Raw wastewater heat recovery study
No full textIki šiol daugiau nei du trečdalius pasaulinės energijos poreikio patenkina neatsinaujinanti energija, gaunama
iš gamtos išteklių. Tyrimai rodo, kad pasaulinio ir regioninio energetinio saugumo rizika didėja dėl gamtos išteklių
išeikvojimo. Tuo pačiu metu pastatų modernizavimas atlieka pagrindinį vaidmenį mažinant energijos naudojimą ir poveikį
aplinkai. Tyrime analizuojamas šiluminės energijos išgavimo iš nuotekų potencialas. Aptariami klausimai, susiję
su aplinkosaugos, ekonominiais ir praktiniais suvaržymais, kaip realiai galima atgauti šią energiją, galimybės sumažinti
anglies pėdsaką. Šiame straipsnyje nagrinėjama aprūpinimo energija alternatyva, kiek šilumos būtų galima atgauti iš
nuotekų ir ar ši šiluma gali būti veiksmingai panaudota.More than two-thirds of the world’s energy needs
are met by non-renewable energy from natural resources. Research
shows that the risk to global and regional energy security
is increasing due to the depletion of natural resources.
At the same time, building modernization plays a key role in
reducing energy consumption and environmental impact. The
study analyses the potential of thermal energy recovery from
wastewater. Issues related to environmental, economic and
practical constraints, how this energy can be realistically recovered,
and the possibilities for reducing the carbon footprint
are discussed. This article examines the alternative energy
supply, how much heat could be recovered from wastewater
and whether this heat can be effectively used.Baltijos Amerikos klinikos administracijaTaip / Ye

No full textPrieinamos ir įtraukios aplinkos konferencija „LIETUVA VISIEMS 2025“ – jau antroji. Pirmoji 2023-aisiais metais taip pat vyko LR Seimo rūmuose. Nagrinėjamų klausimų ratas išlieka platus: nuo miesto erdvių iki pastatų, informacijos ir bendro įtraukties suvokimo. Giliau pažvelgus į mūsų pažangos kelią ir iškylančias problemas suprantame, kad rezultatą pasieksime greičiau, jei dirbsime drauge: vystytojai, naudotojai, projektų rengėjai architektai, urbanistai, kraštovaizdžio architektai, inžinieriai, teisinės aplinkos kūrėjai ir jos prižiūrėtojai. Dirbti drauge – tai dalintis teorinių tyrimų, praktinio darbo ir reglamentų taikymo patirtimi; išlipti iš profesinio apkaso ir girdėti vieniems kitus; tai siekis žvelgti į šių dienų poreikius matant perspektyvą ir ateityje galinčius kilti socialinius, ekonominius, aplinkos ar mūsų miestų tvarkymo estetinės kokybės klausimus. Taip pat prasminga išlaikyti ir didinti aplinkos naudotojų ir suinteresuotų asmenų grupių įtrauktį į tvarios ir prieinamos aplinkos kūrimą. Sieksime, kad ši tradiciniu mokslo ir praktikos forumu tampanti konferencija išlaikytų platų tarpdalykinį profilį, aštrų žvilgsnį į realaus gyvenimo problemas lokaliu ir tarptautiniu mastu, o siūlymus ir rekomendacijas grįstus mokslo tyrimų rezultatais.The conference on accessible and inclusive environments, “LITHUANIA FOR ALL 2025,” is now in its second year. The first conference was also held at the Parliament of the Republic of Lithuania in 2023. The range of issues discussed remains broad: from urban spaces to buildings, information, and the general perception of inclusion. Looking deeper into our path of progress and the problems that arise, we understand that we will achieve results faster if we work together: developers, users, project designers, architects, urban planners, landscape architects, engineers, legal environment creators, and supervisors
The effectiveness of intelligent transport systems in Lithuania’s road infrastructure
No full textIntelektinės transporto sistemos (ITS) yra esminis modernios kelių infrastruktūros elementas, leidžiantis
didinti eismo saugumą, optimizuoti transporto srautus ir užtikrinti kelių dangos ilgaamžiškumą. Atlikta ITS analizė
Lietuvos keliuose atskleidė, kad esamas ITS diegimas Lietuvoje yra fragmentuotas, o tai riboja eismo valdymo efektyvumą
ir didina kelio dangos nusidėvėjimo tempą. Šiame straipsnyje aptariamas ITS diegimo netolygumas ir jų tarpusavio
sąveikos stoka, kuri riboja technologijų potencialą efektyviai valdyti eismo srautus ir užtikrinti infrastruktūros
ilgaamžiškumą. Remiantis tarptautine praktika, siūlomas ITS efektyvumo vertinimo algoritmas, kuris leistų objektyviai
įvertinti ITS sprendimų naudą ir jų taikymo efektyvumą.Intelligent Transport Systems (ITS) are an essential
element of modern road infrastructure, allowing us to improve
traffic safety, optimise traffic flows and ensure the longevity
of pavement. The analysis of ITS on Lithuanian roads
has shown that the existing ITS deployment in Lithuania is
fragmented, which limits the efficiency of traffic management
