The advancement of Assisted Reproductive Technologies (ARTs) has greatly revolutionised reproductive rights, providing new opportunities for couples as well as individuals facing infertility. This paper explores Reproductive Rights and the constantly developing concept and usage of ARTs. It also examines how it has facilitated the realization of reproductive rights while also presenting novel ethical, legal, and socio-economic challenges. This work traces the historical development of reproductive rights both internationally and within Nigeria, while providing insights to the resultant perception on the use of ARTs. Using a doctrinal research methodology, this paper critically examines issues like the lack of legislation and guidelines, rights of children as well as some legal and ethical issues that arise as a result of the use of ARTs in Nigeria while also aiming to protect the reproductive rights of citizens. Findings reveal that the absence of comprehensive legislation creates significant legal uncertainty for stakeholders, including intended parents, donors, and medical practitioners. Additionally, the high cost of ARTs restricts access to only the wealthy, thereby undermining the fundamental right to reproduction. In conclusion, this paper emphasizes the urgent need for legislative intervention to regulate ARTs in Nigeria. It recommends the enactment of clear legal frameworks that safeguard reproductive rights, ensure equitable access, and address ethical concerns. Additionally, increased advocacy and public education are necessary to promote awareness and reduce the socio-cultural stigma associated with ARTs

Introduction: For the first few years after menarche, irregular and longer cycles are common. Early recognition and appropriate management of menstrual problems can significantly reduce the adverse impact on academic performance, self-esteem, and social participation. Present study was undertaken to study about various Gynecological problems especially menstrual complaints and to analyze various causes of the menstrual abnormalities Objective: To study about various gynecological problems especially menstrual complaints among the school going adolescent girls in the age group of 11-18 years and to analyze various causes of the menstrual abnormalities in them. Materials and Methods: It was a prospective observational study of adolescent girls attending the Gynecology OPD at a tertiary hospital, for the period of one year. Data were collected by using proforma after obtaining patients’ consent. Results: Total 80 adolescent girls came in Gynecology OPD at our hospital. The maximum incidence of complaints was seen at the age group of 16 years. The mean age of menarche in this study was 13.3 years. Menstrual disorders were seen among 56.25%. Among various menstrual complaints, Oligomenorrhoea (45.0%) was the common menstrual problem, followed by Dysmenorrhoea (29.50%), Menorrhagia (13.11%), Poly menorrhea (8.19%), Hypomenorrhea (3.27%) and Primary amenorrhea (1.63%). Conclusion: Adolescent girls experience a variety of gynecological complaints, with menstrual disorders being the most common. Menstrual irregularities are typically expected within the first 1–2 years following menarche; however, if they persist, evaluation for conditions such as polycystic ovary syndrome (PCOS) and hypothyroidism is recommended. Early diagnosis of PCOS is essential to prevent future reproductive and metabolic complications.

Исследовано влияние на кинетику полимеризации и сополимеризации тетрафторэтилена (ТФЭ) с гексафторпропиленом (ГФП) температуры, концентрации низкотемпературного инициатора – диизопропилпероксидикарбоната, продолжительности реакции, соотношения мономеров в исходной смеси, а также наличие в системе органических жидкостей. Установлено, что с увеличением температуры, концентрации инициатора и продолжительности реакции выход политетрафторэтилена (ПТФЭ) и сополимеров ТФЭ с ГФП повышаются. Показано, что ПТФЭ и сополимеры ТФЭ с ГФП являются стойкими к действию таких органических жидкостей, как диметилформамид, диметилсульфоксид и др. при температуре их кипения. На основе рентгенографических исследований установлено, что с увеличением содержания ГФП степень кристалличности сополимеров ТФЭ с ГФП уменьшается. Следует отметить, что введение ГФП звеньев в состав сополимера приводит к незначительному снижению его термостойкости.

Deliverable 4.3 (D4.3), is part of Task 4.3 “Collection of future climate projections at the demo site locations” (Lead: UNIPR/ Participants: UFZ, RSS, UPV, IDRICA, TdV, TUC, UNISS, UNINA, RSCN, LPM, AGRI, ESIM, BU), (M6-M24). Titled “Short- and long-term climate projections at each demo site”, D4.3 presents climate datasets obtained through the methodologies outlined in Milestone 4.3 (M4.3, Secci et al., 2025). It provides a comprehensive analysis of climate simulations across different time horizons (near-, short-, and long-term), with a focus on temperature and precipitation, key variables for assessing future water availability and water resource management. The deliverable reports results at the Mediterranean scale (for long-term projections), as well as for the individual demo sites. Additionally, D4.3 presents the archive of the climate data produced for OurMED, accompanied by a detailed explanation of data formats, ensuring that Consortium members can effectively utilize these datasets for future planning and the development of adaptation strategies.

La recherche d'images (RIM1) constitue une partie importante de la recherche d'information sur Internet. Malgré leur succès, les systèmes de RIM ont une série de limitations dont une partie découlent de leur insensibilité à la sémantique. Nous analysons ici l'introduction de structures sémantiques à grande échelle dans la recherche d'images sur Internet. Plus précisément, nous présentons quelques ressources utilisables, ainsi qu'un modèle d'agrégation de l'accès aux images par le texte et des techniques de traitement d'images. Enfin, nous illustrons nos propos avec quelques applications déjà implémentées ou en cours de développement. Une attention particulière est accordée au couplage des solutions proposées avec des usages existants ou potentiels. Les principaux avantages et difficultés liés à l'introduction d'une couche sémantique dans les systèmes de recherche d'images sont systématiquement mis en avant.
