description: International air travel has long been considered a significant means of moving pest organisms. Passengers may carry pests (e.g., snails, weed seeds), or items that are infested with pests (e.g., fruits or vegetables). Our objective was to use data collected by the U.S. federal government to estimate plant quarantine material (QM) approach rates (the percentage of sampling units containing QMs) and the annual number of plant QMs entering the United States in airline passenger baggage. We concluded that the pest risk associated with passenger baggage may be considerable. In the United States, the risk from international airline passenger baggage can be mainly attributed to travelers who are visiting family or friends (about one third of the travelers). Several Caribbean countries were among the 25 countries of passenger origin with the highest plant QM approach rates.

 Petrolisthes gertrudae Werding, 1996: 300, figs 1, 2 (type locality: Guadeloupe, also Bonaire). — Werding et al. 2003: 81, tab. 1 (Lesser Antilles).
MATERIAL EXAMINED. — None.
DIAGNOSIS. — (Adapted from Werding 1996). Carapace smooth; supra-ocular and external orbital angles unarmed; epibranchial region unarmed.Carpus of cheliped anteriorly rounded, sometimes slightly denticulated on proximal portion; dorsal surface granulated; posterior margin unarmed. Palm of cheliped granulated on dorsal surface; anterior and posterior margins unarmed; anterior margin with thick tuft of long setae, not extended onto fixed finger; gape of fingers without pubescence. Ambulatory legs unarmed and devoid of setae on anterior margins; dactylus with four movable spines on posterior margin. Telson composed of seven plates

title: The effects of environmental complexity upon the aggressive behavior and growth of juvenile brown trout (salmo trutta L.) and the carrying capacity of the environment
Creators: name: North, Eric
Publisher: name: The Open University
Year: 1977

description: Experiments were performed in stream tanks and aquaris to investigate the effects of environmental complexity upon the aggressive behaviour and growth of juvenile brown trout (Salmo trutta L.) and the carrying capacity of the environment. Natural materials and various structures were used to provide environmental complexity. Aggressive interactions were found to be significantly more frequent in simple environments than in complex ones. The different types of structures used to modify the complexity of the experimental environments had different effects upon the observed levels of aggressive behavioral structures providing overhead cover were associated with the lowest levels of aggression. Increasing fish density resulted in relatively greater increase in aggression in simple environment. The wigwag display of the fish was analysed and found to be a highly ritualised, defensive manoeuvre, the efficiency of which was determined by the social ranks of the fish involved. Carrying capacity of complex environments was significantly greater then that of simple environments. There was a significant inverse correlation between aggression and resident population size in the environment types used. In the growth experiment, different relationships between individual fish's specific growth rates and their size rank position were found in populations of fish kept in simple and complex environments. The differences were probably associated with the different levels of aggression observed in the two environment types and the effect of environmental complexity upon feeding behaviour.

description: The Apuseni Mountains were formed during Late Cretaceous convergence between the Tisia and the Dacia microplates as part of the Alpine orogen. The mountain range comprises a sedimentary succession similar to the Gosau Group of the Eastern Alps. This work focuses on the sedimentological and geodynamic evolution of the Gosau basin of the Apuseni Mts. and attempts a direct comparison to the relatively well studied Gosau Group deposits of the Eastern Alps. By analyzing the Upper Cretaceous Gosau sediments and the surrounding geological units, we were able to add critical evidence for reconstructing the Late Mesozoic to Paleogene geodynamic evolution of the Apuseni Mountains. Nannoplankton investigations show that Gosau sedimentation started diachronously after Late Turonian times. The burial history indicates low subsidence rates during deposition of the terrestrial and shallow marine Lower Gosau Subgroup and increased subsidence rates during the period of deep marine Upper Gosau Subgroup sedimentation. The Gosau Group of the Apuseni Mountains was deposited in a forearc basin supplied with sedimentary material from an obducted forearc region and the crystalline hinterland, as reflected by heavy mineral and paleocurrent analysis. Zircon fission track age populations show no fluctuation of exhumation rates in the surrounding geological units, which served as source areas for the detrital material, whereas increased exhumation at the K/Pg boundary can be proven by thermal modeling on apatite fission track data. Synchronously to the Gosau sedimentation, deep marine turbidites were deposited in the deep-sea trench basin formed by the subduction of the Transylvanian Ocean. The similarities to the Gosau occurrences of the Eastern Alps lead to direct correlation with the Alpine paleogeographic evolution and to the assumption that a continuous ocean basin (South Penninic - Transylvanian Ocean Basin) was consumed until Late Cretaceous times.

