Urea-triazone nitrogen (N) is a stable solution resulting from a controlled reaction in aqueous medium of urea, formaldehyde, and ammonia which contains at least 25% total N. This N source contains no more than 40%, nor less than 5%, of total N from unreacted urea and not less that 40% from triazone. All other N shall be derived from water-soluble dissolved reaction products of the above reactants. It is a source of slowly available N. The rate of mineralization of urea-triazone is about 66% that ...

To understand the implementation quality of the Tier 1 Program of the Project P.A.T.H.S., 25 schools and three school social service units were randomly selected to participate in telephone interviews regarding the quality of the implementation process of the Tier 1 Program of the P.A.T.H.S. Project. In the telephone interviews, the participants described the responses of the students and the workers to the program, the perceived benefits of the program, their assessment of the positive and negative ...

This paper explores the question of whether school drug testing is an effective solution to tackle adolescent substance abuse problems. Research studies in major academic databases and Internet websites are reviewed. Several observations are highlighted from the review: (1) there are few research studies in this area, particularly in different Chinese contexts; (2) the quality of the existing studies was generally low; and (3) research findings supporting the effectiveness of school drug testing were ...

The purpose of this article is to provide students and researchers entering the field of aging studies with an introduction to the evolutionary theories of aging, as well as to orient them in the abundant modern scientific literature on evolutionary gerontology. The following three major evolutionary theories of aging are discussed: 1) the theory of programmed death suggested by August Weismann, 2) the mutation accumulation theory of aging suggested by Peter Medawar, and 3) the antagonistic pleiotropy ...

337 Lake Donghu is a 32-km 2 shallow, subtropical lake near the Yangtze River (P.R. China) that has experienced dramatic changes in the past five decades. These changes include: (1) a trophic state change from mesotrophy to hypertrophy; (2) dense blooms of cyanobacteria during every summer from the 1970s to 1984; (3) a cessation of blooms starting in 1985, with no recurrence; and (4) an increase, coincident with bloom declines, in the production of silver and bighead carp (filter-feeders) by more than ...

We report the case of 36-year-old woman who had suffered from focal-unilateral right febrile grand mal since she was 9 months old as a result of neonatal asphyxia. Over the years, a modification of the clinical picture occurred and eventually the patient suffered from paranoid delusions that impaired her ability to work. After many years free from seizures, she experienced one day a generalized tonic-clonic seizure that required hospitalization and, soon thereafter, she committed suicide.

Significant uncertainty exists in magnitude and variability of ammonia (NH3) emissions, which are needed for air quality modeling of aerosols and deposition of nitrogen compounds. Approximately 85% of NH3 emissions are estimated to come from agricultural nonpoint sources. We suspect a strong seasonal pattern in NH 3 emissions; however, current NH3 emission inventories lack intra-annual variability. Annually averaged NH 3 emissions could significantly affect model-predicted concentrations and wet ...

Referral of patients to a pediatric emergency department (PED) should be medically justified and the need for referral well communicated. The objectives of this paper were (1) to create a list of criteria for referral from the community to the PED, (2) to describe how community physicians categorize their need for referral, and (3) to determine agreement between the physician's referral letter and the selected criteria. We present a descriptive study of referrals to the PED of Soroka University Medical ...

It would be an overstatement to suggest that the science of Earth’s climate system has led a sheltered life. For one thing, it has grown out of a long history of public service (e.g., weather forecasting for the public and private sectors; oceanography and marine meteorology for naval applications). For another, public interest in climatic events — ice ages, nuclear winter, El Nino, sea-level change — is sufficiently high that climate is nearly continuously in the news and has been for years. However, ...

In this study, the changes of quality characters of fenugreek according to thousand-seed weight (TSW) was examined and compared with Principal Component Analysis (PCA). Fenugreek seeds were separated into 5 different TSW ranges (W1, W2, W3, W4, W5). Different TSW had significant effects on crude protein content, palmitic, stearic, linoleic and linolenic acid contents and K, Ca and Mn contents. Linoleic acid had the highest content among fatty acid components. Increasing K and Mn contents and decreasing ...
