description: The electronic properties of disordered systems at the Anderson metal-insulator transition (MIT) have been the subject of intense study for several decades. Thermoelectric properties at the MIT, such as thermopower and thermal conductivity, however, have been relatively neglected. Using the recursive Green's function method and the Chester-Thellung-Kubo-Greenwood formalism, we calculate numerically the low temperature behaviour of all kinetic coefficients. From these we can deduce for example the electrical conductivity and the thermopower at finite temperatures. Here we present results for the case of completely coherent transport in cubic 3D systems.

description: Die Felsnische von Uppony I, im Norden des Bükk-Gebirges, Ungarn, lieferte eine reiche Säugetier- und Molluskenfauna. Die Wurzeln der Säugetier-Fauna liegen bis zu einem gewissen Grad im „Biharium". Für die obersten Abschnitte der Sedimentfüllung darf Einstufung in eine Kaltphase vor der Rißeiszeit (i. e. S.) angenommen werden. Die Molluskenfauna, im Gesamtzeitraum sich nicht grundsätzlich verändernd, besteht aus Arten des Waldes und des offenen Geländes, wozu sich oben Elemente des Lösses gesellen. Fledermäuse treten in den tiefsten Schichten, die dem Sediment nach weiter innen im ursprünglichen Höhlenraum abgelagert wurden, in größerer Zahl auf. Die Wühlmaus-Reste, aus Eulengewöllen stammend, häufen sich eher bei Umbildung zur Felsnische infolge Rückwitterung des Traufes. Dabei ist eine, parallel mit der Veränderung der Sedimentation zu beobachtende Anreicherung von Wald bewohnenden Arten bzw. der sibirischen Wühlmaus vorhanden.

description: Roots and Tubers have been until recently a major component of local diets in the Tropics. Their production has been mostly for household consumption and local markets, exporting only a relatively small proportion of produce. In spite of a long term agricultural decline, self-sufficiency in roots and tubers was the norm in Puerto Rico until the early 1980s. From then onwards, production declined significantly as imports experienced more than concomitant increases. This paper by examining global and local production and trade statistics since 1964, local agricultural and marketing developments, and the available technological literature on roots and tubers explores the interface between global processes and local conditions. Preliminary results suggest that changes in the global and local marketing of food crops have been more responsible for the current status of roots and tubers production in Puerto Rico than technological change.

description: The effect of meson retardation in $NN$-interaction and exchange currents on deuteron electrodisintegration is studied in a coupled channel approach including $NN$-, $N Δ$- and $πd$-channels. It is shown that the influence of retardation depends on the energy regime: Whereas below $π$-threshold calculations with static and retarded operators yield almost identical results, they differ significantly in the $Δ$-region. Especially, the longitudinal and the longitudinal-transverse interference structure functions are strongly affected.

description: Auf Grund geomorphologischer Untersuchungen zur Abfolge der Formungsstadien im Bereich der beiden Flußsysteme Oued Termamane — Oued Zigzaou und Oued En Negueb — Oued El Hallouf — Oued Oum Ez Zessar in der nördlichen Djeffara in Südtunesien lassen sich oberhalb des rezenten Flußbetts neben jüngsten, durch menschliche Eingriffe verursachten Ablagerungen eine aus Feinsedimenten aufgebaute „Jüngere Akkumulation", eine überwiegend aus Grobschottern bestehende „Hauptakkumulation" und nicht sicher zu korrelierende Reste von zumindest zwei älteren, höher gelegenen Niveaus unterscheiden. Die „Hauptakkumulation" ist im gesamten Bereich der genannten Oueds, die „Jüngere Akkumulation" dagegen nur in ihren Mittel- und Unterläufen verbreitet. Letztere fehlt im Hauptverbreitungsgebiet der Schluffe von Matmata (primär äolisch abgelagerte und später fluviatil überformte Sedimente) im Gebirge und am Gebirgsrand. Die Ablagerung der „Jüngeren Akkumulation" ist auf Grund der 14C-Datierung von 2 Holzkohlenproben (Hv 5566 und Hv 5400) in einen Zeitraum etwa zwischen 9000 — 7000 Jahre B.P. zu stellen, die Datierung einer Kalkkruste vom Top der „Hauptakkumulation" ergab ein 14C-Alter von 21385 ± 235 Jahre B.P. (Hv 5402). Auch unter Berücksichtigung der erheblichen Fehlermöglichkeiten dieser Datierung ist ein würmzeitliches oder älteres Alter der „Hauptakkumulation" anzunehmen. Die Schluffe von Matmata überlagern die „Hauptakkumulation" und kommen als Materiallieferant für die Sedimente der „Jüngeren Akkumulation" in Frage; daher ist mit einem würmzeitlichen bis frühholozänen Alter der Schluffe zu rechnen. Hinweise auf im Vergleich zu heute feuchtere klimatische Bedingungen geben eine fossile „Kalkbraunerde" in den Schluffen von Matmata, das Vorkommen von Kalkkrusten und ein Schottertransport zur Zeit der „Hauptakkumulation", der erheblich weiter in das Matmatavorland reichte als der Schottertransport der rezenten Flußbetten.

