the current Iberian Squalius species inhabited a wide geographic area in the central and southwestern part of the former Iberian Peninsula during the Miocene before the Lago Mare phase. Similarly, the four main Iberian lineages of the genus Chondrostoma originated in the Middle-Upper Miocene. Hence, the Lago Mare phase of the Mediterranean Sea seems to have been a too recent paleogeographic event to have had any major impact on the dispersion of Squalius and Chondrostoma species. However, the reduction of the water-bodies during the Tortonian and Messinian may have intensified the isolation of populations. The Operational Biogeographic Units recovered from the Squalius and Chondrostoma phylogenies also reject the Lago Mare dispersal theory and support the idea that the differentiation processes were due to both the formation of the current hydrographical basin during the Plio-Pleistocene as well as to an earlier endorrheism event that occurred prior to hydrographical configuration.Realizamos una filogenia de los géneros Chondrostoma y Squalius mediante el estudio de la secuencia completa del gen mitocondrial citocromo b (1140pb. La filogenia molecular fue usada para comprobar el efecto que la teoría de dispersión del Mediterráneo Lago Mare ha tenido sobre los procesos de divergencia y especiación en los peces de agua dulce europeos. Las relaciones filogenéticas entre las muestras de Squalius y la aplicación del reloj molecular pusieron de manifiesto que el ancestro de las actuales especies ibéricas de Squalius habitaba

    We evaluated the spatial and temporal variation in communities of dragonfly's naiads and their association to the habitat rehabilitation status in La Vaca and Santa Maria del Lago wetlands. Four samplings were carried out in several sites of each during a year. Macroinvertebrates were collected at the entry and exit flow, and in open waters of the wetlands using standard techniques. We found a gradient in the distribution of the abundance of nymphs in both wetlands, where naiads community had the highest number of individuals in the places located farther from the dumping sites. Comparing the community s composition between wetlands La Vaca and Santa Maria del Lago through the beta diversity, heterogeneity was found in both ecosystems. The gradient in the distribution of the abundance of naiads observed in both wetlands fits with to a response of the species in terms of tolerance to the environmental variables.

    Several toxicological studies into the effects of aquatic pollutants on the liver of teleost fish exist in literature. The focus on the liver in these studies is predicated on its central nature in the scheme of biotransformation and excretion of xenobiotics following exposure in polluted water bodies. As a consequence of the latter primary role of the liver in these processes it is regarded as a predilective site for the sub lethal effects of xenobiotics on the organism usually detectable at histological level. Hepatic histopathology recorded in livers from feral populations of the brackish water catfish Chrysichthys nigrodigitatus from locations on the Lagos lagoon complex with significant anthropogenic inputs from denizen populations and industries are presented. Liver sections from sixty specimens from two locations on the Lagos lagoon complex (Badagry lagoon: 6??24'N, 2??56'E; and Lagos lagoon: 6??29'N, 3??22'E) were analysed. Observed pathologies included hydropic degeneration (58%), portal / sinusoidal congestion (33%), hepatic necrosis (26%), hemosiderosis (12%) and foci of cellular alterations (FCA's). No obvious oncologic features were observed; the presence of the hydropic Vacuolation lesion was taken as prelude to the development of neoplasms and discussed as such. ?? 2009, Penkala Bt., Budapest, Hungary.

    Full Text Available Studies have shown that the quality of outcome in Nigerian secondary schools is declining at an alarming rate due to shortage of required resources as well as leadership challenges. The challenges have been observed to be as a result of lack of mentoring which is not a common practice in school management in Nigeria. Consequently, this study investigated the extent to which mentoring as a strategy for administrators' succession plan impacts on the performance of their duties in public and private secondary schools in Lagos, Nigeria. The study adopted the descriptive survey design and administered a 25-item self-constructed questionnaire on participants. A total of 530 participants were randomly selected from the population of 4,350 senior teachers. The Participants were drawn from 145 secondary schools (91 public and 54 registered private in Education District IV of Lagos State. The findings showed that mentoring has significant impact on administrators' succession planning and that succession planning does not significantly differ in public and private secondary schools in Lagos State. The study concluded that leadership development is a critical factor in secondary school effectiveness and efficiency. Therefore, serving administrators as well as prospective administrators should be regularly evaluated to determine their training needs at different career stages. There should also be mentoring related policies to enhance the managerial skills, sense of competence and effectiveness of the prospective administrators.

    Preterm birth is a dire complication of pregnancy that poses huge long-term medical and financial burdens for affected children, their families, and the health care system. The aim of the present study was to identify characteristics associated with preterm births at the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria from 2011 to 2013. We obtained Information from 5,561 maternal, fetal/neonatal and obstetric records from the labor ward. We excluded delivery at less than 22 weeks (0.25%), post-term birth at ≥42 weeks gestation (1.3%), and unknown gestation (1.4%). Additionally, we excluded records of multiple births (5.4%) and stillbirths (8.3%) leaving 4,691 records of singleton live-births for analysis. Logistic regression analysis was performed comparing preterm birth (22-36 weeks gestation) to term birth (37-41 weeks gestation). Multiple variable models adjusting for maternal age, parity, fetal position, delivery method and booking status were also evaluated. Multinomial regression was used to identify characteristics associated with preterm birth (PTB) defined as early PTB (22-31 weeks gestation), moderate PTB (32-34 weeks gestation), late PTB (35-36 weeks gestation), compared to term birth (37-41 completed weeks gestation). From our data, 16.8% of the singleton live-birth deliveries were preterm (PTBs. Older maternal age (≥35 years) [odds ratio (OR) = 1.41], hypertension (OR = 3.44) and rupture of membranes (OR = 4.03) were significantly associated with increased odds of PTB. Women being treated for the prevention of mother-to-child transmission of HIV were at a significantly decreased risk for PTB (OR = 0.70). Sixteen percent of women in this cohort were not registered for antenatal care in LUTH. These non-registered subjects had significantly greater odds of all categories of PTB, including early (odds ratio (OR) = 20.8), moderate (OR = 8.68), and late (OR = 2.15). PTB and risks for PTB remain high in Nigeria. We recommend that any high risk

    During more than a decade Gamma Ray Bursts (GRB a cosmological phenomena of tremendous power) have been extensively studied in the keV - MeV energy range. However, the higher energy emission still remains a mystery. The Large Aperture GRB Observatory (L.A.G.O.) is an international collaboration started in 2005 aiming at a better understanding of the GRB by studying their emission at high energies (> 1 GeV), where the fluxes are low and measurements by satellites are difficult. This is done using the Single Particle Technique, by means of ground-based Water Cherenkov Detectors (WCD) at sites of high altitude. At those altitudes it is possible to detect air showers produced by high energy photons from the GRB, i. e. a higher rate of events on a short time scale, of the order of the second. The Pierre Auger Observatory could detect such GRB given its large number of detectors, but at 1400 m.a.s.l. the expected signal is quite small. At higher altitudes, similar performance is expected with only a very small number of WCD. As of 2011, high altitude WCD are in operation at Sierra Negra (Mexico, 4650 m.a.s.l.), Chacaltaya (Bolivia, 5200 m.a.s.l.), Maracapomacocha (Peru, 4200 m.a.s.l.), and new WCDs are being installed in Venezuela (Pico Espejo, 4750 m.a.s.l.), Argentina, Brazil, Chile, Colombia and Guatemala. Most of the new WCDs will not be at high enough altitude to detect GRB, never the less it will allow obtaining valuable measurements of secondaries at ground level, which are relevant for solar physics. The LAGO sensitivity to GRB is determined from simulations (under a sudden increase of 1 GeV - 1 TeV photons from a GRB) of the gamma initiated particle shower in the atmosphere and the WCD response to secondaries. We report on WDC calibration and operation at high altitude, GRB detectability, background rates, search for bursts in several months of preliminary data, as well as search for signals at ground level when satellite burst is reported, all these show the

    Full Text Available BACKGROUND: Microsporidia are obligate intracellular parasites that infect a broad range of vertebrates and invertebrates. They have been increasingly recognized as human pathogens in AIDS patients, mainly associated with a life-threatening chronic diarrhea and systemic disease. However, to date the global epidemiology of human microsporidiosis is poorly understood, and recent data suggest that the incidence of these pathogens is much higher than previously reported and may represent a neglected etiological agent of more common diseases indeed in immunocompetent individuals. To contribute to the knowledge of microsporidia molecular epidemiology in HIV-positive patients in Nigeria, the authors tested stool samples proceeding from patients with and without diarrhea. METHODOLOGY/PRINCIPAL FINDINGS: Stool samples from 193 HIV-positive patients with and without diarrhea (67 and 126 respectively from Lagos (Nigeria were investigated for the presence of microsporidia and Cryptosporidium using Weber's Chromotrope-based stain, Kinyoun stain, IFAT and PCR. The Weber stain showed 45 fecal samples (23.3% with characteristic microsporidia spores, and a significant association of microsporidia with diarrhea was observed (O.R. = 18.2; CI: 95%. A similar result was obtained using Kinyoun stain, showing 44 (31,8% positive samples with structures morphologically compatible with Cryptosporidium sp, 14 (31.8% of them with infection mixed with microsporidia. The characterization of microsporidia species by IFAT and PCR allowed identification of Enterocytozoon bieneusi, Encephalitozoon intestinalis and E. cuniculi in 5, 2 and 1 samples respectively. The partial sequencing of the ITS region of the rRNA genes showed that the three isolates of E.bieneusi studied are included in Group I, one of which bears the genotype B. CONCLUSIONS/SIGNIFICANCE: To our knowledge, this is the first report of microsporidia characterization in fecal samples from HIV-positive patients from

