description: Current development administration theory stresses action-oriented public management in national development. Indonesia's Fourth Five-Year Plan (1984-1989) reflects this emphasis, calling for accelerated efforts to improve managerial capabilities for development through management training and research, utilizing development experiences and indigenous resources. Examination of managers' work activities is a prerequisite to devising training to produce action-oriented managerial capabilities. Mintzberg's ten-role theory is a tool for such scrutiny. The literature on work activity demonstrates its applicability in various American organizational settings. With this conceptual framework and a modified Delphi method, this study explored the role requirements and skill needs of 100 middle-level development managers in the Indonesian public service. Just over half the respondents reported planning, organizing, staffing, directing, coordinating, reviewing, data processing, and "other" assignments in their job descriptions. Only 12 percent were able to estimate time spent in function performance. Activities cited corresponded to Mintzberg's ten roles: figurehead, leader, liaison, monitor, disseminator, spokesman, entrepreneur, disturbance handler, resource allocator, and negotiator. Two additional roles were identified: technical expert and manager of the sociocultural environment. A need for skill development was expressed, particularly in entrepreneurship, leadership, and management of the environment. Formal and on-the-job training were rated high in importance; coaching by the boss, adjustment to local traditions, and self-teaching were less frequently cited. Indigenous culture traits were recognized as both supporting and inhibiting development. Approximately one-third of the respondents remarked on the facilitating aspects of knowledge of local customs and of working through formal and informal local leaders. The findings support recommendations for the following actions: (1) Follow-up studies of roles and skill requirements of Indonesian development managers, particularly in departments with high-priority development programs. (2) Simultaneous establishment of the infrastructure for ongoing research and its applications and validation in training, including research-based review and revision of job descriptions and skill specifications, and of curricula and learning methods. (3) Focus on application of research findings in training. (4) Application of the ongoing findings to national development management resource planning and utilization.

description: We study D-branes of N=2 supersymmetric sigma models. Supersymmetric nonlinear sigma models with 2-dimensional target space have D0,D1,D2-branes, which are realized as A-,B-type supersymmetric boundary conditions on the worldsheet. When we embed the models in the string theory, the Kahler potential is restricted and leads to a 2-dim black hole metric with a dilaton background. The D-branes in this model are susy cycles and consistent with the analysis of conjugacy classes. The generalized metrics with U(n) isometry is proposed and dynamics on them are realized by linear sigma models. We investigate D-branes of the linear sigma models and compare the results with those in the nonlinear sigma models.

AN INVESTIGATION OF THE EFFECT OF RADIATION OF DNA METHYLATION PATTERNS
Creators: name: Kalinich, John F.
Publisher: name: American University
Year: 2023

description: The deleterious effects of radiation exposure have been well documented. However, the exact target of radiation damage has not as yet been discovered. Methylation of DNA has been shown to play a major role in gene expression, carcinogenesis, cellular development and differentiation, and stabilization of DNA conformational states. Therefore this project was undertaken to determine the effects of radiation on DNA methylation patterns. Four lines of cultured mammalian cells were used in this project: V79A03, a Chinese hamster lung fibroblast; HeLa S-3, an epithelial cell line from a human cervix carcinoma; CHO K-1, an epithelial cell line from a Chinese hamster ovary; and C-1300 N1E-115, a mouse neuroblastoma line. The 5-methylcytosine levels in DNA following exposure to cobalt-60 gamma radiation were measured. Induction of metallothionein in V79A03 cells and acetylcholinesterase in C-1300 N1E-115 cells after irradiation was determined and the effect of radiation on cytoplasmic and nuclear levels of DNA methyltransferase was studied and nuclear demethylase activity assayed. This study showed gamma radiation resulted in a decrease of 5-methylcytosine levels in the DNA of cultured mammalian cells. This radiation-induced hypomethylation resulted in the induction of acetylcholinesterase in mouse neuroblastoma cells and metallothionein in Chinese hamster lung fibroblasts and was caused by a decrease in DNA methyltransferase activity in the nucleus after irradiation and not by the presence of a DNA demethylase.

