Small rafts of floating sediment, predominantly of granule and small pebble size, were observed along a tidewater coast on James Ross Island, Antarctica. The sediment was lifted from the beach by the advancing tidewater and kept afloat by surface tension. The current transported the rafts at least 100-150 m off the beach, where the rafts broke up due to wind agitation of the sea surface and the gr
Psoriatic arthritis (PsA) is a chronic musculoskeletal inflammatory disease found in up to 30% of psoriasis patients. Prolargin—an extracellular matrix (ECM) protein present in cartilage and tendon—has been previously shown elevated in serum of patients with psoriasis. ECM protein fragments can reflect tissue turnover and pathological changes; thus, this study aimed to develop, validate and charac
Bone marrow edema (BME) is one of the most common findings on magnetic resonance imaging (MRI) after an ankle injury but can be present even without a history of trauma. This article will provide a systematic overview of the most common disorders in the ankle and foot associated with BME. The presence of BME is an unspecific but sensitive sign of primary pathology and may act as a guide to correct
In the late 19th century Meru smallholders established the first irrigation furrows on Mount Meru, Tanzania with the intent to prolong farming seasons and improve harvests. Soon neighbouring estate holders followed suit. Since then there has been a continuous construction of furrows by both smallholders and estates in the area. Smallholders’ furrows were from the onset managed as de facto communal
There are many projects in Mozambique for poverty reduction. One of these projects is funded by Millennium Challenge Account (MCA) and is aimed to install a total of 600 rural water points in the provinces of Nampula and Cabo Delgado. Each water point consists of a drilled well, a water pump and a communal washing basin. Vertical Electrical Sounding (VES) was used for assessing the uitability of
Design methods are necessary to support product development companies in improving their product development processes, and thereby in producing high quality products. The uptake of design methods in product development companies is limited and lower than one might expect. There is a wide variety of literature related to factors that influence the uptake of design methods in companies. In this pap
A 12 GHz PLL with digital output phase control has been implemented in a 90 nm CMOS process. It is intended for LO signal generation in integrated phased array transceivers. Locally placed PLLs eliminate the need of long high frequency LO routing to each transceiver in a phased array circuit. Routing losses are thereby reduced and design of integrated phased array transceivers become more modular.
Education reforms in Iran is the most recent endeavor of the theocratic state to enhance the vision of the revolution in creating homo-Islamicus (the committed Muslim) and provide strategies for the national education to meet the demands of a globalized and competing world. The reform is the interplay of a rigid interpretation of religion, international discourse and local needs. On one hand, it i
This paper discusses design and measurements of a flexible Viterbi decoder fabricated in 130-nm digital CMOS. Flexibility was incorporated by providing various code rates and modulation schemes to adjust to varying channel conditions. Based on previous trade-off studies, flexible building blocks were carefully designed to cause as little area penalty as possible. The chip runs down to a minimal co
