description: Σκοπός της παρούσης εργασίας είναι να παρουσιάσει την πολυσχιδή προσωπικότητα του Παχώμιου Ρουσάνου, να εκθέσει στοιχεία της σύντομης ζωής του και να τον αναδείξει ως έναν διδάσκαλο του γένους. Στο πρώτο κεφάλαιο γίνεται μια μικρή περιήγηση στα του βίου του, καταγράφεται η πολεμική χροιά της θεολογικής του παρουσίας στα δεδομένα της χρονικής περιόδου που ζει· τονίζεται ο νηπτικός του χαρακτήρας, που θα επηρεάσει το σύνολο της ζωής του, του κηρύγματός του και γενικότερα του ιεραποστολικού του έργου. Στο δεύτερο κεφάλαιο τονίζεται η συνεισφορά του στην παιδεία και καταγράφονται τα έργα του. Στο τρίτο κεφάλαιο έγινε προσπάθεια να διαφανεί μέσα από τα συγγράμματα του προσφιλούς μοναχού, το διδασκαλικό του ένστικτο, η διορατικότητά του στο χώρο της παιδείας και οι διδακτικές μέθοδοι που ακολούθησε στη σύντομη αλλά μεστή παρουσία του στη Λειμωνιάδα σχολή. Προσπάθεια ιδιαίτερη έγινε στην απόδοση της παραλληλίας κάποιων απόψεών του μ’ αυτές του Κοραή ώστε να τονισθεί περαιτέρω η σπουδαιότητα του έργου του και να παρουσιαστεί ο ίδιος εν είδει πρόδρομός του.
description: The purpose of this paper is to present the pluralistic personality of Pachomios Rousanos, to expose elements of his short life and to point him out as a teacher of the nation. In the first chapter there is a small presentation of his life, the martial complexion of his theological presence is recorded from the data of the era he lives in; his prudent character which will affect his whole life, his preaching and generally his missionary work is emphasized. In the second chapter his contribution to education is pointed out and his works are written down. In the third chapter it is attempted to show through the writings of the beloved monk, his teaching instinct, his insight into the field of education, and the teaching methods that he followed in his brief but regular presence at the Leimoniada School. Particular effort was made in rendering the parallels of some of his views with those of Korai’s to further emphasize the importance of his work and to present himself as Korai’s forerunner.

description: The aim of the present thesis was the study of bans and registered acts in the land register. We examined the issues of the interim order in the common provisions and the difficult and very practical issue of the interim injunctions issued under Law 3869/2010. Further reference is made to the inaccurate object of the confiscation of criminal law, which also has implications for civil law. Finally, the issue of bankruptcy and the consequences of registration or the decision to impose a ban on disposal on the cadastral sheet is also mentioned.

description: IRC +10420 and AFGL 2343 are the unique, known yellow hypergiants (YHGs) presenting a heavy circumstellar envelope (CSE). We aim to study the morphology, exceptional kinematics, and excitation conditions of their CSEs, and the implications for mass-loss processes. We have mapped the 12CO J=2-1 and 1-0 emission in these YHGs with the IRAM Plateau de Bure interferometer and the 30m telescope. We developed LVG models in order to analyze their circumstellar characteristics. The maps show that the overall shape of both CSEs is approximately spherical, although they also reveal several aspherical features. The CSE around IRC +10420 shows a rounded extended halo surrounding a bright inner region, with both components presenting aspherical characteristics. It presents a brightness minimum at the center. The envelope around AFGL 2343 is a detached shell, showing spherical symmetry and clumpiness at a level of about 15% of the maximum brightness. The envelopes expand isotropically at about 35 km/s, about two or three times faster than typical CSEs around AGB stars. High temperatures (~ 200 K) are derived for the innermost regions in IRC +10420, while denser and cooler (~ 30 K) gas is found in AFGL 2343. The mass-loss processes in these YHGs have been found to be similar. The deduced mass-loss rates (~ 10E-4 - 10E-3 Msun/yr) are much higher than those obtained in AGB stars, and they present significant variations on time scales of ~ 1000 yr.

