    Full Text Available The essay presents the full transcription of three notarial records reporting a loan granted by Leonello Spada to a Bolognese fisherman in 1617. Twenty years later, Guido Reni was relieved as a guarantor of the loan and he appointed the painter Marco Bandinelli to the drafting of the record. The poor conditions of the papers compelled the transcription of these documents, which are invaluable proofs of the economic relationships taking place in the Bolognese artistic community.

    Full Text Available Música do Parnasso is a lyrical collection published in 1705 by Manuel Botelho de Oliveira. Speaking of modern Italy, Botelho characterized it – in his dedicatory – as a renewed Greece. The Italian poet Marino emerges within Botelho preferences: Marino is quoted several times directly and indirectly by the Brazilian literate. However, this knowledge was mediated by a little-known manual of an Italian ecclesiastic, Padre Giambattista Spada.

    By revealing the relation between dilation of a subsurface fracture due to pressurization and travel time delay, it may be possible to measure the information as to the subsurface fracture system as a geothermal reservoir. In this study, field experiment was conducted to clarify the relation between the travel time delay of elastic waves and the dilation of fracture, pressure, and incident angles. The travel time delay of P-wave and S-wave tended to increase with the pressurization. When incident angle was about 90{degree} against the fracture, the increase was ranging between 0 and 0.2 ms. The magnitude of this delay could not be explained only by the opening of main fracture. It was considered that there were micro-crack zones around the main fracture. The difference of P-S delay depended on the pressurization and change of the pressure. The delay depended on the incident angle against the fracture. The delay of S-wave showed the polarized wave direction dependency. However, the obtained results might greatly depend on the analytical method and parameters. 4 refs., 10 figs.

    A proposal was given on an equivalent crack tip opening displacement (CTOD) concept which relates quantitatively fracture performance of a structural member with the result of a three-point bending CTOD test via the Weibull stress based on a local approach. The equivalent CTOD is defined as a CTOD in which a three-point CTOD test piece and a structural member provide the same Weibull stress. Experimental and analytical discussions were performed on X80 steel welded joints. Effectiveness of the equivalent CTOD concept was verified from the fact that the fracture performance in welded joints with a large width estimated from the result of the three-point bending CTOD test using the equivalent CTOD concept showed good correspondence with the fracture performance obtained in the experiments. On the other hand, the result of estimation using the conventional CTOD concept is considerably smaller than measurements. As an application of the equivalent CTOD concept, a new determination procedure was introduced on required fracture tenacity to ensure deformation performance required on structural elements. The required CTOD value shows a trend that the smaller the ratio of yield stress of the welded metals to that in the base material, the greater the required CTOD grows. 16 refs., 19 figs., 3 tabs.

    As characterization of artificial cracks formed underground by using the water pressure fracturing method, experiments have been carried out to detect relationship of pressurization and S-wave propagation time with the polarizing direction dependence. Openings are created when pressure in the vicinity of the artificial cracks increases greater than reopening pressure of micro cracks. Elastic wave velocity decreases in this region because of water in the opened micro cracks. Anisotropy is created in the S-wave propagation velocity due to influence from anisotropic reopening region when the artificial cracks are pressurized, and is separated into two components which polarize orthogonally with each other (micro splitting). Field experiments conducted at the Higashi-hachimantai field were analyzed by using wavelet transform. It was possible to detect the S-wave arrival time at high accuracy, and the arrival of an orthogonally polarized wave was observed in 0.03 to 0.11 ms after the arrival of the S-wave. Possibility was indicated on separation of the two components in the orthogonally polarized wave of the S-wave if the micro splitting is used. If this mechanism is elucidated, it may be possible to extract information on cracking systems (direction of micro crack orientation and crack density). 8 refs., 10 figs.

    2009-03-01

    This study investigated cross-cultural differences in the association between negative emotions and alcohol dependence symptoms in British Indian and White college students. Based on a study of levels of alcohol consumption (Spada & Moneta, 2004), it was hypothesized that the association between negative emotions and alcohol dependence symptoms would be present only in British White students. A sample of 150 British Indian students and 150 British White students completed the Alcohol Use Disorders Identification Test (AUDIT) and the Hospital Anxiety and Depression Scale (HADS). Structural regression modeling indicated that negative emotions predict higher levels of alcohol dependence symptoms in British White students, and do not predict alcohol dependence symptoms in British Indian students. The implications of the findings are discussed.

