The authors describe a case of pneumocephalus following epidural anaesthesia for total knee arthroplasty. Multiple attempts in locating the epidural space for the anaesthesia and the use of loss of resistance to air (LORA) technique were identified as the source of air entry. Supportive management was given including high flow oxygenation therapy and spontaneous reabsorption of air was noted fi...

Scutellaria is widely used in traditional medicine as a medical plant, in Asian countries, especially in China. It has been applied in treatment because of its sedative, antithrombotic, anti-inflammatory, antioxidant, and antiviral effects. Scutellaria condensata Rech. f. subsp. pycnotricha (Rech. f.) Rech. f. is a wild perennial plant which  grows in Iran. In this study, GC-FID and GC-MS were ...

This research creates a weather station prototype using LoRa wireless technology. The internet of things (IoT) system is supported by LoRa, networking technology an alternative to existing communication modules such as GSM modules, Wi-Fi and Bluetooth (BLE). network used extend the range cells, allowing them reach distances up 10 kilometers while consuming very little power. End devices can be ...

Public and academic discourses about the Polar regions typically focus on the so-called natural environment. While, these discourses and inquiries continue to be relevant, the current article asks the question how to conceptualize the on-going industrial and infrastructural build-up of the Arctic. Acknowledging that the "built environment" is not an invention of modernity, the article neverthel...

Leptospirosis is a neglected emerging infectious disease with high burden in Africa. Major reservoirs of leptospirosis are rodents and other small mammals. Studies of leptospirosis in bats and the extent to which they contribute to its transmission to humans and domestic animals in Tanzania are lacking. The objective of this study was to determine the prevalence of leptospirosis and local Lepto...

UAVs can be used as aerial relays to provide communication services in remote uncovered areas or dense environments with occasional high capacity demands. However, due the low power of Internet-of-Things (IoT) devices, UAV-based IoT applications, such precision agriculture and environment monitoring, may experience shadowing equipment failure, which degrades communications’ quality between devi...