description: Figure S8. Multiple-hit model for ASD excluding DNM cases. Shown are comparisons of autism probands and unaffected siblings with one or more DNM. Logistic histograms compare residual DNM counts (DNM number residuals, note: after correction, a residual of 0 does not represent a count of 0) adjusted for the father’s age at birth and gender, and the probability of being a proband or unaffected sibling. This analysis demonstrates an increased burden of multiple hits among affected individuals (OR = 1.15, p = 0.0278) (a). When samples are stratified by genetic sex, we observe a slight increase but no significant effect among males (OR = 1.09, p = 0.6) (b), while females demonstrate a stronger (OR = 1.3, p = 0.037) (c) effect than the grouped analysis.

description: We investigate the dynamical fixed points of the zero temperature Glauber dynamics in Ising-like models. The stability analysis of the fixed points in the mean field calculation shows the existence of an exponent that depends on the coordination number $z$ in the Ising model. For the generalised voter model, a phase diagram is obtained based on this study. Numerical results for the Ising model for both the mean field case and short ranged models on lattices with different values of $z$ are also obtained. A related study is the behaviour of the exit probability $E(x_0)$, defined as the probability that a configuration ends up with all spins up starting with $x_0$ fraction of up spins. An interesting result is $E(x_0) = x_0$ in the mean field approximation when $z=2$, which is consistent with the conserved magnetisation in the system. For larger values of $z$, $E(x_0)$ shows the usual finite size dependent non linear behaviour both in the mean field model and in Ising model with nearest neighbour interaction on different two dimensional lattices. For such a behaviour, a data collapse of $E(x_0)$ is obtained using $y = \frac{(x_0 - x_c)}{x_c}L^{1/ν}$ as the scaling variable and $f(y)=\frac{1+\tanh(λy)}{2}$ appears as the scaling function. The universality of the exponent and the scaling factor is investigated.

description: We study Maxwell-Chern-Simons theory in 2 noncommutative spatial dimensions and 1 temporal dimension. We consider a finite matrix model obtained by adding a linear boundary field which takes into account boundary fluctuations. The pure Chern-Simons has been previously shown to be equivalent to the Laughlin description of the quantum Hall effect. With the addition of the Maxwell term, we find that there exists a rich spectrum of excitations including solitons with nontrivial "magnetic flux" and quasi-holes with nontrivial "charges", which we describe in this article. The magnetic flux corresponds to vorticity in the fluid fluctuations while the charges correspond to sources of fluid fluctuations. We find that the quasi-hole solutions exhibit a gap in the spectrum of allowed charge.

description: This study examines a basic assumption of peer review, namely, the idea that there is a consensus on evaluation criteria among peers, which is a necessary condition for the reliability of peer judgements. Empirical evidence indicating that there is no consensus or more than one consensus would offer an explanation for the disagreement effect, the low inter-rater reliability consistently observed in peer review. To investigate this basic assumption, we have surveyed all humanities scholars in Switzerland on 23 grant review criteria. We have employed latent class tree modelling to identify subgroups in which scholars rated criteria similarly (i.e. latent classes) and to explore covariates predicting class membership. We have identified two consensus classes, two consensus-close classes, and a consensus-far class. The consensus classes contain a core consensus (ten criteria related to knowledge gaps, feasibility, rigour, comprehensibility and argumentation, and academic relevance, as well as to the competence and experience of the applicant) and a broad consensus that includes the core consensus plus eight contribution-related criteria, such as originality. These results provide a possible explanation for the disagreement effect. Moreover, the results are consistent with the notion of conservatism, which holds that original research is undervalued in peer review, while other aspects, such as methodology and feasibility, are overweighted. The covariate analysis indicated that age and having tenure increases from the consensus-far to the consensus-close to the consensus classes. This suggests that the more academic experience scholars accumulate, the more their understanding of review criteria conforms to the social norm.

