Genetic variation and evolutionary analysis ofPepino mosaic virusin Sicily: insights into the dispersion and epidemiology
2017
Pepino mosaic virus (PepMV) is a highly infectious potexvirus that causes a severe disease in tomato (Solanum lycopersicum) crops worldwide. In Sicily, the first outbreak was detected in a single greenhouse in 2005 and it was promptly eradicated. However, in 2008, a large number of greenhouses were simultaneously affected, and it was impossible to eradicate or control the virus. This study addressed the dispersion and the genetic diversity of PepMV isolates obtained from the outbreak in Sicily, in comparison with worldwide PepMV isolates, to gain insight into the factors determining the evolution and epidemiology of the virus. A total of 1800 samples from plants with and without symptoms we…
Bromoviridae dzimtas augu vīrusu apvalka proteīnu N-terminālo daļu īpašību pētījumi
2016
Bakalaura darba mērķis ir pārbaudīt ekspresēto un attīrīto ApMV un CMV CP N-gala sajūgtos domēnus ar eGFP dimerizācijas-oligomerizācijas īpašības, kas varētu turpmāk tikt izmantotas imunizācijas eksperimentiem. Darba gaitā tika izveidotas trīs konstrukcijas, kur CP N-terminālie domēni tika ģenētiski savienoti ar eGFP modeļproteīnu un sešu histidīnu atkārtojumiem sajūgto proteīnu attīrīšanai. Sajūgtie proteīni tika noekspresēti un, attīrīti ar afīno hromatogrāfiju. Nukleīnskābes kustīguma nobīdes eksperimenti parādīja, ka ar Zn2+ audzētam nApMV-eGFP ir augstāka afinitāte pret CP mRNS un PCR, nekā audzētam bez Zn2+. Visām N-gala proteīniem ir augstāka afinitāte pret CP mRNS nekā pret CP PCR. …
Vernacular and bioclimatic architecture and indoor thermal comfort implications in hot-humid climates: An overview
2018
Abstract Sustainable urban development, especially in disadvantaged regions, has increasingly gained a major strategic priority. New settlements and urban regeneration programs have to achieve an improvement of social life quality, promote economic growth and increase environmental protection practices and proper use of local resources. In this framework, building environment development must exploit natural resources with responsible approach by using local materials and traditional techniques. In this end, indoor comfort and energy consumption have to match the territories needs. Low energy and passive heating/cooling techniques should be considered as a valid option in many building proj…
The Sliced COO Format for Sparse Matrix-Vector Multiplication on CUDA-enabled GPUs
2012
Abstract Existing formats for Sparse Matrix-Vector Multiplication (SpMV) on the GPU are outperforming their corresponding implementations on multi-core CPUs. In this paper, we present a new format called Sliced COO (SCOO) and an effcient CUDA implementation to perform SpMV on the GPU. While previous work shows experiments on small to medium-sized sparse matrices, we perform evaluations on large sparse matrices. We compared SCOO performance to existing formats of the NVIDIA Cusp library. Our resutls on a Fermi GPU show that SCOO outperforms the COO and CSR format for all tested matrices and the HYB format for all tested unstructured matrices. Furthermore, comparison to a Sandy-Bridge CPU sho…
The control of indoor thermal comfort conditions: introducing a fuzzy adaptive controller
2004
The control and the monitoring of indoor thermal conditions represents a pre-eminent task with the aim of ensuring suitable working and living spaces to people. Especially in industrialised countries, in fact, several rules and standards have been recently released in order of providing technicians with suitable design tools and effective indexes and parameters for the checking of the indoor microclimate. Among them, predicted mean vote (PMV) index is often adopted for assessing the thermal comfort conditions of thermal moderate environments. Unfortunately, the PMV index is characterised by non-linear features, that could determine some difficulties when monitoring and controlling HVAC equi…
CHARACTERIZATION OF A STRAIN OF PEPINO MOSAIC VIRUS FOUND IN SICILY
2006
During winter 2005, an unusual virus-like yellow leaf disorder associated to interveinal leaf yellowing and marbling on fruits, was observed in some greenhouse tomato crops in Sicily, exactly in province of Ragusa. Two leaves from 250 symptomatic tomato plants were serologically tested by DAS-ELISA technique using the sera to Tomato spotted wilt virus (TSWV), Impatiens necrotic spot virus (INSV), Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV) and Pepino mosaic virus (PepMV). Of the 250 samples tested, 215 were positive to PepMV presence. This virus was mechanically transmitted to Cucumis sativus “Cubit”, Datura metel, Nicotiana benthamiana and tomato “Rio Grande”. The host range of…
Thermo-hygrometric comfort in the lecture hall of a library: methodology and experimental evidence.
2012
The present study verifies the thermo hygrometric comfort conditions in subjects of a university library users, evaluating the differences and peculiarities in the data collected at the measurement campaign. Particularities of the investigation is the period studied concerning the time frame of the Middle season, which is not expected to power the air conditioning systems. Based on assumptions on the thermal resistance of clothing in the spring and the metabolic type of subjects, the environmental parameters were monitored in some work position in the reading hall in the library of the Faculty of Medicine and Surgery of the University of Palermo. The article presents analyses of the measure…