    A major share of the hospital budget is spent on drugs. Irrational use of these drugs is a waste of financial and human resources that could have been deployed for another use within the hospital setting especially in cases where such drugs are provided free to patients. Also there is increased morbidity and progression of severity with irrational use. The objective of this study was to determine the irrational use of chloroquine and the subsequent cost implications in Lagos State general hospitals. A retrospective study period of one year (January to December, 2000) was selected. A total of 18,781 prescription forms of "Free Eko Malaria" were sampled for children and adults from all the Lagos State general hospitals. Drug costs in each prescription form were identified. Cost effectiveness analysis of chloroquine tablet and intramuscular injection was undertaken. The average cost of medicine per prescription was 132.071 ($1.03) which should have been 94.22 ($0.73) if prescribed rationally. The total cost of prescriptions for malaria under study was 2,480,425.00 ($19,348.09). About 68% {(1,679,444.00) ($13,100.19)} of the total cost was lost to irrational prescribing. This is a waste of scarce resources. When the prescriptions were differentiated into the different dosage forms prescribed, the prescriptions containing intramuscular injections only had over 90% of the cost lost to irrational prescribing. Cost effectiveness analysis showed that chloroquine tablet was 17 times more cost effective than chloroquine injection (intramuscular) from a health care system perspective while it was 14 times more cost effective from a patient perspective. There is waste of scarce resources with irrational dispensing of drugs and these resources could have been deployed to other uses or areas within the hospitals. The tablet chloroquine was more cost effective than injection chloroquine (intramuscular). Increasing the cost of tablets, decreasing effectiveness of tablets

    The global system mobile telecommunications system (GSM) which was recently introduced in Nigeria is now being used by over 40 million people in Nigeria. The use of GSM is accompanied with exposure of the users to radiofrequency radiation (RFR), which if significant, may produce health hazards. This is the reason why many relevant national and international organizations recommended exposure limits to RFR and why it is made compulsory for GSM handsets to indicate the maximum power output as a guide to potential consumers. This study was conducted to measure the RFR output power densities (S) from the most commonly used GSM handsets used in Lagos State and compare with the limit recommended for safety assessment. Over 1100 most commonly used handsets of different makes and models as well as wireless phones were sampled and studied in all over the local government areas of the State. An RFR meter, Electrosmog from LESSEMF USA was used for the measurements. The handsets were assessed for health risks using the reference value of 9 Wm(-2) as recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The range of the S-values obtained varied from a minimum of 1.294 0.101 Wm(-2) with Siemens model R228 to a maximum of 16.813 +/- 0.094 Wm(-2) with Samsung model C140*. The results from wireless telephones showed very low S-values ranging from a minimum of 0.024 +/- 0.001 Wm(-2) with HUAWEI and ST CDMA 1 to a maximum of 0.093 +/- 0.002 Wm(-2) with HISENSE. The results showed that the population in Lagos State may be at risk due to significant RFR exposures resulting principally from the use of GSM. Quite a number of handsets emit power above the ICNIRP recommended value. Measured RFR power close to Radio and Television masts and transmitters are within tolerable limits in most cases, only that the public should not reside or work close to RFR installations. Phone calls with GSM should be restricted to essential ones while youths and children

Se presenta un análisis de entrevistas con diferentes actores abocados al desarrollado de intervenciones frente a las mujeres madres encarceladas con sus hijos/as en la Unidad N°33 de la localidad de Los Hornos, en la provincia de Buenos Aires. El ejercicio del cuidado en el caso de las mujeres encarceladas, cumple una función doble, por un lado el control informal (Gentile & Tabbush, 2013 del sistema patriarcal que asigna de manera obligatoria el ejercicio del mismo por parte de las mujeres, aún en el caso de las mujeres madres detenidas. Por otro lado, en función de las características del aumento de prisionización de las mujeres por delitos de tenencia de estupefacientes, se indaga de estas en la economía ilegal, y se intenta establecer algunas reflexiones sobre el mencionado delito y la posibilidad de conciliar estrategias de supervivencia económica y cuidado.

    Full Text Available La configuración del Estado argentino hacia fines del siglo XIX y principios del XX tuvo como uno de sus móviles principales la eliminación, asimilación e invisibilización de los pueblos indígenas. En las últimas décadas del siglo XX, se ha pasado de una política de invisibilización y homogeneización a otra de visibilización y reconocimiento de la diversidad cultural, promoviéndose la diversidad territorial, cultural y lingüística acallada durante décadas. El objetivo del presente artículo es indagar en las características asumidas por estos procesos en la provincia de Salta. Partiendo de considerar al Chaco salteño como territorio históricamente imaginado como indígena, interesa pensar cómo juegan estos imaginarios territoriales a la hora de diseñar e implementar políticas públicas para este territorio y su población.

    Full Text Available El presente trabajo se desarrolló en el oeste de la provincia de Buenos Aires, Argentina con el objetivo de ajustar funciones de biomasa de árboles individuales y determinar la biomasa en diferentes compartimientos de la planta y el sotobosque. Se identificaron rodales de Eucalyptus viminalis Labill. cuyas edades oscilaron entre 4 y 14 años. Se apearon 21 árboles con diámetros entre 9,2 y 32,5 cm. Se desarrollaron regresiones simples y múltiples y se estimó el volumen, la biomasa en ramas, hojas y fuste. Las ecuaciones de volumen de mejor comportamiento son basadas en modelos lineales en su forma normal, y el modelo más adecuado fue el que incorporó al d2 (R2 = 0,92. Para la estimación de la biomasa en hojas, ramas, copa y fuste se recomienda los modelos ln-ln que consideran el d y h o solo el d. El componente de la biomasa en hojas presentó una estimación más débil. La distribución de la biomasa en los individuos sigue el patrón de desarrollo que se encuentra en la bibliografía. La proporción de la biomasa en la copa disminuye con la edad, contrariamente a lo sucedido con el fuste.

    Full Text Available Durante el siglo XIX y en los albores del XX, la escritura de cartas fue el medio más difundido para establecer comunicación con personas a la distancia, pese a lo cual, cuando hablamos de la escritura epistolar de entonces, tendemos a pensar en mujeres de la élite que tenían acceso a cierta educación. Sin embargo, existen indicios de que escribir cartas era también una práctica de la clase trabajadora, como lo demuestra el caso de Rosa, la protagonista de la historia que nos proponemos contar aquí. De este modo, el presente artículo se basa en un corpus documental que implica un desafío: partir de un conjunto de cartas de amor producidas por una mujer trabajadora, buscando por su intermedio adentrarnos en una relación entre dos personas y avanzar al mismo tiempo en otras direcciones. Pretendemos  ir más allá de esa dimensión y de la vida privada para estar atentas a las concepciones y experiencias en torno al noviazgo y el matrimonio. En síntesis, buscamos, a través de Rosa, una mujer de la clase trabajadora del interior de la provincia de Buenos Aires, pensar en el amor como experiencia.

    We investigated food hygiene-related behaviour as well as other risk factors for diarrhoea in children 6-36 months of age in Iwaya community in Lagos, Nigeria. Between April and July 1989, a bi-weekly diarrhoea surveillance was maintained in 672 households. Following the surveillance, 273 (case = 67 and control = 206) families were visited twice, each visit lasting for 3-4 hours. Detailed observations on food hygiene, water sanitation, and sanitary conditions of the home were made. There was no significant association between any of the observed food hygiene behaviours and the occurrence of diarrhoea. The presence of faeces in and around the toilet area (RR = 1.79), habit of defecating and urinating in chamber pots in dwelling units (RR = 1.80), indiscriminate disposal of waste (RR = 2.48), and source of domestic water (RR = 2.94) were the main factors significantly associated with the occurrence of diarrhoea in this community. These findings imply that diarrhoea might be reduced through an education programme which focuses on the proper care, handling and storage of defecation pots and proper disposal of waste.

  7. Mechanisms of hypolimnion erosion in a deep lake (Lago Maggiore, N. Italy

    2010-02-01

    Full Text Available Holo-oligomixis is one of the most important hydrodynamic characteristics of deep lakes in temperate regions, especially those of the Southern Alps. It influences such important lake chemical and biological processes as the oxygenation of deep layers, recycling of nutrients, vertical migration of plankton, and reproduction. Analysis of physico-chemical data from Lago Maggiore over the years 1951 – 2008 has shown that in addition to ever active but relatively inefficient convective mixing, three other mechanisms act to oxygenate this lake’s deep waters in winter. These are conveyor belt currents, cold and well-oxygenated tributary inflows that sink down to depths of equal density, and differential cooling of littoral waters that subsequently slide down the lake flanks. Their common outcome is to cause deep erosion of the hypolimnion. Heat content and thermal stability also are affected and are analyzed here in relation to external driving forces, examining in particular how dynamics may be altered by climate change.

    We studied 116 patients who presented with cleft lip and palate (CLP) and were seen during a state-wide screening exercise for people with orofacial deformities in Ikeja-Lagos, Nigeria between May 2006 and July 2007. Detailed histories were taken and physical examinations made. The following psychometric instruments: General Health Questionnaire 28 (GHQ28), State-Trait Anxiety Inventory Y1 (STAI-Y1), STAI-Y2, and Self rating Depression Scale (SDS) were given on the respondents by a clinical psychologist. The respondents comprised 57 men and 59 women with a male:female ratio of 1:1.04. There were 42 (36%) adults and 74 (64%) children. Fifty-four (47%) patients had cleft lip (CL), 27 (23%) had cleft lip and palate (CLP), and 35 (30%) had cleft palate alone. Forty-five (39%) of the respondents were parents and guardians who responded to the presence of the deformity on behalf of children who were less than 6 years old, and assessed the reactions of those who were aged 6-12 years old. Older patients replied directly to the psychometric instruments. The outcome of the assessment of the Mental Health Profile of the participants showed high incidence of anxiety, depression, and impairment of general wellbeing. The effects were most pronounced in the 6-12 year age group. We recommend that the psychosocial impacts of CLP on the patients, parents, and relations should be managed together with the reconstructive procedures.

    Service quality assessments have assumed increasing importance in the last two decades. They are useful in identifying gaps in services been provided with the ultimate aim of guaranteeing quality assurance. The objective of this study was to assess the client perception of service quality at the outpatient clinics of Randle General hospital, Lagos. A descriptive cross sectional study was conducted from March to May 2013. A multistage sampling technique was used to select respondents and data was collected with the aid of modified SERVQUAL questionnaires. The data was analysed with aid of EPI-INFO 2002 and statistical significance was set at a P value 0.05 for statistical significance. Total of 400 respondents were interviewed. The mean age was 40 years with a standard deviation of 15.2 yrs. The highest mean score of 4.35 out of a possible maximum of 5 was recorded in assurance domain while the lowest mean score of 4.00 was recorded in the responsiveness domain. The overall mean score of all the domains was 4.20 with standard deviation of 0.51. Overall majority (80.8%) of respondents rated the overall service quality as good/ very good. After linear regression, the assurance domain was the most important predictor of the overall perceived service quality (pservice quality was good. The major deficiencies were in the responsiveness domain and especially the waiting time. The hospital management should implement measures to improve the responsiveness of services by ensuring prompt delivery of services.

