Methods for Growing Tintinnida in Continuous Culture

A continuous—flow culturing apparatus was developed for rearing Tintinnida. Control over the yield of protozoa is through adjustment of both the food input and the flow rate. The maximum sustained output of Tintinnopsis beroidea approached 103 cells/ml, and higher yields are believed possible. The advantages of the apparatus for ecological investigations, and the required modifications for analysis of tintinnid trophodynamics, are discussed.
Experiences of Veterans with ICD-11 Complex PTSD in Engaging with Services

Abstract This study aimed to examine how UK military veterans with complex post-traumatic stress disorder (CPTSD) engage with psychological services. Qualitative interviews were conducted with eight veterans with CPTSD. Data were analyzed using thematic analysis. UK veterans with CPTSD were found to experience a number of barriers in accessing and engaging with mental health services. That certain CPTSD symptoms (e.g., negative self-concept) may act as a deterrent to help-seeking warrants further exploration in future help-seeking initiatives to ensure that those with CPTSD are able to access appropriate care.
BMIAE: blockchain-based multi-instance Iris authentication using additive ElGamal homomorphic encryption

Multi-biometric systems have been widely accepted in various applications due to its capability to solve the limitations of unimodal systems. Directly storing the biometric templates into a centralised server leads to privacy concerns. In the past few years, many biometric authentication systems based on homomorphic encryption have been introduced to provide security for the templates. Most of the existing solutions rely on an implication of the assumption that the server is ‘honest-but-curious’. Therefore, the compromise of server results into the entire system vulnerability and fails to provide the integrity. To address this, we propose a novel multi-instance iris authentication system, BMIAE to deal with malicious attacks over the transmission channel and at the untrusted server. BMIAE encrypt the iris templates using ElGamal encryption to guarantee confidentiality and Smart contract running on a Blockchain helps to achieve the integrity of templates and matching result. BMIAE also addresses the limitations of using Blockchain for biometrics like privacy and expensive storage. To check the effectiveness and robustness, BMIAE has experimented on CASIA-V3-Interval, IITD and SDUMLA-HMT iris databases. Experimental results show that BMIAE provides improved accuracy, and eliminates the need to trust the centralised server when compared to the state-of-the-art approaches.
A procedure to measure amylose in cereal starches and flours with concanavalin A.

A modified procedure for the determination of amylose in cereal starches and flours based on complex formation between the lectin concanavalin A (Con A) and amylopectin has been developed and characterised. The assay format is suitable for multi-sample analysis, allowing the analysis of up to 20 samples per day. In the procedure, the amylopectin in a solubilised, lipid-free starch sample is precipitated by reaction with Con A and removed by centrifugation. The amylose remaining in the supernatant is then determined after amylolytic hydrolysis to glucose and expressed as a proportion (%) of the glucose derived from amylolytic hydrolysis of the total starch in a separate aliquot of the solubilised sample (i.e. prior to Con A treatment). The Con A procedure correlates well (r>0·993) with existing Con A-based and iodine-based procedures and yields a linear standard curve for starch samples containing from ∼0 to ∼100% amylose. Advantages of this modified Con A procedure for amylose determination include its applicability to flour samples without the need for prior starch purification; it allows the simultaneous estimation of total starch and does not require a calibration curve. Repeated analyses of a set of samples yielded repeatability (within laboratory) relative standard deviations of <5% for pure starches and ∼10% for flours. A commercially available assay kit has been developed to facilitate the use of the Con A procedure in routine amylose determinations.
Studies of χ(2)/χ(3) Tensors in Submicron-Scaled Bio-Tissues by Polarization Harmonics Optical Microscopy