description: This article is concerned in establishing the existence and regularity of solution of semi-hyperbolic patch problem for two-dimensional isentropic Euler equations with van der Waals gas. This type of solution appears in the transonic flow over an airfoil and Guderley reflection and is very common in the numerical solution of Riemann problems. We use the idea of characteristic decomposition and bootstrap method to prove the existence of global smooth solution which is uniformly $C^{1, \frac{1}{2}}$ continuous up to the sonic curve. We also prove that the sonic curve is $C^{1, \frac{1}{2}}$ continuous. Further, we show the formation of shock as an envelope for positive characteristics before reaching their sonic points.
Superconductivity in spin-$3/2$ systems: symmetry classification, odd-frequency pairs, and Bogoliubov Fermi surfaces

description: The possible symmetries of the superconducting pair amplitude is a consequence of the fermionic nature of the Cooper pairs. For spin-$1/2$ systems this leads to the $\mathcal{SPOT}=-1$ classification of superconductivity, where $\mathcal{S}$, $\mathcal{P}$, $\mathcal{O}$, and $\mathcal{T}$ refer to the exchange operators for spin, parity, orbital, and time between the paired electrons. However, this classification no longer holds for higher spin fermions, where each electron also possesses a finite orbital angular momentum strongly coupled with the spin degree of freedom, giving instead a conserved total angular moment. For such systems, we here instead introduce the $\mathcal{JPT}=-1$ classification, where $\mathcal{J}$ is the exchange operator for the $z$-component of the total angular momentum quantum numbers. We then specifically focus on spin-$3/2$ fermion systems and several superconducting cubic half-Heusler compounds that have recently been proposed to be spin-$3/2$ superconductors. By using a generic Hamiltonian suitable for these compounds we calculate the superconducting pair amplitudes and find finite pair amplitudes for all possible symmetries obeying the $\mathcal{JPT}=-1$ classification, including all possible odd-frequency (odd-$ω$) combinations. Moreover, one of the very interesting properties of spin-$3/2$ superconductors is the possibility of them hosting a Bogoliubov Fermi surface (BFS), where the superconducting energy gap is closed across a finite area. We show that a spin-$3/2$ superconductor with a pair potential satisfying an odd-gap time-reversal product and being non-commuting with the normal-state Hamiltonian hosts both a BFS and has finite odd-$ω$ pair amplitudes. We then reduce the full spin-$3/2$ Hamiltonian to an effective two-band model and show that odd-$ω$ pairing is inevitably present in superconductors with a BFS and vice versa.

We demonstrate that the second peak recently observed in the cross section of $η$ photoproduction on the neutron at $\sqrt{s}$=1.66 GeV can be explained in terms of coupled-channel effects due to $S_{11}(1650)$ and $P_{11}(1710)$ resonance excitations.
Influence of conifer release treatments on habitat structure and small mammal populations in south-central British Columbia

description: I examined the effects of manual cutting and cut-stump applications of glyphosate herbicide on vegetation, woody debris, and small mammal populations in young mixed-conifer plantations of south-central British Columbia, Canada. The experimental design consisted of nine separate and independent plantations: 3 controls, 3 manual treatments, and 3 cut-stump treatments. Treatments were conducted between 21 September and 17 October 1992. Vegetation and woody debris were sampled once within each plantation during the last pre treatment year (1992) and again during the first post-treatment year (1993). Small mammal populations were sampled at three-week intervals within each plantation from September 1991 to October 1993 during snow-free periods. Total volumes of space occupied by herbs, coniferous trees, and woody debris were not affected by manual and cut-stump treatments for conifer release. However, both treatments reduced total volumes of shrubs and deciduous trees. The number of pieces of small diameter woody debris increased following the cutting of competing vegetation and increased the complexity of low ground cover on treated plantations. There were no discernable effects of manual or cut-stump treatments on the population size of deer mice (Peromyscus maniculatus), yellow-pine chipmunks (Tamias amoenus), southern redbacked voles (Clethrionomys gapperi), long-tailed voles (Microtus longicaudus), or meadow voles (M. pennsylvanicus). Sex ratios, body weights, reproduction, recruitment, and survival of deer mice were also similar on treatment and control plantations. Changes in habitat structure during the first post-treatment year did not appear to exceed the tolerance of small mammal populations for early successional change. Continued sampling on these plantations will establish whether there are any long-term treatment effects.

