Comparison of Thermal and Microwave Paleointensity Estimates in Specimens Displaying Non‐Ideal Behavior in Thellier‐Style Paleointensity Experiments

Determining the strength of the ancient geomagnetic field is vital to our understanding of the core and geodynamo, but obtaining reliable measurements of the paleointensity is fraught with difficulties. Over a quarter of magnetic field strength estimates within the global paleointensity database from 0 to 5 Ma come from Hawaii. Two previous studies on the SOH1 drill core gave inconsistent, apparently method‐dependent paleointensity estimates, with an average difference of 30%. The paleointensity methods employed in the two studies differed both in demagnetization mechanism (thermal or microwave radiation) and Thellier‐style protocol (perpendicular and original Thellier protocols)—both variables that could cause the strong differences in the estimates obtained. Paleointensity experiments have therefore been conducted on 79 specimens using the previously untested combinations of thermal‐perpendicular and microwave‐original Thellier methods to analyze the effects of demagnetization mechanism and protocol in isolation. We find that, individually, neither demagnetization mechanism nor protocol entirely explains the differences in paleointensity estimates. Specifically, we found that non‐ideal multidomain‐like effects are enhanced using the original Thellier protocol (independent of demagnetization mechanism), often resulting in paleointensity overestimation. However, we also find evidence, supporting recent findings from the 1960 Kilauea lava flow, that microwave‐perpendicular experiments performed without partial thermal remanent magnetization checks can produce underestimates of the paleointensity due to unaccounted‐for sample alteration at higher microwave powers. Together, these findings support that the true paleointensities fall between the estimates previously published and emphasize the need for future studies (thermal or microwave) to use protocols with both partial thermal remanent magnetization checks and a means of detecting non‐ideal grain effects.
Oral Methadone for Cancer Pain Management at the End of Life: A Forgotten Drug

Background: Opioids are used for pain management in cancer patients. Morphine is considered the best option. For some patients with pain of difficult control management and adverse effects, an opioid rotation should be considered. Oral methadone is an opioid to which patients can be rotated safely and effectively and inexpensive for Mexico and Latin America. Our study describes the 9-year experience of opioid rotation to methadone, the population profile, efficacy of methadone in cancer patients of the palliative care service. Methods: Retrospective study of cancer patients rotated to oral methadone for pain control. Tables of frequencies, median and interquartile ranges were made, as well as overall survival. Results: 311 patients were rotated to methadone, predominantly males (58.5%), median age of 54 years with oncological diagnoses in cervix (10.3%), germinal tumors (8.4%), breast (8.0%), prostate (7.4%) and rectal (5.5%). These patients experienced visceral (17.6%) or other types of pain (68.6%), and a combination of different types of pain, the most prevalent pain was neuropathic (88.7%) and 50% received morphine, 21% buprenorphine or fentanyl 19% previously, with a median dose of 60 mg (30-120). The main reason for rotation was difficult pain control (54%), obtaining an efficacy of 70.0%. Conclusion: In this cohort at advanced disease stage, 54% suffered from difficult pain control, thus rotation became necessary, reducing pain and manageable adverse events, without major changes of the initial and final dose. Should be promoted more widely in the management of pain of difficult control by cancer in first position prescription.
The Rough Estimate of the Nuclear Space Occupied by Nucleolar Bodies in Lymphocytes of Patients Suffering from B Chronic Lymphocytic Leukemia and Blood Donors

It is generally known that the nucleus : cytoplasmic ratio is a very useful marker for the evaluation of the cell activity and identification. In contrary, the nucleolus : nucleus ratio was less studied. The present study was undertaken to provide more information on that ratio during the differentiation and maturation of human lymphocytes. The ratio of nucleolar bodies to the nuclear body indicated that the size of the nuclear space occupied by nucleolar bodies in B chronic lymphocytic leukemia (CLL) during the cell differentiation and maturation (terminal differentiation) decreased in both untreated and treated patients with the anti-leukemic therapy. However, the nuclear space occupied by nucleolar bodies was apparently characteristic for each differentiation and maturation step. A similar trend was apparent in non-leukemic T lymphocytes of blood donors using in vitro de-differentiated lymphocytes as progenitors. During the cell differentiation and maturation, the size reduction of nucleolar bodies of both patients suffering from CLL and blood donors was apparently larger than that of the nucleus. As it was expected, the decreased size of nucleolar bodies was accompanied by the decreasing nucleolar transcription activity expressed by the reduced number of fibrillar centers.
Bacterial contamination of toilet door handles on Baze University campus Abuja Nigeria

