Fish Parasites in Zarivar Lake

Twenty four ecto- and endo- parasite species were found in different organs of eight native and exotic fish species in Zarivar Lake situated in the far west of Iran. Overall, 1000 fish specimens belonging to the Dactylogyridae, Gyrodactylidae families the Cyprinidae, Poeciliidae and Mastacembelidae families were examined during 2001 and 2002. Of them, five Protozoans, including Trichodina pediculus, Trichodina sp and Myxobolus molnari, a pansporogenic stage of the Myxosporean plasmodia and Ichthyophthirius multifiliis were recorded. Of the Metazoan parasites, 12 monogenean species, mostly belonging to the Dactylogyridae, Gyrodactylidae families and the Ancyrocephalinae subfamily, were found and identified at species and genus level. The number of helminthes reached 15 by adding one Digenea metacercaria (Diplostomum spathaceum) and 2 coelozoic Cestoda species. Crustacean species found on both of native and exotic fishes, belonging to Copepoda and Branchiora orders comprised of Argulus foliaceus and Lernaea cyprinacea, in addition an unknown Argulus was also found on skin and gills of spiny eel which identified to genus level. The only nematode found in the intestine of common carp was identified as Pseudocapillaria tomentosa. Besides the first record of parasites of spiny eel, the seasonal prevalence of ligulosis is presented. Additionally, zoogeographical analysis and species composition of parasitic fauna of Zarivar Lake are discussed.
The Relationship between Employee Engagement, HRM Practices and Perceived Organizational Support: Evidence from Banking Employees

The purpose of this study is to investigate the relationship between HRM practices and employee engagement. Although employee engagement has got a great attention among the industry practitioners in recent times, it requires more considerations particularly in the academic literature. Based on the norms of social exchange theory (SET), this study has developed the framework to examine the role of perceived organizational support (POS) on HRM practices-employee engagement linkage. Survey data has been collected from employees who are working in different private commercial banks in Bangladesh. This study has used a sample of 376 employees using cluster sampling technique. To analyze the data, this study has employed SmartPLS 3.0 version software. The results of structural equation modeling revealed that HRM practices namely career advancement, job security and performance were significantly and positively related to employee engagement. The results also showed that POS can moderate the relationship between HRM practices and employee engagement. It suggests that in the presence of POS, relatively low level of employees’ perceptions regarding job related resources will exert a high level of employees’ behavioral outcomes such as engagement. The implications and suggestions for future research have also been discussed.
ElectromagneticLevitation Part I: Theoretical and Experimental Considerations

Levitation of liquid bodies against gravity is a contactless confinement process ap- propriate for manufacturing very pure materials. A variety of levitation techniques have been de- veloped over the last few decades, such as aero- dynamic, acoustic, electrostatic, microwave, and electromagnetic levitations. More recently, a new generation of novel techniques, essentially combinations of the established primary tech- niques, has been successfully introduced. Exam- ples are acoustic-electric, aerodynamic-acoustic and acoustic-electromagnetic. Thepurposeofthis series of papers in three parts, Bakhtiyarov and Siginer (2007a,b), is to review the advances in electromagnetic levitation (EML) since its intro- duction as a containerless melting technique, and a tool for the determination of the thermophysical properties of molten metals under both terrestrial and microgravity conditions.

Pyrethrum debeauxii, a poorly-known annual species endemic to SE-Spain, was studied in detail and compared with related genera. It is found to represent a new monotypic genus, Castrilanthemum Vogt & Oberprieler. The new combination C. debeauxii (Degen, Hervier & E. Rev.) Vogt & Oberprieler is proposed.
Abiotic Oxidation Rate of Chalcopyrite: Implications for Seafloor Mining

In situ mining of seafloor massive sulfide (SMS) deposits will have consequences thus far not quantified. On land, interaction of mined sulfide minerals with surface and groundwaters yields acid mine drainage. Pulverization of SMS on the ocean floors will produce highly reactive sulfide mineral surface areas, leading to the localized potential for seafloor acid generation. Chalcopyrite (CuFeS2) is one of several ore minerals found in SMS deposits whose oxidation kinetics need to be quantified to estimate the significance of acid production. To constrain the oxidation rate of chalcopyrite in seawater, the initial rate experimental method was employed and combined with the isolation method to derive a rate law. Data collected from batch reactor experiments without abundant precipitates (pH -9.38 (PO2) 1.22 (H+) 0.36 Chalcopyrite oxidizes slowly in seawater relative to other sulfide minerals like pyrrhotite (Fe1-xS), so data from this study establishes a minimum rate of abiotic SMS weathering by oxidation. The slow rate of oxidation of chalcopyrite observed here has positive implications for seafloor mining. Not only will this sulfide not be the main culprit for acid production, but the copper ore will arrive at the surface with minimal dissolution and loss of metal value. Constraining the oxidation rates of individual sulfide mineral species will be useful in modeling SMS mining repercussions, as well as quantifying rates of natural chemical weathering in the oceans over geologic time. This information will be applicable to interpreting the Cu/Fe ratios of VMS deposits.The potential for local acid generation can be viewed as a microcosm of the global problem of ocean acidification caused by dissolution of anthropogenic atmospheric CO2. Data show sulfide mineral oxidation rates increase with lower pH, implying that a worldwide drop in ocean pH may amplify the dissolution of SMS deposits, changing the marine ecosystem.
Framed curves in the Euclidean space

