Blighia Sapida

This research evaluated and determined some moisture-influenced physical and gravimetric properties of Blighia sapida seeds relevant to machine design at 11.9, 17.0, 22.0, 27.0 and 32.0% moisture levels (wet basis). These properties are vital in handling and seed process design. With increasing seed moisture (11.9 to 32.0%), there was no statistically significant effect on the seed axial dimensions, principal diameters, sphericity and surface area. This is because seed axial dimensions relatively determine other properties afore stated. However, there were significant and linear increases in thousand seed mass (189.3 – 230.3 g), bulk (377.0 - 418.3 kg m-3) and true (714.3 - 771.1 kg m-3) densities but decrease in porosity was not significant. Increase in bulk and true densities is due to the rate of increase in the seed mass being more rapid than the rate of increase in its volume, as the seed moisture increased. A non-linear decrease showed in seed volume (3.4-3.2 cm3). Behavioral patterns of ackee seeds and their investigated properties, under increasing moisture was expressed using regression models. Required primary data for the design of handling techniques and process machinery for ackee apple seeds were generated.

Blighia Sapida

The friction properties of ackee apple (Blighia sapida) seeds at an 11.9, 17, 22, 27, and 32% (w.b.) seed moisture were determined, which are vital for designing their processing techniques and equipment to replace the present manual methods. The ackee apple grows in many West African countries, especially Nigeria. The ackee seeds were harvested at Lanlate, Oyo State, Nigeria, where ackee trees are predominant. Standard experimental methods were adopted to determine the properties. The data were analysed using an ANOVA and the least significant difference (LSD) at P ≤ 0.05. As the moisture increased, the static coefficient of friction on glass (27.6–36.40), aluminium (27.0–30.2), polyvinyl chloride (PVC; 27.9–32.8) surfaces and normal stress at 200 g (8.73–8.93 g×cm–2), 300 g (11.65–11.79 g×cm<sup>–2</sup>) and 400 g (14.37–14.65) loads increased significantly and linearly. The shear stress linearly decreased at a 200 g load (1.62–1.25 g×cm<sup>–2</sup>), but was non-significant at the 300 and 400 g loads. The coefficient of internal friction linearly decreased (0.744–0.588) implying that the wet seeds flow more easily than the dry ones, which should be considered in designing conveyors. The relationships between the ackee seeds' moisture and friction properties were expressed with regression models. Data for designing the handling techniques and machines for the ackee seeds were obtained.

The changes in information technology have also changed community behavior in doing transaction payments from cash to non-cash. This study aims to discover the effect of easiness, trust, life-style, and risk factors on people of Yogyakarta city interest to do a non-cash transaction. The research data were primary data obtained through interviews and questionnaires to 100 respondents in Malioboro shopping center which is the icon of Yogyakarta city, Indonesia. The data then estimated through multiple linear regression models using SPSS 16 statistical program. The result of the study empirically showed that easiness, trust, and life-style had positive and significant effects on the community’s choice to have non-cash transactions. Meanwhile, risk had a negative and significant effect on the interest of people in doing non-cash transactions. In general, non-cash payment promoted the intensity and capacity of a payment transaction because the payment is easier and cheaper. This study recommends increasing community awareness about the benefits and risks of a non-cash payment transaction. Moreover, law enforcement of customer protection from the misuse of non-cash payment facilities should be enhanced.

Despite its importance for forest regeneration, food webs, and human economies, changes in tree fecundity with tree size and age remain largely unknown. The allometric increase with tree diameter assumed in ecological models would substantially overestimate seed contributions from large trees if fecundity eventually declines with size. Current estimates are dominated by overrepresentation of small trees in regression models. We combined global fecundity data, including a substantial representation of large trees. We compared size–fecundity relationships against traditional allometric scaling with diameter and two models based on crown architecture. All allometric models fail to describe the declining rate of increase in fecundity with diameter found for 80% of 597 species in our analysis. The strong evidence of declining fecundity, beyond what can be explained by crown architectural change, is consistent with physiological decline. A downward revision of projected fecundity of large trees can improve the next generation of forest dynamic models.

In this study, we addressed the need for empirical research on human trafficking by compiling unique data relating to criminal charges filed in federal judicial districts and using these data to examine trends in sex trafficking-related cases, as well as the impact on those trends of the Trafficking Victims Protection Act of 2000 (TVPA). Results from our regression models indicate that the proportion of all charges filed by federal prosecutors that involved sex trafficking and related cases increased significantly between 1994 and 2007. The rate of increase, however, slowed in the time period following the passage of the TVPA, suggesting that the TVPA may have helped to mitigate increases in new cases. In addition, our results show statistically significant inverse relationships between immigration and sex trafficking-related charges filed, providing new evidence to support the possibility that some sex trafficking-related cases may be being prosecuted as immigration cases instead.

In the hot and dry conditions in which seeds of the tree legume Peltophorum pterocarpum develop and mature in Vietnam, seed moisture content declined rapidly on the mother plant from 87% at 42 d after flowering (DAF) to 15% at 70 DAF. Dry weight of the pods attained a maximum value at about 42 DAF, but seed mass maturity (i.e. the end of the seed-filling phase) occurred at about 62 DAF, at which time seed moisture content was about 45–48%. The onset of the ability of freshly collected seeds to germinate (in 63-d tests at 28–34°C) occurred at 42 DAF, i.e. about 20 d before mass maturity. Full germination (98%) was attained at 70 DAF, i.e. at about 8 d after mass maturity. Thereafter, germination of fresh seeds declined, due to the imposition of a hard seed coat. Tolerance of desiccation to 10% moisture content was first detected at 56 DAF and was complete within the seed population by 84 DAF, i.e. about 22 d after mass maturity. Hardseededness began to be induced when seeds were dried to about 15% moisture content and below, with a negative logarithmic relation between hardseededness and moisture content below this value.
