Compensatory education: Long-term effects of early parental implication (and III: The C.P.C.)
2007
After describing the program of early compensatory education (from age 3 to 9), called Chicago Child-Parent Centers (CPC), this article collects and analyses the evaluation studies of that Program from a longitudinal perspective – Chicago Longitudinal Study (CLS)-, focusing primarily on methodological problems and afterwards on the short and, mainly, long terms effects, until the targeted subjects of the Program reached the age of 24. The studies confirm the Program has lasting educational (higher performance and educational achievements) and social (higher social adjustment) effects. Subsequently, it analyses which elements of the Program can produce these beneficial effects, which are bas…
Supplementary frequency regulation in non-synchronous AC system connected via MTDC
2019
Abstract In smart grid power system operation, frequency regulation is one of the most critical tasks towards power balance in the grid. This paper presents the schemes for improvement in operation of secondary loop of turbine-generator unit for frequency regulation in non-synchronous AC areas connected via multi-terminal direct current (MTDC) network. Two schemes have been discussed; (i) voltage droop based lead/lag compensator and (ii) DC power modulation at converter terminal depending upon frequency deviation from each AC area. In the first scheme, droop design based on lead/lag compensator using DC voltage deviation is introduced as supplementary signal at turbine-generator unit in eac…
Kultūras komunikācija interneta medijos: interneta portāla Satori.lv analīze (2003-2015)
2016
Bakalaura darba „Kultūras komunikācija interneta medijos: interneta portāla Satori.lv analīze (2003–2015)” pētnieciskie jautājumi ir par Satori.lv satura attīstības un maiņas tendencēm 12 gadu garumā. Pētījums balstīts uz Garija Vennela (Garry Whannel) triangulāro shēmu, kas tika modificēta, pielāgojot to minētā portāla pētniecībai. Shēmas elementu aizvietošana un tālāka noteikšana notiek, izmantojot rāmējuma analīzi, taču ar kontentanalīzi sistematizēts rakstu kopējais raksturojums un dalījums pēc žanra. Pētījuma mērķis ir uzzināt, vai un kā no pirmsākumiem ir/nav mainījusies portāla materiālu tematika, vai ir kādas tēmas pārsvars konkrētajā laikā. Pētījumā tiks izmantoti materiāli, sākot …
Lead-Lag-Shaped Interactive Force Estimation by Equivalent Output Injection of Sliding-Mode
2020
Estimation of interactive forces, which are mostly unavailable for direct measurement on the interface between a system and its environment, is an essential task in various motion control applications. This paper proposes an interactive force estimation method, based on the well-known equivalent output injection of the second-order sliding mode. The equivalent output injection is used to obtain a frequency-unshaped quantity that appears as a matched external disturbance and encompasses the interactive forces. Afterwards, a universal lead-lag shaper, depending on dynamics of the motion control system coupled with its environment, is used to extract an interactive force quantity. Once identif…
Delayed transmission of a parasite is compensated by accelerated growth.
2005
Compensatory or ‘catch-up’ growth following prolonged periods of food shortages is known to exist in many free-living animals. It is generally assumed that growth rates under normal circumstances are below maximum because elevated rates of growth are costly. The present paper gives experimental evidence that such compensatory growth mechanisms also exist in parasitic species. We explored the effect of periodic host unavailability on survival, infectivity and growth of the fish ectoparasiteArgulus coregoni. Survival and infectivity ofA. coregonimetanauplii deprived of a host for selected time periods were age dependent, which indicates that all metanauplii carry similar energy resources for …

El enriquecimiento injusto en los procedimientos de familia
2021
En las relaciones familiares post crisis de pareja pueden darse situaciones que originen el enriquecimiento sin causa de una de las partes en perjuicio de la otra. Encontramos ejemplos de ello en cuestiones como la pensión de alimentos, atribución de la vivienda familiar, o indemnizaciones por rupturas de parejas de hecho.
Increased hepatic fibrosis and JNK2-dependent liver injury in mice exhibiting hepatocyte-specific deletion of cFLIP.
2012
Chronic liver disease promotes hepatocellular injury involving apoptosis and triggers compensatory regeneration that leads to the activation of quiescent stellate cells in the liver. The deposition of extracellular matrix from activated myofibroblasts promotes hepatic fibrosis and the progression to cirrhosis with deleterious effects on liver physiology. The role of apoptosis signaling pathways in the development of fibrosis remains undefined. The aim of the current study was to determine the involvement of the caspase-8 homologue cellular FLICE-inhibitory protein (cFLIP) during the initiation and progression of fibrosis. Liver injury and fibrosis from carbon tetrachloride (CCl4) and thioa…
Architectural changes of the extracellular matrix in compensatory lung growth (540.2)
2014
Compensatory growth of the remaining lung after murine pneumonectomy (PNX) involves the structural remodeling of the peripheral acini. Although the role of stem cells and local cellular proliferati...
Deformation-induced transitional myofibroblasts contribute to compensatory lung growth
2016
In many mammals, including humans, removal of one lung (pneumonectomy) results in the compensatory growth of the remaining lung. Compensatory growth involves not only an increase in lung size, but also an increase in the number of alveoli in the peripheral lung; however, the process of compensatory neoalveolarization remains poorly understood. Here, we show that the expression of α-smooth muscle actin (SMA)—a cytoplasmic protein characteristic of myofibroblasts—is induced in the pleura following pneumonectomy. SMA induction appears to be dependent on pleural deformation (stretch) as induction is prevented by plombage or phrenic nerve transection (P < 0.001). Within 3 days of pneumonectomy, …
