The Galveston Bay beach is a widely used recreational area that remains a concern in terms of water quality. There are many factors that contribute to its pollution such as fecal matter entering the bay due to overflow of the sewage system and run offs. Thus, evaluating the water quality for fecal matter and other pollutants is continuously monitored by citizen scientists and research groups throughout the Galveston Bay. The investigation utilizes the colorimetric response of coliform at three test sites along the East Bay of Galveston. Each response is positive for coliform that may indicate the presence of fecal matter. Other scientists have denoted the presence of fecal matter in the Galveston Bay at two sites using enterococci indicator which may be more associated with human fecal matter. The analyses show that the recreational water is likely not a threat since its levels were low. However, the need for analyses based on EPA protocols and standards is necessary to better access water pollution due to fecal matter in the Galveston Bay area.

作者： Jeffery M. Plumblee Lansford bell Leidy ]E. Klotz Department of Civil Engineering Clemson University Clemson SC 29634 USA

The civil engineering profession, in an adaptive reaction to emerging roles for civil engineers, is recognizing the need for new engineers to possess a more robust skill set than just the typical design background. This paper describes the efforts of Clemson Engineers for Developing Countries （CEDC） to fulfill the more nontraditional and often unaddressed ＂learning outcomes＂ noted by ASCE＇s Civil Engineering Body of Knowledge lbr the 21st Century as important prerequisites for licensure. The learning outcomes are addressed through ongoing international service learning projects in Cange, Haiti. The paper focuses on the following four outcomes and their fulfillment methods： leadership, globalization, teamwork, and communications. The student led organization has allowed students to set up their own fundraising mechanisms, to seek out members to join design review boards, and to develop their own project objectives. This level of student autonomy is n,3ted as key to ensuring that students achieve competency in these four areas.

In rainfed lowlands, the beneficial effects on rice (Oryza sativa) yield from fertilizing the seedling nursery may depend on the occurrence of water and nutrient stress after transplanting into the mainfield. The aim of the study was to test the effect of seedling age and nursery fertilisation on rice yield when plants experienced nutrient and water stress regimes after transplanting. The first experiment, conducted during the wet season in a low-fertility rainfed lowland field in south-east Cambodia, examined the effect of three levels of nitrogen (N), phosphorus (P) and cow manure (CM) application to the nursery and three ages of seedlings at transplanting (4, 6 and 9 weeks after sowing: WAS) on the growth of a traditional photoperiod-sensitive rice cultivar. Increasing fertilizer application to the nursery increased shoot dry weight and grain yield at each age of seedling transplanted. Shoot dry weight and grain yield from seedlings transplanted 6 WAS were 20% and 10% higher than those from the seedlings transplanted at the other ages. Seedlings transplanted at 4 WAS, which experienced a temporary submergence for 3 days after transplanting, recorded 5% greater seedling mortality from the unfertilized than fertilized nursery soil. The taller seedlings transplanted at 6 WAS experienced less mortality despite more severe submergence. The second experiment was conducted at seven rainfed lowland sites across Cambodia to test the benefit of N alone and N+P application to the nursery on rice yields in farmers’ fields. In four out of seven trials, grain yield increases averaged 13% with N+P applied to the nursery whereas N alone increased grain yield at two sites and depressed yield at two. Overall, fertilizer application in the nursery produced more vigorous seedlings with higher nutrient concentration which survived submergence and grew better with or without drought or nutrient stress after transplanting, leading to increased yields of rice.

The work presented in this article focuses on document forgery. Document fraud is a generic term used to designate a fraud, a falsification of a document. The said falsification can be observed in several sectors of everyday life. For a better illustration, let’s consider a system for producing civil status forms. The birth certificate is generally the basis of any individual’s life, and if this document is falsified, it can have repercussions at several levels, particularly in the academic field, where false diplomas, false national identity cards, false passports, false marriage certificates, etc. are obtained. It is therefore demonstrated that a secure production unit for civil status forms can be beneficial to both developed and developing countries. In addition, smart contract is proposed using a private Hyperledger fabric blockchain for validation of civil status documents, and a non-state public key management infrastructure is also proposed to authenticate the nodes that will validate the transactions. This improved blockchain solves the problem of falsification of civil status documents, as false nodes can contribute to the validation of a transaction. The contribution of such a hybrid system is of paramount importance for the identity of civil status documents on the one hand and for the identity of documents in general, and the blockchain to guarantee the distributed, unforgeable, non-repudiation, transparency and disintermediation character.

Two thirds were randomized to active care (6 mo colonoscopy and drug intensification for endoscopic recurrence) and one third to drug therapy without early endoscopy. Colonoscopy at 18 mo and faecal calprotectin (FC) measurement were used to assess disease recurrence. Administrative data, chart review and patient questionnaires were collected prospectively over 18 ***: Sixty patients (active care n = 43, standard care n = 17) were included from one health service. Median total health care cost was $6440 per patient. Active care cost $4824 more than standard care over 18 mo. Medication accounted for 78% of total cost, of which 90% was for adalimumab. Median health care cost was higher for those with endoscopic recurrence compared to those in remission [$26347 (IQR 25045-27485) vs $2729 (IQR 1182-5215), P < 0.001]. FC to select patients for colonoscopy could reduce cost by $1010 per patient over 18 mo. Active care was associated with 18% decreased endoscopic recurrence, costing $861 for each recurrence ***: Post-operative management strategies are associated with high cost, primarily medication related. Calprotectin use reduces costs. The long term cost-benefit of these strategies remains to be evaluated.
