Published: May 2024

Land cover change in the watershed area in Ambon City has an impact on land degradation, water pollution, flooding and erosion. Therefore, the utilization and efficiency of land cover in the watershed area must be improved based on sustainable land cover planning. This study aims to analyze land cover changes in the Wae Heru watershed, Ambon City in 2013, 2018, and 2023 and predict land cover in 2028. This study used the CA-Markov method to predict land cover in 2028. The results showed that in 2013 the built-up land had an area of 74.25 ha, in 2018 an area of 79.30 ha and in 2023 an area of 88.00 ha and the results of the 2028 prediction of built-up land were 116.96 ha, this is certainly influenced by the increasing number of residents who continue to grow every year. Agricultural land, non-agricultural land and open land continue to decrease in area. The results of this prediction are very useful for the government in making policies related to sustainable spatial planning in the future.

Published: May 2024

Let X be an arbitrary Banach space. The establishment of the Henstock-Kurzweil-Dunford-Stieltjes (HKDS) Integral and Henstock-Kurzweil-Pettis-Stieltjes (HKPS) Integral of an X-valued function over \(\mathbb{R}\) shows a viable and more generalized integration process utilizing the notion of dual spaces and weakly measurable functions. In this manuscript, the authors have discussed about some convergence theorems of Henstock- Kurzweil-Dunford-Stieltjes Integral and Henstock-Kurzweil-Pettis-Stieltjes Integral of X-valued functions on \(\mathbb{R}\) via uniform convergence with respect to the integrand and integrator.

Published: May 2024

In recent years, there has been growing interest in issues relating to pollution and energy consumption, and the resulting regulations have led the construction sector to focus on thermal insulation. The application of bio-based insulation materials can help to minimise the environmental impact of buildings by reducing energy demand both during construction and over the lifetime of the building. Agroforestry biomass plays an interesting role, as its use can reduce greenhouse gas emissions. The aim of this work is to produce insulating panels from agroforestry by-products for low-temperature thermal insulation applications. The insulating panels in this study are produced from coconut palm fibres and their thermophysical properties are determined. They were produced using a human-motricity press and the temperature rise was controlled using the hot-tape method. Characteristics such as calorific value and modelling of temperature rise as a function of time to calculate thermal conductivity, thermal effusivity and diffusivity were determined. The calorific value varies from 3668.0 to 4135.0 and from 3742.0 to 4186.0 cal.g-1 when the moisture content is 11.28 and 10.61%, respectively. The thermal conductivity, effusivity and thermal diffusivity are 0.4 W.m-1.K-1, 760.30 J.m-2.°C-1.s-1/2 and 2.73.10-7 m.s-1, respectively. In view of these results, coconut fibre represents a potential precursor to produce insulating panels.
Highly Dispersed Palladium–Polypyrrole Nanocomposites: In‐Water Synthesis and Application for Catalytic Arylation of Heteroaromatics by Direct C–H Bond Activation

Published: February 2011

AbstractPd@PPy hybrid catalytic materials are synthesized in water via redox polymerization reaction of pyrrole with [Pd(NH3)4Cl2]. The nanocomposites formed are composed of highly dispersed palladium particles which are either zerovalent or easily reducible, and are embedded in spherical polypyrrole globules. A unique combination of high palladium dispersion (NP size: 2.4 nm) and elevated palladium content (35 wt%) is obtained. The components of these novel nanocomposites are characterized by means of FTIR, XPS, XRD, SEM, and TEM microscopy techniques. The process of formation in solution is also monitored using UV‐visible and DLS techniques. The application of these novel hybrid nanomaterials in the palladium‐catalyzed direct arylation of heteroaromatics is reported. High efficiency in C–C bond formation is obtained using these materials. Furans and thiophenes are arylated by using bromoarenes. Pd@PPy nanocomposites can efficiently couple n‐butyl furan and n‐butyl thiophene with bromobenzene and bromoquinoline, as well as with activated or deactivated electron‐poor and electron‐rich functionalized bromoarenes. Thus, a clean reaction process is developed that combines the absence of organic ligand in catalytic reactions and easy recovery of Pd@PPy nanocomposite via simple filtration. Preliminary kinetic and post‐catalysis studies suggest a molecular or colloidal soluble active species. These very active species are efficiently delivered by the nanocomposites and susceptible to a surprisingly uniform back redeposition within the polypyrrole support.