  17. Anomalous secular sea-level acceleration in the Baltic Sea caused by isostatic adjustment

    Full Text Available Observations from the global array of tide gauges show that global sea-level has been rising at an average rate of 1.5-2 mm/yr during the last ~150 years [Douglas 1991, Spada and Galassi 2012]. Although a global sea-level acceleration was initially ruled out [Douglas 1992], subsequent studies [Douglas 1997, Church and White 2006, Jevrejeva et al. 2008, Church and White 2011] have coherently proposed values of ~1 mm/year/century [Olivieri and Spada 2013]. More complex non-linear trends and abrupt sea-level variations have now also been recognized. Globally, these could manifest a regime shift between the late Holocene and the current rhythms of sea-level rise [Gehrels and Woodworth 2013], while locally they result from ocean circulation anomalies, steric effects and wind stress [Bromirski et al. 2011, Merrifield 2011]. Although isostatic readjustment affects the local rates of secular sea-level change [Milne and Mitrovica 1998, Peltier 2004], a possible impact on regional acceleration has been so far discounted [Douglas 1992, Jevrejeva et al. 2008, Woodworth et al. 2009] since the process evolves on a millennium time scale [Turcotte and Schubert 2002]. Here we report a previously unnoticed anomaly in the long-term sea-level acceleration of the Baltic Sea tide gauge records, and we explain it by the classical post-glacial rebound theory and numerical modeling of glacial isostasy. Contrary to previous assumptions, our findings demonstrate that isostatic compensation plays a role in the regional secular sea-level acceleration.

  18. POCHVENNICHESTVO IN RUSSIAN LITERATURE: THE METAPHOR AS IDEOLOGEME

    2012-11-01

    Full Text Available Original as it was, the phenomenon of pochvennichestvo (roughly translated as «native soil» in Russian thought and literature is often accompanied by a number of myths, misperceptions and erroneous commonplaces. It is not infrequent that those who never shared the ideas of pochvennichestvo are described as its adepts, and those who did, are often misquoted, with some notions, ideas and phrases misattributed to them. The ideological and literary agenda of pochvennichestvo was formed by the Vremya (1861-1863 and Epokha (1864-1865 magazines published by the brothers Dostoevsky — Fedor and Mikhail. Their outlook and vigorous action, discussions of submitted articles at board meetings, polemics with other periodicals — all of these factors contributed to the general trend of pochvennichestvo with its typical mutual influence of all its members. Fedor Dostoevsky's role on its development was decisive, as he kept consistently substantiating ideas which were new for Russian literature. Our article analyses the pochva (soil metaphor in the ideology of new school of literature and political movements which Dostoevsky helped set up in 1860s-1870s. According to him, pochva includes everything that gives birth and unites: people, homeland, native language and mother earth. They are all linked together by the mystery of Russia as the keeper of Orthodox faith and Christ as the «ideal of the people». One has to reunite with the pochva by becoming one with the people and strive to see all estates united. To be a pochvennik meant to love Russia and its people, to be a Russian and identify as one, to follow the faith of the fathers and honour the native land. In the 20th century, pochvennichestvo resolved the old argument between the Westernizers and Slavophiles. The word pochvennik was applied to the authors who stayed loyal to Russian traditional values, rural communities and traditions of Russian literature. Various authors and critics have been