Optical second- and third-harmonic generations have attracted a lot of attention in the biomedical imaging research field recently due to their intrinsic sectioning ability and noninvasiveness. Combined with near-infrared excitation sources, their deep-penetration ability makes these imaging modalities suitable for tissue characterization. In this article, we demonstrate a polarization harmonics optical microscopy, or P-HOM, to study the nonlinear optical anisotropy of the nanometer-scaled myosin and actin filaments inside myofibrils. By using tight focusing we can avoid the phase-matching condition due to micron-scaled, high-order structures in skeletal muscle fibers, and obtain the submicron-scaled polarization dependencies of second/third-harmonic generation intensities on the inclination angle between the long axes of the filaments and the polarization direction of the linear polarized fundamental excitation laser light. From these dependencies, detailed information on the tensor elements of the second/third-order nonlinear susceptibilities contributed from the myosin/actin filaments inside myofibrils can thus be analyzed and obtained, reflecting the detailed arrangements and structures of the constructing biomolecules. By acquiring a whole, nonlinearly sectioned image with a submicron spatial resolution, we can also compare the polarization dependency and calculate the nonlinear susceptibilities over a large area of the tissue at the same time—which not only provides statistical information but will be especially useful with complex specimen geometry.

Summary L'accroissement de production des tomates (Lycopersicon esculentum Mill.) de conserverie en semis direct et l'utilisation d'herbicides selectifs ont entraine la proliferation de Solanum nigrum L. dans le Sud-est de la France. Les estimations realisees sur le terrain ont montre l'action prejudiciable de faibles populations de morelles; un essai a ete mis en place afin de determiner un seuil de nuisibilite. Dans les conditions d'essai, une droite de regression a pu etre tracee en fonction de la densite de morelle/m lineaire et du logarithme du rendement. Resume Preliminary studies on competition between Solanum nigrum ssp. eu-nigrum L. (black nightshade) and transplanted Lycopersicon esculentum Mill, (tomato) The increasing production of direct-seeded tomatoes (Lycopersicon esculentum Mill.) and the use of selective herbicides have caused a proliferation of Solanum nigrum in south-east France. Field evaluations showed that even low populations of S. nigrum caused severe reduction of yield. In a test of levels of damage, a linear regression of density of S. nigrum on the logarithm of the yield of tomatoes was obtained. Zusammenfassung Vorlaufige Untersuchungen zur Konkurrenz zwischen Solanum nigrum ssp. eu-nigrum L. (Schwarzer Nachtschatten) und verpflanzten Tomaten (Lycopersicon esculentum Mill.) Die zunehmende Produktion von direkt-gesaten Tomaten (Lycopersicon esculentum Mill.) fur die Konservenindustrie und die Verwendung selektiver Herbizide haben in Sudost-Frankreich zu einer Vermehrung von Solanum nigrum L. gefuhrt. Felderhebungen zeigten, dass sogar geringe Dichten von S. nigrum erhebliche Ertragsreduktionen verursachen. Unter den untersuchten Bedingungen bestand eine lineare Beziehung zwischen der Dichte von S. nigrum und dem Logarithmus des Tomatenertrags.
Limnological succession in reservoirs: a paleolimnological comparison of two methods of reservoir formation

Analysis of diatoms, algal pigments, and chironomids in sediment cores from two otherwise similar prairie reservoirs demonstrated that differences in reservoir formation (river valley impoundment versus lake inundation) and hydrological regime (variable versus stable water level) resulted in distinct patterns of aquatic community change. Lake Diefenbaker, a 500-km2 reservoir created by damming the South Saskatchewan River in 1968, experiences water level fluctuations of 6 m·year-1. In contrast, impoundment of Buffalo Pound Lake in 1952 flooded a natural lake, raised mean water levels ~2.0 m, and reduced water level fluctuations from ~3 to <1 m·year-1. Comparison of fossil records showed that reservoir formation did not inevitably lead to eutrophication. Lake Diefenbaker exhibited typical reservoir ontogeny with three trophic periods, including an initial ~4-year period of eutrophy, a decade of mesotrophy, and a gradual shift to modern productive conditions. Planktonic taxa dominated diatom communities at .
Historical biogeography of lowland species of toads (Bufo) across the Trans‐Mexican Neovolcanic Belt and the Isthmus of Tehuantepec

Aim In this study, we investigate phylogeographic structure in two different species groups of lowland toads. First, we further investigate strict parapatry of the Pliocene‐vicariant Bufo valliceps/B. nebulifer species pair. Secondly, we test for similar phylogeographic structure in the distantly related toad B. marinus, a species we hypothesize will show a Pleistocene dispersal across the same area.
Adaptability of tissue-cultured Dendrobium orchid planlets on planting media and its position during acclimatization process

