A system-level power saving approach for cellular networks with microcells/picocells
2011
Network power consumption reduction has recently become an active research topic. In this paper, we propose a novel approach to save power consumption of a three-cell microcellular network. When the traffic load in the middle cell is low, it can be switched-off and its users are covered. This is enabled by increasing the transmission power of one sector antenna in the two neighboring cells. Numerical results show that by increasing antenna transmission power of the two sectors, the overall network power consumption can be reduced.
Sex-specific responses to mycorrhiza in a dioecious species.
2011
In most studies about dioecious plants, the role of arbuscular mycorrhizae (AM) and the potential sex-specific differences between the plant hosts have been overlooked. Because plant sexes frequently differ in drought tolerance and AM fungal colonization provides higher resistance to drought, we investigated whether the relation of mycorrhizal fungi with either male or female Antennaria dioica plants differs using a factorial experiment. We hypothesized that because AM usually increase growth rate and male plants usually grow larger than females, males should gain more benefit from the mycorrhizal symbiosis in terms of mineral nutrition and water supply. Because of higher demands of carbohy…
Design of a narrow-band filter based on the Brewster phenomenon for microwave applications
2017
A high-efficiency narrow-band filter based on a Dielectric Frequency-Selective Surface (DFSS) has been predicted theoretically for oblique plane-wave incidence. A DFSS showing total reflection at a frequency of 10.5 GHz, based on the Brewster phenomenon for TM polarization, has been designed with a single dielectric grating, showing extremely low-reflectance sidebands adjacent to the resonance peak. The angular and spectral response of the designed filter has been studied. In addition, dielectric ohmic losses have been accounted for in this structure. This work was supported by the Agencia Estatal de Investigación (AEI) and by the Unión Europea through the Fondo Europeo de Desarrollo Region…
In situ localization of the Antennapedia gene on the chromosomes of nine Drosophila species of the obscura group.
2008
The homeotic Antennapedia gene, cloned from the genomic DNA of D. subobscura, was localized on the polytene chromosomes of nine species of the Drosophila obscura group. In all of them, the probe used hybridized on chromosomes equivalent to the E element of Muller's terminology. These results are consistent with the idea that single copy genes do not move around the genome and that chromosomal elements have conserved their genetic identity during evolution.
La tutela della salubrità dell'aria e della persona in civil Law e in common Law
2022
The essay deals with safeguarding the right to a healthy environment in the Italian and English systems, especially for the individuals affected by emissions that corrupt the air quality interfering with their private and family life. The study focuses on the injunction, as a non-compensatory remedy, actionable before the English courts by claimants seeking the decontamination of the polluted areas. The insight into the foreign environmental law will provide a new perspective on the Italian one that (as the European Court of Human Rights stated in the Cordella case) does not secure everyone an effective remedy to the violation of their environmental human right.

Rosyjska koncepcja Eurazjatyckiego Systemu Obrony Powietrzno-Kosmicznej. Analiza problemu
2018
Autorka artykułu omawia na tle uwarunkowań geopolitycznych Rosji najważniejsze tezy planu A. Podbieriezkina, które tworzą paradygmat wspólnego bezpieczeństwa w ujęciu rosyjskim na strategicznym obszarze Eurazji. Ma to szczególne znaczenie w obliczu wzrastających zagrożeń współczesnego świata. Szczególnie niebezpieczny charakter, w związku z przeprowadzaniem prób jądrowych i nieobliczalnym reżimem Kim Dzong Una, przybiera obecnie problem Korei Północnej, co rodzi zagrożenie, że nagły i. ARTYKUŁY i rozprawy 85 konflikt może wciągnąć Półwysep w wojnę. To z kolei z pewnością doprowadziłoby do interwencji Stanów Zjednoczonych. Skutki ewentualnego konfliktu z udziałem supermocarstwa są nie do prz…

The article discusses source materials for history o f Polish-Lithuanian Commonwealth Dietines, found in archival legacy o f Ludwig Gruno, Prince o f Hesse-Homburg. The documents are part o f field chancellery o f the prince, currently preserved in the Military-Historical Museum of Engineer and Signal Corps in St. Petersburg among over a thousand of letters, documents and files illustrating his achievements as commander o f Russian armies in the Caucasus and Poland in 1732-1736. The documents pertain mostly to tsarist army exacting war tribute in form o f food and feed in South- Eastern voivodeships from autumn 1734 to 1736. It was a significant burden to noblemen in Ukrainę, Podolia, Volhy…

Enhanced Accumulation of Betulinic Acid in Transgenic Hairy Roots of Senna obtusifolia Growing in the Sprinkle Bioreactor and Evaluation of Their Bio…
2021
Betulinic acid, which is found in transgenic roots of Senna obtusifolia (L.) H.S.Irwin & Barneby, is a pentacyclic triterpene with distinctive pharmacological activities. In this study, we report the differences in the content of betulinic acid and selected anthraquinones in transgenic S. obtusifolia hairy roots with overexpression of the PgSS1 gene (SOPSS2 line) and in transformed hairy roots without this genetic construct (SOA41 line). Both hairy root lines grew in 10 L sprinkle bioreactor. Additionally, the extracts obtained from this plant material were used for biological tests. Our results demonstrated that the SOPSS2 hairy root cultures from the bioreactor showed an increase in the c…
