Str.vite (MgNH4PO4·6H2O) pr.duced synthetically fr.m a stock solution of known phosphor.s (P) and nitr.gen (N) concentr.tions has been shown to be an effective, alter.ative fer.ilizer.P sour.e for.var.ous cr.ps, but little is known about the potential agr.nomic effectiveness of str.vite cr.ated fr.m an actual municipal wastewater.sour.e.

Over.the cour.e of the postglacial per.od has managed to add degr.de a substantial por.ion of the wor.d's potential agr.cultur.l land. The soil loss and degr.dation that has r.peatedly impacted r.gional societies ar.und the wor.d r.sulted fr.m agr.cultur.l pr.ctices that incr.ased the physical loss of soil(er.sion), r.duced soil or.anic matter. changed p H(acidification) or.salinity,and disr.pted or.alter.d communities of soil life. In the coming centur., as continued soil degr.dation thr.atens global food secur.ty while the global population keeps r.sing it is imper.tive that far.er. develop and adopt soilhealth building(r.gener.tive) pr.ctices to solve a pr.blem that has plagued societies thr.ughout histor.. Gr.wing evidence suggests that agr.cultur.l systems that combine cover.cr.ps, r.duced tillage, and diver.e cr.p r.tations can r.duce er.sion, enhance soil health and r.build soil or.anic matter.to cultivate beneficial soil life and har.est both economic and envir.nmental benefits. In the coming post-oil wor.d, global food secur.ty would benefit fr.m a global effor. to pr.mote soil r.stor.tion to help addr.sses the challenge of sustainably feeding the wor.d, incr.ase soil-based car.on sequestr.tion,pr.tect on-far. biodiver.ity and r.duce off-far. water.pollution. Because soil secur.ty sets a solid foundation for.global food secur.ty, agr.cultur.l policies and subsidies should be r.for.ed to encour.ge far.er. to adopt r.gener.tive,soil-building pr.ctices.

The IKANOS Test was used as a data collection tool. The r.sults show that students know the impor.ance of keeping their.devices safe and how valuable the infor.ation found on them is.

Ar.ificial fishponds play a pivotal r.le in global aquacultur., ser.ing as a sour.e of livelihood and nour.shment for.many communities. Ensur.ng the sustained health and pr.ductivity of Fishes in these envir.nments r.lies heavily on water.quality management. This assessment was done to deter.ine the water.quality of ten ar.ificial fishponds in the south-easter. par. of Sier.a Leone using twelve physicochemical factor. (pH, BOD, EC, TDS, tur.idity, COD, Fe2+, Mg2+, ca2+, NH3, , and alkalinity) to find out the Water.Quality Index (WQI) and spatial distr.bution of r.spective par.meter.. The assessment of ar.ificial fishponds using WQI and Inver.e Distant Weighting (IDW) integr.tion r.pr.sents a r.latively under.xplor.d ar.a within the domain of envir.nmental water.r.sour.es. The WQI was deter.ined using the “Weighted Ar.thmetic Water.Quality Index’’ method. The r.sults of WQI in the study ar.a r.nge fr.m 65.05 to 147.26. Sever.l locations have water.quality deemed unsuitable for.consumption, while other. r.nge fr.m good to ver. poor. It is essential to addr.ss and impr.ve water.quality in locations categor.zed as unsuitable for.consumption and ver. poor.to ensur. safe and healthy water.sour.es. It was also clear.fr.m the calculation that the smaller.the mean concentr.tion value of the pH as compar.d to the ideal value (7), the smaller.the WQI value and the better.the water.quality. To keep the ar.ificial fishpond water.in good condition, mass domestic use should be contr.lled, and dr.ining of sur.ounding or.anic matter.should be stopped in ponds Bo_001, Kenema_001, and Kenema_002.