    Ground water from Regiao dos Lagos, a coastal area of Rio de Janeiro state, was analysed for 226 Ra, 228 Ra, 222 Rn, 238 U, major ion concentrations, and physico-chemical parameters were also measured. Concentrations values ranged from -1 for 226 Ra, from -1 for 228 Ra and from -4 to 8.0x10 -2 Bq l -1 for 238 U. Detectable 222 Rn concentrations (>3 Bq l -1 ) were found only in two samples. The spatial distribution of Ra concentration delineated one distinct area and some hot spots with high Ra concentration. Low pH value is the most important water parameter linked to high radium concentration. This is probably related to limited adsorption of radium on soil ferric oxides and hydroxides at low pH range. There was a significant correlation between uranium concentrations and electrical conductivity values, and also between uranium concentrations and concentrations of Ca, Mg, Na, K, and Cl, indicating sea water impact. Uranium concentrations were lower than maximum contaminant level for drinking water, whereas 17 out of the 88 ground water samples had levels of radium that exceeded the maximum contaminant level for tap water. The total annual effective dose for adult due to the water consumption reaches values up to 0.8 mSv

    The manufacture of paint involves a variety of processes that present with medical hazards. Safety initiatives are hence introduced to limit hazard exposures and promote workplace safety. This aim of this study is to assess the use of available control measures/initiatives in selected paint factories in Lagos West Senatorial District, Nigeria. A total of 400 randomly selected paint factory workers were involved in the study. A well-structured World Health Organization standard questionnaire was designed and distributed to the workers to elicit information on awareness to occupational hazards, use of personal protective devices, and commonly experienced adverse symptoms. Urine samples were obtained from 50 workers randomly selected from these 400 participants, and the concentrations of the heavy metals (lead, cadmium, arsenic, and chromium) were determined using atomic absorption spectroscopy. The results show that 72.5% of the respondents are aware of the hazards associated with their jobs; 30% have had formal training on hazards and safety measures; 40% do not use personal protective devices, and 90% of the respondents reported symptoms relating to hazard exposure. There was a statistically significant (p metal concentrations in the urine samples obtained from paint factory workers as compared with nonfactory workers. The need to develop effective frameworks that will initiate the integration and ensure implementation of safety regulations in paint factories is evident. Where these exist, there is a need to promote adherence to these practice guidelines.

    Road traffic injuries have persisted as a serious public health problem and much of the health burden is in developing countries. Over-speeding, poor enforcement of traffic regulations and commuter buses have been highly implicated in road traffic injuries in developing countries. The aim of this study was to determine drivers' knowledge of selected road safety measures, i.e. the pre-requisites for driver's license, road signs and speed limits. This was a cross-sectional study carried out in Lagos, Nigeria. Simple random sampling was used to select the two motor parks used for the study and all the consenting commercial minibus drivers operating within the parks (407) were included in the study. Data was collected with a pre-tested, structured, interviewer-administered questionnaire and analyzed with epi-info statistical software. Two hundred and sixty-one (64.1%) of them knew that Visual Acuity test should be done before obtaining driver's license and 53.8% knew the correct minimum age for obtaining driver's license. Only 1% of the drivers had correct knowledge of the driver's license authorities in Nigeria. The drivers had poor knowledge of road signs (59.0%) and poor knowledge of maximum speed limits (100%). The oldest, least educated and least experienced drivers had the poorest level of knowledge. The drivers demonstrated poor knowledge of road safety measures. There is need for driver education to improve their knowledge.

    Emergency contraception can play an important role in reducing the rate of unintended pregnancies in Nigeria. Although it is included in the national family planning guidelines, there is limited awareness of this method among clients. In 2003-2004, a sample of 256 health care providers within Lagos State were surveyed about their knowledge of, attitudes toward and provision of emergency contraceptives, using a 25-item, self-administered questionnaire. Frequencies were calculated for the various measures, and chi-square tests were used to determine significant differences. Nine in 10 providers had heard of emergency contraception, but many lacked specific knowledge about the method. Only half of them knew the correct time frame for effective use of emergency contraceptive pills, and three-fourths knew that the pills prevent pregnancy; more than a third incorrectly believed that they may act as an abortifacient. Fewer than a third of respondents who had heard of the pills knew that they are legal in Nigeria. Of those who had heard about emergency contraception, 58% had provided clients with emergency contraceptive pills, yet only 10% of these providers could correctly identify the drug, dose and timing of the first pill in the regimen. Furthermore, fewer than one in 10 of those who knew of emergency contraception said they always provided information to clients, whereas a fourth said they never did so. Nigerian health care providers urgently need education about emergency contraception; training programs should target the types of providers who are less knowledgeable about the method.

    Waste characterization is the first step to any successful waste management policy. In this paper, the characterization and the trend of solid waste generated in University of Lagos, Nigeria was carried out using ASTM D5231-92 and Resource Conservation Reservation Authority RCRA Waste Sampling Draft Technical Guidance methods. The recyclable potential of the waste is very high constituting about 75% of the total waste generated. The estimated average daily solid waste generation in Unilag Akoka campus was estimated to be 32.2tons. The solid waste characterization was found to be: polythene bags 24% (7.73tons/day), paper 15% (4.83tons/day), organic matters 15%, (4.83tons/day), plastic 9% (2.90tons/day), inert materials 8% (2.58tons/day), sanitary 7% (2.25tons/day), textile 7% (2.25tons/day), others 6% (1.93tons/day), leather 4% (1.29tons/day) metals 3% (0.97tons/day), glass 2% (0.64tons/day) and e-waste 0% (0.0tons/day). The volume and distribution of polythene bags generated on campus had a positive significant statistical correlation with the distribution of commercial and academic structures on campus. Waste management options to optimize reuse, recycling and reduce waste generation were discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  15. The effects of Hurricane Hugo on suspended-sediment loads, Lago Loiza Basin, Puerto Rico

    Gellis, A.

    1993-01-01

    In the two main tributaries that enter Lago Loiza, Rio Grande de Loiza and Rio Gurabo, 99 600 tonnes of suspended sediment was transported by 58.2??106 m3 of runoff in a 48 h period. The storm-average suspended-sediment concentration in the Rio Grande de Loiza for Hurricane Hugo was 2290 mgl-1, the second lowest for the 12 storms that have been monitored at this site. In Rio Gurabo the storm-average suspended-sediment concentration was 1420 mg l -1, the sixth lowest recorded out of 15 monitored storms. In Quebrada Salvatierra, a small tributary to Rio Grande de Loiza, suspended-sediment concentrations were as low as 33 mg l-1 during peak runoff of 20m3s-1. Normally the suspended-sediment concentrations at this discharge are 300 mg l-1. Hurricane force winds seem to be the most important factor contributing to the lower than expected suspended-sediment loads. High winds caused vegetation and debris to be dislodged and displaced. Debris accumulated on hillslopes and in small channels, blocked bridges and formed debris dams. These dams caused local backwater effects that reduced stream velocities and decreased suspended-sediment loads. -from Author

  16. Multichannel analysis of the surface waves of earth materials in some parts of Lagos State, Nigeria

    2016-09-01

    Full Text Available We present a method that utilizes multichannel analysis of surface waves (MASW, which was used to measure shear wave velocities, with a view to establishing the probable causes of road failure, subsidence and weakening of structures in some local government areas in Lagos, Nigeria. MASW data were acquired using a 24-channel seismograph. The acquired data were processed and transformed into a two-dimensional (2-D structure reflective of the depth and surface wave velocity distribution within a depth of 0–15 m beneath the surface using SURFSEIS software. The shear wave velocity data were compared with other geophysical/ borehole data that were acquired along the same profile. The comparison and correlation illustrate the accuracy and consistency of MASW-derived shear wave velocity profiles. Rigidity modulus and N-value were also generated. The study showed that the low velocity/ very low velocity data are reflective of organic clay/ peat materials and thus likely responsible for the failure, subsidence and weakening of structures within the study areas.

    The study was conducted in response to the lack of epidemiological data in recent time on the use of psychoactive substances by adolescents in metropolitan Lagos-a city unique for its socio-economic profile. We considered some methodological issues omitted in several previous studies. A total of 4,286 school pupils (mean age 15.2) were anonymously administered a Self-Report Questionnaire to ascertain a range of key drug use factors in lifetime and 1-year periods. The rate of use of most of the 14 substances investigated was much higher than reported in any other study on comparable population sample. We found that 61.8 and 32.1% of respondents have used one or more substances in their lifetime and in the past 1 year, respectively. High lifetime rates of use were found for common stimulants: coffee, kolanut, and prescription drugs (barbiturates and minor tranquilisers). The rate of use of proscribed addictive substances, cannabis, heroin, and cocaine, ranged between 4.0 and 4.8%. Missing data and non-response rates were few; however, social acquiescence, under and over reporting, could be mitigant to estimation of rates and patterns of use. We advocate properly articulated school-based educative programmes that can facilitate drug demand reduction.

