    Opis:
    The Oxfordian ammonite group Passendorferiinae (known as "Mediterranean perisphinctids") forms a group of perisphinctids characterized by strongly evolute serpenticone coiling and subcircular to subquadrate whorl section, and forms a lateral divergent branch of the main stem Perisphinctidae. They originated probably from Late Callovian Grossouvriinae (Alligaticeras) and spread mainly in the Mediterranean (Tethyan) Province along the southern margin of Tethys, occasionally reaching the outer areas of epicontinental platforms. Their particular morphological features make them somewhat homoeomorphic with Tethyan Kimmeridgian Nebrodites. The phyletic link might be represented by the genus Geyssantia Meléndez, known from the Late Oxfordian Planula Chronozone. Separate biogeographic distribution in relation to the Perisphinctinae might reflect a progressive differentiation of western Tethyan faunas at the Callovian-Oxfordian boundary and at the onset of the Middle Oxfordian Transversarium Chronozone. Their rapid evolution gives them a biostratigraphic value similar to that of the Perisphinctinae. At the turn of the Middle-Late Oxfordian they gave rise to early Ataxioceratinae (Orthosphinctes), which replaced the Perisphinctinae in epicontinental areas, and colonised the marginal epicontinental blocks of northern Tethys. The taxonomy of this group is based upon the recognition of sexual dimorphism, using a single generic and specific name for both (M) and (m), and hence rejecting the use of former subgeneric ames for both dimorphs. A new species within this line: Passendorferia nodicostata sp. nov. from the Plicatilis Biozone (Paturattensis Subbiozone) is defined and described for the first time.

    Opis:
    Optimizing codons of gene of interest has offered a value-added way to increase heterologous expression of proteins. Different algorithms have been designed to achieve this purpose. These algorithms make use of parameters such as codon Adaptation index (CAI), codon context (CC), percentage guanine-cytosine (GC) content and RNA instability for predicting optimal codons responsible for increased protein expression. Lipase 3646 is an enzyme with great potential for industrial applications. This enzymes has been described to possess thermostable properties with relative stability in high alkaline pH and at different concentrations of organic solvents and inhibitors. This research therefore used JCat, Codon optimization online (COOL), presyndocon and ExpOptimizer algorithms to predict expression level of lipase 3646 enzyme in silico by optimizing its gene coding sequence. The results showed that there were variations in the CAI generated by the algorithms for the same 3646 DNA sequence which suggests that each algorithm is specific for its own generated CAI. COOL algorithm prediction based on other parameters showed good results for potential expression of the lipase. Thus, we recommend COOL algorithm for codon optimization of the lipase 3646 gene for industrial applications.

    Opis:
    Precipitation is a component of the hydrological cycle, knowing its spatial distribution is vital for the management of hydrographic basins, the territory and the development of fundamental activities for society. That is why the present study shows the spatial variability of rainfall in Cartagena de Indias city with a network of rain gauges, made up of nine pieces of equipment, separated from each other by 0.9-27 km. After a year of recording (2019), using historical series of data, it was found that the maximum rainfall occurs in the trimester between September and November, with interpolated maps made by the Ordinary Kriging (OK) method it was found that the maximum rainfall is focused on the north, centre and west of the territory, instead, the maximum intensities are presented in the centre and west, the minimums for both variables are presented to the east and south. The 70 and 90% of the rain events have a duration of less than 30 min and 1 h, respectively. Three-parameter exponential function was fitted to the paired correlation distances, and presented correlations lower than 0.8, 0.5 and 0.2 from distances of 1, 3 and 7 km, respectively, in 30 min rain integration. It was also found that with a pluviometric network conformed by at least six pieces of equipment and separated by a 5 km distance from each other in the urban area, a correlation of 0.5 and compliance with the WMO recommendations would be obtained.