Aim : Contracting infectious diseases from microbial contaminated toilet door handles is a potential threat to public health and safety. Therefore we performed microbiological screening of toilet door handles in twelve рublic toilets on Baze University campus for bacterial contamination. Methodology and Results : Biochemical analysis of bacterial isolates from entrance toilet door handles in six building blocks on Baze University camрus, revealed a general contamination by mainly seven bacterial species associated with human gut and skin flora in order of decreasing frequency as follows: Staphylococcus aureus 42.9%; Salmonella typhimurium 21.4%; Escherichia coli 14.3%; Pseudomonas aeruginosa 9.5%; Proteus mirablis 4.8%; Klebsiella oxytoca 4.8%; and Klebsiella pneumoniae with 2.3% prevalence. Results of the total aerobic mesophillic count showed A-Block with the highest amount of contamination – 768*10 5 CFU/ml, while B-Block had the least amount of bacterial contamination – 473*10 5 CFU/ml. The levels of bacterial contamination in the other blocks were as follows: C-Block – 710*10 5 CFU/ml, D-Block – 695*10 5 CFU/ml, E-Block – 567*10 5 CFU/ml, and FBlock – 743*10 5 CFU/ml. Conclusion : Overall of the seven isolated bacterial sрecies five were mainly gut-associated bacteria, suggesting feacal contamination. The others were skin-associated bacteria ( Staphylococcus aureus ), suggesting routine touch by hands, and soil-associated bacteria ( Pseudomonas aeruginosa ) suggesting contamination from settling dust рarticles. This study is relevant for public health and safety, as its findings reveal the presence of bacterial pathogens on toilet door handles, which is vital in preventing the spread of infectious disease. Keywords : Toilet door handles, bacterial pathogens, fecal contamination, antibiotic resistance.
Competitive growth in a social fish

Many animal societies have dominance hierarchies in which social rank is correlated with size. In such societies, the growth and size of individuals can be a strategic response to their social environment: in fishes, individuals may decrease their growth rate to remain small and retain a subordinate position; in mammals, individuals may increase their growth rate to become large and attain a dominant position—a strategy called competitive growth. Here, we investigate whether the clown anemonefish, Amphiprion percula, exhibits competitive growth also. We show that juvenile clownfish paired with a size-matched reproductive rival increase their growth rate and size relative to solitary controls. Remarkably, paired individuals achieved this, despite being provided with the same amount of food as solitary controls. Our results demonstrate that clownfish are able to increase their growth rate in response to social competition. This study adds to the growing body of evidence that the growth of social vertebrates can be a fine-tuned plastic response to their social environment.
Detection of Coronary Artery Anomaly in Tetralogy of Fallot: Comparison of Two Angiographic Views

Background: The definite treatment of tetralogy of Fallot (TOF) as the most common cyanotic congenital heart disease is open heart surgery and the operation technique depends on the coronary artery anatomy. Objectives: We aimed to evaluate the sensitivity and specificity of various root Aortogram views to detect abnormal coronary artery configuration and course in these patients. Methods: In this retrospective study, the reports of coronary anatomy in angiography and operation notes of TOF patients since 2005 to 2018 were evaluated. The sensitivity and specificity of the two common root Aortogram views including the left anterior oblique/cranial (LAO/CRA) and left anterior oblique/caudal (LAO/CAU) were determined. Results: Four hundred and fifty one patients with the median age of 28 months (3 - 432 months) were included. All patients had LAO/CRA views and 199 patients had both LAO/CRA and LAO/CAU views. The rate of coronary abnormalities reported by surgery was 8%, and abnormal origin of the left anterior descending artery from the right coronary artery was the most common reported anomaly (4.4%). The sensitivity of the LAO/CAU view was 100%, but LAO/CRA view was about 75% in detecting abnormal coronary configuration. Both of them had excellent specificity (~100%). No significant sex difference was seen between different coronary anatomy abnormalities. Conclusions: The Caudal root angiogram is an essential view to evaluate coronary artery anatomy in TOF patients and it seems that there is no need for other views like lateral view, but relying on LAO/CRA view alone may lead to significant misdiagnosis of the coronary arteries, crossing the right ventricular outflow tract (RVOT).
Cytotoxic Effects of Coated Gold Nanoparticles on PC12 Cancer Cell