    Background. ABO hemolytic disease of the newborn is the most common hemolytic consequence of maternofetal blood group incompatibility restricted mostly to non-group-O babies of group O mothers with immune anti-A or anti-B antibodies. Aim. We estimated the risk of ABO HDN with view to determining need for routine screening for ABO incompatibility between mother and fetus. Materials and Methods. Prevalence of ABO blood group phenotypes in blood donors at the donor clinic of the Lagos University Teaching Hospital and arithmetic methods were used to determine population prevalence of ABO genes. We then estimated proportion of pregnancies of group O mothers carrying a non-group-O baby and the risk that maternofetal ABO incompatibility will cause clinical ABO HDN. Results. Blood from 9138 donors was ABO typed. 54.3%, 23%, 19.4%, and 3.3% were blood groups O, A, B, and AB, respectively. Calculated gene frequencies were 0.1416, 0.1209, and 0.7375 for A, B, and O genes, respectively. It was estimated that 14.3% of deliveries will result in a blood group O woman giving birth to a child who is non-group-O. Approximately 4.3% of deliveries are likely to suffer ABO HDN with 2.7% prone to suffer from moderately severe to severe hemolysis. PMID:26491605

    Correlations for the city of Lagos (latitude 6.58 deg. N, longitude 3.33 deg. E) have been found between the records of bright sunshine hours and the daily and monthly components of the total hemispherical solar radiation. Four new models have been developed which include H/H 0 as a predictor in the Angstrom type models for the diffuse and beam fractions. They contain the quadratic term of the sunshine index, (n/N) and are given as follows: Q/H 0 =a+b(H/H 0 )+c(n/N)+d(n/N) 2 Q/H 0 =a+b(H/H 0 )+d(n/N) 2 ; Q/H 0 =a+b(H/H 0 )+c(n/N)+d(n/N) 2 ; Q/H 0 =a+b(H/H 0 )+d(n/N) 2 ; where Q is the diffuse or beam radiation on a horizontal plane. The statistical test carried out showed that the new equations generally improved the prediction of the beam or diffuse components from the Angstrom type equations by over 25%.

    Full Text Available Ebolaviruses (EBOV (family Filoviridae cause viral hemorrhagic fevers in humans and non-human primates when they spill over from their wildlife reservoir hosts with case fatality rates of up to 90%. Fruit bats may act as reservoirs of the Filoviridae. The migratory fruit bat, Eidolon helvum, is common across sub-Saharan Africa and lives in large colonies, often situated in cities. We screened sera from 262 E. helvum using indirect fluorescent tests for antibodies against EBOV subtype Zaire. We detected a seropositive bat from Accra, Ghana, and confirmed this using western blot analysis. The bat was also seropositive for Lagos bat virus, a Lyssavirus, by virus neutralization test. The bat was fitted with a radio transmitter and was last detected in Accra 13 months after release post-sampling, demonstrating long-term survival. Antibodies to filoviruses have not been previously demonstrated in E. helvum. Radio-telemetry data demonstrates long-term survival of an individual bat following exposure to viruses of families that can be highly pathogenic to other mammal species. Because E. helvum typically lives in large urban colonies and is a source of bushmeat in some regions, further studies should determine if this species forms a reservoir for EBOV from which spillover infections into the human population may occur.

    Full Text Available In this study, a total of 90 seafood samples; croaker fish (Pseudotolithus senegalensis, shrimps (Penaeus notialis and blue crab (Callinectes sapidus collected from landing sites along the Lagos Lagoon in Nigeria were examined for the prevalence of Vibrio parahaemolyticus using both biochemical and molecular methods. Biochemical identification of the isolates was confirmed by Polymerase Chain Reaction (PCR. The presence of the virulence-associated tdh (thermostable direct haemolysin, trh1 (thermostable-related haemolysin and trh2 genes in the V. parahaemolyticus isolates was also detected by the PCR method. PCR products from the V.16S primers were sequenced. Antibiotics susceptibility of the isolates was also determined. About, eight isolates were presumptively identified as V. parahaemolyticus, PCR identified five and none of the isolates were positive for the genes tdh or trh. The five isolates sequenced were identified as different strains of V. parahaemolyticus. V. parahaemolyticus_RIMD_2210633 = 2MKSHa remained resistant to all antimicrobials tested. However, only V. parahaemolyticus_MP-2_AY911391 = TBSHy showed strong sensitivity to all the antimicrobials with ampicillin (minimum inhibitory concentration-4 μg/ml. In addition, the other three isolates showed sensitivity for Tetracycline, Ciprofloxacin, Gentamicin and Ceftazidime. Ampicillin resistance in most of the isolates suggests low efficiency of ampicillin in management of V. parahaemolyticus infection.

    Full Text Available Three wood decomposing bacteria isolated from the Lagos lagoon, Bacillus megaterium, Bacillus bataviensis and Paenibacillus sp. were screened for their pectinase producing abilities using pectin as substrate under submerged fermentation (SMF conditions. The results showed that all three isolates produced appreciable pectinolytic activities. Paenibacillus sp. showed the highest pectinase activity when compared with the other two isolates. The optimum pH for pectinase activity for both B. megaterium and B. bataviensis was 8.0 while it was 6.5 for Paenibacillus sp., B. bataviensis, and B. megaterium showed optimum pectinase activity at 60°C and Paenibacillus sp. at 40°C. Metal ions such as Na+ and K+ improved the activity of pectinase produced by the three isolates when compared to the effect of Zn2+ and Mn2+. The molecular weights of the enzymes were also estimated by gel filtration as 29,512 da, 32,359 da, and 25,119 da for Paenibacillus sp., B. megaterium and B. bataviensis respectively. The study has provided a platform for further investigation into the biochemical characterization of the enzyme, and optimization of culture conditions to scale up pectinase production for commercial exploitation.

    Full Text Available The current upsurge of unemployment in Nigeria can be downplayed by entrepreneurship, an economic driver which reflects negatively on the adopted mono-economy of Nigeria with her dependence on oil rather than attaining a multi-diversification in all sectors. The informal entrepreneurship has proved its stance positively in curbing the unemployment issues in all sector and yet there seems to be an aggressive action taken towards its sustainability by the government and in this study, Nigeria. The study focuses on the need to understand the level of social drive in relationship to the performance attained by the informal entrepreneurs. In this regards, the propelling force to why the informal entrepreneur with governmental regulation have a positive performance and this was conducted in Computer village, Ikeja, Lagos. The explorative and causal research was adopted for the study. Survey research was considered appropriate for the study. 250 copies of questionnaire were distributed and 205 were returned depicting 82%. Analysis was done using the SPSS package and the hypothesis tested suggested that there is a significant relationship between social motivators and business competitiveness in the informal electronic market at 5 percent significant level, thereby accepting the alternate hypothesis. This study recommends that the place of family support has been noted to highly affect the motivation of the business and to this end, the basic support gotten from the government should be redesigned (i.e. schools, health, such that the remaining income will be used for expansion or transition while performance is primed.

    Full Text Available Data collected in over 50 years' activity at the C.N.R. meteorological station of Pallanza were analysed to see whether any changes have taken place in some climatic elements and to quantify the extent of such changes. A statistical analysis of the respective historical series was performed on nine meteorological parameters (solar radiation, insolation, air temperature, atmospheric pressure, humidity, cloud cover, precipitation, evaporation and wind, and on two other strictly limnological features: the level of Lago Maggiore and its water temperature at six different depths. In particular, we evaluated the means and the extremes (maxima and minima on an annual, seasonal, monthly and daily level, with the results presented uniformly for all the parameters, also in graphic form. We especially highlighted the trend lines, even though they were not always statistically significant owing to the extreme variability of the meteorological data; in the absence of statistical validity, their significance is an approximate indication of their increasing or decreasing trend. Results showed that insolation, air temperature and atmospheric pressure had increased markedly over time, at least on an annual level, with the trends for solar radiation, humidity and cloud cover also showing an increase, though very slight. Evaporation and wind showed a steady, marked decrease, while precipitation and lake level were essentially stable. Water temperature showed a more varied picture, with the temperature of the topmost levels (to a depth of 10 m continuing to increase.

    Full Text Available Background. Sickle cell disorders are known to have a negative effect on linear growth. This could potentially affect proportional growth and, hence, Cormic Index. Objective. To determine the Cormic Index in the sickle cell anaemia population in Lagos. Methodology. A consecutive sample of 100 children with haemoglobin genotype SS, aged eight months to 15 years, and 100 age and sex matched controls (haemoglobin genotype AA was studied. Sitting height (upper segment and full length or height were measured. Sitting height was then expressed as a percentage of full length/height (Cormic Index. Results. The mean Cormic Index decreased with age among primary subjects (SS and AA controls. The overall mean Cormic Index among primary subjects was comparable to that of controls (55.0±4.6% versus 54.5±5.2%; 54.8±4.5% versus 53.6±4.9% in boys and girls, respectively. In comparison with AA controls, female children with sickle cell anaemia who were older than 10 years had a significantly lower mean Cormic Index. Conclusion. There was a significant negative relationship between Cormic Index and height in subjects and controls irrespective of gender. Similarly, a significant negative correlation existed between age, sitting height, subischial leg length, weight, and Cormic Index in both subjects and controls.

    Samples of poultry droppings were collected from fifty poultry farms in Lagos area of Nigeria. Campylobacter species were isolated from serially diluted samples using Bolton selective enrichment medium under microaerophilic condition at 42 degrees C. Samples of water, both treated and untreated used in the farms were also analysed in the same manner. Fifteen Campylobacter strains were isolated from the droppings. All the strains were identified using biochemical characteristics differentiating Campylobacter species. They were identified as hippurate positive (C. jejuni) and negative species (C. coli). They were biotype' using the extended scheme described by Lior (1984). Campylobacter coli biotype 'I was the most prevalent (66.66%) followed by C. jejuni biotype 1 (20.00%). The biotype ii of the two species accounted for 6.67% each. The C. jejuni biotype III and IV were not isolated during the study. The preponderance of C. coli indicates that poultry can be a major reservoir for the spread of human campylobacteriosis. Poultry farmers, therefore, must ensure prompt and adequate means of disposal of waste materials as well as maintaining good sanitary conditions.

    A descriptive cross-sectional study was carried out to determine the prevalence of cardiovascular risk factors amongst traders in an urban market in Lagos State. Tejuosho market, one of the large popular markets was selected from a list of markets that met the inclusion criteria of being major markets dealing in general goods using a simple random sampling technique by balloting. Four hundred (400) traders were selected using a systematic random sampling. Each trader was interviewed with a well-structured questionnaire and had blood pressure and anthropometric measurements (height, weight and body mass index). Female traders made up (74.3%) 297 of the total population. The mean age was 45.48+11.88 and 42.29+10.96 years for males and females respectively. Majority 239 (59.8%) fell within the age range of 35 - 55 years. The cardiovascular risk factors identified and their prevalence rates were hypertension (34.8%), physical inactivity (92%), previously diagnosed diabetes mellitus (0.8%), risky alcohol consumption (1%), cigarette smoking (0.3%) in females and (17.5%) in males, obesity (12.3%) and overweight (39.9%). The study recommended that any health promoting, preventive or intervention programme for this population would have to be worked into their market activities if it is to make an impact.