AbstractWe review the African Monsoon Multidisciplinary Analysis (AMMA) model inter‐comparison activities for West Africa. The Model Inter‐comparison Project is an evaluation exercise of how global and regional atmospheric models represent seasonal and intra‐seasonal variations of the climate and rainfall over the Sahel. The Land surface Model Inter‐comparison Project in turn focuses on modelling critical land surface processes over West Africa and on their link with the atmosphere. The CHEmistry Model Inter‐comparison Project (CHEMIP) is a comparison of the tropospheric composition as simulated by a number of Chemical Transport Models (CTM) and Chemistry‐Climate Models. We highlight the main model limitations and provide recommendations for future development. Copyright © 2011 Royal Meteorological Society

AbstractWe review the main studies on mesoscale water cycle from the African Monsoon Multidisciplinary Analysis (AMMA) project. The estimations of precipitation and evapotranspiration, which are the coupling terms between the atmosphere and the surface water cycles, are addressed. Advances in the evaluation of the various components of atmospheric and surface water budgets are reported, and the yearly surface budgets for the Benin and Niger AMMA mesoscale sites are given as examples. The major outcomes and limitations of atmosphere‐surface model coupling exercises are also reported. The paper concludes with suggestions on the research directions on which the community should make future efforts. Copyright © 2011 Royal Meteorological Society

AbstractThe AMMA (African Monsoon Multidisciplinary Analysis) project set out to better understand the geophysical processes which govern the evolution of the monsoon and provide the science needed to improve prediction and decision‐support systems. The control exerted by weather and climate on agronomic production, water resources and public health was studied to evaluate the potential for populations to adapt. AMMA made advances which have the potential to improve forecasts from weather to climate scales. Translating them into operational tools for decision making will require improvements to the observational networks, and stronger support for the organizations which generate and disseminate application forecasts.

A Flexible Porphyrin–Annulene Hybrid: A Nonporphyrin Conformation formeso‐Tetraaryldivacataporphyrin
Authors: Pacholska‐Dudziak Ewa , Szterenberg Ludmiła , Latos‐Grażyński Lechosław 
Published: February 2011

AbstractAn annulene–porphyrin hybrid, the diaaza‐deficient porphyrin 5,10,15,20‐tetraaryl‐21,23‐divacataporphyrin, has been synthesized by an extrusion of tellurium atom(s) from 5,10,15,20‐tetraaryl‐21,23‐ditelluraporphyrin under treatment with HCl. In addition, a monoaza‐deficient 5,10,15,20‐tetraaryl‐21‐tellura‐23‐vacataporphyrin was formed in the same reaction. The two new members of the vacataporphyrin family were characterized by X‐ray crystallography, as well as UV/Vis and NMR spectroscopy. These aromatic molecules preserve the fundamental structural and spectroscopic features of the parent tetraarylporphyrin. The X‐ray crystal structures of 21,23‐divacataporphyrin and 21‐tellura‐23‐vacataporphyrin show typical porphyrin patterns. The molecules are not strictly planar and show distortion of the annulene moieties. The N22⋅⋅⋅N24 distances (5.23 and 5.09 Å) are considerably longer than in regular porphyrins. For 21,23‐divacataporphyrin, variable‐temperature 1H NMR spectroscopy data allowed the identification of divacataporphyrin stereoisomers differentiated by the geometry of the butadiene bridges. The forms remain in thermodynamic equilibrium.

Published: February 2011

AbstractEmpirical potential has been modified for α‐alanine intermolecular interaction, in order to perform a Periodic Bond Chain (PBC) analysis. Equilibrium and growth shapes have been predicted in vacuum and the equilibrium shape has been successfully modified by the solvent interaction. α‐alanine crystals have been prepared both in pure and in CaCO3 aqueous solution. Then, habit modification was observed and surface morphology analysis has been carried out on metallized crystals. Epitaxial model acting at the α‐alanine/ CaCO3 interfaces is also proposed.

Accurate measurement of deposition rates for growth of Bi‐based oxide thin films
Authors: Zhang Bingsen , Qi Yang 
Published: February 2011

AbstractBi‐based oxide thin films are important superconducting materials because of its wide applicability, high transition temperatures, and low toxicity. To achieve high quality Bi‐based oxide thin films by molecular beam epitaxy (MBE), the composition is a key parameter. Here, Bi, Cu, Cu/Sr and Cu/Ca thin films on glass substrates prepared by MBE have been examined by using both X‐ray reflectivity and surface profiler. The thickness and surface roughness were obtained through calculation and simulation. In comparison with the film thicknesses measured by these two methods, they are in good agreement. The lines of thickness deposition rate (R) versus source temperature (T) are according with LogR=a+b/T based on Clausius‐Clapeyron equation. Moreover, the Bi2.1CaySr1.9‐yCuO6+δ thin films with different composition and thickness were successfully prepared by MBE by applying the thickness deposition rate lines.

