The significant expansion in the use of nanoparticles and submicron particles during the last 20 years has led to increasing concern about their potential toxicity to humans and particularly their impact on male fertility. Currently, an insufficient number of studies have focused on the testicular biodistribution of particles. The aim of our study was to assess the distribution of 450 nm fluore...

When firms collude and charge supracompetitive prices, consumers can bring antitrust lawsuits against the firms. litigation cost is low, accept as just another of doing business, whereas when high, lower price to deter litigation. Class action modeled a mechanism that allows plaintiffs attorneys obtain economies scale. We show class actions, firms’ incentive block them, may or not be socially d...

Firm-level, revenue-based productivity measures are ubiquitous in studies of firm dynamics and aggregate outcomes. One common measure is increasingly interpreted as reflecting “distortions” since distortions’ absence, equalization marginal revenue products should yield no dispersion this measure. Another but distinct the residual firm-level function, which reflects “fundamentals.” Using micro-l...

We use time series techniques to estimate the importance of four main explanations for decline US labor income share: rising firm markups, falling bargaining power workers, higher investment-specific technology growth, and more automated production processes. Identification is achieved with restrictions derived from a stylized model structural change. Our results point automation as driver shar...

The diversity of plant life forms in tropical forests affords the opportunity for assembly of plant combinations, both natural and managed, that make full use of resources and sustain high productivity. The influence of combining life forms on productivity and resource use was evaluated using three fast-growing tree species (Hyeronima alchorneoides, Cedrela odorata, and Cordia alliodora); each ...

Mutual diffusion coefficients of chloroquine diphosphate (CDP) in aqueous solutions both without and with ?-cyclodextrin (?-CD) were measured at concentrations from (0.0000 to 0.0100) mol dm?3 298.15 K, using the Taylor dispersion technique. Ternary mutual (Dik) by same technique are reported for CDP + ?-CD K. The presence ? CD led relevant changes process, as showed nonzero values cross-diffus...

The common practice of artificially rearing lambs from prolific meat breeds sheep constitutes a welfare issue due to increased mortality rates and negative health issues. In this multidisciplinary study, we investigated the possible short- mid-term advantages feeding fresh ewe's milk instead commercial replacer on lambs' growth, welfare. Romane were either separated their mothers D3 fed with La...
