Project management in Apollo progra
Manned space flight in transition
A study was conducted to analyze the reorientation of NASA programs in the post-Apollo period. The study is an external view of NASA by unbiased observers as an input to and aid in the decision making process concerning near and long term planning. The subjects discussed are: (1) the near-term NASA scenario; (2) organization of field centers; (3) planning activities; and (4) operational activities. A summary of the recommendations arising as a result of the study is presented
Economics of animal genetic resources use and conservation
Economic analysis can play an important role in the sustainable management of animal genetic resources (AnGR). The first report on The State of the World’s Animal Genetic Resources for Food and Agriculture (first SoW-AnGR) (FAO, 2007a) included a section on methods for economic evaluation 1 that provided an overview of the various types of value that can be distinguished (direct and indirect use values, option values, bequest values and existence values) and described potential methods and tools for assessing them. It also presented some examples of the use of these methods and tools and the findings obtained. This updated section provides an overview of recent developments in the economics of AnGR use and conservation. The revised title reflects the way in which this field of work has moved beyond just the development and testing of methods

Model of Enterpreneurship and Social-cultural and Market Orientation of Small Business Owners in Poland
In the development of SMEs in Poland crucial meaning is legislation, steadily adapted to EU regulations, especially to the European Charter for Small Enterprises. Research conducted in Poland by many authors provide data for doing so, to confirm the hypothesis that among small businesses a vital role in shaping their work situation did not continue to play the market mechanisms and orientations, but mainly socio-cultural factors.W rozwoju MŚP w Polsce podstawowe znaczenie mają również uregulowania prawne, systematycznie dostosowywane do regulacji unijnych, zwłaszcza zaś do Europejskiej Karty Małych Przedsiębiorstw. Badania prowadzone w Polsce przez wielu autorów dostarczają danych ku temu, by potwierdzić tezę, że wśród drobnych przedsiębiorców decydującą rolę w kształtowaniu ich sytuacji pracy odgrywają nadal nie mechanizmy i orientacje rynkowe, ale przede wszystkim czynniki społeczno-kulturowe
Virilization and abdominal mass in a newborn female: A case report
We describe virilization in a newborn female secondary to bilateral congenital juvenile granulosa cell tumor (JGCT). The patient presented with abdominal mass and ambiguous genitalia at birth, and bilateral ovarian masses were discovered on further imaging. The patient underwent bilateral salpingo-oophorectomy in staged procedures, as it became apparent that we could not spare the ovaries. Diagnosis of JGCT was confirmed by surgical pathology. She required no adjuvant therapy and has no signs of recurrence at two-year follow-up
Preventing Chlorogenic Acid Quinone-Induced Greening in Sunflower Cookies by Chlorogenic Acid Esterase and Thiol-based Dough Conditioners
Sunflower seeds contain a high concentration of chlorogenic acid (CGA), which reacts with amino acids to form green pigments under alkaline conditions during food processing. Here, we present two approaches to prevent green pigment formation in sunflower cookies by (A) Addition of free thiols from cysteine and glutathione to sunflower cookie dough and (B) hydrolyzing CGA into caffeic acid and quinic acid with a CGA esterase from Lactobacillus helveticus. Greening occurred more slowly with cysteine; however, neither cysteine nor glutathione prevented greening in the cookies during storage. Chlorogenic acid esterase hydrolyzed CGA in both sunflower butter and flour, resulting in the complete elimination of greening in the sunflower cookies. CGA esterase treatment was efficient as the enzyme could be applied in low amounts (\u3c100 ppm) directly to the dough without needing to pretreat either sunflower butter or flour. Overall, our data indicate that CGA esterase treatment was an effective method of eliminating unwanted greening in sunflower cookies made with baking soda. Long term, these results may represent a method of increasing the use of sunflower butter and flour in high pH baking applications by enabling their use in neutrally colored baked products such as cookies and muffins
Domestication of payments for ecosystem services: new evidence from the Andes.
The current project has sought to assess i) the potential of agricultural biodiversity-focused PES to serve as a cost-effective and socially equitable domesticated diversity conservation incentive scheme, as well as ii) how economic incentive mechanisms such as PES can be designed to build on and complement local institutions of collective action. Results are presented from pilot Payment for Agrobiodiversity Conservation (PACS) schemes and framed field experiments implemented in the Bolivian and Peruvian Andes aimed at sustaining diversity within quinoa, a traditional Andean grain.
Findings indicate that opportunity costs of conservation vary widely not only between the two study sites, but also between community-based groups within each site. This creates opportunities to minimize intervention costs by selecting least-cost conserving farmers. However, as shown with respect to the role of wealth and cooperation in determining opportunity costs, this also has implications for the type of farmer to be included in the conservation programme. Promisingly, depending on the fairness principle deemed most important in the local context, there does not necessarily have to be a significant trade-off between the schemes’ potential cost-effectiveness and equity outcomes. The observed behavior in the farmer experimental games further supports such findings and suggests that understanding farmer perceptions of fairness can have important implications for the design of conservation incentive mechanisms, particularly given the important influence of such perceptions on the pro-social behavior that underlies much de facto conservation. Incentive mechanisms, such as PACS, that can support socially valued ends not only by harnessing selfish preferences to public ends but also by evoking public-spirited motives are also more likely to be sustainable over the long-term.
The use of PACS incentives for the maintenance of traditional crop varieties and the improvement of smallholder farmer livelihoods thus appears promising for further development and up-scaling
TSH-CHECK-1 test: diagnostic accuracy and potential application to initiating treatment for hypothyroidism in patients on anti-tuberculosis drugs.
Thyroid-stimulating hormone (TSH) promotes expression of thyroid hormones which are essential for metabolism, growth, and development. Second-line drugs to treat tuberculosis (TB) can cause hypothyroidism by suppressing thyroid hormone synthesis. Therefore, TSH levels are routinely measured in TB patients receiving second-line drugs, and thyroxin treatment is initiated where indicated. However, standard TSH tests are technically demanding for many low-resource settings where TB is prevalent; a simple and inexpensive test is urgently needed
