Development and Validation of Height-Diameter Models for Cupressus lusitanica in Gergeda Forest, Ethiopia

Abstract This study was conducted to fit and evaluate ten existing nonlinear height diameter functions for Cupressus lusitanica in Gergeda forest Ethiopia. A total of 260 trees were measured for their diameter at breast height (D) and height using destructive sampling methods. This data were randomly split in to two datasets for model development (50%) and for model validation (50%). Considering hetroscadasticity of variance, all functions were fitted using weighted nonlinear least square regression. To evaluate the performance of each model, five fit statistics-such as Coefficient of determination (R2), root mean square error (RMSE), bias (Ē), absolute mean deviation (AMD), and coefficient of variation (CV%) were used. Among all the models tested, the Weibull type function of the form H = 1.3 + a (1-exp (-bDc)) + ɛ was observed to give the best fit based on the model’s goodness of fit and predictive ability. Therefore, this model with three parameters has been conformed to provide reliable estimate of total tree height for Cupressus lusitanica in Gergeda forest, Ethiopia.
Correlation between Reversing of Multidrug Resistance and Inhibiting of [ 3 H ] Azidopine Photolabeling of P-Glycoprotein by Newly Synthesized Dihydropyridine Analogues in a Human Cell Line 1

Ten synthetic dihydropyridine analogues were investigated for their ability to reverse drug resistance in a multidrug-resistant human carci noma cell line, KB-C1. Four dihydropyridine analogues completely re versed the resistance, three lowered the resistance, and three had little effect. The radioactive photoactive dihydropyridine calcium channel blocker, |3H|azidopine, photolabels P-glycoprotein in membrane vesicles from KBCl cells. This photolabeling was almost completely inhibited by excess dihydropyridine analogues that reversed or lowered drug resistance. In contrast, the labeling was not significantly inhibited by analogues that do not reverse resistance. Among other reversing agents, cepharanthine and reserpine inhibited the (3H|azidopine photolabeling, but thioridazine did not. A'-Solanesyl-/V,Ar'-bis(3,4-dimethoxybenzyl)ethylenediamine slightly inhibited the labeling at 100 Â¿IM. An anticancer agent, vinblastine, also inhibited the labeling. The correlation between the reversing of the drug resistance and the inhibition of the [3H]azidopine photolabeling of P-glycoprotein by dihy dropyridine analogues suggests a role for P-glycoprotein in multidrug resistance and also the reversing of the resistance by dihydropyridine analogues.
Effects on Spacecraft Radiometric Data at Superior Solar Conjunction

During 2006, three ESA interplanetary spacecraft, Rosetta, Mars Express (MEX) and Venus Express (VEX), passed through superior solar conjunction. For all three spacecraft, the noise in the post-fit range-rate residuals from the orbit determination was analysed. At small Sun-Earth-Probe (SEP) angles the level was almost two orders of magnitude higher than normal. The main objective was to characterize the Doppler (rangerate) noise as a function of SEP angle. At least then the range-rate data can be appropriately weighted within the orbit determination so that the solution uncertainties are realistic. For VEX, some intervals of particularly noisy Doppler data could be correlated with unusual solar activity. For Rosetta, the biases in the range data residuals were analysed with the aim of improving the model used for calibrating the signal delay due to the solar plasma. The model, which originally had fixed coefficients, was adjusted to achieve better fits to the data. Even the relatively small Doppler biases were well represented. Using the improved model, the electron density at 20 solar radii was compared with earlier results obtained by radio science studies using Voyager 2 and Ulysses radiometric data. There is some evidence for a dependency of the density on the phase within the 11 years solar cycle.
Accelerated Defect Discovery and Reliability Improvement through Risk-Prioritized Testing for Web Applications

: In this paper, we present a risk-prioritized testing strategy aimed at accelerating defect discovery and reliability improvement for Web applications. This strategy is based on analyzing defect rate or density using Web logs and defect data from development activities to produce a prioritized list for testing. We empirically compare it against simulated coverage-based testing for five websites from diverse Web application domains, including academic, open source project, small business catalog showroom, large e-Commerce application, and social networking websites. The results from comparing their respective defect discovery profiles demonstrate the superiority of risk-prioritized testing in accelerating defect discovery and reliability improvement.
“The most important thing is to communicate with students”: experiences and voices of Canadian youth during the COVID-19 pandemic