    Opis:
    Personalised medicine (PM) represents a paradigm shift away from the ‘one size fits all’ approach to the treatment and care of patients with a particular condition, to one which uses emergent technologies such as diagnostic tests, functional genomic technologies, and molecular pathway profiling to better manage patients’ health and employ target therapies. The current challenge for national and regional authorities is to facilitate the shift from a reactive healthcare system based on episodic and acute care models to a personalized health (PH) system that uses preventive and predictive measures, where at-risk individuals are stratified to intervene before the onset of symptoms or risk is predicted using cutting-edge technologies before symptoms appear. While PH is paving the way toward better and more efficient patient care, it still lacks the cooperation and coordination needed to organise the fragmented field, which is a severe drawback to its development and to the placement of effective financial investments. For this reason, it is crucial to direct major efforts towards coordinating and aligning relevant stakeholders across Europe and beyond, creating a participatory approach, building trust, enabling a multi-stakeholder process, and channeling investments towards PH. Thus, Regions4PerMed aims to coordinate regional policies and innovation programmes in PM and PH to accelerate the deployment of PH for patients.

    Opis:
    Ham Cliff near Redcliff Point, Weymouth, Dorset (SW England) exposes one of Europe's most complete Callovian-Oxfordian boundary sequences and has consequently been identified as a potential candidate GSSP for the base of the Oxfordian Stage. The boundary sequence lies within the thick mudrock facies of the Oxford Clay Formation and is abundantly fossiliferous, cardioceratid ammonites in particular being conspicuous. By convention, the stage boundary is drawn at the first occurrence of the genus Cardioceras here represented by C. redcliffense Page, Melendez and Wright at the base of the Scarburgense Subchronozone of the Mariae Chronozone. Associated Perisphinctoidea (including Peltoceras, Alligaticeras and Euaspidoceras) provide additional biostratigraphical information. Other macrofossil groups show less discernible changes, although frequent belemnites (Hibolithes) provide new highresolution carbon and strontium isotope data which are consistent with global curves and continuous sedimentation across the boundary interval. Magnetostratigraphic information is also available. Foraminiferal assemblages are dominated by epistominids but include a flood of early planktonic forms, including ?Globuligerina oxfordiana (Grigelis) immediately above the boundary. Well-preserved nannofloras are dominated by Watznaueria with conspicuous Zeugrhabdotus, podorhabdids and Stephanolithion indicating the NJ14 Biozone. Ostracoda and holothurian spicules are also recorded. These results are synthesised to provide a multidisciplinary, integrated review of the suitability of Redcliff Point for the definition of an Oxfordian GSSP. Correlations with the French candidate site in Haute-Provence are discussed and proposals made for formally establishing a GSSP for the base of the Oxfordian Stage in Europe.

    Opis:
    The overwhelming burden that bisphenol A (BPA) has caused humanity demands clarity as the global society agitates for a safer food packaging component. BPA is a structural component used in hardening of plastics and lining of various food and beverage containers to protect food from contamination and extend shelf life. The study review several literatures on BPA exposures, BPA toxicokinetics, BPA pharmacokinetics, epidemiology and ecological impacts of BPA. Our findings posits that even though BPA does not have a long span per se, its influence and accumulation in human body has a negative long term effect which could lead to several dangerous health implications such as cancer, obesity and fertility problems. These findings challenge the long-standing scientific and legal presumption of BPA's safety and recommends possible safety measures that can be taken in order to reduce exposure to BPA and few of such actions includes; public awareness about BPA and its presence in our daily consumption, negative effects of BPA to the environment and to the human body and finally, thorough investigation of the presence and threshold limit of BPA in plastics and canned foods.

    Despite being an underreported topic in the news media, gender-based violence (GBV) undermines the health, dignity, security and autonomy of its victims. Research has studied many of the factors that generate or maintain this kind of violence. However, the influence of the media is still uncertain. This paper used Big Data techniques to explore how GBV is depicted and reported in digital news media. By feeding neural networks with news, the topic information associated with each article can be recovered. Our findings show a relationship between GBV news and public awareness, the effect of well-known GBV cases, and the intrinsic thematic relationship of GBV news with justice themes.

