The relationship between economic development and environmental quality is a debated topic. Environmental Kuznets curve (EKC) is one prominent hypothesis, positing an inverted U-shaped development-environment relationship. Here we test this hypothesis using data from Shenzhen, People's Republic of China. Established in 1980 as the first special economic zone in China, Shenzhen has developed from a

We show that random pair densities that can arise from a many-body wavefunction have a distinct distribution of their eigenvalues, when interpreted as a kernel of an integral operator. This gives a probabilistic condition for pair densities as well as two-particle density matrices to be obtainable from a wavefunction. The condition depends on the number of particles in the system.

Direct microcalorimetry was used for measurements of heat production in cell suspensions of platelets and adipocytes, obtained from hypothyroid patients before and after 3 months on full L-thyroxine substitution. Platelet heat production was significantly lower than normal before treatment and increased in all 10 patients studied; the mean value increased from 51.3 +/- 1.6 fW/cell before to 57.1 +

It is widely accepted that the bioavaiiability, toxicity, and mobility of trace metals are highly dependent on complexation reactions with functional groups in natural organic matter (NOM). In this study, the coordination chemistry of Cd in NOM was investigated by extended X-ray absorption fine structure spectroscopy. Soil organic matter (SOM) from different types of organic soils and dissolved or

We recently demonstrated that the LKB1 tumour suppressor kinase, in complex with the pseudokinase STRAD and the scaffolding protein MO25, phosphorylates and activates AMP-activated protein kinase (AMPK). A total of 12 human kinases (NUAK1, NUAK2, BRSK1, BRSK2, QIK, QSK, SIK, MARK1, MARK2, MARK3, MARK4 and MELK) are related to AMPK. Here we demonstrate that LKB1 can phosphorylate the T-loop of all

Objectives. Polyarteritis nodosa (PAN) is a term that has been used to describe a wide variety of vasculitic conditions. In 1994, the Chapel Hill Consensus Conference on the nomenclature of systemic vasculitides proposed that the name classical PAN should be restricted to diseases where there is arteritis in small and medium-sized arteries without the involvement of smaller vessels. Our aim was to

The effects of ATP and histamine on cell proliferation and intracellular calcium concentrations ([Ca2+]i) were examined in the human ovarian cancer cell line SKOV-3. Micromolar concentrations of ATP induced a biphasic increase in [Ca2+]i representing a rapid rise to a peak level followed by a smaller but more sustained phase. When influx of extracellular calcium was blocked by calcium chelation to

Genetic engineering has been used for fusion of the peptide tag, Trp-Pro-Trp-Pro, on a protein to study the effect on partitioning in aqueous two-phase systems. As target protein for the fusions the cellulase, endoglucanase I (endo-1,4-β-d-glucan-4-glucanohydrolase, EC 3.2.1.4, EGI, Cel7B) of Trichoderma reesei was used. For the first time a glycosylated two-domain enzyme has been utilized for add

Objective To compare the rate of prenatal diagnosis of heart malformations between two policies of screening for heart malformations. Design Randomised controlled trial. Setting Six university hospitals, two district general hospitals. Sample A total of 39 572 unselected pregnancies randomised to either policy. Methods The 12-week policy implied one routine scan at 12 weeks including measurement o

OBJECTIVE: To evaluate the feasibility of monophasic action potential (MAP) mapping using a modified-tip NaviStar catheter in swine and humans. METHODS: MAP mapping was performed using the modified-tip catheter at 71 +/- 21 atrial and 60 +/- 16 ventricular sites in 10 healthy pigs and at 56 ventricular sites in one patient, and using an ordinary Navi-Star catheter at 30 atrial sites in one patient

The authors' intention is to show that there are other criteria when optimising digital filters than minimising the filter order. The final result in the form of minimum silicon area or few machine cycles in a high-speed custom DSP are aims that are important in a custom design process. It is not an axiom that the minimum order of the filter gives the optimum result. Algorithms with trivial coeffi

The tegumental glands of Derocheilocaris typica are tricellular. Their openings are formed by two transformed epidermal cells, each with a microvillar crown. These cells form a cuticular socket housing the tip of the underlying secretory cell. From the outside, the gland openings are seen as,a pit in the cuticle, from the bottom of which a thin cuticular chimney ends with a slit-like pore. The gla

Fractures of the femoral neck, that is, "cervical hip fractures" constitute 53% of all fractures of the proximal femur (hip fractures) according to the Swedish National Hip Fracture Register linked to SAHFE (Standardised Audit of Hip Fractures in Europe). The most reproducible classification system divides cervical hip fractures into undisplaced (33%) and displaced (67%). Hip fractures are common

Total energy use during the life cycle of a building is a growing research field. The embodied energy makes up a considerable part of the total energy use in low energy buildings. Recycling provides the opportunity to reduce the embodied energy by using recycled materials and reusable recyclable materials/components. This paper presents values on embodied energy. energy needed for operation and th

In 1996 DG XII of the European Commission (Research and Development) approved a 3 year project on the fire performance of electrical cables. Within this FIPEC project, a major part of the work involved correlation and mathematical modelling of flame spread and heat release rate in cable installations. The FIPEC project has developed different levels of testing ranging from a small-scale, cone calo

BACKGROUND. Recurrence rates after surgical repair of groin hernia vary between 3% and 20%. One possible reason for recurrent hernias are ipsilateral multiple hernias, which might have been overlooked at the primary operation. METHODS. In the present series 1010 patients with unclear groin pain underwent herniography. RESULTS. A total of 314 patients had hernias, and seventy-one (23%) of these had
