Bisphenol A and the related alkylphenol contaminants in crustaceans and their potential bioeffects

Bisphenol A is widely used in plastic and other industrial consumer products. Release of bisphenol A and its analogues into the aquatic environment during manufacture, use and disposal has been a great scientific and public concern due to their toxicity and endocrine disrupting effects on aquatic wildlife and even human beings. More recent studies have shown that these alkylphenols may affect the molting processes and survival of crustacean species such as American lobster, crab and shrimp. In this study, we have developed gas chromatography with flame ionization detection (GC-FID) and gas chromatography- mass spectrometric (GC-MS) methods for the determination of bisphenol A and its analogues in shrimp Macrobrachium rosenbergii, blue crab Callinectes sapidus and American lobster Homarus americanus samples. Bisphenol A, 2,4-bis-(dimethylbenzyl)phenol and 4-cumylphenol were found in shrimp in the concentration ranges of 0.67-5.51, 0.36-1.61, and < LOD (the limit of detection)-1.96 ng/g (wet weight), and in crab of 0.10-0.44, 0.13-0.62, and 0.26-0.58 ng/g (wet weight), respectively. In lobster tissue samples, bisphenol A, 2-t-butyl-4-(dimethylbenzyl)phenol, 2,6-bis-(t-butyl)-4-(dimethylbenzyl)phenol, 2,4-bis- (dimethybenzyl)phenol, 2,4-bis-(dimethylbenzyl)-6-t-butylphenol and 4-cumylphenol were determined at the concentration ranges of 4.48-7.01, 1.23-2.63, 2.71-9.10, 0.35-0.91, 0.64-3.25, and 0.44-1.00 ng/g (wet weight), respectively. At these concentration levels, BPA and its analogs may interfere the reproduction and development of crustaceans, such as larval survival, molting, metamorphosis and shell hardening.
A REVIEW OF DEVELOPMENT ISSUES AS THEY APPLY TO CONSTRUCTION IT

The construction industry is widely characterised as conservative in both business practices and construction methods and processes. Companies are seen as reluctant to change existing practices, despite the potential for greater efficiency and time and cost savings offered by technology now available. Supply chains are fragmented, and extensive use of sub-contacting introduces layers of management and a strong degree of autonomy in a wide variety of subgroups within a construction project team. Many studies have focused on barriers to the uptake of information technology in construction firms, with findings often framed in terms of characteristics of the industry similar to those summarised above. This paper presents a review of literature related to the introduction of IT in construction. It highlights a number of related issues that indicate that the construction industry might be better seen as cautious, but making progress, rather than resistant. While there are clearly characteristics of the construction industry that hinder widespread uptake of information technology, this can be seen as only part of the story. The argument for increased application of IT to construction processes is now well established, with identified benefits of improved productivity, financial and environmental sustainability. There are clearly gains to be made from progression in the industry from low-level business applications to construction-specific IT usage, and there are indications that the industry is ready for this to take place. To conclude the paper, the author questions why these industry characteristics often cited as barriers to innovation are not instead regarded by the proponents and developers of construction IT as constraints or design issues to be factored into the development process.
Mean Age of Menarche in Trinidad and Its Relationship to Body Mass Index, Ethinicity and Mothers Age of Menarche

Menarche is the first menstrual period. It is the final event in the physical manifestation of gonadal development. A study in Europe found that the median age of menarche was 12 years and 11 months and that by the tenth year, 0.8% of the girls had their first menses, while the figure for the eleventh and twelfth years were 3.6 and 21.7% respectively. A Geneva study found that menarche was present in 50% at the age of 12.75 years. This study reported that, in the periods 1955-1980, the age of puberty has decreased by 0.5%, while the decrease between the periods 1965-1980 was 0.25%. Studies in the 70s and 80s found that African American girls were taller, heavier and maturing earlier than white girls of their age. Early menarche was observed in some of the girls by the age of 11 years, while all the girls were menstruating at the age of 15 years. Precocious puberty was defined as puberty before the age of eight years, while delayed puberty was defined as the absence of breast budding before the age of 14. However some pediatricians have concluded that the onset of breast development before the ages 7-8 years in white girls and between the ages of 6-7 years in African American girls may be part of the normal variation in the timing of puberty. It had been suspected that the decrease in the age of puberty is due to improved standard of living. However endocrine-disrupting chemicals from environmental pollutants are now seriously implicated as major factors in early puberty, while the ethnic factor has also been recognized. In this study, 489 students aged 15-17 selected from secondary schools from different areas of Trinidad were used. The data was collected through a questionnaire and the primary variable measured was the age of onset of menses. It also contained information on the ethnicity of the respondents. The heights and weights of the students were also measured. Results showed that, the mean age of menarche for Trinidadian girls was 11.71 years ±1.18. It also showed that the mean age for Blacks was 11.67±1.29, while that of Indians was 11.65±1.08. The mixed races’ mean, was 11.87±1.09. No significant difference was found in the mean age of menarche between Blacks and East Indians. The result also showed a decrease in the age of menarche with increased BMI. The mean age of menarche of the mothers of the students sampled was 12.57 years, which is significantly higher that that of their daughters. This is consistent with recent findings, which reported that the mean age of menarche has been decreasing over the years in all societies.
High Polarization HfO 2 Sensing on K + for Inflammasome Cell Detection Application

