description: Tef (Eragrostis tef (Zucc.), Trotter: Poaceae) is a staple food crop of Ethiopia where it is originated and diversified. Red tef worm (Mentaxya ignicollis) is a serious pest of tef grown on clay soils. Hence the present study emphasized on the evaluation of insect growth regulators to control Red Tef Worm. Laboratory study were carried out in completely randomized design with two insect growth regulators (lufenuron at doses 20, 40 and 60g a.i/ha and teflubenzuron at doses of 75, 112.5 and 150g a.i./ha) against 3rd instar larvae of RTW. The green house study was carried out in randomized complete block design with the two Chitin synthesize Inhibitors (CSIs) (lufenuron at dose of 40g a.i./ha and teflubenzuron at dose of 112.5g a.i./ha). Efficacy of CSIs in affecting the hatchablity of the eggs was also studied. From the laboratory and greenhouse experiments the IGRs, lufenuron and teflubenzuron, caused mortality after affecting the developmental stage of RTW larvae and also inhibited egg hatchability. In general, lefenuron (40g a.i./ha) was found to be effective and and showed high potency against 3rd instar larvae of RTW under laboratory and greenhouse conditions. Since the CSIs are safe to the environment and other beneficial organisms, it is recommended to be verified for usage under open and large field conditions for the control of RTW.

description: We classify the possible shapes of minimal free resolutions over a regular local ring. This illustrates the existence of free resolutions whose Betti numbers behave in surprisingly pathological ways. We also give an asymptotic characterization of the possible shapes of minimal free resolutions over hypersurface rings. Our key new technique uses asymptotic arguments to study formal Q-Betti sequences.

description: Le domande cui la presente ricerca tenta di rispondere sono le seguenti: in che misura un testo autobiografico come le Memorie di Lorenzo Da Ponte può diventare una risorsa didattica e pedagogica per insegnare a scrivere di sé? In che misura studenti di I media possono essere sollecitati a mettersi in gioco e a raccontarsi a partire dal modello letterario (e dal genere) in esame? Per rispondere alle domande che la ricerca si pone, si è deciso di seguire le seguenti fasi di lavoro: lettura ed esplorazione di pagine delle Memorie opportunamente scelte; analisi dei testi proposti, finalizzata all’individuazione e alla comprensione di alcuni elementi chiave del genere autobiografico (grammaticali e linguistici, ma anche stilistici e narrativi); rielaborazione dei modelli proposti (e degli elementi in essi valorizzati) tramite la “ri-scrittura” da parte degli studenti. Le varie fasi del lavoro hanno dimostrato che la scrittura autobiografica, e, nella fattispecie, pagine opportunamente selezionate delle Memorie, costituiscono una potente ed efficace risorsa didattica e pedagogica, anche nei riguardi di studenti particolarmente giovani quali quelli di prima media.