  20. Desire thinking: what is it and what drives it?

    Caselli, Gabriele; Spada, Marcantonio M

    2015-05-01

    The aim of this study was to provide an overview of the construct of desire thinking and test a metacognitive model of desire thinking and craving, based on the work of Spada, Caselli and Wells (2012; 2013), which aims to explain the perseveration of desire thinking. We conducted two studies involving four clinical samples (total N = 493) and a community sample (N = 494) presenting with different addictive behaviors. The relationships among variables were examined by testing the fit of path models within each sample. In the model presented it was proposed that positive metacognitions about desire thinking are associated with, in turn, imaginal prefiguration and verbal perseveration, marking the activation of desire thinking. Verbal perseveration is then associated to negative metacognitions about desire thinking and craving denoting the pathological escalation of desire thinking. Finally, a direct association between positive metacognitions about desire thinking and negative metacognitions about desire thinking would mark those occasions where target-achieving behaviour runs as an automatized schemata without the experience of craving. Results indicated a good model fit in the clinical sample and a variation in the model structure in the community sample. These findings provide further support for the application of metacognitive theory to desire thinking and craving in addictive behaviors. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available This study investigates the current teaching trends and practices in teaching oral English in rural Sinhala-medium schools in Sri Lanka and their relevance to the current theoretical, empirical, and pedagogical perspectives of second-language acquisition (SLA. The present study, which was conducted in two Sri Lankan Sinhala-medium rural schools, is a case study in which the classroom observation, interviewing of the participants, and videotaping of students’ interaction were included as data collection tools. The spoken data were analyzed using the Communicative Orientation of Language Teaching (COLT scheme designed by Fröhlich, Spada, and Allen, while the numerical data obtained from the structured speaking test (Cambridge Key English for Schools Test were analyzed using independent samples t test. The findings of the study indicate that the instructional method used by English teachers does not provide the learners with adequate input of the target language to improve their oral communication skills in rural school contexts. As a result, a majority of students from rural schools in Sri Lanka demonstrate a limited or a low proficiency level in oral communication in English. Therefore, possible reasons for the lack of greater awareness towards more communicative teaching are discussed, and suggestions for promoting changes in teaching English as a Foreign Language (EFL in rural school contexts are offered.

  4. Chandler wobble excitation by catastrophic flooding of the Black Sea

    1999-06-01

    Full Text Available It is now widely accepted that during the late Quaternary glaciation the Black Sea formed an isolated inland lake (Ross et al., 1970. New geological data and the recognition of sudden population movements away from the Black Sea coasts suggest that the basin was rapidly flooded through the Bosphorus sill 7150 years bp, causing a sea level rise of ~ 135 m in a few years (Ryan et al., 1997. As shown here, such a catastrophic redistribution of mass has significantly altered the amplitude of the Chandler wobble, the free motion of the pole of rotation around the main inertia axis of the Earth (Lambeck, 1980. We also estimate that during the flooding the pole of rotation was diverted from its secular path and shifted by ~ 30 m, at a rate of several meters per year. These rotational variations are found to be orders of magnitude larger than those produced by other short-term geophysical processes, such as earthquakes seismic moment release (O'Connell and Dziewonski, 1979; Chao et al.,1996, anthropogenic water impoundment (Chao, 1995, and tectonic mass movements (Alfonsi and Spada, 1998. The Black Sea flooding may thus be responsible for the most drastic change in the rotational parameters of the Earth in the recent history of our planet.

    The RAZOR (trademark) EX, a quantitative Polymerase Chain Reaction (qPCR) instrument, is a portable, ruggedized unit that was designed for the Department of Defense (DoD) with its reagent chemistries traceable to a Small Business Innovation Research (SBIR) contract beginning in 2002. The PCR instrument's primary function post 9/11 was to enable frontline soldiers and first responders to detect biological threat agents and bioterrorism activities in remote locations to include field environments. With its success for DoD, the instrument has also been employed by other governmental agencies including Department of Homeland Security (DHS). The RAZOR (Trademark) EX underwent stringent testing by the vendor, as well as through the DoD, and was certified in 2005. In addition, the RAZOR (trademark) EX passed DHS security sponsored Stakeholder Panel on Agent Detection Assays (SPADA) rigorous evaluation in 2011. The identification and quantitation of microbial pathogens is necessary both on the ground as well as during spaceflight to maintain the health of astronauts and to prevent biofouling of equipment. Currently, culture-based monitoring technology has been adequate for short-term spaceflight missions but may not be robust enough to meet the requirements for long-duration missions. During a NASA-sponsored workshop in 2011, it was determined that the more traditional culture-based method should be replaced or supplemented with more robust technologies. NASA scientists began investigating innovative molecular technologies for future space exploration and as a result, PCR was recommended. Shortly after, NASA sponsored market research in 2012 to identify and review current, commercial, cutting edge PCR technologies for potential applicability to spaceflight operations. Scientists identified and extensively evaluated three candidate technologies with the potential to function in microgravity.

