Nerve compression due to benign tumors or ganglion cysts in the upper limb – case series

Tumor nerve compressions in the upper limb are relatively rare, usually involving ganglion cysts and benign tumors. We present a case series of five patients with peripheral nerve compression in the upper limb due to tumor or cystic masses- ulnar nerve compression in the Guyon’s tunnel due to a ganglion cyst, large median nerve schwannoma compressing anterior interosseous nerve and median nerve, voluminous lipoma compressing median nerve in the proximal forearm, superficial branch of radial nerve compression by a synovial cyst and elbow region lipoma compressing radial nerve. In the beginning, those benign lesions are asymptomatic but, as they continue to grow adjacent to a peripheral nerve clinical manifestations appear progressively as compressive neuropathies. After a preoperative imagistic analysis, tumor resection with careful dissection, in order to preserve the neurovascular structures, is the elective surgical procedure in order to obtain an optimal functional recovery

A 2500-yr late holocenemulti-proxy record of vegetation and hydrologic changes from a cave guano-clay sequence in SW Romania

We provide sedimentological, geochemical, mineral magnetic, stable carbon isotope, charcoal, and pollen-based evidence froma guano/clay sequence in Gaura cuMuscă Cave (SWRomania), fromwhichwe deduced that from ~1230 BC to ~AD 1240 climate oscillated betweenwet and dry. From ~1230 BC to AD 1000 the climate was wetter than the present, prompting flooding of the cave, preventing bats fromroosting, and resulting in a slowrate of clay accumulation. The second half of the MedievalWarm Period (MWP) was generally drier; the cave experienced occasional flash flooding in between which maternity bat roosts established in the cave. One extremely wet event occurred around AD 1170, when Fe/Mn and Ti/Zr ratios show the highest values coincident with a substantial increase of sediment load in the underground stream. The mineral magnetic characteristics for the second part of the MWP indicate the partial input of surface-sourced sediments reflecting agricultural development and forest clearance in the area. Pollen and microcharcoal studies confirm that the overall vegetation cover and human land use have not changed much in this region since the medieval times

ENGINEERING EDUCATION FOR SUSTAINABLE DEVELOPMENT – A STRATEGIC FRAMEWORK FOR UNIVERSITIES

Abstract—In the context of striving demands for sustainability actions, education came to play an important role. This role has been recognized and emphasized by the United Nations, when it proclaimed the Decade of Education for Sustainable Development (DESD), 2005-2014. Since the beginning of this decade, universities have done a frenetic work to encompass sustainability principles in their core culture. To face this challenge it was important to understand what makes the difference between a traditional university and a sustainable one. Starting from the literature review, this paper offers a conceptual framework for the future development of sustainability in universities. The sustainable development concept will be presented, emphasizing the role of sustainability and outlining those core activities which should be relevant to any university, especially to the engineering one, in its way to respond to pressure of change rising from sustainability demands

Little Ice Age in Romania in the Vision of a Syrian Traveler

Archdeacon Paul of Aleppo of Damascus accompanied the Patriarch Macarios of Antioch, in Moldavia, Wallachia, Dobrogea for nearly seven years (1652-1659), just in time considered one of the coldest during the Little Ice Age, Maunder Minimum namely (1645-1715). His journey is recorded in his travel diary, written in Arabic and translated into Romanian in 1900. Romanian historians were particularly concerned with the information provided by the passenger about the towns, monasteries, and farmhouses, aspects of daily life, customs, habits and Romanian economy countries. But Paul of Aleppo describe and climate issues, particularly cold winters with frost Danube, snowy, storm at sea, rain, floods, etc. It is a very rich source of information in this area, so far little taken into consideration, showing that the Little Ice Age was also evident in Eastern Europe

Little climate optimum in the Carpathian-Danubian-Pontic space

Our knowledge of climate during the Little Climate Optimum (VIII-XIV centuries) in our country comes from some historical studies on climatic events occurring in countries around Romania: Hungarian, Italian peninsula, Ukraine, the Balkan peninsula and the region around Constantinople, from foreign chronicles, French, German, Russian, from some notes of foreign travelers in that territory. Were record mostly harsh winters, especially in the early interval, with frozen rivers and the Black Sea, or rainy summers, with floods, but also some very warm winters, with the flowering of trees in January, and summers long, hot and dry. Some of these events led to famine, pestilence, high morbidity

Index Bioclimatic "Wind-Chill"

This paper presents an important bioclimatic index which shows the influence of wind on the human body thermoregulation. When the air temperature is high, the wind increases thermal comfort. But more important for the body is the wind when the air temperature is low. When the air temperature is lower and wind speed higher, the human body is threatening to freeze faster. Cold wind index is used in Canada, USA, Russia (temperature "equivalent" to the facial skin) etc., in the weather forecast every day in the cold season. The index can be used and for bioclimatic regionalization, in the form of skin temperature index

SOME ASPECTS OF CLIMATE VARIABILITY DEDUCTED FROM ANALYSIS OF DAYS WITH DIFFERENT THERMAL CHARACTERISTICS

In this article we examined several thermal parameters, namely: the average number of summer days and tropical days in July and annually, and the average number of days with frost and average number of winter days in January and annually, for seven weather stations located in different geographical conditions. A comparison was made between computed values to 1955 and the calculated values for the period 1961-2000. The data were edited by Meteorological Institute, 1966, and the National Agency of Meteorology, 2008
