Multi-label text categorization is an important modern text mining task. The large number of feature in text datasets degrades the performance of text classification. However, multi-label text often has more noisy, irrelevant and redundant features with high dimensionality. A large amount of computational time is required to classify a large number of text documents of high dimensional. The problem is much difficult in Arabic due to complex nature of the Arabic language, which has a very rich and complicated morphology.

Gari is cassava flour widely used in West Africa, more specifically in Benin. The transformation of cassava into Gari involves several stages. The pressing step is one of the steps to remove hydrocyanic acid from the pulp, multiply microorganisms and help increase the palatability of Gari. Pressing equipment is made of metals which negatively impact the environment because their welding requires energy consumption and generates waste (toxic gases, electrode residues and iron filings).

The use of mobile technologies and applications provides teachers a wide range of possibilities, both, in the teaching process and the assessment for learning. Nowadays, there are several applications to support the whole teaching-learning process, such as Kahoot, Socrative, Plickers, Gosoapbox, iClicker, etc. In this context, this paper aims at describing the potential of Quizizz as a valuable tool in education, taking into consideration that the use of quiz-type applications, if well planned, can motivate students, drawing their attention to achieve better results in the classroom.

RFID vehicle parking and payment system using android. The manual work of parking and payment is reduced making it very easy to tag a vehicle by using RFID tracker to identify the user details and deduct amount from his/her wallet. This System makes the work easier such as booking the slot, paying the amount. Whenever the car enters the parking base, the user information in the RFID tag is read by the RFID reader and the starting time/entering time of the user details is sent to the admin.

Choanal atresia is a rare structural abnormality in which the posterior opening of the nasal cavity, which flows through the nasopharynx and the inability to breathe, occurs. The aim of this study is to evaluate the efficacy and results of unilateral or bilateral choanal atresia management using modern endoscopic techniques. The study included seventeen patients who were admitted to the department of Ear, Nose and Throat in Tishreen university, who were underwent surgery for choanal atresia via endoscopic techniques, and study results and complications.

The brown stink bug Euschistus heros Fabrícius (Hemiptera: Pentatomidae) is one of the main pests of the soybean crop. Aiming at the population reduction of this insect, an alternative to chemical control is the association of selective products with biological control through egg parasitoids, such as Telenomus podisi Ashmead (Hymenoptera: Platygastridae). The objective of this study was to evaluate the lethal and sublethal effect of insecticides and phytoinsecticides on adult and immature stages of the parasitoid in pre and post parasitism bioassays and sublethal effects.

The cancer of skin type no melanoma is the most frequent cancer in Brazil and accounts for 25% of all malignant tumors registered in the country. It has high rates of cure if detected early. Among the tumors of the skin, non-melanoma type is the higher incidence and lower mortality. Test bioproducts with protective solar activity is crucial in the prevention of public health and promotes technological development. The study evaluated the influence of Bixa orellana L. oil on SPF (Sun Protection Factor) six emulsions containing chemical filters Eusolex 232 and Neo Heliopan MBC.

Diabetes mellitus (DM) and hypertension (HA) are common diseases and increasing incidence every year, causing severe complications to the individual. Diabetes mellitus occurs when the production of the hormone insulin by the pancreas is insufficient or when the body does not efficiently use the insulin it produces, leading to an increase in the concentration of glucose in the blood. And hypertension is characterized by increased blood pressure level. The objective of this work was the active search for new cases of diabetes and hypertension in the city of Floriano, Piauí.

O objetivo do presente artigo éidentificar e analisar a dinâmica de crescimento da produção agrícola no Estado de Rondônia no período de 1997 à 2016 de três importantes culturas regionais: banana, café e maracujá. Também é enfatizado a análise do maracujá, a partir da verificação das Taxas Anuais de Crescimento da Produção-TACP do fruto especificas por microrregião do estado. A teoria da modernização, na forma do modelo de inovação indutiva, sustentam a construção do estudo. Além disso, para identificação das TACP das culturas, empregou-se o método shift-share.

The water hyacinth is an aquatic macrophyte plant considered as lignocellulosic biomass. The chemical composition of the water hyacinth is presented in considerable contents of cellulose and hemicellulose, and low levels of lignin, which constitutes a potential substrate for the production of ethanol. The present study aims to develop a technology for the production of ethanol of the second generation from the biomass of aguapé.
