Authors: Assuah Charles Kojo , Mensah‒Wonkyi Thomas , Adusei Matilda Sarpong , Abedu Grace , Ghunney Stephen
Published: July 2022

This study illustrates the teaching strategies that undergraduate mathematics lecturers might employ to improve their students' conceptual knowledge of the confidence interval for the population mean. The study employed an action research method. It allowed the researcher to deepen his knowledge of the subject matter by planning, acting, evaluating, refining, and learning from this experience (Koshy, 2010). The participants consisted of sixty (60) level 200 mathematics students, who were randomly selected from a cohort of mathematics students from a mid-sized university in Ghana. The students completed the tasks assigned to them in their various groups by working collaboratively together, with their lecturer helping the process. They determined the particular theorem to apply in any given situation and applied the confidence interval formula to calculate the confidence intervals. The results indicated that collaborative learning, combined with effective instructional methods, improves students' conceptual knowledge of the confidence interval. An implication of this study is that students’ prior experiences act as a catalyst to enhance their conceptual knowledge. Thus, students who have a conceptual grasp of sampling techniques can conceptualise confidence intervals with ease. The study concludes that students should thoroughly understand the definitions and theorems relating to a statistical concept before they examine concrete examples relating to confidence intervals.

Based on the findings of the study, recommendations were made and these include; chemistry teachers should modify the behavior of their students for optimal performance and teachers should treat all the students equally regardless of their gender.
Morphological and Molecular Characterization of Cocoyam (Colocasia esculentum and Xanthosoma sagittifolium) (L) Schott germplasm from Nigeria using Simple Sequence Repeat-SSR marker
Authors: Nya Elijah , Okorie Nelson , Inyang Joseph , Uyoh Edak
Published: July 2022

Colocasia esculentum (L) Schott and Xanthosoma sagittifolium (L) Schott, commonly called cocoyam is one of the orphan crops with great potentials, but neglected by researchers and growers despite their high demands by consumers in recent times. Consequently, some of the local varieties have become almost extinct; this calls for the need to revive interest in these crops. This study was undertaken to characterize six cocoyam accessions collected from Cross River and Akwa Ibom States, Nigeria, using 13 qualitative and 6 quantitative Agro-morphological descriptors as well as simple sequence repeat (SSR) primers. The crops were laid out in a field using the Randomized Complete Block Design (RCBD) in 4 replications. Analysis of variance (ANOVA) test showed that the 6 accessions were not significantly different (P>0.05) in crop span, crop height, number of leaves, leaf width and leaf length. This indicates that these features cannot be used to distinguish between Colocasia and Xanthosoma spp. The qualitative traits were more useful in distinguishing between the two cocoyam species. Three of the primers used for molecular studies successfully amplified a few of the cocoyam accessions, indicating their suitability for genetic diversity studies in Colocasia esculenta and Xanthosoma spp.

Published: July 2022

The Covid-19 pandemic has tremendous implications for democracy worldwide. Emergency measures undertaken to combat the pandemic tend to demonstrate a trade-off between public health and fundamental democratic principles. The Caribbean is not immune from this. This paper examines how Covid-19, and the calling of a snap election in Barbados scheduled for January 19, 2022, when combined with archaic election rules, led to serious implications for the conduct of the election, specifically regarding the ability of citizens to vote. The paper is divided into five sections, beginning with an introductory section. The second section examines the implications of Covid-19 for democratic participation. The third section explores the legal framework for the conduct of elections in Barbados and the limitations of that legal framework. The penultimate section discusses the implications of the snap election for electoral participation and electoral integrity. The paper ends on the need for electoral reform in the country.

Authors: HALİLZADE Mohammad İbrahim , HALİLZADE İnci , KAYIKÇIOĞLU Fulya , KOÇ Sevgi
Published: July 2022

ABSTRACT

Objective: The aim of our study is to compare the clinical data and colposcopy- directed biopsy (CDB) results of atypical squamous cell of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL) cytology among high risk human papilloma virus (hrHPV) positive women.