description: The present study was undertaken to assess the effect of feeding field pea (Pisum sativum L.) and grass pea (Lathyrus sativa L.) hulls at different levels of inclusion in concentrate mixture on nutrient intake, digestibility and milk yield of dairy cows. Thirty lactating Jersey cows with similar range of body weight, body condition and first stage of lactation were selected from the herd maintained at Adaberga Research Station, West Shoa Administrative Zone, Oromia Regional State, Ethiopia. Animals were blocked based on parity and milk yield under Complete Randomized Block Design (CRBD) and were assigned to each treatment randomly. Five dietary treatments were: T1 (control), maintained on native hay + concentrate mixture formulated with only conventional feed ingredients (0% pulse hulls); T2, T3, T4 and T5 were maintained on native hay + concentrate mixtures formulated with inclusive of 35% field pea hull, 50% field pea hull, 35% grass pea hull and 50% grass pea hull, respectively. Animals were fed native hay ad lib while concentrate mixtures were fed @ 2kg for maintenance requirement and 1kg for each 2.5 kg of milk yield individually both in the morning and afternoon for a period of 180 days. Data were analysed using SAS software packages and Turkey's HSD multiple comparison technique was used for means separation. Results of the study revealed that the average DM, OM and CP intake during the whole experimental period (kg/h/d) were higher (P<0.01) as a result of feeding 35 and 50% field pea hulls and 35% grass pea hulls in concentrate mixtures (T2, T3 and T4, respectively) as compared to the control while feeding of 50% grass pea hull in concentrate mixture (T5) had no effect on DM, OM and CP intake. The NDF and ADF intake (kg/h/d) were higher (P< 0.001) in all treatment groups which were fed field pea and grass pea hulls at different levels of inclusion in concentrate mixture as compared to the control group. Digested DM was higher (P<0.01) in feeding of 35% field pea hull (T2) and digested CP was higher (P<0.01) as a result of feeding 35 % field pea and grass pea hulls in concentrate mixture (T2 and T4) than the control. Digested NDF and ADF intake were also higher (P<0.01) in T2, T3 and T4 than the control. Digestibility of CP was significantly higher (P< 0.01) in T2, T3 and T4 than the control while digestibility of NDF was higher (P< 0.01) in T2 than the control. Milk production was higher (P<0.01) as a result of feeding 35% field pea and grass pea hulls in concentrate mixture (T2 and T4) than the control. Therefore, it is concluded that alternative concentrate mixtures could be formulated by inclusion of 35% field pea and grass pea hulls in the ration of dairy cows.

Emotional lability as a symptom of extra-axial posterior fossa tumours : a case-control review of neuroanatomy and patient-reported quality of life
Creators: name: Prakash, Swetha
Publisher: name: University of British Columbia
Year: 2020

description: Introduction: Emotional lability (EL), the uncontrollable and unmotivated expression of emotion, is a rare and distressing symptom of brainstem compression from extra-axial posterior fossa tumours. In published case reports, EL is alleviated by surgical resection of the tumour. The primary goal of this study was to radiographically compare the degree of compression from mass lesions onto brainstem structures between EL cases and matched controls. The secondary goal was to compare changes in patient reported quality of life (QOL) pre- and post-operatively. Methods: In a retrospective review of patients treated for posterior fossa tumours with brainstem compression between 2002 and 2018 at Vancouver General Hospital, 11 patients with confirmed EL were identified. Each case was matched to 3 controls. Pre-operative axial T2-weighted FLAIR MRI scans were reviewed, and a lateral brainstem compression scale was used to characterize the degree of mass effect at the level of the medulla, pons, and midbrain. Compression was compared between EL patients and control patients. Clinical variables were also compared. Patients routinely complete the Short form-36 (SF36v1) general health survey at clinic appointments, these surveys were retrospectively obtained from patient charts. Pre- versus post-operative changes in survey scores were compared between EL patients and controls. Results: EL symptoms ceased post-operatively for all EL patients. EL tumours exert greater compression onto the pons (EL mean compression score=2.91, control mean compression score=1.91, one-tailed p=0.03). EL patients more commonly have cerebellar findings (p=0.003) pre-operatively. Patients with EL-causing tumours experienced greater improvement post-operatively in “Health Change” (two-tailed p=0.05), which was maintained over time. Control patients experienced greater improvement in the “Role Limitations Due to Physical Health” SF36v1 sub-score (two-tailed p=0.03), which was not maintained over time. Conclusion: This is the largest case series to-date investigating adult extra-axial posterior fossa tumours that cause EL. Findings suggest that compression onto the pons inhibits control over involuntary, stereotyped expression of emotion This adds to evidence that EL may be attributed to deafferentation of the cerebellum from cortical and limbic structures through the basis pontis, leading to impaired modulation of emotional response. The QOL results augment benefits of obtaining EL-alleviating surgery.
Asymptotic behavior of Aldous' gossip process