Background: The use of gold nanoparticles in medicine and especially in cancer treatment has been of interest to researchers. The effectiveness of this nanoparticle on cells significantly depends on the amount of its entry into the cells. This study was performed to compare the rate and mechanism of effect of gold nanoparticles coated with different amino acid on PC12 cancer cell line. Materials and Methods: The PC12 cells line were exposed to various concentrations of amino acid coated and uncoated gold nanoparticles (0.5, 2.5 and 5 μM). Cell death rate was determined according to level of Lactate dehydrogenase (LDH) release from cells and MTT assay. In addition cell morphology and the amount of Cellular Reactive oxygen species (ROS) were studied. Results: The uncoated gold nanoparticles have shown minor effects on cellular life. Gold nanoparticles coated by tryptophan at high concentrations (2.5, 5 and 25μM) increase in cancer cells metabolic activity. Gold nanoparticles coated by Aspartate also produce the largest amount of LDH and ROS in cancer cells and therefore caused of highest rate of apoptosis. Conclusion: The results showed that the nanoparticles coated with amino acids are affected on cellular metabolism and apoptosis more than uncoated nanoparticles. Also the smallest coated nanoparticles (coated by aspartate) have the most influence and by increasing the size, this effect was reduced.
Benefit Communication and Its Effects on Employees’ Benefit Level Satisfaction: The Multiple Mediating Effects of POS and Benefit Comparison

Many firms offer employees a broad range of benefits as part of their compensation. However, little attention has been given to the extent to which firms communicate with their employees in relation to such benefits. This study proposes that benefit communication can have both direct and indirect positive effects on employees’ benefit level satisfaction. The effects of benefit communication were examined by means of a survey among 828 employees of different Spanish firms. This study hypothesized and found that benefit communication led to increased benefit level satisfaction. Similarly, this study found that benefit communication can influence benefit level satisfaction through the multiple intermediating effects of employees’ perceived organizational support and employees’ comparison of their benefits with those of referent others. These results imply that academics and practitioners must pay attention to providing adequate benefit communication in order to ensure the effectiveness of benefits.
Electron‐Driven Magnetic Dip Embedded Within the Proton‐Driven Magnetic Dip and the Related Echoes of Butterfly Distribution of Relativistic Electrons

In this study, a magnetic dip event in which a small‐scale magnetic dip is embedded within a large‐scale magnetic dip is analyzed based on the observations of the Van Allen Probes. The small‐scale dip is contributed by a sharp electron injection at the energy range of 1 to 10 keV, but the large‐scale dip is contributed by a smooth proton injection at the energy range higher than 10 keV. The formation of dip caused by the suprathermal electrons is supported by the self‐consistent magnetic model. Moreover, the echoes of butterfly distributions of relativistic electrons at the energy range of 0.5 to 3.4 MeV is observed. The time separations of the neighboring butterfly distributions are comparable to the drift periods of the electrons at the different energies. We suggest that the potential nonadiabatic processes in response to the magnetic dips possibly account for the butterfly distribution echoes.
Sustainable Corporate Ownership Structures and Earnings Management in the Vietnamese Stock Market

We conducted an empirical analysis to verify the relationship between companies’ ownership structures and earnings management. Our sample included 480 nonfinancial companies listed on Vietnam’s Ho Chi Minh Stock Exchange and Hanoi Stock Exchange from 2012 to 2017, and our explanatory variables included several ratios, such as the controlling shareholders’ stake, management ownership stake, state-owned stake, and foreign ownership stake, which represent different ownership structures. We examined the effects of these ratios on earnings management. Our results suggested that earnings management has a significant linear relationship with the state-owned and foreign ownership stakes. Our results can enhance the understanding of the role of companies’ sustainable ownership structures in limiting earnings management, and they can contribute to future studies of the relationship between earnings management and corporate social responsibility and sustainability reporting assurance practices that focus on corporate ownership structures.
Comparison of Musculoskeletal Disorder Risk based on Gender in High School Students