    Full Text Available One important controversy connected with the effectiveness of grammar teaching seems to have been resolved as there is ample empirical evidence testifying to the positive effect of form-focused instruction on second language acquisition (Nassaji & Fotos, 2004; Norris & Ortega, 2000; Spada, 1997, 2010. Nevertheless, there are still a number of problems open to debate and awaiting concrete solutions, such as how to establish connections between form and meaning and find the best way to teach grammar for implicit knowledge, which, in the opinion of most SLA researchers (Ellis, 2006a, p. 95 and according to numerous theoretical positions, is a key driver of linguistic competence. One of the options available to language educators is to employ focused communication tasks, which “are designed to elicit production of a specific target feature in the context of performing a communicative task” (Ellis, 2001, p. 21. The aim of the study reported in this article was to explore the effect of focused communication tasks on the instructed acquisition of English past counterfactual conditionals when compared with contextualized practice activities. The results of two types of intervention were measured employing a number of data collection instruments with a view to tapping both the explicit and implicit knowledge of the participants of the study. Both types of instructional treatment were equally effective in helping learners develop the explicit knowledge of past unreal conditionals, but when it comes to the implicit knowledge of the aforementioned structure, the group instructed by means of focused communication tasks outperformed the other experimental group and the control group, as evidenced by the results obtained from the individually elicited imitation test and the focused communication task performed in pairs.

    Sugars are versatile molecules that play a variety of roles in the organism. For example, they are important in energy storage processes or as structural scaffolds. Here, we focus on the monosaccharide present in DNA by addressing the conformational and puckering properties in the gas phase of α- and β-methyl-2-deoxy-ribofuranoside and α- and β-methyl-2-deoxy-ribopiranoside. Other sugars have been previously studied in the gas phase The work presented here stems from a combination of chemical synthesis, ultrafast vaporization methods, supersonic expansions, microwave spectroscopy (both chirped-pulsed and Balle-Flygare cavity-based spectrometers) and NMR spectroscopy. Previous studies in the gas phase had been performed on 2-deoxyribose, but only piranose forms were detected. However, thanks to the combination of these techniques, we have isolated and characterized for the first time the conformational landscape of the sugar present in DNA in its biologically relevant furanose form. Our gas phase study serves as a probe of the conformational preferences of these biomolecules under isolation conditions. Thanks to the NMR experiments, we can characterize the favored conformations in solution and extract the role of the solvent in the structure and puckering of the monosaccharides. E. J. Cocinero, A.

    Full Text Available It has generally been argued that Persian does not include dummy elements called expletives, in spite of the existence of the morpheme ǐn which shows the behavior of an expletive in specific constructions. The morpheme is not a part of the argument structure and has no meaning. In Persian, which is a pro-drop language, the morpheme ǐn as expletive is generated only in [SPEC CP] of an independent clause. This element may occur in a subject position, object position, or as an object of a preposition. In subject and object positions it is optional when S′ moves to the end of the sentence, or is adjoined to it, in other cases it is obligatory. As an object of a preposition it is always obligatory, no matter whether the structure is the result of a movement or not. The aim of this article is to provide evidence in favor of the existence of expletives, and their projection in Persian.-----V jezikoslovju prevladuje miselnost, da perzijščina ne vsebuje mašil, navkljub obstoju morfema ǐn, ki v specifičnih strukturah izkazuje lastnosti mašila.

U savremenoj literaturi postoje pokušaji modeliranja pomenutog sistema u uslovima pravolinijskog kretanja, ali, do sada, nije definisan opšteprihvaćeni model vozača.

It should be mentioned that the problem is more complex with fact that a very complex motor and transmission behavior must be assumed in dynamic conditions. There are some attempts of modeling the driver and vehicle in the case of straight line driving, with a goal of tracking the given, frequently variable vehicle speed.

  12. Mobilization and attenuation of metals downstream from a base-metal mining site in the Matra Mountains, northeastern Hungary