description: Aldous [(2007) Preprint] defined a gossip process in which space is a discrete $N\times N$ torus, and the state of the process at time $t$ is the set of individuals who know the information. Information spreads from a site to its nearest neighbors at rate 1/4 each and at rate $N^{-α}$ to a site chosen at random from the torus. We will be interested in the case in which $α<3$, where the long range transmission significantly accelerates the time at which everyone knows the information. We prove three results that precisely describe the spread of information in a slightly simplified model on the real torus. The time until everyone knows the information is asymptotically $T=(2-2α/3)N^{α/3}\log N$. If $ρ_s$ is the fraction of the population who know the information at time $s$ and $\varepsilon$ is small then, for large $N$, the time until $ρ_s$ reaches $\varepsilon$ is $T(\varepsilon)\approx T+N^{α/3}\log (3\varepsilon /M)$, where $M$ is a random variable determined by the early spread of the information. The value of $ρ_s$ at time $s=T(1/3)+tN^{α/3}$ is almost a deterministic function $h(t)$ which satisfies an odd looking integro-differential equation. The last result confirms a heuristic calculation of Aldous.

description: We develop a general approach for studying the cumulative probability distribution function of localized objects (particles) whose dynamics is governed by the first-order Langevin equation driven by superheavy-tailed noise. Solving the corresponding Fokker-Planck equation, we show that due to this noise the distribution function can be divided into two different parts describing the surviving and absorbing states of particles. These states and the role of superheavy-tailed noise are studied in detail using the theory of slowly varying functions.

description: We have studied electron scattering by out-of-plane (flexural) phonon modes in doped suspended graphene and its effect on charge transport. In the free-standing case (absence of strain) the flexural branch shows a quadratic dispersion relation, which becomes linear at long wavelength when the sample is under tension due to the rotation symmetry breaking. In the non-strained case, scattering by flexural phonons is the main limitation to electron mobility. This picture changes drastically when strains above $\bar{u}=10^{-4} n(10^{12}\,\text{cm}^{-2})$ are considered. Here we study in particular the case of back gate induced strain, and apply our theoretical findings to recent experiments in suspended graphene.

description: Since the discovery of graphene in 2004, numerous other materials with intriguing electronic, optical, and magnetic properties have been found to be layered and exfoliatable down to atomic thickness. Owing to their weak interlayer coupling, mediated only by van der Waals forces, this new class of 2-dimensional materials, also known as van der Waals (vdW) materials, allows layer-by-layer stacking, overcoming some of the limitations of growth techniques. In particular, the growing inventory of vdW materials has expanded to include magnetic materials, further broadening the possibilities of novel devices based on stacked heterostructures. These magnetic heterostructures can find applications in spintronics and memory devices and may be combined with other vdW materials with optical properties for applications in optoelectronics. In this thesis, we assembled heterostructures via mechanical transfer or growth to modify the magnetism in these vdW materials. We used various optical and electrical techniques to probe the modified magnetism or its effects on the novel heterostructure. Thus, we observed the emergence of the magnetic proximity effect on the topological insulator BiSbTeSe2 after dry transferring a thin flake of Cr2Ge2Te6 on top, taking steps towards the observation of novel topological phases, such as the quantum Hall insulator. Additionally, we demonstrated an increased Curie temperature and magnetic anisotropy, effectively enhancing the magnetism, in thin flakes of Cr2Ge2Te6 and Cr2Si2Te6 after sputtering NiO or MgO. Finally, noting that the effect of modified magnetism in Cr2Ge2Te6 after sputtering NiO or MgO is induced due to wrinkle formation and strain, we further reproduce similar wrinkle formation on other 2D materials such as hBN, graphite, and 2D antiferromagnets (XPS3, (X= Mn, Fe, Ni), CrSBr, RuCl3). We used polarized Raman spectroscopy to characterize the induced biaxial strain in hBN and showed that such wrinkle formation can lead to moderately (up to 1.4% strain) spatially inhomogeneous and anisotropic strain profiles. These efforts demonstrate the versatility of tailoring the properties of these vdW materials.