description: In Puerto Rico, tropical grasses do not adequately meet the nutritional requirements of dairy cows. For this reason, imports alfalfa hay and costly concentrate based diets are used in the dairy industry. It has been widely documented that legumes are generally higher in nutritive value than grasses, but information on forage intake and nutritive value of the annual legumes forage soybean Hinson Long-Juvenile (HLJ) (Gyicine max) and lablab cv. Rongai [Lablab purpureus (L.) Sweet] is limited. The research objective was to compare daily intake, and dry matter, crude protein (CP), and neutral detergent fiber (NDF) digestibility of 'HLJ' and 'Rongai' hay when fed to mature lambs. The experiment was conducted at the University of Puerto Rico, Finca Alzamora using rams (28.4±4 kg BW) in a completely randomized design with three replicates. Rams were housed in individual cages and fed treatment diets for a 7d adaptation period and 5d of data collection. Higher voluntary feed intake (P<0.05) was observed by rams fed 'HLJ' than Rongai (0.944 vs. 0.852 kg/d). Crude protein and NDF concentration were 15.7 and 15.5% and 42.8, and 41.7% for HLJ and Rongai, respectively. CP and NDF digestibility of HLJ and Rongai did not differ (P>0.05). But DM Digestibility (56.2 vs. 49.6%) was higher (P<0.05) in HLJ than Rongai. Both HLJ and Rongai exhibit potential for use in hay conservation systems to improve the feeding value of diet basal on grass hay and minimize concentrate use in dairy cows.

description: Fuzzy spheres appear as classical solutions in a matrix model obtained via dimensional reduction of 3-dimensional Yang-Mills theory with the Chern-Simons term. Well-defined perturbative expansion around these solutions can be formulated even for finite matrix size, and in the case of $k$ coincident fuzzy spheres it gives rise to a regularized U($k$) gauge theory on a noncommutative geometry. Here we study the matrix model nonperturbatively by Monte Carlo simulation. The system undergoes a first order phase transition as we change the coefficient ($α$) of the Chern-Simons term. In the small $α$ phase, the large $N$ properties of the system are qualitatively the same as in the pure Yang-Mills model ($α=0$), whereas in the large $α$ phase a single fuzzy sphere emerges dynamically. Various `multi fuzzy spheres' are observed as meta-stable states, and we argue in particular that the $k$ coincident fuzzy spheres cannot be realized as the true vacuum in this model even in the large $N$ limit. We also perform one-loop calculations of various observables for arbitrary $k$ including $k=1$. Comparison with our Monte Carlo data suggests that higher order corrections are suppressed in the large $N$ limit.

description: One of the properties that makes marble such an excellent construction and ornamental material is its low porosity. It is very difficult for water or decay agents to penetrate the internal structure of materials with no or few pores, so enhancing the durability of these materials. However, environmental temperature fluctuations bring about significant physical changes in marbles that result in an increase in porosity, due to the appearance of new microcracks and the expansion of existing ones. These cracks offer new paths into the marble which make it easier for solutions containing pollutants to penetrate the material. Thermal expansion tests were performed on three different types of marble known as White, Tranco, and Yellow Macael (Almeria, Spain), after which an increase in porosity (from 17 to 73% depending on marble type) was observed, mainly due to crack formation. The structural changes occurring during thermal expansion tests were more significant in the case of White Macael samples, a fact that is not only related to its mineralogical composition but also to the morphology of the grains, grain boundaries and crystal size. Our research suggests that thermally weathered White Macael marble could be more susceptible to decay by other contaminant agents than Tranco or Yellow Macael. The use of hot-stage environmental scanning electron microscopy is proposed as a valid tool for observing, both in situ and at high magnification, changes in the fracture system of building stones induced by thermal stress.

