Considerable progress in our understanding of long-distance migration has been achieved thanks to the use small geolocator devices (GLS). The tracking resident or short-distance migrant animals remains however challenging because geolocation errors are substantial and difficult estimate. This study aims examine sex-specific marine space uses a tropical seabird, masked booby (Sula dactylatra), d...
A hybrid Svyatogor F1 of Dutch breeding was grown in a winter greenhouse for three turns. Studies have shown that pre-sowing seed soaking treatment and foliar top dressing plants with potassium humate did not affect germination, but positively affected plant growth, except lithium carbon dioxide. For PABA, the leaf area increased, while it decreased. Micro fertilizers, lithium, had positive eff...
Tri-axial accelerometry has proved to be a useful technique to study animal behavior with little direct observation, and also an effective way to measure energy expenditure, allowing a refreshing revisit to optimal foraging theory. This theory predicts that individuals should gain the most energy for the lowest cost in terms of time and energy when foraging, in order to maximize their fitness. ...
In rats, the rates of 50 kHz ultrasonic vocalizations (USVs) can be used as a selective breeding phenotype and variations in this phenotype can be an indicator of affective states. The 50 kHz USV is elicited by rewarding stimuli (e.g., food, sexual behavior) and therefore can express a positive affective state. Conversely, the 22 kHz USV is elicited by aversive stimuli (e.g., presence of a pred...
today, there are many concepts such as a sense of place and attachment to place presented in architecture and urban literature in the field of environmental studies. meanwhile, relationship between the two is not much explained. this study defines the concept of sense of place and attachment to place and the factors influencing them followed by providing a four- dimensional model derived from s...
M1 muscarinic receptor has been shown to be involved in cognitive functions of the brain. Conditioned place preference (CPP) paradigm involves memory for the association between environmental stimuli and the rewarding properties produced by a treatment. Using a balanced CPP design, we studied the possible involvement of M1 muscarinic receptors on the acquisition, expression and consolidation of...
Breeding periodicity allows organisms to synchronise breeding attempts with the most favourable ecological conditions under which to raise offspring. For most animal species, ecological conditions vary seasonally and usually impose an annual breeding schedule on their populations; sub-annual breeding schedules will be rare. We use a 16-year dataset of breeding attempts by a tropical seabird, th...
We consider the computation of Bernoulli, Tangent (zag), and Secant (zig or Euler) numbers. In particular, we give asymptotically fast algorithms for computing the first n such numbers in O(n2(logn)2+o(1)) bit-operations. We also give very short in-place algorithms for computing the first n Tangent or Secant numbers in O(n2) integer operations. These algorithms are extremely simple, and fast fo...
Gate resizing for minimum circuit delay is a fundamental problem in the performance optimization of gate-level circuits. In this paper , we study the complexity of two diierent minimum-delay gate resizing problems for combinational circuits composed of single-output gates. The rst problem is that of gate resizing for minimum circuit delay under the load-dependent delay model. The second problem...