description: Improved seed is a fundamental input in the transfer of crop production technologies to, and their efficient utilisation by farmers. Full exploitation by developing countries of the results from crop research is possible only when there exists, among other things, effective seed supply mechanisms that are responsive to farmers' needs for adequate, timely and affordable supplies of quality seed of improved varieties. In many Caribbean countries these mechanisms are still underdeveloped despite significant investment of resources, both national and in the form of assistance from bilateral and multilateral agencies, over the years. Underdevelopment of the seed sector imposes constraints on crop production and productivity, on the economic exploitation of the food crop genetic resources available in the region, and on the capability of countries to respond to disaster events that affect the food crop sector. Quality seed of improved, adapted varieties is pivotal to the expansion, improvement and sustainability of crop agriculture in the Caribbean and requires that national and regional policies be enacted, and appropriate strategies implemented to ensure, and assure, the adequacy, timeliness, reliability and affordability of improved seed throughout the region.

description: The 1/N expansion of the two-particle irreducible (2PI) effective action is employed to compute universal properties at the second-order phase transition of an O(N)-symmetric N-vector model directly in three dimensions. At next-to-leading order the approach cures the spurious small-N divergence of the standard (1PI) 1/N expansion for a computation of the critical anomalous dimension eta(N), and leads to improved estimates already for moderate values of N.

Abstract-—The current internet architecture is inefficient in fulfilling the demands of newly emerging internet applications. To address this issue, several over-the-top (OTT) application-level solutions have been employed, making the overall architecture very complex. Information-centric-networking (ICN) architecture has emerged as a promising alternative solution. The ICN architecture decouples the content from the host at the network level and supports the temporary storage of content in an innetwork cache. Fundamentally, the ICN can be considered a multisource, multicast content-delivery solution. Because of the benefits of network coding in multicasting scenarios and proven benefits in distributed storage networks, the network coding is apt for the ICN architecture. In this study, we propose a solvable linear network-coding scheme for the ICN architecture. We also propose a practical implementation of the network-coding scheme for the ICN, particularly for the content-centric network (CCN) architecture, which is termed the coded CCN (CCCN). The performance results show that the network-coding scheme improves the performance of the CCN and significantly reduces the network traffic and average download delay.
The impact of cultural orientation on the perceived value of IT mediated customer service in an e-business context
Creators: name: Schmidt, Donald
Publisher: name: University of British Columbia
Year: 2011

description: Electronic commerce (e-commerce) has not only opened up new and lucrative markets globally, it has generated novel business models and a new birthplace for innovation in customer service. Historically customers have been won or lost at times based not on products themselves but rather on the perceived value of ancillary services that are provided before, during, and after the actual product purchase. Because, in the case of E-commerce, these services are provided without direct human intervention, e-commerce websites designers have a unique opportunity to contribute to the success of their organization by providing services (usually information related), that automate the functions for attending to potential customers' needs during the E-commerce purchase process, like providing product information or handling a credit card transaction. Cenfetelli, Benbasat, & AI-Natour (2005) have called these functions 'Information Technology Mediated Customer Services or ITMCS. Because the literature supports the position that providing services has a high social component even when conducted via IT, there is reason to expect culture to influence the users' appreciation of the value of these automated services. The current study found some evidence that Internet users distinguish differences in the cultural relevance of the various kinds of website service offerings in a predictable and measurable way. The Internet users reported preferences for functions or features in a pattern that related to their cultural orientation. The conclusion from this research is that further research might capture the kinds of findings that website designers could use to make 'either/or' decisions about which customer service functions to provide in their website to best appeal to the key cultural traits of their target market audiences.

