Various measures were recommended or imposed by the governments to control spread of COVID-19. Travel behaviors are significantly influenced due such measures. However, people have various travel needs ranging from grocery shopping work. This study examines changes that occurred in behavior COVID-19 pandemic. Data collected through an online questionnaire survey included questions on trip purpose, mode choice, distance traveled, and frequency trips before during 1203 responses countries...

The outbreak of infectious diseases affects people’s lifestyles significantly, as they undertake fewer outdoor activities a protective measure and to follow government orders restricted movements. This paper reviewed the scientific literature related transport gain insights into managing such circumstances. outcomes indicate that sector has two-fold role during diseases: controlling spread infection assessing impact reduced on sector. It was found local international travel restrictions, if...

This study evaluates effectiveness of anterolateral thigh free flap for reconstructing these complex defects. The aim was assess distal foot. Methods: prospective observational conducted department plastic surgery at Ibn Sina Medical College Hospital, Bangladesh, from July 2022 December 2023, involving 30 patients with Participants provided informed consent, data...

Household energy consumption (HEC) is one of the major contributors to global emissions, making it a critical area for addressing sustainability challenges. The impact personality traits on human behaviour significant in shaping HEC patterns, and therefore, have important implications policies. This study aims investigate role biologically predicted big-two (i.e., stability plasticity), higher order solution five-factor orthogonal traits, HEC. To that end, structural equation model developed...

It is well known that rigid dipolar solutes (in smaller quantity) dispersed in a nonpolar glassy matrix exhibit sub-T(g) (or beta(s)) relaxation due to the solute often designated as Johari-Goldstein (JG) relaxation, which intermolecular nature. In this article, we report results of our study such process wide variety different systems using dielectric spectroscopy over frequency range 20-10(6) Hz down temperature 77 K. The T(g) these solutions are determined differential scanning...

Understanding the psychological factors that influence people's behavior in using sustainable modes of transportation, e.g., public transport, is crucial for promoting environmentally friendly and mitigating climate change. This study examines impact big-two personality traits (stability plasticity) on households' auto transport consumption (ATC) (PTC), their mediating role relationship between socioeconomic (e.g., age, income, education, marital status) consumptions (i.e., ATC PTC). A...

This research proposes an IoT based ideal fish farm that will be low in cost and high production level. A WEMOS D1 microcontroller is engaged determining various essential attributes of the water like pH, oil layer, level, temperature, behaviour to recognize their hungry level have a great effect on fast growth fish. Through our developed mobile app user-friendly web interface end user notified this information. The ESP8266 wifi module built through which system transmits data app. In case...

Purpose The coastal zone of Bangladesh that is in the front line battle against climate change faced over 200 natural disasters past 40 years, and most were cyclones. inevitable cyclone shelter (CS), backbone disaster management (DM), provides short-term safety for victims Bangladesh. This study aims to explore community-based limitations sustainable development features CSs including gender issues. Design/methodology/approach A questionnaire survey was carried out among 230 community people...

Some hexa-substituted benzenes are known to exhibit molecular rotation in their crystalline phase, but this phenomenon is not very well understood. In context, we have critically examined two materials, namely pentachloronitrobenzene and 2,3,4,5,6-pentabromotoluene over a wide range of temperatures, using dielectric spectroscopy differential scanning calorimetry (DSC) ascertain the nature above said relaxation. A relaxation process found which slightly non-Arrhenius its temperature...

We have critically examined the relaxation that is known to occur in crystalline phase of pentachloronitrobenzene (PCNB) and 2,3,4,5,6-pentabromotoluene using dielectric spectroscopy differential scanning calorimetry (DSC). Within resolution our experimental setup, a process similar primary (or alpha-) found. A slight deviation from Arrhenius behavior noticed only vicinity glass transition temperature (T(g)). This small steplike change found DSC scans at T(g) indicates "fragility" these...

During a massive flood or earthquake, the roads are mainly damaged due to looseness of subgrades. In recent times for any new constructions and embankments subgrades constructed with sand filling. It is difficult achieve desired degree compaction beyond certain limit. That’s why bases (subgrades) become loose. This study aims overcome situation by increasing shear strength properties this paper, an intensive laboratory investigation fines sands investigated series proctor test direct test....

The quality of the black topped pavement is based on bituminous materials. To increase strength properties and bitumen several techniques are applied today throughout world. areas within which pavements constructed may be harmful to pavements. Salt one agents mixtures. In coastal belt Bangladesh, sometimes submerged under water for long time. So come in contact with saline salt (Sodium Chloride). Hence Stripping a dominative cause destruction Seawater contains nearly three percent (3%)...

Polyethylene and polyvinyl chloride have been being used as a modifier of bitumen (asphalt cement), whereas application waste polyethylene (WPE) (WPVC) are quite introductory in the field bituminous pavement. This research studied effects soaking periods on compressive strength compacted modified mixes with WPE WPVC. 11% 8% WPVC, optimum contents, were utilised modifying bitumen, which was found from an investigation Marshall properties. Index retained (IRS) Mix-I, Mix-II, Mix-III satisfied...

Global climate change is growing threat to lives and livelihoods on earth where the developing countries are highly exposed climatic variations. Due a unique geographical location Bangladesh one of worst affected by induced hazards. Coastal region country experiences numerous adverse pressures resulting from these natural phenomenon. Long term changes in parameters such as temperature, rainfall, humidity creates extra pressure impact. Agriculture coastal area most vulnerable sectors The...

This study was conducted to produce a salinity tolerant Nile tilapia, Oreochromis niloticus through genetically modified breeding by introducing fragmented purified DNA isolated from Artemia, Artemia salina into the gonads.Two groups of adult fish (16 females and 8 males) were chosen be injected with foreign their gonads using hypodermic needle two different concentrations (10 μg 5 /0.1 ml/fish), besides control group (4 males females) carried out.Post-hatching fry which produced each...

The invention of the Semantic Web and related technologies is fostering a computing paradigm that entails shift from databases to Knowledge Bases (KBs). There core ontology plays main role in enabling reasoning power can make implicit facts explicit; order produce better results for users. In addition, KB-based systems provide mechanisms manage information semantics thereof, semantically interoperable as such exchange share data between them. overcome interoperability issues exploit benefits...

In this paper we deal a classical problem, degree restricted spanning trees for series-parallel graph. Our general goal is to prove the NP-completeness of To define it, let G be connected Let X vertex subset and f mapping from set natural numbers such that f(x)/spl ges/2 all x/spl isin/X. A tree T les/degT(x) isin/X where degT(x) denotes x in T. Here, tree. Many combinatorial problems on graphs are NP-complete, but when graphs, many can solved polynomial time. On other hand, very few known...