Abstract A framed curve in the Euclidean space is a curve with a moving frame. It is a generalization not only of regular curves with linear independent condition, but also of Legendre curves in the unit tangent bundle. We define smooth functions for a framed curve, called the curvature of the framed curve, similarly to the curvature of a regular curve and of a Legendre curve. Framed curves may have singularities. The curvature of the framed curve is quite useful to analyse the framed curves and their singularities. In fact, we give the existence and the uniqueness for the framed curves by using their curvature. As applications, we consider a contact between framed curves, and give a relationship between projections of framed space curves and Legendre curves.
PRODUCTIVITY AND HISTORY AS PREDICTORS OF THE LATITUDINAL DIVERSITY GRADIENT OF TERRESTRIAL BIRDS

The latitudinal diversity gradient is the largest scale, and longest known, pattern in ecology. We examined the applicability of three versions of the energy hypothesis, the habitat heterogeneity hypothesis, and historical contingency to the gradient of terrestrial birds. The productivity version of the energy hypothesis, tested using actual evapotrans- piration, a water-energy variable closely associated with plant productivity, accounted for 72% of the variance in a model of global extent. An historical contingency model based on biogeographic region explained 58% of the variance. A combined climate-region model accounted for 78% of the variance, but 52% comprised the overlap between these effects. This suggests that further resolution of contemporary vs. historical processes at the global level will require the inclusion of phylogenetic information. Regional-extent regression models suggest a latitudinal shift in constraints on diversity; measures of ambient energy (potential evapotranspiration and mean annual temperature) best predicted the diversity gradient at high latitudes, whereas water-related variables (actual evapotranspiration and annual rainfall) best predicted richness in low-latitude, high-energy regions. Intraregional spatial autocorrelation analysis confirmed that climatic models ad- equately describe geographic richness patterns at all but the smallest spatial scales resolved by the analysis. We conclude that the ''water-energy dynamics'' hypothesis, originally developed for plant diversity gradients, offers a parsimonious explanation for bird diversity patterns as well, presumably operating via plant productivity. However, more refined tests of historical factors are needed to fully resolve their influences on the gradient.
Post-Transcriptional and Translational Mechanisms of Regulation of Gene Expression in T Cell Subsets

The immune system is under strict regulatory control to ensure homeostasis of inflammatory responses, lying dormant when not needed but quick to act when called upon. Small changes in gene expression can lead to drastic changes in lineage commitment, cellular function, and immunity. Conventional assessment of these changes centered on the analysis of mRNA levels through a variety of methodologies, including microarrays. However, mRNA synthesis does not always correlate directly to protein synthesis and downstream functional activity. Work conducted in recent years has begun to shed light on the various post-transcriptional changes that occur in response to a dynamic external environment in which a given immune cell type encounters. In this chapter, we provide a critical review of key post-transcriptional and translational mechanisms of regulation of gene expression in the immune system, with an emphasis of these regulatory processes in various CD4+ T cell subsets and their related effector functions.
The Social Value of Persons: Theory and Applications

When people talk about an object in their environment, they have recourse not to scientific language, but to evaluative language. This evaluative language allows them to say what one does, can do or must do with that object (i.e., its functional or social value). For instance, when Mrs Smith talks about an orchid that someone has given her, she says, It's so delicate and refined! Its flowers come in fantastic shapes and yet it’s really easy to grow. When she talks about the meat she is cooking for dinner, she says, It's tender, juicy, and smells good. Statements like these make sense, but not scientific sense. These words are not the words of a botanist or a physiologist. This is a language used to say what one does, can do or must do with a flower or a cut of meat, something that is never expressed in descriptive or scientific language. A botanist might say, for example, that an orchid has three colorful sepals and three petals, that two of the petals are underdeveloped, that the third, on the contrary, is highly developed and forms the labellum, and so on. A physiologist might say that muscle is made up of thousands of cylindrical cells called muscle fibers, that each fiber is enveloped and separated from the others by a thin layer of connective tissue the endomysium -, and so on. Curiously, though, when Mrs Smith talks about her friends or neighbors, many social psychologists opine that the words she uses to describe those friends and neighbors are more like the descriptive or scientific words of the botanist or physiologist than the evaluative words she uses to talk about meat or flowers.
Organic and inorganic fertilizers influence biomass production and esculin content in Cichorium intybus

