Background: Hyperthyroidism was long considered a protective factor for the development of thyroid cancer. The association between hyperactive thyroid and cancer was rare. More recent studies have highlighted an association between hyperthyroidism and development of cancers, especially thyroid cancer. Given the lack of publication on the association of hyperthyroidism and thyroid cancer in the Democratic Republic of Congo (DRC), the present study was carried out to confirm the existence of this association in Congolese hospitals. Methods: This is a retrospective and descriptive study, which involved 106 cases of thyroid cancer recorded in the anatomopathology registers of four laboratories in the city of Kinshasa between 2005 and 2019. The p-value <0.05 was considered as the threshold of statistical significance. Results: Out of 106 cases of thyroid cancer, the association of hyperthyroidism and thyroid cancer was found in 5 cases (4.7%) (3.6% for women vs. 9% for men). The mean age of patients with this association was 51 ± 11 years. Papillary carcinoma (two cases), follicular carcinoma (two cases) and lymphoma (one case) were the types of cancer encountered. Etiologically, toxic multinodular goiter (four cases: 80%) and toxic adenoma (one case: 2%) were found. Conclusion: There is an association between hyperthyroidism and thyroid cancer in the Congolese hospital setting. There is a predominance of the female gender. There were an equal number of papillary and follicular carcinomas. With this study, we hope to encourage clinicians to thoroughly evaluate any suspicious nodule associated with hyperthyroidism.
How Good is the Density-Corrected SCAN Functional for Neutral and Ionic Aqueous Systems, and What is so Right about the Hartree-Fock Density?
Authors: Dasgupta Saswata , Shahi Chandra , Bhetwal Pradeep , Perdew John P. , Paesani Francesco
Published: April 2022

Density functional theory (DFT) is the most widely used electronic structure method, due to its simplicity and cost effectiveness. The accuracy of a DFT calculation de- pends not only on the choice of the density functional approximation (DFA) adopted but also on the electron density produced by the DFA. SCAN is a modern functional that satisfies all known constraints for meta-GGA functionals. The density-driven errors, defined as energy errors arising from errors of the self-consistent DFA electron density, can hinder SCAN from achieving chemical accuracy in some systems, including water. Density-corrected DFT (DC-DFT) can alleviate this shortcoming by adopting a more accurate electron density which, in most applications, is the electron density obtained at the Hartree-Fock level of theory due to its relatively low computational cost. In this work, we present extensive calculations aimed at determining the accuracy of the DC-SCAN functional for various aqueous systems. DC-SCAN (SCAN@HF) shows remarkable consistency in reproducing reference data obtained at the coupled cluster level of theory, with minimal loss of accuracy. Density-driven errors in the description of ionic aqueous clusters are thoroughly investigated. By comparison with the orbital-optimized CCSD density in the water dimer, we find that the self-consistent SCAN density transfers a spurious fraction of an electron across the hydrogen bond to the hydrogen atom (H⋆, covalently bound to the donor oxygen atom) from the acceptor (OA) and donor (OD) oxygen atoms, while HF makes a much smaller spurious transfer in the opposite direction, consistent with DC-SCAN (SCAN@HF) reduction of SCAN over-binding due to delocalization error. While LDA seems to be the conventional extreme of density delocalization error, and HF the conventional extreme of (usually much smaller) density localization error, these two densities do not quite yield the conventional range of density-driven error in energy differences. Finally, comparisons of the DC-SCAN results with those obtained with the Fermi-Lowdin orbital self-interaction correction (FLOSIC) method show that DC-SCAN represents a more accurate approach to reducing density-driven errors in SCAN calculations of ionic aqueous clusters.
A Prototype Software Tool to Comprehensively Address the Routine Biochemistry Laboratory Computations
Authors: Bassa Babu
Published: April 2022

