Changes in the processing quality of sugar beet (Beta vulgaris L.) during long-term storage under controlled conditions.

Summary Long-term storage of sugar beet is an option to extend the processing campaign of the sugar factories in Europe. In the present study, changes in the processing quality of sugar beet were quantified during 110 days of storage at 7 and 20 °C. During storage, the concentration of sucrose decreased whereas K, Na, amino N, betaine, invert sugar and raffinose accumulated in the beets, i.e. quality was impaired markedly. At 7 °C, the changes in sucrose concentration were relatively small but the formation of invert sugar and raffinose caused considerable losses in beet quality. Thus, long-term storage at low temperature is appropriate to prolong the campaign but processing costs will increase. Quality assessment with two formulae showed that measurements of K, Na and amino N are insufficient to evaluate stored sugar beets for recoverable sugar. Due to its increase in storage, the concentration of invert sugar should also be taken into account.
Plasma amino acid curve in rats force-fed a single meal lacking an essential amino acid

The amino acid levels in plasma and liver were determined in rats at various time intervals after giving the animals a single meal of a complete amino acid diet (CAA) or a diet devoid of either leucine, isoleucine, or threonine. Male rats were fed by stomach tube and they were killed at 0, 2, 4, 6, or 8 hours postprandial. Amino acid analyses were performed on deproteinized supernatants of plasma and liver. The changes in the plasma amino acid levels occurred within 2 hr after feeding a single meal of either the diet lacking leucine or CAA. The values of most of the amino acids attained their highest levels at 4 hr postprandial and many amino acids were declining in concentration at 6 and 8 hr. Isoleucine and valine showed very high levels in plasma at 2, 4, 6 and 8 hr after feeding the diet devoid of leucine. The amino acid levels in liver reflected the amino acid concentrations in plasma at each time interval. Rats fed the diets devoid of either isoleucine or threonine demonstrated less alterations in plasma amino acid concentrations with only a few amino acids changed. After giving a single meal the amino acid levels in plasma are transient since many of the amino acids show similar values at the 0- and 8-hr intervals. The alterations in amino acid levels in plasma that occur after feeding are dependent upon both the identity of the essential amino acid omitted from the diet and the postprandial time. Am. J. Clin. Nutr. 26: 1175-1179, 1973.
Overinvestment, Corporate Governance, and Dividend Initiations

Firms with low Tobin's Q and high cash flow have significantly more positive dividend initiation announcement returns than do other firms. I interpret this result as consistent with the hypothesis that reductions in the agency costs of overinvestment at firms with poor investment opportunities and ample cash flow are reflected in higher dividend initiation announcement returns. Further tests, such as examining the impact of governance metrics on initiation announcement returns following the dividend tax cut of 2003 and examining the long-run cash-retention policies of dividend-initiating firms, are consistent with this interpretation. There is also some evidence that is consistent with the cash flow signaling hypothesis, as dividend-initiating firms with low Tobin's Q and low pre-initiation cash flow experience substantial revisions in analysts' earnings forecasts and significantly positive initiation announcement returns.
Common mental disorders among workers in the urban area of Feira de Santana - Bahia-Brazil

OBJECTIVE: To estimate the prevalence of common mental disorders (CMD) among workers in Feira de Santana city, Bahia, Brazil, according to sociodemographic characteristics, occupation, work psychosocial aspects, and leisure activities. METHODS: Exploratory cross sectional study, with random sampling of workers of Feira de Santana. A structured questionnaire on sociodemographic characteristics, professional work, psychosocial aspects at work, and leisure activities have been used in 2002. CMD was evaluated by using the SRQ-20. Logistic regression techniques were used to analyze the association between CMD and the variables of interest. RESULTS: 1.311 workers have been studied and the prevalence of CMD was 25.2%. The characteristics statistically associated to CMD, in the final model of analysis, were: female (PR=3.04; 2.34-3.95), low education level (PR=2.02; 1.57-2.60), low monthly income (PR=1.78; 1.12-2.84), absence of leisure activities (PR=1.35; 1.10-1.66), and work with high psychological demand (PR=1.45; 1.14-1.84). CONCLUSION: Association between CMD and several sociodemographic characteristics have been evidenced. Special attention must be given to these characteristics in order to promote worker's mental health.
Loss of Seed Buoyancy in Hibiscus glaber on the Oceanic Bonin Islands