description: In der Löss-/Paläobodenabfolge des Profils Schatthausen aus dem nördlichen Baden-Württemberg ist den Lössen ein Bt-Horizont oberhalb eines letztinterglazialen Paläobodens zwischengeschaltet. Diese Befunde fordern eine genauere Untersuchung von polygenetisch überprägten Paläoböden, um eine mögliche chronostratigraphische Fehlinterpretation zu vermeiden. Der Humushorizont und der darunter liegende Bt-Horizont entstanden während zweier Bodenbildungsphasen. Diese Annahme wird durch paläopedologische Befunde, Phytolite und Lumineszenz-Datierungen unterstützt. Der untere Bt-Horizont (Bt1) wurde vermutlich während des Eem gebildet. Die Sedimente des obersten Bt-Horizontes (Bt2) wurden um 71.5±7.4 ka abgelagert und durch eine Bodenbildung, vermutlich während des Mittelwürm, überprägt. Die Sedimente des Ah-Horizontes des Bt2-Horizontes ergaben Infrarot Optisch Stimulierte Lumineszenz (IRSL)-Datierungen zwischen 52.5±5.5 ka und 45.4±4.7 ka und bestätigen eine Bodenbildung während des Mittelwürm. Perioden unterschiedlicher Staubakkumulation können durch IRSL-Datierungen im Profil quantitativ unterschieden werden: der spätglaziale Löss mit einem gewichteten Alter von 15.2±0.6 ka (n=7), die mittelwürmzeitlichen Sedimente und einem gewichteten Alter von 48.9±2.5 ka (n=4) und die frühwürmzeitlichen Sedimente mit einem Ablagerungsalter von 71.5±7.4 ka sowie nicht physikalisch datierte ältere Lösse. Die IRSL-Alter sind in guter Übereinstimmung mit den geologisch erwarteten Ergebnissen und korrelieren sehr gut mit den letztinterglazialen Perioden maximaler Staubakkumulationsraten aus Grönland (GRIP-Eisbohrkern). Die Lössabfolge von Schatthausen ergänzt die gut gegliederte letztinterglaziale/letztglaziale Löss-Sequenz des benachbarten Nußloch-Profils um den spätglazialen Löss und seine zwischengeschalteten Nassböden.

description: An on-farm trial was conducted to determine optimum plant spacing for West Indian hot pepper (Capsicum chinense L) cultivars. 'Habanero," West Indian Red' and two 'Scotch Bonnet' hot pepper cultivars were planted at three in-row spacings of 41, 46 and 61 cm. All treatment plots consisted of three rows with constant row spacing of 0.91m. The experimental design was three randomized complete blocks of split- plots. The in-row spacings were the main plots and the cultivars were the subplots. Data collected included plant height at first harvest, number and fresh weight of fruits, number of harvests and production period. Yield was estimated by computation of the numbers of plants per hectare factored by the average yield weight per plant. Optimum planting density for 'Jamaica (Red) Scotch Bonnet' and 'Yellow Scotch Bonnet' was at the widest in-row spacing of 61 cm. The 'Scotch Bonnets' also showed a trend of taller plants producing more of fruits as in-row plant spacing was increased. Differences in yield response of cultivars to in-row spacing was significant (P< 0.05), however, yields from 'Habanero' and 'West Indies Red' were less affected. Analysis revealed that yield was mostly influenced by cultivar. In-row spacing x cultivar interaction was not as significant. This study indicates that in-row spacing for attaining the best yield is highly variable for hot pepper cultivars.
Hyporheic exchange processes in a coastal headwater stream
Creators: name: Scordo, Elisa Branson
Publisher: name: University of British Columbia
Year: 2011

description: Hyporheic exchange flow involves the two-way movement of water between the stream channel and the bed and banks. These exchange flows create distinctive habitats and influence biogeochemical processes and water temperatures. This study focused on the characterization of the spatial distribution of subsurface flow pathways and associated travel times through the hyporheic zone within a low-order, high-gradient headwater stream located in the UBC Malcolm Knapp Research Forest, approximately 60 km east of Vancouver, British Columbia. Hyporheic zone processes were examined May to October 2006, at three spatial scales in East Creek: point, channel-unit and reach. Hydrometric data collected from piezometers installed within the stream channel, along with solute injection tracer experiments, were used to characterize subsurface flow pathways within a 100 m stream section. Stream tracer breakthrough curves were used to model the processes of advection, dispersion, lateral inflow and transient storage within the hyporheic zone using the numerical model OTIS-P. Tracer injections at individual step-pool units were used to identify locations of hyporheic discharge, as well as to estimate separate travel times for hyporheic and surface-water transient storage zones. Solute transport process varied with discharge at the reach scale. Transient storage area (As) increased with discharge, while transient exchange coefficient (α) remained fairly constant. At the scale of individual pools, transient storage area and residence times were higher than the reach scale estimate, suggesting that pools and back eddies do contribute to transient storage in headwater streams. Water fluxes calculated with Darcy's Law in one channel-unit did not "scale-up" to the reach scale estimate of hyporheic exchange (α), and was two orders smaller than the reach scale. Direct measurements of water fluxes into the streambed, including vertical hydraulic gradients and infiltration rates, did not vary systematically with discharge. Hydraulic gradients varied significantly with scaled location within the channel-unit, but not with the downstream step height. Hydraulic conductivity varied with site conditions (upwelling, downwelling and neutral sites), suggesting that channel geometry and hydraulic conductivity control exchange flow. This multiple scale approach highlights the considerable spatial and temporal variability and complexity of hyporheic exchange processes within step-pool streams.

