ABSTRACTIncreased concern by the State of South Carolina over the condition and capacity of the low-level radioactive waste burial site at Barnwell has prompted them to promulgate new regulations on waste burial containers. As of September 30, 1981, ion exchange resin and filter media waste with an activity of 1 μCi/cc or greater and with isotopes with halflives greater than five years disposed at Barnwell shall be solidified or confined in a “high integrity container”. The materials and designs of these containers are required to provide waste isolation from the environment for a period of 300 years and provide the structural integrity specified in 49 CFR 173.398(b). HITTMAN has been active in the design and development of containers suitable for this purpose with this paper detailing the analyses involved. Material selections were limited to stainless steel, fiberglass, and polyethylenes. Structural concerns focused on overpressure requirements, drop-testing requirements, and lifting capabilities. With a lifetime dose of up to 108 rads, the possibilities of radiation damage were considered. Preliminary selection of polyethylene was based on satisfactory resolution of these issues and economic factors.

Shell repairs resulting from presumed failed predation are documented in gastropods from the Late Ordovician (Cincinnatian; Richmondian) mid-to-upper Kagawong Submember of the Georgian Bay Formation on Manitoulin Island, Ontario, Canada. The bryozoan–mollusc biota and associated sediments generally suggest nearshore, shallow (<10 m), low energy (lagoonal), and perhaps mesotrophic to eutrophic conditions. Two sample sets from this unit have been studied for shell repair. One of the more commonly applied estimates of shell repair frequencies involves division of the number of individuals with at least one scar by the total number of individuals in the sample (the Individuals with scars method). Using this calculation, 207 specimens of Lophospira trilineata Ulrich and Scofield yielded a shell repair frequency of 4.8%; in 28 specimens of Trochonemella sp. the shell repair frequency was 35.7%. Repairs in Trochonemella occur primarily in the larger size class, suggesting that a size refuge was achieved by this species. Low repair frequencies in L. trilineata suggest predation with a higher success rate or fewer encounters. This study demonstrates that the paradigm of a standardized low level of shell repair in Ordovician and Silurian gastropods is oversimplistic and a range of frequency rates can be expected.

A technique for evaluating preference for television (TV) programs provided six low-level and six high-level retardates with a simultaneous choice of four keys, each programing a different consequence. The total time S depressed each of the four keys resulting in three different TV programs or no program (no audio or video) was recorded. Each consequence was continuously available and the consequence programmed by each key was switched every 2 min. All Ss spent most of the session responding for TV and preferred TV over no consequence. Five low-level and one high-level S showed a preference for a single program. The preference of one low-level and two high-level Ss varied from day to day and that of three high-level Ss changed one or more times during 10 sessions. One program can be repeated many times with low-level retardates before satiation occurs; whereas satiation occurs quickly with high-level retardates. TV preference might well be considered as a technique for selection of reinforcers. The technique has much to offer to those concerned with developing educational programs.

The random amplified polymorphic DNA (RAPD) technique was used to evaluate both genetic diversity among 19&nbsp;soybean accessions included in the Czech National Collection of Soybean Genotypes and their potential as a new source of genetic variations for soybean breeding programs. Only 22 of all the 40 random primers used in RAPD reactions showed polymorphism acceptable for an effective characterisation of these accessions. Altogether 122 highly reproducible RAPD fragments were generated, 55 of them were polymorphic (46%). However, because of the previously observed low degree of RAPD polymorphism in the case of Glycine max, fragments with low level of informativeness were evaluated, too. Presented results enable the selection of genetically distinct individuals. Such information may be useful to breeders willing to use genetically diverse introductions in soybean improvement process.&nbsp;

AbstractTwo field-collected strains of Culex quinquefasciatus Say, collected 50 km apart in Havana City, Cuba, were both resistant to malathion and propoxur, while one population also showed low level resistance to temephos. Laboratory selection of the latter population with malathion for 22 generations increased the malathion resistance 1050-fold, temephos resistance 24-fold and propoxur resistance 453-fold compared to the standard laboratory susceptible strain. Synergist studies and biochemical tests indicated that two mechanisms, an elevated esterase and an insensitive acetylcholinesterase, were operative in these strains. The esterase mechanism conferred resistance to malathion, but not to temephos or propoxur. The acetylcholinesterase mechanism increased the level of malathion resistance and extended the cross-resistance spectrum to temephos and propoxur.

Adoption was a process of behavior change either in the form of knowledge, attitudes  and  skills  in  a  person  in  accepting  innovation  delivered  by  farming educator.The  research  objective  was  to  determine  the  level  of  Inpara  adoption   in swampyland with information output of Inpara adoption varieties in swampylands.The research  was  conducted  in  swampyland  on  Tapin  and  Hulu  Sungai  Utara  (HSU) district  during  February  to  May  2015.Total  sample  of  60  people  selected  randomly distributed in the six villages.  Data were analyzed descriptively both qualitative and quantitative  data  with  scoring  techniques.Results  showed  that  the  level  of  Inpara adoption  on  swampyland  remained  low,  i.e.  66.88%/year  on  HSU  district  and  (-74.56%/year) on Tapin district.The low level of adoption was due to the selection of varieties  that  had  been  developed  in  swampland,  namely  Ciherang,  Mekongga  and some  numbers  Inpari  adaptive  and  dissemination  of  varieties  Inpara  not  widely distributed to  swampyland  area.Despite the level of knowledge of  farmers on Inpara varieties was relatively high (68.3%) and attitudes of farmers toward Inpara varieties innovation  were  classified  agree  (72.9%),  not  yet  ensure  increased  adoption  of Inpara varieties in the two districts.

Relevance. The level of the patient adherence significantly influences the effectiveness of the treatment. Aim – to determine the level of adherence to the doctor’s recommendations and prescriptions in periodontal patients. Materials and methods. 360 periodontal patients of both sexes and different ages filled in a questionnaire to quantitatively assess the treatment adherence, outlined in 1st Russian consensus on the quantitative assessment of the treatment adherence, 2017. The adherence to the therapy, medical management, life style changes and the overall treatment adherence were determined. Results. The low level of the overall treatment adherence was revealed in 36% of the questioned subjects. The adherence to the life style changes was significantly low in almost all patient groups, thus, determining the low level of adherence to treatment. Only patients over 60 showed a higher adherence to all doctor’s recommendations. Male patients demonstrated a lower level of the overall adherence as well as adherence parameters separately. Conclusion. The adherence evaluation allows customizing the approach to the selection of the recommendations and treatment schemes according to a patient adherence level as well as determining possible ways of adjustment of the motivation level.

Categories reduce the complexity of the environment, are the means by which objects are identified, reduce the need for constant learning, allow for the selection of an appropriate action, and support the organization of objects and events. The most typical members of categories share attributes with the other members of the category. Prototypes are the central members. Hierarchies are composed of subordinate (desk lamp), basic (lamp), and superordinate (furniture) categories. Social categories such as “ baby boomers” classify people but may be associated with misleading stereotypes. Action categories include event boundaries that mark the transition between actions. They are organized into low-level (elbow angle) and high-level (pouring milk) actions.
