Abstract: Dentre as pragas que atacam a cultura do coco (Cocos nucifera), destaca-se o ácaro da necrose, Aceria guerreronis. Esta praga danifica os frutos nos primeiros estágios de desenvolvimento, podendo acarretar perdas parciais ou totais na produ o de frutos. Este trabalho teve como objetivo avaliar o efeito de medida química e cultural no controle de A. guerreronis, visando à utiliza o dessas duas medidas em um programa de manejo dessa praga. O trabalho foi realizado em Petrolina-PE, no período de agosto a dezembro de 1999. Foi utilizado o delineamento em blocos ao acaso, com quatro tratamentos e quatro repeti es, sendo cada repeti o composta por duas plantas da variedade coco-an o verde. O trabalho foi composto pelos seguintes tratamentos: A -- plantas com limpeza e sem tratamento químico; B -- plantas com limpeza e com tratamento químico; C -- plantas sem limpeza e com tratamento químico; D -- plantas sem limpeza e sem tratamento químico (testemunha). Na limpeza das plantas, retiraram-se todos os frutos danificados pelo ácaro da necrose, repetindo esta etapa por três vezes. Utilizaram-se os produtos fenpyroxymate, tetradifon e surfactante, em mistura, na dose de 200ml, 300ml e 15ml, respectivamente, para 100 l de água. Foram realizadas três pulveriza es com intervalos de vinte dias. Os resultados mostraram que a utiliza o das medidas cultural e química, de forma individual, apresentou uma eficiência de 26% a 87% e 64% a 89%, respectivamente, no controle do ácaro. No entanto, a associa o dessas duas medidas de controle apresentou um efeito sinérgico com eficiência de 87% a 96%.

Abstract: Introduction: Epidemiologic researches about psychoactive substance use have shown an up-and-coming situation to abusive consumption of alcohol in adolescent and young-adult groups. This consumption over come the knowledge about damage caused by abusive of these substances, especially for the population part who is in the “top of life experiences”; the university students. Aim: To estimate the prevalence of the alcoholic ingestion and alcohol abuse in university students at Jequié-BA, and to verify the association between the alcoholic ingestion and alcohol abuse with the gender, race, smoking and graduation area. Methods: Prevalence study with probabilistic randomized sample (n = 129) of a population of 3,644 university students, registered in three universities. It was used a Questionnaire contends socio-demographic data, asking for the alcoholic ingestion and test CAGE to abuse. Results: It has been found prevalence of 63.6% to alcohol ingestion, 21.7% of high risk in abuse, and 8.5% of alcohol abuse. Although they have not been gotten association statistics between these variable and gender, race, graduation area and smoking; the data had demonstrated highest rates of alcohol abuse, and high risk in developing in students of masculine gender, medium brown race, who attend a graduation course in the health area. Those who have used of the tobacco had presented percentile greater of high risk in becoming alcohol consumer abusive. Conclusions: Intent for data found, as much alcohol ingestion as abuse, since they reflect the necessity of prevention politics to the alcoholic abusive ingestion in this population

We investigate Gaver’s parallel system attended by a cold standby unit and a repairman with multiple vacations. By analysing the spectral distribution of the system operator and taking into account the irreducibility of the semigroup generated by the system operator we prove that the dynamic solution converges strongly to the steady state solution. Thus we obtain asymptotic stability of the dynamic solution of the system.

Abstract: O uso do biossólido na agricultura tem-se mostrado a melhor alternativa ambiental e econ mica para o destino do lodo de esgoto. O objetivo deste trabalho foi avaliar o potencial nutricional do biossólido para produ o de mudas de pinh o-manso em tubetes. O experimento foi realizado em casa de vegeta o tendo, como substrato, esterco bovino, vermiculita e biossólido. O delineamento experimental foi o de blocos casualizados com três repeti es em esquema fatorial 5 x 2, correspondendo às concentra es de biossólido no substrato (0, 10, 20, 30 e 40%) e ao tratamento ou n o das sementes de pinh o-manso com fungicida. Aos 60 dias foi realizada análise foliar. Relativo às concentra es de biossólido verificou-se efeito significativo para os macronutrientes N, P, Ca, Mg e S e micronutrientes B, Cu, Mn e Zn. O tratamento de sementes teve efeito significativo para o Zn. As folhas apresentaram concentra o de macronutrientes com a seguinte ordem: N > K > Mg > Ca > P > S. O acúmulo de micronutrientes apresentou a seguinte ordem: Fé > Mn >Zn > B > Cu. Há grande contribui o do biossólido nos teores de nitrogênio, enxofre e micronutrientes foliares, em plantas de pinh o-manso. The use of biosolids in agriculture has proven to be the best alternative for the environmental and economic destination of sewage sludge. The objective of this study was to evaluate the nutritional potential of biosolids to produce jatropha seedlings in polytube. The experiment was conducted in a greenhouse using as substrate manure, biosolids and vermiculite. The experimental design was in randomized block with three replications in a 5 x 2 factorial, corresponding to the substrate concentrations in sewage sludge (0, 10, 20, 30 and 40%), and the treatment or not of the seeds of jatropha with fungicide. At 60 days, leaf analysis was performed. Regarding the biosolids concentrations, significant effect was verified for the macronutrients N, P, Ca, Mg and S, and for the micronutrients B, Cu, Mn and Zn. The seed treatment had a significant effect for Zn. Leaves showed concentration of macronutrients in the following order: N > K > Mg > Ca > P > S. The accumulation of micronutrients presented the following order: Fe > Mn > Zn > B > Cu. There is a great contribution of biosolids for the contents of nitrogen, sulfur and micronutrients in leaves of jatropha plants.

This study centred on understanding how local communities participate in tourism industry in Bwejuu Village in Zanzibar and the benefit they are getting towards poverty reduction. Specifically, the study identifies tourism industry activities and how local communities participate in improving their livelihoods, find out factors influencing local community participation in tourism sector and lastly, and identify contribution of tourism sector in enhancing local communities’ livelihoods. Interviews, observations, documentary reviews and photograph taking are methods employed to the case. The study result shows that tourist hotels, beach, seaweed, historical building archives, diving and snorkeling, sailing boats, coral reefs and lagoons as well as mangrove swamps are some tourist activities in the settlement. Both men and women involves in the tourist activities. The tourist activities noted contributing to local communities’ livelihoods in terms of employment creation, leisure, income generation, increased government revenues, schooling, health, house construction and household consumption. However, language barriers, inadequate experience of operators, poor education and training, culture, commitment of actors and poverty level are some constraints highlighted. Following these challenges, the study recommends that the government in collaboration with other development partners interested in tourism industry development may opt to ensure capacity building to local communities and tourist operators in Zanzibar, to review the policy and legislations in place as well as to encourage stakeholder involvement in Tourism sectors as prospects for its development. In conclusion, it can be asserted that if tourism developers believe that local communities will be satisfied if they are used as labourers instead of being ownership of tourism activities. Thus, there is an urgent need to enhance participation and involvement of local communities in tourism sector. These communities must be actively