description: Edgeworthia tomentosa (Thunb.) Nakai belongs to Thymelaeaceae family, its alabastrum is used as the traditional Chinese medicine ‘Buddleja Officinalis Maxim’. The present study was to elucidate the ultrastructure characteristics of the flower, the phytochemical composition of the aroma essential oils (EOs) and the relevant antimicrobial properties. There were exclusive characters of calyx, ovule, anther and pollen grain of the flowers under scanning electron microscopy. A total of 40 phytochemical components representing 98% of the EOs were successfully identified: monoterpenes and sesquiterpenes were the dominant terpenoids according to Kovats retention index and MS database. EOs exhibited a broad spectrum antimicrobial activity against Gram-positive and Gram-negative bacteria, the best bacteriostatic effect was against Diplococcus pneumonia with MIC and MBC values ranging between 7.8 and 62.5 and 26.0–71.0 μg/mL, respectively. These results demonstrate that the surface microscopic morphological characteristics of Edgeworthia chrysantha Lindl. flowers, are full-scale chemical composition and antimicrobial properties of the EOs.

description: Simple and effective techniques for loading barium ions into linear Paul traps are demonstrated. Two-step photoionization of neutral barium is achieved using a weak intercombination line (6s2 1S0 6s6p 3P1, 791 nm) followed by excitation above the ionization threshold using a nitrogen gas laser (337 nm). Isotopic selectivity is achieved by using a near Doppler-free geometry for excitation of the triplet 6s6p 3P1 state. Additionally, we report a particularly simple and efficient trap loading technique that employs an in-expensive UV epoxy curing lamp to generate photoelectrons.

description: We discuss issues of structural and practical identifiability of partially observed differential equations which are often applied in systems biology. The development of mathematical methods to investigate structural non-identifiability has a long tradition. Computationally efficient methods to detect and cure it have been developed recently. Practical non-identifiability on the other hand has not been investigated at the same conceptually clear level. We argue that practical identifiability is more challenging than structural identifiability when it comes to modelling experimental data. We discuss that the classical approach based on the Fisher information matrix has severe shortcomings. As an alternative, we propose using the profile likelihood, which is a powerful approach to detect and resolve practical non-identifiability.

description: This thesis was carried out as part of the postgraduate program “Environmental Protection and sustainable development” of the Department of Civil Engineering of Aristotle University of Thessaloniki. The aim of this thesis is to highlight the importance of Satellite Data to study disasters. Particular emphasis is placed on fires in general and on fire of 2016 on the island of Thasos in particular. This is easily understood from the structure and the contents of the essay, as they are separate chapters of great importance and gravity. Specifically, in the early chapters of the essay some basic concepts of Remote Sensing are given. These, are necessary to further engage in the essay. In addition, an analysis of catastrophic phenomena is placed, with emphasis on types, causes and factors of the disasters. Furthermore, a reference is made to the modern approach of the management of disasters and fires through statistics of Greece and through case studies about the use of satellite data of fires. It also presents the case study of fire of 2016 to Thassos under Visual observation -interpretation of satellite images, the results of spectral image improvements and normalized difference vegetation index NDVI.

Hot Accretion With Conduction: Spontaneous Thermal Outflows

description: Motivated by the low-collisionality of gas accreted onto black holes in Sgr A* and other nearby galactic nuclei, we study a family of 2D advective accretion solutions with thermal conduction. While we only impose global inflow, the accretion flow spontaneously develops bipolar outflows. The role of conduction is key in providing the extra degree of freedom (latitudinal energy transport) necessary to launch these rotating thermal outflows. The sign of the Bernoulli constant does not discriminate between inflowing and outflowing regions. Our parameter survey covers mass outflow rates from ~ 0 to 13% of the net inflow rate, outflow velocities from ~0 to 11% of the local Keplerian velocity and outflow opening angles from ~ 0 to 60 degs. As the magnitude of conduction is increased, outflows can adopt a conical geometry, pure inflow solutions emerge, and the limit of 2D non-rotating Bondi-like solutions is eventually reached. These results confirm that radiatively-inefficient, hot accretion flows have a hydrodynamical propensity to generate bipolar thermal outflows.