and increases the rate of pavement deterioration. This paper
discusses the unevenness of ITS deployment and the lack of
interaction between them, which limits the potential of the
technologies to effectively manage traffic flows and ensure the
longevity of infrastructure. Based on international practice, an
algorithm for assessing the effectiveness of ITS is proposed,
which would allow an objective assessment of the benefits of
ITS solutions and the efficiency of their application.Taip / Ye

yra pralaidumo vandeniui koeficiento k10 nustatymas. Šiuo metu šis bandymas atliekamas laboratorijoje bandiniui paimtam
objekte. Paprastai šis bandymas trunka apie 1–3 darbo dienas, priklausomai nuo duomenų apimties, reikalingos
tinkamumo bandymui atlikti, kiti kontrolės bandymai trunka trumpiau. Siekiant paspartinti darbų priėmimą, sluoksnio
pralaidumas vandeniui lauko sąlygomis gali būti nustatomas vertikaliuoju vamzdiniu infiltrometru. Straipsnyje
nagrinėjamas kelio dangos konstrukcijos pagrindo sluoksnio pralaidumo vandeniui matavimas infiltrometru. Analizuojami
sluoksnio iš nesurištojo mišinio filtracijos koeficiento ir pralaidumo vandeniui koeficiento matavimų, atliktų
skirtinguose objektuose su skirtinga medžiaga, rezultatai. Įvertinta priklausomybė tarp nesurištojo mišinio filtracijos ir
pralaidumo vandeniui koeficientų.This article analyzes the relationship between the
water permeability and filtration coefficient of the unbound
base layer of a road pavement structure. After installing a protective
frost-resistant layer, one of the control tests performed
is the determination of the water permeability coefficient k10.
Currently, this test is performed in the laboratory on a sampled
object. Usually, this test lasts about 1–3 working days, depending
on the volume of data required for the suitability test.
While other control tests last shorter. In order to accelerate
the acceptance of works, the water permeability of the layer
under outdoor conditions can be determined using a vertical
tubular infiltrometer. The article analyzes the measurement of
the water permeability of the base layer of a road pavement
structure using an infiltrometer. The results of measurements
of the filtration coefficient and water permeability coefficient
of a layer from an unbound mixture, carried out in different
objects with different materials, are analyzed. The dependence
between the filtration and water permeability coefficients of
the unbound mixture is evaluated.Taip / Ye
Assessment of chronic fatigue in the work environment – CFS methodology
No full textA toxic or mismanaged work environment, along with a lack of support and self-care opportunities, can
directly contribute to chronic fatigue. It’s important for organizations to recognize these connections and implement
strategies to promote healthier, more sustainable work environments. The paper presents the results of the verification
of the new, original CFS methodology for the assessment of chronic fatigue syndrome. On a research sample of 366
employees working in different work areas, three attributes were extracted using factor analysis: Fatigue at work, Stress
at work, Perfectionism, which explain 50.859% of variance. The basic psychometric parameters of the CFS methodology,
the values of Cronbach’s alpha and the differences in the assessment of factors are also presented. The aim of the
paper was therefore to approach the issue from a theoretical as well as methodological point of view and to point out
the possibilities of assessing its syndromes in its infancy. In order to collect data and information, we opted for a questionnaire
focused on chronic fatigue. The methodology consists of 20 statements related to the assessment and subsequent
detection of symptoms of the assessed disease. The analysis of the data confirmed the existence of statistically
significant differences in the assessment of individual extracted factors of the CFS methodology. If an individual finds
that he or she is affected by chronic fatigue, he or she can start preventive measures in advance.Taip / YesKEGA018PU-4/202
Environmental sustainability and sustainable fashion: between necessity and reality
No full textDarni aplinka ir tvarumas mados industrijoje yra aktualus klausimas šiandienos pasaulio kontekste. Mados
pramonė yra pripažinta viena labiausiai aplinką teršiančių industrijų visame pasaulyje. Jos poveikis aplinkai apima didelę
vandens ir oro taršą, energijos bei cheminių medžiagų suvartojimą ir didelį atliekų kiekį – nuo mikroplastiko iki
neparduotos tekstilės. Dabar tvari mada skelbia naują sąmoningumo erą. Gyvename perteklinio vartojimo amžiuje, ir