Οι πολυμερικοί οδοντωτοί τροχοί έχουν αρχίσει να αντικαθιστούν τους αντίστοιχούς μεταλλικούς σε όλο και πιο απαιτητικές εφαρμογές δυναμικών συστημάτων. Για το λόγο αυτό απαιτείται πλέον να κατασκευάζονται με μεγάλη διαστασιολογική και γεωμετρική ακρίβεια. Στην παρούσα διπλωματική εργασία διερευνάται η ακρίβεια που μπορεί να επιτευχθεί από τις διάφορες μεθόδους παραγωγής που χρησιμοποιούνται στον τομέα των πολυμερικών οδοντωτών τροχών. Ιδιαίτερη έμφαση δίνεται στη μέθοδο παραγωγής injection-molding, που είναι η κατεξοχήν μέθοδος παραγωγής πολυμερικών τροχών, αλλά και στην τρισδιάστατη εκτύπωση, που αναμένεται να κυριαρχήσει τα επόμενα χρόνια σε πολλούς τομείς της βιομηχανίας. Αν και με τη μέθοδο του Injection-molding μπορούν να επιτευχθούν ακρίβειες που πλησιάζουν εκείνες των κλασικών μεθόδων παραγωγής μεταλλικών οδοντωτών τροχών, η τρισδιάστατη εκτύπωση βρίσκεται ακόμα πίσω στον τομέα αυτό. Ωστόσο, η σωστή επιλογή των παραμέτρων και η βελτιστοποίηση της διαδικασίας παραγωγής μπορεί να βελτιώσει σημαντικά την ακρίβεια του τελικού προϊόντος και να επιτρέψει τη χρήση του σε μια σειρά απαιτητικών εφαρμογών.

description: A certain signed adjacency matrix of the hypercube, which Hao Huang used last year to resolve the sensitivity conjecture, is closely related to the unique, 4-cycle free, 2-fold cover of the hypercube. We develop a framework in which this connection is a natural first example of the relationship between group labeled adjacency matrices with few eigenvalues, and combinatorially interesting covering graphs. In particular, we define a two-eigenvalue cover to be a covering graph whose adjacency spectra differs (as a multiset) from that of the graph it covers by exactly two eigenvalues. We show that walk regularity of a graph implies walk regularity of any abelian two-eigenvalue cover. We also give a spectral characterization for when a cyclic two-eigenvalue cover of a strongly-regular graph is distance regular.

description: Quantum estimation theory provides optimal observations for various estimation problems for unknown parameters in the state of the system under investigation. However, the theory has been developed under the assumption that every observable is available for experimenters. Here, we generalize the theory to problems in which the experimenter can use only locally accessible observables. For such problems, we establish a Cram{é}r-Rao type inequality by obtaining an explicit form of the Fisher information as a reciprocal lower bound for the mean square errors of estimations by locally accessible observables. Furthermore, we explore various local quantum estimation problems for composite systems, where non-trivial combinatorics is needed for obtaining the Fisher information.

title: Photochemical synthesis of heterocyclic compounds

Publisher: name: The Open University

description: The aim of our research was to investigate the photocyclisation of N-substituted imide systems, in order to prepare polycyclic heterocyclic photoproducts of potential pharmaceutical interest. The major group of substrates were N-(dialkylaminoalkyl)succinimides. Irradiation of succinimide Mannich bases (A) leads to two diastereoisomers of 1,3-diazabicyclo[3.3,0]octanes in reasonable yields. The relative stereochemistry was assigned on the basis of spectral data. With substrates (e.g. B) derived from unsymmetrical amines, there is strong orientational preference. Substrates (e.g. G) derived from an unsymmetrical succinimide gave a mixture of products; the preferred orientation of cyclisation is to the more hindered C-1 carbonyl group. Using hydantoin substrates (D) which correspond to succinimides in which a methylene group is replaced by a heteroatom, we found that cyclisation occurs only at the C--4 (imide-like) carbonyl group to give diastereoisomers of 1,3,7 - triazabicyclo[3.3,0]octanes. Glutarimide Mannich bases show many parallels with the succinimide analogues. However, pyrrolidin-2-one Mannich bases did not afford photocyclised products. A minor product (E) is formed by cleavage in the amine fragment. N-(Dialkylaminoethyl) derivatives of saturated imides (F) give rise to ring-expanded photoproducts. This is in contrast to phthalimide substrates (G; n = 2), where photoproducts with a new piperazine ring are obtained. Our hypothesis is that an electron-transfer mechanism operates in the aromatic systems, leading to the possibility of medium/large ring formation, but this is not effective in the succinimides which are poorer electron acceptors. To test this, we irradiated a series o f N-(dialkylaminoalkyl) derivatives of imides with a double bond conjugated with the carbonyl groups, and found that these substrates (H) do give photoproducts with new six- or seven-membered rings. Our results with N-(dialkylaminopropyl)phthallmides (G; n = 3) are not entirely in agreement with earlier reports that medium-ring formation is the major photocyclisation process for phthalimide substrates. Further work is required to extend this comparison of the photocyclisation process for saturated, unsaturated and aromatic N-(dialkylaminoalkyl)imides.
Vitamin D, age, sex and skin pigmentation: An analysisof how recommendations and standards regarding vitamin D need more comprehensive research for policy