In this study, a novel method was proposed to detect the inflammasome activation from extracellular potassium ion concentration. The sensor platform was designed as the electrolyte insulator semiconductor (EIS) structure with fluorinated HfO2 sensing membrane. The potassium (K) sensitivity of HfO2-EIS structure is 10.28 mV/pK in the concentration between 10 M and 1 M. For the samples with fluorine (F) ion implantation, the pK sensitivity can be effectively improved to 56.02 mV/pK. The variation of K concentration under treatment with the nigericin was 64.65 mV. It takes the advantage of directly monitoring the alteration of K as the measurement indicator of inflammasome activation.

Anti-inflammatory and antioxidant potentiality of Solanum xanthocarpum

Inflammation is the body’s immune response to combat suspected harmful effect by a stimulus. Antioxidants prevent chain of reaction that would result in the production of free radicals. Prolonged usage of steroids as anti-inflammatory agents is unsafe, demanding search for anti-inflammatory compounds with sustainable future. In this study, seeds and leaves of Solanum xanthocarpum were explored in vitro for their anti-inflammatory and antioxidant activity. The ethanolic extract of seeds and leaves of S. xanthocarpum was prepared by maceration. Anti-inflammatory activity of ethanolic extract of seeds (SE) and leaves (LE) was evaluated in terms of percent inhibition of albumin denaturation, membrane stabilization and protease inhibition. The antioxidant activity was estimated by 2,2-diphenyl-1-picrylhydrantiiazyl (DPPH) free radical scavenging assay by exploiting 1,1-diphenyl-2-picrylhydrazine. Successive solvent extraction with maceration of seeds was carried out by using solvents ethanol, ethyl acetate, acetone and water. The ethanolic extracts of seeds and leaves of S. xanthocarpum demonstrates anti-inflammatory and antioxidant activity. The acetones extract exhibited potent anti-inflammatory activity than ethyl acetate and aqueous extract. Results presented here suggest that the S. xanthocarpum exhibits anti-inflammatory and antioxidant potentiality. Key words: Solanum xanthocarpum, anti-inflammatory, phytochemical and antioxidant activity.
Modulation of Tinnitus Loudness through Pinna Lifting and Ear Canal Obstruction

Objective: To study the effect on tinnitus loudness on lifting the pinna and obstructing the ear canal. Study Design: Consecutive, prospective case series Setting: Private practice (secondary referral centre) Patients: Patients presenting with tinnitus who hear their tinnitus at the time of the examination: 37patients with mean age 50.8. Intervention(s): Positioning the index finger in the entrance of the acoustic meatus and pulling theskin on the superior part of the entrance outward and upward, so as to exert a lifting effect on the crus helicis; and obstructing the ear canal with the index finger. Main Outcome Measure(s): Subjective evaluation of increase or decrease in tinnitus loudness during the manoeuvre. Results: On pulling the skin outward tinnitus loudness decreased in 11/37 patients to 61% on average; obstructing the ear canal led to a decrease in tinnitus loudness in 7 patients and an increase in 4 patients. Conclusions: both lifting the pinna by pulling the skin of the ear canal as well as obstructing the ear canal provoke a change in tinnitus loudness in many patients. The pathway through which these manoeuvres exert their effect is unclear; a somatosensory mechanism or an influence on middle ear acoustics might be involved.
LATE CENOZOIC ATMOSPHERIC CIRCULATION INTENSITY AND CLIMATIC HISTORY RECORDED BY EOLIAN DEPOSITION IN THE EASTERN EQUATORIAL PACIFIC OCEAN , LEG 138 1