description: Im seit 2006 an der Universität Bremen angebotenen Förderunterricht für Kinder und Jugendliche, deren Erstsprache nicht oder nicht nur Deutsch ist, verbessern nicht nur Schüler_innen ihre schulischen Kompetenzen: Unter fachlicher Anleitung haben inzwischen mehr als 260 Studierende –insbesondere angehende Lehrkräfte– das eigenständige Unterrichten in kleinen Schüler_innengruppen gelernt und geübt. Durch die Mitarbeit im Förderprojekt sollen sie insbesondere ein Verständnis für sprachsensiblen Unterricht wie auch migrationsgesellschaftliche Bedingungen entwickelt haben sowie eigenes Denken und Handeln reflektieren können. Diese Studie untersucht erstmalig die langfristigen Effekte dieses Projekts als Praxisteil einer migrationssensiblen Lehramtsausbildung auf das pädagogische Können von Lehrkräften. Mithilfe eines online-Fragebogens zum Thema Migration und Bildung wurden von Mai-August 2016 ehemalige Förderlehrkräfte befragt, die inzwischen als Lehrkräfte in Schulen tätig sind (Experimentalgruppe), sowie Lehrkräfte mit vergleichbaren Merkmalen, die in ihrem Studium nicht an einer solchen Maßnahme teilgenommen haben (Kontrollgruppe). Die quantitative und qualitative Auswertung weist bedeutsame Unterschiede zwischen den Vergleichsgruppen aus, die sich sowohl auf der Kenntnisebene als auch auf der Fähigkeiten-/Handlungsebene niederschlagen: Im Vergleich zur Kontrollgruppe haben sich die ehemaligen Förderlehrkräfte deutlich mehr mit migrationsgesellschaftlichen Themen auseinandergesetzt;sie fühlen sich besser auf das Unterrichten in mehrsprachigen Klassen vorbereitet und beziehen häufiger Sprachen und Migrationserfahrungen von Schüler_innen in den Fachunterricht mit ein. In beiden Gruppen wurde der Wunsch nach einer stärker praxisorientierten Lehramtsausbildung geäußert und die Theorielastigkeit der universitären Ausbildung beklagt. Die Studie zeigt nicht nur, dass die konkrete angeleitete Praxiserfahrung an der Universität Bremen auch nach dem Übergang an die Schule eine hohe Wertschätzung erfährt, sondern auch, dass Universitäten generell die Herausforderung, den Sinn theoretischer Kenntnisse für die schulische Alltagspraxis zu verdeutlichen, noch nicht durchgehend meistern.

description: We analyze decay processes of the inflaton field, phi, during the coherent oscillation phase after inflation in f(phi)R gravity. It is inevitable that the inflaton decays gravitationally into gauge fields in the presence of f(phi)R coupling. We show a concrete calculation of the rate that the inflaton field decays into a pair of gauge fields via the trace anomaly. Comparing this new decay channel via the anomaly with the channels from the tree-level analysis, we find that the branching ratio crucially depends on masses and the internal multiplicities (flavor quantum number) of decay product particles. While the inflaton decays exclusively into light fields, heavy fields still play a role in quantum loops. We argue that this process in principle allows us to constrain the effects of arbitrary heavy particles in the reheating. We also apply our analysis to Higgs inflation, and find that the gravitational decay rate would never exceed gauge interaction decay rates if quantum gravity is unimportant.