The acclimatization process of cultured plants needs special attention because it is a critical period for adaptation to In-Vivo conditions. The environmental changes and the imperfection of planlet anatomy are important things that need to be considered to support the growth of Dendrobium orchid planlet. The aim of this study was to determine the effect of planting media type and its positioning on the Dendrobium orchid adaptability during acclimatization process. This study was conducted from March to Mei 2017 in AIAT North Sumatra tissue culture laboratory and screen house. The experimental design used in this study was a randomized group design with five replications. The treatment consisted of planting media and pot position model. The planting media combination were fern+wood charcoal (M0); fern+coconut fibre (M1); ferns+broken bricks (M2); fern+wood charcoal+coconut fibre (M3); and ferns+wood charcoal+coconut fibre+broken bricks (M4) while the pot position model were laying (P0) and hanging (P1) model. Morphological parameters observed were growing plant percentage, plant height, leaves number, roots number, and roots length. The results showed that the best planting media and pot position combination supported the Dendrobium orchid growth were found in ferns and wood charcoal (M0) and ferns and bricks (M2) with lying model (P0).
RÉPARTITION SPATIO-TEMPORELLE DE LA GRANDE ALOSE ALOSA ALOSA (LINNÉ, 1766) ET DE L'ALOSE FEINTE ALOSA FALLAX (LACÉPÈDE, 1803) DANS LE GOLFE DE GASCOGNE.

Ce travail sur la distribution en milieu marin de la grande alose Alosa alosa et de l’alose feinte Alosa fallax, au niveau du plateau continental oceanique francais de l’Atlantique Ouest, s’est appuye sur les donnees de captures collectees pendant pres de 3 ans, entre aout 1986 et mars 1989, par trois types de campagnes experimentales de chalutage menees par l’IFREMER (Institut Francais de Recherche pour l’Exploitation de la Mer). Au vu de l’aire echantillonnee qui s’etend de l’ile d’Ouessant jusqu’au Gouf de Capbreton (latitudes 48°30’ N – 43°45’ N) de la cote jusqu’a plus de 700 m de profondeur au large (longitudes 4° W – 1°20’ W), Alosa fallax frequente particulierement les zones de moins de 50 m de profondeur et ne depasse pratiquement pas l’isobathe des 100 m contrairement a Alosa alosa qui se repartie de maniere plus uniforme jusqu’a des fonds de plus de 100 m. Leur distribution est de type agregatif, en panache autour des embouchures des principaux bassins versants d’accueil (Gironde, Loire). Chez les deux especes, et particulierement pour l’alose feinte, les individus de plus grande taille sont rencontres dans les zones les plus profondes. L’amplitude des âges varie de 2 a 5 ans chez A. alosa et de 2 a 6 ans chez A. fallax. Sur l’ensemble des campagnes, 89 a 95 % des individus A. alosa appartiennent a la classe d’âge des 2 et 3 ans et 85 a 92 % des A. fallax ont entre 3 et 4 ans. La quasi absence de jeunes A. fallax âges de 2 ans confirme une infeodation plus forte aux milieux estuariens a ce stade. En comparant les caracteristiques biometriques d’A. alosa âgees de 2 ans provenant d’une part de l’estuaire de la Gironde et d’autre part du milieu marin, il apparait que le coefficient de condition des premiers est significativement plus eleve. Le temps d’adaptation necessaire au passage d’un milieu estuarien riche en proies a un milieu marin offrant de nouvelles conditions peut expliquer une perte d’embonpoint.
Nutritive value and rumen fermentability characteristics of the diet were supplemented by dried carboxylate salts mixture (DCM)

