No full textA letter to Toshiko Chuman (nee Nakamura) from Karl I. Zimmerman, District Director of Immigration and Naturalization Service (INS) in Philadelphia, and T.R. Martinez, Acting Chief, Detention, Deportation and Parole Section. The letter regards his release from INS into the custody of her attorney, Wayne M. Collins.The Chuman (Hayao "Sam" and Toshiko) Papers documents the World War II experiences of Hayao "Sam" and Toshiko Chuman, who were Kibei Nisei born in the United States but grew up and completed school in Japan, and then returned to the U.S. prior to the war. It chronicles the Chuman's incarceration from the Santa Anita Assembly Center, through Jerome, Rohwer, Tule Lake camps, and the Santa Fe and Crystal City internment camps as well as their struggle for restoring their U.S. citizenships in the 1960s. The digital collection consists of mostly textual material, including correspondence, affidavits, incarceration camp records, lease agreements, financial documents, receipts, pamphlets, and booklets

Height-diameter allometry of tropical forest trees
No full textTropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry. We have therefore developed a new global tropical forest database consisting of 39 955 concurrent H and D measurements encompassing 283 sites in 22 tropical countries. Utilising this database, our objectives were: 1. to determine if H:D relationships differ by geographic region and forest type (wet to dry forests, including zones of tension where forest and savanna overlap). 2. to ascertain if the H:D relationship is modulated by climate and/or forest structural characteristics (e.g. stand-level basal area, A). 3. to develop H:D allometric equations and evaluate biases to reduce error in future local-to-global estimates of tropical forest biomass. Annual precipitation coefficient of variation (PV), dry season length (SD), and mean annual air temperature (TA) emerged as key drivers of variation in H:D relationships at the pantropical and region scales. Vegetation structure also played a role with trees in forests of a high A being, on average, taller at any given D. After the effects of environment and forest structure are taken into account, two main regional groups can be identified. Forests in Asia, Africa and the Guyana Shield all have, on average, similar H:D relationships, but with trees in the forests of much of the Amazon Basin and tropical Australia typically being shorter at any given D than their counterparts elsewhere. The region-environment-structure model with the lowest Akaike's information criterion and lowest deviation estimated stand-level H across all plots to within amedian −2.7 to 0.9% of the true value. Some of the plot-to-plot variability in H:D relationships not accounted for by this model could be attributed to variations in soil physical conditions. Other things being equal, trees tend to be more slender in the absence of soil physical constraints, especially at smaller D. Pantropical and continental-level models provided less robust estimates of H, especially when the roles of climate and stand structure in modulating H:D allometry were not simultaneously taken into account

Carbon and nutrient accumulation in secondary forests regenerating on pastures in central Amazonia
No full textCopyright by the Ecological Society of America ©2004. Feldpausch, TR, Rondon, MA, Fernandes, ECM, Riha, SJ and Wandelli, E (2004) Carbon and nutrient accumulation in secondary forests regenerating on pastures in central Amazonia. Ecological Applications, 14 (4). S164 - S176 . ISSN 1051-0761 http://dx.doi.org/10.1890/01-6015Over the past three decades, large expanses of forest in the Amazon Basin were converted to pasture, many of which later degraded to woody fallows and were abandoned. While the majority of tropical secondary forest (SF) studies have examined post-deforestation or post-agricultural succession, we examined post-pasture forest recovery in 10 forests ranging in age from 0 to 14 years since abandonment. We measured aboveground biomass and soil nutrients to 45 cm depth and computed total site carbon (C) and nutrient stocks to gain an understanding of the dynamics of nutrient and C buildup in regenerating SF in central Amazonia.
Aboveground biomass accrual was rapid, 11.0 Mg·ha−1·yr−1, in the young SFs. Within 12–14 yr, they accumulated up to 128.1 Mg/ha of dry aboveground biomass, equivalent to 25–50% of primary forest biomass in the region. Wood nitrogen (N) and phosphorus (P) concentrations decreased with forest age. Aboveground P and calcium (Ca) stocks accumulated at a rate of 1.2 and 29.4 kg·ha−1·yr−1; extractable soil P stocks declined as forest age increased. Although soil stocks of exchangeable Ca (207.0 ± 23.7 kg/ha) and extractable P (8.3 ± 1.5 kg/ha) were low in the first 45 cm, both were rapidly translocated from soil to plant pools. Soil N stocks increased with forest age, probably due to N fixation, atmospheric deposition, and/or subsoil mining.
Total soil C storage to 45 cm depth ranged between 42 and 84 Mg/ha, with the first 15 cm storing 40–45% of the total. Total C accrual (7.04 Mg C·ha−1·yr−1) in both aboveground and soil pools was similar or higher than values reported in other studies. Tropical SFs regrowing on lightly to moderately used pasture rapidly sequester C and rebuild total nutrient capital following pasture abandonment. Translocation of some nutrients from deep soil (>45 cm depth) may be important to sustaining productivity and continuing biomass accumulation in these forests. The soil pool represents the greatest potential for long-term C gains; however, soil nutrient deficits may limit future productivity
Gender dynamics in data collection on reproductive health: field experiences in Kerala, India
No full textReproductive health researchers tend to choose interviewers of the same sex as those interviewed. In many societies, it is considered unacceptable for men to interview women on topics of an intensely personal nature like sexuality or contraceptive use. In this paper, the author analyzes 21 interviews and 16 focus group discussions (FGDs) undertaken during a field study on the Quality of Services in the Indian Family Welfare Programs conducted in Kerala. The analysis was based on the model which identifies the principal participants in the interview as the respondent and the interviewer. In all these cases the contradiction between the gendered roles of the interviewer and interviewee are visible. However, if viewed in the context of the model provided by Briggs, it is clear that these contradictions are due to the differences in the social roles that the interviewers assumed and that the respondents ascribed to them and in the interactional goals of the interviewers and the respondents. Contradictions were also experienced during the FGDs. Educational sessions on contraception are a good tool for gathering sensitive information instead of the conventional interview, where the gendered roles are so crucial to the information gathering exercise itself

Optimalisatie staalconstructies met beperkt aantal verschillende profielen
No full textHet is mogelijk om lichte en goedkope staalconstructies te ontwerpen terwijl de rekenkracht ten opzichte van bestaande methodes beperkt is. Dit volgde, na parametrisch onderzoek, uit een afstudeeronderzoek vorig jaar aan de TU Delft, bij de faculteit Civiele Techniek. Deze methode is tevens toegepast op het constructief ontwerp van een ligger zoals ontworpen door Royal HaskoningDHV. Op verzoek licht de auteur toe hoe een optimaal ontwerp, volgens een nieuwe groeperingsmethode, met een beperkt aantal verschillende profielen goed toepasbaar is.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Applied Mechanic