Materials and Methods: A total of 359 hrHPV-positive patients with ASC-US and LSIL cytology, between 20-67 years of age were included in the study. Participants’ age, education status, smoking status, colposcopy results, and number of CDBs were assessed and clinical data compared with histopathologic evaluation of biopsies statistically.

Results: There were no statistically significant differences in terms of age, marital status, education status and smoking status of hrHPV + ASC-US and hrHPV + LSIL groups. Both groups were compared in terms of histopathologic results of CDBs and no statistically significant difference was observed between the groups. The number of CDB material and frequency of endocervical curettage were significantly higher in hrHPV + LSIL than hrHPV + ASC-US patients. There was no statistically significant difference between the two groups in terms of advanced treatment need. Control cytology performed during follow-up of both ASC-US and LSIL groups were resulted as benign.

Conclusion: The approach to ASCUS and LSIL is similarly important in HPV positivity. Since our follow up period includes a sort period of 1 year, further studies need to be carried out in order to demonstrate longer term outcomes.

Az emberi méltóság a rendőrséget is érintő válságkommunikációban
Authors: Pokrócos György
Published: July 2022

Aim: When writing this article, my aim was to show how the communication of events of public interest affects the police and the media.Methodology: In my writing I have compiled the relevant rules and, by way of example, compared the communication in accordance with Hungarian law to the reporting of world-wide events that did not take place in accordance with these rules.Findings: Police communication, which is often a crisis communication, usually provides information on cases that fall within its remit. If the publication of police camera footage becomes available, a rule must be kept in mind: human dignity is inviolable and the self-serving and offensive presentation of humiliating, vulnerable people in media content is prohibited.Value: As long as the Hungarian police do not wear a body camera and their recordings are not published, there is no need to fear an offense. Writings on the police website that mock the victims and are otherwise detrimental not only destroy the authority of the police. They are also liable to violate the human dignity of those concerned. In the future, I will continue to monitor and analyze announcements and news that violate human dignity.
The Galactic Distribution of Phosphorus: A Survey of 163 Disk and Halo Stars*

Published: July 2022

Phosphorus (P) is a critical element for life on Earth, yet the cosmic production sites of P are relatively uncertain. To understand how P has evolved in the solar neighborhood, we measured abundances for 163 FGK stars over a range of –1.09 < [Fe/H] < 0.47 using observations from the Habitable-zone Planet Finder instrument on the Hobby–Eberly Telescope. Atmospheric parameters were calculated by fitting a combination of astrometry, photometry, and Fe I line equivalent widths. Phosphorus abundances were measured by matching synthetic spectra to a P I feature at 10529.52 Å. Our [P/Fe] ratios show that chemical evolution models generally underpredict P over the observed metallicity range. Additionally, we find that the [P/Fe] differs by ∼0.1 dex between thin disk and thick disk stars that were identified with kinematics. The P abundances were compared with α-elements, iron-peak, odd-Z, and s-process elements, and we found that the evolution of P in the disk most strongly resembles that of the α-elements. We also find that molar P/C and N/C ratios for our sample match the scatter seen from other abundance studies. Finally, we measure a [P/Fe] = 0.09 ± 0.1 ratio in one low-α halo star and probable Gaia–Sausage–Enceladus member, an abundance ratio ∼0.3–0.5 dex lower than the other Milky Way disk and halo stars at similar metallicities. Overall, we find that P is likely most significantly produced by massive stars in core-collapse supernovae, based on the largest P abundance survey to date.
Models of Millimeter and Radio Emission from Interacting Supernovae