    Regional geochemical baseline values have been established for Hungary by the use of low-density stream-sediment surveys of flood-plain deposits of large drainage basins and of the fine fraction of stream sediments. The baseline values and anomaly thresholds thus produced helped to evaluate the importance of high toxic element concentrations found in soils in a valley downstream of a polymetallic vein-type base-metal mine. Erosion of the mine dumps and flotation dump, losses of metals during filtering, storage and transportation, human neglects, and operational breakdowns, have all contributed to the contamination of a small catchment basin in a procession of releases of solid waste. The sulfide-rich waste material weathers to a yellow color; this layer of 'yellow sand' blankets a narrow strip of the floodplain of Toka Creek in the valley near the town of Gyongyosoroszi. Contamination was spread out in the valley by floods. Metals present in the yellow sand include Pb, As, Cd, Cu, Zn, and Sb. Exposure of the local population to these metals may occur through inhalation of airborne particulates or by ingestion of these metals that are taken up by crops grown in the valley. To evaluate the areal extent and depth of the contamination, active stream sediment, flood-plain deposits, lake or reservoir sediments, soils, and surface water were sampled along the erosion pathways downstream of the mine and dumps. The flood-plain profile was sampled in detail to see the vertical distribution of elements and to relate the metal concentrations to the sedimentation and contamination histories of the flood plain. Downward migration of mobile Zn and Cd from the contaminated upper layers under supergene conditions is observed, while vertical migration of Pb, As, Hg and Sb appears to be insignificant. Soil profiles of 137Cs which originated from above-ground atomic bomb tests and the Chernobyl accident, provide good evidence that the upper 30-40 cm of the flood-plain sections, which

    Study Objectives: The nuclear receptor REV-ERBα is a potent, constitutive transcriptional repressor critical for the regulation of key circadian and metabolic genes. Recently, REV-ERBα's involvement in learning, neurogenesis, mood, and dopamine turnover was demonstrated suggesting a specific role in central nervous system functioning. We have previously shown that the brain expression of several core clock genes, including Rev-erbα, is modulated by sleep loss. We here test the consequences of a loss of REV-ERBα on the homeostatic regulation of sleep. Methods: EEG/EMG signals were recorded in Rev-erbα knockout (KO) mice and their wild type (WT) littermates during baseline, sleep deprivation, and recovery. Cortical gene expression measurements after sleep deprivation were contrasted to baseline. Results: Although baseline sleep/wake duration was remarkably similar, KO mice showed an advance of the sleep/wake distribution relative to the light-dark cycle. After sleep onset in baseline and after sleep deprivation, both EEG delta power (1–4 Hz) and sleep consolidation were reduced in KO mice indicating a slower increase of homeostatic sleep need during wakefulness. This slower increase might relate to the smaller increase in theta and gamma power observed in the waking EEG prior to sleep onset under both conditions. Indeed, the increased theta activity during wakefulness predicted delta power in subsequent NREM sleep. Lack of Rev-erbα increased Bmal1, Npas2, Clock, and Fabp7 expression, confirming the direct regulation of these genes by REV-ERBα also in the brain. Conclusions: Our results add further proof to the notion that clock genes are involved in sleep homeostasis. Because accumulating evidence directly links REV-ERBα to dopamine signaling the altered homeostatic regulation of sleep reported here are discussed in that context.

Oral chemotherapy could be limited as a consequence of poor compliance and adherence, especially by elderly patients.Methods: We selected 30 cancer patients referred to our department and treated with oral therapy (capecitabine, vinorelbine, imatinib, sunitinib, sorafenib, temozolomide, ibandronate. This pilot study of oral therapy in the patient’s home was undertaken by a doctor and two nurses with experience in clinical oncology. The instruments used were clinical diaries recording home visits, hospital visits, need for caregiver support, and a questionnaire specially developed by the European Organization for Research and Treatment of Cancer (EORTC, known as the QLQ-C30 version 2.0, concerning the acceptability of oral treatment from the patient’s perspective.Results: This program decreased the need to access cancer facilities by 98.1%, promoted better quality of life for patients, as reflected in increased EORTC QLQ-C30 scores over time, allowing for greater adherence to oral treatment as a result of control of drug administration outside the hospital. This model has allowed treatment of patients with difficult access to care (elderly, disabled or otherwise needed caregivers that in the project represent the majority (78% of these.Conclusions: This model of active home care improves quality of life and adherence with oral therapy, reduces the need to visit the hospital, and consequently decreases the number of lost hours of work on