Sediments recovered during Ocean Drilling Program (ODP) Leg 138 in the eastern equatorial Pacific Ocean were analyzed for variations in eolian accumulation rate and mean grain-size. Latitudinal and temporal patterns of these parameters showed important changes in the intensity of atmospheric circulation and eolian flux associated with the intertropical convergence zone (ITCZ) and suggested that eolian input parameters could be used to define its paleoposition through time. Modern atmospheric circulation in the equatorial region is weakest in the intertropical convergence zone and increases as the trade winds are approached to the north and south. Thus, the expected spatial pattern of eolian grain size would have the finest material deposited beneath the ITCZ and a coarsening of material in both directions away from this zone. Sediments from ODP Leg 138 show this pattern for much of the Pleistocene and Pliocene but, prior to about 4 Ma, begin to lose the northern coarse component suggesting that the ITCZ was located north of its present position during the late Miocene. Eolian flux records also show a latitudinal pattern of deposition associated with the position of the ITCZ that, similar to eolian grain-size variability, suggests a more northerly position of the ITCZ during the late Miocene. Overall, the regional input of eolian material to the equatorial Pacific has decreased throughout the late Neogene. This reduction in eolian input reflects climatic changes to relatively wetter conditions in the continental eolian source regions beginning during the late Pliocene.

Propagation of transient electromagnetic waves in inhomogeneous and dispersive waveguides

Transient wave propagation in a waveguide filled with an inhomogeneous dispersive medium is analyzed. The waveguide is inhomogeneous in the longitudinal direction, but is homogeneously filled in the transverse directions. The analysis is performed in the time domain and is based upon a wave splitting technique and the method of propagators. The propagator maps the exciting field from one position in the waveguide to the field at another position. This mapping is represented as time convolution integrals. The theory is exemplified by numerical examples where it is shown how wave trains of different shapes are propagating in a waveguide filled with a homogeneous dispersive medium.
Experimental and thermodynamic description of ternary Bi-Cu-Ga system

Phase diagram of the Bi-Cu-Ga ternary system has been investigated experimentally with 27 alloys and analytically by using a Calphad method. Thirteen annealed alloys at 200 °C were investigated by using scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) methods. Temperatures of phase transformation were determined with 14 alloys which are lying along three vertical sections Bi-Cu0.5Ga0. 5, Cu-Bi0.5Ga0. 5 and Ga-Bi0.5Cu0. 5 by using differential thermal analysis (DTA). Based on the experimental result and by using Calphad method, ternary phase diagrams were constructed with a new description of liquidus phase. Calculated phase diagram and experimentally obtained results are in good agreement. Liquidus projection and invariant reaction were calculated by using new thermodynamic parameters for liquidus phase.
Keynes’s relevance in the new millennium

This paper examines aspects of the economics of J M Keynes for the relevance that they may have to a number of current issues particularly those faced by central banks in the second half of 2008. In particular, we shall see that Keynes’s view of the importance of uncertainty in monetary economies is well-illustrated by the dilemma posed by the coincidence of recession and rising inflation rates. We shall also see that his view about the relationship between demand and what is fashionably described as the ‘natural rate’ of unemployment (and output) requires a radically different response from the one that current policymakers are likely to pursue. However, since the latest developments in macroeconomics, which will actually inform policymakers during this crisis, have been described as a ‘consensus’, which presumably incorporates ‘the best’ of Keynesian and other traditions in macroeconomics, we start by asking just how much ‘Keynes’ there really is in the new consensus macroeconomics.
Assessment of Current and Future Air Pollutant Emission Reduction Technologies for Marine Diesel Engines

Abstract : Defence Research and Development Canada (DRDC) has identified several air pollutant emission control technologies, which have potential for application to marine diesel systems. 3GA Marine Ltd (3GA) identified relevant technologies, including commercially available and developmental technologies. The technologies were catalogued, critically reviewed, and assessed to determine their maturity (Technology Readiness Level/TRL). It was concluded that a majority of identified technologies are mature and commercially available; however, some of them have a limited demonstration of performance. Only a few technologies were found to be new or emerging. Most of the air pollutant emission control technologies focus on reducing concentration of nitrogen oxides (NOx), sulphur oxides (SOx), or particulate matter (PM). Some reductions of concentration of the other air pollutants, including black carbon (BC), carbon monoxide (CO) or carbon dioxide (CO2) from the marine diesel systems is being achieved by these technologies. Several technologies can be used simultaneously to achieve the best and the most comprehensive reduction of air pollutants emissions from the marine diesel system. The study identified the factors particular to naval diesels and the fuel used by them, and indicated which of the technologies have highest potential for application in Canadian naval vessels. Use of alternative fuels may be a viable non-technological method of reducing emission of air pollutant, primarily NOx, PM, and CO2 from the marine systems.
Succession, diversity and trophic relationships of some soil animals in decomposing leaf litter

