Here, we investigated the role of probiotics on growth (weight gain, specific growth rate), survivability, feed utility (feed conversion ratio), hemoglobin, glucose, structure of erythrocytes (cellular and nuclear abnormalities), and gut morphology of striped catfish (<i>Pangasianodon hypophthalmus</i>) reared in different salinities. The fingerlings (8.10 ± 0.20 g) were evenly distributed four different salinities (0, 4, 8 and 12 ppt) in three replicates with and without probiotics supplementation for 56 days. Multi-species probiotics containing <i>Bacillus subtilis</i> (5 × 10⁹ cfu/ml), <i>B. thuringiencis</i> (4 × 10⁹ cfu/ml), <i>Lactobacillus plantarum</i> (5.8 × 10⁹ cfu/ml), and <i>L. buchneri</i> (6.5 × 10⁹ cfu/ml) were used as 1.0 mL/L at the alternate day. The results of this study indicated that survivability, growth and feed utility were negatively affected with the increased salinity, however multi-species probiotics significantly ameliorated the negative effects of salinity. Moreover, multi-species probiotics significantly improved hemoglobin (g/dL) and glucose (mg/dL) level at different salinity in comparison with the non-probiotics treated groups. Frequencies of cellular and nuclear abnormalities of erythrocytes were increased significantly with the increase of salinity in non-probiotics groups, while those significantly declined in multi-species probiotics treated groups. Increased salinity level suppressed the immune response indices, while probiotics supplementation significantly improved the gut immune response irrespective of salinity level. Taken altogether, the current study revealed that application of multi-species probiotics can be an effective tool to reduce salinity stressors and improve growth and health status by upgrading hemato-biochemical profile and intestinal morphology of <i>P. hypophthalmus</i> at higher salinity.</p>","PeriodicalId":14121,"journal":{"name":"International Journal of Environmental Research","volume":"296 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These analyses revealed that the nanoparticles had globular morphology, a crystallite size of 14 nm, a bandgap of 2.45 eV, and stability at high temperatures. Fluorescence emission at 548 nm wavelength exhibits high sensitivity and selectivity for imidacloprid over other pesticides with complete fluorescent quenching at 2 × 10^–4 M concentration of imidacloprid. Stern–Volmer equation and thermodynamic parameters applied to the experimental data over a temperature range of 20–50 °C provide the K_sv value in the range of 1.56 × 10⁵ to 2.69 × 10⁵ M⁻¹ and indicate strong interactions, dynamic, spontaneous, and endothermic quenching process. Furthermore, the excellent salient features and notably the unaffected performance even in the presence of various anions, fertilizer, and binary mixture of pesticides often sprayed on plants, will pave the way for the development of rapid, affordable, selective fluoroprobe for onsite monitoring of imidacloprid.

Litterbags were used to collect the leaves for a year while the amount of nitrogen, phosphorus, calcium, sulfur, carbon, magnesium, and potassium levels was measured monthly for both species. The annual mean weight of all components of litter was found to be 4056.56 g for pine and 4106.67 g for elm trees. The results showed that the greatest fall of pine needles was recorded in September, while the highest fall of elm leaves was measured in November. The specific leaf area of elm and pine was calculated to be 169.38 and 29.96 cm²/g, respectively. The leaf area index for pine and elm was 0.91 and 7.99, respectively. There was no statistically significant difference between pine and elm trees in the leaf amount and total litter. However, the crown area of pine and elm trees had a direct effect on the amount of total litter produced (R² = 0.72 and 0.60 respectively). There was a significant difference between the two species in organic matter percentage, while there was no significant difference in the carbon, calcium, and magnesium content. The specific leaf area of elm was higher than pine, making it better in this index. According to the amount of annual litter production of two species calculated in this research, it can be said that in the city of Yazd, pine and elm trees produce at least 158.9 and 804.5 tons of litter per year respectively. Since the minimum cost of litter collection per hectare of tree plantations in the city is $150, collecting pine and elm litter will cost the municipality $14,700 and $73,500, respectively. Our study showed that contrary to popular belief, pine needles play an important role in total leaf litter produced in arid regions like Yazd.

During the last 4 days, however, the average temperature of more humid soil was obviously elevated, especially in the zones receiving less energy input. It was attributed to the fact that soil temperature was mainly determined by heat conduction, and soil pores still occupied by water were more beneficial for heat conduction, leading to the promoted evaporation of <i>n</i>-alkane and therefore eventual remediation efficiency.

Their type, concentration and diversity have important implications on various atmospheric processes however the limited understanding of bioaerosols-cloud-climate connection has resulted in existing uncertainty in climate models. Bioaerosols as ice nucleating particles (INPs) and cloud condensation nuclei (CCN) govern precipitation initiation, cloud formation and thus the complex hydrological cycle. Homogeneous nucleation takes place at colder temperatures (&lt; − 38 ℃), while owing to their unique properties, certain ice nucleating bioaerosols can initiate freezing at much warmer temperatures (≧ − 10 °C) and thus are important for precipitation initiation through heterogenous nucleation mechanism. Flux of bioaerosols from diverse terrestrial and marine sources lead to their build-up in the atmosphere but rare bioaerosols act as CCN and INP. These rare characteristics of bioaerosols remain largely unexplored and need further attention and research. This work presents fundamental insights on the role of bioaerosols in cloud formation and ice nucleation mechanism along with an overview on the types, diversity and sources of bioaerosols. Most studies reviewed here on bioaerosol-cloud-climate connections are restricted to from specific research groups. Bioaerosol research is still in evolving stage and limited usage of advanced techniques of sampling and characterization is noticed particularly in developing countries.

One of the efficient solutions to address this issue is allowing more solar access into interiors and thus making the most of daylight and solar heat gain. Accordingly, this paper presents a novel approach to integrate daylight optimization in both urban environments and buildings’ interiors via the development and application of a custom algorithm based evolutionary computation. This ultimately allows more daylight penetration into urban canyons [vertical daylight illuminance (VDI)] and, subsequently, improves indoor visual comfort [useful horizontal illuminance level (HIL)]. This can also reduce the associated lighting and heating (during winter) energy use of buildings. Furthermore, investigating the correlation between indoor and outdoor illuminance levels aims to bridge the gap between daylight requirements at the urban planning and building scale. A multi-objective evolutionary algorithm-based assessment using computational simulation of design variables is conducted. This determines the extent to which each urban morphology can affect daylight access in both indoor and outdoor environments.
