Damping Properties vs. Structure Fineness of the High-zinc Aluminum Alloys

The subject of this study is the presentation of relation between the degree of structure fineness and ultrasonic wave dampingcoefficient for the high-zinc aluminium alloys represented in this study by the sand mould cast alloy Al - 20 wt% Zn (AlZn20). Thestudied alloy was refined with a modifying (Al,Zn)-Ti3 ternary master alloy, introducing Ti in the amount of 400 pm into metal. Based on the analysis of the initial and modified alloy macrostructure images and ultrasonic testing, it was found that the addition of (Al,Zn)-Ti3 master alloy, alongside a significant fragmentation of grains, does not reduce the coefficient of ultrasonic waves with a frequency of 1 MHz

Flagellate Dermatitis due to Bleomycin Intake

Flagellate dermatitis is a rare cutaneous manifestation in which long, striated erythematous lesion appear on the patient’s skin. It is most frequently associated with bleomycin treatment or Shiitake mushroom intake, but it may also be attributed to many other possible causes. Herein we present a case of striated, hyperpigmented lesions which occurred after bleomycin intake. The typical flagellate lesions appeared for the first time on the patient’s back and shoulders after the first course of chemotherapy for seminoma (bleomycin, etoposide, and cisplatin). The active lesions disappeared with the discontinuation of chemotherapy. Clinicians should be aware of flagellate pattern of dermatitis which may accompany different clinical situation

Operations Management: Processes and Supply Chains -9/E.

OPERATIONS MANAGEMENT PROCESSES AND SUPPLY CHAINS This Global Edition has been edited to include enhancements making it more relevant to studens outside the United States. The editorial taem at Pearson has worked closely with educators around the globe to include: • NEW! Supply Chain Orientation: This text uniquely builds the concept of a supply chain from the ground up allowing students to see how effective internal processes lead the best supply chairs. • NEW! Streamlined Design: Fewer chapters, less pages, and enhanced clarity allows students to engage each topic efficiently and effectively. Figures and photos have been added to improve the presentation of key concepts and techniques. • NEW! Global Examples and Cases: Examples from Europe, Asia, Middle East and Australia are presented throughout the text for students in these regions to better appreciate the concepts presented

Uncertainty In Radar-rainfall Composite And Its Impact On Hydrologic Prediction For The Eastern Iowa Flood Of 2008

Key Points A significant potential source of error exists in mosaicked radar-rainfall maps. Different radar calibration offsets lead to misestimation of rainfall amounts. Systematic error in rainfall significantly affects hydrologic predictions. This study addresses a significant potential source of error that exists in radar-rainfall maps that are combined using data from multiple WSR-88D radars of the Next Generation Radar (NEXRAD) national network in the United States. This error stems from different radar calibration offsets that create a border within discontinuous rainfall fields at the equidistance zone among radars. The discontinuity in rainfall fields could lead to misestimation of rainfall over basins and subsequently, to significant errors in streamflow predictions through a hydrologic model. In this study, we produce enhanced radar-rainfall estimates (HN3) based on a novel approach that allows us to reduce the effects of the relative radar calibration bias. We use the relative bias information previously presented in a radar reflectivity comparison study. To investigate the effects of the relative bias adjustment, we evaluate the HN3 and Stage IV radar-rainfall by comparing them with rain gauge data and analyzing their ability to simulate streamflow for an extreme flood case. While the HN3 estimates are statistically comparable to the Stage IV estimates in the rain gauge data comparison, the borderline that identifies discontinuous rainfall fields disappears in the HN3 estimates. We performed hydrological simulations using a physically based, data-intensive, calibration-free, hillslope-link hydrologic model called CUENCAS and demonstrated CUENCAS\u27s ability to accurately simulate flows by comparing results with observed and predicted streamflow generated by the Sacramento (SAC) model. SAC is the operational flood forecast model that has been used by the National Weather Service since 1969, and it was extensively calibrated based on historical data. The simulation results show that the adjustment improves streamflow predictions in the regions where the misestimation of rainfall quantity is considerable. We conclude that systematic error arising from different calibration offsets in rainfall fields can significantly affect hydrologic predictions. ©2013. American Geophysical Union.

Nevus Sebaceous with Multiple Basal Cell Carcinomas and Extracutaneous Abnormalities: Genetic Origin or Coincidence?

The association of cutaneous and extracutaneous abnormalities is a common phenomenon, widely described in a variety of genetic syn- dromes. Nevertheless, yet undescribed syndromic combinations may still exist. Herein we present a case report of a patient who was admitted to the Dermatology Department due to multiple basal cell carcinomas arising from nevus sebaceous. In addition to the cutaneous malignancies, the patient presented with palmoplantar keratoderma, prurigo nodularis, hypothyroid- ism, multiple lumbar abnormalities, uterine myoma, an ovarian cyst, and highly dysplastic colon adenoma. Such a combination of multiple disorders may indicate a genetic origin of the diseases