ABSTRACT This study aimed to learn directly from youth about how they navigated and experienced the COVID-19 pandemic response, with a focus on secondary school policies and protocols. Thirty semi-structured one-on-one interviews were conducted with Canadian youth (13–18 years old, 53.3% girls, 46.7% white) and analysed using inductive interpretive description. Youth discussed challenges related to a lack of direct communication and consultation about pandemic-related decisions, the shifts between different school modalities, the loss of extracurricular opportunities, and a need for mental health support, which they connected to adverse impacts on their learning, health, and future opportunities. Participants’ top recommendation for adults was to include youth in decision-making on matters that impact them. To uphold their rights, support healthy development, and ensure more effective policies/protocols, the authentic engagement of youth in decision-making processes and improved communication are necessary and were absent during the pandemic.
Protocol for Treatment of Oral Verrucous Carcinoma - A Systematic Review and Meta-Analysis

Background: The objective of this study is to provide a structured protocol for the treatment of verrucous carcinoma (VC) based on size, bone invasion, recurrence and whether neck dissection is necessary or not. In addition, the study evaluates the probability of a wrong histopathological diagnosis. Data Sources: A search was conducted in the Cochrane Library, PubMed and Google from January 1962 to October 2022 by using MeSH terms and keywords. Studies reporting treatment modalities for VC and different histopathological diagnoses after excision of the lesion were selected except case reports and review articles. Study Eligibility Criteria: Thirteen articles were selected. Six hundred and thirty cases of VC were treated by surgery, surgery + neck dissection, radiotherapy, chemotherapy and combination therapy. Statistical analysis revealed surgical treatment as a preferred option. Despite being enlarged, the lymph node was negative for metastasis. So, in OVC cases neck dissection adds only unnecessary morbidity to patients. Participants and Interventions: Radiotherapy or chemotherapy can be used to downstage the disease. 23.3% of cases reported wrong histopathology diagnosis. Study Appraisal and Synthesis Methods: Patients treated for squamous cell carcinoma (SCC) will only experience unnecessary morbidity unless the correct diagnosis is made between VC and hybrid VC. Irrespective of size VC does not metastasise until there are no foci of SCC. Conclusions: Surgical excision of T1- and T2-sized lesions can be performed under local anaesthetic as a biopsy procedure. T3 or T4 lesion can be resected with a safe margin. If it comes as hybrid VC or VC with close margin (0.5 cm, <0.5 cm), neck dissection and further margin should be excised as a second procedure respectively.
A parametrically modulated dual-axis atomic spin gyroscope

We describe a dual-axis atomic spin gyroscope based on an alkali metal-noble gas comagnetometer. Alkali metal vapor is optically pumped, and then the noble gas is hyperpolarized along the z axis. When sensing a transverse rotation, the polarized noble gas will be induced to precess and produce an effective magnetic field in the x – y plane for alkali metals to precess under. Operating in the spin-exchange relaxation-free regime, alkali atoms are modulated by the z axis magnetic field and serve as an integrated in-situ dual-axis magnetometer to detect the gyroscopic precession in the x and y axes simultaneously, using a single probe beam. By using the parametric modulation technique, the low frequency drift is effectively suppressed and a bias instability of less than 0.05 deg/h has been achieved in our dual-axis atomic spin gyroscope.
Neurological Complications Secondary to Intimate Partner Violence: A Brief Review and Case of Posterior Cerebral Artery Cerebrovascular Accident Following Domestic Abuse