description: This thesis describes extensions of goal-oriented methods for a posteriori error estimation and control of numerical approximation to a class of highly-nonlinear problems in computational solid mechanics. An updated Lagrangian formulation formulation of the dynamic, large-deformation response of structures composed of strain-rate-sensitive elastomers and elastoplastic materials is developed. To apply the theory of goal-oriented error estimation, a backward-in-time dual formulation of these problems is derived, and residual error estimators for meaningful quantities of interest are established. The target problem class is that of axisymmetric deformations of layered elastomer-reinforced shells-of-revolution subjected to shock loading. Extensive numerical results on solutions of representative problems are given. It is shown that extensions of the theory of goal-oriented error estimation can be developed and applied effectively to a class of highly-nonlinear, multi-physics problems in solid and structural mechanics

description: Yearling sheep from highland (Arsi-Bale) and lowland (Black Head Ogaden) areas of Ethiopia were used to determine effects and interactions of breed and length of feeding period on mutton pH and color. Rams were purchased, transported, and handled in accordance with normal practices of abattoirs in Modjo Modern Export Abattoir. 18-20 sheep of each origin were subjected to feeding periods 2, 4, and 6 weeks in length, during which time grass hay was consumed ad libitum and concentrate supplement was provided at approximately 200 g/day per animal (DM basis). Mutton pH and color measurements were made at 45 min (day 0) and 1, 2, and 3 days post-slaughter, with storage at 4°C. The data were analyzed using the GLM of SAS. Average mutton pH of Arsi-Bale rams was similar to Black head Ogaden rams on the same day of post slaughters. Both linear and quadratic length of feeding period had significant influence in mutton pH on day 0, 1, 2, and 3 post slaughters (P < 0.05). Length of feeding periods had greater effect to reduce mutton pH. For both sheep breeds, mutton pH values were lowest among feeding period lengths for 6 weeks. Mutton pH decreased as post slaughter days increased, but considerably decreased between day 0 and 1 post slaughters and then after slightly decreased as post slaughter days increased. The average mutton lightness (L*) was greater (P < 0.05) for Black head Ogaden rams (L*=29.50, 39.68, 40.91 and 42.73) than Arsi-Bale rams (L*=27.89, 35.81, 36.67 and 38.04) on the same day of 0, 1, 2, and 3 day post slaughters, respectively. Mutton a* (as an index of redness) changed with increasing day post-slaughter. The results of this study revealed that mutton darkening of both sheep origins was not detected/ apparent from comparisons of mutton pH and color measures with values reported in different literatures.

description: Comparison results are obtained for the inclusion probabilities in some unequal probability sampling plans without replacement. For either successive sampling or Hájek's rejective sampling, the larger the sample size, the more uniform the inclusion probabilities in the sense of majorization. In particular, the inclusion probabilities are more uniform than the drawing probabilities. For the same sample size, and given the same set of drawing probabilities, the inclusion probabilities are more uniform for rejective sampling than for successive sampling. This last result confirms a conjecture of Hájek (Sampling from a Finite Population (1981) Dekker). Results are also presented in terms of the Kullback--Leibler divergence, showing that the inclusion probabilities for successive sampling are more proportional to the drawing probabilities.

description: Inappropriate farming system and utilization of natural resources are among the major causes for the current land degradation in Ethiopia. To control soil erosion cheap, replicable and sustainable conservation measures need to be implemented. The use of vetiver grass (Vetiveria zizanioides L.) makes a better option for soil erosion and sediment control and nutrient trapping in a wide range of environments. This study was undertaken to investigate the effects of using vetiver grass in improving soil fertility and productivity through nutrient trapping. The study was conducted at Anno agro-industry where vetivar grass was being used for soil conservation purpose for more than one and half decade. Sample top soils (0-30 cm) from with and without vetiver grass adjacent area were collected in six replicates and important soil parameters such as bulk density, moisture content, CEC, soil organic matter, total nitrogen, available phosphorous and available potassium were determined. The study also involved growing maize crop for two months in plastic pots filled with soil sample from with and without vetiver to compare their productivity. Plant growth parameters such as days to emergence, plant height, leaf length, leaf numbers per plant, root and shoot dry and fresh weights and root to shoot ratio were used to evaluate the difference in the productivity of with and without vetiver grass soil. Soil bulk density, CEC, Organic Matter, Total Nitrogen, Available Phosphorous, and Potassium contents, were significantly higher for soil with vetiver than for without vetiver grass soil. The results revealed that the use of vetiver grass as a soil conservation practice improved soil fertility and productivity.

