Honey bee colony population in relation to brood rearing and stored pollen

The present work was carried out to study the relationship between brood rearing activity, bee density and stored pollen grains. Fifteen colonies, 1st. Carniolan hybrid nearly in equal strength were put under investigation from June 1994 to May 1995. The results revealed that the major peak of brood activity and higher rate of stored pollen were in May, consequently the maximum number of house bees was recorded during June and July. However no correlation existed, the lowest production of brood, bees and gathered pollen occurred during February. It was found that high significant differences were in quantity of brood and house bees, while low significant differences were in quantity of stored pollen. Correlations between brood activity, house bees density and stored pollen were observed in winter.

DETECTION OF ACINETOBACTER SPECIES IN MILK AND SOME DAIRY PRODUCTS

Two hundred and forty random samples of milk and some dairy products; Domiati, Kareish cheese and cream were collected from Assiut city, Egypt. The collected samples were examined for the incidence of Acinetobacter species using Leeds Acinetobacter selective medium. The obtained results revealed that Acinetobacter species was isolated from 15% of the raw milk samples, 3.3% of the Domiati cheese samples, 13.3% of the Kareish cheese samples and 13.3% of the cream samples, while couldn’t be detected in the pasteurized milk samples. The isolated species were Acinetobacter baumannii, Acinetobacter haemolyticus, Acinetobacter calcoaceticus and Acinetobacter junii. Acinetobacter baumannii was detected using blaOXA-23-like, blaOXA-51-like, and class 1 integrase genes. The characterization of the Acinetobacter species for the production of lipolytic enzyme was studied. Out of the 27 isolated Acinetobacter species, 23 possessed lipolytic activity. The public health hazard of this microorganism in milk and some dairy products was discussed.
Geomorphic Influences on the Distribution of Yellowstone Cutthroat Trout in the Absaroka Mountains, Wyoming

Abstract Influences of large-scale abiotic, geomorphic characteristics on distributions of Yellowstone cutthroat trout Oncorhynchus clarki bouvieri are poorly understood. We sampled 151 sites on 56 perennial streams in the Greybull–Wood river drainage in northwestern Wyoming to determine the effects of geomorphic variables on Yellowstone cutthroat trout distributions. Channel slope, elevation, stream size, and barriers to upstream movement significantly influenced the presence and absence of Yellowstone cutthroat trout. Wild populations of Yellowstone cutthroat trout were not found upstream of barriers to fish migration, at sites with channel slopes of 10% or greater, or at elevations above 3,182 m. Based on channel slope alone, logistic regression models correctly classified presence or absence of Yellowstone cutthroat trout in 83% of study sites. The addition of elevation and stream size in the models increased classification to 87%. Logistic models tested on an independent data set had agreement rates .
Cytotoxicity of surfactants to the FHM-sp cell line

: Cytotoxicity of eight surfactants was determined by the neutral red assay with the fathead minnow (FHM)-sp cell line, a cell line in suspension culture from fish. The toxicity ranking of the surfactants was benzalkonium chloride > benzethonium chloride > sodium linear-dodecylbenzene–sulfonate (LAS) > potassium laurate > sodium dodecylsulfate > polyoxyethylene(20)sorbitan monolaurate > polyoxyethylene(20)sorbitan monooleate > betaine. The toxicity ranking of the surfactants classified into four groups based on the ion of the hydrophilic group was cationic surfactants > anionic surfactants > non-ionic surfactants > amphipathic surfactants. The FHM-sp cells, as well as the chinook salmon embryo (CHSE)-sp cells, could be inoculated directly to the microplate wells without dispersion by trypsin treatment of cell sheets at room temperature. Therefore, the cytotoxicity assay of the surfactants could be carried out quickly by using the FHM-sp cell line. The FHM-sp cell line had similar or higher sensitivity to sodium dodecylsulfate compared with several cell lines from mammals. The cytotoxicity assay could be shortened by the procedure exposing the surfactants to the FHM-sp cells before the cell monolayer formation in the microplate wells. To use the FHM-sp cell line as a screening tool prior to in vivo testing, studies on the correlation between in vivo data and in vitro data on the toxicity of surfactants are necessary.
Effect of Dietary Oat and Wheat Bran on Biochemical Changes in Rats Fed High Fat- High Cholesterol Diets