Cichorium intybus L. is a promising and potent industrial medicinal herb but the relatively low content of esculin and unavailability of mass scale propagation protocol are major impediments for the commercial production of the drug. The enhancement in the yield of esculin is hence, highly desirable, which can be achieved by adequate and judicious supply of plants nutrients or by adopting more expensive and complex protocol of biotechnology. The field experiment was designed in random plots to study the effect of organic manure (20 tonnes ha-1) and chemical fertilizers (N240, P120, K100, S80, kg ha−1; Nitrogen, Phosphorus, Potassium and Sulphur, respectively) on the accumulation of esculin and biomass in various plant parts through the various developmental stages, rosette, bolting, pre-flowering, flowering and post-flowering of C. intybus. Esculin yield from dried leaves increased significantly at flowering stage in the plants treated with N80+100+60 + P120 + K100 + S 20+40+20 (31.71% and 111.22 %) when compared with control. Yield of dry leaf biomass ranged between 628.15 to 986.07 kg ha−1 at flowering stage in various treatments.
Observed Temperature Effects on Hourly Residential Electric Load Reduction in Response to an Experimental Critical Peak Pricing Tariff

The goal of this investigation was to characterize the manual and automated response of residential customers to high-price critical events dispatched under critical peak pricing tariffs tested in the 2003-2004 California Statewide Pricing Pilot. The 15-month experimental tariff gave customers a discounted two-price time-of-use rate on 430 days in exchange for 27 critical days, during which the peak period price (2 p.m. to 7 p.m.) was increased to about three times the normal time-of-use peak price. We calculated response by five-degree temperature bins as the difference between peak usage on normal and critical weekdays. Results indicated that manual response to critical periods reached -0.23 kW per home (-13 percent) in hot weather (95-104.9oF), -0.03 kW per home (-4 percent) in mild weather (60-94.9oF), and -0.07 kW per home (-9 percent) during cold weather (50-59.9oF). Separately, we analyzed response enhanced by programmable communicating thermostats in high-use homes with air-conditioning. Between 90oF and 94.9oF, the response of this group reached -0.56 kW per home (-25 percent) for five-hour critical periods and -0.89 kW/home (-41 percent) for two-hour critical periods.
Calibration and evaluation of CCD spectroradiometers for ground-based and airborne measurements of spectral actinic flux densities

The properties and performance of charge-coupled device (CCD) array spectroradiometers for the measurement of atmospheric spectral actinic flux densities (280–650 nm) and photolysis frequencies were investigated. These instruments are widely used in atmospheric research and are suitable for aircraft applications because of high time resolutions and high sensitivities in the UV range. The laboratory characterization included instrument-specific properties like the wavelength accuracy, dark signal, dark noise and signal-to-noise ratio (SNR). Spectral sensitivities were derived from measurements with spectral irradiance standards. The calibration procedure is described in detail, and a straightforward method to minimize the influence of stray light on spectral sensitivities is introduced. From instrument dark noise, minimum detection limits ≈ 1 × 10 10 cm −2 s −1 nm −1 were derived for spectral actinic flux densities at wavelengths around 300 nm (1 s integration time). As a prerequisite for the determination of stray light under field conditions, atmospheric cutoff wavelengths were defined using radiative transfer calculations as a function of the solar zenith angle (SZA) and total ozone column (TOC). The recommended analysis of field data relies on these cutoff wavelengths and is also described in detail taking data from a research flight on HALO (High Altitude and Long Range Research Aircraft) as an example. An evaluation of field data was performed by ground-based comparisons with a double-monochromator-based, highly sensitive reference spectroradiometer. Spectral actinic flux densities were compared as well as photolysis frequencies j (NO 2 ) and j (O 1 D), representing UV-A and UV-B ranges, respectively. The spectra expectedly revealed increased daytime levels of stray-light-induced signals and noise below atmospheric cutoff wavelengths. The influence of instrument noise and stray-light-induced noise was found to be insignificant for j (NO 2 ) and rather limited for j (O 1 D), resulting in estimated detection limits of 5 × 10 −7 and 1 × 10 −7 s −1 , respectively, derived from nighttime measurements on the ground (0.3 s integration time, 10 s averages). For j (O 1 D) the detection limit could be further reduced by setting spectral actinic flux densities to zero below atmospheric cutoff wavelengths. The accuracies of photolysis frequencies were determined from linear regressions with data from the double-monochromator reference instrument. The agreement was typically within ±5 %. Because optical-receiver aspects are not specific for the CCD spectroradiometers, they were widely excluded in this work and will be treated in a separate paper, in particular with regard to airborne applications.
Daidzein Modulations of Apolipoprotein B and Fatty Acid Synthase mRNA Expression in Chick Liver Vary Depending on Dietary Protein Levels