description: Questo elaborato tratta l’entrata nel linguaggio scritto attraverso la proposta di un percorso di insegnamento-apprendimento che stimoli il passaggio dall’alfabetizzazione emergente all’alfabetizzazione formalizzata, rivolto agli allievi della scuola dell’infanzia. Nello specifico si intendeva verificare se le situazioni problema proposte permettessero ai bambini di sviluppare maggiore consapevolezza e motivazione nei confronti dell’apprendimento della lingua scritta. La ricerca è stata condotta somministrando un’intervista volta a indagare le rappresentazioni dei bambini sulla funzionalità della lingua scritta e sulle modalità di apprendimento della lettura. Inoltre gli allievi sono stati chiamati a elaborare una produzione scritta. L’intervista è stata proposta al gruppo campione prima e dopo il percorso di apprendimento. Contemporaneamente è stata somministrata a un gruppo di controllo che non ha partecipato alla sperimentazione delle situazioni problema. Tutto ciò era volto a favorire un’analisi dei dati che permettesse di istituire un confronto tra i due gruppi d’indagine, evidenziando eventuali similitudini e divergenze. I risultati ottenuti mostrano come i soggetti che hanno avuto la possibilità di familiarizzare con la lingua scritta evidenziano una forte motivazione all’apprendimento e appaiono disinibiti nel formulare ipotesi, fornire spiegazioni in merito alla funzionalità dello scritto e sperimentare serenamente l’utilizzo del codice.

description: We derive the evolution of the infrared (IR) luminosity function (LF) over the last 4/5ths of cosmic time, using deep 24um and 70um imaging of the GOODS North and South fields. We use an extraction technique based on prior source positions at shorter wavelengths to build the 24 and 70um source catalogs. The majority (93%) of the sources have a spectroscopic (39%) or a photometric redshift (54%) and, in our redshift range of interest (i.e., 1.3

description: Red tef worm (M. ignicollis) is a serious pest of tef (Eragrostics tef (Zucc.), Trotter: Poaceae) grown on black soils. Hence the present study was conducted to identify the effective isolate and conidial concentration of the entomopathogenic fungi (Beauveria bassiana and Metarhizium anisopliea isolates) and to measure the larval mortality of M. ignicollis caused by the entomopathogenic fungi and, thereby controlling RTW to increase the production of tef on black soils. Laboratory studies were carried out in completely randomized design of with four fungal isolates at four conidial concentrations against 3rd instar larvae of red tef worm. The green house study were carried out in randomized complete block design with the four isolates at the concentration of 1x109 spores/ml. Percent mortality increased from 46.67 to 83.33% and 43.33 to 73.33% when larvae were treated with M. anisopliae isolate, MM and PPRC-2, respectively, whereas, B. bassiana isolates PPRC-56 and PPRC-9609 caused mortality ranging from 43.33 to 66.67% and 43.33 to 50%, respectively when applied at the conidial concentration of 1x106 to 1x109spores/ml under laboratory condition. Percent mortality under greenhouse condition showed that MM (70%) was the most virulent isolate; however, PPRC-2, PPRC-56 and PPRC-9609 caused larval mortality of 60%, 53.33% and 46.67% respectively. It was concluded that all tested isolates can cause infection on 3rd instar larvae of red tef worm and able to cause delayed effect to the next stages after application; however, in both laboratory and greenhouse studies, isolate MM was the most effective at conidial concentration of 1x109 spores/ml. In general, MM (1x109spores/ml) isolate was found to be effective and potency against 3rd instar larvae of red tef worm under laboratory and greenhouse conditions. Therefore, since this agent is safe to the environment and other beneficial organisms and it is recommended to be verified for usage under open and large field conditions for the control of red tef worm.