Intimate partner violence (IPV) is a growing public health concern, with millions of individuals experiencing IPV each year. Consequences of IPV include psychological disturbances, changes in physical health, and in extreme cases, severe disablement or death. Here, we describe a case of a patient who experienced IPV, leading to a variety of neurological symptoms, and was diagnosed with a posterior cerebral artery (PCA) cerebrovascular accident (CVA) 10 days later. While cases of traumatic brain injury leading to CVA, or stroke, have been documented, there is currently limited reported literature on the neurological complications, specifically stroke, secondary to IPV in adults. Due to this limited reporting, future studies on IPV will be needed to fully understand the long-term neurological complications that may occur.
The Influence of κ-Carrageenan-R-Phycoerythrin Hydrogel on In Vitro Wound Healing and Biological Function

Wound healing is widely recognized as a critical issue impacting the healthcare sector in numerous countries. The application of wound dressings multiple times in such instances can result in tissue damage, thereby increasing the complexity of wound healing. With the aim of tackling this necessity, in the present study, we have formulated a hydrogel using natural polysaccharide κ-carrageenan and phycobiliprotein R-phycoerythrin from Pyropia yezoensis. The formulated hydrogel κ-Carrageenan-R-Phycoerythrin (κ-CRG-R-PE) was analyzed for its antioxidant and antimicrobial activity. The wound healing potential of the κ-CRG-R-PE was evaluated in Hs27 cells by the wound scratch assay method. The hydrogel showed dose-dependent antioxidant activity and significant antimicrobial activity at 100 μg/mL concentration. κ-CRG-R-PE hydrogels promoted more rapid and complete wound closure than κ-Carrageenan (κ-CRG) hydrogel at 24 and 48 h. κ-CRG-R-PE hydrogels also filled the wound within 48 h of incubation, indicating that they positively affect fibroblast migration and wound healing.
Environmental Law and Policy

This chapter for the Handbook of Law and Economics provides an economic perspective of environmental law and policy. We examine the ends of environmental policy, that is, the setting of goals and targets, beginning with normative issues, notably the Kaldor-Hicks criterion and the related method of assessment known as benefit-cost analysis. We examine this analytical method in detail, including its theoretical foundations and empirical methods of estimation of compliance costs and environmental benefits. We review critiques of benefit-cost analysis, and examine alternative approaches to analyzing the goals of environmental policies. We examine the means of environmental policy, that is, the choice of specific policy instruments, beginning with an examination of potential criteria for assessing alternative instruments, with particular focus on cost-effectiveness. The theoretical foundations and experiential highlights of individual instruments are reviewed, including conventional, command-and-control mechanisms, market-based instruments, and liability rules. Three cross-cutting issues receive attention: uncertainty; technological change; and distributional considerations. We identify normative lessons in regard to design, implementation, and the identification of new applications, and we examine positive issues: the historical dominance of command-and-control; the prevalence in new proposals of tradeable permits allocated without charge; and the relatively recent increase in attention given to market-based instruments. We also examine the question of how environmental responsibility is and should be allocated among the various levels of government. We provide a positive review of the responsibilities of Federal, state, and local levels of government in the environmental realm, plus a normative assessment of this allocation of regulatory responsibility. We focus on three arguments that have been made for Federal environmental regulation: competition among political jurisdictions and the race to the bottom; transboundary environmental problems; and public choice and systematic bias.
Mod $p$ equivalence classes of linear recurrence sequences of degree~$2$

Laxton introduced a group structure on the set of equivalence classes of linear recurrence sequences of degree two. This result yields much information on the divisibilities of such sequences. In this paper, we introduce other equivalence relations for the set of linear recurrence sequences (Gn) which are defined by G0, G1 ∈ Z and Gn = TGn−1 − NGn−2 for fixed integers T and N = ±1. The relations are given by certain congruences modulo p for a fixed prime number p which are different from Laxton’s without modulo p equivalence relations. We determine the initial terms G0, G1 of all the representatives of the equivalence classes (Gn) satisfying p ∤ Gn for any integer n, and give the number of the equivalence classes. Furthermore, we determine the representatives of Laxton’s without modulo p classes from our modulo p classes.
QUALITATIVE ANALYSIS OF DRUG SUBSTANCES IN RHEUMATIC JAMU SAMPLES USING THIN LAYER CHROMATOGRAPHY

