Working conditions in Western countries have changed dramatically in the last twenty years, witnessing the emergence of new forms of employment contracts. The number of "standard" fulltime permanent jobs has decreased, while non-standard work arrangements such as temporary, contingent or part-time contracts have become much more common. This paper analyses the impact of temporary contracts and ...

In this research injector, cleaner, and camphor were blended with premium motor spirit (PMS). Physicochemical properties effects on performance exhaust emission spark ignition engines investigated. Samples injector cleaner show the best physicochemical as compared to sole petrol samples having a density of 0.72706kg/m2 (I5), flashpoint 47oC by sample (I5, I10, I15,) 48oC I25, 1.7 viscosity, ana...

Estudam‑se os restos faunísticos da C.2A do Locus I15, recuperados nos níveis de ocupação Calcolítico tardio com cerâmicas campaniformes grupo estilístico Palmela (Fase IC ‑cerca 2250 cal BC) povoado Chibanes (Palmela). Nos mamíferos observou‑se claro predomínio animais domésticos, representados por ordem decrescente pelo porco, seguido dos caprinos (ovelhas e cabras) boi doméstico. A alimentaç...

UNLABELLED Both HIV-1 virions and infected cells use their surface regulators of complement activation (RCA) to resist antibody-dependent complement-mediated lysis (ADCML). Blockage of the biological function of RCA members, particularly CD59 (a key RCA member that controls formation of the membrane attack complex at the terminal stage of the complement activation cascades via all three activat...

We discuss and review literature on the macroeconomic effects of epidemics pandemics since late twentieth century. First, we cover role health in driving economic growth well-being standard frameworks for assessing burden infectious diseases. Second, sketch a general theoretical framework to evaluate trade-offs policy makers must consider when addressing diseases their repercussions. In so doin...

In this paper, heterocyclic hexagonal rings were prepared for pyrimidine derivatives [I9-I16] by reacting a mole of gluconate with cyanoguanidine and using ethanol as solvent. The accuracy the compositions compounds was confirmed measuring physical properties, including melting point, color, molecular weight, well through spectroscopic measurements, infrared spectrum, proton nuclear magnetic re...

Comorbidity is defined as the presence of one or more chronic non-communicable diseases. Recentlymany articles have illustrated that covid positive person with noncommunicable disease has poor health outcome. Covid patients comorbidity such diabetes, heart diseases and hypertension are vulnerable to develop a severe condition. For this study we taken data from national family survey 2015-16 (NF...