Environmental financial assurance : current coverage, institutional challenges, and alternative financial guarantee arrangements

description: Mining activities provide comprehensive socio-economic benefits to a nation. There are, however, varying degrees of environmental risks and financial liabilities related to mining. Governments expect mine operators to rehabilitate the environmental condition of disturbed lands once they complete their extraction activities. In the event of insolvency or bankruptcy, regulators also require them to establish that they possess adequate, financial assurance to ensure that mandatory reclamation and closure requirements are performed in accordance with the approved mine closure plans before initiating their mine operations. Such an approved ‘hard’ financial assurance instrument is typically held by the government or in trust by a third-party in escrow until the end of mining and only released when closure and reclamation operations are completed, which in some cases could be decades into the future or sometimes never. Financing these obligations come with a set of other challenges. Requiring a mining company facing both financial difficulties and unsettling market conditions, an epidemic of current times, to take on tens of millions or even hundreds of millions of dollars in ‘hard’ financial liabilities only increases the possibility of its financial collapse and potential reclamation failure. The dissertation focuses on the evaluation of a proposed structured finance mechanism that is expected to offer greater access to required funds from the capital markets and one that aims to assist government regulators with their regulatory compliance, oversight, and enforcement efforts. Even though securitisation has demonstrated the ability to take an illiquid asset or group of such assets, and through financial engineering, transforming it into a marketable financial security for sophisticated investors to invest in, it has yet to be applied to the securitisation of financial assurance requirements. The available financial assurance funding tools and options are also assessed. The dissertation is expected to deepen the discussion surrounding seeking more effective and readily accessible environmental financial assurance instrument solutions for the resource extractive industries. No literature evidence seems to exist to support any earlier study on the prospect of such a financial assurance-backed securitised mechanism. It is therefore of interest to investigate its potential.

description: In questo progetto si va a realizzare un prototipo di submeter intelligente utilizzabile ad esempio in una palazzina in cui vi è un Master centrale e almento due slave corrispondenti agli appartamenti della palazzina che comunicano tra di loro per mezzo del protocollo modbus, tipico di queste applicazioni. I vari slave si occupano della misurazione di alcuni parametri fondamentali tra cui corrente, tensione, potenza, cosphi e di inviare queste info al master che le processa e le inserisce in un database. Quest’ultimo sarà poi utilizzato da un editor grafico per visualizzare i parametri su una pagina web e tenere monitorato a proprio piacimento tutto quello che succede. Il Master possiede un piccolo Oled in grado di visualizzare instantaneamente le misure effettuate e tramite un pulsante di switchare la visualizzazione di tali. Da lato slave vi è un rtc in grado di mantenere l’orario del dispositivo anche in assenza di alimentazione. Il sistema Modbus è testato sia in modalità half-duplex per il primo slave, sia in modalità full duplex per il secondo slave per dimostrare i possibili casi di funzionamento.

description: A natural and intrinsic characterization of the structure of the set $\mathfrak{C}$ of positive unital maps is given, i.e. it is shown that $\mathfrak{C}$ is isometrically isomorphic to the subset $\gD$ of bp-positive density matrices endowed with the geometry given by the norm $α$ dual to the Grothendieck projective norm $π$, the structure of $\gD$ is determined by the set of its exposed points, and finally a characterization of exposed points of $\gD$ in terms of convex analysis is presented. This seems to be an answer to an old open problem, characterization of the structure of the set of positive maps, studied both in Quantum Information and Operator Algebras. Our arguments are based on the concept of exposed points and links between tensor products and mapping spaces. It should be emphasized that the concept of exposed point depends strongly on the geometry, hence the role of the norm $α$ is crucial.

