En este trabajo se realiza una descripción del régimen legal de los contratos participación público privada (PPP). Asimismo, presentan las características principales PPP. Luego analiza la programación presupuestaria proyectos bajo esa modalidad desde 2018 en adelante. También abordan problemas que sufrieron iniciativas aquel año por turbulencias económicas y financieras atravesó el país, que, ...

Context Polymorphism at the insulin gene (INS) VNTR shows variable associations with childhood BMI in different populations. Objective To study INS VNTR associations with body composition and insulin secretion in children. Design Prospective birth cohort study Participants 947 children genotyped for the INS VNTR Main outcome measures Whole body DXA at 9 years to estimate height-corrected fat ma...

There is limited evidence on the prospective association of time spent in activity intensity (sedentary (SED), moderate (MPA) or vigorous (VPA) physical activity) and dietary intake with adiposity indicators in young people. This study aimed to assess associations between (1) baseline objectively measured activity intensity, dietary energy density (DED) and 4-year change in adiposity and (2) 4-...

Real-time digital simulation of power systems is incredibly important for the testing appropriate control and protection strategies in system industry. However, case which one single model can be used offline simulations then realtime studies rare, if existing at all, due to lack adequate standard development industry or adoption successful standards elsewhere. A direct consequence this portabi...

During vertebrate gastrulation, the body axis is established by coordinated and directional movements of cells that include epiboly, involution, and convergence and extension (C&E). Recent work implicates a non-canonical Wnt/planar cell polarity (PCP) pathway in the regulation of C&E. The Drosophila atypical cadherin Flamingo (Fmi) and its vertebrate homologue Celsr, a 7-pass transmembrane prot...

A temperature-dependent extended x-ray-absorption fine structure investigation of La1−xCaxMnO3 is presented for the concentration range that spans the ferromagnetic-insulator FMI to ferromagnetic-metal FMM transition region, x=0.16, 0.18, 0.20, and 0.22; the titrated hole concentrations are slightly higher, y=0.2, 0.22, 0.24, and 0.25, respectively. For this range of Ca concentrations the sampl...

OBJECTIVE Growth hormone (GH) affects linear growth and body composition, by increasing the secretion of insulin-like growth factor-I (IGF-I), muscle protein synthesis and lipolysis. The intake of protein (PROT) as well as the specific amino acids arginine (ARG) and lysine (LYS) stimulates GH/IGF-I secretion. The present paper aimed to investigate associations between PROT intake as well as int...

OBJECTIVES This study sets out to investigate the intergenerational associations between the body mass index (BMI) of parents and the body composition of their offspring. METHODS The cross-sectional data were analyzed for 511 parent-offspring trios from London and south-east England. The offspring were aged 5-21 years. Parental BMI was obtained by recall and offspring fat mass and lean mass w...