description: There have been many occurrences in Trinidad of lambs and kids that have died within 6 months of birth of suspected Cu deficiency resulting in clinical signs resembling swayback. Animals displayed an inability to stand at birth or hind limb ataxia progressing to an inability to stand in the delayed forms. The condition continues to be of economic importance because of poor growth rates and high mortality of lambs and kids of affected farms.

description: Consider random Young diagrams with a fixed number n of boxes, where the probability distribution on diagrams is determined by the Plancherel measure. That is, the weight of a diagram is proportional to the squared dimension of the corresponding irreducible representation of the symmetric group S_n. As n goes to infinity, the boundary of the (suitably scaled) random diagram concentrates near a curve Omega (Logan-Shepp 1977, Vershik-Kerov 1977). In 1993, Kerov announced a central limit theorem describing Gaussian fluctuations of random diagrams around the limit shape Omega. Here we propose a reconstruction of his proof, largely based on Kerov's unpublished work notes (1999). We also discuss a striking similarity between Kerov's result and central limit theorems for random matrices (Diaconis-Shahshahani, Johansson).

description: We prove the circular law for a class of non-Hermitian random block band matrices with genuinely sublinear bandwidth. Namely, we show there exists $τ\in (0,1)$ so that if the bandwidth of the matrix $X$ is at least $n^{1-τ}$ and the nonzero entries are iid random variables with mean zero and slightly more than four finite moments, then the limiting empirical eigenvalue distribution of $X$, when properly normalized, converges in probability to the uniform distribution on the unit disk in the complex plane. The key technical result is a least singular value bound for shifted random band block matrices with genuinely sublinear bandwidth, which improves on a result of Cook in the band matrix setting.

 Morphological characters
 This soft-furred rat of the so-called P. tullbergi (Thomas, 1894) complex was described from Lake Oku at about 5 km from our new records. Here it represents the most abundant rodent (34% of our captures). The 97 newly collected individuals morphologically fit well with the ZFMK paratypes. Their molecular and morphological distinctiveness towards other Praomys species of the tullbergi complex were recently confirmed (Missoup et al. 2012).

description: Experiments were conducted in Mayagüez, Puerto Rico, to determine the effect of two biostimulants on the in-nursery growth of grapefruit budded on 'Cleopatra' rootstock. A kelp (Ascophyllum nodosum) extract (Stimplex®) and a commercial mixture of amino acids (Macro-Sorb Radicular®) were drenched at several rates, starting one month after budding and repeating the applications every 10 days until the plants reached the adequate transplanting stage. Biostimulant-treated plants attained the adequate transplanting stage earlier than untreated plants. 'Duncan' and 'Marsh' responded equally to the biostimulants, and the extent of growth response was greater as the biostimulant rates increased. These results indicate that both biostimulants may be useful to accelerate the production of 'Duncan' and 'Marsh' grapefruits budded on 'Cleopatra' rootstock.

description: Zerovalent iron (ZVI) has been proposed as reactive material in permeable in situ walls for contaminated groundwater. An economically feasible ZVI-based reactive wall requires cheap but efficient iron materials. From an uranium treatability study and results of iron dissolution in 0.002 M EDTA by five selected ZVI materials, it is shown that current research and field implementation is not based on a rational selection of application-specific iron metal sources. An experimental procedure is proposed which could enable a better material characterization. This procedure consists of mixing ZVI materials and reactive additives, including contaminant releasing materials (CRMs), in long-term batch experiments and characterizing the contaminant concentration over the time.

