Livestock Excreta

Sanitizing human excreta with nutrient recovery is a crucial issue especially for peri-urban and rural areas of developing countries. In addition to human excreta, the sanitary concerns of livestock excreta are recently growing due to control the domestic-animal-related diseases such as bird flu. In order to address those problems, this study examines the vacuum truck-collection system combined with urine-faeces diversion for peri-urban and rural areas. In the system, the diverted faeces and livestock excreta are fermented, and urine is directly used and/or phosphorus in urine is recovered by struvite formation. Firstly, each treatment and recovery is examined from the technological aspects. Secondly, the methane and struvite production in the system is calculated. As a result, the fermentation was considered to proceeds easily compared to traditional mixed excreta fermentations, and nutrient in urine could be easily recovered in the system. In addition, the system produces methane of 1,107 Nm3-CH4 per day, struvite of 51.9 ton-P2O5 per year for a population of 100,000 with 5,000 pigs and 20,000 chickens.

Most industrial and academic geologists are familiar with the beautiful red and orange cathodoluminescence colours produced by carbonate minerals in an optical microscope with a cold cathode electron gun attached. The cement stratigraphies interpreted from colour photographs have been widely used to determine the post depositional processes which have modified sedimentary rock textures.However to study quartzose materials high electron densities and kV's are necessary to stimulate sufficient emission. A scanning electron microscope with an optical collection system and monochromator provides an adequate tool and gives the advantage of providing secondary and backscattered electron imaging as well as elemental analysis and distribution mapping via standard EDS/WDS facilities.It has been known that the incorporation of many elements modify the characteristics of the CL emissions from geological materials. They do this by taking up positions between the valence and conduction band thus providing sites to assist in the recombination of electron hole pairs.

A free text data collection system has been developed at the University of Illinois utilizing single word, syntax free dictionary lookup to process data for retrieval. The source document for the system is the Surgical Pathology Request and Report form. To date 12,653 documents have been entered into the system.The free text data was used to create an IRS (Information Retrieval System) database. A program to interrogate this database has been developed to numerically coded operative procedures. A total of 16,519 procedures records were generated. One and nine tenths percent of the procedures could not be fitted into any procedures category; 6.1% could not be specifically coded, while 92% were coded into specific categories. A system of PL/1 programs has been developed to facilitate manual editing of these records, which can be performed in a reasonable length of time (1 week). This manual check reveals that these 92% were coded with precision = 0.931 and recall = 0.924. Correction of the readily correctable errors could improve these figures to precision = 0.977 and recall = 0.987. Syntax errors were relatively unimportant in the overall coding process, but did introduce significant error in some categories, such as when right-left-bilateral distinction was attempted.The coded file that has been constructed will be used as an input file to a gynecological disease/PAP smear correlation system. The outputs of this system will include retrospective information on the natural history of selected diseases and a patient log providing information to the clinician on patient follow-up.Thus a free text data collection system can be utilized to produce numerically coded files of reasonable accuracy. Further, these files can be used as a source of useful information both for the clinician and for the medical researcher.