Abstract: The Bonin (Ogasawara) Islands are subtropical oceanic islands in the northwestern Pacific. Reflecting their ancient origins, previous studies on plants of the Bonin Islands reported evolutionary phenomena that are common to oceanic islands, such as high endemism and accelerated diversification. In this article, we demonstrate the first example of loss of seed dispersibility during the evolutionary processes of the plants of the Bonin Islands. Seed buoyancy and morphology of Hibiscus glaber, a tree endemic to the Bonin Islands, and H. tiliaceus, a pantropic species, were examined. The latter is the progenitor species of H. glaber. Average ratios of floating seeds per tree were 0.2 and 0.8 for H. glaber and H. tiliaceus, respectively, in a 3% NaCl solution. There was considerable variation among individual H. glaber trees, ranging from 0 to 0.89. The air space inside the seed coat was generally smaller in H. glaber than in H. tiliaceus. Loss of seed buoyancy in H. glaber is due to decreased air space in the seeds. It is plausible that loss of seed buoyancy occurred in response to the habitat shift inland during the speciation process of H. glaber from the coastal species H. tiliaceus.
Observations on the Relationship Between Above- and Below-Ground Anthocyanin Production in Galax urceolata (Poir.) Brummitt Growing in Sun-Exposed and Shaded Locations

Abstract Galax urceolata (Diapensiaceae) is a common evergreen herb of southern Appalachian forests. During the fall and winter, leaves of plants in high light produce substantial amounts of anthocyanins. Oddly, rhizomes in these plants also accumulate anthocyanins. The purpose of this observational study was to identify seasonal trends in anthocyanin production in above- and below-ground tissues of Galax. We measured anthocyanins and chlorophyll in Galax using standard extraction and spectrophotometric procedures from plants in sun-exposed and shaded locations; one population at Mount Jefferson State Natural Area in fall 2007 and two at Grandfather Mountain in fall/winter 2008–09. Rhizome carbohydrates (soluble sugars and starch) were measured from the Grandfather populations using high performance liquid chromatography. We found significantly more anthocyanins in leaves and rhizomes of plants from sun-exposed locations compared to plants from shaded locations, but no differences in carbohydrate concentrations. Starch levels declined significantly through the fall/winter of 2008–09, while soluble sugars, such as sucrose, raffinose, and fructose, increased. Rhizomal anthocyanins were distributed throughout the entire cross-section except for the vascular tissues, whereas in petioles and leaves, they were restricted to the epidermal or subepidermal layers. Rhizomal anthocyanins often concentrated around lateral roots as they penetrated the cortex. These results contradict the paradigm that light is always required for anthocyanin production, and suggest the possibility of some form of communication between leaves and rhizomes with respect to anthocyanin content, although the nature of that signal is unknown. At this time, the adaptive significance of below-ground anthocyanins in Galax remains unresolved.
Utilization of Exogenous Carbohydrates for Tube Growth and Starch Synthesis in Pine Pollen Suspension Cultures

Pine pollen (Pinus mugo) grown in suspension cultures readily utilize exogenous carbohydrates for tube growth and starch synthesis: these processes are not influenced by β-indolylacetic acid, gibberellic acid, kinetin and abscisic acid. It appears that the free sugars of the female gametophyte, namely sucrose, raffinose, and stachyose and their monosaccharide constituents, are the best substrates for growth and polysaccharide synthesis. The oligosaccharides are hydrolysed to their monosaccharide constituents before they are taken up. A preferential uptake of fructose is noted. Non-metabolizable sugars are not taken up. The data presented establish that tube growth, except for the initial growth phase, can be determined by the availability of exogenous carbohydrates. Measurements of some of the key enzymes in carbohydrate metabolism show that the enzymes were present in the ungerminated pollen grain, and that the enzyme activity increased severalfold during tube growth. The increase in enzyme activity was prevented if inhibitors of protein synthesis were present in the medium.

