description: We present the results of a new survey of 23 molecular clouds for the Zeeman effect in OH undertaken with the ATNF Parkes 64-m radio telescope and the NRAO Green Bank 43-m radio telescope. The Zeeman effect was clearly detected in the cloud associated with the HII region RCW 38, with a field strength of 38+/-3 micro-Gauss, and possibly detected in a cloud associated with the HII region RCW 57, with a field strength of -203+/-24 micro-Gauss. The remaining 21 measurements give formal upper limits to the magnetic field strength, with typical 1-sigma sensitivities <20 micro-Gauss. For 22 of the molecular clouds we are also able to determine thecolumn density of the gas in which we have made a sensitive search for the Zeeman effect. We combine these results with previous Zeeman studies of 29 molecular clouds, most of which were compiled by Crutcher (1999), for a comparsion of theoretical models with the data. This comparison implies that if the clouds can be modeled as initially spherical with uniform magnetic fields and densities that evolve to their final equilibrium state assuming flux-freezing then the typical cloud is magnetically supercritical, as was found by Crutcher (1999). If the clouds can be modeled as highly flattened sheets threaded by uniform perpendicular fields, then the typical cloud is approximately magnetically critical, in agreement with Shu et al. (1999), but only if the true values of the field for the non-detections are close to the 3-sigma upper limits. If instead these values are significantly lower (for example, similar to the 1-sigma limits), then the typical cloud is generally magnetically supercritical.

mammary gland

description: In recently published text-books on lymphatics (cf. Yoffey and Courtice, 1956; Rusznyäk, Foldi and Szabo, 1960) no mention is made of mammary lymph or lymphatics. Moreover, Linzell (1959) emphasizes in a review article "Physiology of the Mammary Glands”, that there are no published figures on the flow and composition of mammary lymph. Nothing has been published on the mechanism of removal of milk constituents from the mammary gland or on the role of the lymphatics in this process.The interpretation of the results described in this thesis relate to the physiology of tissue fluid and lymph. It has also been necessary to appreciate the variations which may occur in the disposition of the lymphatics of the mammary gland and the routes by which lymph drains from it. For these reasons, the introduction includes a review of certain aspects of the physiology of the lymphatic system and a description of the anatomy of the lymphatic system of the udder.

description: A new organic-inorganic hybrid material, CoCl2N,N'-(1,2-phenylene)bis(2-aminobenzamide)@Al-SBA-15, was synthesized by modification of Al-SBA-15 with (3-chloropropyl) trimethoxysilane (CPTMS), then the ligand was covalently attached to CPTMS@Al-SBA-15 and finally addition of CoCl2 to form the complex. The mesoporous CoCl2NN'PhBIA@Al-SBA-15 was an efficient catalyst in the preparation of 3-benzoxazol-2-yl-chromen-2-one derivatives through reaction of different coumarin-3-carboxylates and 2-aminophenol derivatives. The nanocatalyst increased rate and facility of the aforementioned reaction and had influence in the green synthesis of different 3-benzoxazol-2-yl-2H-chromen-2-one derivatives. The nanocatalyst was characterized by N2 adsorption–desorption, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS). Some advantages of this procedure are mild reaction condition, high yields of 3-benzoxazol-2-yl-2H-chromen-2-one, short reaction times, environmentally benign, recoverability of the catalyst and reusability without significant loss of its catalytic performance.

description: The growing complexity of the power grid, driven by increasing share of distributed energy resources and by massive deployment of intelligent internet-connected devices, requires new modelling tools for planning and operation. Physics-based state estimation models currently used for data filtering, prediction and anomaly detection are hard to maintain and adapt to the ever-changing complex dynamics of the power system. A data-driven approach based on probabilistic graphs is proposed, where custom non-linear, localised models of the joint density of subset of system variables can be combined to model arbitrarily large and complex systems. The graphical model allows to naturally embed domain knowledge in the form of variables dependency structure or local quantitative relationships. A specific instance where neural-network models are used to represent the local joint densities is proposed, although the methodology generalises to other model classes. Accuracy and scalability are evaluated on a large-scale data set representative of the European transmission grid.

