The health effects of the Opuntia ficus indica fruits are reported in the literature: protective actions against oxidation, cancer and cardiovascular troubles. But, few researches about the transformation of these nutritive fruits are available; we studied therefore the pulp characteristics and the processing of a local variety to produce nectars. \n The pulp had an average pH of 5.64, 13.47 °Brix, with total sugars (106 g L-1), K (1180 mg L-1), 503.3 µg L-1 of β carotene, 120 mg L-1 of total phenolic compounds, 4.9 mg and 46.9 mg L-1 respectively for betacyanins and betaxanthins and 243.4 mg L-1 of Vitamin C. The formulated nectars with 35% of pulp (N35) and 45% of pulp (N45) had respectively 14 and 15 °B. Minor components represent 1109 mg L-1 and 1112 mg L-1 of K for N35 and N45 respectively, lycopene 125.4 and 133.8 μg L-1, respectively, β carotene (318.6 μg and 362.8 μg L-1), and vitamin C 227 mg L-1 and 231 mg L-1. \n We confirmed the stability and acceptability of these beverages after a month of storage; and we suggest that the pulp processing is a new form of use to be applied at the agro industrial level.

As social networking has spread, people started to share their personal opinions and thoughts widely via these online platforms. The resulting vast valuable data represents a rich source for companies to deduct their products’ reputation from both social media and crowds’ judgements. To exploit this wealth of data, a framework that aims to collect reviews and rating scores respectively from social media and crowdsourcing platform to perform analysis, provide some insights about targeted products/services and give consumers’ tendencies. The sentence-level sentiment classification is a text classification problem based on sentiment analysis followed by subjective classification; so the extracted opinions can be divided into different sections: positive, negative and neutral. During the analysis process, a consumer category, known as strict (leaders), is usually excluded from the process of reaching a majority consensus. To separate their opinions from the majority, a fuzzy clustering is used to compute consumers’ credibility. The key novelty of our approach is adding a new layer of validity check using a crowdsourcing component that ensures that the results obtained from social media are actually supported by opinions extracted directly from real-life consumers. Considering the large amount of available data, our framework is built on top of the Hadoop MapReduce architecture which allows us to handle these data with efficiency. Finally, a set of experiments, where Twitter and Facebook are used as data sources, are carried out to validate this model. The obtained results show that our approach is efficient and more accurate compared to existing solutions mainly thanks to our two-layer validity check design.

This paper presents an initial investigation of secret raw key generation rates and maximum achievable distance for multi-photon three stage tolerant protocols. In this paper, coherent non-decoying quantum states are used to transfer the encoded bits from Alice to Bob. We calculated the optimum average number of photons at which the secret date rate is maximum and then calculated the maximum possible distance that can be achieved at these optimum values. It was found that for the three stage protocol under investigations that the maximum distance that can be achieved is around 200 km at a maximum number of photons of 12, above this the change to the maximum distance is insignificant

La Responsabilidad Social Corporativa (RSC) es el conjunto de obligaciones de los empresarios para tomar decisiones congruentes los objetivos y los valores de nuestra sociedad. En este sentido, cuando las empresas presentan RSC están mostrando, más allá de los beneficios económicos, conciencia social. Así, pues, este trabajo deposita el interés en conocer si las empresas andaluzas muestran RSC y, en caso afirmativo, qué aspectos son determinantes en las mismas. A nuestro entender, es un tema de interés porque las empresas deberían mostrar un compromiso social, ya que, según señala Wood (1991) los empresarios parece que no siempre muestran comportamientos responsables con la sociedad. Para ello, se diseñó un cuestionario, que refleja una fiabilidad adecuada (alfa de Cronbach de .532), el cual se aplicó a 365 personas pertenecientes a diferentes sectores. Los resultados reflejan el interés que muestran las empresas andaluzas pertenecientes a distintos sectores en la RSC, además los hallazgos obtenidos permiten conocer cuál es el aspecto clave en cada sector. Por otro lado, los datos obtenidos resaltan la relevancia de usar herramientas que permitan el control de riesgos ambientales. En este sentido, los datos apuntan a la necesidad de continuar trabajando dentro de esta línea, para conocer, principalmente, los elementos que impactan negativamente en nuestra sociedad con una mirada preventiva o proactiva.

Undoubtedly, urban development has a strong environmental impact. One of them, it is the urban heat island (UHI) phenomenon that appears in cities for the drastic change in land use. This phenomenon affects thermal comfort index harming health and human productivity. To counteract this effect, air conditioning systems are used, leading to an increase in energy consumption. Mexico, as a country where almost all the world\'s climates are present, the UHI mitigation becomes a great challenge since the solutions that can be achieved may be adequate for a city but not for another. In this work, a particular point of view is presented on the strategies to follow to solve this problem in a developing country, with a chaotic urban growth and climate complexity.

OBJECTIVES: To evaluate the association between RECQL gene mutations and breast cancer risk by meta-analysis.\nMATERIALS AND METHODS: We systematically searched PubMed and Web of Science. Two reviewers independently evaluated the eligibility of publications and consensus was achieved. We extracted data to calculate the relative risk and Odds ration with the corresponding 95% confidence intervals using forest plots and I2. RESULTS: Six eligible studies comprising about 21,165 patients with breast cancer and 16,620 control cases were selected. Our study shows statistically significant positive association between RECQL gene mutations and breast cancer risk, with RR of 4.03 (95% CI: 2.13-7.62) and OR of 3.94 (95% CI: 2.25-6.89). CONCLUSION: These informations may be of practical value and further researches of RECQOL gene mutations and breast cancer risk relationship among high-risk group persons, especially in BRCA1/2 mutation-negative breast cancer patients, are necessary. Moreover, larger cohort studies based on different population-types are needed to determine RECQL genes role in the pathogenesis of breast cancer.

A key challenge facing schools is that of truancy among school going age children. It is imperative that factors contributing to learner truancy need to be investigated as they impact negatively on learner performance. The dynamics initiating learner truancy may be rooted in socio-economic conditions, school related and prolonged factors. This needs to be addressed so that governments and different stakeholders might intervene to curb the problem. If this problem persists it might lead to learner dropout. A lack of parental involvement, bullying and punishment for late-coming are some of the reasons why there is a high rate of truancy in schools. Learners who choose not to attend school regularly and who exhibit patterns of extended absences are in violation of the law and are therefore, the focus of many school systems. Truancy often occurs in high numbers due to chronic illnesses and family crises, but these absences are not what offer the most concern to schools. Unexcused absences are the core of the problem being addressed not only nationally, but also in other countries that have compulsory school attendance laws. Unexcused absences often fall under the term of truancy.

Purpose of this paper is to describe the possibilities of music therapy in the context of Integrated Psychotherapy / Knobloch. The main pillar of music therapy in the process of Integrated Psychotherapy / Knobloch is created by Interpersonal Hypothesis of Music, which is based on an idea that the music reflects interpersonal tendencies which independent observer can determine with the certainty beyond a mere chance. Music is able to induce a state that similarly like dreams activates interpersonal processes in person’s Group Scheme, and in fantasy even satisfies some interpersonal needs and activates interpersonal tendencies. This relates to all people alike. One of the most important tools of music therapy is Circumplex that represents eight categories of interpersonal tendencies (dominance and submission, affiliation and autonomy, exhibition of high and poor quality, fight and escape). There are also used various techniques of passive (receptive) and active components of music therapy – always in accordance with the principle of Interpersonal Hypothesis of Music which together with the Circumplex and Group Scheme can function as effective secondary tool in therapeutic practice.