Since ancient times, jamu have been used to treat various diseases. Recently, the number of jamu has increasing and this has led several manufacturers to commit fraud. They added drug substances (DS) into jamu for gaining the effect of jamu so that can raise the sales of jamu in market . The addition of DS into herbal medicine is a violation of the regulation issued by The Ministry of Health. Such practices can cause side effects that are very dangerous for health. The purpose of this research is to analyze the presence of DS in jamu samples that are frequently consumed and circulated in Kranggan, Temanggung and Magelang city. Thin-Layer Chromatography (TLC) was employed to detect the presence of prednisone, paracetamol, and mefenamic acid. The working principle of the separation of compounds with TLC is to separate samples based on the partition difference between samples and the solvent used. In this case, the stationary phase used is the silica gel plate GF254 with the mobile phase for prednisone using ethyl acetate:chloroform (4:1), mefenamic acid using chloroform:methanol (9:1),and paracetamol using chloroform:ethanol (8:1). As a result of qualitative analysis, jamu samples in those areas do not contain any drug substances that were suspected to be present. Keywords: jamu, prednisone, paracetamol, mefenamic acid
Developing Skills in Intra-Workplace Rehabilitation Education: I

This study aimed to develop an educational model that integrates three elements: knowledge, skills, and attitudes—developing the educational model proposed in the previous Paper I—and to widely investigate and characterize previous learning-related models. The basic educational model proposed here is my seven-step process model of rehabilitation practice. Knowledge consists of four aspects: 1) clinical, 2) psychological, 3) environmental, and 4) disability; skills consist of two steps: 5) identifying intervention points and 6) setting feasible goals; and attitudes 7) of communicating and sharing policies and paths with patients, families, and other professionals. This constitutes the process of rehabilitation practice, and a framework that integrates the three elements is developed here. This study focuses on integrating knowledge, skills, and attitudes into what Bloom described as “the integration of instruction and assessment” so that learners and instructors can reconcile them. Therefore, a typology that explains each other for advancing and deepening individual skills is adopted. In Bloom’s original taxonomy of educational goals, the cognitive domain has five layers in the pyramid of knowledge; the psychomotor domain of Simpson’s has seven layers, and Bloom’s affective domain is represented by five in another pyramid. In addition, the above seven layers of the process model and the seven layers of the skill level of the Dreyfus model were brought together. The integration of the above five ty-pologies becomes a useful educational evaluation model when the relationships are clarified.
Semi-Supervised Learning for Spatio-Temporal Segmentation of Satellite Images

This thesis investigates the applicability of semi-supervised machine learning algorithms for forest land cover segmentation in satellite images. Instead of directly evaluating satellite imagery, the CityScape dataset is utilized for result verification and reproducibility. We review the semi-supervised machine learning algorithms, introduce MixMatch as a referencemethod and a novel algorithm based on symmetric learning of variational autoencoders, along with a self-contained introduction to variational autoencoders. The research aims to compare the segmentation potential and capabilities of both the new and the reference algorithms using a U-net network-based model architecture. The results show that MixMatch effectively enhances segmentation performance to supervised baseline, particularly in scenarios with limited labeled data. Although the symmetrical learning does not exceed the supervised baseline, the experiments still serve as a proof of concept, highlighting areas for further investigation.
Kv2.1 Channels Prevent Vasomotion and Safeguard Myogenic Reactivity in Rat Small Superior Cerebellar Arteries

