Regional Inequality, Poverty and Economic Integration in Brazil. [PDF]

open access: yes
Gains and losses from trade liberalization are often unevenly distributed inside a country. For example, if budget shares vary according to household income, changes in commodity prices will redistribute an overall welfare change between household types.

Pathogenesis and Causes of Premature Ovarian Failure: An Update [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2011
Premature ovarian failure (POF) affects 1% of young women. This condition has significant psychological sequelae and major health implications. POF seriously interferes with fertility and family planning. Diverse etiologies are associated with POF.

Smart technical textiles with integrated POF sensors

open access: yes, 2008
Fiber optic sensors based on polymer optical fibers (POF) take advantage of the high elasticity and high break-down strain of POF. Because of their outstanding elastic properties, POF are well suited for integration into technical textiles like ...

Low-cost WDM QAM transmission of 100 Mbit/s over 150 m step-index 1 mm core diameter PMMA polymer optical fiber

open access: yes, 2008
Since the bandwidth of large-core step-index (SI) polymer optical fiber (POF) is quite limited, Quadrature Amplitude Modulation (QAM) is considered to increase the channel capacity.

The effects of probiotics, prebiotics, and synbiotics on aversive memory in a premature ovarian failure model in rat

open access: yesPhysiological Reports
Cognitive impairment occurs in cisplatin‐induced premature ovarian failure (POF). The impacts of probiotics, prebiotics, and synbiotics on passive avoidance memory, oxidative stress markers, and acetylcholinesterase (AChE) activity in the POF model were ...

Gigabit Ethernet over standard step-index polymer optical fiber

open access: yes, 2008
The use of standard 1-mm core-diameter stepindex plastic optical fibre (SI-POF) has so far been mainly limited to distances of up to 100 meters and low bit-rates in the order of 125 Mbit/s. By use of digital signal processing, transmission performance of
