The study endeavors to investigate the determinants of mobile phone usage (adoption) using data from Central Region in Eritrea. Data were collected by distributing questionnaire to a sample of 450 individuals selected at random using the accidental technique. A close ended questionnaire was used and the questionnaire captured individual characteristics and views on the use of mobile phone. The questionnaire was administered over a period of twelve weeks. Many and very significant conclusions are derived from this research. It has been found that the majority of respondents use the mobile phone; the main reason for having a mobile is because they want to have it; the most important reason for having a mobile phone is to easily communicate with friends or relatives; the main purpose of using mobile phone sets always are making local calls. It is also interesting to note that some respondents never used their mobile for sending text messages; perhaps this is related with the illiteracy rate in the country. The findings show that certain variables such as gender and income are important predicators of mobile usage in Eritrea. The empirical results show that age and educational level were not significant in explaining variations among mobile users.

The objective of this paper is to determine what factors stimulate or hinder the adoption and usage of the Internet by analyzing data collected from 300 respondents from the city of Asmara, Eritrea in the year 2017. We adopted a micro-econometric approach (Multinomial logit model -MNL) and the paper identifies six significant determinants and estimated their impact with the help of econometric tests. The results show that internet users in the city of Asmara tend to be young and in better living conditions. The probability of using the Internet is also higher for people with better English ability and for individuals’ who have better computer savvy. Moreover, Internet users are more likely to have close family members and friends who also use the internet. These results provide evidence of not only digital divide in the Internet access, but also in the usage patterns in the city.

The objective of the study was to determine the hatchability rate of African cat fish eggs under artificial condition in Adamawa State, the guinea savannah zone of Nigeria. The female fish was artificially induced using ovaprim at 0.2ml in the cool hours of evening. The eggs were stripped in the morning hours after 12 hours of stimulation and were fertilized externally with sperms collected from the male fish. Fifty percent (50%) of the eggs were observed to have hatched successfully within 12 hours though; the entire system ran out of water supply in the middle of the night. This led to the death of all the fry and prevented all the other eggs from hatching resulting to 0% fingerlings. The quality of water used was not ascertained because, it was not tested and the source unknown. The climatic conditions were observed to be favourable because, the work was performed during the raining season between August and September, 2017. It was observed that, in most of the African catfish hatcheries, fry ‘come out’ from eggs under an artificially controlled condition in commercial numbers. Water quality forms part of the most important factors in achieving high hatchery success rate. These fry grow into fingerlings and they later become juveniles. These fry need consistent good food provided in sufficient quantities at regular intervals for smooth transitional growth. A lot of uncertainties have been linked to the propagation of African Catfish and this may be probably due to inadequate knowledge of the fish. Therefore, a successful hatchery relies on efficient facilities and equipment that match excellent up to date technical know-how, standard procedures, and dedicated and skilled personnel.

Objective: The chikungunya fever is an arbovirus transmitted by chikungunya virus (CHIKV), using vectors like mosquitoes Aedes albopictus and Aedes egypti. This review aimed to gather up to date and official information on the Chikungunya fever in Brazil because of its resemblance to dengue and importance for public health. Methods: A review of scientific literature was conducted by searching articles in the mains databases, NCBI, SCIELO, BIREME, CAPES periodical portal between months February and April 2015. Results: Joint pain are the classic symptoms of chikungunya, and are being used as one of the clinical, laboratory and epidemiological for differential diagnosis. There are no vaccines for the disease, and palliative drugs used against inflammatory response caused by the virus. Mosquito control is the main preventive measure. Thus, it is necessary that the health workers are trained for the effective diagnosis and prevention.

Hadamard Matrices and M-Sequences (which formed a closed sets under the addition and with the corresponding null sequence formed additive groups and generated by feedback registers) are used widely at the forward links of communication channels to mix the information on connecting to and at the backward links of these channels to sift through this information is transmitted to reach the receivers this information in correct form, specially in the pilot channels, the Sync channels, and the Traffic channel. This research is useful to generate new sets of sequences (which are also with the corresponding null sequence additive groups) by compose Hadamard matrices and M-sequences with the bigger lengths and the bigger minimum distance that assists to increase secrecy of these information and increase the possibility of correcting mistakes resulting in the channels of communication.