Spectroscopic properties of the dwarf nova-type cataclysmic variables observed by LAMOST

Spectra of 76 known dwarf novae from the LAMOST survey were presented. Most of the objects were observed in quiescence, and about 16 systems have typical outburst spectra. 36 of these systems were observed by SDSS, and most of their spectra are similar to the SDSS spectra. Two objects, V367 Peg and V537 Peg, are the first spectra of the object. The spectrum of V367 Peg shows a contribution from an M-type donor and its spectral type could be estimated as M3-5 by combining its orbital period. The signature of a white dwarf spectrum can be seen clearly in four low-accretion-rate WZ Sge stars. Other special spectral features worthy of further observations are also noted and discussed. We present a LAMOST spectral atlas of outbursting dwarf novae. Six objects have their first outburst spectra given here, and the others were also compared with the published outburst spectra. We argue that these data will be useful for further investigation of the accretion disc properties. The He ii λ4686 emission line can be found in the outburst spectra of seven dwarf novae. These objects are excellent candidates for probing the spiral asymmetries of accretion disc.
Sporadic cubic torsion

Let $K$ be a number field, and let $E/K$ be an elliptic curve over $K$. The Mordell--Weil theorem asserts that the $K$-rational points $E(K)$ of $E$ form a finitely generated abelian group. In this work, we complete the classification of the finite groups which appear as the torsion subgroup of $E(K)$ for $K$ a cubic number field. To do so, we determine the cubic points on the modular curves $X_1(N)$ for \[N = 21, 22, 24, 25, 26, 28, 30, 32, 33, 35, 36, 39, 45, 65, 121. \] As part of our analysis, we determine the complete list of $N$ for which $J_0(N)$ (resp., $J_1(N)$, resp. , $J_1(2,2N)$) has rank 0. We also provide evidence to a generalized version of a conjecture of Conrad, Edixhoven, and Stein by proving that the torsion on $J_1(N)(\mathbb{Q})$ is generated by $\text{Gal}(\bar{\mathbb{Q}}/\mathbb{Q})$-orbits of cusps of $X_1(N)_{\bar{\mathbb{Q}}}$ for $N\leq 55$, $N \neq 54$.
Evaluation of oxytetracycline in the prevention of American foulbrood in bee colonies

In this paper we presented the procedure of artificial infection of bee colonies with American Foulbrood by the spores of Panibacillus larvae (P. larvae). Bee colonies were treated with oxytetracycline that was applied in a patty and sugar syrup. The symptoms and the course of the disease within the bee colony were monitored. Our research included 20 bee colonies divided in three experimental and one control group. Every bee colony consisted of 2000 young worker bees and a young breeder queen. After laying of first eggs three experimental groups were infected with spore-suspension of P. larvae at concentration 2x109 spore/ml. The development of the disease was monitored under the following experimental conditions: Experimental group I did not receive antimicrobial therapy, Groups II and III were given antibiotics in a sugar syrup and extender patty, respectively. In the first experimental group the first clinical signs were observed on day 25. while vegetative form of P. larvae was detected on day 12. Treatment with oxytetracycline in the second and third group delayed the manifest disease until day 47. Key words: Bee colonies, American foulbrood, oxytetracycline.
Insider Trading with Temporary Price Impact

We model an informed agent with information about the future value of an asset trying to maximize profits when the agent’s trades are subjected to a transaction cost as well as a market maker tasked with setting fair transaction prices. In a single auction model, equilibrium is characterized by the unique root of a particular polynomial. Analysis of this polynomial with small levels of risk-aversion and transaction costs reveal a dimensionless parameter which captures several orders of asymptotic accuracy of the equilibrium behavior. In a continuous time analogue of the single auction model, incorporation of a transaction costs allows the informed agent’s optimal trading strategy to be obtained in feedback form. Linear equilibrium is characterized by the unique solution to a system of two ordinary differential equations, of which one is forward in time and one is backward. When transaction costs are in effect, the price set by the market maker in equilibrium is not fully revealing of the informed agent’s private signal, leaving an information gap at the end of the trading interval. When considering vanishing transaction costs, the equilibrium trading strategy and pricing rules converge to their frictionless counterparts.
DISPERSAL BEHAVIOR OF ADULT AEDES STICTICUS AND AEDES VEXANS (DIPTERA: CULICIDAE) IN MANITOBA

