Abstract This research highlights the waste types and their
principal characteristics produced from the main activities in an
investigated livestock farm, especially collected wastewaters from different
zootechnical activity sectors. Six monitoring sectors were selected to
assess the level of polluting load from the discharged effluents. Constant
control of the main imposed quality indicators (pH, COD, BOD, total solids,
ammonia, extractible substances) is obviously required and periodically
reported to water regulatory management authority, as well as the
establishment of viable and efficient directions utilized for the wastes
treatment and recovery on-site (direct possible use). The limiting norms of
the quality indicators controlled in a few sectors (mainly 4 control
sectors) are far exceeded and the trend is to increase the polluting loads,
which requires the adoption of serious local treatment measures and the
continuation of monitoring the quality status of the effluents generated on
the livestock farm. Keywords: environmental protection, wastewater,
livestock farm, quality indicators

Abstract The tourism sector holds a central role in achieving
Sustainable Development Goals (SDGs) as it generates jobs and income and
contributes to economic growth. Factors such as globalization, changes in
transportation, population growth, technological advancements, digital
platforms, and increasing communication channels contribute to its
development. This study aims to explore the convergence between responsible
tourism and the SDGs, focusing on popular tourist destinations. It seeks to
identify successful strategies and new approaches for promoting responsible
tourism, focusing on poverty reduction, environmental protection, cultural
heritage preservation, and inclusion. The paper also presents case studies
from different destinations and offers concrete suggestions for
policymakers, tourism stakeholders, and community members on how to
incorporate fair tourism concepts into their strategies. The findings have
implications for policy actors, stakeholders, and professionals involved in
tourism management and sustainable development. A better understanding of
the economic and environmental dimensions of tourism enables stakeholders to
develop informed strategies to maximize the benefits of tourism while
mitigating its negative impacts on the environment and local communities. Keywords: economic development, environmental conservation, SDGs,
sustainability, tourism impact

Abstract his paper examines the interinstitutional responsibilities
involved in managing interventions on watercourses, highlighting the need
for a unified approach to ensure efficient and sustainable water resource
governance. Watercourses are critical for environmental, economic, and
public safety, but their management often involves multiple institutions
with overlapping duties, leading to inefficiencies and gaps. The report
outlines the roles of key stakeholders, including environmental agencies,
local authorities, and regulatory bodies, and emphasizes the importance of
clear responsibilities and strong collaboration. It advocates for integrated
management systems that streamline decision-making, reduce bureaucracy, and
align interventions with national and EU water policies. The report also
proposes collaborative platforms for sharing data and best practices, and
calls for joint action plans to improve institutional coordination.
Ultimately, it recommends establishing a unified framework to enhance the
effectiveness, transparency, and sustainability of interventions on
watercourses. Keywords: managing watercourse interventions, unified

Abstract The work aimed at producing “one-part” geopolymer composite
material using coal fly ash and granulated blast furnace slag as
alumina-silicate precursors, sodium carbonate as a solid alkali activator,
and sodium lignosulphonate as a water-reducer superplasticizer, constituting
a dry powder mixture, to which water was added later. This preparing way of
the geopolymer is an alternative version to the traditional “two-part”
geopolymer using liquid alkaline activation and is mainly suitable for
in-situ construction applications. The results of the current experiment
showed good thermal insulation properties, the density and heat conductivity
values being quite low as well as quite high levels of compression and
flexural strength, early strength values after only 7 days being high
considering the final mechanical resistance values after 28 days.
Keywords: solid alkali activator, “one-part” geopolymer, fly ash, slag,
sodium carbonate

Abstract Malaria is transmitted to humans through the bite of
infected female Anopheles mosquitoes carrying Plasmodium parasites. In
Cameroon, mosquito control primarily relies on long-lasting
insecticide-treated nets (LLINs), which may cause skin irritation and
respiratory discomfort due to synthetic pyrethroids. This study explores a
potential natural alternative: weft-knitted Sida rhombifolia
fabrics treated with Aloe vera gel. Nine (9) samples were tested, including a
positive control (permethrin-treated net), a negative control (untreated
net), and seven experimental fabrics: untreated Sida rhombifolia
fabric, fabric treated with Aloe vera, the same fabric washed twice,
permethrin-treated Sida fabric, and Aloe vera-treated fabrics stored for 1,
2, and 3 months. Two WHO-standard bioassays were conducted: cone tests
(3-minute exposure) and cylinder tests (15-minute exposure), using wild
Anopheles gambiae populations from Yaoundé. Fabrics treated with Aloe
vera showed promising mortality rates, reaching up to 22% in cone tests and
25% in cylinder tests, comparable to those of permethrin. Efficacy declined
slightly over time, particularly after 3 months of storage or brief contact
exposure. These findings suggest that Aloe vera-treated Sida
rhombifolia textiles could serve as natural, biodegradable alternatives
to LLINs, subject to further optimisation for long-term stability and field
deployment. Keywords:

Abstract This documentary study presents the possibilities of
selective oxidation by sodium or potassium periodate and/or
2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO) of cotton textiles, the reaction
mechanisms, the assessment and the analytical and instrumental determination
of the degree of oxidation of the hydroxyl groups in the C2, C3 and C6
positions of the anhydroglucosidic unit (AGU), with aldehyde/carboxylic
groups. The effects of selective oxidation on the molecular and
morphological structure of cellulose are also briefly presented, since
oxidation depending on the reaction conditions can significantly affect both
the amorphous and crystalline areas of cellulose, at the microfibril level,
which leads to a decrease in mechanical resistance, which is undesirable in
the case of textiles with long-term use or even single-use. Selective
oxidation in this case is a compromise between functionality (expressed by
the content of aldehyde/carboxylic groups) and moderate degradation of the
molecular and morphological structure of cotton cellulose. Keywords:
oxidized cellulose, sodium or potassium periodate, TEMPO, aldehyde and
carboxyl groups, degree of oxidation

Abstract Drinking water quality is essential for maintaining human
health and ecological balance. Therefore, implementing standards and
legislative directives/ordinances is important to protect human health.
Water regulations play a crucial role in the efficient management of water
resources, particularly in clean water and sanitation. This analysis
evaluates the main water quality parameters regulated by national and
European standards and highlights the problems related to the implementation
of water quality standards in Romania. This study presents the main
limitations of the standards related to underestimation of risks associated
with emerging toxic contaminants, the adoption of inadequate limit values
for current public health requirements, inadequate analytical techniques at
international level or protocols, and existing tools for their monitoring.
The conclusions of this analysis in the Romanian context indicate
deficiencies in several synthetic chemicals and biological species. The
implementation of regulations and standards is essential for sustainable
water management, and regional and international partnerships are key
solutions to overcome these obstacles. Keywords: drinking water quality,
monitoring, water policies, EU Directives, water resources management

Abstract This study analyses the fractionation of vegetable oils
using the methods known up to this point and examines the use of these
fractions in various industries. Emphasis was placed on sunflower oil due to
its high-oleic acid content, which has health benefits. As a novel
fractionation method, the work primarily focuses on molecular distillation,
a method that leads to high purities, advantageous for heat-sensitive or
easily degradable substances and has been studied up to pilot scale until
now. Three sunflower oil samples were subjected to experimental and
empirical analysis. The results were compared with available literature data
and process simulators outputs. Keywords: vegetable oils, oil
fractionation, sunflower oil, molecular distillation, methanol
transesterified oil fractionation