description: Vitamin D has long been implicated in health research with its etiology hypothesized in many diseases. As recently as 2011, the Institute of Medicine (IOM), appointed a committee of 14 scientists to re-evaluate the 1994 dietary reference intakes for calcium and vitamin D as ample new research had been conducted to warrant an evaluation of vitamin D supplementation. The efforts were supported by the United States and Canadian governments. Research was evaluated and new recommendations were established. However, the committee of scientists, supported by IOM staff, continues to use the same evaluation methods for vitamin D as they do for all vitamin dietary recommendations, but vitamin D is not a vitamin in the traditional sense. It is a pro-hormone. Vitamin D is not gained solely from diet. It is more readily produced via the conversion of cholesterol to vitamin D through sun exposure. Therefore, traditional methods of evaluation to deduce dietary intakes may not apply for a vitamin that is environmentally influenced. While many scientists are adamant that the recommendation levels for vitamin D should be higher and not all population sub-group dietary needs are being addressed, new methods of evaluation may be what are warranted. It is vital that researchers evaluate novel ways to understand vitamin D and the implications for nutritional policy in the form of dietary recommendations to create more comprehensive recommendation for vitamin D dietary needs. Currently, dietary recommendations are created for life-stage (age range) and sex, but more comprehensive listings by latitude, skin pigmentation, and adiposity might provide for the needs of more individuals.

description: One-dimensional (1D) quantum wires, which are functionalized by magnetic ad-atoms, can host ballistic helical transport. Helicity protects transport from an undesirable influence of material imperfections, and it makes the magnetically doped wire a very promising element for nanoelectronics and spintronics. However, fabricating purely 1D conductors is experimentally very challenging and not always feasible. In this paper, we show that the protected helical transport can exist even in quasi-1D wires. We model the quasi-1D magnetically doped wire as two coupled dense 1D Kondo chains. Each chain consists of itinerant electrons interacting with localized quantum magnetic moments -- Kondo impurities. We have analyzed the regimes of weak-, intermediate-, and strong inter-chain coupling, and we found conditions necessary for the origin of the aforementioned protected transport. Our results may pave the way for experimental realizations of helical states in magnetically doped wires.

description: The ROTSE-IIIa telescope and the SSO-40 inch telescope, both located at Siding Spring Observatory, imaged the early time afterglow of GRB 030418. In this report we present observations of the early afterglow, first detected by the ROTSE-IIIa telescope 211 s after the start of the burst, and only 76 s after the end of the gamma-ray activity. We detect optical emission that rises for ~600 s, slowly varies around R=17.3 mag for ~1400 s, and then fades as a power law of index alpha=-1.36. Additionally, the ROTSE-IIIb telescope, located at McDonald Observatory, imaged the early time afterglow of GRB 030723. The behavior of this light curve was qualitatively similar to that of GRB 030418, but two magnitudes dimmer. These two afterglows are dissimilar to other afterglows such as GRB 990123 and GRB 021211. We investigate whether the early afterglow can be attributed to a synchrotron break in a cooling synchrotron spectrum as it passes through the optical band, but find this model is unable to accurately describe the early light curve. We present a simple model for gamma-ray burst emission emerging from a wind medium surrounding a massive progenitor star. This model provides an effective description of the data, and suggests that the rise of the afterglow can be ascribed to extinction in the local circumburst environment. In this interpretation, these events provide further evidence for the connection between gamma-ray bursts and the collapse of massive stars.