PseudoBartter syndrome in eating disorders
Authors: Bahia Amit , Mascolo Margherita , Gaudiani Jennifer L. , Mehler Philip S. 
Published: February 2011

AbstractObjective:PseudoBartter's syndrome, a complex pattern of seemingly unrelated metabolic abnormalities, is frequently seen in patients with eating disorders, particularly those who indulge in purging behaviors. We present two cases that, despite divergent background histories and clinical presentations, possess the unifying pathophysiology that ultimately leads to this syndrome.Method:Case report and review of literature pertaining to Bartter's and PseudoBartter's syndromes.Results:Purging behaviors commonly result in a state of profound dehydration and chloride depletion that leads to the metabolic abnormalities characteristic of inheritable sodium and chloride renal tubular transport disorders. In the eating disorder patient, these abnormalities lead to a propensity towards marked edema formation.Discussion:The metabolic and clinical manifestations of PseudoBartter's syndrome are seen more commonly than previously thought. It is important to appreciate that a complex self‐perpetuating pathophysiology leads to the hypokalemic metabolic alkalosis characteristic of PseudoBartter syndrome. The metabolic abnormalities characteristic of this phenomenon should therefore be viewed in this context and the resulting predilection towards marked edema formation should be borne in mind. © 2011 by Wiley Periodicals, Inc.

Perception of control during episodes of eating: Relationships with quality of life and eating psychopathology
Authors: Jenkins Paul E. , Conley Colleen S. , Rienecke Hoste Renee , Meyer Caroline , Blissett Jacqueline M. 
Published: February 2011

AbstractObjective:Experience of loss of control (LOC) during eating is an important indicator of pathology, although this concept has not received a great deal of research attention. The present study explores how quality of life (QoL) is related to LOC during eating.Method:Three hundred and thirty‐nine female university students completed measures of eating pathology, general psychiatric symptomatology, and QoL. They were subsequently categorized according to the degree of LOC experienced during eating into one of five groups: no binge eating (NBE); objective overeating (OOE); objective binge eating (OBE); subjective binge eating (SBE); and a mixed OBE/SBE group (Mixed).Results:Individuals who experienced LOC during eating reported significantly poorer QoL and more psychiatric symptoms.Discussion:In a nonclinical female sample, LOC during eating appeared to be a more important marker of pathology and poorer self‐reported QoL than the amount of food eaten. © 2011 by Wiley Periodicals, Inc.

Investigating the Phospholylcarbene to Phosphinine Conversion
Authors: Chen Hui , Li Jin , Wang Huaiqiu , Liu Hui , Duan Zheng , Mathey François 
Published: February 2011

AbstractA DFT study suggests that the conversion of arsolylcarbenes into arsenines as described by Märkl proceeds via arsabenzvalenes. A similar conversion does not work with phospholylcarbenes. However, we have found that, in some cases, 1‐diazoalkylphosphole sulfides are converted into phosphinine sulfides whose in situ reduction by triphenylphosphite affords the dicoordinate phosphinines.
Numerical investigation of tube furnace toxicity measurement method (ISO 19700)

Published: February 2011

SUMMARYISO TS 19700 describes a test method for the generation of fire effluent and the identification and measurement of its constituent combustion products. The method has been previously accepted as a British Standard (BS 7990:2003) and as an IEC Standard (IEC 60695‐7‐50), which involves the decomposition of materials or products under various decomposing conditions occurring in different types and stages of real fires. It uses a moving test specimen and a tube furnace at different temperatures and air flow rates as the fire model. Simulations of flow and combustion conditions inside the tube (Purser) furnace were carried out and validated with the measurements. The objective of the present study is to demonstrate the validity of using computational fluid dynamics (CFD)‐based fire field modelling techniques to predict the fire environment inside the tube furnace. These numerical investigations are also used to verify critical experimental operating parameters that affect the performance of the tube furnace and understand the modus operandi of the tube furnace toxicity method.

