THE REVOLUTION IN AMERICAN PUBLIC HEALTH POLICY: PETROLEUM-BASED DYES AND THE CHRONIC DISEASE EPIDEMIC

Background: The American food regulatory landscape has historically been influenced by industry interests, resulting in the widespread use of petroleum-derived synthetic food dyes banned in European countries. Chronic disease rates in American children have increased from 3% in the 1960s to approximately 60% currently, with annual healthcare costs reaching $1 trillion. The appointment of Robert F. Kennedy Jr. as Secretary of Health and Human Services marks a paradigmatic shift toward transparency and industry accountability in food safety regulation. Aim: This forum analysis examines Kennedy Jr.'s revolutionary approach to food safety regulation, particularly his confrontational stance against petroleum-based food additives exemplified by his statement, "if they want to eat petroleum, they should add it themselves at home" and evaluates the broader implications for American public health policy and global regulatory standards. Methods: Critical analysis of Kennedy Jr.'s public policy statements, examination of epidemiological data trends, and evaluation of proposed regulatory frameworks through content analysis of official speeches and policy declarations from the Department of Health and Human Services. Results: Kennedy Jr.'s administration targets the systematic elimination of synthetic food dyes through industry partnerships, scientific transparency initiatives, and restoration of rigorous research standards. His confrontational rhetorical approach, compared to Mike Tyson's boxing style, has generated unprecedented industry cooperation with food companies "calling almost daily" seeking compliance guidance. The strategy combines voluntary industry agreements with open-source information databases and enhanced FOIA access. Discussion: This confrontational rhetoric represents unprecedented directness in health policy communication, challenging decades of established regulatory practices. The approach prioritizes scientific transparency over diplomatic language, generating both media attention and voluntary industry engagement that traditional regulatory pressure failed to achieve. Conclusions: Kennedy Jr.'s revolutionary stance may establish new global standards for food additive oversight, prioritizing public health over commercial interests through evidence-based policymaking and industry accountability measures. This paradigm shift from reactive to preventive regulatory models could influence international food safety governance and restore American leadership in global health policy.

DENSE CLUSTERS OF RAW SEWAGE LOCATIONS ON MINNA NEIGHBOURHOOD GIS MAPS ARE POINTERS TO VERITABLE URBAN DECAY AND MOSQUITO-BREEDING GROUNDS

Background: The lack of comprehensive baseline data on raw sewage pollution in Minna, Nigeria's Niger State capital, represents a significant gap in public health information. This deficiency necessitates a systematic study to establish a database documenting sewage pollution patterns in Minna's urban environment. Aim: To employ georeferencing tools and descriptive observations for identifying and mapping potential mosquito breeding sites related to sewage discharge within Minna's built-up areas and to develop an interactive Geographic Information System (GIS) map as an environmental audit tool for public health officials. Methods: The study area was divided into five sectors: Greater Bosso, Minna Central, Greater Maitumbi, Tunga, and Greater Chanchaga. Following initial site familiarization and GIS equipment testing, systematic surveys were conducted. Field teams documented locations of household sewage discharge points, collecting geographic coordinates, temporal data (date, time, weather conditions), and site characteristics. Each identified location was photographed and recorded in standardized data sheets, including household information where available. Results: Using ArcGIS®10.8 software, comprehensive sewage pollution layers were created for each sector by integrating collected field data with Minna's township built-up and settlement shapefiles. The mapping revealed distinct pollution patterns and clusters across different neighborhoods. Discussion: Analysis of the spatial distribution showed a clear correlation between socioeconomic status and sewage management practices, with higher concentrations of improper sewage discharge in low-income areas. Conclusions: This database serves as a valuable resource for public health interventions targeting mosquito breeding grounds. Regular monitoring through periodic sewage pollution audits and expanded geographical coverage is recommended for improved urban health management.

THERMAL AND ECONOMIC ANALYSIS OF LIME PRODUCTION

The ore beneficiation process uses little technology, but mining companies have high economic performance. As an energy source, firewood plays a fundamental role due to its simple storage, low cost, great availability of forests, and lack of processing. Thus, the present work aims to analyze the consumption of firewood as fuel and possible improvements in the process for the production of lime in terms of harnessing raw materials and costs. Calcium oxide is obtained from the thermal decomposition of calcium and magnesium carbonates obtained from dolomitic deposits of limestone (CaCO3 : CaMgCO3). After CaO extraction, it is subjected to a calcination process, removing carbon dioxide (CO2) in ovens that work at temperatures between 900 and 1200°C. The source of energy applied to the calcination furnaces in the analyzed area is wood. The wood has a calorific value between 2,250 and 2,700 Kcal/Kg, but the moisture content responsible for the thermal variation must be considered. The firewood burning process was carried out in a ravine type oven where the temperature at which operators are exposed to heat was evaluated. The results indicated that the cooking time dropped by 20% as the amount of wood is fed into the oven. This increase represents a significant gain in lime production, thus leading to a higher profit for the company.

CLINICAL AND LABORATORY TESTING OF A NEW MODIFICATION OF TWO-LAYER "SILEP" DENTURES USED IN PROSTHETIC DENTISTRY

Dentistry is a part of medicine, where various polymer materials were used for the first time. Many factors forced researchers to find more stable, versatile, and hygienic materials for the manufacture of dental products. It is important to note that the search for the ideal polymer dental material is still ongoing. This is because modern polymers, in some cases, do not meet the specified requirements for chemical, physical, strength, and elasticproperties. Based on the data on the method of creating and using silicone material for the base of the removable prosthesis "Gossil", an improved silicone material for two-layer dentures "Silep" was developed, as well as a special primer for better connection of the lining with the rigid acrylic base of the prosthesis. To evaluate the most suitable compound, materials were tested for several parameters, such as tensile strength, elongation, and shore hardness. In addition to selecting a suitable material for modification, the selection and testing of an adhesive that allows the chemical bonding of the acrylate surface to the siloxane surface were carried out.