description: We have measured the optical reflectivity $R(ω)$ of $Eu_{0.6}Ca_{0.4}B_{6}$ as a function of temperature between 1.5 and 300 $K$ and in external magnetic fields up to 7 $T$. The slope at the onset of the plasma edge feature in $R(ω)$ increases with decreasing temperature and increasing field but the plasma edge itself does not exhibit the remarkable blue shift that is observed in the binary compound $EuB_{6}$. The analysis of the magnetic field dependence of the low temperature optical conductivity spectrum confirms the previously observed exponential decrease of the electrical resistivity upon increasing, field-induced bulk magnetization at constant temperature. In addition, the individual exponential magnetization dependences of the plasma frequency and scattering rate are extracted from the optical data.

title: Photochemistry of thiophthalimides
Creators: name: Rapley, Patricia Anne
Publisher: name: The Open University
Year: 1986

description: Thiomide photochemistry is of interest because previous photochemical studies of thiocarbonyl compounds have been restricted largely to thioketones, and because the "alloxygen" imides have proved to have a varied and synthetically useful photochemistry. Successful reactions with thiomides might lead to analogous sulphur products that could be readily modified by further chemical reaction. Irradiation of the previously unreported thiophthalimide Mannich bases (A) leads to unusual cleavage products (B and C ), unlike the reaction of related phthalimide Mannich bases, which gives photocyclised compounds. Other N-substituted thiophthalimides that might be expected to undergo photocyclisation via hydrogen transfer are unreactive upon irradiation (except to photooxidation). However, photocycloaddition reactions of N-substituted thiophthalimides with a range of multiply-bonded substrates have proved to be more fruitful. (2+2)-Cycloadducts are obtained with alkenes such as stilbene (adduct structure D ), with alkynes such as diphenylethyne (E), with ketenes such as diphenylketene (F), and with ketenimines. These (2+2)-adducts contain thietane or thiete rings, and in some cases ringcleavage products (G) or ring-opened products (H) are formed. With some alkenes such as methyl acrylate, 2:1 adducts are obtained (I). A substrate (J) designed to produce intramolecular cycloadducts led, surprisingly, to a compound (K) derived by hydrogen abstraction and cyclisation. A brief study of the photophysical properties of the N-substituted thiophthalimides shows that they are weakly luminescent at 77 K, and that the reactive excited state is most probably the lowest (n,pi*) triplet.
DIALECTICISM: A RE-EXAMINATION OF MARXISM

Publisher: name: American University
Year: 2023

description: Efforts to reproduce, enrich, and update Marxism have not only ignored or misinterpreted Marxist philosophy and epistemology, but often reduced Marxism to economism, historicism, humanism, and structuralism. What emerges from this study is a set of new concepts (dialecticism: philosophical, epistemic, and social) and a new methodology (dialectical) for uncovering the nature of the universe, mental phenomena, and human social life. Dialecticism is made up of three distinct, interrelated scientific practices: (1) Dialectical philosophy studies the universe. The principal theme of this part is to show that it is neither matter nor idea but practice which constitutes the very existence of all phenomena. (2) Dialectical epistemology has as its object mental phenomena. Here, the main goal is to understand the existential basis of knowledge, and then, as a subfield of dialectical epistemology, to study the dialectical mode of production of knowledge: dialectical methodology. (3) Dialectical sociology studies social phenomena. This part is devoted to group of theoretical problems at the heart of the most topical concern of Marxism. The research method derives from the questions posed and defined in the dissertation: (1) What is the existential basis of the universe? (2) What is the existential basis of knowledge? (3) What is dialectical methodology? (4) What is the general condition of life? (5) What is the mode of production and reproduction of life? (6) What is social class? (7) What are social institutions? (8) What is state? and (9) What is the world capitalist system? The questions are answered using primarily the secondary sources technique. They culminate in an in-depth examination of the capitalist world system. Central to the discussion is the fact that (1) capitalism is governed by the profit motive, and (2) capitalism is unable to exist and develop by itself. No remedy can be prescribed for liberation of people from the aggressive interest and forces of the capitalist vampire, unless the people destroy the roots of imperialism... They must fight to replace the capitalist system with a new planned humanist mode of life in which people's needs, requirements, wills, interests and their constant development are the chief aim of the process of production and reproduction of life.