Published: July 2022

This work utilizes established models of synchrotron-powered light curves for core-collapse supernovae in dense circumstellar environments, namely, type IIn and Ibn, to demonstrate the potential for detecting millimeter emission from these events. The progenitor types of these supernovae are still an open question, but using the synchrotron light curves as probes for the circumstellar environments could shed light on the mass-loss histories of the progenitors and discern between different theories. Observations in millimeter bands are particularly fruitful, as they probe regions at smaller radii and higher ambient densities, where centimeter emission tends to be self-absorbed. In our application of these light curves, we explore a diversity of progenitor types and mass-loss profiles to understand their effects on the light-curve shapes. Additionally, we fit model parameters to the 8 GHz light curve of type IIn supernova 2006jd and then create millimeter light curves using these parameters to show the possibility of detecting an early millimeter peak from such an event. We predict that next generation millimeter surveys will possess the capability to detect nearby and extreme events. However, there is a pressing need for millimeter follow-up of optically discovered interacting supernovae to more completely sample the true population.
Polarized Optical Emission of the Blazar PKS 1222+216: Discovery of a 420 day Quasiperiodic Signal
Authors: Zhang Pengfei , Wang Zhongxiang
Published: July 2022

We report our search for quasiperiodic signals in long-term optical and γ-ray data for the blazar PKS 1222+216, where the data are from the Steward Observatory blazar monitoring program and the all-sky survey with the Large Area Telescope on board the Fermi Gamma-ray Space Telescope, respectively. A quasiperiodic signal, with a period of ≃420 days and a significance of >5σ, is found in the measurements of the optical linear polarization degree for the source, while no similar signals are found in the optical and γ-ray light curves covering approximately the same time period of ∼10 yr. We study the quasiperiodic variations by applying a helical jet model and find that the model can provide a good explanation. This work shows that polarimetry can be a powerful tool for revealing the physical properties, in particular the configuration of the magnetic fields of jets from galactic supermassive black holes.

Published: July 2022

New instruments sensitive to chromospheric radiation at X-ray, UV, visible, IR, and submillimeter wavelengths have become available that significantly enhance our ability to understand the bidirectional flow of energy through the chromosphere. We describe the calibration, coalignment, initial results, and public release of a new data set combining a large number of these instruments to obtain multiwavelength photospheric, chromospheric, and coronal observations capable of improving our understanding of the connectivity between the photosphere and the corona via transient brightenings and wave signatures. The observations center on a bipolar region of enhanced-network magnetic flux near disk center on SOL2017-03-17T14:00–17:00. The comprehensive data set provides one of the most complete views to date of chromospheric activity related to small-scale brightenings in the corona and chromosphere. Our initial analysis shows a strong spatial correspondence between the areas of broadest width of the hydrogen-α spectral line and the hottest temperatures observed in Atacama Large Millimeter/submillimeter Array (ALMA) Band 3 radio data, with a linear coefficient of 6.12 × 10−5Å/K. The correspondence persists for the duration of cotemporal observations (≈60 m). Numerous transient brightenings were observed in multiple data series. We highlight a single, well-observed transient brightening in a set of thin filamentary features with a duration of 20 minutes. The timing of the peak intensity transitions from the cooler (ALMA, 7000 K) to the hotter (XRT, 3 MK) data series.
The Behavior of HgMn Stars in the Far UV-Paper 8: HR 7775
Authors: Monier Richard
Published: July 2022

The analysis of 14 high resolution spectra of the chemically peculiar star HR 7775 recorded by the International Ultraviolet Explorer reveals large amplitude variations of the far and mid-ultraviolet flux (at minimum the flux is about 70% of its value at maximum) over the various observations with IUE. The lines at minimum flux are redshifted respect to their positions at maximum. These variations probably reflects an eclipse by a cooler and smaller companion of spectral type A or even early F. The absence of TESS observations prevents a search for periodic orbital and rotational variabilities.

Searching for Binary Asteroids in Pan-STARRS1 Archival Images
Authors: Ou James , Baranec Christoph , Bus Schelte J.
Published: July 2022

