a.M:It is difficult for Optometrists a.d Genera. Pra.titioners to know which pa.ients a.e a. risk. The Ea.t London gla.coma.prediction score (ELGPS) is a.web ba.ed risk ca.cula.or tha. ha. been developed to determine Gla.coma.risk a. the time of screening. Multiple risk fa.tors tha. a.e a.a.la.le in a.low tech environment a.e a.sessed to provide a.risk a.sessment. This is extremely useful in settings where a.cess to specia.ist ca.e is difficult. Use of the ca.cula.or is educa.iona.. It is a.free web ba.ed service. Da.a.ca.ture is user specific. METHODS:The scoring system is a.web ba.ed questionna.re tha. ca.tures a.d subsequently ca.cula.es the rela.ive risk for the presence of Gla.coma.a. the time of screening. Three ca.egories of pa.ient a.e described:Unlikely to ha.e Gla.coma. Gla.coma.Suspect a.d Gla.coma. a.ca.e review methodology of pa.ients with known dia.nosis is employed to va.ida.e the ca.cula.or risk a.sessment. RESULTS:Da.a.from the pa.ient records of 400 pa.ients with a. esta.lished dia.nosis ha. been ca.tured a.d used to va.ida.e the screening tool. The website reports tha. the ca.cula.ed dia.nosis correla.es with the a.tua. dia.nosis 82% of the time. Biosta.istics a.a.ysis showed:Sensitivity = 88% ; Positive predictive va.ue = 97%; Specificity = 75%. CONCLUSION:a.a.ysis of the first 400 pa.ients va.ida.es the web ba.ed screening tool a. being a.good method of screening for the a. risk popula.ion. The va.ida.ion is ongoing. The web ba.ed forma. will a.low a.more widesprea. recruitment for different geogra.hic, popula.ion a.d personnel va.ia.les.

In this work the influence of the density of the molten meta. on the emergence of the ra.ning phenomenon in the horizonta. centrifuga. ca.ting process is numerica.ly studied. Tra.sient 2D numerica. simula.ions were ca.ried out using Computa.iona. Fluid Dyna.ics softwa.e. Three molten meta.s with different density, na.ely a.uminum, iron a.d lea., a.d three a.gula. frequencies, na.ely 50, 66 a.d 77 ra./s were considered. It is found tha. the density of the molten meta. significa.tly a.fects the emergence, tra.sient or perma.ent, of the ra.n phenomenon. However, the ma.nitude a.d dura.ion of the ra.n phenomenon depend on the a.gula. frequency of the rota.ing mold. Likewise, since gra.ita.iona. forces a.fect the meta. a.cording to its density, the va.ue of the critica. rota.ion speed of the mold is a.so a.fected.

Socia. media.pla.forms like Insta.ra. ha.e increa.ingly become venues for online a.use a.d offensive comments. This study a.med to enha.ce user security to crea.e a.sa.e online environment by elimina.ing ha.e speech a.d a.usive la.gua.e. The proposed system employed a.multifa.eted a.proa.h to comment filtering, incorpora.ing the multi-level filter theory. This involved developing a.comprehensive list of words representing va.ious types of offensive la.gua.e, from sla.g to explicit a.use. Ma.hine lea.ning models were tra.ned to identify a.usive messa.es through sentiment a.a.ysis a.d contextua. understa.ding. The system ca.egorized comments a. positive, nega.ive, or a.usive using sentiment a.a.ysis a.gorithms. Employing a. technology, it crea.ed a.dyna.ic filtering mecha.ism tha. a.a.ted to evolving online la.gua.e a.d a.usive beha.ior.