tai ypač akivaizdu mados industrijoje. Visas drabužių gamybos procesas taip pat generuoja tekstilės atliekas. Būtinybę
keisti žmonių vartojimo įpročius ir pradėti saugoti planetą akcentuoja ir naujausia CNN klimato ataskaita. Mokslininkai
įspėja apie kritinę situaciją pasaulyje: pirmą kartą žmonijos istorijoje sutrikdytas Didysis vandens apytakos ratas –
sudėtinga sistema, kuria vanduo juda aplink Žemę. Dešimtmečius trukęs destruktyvus žemės naudojimas ir netinkamas
vandens išteklių valdymas lėmė krizę, kurią dar labiau gilina žmogaus veikla. Ši vis auganti ekologinė katastrofa
turės rimtų padarinių ekonomikai, maisto tiekimui ir žmonių sveikatai bei gyvybėms.Environmental sustainability is a critical issue in
the fashion industry today. This industry is recognized as one
of the most polluting sectors globally. The fashion industry
significantly impacts the environment through water and air
pollution, high energy and chemical consumption, and the
production of large amounts of waste, including microplastics
and leftover textiles. Sustainable fashion is now directing in
a new era of awareness. We live in a time of overconsumption,
particularly noticeable in the fashion industry. The entire
clothing production process contributes to textile waste. The
recent CNN climate report (on October 16, 2024) emphasizes
the urgent need to change people’s consumption habits and
take action to protect our planet (Paddison, 2024). Scientists
warn of a catastrophic situation, stating that the global water
cycle is off balance for the first time in human history. The
Great Water Cycle is the complex system through which water
moves around the Earth. Decades of destructive land use
and mismanagement of water resources have created a manmade
crisis. This escalating catastrophe will severely impact
the economy, food production, and human lives.Taip / Ye
Impact of IOT on B2B digital marketing: investigating the mediating role of operational effectiveness
No full textThe emergence of the Internet of Things (IoT) has driven a significant shift in business processes, particularly
in online marketing. This study examines the impact of IoT implementation on marketing performance, emphasizing
the mediating role of operational effectiveness in a business-to-business (B2B) context. Using data from a German
company, the research employs regression analyses based on the Baron and Kenny framework to assess direct and
mediated relationships. The findings reveal that IoT has a significant positive effect on marketing performance. While
operational effectiveness alone does not significantly predict IoT’s impact, it has a strong direct influence on marketing
outcomes. The study confirms a partial mediation effect, with a small yet statistically significant indirect pathway. These
results highlight the important role of operational effectiveness in maximizing the benefits of IoT for marketing success.
This research contributes to the limited literature on IoT’s mediating variables in marketing and offers actionable
insights for optimizing IoT-driven B2B marketing strategies.Taip / Ye
The role of ergonomic work environments in reducing mental and physical strain among office workers: systematic literature review
No full textThe work environment affects office workers’ well-being. Prolonged sitting, poor ergonomics, and job demands
contribute to musculoskeletal issues and stress. Ergonomic solutions, like adjustable desks and micro-breaks,
improve health and productivity. This study aims to analyze the role of ergonomic work environments in reducing
mental and physical strain among office workers, identifying the most effective strategies for improving employee
well-being and productivity. A systematic review of PubMed and Scopus (2000–2024) used keywords: “ergonomics,”
“mental strain,” “physical strain,” and “office workers.” Studies were selected for relevance to workplace ergonomics
and well-being. Poor ergonomics and inactivity increase physical strain, while job pressure heightens stress. Physical
activity, ergonomic workstations, and social support improve well-being and productivity at work among office workers.
The role of technology has been analyzed and proved that it can help reduce cognitive load but may also generate
additional stress if implemented without careful consideration. The efficiency of these interventions has been proved
across diverse sectors and global settings. Future research should examine long-term effects of ergonomics role in office
workers.Taip / YesImpact of ergonomics and psychosocial risks on work performance for office workers in banking sectorLU-BA-ZG-2024/1-0018ESS2024/465-ZG-