description: Objectives: (a) to estimate the accuracy of International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code for amyotrophic lateral sclerosis (ALS) in the Hospital Discharge Database (HDD) of the Italian region Friuli-Venezia Giulia; (b) to identify the predictors of a true positive ALS code; (c) to compare incident and prevalent cases obtained from HDD with those identified in a retrospective population-based study. Methods: Records of all patients discharged 2010–2014 with an ICD-9-CM code for ALS and other motor neuron diseases were extracted from the HDD. For each record, all the available clinical documentation was evaluated to confirm or reject the diagnosis of ALS. ALS incident and prevalent cases were identified. Validity measures were calculated both overall and stratified by patient and hospitalization characteristics. Adjusted odds ratio (aOR), with 95% confidence interval (95%CI), of a true positive code was estimated using unconditional logistic regression. Results: ALS code had sensitivity 92.9%, specificity 75.3%, positive predictive value (PPV) 92.3%, and negative predictive value (NPV) 76.8%. A true positive ALS code was predicted by concurrent codes for respiratory interventions (aOR: 3.82; 95%CI: 2.09–6.99), primary position code (2.78; 1.68–4.62), non-programed hospitalization (2.06; 1.18–3.61), male patient (1.56; 1.06–2.29), and hospitalization length <14 days (1.42; 1.07–2.84). Two hundred and thirty-six prevalent and 187 incident cases were identified, 84% of those detected in the population-based study. Conclusion: ALS code shows very good accuracy and identifies a high percentage of true positive, incident and prevalent cases, but additional sources and an algorithm based on selected variables may further improve case identification.
Do fragmentation and accretion affect the stellar Initial Mass Function?

description: While the stellar Initial Mass Function (IMF) appears to be close to universal within the Milky Way galaxy, it is strongly suspected to be different in the primordial Universe, where molecular hydrogen cooling is less efficient and the gas temperature can be higher by a factor of 30. In between these extreme cases, the gas temperature varies depending on the environment, metallicity and radiation background. In this paper we explore if changes of the gas temperature affect the IMF of the stars considering fragmentation and accretion. The fragmentation behavior depends mostly on the Jeans mass at the turning point in the equation of state where a transition occurs from an approximately isothermal to an adiabatic regime due to dust opacities. The Jeans mass at this transition in the equation of state is always very similar, independent of the initial temperature, and therefore the initial mass of the fragments is very similar. Accretion on the other hand is strongly temperature dependent. We argue that the latter becomes the dominant process for star formation efficiencies above 5 - 7 %, increasing the average mass of the stars.

"It's a do-it-yourself hospital" : the experiences of older persons who have been hospitalized without family involvement
Creators: name: Baker, Nancy Ramona
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this qualitative study was to gain an understanding of the experiences of older persons who have been hospitalized without family involvement. A total of five men and women participated in in-depth interviews about their experiences. The principles of hermeneutic phenomenology and narrative analysis were used to tease out the major themes of the participants' experiences . A structural social work lens shed light on how the participants' hospital experiences were shaped by broader structural issues. Both formal and informal support were important factors for these older persons who did not have family support. The roles of hospital social workers, and volunteers were explored. Older persons who have had personal losses including physical decline, and loss of support systems, may feel powerless in a hospital setting. Empowermentoriented social work practice can be used with seniors to help them link personal problems to socio-political issues. Implications for social work practice and policy are discussed. The limitations of this study and avenues for future research are presented.

description: The Mantiqueira Province represents a series of supracrustal segments of the South-American counterpart formed during the Gondwana Supercontinent agglutination. In this crustal domain, the process of escape tectonics played a conspicuous role, generating important NE–N–S-trending lineaments. The oblique component of the motions of the colliding tectonic blocks defined the transpressional character of the main suture zones: Lancinha-Itariri, Cubatão-Arcádia-Areal, Serrinha-Rio Palmital in the Ribeira Belt and Sierra Ballena-Major Gercino in the Dom Feliciano Belt. The process as a whole lasted for ca. 60 Ma, since the initial collision phase until the lateral escape phase predominantly marked by dextral and subordinate sinistral transpressional shear zones. In the Dom Feliciano Belt, southern Brazil and Uruguay, transpressional event at 630–600 Ma is recognized and in the Ribeira Belt, despite less coevally, the transpressional event occurred between 590 and 560 Ma in its northern-central portion and between ca. 625 and 595 Ma in its central-southern portion. The kinematics of several shear zones with simultaneous movement in opposite directions at their terminations is explained by the sinuosity of these lineaments in relation to a predominantly continuous westward compression.