The purpose of this study aims to examine the efficiency of using either oat or wheat bran (5 or 10%) on the prevention of hyperlipidemia, hypercholesterolemia induced in rats fed with High Fat-High Cholesterol (HFHC) diets. Sixty adult male albino rats were divided into six groups: (G1) normal control rats fed with balanced diet and (G2) rats fed with hyperlipidemic-hypercholesterolemic which was supplemented with fat and cholesterol at a dose level of 20g and 1g/100g diet respectively. The other four groups of animals were fed with the same previous (HF-HC) diet supplemented with Oat (G3 & G4), while (G5 & G6) were supplemented with wheat bran at levels of 5 and 10% respectively for six weeks. The present study showed that 20% fat and 1% cholesterol administration cause a significant increase in total lipids, total cholesterol, triacylglycerol as well as Low Density Lipoprotein-Cholesterol (LDL-C), Very Low Density Lipoprotein-Cholesterol (VLDL-C), ratio of Low Density Lipoprotein-Cholesterol/High Density Lipoprotein-Cholesterol (LDL-C/HDL-C) and enzymes activities of Asparate Aminotransferase (AST) and Alanine Aminotransferase (ALT) accompanied with decreasing HDL-C compared to normal group. Cholesterol-enriched diet significantly increased serum malondialdehyde (MAD) and significantly decrease glutathione (GSH) content and erythrocyte superoxide dismutase (SOD) activity as compared with balanced diet group. Rats fed oat or wheat bran at tested doses resulted in a significant decrease in glucose, lipid parameters and a significant improve in antioxidants as well as enzymes activities of AST and ALT compared with those fed HF-HC diet. It was concluded that both Oat and wheat bran at dose 10% had anti-atherogenic hypolipidemic effect and reduced oxidative stress via inhibition of reactive oxygen species and lipid peroxidation as well as increment of antioxidant enzymes.

Adaptive Cluster Sizing for Residual Resource Harvesting in Interactive Clouds

The popularity of cloud-based interactive computing services (e.g., virtual desktops) brings new management challenges: each VM leaves abundant but ﬂuctuating residual resources while being intolerant to latency, potentially caused by aggressive VM consolidation. In this paper, we design and implement RHIC, an autonomous management framework to harness such dynamic residual resources aggressively without slowing the harvested interactive services. RHIC builds a batch cluster using a hybrid of residual and dedicated resources and intelligently discovers and maintains the ideal cluster size and composition, given goals such as cost/energy minimization or deadlines. RHIC employs black-box techniques and requires only system-level metrics to model workload performance. We demonstrate the effectiveness and adaptivity of our RHIC prototype with two parallel data analytics frameworks, Hadoop and HBase. Our results show that RHIC ﬁnds near-ideal cluster sizes/compositions across workloads and goals. Further, it signiﬁcantly outperforms alternative approaches and tolerates high instability in the harvested interactive cloud.
Influence Of Some Fertilizer Treatments On Productivity And Fruit Quality Of Strawberries

Field experiment was carried out at Shebeen El-Kanater region, El-Qulybiya Governorate, Egypt, during 2005/2006 and 2006/2007 seasons, on fresh strawberry plants cv. Camarosa. This work aimed to determine the optimal N and K fertilizer levels and investigate the effect of nitrogen sources on the productivity and fruit quality of strawberries. The experiment was arranged in split-split plot design with three replicates. Three nitrogen levels (100, 80 and 60 kg N/fed.) were arranged in the main plots, three nitrogen sources (100% ammonium sulphate, 100% poultry manure and 50% poultry manure + 50% ammonium sulphate) were distributed in the sup-plots and two potassium levels (150 and 200 kg K2O/fed.) were assigned in the sub-sub plots. Results showed that increasing nitrogen levels resulted in increasing of vegetative growth parameters (plant length, leaf number and leaf area) and early marketable yield but decreased number of flowers per plant and total marketable yield. Increasing nitrogen levels also increased average fruit weight but decreased fruit firmness and had non-significant effect on T.S. S %. Results also showed that 100% ammonium sulphate (as a nitrogen source) was the remarkable treatment for vegetative growth, fruit yield and quality of strawberries, followed by 50% poultry manure + 50% ammonium sulphate treatment. High potassium level (200 kg K2O/fed.) produced the highest values of vegetative growth, flowering, fruit yield and quality. Concerning the effect of interaction among nitrogen levels, nitrogen sources and potassium levels, the results revealed that application of 60 kg N/fed. of 100% ammonium sulphate and 200 kg K2O/fed. was the best treatment for early, total marketable yield and fruit quality characteristics.
Changes in the water quality of Lake Geneva indicated by submerged macrophytes

SUMMARY 1. The distribution of submerged macrophytes along 20 km of lake shore (Lake Geneva, Switzerland) was compared between the years 1972, 1984 and 1995. Lake Geneva underwent rapid eutrophication until 1980, followed by reversal that is still in progress. Potamogeton pectinatus, P. perfoliatus, P. lucens and Elodea canadensis showed no significant changes in their distribution, with the two former species dominant throughout. Chara sp. , and to a lesser degree Myriophyllum spicatum, decreased in abundance between 1972 and 1984 but had increased again by 1995. The abundance of P. pusillus increased regularly, while Zannichellia palustris and P. crispus almost disappeared from the study area. Elodea nuttallii was observed for the first time in Lake Geneva in 1995. 2. Two methods of bioindication of water quality by macrophytes are compared. The macrophyte index proposed by Melzer (1988) is based on nutrient load, whereas the saprobic index proposed by Sladecek (1973) measures organic pollution. The saprobic index is sensitive to small changes in species composition and abundance, and also reflects better the changes in eutrophication. It may therefore be a better bioindicator. 3. Geographic Information Systems (GIS) are useful for mapping and storing information on submerged vegetation allowing easy interrogation, updating and plotting of spatial information at various scales, and providing a reference for future comparisons.
Does Conservative Accounting Matter to Cash Dividend Policy?

