    The Project Advisory Group was established in 1967 as an advisory group to the Office of Legal Services (OLS) of the OEO. PAG served as the voice of legal services organizations, lawyers, paralegals, staff and clients. The original members were hand-picked by the OLS and consisted primarily of project directors. By the early 1990s, almost all federally funded legal services programs were members of PAG. Funding for PAG grew increasingly problematic, and in 1998, PAG merged with the National Legal Aid and Defender Association (NLADA).The PAG Report was published beginning in 1978

    Psych-Aetiology Graph (PAG)

    This paper will introduce the ‘Psych-Aetiology Graph’, PAG for short. The concept of PAG is devised by the author as a way of conceptualising/formalising/summarising the client’s condition. The term ‘Psych-Aetiology’ is used to encompass all the Bio-Psycho-Social factors contributing to the client’s presenting condition. Also, the graph has no arithmetic value and is not based on any particular measurements or calculations. The target of the PAG is the client. Its main aim (amongst many) is to educate and give the client an understanding of factors resulting or contributing to their state. It is subjective, whereby the client and the therapist must cooperate in its formation

    The Effect of Inner Grooved Tubes on the Heat Transfer Performace of Air-Cooled Heat Exchangers of Co2 Heat Pump System

    In the CO2 heat pump system, Poly alkyl glycol (PAG) oil is commonly used for lubrication of the compressor, while it is reported that the PAG oil has influence on the heat transfer performance due to its immiscibility against CO2 within its working condition. Experimental work has been carried out to investigate the heat transfer performance of fin and tube heat exchangers using CO2 as a refrigerant with taking PAG oil into account. From previous study it was found that the heat transfer performance decreased significantly in both evaporator and gascooler conditions when oil was mixed. The present work presents experimental results on three types of air-cooled heat exchangers with smooth and inner grooved tubes. It was found that the deterioration ratio of heat transfer performance with oil was different depending on the inner surface geometry of the grooved tubes. To understand this, flow visualization inside these tubes has also been carried out through transparent section made of glass, which can withstand high pressure. It was confirmed that the oil behavior inside tubes was related to heat transfer performance. Heat transfer performance can be improved by using inner grooved tubes with the optimal pattern to remove oil away from inner surface. These tubes are effective to develop high performance heat exchangers for the CO2 heat pump system
