This particular paper has been focused on the multiple discriminations suffered by women and on the problems that they face in the field of refuging and immigration, as recorded to a large extent through informal interviewing of public agencies staff that are involved in this issue. Migrant women are described as “exclusion within the exclusion”, while pointing to the efforts of public agencies in European Union and especially Greece, such as the General Secretariat for Gender Equality, to address the problem.

In the present work an analysis was made of the formation of crusts or rings in clinker kilns of cement factories in Cuba and Argentina because these formations are one of the most serious problems presented by the kiln areas, which bring with them, stops unnecessary of the entities. With the use of phenomenological models, general parameters were determined, as well as several residence times of the ovens, as appropriate. In addition, several balances were made in a general way and specifically in several scenarios with the Matlab software in function of the different compounds that enter the furnace or that are formed within it, taking sulfur and sodium as main substances of study, in order , to determine several aspects of them, such as: their influence on the formation of the rings, the quantities present in the system, their main reactions, their behavior in normal operating contexts and in conditions of instability, as well as possible solutions for its mitigation and control in kilns. The calculations showed that sulfur and sodium should be managed close to the parameters established by the entities for a good operation of the ovens, thus avoiding unnecessary stops due to ring formation.

Until recently, Biology explained the socially “normal”, in the Social Sciences as well. The biological difference (and the different anatomical characteristics) entailed the difference of roles according to Sex (male, female) and influenced the perception that each person had for himself/herself (“biologization”). During the last years, the “de-biologization” of the sciences has essentially been achieved, including the science of Linguistics, by introducing into them the analytical category of “gender”. Since the 1980s, the counterbalance between biological and social gender was disputed and it was argued that gender is exclusively a construction of society and culture. A strong opinion, in the context of the above construction, is that the Discourse and language reflect hierarchical/empowering social realities, which are not “innocent” towards gender inequalities and discriminations. Consequently, the grid of predominant gendered prejudices and stereotypes is reproduced and perpetuated through them, depending on the historical and cultural conditions. A concise historical review of that issue is presented in this paper.

Ovarian carcinoma was believed to had arised from fallopian tubes and then spread to ovarian surface and peritoneum. In addition, Lack of ovarian lesion precursor identified and the fact that bilateral salphingo-Oopherectomy performed to protect women with BRCA mutations from ovarian carcinoma lead many authors postulated that fallopian tube is probably the origin of serous ovarian carcinoma. Lately, initial form of serous carcinoma in fallopian tubes of women with BRCA mutation has been identified and this precursor lesion is known as STIC (serous tubal intraepitelial carcinoma).Prophylactic BSO in high risk women (with BRCA mutation) after completed parity may reduce risk of ovarian carcinoma dramatically (80%). Meanwhile, prophylactic salpingectomy as an alternative may suffice to prevent ovarian carcinoma if we could ensure that serous ovarian carcinoma arise from tubal fimbriae.

Hydrosalpinx is a fluid-filled distension of the fallopian tube with concurrent distal tubal occlusion.Hydrosalpinxassociated infertility is supposed to be treated only by IVF. Furthermore, salpingectomy plays a crucial role prior to IVF and scientific evidences have shown that it may improve pregnancy outcomes compared to functional surgery by removing the toxic effects of hydrosalpinx. However, functional surgery may be the excellent option in developing countries or in cases with specific characteristics. Functional surgery (i.e. fimbrioplasty, salpingostomy, microsurgical tubocornual anastomosis) may be amenable to performed in hydrosalpinges. Fimbioplasty, salpingostomy, and microsurgical tubocornual anastomosis may increase pregnancy rate by 53%, 30%, and 80% respectively. Thin-walled hydrosalpinges with mucosal adhesions had a higher rate of tubal pregnancy, whereas thick-walled hydrosalpinges with fibrosis of the wall were not compatible with normal pregnancy. Functional surgery is, therefore, indicated in patients with thin-walled hydrosalpinges with minimal or no mucosal adhesions.Studies have shown that laparoscopic salpingectomy improves IVF outcomes. It should be performed only when hydrosalpinges are unable to be repaired or in cases of IVF failure. Functional tubal surgery should be preferred to salpingectomy in milder forms of tubal disease or in developing countries. Proper assessment of tubal mucosa of hydrosalpinges should be performed prior to surgical treatment as this will prevent mis-management of patients.

The work had as object of study the process of integration of Higher Education in Cuban municipalities, due to the novelty of it and the lack of management tools to carry it out. A historical study was made of the process of universalization of Cuban Higher Education with its particularities in the Calixto García municipality of Holguín province, Cuba; all of it constitutes an instrument of invaluable value for the historical, logical and prospective studies related to this subject. The objective of the research was to demonstrate that the integration process of Higher Education in the municipality of Calixto García was successful from the implementation of a procedure for this purpose and the evaluation of the results in basic indicators of the substantive processes before, during and after the integration. Theoretical, empirical and statistical methods used during the research process. The procedure constitutes a theoretical-practical contribution to the process of conception and organization of the integration of Higher Education in the municipalities and at the same time, it is an important methodological and organizational instrument. Its application corroborated its effectiveness and relevance when a significant increase in quality detected in the main indicators of the substantive processes in the Calixto García Municipal University Center during the 2015- 2016 academic year to 2016-2017.

Groundwater is the major source of water by inhabitants of Zanzibar communities. In this study, twenty-one water sources from three districts of Urban West Region of Unguja Island were studied in May to July 2019. Insitu measurements for temperature, pH, Dissolved Oxygen (DO) and Electrical Conductivity (EC) in groundwater sources were taken by Professional Digital Sampling System (ProDSS). Data analysis revealed that parameters undergo dynamics (spatial and temporal). During the wet period, the ranges of pH, DO and EC were: (4.98 – 7.50), (3.51 – 7.51 mg/L), and (156.2 – 2047.6 µS/cm) respectively. During dry period the ranges were: (5.14 – 7.41), (2.71 – 7.20 mg/L), and (223.1 – 1936.8 µS/cm) respectively. temperature and EC had positive relationship. Nevertheless, small change in groundwater temperature led a remarkable change in DO. Strong correlation existed between EC and salinity (R2 = 0.999). Also, a strong correlation existed between EC (dry period) and EC (wet period) with R2 = 0.896. During wet period, the mean values recorded for all studied parameters were: 27.87° C, 6.92, 782.85 µS/cm, and 5.44 mg/L for temperature, pH, EC, and DO, respectively. While, during dry period the values were: 27.83° C, 6.97, 743.80 µS/cm, and 5.12 mg/L for temperature, pH, EC, and DO, respectively. Remarkably, during wet period, pH was 4.98 (27.17° C - 28.88° C), while in dry period pH was 5.14 (26.74 - 28.83° C). The present study revealed that even slight change in temperature could cause a remarkable effect on other groundwater parameters specifically dissolved oxygen. If water DO is under pressure it might affect other water quality parameter significantly.