description: We study the inverse Compton scattering of solar photons by Galactic cosmic-ray electrons. We show that the gamma-ray emission from this process is substantial with the maximum flux in the direction of the Sun; the angular distribution of the emission is broad. This previously-neglected foreground should be taken into account in studies of the diffuse Galactic and extragalactic gamma-ray emission. Furthermore, observations by GLAST can be used to monitor the heliosphere and determine the electron spectrum as a function of position from distances as large as Saturn's orbit to close proximity of the Sun, thus enabling unique studies of solar modulation. This paves the way for the determination of other Galactic cosmic-ray species, primarily protons, near the solar surface which will lead to accurate predictions of gamma rays from pp-interactions in the solar atmosphere. These albedo gamma rays will be observable by GLAST, allowing the study of deep atmospheric layers, magnetic field(s), and cosmic-ray cascade development. The latter is necessary to calculate the neutrino flux from pp-interactions at higher energies (>1 TeV). Although this flux is small, it is a "guaranteed flux" in contrast to other astrophysical sources of neutrinos, and may be detectable by km^3 neutrino telescopes of the near future, such as IceCube. Since the solar core is opaque for very high-energy neutrinos, directly studying the mass distribution of the solar core may thus be possible.

description: We construct a family of additive endomorphisms $Ψ_k, k=1, 2...$ of the Grothendieck ring of quasiprojective varieties and the Grothendieck ring of Chow motives similar to the Adams operations in the K-theory. The speciality of the $λ$-structure on the Grothendieck ring of motives (proved by F. Heinloth) gives a set of natural equations for these operations. We discuss this construction in a general setting and relate it to the concept of power structures introduced by S. Gusein-Zade, I. Luengo and A. Melle-Hernandez. Some interpretation of the E. Getzler's formula for the equivariant Hodge-Deligne polynomial of the configuration spaces is also discussed.

description: We extend a recent study that explained the steep falloff in the fusion cross section at energies far below the Coulomb barrier for the symmetric dinuclear system 64Ni+64Ni to another symmetric system, 58Ni+58Ni, and the asymmetric system 64Ni+100Mo. In this scheme the very sensitive dependence of the internal part of the nuclear potential on the nuclear equation of state determines a reduction of the classically allowed region for overlapping configurations and consequently a decrease in the fusion cross sections at bombarding energies far below the barrier. Within the coupled-channels method, including couplings to the low-lying 2+ and 3- states in both target and projectile as well as mutual and two-phonon excitations of these states, we calculate and compare with the experimental fusion cross sections, S-factors, and logarithmic derivatives for the above mentioned systems and find good agreement with the data even at the lowest energies. We predict, in particular, a distinct double peaking in the S-factor for the far subbarrier fusion of 58Ni+58Ni which should be tested experimentally.

