Aim: This study was conducted to compare the effect of manual hyperinflation and rib springing technique in mechanically ventilated patients with lung collapse. Martials and methods: forty mechanically ventilated patients with lung collapse who were admitted to the intensive care unit participated in this study. Their ages ranged from 30 to 40 years and randomly distributed into two equal groups: group (A and B).

This study aims to identify the factors that underlie the difficulties in the teaching-learning process of Statistics Applied to Education at ISCED-Cabinda and at the Higher Pedagogical Social Sciences Arts and Humanities Institute of M’Banza Congo.

In order to introduce the planting and cultivation of Bougainvillea spectabilis in Jianghan area, domesticate the varieties that can adapt to the climate of Jianghan plain, improve the market competitiveness of B. spectabilis and make it more widely popularized. A comparative experiment on overwintering cold resistance was carried out with six Bougainvillea varieties introduced from Yunnan, China. By comparing the freezing injury degree of B.

Heart failure is a complex clinical syndrome in which structural or functional cardiac disorders result in an impaired cardiac function causing symptoms that vary according to the underlying pathology of heart failure. Patients with heart failure are often challenged by the loss of independence and compromised functional abilities associated with the symptoms. This is why comprehensive cardiac rehabilitation including supervised exercise is advised.

Objectifs spécifiques: Suivre la production de la spiruline dans trois bassins de 100 m2 pendant 10 jours et analyser les qualités nutritionnelles et microbiologiques de la spiruline.

Introducción: El cáncer de próstata (CaP) es la proliferación descontrolada de las células epiteliales (secretoras luminales, células basales o células neuroendocrinas) de la glándula prostática, maligno y con pronóstico heterogéneo relacionado principalmente a la edad, grado grupo, nivel de Antígeno prostático especifico (APE), tipo de cáncer, duplicación del APE, hallazgos quirúrgicos, entre otros.

Introducción: La sospecha de cáncer de próstata se da por alguna alteración en la consistencia de la próstata, al realizar el tacto rectal o por elevación de las cifras del antígeno prostático específico (APE), o ambas, ante lo cual deberá realizarse una biopsia transrectal guiada por ultrasonido (BTRUS)de próstata, con el fin de enviar las muestras a patología y recibir un reporte histopatológico que clasifique a cada uno de los pacientes en los diferentes grados de riesgo, de acuerdo a la escala de Gleason y por consiguiente iniciar un tratamiento de manera oportuna.

Sinus bradycardia is established as a heart rate less than 60 bpm. This can be normal in young, healthy adults or in patients taking blocking agents. It is considered pathological if it produces a decrease in cardiac output and presents symptoms. The conduction abnormality can occur at the level of the sinus node, atrioventricular node tissue, or the specialized His-Purkinje conduction system.

This article was developed with the purpose of presenting a methodological alternative for the teaching-learning process of indefinite integrals using Maple mathematical assistant at the 1st year of Mathematics Teaching course at ISCED-Cabinda, in order to minimize the difficulties found at this level such as students’ lack of motivation in relation to the mathematical content taught in the traditional classroom, the failure to achieve satisfactory results intended in the teaching of indefinite integrals, incomprehension of the concept of indefinite integrals, the lack of mention about the

In urban and peri-urban areas, wastewater and sewage sludge are used without prior treatment to fertilise vegetable soils. To this end, sewage sludge treated with market garden waste was tested to evaluate the morphological performance and yield of tomatoes. Thus, the composts based on faecal sludge and market garden waste are T0, T1 and T2 (for respectively T0: composted faecal sludge alone, T1: compost with 2/3 faecal sludge and 1/3 market garden waste and T2: compost with ½ sewage sludge and ½ vegetable waste).
