This study investigates the association between remittances, FDI, energy use, and CO2 emissions for a sample of the top six Asian nations receiving remittances, namely, China, India, the Philippines, Pakistan, Bangladesh, and Sri Lanka, during the 1982–2014 period. The results of employing an autoregressive distributed lag (ARDL)-bound technique signify that there is a stable long-run association among the stated variables. The empirical findings indicate that CO2 increases significantly with a rise in energy use in all sample nations in both the long and short-runs. Conversely, the association between CO2 emissions and remittances is found to be significantly positive for Sri Lanka, Pakistan, the Philippines, and Bangladesh in the long-run, positive for Pakistan, the Philippines, and Sri Lanka only in the short-term, and non-significant for India and China in both the long and short-runs. Furthermore, the empirical results illustrate that the inflow of FDI significantly increases CO2 emissions in the cases of China, Sri Lanka, and India in both the long and short-runs. While FDI inflow has no significant effect on CO2 emissions for the Philippines and Pakistan, it has a significant negative effect for Bangladesh in both the long and short-runs. Thus, the connection between remittances, FDI, and CO2 emissions varies significantly across the countries considered in our study.

The Kouchibouguac Bay barrier island – sand spit system is the simplest of the four large systems in the southern part of the Gulf of St. Lawrence, and occupies a relatively low wave energy environment. Present field evidence and information from a series of maps published since 1807 and a series of air photographs taken since 1930 indicate that the barriers have undergone considerable changes over the last 160 years. The changes involve shoreward retreat and repeated breaching and infilling of a series of temporary inlets. The three main inlets in the system have remained relatively constant in overall position during this period, but there have been marked local variations in the associated channels and shoals. In general terms the Kouchibouguac barriers may be considered as representative of other systems in the southern part of the Gulf of St. Lawrence and present strong similarities to the well documented barriers of the eastern coast of the United States.

Energy inputs are a major production cost for greenhouse-grown plants, especially heating and supplemental lighting. A possible energy-efficient alternative is to optimize greenhouse conditions on days that have a low heating demand and reduce temperature and irradiance on days that have a high heating demand. The objectives of this study were to determine how many days per week annual bedding plants could be grown in a reduced-energy environment before delays in crop growth and flowering occurred and to calculate the potential energy savings. Angelonia (Angelonia angustifolia Benth. ‘Angelface Blue’), dianthus (Dianthus chinensis L. ‘Telstar Pink’), lantana (Lantana camara L. ‘Luscious Citrus Blend’), pansy (Viola ×wittrockiana Gams. ‘Matrix Blue Blotch’), petunia (Petunia ×hybrida Vilm. ‘Supertunia Mini Strawberry Pink Veined’), and petunia ‘Supertunia Vista Bubblegum’ were grown in a “winter-normal” (WN) greenhouse (22/18 °C day/night, supplemental lighting from high-pressure sodium (HPS) lamps, 14-hour photoperiod) and transferred to a “winter low-energy” (WLE) greenhouse (13/10 °C day/night, energy curtain continuously closed, day-extension lighting with HPS lamps, 14-hour photoperiod) for 0, 1, 2, 4, or 7 days per week. In general, days to first flower (DTFF), flower number, plant height, plant width, relative chlorophyll content, and shoot dry weight decreased as exposure duration to WLE increased. Flowering on angelonia was delayed when grown 1 day per week in WLE; delayed on dianthus, petunia ‘Supertunia Mini Strawberry Pink Veined’, and lantana when grown 4 days per week in WLE; and delayed on petunia ‘Supertunia Vista Bubblegum’ when grown continuously in WLE. Energy costs were estimated using Virtual Grower 3.0.9, and average savings of 2% to 8% occurred with 1 day per week in WLE, and increased to 35% to 51% when plants were grown continuously in WLE.

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.

