Mugla Province, which has been selected as the study area, is located in the Aegean Extension Region (AER), where seismic motions are widely observed. Moreover, the AER is the most active part of the Eastern Mediterranean Region in terms of seismic activity, and this seismicity has been continuing increasingly. This study aims to determine the seismic hazard of Mugla Province and its surroundings by using the probabilistic seismic hazard method. The earthquake dataset including 19,824 seismic records that were used in the research was obtained from the national and international earthquake catalogs. The data about the active fault zones in the study area were acquired from the General Directorate of Mineral Research and Exploration. The seismic source zones were generated as homogeneous areas as possible taking into account the active fault zones. The earthquakes in seismic source zones were eliminated based on the time and distance frames. The annual recurrence relationships of the source zones were determined using the least-squares method taking into account the earthquakes with a magnitude of 5 or above. The peak acceleration values on the bedrock were calculated using the attenuation relationships of the selected local and global ground motion prediction models. The calculations were performed using the SEISRISK III software package utilizing the homogeneous Poisson Process Model according to the exceedance probability of 10% for 50 years (corresponding to the return period of 475 years). The peak acceleration values on bedrock were found to range between 0.11 and 0.42. The study revealed that the Gokova fault zone (Zone 4) was the most active source in terms of the seismic hazard in the region and that the seismic hazard of the southwestern part of the region was greater compared to other parts.

Industrial activities generate considerable volumes of wastewater containing organic and inorganic contaminants. Adsorption is an efficient method for wastewater treatment due to its ease of operation, convenience, and efficiency. However, finding suitable adsorbent materials that are abundant, cheap, and efficient remains a challenge. Gelatin is considered a promising adsorbent due to its abundant surface of active groups, water solubility, non-toxicity, and biodegradability. Also, gelatin allows the addition of other compounds in the gel network, overcoming some disadvantages such as low mechanical resistance to temperature and humidity. Here we review the production of gelatin-based composites including beads/spheres, hydrogels, aerogels, and films, and their use to remove toxic metals, dyes, nitrate, phosphate, and oily contaminants from aqueous matrices. Considerations Economic, environmental, and real applications aspects are also discussed.

Trichoderma strains have several biotic and abiotic functions important for agriculture. However, their efficiency varies depending on different aspects. In this context, this study aimed to evaluate the agronomic efficiency of a Trichoderma asperelloides-based inoculant (FT10), to verify its ability to promote soybean growth (Glycine max). The experiments were conducted at field level in four distinct edaphoclimatic zones in Brazil. The statistical design used was in randomized blocks, with six treatments and four replications. The treatments applied were: (1) Control;(2) Positive control (Co-Mo Platinum);(3) Standard product (ICB Nutrisolo Trichoderma);(4, 5 and 6) FT10 Inoculant (2, 5 and 10 g ha-1, respectively). The parameters evaluated were: plant stand, number and mass of nodules, shoot and root biomass, mass of one thousand grains and soybean yield. The doses of 5.0 and 10.0 g ha-1 of FT10 contributed to the increase in germination and final plant stand, as well as to the increase of shoot and root biomass. In this study, 5.0 g ha-1 of FT10 presented the highest number and mass of nodules in relation to the control. The gains in these parameters resulted in higher yields that were statistically different from some control trials, with an increase in grain yield between 8.9 and 15.1% compared to the control. Therefore, Trichoderma asperelloides can be used as a soybean growth promoter, and its application via the sowing furrow of 5.0 g ha-1 of FT10 is the most promising treatment.

Urban expansion within Greater Irbid Municipality (GIM) witnessed an extraordinary rise, expanding approximately ninefold between 1967 and 2020. Recent trends revealed a shift in urban growth towards southern and eastern regions. These dynamics carry critical implications for urban planners and environmental managers, urging a comprehensive understanding of the driving factors behind this expansion to anticipate future challenges. Employing logistic regression (LR) and geographically weighted logistic regression (GWLR) analyses using remote sensing data and GIS, spatially variant coefficients for driving factors emerged, illuminating the evolving landscape of urban development drivers within GIM. Yarmouk University historically promoted urban expansion, but recent proximity to Yarmouk University and JUST University, coupled with higher existing building percentages, inhibited further urbanization. The analysis also revealed that elevation and slope had negligible impacts on urban expansion. These findings underline the evolving dynamics of urban development drivers within the study region. The local perspective depicted significant spatial disparities in coefficients, highlighting variations in magnitude and direction. GWLR emerged as a more robust methodology, effectively capturing regional variations and enhancing model reliability. These findings hold immense value for informing current and future urban planning practices in Greater Irbid Municipality. Proactively addressing identified challenges and understanding the intricate dynamics of urban expansion can assist Irbid in shaping a sustainable and resilient future, avoiding potential pitfalls in its urban development endeavors.

