SUMMARY Cystic parenchymal lesions may pose an important diagnostic challenge, particularly when encountered in unexpected locations. Dilated perivascular spaces, which may mimic cystic neoplasms, are known to occur in the inferior basal ganglia and mesencephalothalamic regions; a focal preference within the subcortical white matter has not been reported. This series describes 15 cases of patie...

the incidence of multiple myeloma (mm) affecting the jaws is 30% and on rare occasions the oral involvement can be the first indication of the disease. authors report a case of mm in a 40-yearold woman who presented with a multilocular radiolucent lesion in the left mandible initially mistaken as an ameloblastoma. conventional radiographs revealed a multilocular lesion on the molar region. comp...

Among the key acoustic features attributed with the intelligibility gain of Clear speech are the observed reduction in speaking rate and expansion of vowel space, representing greater articulation and vowel discrimination. Considering the slower speaking rate, previous works have attempted to assess the intelligibility impact of time-scaling casual speech to mimic Clear speech. In a complementa...

Introduction Subacromial impingement syndrome (SIS) is a general term used to describe a variety of conditions that may act independently or in combination, and manifest as anterior or anterior-lateralsuperior shoulder pain. SIS occurs as a result of pathology of one or more of the structures located within the subacromial space. The pain is associated with a loss of shoulder function, especial...

If similar compounds have similar activity, rational subset selection becomes superior to random selection in screening for pharmacological lead discovery programs. Traditional approaches to this experimental design problem fall into two classes: (i) a linear or quadratic response function is assumed (ii) some space filling criterion is optimized. The assumptions underlying the first approach a...

This study presents the regional estimates of the seasonal and diurnal mean broadband (0.3–5.0 mm) clear-sky aerosol radiative forcing at the top of atmosphere (TOA) due to both the natural and the anthropogenic aerosols over the tropical Indian Ocean from 258N to 258S. We propose two new methods, the slope method and the differencing method, to obtain clear sky aerosol forcing from solely sate...

A number of proposed lidar systems, such as ESA’s AEOLUS (formerly ADM) and DIAL missions (e.g. WALES) are to make use of lidar returns in clear air. However, on average, two-thirds of the globe is covered in cloud. Hence, there is a strong likelihood that data from these instruments may be contaminated by cloud. Similarly, optically thick cloud may not be penetrated by a lidar pulse, resulting...

the present article deals with the performing prostration or sajdah, on imam husain’s turbah, the clay obtained from karbala where imam husain (pbuh) attained his holiness’s martyrdom. in so doing, we first investigate the superiority of prostration on clay, found in islamic narrations and traditions from shiite and sunnite points of view. it is upon these traditions that we prove that prostrat...

cerium oxide (ceria) nano particle, as photodegradation prevention agent was studied in water-based polyurethane clear coat  systems. polyurethane coatings show superior weathering resistance compared with acrylic melamine systems. however, any chemical change has detrimental effects on the property profile of pu coatings. coatings containing various amounts of cerium oxide nanoparticles were p...

ABSTRACT The suggestions for writing for publication given in this paper include writing with honesty, thinking clearly, considering the potential audience, sharing the article with friends, revising the article, and sending the article to the appropriate journal. Empathy for the difficulty of writing is given and illustrated with examples from Eric Hcffer, Ernest Hemingway, Art Buchwald, Chaim...