Vascular smooth muscle voltage-gated potassium (Kv) channels have been proposed to contribute to myogenic autoregulation. Surprisingly, in initial experiments, we observed that the Kv2 channel inhibitor stromatoxin induced vasomotion without affecting myogenic tone. Thus, we tested the hypothesis that Kv2 channels contribute to myogenic autoregulation by fine-tuning the myogenic response. Expression of Kv2 channel mRNA was determined using real-time PCR and ‘multiplex’ single-cell RT-PCR. Potassium currents were measured using the patch-clamp technique. Contractile responses of intact arteries were studied using isobaric myography. Expression of Kv2.1 but not Kv2.2 channels was detected in intact rat superior cerebellar arteries and in single smooth muscle cells. Stromatoxin, a high-affinity inhibitor of Kv2 channels, reduced smooth muscle Kv currents by 61% at saturating concentrations (EC50 36 nmol/L). Further, stromatoxin (10–100 nmol/L) induced pronounced vasomotion in 48% of the vessels studied. In vessels not exhibiting vasomotion, stromatoxin did not affect myogenic reactivity. Notably, in vessels exhibiting stromatoxin-induced vasomotion, pressure increases evoked two effects: First, they facilitated the occurrence of random vasodilations and/or vasoconstrictions, disturbing the myogenic response (24% of the vessels). Second, they modified the vasomotion by decreasing its amplitude and increasing its frequency, thereby destabilizing myogenic tone (76% of the vessels). Our study demonstrates that (i) Kv2.1 channels are the predominantly expressed Kv channels in smooth muscle cells of rat superior cerebellar arteries, and (ii) Kv2.1 channels provide a novel type of negative feedback mechanism in myogenic autoregulation by preventing vasomotion and thereby safeguarding the myogenic response.
A Methodical Evaluation of Teachers’ Knowledge and Practices of Differentiation in Basic Schools in the Effutu Municipality of Ghana

Teachers’ knowledge of differentiation and how they practice differentiation was evaluated in fifteen (15) Basic Schools of the Effutu Municipality. The study was guided by two (2) research questions and two (2) hypotheses. The study adopted the Vygotsky (1978) socio-cultural learning theory as the theoretical framework. A qualitative research method was employed as the approach and a case study as the design for the study. Relying on a primary data, a multi-stage sampling method which involved purposive sampling and simple random sampling was used to select the samples. The analyses revealed that the teachers have very high knowledge with respect to strategies of differentiation. Also, the frequency of implementation of differentiation in the subject areas was very good as only 3.3% of the selected teachers do not implement it in any of the subject areas they teach. It was found the proportion of teachers who implemented differentiation in core subjects like Mathematics, English Language and Natural Science were not significantly different from those who do not. Though, the result was generally reassuring, the study made recommended that enhanced supervision, and continuous professional development training therein for improving the situation.
Evaluation of bending after impact and piezoresistive behavior of seawater aged glass fiber reinforced polymer composites containing hybrid carbon nanofillers

The effect of low-velocity impact loading and seawater aging on the residual bending properties of glass fiber reinforced polymers (GFRPs) was evaluated. The self-sensing capability of the composite laminates provided by a hybrid combination of multiwall carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) was also examined. The composite laminates were fabricated by RTM with the incorporation of different contents of MWCNTs and GNPs onto the glass fiber surface using the spray coating technique. Impact tests were performed on specimens with and without seawater (SW) aging and then bending specimens were taken to evaluate the after-impact bending behavior. An important reduction in mechanical properties of composite laminates produced by SW aging, caused by plasticization and swelling effects of the polymer matrix, was confirmed. Despite this physical degradation in the mechanical behavior of GFRP composites, a positive synergistic effect of the carbon nanostructures (CNSs) in the composite laminates was observed. Carbon nanofillers cause the maximum force during the impact test increase in comparison with neat specimens; this effect was exhibited by both samples, with and without seawater aging. Previous impact damage reduced flexural strength and flexural modulus of dry (14% and 43%, respectively) and wet samples (15% and 26%, respectively); however, the reduction in flexural strength is slightly smaller in a certain hybrid combination of CNSs. Another important finding was that the self-sensing capability of GFRPs with CNSs was preserved, even after the impact loading and even after the seawater aging, making this technique suitable for structural health monitoring of marine components.
The mathematics behind chimera states

Chimera states are self-organized spatiotemporal patterns of coexisting coherence and incoherence. We give an overview of the main mathematical methods used in studies of chimera states, focusing on chimera states in spatially extended coupled oscillator systems. We discuss the continuum limit approach to these states, Ott-Antonsen manifold reduction, finite size chimera states, control of chimera states and the influence of system design on the type of chimera state that is observed.