description: Finding the optimal attainable precisions in quantum multiparameter metrology is a non trivial problem. One approach to tackling this problem involves the computation of bounds which impose limits on how accurately we can estimate certain physical quantities. One such bound is the Holevo Cramer Rao bound on the trace of the mean squared error matrix. The Holevo bound is an asymptotically achievable bound when one allows for any measurement strategy, including collective measurements on many copies of the probe. In this work we introduce a tighter bound for estimating multiple parameters simultaneously when performing separable measurements on finite copies of the probe. This makes it more relevant in terms of experimental accessibility. We show that this bound can be efficiently computed by casting it as a semidefinite program. We illustrate our bound with several examples of collective measurements on finite copies of the probe. These results have implications for the necessary requirements to saturate the Holevo bound.

Using the formula for the change of the dynamical horizon, we derive an equation for the mass incorporating the Hawking radiation. It is shown that final state is the Minkowski spacetime in our particular model.

Die geologischen Befunde werden daraufhin mit den Ergebnissen eines einfachen Modells der Atmosphäre für diese Zeit verglichen, das u. a. auf Paläothermo-Indikatoren beruht, aber unabhängig von Paläowind-Indikatoren formuliert wurde. Bezeichnend ist die Konkurrenz zweier Strömungsregime. In unmittelbarer Eisrandnähe sowie in Osteuropa sind anti-zyklonale Ost- bzw. Nordostwinde durch Paläowind-Indikatoren dokumentiert; in Mittel- und Westeuropa herrschten Westwinde als geologisch effektive Winde. Die Modellrechnungen weisen auf stärkeren Ostwindeinfluß. Die Unterschiede sind auf die unzureichende Kenntnis der thermischen Randbedingungen bei der Modellierung und auf die zeitliche Mittelung der Modellergebnisse zurückzuführen.

description: Inclusive charm meson production cross sections in the deep inelastic scattering and photoproduction regimes are compared with QCD leading and next-to-leading (NLO) calculations. The NLO predictions are significantly below the data in some parts of the measured kinematic range. Angular distributions of dijet events with charm show clear evidence for the existence of charm originating from the incoming photon. The charm fragmentation function is measured for the first time at HERA. Various fragmentation ratios and the fragmentation fractions of the low-lying charm hadrons are determined and compared to previous e+e- results.

CFF was recognized to be present in Suriname in 1986, but it appears to have been present since at least 1975. CFF originated in Asia, where it occurs in Indonesia, Malaysia and southern Thailand. Fifteen percent of Suriname's human population originated in Indonesia. Probably the CFF was introduced into the Western Hemisphere by persons traveling from Indonesia to Suriname. The spread of the CFF infestation and infested host plants were delimited soon after 1986. By 1990, the fly had spread throughout the northern (inhabited) part of Suriname and eastward into French Guiana. Subsequently the CFF spread westward to infest two border villages in Guyana, and, east of French Guiana, into the Brazilian State of Amapa. CFF's major hosts are carambola (Oxalidaceae: Averrhoa carambola L.) and curaçao apple (Myrtaceae: Syzygium samarangense (Blume) Merr. and Perry), which originated in Asia. Most tropical fruits are good hosts of CFF. In 1990 the first control actions were undertaken to prevent the fly from spreading westwards, and in 1997 a regional eradication program was initiated. The male annihilation technique (MAT) served as the main method for eliminating CFF populations. This technique involved the area-wide placement of 5 cm χ 5 cm χ 1 cm wood fiber blocks impregnated with methyl-eugenol mixed with malathion to lure and annihilate CFF males. Additional methods used were bait sprays, soil treatments, host fruit destruction, and pruning of host fruits. In urban areas the MAT technique was applied by spraying min-u-gel containing methyl eugenol and malathion onto tree trunks, electric-line poles etc. After good progress in freeing areas of CFF, the project closed in 2003 due to lack of funding, and by 2007 the CFF had reclaimed all cleared areas that had been infested at the initiation of the control project. In addition, the CFF has spread to new areas in Guyana. In the Brazilian State of Amapa, containment activities will continue relentlessly, due to the threat the pest represents to the Brazilian fruit industry. For Suriname, control of fruit flies in the future will have to include suppression of the CFF as one of the major economically important tropical fruit fly species. Alternative methods will be evaluated including biological control and localized application of bait sprays in fruit production areas. The establishment and expanding distribution of the CFF in the Guyana's represents a continuous threat to the fruit production in the Caribbean and the Latin American region.