N=2 SYM Action as a BRST Exact Term, Topological Yang Mills and Instantons

description: By constructing a nilpotent extended BRST operator $\bs$ that involves the N=2 global supersymmetry transformations of one chirality, we show that the standard N=2 off-shell Super Yang Mills Action can be represented as an exact BRST term $\bs Ψ$, if the gauge fermion $Ψ$ is allowed to depend on the inverse powers of supersymmetry ghosts. By using this nonanalytical structure of the gauge fermion (via inverse powers of supersymmetry ghosts), we give field redefinitions in terms of composite fields of supersymmetry ghosts and N=2 fields and we show that Witten's topological Yang Mills theory can be obtained from the ordinary Euclidean N=2 Super Yang Mills theory directly by using such field redefinitions. In other words, TYM theory is obtained as a change of variables (without twisting). As a consequence it is found that physical and topological interpretations of N=2 SYM are intertwined together due to the requirement of analyticity of global SUSY ghosts. Moreover, when after an instanton inspired truncation of the model is used, we show that the given field redefinitions yield the Baulieu-Singer formulation of Topological Yang Mills.

description: Nuclear structure theory has recently gone through a major renewal with the development of ab initio techniques that can be applied to a large number of atomic nuclei, well beyond the light sector that had been traditionally targeted in the past. Self-consistent Green's function theory is one among these techniques. The present work aims to give an overview of the self-consistent Green's function approach for atomic nuclei, including examples of recent applications and a discussion on the perspectives for extending the method to nuclear reactions, doubly open-shell systems and heavy nuclei.

description: Neglecting spin effects, one introduces here a subtle approximation for the scattering angle, which allows the obtaining of a logarithmic leading Regge pole, consistent with the Froissart-Martin bound. A simple parameterization is also introduced for the proton-proton total cross section. Fitting procedures are implemented only for the highest energy experimental data available. The intercept for a linear approach is obtained, indicating the presence of a soft pomeron. The Tsallis entropy in the impact parameter space is calculated using the Regge pole formalism. This entropy depends on a free parameter, whose value implies the existence of a central or non-central maximum value for the entropy. The hollowness effect is discussed in terms of this parameter.

description: Critical care has displayed an interest in the field of disaster and mass casualty incident response (2). A disaster refers to a man-made or natural event requiring resources from outside a local community to return to pre-event status (3). An incident occurs secondary to similar hazards, requiring an emergency response to protect life, however, may not require resources from outside a local community (4). A mass casualty incident focuses on healthcare system capacity, where casualties rapidly exceed capabilities (5). Here we focus on the timeframe of acute response by intensive care units (ICUs) themselves: a relief phase - where lifesaving and mitigation efforts dominate - and a subsequent recovery phase - where efforts return systems to pre-event status. Significant infrastructure, personnel and equipment resources are required to operate ICUs (6). Disasters and mass casualty incidents are known to result in an influx of critically ill patients (2). Thus, ICU populations must be thought of as especially at risk.Yet, there remains a paucity of well-compiled data from the front-lines of ICU response initiatives, hampering evidence-based guideline production (2). Disaster research theory, though, is well-established (3). Categorical, continuous, or even narrative data reported by responders in the midst of response initiatives represent evidence (7). It is possible that through initial publication and valuating of such reports, we may illuminate intervention effects, variation in experience and practice, and identify gaps and inconsistencies in the literature.The purpose of this scoping review will be to compile and analyze ICU disaster and mass casualty incident response experiences. We intend to characterize ICU experiences - reported by ICUs themselves - to organize quantitative and qualitative data. Quantitative data, in the form of categorical and continuous items reported, will be assessed. Qualitative analyses will be undertaken through narrative inquiry of anecdotes. Outcomes of interest include identification of trends, analyses of existing reports for consistency, typical experience strengths or weaknesses, lessons learned, and best practices. This scoping review represents the first published data compilation and analysis of ICU disaster and mass casualty incident response initiatives.
DIALECTICISM: A RE-EXAMINATION OF MARXISM