description: The spectral order on $\bR$ induces a partial ordering on the manifold $\calH_{n}$ of monic hyperbolic polynomials of degree $n$. We show that the semigroup $\tilde{\calS}$ generated by differential operators of the form $(1-\la \frac{d}{dx})e^{\la \frac{d}{dx}}$, $\la \in \bR$, acts on the poset $\calH_{n}$ in an order-preserving fashion. We also show that polynomials in $\calH_{n}$ are global minima of their respective $\tilde{\calS}$-orbits and we conjecture that a similar result holds even for complex polynomials. Finally, we show that only those pencils of polynomials in $\calH_{n}$ which are of logarithmic derivative type satisfy a certain local minimum property for the spectral order.

description: Preliminary experimentation has indicated that soilless culture media made of local materials in Suriname are cost effective in lettuce production when using a non-circulating hydroponic system. Furthermore, the use of rice hulls as a soilless media with mineral solutions of either Miracle Growth (18-18-21) or Pokon (6-3-6) as nutrient solution has enhanced lettuce production under greenhouse conditions. In this study three lettuce varieties were evaluated on rice hulls utilizing either Miracle Grow or Pokon as a mineral solution in a non-circulating hydroponic system. Results revealed that the average plant weight of Trinity Star was significant higher (p< 0.05) in comparison to the average plant weight of Black Seeded Simpson and Great Lakes 366. Data also showed that the average plant weight of all three lettuce varieties was significantly higher (p< 0.05) when Miracle Grow was used. The pH of the Miracle Grow solution was significantly higher than the pH of Pokon while the EC of Miracle Grow was slightly higher than the EC of the Pokon solution.

description: 4FGL J0935.3+0901 is a gamma-ray source detected by the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope. We have conducted detailed analysis of the LAT data for this source and multi-wavelength studies of the source field. Its gamma-ray emission can be described with a power law ($Γ=2.0\pm0.2$) with an exponential cutoff ($E_c=2.9\pm1.6$ GeV), while the flux shows significant long-term variations. From analysis of archival Neil Gehrels Swift X-ray Telescope data, we find only one X-ray source in the LAT's 2$σ$ error region. Within a 3.7" radius error circle of the X-ray source, there is only one optical object down to $r'\sim$23 mag. Time-resolved photometry of the optical object indicates a likely 2.5~hr periodic modulation, while its spectrum shows double-peaked hydrogen and helium emission lines (similar to those seen in accretion discs in low-mass X-ray binaries). Combining these results, we conclude that we have discovered a compact X-ray emitting binary in likely association with 4FGL J0935.3+0901, i.e., a millisecond pulsar (MSP) binary. We discuss the implication of the optical spectral features: this binary could be a transitional MSP system at a sub-luminous disc state, although the other possibility, the binary in a rotation-powered state showing the optical emission lines due to intrabinary interaction processes, can not be excluded. Further observational studies will help determine detailed properties of this candidate MSP binary and thus clarify its current state.