description: Η οδική ασφάλεια αποτελεί μείζον κοινωνικό και οικονομικό θέμα, σε εθνικό και σε ευρωπαϊκό επίπεδο. Η Ελλάδα καταλαμβάνει μια από τις χαμηλότερες θέσεις μέσα στην Ευρώπη των 27 κρατών-μελών, όσον αφορά το επίπεδο της ασφάλειας των οδικών δικτύων της. Είναι εμφανές ότι η μελέτη των τροχαίων ατυχημάτων και η βελτίωση της οδικής ασφάλειας και οδικής συμπεριφοράς αποτελεί μονόδρομο. Εξετάζοντας τα τροχαία ατυχήματα γίνεται αντιληπτό ότι τις περισσότερες φορές δεν αποτελούν τυχαία και ανεξάρτητα συμβάντα. Η παρούσα εργασία αφορά την στατιστική ανάλυση και επεξεργασία των τροχαίων ατυχημάτων στην Ανατολική Περιφερειακή Οδό Θεσσαλονίκης, κατά τα έτη 2005 ως και 2016, την ποιοτική αξιολόγηση του επιπέδου οδικής ασφάλειας της Α.Π.Ο.Θ. και την διερεύνηση των γεωμετρικών, λειτουργικών, κυκλοφοριακών και λοιπών χαρακτηριστικών της. Μέσα από την εξέταση των τροχαίων ατυχημάτων και την αποτύπωση τους κατά μήκος της Α.Π.Ο.Θ., επιχειρείται η βελτίωση του επιπέδου οδικής ασφάλειας, μέσω του εντοπισμού των μελανών της σημείων και των αιτιών που προκαλούν τα συγκεκριμένα ατυχήματα. Αναγνωρίζοντας τυχόν κοινά στοιχεία και πραγματοποιώντας μια πολυκριτηριακή προσέγγιση, γίνεται εντοπισμός των προβλημάτων και προτείνονται λύσεις έτσι ώστε να επιλυθούν
description: Road safety is a major social and economic issue, at national and European level. Greece occupies one of the lowest positions in the Europe of the 27 Member States, as regards the level of the road safety. It is evident that the study of the car accidents and the improvement of road safety and road behavior is a one-way street. Looking at car accidents, it is clear that most of the time, they are not accidental and independent events.The present thesis concerns the statistical analysis and processing of traffic accidents on the Eastern Ring Road of Thessaloniki, during the years 2005 to 2016, the qualitative assessment of the level of road safety of the E.R.R.Th.. and exploring its geometrical, functional, traffic and other features. Through the investigation of traffic accidents and their depiction along the E.R.R.Th., attempts are made to improve the level of road safety by identifying the inks of the signs and the causes of these accidents. By recognizing any common elements and making a multi-criteria approach, problems are identified and solutions are proposed to be resolved

классификация биотопов
Ненецкий автономный округ
редкие виды

description: Предложена классификация местообитаний, в основу которой положены топографическое положение биотопов и диагностирующие их территориальные единицы растительности (ТЕР). Последние представляют собой фитоценозы (для многих из которых установлен синтаксономический статус ранга ассоциации и ниже), экологические или серийные ряды и комплексы. При таком подходе любой ландшафт рассматривается как комплекс территориально связанных местообитаний. Для территории заповедника «Ненецкий» выделены 4 категории местообитаний первого уровня, 15 – второго и 38 – третьего. Выделение местообитаний первого и второго уровней преимущественно основано на их топографическом положении, третьего – хорошо диагностируется ТЕР. Наибольшим (28) разнообразием биотопов второго–третьего уровней отличается кластер заповедника «Захарин берег», наименьшим (20) – «Болванский». Из 22 местообитаний кластера «Островной» семь категорий характерны только для группы островов Долгий, Матвеев, Большой и Малый Зеленцы, что объясняется выходом на поверхность карбонатных пород и наличием скалистых и галечных берегов. Именно в этих биотопах сосредоточено наибольшее число видов редких растительных объектов, включенных в Красную книгу Ненецкого автономного округа. Для большинства категорий разработанной классификации установлено их соответствие с категориями European Union Nature Information System (EUNIS), которая является общеевропейской интегрирующей системой местообитаний и, несмотря на недостатки, выступает в качестве стандарта, обеспечивающего сопоставимость национальных и международных классификаций.

description: Electric quadrupole (E2) matrix elements provide a measure of nuclear deformation and related collective structure. Ground-state quadrupole moments in particular are known to high precision in many p-shell nuclei. While the experimental electric quadrupole moment only measures the proton distribution, both proton and neutron quadrupole moments are needed to probe proton-neutron asymmetry in the nuclear deformation. We seek insight into the relation between these moments through the ab initio no-core configuration interaction (NCCI), or no-core shell model (NCSM), approach. Converged ab initio calculations for quadrupole moments are particularly challenging, due to sensitivity to long-range behavior of the wave functions. We therefore study more robustly-converged ratios of quadrupole moments: across mirror nuclides, or of proton and neutron quadrupole moments within the same nuclide. In calculations for mirror pairs in the p shell, we explore how well the predictions for mirror quadrupole moments agree with experiment and how well isospin (mirror) symmetry holds for quadrupole moments across a mirror pair.