description: Small craters of the lunar maria are observed to be in a state of equilibrium, in which the rate of production of new craters is, on average, equal to the rate of destruction of old craters. Crater counts of multiple lunar terrains over decades consistently show that the equilibrium cumulative size-frequency distribution (SFD) per unit area of small craters of radius >r is proportional r^(-2), and that the total crater density is a few percent of so-called geometric saturation, which is the maximum theoretical packing density of circular features. While it has long been known that the primary crater destruction mechanism for these small craters is steady diffusive degradation, there are few quantitative constraints on the processes that determine the degradation rate of meter to kilometer scale lunar surface features. Here we combine analytical modeling with a Monte Carlo landscape evolution code known as the Cratered Terrain Evolution Model to place constraints on which processes control the observed equilibrium size-frequency distribution for small craters. We find that the impacts by small distal ejecta fragments, distributed in spatially heterogeneous rays, is the largest contributor to the diffusive degradation which controls the equilibrium SFD of small craters. Other degradation or crater removal mechanisms, such cookie cutting, ejecta burial, seismic shaking, and micrometeoroid bombardment, likely contribute very little to the diffusive topographic degradation of the lunar maria at the meter scale and larger.

description: Prolyl oligopeptidase (POP) enzyme has been studied for various disorders, viz. Schizophrenia, Alzheimer’s, Parkinson’s, Depression, Inflammation, etc., for three decades, but no drug has passed through the clinical trials, possibly because of indigent pharmacokinetics. This might have been a result of similar structures of drug candidates. This study aimed at identifying novel small non-peptidomimetic inhibitors for POP enzyme that could serve as a lead for developing newer drugs. Structure-based virtual screening of molecules of MolMall database was conducted on the POP enzyme (PDB ID 3DDU) to identify potential hits. The hits identified were subjected to computational pharmacokinetic screening followed by molecular mechanics/generalized Born and surface area studies to estimate the binding free energy of the docked complexes. After that, nine hits were selected and tested for POP inhibitory activity, among which one compound MM 4 was found to be most potent with EC50 of 100 µM. Compound MM 4 was further subjected to molecular dynamics simulations to study the overall stability of the ligand–protein complex. The compound interacted strongly with catalytic amino acid Arg643 by forming salt and water bridges; it also interacted well with amino acids Phe173, Arg252 and Met235. This study provides a lead molecule for further development of POP inhibitors. Communicated by Ramaswamy H. Sarma

description: Single-crystals of binuclear neutral sulfur-nitrosyl iron complex with 2-mercaptobenzthiazole ligand [Fe2(С7Н4NS2)2(NO)4] have been obtained (BTz). From X-ray data, BTz has a centrosymmetric dimeric structure, with the iron atoms being linked through the µ-N-C-S bridge. As follows from mass-spectra of the BTz gas phase, the complex is stable in the crystalline state under normal conditions (ambient temperature, standard humidity) and releases nitric oxide upon heating. Using amperometry, kinetics of NO release by BTz in 1% dimethylsulfoxide aqueous solutions has been studied: release of NO was shown to occur immediately upon dissolution in protic media. BTz inhibited growth of K562 leukemia and SKOV3 ovarian carcinoma cells in vitro and induced apoptosis via activation caspases 3 and 7.

Fluctuation Effects on the Quadrupolar Ordering in Magnetic Field

description: Effects of magnetic field on the quadrupolar ordering are investigated with inclusion of fluctuation of order parameters. For the simplest model with the nearest-neighbor quadrupolar interaction, the transition temperature and the specific heat are derived by the use of the recently proposed effective medium theory. It is shown that magnetic field H has two competing effects on the quadrupolar ordering; one is to encourage the ordering by suppressing the fluctuation among different components of order parameters, and the other is to block the ordering as in antiferromagnets. The former is found to be of order H^2 and the latter of order H^4. Hence the fluctuation is suppressed for weak fields, and the transition temperature increases with magnetic field. The fluctuation effect is so strong that the entropy released at the quadrupolar ordering is only about half of the full value ln 4 even without the Kondo effect.

