A sequence of transcritical bifurcations in a suspension of gyrotactic microswimmers in vertical pipe

Abstract Kessler (Nature, vol. 313, 1985, pp. 218–220) first showed that plume-like structures spontaneously appear from both stationary and flowing suspensions of gyrotactic microswimmers in a vertical pipe. Recently, it has been shown that there exist multiple steady, axisymmetric and axially uniform solutions to such a system (Bees & Croze, Proc. R. Soc. A, vol. 466, 2010, pp. 2057–2077). In the present study, we generalise this finding by reporting that a countably infinite number of such solutions emerge as the Richardson number increases. Linear stability, weakly nonlinear and fully nonlinear analyses are performed, revealing that each of the solutions arises from the destabilisation of a uniform suspension. The countability of the solutions is due to the finite flow domain, while the transcritical nature of the bifurcation is because of the cylindrical geometry, which breaks the horizontal symmetry of the system. It is further shown that there exists a maximum threshold of achievable downward flow rate for each solution if the flow is to remain steady, as varying the pressure gradient can no longer increase the flow rate from the solution. All of the solutions found are unstable, except for the one arising at the lowest Richardson number, implying that they would play a role in the transient dynamics in the route from a uniform suspension to the fully developed gyrotactic pattern.
Comparative study of shell choice by the southern endemic hermit crab Loxopagurus loxochelis from Brazil and Argentina

Este estudio tuvo por objetivo determinar la forma de eleccion de conchas de caracoles por el cangrejo ermitano endemico del Atlantico sudoccidental Loxopagurus loxochelis proveniente de dos provincias biogeograficas de Brasil y Argentina. Se determinaron las tallas y las preferencias de conchas entre los dos tipos de caracoles mas ocupados (Olivancillaria urceus y Buccinanops gradatum) en la region de Caraguatatuba (Brazil) y en Mar del Plata (Argentina). La composicion de las conchas fue analizada por las caracteristicas biometricas y ocurrencia de los tipos de conchas y la seleccion por la preferencia del cangrejo ermitano en relacion a la especie de concha mas ocupada. Las muestras fueron tomadas usando redes de arrastre en las areas infralitorales de ambas regiones y los animales capturados fueron medidos y pesados. Las conchas de caracoles fueron identificadas, pesadas, medidas y calculado el volumen interno. Las experiencias fueron realizadas en acuarios donde los cangrejos ermitanos fueron ubicados con un numero suficiente y adecuado de conchas de caracoles. En el laboratorio, L. loxochelis de Argentina no presentaron diferencias entre las dos especies de conchas ofrecidas, mientras los especimenes de Brasil prefirieron conchas de B. gradatum en forma significativa. Se observo que las relaciones de las dimensiones y los pesos de las conchas fueron aquellas que mejor reflejaron la asociacion con los cangrejos ermitanos. Teniendo en consideracion que los especimenes de Argentina fueron mas grandes, se puede inferir que ello puede ser uno de los factores influenciando en las diferencias por las preferencias de los tipos de conchas halladas
The Effect of Cultural Values on Business Strategy Choices

The strategy is important in the effort to achieve firm performance. The decision of an entrepreneur in determining the choice of strategy is often influenced by certain factors. Ethnic cultural values embraced by an entrepreneur will often be an important issue that will have an impact on the choice of their business strategy. Therefore, this study aims to examine the effect of cultural values on business strategy choices. The study was conducted using quantitative methods using primary data through a survey on micro, small and medium business entrepreneurs in Palembang city. A total of 150 questionnaires were distributed to entrepreneurs. The number of questionnaires used in this study was 107 (71%). Structural Equation Modeling (SEM) Partial Least Squares (PLS) analysis using Warp PLS version 5.0 software is used to test the hypothesis. The results of the study indicate that the cultural values embraced by entrepreneurs influence the choice of business strategies that they implement.
Community composition and structure had no effect on forest susceptibility to invasion by the emerald ash borer (Coleoptera: Buprestidae)

Abstract Emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is a non-native, wood-boring beetle that has caused widespread mortality of ash (Fraxinus Linnaeus (Oleaceae)) in eastern North America. During 2004–2007, we determined whether forest community composition and structure of black (F. nigra Marshall), green (F. pennsylvanica Marshall), and white (F. americana Linnaeus) ash stands influenced their susceptibility to EAB invasion in southeast Michigan, United States of America. There was no relationship between EAB-induced ash decline or percentage mortality and any measure of community composition (tree species diversity, stand/ash density, total basal area, or relative dominance of ash). There was also no relationship between measures of EAB impact (density of EAB signs, ash decline rating, percentage ash mortality, or percentage infested ash) and forest attributes (ash/total stand density, basal area, ash importance, or stand diversity). Decline and mortality of black ash advanced more rapidly than that of white and green ash. Percentage mortality of ash increased from 51% to 93% during 2004–2007. Distance from the epicentre of the invasion was negatively correlated with ash mortality, but this relationship dissipated over time. Stand composition data suggests that ash will be replaced by Quercus Linnaeus (Fagaceae), Acer Linnaeus (Sapindaceae), and Tilia Linnaeus (Malvaceae); such vegetation changes will irreversibly alter the structure and function of these forests.
Differential predation of Welfia georgii seeds in treefall gaps and the forest understory