We developed two different point-spread function (PSF) analysis techniques for discovering wide separation binary asteroids in wide-field surveys. We then applied these techniques to images of main belt asteroids in the 4–60 km size range captured by Pan-STARRS1. Johnston lists fewer than 10 known binaries in this size range with separations greater than 10% of the primary’s Hill radius, so discovering more wide binary asteroids is crucial for understanding the limits of binary stability and improving our knowledge of asteroid masses. We analyzed each image by (i) comparing the major axis orientation of the asteroid’s elliptical PSF to its nonsidereal rate on the sky and (ii) comparing the one-dimensional median profile created by collapsing the image along the asteroid’s direction of motion to that of nearby field stars. For both methods, we flagged any results that deviated significantly from the expected measurements of single asteroids, and those targets with the most flags were identified as binary candidates for confirmation with high-acuity imaging.
The Effects of Methane Clathrates on the Thermal and Seismic Profile of Titan's Icy Lithosphere
Authors: Marusiak Angela G. , Vance Steven , Panning Mark P. , Bryant Andrea S. , Hesse Marc A. , Carnahan Evan , Journaux Baptiste
Published: July 2022

We investigate the effects of methane clathrates on Titan’s thermal and seismic structure. The Dragonfly mission is planned to arrive at Titan in 2033 with a payload that includes a seismic package. The seismic instruments are tasked with recording seismic events and recovering the internal structure. Here, we explore whether differences in thermal and seismic profiles between a pure water ice shell and an ice shell with a clathrate lid could be detectable with seismic instrumentation. Due to their lower thermal conductivity, clathrates reduce the conductive lid thickness thus altering the thermal profile. The differences between seismic velocities of clathrates and pure water ice, coupled with changes in the thermal profile, indicate the clathrate lid will create lower seismic velocities, particularly for the upper 10 km of the surface ice shell. The differences in P and S velocity at the surface are 2.9% and 4.5%, respectively, and reach up to 8.4% (for both P and S) at a depth of 9.6 km. Due to changes in thermal profile, the seismic attenuation of the ice shell will change such that clathrates will suppress surface wave amplitudes relative to the pure water ice model. The clathrate lid will further create minor changes (≤2.0%) in the surface wave dispersion curves. Dragonfly, or other future seismic investigations, could provide evidence for or against the presence of a clathrate lid by constraining the thermal and seismic profile of Titan’s ice shell, by measuring the relative amplitudes of the surface to body waves, or by constraining the surface wave dispersion with high accuracy and precision.
Exploring Jupiter's Polar Deformation Lengths with High-resolution
Shallow Water Modeling
Authors: Hyder Ali , Lyra Wladimir , Chanover Nancy , Morales-Juberías Raúl , Jackiewicz Jason
Published: July 2022

The polar regions of Jupiter host a myriad of dynamically interesting phenomena,
including vortex configurations, folded-filamentary regions (FFRs), and chaotic
flows. Juno observations have provided unprecedented views of the high
latitudes, allowing for more constraints to be placed upon the troposphere and
the overall atmospheric energy cycle. Moist convective events are believed to be
the primary drivers of energetic storm behavior as observed on the planet. Here
we introduce a novel single-layer shallow water model to investigate the effects
of polar moist convective events at high resolution, the presence of dynamical
instabilities over long timescales, and the emergence of FFRs at high latitudes.
We use a flexible, highly parallelizable, finite difference hydrodynamic code to
explore the parameter space set up by previous models. We study the long-term
effects of deformation length (L

d
), injected pulse size, and injected geopotential. We find that models
with L

d
beyond 1500 km (planetary Burger number, Bu = 4.4 × 10−4) tend
to homogenize their potential vorticity in the form of dominant stable polar
cyclones, while lower-L

d
cases tend to show less stability with regard to Arnol’d-type flows. We
also find that large turbulent forcing scales consistently lead to the formation
of high-latitude FFRs. Our findings support the idea that moist convection
occurring at high latitudes may be sufficient to produce the dynamical variety
seen at the Jovian poles. Additionally, derived values of localized horizontal
shear and L

d
may constrain FFR formation and evolution.
Le remède dans les mots. Platon et la pharmacopée littéraire du Moyen Âge
Authors: Clamote Carreto Carlos F.
Published: July 2022

Creusant le clivage entre mythos et logos , la conception platonicienne de l’écriture comme pharmacopée a durablement influencé la pensée occidentale, demeurant particulièrement prégnante au Moyen Âge, surtout à partir du xii e  siècle, à une époque où la voix perd progressivement son lien épistémique à la Présence et à la Vérité au profit d’une conception du savoir et du pouvoir de plus en plus médiatisée par une dynamique scripturaire. Un bref parcours à travers Les Miracles de la Sainte-Vierge (Gautier de Coincy) et Les Évangiles des quenouilles nous permettra de mieux saisir cette logique de la dualité intrinsèquement liée à la logographie comme remède et poison.