We investigate whether conservative accounting mitigates creditor-stockholder agency problems by protecting the interests of creditors through the firm’s dividend policy. By investigating data on Chinese listed firms from 2001 to 2006, we have found that though the relation between cash dividend policy and conservative accounting in China is inconsistent with that in the U.S, the role of conservative accounting in cash dividend is the same that the use of conservative accounting reduces the probability of paying cash dividends and the amount of cash dividend payout. In this way, conservative accounting helps to protect the interests of creditors and to mitigate the credit-stockholder agency conflict. We have also found that the negative relationship between accounting conservatism and dividend policy for state-owned enterprises (SOEs) is weaker and smaller than for non-state-owned enterprises (NSOEs). Finally, we conclude that the relationship between accounting conservatism and dividend payments is induced by the stockholder-creditor agency relationship instead of non-creditor reasons: conservative accounting does not have a statistically significant impact on the dividends of firms with low debt. *Corresponding author
Investigation of the Role of Selected Fungal Strains in the Removal of Phosphate and Nitrate in Synthetic Wastewater

Aims: This study investigate the role of four fungi species in the removal of phosphate and nitrate in a low nutrient synthetic wastewater. Also investigated was the effect of initial inoculum size on the nutrient removal ability of the strains. Materials and Methods: The fungal strains used for the study were Aspergillus niger, Aspergillus flavus, Absidia spp and Fusarium spp Four different initial inoculum sizes of each of the respective isolates were used for the nutrient removal studies. After inoculation with the test strains, aliquot samples were taken from the media at time zero and every 24h, for the estimation of total phosphate, nitrate and pH in the medium, using standard methods. Results: All the strains showed nitrate removal ability, irrespective of the initial inoculum size used for inoculation. After 96 h, the percent nitrate removed ranged from 25.25% to 77.52%, 26.12% to 39.80%, 8.88% to 44.23% and 29.50% to 87.34%, in the presence of Aspergillus niger, Aspergillus flavus, Absidia spp and Fusarium spp, respectively. None of the fungi exhibited phosphate removal ability, except Aspergillus niger which showed very slight potential for phosphate removal. Despite the observed differences in nitrate concentration removed by the different strains, these differences were not observed to differ significantly between the initial inoculum sizes used for investigation (p≤ 0.05). Similarly, the phosphate concentrations in the presence of the test strains did not differ significantly between the different initial inoculum sizes (p≤ 0.05). The pH values of the wastewater inoculated with the fungal strains increased with time of incubation. This trend was also observed irrespective of the initial inoculum size used. Conclusion: The study was able to provide an insight into the phosphate and nitrate removal efficiency of the test strains under the experimental conditions. Keywords: Phosphate; nitrate; fungi; nutrient removal; wastewater.
Action spectrum for melanoma induction in hybrid fish of the genus Xiphophorus

Cutaneous malignant melanoma (CMM) is a complicated disease that is dependent on a number of factors that influence its incidence in ways that are quantitatively uncertain. The incidence of CMM increases with proximity to the Equator -- an observation in line with the conclusion that sun exposure is the most important etiologic agent. However, the latitude effect does not implicate UVB because the intensities of all spectral regions increase toward the Equator. An understanding of the useful public health measures to lower the incidence of CMM would benefit greatly if the spectral region of sunlight implicated in melanoma incidence were known. Such knowledge requires animal models to evaluate the incidence as a function of wavelength. There are marsupial models, a transgenic mouse model, and a fish model. To date, only the fish model has been employed to obtain an action spectrum. The paper describes a fish model, implications of the fish spectrum, and epidemiological data.
Histochemical Localization of Alcohol Dehydrogenase Activities in the Livers of Mice, Rats, Hamsters, and Guinea-Pigs

The hepatic lobular localization of alcohol dehydrogenase (ADH) activity was examined histochemically in mice, rats, hamsters and guinea-pigs with the nitro blue tetrazolium method. In the mouse liver, the ADH activity was localized mainly in the centrilobular zone. In the rat and hamster livers, it was observed throughout the lobule, with increased centrilobular staining. Interestingly, in the guinea-pig liver, it was found to be evenly localized in both the centrilobular and periportal zones, with little or no midlobular staining. These findings show that the distribution pattern of ADH activity in the hepatic lobule of the guinea-pigs differs strikingly from that of the mice, rats and hamsters.
Ferromagnetism of LaCoO3 films