The objective of this study is to determine the effect of supplementation of a mixture of dried carboxylic salt (DCM) protected by fatty acids in fermented feed on nutritional values and fermentation characteristics and ammonia concentration. Rumen liquid, sago waste, rice bran, fish waste, and sap liquid are used as material. The total ration mixture formulation is based on fermented feed and DCM supplements as follows: R0 (40% rice bran, 40% fermented sago waste, 20% tofu waste R1 (40% fermented rice bran, 40% fermented sago waste, 20% commercial concentrate), R2 (R1 + 1.5% DCM) R3 (R1 + 3% DCM) and R4 (R1 + 4.5% DCM) The nutritional value of fermented feed obtained by DCM supplementation was significantly different between treatments, supplementation 1.5-4.5% DCM significantly increased dry matter, ash, and ether extract. DCM supplementation significantly reduced crude fibre and not in crude protein. The addition of DCM increases the dry matter, ash, and ether extract and decreases crude fibre and does not affect the crude protein. The addition of DCM in ration decreases rumen pH but increases total VFA and N-NH3 ammonia concentration.
Antitumor, Antioxidant, and Antibacterial Activities of Glycosyl-Conjugated Compounds: A Review

There is a developing interest for the utilization of glycosyl-conjugation to improve the biological and pharmacokinetic properties of different medicinally active products. This is manifested by the presence of a significant number of research papers concerning the boosting of various therapeutic potentials of known drugs by their conjugation with different mono-, di-, or poly-saccharides. This review summarizes the most important and most recent examples of this conjugation, especially those related to the enhancement of antitumor, antioxidant and antibacterial activities of the original drugs. These examples with the proposed mechanisms of activity improvement may guide to design, synthesis and evaluation of new glycosyl-conjugates for better therapeutics.
Wave height prediction of Beibu Gulf based on convolution neural network

The wave state plays a vital role in the planning of marine activities. Predicting the wave significant height can prepare for the abnormal sea state in advance, which is of crucial influence to the marine activities. Unlike other scholars in the field of ocean research, this paper starting with analyzing artificial neural network model. By using the convolution neural network to model the measured wave height historical data, and to predict the ocean wave situation in the next six hours based on the measured data of wave height in the Beibu Gulf sea area. Using MAE, RMSE, PCC and etc. error evaluation methods, analyse the influence of convolution neural network on wave height prediction results in different layers is discussed and analyzed under different historical data input conditions. Finally, the network model is trained with the measured data in November and December 2018, and the results are analysed and compared.
Role for Interferon‐γ in the Immunomodulatory Activity of Human Bone Marrow Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) inhibit the proliferation of HLA‐unrelated T lymphocytes to allogeneic stimulation, but the mechanisms responsible for this activity are not fully understood. We show here that MSCs suppress the proliferation of both CD4+ and CD8+ T lymphocytes, as well as of natural killer (NK) cells, whereas they do not have an effect on the proliferation of B lymphocytes. The antiproliferative effect of MSCs was not associated with any effect on the expression of cell‐activation markers, induction of cell apoptosis, or mimicry/enhancement of T regulatory cell activity. The suppressive activity of MSCs was not contact‐dependent and required the presence of interferon (IFN)‐γ produced by activated T cells and NK cells. Accordingly, even activated B cells became susceptible to the suppressive activity of MSCs in the presence of exogenously added IFN‐γ. The suppressive effect of IFN‐γ was related to its ability to stimulate the production by MSCs of indoleamine 2,3‐dioxygenase activity, which in turn inhibited the proliferation of activated T or NK cells. These findings suggest that the beneficial effect on graft‐versus‐host disease induced by in vivo coinfusion with the graft of MSCs may be due to the activation of the immunomodulatory properties of MSCs by T cell– derived IFN‐γ.
Exhaustive and informatics-aided search for fast Li-ion conductor with NASICON-type structure using material simulation and Bayesian optimization

Currently, NASICON-type LiZr2(PO4)3 (LZP)-related materials are attracting attention as solid electrolytes. There are experimental reports that Li-ion conductivity can be improved by doping a small amount of Ca or Y into stoichiometric LZP. In previous studies, doping with only one element having a narrow search space has been attempted, and thus, further improvement of the Li-ion conductivity is conceivable by using multi-element doping. When multi-element doping is attempted, because the search space becomes enormous, it is necessary to evaluate the Li-ion conductivity using a low-cost method. Here, force-field molecular dynamics using a bond valence force field (BVFF) approach was performed to evaluate the Li-ion conductivity. We confirmed that the Li-ion conductivity of stoichiometric LZP derived from BVFF (6.2 × 10−6 S/cm) has good agreement with the first principle calculation result (5.0 × 10−6 S/cm). Our results suggest that the Li-ion conductivity can be further improved by simultaneously doping LZP with Ca and Y [6.1 × 10−5 S/cm, Li35/32Ca1/32Y1/32Zr31/16(PO4)3]. In addition, Bayesian optimization, which is an informatics approach, was performed using exhaustively computed conduction property datasets in order to validate efficient materials search. The averages for Bayesian optimization over 1000 trials show that the optimal composition can be found about seven times faster than by random search.
The Fundamental-to-Market Ratio and the Value Premium Decline