Segredos e medicinas em Goa colonial durante o século XIX
Authors: Roque Ricardo
Published: July 2022

L’auteur se penche sur l’histoire de la recherche médicale sur les savoirs et les médicaments indiens, désignés comme des « secrets », dans la Goa coloniale. Le texte porte sur les pratiques et les programmes de traduction scientifique de « secrets » prônés par les médecins du Service de Santé associés à l’École Médicale de Goa, entre 1840 et 1930. Les médecins au service de l’État colonial ont investi dans la chasse aux médecines indiennes, afin d’affirmer leur autorité professionnelle. Dans le même temps cependant, ils se montrèrent fascinés et intrigués par les capacités des pratiques thérapeutiques de ces supposés guérisseurs, pendant plusieurs décades, et déployèrent leurs efforts pour s’approprier les pouvoirs occultes des savoirs vernaculaires indiens.
On moment convergence for some order statistics
Authors: Wang Jin-liang , Deng Chang-shou , Li Jiang-feng
Published: July 2022

By exploring the uniform integrability of a sequence of some order statistics (OSs), we obtain the moment convergence conclusion of the sequence under some weak conditions even when the corresponding population of interest has no moment of any positive order. As an application, we embody the range of applications of a theorem presented in a reference dealing with the approximation of the difference between the moment of a sequence of normalized OSs and the corresponding moment of a standard normal distribution. By the aid of the embodied theorem, we explore the infinitesimal type of the moments of errors when we estimate some population quantiles by relative OSs. Finally, by the obtained conclusion, we can easily get a combination formula which seems hard to be proved in other methods.

The paper analyzes the problems that conventions may encounter as an instrument of harmonization of international trade law. These problems are correlated with the possibility of different interpretations of the text by the courts of different states, or with different ways of filling legal gaps that exist in their text. They are particularly significant in a situation where there is no supreme interpreter of the text, and may lead to a failure of the harmonization project altogether. The UN Convention on the International Sale of Goods is one of the most successful instruments of harmonization. Because of that, we will try to understand how its rules on interpreting (of the text) and filling legal gaps (in the text) have led to its acceptance by both developed and developing countries, civil and common law traditions, as well as the countries of the former socialist bloc, and what can be learned from this when drafting new instruments of harmonization.

Važnost ovog Zbornika ponajviše se ističe u jasnom naglašavanju panoramske širine, umijeća i snage oblikovanja znanstvenog i intelektualnog interesa i doprinosa profesora Nikole Viskovića. Zajednički nazivnik svih priloga u knjizi jest poruka da povijest nomosa kao temeljne preokupacije teoretičara prava nije zanimljiva sama po sebi, već je ona prije svega važna zbog nemjerljivog značenja za razvoj i društveni utjecaj pravne i političke teorije do današnjih dana. Vješto razvijajući širok raspon intelektualnog interesa kroz različita područja prava, politike i kulture, Viskovićev élan vital rezultirao je produkcijom koja je, uspinjući se s plana pravne teorije na druge životne intelektualne, političke, kulturne, ekološke i druge teme i planove, uspješno razotkrivala – i još uvijek to čini – sva važna stanja, probleme, aktere i pravce suvremenog pravnog diskursa. Zalažući se prije svega za ozbiljno kritičko preispitivanje postojećeg državnopravnog poretka, u kojoj kritici njegovo integralno poimanje prava (svaka je pravna pojava spoj društvenih odnosa, vrijednosti i normi) natkriljuje svaki njegov redukcionizam, profesor Nikola Visković pojavljuje se i ostaje uporni, konstruktivni i dostojni akter one duge i bogate intelektualne tradicije koja u analizi stalnih i otvorenih tenzija između “činjenica i normi” (Faktizität und Geltung) neumorno i nezaustavljivo propituje i traži humani i časni smisao prava i politike.
The Serial Will Be Televised: Serial Television’s Revolutionary Potential for Multidisciplinary Analysis of Social Identity - Reviews of Birth of the Binge: Serial TV and the End of Leisure by Dennis Broe, Wayne State University Press, 2019, and Gender and Seriality: Practices and Politics of Contemporary US Television by Maria Sulimma, Edinburgh University Press, 2021