Reparation and the German financial system, 1919-1924

description: It has often been said that the reparation question was the "stone in the road" of German democracy. When applied to the period between 1919 and 1924, this statement has usually had one of two meanings. In the mouths of the moderate politicians who formed the early governments of the Weimar Republic it has been a reference to the way in which the reparation problem handicapped them in their rivalry with opposition groups of the extreme Left and Right, Nationalist groups, it is claimed, profited by being able to condemn the policy of "fulfilment" as unpatriotic; while communists made much capital out of the charge that, by paying reparation, the government was conniving at the exploitation of the German working class by world capitalism. Reparation payments were, on this view , a hindrance to German democracy because they embarrassed and weakened those parties which were most closely associated with the democratic Weimer constitution.

description: The problem of singularities associated with Dirac strings and closed timelike curves in classical solutions of pure gravity is analyzed here. A method to eliminate these is introduced and established first for the Taub-NUT geometry. This is superceded by a smooth solution of first order field equations, which is defined to be a unique extension of the Taub Universe to a degenerate metric phase. As an additional feature, this framework naturally provides a geometric interpretation of the magnetic charge in the context of gravity theory without matter. Finally, exploiting the two phases of the metric determinant, we find a (smooth and unique) continuation of the Misner geometry as well, ridding it of closed timelike worldlines which exist in its otherwise Einsteinian manifestation.

description: High-temperature electrolysis (HTE) is a promising technology for achieving high-efficiency power-to-gas, which mitigates the renewable curtailment by transforming wind or solar energy into fuels. Different from low-temperature electrolysis, a considerable amount of the input energy is consumed by auxiliaries in an HTE system for maintaining the temperature, so the studies on systematic description and parameter optimization of HTE are essentially required. A few published studies investigated HTE's systematic optimization based on simulation, yet there is not a commonly used analytical optimization model which is more suitable for integration with power grid. To fill in this blank, a concise analytical operation model is proposed in this paper to coordinate the necessary power consumptions of auxiliaries under various loading conditions of an HTE system. First, this paper develops a comprehensive energy flow model for an HTE system based on the fundamentals extracted from the existing work, providing a quantitative description of the impacts of condition parameters, including the temperature and the feedstock flow rates. A concise operation model is then analytically proposed to search for the optimal operating states that maximize the hydrogen yield while meeting the desired system loading power by coordinating the temperature, the feedstock flows and the electrolysis current. The evaluation of system performance and the consideration of constraints caused by energy balances and necessary stack requirements are both included. In addition, analytical optimality conditions are obtained to locate the optimal states without performing nonlinear programming by further investigating the optimization method. A numerical case of an HTE system is employed to validate the proposed operation model, which proves to not only improve the conversion efficiency but also enlarge the system load range.

description: This paper describes a method to do ab initio molecular dynamics in electronically excited systems within the random phase approximation (RPA). Using a dynamical variational treatment of the RPA frequency, which corresponds to the electronic excitation energy of the system, we derive coupled equations of motion for the RPA amplitudes, the single particle orbitals, and the nuclear coordinates. These equations scale linearly with basis size and can be implemented with only a single holonomic constraint. Test calculations on a model two level system give exact agreement with analytical results. Furthermore, we examined the computational efficiency of the method by modeling the excited state dynamics of a one-dimensional polyene lattice. Our results indicate that the present method offers a considerable decrease in computational effort over a straight-forward configuration interaction (singles) plus gradient calculation performed at each nuclear configuration.
Some aspects of the pure theory of international trade

Year: 1962
Subjects: subject: international trade
subject: monetary policy
subject: neo-Walrasian analysis
subject: Heckscher-Ohlin theorem
subject: Commerce

description: A traditional dichotomy exists in the theory of international trade between, on the one hand, the monetary theory and its associated problems which arise because different money circulates in different countries, because each country has its own central bank and controls its own monetary policy, and because money is treated as a commodity with a direct utility of its own and, on the other hand, the pure theory which is concerned with the real factors underlying the monetary problems. This thesis is concerned solely with the latter. More precisely, our interest centres upon the application of the neo-Walrasian analysis of value and welfare to some of the traditional questions posed in trade theory. The pure theory of international trade itself can be subdivided broadly between 'positive' contributions, intended for purposes of explanation and prediction, and normative contributions relating international trade to economic welfare. In the positive field, and it is with problems arising here that we are primarily concerned, there has been a recent trend towards the empirical verification of different hypotheses. However, though this trend is quite marked in the theory of comparative costs [107] and in connection with the Heckscher-Ohlin theorem that a country's exports use intensively the country's abundant factor of production [108; 109]> id is scarcely noticeable among the great bulk of pure theory writings which are concerned with the formulation of ' logically true' propositions which, in the nature of things, cannot be refuted empirically. The majority of these have been developed within the context of the familiar two-good, two factor model with its additional assumptions of linear and homogeneous production functions with diminishing return*along isoquants, full employment, profit maximisation and perfect competition.