description: Cogongrass is an aggressive, rhizomatous, invasive perennial grass that is scattered throughout the tropical and subtropical regions of the world, and has become a serious problem in Florida and other Gulf Coast States. A greenhouse study was conducted to evaluate the growth and spread of rhizomes of grass species grown in combination with other native grass species. Native grass species used included: switchgrass (Panicum virgatum L), maidencane (Panicum hemitomon Schult.), and muhlygrass (Muhlenbergia capillaries (Lam) Trin.). All plants were raised in tubbets and then transplanted to 7.6 L greenhouse pots in different combinations with cogongrass. Data on rhizomes of cogongrass and maidencane (rhizomatous species) were recorded during the harvest periods (6, 12, 18 or 24 weeks). The mean number and mean total length of cogongrass rhizomes ranged from 3 to 8 and 0.06 to 0.14 m at 6 weeks to 40 to 94 and 8.37 to 20.39 m at 24 weeks, respectively. Similarly, the mean number and mean total length of maidencane rhizomes ranged from 0.01 to 3 and 0.05 to 0.27 m at 6 weeks to 11 to 26 and 1.57 to 3.31 m at 24 weeks, respectively. There were 51 to 74% and 47 to 74% reductions in the mean total length of cogongrass rhizomes grown in combination than those grown individually at 12 and 18 weeks, respectively. The mean number of cogongrass rhizomes had 54 to 71% reductions when in combination than individually at 12 weeks. Likewise, at 18 weeks the mean number and mean total length of rhizomes of maidencane were reduced by 51 to 65% and 20 to 75%, respectively, when grown in combination with others grasses than alone. The number and spread of rhizomes explain cogongrass' invasiveness and competitiveness. The reduction of cogongrass in combination with native species shows a prospect that some Florida native grasses could reduce the invasiveness of cogongrass in the Gulf Coast States.
Havara on Cyprus - a surficial calcareous deposit