description: We prove Feigin-Frenkel type dualities between subregular W-algebras of type A, B and principal W-superalgebras of type $\mathfrak{sl}(1|n), \mathfrak{osp}(2|2n)$. The type A case proves a conjecture of Feigin and Semikhatov. Let $(\mathfrak{g}_1,\mathfrak{g}_2) = (\mathfrak{sl}_{n+1},\mathfrak{sl}(1|n+1))$ or $(\mathfrak{so}_{2n+1}, \mathfrak{osp}(2|2n))$ and let $r$ be the lacity of $\mathfrak{g}_1$. Let k be a complex number and $\ell$ defined by $r(k+h^\vee_1)(\ell+h^\vee_2)=1$ with $h^\vee_i$ the dual Coxeter numbers of the $\mathfrak g_i$. Our first main result is that the Heisenberg cosets $\mathcal C^k(\mathfrak g_1)$ and $\mathcal C^\ell(\mathfrak g_2)$ of these W-algebras at these dual levels are isomorphic, i.e. $\mathcal C^k(\mathfrak g_1) \simeq \mathcal C^\ell(\mathfrak g_2)$ for generic k. We determine the generic levels and furthermore establish analogous results for the cosets of the simple quotients of the W-algebras. Our second result is a novel Kazama-Suzuki type coset construction: We show that a diagonal Heisenberg coset of the subregular W-algebra at level $k$ times the lattice vertex superalgebra $V_{\mathbb Z}$ is the principal W-superalgebra at the dual level $\ell$. Conversely a diagonal Heisenberg coset of the principal W-superalgebra at level $\ell$ times the lattice vertex superalgebra $V_{\sqrt{-1}\mathbb Z}$ is the subregular W-algebra at the dual level k. Again this is proven for the universal W-algebras as well as for the simple quotients. We show that a consequence of the Kazama-Suzuki type construction is that the simple principal W-superalgebra and its Heisenberg coset at level $\ell$ are rational and/or C_2-cofinite if the same is true for the simple subregular W-algebra at dual level $\ell$. This gives many new C_2-cofiniteness and rationality results.

Abstract-Authentication is one of the essential security services in Wireless Sensor Networks (WSNs) for ensuring secure data sessions. Sensor node authentication ensures the confidentiality and validity of data collected by the sensor node, whereas user authentication guarantees that only legitimate users can access the sensor data. In a mobile WSN, sensor and user nodes move across the network and exchange data with multiple nodes, thus experiencing the authentication process multiple times. The integration of WSNs with Internet of Things (IoT) brings forth a new kind of WSN architecture along with stricter security requirements; for instance, a sensor node or a user node may need to establish multiple concurrent secure data sessions. With concurrent data sessions, the frequency of the re-authentication process increases in proportion to the number of concurrent connections. Moreover, to establish multiple data sessions, it is essential that a protocol participant have the capability of running multiple instances of the protocol run, which makes the security issue even more challenging. The currently available authentication protocols were designed for the autonomous WSN and do not account for the above requirements. Hence, ensuring a lightweight and efficient authentication protocol has become more crucial. In this paper, we present a novel, lightweight and efficient key exchange and authentication protocol suite called the Secure Mobile Sensor Network (SMSN) Authentication Protocol. In the SMSN a mobile node goes through an initial authentication procedure and receives a re-authentication ticket from the base station. Later a mobile node can use this re-authentication ticket when establishing multiple data exchange sessions and/or when moving across the network. This scheme reduces the communication and computational complexity of the authentication process. We proved the strength of our protocol with rigorous security analysis (including formal analysis using the BAN-logic) and simulated the SMSN and previously proposed schemes in an automated protocol verifier tool. Finally, we compared the computational complexity and communication cost against well-known authentication protocols.

Cubic magnets with Dzyaloshinskii-Moriya interaction at low T

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Ground state and spin-wave spectrum of cubic magnets with the Dzyaloshinskii-Moriya interaction (DMI) such as MnSi and FeGe are studied theoretically. The linear spin-wave theory is developed. The spin-wave spectrum depends strongly on the magnetic field and strongly anisotropic. It is a result of incommensurate magnetic structure when the DMI breaks the total spin conservation law. The spin-wave spectrum is unstable at infinitesimal perpendicular field. If the gap $Δ$ is introduced the spectrum becomes stable. The gap appears due to cubic anisotropy and the spin-wave interaction considered in the Hartree-Fock approximation. Peculiar properties of the ESR and neutron scattering in the helical magnets are considered and possibilities of corresponding experimental studies are discussed.