In Indonesia, there is a tendency for the emergence of musculoskeletal disorders (MSDs) in school-aged children. MSDs can cause disruption of daily activities, such as lost school time. Individual factors such as sex can be the cause of MSDs. This study aims to determine how much gender differences affect the risk of musculoskeletal disorder. The design of this research was analytic observative with cross-sectional approach. The population is all high school students in the Kec. Kramat Jati East Jakarta as many as 4,708 students. The research sample was 370 class XI students. Samples were taken by simple random sampling. The independent variable is gender while the dependent variable is MSDs. Retrieval of data by filling out the Nordic Body Map questionnaire. Data were processed univariately and bivariately with chi-square test. The results showed that there was a relationship between sex and musculoskeletal disorder. The value of p = 0,000 with a PR value = 1,131 and 95% CI = 1,051 - 1,217 which shows that female are more at risk 1,131 times having musculoskeletal disorder compared to male.
Exploring the limitations of event-related potential measures in moving subjects. Case studies of four different technical modifications in ergometer rowing

Measuring brain activity outside the laboratory is of great importance for investigating human behavior under naturalistic conditions (e.g., in cognition and movement research, application of brain-computer interfaces). To measure neuronal activity in moving subjects, only modified NIRS and EEG systems are applicable. Because conventional EEG systems are too sensitive to movement artifacts, artifact sources should be eliminated beforehand to improve signal quality. Four different approaches for EEG/ERP measures with moving subjects were tested in case studies: (i) a purpose-built head-mounted preamplifier, (ii) a laboratory system with active electrodes, (iii)+(iv) a wireless headset combined with (iii) passive or (iv) active electrodes. A standard visual oddball task was applied during rest (without movement) and during ergometer rowing. All 14 measures revealed very similiar (within subjects) visual evoked potentials for rowing and rest. The small intraindividual differences between rowing and rest, in comparison to the typically larger interindividual differences in the ERP waveforms revealed that ERPs can be measured reliably even in an athletic movement like rowing. The expected modulation of the motor-related activity by force output, on the other hand, was largely affected by movement artifacts. Therefore, for a successful application of ERP measures in movement research, further developments to differentiate between movement-related neuronal activity and movement-related artifacts are required. However, it cannot be excluded that activities with small magnitudes related to motor learning and motor control cannot be detected because they are superimposed by the very large motor potential which increases with force output.
Comparative Analysis of Properties of Particleboards Made from Corn Cobs at Varying Proportions of Clay Soil

Particles of dried corn cobs were employed for manufacture of cement bonded particleboards. Two types of clay soil (red and white) were used as supplement with cement to manufacture cement bonded particleboards. The production of the boards was done at varying proportions of 50/50/0, 50/40/10, 50/30/20, 50/20/30, 50/10/40 and 50/0/50 for (corn/cement/clay) in weight to weight basis while the other considerable production factors like nominal density and curing agent percentage remained constant at 1.30 g/cm3 and 3%. The chemical composition of the soil such as pH, organic carbon, organic matter, total nitrogen, and exchangeable bases were determined. Its impact on physical and mechanical properties such as density, water absorption, thickness swelling, modulus of rupture and modulus of elasticity were also investigated The results of the analysis of variance shows that all considerable production factors for the cement bonded particleboards were significant at 5% level of probability except clay soil type for density. The results show that cement bonded particleboard made of red clay soil with higher content of exchangeable bases proves better outstanding performance in density, strength and dimensional properties than the white clay soil. Among the cement bonded particleboards made at varying proportions. It was discovered that boards of 50/20/30 (corn/cement/clay) had better strength properties than others. Also, the boards made at the proportions of 50/40/10, 50/10/40 and 50/30/20 (corn/cement/clay) were better dimensionally stabled in moisture exposure but weak in strength. The outcome of this study may serve as a guideline for any manufacturer who intends to use clay soil as supplement for production of particleboards.
