A wood budget was constructed for the Game Creek basin (132 km2) in southeast Alaska to identify spatial and temporal controls on abundance distribution of large woody debris (LWD). Field measurements storage, size, age were used estimate volumetric rates LWD recruitment transport. Mortality did not follow a pattern ranged from 0.1 8.1 m3·km−1·year−1 (recruitment corresponded forest mortality 0.1–2.6% per year). Wood by bank erosion increased with increasing drainage area 1 at smallest areas...

Large woody debris (LWD) and channel data from three Alaska coastal regions with varying geomorphic types were analyzed to document regional variability in LWD abundance, define characteristics affecting identify relationships between abundance the formation of pools gravel bars streams. was significantly lower at northern edge coniferous forest than Southeast greater alluvial gravel-bedded channels contained boulder–bedrock channels. More formed by Pool spacing (the number widths pools)...

The 1980 eruption of Mount St. Helens impacted salmon streams on the west side mountain primarily by debris and mud deposits; depositions ash large wood were relatively minor disturbances. We examined factors related to juvenile coho (Oncorhynchus kisutch) disappearance during summer winter months 1981 1982. Correlations exist between survival anadromous fish, instream vegetative cover, water temperature. Summer mortality was high stream temperatures lack organic debris. Recovery riparian...

We compared the stand conditions in buffer strips with those unlogged riparian stands similar site characteristics using large-scale aerial photography to deduce differences mortality and large woody debris (LWD) recruitment. found cumulative (CSM) was significantly greater units reference that varied distance from stream. In inner zone (0–10 m stream), mean difference CSM between relatively small (22% of CSM), but outer (10–20 stream) more than double (120%) units. The is primarily result a...

Abstract Logging regulations in the Pacific Northwest and Alaska have evolved over time to alleviate negative effects that historic harvest practices had on stream habitat. While natural landscape factors largely control habitat, timber can alter these influences, underscoring importance of clarifying both for understanding managing habitat streams. We sampled areas Southeast riparian zones harvested between 1980 1990, a period less‐restrictive regulations. Relationships geomorphic with...

Abstract We evaluated trends in fish habitat condition and their relationship to natural management‐associated disturbances forests of coastal Southeast Alaska. Monitoring data spanning 9–19 years (1994–2012) from 14 stream reaches were examined using linear mixed‐effects models evaluate patterns condition. Modeling detected multiple change that included postharvest pulses large wood (LW) recruitment reductions substrate particle size, both followed by long‐term (average LW density increased...

Failure analysis is important in determining root cause for appropriate corrective action. In order to perform failure of microelectronic application-specific integrated circuits (ASICs) delidding the device often required. However, from front side not always possible due shadowing effects caused by ASIC metal interconnects. Therefore, back-side polishing used reveal an unobstructed view silicon transistors. This paper details how conjunction with laser-scanned imaging (LSI), laser voltage...

Abstract An application-specific integrated circuit (ASIC) for a high reliability application is found to have missing sidewall spacer in single transistor. Manufacturer burn-in and standard component electrical tests do not capture this defect. The defect manifests after exposure ionizing radiation. Photon emission microscopy (PEM), laser voltage imaging (LVI), laserassisted device alteration (LADA) are used isolate the failure site. At site focused ion beam (FIB) cross section indicates...

This paper presents the purpose, approach, goals and progress of tasks that make up standard for a digital Ship Product Model. The Navy/Industry Digital Data Exchange Standards Committee (NIDDESC) will be part Standard Model (STEP) International Standard. STEP has layered architecture in which basic core definitions are used by many industry product specific standards such as NIDDESC Standards.