One of the most effective, economical, environmentally friendly, and easily applied methods used to combat the overheating of urban areas is properly arranging the urban landscape. In particular, road networks play an important role in the heating of urban areas and occupy the most area among the different types of public spaces. Hence, it is evident that street landscape design methods represent a significant resource for enhancing urban climate change resilience. In this study, the effect of plantation of streets with trees on the local climate was investigated for Istanbul and Antalya in Turkey. In the comparison of these two cities, four pattern types (discrete low-rise, discrete mid-rise, discrete high-rise, compact low/mid-rise) that are common in both were used. The simulations were performed by BPNN method that used the synthetic images obtained by manipulating the original satellite images. By this way, as a result of the simulations, the synthetic surface temperature images of planted streets were obtained. The climatic changes were examined by applying thermal change detection analysis and cooling distance analysis for the streets that were planted with trees. According to these results, street tree plantation leads to a cooling effect that extends up to 50 m in Istanbul and up to 300 m in Antalya varying according to the urban pattern type. When the results were compared between the discrete pattern types, it was found that the cooling effect due to street tree planting in the low-rise was effective up to longer distances than the high-rise pattern types.

With a case of South Korea, this study attempts to analyze how the severity of traffic crashes for which older drivers are at fault is associated with road/environmental/seasonal/weather conditions, driver's attributes, and crash/violation types. It analyzes the ordinal variable of injury severity by specifying conventionally used ordered logit and its statistical alternatives, multinomial logit, generalized ordered logit, partial proportional odds models. Based on the assumptions and fits of the models, this study finds that relative to the poor, but conventional ordered logit model, the best-fit generalized ordered logit model reports more accurate results in terms of the coefficient significance, direction, and magnitude. Among its major findings, although the severity decreases by year (conventional model), it does not apply to the minor injury level (alternative). The higher severity in the picnic season (conventional) is also limited to the level of minor injury or less. The times of the day at which the severity is higher (4-6) and lower (8-21) (conventional) are specific to fatal and serious injuries, respectively (alternative). Several variables have double-edged effects. Single-vehicle crashes do not always result in higher severity. They also reduce it to the lowest report-only level. Likewise, age and alcohol use change the severity to the most severe fatal level as well as to the most minor report-only level. These results are compared with the accumulated findings of crash frequency studies and interpreted in relation to older drivers' high cautiousness and low physical/cognitive ability.

The rapid identification of early hits by fragment based approaches and subsequent hit-to-lead optimization represents a challenge for drug discovery. To address this challenge, we created a strategy called "DOTS" that combines molecular dynamic simulations, computer-based library design (chemoDOTS) with encoded medicinal chemistry reactions, constrained docking, and automated compound evaluation. To validate its utility, we applied our DOTS strategy to the challenging target syntenin, a PDZ domain containing protein and oncology target. Herein, we describe the creation of a "best-in-class" sub-micromolar small molecule inhibitor for the second PDZ domain of syntenin validated in cancer cell assays. Key to the success of our DOTS approach was the integration of protein conformational sampling during hit identification stage and the synthetic feasibility ranking of the designed compounds throughout the optimization process. This approach can be broadly applied to other protein targets with known 3D structures to rapidly identify and optimize compounds as chemical probes and therapeutic candidates.

This study evaluated future climate scenarios and the changes in urban flood resistance capacity in Busan EcoDelta City using the hazard capacity factor design (HCFD) model. It analyzed the flood reduction effects of both gray and green infrastructure. Despite existing flood safety systems, there is a growing need to enhance urban flood resilience due to increasing heavy rainfall, unpredictable precipitation, and frequent typhoons driven by climate change. The HCFD model predicted urban flood volumes of Busan Eco-Delta City and analyzed the effectiveness of gray and green infrastructure in flood control. A stormwater management model (SWMM) simulated urban flood resistance capacity under the SSP1-2.6 climate change scenario. Results indicate that for an anticipated 500 mm rainfall over 3 h, green infrastructure can mitigate floods by 9 % to 17.6 %, while gray infrastructure can reduce flooding by 24 % to 32.1 %. The integration of gray and green infrastructure leads to an overall flood mitigation ranging from 47.1 % to 63.3 %. A notable contribution of this research is its predictive analysis of future flood scenarios using model-based scenario analysis and decision support algorithms, offering valuable insights into changes in urban flood resistance capacity and strategies for effective flood control decision-making.