This review examines how two recent books use a multidisciplinary approach to examine seriality as both technology and narrative mode in contemporary American television. Both Dennis Broe’s Birth of the Binge: Serial TV and the End of Leisure (Wayne State University Press, 2019) and Maria Sulimma’s Gender and Seriality: Practices and Politics of Contemporary US Television (Edinburgh University Press, 2020) examine the impacts of the interactivity between socio-political climates and the unique formal aspects of serial television has on social identity, relationality, and the potential for resistance within the medium.
The History of the American Comic Book, Revised - Review of Comic Books Incorporated: How the Business of Comics Became the Business of Hollywood by Shawna Kidman, University of California Press, 2019
Authors: Guthertz Asher
Published: July 2022

This book review of Shawna Kidman’s Comic Books Incorporated: How the Business of Comics Became the Business of Hollywood highlights the works crucial intervention in comic book studies. In the face of a rote history of the comic book as a persistent subcultural phenomenon, Kidman argues that attending to the various legal, social, and industrial infrastructures of comic book culture can illustrate the ebbs and flows of comic book popularity, its shifts in genres and tone, and its movements across mediums as the path of a “fundamentally corporate” medium, “a dominant form in a culture built to support its growth.” The review sketches the book’s chapters, which each focus on a different form of infrastructure relevant to the history of the comic book: distribution, copyright law, subculture, and financing. I end with further areas of research suggested by this work, particularly within the field of historical ethnography. While Comic Books Incorporated tells its story through the history of industrial logics, a closer attention to comic book reading practices during the time in which this story takes place can deepen our understanding of the transformation from a mass medium with seemingly equal readership across gender to a niche subcultural fascination for college aged white men.Throughout the text, the work demystifies a prevailing narrative that the comics industry and fanbase tells: that the success of the medium is due to the inherent quality of the source material. This book thoroughly demonstrates that the evolution of the comic book was driven not by creativity and iconoclasm, but by corporate logic.

A blanket fertilizer was recommended by the Department of Agriculture (DOA) for all species of cabbage. However, the fertilizer application is needed to be site-specific. Hence a field experiment was conducted at Ambalangoda during the Maha season in 2019 with the objective of evaluating the effect of Calcium (Ca), Magnesium (Mg) and Boron (B) on the yield and the Quality of cauliflower. Batapola Ambalangoda soil was analyzed for available nutrients and identified the most deficit macronutrients as Ca, B and Mg. This was laid out in a Randomized Complete Block Design with four replicates. One plot size was 1m × 2m and each plot had ten plants. Five treatments were taken as NPK (DOA recommendation) (T1), NPK + Ca + Mg (T2), NPK + Ca + Mg + B (T3), NPK + Ca (T4), NPK + Mg (T5). Incorporating magnesium, calcium and boron with the DOA recommendation resulted in larger cauliflower curds under field conditions, contributing to a 44.2 % increase in curd yield. The additional four days of shelf life were observed in the curds of T3.

Calotropis gigantea (L.) R.Br. (Asclepiadaceae) is a perennial herb used as a traditional medicine. This is an important plant however, presently under the threat of extinction. While the entire plant is used for skin diseases, powdered root bark able to cure elephantiasis, dysentery and leprosy. The stem bark is important for gastrointestinal and respiratory track diseases including dysentery, spleen complaints, ringworm and pneumonia. The toothache, caries, leprosy, stings, syphilis, rheumatism and tumors were treated using latex of the plant. Powdered flowers have therapeutic value for coughs, colds, and asthma. The leaf extraction has potential to heal burns and relief headaches, rheumatic pains. Mosquito repellent efficacy of flower extracts was already published. In addition, because of the massive forest destruction, it has been included in the Red Data Book of IUCN. This paper will discuss the significance of this species and the medicinal value to convince the importance of conservation by reintroducing regenerated plants into their natural habitats.