Students and others beginning work in a life sciences laboratory are generally not at ease in designing experiments and performing necessary calculations for the preparation of reagents and test solutions. Some of the difficult points include the preparation of buffers at the right molarities and pH and the serial dilution of test compounds to achieve desired final concentrations. Valuable time and large sums of money are spent on experiments, therefore, a fool-proof method that precludes human errors in the design of the experiment and the preparation of the reagents is desired. The software tool, developed by the author and referred to as “Prototype-A-1” in this communication, meets this goal to a larger extent. The user of this software tool enters only readily available variables into the program and performs no prior computations. Modification of the basic dilution equation to facilitate the programming of serial dilutions is one of the major accomplishments of this program. Some important functions of the program are: (a) to generate custom instructions for the preparation and dilution of solutions with minimum inputs from the user; (b) to provide 25 custom buffer calculators; (c) to provide a protocol-writer for writing protocols for cell culture testing, antibody titrations, compound assays and animal experimentation. In this program, in all cases, the user enters only numbers from the keyboard or the keypad and selects units from the keypad menu. The user can enter stock and final concentrations in different standard units. The program requests the molecular weight of the compound when required and performs the necessary conversions. The program verifies the serial dilution instructions for accuracy by calculating the dilution factor from the mixing instructions of the output. In most cases of the queries, the output includes a display of the actual calculations. Windows 10 or higher operating system is required. The results of the queries and protocols generated can be saved as Microsoft Windows documents. The saved documents can be retrieved also by Microsoft’s word, WordPad and Notepad. A free trial version of the software tool is available at github.com/bbassa9824/Prototype-A-1. Downloading instructions are given in the “Results and Discussion” section of this preprint. A video demonstration of program, including downloading instructions is available at the link: https://www.youtube.com/watch?v=KN4uF3VfIeQ
Lipid Expansion Microscopy
Authors: White Brittany M , Conwell Amanda N , Wu Kane , Baskin Jeremy M
Published: April 2022

Strategies to visualize cellular membranes with light microscopy are restricted by the diffraction limit of light, which far exceeds the dimensions of lipid bilayers. Here, we describe a method for super-resolution imaging of metabolically labeled phospholipids within cellular membranes. Guided by the principles of expansion microscopy, we develop an approach featuring cell-permeable reagents that enables direct chemical anchoring of bioorthogonally labeled phospholipids into a hydrogel network and is capable of tunable, isotropic expansion, thus facilitating super-resolution imaging of cellular membranes. We apply this method, termed lipid expansion microscopy, to visualize organelle membranes with precision, including a unique class of membrane-bound structures known as nuclear invaginations. As it is compatible with standard confocal microscopes, lipid expansion microscopy will be widely applicable for super-resolution imaging of phospholipids and cellular membranes in numerous physiological contexts.

The study set out to affirm that Traditional Public Administration existed in pre-colonial Africa, specifically Nigeria. These pre-colonial administrative systems performed all the functions that are currently being executed by the modern public administrative systems, such as designing the best strategies for efficient delivery and the attainment of public goods. The case-study approach was adopted, in which old Oyo, Benin, Kanem Borno, and Oron Kingdom amongst others were comprehensively evaluated. This approach unveiled the structures and processes through which the aforementioned empires and Kingdoms were effectively governed. The focus of this paper was to identify and analyze the structure and processes, which amounted to public administration in these empires that performed the roles which are currently being performed by modern public administration. The findings revealed that old Oyo, Benin, Kanem Borno, and Oron Kingdom had standard processes for the implementation of what constituted public policies in these social entities. The successes of the administrative system accounted for the long duration of these pre-colonial states and in many cases, the colonial masters relied on them, for the administration of the territories they conquered. A case in point was the ‘indirect rule’ system in Nigeria and other West Africa States, which aided the continuation of the colonial administration. The role performance in the traditional system might have been fused, however, the functions of public administration were effectively carried out in these pre-colonial social entities. This exposition might have accounted for the long years of existence of these empires until internal contradictions, colonial conquests and rules resulted in their collapse. The study through the use of qualitative data affirmed the existence of traditional public administration in Africa and Nigeria in particular. This indeed was one of the notable ‘primitive gloriana’ (glory of the primitive past) of pre-colonial Africa and Nigeria in particular, that cannot be wished away by Eurocentric scholars.