Soil systems contain some of the most species-rich communities in existence. Well developed temperate woodland soils may contain up to a thousand species of soil animals alone, including several hundred species of mites and Collembola, in populations exceeding 1 to 2 millions per square metre. Investigations of the interand intra-specific relationships within these immensely complex communities has proved to be one of the most intractable ecological problems. The study of microhabitat development and successional changes in soil organism communities during the breakdown and decomposition of organic materials in the soil could provide useful information towards an understanding of the larger system. Unfortunately few studies of this kind have been carried out. Succession of the soil microflora on leaves has been demonstrated in a number of studies (notably, Hogg & Hudson 1966; Frankland 1966; Hudson 1968, Parkinson & Balasooriya 1969; Jensen 1971) but there have been few investigations of the soil fauna associated with decomposing leaf litter. One major problem in studies of this type is in maintaining the identity of the experimental material without altering the soil environment. Crossley & Hoglund (1962) suggested that the use of litter bags would overcome this difficulty and this method has been used by Stevanovic (1968) to study general arthropod succession and by Metz & Farrier (1969) to study succession of the Mesotigmata (Acari) in leaf litter. Anderson (1973a, b) investigated the breakdown and decomposition of beech (Fagus sylvatica L.) and sweet chestnut (Castenea sativa Mill) litter using litter bags and found that beech leaves were less palatable to soil animals and more resistant to microbial decomposition than chestnut leaves. The present study is an analysis of the soil animal populations extracted from these litter bags over a 20-month period to investigate the successional development, structure and trophic relationships of soil organism communities in beech and chestnut leaves.
Dopamine Receptors Gene Expression in Male Rat Hippocampus after Administration of MDMA (Ecstasy)

El extasis es una de las drogas de diversion mas populares entre los jovenes. La investigacion reporta algunos de los efectos del extasis sobre el hipocampo y la relacion entre las funciones dopaminergicas con la recompensa en el aprendizaje. El objetivo de este estudio fue la evaluacion de los efectos cronicos del extasis en la memoria de ratas macho Wistar y la determinacion de la expresion de genes receptores de dopamina en el hipocampo. Cuarenta ratas macho adultas fueron distribuidas al azar en cinco grupos: grupo control, simulado (a 1 ml/kg 0,9% de solucion salina) y tres grupos experimentales: Grupo exp. 1 (2,5 mg/kg), Exp. 2 (5 mg/kg), y Exp. 3 (10 mg/kg) recibio MDMA via intraperitoneal cada 7 dias (3 veces al dia, con 3 horas de diferencia) durante 4 semanas. Antes de la primera inyeccion los animales fueron entrenados en memoria Shuttle Box y examinados despues de la ultima inyeccion. Veinticuatro horas despues de la prueba final, los cerebros de las ratas fueron diseccionados, el hipocampo fue separado y homogeneizado. Despues de la extraccion total de ARN y sintesis de ADNc, la expresion de genes de los receptores de dopamina en el hipocampo fue determinado con PCR en tiempo real. Nuestros resultados mostraron que los grupos de 2,5 kg y 5 mg/MDMA tratados tenian deterioro de la memoria. Ademas, encontramos que la MDMA aumento la expresion de ARNm de los receptores de dopamina en el hipocampo y el aumento mayor se observo en los receptores D1 de dopamina en el 5 mg/kg Grupo experimental. En conclusion, las dosis bajas de extasis podrian aumentar tomadores de expresion genica de la dopamina en el hipocampo y trastornos de la memoria. Sin embargo, en dosis altas el aumento de la expresion genica no mostro un aumento significativo, a diferencia de los resultados con dosis bajas, tampoco se observaron trastornos disociativos de memoria.
Orbital solutions of eight close sdB binaries and constraints on the nature of the unseen companions

The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars (sdBs) with massive compact companions such as white dwarfs, neutron stars, or stellar-mass black holes. In a supplementary programme we obtained time-resolved spectroscopy of known hot subdwarf binary candidates. Here we present orbital solutions of eight close sdB binaries with orbital periods ranging from ∼0.1 d to 10 d, which allow us to derive lower limits on the masses of their companions. Additionally, a dedicated photometric follow-up campaign was conducted to obtain light curves of the reflectioneffect binary HS 2043+0615. We are able to constrain the most likely nature of the companions in all cases but one, making use of information derived from photometry and spectroscopy. Four sdBs have white dwarf companions, while another three are orbited by low-mass main sequence stars of spectral type M.