Abstract In 1976 and 1977, adults of Aedes sticticus (Meigen) and Aedes vexans (Meigen), marked with fluorescent dust, were captured in light traps up to 33 days after release and at distances up to 11 km from the release site. Adults flew primarily northwest from the release sites, and with the prevailing winds. Porcine and bovine hosts present at some of the trapping sites, appeared to be highly attractive to female mosquitoes. Within an 8 km trapping radius of the release site, the mean number of marked/trapped female mosquitoes decreased with distance. In 1977, 50% of the marked captures (weighted according to km2 of trapping area) were taken within the first 2 km, 82% within 4 km, 92% within 6 km, and the remainder out to 8 km from the release site. For all trap sites, the mean recovery of marked/unmarked adults over a 33 day trapping period in 1977 was 1:1113.
Characterisation and comparison of phenols, flavonoids and isoflavones of soymilk and their correlations with antioxidant activity

Summary To investigate the relationship between bioactive compounds and antioxidant property, total phenolic content (TPC), total flavonoid content (TFC), individual and total isoflavone content of soymilk and their correlations with oxygen-radical-absorbing capacity (ORAC), ferric reducing antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity values were evaluated and compared. Results showed that TPC, TFC, isoflavones (including concentration and profiles) and antioxidation activity significantly varied among ten tested soybean cultivars. Significant correlations were established between DPPH and TFC (r = 0.553, P < 0.01), DPPH and TPC (r = 0.753, P < 0.01), FRAP and TFC (r = 0.599, P < 0.01) and FRAP and TPC (r = 0.616, P < 0.01). Positive linear correlations were found between subtotal, total isoflavones and ORAC. Unlike other isoflavone monomers, aglycone isoflavones correlated positively with DPPH and FRAP significantly. DPPH well correlated with FRAP, whereas neither DPPH nor FRAP correlated with ORAC. TPC, TFC, individual and total isoflavone values are potentially useful for soymilk antioxidant activity assessment.
Therapeutic evaluation of Acacia nilotica (Linn) stem bark extract in experimental African trypanosomiasis

Summary: Chemotherapy of African trypanosomiasis still remains far from being satisfactory, being severely limited by a number of factors including unacceptable toxicity, increasing parasite resistance, high cost and unavailability. There is an urgent need for therapeutic agents that are effective, affordable and accessible to the rural poor in Africa who bear most of the disease burden. The objective of this study was to evaluate the therapeutic effects of Acacia nilotica in experimental Trypanosoma brucei brucei infection in mice. Methanol extract of stem bark of the plant was investigated for its therapeutic effects in experimental African trypanosomiasis. Acute toxicity studies were also conducted. Crude extract of 70% v/v (Methanol/Water) at a dose of 400mg kg -1 body weight per day completely cured the experimental T.b. brucei infection in mice, while doses of 50, 100, 200, 300, and 400mgkg -1 body weight per day of the partially purified extract completely cured the experimental infection in mice within two days. Sub inoculation of blood and cerebrospinal fluid drawn from the cured mice into healthy mice failed to produce any infection within 28 days of post inoculation. Phytochemical analysis showed the presence of carbohydrates, saponin, tannin and cardiac glycoside. LD 50 of the partially purified extract was found to be 2000mg/kg body weight, the extract being acutely toxic at a dose of 1600mgkg -1 body weight. It is concluded that methanol extract of stem bark of A. nilotica cures experimental T. b. brucei infection in mice. Industrial relevance: The findings in this study provide very useful clue for biopharmaceutical industries and drug manufacturers for the development of phytotherapeutic agents from this plant, not only for therapeutic intervention in the control of African trypanosomiasis but also for the treatment of cancer. This is because of the strong link between Chemotherapy of human African trypanosomiasis (sleeping sickness) and cancer chemotherapy as every drug currently used for the treatment of sleeping sickness has some form of anticancer activity. Moreover, the plant is used in folk medicine for the treatment of cancer. The potential is also very high for the manufacture of highly efficacious drugs for the treatment of sleeping sickness and/or cancer through synthetic modification of isolated bioactive phytoconstituents from this plant. The possibility also exists for the development of anti-diabetic drugs from extracts of this plant.
Histological Analysis of Female Redbelly Tilapia; Tilapia zillii (Gervais, 1848) Ovary, Fed Bitter Melon, Momordica charantia (Cucurbitaceae) Leaf Meal