    Full Text Available Atmospheric sea salt particles affect chemical and physical processes in the atmosphere. These particles provide surface area for condensation and reaction of nitrogen, sulfur, and organic species and are a vehicle for the transport of these species. Additionally, HCl is released from sea salt. Hence, sea salt has a relevant impact on air quality, particularly in coastal regions with high anthropogenic emissions, such as the North Sea region. Therefore, the integration of sea salt emissions in modeling studies in these regions is necessary. However, it was found that sea salt concentrations are not represented with the necessary accuracy in some situations.In this study, three sea salt emission parameterizations depending on different combinations of wind speed, salinity, sea surface temperature, and wave data were implemented and compared: GO03 (Gong, 2003, SP13 (Spada et al., 2013, and OV14 (Ovadnevaite et al., 2014. The aim was to identify the parameterization that most accurately predicts the sea salt mass concentrations at different distances to the source regions. For this purpose, modeled particle sodium concentrations, sodium wet deposition, and aerosol optical depth were evaluated against measurements of these parameters. Each 2-month period in winter and summer 2008 were considered for this purpose. The shortness of these periods limits generalizability of the conclusions on other years.While the GO03 emissions yielded overestimations in the PM10 concentrations at coastal stations and underestimations of those at inland stations, OV14 emissions conversely led to underestimations at coastal stations and overestimations at inland stations. Because of the differently shaped particle size distributions of the GO03 and OV14 emission cases, the deposition velocity of the coarse particles differed between both cases which yielded this distinct behavior at inland and coastal stations. The PM10 concentrations produced by the SP13 emissions

  16. The MIT Program, Competition, and Ethics

    The MIT program in x-ray astronomy was, and still is, diverse and productive. Bruno Rossi and later George Clark, as the nominal leaders of the “x-ray astronomy group” created a “hands-off” culture wherein individual researchers could develop their own independent programs. Walter Lewin, Claude Canizares, and I as well as those in the next academic generations, e.g., Saul Rappaport and George Ricker, were able to thrive in this environment. MIT researchers were principal investigators or providers of x-ray instruments on sounding rockets and balloons in the 1960s and then in later years on nine satellite missions, OSO-7, SAS-3, HEAO-1, Einstein, ASCA, RXTE, Chandra, HETE-2, and Suzaku. Such a diverse program involved collaborations with other institutions and of course striving for primacy in discovery and competition for NASA resources. Looking back, I see a high degree of ethical behavior among the observational x-ray community during those years. In competition, we remembered that we might well be collaborating the following year and behaved accordingly. Many of us in the x-ray community had been friends since graduate school days and did not want to lose those relationships. Am I viewing the past through rose colored glasses? I think not. A vignette on this topic: In 1967, I was debating vigorously with Herb Gursky of AS&E about which institution, MIT or AS&E, should be the lead on the fourth paper (Oda et al. 1967, ApJ 148, L5) based on data from the 1966 AS&E rocket flight which had led to Allan Sandage’s (and Japanese) identification of Sco X-1 (Sandage, et al. 1966, ApJ. 146, 316). I and my Italian colleague, Gianfranco Spada, and our Japanese colleague, Minoru Oda, both then visiting MIT, had actively supported that flight. After one rather heated discussion with Herb about this, - I was the heated one; he always remained calm - he left my office saying: “Hale, however this comes out, let’s remain friends.” I treasured that comment and

    Full Text Available Najnowsze wymagania dotyczące budynków nisko i niemal zero energetycznych wymagają zastosowania odnawialnych źródeł energii w ramach budynku lub jego najbliższego otoczenia. Przedmiotem pracy jest analiza warunków pracy paneli fotowoltaicznych zamontowanych w systemie fasady wentylowanej. Przeanalizowano dwie fasady fotowoltaiczne, wschodnią i zachodnią, które zostały wkomponowane w elewację budynku znajdującego się w środowisku miejskim. Badane fasady stanowią zewnętrzną warstwę ścian eksperymentalnych zaprojektowanych dla budynków zero energetycznych. Obie ściany zostały zbudowane w ramach polsko-niemieckiego projektu GPEE na temat efektywności energetycznej budynków. Analiza została przeprowadzona dla danych pomiarowych uzyskanych z mierników prądu stałego, czujników temperatury umieszczonych na panelach i stacji meteorologicznej, w której rejestrowano między innymi temperaturę powietrza, kierunek i prędkość wiatru oraz promieniowanie słoneczne docierające zarówno na powierzchnię poziomą jak i pionową, wschodnią i zachodnią. Badania przeprowadzono dla wybranego tygodnia w maju, który charakteryzował się wysokim natężeniem promieniowania słonecznego i temperaturą powietrza utrzymującą się na poziomie około 20°C. Analizując otrzymane dane zaobserwowano, że działanie promieniowania bezpośredniego przy bezchmurnym nieboskłonie wpływa na wzrost temperatury paneli do ponad 60°C przy temperaturze powietrza nieprzekraczającej 20°C. Przy tak wysokiej temperaturze produktywność fasady fotowoltaicznej znacznie spada. Najwyższą moc chwilową zaobserwowano w pierwszej fazie operowania słońca na daną fasadę, przy wysokim natężeniu promieniowania i umiarkowanej temperaturze paneli fotowoltaicznych.