Aloe vera is the plant belongs to family Liliaceae. Aloe vera has acquired great commercial importance globally. In Aloe vera, researches clearly show that organic manures are more efficient compared to chemical fertilizers. This study investigated the growth and yield of Aloe vera in response to different organic fertilizers or manures. This research was laid out in Randomized Complete Block Design (RCBD) in the Crop Farm, Eastern University of Sri Lanka, as a polybag experiment with five treatments and four replicates from November 2019 to March 2020. The treatments are T1 (Control), T2 (Compost), T3 (Cow dung), T4 (Commercially available organic liquid fertilizer) and T5 (Jeewamirta). In almost all the growth and yield parameters showed a significant increase by compost (T2) and cow dung (T3) treatments compared to other treatments. In those significant parameters, between compost (T2) and cow dung (T3) treatments were shown non-significance in total leaf skin weight, total root fresh weight and leaf skin weight of largest leaf. Therefore, considering the growth parameters, yield parameters, and especially economic important parameter (gel dry weight) compost and cow dung could be recommended to enhance the growth and yield in the cultivation of Aloe barbadensis.

The aim of this study was to assess the impact of natural rubber tire waste charcoal (NRTWC) amendment on carbon mineralization in tea cultivated soils in low country wet zone of Sri Lanka. NRTWC was applied at different rates (0%, 1%, 1.6%, 2.2% and 2.8% w/w) and carbon mineralization in soil was evaluated at 10 and 20 weeks after the treatment. Representative samples were incubated for 42 days and microbial respiration was determined. During the first seven days of incubation, a rapid carbon mineralization was observed for all the treatments. A rapid decline of carbon mineralization was then observed during the period from 14th to 28th day of incubation. No changes were observed towards the end of the incubation (35 to 42 days). Significant (P ≤ 0.05) differences among the different rates of NRTWC application were noticed during the initial stages of the incubation. However, the variations were minimal after 14th day of the incubation. The cumulative carbon mineralization ranged from 506 to 1072 mg/kg soil for the samples taken at 10 weeks after treatment. The corresponding variation changed from 506 to 1730 mg/kg soil for the samples drawn at 20 weeks after treatment. The cumulative soil carbon mineralization increased rapidly during the early stages, then decreased gradually and finally flattened out towards the end of the incubation. The application of NRTWC resulted in a substantial increase in cumulative carbon mineralization when compared with the control. As revealed by the results, NRTWC decomposes slowly and can be considered as a sound source of soil amendment which could enhance soil carbon sequestration in degraded tea soils.

Caspase-8 (Casp8) suppresses receptor-interacting protein kinase-3 (RIPK3)/mixed lineage kinase domain-like protein (MLKL)-dependent necroptosis, demonstrated by the genetic evidence that deletion of Ripk3 or Mlkl prevented embryonic lethality of Casp8-deficient mice. However, the detailed mechanisms by which Casp8 deficiency triggers necroptosis during embryonic development remain unclear. In this article, we show that Casp8 deletion caused formation of the RIPK1-RIPK3 necrosome in the yolk sac, leading to vascularization defects, prevented by MLKL and RIPK3 deficiency, or RIPK3 RHIM mutant (RIPK3 V448P), but not by the RIPK1 kinase-dead mutant (RIPK1 K45A). In addition, Ripk1K45A/K45ACasp8−/− mice died on embryonic day 14.5, which was delayed to embryonic day 17.5 by ablation of one allele in Ripk1 and was completely rescued by ablation of Mlkl. Our results revealed an in vivo role of RIPK3 RHIM and RIPK1K45A scaffold-mediated necroptosis in Casp8 deficiency embryonic development and suggested that the Casp8-deficient yolk sac might be implicated in identifying novel regulators as an in vivo necroptotic model.