subject: Human society

description: Efforts to reproduce, enrich, and update Marxism have not only ignored or misinterpreted Marxist philosophy and epistemology, but often reduced Marxism to economism, historicism, humanism, and structuralism. What emerges from this study is a set of new concepts (dialecticism: philosophical, epistemic, and social) and a new methodology (dialectical) for uncovering the nature of the universe, mental phenomena, and human social life. Dialecticism is made up of three distinct, interrelated scientific practices: (1) Dialectical philosophy studies the universe. The principal theme of this part is to show that it is neither matter nor idea but practice which constitutes the very existence of all phenomena. (2) Dialectical epistemology has as its object mental phenomena. Here, the main goal is to understand the existential basis of knowledge, and then, as a subfield of dialectical epistemology, to study the dialectical mode of production of knowledge: dialectical methodology. (3) Dialectical sociology studies social phenomena. This part is devoted to group of theoretical problems at the heart of the most topical concern of Marxism. The research method derives from the questions posed and defined in the dissertation: (1) What is the existential basis of the universe? (2) What is the existential basis of knowledge? (3) What is dialectical methodology? (4) What is the general condition of life? (5) What is the mode of production and reproduction of life? (6) What is social class? (7) What are social institutions? (8) What is state? and (9) What is the world capitalist system? The questions are answered using primarily the secondary sources technique. They culminate in an in-depth examination of the capitalist world system. Central to the discussion is the fact that (1) capitalism is governed by the profit motive, and (2) capitalism is unable to exist and develop by itself. No remedy can be prescribed for liberation of people from the aggressive interest and forces of the capitalist vampire, unless the people destroy the roots of imperialism... They must fight to replace the capitalist system with a new planned humanist mode of life in which people's needs, requirements, wills, interests and their constant development are the chief aim of the process of production and reproduction of life.

NATIONAL POWER AND INTERNATIONAL VIOLENCE: A MODEL OF NATIONS AND THE INTERNATIONAL SYSTEM

description: This research investigates the problem of international violence, which is two-fold in nature: it causes needless death and it imposes an opportunity cost on future generations. It is my assertion that changes in national power are the major cause for international violence. The distinctive character of the problem is that the impact of international violence in the contemporary era (a period beginning around 1870 and ending around the year 2000) is much greater than that of earlier historical eras. The problem of international violence in the contemporary era differs from international violence in earlier eras for two reasons. First, it differs because the capability for international violence has grown, thereby increasing the number of deaths that result. Second, it differs because the degree of interdependence in the international system has also grown, thereby magnifying the participation in international violence. Three key questions provide the basis for exploring the problem of international violence: (1) What are the patterns of international violence? (2) Why does international violence occur? (3) How can we change patterns of international violence?; Answering these questions consitutes three separate but related research tasks: undertaking an in-depth study of the patterns of international violence and its relation to changes in national power; building a model of the international system (one based on attributes of national power) with international violence as one element; and, carrying out a search for solutions to the problem of international violence using this model. The results of the research are also three-fold. First, it is found that there is an empirical relationship between changes in national power and international violence. Second, it is found that a model of the international system can be used to represent the theoretical relationship between changes in national power and international violence. Third, it is found that in the search for solutions to the problem current policies (exemplified by the "liberal" and "conservative" viewpoints) offer little hope for significantly reducing international violence.

description: Expanding around null hypersurfaces, such as generic Kerr black hole horizons, using co-rotating Kruskal-Israel-like coordinates we study the associated surface charges, their symmetries and the corresponding phase space within Einstein gravity. Our surface charges are not integrable in general. Their integrable part generates an algebra including superrotations and a BMS_3-type algebra that we dub "T-Witt algebra". The non-integrable part accounts for the flux passing through the null hypersurface. We put our results in the context of earlier constructions of near horizon symmetries, soft hair and of the program to semi-classically identify Kerr black hole microstates.

Off mass shell dual amplitude with Mandelstam analyticity

description: A model for the $Q^2$-dependent dual amplitude with Mandelstam analyticity (DAMA) is proposed. The modified DAMA (M-DAMA) preserves all the attractive properties of DAMA, such as its pole structure and Regge asymptotics, and leads to a generalized dual amplitude $A(s,t,Q^2)$. This generalized amplitude can be checked in the known kinematical limits, i.e. it should reduce to the ordinary dual amplitude on mass shell, and to the nuclear structure function when $t=0$. In such a way we complete a unified "two-dimensionally dual" picture of strong interaction. By comparing the structure function $F_2$, resulting from M-DAMA, with phenomenological parameterizations, we fix the $Q^2$-dependence in M-DAMA. In all studied regions, i.e. in the large and low $x$ limits as well as in the resonance region, the results of M-DAMA are in qualitative agreement with the experiment.