    Full Text Available U radu je prikazano delovanje sile prednaprezanja na armiranobetonski ram (u daljem tekstu AB ram. Posmatrani sistem je statički neodređen sa dva ukleštenja. Na njega deluje opterećenje prednaprezanje kablom silom Nk=600 kN, kao i sopstveno opterećenje. Visina rama je 6.00 m, a osovinski razmak 20.00 m. Opterećenje od sopstvene težine elemenata je od rigle i stuba. Opterećenje konstrukcije usled prednaprezanja spada u unutrašnja opterećenja, koja zamenjujemo ekvivalentnim opterećenjem koje predstavlja spoljašnje opterećenje. Proračun je izvršen metodom sila i metodom deformacija, kao i u softverskom programu 'Tower'. Metodom sila se uklanja ukleštenje i preseku se omogućava obrtanje. Statički neodređena veličina tada je moment ukleštenja. Kod metode deformacije sve statičke i deformacijske veličine izražavaju se putem izvesnog broja međusobno nezavisnih deformacijskih veličina, koje su određene iz uslova ravnoteže sistema. Broj nezavisnih deformacijskih neodređenih veličina predstavlja deformacijsku neodređenost nosača. Sve deformacijski neodređene veličine mogu se svrstati u dve grupe: prvu grupu čine uglovi obrtanja na krajevima kruto vezanih štapova, a drugu grupu komponente pomeranja čvorova. / The effects of prestressing forces on a reinforced concrete frame are shown in the paper. The structure is a statically indeterminate frame with two fixed supports. The load is due to tendon prestressing with Nk = 600 kN and due to self-weight of columns and beam. The columns height is 6.00 m and the beam span is 20.00 m. Effects of prestressing can be replaced by an external equivalent load. Calculations are performed by the force method, by the direct stiffness method and using the 'Tower' software. The rotational restraints are released at fixed supports and the restraint moments are calculated by the force method. The direct stiffness method uses the members' stiffness relations for computing member forces and

    ętościową i zmniejszają swoją gęstość właściwą. Największe zmiany wykazują skały iłowcowe, które mogą zwiększyć swoją gęstość objętościową ρο o ponad 20%, podczas gdy największy ubytek gęstości właściwej wykazują łupki ilaste i piaszczyste, których zmiana ρs wahała się od 0,88% do 5,93%, natomiast piaskowce zmniejszają swoją gęstość średnio o ok. 1,5%. Choć wydaje się logiczne, że wraz z wypalaniem się skał powinna wzrastać ich porowatość i jednocześnie zmieniać się gęstość objętościowa, badania nie wykazują ścisłej zależności pomiędzy oboma parametrami. Analiza granicznych wartości współczynnika przewodzenia ciepła skał karbońskich w temperaturach 20°C i 1000°C pokazuje, że wartości współczynnika λ po wygrzaniu skały ma tendencję odwrotnie proporcjonalną do wartości pierwotnej. Dla współczynnika przewodności cieplnej równego ok. 1 W/m·K w temperaturze pokojowej, po wygrzaniu skał do 1000°C jego wartości gwałtownie rosną do nawet 14 W/m·K. Wraz z większą początkową zdolnością do przewodzenia ciepła, wyprażenie skał w wysokiej temperaturze zaczyna przynosić skutek odwrotny w stosunku do jego przewodności cieplnej. Tendencja spadku przewodnictwa cieplnego dla skał osadowych jest zgodna z obserwacjami niemieckimi łupków i piaskowców, gdzie stwierdzono, że współczynnik λ dla temperatury pokojowej wynosi ok. 3,0-3,3 W/m·K, natomiast po ogrzaniu do temperatury 800°C jego wartość spada do ok. 1,4 W/m·K (Clauser & Huenges, 1995). Zauważalny jest także wyraźny logarytmiczny charakter zmian zdolności skał do przewodzenia ciepła przed i po wygrzewaniu ich w wysokich temperaturach. Współczynnik determinacji jest dla przebadanych próbek równy 0,70, co wobec niestabilności procesów termicznych w skałach i ich ścisłej zależności od składu mineralogicznego należy uznać za wyjątkowo wysoki. Wykonana analiza pokazuje, że nie można wykazać żadnej korelacji

