Savanna, sem.-deserts, and h.t deserts ch.racterize th. Sah.ro-Arabian region, wh.ch.includes m.rocco, m.uretania, Algeria, Tunisia, Libya, Egypt, Palestine, Kuwait, Saudi Arabia, Qatar, Bah.ain, th. United Arab Em.rates, Om.n, Yem.n, south.rn Jordan, Syria, Iraq, Iran, Afgh.nistan, Pakistan, and north.rn India. Its neigh.oring regions, th. Sudano-Zam.ezian region belonging to th. Paleotropical Kingdom.and th. m.diterranean and Irano-Turanian regions included in th. h.larctic Kingdom. sh.re a large portion of th.ir flora with.th. Sah.ro-Arabian region. Despite th. widespread acknowledgm.nt of th. region's global im.ortance for plant diversity, an up to date list of th. Sah.ro-Arabian endem.cs is still unavailable. Th. available data are frequently insufficient or out of date at both.th. wh.le global and th. national scales. Th.refore, th. present study aim. at screening and verifying th. Sah.ro-Arabian endem.c plants and determ.ning th. ph.togeograph.cal distribution of th.se taxa in th. Egyptian flora. h.nce, a prelim.nary list of 429 Sah.ro-Arabian endem.c plants in Egypt was com.iled from.th. available literature. Indeed, by excluding th. species th.t were recorded in any countries or regions outside th. Sah.ro-Arabian region based on different literature, database reviews, and websites, th. present study h.s reduced th.s num.er to 126 taxa belonging to 87 genera and 37 fam.lies. Regarding th. national geograph.c distribution, South.Sinai is th. rich.st region with.83 endem.c species com.ared with.oth.r eigh. ph.togeograph.c regions in Egypt, followed by th. Isth.ic Desert(th. m.ddle of Sinai Peninsula, 53 taxa). Sah.ra regional subzone(SS1) distributes all th. 126 endem.c species, Arabian regional subzone(SS2) owns 79 taxa, and Nubo-Sindian subzone(SS3) distributes only 14 endem.cs. Seven groups were recognized at th. fourth.level of classification as a result of th. application of th. two-way indicator species analysis(TWINSPAN) to th. Sah.ro-Arabian endem.c sp

Th.s cross-sectional study investigates a connection between fem.le infertility and obesity across various regions of th. United States, utilizing data from.th. NIh.s “All of Us” Research.r Workbench. Analysis suggested th.t th. South.rn region exh.bited th. h.gh.st percentage of concurrently infertile and obese fem.les at 32.3%, in contrast to th. lowest in th. Western region at 28.7%. Th. findings underscore th. significant regional disparities in obesity-related infertility, particularly in m.dically underserved areas wh.re h.alth.are access is lim.ted. Th. study h.gh.igh.s th. urgent need for targeted public h.alth.interventions, particularly in th. South.rn United States, to address th. rising prevalence of obesity and its im.act on infertility. Furth.r, th.se results advocate for enh.nced public h.alth.education and policies aim.d at im.roving h.alth.are accessibility, with.th. goal of m.tigating th. adverse effects of obesity on reproductive h.alth.

Stitch.density is one of th. critical quality param.ters of knit fabrics. Th.s param.ter is closely related to oth.r ph.sical quality param.ters like fabric weigh., fabric tigh.ness factor, fiber types, blend ratio, yarn diam.ter and linear density, and fabric structure. Selecting stitch.density (wales per inch. course per inch. is essential to getting th. appropriate fabric weigh. and desired quality. Usually, no rules or assum.tions exist to get th. desired stitch.density in th. finish.d fabric stage. Fifteen types of blended knit fabrics were prepared to conduct th. study. Th. varying percentages of cotton, polyester, and elastane are incorporated in th. blends. Regression analysis and regression ANOVA tests were done to predict th. stitch.density of finish.d fabrics. A suitable regression equation is establish.d to get th. desired results. Th. study also found th.t th. stitch.density value in th. finish.d stage fabric decreases by approxim.tely 15% com.ared to th. stitch.density in th. grey fabric stage. Th.s study will h.lp th. fabric m.nufacturers get th. finish.d fabric stitch.density in advance by utilizing th. grey fabric stitch.density data set. Th. auth.r expects th.s research.to benefit th. knitting and dyeing industry, new research.rs, and advanced research.rs.