    Full Text Available A partir de la década de los 1990, la descentralización política-administrativa de Chile se ha profundizado en forma gradual. Ello se ha expresado, entre otros aspectos, en la creación de gobiernos regionales y en la disposición política del gobierno central de dejar en manos de estas instancias el manejo de recursos para la inversión regional. No obstante, la reconfiguración de la actual división de las regiones no se ha tomado como un tema prioritario dentro de la política descentralizadora en cuestión. Sin embargo, ello no ha implicado que se esté obviando el tema por completo; ya que a nivel extraoficial, y de parte tanto del gobierno central como regional, se plantea la necesidad de hacer una propuesta de reestructuración de la división política-administrativa del país. Este estudio de caso fija su atención en las demandas de reestructuración recién mencionadas, haciendo especial hincapié en la observación del fenómeno de demanda por la regionalización de la provincia de Valdivia, en la décima región de Los Lagos, Chile, durante los años 1995/96. Dicho trabajo se realizó bajo la óptica de la negociación centro-región, con los objetivos de describir los componentes del proceso y de reconocer las condicionantes de las acciones de los actores en el mismo. Los resultados del estudio están vinculados al rol que ejercen los actores en el conflicto y negociación centro-región. Se consiguió realizar una caracterización de ellos, además de constatar la relación de clientela política que se produce entre la elite nacional y regional, como factor determinante en el resultado de la negociación. De la misma manera, se comprobó que el diseño institucional del sistema político induce este tipo de vínculo entre las elites mencionadas. Finalmente, el estudio presenta una serie de recomendaciones para el fortalecimiento de la política pública de descentralización de Chile, que están en marco de aminorar los

    Full Text Available Argentina, históricamente, ha presentado profundas desigualdades socioeconómicas regionales. Las provincias del Noroeste mostraron notorias diferencias respecto a las pampeanas en la producción de riqueza. Así, a fines del siglo xx, mientras en las provincias pampeanas la pobreza alcanzaba al 32,9% de su población, en el norte estas privaciones se duplicaban. Este artículo tiene por objeto analizar comparativamente las características de estas privaciones —considerando escalas provinciales y departamentales—, vinculándolas a su vez con las transformaciones económicas y productivas y con los problemas de empleo a lo largo del siglo xx e inicios del xxi. Los resultados advierten un notorio proceso de fragmentación socioterritorial como corolario de la persistencia de la desigualdad. Se destaca el recrudecimiento de dicha fragmentación en determinadas provincias y departamentos argentinos.

    Nigeria with a growth rate of 28%, accounts for over two thirds of the West African population. It also has one of the highest maternal mortality rates in the world with contraceptive prevalence among married couples less than 10%. Despite its safety and efficacy vasectomy appears to be unpopular in our environment. To assess the perception and acceptance of married men and women towards vasectomy and the influence of the spouse on the man's decision to accept or reject vasectomy. A cross sectional questionnaire based study. With an estimated population of 20 million, Lagos is the most cosmopolitan and urbanised city in Nigeria and accounts for 65% of all commercial activities in the country. Virtually all the tribes in Nigeria are represented in the city. Literate pregnant women recruited from the antenatal clinics and literate new fathers. All subjects were recruited from three health facilities in the Lagos metropolis. Twenty seven point five and twenty one percent of the men and women respectively had a good Knowledge of vasectomy while 49.1% and 19% of all men and women respectively with good knowledge would accept vasectomy (or agree for their spouses to have the procedure). Overall acceptance rates for men and women were 26 and 13.5% respectively while 92% of men who can opt for vasectomy will only do so if their spouses agree. Knowledge about vasectomy was the strongest single factor influencing the acceptance of vasectomy (p= 0.013) with stronger correlation among men than women (p=0.005 vrs p=.0.023). Knowledge and acceptance of vasectomy is significantly better in males than female Nigerians living in Lagos.

La “Global Biodiversity Information Facility” GBIF permite el acceso a más de 321 millones de registros, alojados en 379 instituciones. Los murciélagos neotropicales son un grupo muy diverso y especializado y la información geográfica del grupo se ha incrementado desde hace unos años, pero son pocos los reportes acerca del tema. El objetivo de este estudio fue analizar el número de registros disponibles en GBIF de los murciélagos neotropicales de 21 países de América. Por lo tanto, se evaluó la consistencia del nombre científico y la calidad geográfica a escala de país. Además, se evaluaron vacíos de información sobre una grilla de 1° latitud y 1° longitud. Hubo cerca de 1/2 millón de registros, de los cuales el 58% no incluyeron coordenadas geográficas; el 52% pasaron las dos evaluaciones. Se estimó que el 54% del área geográfica analizada no tiene registros; los vacíos están en centros de biodiversidad como la Amazonía y la Patagonia. En conclusión nuestros resultados sugieren que los datos disponibles en GBIF tienen sesgos geográficos y en los nombres científicos. Los datos de GBIF representan parcialmente las riquezas de murciélagos, además los principales vacíos de información se encuentran en América del Sur.

    Full Text Available This study sets out to find out whether parental socioeconomic status, family structure and living environment are predictors of violence against children. Three hypotheses were formulated to guide the investigation. Descriptive survey research design was adopted for the study and the population of the study consisted of all the children in public primary schools and in junior secondary schools within Lagos state of Nigeria. A multistage sampling technique was adopted for the study. Random samples of twenty five children were picked from each of the sixteen schools selected. This gives a total 400 participants that were used for the study. Experts in Sociology, measurement and evaluation certified the content validity of the questionnaire, while the co-efficient of the reliability of the four sections of the questionnaire were ascertained to be 0.63; 0.68; 0.66 and 0.73, respectively for sections A,B,C and D. Chi-square statistical tools was used to test the hypotheses formulated. Major findings of the study include the fact that parental socioeconomic status significantly influence violence against children, family structure significantly influence violence against children and that living environment also significantly influence violence against children. This study conclude by recommending among others that the Lagos State government should put machinery in motion to improve the poverty level of individuals living in Lagos State of Nigeria and should also make available social services and amenities that are supportive of family well being in order to avoid any form of violence against children.

    2010-01-01

    In recent times, Lagos Island has been hit by a cyclical crescendo of juvenile crime perpetrated by "Area Boys," jobless youths who deal in robbery, extortion, and blackmail. Such deviant behavior has historical roots back to colonial times, when youths labeled "alkali boys," "boma boys," and "cowboys" roamed the heart of the capital of Britain's colony of Nigeria between the 1920s and 1960s. Examining the various types of juvenile delinquents on Lagos Island, this article explores the urban experience of criminally minded youths through exploration of street-life, vagrancy, criminality, and public reactions.

    The study of low energy cosmic particles allows to analyze several aspects of major interest for space weather. Ground detectors permit to observe secundary particles produced during the cascades developed in the atmosphere. The characterization of a prototype for a water Cherenkov radiation particles detector, in the frame of the LAGO collaboration (Latin American Giant Observatory), is presented in this work. The collaboration plans to install this detector at the LAGO antarctic site. The developed acquisition system and the method used to make the energy callibration of the detector are detailed here, as also corrections for atmospheric effects.

De los 530 162 habitantes de la provincia 43 358 (6.5% son pueblos originarios de las etnias Wichí, Qom, y Pilagá. Los problemas particulares de estas comunidades se deben a las distancias entre las comunidades y los servicios médicos regulares, y a las diferencias culturales. La situación mejoró en los últimos 30 años al facilitar y acercar los servicios médicos a las poblaciones, incorporar y mejorar la preparación de las parteras aborígenes, formar agentes sanitarios, auxiliares médicos y la mejora de las condiciones sociales en general. Los resultados más destacados fueron la disminución de los índices de mortalidad infantil, de la incidencia de tuberculosis, ninguna muerte por meningitis tuberculosa desde 1999. Es de importancia haber incorporado a la enseñanza los idiomas propios de las etnias y el manifiesto respeto a sus diferentes costumbres. Los cambios originaron nuevos riesgos: accidentes viales, alcoholismo en los jóvenes, obesidad, diabetes (antes no diagnosticada, y crisis de liderazgo en las comunidades.

Unfortunately, the country does not have the resources to assess this critical indicator with the conventional health information system and measuring its progress toward the goal of ending preventable maternal deaths is almost impossible. Médecins Sans Frontières (MSF conducted a cross-sectional study to assess maternal and perinatal mortality in Makoko Riverine and Badia East, two of the most vulnerable slums of Lagos.The study was a cross-sectional, community-based household survey. Nearly 4,000 households were surveyed. The sisterhood method was utilized to estimate maternal mortality and the preceding births technique was used to estimate newborn and child mortality. Questions regarding health seeking behavior were posed to female interviewees and self-reported data were collected.Data was collected from 3963 respondents for a total of 7018 sisters ever married. The maternal mortality ratio was calculated at 1,050/100,000 live births (95% CI: 894-1215, and the lifetime risk of maternal death at 1:18. The neonatal mortality rate was extracted from 1967 pregnancies reported and was estimated at 28.4/1,000; infant mortality at 43.8/1,000 and under-five mortality at 103/1,000. Living in Badia, giving birth at home and belonging to the Egun ethnic group were associated with higher perinatal mortality. Half of the last pregnancies were reportedly delivered in private health facilities. Proximity to home was the main influencing factor (32.4% associated with delivery at the health facility.The maternal mortality ratio found in these urban slum populations within Lagos is extremely high, compared to the figure estimated for Lagos State of 545 per 100,000 live births.

