It is now well established that the source ofoxygen in photosynthesis is water. The earliest suggestionpreviously known to us had come from Rene´ BernardWurmser (1930). Here, we highlight an earlier report byMonsieur De Fourcroy (1787), who had already discussedthe broad outlines of such a hypothesis in a book onChemistry written for women. We present here a freetranslation of a passage from this

In L.E. v. Greece, the European Court of Human Rights found that Greece failed to fulfill its positive obligations under art.4 of the European Convention on Human Rights (ECHR). The judgment can be assessed as a step forward for alleviating the scarcity of judicial engagement with art.4 of the ECHR (the right not to be subjected to slavery, servitude, forced labour and human trafficking). While ov

Element 115 är arbetsnamnet för det grundämne som karaktäriseras av att atomer av ämnet har 115 protoner i sin atomkärna. Protoner är positivt laddade kärnpartiklar och är ansvariga för att atomkärnor omges av lika många negativt laddade elektroner för att bilda fullvärdiga neutrala atomer. Olika grundämnen -- såsom guld, syre och tellur -- kännetecknas av att atomerna har olika många protoner, ocThis thesis is devoted to detailed studies of element 115 decay chains using the highly efficient multi-coincidence alpha, electron, gamma and X-ray detector setup TASISpec at the gas-filled separator TASCA at GSI, Darmstadt, Germany. In a three-week long experiment thirty new decay chains assumed to stem from element 115 isotopes were observed together with the very first detections of gamma rays

Healthcare is increasingly a collaborative effort in- volving caregivers from several different organizations providing services to the same patient. This is particularly the case in care for the elderly and chronically ill, where a preference for care in the home is common. Current systems lack support for care scenarios that require mobility and intra-organizational collaboration. This results i

This research addresses local governance for building energy efficiency. In order to turn an increasingly proactive environmental policy agenda at subnational levels into practice, local governments experiment with new forms of governance. One important policy area in this regard is building energy use, often addressed through urban development projects. Such initiatives provide important insight

Periampullary adenocarcinoma, including pancreatic cancer, is a heterogeneous group of tumours with dismal prognosis, for which there is an urgent need to identify novel treatment strategies. The human epithelial growth factor receptors EGFR, HER2 and HER3 have been studied in several tumour types, and HER-targeting drugs have a beneficial effect on survival in selected types of cancer. However, t

Atypical femoral fractures are insufficiency fractures in the lateral femoral diaphysis or subtrochanteric region that mainly affect older patients on bisphosphonate therapy. Delayed healing is often seen in patients with incomplete fractures (cracks), and histology of bone biopsies shows mainly necrotic material inside the crack. We hypothesized that the magnitude of the strains produced in the s

Technology scaling in advanced CMOS nodes has been very successful in reducing the cost and increasing the operating frequency, however, it has also resulted in reduced transistor intrinsic gain and increased thermal noise coefficient, and most importantly, deteriorated linearity performance. At the same time, advanced wireless communication standards offer ever increasing data rates and pose m

Infrared cameras can be used in science education. The technology suits open-ended thermodynamics laboratory exercises in higher education. School children engage in instant inquiry of thermal phenomena.
