Effects of forest patch size on physiological stress and immunocompetence in an area-sensitive passerine, the Eurasian treecreeper ( Certhia familiar…

2004

We manipulated the primary brood size of Eurasian treecreepers (Certhia familiaris) breeding in different sized forest patches (0.5-12.8 ha) in moderately fragmented landscapes. We examined the effects of brood size manipulation (reduced, control, enlarged) and forest patch size on physiological stress (heterophil-lymphocyte ratios; H/L), body condition and cell-mediated immunocompetence (phytohaemagglutinin test). Nestlings' H/L ratios were negatively related to forest patch area in control and enlarged broods, whereas no effects were found in reduced broods. The effects of forest patch area were strongest in enlarged broods, which had, in general, twofold higher H/L ratios than control an…

Dynamic Animal Populations in Managed Forests: Species Ecological Requirements and Sustainable Harvesting

2015

Forest management has altered forested environments and provoked stress to many natural habitats and biodiversity. The goal of biodiversity management is the long-term persistence of populations in human-modified environments. We demonstrate a spatio-temporal modeling approach to address the relationship between various management objectives and population persistence in the long-term in a commercial forest landscape. We used the flying squirrel (Pteromys volans), the three-toed woodpecker (Picoides tridactylus) and the long-tailed tit (Aegithalos caudatus) as example species. They are all forest species but they have distinctly different habitat requirements. In the model, forest growth, f…

Bifurcation phenomena for the positive solutions of semilinear elliptic problems with mixed boundary conditions

2016

We consider a parametric semilinear elliptic equation with a Cara-theodory reaction which exhibits competing nonlinearities. It is "concave" (sub-linear) near the origin and "convex" (superlinear) or linear near $+\infty$. Using variational methods based on the critical point theory, coupled with suitable truncation and comparison techniques, we prove a bifurcation-type theorem, describing the set of positive solutions as the parameter varies.

African linkage of Precambrian Sri Lanka

1991

New age and isotopic data show that the high-grade basement rocks of Sri Lanka were not linked to the Archaean granulite domain of southern India but experienced their main structural and metamorphic development during the Pan-African event some 950 to 550 Ma ago. This occurred when West Gondwana and East Gondwana collided to form one of the longest collisional structures in the Supercontinent — the Mozambique belt that extends from Mozambique to Ethiopia and Sudan. A major tectonic boundary, interpreted as a thrust zone, divides the Highland/Southwestern Complex in the central part of Sri Lanka from the Vijayan Complex in the E and SE. The former is interpreted to represent the remnant of …

Hepassocin as a treatment for fulminant hepatic failure: will it translate from rats to human?

2010

Acute liver failure (ALF) is defined as the abrupt loss of hepatic cellular function in a patient without pre-existing liver disease, with the subsequent development of coagulopathy, jaundice and encephalopathy. It remains one of the most challenging medical emergencies, due to the multiorgan nature of the disease, the rapid evolution of the clinical condition and the need for multidisciplinary supportive interventions in order to assess the necessity for liver transplantation (LT) correctly.1 Despite different causes of ALF, the mode of cell death typically follows one of two patterns: necrosis or apoptosis; apoptosis is manifest by nuclear and cytoplasmic shrinkage without disturbance of …

Intermittent and passivity based control strategies for a hyperchaotic system

2013

In this paper a four-dimensional hyperchaotic system with only one equilibrium is consid- ered and it is shown how the control and the synchronization of this system can be realized via two different control techniques. Firstly, we propose a periodically intermittent con- troller to stabilize the system states to the equilibrium and to achieve the projective syn- chronization of the system both in its periodic and hyperchaotic regime. Then, based on the stability properties of a passive system, we design a linear passive controller, which only requires the knowledge of the system output, to drive the system trajectories asymptoti- cally to the origin. Using the same passivity-based method, …

Ryt oczyszczenia, celebrowanie Paschy i święta Namiotów w ujęciu proroka Ezechiela (Ez 45,18-25)

2019

Ezechiel był prorokiem głoszącym sąd Boży nad Izraelem oraz nad narodami (Ez 1–32); zapowiadał również odnowę ludu Jahwe i jego ziemi (Ez 33–48). W nowym środowisku Izraela będzie odprawiony ryt oczyszczenia (Ez 45,18-20). Celebrowane będą także święta pielgrzymkowe: Pascha oraz Namiotów (Ez 45,21-25). Ezechiel nawiązuje więc do tradycji z okresu pierwszej świątyni, lecz jego ujęcie tych wydarzeń zostało w pełni dostosowane do nowych warunków – do okresu odnowy narodu i ziemi po powrocie ludu do ziemi przodków. Prorok Ezechiel znając tradycję obchodzenia świąt (~yGIx;), wspomina o nich wyłącznie w kontekście zapowiedzi nowego prawa świątynnego (Ez 45,17.21.23.25; 46,11). Będą to święta wyzn…