description: Questo lavoro di ricerca è stato progettato al fine di osservare se la valorizzazione delle identità competenti dei bambini tendenzialmente esclusi dal gruppo permette di cambiare le dinamiche relazionali in sezione favorendo la loro inclusione. Dedicando del tempo a tre allievi, bisognosi di uno sguardo inclusivo, è stato possibile individuare le loro identità competenti, valorizzarle e offrirle ai compagni. Tutte le attività svolte sono state collegate al tema della sezione: gli indiani del Nord America. I dati che ho raccolto sono di tipo qualitativo, infatti, sono stati considerati il diario di bordo e le interviste fatte alla mia dpp e alla docente d’appoggio. Da questa ricerca, svolta nella SI di Personico, emerge che la valorizzazione delle identità competenti, attraverso delle attività o degli angoli può influire in modo positivo sulle dinamiche relazionali della sezione. Grazie al percorso svolto insieme a me e al progetto che stanno portando avanti la mia dpp e la docente d’appoggio, si può osservare che questi tre allievi sono più desiderosi di relazionarsi con i propri compagni. Inoltre risulta che se i bambini si conoscono meglio imparano a guardarsi con occhi diversi e a capire che tutti, anche i compagni che di primo acchito sembra portino con sé solamente cose negative, sono bravi a fare qualcosa e possono offrire le loro identità competenti a tutto il gruppo.

description: Bean anthracnose, caused by Colletotricum lindemuthianum (Sacc. & Magn.) is an important disease affecting common bean (Phaseolus vulgaris L.). Information on yield losses and management options addressing both seed and soil-borne inoculum sources of this disease is lacking in Hararghe highlands which produces common bean in large areas. The present study was undertaken to evaluate the effect of integrated management of bean anthracnose through soil solarization and fungicide applications on disease development, seed health and seed yield of common bean variety Mexican-142. Field experiments were conducted at Haramaya University main campus and Hirna Research Sub-Station in 2010 main cropping season. Soil solarization was integrated with mancozeb and carbendazim seed treatments, with foliar sprays of carbendazim at the rate of 0.5 kg/ha at 10 and 20 days intervals. The experiment was arranged in 2 x 3 x 3 split-split plot design with three replications. A total of 18 treatments were evaluated. There was significant difference in the anthracnose incidence, severity, infected pods per plant, infected seeds and AUDPC among treatments. Combined effect of mancozeb seed treatment with carbendazim spray at 10 day intervals and carbendazim seed treatment and carbendazim spray at 10 day intervals have reduced severity by 46.5% and 41%, respectively at Haramaya. Interactions of solarized soil with carbendazim foliar spray frequencies at 10 days interval reduced the number of infected pods per plant by 58% at Haramaya and 38.9% at Hirna. Seed treatments, foliar sprays and soil solarization alone as well as their interactions did not significantly affect pods per plant and seeds per pod at both locations. The combinations of solarized soil + mancozeb seed treatment + carbendazim foliar spray at 10 day intervals produced seed yield of 3.8 t h-1 at Haramaya and 3.6 t h-1 at Hirna over the control. In the results concluded that, the integration of soil solarization, seed treatments and foliar spray were found to be effective in reducing bean anthracnose epidemics and increasing yield. Extensive studies are recommended for detection of seed health and management options to enhance high quality of common bean production in these regions.

description: We present spectra of 32 previously unpublished confirmed and candidate Wolf-Rayet ([WR]) and weak emission-line (WELS) central stars of planetary nebulae (CSPNe). Eighteen stars have been discovered in the Macquarie/AAO/Strasbourg H-Alpha (MASH) PN survey sample, and we have also uncovered 14 confirmed and candidate [WR]s and WELS among the CSPNe of previously known PNe. Spectral classifications have been undertaken using both the Acker & Neiner and Crowther, De Marco & Barlow schemes. Twenty-two members in this sample are identified as probable [WR]s; the remaining 10 appear to be WELS. Observations undertaken as part of the MASH spectroscopic survey have now increased the number of known [WR]s by ~30 per cent. This will permit a better analysis of [WR] subclass distribution, metallicity effects, and evolutionary sequences in these uncommon objects.