El universo estuvo constituido por los 103 casos notificados con lepra en la provincia de Las Tunas, en el período de enero de 2003 a diciembre de 2012. La información se obtuvo por las encuestas epidemiológicas existentes en el Departamento de Estadística de la Dirección Provincial de Salud y en el Centro Provincial de Higiene, Epidemiología y Microbiología. Se creó una base de datos en Epinfo versión 3.3.3, donde se tabularon los datos de las encuestas. El análisis de los resultados se expresó en números absolutos, tasas y porcentajes para su mejor interpretación, obteniéndose como resultado que la tasa de detección de casos tiene un comportamiento irregular, el año de mayor incidencia fue el 2009, con 20 casos. Se notificaron tres casos de lepra infantil; las formas paucibacilares representaron el 51,5%; el modo de detección más frecuente fue el espontáneo. Existe transmisión activa y todo ello puede ser reflejo de la ausencia de un trabajo consolidado en el programa de control de la enfermedad

La muestra fue de 5497 niños y niñas entre 5 y 15 años de edad, de siete departamentos provinciales. Las mediciones fueron realizadas entre 1980 y 2000, lo que facilitó, además, un análisis secular de la variabilidad de los parámetros estudiados. Los resultados obtenidos se han contrastado con los correspondientes a otros grupos humanos previamente estudiados con idéntica metodología. Por lo que respecta en concreto al sobrepeso y obesidad calculado a partir de los criterios de Cole et al (2000 cabe mencionar que la prevalencia de ambas condiciones malnutritivas es considerablemente inferior a la registrada hasta el momento para la mayoría de los países latinoamericanos utilizando protocolos basados en el IMC. Concretamente la proporción actual es en Catamarca de un 7% de sobrepeso y un 2% de obesidad, habiéndose observado que la tendencia secular al aumento de ambas condiciones, ha sido muy leve en los últimos veinte años.

    Full Text Available Entre 1992 y el 2001 el hospital de Las Lomitas notificó 85 casos de leishmaniosis tegumentaria, 72.9% en hombres, 91.8% en mayores de 10 años, y el 10.5% con manifestación mucosa. La presentación clínica más frecuente fue la úlcera simple en miembros inferiores. Las características epidemiológicas y clínicas fueron compatibles con la infección debida a Leishmania (Viannia braziliensis. La distribución anual de aparición de lesiones fue bimodal, la abundancia mostró asociación con el caudal del río Bermejo y la precipitación pluvial del año anterior. La intradermorreacción y la anamnesis sugieren como principal actividad de riesgo la pesca en el río. Se colectaron 1018 Phlebotominae, Lutzomyia neivai (97.1%, L. migonei (2.3% y L. cortelezzii (0.6%, la proporción peridomicilio/bosque en galería del río Bermejo fue 1/9, en composición semejante a las poblaciones del mismo río en la provincia de Salta. El incremento de casos observado desde 1992, la ejecución de obras de desarrollo que implican cambios ambientales, y la potencialidad de instalación de un ciclo periurbano vuelven necesario implementar un programa de vigilancia activa entomológica y de casos en el área chaqueña.

Métodos: se realizó un estudio retrospectivo, observacional, descriptivo en el período comprendido de enero de 2005 a septiembre de 2010, en los servicios de neonatología de la provincia La Habana. Se estudió el total de recién nacidos vivos (207 con menos de 35 semanas de edad gestacional y un peso inferior a 1 750 g al nacer ingresados en las unidades de cuidados intensivos neonatales de este territorio. Resultados: el 42,8 % correspondió con los nacidos entre las semanas 33 y 34,6, y un 42,8 % con un peso entre 1 250 y 1 499 g. El 89,8 % de los recién nacidos presentaron una retina inmadura y un 10,1 % desarrolló retinopatía de la prematuridad. El 88,8 % de los tratados con láser evolucionaron favorablemente. Conclusiones: la retinopatía de la prematuridad ha disminuido en los últimos años a pesar de que existe un incremento en el bajo peso al nacer y prematurez. La edad gestacional menor de 34,6 semanas, el peso al nacer menor de 1 500 g y el síndrome de dificultad respiratoria fueron los factores más importante en la aparición de la retinopatía. Con el diagnóstico precoz de la enfermedad se trató oportunamente, logrando disminuir las secuelas y mejoría de la calidad de vida.

    Full Text Available Abstract Background Infertility is a major problem in sickle cell disease patients, especially in males. In addition to low serum testosterone, other abnormalities involving the accessory sex organs, such as the seminal vesicles and the prostate gland, as well as marked decrease in ejaculate volume may be observed in male HbSS patients. Hence, the need to study the role of sex hormones as a cause of infertility in male HbSS patients. Methods An unmatched case-control study was performed using seventy-five consenting subjects from Lagos University Teaching Hospital. These included 47 patients with haemoglobin phenotype SS from the Sickle cell clinic and 28 volunteered medical students and members of staff with haemoglobin phenotype AA. Demographic data were obtained using a self-administered questionnaire. A total of 5 mls of blood was collected from each subject between 9.00 am & 11.am, and assayed for serum testosterone concentration. Results The concentrations of serum testosterone in HbSS patients ranged from 0.2 to 4.3 ng/ml with a mean of 1.28 ± 0.72 ng/ml whilst the values in HbAA controls ranged from 1.2 to 6.9 ng/ml with a mean of 2.63 ± 1.04 ng/ml. Seven (25.0% of the 28 controls had serum testosterone concentration lower than the quoted reference (normal range whereas 44 (93.6% of the 47 HbSS subjects had serum testosterone concentration lower than the reference range. Conclusion Overall, subjects with HbSS have significantly lower mean serum testosterone than HbAA controls.

    2016-12-01

    Full Text Available Background. Paediatric endoscopy is now standard care in the developed world for the management of gastrointestinal (GI disorders. However, in developing countries endoscopy remains an underutilised tool. Objective. To determine the indications and the spectrum of endoscopic findings in children seen at the Lagos University Teaching Hospital, Nigeria. Methods. The indications for upper GI endoscopy and endoscopic findings in children ≤16 years old, referred for the procedure from June 2013 to June 2016, were documented. The endoscopic yield in these children was also determined. Results. In total 71 children were referred for upper GI endoscopy during the study period. There were 35 boys and 36 girls aged 3 months to 16 years. The indications for upper endoscopy were recurrent abdominal pain in 37 (52.1%, upper GI bleeding in 17 (23.9%, recurrent vomiting in 7 (9.9%, dyspepsia in 5 (7.0, heartburn in 2 (2.8%, dysphagia in 1 (1.4, portal hypertension in 1 (1.4 and ingestion of corrosives in 1 (1.4% of the subjects. Endoscopic findings were as follows: gastritis 19 (26.8%, hiatus hernia in 13 (18.3%, gastric erosions in 12 (16.9%, oesophageal varices 6 (8.4%, duodenitis in 4 (5.6%, gastric ulcer in 3 (4.2%, gastric polyp in 2 (2.8%. The overall endoscopic yield was 60.2%. Conclusion. There is a need to increase the awareness of the role of paediatric endoscopy in the diagnosis and treatment of GI disorders in developing countries. Recurrent abdominal pain still remains a relevant indication for the procedure. The need to develop training programmes for paediatric endoscopy and paediatric gastroenterology in general in developing countries cannot be overemphasised.

  13. Bearded saki feeding strategies on an island in Lago Guri, Venezuela.

    Science.gov (United States)

    Norconk, Marilyn A; Conklin-Brittain, Nancy L

    2016-05-01

    Free-ranging bearded sakis (Chiropotes spp.) live in relatively large social groups (22-65+), inhabit very large home ranges (200-1,000 ha), and travel long distances (1.8 to >7 km) each day. While these characteristics would seem to reduce their ability to occupy habitat fragments, several studies suggest otherwise. The key to their success may lie in their dietary adaptations. Bearded sakis are strongly frugivorous, but are primarily seed eaters, and are able to ingest both young and mature fruit. We examined feeding activities of a group of bearded sakis over a 19-month period on a 180 ha island in Lago Guri, Venezuela. Given their feeding adaptations, we predicted that they would minimize peaks and troughs in plant species used for food, limit seasonal variation in the mechanical properties of foods ingested, and balance ingestion of energy-rich foods (e.g. lipids, nonstructural carbohydrates (TNC), and/or free simple sugars). We found that bearded sakis on Danto Manchado had a diverse (plant-based) diet, but two resources (Pradosia caracasana, Sapotaceae, and Oryctanthus alveolatus, Loranthaceae) provided a stable dietary base and were present in the diet almost every month. Second, we found little variation in the mechanical-resistance properties of fruits opened seasonally. Third, they alternated months ingesting foods with high TNC content and months of high lipid content. This may be an attempt to balance energy intake from available foods. Finally, their social propensity to split up into subgroups may predispose them to reduce group sizes to accommodate smaller available areas. We suggest that bearded sakis use both ecological and behavioral mechanisms to survive in smaller-than-typical areas. Longer-term studies (beyond a few generations) of bearded sakis in habitat fragments would allow us to estimate minimum survival area and identify critical resources or resource combinations. © 2015 Wiley Periodicals, Inc.

  14. Assessment of Viability Appraisal Practice by Estate Surveyors and Valuers in Lagos Metropolis, Nigeria

    2017-01-01

    Full Text Available A capital investment appraisal is a means of ensuring value for money. It is not meant to provide an indication of profit or loss, but rather a comparison of costs in relation to those areas where there is an opportunity or an inclination for change. The decision to invest in a project is based on the expectation of future returns since a rational investor does not expect to incur loss on his capital outlay. This decision making is usually hinged on advice obtained during pre-investment appraisal. This study is aimed at evaluating the mode of practicing investment viability appraisal by Estate Surveyors and Valuers in Lagos metropolis. The data for the study was obtained by randomly administering structured questionnaires on eighty-seven (87 practicing Estate Surveyors and Valuers in the study area and the findings were analyzed through descriptive statistical tools such as the Likert scale to present the result. Findings revealed that the payback period is the most adopted appraisal technique in practice as evidenced with a mean score of 3.57. The objective (s of the investor is also the most significant factor being considered while selecting appraisal technique with a mean score of 3.83 while the problems of actual return varying from the expected return and also difficulty in the repayment of loans always result when a wrong viability technique is employed. The success of any viability study goes beyond knowing the objective (s of the investor; therefore, it was recommended that appraisers should ensure that they are equipped with adequate knowledge required for the execution of feasibility and on viability studies because knowing the right viability criteria for a particular objective will help in advising an investor on a course of action that will best achieve the developer’s objective.

