The dependence of vegetation attenuation on propagation geometry has been experimentally investigated at SHF band for isolated single trees. Two measurement heights (Trunk and Canopy) have been used in these experiments that involve three fully foliated trees, Common Whitebeam (Sorbus aria), Silver Maple (Acer Saccharinum) and Common Hazel (Corylus Avellana). Result shows that apart from freque...

We present new numerical characterization of DNA sequences that is based on the modified graphical representation proposed by Hamori. While Hamori embeds the sequence into Euclidean space, we use analogous embedding into the strong product of graphs, K4 ×Pn, with weighted edges. Based on this representation, a novel numerical characterization was proposed in [Pesek and Žerovnik, MATCH Commun. M...

Taxanes are widely known as great family of antitumor compounds. Identification of certain taxanes, particularly taxol, has opened new perspectives for further researches in plant and medical sciences. The aim of the present study was to manipulate chromatographic method in order to detect and quantified novel trace taxanes in suspension-cultured hazel (Corylus avellana L.) cells. A rapid growi...

We present a genome assembly from an individual male Apoderus coryli (the hazel leaf roller; Arthropoda; Insecta; Coleoptera; Attelabidae). The sequence is 428 megabases in span. majority (98.90%) of the scaffolded into 20 chromosomal pseudomolecules, with X and Y sex chromosomes assembled.

abstract agriculture activity is obvious type of unsafely and risky activities that this part had dealt with lack of trast about amount of production and price as unpleasant atmosphere phenomona, calamities, kind of plant diseases and change in prices. insurance is one of important cases for decreasing risk in agriculture. the main of this research is consideration crop insurance’s affect on op...

Hazel is an important source of tree pollen allergens, which are responsible for inhalant allergy symptoms in early spring. The aim the study was to compare Corylus season 2022 12 cities located different regions Poland: Bialystok, Bydgoszcz, Cracow, Kielce, Lublin, Olsztyn, Piotrkow Trybunalski, Sosnowiec, Szczecin, Warsaw, Wroclaw and Zielona Gora. measurements were conducted using a Burkard-...

Longitudinal shifts in pollen onset, duration, and intensity are public health concerns for the growing number of individuals with sensitization. National analyses long-term changes influenced by how a plant's main season (MPS) is defined. Prior Swiss studies have inconsistently applied MPS definitions, leading to heterogeneous conclusions regarding magnitude, directionality, significance multi...
