The term sustainability has grown increasingly popular as development experts seek to measure the long-term impacts of their projects. Although there is no commonly agreed definition sustainability, word become a common catchphrase. It often used describe desired goal lasting change within institutions, communities, and We provide tool aid in evaluation have applied our indicators two specific projects demonstrate utility. Mise à l'épreuve de la durabilité pour les projets développement Le...

Background NAC transcription factors play important roles in the regulation of plant growth, development, abiotic and biotic stress responses. The transcriptional level MdNAC s different tissues under various treatments was determined to provide a solid foundation for studying function s. Methods Thirty-two full-length cDNA sequences Md were isolated by homologous comparison RT-PCR confirmation, obtained deduced amino acid analyzed with bioinformatics methods. prediction subcellular...

Abstract In order to address population aging and the healthy China strategy, this paper takes three provinces one city in Yangtze River Delta urban agglomeration as empirical target. Firstly, using 2010 2020 census data, taking coefficient density of elderly basic research indexes, adopts center gravity migration model standard deviation ellipse outline spatial evolution path population. Second, data recreational tourism sites each prefecture-level from 2016 2022, closest neighbor index is...

Under a carbon tax, with the constraint of emissions reduction, by establishing game theoretical models for low-carbon supply chain, article investigates how tax rate and risk aversion degree may affect retail price, product emission degree, profits manufacturer, retailer, entire chain. The results show that chain profit in centralized are higher than those decentralized With risk-averse product’s will further decrease. increased aversion, manufacturer's total channel decrease, but...

The purpose of this study was twofold: to validate the College Teachers’ Academic Frustration Tolerance (CTAFT) Questionnaire and Performance (CTAP) explore relationship between frustration tolerance academic performance among college teachers. A total 25 experts were recruited modify both questionnaires, results showed that questionnaires had good content validity. Exploratory factor analysis provided further evidence supporting reliability CTAFT CTAP, suggesting instruments are reliable...

The teacher’s pets are a common occurrence in the field of education. To investigate preferences teachers exhibit toward certain children, study focused on kindergarten and employed mixed research methodology. Initially, qualitative interviews were conducted with 15 to identify specific criteria influencing teacher preferences. Subsequently, A comprehensive model was developed through questionnaire survey involving 463 participants. This encapsulated 32 distinct indicators, categorized into...

In the context of regular epidemic prevention and control, this paper considers a two-stage tourism supply chain consisting scenic spot that attracts tourists through advertising travel agency invests in service improvement prevention. By establishing theoretical game models chain, we investigate how level can affect retail price, product level, profits chain. The results show agencies could improve consumers' preferences, expand market demand for products, efficiency to achieve win-win...

Massive techniques have been evaluated for developing different pest control methods to minimize fertilizer and pesticide inputs. As "push-pull" strategy utilizes generally non-toxic chemicals manipulate behaviors of insects, such is considered be environmentally friendly. "Push-pull" has extraordinarily effective in controlling stem borers, the identification new "pushing" or "pull" components against borers could significantly helpful.In this study, results field trapping assay behavioral...

The photosynthesis effect of arbuscular mycorrhizal fungi (AMF) on mulberry was evaluated in karst rocky desertification area. Three-month-old sterile saplings were transplanted area and inoculated with Gigaspora rosea . Some growth parameters indexes measured to study the physiological responses after inoculating for 1 year. results showed mulberries that AMF had greater height, larger stem diameter leaf area, more number per plant, fibrous root biomass shoots roots, as well higher...

Background AP2/ERF transcription factors are involved in the regulation of plant growth, development, and stress responses. Our research objective was to characterize novel apple ( Malus × domestica Borkh.) genes encoding response. The transcriptional level different tissues under various biotic abiotic determined provide valuable insights into function apple. Methods Thirty full-length cDNA sequences were isolated from ‘Zihong Fuji’ cv. Zihong Fuji) via homologous comparison RT-PCR...

Diospyros leei Yan Liu, S. Shi & Y.S. Huang, a new species of Ebenaceae from limestone areas in Guangxi, China is described and illustrated. It similar to D. rostrata chunii, but differs by its 3.5–12 cm long 1–1 wide leaf blade with cuneate or obtuse base; 4-lobed calyx; fruit which elliptic, ca. 3.3 diam. the middle, glabrous sometimes sparsely brown strigose, apex being prominently rostrate, beak longer than 1 cm.

The purpose of this study was 2-fold: to validate the Private Kindergarten Teachers' Intention Remaining (PKTIR) Questionnaire and Factors (FTIR) Questionnaire, comparative explore effects organizational individual psychological factors in China. A total 22 experts were recruited modify both questionnaires. results showed that questionnaires had instruments are reliable valid. Then, a 582 kindergarten teachers comparison between factors. from structural equation model suggested influence on...

The sterile insect technique (SIT) may reduce pest populations by allowing sufficient amount of irradiation-induced males to mate with wild females whilst maintaining mating ability comparable males. Although the SIT methods are well understood, optimal sterilizing dose and processing development stage for application vary among species. To ensure effective control programs, effects irradiation on physiology, behavior, gene function in target species should be defined, however, little is...

Rieske iron-sulfur protein (RISP) is a key subunit of mitochondrial complex III which plays an important role in the respiratory electron transport chain. The complete cDNA RISP was cloned from Spodoptera exigua by real time quantitative PCR and rapid-amplification ends (RACE) technology named as SeRISP (GenBank Accession Number: JN992290). Multiple alignments creation phylogenetic tree revealed that RISPs are highly conserved among different insects, region mainly located at C-terminal...

To investigate the choice of return strategy and its impact on a dual‐channel supply chain, game model is constructed to analyze equilibrium outcomes five scenarios: no returns allowed, refunds without returns, allowed but shipping insurance, insurance purchased by manufacturer, consumer. The study found that manufacturers offering refund policies generate more sales in direct online channel, while retailers choose reduce retail price their products. It important note reductions have very...