This research was carried out to control tilapia population using M omordica charantia leaf meal as reproduction inhibitors. A total of 150 post juvenile Tilapia zillii female fish, weighing 30.36 ± 0.13 g were used. The leaf of Mormodica charantia (Bitter melon) was added to a basal diet (35% crude protein) at 0, 20, 40, 60 and 80 g/kg diets and fed to female Tilapia zillii for 80 days. The fish were distributed in triplicate into 15 plastic tanks (1×1×1 m) at a stocking density of 10 fish per tank. Borehole water with pH value between the range of 6.90-7.67, temperature range between 25.4-26.6 o C and dissolved oxygen; 2.8-3.9 ml/l were used. The water volume of 400litres was maintained throughout the period of experiment. The fish was fed at 4% body weight/day in two installments at 09:00-09:30 hs. Histological examination of ovary in T. zillii fed 0 g of MCLM/kg diet showed no visible lesions nuclei of follicle cells were prominently seen while in treatment containing 20 g of MCLM/kg, few oocytes was seen in the ovary and there was generalized congestion, 40 g MCLM/kg diet section showed necrosis of the ovary, few oocytes were found in the ovary. In fish fed 60 g MCLM/kg diet, necrosis and abnormal gonadal development was noticed and ovary was devoid of oocytes. In fish fed 80 g MCLM, highly abnormal gonadal development and necrosis was noticed. Phyto chemical analysis of Momordica charantia showed the presence of charantin, alkaloids, momordicins, tannin, steroid, saponin, terpeniod and glycosine. There was decrease in fecundity (from 286 to 100), relative fecundity (from 3.91 to 1.24), and gonadosomatic index with increase in level of treatments used. Histological observations and fecundity analysis of T. zillii fed high dietary MCLM diet levels revealed that Bitter melon leaves may be effective as sterility-inducing agents in T. zillii .
Coupled Convolutional Neural Network With Adaptive Response Function Learning for Unsupervised Hyperspectral Super Resolution

Due to the limitations of hyperspectral imaging systems, hyperspectral imagery (HSI) often suffers from poor spatial resolution, thus hampering many applications of the imagery. Hyperspectral super resolution refers to fusing HSI and MSI to generate an image with both high spatial and high spectral resolutions. Recently, several new methods have been proposed to solve this fusion problem, and most of these methods assume that the prior information of the point spread function (PSF) and spectral response function (SRF) are known. However, in practice, this information is often limited or unavailable. In this work, an unsupervised deep learning-based fusion method—HyCoNet—that can solve the problems in HSI–MSI fusion without the prior PSF and SRF information is proposed. HyCoNet consists of three coupled autoencoder nets in which the HSI and MSI are unmixed into endmembers and abundances based on the linear unmixing model. Two special convolutional layers are designed to act as a bridge that coordinates with the three autoencoder nets, and the PSF and SRF parameters are learned adaptively in the two convolution layers during the training process. Furthermore, driven by the joint loss function, the proposed method is straightforward and easily implemented in an end-to-end training manner. The experiments performed in the study demonstrate that the proposed method performs well and produces robust results for different data sets and arbitrary PSFs and SRFs.