An experimental study of direct and compound nuclear processes in neutron and deuteron induced reactions

Year: 1962
Subjects: Nuclear reactions

description: Although our knowledge of the interaction between nucleons is still far from complete, it has been clear for some time that internucleon forces have an extremely complex nature. However, even the consequences of a known simple interaction are difficult to predict for a many-body system such as the nucleus. A great deal of effort has therefore been spent on developing simple models each of which emphasises a particular aspect of nuclear structure. Two of these, the compound nucleus and direct interaction models, place emphasis on nuclear reactions; and since many of the experimental results reported in the following chapters can only be interpreted on the basis of one or the other of these two models, a brief outline of their properties is presented in this chapter.

description: The dependence of the spin reorientation transition in ultra-thin ferromagnetic films on external magnetic fields is studied. For different orientations of the applied field with respect to the film, phase diagrams are calculated within a mean field theory for the classical Heisenberg model. In particular we find that the spin reorientation transition present in this model is not suppressed completely by an applied field, as the magnetization component perpendicular to the field may show spontaneous order in a certain temperature interval.

description: Technology is influencing education, providing new delivery and assessment models. A combination between online and traditional course, the hybrid (blended) course, may present a solution with many benefits as it provides a gradual transition towards technology enabled education. This research work provides a set of definitions for several course delivery approaches, and evaluates five years of data from a course that has been converted from traditional face-to-face delivery, to hybrid delivery. The collected experimental data proves that the revised course, in the hybrid delivery mode, is at least as good, if not better, than it previously was and it provides some benefits in terms of student retention.

Subjects: Electric discharges through gases

description: This thesis describes an experimental study of the motion of a glow discharge under the influence of a strong transverse magnetic field, at moderate gas pressures. Conditions were generally such that WeTe was of the order of 1, where We is the electron cyclotron frequency, and Te the mean time between the collisions of an electron with neutral gas molecules. Experiments were mostly performed with discharge currents of the order of tens of milliamperes, so that the directed velocity given to the gas by the ions and electrons of the moving discharge was negligible compared with the velocity of the discharge.

description: Objective: This study aims to assess the measurement properties of the Major Depression Inventory (MDI) in a clinical sample of primary care patients. Design: General practitioners (GPs) handed out the MDI to patients aged 18–65 years on clinical suspicion of depression. Setting: Thirty-seven general practices in the Central Denmark Region participated in the study. Patients: Data for 363 patients (65% females, mean age: 49.8 years, SD: 17.7) consulting their GP were included in the analysis. Main outcome measures: The overall fit to the Rasch model, individual item and person fit, and adequacy of response categories were tested. Statistical tests for local dependency, unidimensionality, differential item functioning, and correct targeting of the scale were performed. The person separation reliability index was calculated. All analyses were performed using RUMM2030 software. Results: Items 9 and 10 demonstrated misfit to the Rasch model, and all items demonstrated disordered response categories. After modifying the original six-point to a five-point scoring system, ordered response categories were achieved for all 10 items. The MDI items seemed well targeted to the population approached. Model fit was also achieved for core symptoms of depression (items 1–3) and after dichotomization of items according to diagnostic procedure. Conclusion: Despite some minor problems with its measurement structure, the MDI seems to be a valid instrument for identification of depression among adults in primary care. The results support screening for depression based on core symptoms and dichotomization of items according to diagnostic procedure.Key pointsThe Major Depression Inventory (MDI) is widely used for screening, diagnosis and monitoring of depression in general practice.This study demonstrates misfit of items 9 and 10 to the Rasch model and a need to modify the scoring systemThe findings support screening for depression based on core symptoms and dichotomization of items according to diagnostic procedure.Minor problems with measurement structure should be addressed in future revisions of the MDI.

description: We report evidence for a new class of variable star, which we dub millimagnitude RR Lyrae (mmRR). From K2 observations of the globular cluster M4, we find that out of 24 horizontal branch stars not previously known to be RR Lyrae variables, two show photometric variability with periods and shapes consistent with those of first overtone RR Lyrae variables. The variability of these two stars, however, have amplitudes of only one part in a thousand, which is ${\sim}$200 times smaller than for any RR Lyrae variable in the cluster, and much smaller than any known RR Lyrae variable generally. The periods and amplitudes are: 0.33190704 d with 1.0 mmag amplitude and 0.31673414 d with 0.3 mmag amplitude. The stars lie just outside the instability strip, one blueward and one redward. The star redward of the instability strip also exhibits significant multi-periodic variability at lower frequencies. We examine potential blend scenarios and argue that they are all either physically implausible or highly improbable. Stars such as these are likely to shed valuable light on many aspects of stellar physics, including the mechanism(s) that set amplitudes of RR Lyrae variables.