This study was designed to determine the effects of daidzein (DE) on hepatic lipid metabolism in chicks fed with low protein (LP) diet based on casein. In experiment 1, the male chicks were fed with one of the three levels of dietary protein containing 10.95%, 21.9% and 43.8% protein content for 2 days. In experiment 2, the chicks were fed one of the three levels of protein with or without DE at 1,000 mg/kg diet for 2 days. Experiment 3 was conducted to compare DE (LP+DE) with estradiol (LP+E2) in chicks fed with LP diet for 7 days. Plasma lipid profiles, hepatic lipid profiles, activities of hepatic malic enzyme and isocitrate dehydrogenase (ICDH) were measured. Transcriptions of hepatic fatty acid synthase, apolipoprotein-B (APO-B), and fructose bisphosphatase mRNA were measured by RT-PCR. Increasing dietary protein levels markedly decreased the concentrations of plasma triglycerides, hepatic total lipids, hepatic TG, and the mRNA transcriptions while the increased dietary protein levels increased hepatic ICDH activities in experiment 1. In experiment 2, the effects of dietary protein levels on blood and hepatic lipid content were more prominent than those of the additional DE. Interestingly, plasma TG levels were affected by DE supplementation (p<0.05). In experiment 3, DE inhibited APO-B mRNA expressions and stimulated the accumulation of lipid in the liver through mechanisms different from E2. In this study, we demonstrate that DE has beneficial effects on blood lipid profiles, but that it inhibits APO-B mRNA transcription and aggravates the fatty liver induced by LP diet in chicks.

Effects of organic matter application on methane emission from paddy fields adopting organic farming system

A study that was aimed to determine the effect of the use of organic manure and azolla on methane emission on paddy field of organic systems was conducted on paddy fields in the Gempol Village, Sambirejo District of Sragen Regency, Indonesia. The experimental design performed for this study was a completely randomized block design consisting of three factors; the factor I was rice cultivars (Mira-1; Mentik Wangi; Merah Putih); factor II was dose of organic manure (0 t/ha and 10 t/ha) and factor III was Azolla inoculums dose (0 t/ha and 2 t/ha). Gas sampling was conducted 3 times in one growing season when the rice plants reached ages of 38, 66 and 90 days after planting. The results showed that there was no correlation between the uses of organic fertilizers for rice production on methane emission. The increase of methane emission was very much influenced by the redox potential. Methane emission from Mira-1 field was higher than that from Mentik Wangi and Merah Putih fields. Emission of methane gas from Mira-1 field ranged from -509.82 to 791.34 kg CH 4 /ha; that from Wangi ranged from -756.77 to d 547.50 kg CH 4 /ha and that from Merah Putih ranged from -399.63 to 459.94 kg CH 4 /ha. Application of 10 t organic manure /ha and 2 t azolla/ha in Mentik Wangi reduced methane emissions with a high rice production compared to Merah Putih and Mira-1.

HOW DOES BOND MARKET VIEW IT INVESTMENTS

This study investigates the business value of information technology (IT) in terms of performance in bond markets, which constitute the single largest source for firms’ financing. We evaluate risk-adjusted benefits of IT investments in the bond market in the United States over the 1995-2002 period. We find a significant association between a firm’s IT intensity and bond ratings at issuance. The results also indicate that the impact of IT on the cost of debt is different across industries. IT investments have a favorable influence on the cost of debt in automate and informate industries but not in transform industries. This finding from the bond markets differs from that in prior equity market findings which report higher returns to IT investments in transform industries. These findings suggest that bondholders and shareholders have different perspectives toward IT investments.
Corporate Real Estate Holdings: Fool's Gold or Crown Jewel?

This paper aims to introduce new evidence of consistently negative impacts on enterprise value when corporations increase real estate holdings. Adopting a different approach from previous studies, our data analysis shows that corporate real estate portfolios and enterprise value share an inverse relationship. Surprisingly, this trend was seen during the Japanese real estate bubble in the late 1980' s. Previous reports from the United States and Singapore show that only in the retail sector do increases in corporate real estate holdings have a positive influence on stock performance. However, our research indicates that the stock performance of Japanese firms in the retail sector was negative across the board for firms in other sectors.
