*Prepared in the Program Division, B u reau of Employment Security. D U R I N G 1946, employers subject to State unemployment insurance laws were taxed at an estimated average rate of 1.4 percent of taxable pay rolls (table l ) 1 —the lowest average rate since the first year of the program (1936) when the Federal tax rate was only 1 percent. The 1.4percent revenue rate is expected to yield $828...

The restriction of Pipe, a potential glycosaminoglycan-modifying enzyme, to ventral follicle cells of the egg chamber is essential for dorsoventral axis formation in the Drosophila embryo. pipe repression depends on the TGFalpha-like ligand Gurken, which activates the Drosophila EGF receptor in dorsal follicle cells. An analysis of Raf mutant clones shows that EGF signalling is required cell-au...

Natural rubber (cis-1,4-polyisoprene) is an isoprenoid compound produced exclusively in plants by the action of rubber transferase. Despite a keen interest in revealing the mechanisms of rubber chain elongation and chain length determination, the molecular nature of rubber transferase has not yet been identified. A recent report has revealed that a 24 kDa protein tightly associated with the sma...

Rubber is the most widespread smallholder tree crop in South-East Asia. Although initially large estates planted the bulk of the region’s rubber, smallholders soon captured most of the production. Currently, Indonesia’s rubber plantations cover 3.4 million ha, of which smallholders account for more than 75% (BPS, 1999). In peninsular Malaysia, the area in rubber has declined since the 1970s, bu...

Several literatures presented automated systems for detecting or classifying sewer pipe defects based on morphological features of pipe defects. In those automated systems, however, the morphologies of the darker center or some uncertain objects on CCTV images are also segmented and become noises while morphology-based pipe defect segmentation is implemented. In this paper, the morphology-based...

CRA-lined pipelines, i.e. pipes with an inner pipe of a corrosion resistant alloy inside of a ferritic steel pipe carrying the hoop stress, pose a challenge to inspect with conventional in-line inspection technologies. Existing UT technology is not able to inspect through the interface of a CRA and a ferritic steel component. Additionally, current MFL technology is not able to sufficiently magn...

Rubber dams are inflatable and deflatable hydraulic structures. Thousands of rubber dams have been installed worldwide for various purposes: irrigation, water supply, power generation, tidal barrier, flood control, environmental improvement, and recreation. Furthermore, rubber dams have been used in cold areas where the temperature is as low as –40°C. The simplicity and flexibility of the rubbe...

To evolve structured programs we introduce H-PIPE, a hierarchical extension of Probabilistic Incremental Program Evolution (PIPE). Structure is induced by \hierarchi-cal instructions" (HIs) limited to top-level, structuring program parts. \Skip nodes" (SNs) allow for switching program parts on and oo. They facilitate synthesis of certain structured programs. In our experiments H-PIPE outperform...

an important issue in power generation and petrochemical industries is the monitoring of pipe wall thickness and corrosion/erosion rate. the pipes are usually subject to erosive and/or corrosive environments and any failure could be catastrophic. while periodic manual ultrasonic thickness measurement is the common practice in many industries, in certain cases, where higher accuracies are requir...