In-Situ Stresses In Rock Masses: A General Review
Authors: Widarsono Bambang
Published: April 2022

The in situ state of stress is a rock's point-to-point property that must be taken into consideration in every subsurface engineering activity This has been realized to an increasing extent over the past 10 - 20 years. Good quality in situ stress information enhances the quality of engineering designs such ax for mining, petroleum and geothermal production. In turn good engineering designs will support the process of decision making in related industries. However, efforts are required to encourage the use and integration of this information into the engineering activities.This paper is basically a general review over the in situ stress that encompasses various aspects, among others are concept, causes/sources that generate it, influencing factors, the effect of scales, techniques for measuring it, and its distribution throughout the lithosphere. The review is supported by works and conclusions that have been made by various investigators in the past. The relative absence of the use of in situ stress information in petroleum engineering practices in Indonesia is also discussed. This includes the absence of demand upon the information, probable consequence, and the field cases that are likely caused by the absence.Apart from the importance of in situ stress information shown by the review, it has also prompted the need to apply proper use of in situ stress information in relation to the corresponding engineering scales. Inappropriate measurement techniques assigned to an engineering problem, which corresponds to a certain scale, will certainly lead to a serious misprediction over the expected outcome. These all are hoped to provide operators in the industry a complete general view over the in situ stresses their importance.

Effects of iron fertilization on plant growth, yield components and quality traits of industrial tomatoes
Authors: TURHAN Ahmet , ÖZMEN Neşe
Published: April 2022

This study was conducted in order to investigate the effects of different iron applications on the yield and fruit quality traits of industrial tomatoes. Experiments were conducted in a randomized block design with three replications under field conditions. The H-5803 and Delfo hybrid industrial tomato cultivars were used as the plant material and experimental treatments included 0 (control), 1.0, 2.0, 3.0, 4.0 kg ha-1 FeEDDHA (6% Fe) applications. The greatest increases in plant growth parameters (fruit length and width), marketable and paste yields were achieved with 2.0 and 3.0 kg ha-1 FeEDDHA. Iron treatments had significant effects on fruit weight, width, and lengths, and the greatest values were obtained from 2.0 and 3.0 kg ha-1. Increasing iron treatments also increased fruit quality traits (dry matter, soluble solids, total acidity). A significant relationship, however, was not observed between iron treatments and fruit pH values. In terms of plant nutrition, fertilizer cost, and yield increases, 2.0 kg ha-1 FeEDDHA treatment could be recommended as a useful fertilization strategy in tomato cultivation.
The effects of drought, salt and combined stresses on ion exchanges of eggplant (Solanum melongena L.) seedlings
Authors: KIRAN Sevinç
Published: April 2022

In this study, ion exchanges in eggplant plants exposed to drought, salt, and combined stress were researched. While drought-stressed plants were irrigated at 60% FC, salt-stressed plants were irrigated with water containing 50 mM sodium chloride (NaCl). Plants under combined stress were irrigated with water containing 50 mM sodium chloride (NaCl) at 60% FC. The plants remained under stress conditions for 90 days, after which they were harvested and evaluated for their ion content. Ca2+, K+ and Mg2+ contents in the shoot and root decreased significantly under drought, salt, and combined stresses. The most severe losses were detected in plants grown under combined stress. However, while Na accumulations increased under stress, these increases were more pronounced in the root under combined stress. K+/Na+ and Ca2+/Na+ ratios in the shoot and root under salt and combined stress were found to be lower than those under drought stress. In all stress conditions, especially K+/Na+ and Ca2+/Na+ ratios in the root showed significant decreases compared to the control. These findings showed that when drought and salt stress conditions were separately applied, Ca2+, K+ and Mg2+ accumulations in the shoot were less. On the other hand, the combination of drought and salt increased the ion losses in each stress factor more.
Comparison of spinach cultivation in floating hydroponic system and soil in glasshouse and open field conditions
Authors: BOSTANCI Kutluk Bilge , ÜLGER Salih
Published: April 2022

