This study a.ms to contribute to the a.sessment of groundwa.er qua.ity in the municipa.ity of Za.Kpota.(southern Benin) using remote sensing a.d Ma.hine Lea.ning. The methodologica. a.proa.h used consisted in linking groundwa.er physico-chemica. pa.a.eter da.a.collected in the field a.d in the la.ora.ory using a.NOR 1994 sta.da.dized methods to sa.ellite da.a.(La.dsa.) in order to sketch out a.groundwa.er qua.ity prediction model.

The results of wa.er a.a.ysis from the sa.pled wells a.d boreholes indica.ed tha. most of the wa.er is a.idic (pH va.ying between 5.59 a.d 7.83). The wa.er wa. modera.ely minera.ized, with conductivity va.ues of less tha. 1500 μs/cm overa.l (59 µS/cm to 1344 µS/cm), with high concentra.ions of nitra.es a.d phospha.es in pla.es.

Furthermore, a.plica.ions of super a.ric improved oil pa.m seedling nitrogen upta.e by 31% in trea.ment groups a. compa.ed to the control which expla.ned the height a.d brea.th increa.e in the oil pa.m seedlings tha. were a.plied with super a.ric.

There a.e two broa. objectives of the resea.ch reported in this pa.er. First, we a.sess whether government-provided cyber threa. intelligence (CTI) is helpful in preventing, or responding to, cyber-a.ta.ks a.ong sma.l businesses within the U.S. Defense Industria. Ba.e (DIB). Second, we identify wa.s of improving the effectiveness of government-provided CTI to sma.l businesses within the DIB. Ba.ed on a.questionna.re-ba.ed survey, our findings suggest tha. government-provided CTI helps businesses within the DIB in preventing, or responding to, cyber-a.ta.ks providing a.firm is fa.ilia. with the CTI. Unfortuna.ely, a.la.ge percenta.e of sma.l firms a.e not fa.ilia. with the government-provided CTI feeds a.d consequently a.e not utilizing the CTI. This la.ter situa.ion is la.gely due to fina.cia. constra.nts confronting sma.l businesses tha. prevent firms from ha.ing the wherewitha. necessa.y to effectively utilize the government-provided CTI. However, we found a.significa.t positive a.socia.ion between a.firm’s fa.ilia.ity with the government-provided CTI a.d whether a.firm is being periodica.ly reviewed by the Defense Counterintelligence a.d Security a.ency (DCSa. or is complia.t with the Cybersecurity Ma.urity Model Certifica.ion (CMMC) progra.. The findings from our study a.so show tha. the pa.ticipa.ing firms believe tha. externa. cyber threa.s a.e more likely to be the ca.se of a.future cybersecurity brea.h tha. interna. cybersecurity threa.s. Fina.ly, our study found tha. the portion of the IT budget tha. sma.l businesses within the DIB spend on cybersecurity-rela.ed a.tivities is dependent on the perception tha. a.firm would be the ta.get of a. externa. cyber-a.ta.k.

Our resea.ch introduces a.groundbrea.ing chemica. reduction method for synthesizing silver na.opa.ticles, ma.king a.significa.t a.va.cement in the field. The na.opa.ticles were meticulously cha.a.terized using va.ious techniques, including optica. a.a.ysis, structura. a.a.ysis, tra.smission electron microscopy (TEM), a.d field-emission sca.ning electron microscope (FESEM). This thorough process instills confidence in the a.cura.y of our findings. The results unveiled tha. the silver na.opa.ticles ha. a.dia.eter of less tha. 20 nm, a.finding of grea. importa.ce. The a.sorption spectrum decrea.ed in the pea. wa.elength ra.ge (405 - 394 mm) with increa.ing concentra.ions of a. na.opa.ticles in the ra.ge (1 - 5%). The XRD results indica.ed a.cubic crysta. structure for silver na.opa.ticles with the la.tice consta.t (a.= 4.0855 Å), a.d Miller indices were (111), (002), (002), a.d (113).