В статье представлены списки аборигенных видов четырех флор муниципальных районов. Проведено их сравнение по таксономическому составу. Установлено, что флоры районов сходны, так как имеется 523 общих вида, что свидетельствует о выявлении основного ядра естественной флоры одного из четырех флористических районов Удмуртии. Наиболее богатой по числу аборигенных видов растений является территория Якшур-Бодьинского района, так как она имеет большее разнообразие экотопов в связи с большей расчлененностью рельефа по сравнению с другими сравниваемыми районами. На его территории сохранился ряд неморальных реликтов, таких как Polystichum braunii, Bromopsis benekenii, Galeobdolon luteum , и представителей сибирской и уральской флор – Paeonia anomala, Knautia tatarica.

The effect of season and shrub-grass combination on the fodder quality of three agroforestry plant species grown in Maseno, Western Kenya

description: An experiment to study the effect of season and shrub-grass combinations on the fodder quality of leucaena (Leucaena leucocephala), calliandra (Calliandra calothvrsus) and Napier grass (Pennisetum purpureum) was established at Maseno, western Kenya. The species were managed as hedgerows on field bunds in a randomized complete block design with seven treatments and four replications. Fresh and dry leafy biomass assessments, and sample collection were done at two-month harvesting intervals for 18 months. Percent dry matter was determined by oven-drying approximately 500 g of fresh samples at 60 °C for 48-72 hours. Dried samples were ground to pass a 1 mm sieve and analysed for N (used for crude protein estimation), P, Ca, K, Mg, Zn, Cu and ADF (acid detergent fibre). Statistical analysis was done using SAS 6.04 at ⍺=0.05 significance level. Napier grass was highest in fresh and dry biomass productivity. Biomass productivity, however, dropped significantly in the second year. Biomass productivity of shrubs was lower, but was maintained at similar levels throughout the study period. Leucaena was highest in crude protein, Ca and Cu, but lowest in Zn and ADF. Calliandra was highest in P, Zn and ADF, but was lowest in K and Mg. Napier grass was highest in K and Mg, but was lowest in crude protein, Ca, P and Cu. Except in the leucaena-Napier grass mixture, where differences were not significant, establishment in shrub-grass combinations caused significant increases in the biomass yields of Napier grass. Biomass yields of the woody perennials were either increased significantly or were not affected. Nutrient concentrations of the legume plants were not significantly changed by shrub-grass combinations. The same is true of the Napier grass for most nutrients except K and Mg. The former was increased significantly in combination with both legumes, while the latter was significantly reduced in combination with calliandra, but remained unchanged in combination with leucaena. Except for K content in Napier grass (r=0.750), biomass and nutrients were not significantly correlated with rainfall. Other correlations were not significant and varied with species and parameter. It is suggested that the presence of at least some rainfall in all months maintained a reasonable level of moisture in the soil, so that adverse effects caused by prolonged drought in other areas were not observed at Maseno. Napier grass is suitable for providing the basic ration, while trees and shrubs have a significant potential as high nutrient supplements to conventional animal feeds. These can conveniently be established as tree or shrub-grass combinations. Attempts to diversify the genetic base of fodder trees and shrubs should be made to overcome problems related to toxicity, poor digestibility and the occurrence of pests and diseases.

description: We report the observation of the spin valve effect in (Ga,Mn)As/p-GaAs/(Ga,Mn)As trilayer devices. Magnetoresistance measurements carried out in the current in plane geometry reveal positive magnetoresistance peaks when the two ferromagnetic layers are magnetized orthogonal to each other. Measurements carried out for different post-growth annealing conditions and spacer layer thickness suggest that the positive magnetoresistance peaks originate in a noncollinear spin valve effect due to spin-dependent scattering that is believed to occur primarily at interfaces.