Model-independent methods to measure the $P$-parity of the $Θ^+$-pentaquark in photoproduction experiments

description: We discuss model independent methods to measure the $P$-parity of the $Θ^+$-pentaquark, in the simplest processes of photoproduction, $γ+N\to \bar{K}+Θ^+$, using definite relations between T-even polarization observables, which depend on the $P$-parity of the $Θ^+$ baryon (with respect to the $NK$ system). One method, which holds for any photon energy and any $K$ meson production angle, is based on the relation between the $Σ_B$ asymmetry (induced by a linearly polarized photon beam, with unpolarized target) and the $D_{nn}$ component of the depolarization tensor (for unpolarized photon beam). Another method, which applies in collinear kinematics (or in threshold conditions), is related to the sign of the $D_{nn}$ component, with linearly polarized photon beam.

description: The aim of the study was to present the diversity consumption of fruit, their preserves and fruit and vegetable juices in the different types of polish households distinguished on the grounds of the socio-economic group and income level, as well as to identify changes in the consumption of fruit in separate types of families in 2007-2014. The highest consumption of fresh fruit appeared in households of retirees and pensioner and in the families with the highest income. The highest consumption of fruit preserves and juices was observed among employees in non-manual labour positions und self-employed. In the all types of households decreased the consumption of apples and berries, while the consumption of exotic fruit increased. In the most type of families increased the consumption of fruit preserves and decreased the consumption of juices.

description: Radial-velocity follow-up of stars harbouring transiting planets detected by TESS is expected to require very large amounts of expensive telescope time in the next few years. Therefore, scheduling strategies should be implemented to maximize the amount of information gathered about the target planetary systems. We consider myopic and non-myopic versions of a novel uniform-in-phase scheduler, as well as a random scheduler, and compare these scheduling strategies with respect to the bias, accuracy and precision achieved in recovering the mass and orbital parameters of transiting and non-transiting planets. This comparison is carried out based on realistic simulations of radial-velocity follow-up with ESPRESSO of a sample of 50 TESS target stars, with simulated planetary systems containing at least one transiting planet with a radius below $4R_{\oplus}$. Radial-velocity datasets were generated under reasonable assumptions about their noise component, including that resulting from stellar activity, and analysed using a fully Bayesian methodology. We find the random scheduler leads to a more biased, less accurate, and less precise, estimation of the mass of the transiting exoplanets. No significant differences are found between the results of the myopic and non-myopic implementations of the uniform-in-phase scheduler. With only about 22 radial velocity measurements per dataset, our novel uniform-in-phase scheduler enables an unbiased (at the level of 1\%) measurement of the masses of the transiting planets, while keeping the average relative accuracy and precision around 16\% and 23\% respectively. The number of non-transiting planets detected is similar for all the scheduling strategies considered, as well as the bias, accuracy and precision with which their masses and orbital parameters are recovered.

description: Ein aus Kiesen und Sauden der Leine-Niederterrasse gebaggerter Schädel eines Steppeniltis (Mustela [Putorius] eversmanni soergeli Éhik) wird zum Anlaß genommen, die stratigraphische und ökologische Aussagekraft dieser Iltis-Art zu überprüfen. M. eversmanni ist in Mitteleuropa bislang mit Sicherheit nur aus verschiedenen Zeitabschnitten des Würm bekannt geworden, nie aus älteren oder jüngeren Schichten. In der Gegenwart ist der Lebensraum des Steppeniltis ziemlich streng an die Halb- bzw. Kultursteppe und an die Vollsteppe gebunden, wobei die wärmeren Teile des eurasiatischen Steppengürtels bevorzugt werden. Auch während des Würm kann die Art nicht unter wesentlich anderen Umweltsverhältnissen gelebt haben. Es wird daraus gefolgert, daß es auch in den Stadialen nicht nur trockenkalte, sondern auch trockenwärmere Phasen gegeben hat.

description: The aim of the research was to establish whether the production of dairy cooperatives, measured by sales value, is connected with the product innovations and environmental protection costs. he data related to years 2004 to 2014. It was found that these factors are usually significant. It was further established that those cost are disproportionately high in relation to the dynamics of production and prices of dairy products. It turned out that environmental protection requirements are so restrictive and cost-effective that they can cause skipping dairy cooperative to the increasing financial, technological and law difficulties. Apart from that the increase of product innovations drops significantly suggesting that the supply is near to saturation in terms of assortments on the market.

description: We introduce a notion of split extension of (non-associative) bialgebras which generalizes the notion of split extension of magmas introduced by M. Gran, G. Janelidze and M. Sobral. We show that this definition is equivalent to the notion of action of (non-associative) bialgebras. We particularize this equivalence to (non-associative) Hopf algebras by defining split extensions of (non-associative) Hopf algebras and proving that they are equivalent to actions of (non-associative) Hopf algebras. Moreover, we prove the validity of the Split Short Five Lemma for these kinds of split extensions, and we examine some examples.
