<p>La almendra de copoazú como producto promisorio para la industria de cosméticos, chocolate, bebidas, licores y conservas, se evaluó el proceso de fermentación variando el tiempo de remoción de la masa (24 y 48 horas) y la pulpa inicial (30 y 100%). Se tuvieron en cuenta las condiciones de los productores en el acceso a equipos de despulpado. Se cuantificó la temperatura de la masa en tres puntos (superior, medio e inferior), acidez, pH, humedad, prueba de corte y análisis sensorial. Se encontró bajo desarrollo de la temperatura de fermentación en los tratamientos con 100% de pulpa y se registraron las máximas temperaturas entre 35 y 36°C que indican deficiencias en el proceso; no se alcanzó los 40°C requeridos para la muerte del embrión. El 30% de pulpa inicial y la remoción cada 24 horas por 9 días, fueron las mejores condiciones encontradas. La optimización con 0,1% de levadura (Saccharomyces cerevisiae) aumentó la temperatura de fermentación hasta 44°C, los granos fermentados hasta 56,14% y el mayor desarrollo de sabores frutales con intensidad de 4, mostrando un mejor proceso de fermentación. El panel sensorial mostró que los licores de copoazú tienen notas frutales destacadas y bajos valores de otros sabores evaluados. Los resultados son semejantes a los cacaos criollos, conocidos en el mundo como materia prima de licores finos y de aroma.</p><p> </p><p><strong>Fermentation of the copoazu kernel (Theobroma grandiflorum [Willd. ex Spreng.] Schum.): Assessmente and process optimization</strong></p><p>The fermentation of copoazu kernels (a promising product for the cosmetics industry, chocolate, beverages, liquors and preserves) was evaluated varying the time of mass removal (24 and 48 hours) and the initial pulp (30 and 100%). This study took into account the degree of access the producers had to pulping equipment. We quantified temperature of the mass at three points (top, middle and bottom), acidity, pH, moisture, cutting test and sensory analysis. The observed temperatures during fermentation in the treatments with 100% pulp reached a maximum range between 35 and 36°C which indicated deficiencies in the process as the 40°C required for the death of the seed was not attained. Thirty percent initial pulp with removal every 24 hours for 9 days yielded the best results. Optimization with 0.1% yeast (Saccharomyces cerevisiae) increased the fermentation temperature to 44°C, augmented fermented beans to 56.14% and saw a development of fruit flavors with an intensity of 4, demonstrating a better fermentation process. The sensory panel showed that copoazu liquors have outstanding fruity notes and low levels of other evaluated flavors. The results are similar to the criollo cacao, known worldwide as a raw material for fine liquors and fragrances.</p>

Biomass has a large share in the energy generation matrix, due to the regional economic benefits. This work has as main objective to evaluate the parameters used in the manufacture of briquettes produced with forest residues and the economic engineering for the manufacturer. The forest residues were: wood chips and chips of Eucalyptus spp. and barks of Pinus taeda. The evaluations were the chemical characterization of forest residues and the costs involved in the briquetting process. The forest residues presented extractive chemical composition and lignin. The production costs of the briquettes were affected mainly by the equipment, being the Pinus taeda barks the one that presented higher production cost. However, the production costs obtained in this study are approximately 20% lower than the production costs using traditional methods for forest firewood. The energy value from biomass allows the reduction of the dependence of energy, which can be used for the generation of steam or electricity, for subsistence. A fact for energy conversion is to evaluate the material moisture. It is suitable to burn residues with moisture between 45 to 55%. The consumed electric energy is important to evaluate the total costs. The energy required depends on the quality of raw material and the system employed. Forest residues is an important source for eco firewood production, contributing to energy generation and decreasing of the solid waste stored at the company. In this way, the new parameters for briquetting biomass forest wastes shown in this work, which is an important stage of the process, make economically viable and environmentally suitable the eco firewood production.

The content and structure of mental representation of economic crises were studied and the flexibility of the structure in different social contexts was tested. Italian and Swiss samples (Total N = 98) were compared with respect to their judgments as to how a series of concrete examples of events representing abstract indicators were relevant symptoms of economic crisis. Mental representations were derived using a cluster procedure. Results showed that the relevance of the indicators varied as a function of national context. The growth of unemployment was judged to be by far the most important symptom of an economic crisis but the Swiss sample judged bankruptcies as more symptomatic than Italians who considered inflation, raw material prices and external accounts to be more relevant. A different clustering structure was found for the two samples: the locations of unemployment and gross domestic production indicators were the main differences in representations.

This article presents the rationale and methodology for developing an intrinsically safe device, namely, a hydrostatic fiber optic sensor with a position-sensitive detector for monitoring the level of oil products in large-capacity tanks at oil depots and during pumping in a raw material warehouses. This device suitable for continuous monitoring of the liquid level, based on the measurement of a hydrostatic column of liquid with automatic offset of changes in the density of the liquid. Offset is carried out by means of a displacer (a fully submerged float), inside which a housing with a position-sensitive detector (PSD) is integrated. Theoretical validation of the bellows suspension usage for a displacer is given. During filling a container with a liquid whose level is measured, liquid bellows, the movement of which is recorded by an optical triangulation sensor using the reflected infrared ray incident on the bottom of the bellows. The principle of the triangulation sensor operation is based on the geometric properties of the triangles. The pulses of infrared radiation come through a fiber optic cable. In order to measure the movement of the surface (the bottom of the bellows) by measuring the movement of the reflected beam, a position-sensitive detector is used, which is located in a remote controller. In this device for the intrinsic safety problem solution, optical inputs of a fiber optic flat cable are located in the active zone of the sensor, which is connected to the optical inputs of a position-sensitive detector, operated on the principles of photoelectric effect. The light spot moving along the sensitive zone and converted by the detector into a one-dimensional signal proportional to the distance to the object. hydrostatically applies pressure over the entire effective area of the measuring

Because of the almost-instant connection with the welfare and well-being of individuals, pharmaceutical industry stands prominently as a very important factor for the improvement and progress of a healthy productive nation. These days, pharmaceutical industry thrives as one of the largest and exponentially expanding global industries. Nonetheless, millions of people in low income developing countries, have to suffer from the fatal consequences of the inaccessibility and non-availability of essential drugs. This is also happening in Yemen, where the pharmaceutical manufacturers sector have to face up to many challenges. The Yemen Drug Company (YEDCO) was founded in 1964 by the Yemeni government as it collaborated with private investors. It was endorsed as a company with the expertise in the medicinal drug marketing. YEDCO started its work by taking in drugs from foreign companies and then locally marketing and distributing them. In 1982, YEDCO built the first medicinal factory for drugs in Sana’a. Since then, seven companies were set up to manufacture medicines in Yemen. The expanding population has led to the need to have more pharmaceutical products. It may be understandable that pharmaceutical manufacturer companies are also hit by the political crisis in the country. Inadequate amount of fuel and raw material as well as low security status were some of the underlying factors behind these ill-effects in Yemen. Imported drugs make up about nearly 90% % of the pharmaceutical market compared to 10% drugs from the domestic market. This situation has led to an additional burden being shouldered by the national economy, where Yemen spends about US$263 million annually on pharmaceutical drugs, in reference to the national Supreme Drugs Authority. Although there is a very quick growth in the population and drugs consumption, the pharmaceutical industry has not been very active, where global pharmaceutical products play their role dominantly on the domestic market. The pharmaceutical production necessitates skilled human resources like university graduates. By contrast, the government and the private sector should also motivate the pharmaceutical industry and make use of the local employment
