Development and parametric evaluation of the prototype 2 and 3 flash evaporators

Development of the Prototype 2 and 3 flash evaporator heat sinks which vaporize an expendable fluid to cool a heat transport fluid loop is reported. The units utilize Freon 21 as the heat transport fluid and water as the expendable fluid to meet the projected performance requirements of the space shuttle for both on-orbit and ascent/reentry operations. The evaporant is pulse-sprayed by on-off control onto heat transfer surfaces containing the transport fluid and exhausted to the vacuum environment through fixed area exhaust ducts

Governing Legal Embodiment: On the Limits of Self-Declaration

This article presents the first empirically-based and theoretically-informed investigation of the effectiveness of the ‘self-declaration model’ of legal gender recognition in Denmark, the first European state to adopt it. Drawing upon analysis of legislative materials, as well as interviews with stakeholders in the legislative process and trans and intersex legal subjects, it contends that self-declaration is not without its limitations. By conceptualising embodiment as an ontological and epistemological process of becoming, and emphasising the institutional dimensions and effects of such processes, it demonstrates that self-declaration may not address the complexities of legal embodiment, particularly concerning restrictions on trans and intersex people’s access to health care. The article’s empirical findings are directed towards the policymakers and activists tasked with shaping reforms of gender recognition legislation in the UK and elsewhere. The analytical agenda it develops may be adopted, and adapted, by scholars working in this area and other regulatory contexts

Mandibuloacral Dysplasia Caused by LMNA Mutations and Uniparental Disomy.

Mandibuloacral dysplasia (MAD) is a rare autosomal recessive disorder characterized by postnatal growth retardation, craniofacial anomalies, skeletal malformations, and mottled cutaneous pigmentation. Hutchinson-Gilford Progeria Syndrome (HGPS) is characterized by the clinical features of accelerated aging in childhood. Both MAD and HGPS can be caused by mutations in the LMNA gene. In this study, we describe a 2-year-old boy with overlapping features of MAD and HGPS. Mutation analysis of the LMNA gene revealed a homozygous missense change, p.M540T, while only the mother carries the mutation. Uniparental disomy (UPD) analysis for chromosome 1 showed the presence of maternal UPD. Markers in the 1q21.3-q22 region flanking the LMNA locus were isodisomic, while markers in the short arm and distal 1q region were heterodisomic. These results suggest that nondisjunction in maternal meiosis followed by loss of the paternal chromosome 1 during trisomy rescue might result in the UPD1 and homozygosity for the p.M540T mutation observed in this patient

Radiator design system computer programs

Minimum weight space radiator subsystems which can operate over heat load ranges wider than the capabilities of current subsystems are investigated according to projected trends of future long duration space vehicles. Special consideration is given to maximum heat rejection requirements of the low temperature radiators needed for environmental control systems. The set of radiator design programs that have resulted from this investigation are presented in order to provide the analyst with a capability to generate optimum weight radiator panels or sets of panels from practical design considerations, including transient performance. Modifications are also provided for existing programs to improve capability and user convenience

Credit bureaus give MFIs the ability to scale

My paper will focus on the emergence of Credit Bureaus in Latin America (Mexico specifically) due to Micro finance. It will address the importance of Credit Bureaus and how they can help Micro Finance Institutions (MFIs) become more sustainable. Microfinance is a way to lift the world out of poverty by providing financial services for low-income individuals. Microfinance institutions (MFIs) have begun to emerge all over the world in underdeveloped countries. In order for MFIs to be sustainable and have the ability to scale, they must have access to their client's credit history. The credit report allows them to make an accurate decision regarding the client's creditworthiness. They are able to charge appropriate interest rates and loan sizes based on the report. This allows the commercial banks to run successfully and make essential business decisions. The same concept applies for MFIs, yet the problem is that in many undeveloped countries in Latin America (specifically Mexico), credit bureaus are either unavailable or inaccessible to a large number of the providers. Minimal banking institutions are open to the sharing of information. The development and ownership of credit bureaus in these areas can make a significant difference in the microfinance sector. Credit bureaus can benefit the microfinance sector in many ways including diminishing risk, creating a lower transaction cost, assist in making more informed decisions, ect. Credit bureaus give MFIs the opportunity to scale and can potentially lower the poverty rate.B.A. (Bachelor of Arts