    Opis:
    Rapid urban growth and expansion pose daunting challenges in urban areas of the developing world. These challenges include the provision and equitable distribution of sustainable public water supply facilities. This study therefore aimed at assessing the extent of spatial inequality in the distribution of water facilities provision among major segments in Lapai urban centre, Nigeria to aid policy formulation and framework in achieving sustainable water supply. This study utilizes the Gini coefficient composite statistical tool to examine the distribution inequality of three main sources of public water facilities in the study area, which includes; hand pump boreholes, motorised boreholes, and wells. The study area is divided into four quadrants (quadrants A, B, C, and D). It was found out that 17.31%, 21.15%, and 37.50% Gini coefficients were recorded for hand pump boreholes, motorised boreholes, and well facilities. This indicates that there is inequality in the distribution of public water supply facilities among the four quadrants in the study area. It was therefore recommended that both the public and private sectors should provide public water facilities equitably to achieve Sustainable Development Goals (SDGs).
    Szybki rozwój i ekspansja miast stanowią trudne wyzwania w obszarach miejskich rozwijającego się świata. Wyzwania te obejmują zapewnienie i sprawiedliwą dystrybucję publicznych urządzeń wodociągowych. W związku z tym badania miały na celu ocenę zakresu przestrzennych nierównomierności dystrybucji wody w głównych obszarach centrum miejskiego Lapai w Nigerii w celu wsparcia formułowania polityki i ram w osiąganiu zrównoważonego zaopatrzenia w wodę. W niniejszym opracowaniu wykorzystano złożone narzędzie statystyczne ze współczynnikiem Giniego w celu zbadania nierównomierności dystrybucji trzech głównych publicznych obiektów wodociągowych na badanym obszarze, w tym: odwierty z pompą ręczną, odwierty z napędem silnikowym i studnie. Badany obszar podzielony jest na cztery ćwiartki (ćwiartki A, B, C i D). Stwierdzono, że współczynniki Giniego 17,31%, 21,15% i 37,50% odnotowano dla odwiertów z pompą ręczną, odwiertów silnikowych i obiektów studniowych. Wskazuje to na nierównomierność w rozmieszczeniu publicznych urządzeń wodociągowych w czterech ćwiartkach badanego obszaru. W związku z tym zalecono, aby sektor publiczny i prywatny zapewnił sprawiedliwe dostęp do publicznych obiektów wodociągowych tak, aby osiągnąć cel zrównoważonego rozwoju (SDG).

    Opis:
    Artificial Intelligence (AI) can be defined as the application of science and engineering with the intent of intelligent machine composition. It involves using tool based on intelligent behavior of humans in solving complex issues, designed in a way to make computers execute tasks that were earlier thought of human intelligence involvement. In comparison to other computational automations, AI facilitates and enables time reduction based on personnel needs and most importantly, the operational expenses. Artificial Intelligence (AI) is an area of great interest and significance in petroleum exploration and production. Over the years, it has made an impact in the industry, and the application has continued to grow within the oil and gas industry. The application in E & P industry has more than 16 years of history with first application dated 1989, for well log interpretation; drill bit diagnosis using neural networks and intelligent reservoir simulator interface. It has been propounded in solving many problems in the oil and gas industry which includes, seismic pattern recognition, reservoir characterisation, permeability and porosity prediction, prediction of PVT properties, drill bits diagnosis, estimating pressure drop in pipes and wells, optimization of well production, well performance, portfolio management and general decision making operations and many more. This paper reviews and analyzes the successful application of artificial intelligence techniques as related to one of the major aspects of the oil and gas industry, drilling capturing the level of application and trend in the industry. A summary of various papers and reports associated with artificial intelligence applications and it limitations will be highlighted. This analysis is expected to contribute to further development of this technique and also determine the neglected areas in the field.