    żowe zamiast płatów), aby powstający podczas frezowania urobek mógł spadać na spąg (Krauze, 2012b). Przykładowe rozwiązanie organu przestrzennego przedstawia fig. 3. Funkcję ładowania, realizowaną normalnie przez płaty, przejmują ładowarki. Rozdzielenie procesu ładowania od procesu frezowania jest jedną z najważniejszych zalet prezentowanego rozwiązania. Podczas pracy w ścianie parametry kinematyczne kombajnu mogą być zwiększane bez ryzyka wystąpienia problemów z ładowaniem na przenośnik, co obok możliwości ruchowych kombajnisty było głównym czynnikiem hamującym wzrost wydobycia. Załadunek urobku na przenośnik odbywa się za pomocą ładowarki, która po zmianie kierunku urabiania składa się, natomiast druga ustawiana jest w pozycji roboczej (Krauze, 2010). Kombajn porusza się tradycyjnie po rynnie przenośnika, jednak przy zastosowaniu cięgnowego systemu posuwu, który zrealizowany jest za pomocą napędów znajdujących się w chodnikach. Rozwiązanie takie umożliwia znaczne zmniejszenie gabarytów kombajnu dzięki usunięciu ciągników z kadłuba. Należy zaznaczyć, że w prezentowanym rozwiązaniu zakłada się zastosowanie pełnej automatyzacja pracy kombajnu i pozostałych maszyn ścianowych, co pozwala na urabianie calizny bez obecności załogi bezpośrednio w wyrobisku. Ma to duże znaczenie dla możliwości zwiększenia prędkości posuwu, szczególnie przy zakresie wysokości 1.0 m÷1.6 m. Przy wykorzystaniu znanych, z rozwiązań strugowych, systemów automatyki, sterowania i diagnostyki wprowadzenie automatyzacji procesu nie będzie stanowiło znaczącego problemu. W proponowanym rozwiązaniu kombajn ma możliwość wyjechania do chodnika na tyle, aby możliwe było zrealizowanie przekładki jak w przypadku strugów. Uzyskuje się wtedy krótki czas przekładki, który w skrajnym przypadku może zmieścić się w tzw. czasie organizacyjnym ściany. Ponadto urabianie odbywa się pełnym zabiorem na całej długości

    sprawność ładowania ηl. Uzyskane wyniki i ich analiza pozwoliły stwierdzić, że badane organy wykazywały bardzo zróżnicowane sprawności ładowania, w zależności od zmiennych parametrów ruchowych, czyli prędkości posuwu vp i obrotów n, a także przy różnym kącie nawinięcia płata ślimaka. Również istotnym wnioskiem z badań, który może w praktyce zostać wykorzystany, jest fakt, że dla stałych obrotów organu n i zwiększanej prędkości posuwu vp spadała sprawność ładowania ηł (dla pracy organu bez ładowarki). Fakt ten jest ważny, ponieważ w warunkach dołowych w trakcie eksploatacji kombajnu ścianowego istnieje tylko możliwość regulacji jego prędkości posuwu. Istotnym dla wykorzystania w praktyce, może być również fakt, iż przy pracy organu z ładowarką występuje wzrost poboru mocy organu przy wzroście współczynnika wypełnienia kw. Jest to istotne z punktu widzenia ekonomi eksploatacji i dążenia do minimalnego zużycia energii. Zrealizowane badania laboratoryjne sprawności procesu ładowania, pozwoliły uzyskać szeroki zakres wyników, które mogą pomóc przy doborze parametrów ruchowych kombajnu ścianowego w trakcie jego eksploatacji, a nawet wcześniej, na etapie projektowania organów ślimakowych (Wydro, 2011).