A comparison of the GWCE and mixed P − P1 formulations in finite‐element linearized shallow‐water models
Authors: Roux D. Y. Le , Walters R. , Hanert E. , Pietrzak J. 
Published: February 2011

SUMMARYThe appearance of spurious pressure modes in early shallow‐water (SW) models has resulted in two common strategies in the finite element (FE) community: using mixed primitive variable and generalized wave continuity equation (GWCE) formulations of the SW equations. One FE scheme in particular, the P − P1 pair, combined with the primitive equations may be advantageously compared with the wave equation formulations and both schemes have similar data structures. Our focus here is on comparing these two approaches for a number of measures including stability, accuracy, efficiency, conservation properties, and consistency. The main part of the analysis centres on stability and accuracy results via Fourier‐based dispersion analyses in the context of the linear SW equations. The numerical solutions of test problems are found to be in good agreement with the analytical results. Copyright © 2011 John Wiley & Sons, Ltd.
Unsteady three‐dimensional boundary layer flow due to a stretching surface in a micropolar fluid
Authors: Ahmad K. , Nazar R. , Ishak A. , Pop I. 
Published: February 2011

SUMMARYIn this paper, the unsteady three‐dimensional boundary layer flow due to a stretching surface in a viscous and incompressible micropolar fluid is considered. The partial differential equations governing the unsteady laminar boundary layer flow are solved numerically using an implicit finite‐difference scheme. The numerical solutions are obtained which are uniformly valid for all dimensionless time from initial unsteady‐state flow to final steady‐state flow in the whole spatial region. The equations for the initial unsteady‐state flow are also solved analytically. It is found that there is a smooth transition from the small‐time solution to the large‐time solution. The features of the flow for different values of the governing parameters are analyzed and discussed. The solutions of interest for the skin friction coefficient with various values of the stretching parameter c and material parameter K are presented. Copyright © 2011 John Wiley & Sons, Ltd.
Gross and fine anatomy of the respiratory vasculature of the mudskipper, Periophthalmodon schlosseri (Gobiidae: Oxudercinae)
Authors: Gonzales Tomas T. , Katoh Masaya , Ghaffar Mazlan Abd. , Ishimatsu Atsushi 
Published: February 2011

AbstractTo illustrate vascular modification accompanying transition from aquatic to amphibious life in gobies, we investigated the respiratory vasculatures of the gills and the bucco‐opercular cavities in one of the most terrestrially‐adapted mudskippers, Periophthalmodon schlosseri, using the corrosion casting technique. The vascular system of Pn. schlosseri retains the typical fish configuration with a serial connection of the gills and the systemic circuits, suggesting a lack of separation of O2‐poor systemic venous blood and O2‐rich effluent blood from the air‐breathing surfaces. The gills appear to play a limited role in gas exchange, as evidenced from the sparsely‐spaced short filaments and the modification of secondary lamellar vasculature into five to eight parallel channels that are larger than red blood cell size, unlike the extensive sinusoidal system seen in purely water‐breathing fishes. In contrast, the epithelia of the bucco‐opercular chamber, branchial arches, and leading edge of the filaments are extensively laden with capillaries having a short (<10 μm) diffusion distance, which strongly demonstrate the principal respiratory function of these surfaces. These capillaries form spiral coils of three to five turns as they approach the epithelial surface. The respiratory capillaries of the bucco‐opercular chamber are supplied by efferent blood from the gills and drained by the systemic venous pathway. We also compared the degree of capillarization in the bucco‐opercular epithelia of Pn. schlosseri with that of the three related intertidal‐burrowing gobies (aquatic, non‐air‐breathing Acanthogobius hasta; aquatic, facultative air‐breathing Odontamblyopus lacepedii; amphibious air‐breathing Periophthalmus modestus) through histological analysis. The comparison revealed a clear trend of wider distribution of denser capillary networks in these epithelia with increasing reliance on air breathing, consistent with the highest aerial respiratory capacity of Pn. schlosseri among the four species.

Published: February 2011

AbstractIn this article, a novel method is presented to improve the coupling of dielectric resonator antenna (DRA) excited by a waveguide slot at the shorted end.A rectangular DRA is excited by a thick ground plane slot, which is fed by a capacitive waveguide junction (CWJ)‐coupled waveguide end. The objective of using a CWJ is to substantially increase the power coupling to the DRA. Measurements were carried out to verify the design, and a reasonable agreement between them is obtained. © 2011 Wiley Periodicals, Inc.