description: This thesis contains most of the observations, experiments and conclusions resulting from work on the substitution reactions of some octahedral metal complexes. It is divided into four parts. The first chapter is a summary of the effects which are expected to control the rates of inorganic nucleophilic substitutions. The results discussed are those which the author considers are peculiarly inorganic rather than organic; although some overlap is inevitable. It is not intended to be a literature review, and is restricted mainly to octahedral systems. A discussion of the reactions of square planar complexes is not given, nor is any discussion made in regard to electron transfer reactions. The succeeding three chapters have their individual introductions. The intended purpose of these introductions is to give a brief survey of the previous work carried out on the particular problem under investigation. It was hoped by this to indicate clearly that a problem existed, and that it might be solved by the experiments that have been carried out. It was considered that the nature of the chosen topics did not warrant one long-, review type and perhaps perfunctory general introduction at the beginning of the thesis.

description: Prolyl oligopeptidase enzyme has been studied for various disorders viz. Schizophrenia, Alzheimer’s, Parkinson’s, Depression, Inflammation etc. for three decades, but, no drug has passed through the clinical trials, possibly because of indigent pharmacokinetics. This might have been a result of similar structures of drug candidates. This study aimed at identifying novel small non-peptidomimetic inhibitors for prolyl oligopeptidase enzyme that could serve as a lead for developing newer drugs. Structure-based virtual screening of molecules of molmall database was conducted on the prolyl oligopeptidase enzyme (PDB ID 3DDU) to identify potential hits. The hits identified were subjected to computational pharmacokinetic screening followed by molecular mechanics/generalized Born and surface area studies to estimate the binding free energy of the docked complexes. After that, nine hits were selected and tested for prolyl oligopeptidase inhibitory activity, amongst which one compound MM 4 was found to be most potent with EC50 of 100 µM. Compound MM 4 was further subjected to molecular dynamics simulations to study the overall stability of the ligand-protein complex. The compound interacted strongly with catalytic amino acid Arg643 by forming salt and water bridges; it also interacted well with amino acids Phe173, Arg252, and Met235. This study provides a lead molecule for further development of prolyl oligopeptidase inhibitors.

Opsiphanes fabricii

description: Opsiphanes fabricii (Boisduval, 1870)
(Figs 169–186)
 Diagnosis. The male of Opsiphanes fabricii differs from the males of Opsiphanes jacobsorum and Opsiphanes periphetes stat. nov. in the DHW with a defined submarginal band extending to the anal region, usually as wide as the DFW oblique band, between CuA 1 and 2A. The female of Opsiphanes fabricii, on the other hand, differs from the female of Opsiphanes jacobsorum in the yellow DHW submarginal band, and from the female of Opsiphanes periphetes stat. nov. in the continuous DHW submarginal band between the veins, from the costal margin to, usually, M 2; the DHW submarginal band has the same width as the DFW oblique band (Figs 169a, 171a). Opsiphanes fabricii and Opsiphanes merianae stat. rest. are practically indistinguishable by the external morphology, and are differentiated by means of the genitalia. While the male of Opsiphanes fabricii has the tegumen in dorsal view with an anteriorly projected margin, in the male of Opsiphanes merianae stat. rest. the anterior margin of the tegumen has a slight median concavity. The female of Opsiphanes fabricii has a C-shaped signum while Opsiphanes merianae stat. rest. has two parallel signa. The geographical distribution can also be used to separate the two species; while Opsiphanes fabricii subspecies are trans-Andean, Opsiphanes merianae stat. rest. subspecies are cis-Andean. Opsiphanes fabricii is closely related to Opsiphanes jacobsorum, Opsiphanes merianae stat. rest. and Opsiphanes periphetes stat. nov. (genetic distance 0.9–1.2%, 1.2–1.9% and 1.0–1.7%, respectively).
 Male genitalia. Tegumen in dorsal view with anterior margin anteriorly projected, shorter than the uncus; anterior projection of saccus in lateral view twice as long as dorsal arms of saccus (Fig. 179).
 Female genitalia. Lamella antevaginalis membranous medially and sclerotized laterally; lamella postvaginalis rounded medially; ostium with weaker sclerotization than lamella ante and postvaginalis; corpus bursae longer than the ductus bursae, with C-shaped signum (Fig. 180).
 Variation. Subspecies vary in the following characters: DFW, the width of the band inside the discal cell, and in the recesses of the anterior and posterior margins of this band; the width and length of the oblique band; due to variations in the width of these bands, the bifurcated appearence is not always continuous. DHW, the width of the submarginal band. VHW, the zigzag submarginal line EIII is not always evident (Figs 169–178).