We study ferromagnetic ordering and microscopic inhomogeneity in tensile strained LaCoO3 using numerical simulations. We argue that both phenomena originate from effective superexchange interactions between atoms in the high-spin (HS) state mediated by the intermediate-spin excitations. We derive a model of the HS excitation as a bare atomic state dressed by electron and electron-hole fluctuations on the neighbor atoms. We construct a series of approximations to account for electron correlation effects responsible for HS fluctuations and magnetic exchange. The obtained amplitudes and directional dependence of magnetic couplings between the “dressed” HS states show a qualitative agreement with experimental observations and provide a new physical picture of LaCoO3 films.

Growth and yield of zucchini squash (Cucurbita pepo L.) as influenced by a sunn hemp living mulch

The use of living mulches for managing crop pests has received much attention recently but their effects on primary crop productivity is relatively uninvestigated. This study investigated the influence of a sunn hemp (Crotalaria juncea L.) living mulch on growth, development and yield of zucchini squash (Cucurbita pepo L.). Field experiments were conducted at two locations during three growing seasons. Zucchini squash growth, dry biomass and yield were recorded and compared when inter-planted into a companion sunn hemp living mulch (SH) and grown in monoculture [bare-ground (BG)]. During the first and second study years, when sunn hemp was cut to a height of 45 cm and used concurrently as a living and surface mulch, zucchini plant dry biomass and yield were substantially reduced compared with BG habitats. However, in the third year, when sunn hemp was cut to a shorter height of 20 cm, zucchini plant growth and yield were similar between treatments at one study site and significantly greater in SH than in BG habitat at the other site. Potential causes of yield differences and implications of using sunn hemp as a living companion plant are discussed.
Relative, but not absolute, thinning responses decline with increasing thinning age in a Eucalyptus nitens plantation

Summary Growth rates of trees and stand structure change as stands age, and therefore absolute and relative thinning responses may also vary with thinning age. The study examined whether thinning age influenced the relative and absolute thinning responses in Eucalyptus nitens plantations near Carrajung, Victoria, Australia, and whether this effect was influenced by nitrogen (N) fertiliser application. Two levels of thinning and fertiliser application were applied in a factorial design replicated three times in a randomised block layout in each of two trials established in September 2006 in adjacent plantations aged 3.2 y and 13.2 y respectively and from the same seed source. Treatments included: unthinned or thinned non-commercially from below to 300 trees ha–1; fertiliser treatments were nil or 300 kg ha–1 N as urea in the younger trial and nil or mixed fertiliser supplying 256 kg ha–1 N, 80 kg ha–1 P and 100 kg ha–1 K in the older trial. Five years after thinning, basal areas of the largest 200 sawlog crop trees ha–1 (SCTs) were about 4.1 m2 ha–1 greater in thinned than in unthinned stands, regardless of thinning age, and volumes of SCTs were 30.1 m3 ha–1 greater in thinned stands. As a result of the greater standing basal area and volumes in the older trial, relative thinning responses of SCTs were greater in the younger trial, such that thinning increased the basal area of the SCT200 by about 42% (and volume by 32%) in the younger trial, but by only 21% (and volume by 17%) in the older trial. Fertiliser application also increased absolute thinning responses. Smaller relative thinning responses in the older stand were associated with age-related changes in stand structure of unthinned stands, including increasing skewness and decreasing kurtosis of diameter distributions as stands aged. The absence of a thinning-age effect on absolute responses suggests that there is some flexibility in the thinning age in E. nitens plantations. However, it is important to note that while the absolute thinning response may be slow to decline, the size of the SCTs will be smaller after later-age thinning owing to the extended period of competition they experience prior to thinning.
Do Contrastingly Colored Unripe Fruits of the Neotropical Tree Ardisia nigropunctata Attract Avian Seed Dispersers?

Visual cues in fruit displays from foliage, accessory structures, and ripe fruit color are known to be important in attracting bird seed dispersers to ripe fruit, but the role of color in unripe fruit has not been thoroughly studied. Here, we tested the effects of unripe fruit presence and fruit abundance by offering fruit of a Neotropical tree, Ardisia nigropunctata (Myrsinaceae), in bunches of mixed unripe and ripe fruit and bunches of all‐ripe fruit. Additionally, foraging bird species identification and behavior information was collected. Contrary to expectation, birds removed more fruit from all‐ripe bunches with the most fruit than from contrastingly colored fruit bunches. We therefore discuss alternate explanations for unripe fruit colors in mixed bunches.