Recent evidence indicates the value premium declined over time. In this paper, we argue this decline happened because book equity, BE, is no longer a good proxy for fundamental equity, FE, defined as the equity value originating purely from expected cash flows (i.e., no discount rate differences across firms). Specifically, we estimate FE for public US firms (from 1973 to 2018) and find that the premium associated with the fundamental-to-market ratio, FE/ME, has been large and stable while the cross-sectional correlation between FE/ME and BE/ME decreased over time, inducing an apparent decline in the value premium. Our results echo recent findings in the corporate finance literature
Isolation of Residual Nuclear Structures from Microsporocytes of Trillium kamtschaticum.

Residual nuclear structures were isolated from Trillium microsporocytes at early meiotic prophase. Relatively well conserved residual nuclear structures were obtained from nuclei isolated in buffer containing 0.1 mM CUSO4. These isolated nuclei were treated with DNaseI, then their chromatin were extracted with 2 M NaCl or dextran sulfate combined with heparin. Cytological and biochemical estimations of the effectiveness of 2 M NaCl and dextran sulfate-heparin on chromatin extraction showed the latter to be the more effective agent. Light microscopy revealed that the residual nuclei retained silver-stainable structures that corresponded to synaptonemal complexes (SCS). The residual nuclei prepared by the treatment with dextran sulfate-heparin consisted mainly of protein that was about 8% of the total nuclear protein present, whereas, about 30% of the nuclear protein was re-tained by nuclei treated with 2 M NaCl.
Analysis of agonism by dopamine at the dopaminergic D 2 G-protein coupled receptor based on comparative modelling of rhodopsin

A number of theoretical dopaminergic D 2 models were constructed using comparative modelling techniques. The models constructed were based on the recently published crystal structure of rhodopsin. D 2 models were constructed without any ligands bound in the active site and also with the endogenous agonist, dopamine, bound in the active site. Comparison of the bound and unbound models revealed the importance of the chi angle of serine 197 and the effect this has on the bending of helix 5 when an agonist is present in the binding site.
Myxosoma cerebralis: Trypsinization of Plankton Centrifuge Harvests Increases Optical Clarity and Spore Concentration

Pepsin, pronase, and trypsin were compared for their ability to digest the tissue residues that constitute the overwhelming mass of plankton centrifuge harvests. Trypsin was preferred; a treatment with 0.25% for 30 min at pH 7.2–7.5 released an average of 22% additional spores and resulted in an average 11-fold increase in spore concentration. The procedure significantly enhances the sensitivity of spore detection by the plankton centrifuge method.Key words: Myxosoma cerebralis, myxosporidans, spore detection
Communicative institutionalization of CSR: a content analysis of firms’ motivations in social reports from three market economies

ABSTRACT Drawing on institutional theory, this content analysis explored firms' social reports for a ten-year period in three market economies. Specifically, this study analyzed firms' motivations for corporate social responsibility (CSR) through a proxy of the salience of stakeholder groups in social reports. First, firms' competitive motivations for CSR were significantly higher in the stated-led market economies (SLMEs: France, South Korea) than in the liberal market economies (LMEs: US, UK), which showed the lowest level of firms' competitive motivations for CSR during all investigated periods. Secondly, firms' socially cohesive motivations for CSR significantly decreased over time in SLMEs only, while increasing in LMEs and the coordinated market economies (CMEs: Germany, Japan). Theoretical and practical implications are discussed in terms of the constitutive role of communication in the institutionalization of CSR.