We report the results of an experimental study of predation by vertebrates on the seeds of the palm Welfia georgii in gaps and the forest understory of La Selva, Costa Rica. Seed survival in gaps and beneath fruiting adults was very low, and significantly less than survival in the understory 10 m from an adult. Thus, the increase in survival with dispersal of seeds away from the parent is habitat-dependent. This result is consistent with other studies in neotropical lowland wet forests, but contrasts with results from other geographical regions. The difference is likely caused by the differential responses of various seed predator species to treefall gaps.
IMPROVED METHOD FOR LARGE SCALE PURIFICATION OF THE PHOSPHOENOLPYRUVATE CARBOXYLASE OF ESCHERICHIA COLI K-12

A rapid and simple method for large-scale preparation of phosphoenolpyruvate carboxylase [EC 4.1. 1.31] from Escherichia coli K-12 was established. A strain carrying the ColE1-ppc+ (the gene of the enzyme) hybrid plasmid was used as an enzyme source. The cell-free extract was fractionated by ammonium sulfate, and the enzyme was purified to homogeneity by hydrophobic chromatography on hexyl-Sepharose using specific elution with L-aspartate, one of the allosteric effectors. The pure enzyme (153mg) was obtained from 137g wet cells in 4 days with 41% yield.
Acceptability of catechin and its oxidative condensation products to the rose aphid, Macrosiphum rosae

The rose aphid showed a significant level of nonpreference for concentrations of 0.3 mg/ml catechin and above, whether in a simple base diet of sucrose or a complex artificial diet containing in addition to other components a total amino acid content equivalent to that found in the sap pressed from the pedicels of rose‐buds. Similar concentrations of catechin were found in the pressed sap from pedicels of nonpreferred buds in the field. A number of factors influenced absolute values for deterrence: increased concentrations of sucrose and especially amino acids lowered the deterrence of catechin; early instars showed nonpreference for low concentrations of catechin that were nondeterrent to the later instars. A possible explanation for such variation was provided by discovery that the aphids were able to alter the phenolic composition of diets during feeding, converting catechin into condensation products that were either phagostimulant or nondeterrent.
TAXONOMIC SIGNIFICANCE OF NUCLEUS‐MICROBODY ASSOCIATIONS, SEGREGATED NUCLEOLI AND OTHER NUCLEAR FEATURES IN SIPHONOUS GREEN ALGAE 1

On the basis of fine‐structural features of nuclei the “true” siphonous green algae (Eusiphoniidae) are divided into three groups. In the Codium group nuclei are generally similar to those in most other algae. The Penicillus group is characterized by the association of microbodies with nuclei. In the Avrainvillea group nucleoli are segregated into a granular and a fibrillar component. This condition, known as macrosegregation, persists throughout the vegetative phase of the life history and may indicate a peculiar ribosomal RNA cycle.

Public Intention on Bandung Tour on Bus

Bandung is known as the capital of West Java. Bandung also develops as a culinary city. As a form of the Government's responsibility to facilitate tourists who come to Bandung, the Government has officially announced the "Bandros" Tourism Bus (Bandung Tour on Bus). But practically, there are many problems faced by stakeholders. Standardization of prices among passengers, limits on the number of buses that cannot serve passengers, unclear routes including departures and arrivals, unhealthy management for safety factors and an increase in the number of passengers that have a negative impact due to the quality of service. The purpose of this study is to describe service quality, community satisfaction and community interest in reusing Bandros, and also to obtain the results of an analysis of the extent to which service quality affects community satisfaction and its impact on community interest in reusing Bus Bandros. In this study, researchers used the descriptive-verification method. This method is used to verify the quality of service perception, community satisfaction and community intentions to reuse Bus Bandros by involving 500 respondents who wish to use Bus Bandros. The distribution and selection of respondents was carried out using convenience sampling. Path analysis is also used in this study. Based on the results of the statistical testing process found significant perceptions between service quality variables and brand image with public interest in the city of Bandung to use Bus Bandros. For recommendations in this study, clarity of information can increase the public's intention to use Bus Bandros, because the information submitted will provide clarity in order to increase public intention to ride Bus Bandros.
Epidemiology of Pythium damping-off and Aphanomyces root rot of peas after seed treatment with bacterial agents for biological control.