Short term experimental and clinical preservation of kidneys is presently best accomplished by hypothermic continuous pulsatile perfusion with cryoprecipitated and millipore filtered plasma. This study was undertaken to observe ultrastructural changes occurring during 24-hour preservation using the above mentioned method.A kidney was removed through a midline incision from healthy mongrel dogs under pentobarbital anesthesia. The kidneys were flushed immediately after removal with chilled electrolyte solution and placed on a LI-400 preservation system and perfused at 8-10°C. Serial kidney biopsies were obtained at 0-½-1-2-4-8-16 and 24 hours of preservation. All biopsies were prepared for electron microscopy. At the end of the preservation period the kidneys were autografted.

Polychlorinated biphenyls (PCBs) are a ubiquitous class of environmental pollutants with toxic and hepatocellular effects, including accumulation of fat, proliferated smooth endoplasmic recticulum (SER), and concentric membrane arrays (CMAs) (1-3). The CMAs appear to be a membrane storage and degeneration organelle composed of a large number of concentric membrane layers usually surrounding one or more lipid droplets often with internalized membrane fragments (3). The present study documents liver alteration after a short term single dose exposure to PCBs with high chlorine content, and correlates them with reported animal weights and central nervous system (CNS) measures. In the brain PCB congeners were concentrated in particular regions (4) while catecholamine concentrations were decreased (4-6). Urinary levels of homovanillic acid a dopamine metabolite were evaluated (7).Wistar rats were gavaged with corn oil (6 controls), or with a 1:1 mixture of Aroclor 1254 and 1260 in corn oil at 500 or 1000 mg total PCB/kg (6 at each level).

Toxic Responses

Introduction. Experimental induction of altered histology by chemical toxins is of particular importance if its outcome resembles histopathological phenomena. Hepatotoxic drugs and chemicals are agents that can be converted by the liver into various metabolites which consequently evoke toxic responses. Very often, these drugs are intentionally administered to resolve an illness unrelated to liver function. Because of hepatic detoxification, the resulting metabolites are suggested to be integrated into the macromolecular processes of liver function and cause an array of cellular and tissue alterations, such as increased cytoplasmic lysis, centrilobular and localized necroses, chronic inflammation and “foam cell” proliferation of the hepatic sinusoids (1-4).Most experimentally drug-induced toxicity studies have concentrated primarily on the hepatic response, frequently overlooking other physiological phenomena which are directly related to liver function. Categorically, many studies have been short-term effect investigations which seldom have followed up the complications to other tissues and organs when the liver has failed to function normally.

Previous short term toxicological studies of one to two weeks duration have demonstrated that MDL 19,660 (5-(4-chlorophenyl)-2,4-dihydro-2,4-dimethyl-3Hl, 2,4-triazole-3-thione), an antidepressant drug, causes a dose-related thrombocytopenia in dogs. Platelet counts started to decline after two days of dosing with 30 mg/kg/day and continued to decrease to their lowest levels by 5-7 days. The loss in platelets was primarily of the small discoid subpopulation. In vitro studies have also indicated that MDL 19,660: does not spontaneously aggregate canine platelets and has moderate antiaggregating properties by inhibiting ADP-induced aggregation. The objectives of the present investigation of MDL 19,660 were to evaluate ultrastructurally long term effects on platelet internal architecture and changes in subpopulations of platelets and megakaryocytes.Nine male and nine female beagle dogs were divided equally into three groups and were administered orally 0, 15, or 30 mg/kg/day of MDL 19,660 for three months. Compared to a control platelet range of 353,000- 452,000/μl, a doserelated thrombocytopenia reached a maximum severity of an average of 135,000/μl for the 15 mg/kg/day dogs after two weeks and 81,000/μl for the 30 mg/kg/day dogs after one week.

Thermodynamic Framework

Volume is a highly regulated property of cells, because it critically affects intracellular concentration. In the present chapter, we focus on the short-term volume regulation in yeast as a consequence of a shift in extracellular osmotic conditions. We review a basic thermodynamic framework to model volume and solute flows. In addition, we try to select a model for turgor, which is an important hydrodynamic property, especially in walled cells. Finally, we demonstrate the validity of the presented approach by fitting the dynamic model to a time course of volume change upon osmotic shock in yeast.
