Crude palm oil (CPO) is thought to be the most produced and consumed vegetable oil globally. However, when oil palm is grown using pesticides, it may contain OCP residues, which could be hazardous to humans due to their bioaccumulation in the body. For this reason, this study was conducted. Over the course of six months, the processed CPO (n = 18) was gathered once a month from the oil palm plantations owned by JP, Calaro, and Mrs. P. (control). The samples underwent analysis using gas chromatography mass spectrometry (GC-MS/MS) to detect the presence of organochlorinated pesticides (OCPs). Di

Abstract:
Abstract The writers conducted experiments in a test heat exchanger system to evaluate ten non-chemical scale and corrosion control devices. These devices are claimed to perform either by electrostatic, magnetic, electronic or catalytic mechanisms. Tests were also performed using chemicals to compare the results with non-chemical systems and to insure that the test conditions were not so severe that scale prevention was impossible. Water from a single deep well was used in all the tests. This water was known to cause calcium carbonate scale when heated. The test heat exchanger was a 2-tube she

Abstract:
Abstract With the advancement in green technology-based energy generation to achieve net-zero emissions, geothermal energy has been considered one of the options to reduce the carbon footprint from oil/gas production. In this paper, geothermal energy refers to energy generation that involves a high-pressure, high-temperature (HPHT) environment. Both geothermal energy generation and oil and gas production in such environments—which includes the use of steam-flooded wells and geothermal wells are always challenging as a result of operational issues caused by inorganic scale formation.

Abstract:
Calcium signaling pathways play pivotal roles in regulation of various important biological processes in eukaryotes ranging from yeast to human. Because of the high degree in gene conservation from yeast to human, the small molecule inhibitors discovered in the yeast based-drug screening system can be expected to exert their function in human as well. The immunosuppressive agents, FK506 and cyclosporine A, are an example. Our previous studies using a zds1 yeast-based assay to search for inhibitors in the calcium signaling pathway in Saccharomyces cerevisae mutant strain from the crude extract

Cedrela odorata is one of the most important commercial Neotropical forestry species, harvested mainly from natural forest, what have taken the species to danger of extinction. Its commercial plantation is limited by Hypsipyla grandella attacks, which could reach 100% of individuals in a forest plantation (Figure 1). Inverse relation of available calcium concentration in the soil for C. odorata and attacks of H. grandella had been reported (da Silva et al., 2009). Some studies indicate that calcium and boron addition to the soil has a positive e ect in height growth of Swietenia macrophylla (d

Abstract:
In part one of this deliverable, an ensemble of 14 CMIP6 Earth System Models is evaluated regarding their performance in simulating alkalinity and related parameters. The majority of the models and the multi-model-mean underestimate surface alkalinity compared to climatological observations. Alkalinity biases stemming from the parametrization of calcium carbonate formation and dissolution can be as big as biases stemming from model physics. In part two, we test the sensitivity of parametrizations concerning the carbonate chemistry in the FESOM2.1-REcoM3 and give recommendations for addressing

Highly asymmetric somatic hybrid plants were obtained by PEG/DMSO fusion of gamma irradiated (100, 250, 7500 and 1000 Gy) protoplasts of a (KmR-) interspecific hybrid Lycopersicon esculentum x L. pennellii (EP) with protoplasts of eggplant (E). Somatic hybrid calli were selected based on kanamycin resistance and verified by PCR of the NptII gene, RAPD's and Southern's using potato rDNA pTHG2 probes. Flow cytometry indicated all hybrid calli that did not regenerate shoots were 5-9n. Three asymmetric plants regenerated only from callus close to 4n and such calli oly occurred when EP received 100

Abstract:
Proteins are important macromolecules responsible for a variety of processes in living organisms. One of the most important features of proteins is their ability to respond to environmental stimuli, such as changes in intracellular metal concentration by binding metal ions, which in turns triggers structural changes within the protein that can modify its function or allow the protein to participate in a signaling pathway. One such signaling protein is the so-called neuronal calcium sensor 1 protein or NCS1, which binds Ca2+ along with other abiogenic metals such as Li+, and the metal binding r

Abstract:
We assess the quantitative relevance of expectations-driven sovereign debt crises, focusing on the Southern European crisis of the early 2010s and the Argentine default of 2001. The source of multiplicity is the one in Calvo (1988). Key for multiplicity is an output process featuring long periods of either high growth or stagnation that we estimate using data for those countries. We find that expectations-driven debt crises are quantitatively relevant but state dependent, as they only occur during stagnations. Expectations are a major driver explaining default rates and credit spread differenc

Abstract:
The shallow aquifer in the Fox Creek area is hosted by the Paleocene Paskapoo Formation. The formation consists of fluvial deposits with channel-filled high-energy sandstone cutting through fine-grained, low energy overbank sediments. Three internal members are recognized, these members define three hydrostratigraphic units (two aquifers versus one aquitard). In fall 2022, three boreholes were drilled and cored. The succession is slightly dominated by sandstone with subordinate fine-grained sediments and thin coal intervals. The calcareous to non-calcareous sandstone is either tight and well c

Abstract:
Moths constitute a major group of pest insects in agriculture. Pheromone blends are utilised by a variety of moth species to attract conspecific mates, which is under circadian control by the neurohormone, PBAN (pheromone-biosynthesis-activating neuropeptide). Our working hypothesis was that, since the emission of sex-pheromone is necessary to attract a mate, then failure to produce and emit pheromone is a potential strategy for manipulating adult moth behavior.