Field plots were established in 1989 and 1990 to investigate the efficacy of seed treatments with Pseudomonas cepacia strain AMMD, P. fluorescens strain PRA2S, Corynebacterium sp. strain SA, and captan on the epidemiology of root rot of pea caused by Aphanomyces euteiches and preemergence damping-off caused by Pythium spp. Disease incidence was assessed every 2-3 days, and soil-water matric potential and soil temperature were recorded. Strains AMMD and PRA2S significantly (P<0.05) suppressed initial disease 23-70% and the area under the disease progress curve 15-45% over both years compared to the nontreated control. Strain AMMD also suppressed the final incidence of disease at harvest by 11-19% over both years and PRA2S by 19% in 1989 compared to the nontreated control [. ]
Long‐trace interval eyeblink conditioning is impaired in mutant mice lacking the NMDA receptor subunit ε1

To elucidate the role of the N‐methyl‐d‐aspartate (NMDA) ‐type glutamate receptor subunit ε1 (GluRε1) in classical eyeblink conditioning, delay and trace eyeblink conditioning were investigated in GluRε1‐null mutant mice. In delay conditioning and short‐trace interval conditioning with a trace interval of 250 ms, GluRε1 mutant mice attained a normal level of the conditioned response (CR), although acquisition was a little slower than in wild‐type mice. In contrast, GluRε1 mutant mice exhibited severe impairment of the attained level of the CR and disturbed temporal pattern of CR expression in trace conditioning with a longer trace interval of 500 ms. These findings indicate that GluRε1 is essential for long‐trace interval eyeblink conditioning. The impairments of the associative learning with a long temporal separation between the conditioned and unconditioned stimuli observed in the GluRε1 mutant mice could be attributed to an impairment of hippocampal long‐term potentiation in this line of mutant mice.

The Effects of Plant Growth Regulators, Amino Acids and Minerals on Ethylene Biosynthesis and Evolution in 'Tsugaru' and 'Akane' Apple Fruit

The internal ethylene concentration (IEC), 1-aminocyclopropane-1-carboxylate (ACC) contents, N-malonyl-ACC (MACC) contents, ACC synthase activities, and ACC oxidase activities were determined on intact (early-maturing) and detached 'Tsugaru' and 'Akane' Apples to study the mechanism of ethylene biosynthesis. The effects of plant growth regulators, amino acids, and minerals on ethylene evolution by sliced and whole fruits were also examined. The IEC in 'Tsugaru' fruit rapidly increased from late August to September, reaching 300 μl·l-1 and 800 μl·l-1 in intact and detached fruit, respectively. In contrast, the attached fruit of 'Akane', IEC was only 5.6 μl·l-1 at its climacteric peak, whereas in detached fruits, it was less than 10 μl·l-1 during storage. ACC content and ACC synthase activity were both higher in 'Tsugaru' than they were in 'Akane' fruit. These results indicate that ethylene biosynthesis in both cultivars is regulated by ACC synthase activity, as reported previously for other cultivars, such as 'Fuji' and 'Senshu' (Suzuki, et al., 1997). Flesh slices dipped in 10 and 100 ppm GA3 had slightly reduced ethylene evolution. In whole fruit similarly treated with GA3, the ethylene evolution significantly decreased 2 weeks after treatment in comparison with the control ; the decrease continued throughout the treatment period. Treatment with 10 mM or 100 mM aspartic acid and 100 mM glutamine significantly reduced the ethylene evolution in sliced tissue, whereas 100 ppm Ca and NH4 -N tended to reduce ethylene evolution ; contrarily, the same treatments at 300 ppm stimulated it.
Fundamental Differences Between Conventional and Organic Tomato Agroecosystems in California

In an integrated, multidisciplinary study we compared ecological characteristics and productivity of commercial farms categorized as either organic (ORG) or conventional (CNV) based on their use of synthetic fertilizers and pesticides or reliance on organic soil amendments and biological pest control. We measured belowground parameters: various soil chemical and biological properties and root disease severity; common agronomic indicators: biomass, fruit yield and insect pest damage; and community level indicators, including arthropod diversity and soil microbial activity and diversity. CNV and ORG production systems could not be distinguished based on agronomic criteria such as fruit yield and arthropod pest damage levels. However, differences were demonstrated in many soil, plant, disease, and diversity indicators suggesting that the ecological processes determining yields and pest levels in these two management systems are distinct. In particular, nitrogen mineralization potential and microbial and parasitoid abundance and diversity were higher in ORG farms. Differences between the agroecosystems were sufficiently robust to be distinguished from environmental variation and suggest that biological processes compensated for reductions in the use of synthetic fertilizers and pesticides.
An experimental study of the early weaning of lambs