description: Havara ist eine Lokalbezeichnung für ein gelblich-weißes, hoch kalkhaltiges, klastisches, quartärzeitliches Lockergestein mit weiter Verbreitung auf Zypern. Die Korngröße ist vorwiegend Silt, reicht aber bis Kiesgröße. Der Steinanteil wechselt örtlich bedingt. Regional ist Havara an den Ausstrich kalkig-mergeliger mariner Gesteine des Oberen Maastrichts bis zum Pliozän gebunden, die große Teile Zyperns einnehmen. Genetisch ist Havara Hangschutt mit Anhäufung am Hangfuß. Am Ausgang von Hanghohlformen, Hangrissen und Tälchen ist er zu Schuttkegeln angehäuft und enthält dann vermehrt gröbere Steinanteile. Ebene oder schwach geneigte Flächen werden von dünneren, eher feinkörnigen Kalkstaub- und Kalksanddecken überkleidet. Vorwiegender Transporttyp ist deluvial durch Abspülung am Hang. Ungeregelte Massen mit groben Gesteinsanteilen müssen auch solifluktiv bewegt worden sein. Unter anthropogenem Einfluß (Hangbearbeitung, Beweidung) gesellt sich kolluviale Bewegung hinzu. Sturzschutt und äolische Sedimentation sind sehr untergeordnet. Der Aufschluß Kalavaôs-Márcou (Abb. 1), eine Hangfußakkumulation, erschließt rhythmisch geschichteten Havara mit gradierter Schichtung von grob-unten zu fein-oben mit jeweiligem humosen Bodenabschluß (schwache Rendzina). Zwei solcher Böden ergaben ein 14C-Alter an Holzkohlen von 31.970 a BP im tieferen Profilteil und 27.440 a BP im höheren Profilteil (Abb. 2), also ein Alter des Mittelwürms 4 sensu Schirmer 1991 (Tab. 1). Die terrestrische Havara-Boden-Abfolge drängt zum Vergleich mit den Löß-Boden-Rhythmen im Mittelwürm des Schwalbenbergs am Mittelrhein, die ihrerseits weltweit mit Klimarhythmen aus Eiskernen und Tiefseesedimenten korrelierbar sind (Schirmer 1995: 531). Aus der Tatsache, daß Havara heute in viel geringerem Maße, und dann meist durch anthropogene Rodung bedingt, abgelagert wird, und aus der Wechselfolge von Havara und Interstadialböden in mächtigen Havarapaketen läßt sich für die Havara-Bildung eine vegetationsärmere Zeit folgern als die heutige in Zypern. Der weltweite Klimawechsel Stadial/Interstadial findet also auch im terrestrischen Bereich des östlichen Mittelmeerraumes seinen Niederschlag durch vermehrte Hangaktivität mit Schuttproduktion in den Stadialen und Bodenbildung in den Interstadialen. Im Unterschied zu Havara ist Kafkalla ein Ergebnis der Bodenbildung: Kalkkrusten, Caliche. Sie entstehen durch deszendente Kalkfällung als Kalkknollen und Kalkstangen (Cc-Horizont), vorwiegend aber durch aszendente Kalkverkrustung der Oberfläche und schließlich lateralen Kalktransport in seicht gelegenen Grobsedimenten.

description: The advent of phenomenological quantum gravity has ushered us in the search for experimental tests of the deviations from general relativity predicted by quantum gravity or by string theories, and as a by--product of this quest the possible modifications that some field equations, for instance, the motion equation of spin--1/2--particles, have already been considered. In the present work a modified Dirac equation, whose extra term embraces a second--order time derivative, is taken as mainstay, and three different experimental proposals to detect it are put forward. The novelty in these ideas is that two of them do not fall within the extant approaches in this context, to wit, red--shift, atomic interferometry, or Hughes--Drever type--like experiments.

Problems of landslide chronology in the Mátra mountains in Hungary

description: Im letzten Jahrzehnt wurden bei der Untersuchung der Rutschungsprozesse und -formen in Ungarn in den Mittelgebirgen, die zumeist in der Mitte und am Ende des Miozäns entstanden sind, viele Rutschungsformen aufgenommen. Als Ergebnis der Geländeuntersuchungen kann festgestellt werden, daß diese Formen vor allem auf folgenden Gebieten vorkommen: a) in der Randzone der vulkanischen Gebirge, b) auf der steilen inneren Seite der Calderen der ehemaligen Ausbruchszentren, c) auf den Hängen der die schichtvulkanischen Strukturen tief ein- oder durchschneidenden Tälern. In den erwähnten charakteristischen Vorkommensbereichen stellen die Rutschungsformen einen wichtigen, an manchen Stellen einen entscheidenden Faktor des morphologischen Bildes dar. Die überwiegende Mehrheit der Formen ist heute nicht mehr aktiv, und die meisten von ihnen kann als fossil betrachtet werden. Deshalb ist es offensichtlich, daß die Rutschungsprozesse in der früheren Periode (oder in den früheren Perioden) eine wichtige Rolle in der Gestaltung der Form der Hänge spielten. Die bisherigen Forschungen gaben nur eine ziemlich unsichere, bloß prinzipielle Antwort auf die Frage nach der Entstehungszeit der Formen. Da die jungen Sedimente fehlen, konnte durch die gewöhnlichen stratigraphischen Methoden kein gutes Ergebnis erzielt werden, deshalb versuchten die Verfasser durch Bohrungen in den geschlossenen, abflußlosen - mit einem See oder Moor ausgefüllten - Eintiefungen der größeren Rutschungen die Aufschüttungsdauer der Eintiefungen, und dadurch das minimale Alter der Rutschungen zu bestimmen. Im Mátra-Gebirge wurde das Auffüllungsmaterial der Rutschungseintiefung untersucht. In manchen Fällen konnte eine Pollenanalyse durchgeführt werden, in zwei Bohrungen kam es auch zu einer 14C-Altersbestimmung. In der vorliegenden Studie werden die Ergebnisse der Bohrungen zusammengefaßt, und ausführlich werden die auch durch die 14C-Altersbestimmung unterstützten Pollendiagramme interpretiert. Die mit den verschiedenen Methoden durchgeführten Analysen zeigen, daß die Moorbildung in den untersuchten Fällen in der ersten Periode des Holozäns begann, und die Rutschungen erfolgten wahrscheinlich am Anfang der präborealen Zeit, oder früher, während einer Klimaverbesserung nach irgendeiner Kaltperiode der Spätglazialzeit. Die erhaltenen Ergebnisse können wohl auf die anderen - insgesamt etwa 20 - Rutschungsformen nicht extrapoliert werden, aber sie stellen doch eine Orientierungshilfe im Bezug auf ihr Alter dar.