The objective of this study was to investigate the effect of glasshouse and outdoor conditions on the growth of spinach plants in floating hydroponic culture and soil. In the floating hydroponic culture, the plants were grown in a plastic tank (120x50x30 cm) and a volume of 80 L in a glasshouse and open field. Each seed was inserted at 13x5 cm in rock wool in styrofoam and then placed in the nutrient solution. There was no significant change in EC values measured in the glasshouse and outside, and the pH of the solutions in the outdoor environment was higher (except in late December) than those in the glasshouse. The earliest and late harvests were made in floating hydroponic culture in the glasshouse and outdoor cultivation at 64 and 97 days, respectively. The highest yield was 1.54 kg m-2 in open field cultivation, it was followed by 1.45 kg m-2 in the greenhouse and 1.32 kg m-2 in the open field in floating hydroponic culture, respectively. Despite the high yield that can be obtained from floating hydroponic culture cultivation in the glasshouse and outside, the fact that there is a lower marketable amount is a negative aspect. However, the floating hydroponic culture could be preferred to soil cultivation due to many advantages such as production 2-3 times a year, low labor costs, and less pesticide use. Spinach cultivation in the open field does not have any problems in terms of nitrate, but nitrate accumulation can be a problem in hydroponic culture.

Published: April 2022

Indonesian oil reserves and production are greatly influenced by investment. The focus of the study is to evaluate governance options to boost investment through appropriate fiscal regime and non-fiscal policies. The main aspect of the fiscal regime to increase investment is cost recovery. When cost recovery is still interpreted as a burden on state finances and there is still a stigma that contractors commit fraud in cost recovery, it is then a big challenge for oil and gas contractors to maximize investment and for regulator in giving approval on budget. Flexible Split and First Trance Petroleum (FTP) are the 2nd highest priority to improve to accommodate dynamic situation on the oil industry such as oil price fluctuation and size of reserves. Incentives and windfall profit treatment are the other key issues on fiscal. Sufficient geological surveys and researches are crucial things to attract investment. The duration of a contract that is only 30 years is too short to maximize the contractors return because of lengthy period for exploration, construction and drillings prior production. Combination of NOC dominated and Separation of Power model seems to be the best governance model. Partnership between Pertamina and multi-national company will facilitate investment funding.

The body weight of the species showed a significant positive correlation with crook of wings (r = 0.4, p = 0.002). This was probably an adaptation for sustained flight. Total body length also showed a significant positive correlation with length of tarsus (r = 0.3, p = 0.004). This might also be an adaptation for flight and fast running.

In this study, we investigate several published methods derived from Kozeny’s equation for permeability evaluation of the Lower Cretaceous marly chalk formations in the Danish North Sea. Using core measurements and well-logging data, we evaluate and compare controlling parameters for permeability calculation from spectral gamma ray, electrical resistivity, nuclear magnetic resonance, and sonic velocity logs. We provide a practical approach for modeling permeability at the well-log scale. We provide the obtained parameters for best fit according to each method for permeability modeling of clay-rich carbonate in the Danish North Sea Valdemar area.

Since gas hydrates are unconventional reservoirs, they pose unique challenges for identification, characterization, quantification, and extraction. The conventional approach—elastic logs—can provide a better method for identification through attribute analysis. On the other hand, geomechanical studies for wellbore stability analysis pave the way for the effective exploitation of gas hydrates. It is crucial to predict elastic logs against gas-hydrate-bearing sediments, which requires an effective rock physics model. In the present work, a study pertaining to the National Gas Hydrate Program-02 (NGHP-02) campaign in the Krishna‐Godavari (KG) Offshore Basin, India, where gas hydrates are deposited primarily in two facies—a shale-dominated shallower one and a sand-dominated deeper one that has been identified by responses of conventional and spectroscopy logs—is discussed. It is commonly known that depositional heterogeneity impacts petrophysical and elastic properties. To address this issue, an innovative approach has been adopted to model compressional and shear log data using rock physics modeling of gas hydrate reservoirs based on the depositional type of gas hydrate. Guidance from the change of compressional velocity data from log and core with an increase of gas hydrate saturation shows gas hydrate deposition in the study area can be explained through a matrix/grain-supported model. The Jason grain-supported rock physics model appeared best suited among different available rock physics models, depending on the clay volume and porosity in our study area. Using input from a robust multimineral petrophysical evaluation and rock physics modeling, the finalized model is propagated to test wells for predicting compressional, shear, and density logs, with the predicted data validated by core-measured compressional and shear data. Model consistency is indicated by a high correlation from multiwell crossplots of modeled and recorded elastic logs (compressional and shear velocity) with acoustic impedance. The developed rock physics model better discriminates gas hydrate in the shaly sand layer and gas hydrate in the sand-dominated layer, calcite, and shale in the VpVs domain.