Two early weaning experiments are reported. When grazing young, high protein pastures, lambs weaned at 7, 10, 13 and 18 weeks of age grew equally well and there were no significant differences between their carcass weights, grades, and dressing percentages. However, when grazing pastures in the preflowering and flowering stages of growth, lambs weaned at 8 weeks of age did not grow as well as unweaned controls. Their carcass weights, grades, and dressing percentages were also inferior. It is suggested that these differences were primarily due to an inadequate protein intake. No difference in wool production was found either between the ewes of early weaned and control lambs, or between the lambs themselves.
The origins of molluscs

The interrelationships and evolutionary history of molluscs have seen great advances in the last decade. Recent phylogenetic studies have allowed alternative morphology‐based evolutionary scenarios to be tested and, most significantly, shown that the aplacophorans are sister group to polyplacophorans (chitons), corroborating palaeontological and embryological evolutionary scenarios in which aplacophorans are secondarily simplified from a chiton‐like ancestor. Aplacophoran morphology therefore does not represent the plesiomorphic condition for molluscs as a whole. The mollusc crown group radiated in the Early Cambrian, and rapidly thereafter, stem lineages to the major molluscan classes emerged: cephalopods, gastropods, bivalves (= pelecypods), monoplacophorans, rostroconchs (inferred stem scaphopods) and aculiferans. This attests to the fast, adaptive radiation of the crown group during the Cambrian explosion. Kimberella from the latest Ediacaran exhibits several molluscan traits, which justifies its position as a molluscan stem‐group member, rather than as a more basal Lophotrochozoan. The interrelationships among the conchiferan molluscs are still a matter of contention and require further palaeontological and molecular phylogenetic scrutiny.
Upregulation of long noncoding RNA RAB11B-AS1 promotes tumor metastasis and predicts poor prognosis in lung cancer

Background Lung cancer (LC) is one of the leading causes of cancer-related mortality in China and worldwide. Despite the progress in diagnosis and treatment of LC, the prognosis of LC remains poor. Studies have demonstrated that long non-coding RNAs (lncRNAs) play a critical role in carcinogenesis and cancer development. Methods Here we examined the expression and potential function of lnc-RAB11B-AS1 in LC both in vitro and in vivo. All experiments in this study were conducted using A549 and PC-9 cell lines according to protocols described in this paper. The clinic characteristics were analyzed using logistic regression, cox model, log rank test, biochemical analysis using qRT-PCR, transfections, nude mice model, and cell biological analysis using Transwell assay, CCK-8 assay, flow cytometry, and rescue experiments, and immunohistochemistry. Results The results showed that lnc-RAB11B-AS1 was significantly overexpressed in LC tissues compared to the corresponding non-tumor tissues. Patients with a higher level of lnc-RAB11B-AS1 expression showed a poorer overall survival rate. Functionally, overexpression of lnc-RAB11B-AS1 promotes cell proliferation, migration and invasion abilities of LC cell lines, which suggests lnc-RAB11B-AS1 may play an oncogenic role in LC. lnc-RAB11B-AS1 was located in physical contiguity with RAB11B gene and found positively regulates the RAB11B expression, and the protein levels of RAB11B in LC tissues also found to positively correlated with the level of lnc-RAB11B-AS1 expression. RAB11B silencing partially abrogated lnc-RAB11B-AS1-induced proliferation of the LC cell lines used in this study. Conclusions This study provided a novel evidence into the function of lncRNA-driven carcinogenesis. Our findings highlighted the importance of lnc-RAB11B-AS1 and RAB11B in LC progression and indicated that lnc-RAB11B-AS1 may serve as a novel and valuable prognostic biomarker for LC.
Effect of Problem-Based Learning on Students’ Academic Achievement in Digital Electronics in Ken Saro-Wiwa Polytechnic, Bori, Rivers State, South-South, Nigeria

The study investigated the effect of Problem-Based Learning (PBL) on Students’ Academic Achievement in Digital Electronics in Ken Saro-Wiwa Polytechnic, Bori, Rivers State, South-South, Nigeria. Quasi-experimental pre-test post-test control design was used in the study. The sample of the study comprised 84 Higher National Diploma (HND) final year students of electrical and electronic engineering (Telecommunications and electronics option). Three research questions and one hypothesis were formulated and tested at 0.05 level of significance guided the study. The instrument used for data collection was a 20-item Digital Electronics Achievement Test Questionnaire (DEATQ) designed by the researcher and validated by two experts in electrical and electronic engineering from Federal Polytechnic, Nekede, Owerri, Imo State. Kuder-Richardson formula was used to obtain the instrument’s reliability coefficient as 0.87. Mean and t-test were used to answer the research questions and test the hypothesis at 0.05 level of significance. The findings of the study revealed among others that problem-based learning enhances students’ academic achievement in Digital Electronics. Consequently, it was recommended among others that engineering technology lecturers in Nigerian polytechnics and universities should use more of PBL and other student-centred teaching strategies in instructional delivery in order to boost students’ achievement in technology-based courses.
