Evaluating diagnostic indicators of urogenital Schistosoma haematobium infection in young women: A cross sectional study in rural South Africa
2018
BackgroundUrine microscopy is the standard diagnostic method for urogenital S. haematobium infection. However, this may lead to under-diagnosis of urogenital schistosomiasis, as the disease may present itself with genital symptoms in the absence of ova in the urine. Currently there is no single reliable and affordable diagnostic method to diagnose the full spectrum of urogenital S. haematobium infection. In this study we explore the classic indicators in the diagnosis of urogenital S. haematobium infection, with focus on young women.MethodsIn a cross-sectional study of 1237 sexually active young women in rural South Africa, we assessed four diagnostic indicators of urogenital S. haematobium…
Oxovanadium(IV) complexes with [ONNO]-chelating ligands as catalysts for ethylene homo- and copolymerization
2014
Oxovanadium(IV) complexes with (ONNO)-type tetradentate Schiff base ligands: salen, acacen, aceten, acetph (H2salen = N,N'-ethylenebis(salicylideneimine), H2aceten = N,N'-ethylenebis(2-hydroxyacetophenoneimine), H2acacen = N,N'-ethylenebis(acetylacetonimine), H 2 acetph = N ,N ' -phenylene-1,2-b is (2-hydroxyacetophenoneimine)), were the first time investi- gated in ethylene polymerization and ethylene/1-octene copo- lymerization processes. In general, all these complexes are moderately active precatalyst for ethylene polymerization up- on activation with EtAlCl2 and they give high molecular weight linear polyethylenes. Their activity in copolymeriza- tion was found relatively low. However,…
Ethylene homo- and copolymerization catalyzed by vanadium, zirconium, and titanium complexes having potentially tridentate Schiff base ligands
2021
Abstract New potentially tridentate Schiff base ligands, 2-[({4-[(3-N,N-dimethylamino)propyl] phenyl}imino)methyl]-4,6-di-tert-butylphenol (L1H) and 2-[{2-(N-phenyl-N-methylaminomethyl)-phenylimino}-methyl]-4,6-di-tert-butylophenol (L2H) were prepared and after deprotonation they were reacted with VOCl3 or MCl4 (where M = Zr or Ti) to produce corresponding complexes (L1-V, L2-V, L1-Zr, L2-Ti) with good yields. All new compounds were characterized by the 1H and 13C NMR as well as FTIR spectroscopic methods. Upon activation with Et2AlCl or EtAlCl2, both the vanadium complexes exhibited exceptionally high catalytic activities in the ethylene polymerization (up to 69,000 kg/(molV⋅h) for L1-V an…
Elder Abuse in Live-in Migrant Carer Arrangements
2021
This chapter focuses on an issue rarely addressed in research: abuse and protection against abuse in live-in migrant carer (LIMC) arrangements. Based on a secondary analysis of data collected in LIMC arrangements in Germany, potential risks of abuse and protective factors against abuse are identified. The chapter shows that questions about abuse and protection against abuse in these arrangements have to be analyzed in the context of complex, interrelated factors, structures and processes. There is no clear answer as to whether LIMC arrangements increase or decrease the risk of abuse and neglect of older dependent people. Aside from the existing taboo against abuse in home-based care in old …
Ceràmiques hel·lenístiques del segle III a.E. a les comarques septentrionals del País Valencià
2017
En aquest treball estudiem les escasses troballes de ceràmiques hel·lenístiques a les comarques septentrionals del litoral valencià que poden datar-se entre la darreria del s. IV i el III, amb anterioritat a l’arribada massiva de les produccions universals (campaniana A i B).
Ciència i racionalitat
2004
Des que es constitueix la ciència moderna, la filosofia, en la seua branca epistemològica, s'ha preocupat de fonamentar aquest coneixement i explicar-ne la naturalesa, però és al segle XX quan la Teoria de la Ciència, amb l'ajut de la lògica, enceta l'anàlisi de l'estructura formal de les teories científiques. Aquesta anàlisi conté dues línies fonamentals: l'una sintàctica: l'estructura de les teories, els tipus d'enunciats que intervenen, el raonament, els principis del mètode ... ; l'altra semàntica: el significat dels termes que intervenen en les teories, llur base empírica i llur traducció teòrica.
L'estudi històric de les societats naturalistes en contexts locals: el cas valencià dins el cas espanyol
2004
Al llarg de les primeres dècades del segle XX, les activitats naturalistes al País Valencià assoliren un nivell reeixit pel que fa a llur qualitat i intensitat. Aquest fet anà acompanyat d'un desenvolupament considerable de l'associacionisme naturalista. L'article fa un resum d'aquest procés i l'insereix dins el context general d'Espanya. A més, suggereix algunes possibilitats per tal de portar llum, per mitjà d'aquest tipus d'estudis, a uns altres problemes relacionats amb la dimensió social del coneixement naturalista, com ara les relacions entre professionals i aficionats, la creació de coneixement general en un context local i la inserció del procés associatiu en les particularitats soc…
Testing cognition and rehabilitation in unilateral neglect with wedge prism adaptation: multiple interplays between sensorimotor adaptation and spati…
2014
Spatial neglect is a neurological condition characterised by deficits for perceiving, attending, representing, and/or performing actions within their left-sided space, responsible for numerous debilitating effects in everyday life, for poor functional recovery, and for decreased ability to benefit from treatment. Exposure to a right lateral displacement of the visual field (induced by a simple target-pointing task with base-left wedge prisms) is known to directionally bias visuomotor coordination and can be compensated by both sensorimotor adaptation and cognitive processes. Sensorimotor adaptation gives rise to after-effects whose duration is amplified in neglect patients and has been repe…
Reducing Visuospatial Pseudoneglect in Healthy Subjects by Active Video Gaming
2023
Pseudoneglect phenomenon refers to a condition in which healthy subjects tend to perceive the left side of exactly bisected lines as being slightly longer than the right one. However, behavioural data showed that athletes practising an open-skill sport display less pseudoneglect than the general population. Given the fact that so-called exergames (also known as active video games) are platforms designed to fully mimic sport activity, this work intends to investigate whether and how a one-week training period of exergame open-skill sport can determine a similar decrease in pseudoneglect. Fifteen healthy participants (non-athletes) responded to a visuospatial attention task and a control memo…
The Child Neglect Assessment technique (C.N.A.). A path of the S.I.P.Ped
2022
Lo studio presenta il percorso di validazione di una specifica tecnica di assessment del child neglect rivolta a genitori di bambini di età compresa tra 3 e 9 anni, e che risulta articolata in due specifici strumenti di osservazione. Questa tecnica si fonda su uno specifico modello teorico-operativo costruito in riferimento alla prospettiva della Psicologia pediatrica, che identifica la causa del child neglect nella presenza di una disregolazione della competenza genitoriale, e quindi, nella gestione delle funzioni genitoriali di caregiving, scaffolding e coping. La tecnica presenta un particolare punto di forza: la capacità di intercettare i segnali di una possibile condizione di child neg…