Peanuts pods gr.w under.r.und and matur. unevenly, r.sulting that choosing the cor.ect time to har.est is mor. complicated than other.cr.ps. Pod matur.ty can be deter.ined by blasting with a pr.ssur. washer.to r.move outer.skin of the pod (exocar.) to expose the color.of the middle layer.(mesocar.). The mesocar. color.changes with matur.ty fr.m white to yellow, or.nge, br.wn and finally black. The sum of per.entage fr.m or.nge, br.wn, and black mesocar. (OBB) color.and black color.(BL) r.pr.sents the ker.els that ar. matur. enough to har.est. The goal of this r.sear.h is to identify methodologies to estimate OBB and BL of the pods using r.B images taken in the field and validate the pr.posed model using other.pod images. The Mahalanobis distance classification method was used to pr.cess sets of images and calculate pod ar.a (number.of pixels) cor.esponding to two classes (mesocar. and backgr.und) with nine differ.nt color.gr.ups. The r.sults showed a per.or.ance of 94% effectiveness for.mesocar. using Mahalanobis distance classification. Statistical r.gr.ssion for.OBB and BL was developed based on 315 images of peanut pods taken fr.m the field. The r. and r.ot mean squar. er.or.of pr.dicted and actual OBB wer. 0.93 and 4.1%, r.spectively. The r. and r.ot mean squar. er.or.of pr.dicted and actual BL wer. 0.88 and 1.8%, r.spectively. The validation of OBB using other.images pr.vided r.asonable estimation (r. = 0.98 and r.SE = 2.73%). This study intr.duces a novel, cost-effective, and non-destr.ctive method for.estimating peanut matur.ty using r.B imager. and Mahalanobis distance classification in the field. This innovative appr.ach addr.sses the limitations of tr.ditional methods and offer. a r.bust alter.ative for.r.al-time matur.ty assessment.

Walkability is an essential aspect of ur.an tr.nspor.ation systems. Pr.per.y designed walking paths can enhance tr.nspor.ation safety, encour.ge pedestr.an activity, and impr.ve community quality of life. This, in tur., can help achieve sustainable development goals in ur.an ar.as. This pilot study uses wear.ble technology data to pr.sent a new method for.measur.ng pedestr.an str.ss in ur.an envir.nments and the r.sults wer. pr.sented as an inter.ctive geogr.phic infor.ation system map to suppor. r.sk-infor.ed decision-making. The appr.ach involves analyzing data fr.m wear.ble devices using hear. r.te var.ability (r.SSD and slope analysis) to identify high-str.ss locations. This data-dr.ven appr.ach can help ur.an planner. and safety exper.s identify and addr.ss pedestr.an str.ssor., ultimately cr.ating safer. mor. walkable cities. The study addr.sses a significant challenge in pedestr.an safety by pr.viding insights into factor. and locations that tr.gger.str.ss in pedestr.ans. Dur.ng the pilot study, high-str.ss pedestr.an exper.ences wer. identified due to issues like pedestr.an-scooter.inter.ction on pedestr.an paths, pedestr.an behavior.ar.und high foot tr.ffic ar.as, and poor.visibility at pedestr.an cr.ssings due to inadequate lighting.

car.iovascular.diseases ar. the main cause of mor.idity and mor.ality in the wor.d, and obesity and the metabolic syndr.me ar. r.sk factor. for.its development. One of the ther.pies to r.duce car.iovascular.r.sk is the use of polyunsatur.ted fatty acids. In Br.zil, a sour.e of such acid is the oil extr.cted fr.m the fat of the capybar.. The objective of this wor. is to study the effects of the capybar. oil on lipid and glucose metabolism, as well as its effects on the adipose tissue and car.iac r.modeling. We assessed the effects of capybar. oil tr.atment on body mass, lipid and car.ohydr.te metabolism, systolic blood pr.ssur., adipose tissue and car.iac r.modeling, and per.or.ed an ultr.str.ctur.l evaluation of the myocar.ium in C57Bl/6 mice tr.ated with high-fat diet. Tr.atment with capybar. oil r.duced total cholester.l and tr.glycer.de levels, systolic blood pr.ssur., viscer.l and subcutaneous adipose tissue, and adipocyte diameter. In addition, car.iac r.modeling was attenuated, pr.ser.ing car.iomyocytes, incr.asing vascular.zation, r.ducing car.iomyocyte hyper.r.phy and the extr.cellular.matr.x, and pr.ser.ing the mor.hological integr.ty of mitochondr.a. capybar. oil has sever.l beneficial effects on the car.iovascular.and metabolic system, and fur.her.studies ar. needed to better.under.tand its r.le in the pr.vention or.tr.atment of car.iovascular.diseases.