description: Background: Caregivers of stroke survivors often suffer depressive symptoms that interfere with their own health. Early recognition may lead to attenuation of symptoms and better health and well-being for caregivers. Objective: We examined characteristics of caregivers and stroke survivors associated with caregivers’ depressive symptoms in the early poststroke period. Methods: We conducted a prospective, longitudinal exploratory observational study with a convenience sample of 63 caregivers of older adult (≥ 65 years) stroke survivors recruited from urban acute-care settings. We enrolled caregivers by 2 weeks poststroke (T1) and revisited them 4 weeks later (T2). Depressive symptoms were measured using the Patient Health Questionnaire-9. A separate unadjusted linear mixed model was computed to explore significant associations between each caregiver or stroke-survivor characteristic and depressive symptoms. Results: Caregivers, on average, reported mild depressive symptoms at T1 and T2. Each of the following characteristics was independently associated with caregiver depressive symptoms over the first 6 weeks poststroke: caregiver uncertainty (p p p = 0.858 on waking, p = 0.231 evening), coping (p p = 0.006), race (p = 0.022), income (p = 0.001), time spent on care (p = 0.039), and stroke-survivor race (p = 0.033) and functional status (p = 0.003). At T2, caregiver depressive symptoms were correlated with evening cortisol level (p = 0.001). Conclusions: Caregiver and stroke-survivor characteristics may help identify caregivers at highest risk for early depressive symptoms and guide interventions aimed at their resolution.

description: Waste oil fly ash (OFA) collected from disposal of power generation plants was treated by physicochemical activation technique to improve the surface properties of OFA. This synthesized material was further used for potential hydrogen sulfide (H2S) adsorption from synthetic natural gas. The raw OFA was basically modified with a mixture of acids (20% nitric acid [HNO3] and 80% phosphoric acid [H3PO4]), and it was further treated with 2 M potassium hydroxide (KOH) to enhance the surface affinity as well as surface area of synthesized activated carbon. Correspondingly, it enhanced the adsorption of H2S. Crystallinity, surface morphology, and pore volume distribution of prepared activated carbon were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) analyses. Fourier transform infrared (FTIR) study was also performed to identify the functional groups during different synthesis stages of modified activated carbon. The Langmuir, Freundlich, Sips, and dual-site Langmuir (DSL) models were used to study the kinetic and breakthrough behavior of H2S adsorption over alkali-modified activated carbon. Modeling results of isotherms indicated that OFA has dual sites with high and low affinity for H2S adsorption. The Clark model, Thomas model, and Yoon-Nelson model were used to examine the effects of flow rate and inlet concentration on the adsorption of H2S. Maximum uptake capacity of 8.5 mg/g was achieved at 100 ppm inlet concentration and flow rate of 0.2 L/min. Implications: Utilization of worthless oil fly ash from power plant is important not only for cleaning the environment but also for solid waste minimization. This research scope is to eradicate one pollutant by using another pollutant (waste ash) as a raw material. Chemical functionalization of synthesized activated carbon from oil fly ash would lead to attachment of functional groups of basic nature to attract the acidic H2S. Such type of treatment can enhance the uptake capacity of sorbent several times.

description: The North-western Queensland region has a moderate to rugged relief ( Plate III, Figs. 1 and 2), and the Precambrian rocks under review crop out over about 16,000 square miles, Cloncurry and Mt. Isa are the main centres, Cloncurry is situated about 210 miles south of the Gulf of Carpenteria and about 450 miles west of Townsville, and approximately 1,300 air route miles from Canberra via Sydney. Access in the region is generally poor and all of the work was done using a 4-wheel drive vehicle adapted for cross country work and camping (Plate IV, Figs. 1 and 2).