    Full Text Available Los estudios ecológicos sobre la familia Corixidae (Hemiptera en México son escasos y fragmentados, por lo que se analiza su variación espacial y temporal en un lago urbano con algunas variables ambientales. Los muestreos se realizaron mensualmente, de julio de 2000 a junio de 2001, ubicando tres estaciones litorales de muestreo; en cada una se determinó: profundidad, transparencia, temperatura, oxígeno, pH, conductividad, dureza y alcalinidad. Los coríxidos se capturaron con red de cuchara de forma rectangular. Se efectuó un análisis de correlación simple entre la abundancia total de los coríxidos y las variables físicas y químicas registradas. Se registraron tres especies: Graptocorixa abdominalis (Say, 1832, con 53% de abundancia; Corisella edulis (Champion, 1901 con 43% y Krizousacorixa femorata (Guérin, 1857 con 1%. De un total de 2423 organismos capturados, la mayor abundancia se registró en marzo, junto con los valores más altos de profundidad y oxígeno. La menor abundancia se presentó en junio, con los valores más bajos de alcalinidad. La correlación de variables y abundancia total fue positiva y significativa con profundidad, oxígeno y conductividad. La Estación I presentó la mayor abundancia de coríxidos y la estación III la menor abundancia. Las variaciones registradas en la abundancia se deben al aporte de agua y a la ubicación de las estaciones de muestreo.

    Lago de Colina (Colina Lake) is located about 180 km south of the city of Chihuahua (Mexico), and during the Semana Santa (Holy Week) vacation period its recreational use is high. The objective of this study was to quantify coliform and heavy metal levels in this water body before and after the Holy Week vacation period in 2010. Twenty sampling points were randomly selected and two water samples were collected at each point near the surface (0.30 m) and at 1 m depth. After the Holy Week vacation the same twenty points were sampled at the same depths. Therefore, a total 80 water samples were analyzed for fecal and total coliforms and levels of the following metals: Al, As, B, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Se, Si and Zn. It was hypothesized that domestic tourism contaminated this water body, and as a consequence, could have a negative impact on visitor health. An analysis of variance (ANOVA) study was performed for each element and its interactions considering a factorial design where factor A was sample date and factor B was sample depth. Fecal coliforms were only detected at eight sampling points in the first week, but after Holy Week, both fecal and total coliforms were detected at most sampling points. The concentrations of Al, B, Na, Ni and Se were only statistically different for factor A. The levels of Cr, Cu, K and Mg was different for both date and depth, but the dual factor interaction was not significant. The amount of Ca and Zn was statistically different due to date, depth and their interaction. No significant differences were found for any factor or the interaction for the elements As, Fe and Mn. Because of the consistent results, it is concluded that local tourism is contaminating the recreational area of Colina Lake, Chihuahua, Mexico. PMID:21776236

    Full Text Available Durante las últimas décadas, las ciudades posindustriales latinoamericanas se han constituido como nodos de la red mundial. La apertura de sus economías nacionales, posibilitó que algunas de estas ciudades se conviertan en los lugares preferidos para la localización de funciones y actividades de enlace con las redes globales de carácter comercial, productivo, financiero y cultural. Estos espacios urbanos avanzan progresivamente hacia polos segmentados de desarrollo que se manifiestan en la sociedad a través del acceso diferencial a bienes y servicios, surgiendo una dualidad espacial, aparentemente planteada, entre el espacio público y privado, y promoviendo fenómenos de exclusión o inclusión en una tensión permanente. Así se configuran en archipiélagos promotores de cambio y sujetos a diversas dimensiones de análisis. Para interpretar este fenómeno en relación a la inversión de capital, se ha seleccionado como territorio de análsis, un área del sector noroeste de la ciudad de Córdoba, Argentina. Se trata de un complejo comercial de gran magnitud y significación simbólica para la ciudad: Grupo Dinosaurio. El presente trabajo ensaya una aproximación exploratoria para identificar las tensiones producto de los conflictos por el avance en el espacio urbano de inversiones en espacios segmentados, promotores de cambio y su relación con el espacio público- privado, y la consecuente segregación socio- espacial.

    Full Text Available Background: Family planning programs, researches, and studies have focused mainly on women with little attention to men′s role in the contraceptive choices by the couple. Men′s exclusion from these programs has serious implications on the acceptance and use of contraceptives by the couple. Objective: To determine the influence of male partners on contraceptive use of their spouses. Subjects and Methods: This was a cross-sectional descriptive study at a Tertiary Care Centre in Lagos, Nigeria. It was conducted from January 1 to April 30, 2010, where all consecutive consenting pregnant women were given structured questionnaires to give to their partners so as to evaluate the contribution of the male partners to contraceptives use in their spouses as well as assess their awareness and knowledge of contraception. Categorical variables were analyzed using Chi-square test or Fisher′s exact test as appropriate while continuous variables by t-test. P < 0.05 was considered significant. Results: Of the 370 respondents, only 51.9% (192 knew about female contraceptive methods, while 50% (185 were willing to allow their wives to use contraception. Barrier method (17.3% and periodic abstinence (15.7% were the leading preferred choice for their wives. However, bilateral tubal ligation was the least preferred method (1.6%. Previous counseling of male partner significantly influenced their decision to allow their wives to use contraceptives (P = 0.001. Conclusion: Involving the male partner in family planning counseling plays an important role in increasing the acceptance and use of contraceptives by the couple.

    Full Text Available Background. Neonatal jaundice remains a leading cause of preventable brain damage, mental handicap, physical disabilities and early death among infants. The high mortality and morbidity from neonatal jaundice is exacerbated by the poor understanding and mismanagement of this common neonatal problem by the general populace, leading to dangerous delays and complications. Objective. To assess the knowledge of pregnant women on the causative factors, treatment modalities and sequelae of neonatal jaundice. Methods. Data were obtained from all consecutive women who attended the antenatal clinic of the Lagos University Teaching Hospital, Nigeria, from January 2013 to April 2013, using a pretested questionnaire focusing on knowledge of neonatal jaundice and its causes, treatment and complications. Results. The study participants numbered 395, of whom 213 (53.9% were within the age range of 30 - 39 years. Only 101 (25.6% participants gave a correct definition of neonatal jaundice. The highest proportion of those who did not give a correct definition were from the lower socioeconomic groups V and IV (χ2=12.08, p=0.017. Participants who did not know the causes numbered 313 (79.2%, while 325 (82.2% participants chose ineffective treatment options. Furthermore, 296 (74.9% respondents, especially those with a low level of education, did not identify the complications correctly (χ2=12.61, p=0.006. Conclusion. Women in the study showed inadequate knowledge of and misconceptions regarding neonatal jaundice, which must be addressed in order to reduce significantly the devastating consequences of this common condition.

    Full Text Available CONTEXT AND OBJECTIVES: Adverse drug reactions (ADRs may cause prolonged hospital admissions with high treatment costs. The burden of ADRs in children has never been evaluated in Nigeria. The incidence of pediatric ADRs and the estimated cost of treatment over an 18-month period were determined in this study. DESIGN AND SETTING: Prospective observational study on children admitted to the pediatric wards of the Lagos State University Teaching Hospital (LASUTH in Nigeria, between July 2006 and December 2007. METHODS: Each patient was assessed for ADRs throughout admission. Medical and non-medical costs to the hospital and patient were estimated for each ADR by reviewing the medical and pharmacy bills, medical charts and diagnostic request forms and by interviewing the parents. Cost estimates were performed in 2007 naira (Nigeria currency from the perspectives of the hospital (government, service users (patients and society (bearers of the total costs attributable to treating ADRs. The total estimated cost was expressed in 2007 United States dollars (USD. RESULTS: Two thousand and four children were admitted during the study; 12 (0.6% were admitted because of ADRs and 23 (1.2% developed ADR(s during admission. Forty ADRs were suspected in these 35 patients and involved 53 medicines. Antibiotics (50% were the most suspected medicines. Approximately 1.83 million naira (USD 15,466.60 was expended to manage all the patients admitted due to ADRs. CONCLUSIONS: Treating pediatric ADRs was very expensive. Pediatric drug use policies in Nigeria need to be reviewed so as to discourage self-medication, polypharmacy prescription and sales of prescription medicines without prescription.

    Full Text Available Background: Technological advances and computing have expanded both the scope and capacity of diagnostic medical imaging (the radiography profession. This has created many diverse imaging modalities which in turn, have culminated in different sub-specialties in the profession. Objective: The aims of the study were to determine the level of awareness of imaging sub-specialties, preferred sub specialties and reasons for preferences of sub-specialties in senior level radiography students of the University of Lagos. Methods: The study was a prospective cross-sectional survey. Consents were obtained before the students were recruited for the study. Data Collection and Analysis: A questionnaire semi-structured in line with objectives of the study was used in data collection. A computer software Epi Info version 3.3 was used to analyze data while results were expressed as percentages of responses and were presented in tables and pie charts. Results : Greater than 90% showed awareness of sub-specialties in the radiography profession whereas 35% preferred ultrasonography to other sub-specialties. The least preferred sub-specialty was conventional radiography (4.3%. Remuneration (73.3% and less physical exertion (73.3% were major attractors to preferred sub-specialties whereas concerns over radiation hazard were major detractors (58.3%. Conclusion : Awareness of sub-specialties in the radiography profession was high amongst students studied. Furthermore, ultrasonography was the most preferred sub-specialty among the respondents. Remuneration was the main attractor to sub-specialties whereas fears over effects of ionizing radiation were the major detractors to some sub-specialties.

    This study assessed knowledge, prevalence, associated factors and mechanisms of coping with stress among bankers in Lagos State. It was a descriptive cross sectional study. A two stage sampling technique was used to select two hundred and twenty seven (227) respondents. Data was collected using a structured self administered questionnaire. The analysis was done using Epi-info version 2002 software and Chi Square was used to determine association between variables at p value 0.05. Fischer's Exact test was used where Chi-square was not valid. The age range of respondents was between 20 and 49 years while the mean age was 31.3 +/- 5.0 years. Only 3.6% had good level of knowledge about stress, 42.2% had fair level while more than half of the respondents had poor level of knowledge about stress (54.3%). Majority (67.0%) of the respondents were moderately stressed while one quarter (24.7%) were highly stressed. Majority (92.4%) of the respondents used good coping mechanisms though 69.5% of the respondents also used bad coping mechanisms. A greater proportion of those who had poor knowledge about stress were stressed or highly stressed (p = 0.002). A statistically significant association was also found between the departments in the bank and level of stress of the respondents (p = 0.002). The prevalence of stress was high among the bank workers studied. It is recommended that effective stress management programmes are implemented to address the problem of stress among bank workers.