Zur Altersstellung der Torfe und Gyttjen von Herxheim, Jockgrim und Rheinzabern in der Vorderpfalz

description: Die in den Tongruben Herxheim, Jockgrim und Rheinzabern vorkommenden Torfe und Gyttjen wurden pollenanalytisch untersucht, um dem immer noch nicht geklärten Datierungsproblem der dort angeschnittenen Pleistozänserien näher zu kommen. Für die Ablagerung der Herxheimer Torfe ergab sich eine subarktische Klimaphase, die den Beginn oder das Ende einer Warmzeit, aber auch ein Interstadial während einer Kaltzeit bezeichnen kann. Die nähere Zuordnung zu einem bestimmten Interglazial bzw. Glazial ist nach den pollenanalytischen Ergebnissen allein jedoch nicht möglich. Die Torfe und Gyttjen der nur wenige Kilometer voneinander entfernt liegenden Tongruben Jockgrim und Rheinzabern sind gleichaltrig. Die spurenweise in ihnen enthaltenen tertiären Gattungen Tsuga, Castanea, Pterocarya und Carya sowie auch Fagus sprechen für ein frühpleistozänes Alter der Torfe. Da aus dem süddeutschen Raum bisher noch keine vollständigen Pollendiagramme aus dem Altpleistozän vorliegen, ist die sichere stratigraphische Einordnung der Jockgrimer und Rheinzaberner Torfe vorläufig nicht möglich.

description: La cantidad de un elemento que la planta es capaz de absorber de un suelo ha sido objeto de numerosos estudios cientfficos. El Factor de Transferencia (FT) se define, conceptualmente, en la literatura cientifica, como la relaciôn entre la concentraciôn en la planta, ο en un ôrgano de ella, de un elemento determinado y la concentraciôn de ese elemento en el suelo. Esta defïniciôn desde una optica matemätica séria un modelo lineal muy simplista. Los modelos matemâticos que expresan los datos expérimentales del Factor Transferencia (FT) serän, por lo general, mäs complicados, pero siempre tienen la notable ventaja de ayudar a entender parte del proceso de traslocaciôn de los elementos nutritivos desde los suelos a las plantas cuantitativa y temporalmente. El objeto de este trabajo es estudiar en un cultivo de melocotones, Prunus persica L. los FT de los metales pesados mäs importantes cuando la solubilidad del suelo se altera por un proceso de correction de pH. Concluimos que los modelos de transferencia de metales pesados (Co, Cu, Ni y Zn) expresados por el valor de FT desde suelos calizos hacia las hojas en cultivos de melocotôn (Prunus persica L.) son por lo general modelos lineales. La mayoria de ellos salvo casos singulares como el Zn, ademäs, son modelos casi horizontales expresando el hecho de que las concentraciones de estos elementos en hojas son independientes de las concentraciones en el suelo, y que las alteraciones del pH modifica escasamente los valores de FT.