This experiment was designed to scrutinize effects of inclusion of Gum Arabic versus egg yolk in either fresh or frozen extender for Herri ram’ semen on subsequent pregnancy rate. Semen ejaculates were collected from two rams. Two trials were attempted. Trial I, semen ejaculates were diluted with freshly prepared extenders either contained 10% EY (Control) or 6% GA (GA). Ewes were randomly selected and subdivided into 2 groups and inseminated. Trial II, extenders were frozen (-20°C) for 30 days before using, thawed and semen ejaculates from same rams were diluted and used in inseminations. Ewes were subdivided into 2 groups and inseminated with semen diluted in either control or GA6 extender. Results revealed that using fresh extender surpassed frozen one in achieving better pregnancy of the artificial insemination. Pregnancy rate derived of inseminations prepared by GA6 extender was significantly higher (P

The main objective of the study was to investigate the pains and challenges of widowhood in Adamawa State, Nigeria. The data was collected through the use of questionnaires and oral interviews. Data generated were analyzed using descriptive statistics. The results show that, majority of widows in Adamawa State are still young and sexually active with high reproductive tendencies that are within the age brackets of 20-30 (46.3%). Margi tribe had the majority (22.7%) widows who are mostly Christians (49.3%) with tertiary educational level of 31% and entrepreneurship of 37.3%. It was gathered that, 36.0% of widows had their marriage lives full of joy and happiness with high future expectations before the death of their husbands. The results also show that, 56.0% of the widows suffer greatly in processing the benefits of their deceased husbands. The findings show different levels of maltreatment experienced by widows across the state. It has been established that, at the initial stage of widowhood, most widows go to the cold shell of their homes to fight loneliness. Thus, the study would be of immense benefit to widows who are in need of practicable opportunity to reduce their pains and challenges. This is imperative, because the age-long cultural conception of marital expectations now seems inadequate for present day widows who have to grapple with new and multiple roles of breadwinning, physical protection, custodian of societal morality as well as caring, feeding and educating their children (most times all alone). The findings would be useful to the government, scholars, policy makers and opinion leaders in matters related to widows. Above all, professional counselors could benefit from the study in playing their roles as crisis managers and providers of relief materials to widows. On the basis of this awareness, counselors would be adequately equipped to counsel the widows, their…

This study was conducted to determine the consumers understanding regarding the food labels in the dairy products and to find out its utility in consumers daily life. Primary data was collected by interviewing 200 consumers (NDRI and GADVASU milk parlor), who were the regular consumers of the milk products in the two distinct areas of northern India to find out the differences in their purchasing pattern. The result revealed that majority of the consumers reads the food labels on initial purchase of their food items. Consumers were well comprehended with the food labels used in the food items. Different kinds of information like Expiration Date (99.50%), Ingredients (78.40%), Health claims (66.80%) and Nutritional information (65.30%) were mostly used by the consumers, and they look for it in the dairy food products labels. Expiry Date was most commonly used by consumers as an indication of freshness, shelf life and food safety across a range of foods. The findings proposed the improvement of consumers knowledge regarding food labels used in the dairy products.

Each art period or movement has been an effective form of expression for its time and mostly emerged as reaction to the previous art movement. This study discusses the emergence cubism as a form of artistic expression and its style through the works and examines the composer Igor Stravinsky’s Rite of Spring in the context of cubism. For cubism, the deformation of the usual, objective order of the universe appears as an inevitable mandatory principle. With this movement, it is possible to reshape the form in different ways through formlessness, to distort all and reincorporate all known forms and achieve new forms. In the heart of cubism, there lies the principle of expressing the idea of imagining and describing the things that happen in separate places together as if they are happening at the same time, by combining it with the pleasure of confusion. Cubism is a window opening to modern art and the most important step taken on this path. The influences of cubism have manifested themselves in the different musical structure of Stravinsky’s Rite of Spring. His music (the main theme) has been built on a rhythmic structure that can be defined as complex. The spontaneous and intuitive and impulsive reflection of artist’s impressions regarding the object, is evident in the intuitive rhythm, chord and unique texture of Stravinsky’s work. It is expressed that there is no intellectual system used in the formation of the harmonic language of the “Rite of Spring”, that it is only based on inner perception.