    Full Text Available Background and Objective: The informal sector population in developing nations has low health coverage from Community Based Health Insurance (CBHI and problems such as limited awareness about the potential impact of prepayment health financing and the limited resources to finance health care can impede success. This study assessed the community based health insurance scheme uptake and determinants in Olowora, Lagos State. Methods: This was a descriptive cross sectional study carried out in July 2010 in all households of 12 out of 41 streets in Olowora,by multistage sampling. Four hundred and sixteen interviewer-administered questionnaires were completed and returned. Analysis was by Epi- info version 3.5.1 software. Results: Although 75.5% of respondents were aware of the Community Health Insurance scheme at Olowora, just about half (49.5% of them had good knowledge of the scheme. A substantial proportion (44.2% of respondents did not believe in contributing money for illness yet to come, and majority (72.3% of such respondents prefers payment for health care when ill. While about half (53% of respondentshad enrolled into the community health insurance scheme, 45.6% of those who had not enrolled were not aware of the scheme. Lack of money was the main reason (51.5% why some enrollees had defaulted. Conclusion: The study identified information gaps and poor understanding of the scheme as well as poverty as factors that have negatively affected uptake. The scheme management has to re-evaluate its sensitization programmes, and also strengthen marketing strategies with special emphasis on the poor.

    Full Text Available Occupational exposure to lead is common among automobile technicians and constitutes 0.9% of total global health burden with a majority of cases in developing countries. The aim of this study was to determine and compare the blood lead levels of automobile technicians in roadside and organised garages in Lagos State, Nigeria. This was a comparative cross-sectional study. Data were collected using interviewer-administered questionnaires. Physical examinations were conducted and blood was analysed for lead using atomic spectrophotometery. Statistical analyses were performed to compare the median blood lead levels of each group using the independent sample (Mann-Whitney U test. Seventy-three (40.3% of the organised compared to 59 (34.3% of the roadside groups had high blood lead levels. The organised group had statistically significant higher median blood lead levels of, 66.0 µg/dL than the roadside 43.5 µg/dL (P < 0.05. There was also statistically significant association between high blood lead levels and abnormal discolouration of the mucosa of the mouth in the organised group. Automobile technicians in organised garages in Lagos have higher prevalence of elevated blood lead levels and higher median levels than the roadside group. Preventive strategies against lead exposures should be instituted by the employers and further actions should be taken to minimize exposures, improve work practices, implement engineering controls (e.g., proper ventilation, and ensure the use of personal protective equipment.

    Lago Verde is a maar lake (18 36 43 N; 95 20 52 W) located on the Gulf Coast of Mexico in "Los Tuxtlas" region. The area was cover by tropical rain forest and is part of the core area of the earliest Mesoamerican cultures. A 6 m sediment core was obtained in order to document vegetation and lake level history of this area. Lago Verde is a shallow, eutrophic lake (max. 4 m), the natural vegetation has been removed and grasslands with some tropical trees such Bursera grows around the lake. According with the radiocarbon chronology the sequence covers the last 2500 yr BP. At the base of the sequence low abundance of tropical trees is record, with intermediate lake levels. A sudden change in the pollen stratigraphy occurs at ca. 2000 yr BP, with important presence of Poaceae, Ambrosia and Cheno.-Am. along with Zea mays indicating human activity in the area. This is associated with a change in limnological conditions, recording turbid, shallow environments. This pollen signals correlates with dry phases in Yucatan, suggesting that this dry climatic signal probably had effect on an ample area of Mexico. However, at 1200 yr BP, no more Zea mays pollen is recovered suggesting the abandonment of the area. Lake levels recover as well as the tropical forest. The last 150 yr BP is characterized by the reduction in the pollen of tropical forest trees, presence of Zea mays, increased erosion rates, turbidity and eutrophication in the lake, all related to deforestation.

    On 17 May 2009, the first two cases of 2009 pandemic influenza A(H1N1) were confirmed in the Metropolitan region (Santiago, Chile). On 6 June 2009, Chile reported 500 confirmed cases, seven severe and two fatal. Because six of the severe cases and the two deaths occurred in the region of Los Lagos in southern Chile, a retrospective study was conducted using data on emergency room visits as well as laboratory viral surveillance, during the period from 1 April to 31 May, in order to establish the date of the beginning of the outbreak. From 1 to 27 June, data were collected in real time, to establish the real magnitude of the outbreak, describe its transmission, clinical severity and secondary attack rates. Confirmed cases, their household contacts and healthcare workers were interviewed. This analysis showed that the outbreak in Los Lagos started on 28 April. By 27 June, a total of 14.559 clinical cases were identified, affecting mostly 5-19 year-olds. The effective reproduction number during the initial phase (20 days) was 1.8 (1.6-2.0). Of the 190 confirmed cases with severe acute respiratory infection, 71 (37.4%) presented a risk condition or underlying illness.

    Late diagnosis and interventions characterize childhood neurodevelopmental disorders in Sub-Saharan Africa. This has negatively impacted on the prognosis of the children with neurodevelopmental disorders. This study examined the prevalence and pattern of neurodevelopmental delays among children under the age of 3 years attending immunization clinics in Lagos State, Nigeria and also affords opportunity of early follow-up and interventions, which had been documented to improve prognosis. The study involved two stage assessments; which consisted of first phase screening of the children for neurodevelopmental delays in immunization clinics at primary healthcare centers Lagos State, Nigeria and second phase which consists of definitive clinical evaluation and follow-up interventions for children screened positive for neurodevelopmental delays. Twenty seven (0.9%) of a total of 3,011 children under the age of 3 years were screened positive for neurodevelopmental delays and subsequently undergoing clinical evaluation and follow-up interventions. Preliminary working diagnoses among these children include cerebral palsy, autism spectrum disorder trait, nutritional deficiency, Down syndrome and Non-specific neurodevelopmental delay with co-morbid seizure disorder accounting for 33.3%, 14.8%, 18.5%, 7.4% and 25.9% respectively. This is a preliminary report that would be followed up with information on medium and long term intervention phase.

    Insecticide-treated nets (ITNs) have proven to be one of the most effective means of reducing malaria morbidity and mortality in children and pregnant women. This study is carried out to determine the practice and determinants of ITN use for children under five years among care givers in an urban area of Lagos State. A community-based, cross sectional study was carried out in Lagos State in April 2007 among three hundred and forty (340) care givers primarily responsible for child care at home. They were selected by a multi-stage sampling method using a pre-tested, interviewer-administered, structured questionnaire. ITN use rate for under-fives was high (61.8%) and this was significantly determined by care giver's marital status (P level of care giver and occupation of head of the household were not significant determinants. There is need for health campaigns on ITNs targeted at unmarried care givers of young children. In addition, we also recommend social marketing of modern family planning methods to reduce family size, thereby increasing chances of ITN use among children less than five years to reduce malaria burden.

    Full Text Available Objective: This hospital-based retrospective cohort study was undertaken with a view to determine the epidemiological trend of measles in Lagos State, Nigeria Methods: Medical records of clinically diagnosed measles patients from nine referral public hospitals in Lagos State between 1998 and 2007 were retrieved, transcribed and reviewed. Data were analyzed using standard methods. Results: A total of 35,500 clinically confirmed cases and 835 deaths (case fatality rate = 2.35%/10 years were recorded. The mean incidence was estimated at 19 cases per 100,000 population/year. A consistent seasonality pattern of measles was observed for the study period. The under-fives accounted for the highest reported cases (76.30% while, the under-1 year recorded highest mortality (53.8%. Notable shift of measles vulnerability from under-1year to under-fives was observed. Although there was significant difference between cases and deaths among the age groups (p0.05. Conclusion: This study recorded high incidence and case fatality of measles, which poses serious public health threat. Poor demographic data collection and storage were revealed thus, computerization of medical records for collection, storage and retrieval of data is imperative for adequate planning and control of measles imperil in Nigeria.

    Full Text Available Small and medium enterprises (SMEs play an essential role in the sustainable development of countries. They help in employment generation, industrial production increase, and export, social enrichment as well as political stability. This study investigates the survival strategies and sustainability of SMEs using selected small businesses in the Oshodi-Isolo Local Government Area, Lagos State. It examines the type of growth strategies that SMEs adopt, ascertains what influences their survival strategies as well as the challenges that hinder their growth. Fifty (50 SMEs were randomly sampled. Their owners and managers were interviewed using questionnaires. Data collected were analysed using descriptive statistics and Pearson product–moment correlation coefficient statistics. Our findings reveal that there is a statistically significant relationship between survival strategies and SMEs’ sustainability. The major implication of the findings is that maintaining small but committed and motivated employees is critical in guaranteeing the survival of the SMEs in a volatile economy. The study recommends that there be a need for orientation and educational programmes to change the mindset of business owners to enable them to graduate from sole atomistic proprietor devoid of modern scientific business practice and effective succession to corporate status with an apparatus of modern business management practices and corporate vision. Finally, the study further suggests some imperatives for policy makers concerned with promoting small businesses’ growth and sustainability in the Oshodi-Isolo Local Government Area of Lagos State.

    Full Text Available Cuba es un país que, además de presentar niveles de fecundidad inferiores al nivel de reemplazo, ha registrado un significativo saldo migratorio negativo. Se observa también un intenso flujo migratorio interno cuyo patrón es muy diferente entre las provincias. Debido a la magnitud de estos flujos migratorios, la migración se presenta como un componente demográfico importante en la dinámica poblacional cubana. De esta forma, el objetivo de este trabajo es estimar el efecto de la migración interna e internacional sobre el potencial de crecimiento a largo plazo de Cuba y de sus provincias. Para esto, calculamos medidas de reproducción y de crecimiento poblacional a partir de los métodos demográficos convencionales y de la metodología propuesta por Preston y Wang (2007, que se basa en los métodos de variable r. Considerando el patrón demográfico corriente, en la mayoría de los territorios de Cuba se observa una reducción substantiva en la capacidad de reposición de las generaciones y en tamaño futuro de la población cuando se consideran los efectos de la migración.
