IntroductionThe incidence of hyperuricemia (HUA) at younger ages is increasing along the coastal regions of China. This study aimed to compare the frequency of dual energy CT (DECT) urate crystal deposition between symptomatic hyperuricemic children and asymptomatic hyperuricemic children.Material and methodsFifty-six hyperuricemic children were divided into a Joint Group (n = 33) and an Asymptomatic Group (n = 23) according to whether they had a history of arthritis symptoms, which includes rapid onset monoarthritis with intense pain and swelling. We analyzed DECT scans of their feet from the Joint Group and the Asymptomatic Group and compared their clinical features.ResultsDECT urate deposits were observed in 28/33 (84.8%) children with symptomatic HUA and 14/23 (60.9%) with asymptomatic HUA. We found 60 areas of urate deposition in the Joint Group; DECT urate crystal deposition was most frequently observed in the first metatarsophalangeal (MTP) joint (30.0%), ankle joint (15.0%), and calcaneus (13.3%). 39 urate deposits were found in the Asymptomatic Group; DECT urate crystal deposition was most frequently observed in the calcaneus (25.6%), the first MTP joint (17.9%), and the first phalanx (15.4%).ConclusionsUrate deposition can occur in children with HUA, and these deposits occur more frequently in hyperuricemic children with a history of arthritis symptoms. Also, the urate deposition in the first MTP joint and calcaneus was more prevalent than in other joints. It is important to give more attention to hyperuricemic children.

Field work was carried out from 17 July to 3 August by a joint group from ARCO, AGIP and GGU to evaluate the reservoir potential of the Upper Permian limestones in Wegener Halvø (fig. 1). The group was based south of Paradigmabjerg (fig. 1) and had a Bell 206 helicopter available tull-time during the entire period. Logistic support was provided by the ARCO base at Constable Pynt. The Upper Permian limestones in the Wegener Halvø area have been investigated previously by GGU (Stemmerik, 1979; Surlyk, 1983; Surlyk et al., 1984a,b, 1986a; Hurst et al., 1989). Diagenetic studies of the limestones (Scholle, 1986; Hurst et al., 1989) indicate that reservoir properties are expected mainly to occur in the bryozoan-cement mounds of the Wegener Halvø Formation. Accordingly, the 1988 programme concentrated on more detailed studies of these mounds and included a shallow drilling programme conducted by GGU (see Christiansen & Stemmerik, 1989).

The aim of this systematic review was to indicate and discuss the use of electromyogram in football. For the literature review, following electronic databases were used: Google School, PubMed, Medline and Mendeley for the period from 2005. to 2019. 20 papers were selected for this systematic review based on the established criteria. These studies focused the most on researching the following muscles: m.musculus quadriceps, m.biceps femoris, m.gastrocnemius, m.tibalis anterior and m. gluteus maximus. The review has determined quite a heterogenic choice of topics when it comes to the use of the electromyogram (herein after referred to as: EMG) in football, so the obtained results were grouped based on the similar characteristics. Therefore, the results were categorized according to the following topics: acute effects of the specific football activity, impact of the football strength training, training of kicking on the ball, results based on the difference in sexes, while the rest of the results were sorted in the joint group. Summarizing of the obtained results provides the insight in the multiple possibility for use of EMG in football in order to develop high quality analysis of the neuro-muscle activation of a certain muscle regions of the football players.

Abstract The article supplements and revises past historiographical explanations on why the US entered World War ii without propellant based engines, for tactical rockets and how that gap was overcome. Short range rockets were used extensively by all sides in the War for various purposes, but in the interwar period (1919–1939), rocket advances were made mostly in Europe with the US lagging behind. The rockets engines were based on solid propellant tubes, but in 1940 there was hardly any US tubes design knowledge and no production facilities. Technological and production gaps had to be closed, and from 1940 were made with a significant help from Britain and under the leadership of the civilian National Defense Research Council (ndrc) agency, merged in 1941 into the Office of Scientific Research and Development (osrd). Due to the pressing needs to equip American forces with rockets, a joint group of ndrc and Army developers modified in early 1942 an existing gun propellant production technology for rocket tubes. Used initially for the Bazooka this adoption was found later to be extremely problematic in production and performance of tubes in the widely-used, Army’s 4.5-inch barrage and fighter plane rockets. Working in parallel, a joint group of ndrc and navy developers was able to construct the more modern tube production process already used abroad, avoiding the main army difficulties and taking the lead. The growing needs for these superior Navy rockets, some of which were used extensively by the Army, led to gaps between supplies and demands by 1943. Two fortunate events, one of them connected with the Soviet Union, helped to relieve the shortage.
