Application of sample S2 to River Batang Kali with low initial turbidity of 32 NTU and high initial turbidity of 502 NTU gave a highest turbidity removal of 69% and 99% respectively. Application to River Selangor with medium initial turbidity- of 87 NTU and high initial turbidity of 466 NTU gave a highest residual turbidity' of 94% and 98.9%,  respectively.Key words: Moringa oleifera seed, selective oil extraction, coagulation, model turbid water (kaolin suspension), river water, turbidity removal.
Review of Wavelet Theory and Its Application Toimage Data Compression
Authors: Khalifa Othman Omran
Published: October 2018

The fast development of computing multimedia has led to the demand of using digital images. The manipulation, storage and transmission of these images in their raw form is very expensive, it significantly slows the transmission and makes storage costly. In this paper, a brief review of wavelet transform theory is given using filters as examples to show the related multiresolution analysis. Advantages over Fourier transform is investigated and several results are derived. The pyramid algorithm is also presented and some features of wavelets in image data compression are given. A modified version of Lind Boze and Gray (LBG) algorithm using Partial Search Partial Distortion (PSPD) is presented for coding the wavelet coefficients to speed up the codebook generation and the search required for nearest neighbour codevector of input image. The proposed scheme can save 70 - 80 % of the Vector Quantization (VQ) encoding time as compared to fully search VQ and reduced arithmetic complexity with less sacrificing performance.Key Words: Image compression, Wavelets transform, Vector qQuantization

Authors: Thamer A. Mohammed Suleyman A. Muyibi, Ahmed Hissein M Birima, , M. M. Noor Megat Johari
Published: October 2018

The present study involved the use of a model pilot scale water treatment plant to treat turbid surface water from a stream using processed Moringa oleifera seed with 25 % w/w oil extracted as primary coagulant. The water treatment plant was made up of four unit operations: coagulation, flocculation, sedimentation, and filtration (rapid sand filter). Test runs were carried out for three hours per run over a three-month period with turbidities ranging from 18 to 261 NTU. The turbidity, pH, and alkalinity as well as the filter head loss were measured every 30 minutes during the experimental runs. Average turbidity removal of up to 96 % at an effective doses of 20 and 30 mg/l of oil extracted M. oleifera for low (< 50 NTU) and moderate turbidity (< 100 NTU) water respectively was observed doses 50 – 80 mg/l for high turbidity (> 100 NTU) water. M. oleifera seed extract was found to have no significant effect on pH or alkalinity of the water. The residual turbidities measured during most of the test runs satisfied the Malaysian Guideline for Drinking Water Supplies. Key Words: Moringa oleifera, primary coagulant, coagulation, pilot plant, filtration.
Comprehensive Downtime Prediction in Next-Generation Internet
Authors: S. Al-Irhayim, and K. A. Al-Khateeb W. F. Al-Khateeb,
Published: October 2018

The benchmark for the reliability quality of networks depends mainly on the accuracy and comprehensiveness of the reliability parameters. Downtime prediction of a communication system is crucial for the quality of service (QoS) offered to the end-user. Markov model enables analytical calculation of average single figure cumulative downtime over one year. The single average approach, generally, does not adequately describe the wide range of service performance that is likely to be experienced in communications systems due to the random nature of the failure. Therefore, it would be more appropriate to add downtime distribution obtained from network availability models to predict the expected cumulative downtime and other performance parameters among a large number of system populations. The distribution approach provides more comprehensive information about the behavior of the individual systems. Laplace-Stieltjes transform enables analytical solutions for simple network architectures, i.e. the simplex system and the parallel system. This paper uses simulations to determine reliability parameters for complex architecture such as the Multiprotocol Label Switching (MPLS) backbone planned for next-generation Internet. In addition to the single figure downtime, simulations provide other reliability parameters such as probability of zero downtime. The paper also considers the downtime distribution among a population of equally designed systems.Key Words: Reliability, availability, downtime, Multiprotocol label switching
Anti-Windup Scheme for Practical Control of Positioning Systems
Authors: Tarig Faisal and Abdulgani Albagul Wahyudi
Published: October 2018

Positioning systems generally need a good controller to achieve high accuracy, fast response and robustness. In addition, ease of controller design and simplicity of controller structure are very important for practical application.  For satisfying these requirements, nominal characteristic trajectory following controller (NCTF) has been proposed as a practical point-to-point (PTP) positioning control. However, the effect of actuator saturation can not be completely compensated for due to the integrator windup as the plant parameters vary. This paper presents a method to improve the NCTF controller for overcoming the problem of integrator windup using simple and classical tracking anti-windup scheme. The improved NCTF controller is evaluated through simulation using a rotary positioning system. The results show that the improved NCTF controller is adequate to compensate for the effect of integrator windup. Keywords: Positioning, point-to-point, integrator windup, compensation, controller, robustness.

The esterification of palmitic acid with methanol was studied in a batch reactor using macro porous ion exchange resin Amberlyst 15 as a catalyst. Methyl palmitate was produced from the reaction between palmitic acid and methanol in the presence of catalyst. The effects of processing parameters, molar ratio of alcohol to acid M, (4-10), catalyst loading (0-10 g cat/liter), water inhibition (0-2 mol/liter), agitator speed (200-800 rpm) and reaction temperature (343-373K) were studied. The experimental kinetic data were correlated using homogenous as well as heterogeneous models (based on single as well as dual site mechanisms). The activation energy of the reaction was 11.552 kJ/mol for forward reaction whilst 5.464 kJ/mol for backward reaction. The experimental data fitted well with the simulated data obtained from the kinetic models. Keywords: Palmitic Acid, Methanol, Esterification, Ion Exchange Resin, Kinetics.
Biotransformation of Domestic Wastewater Treatment Plant Sludge by Two-Stage Integrated Processes -Lsb & Ssb
Authors: A. H. Molla and A. Fakhruâ€™l-Razi Md. Zahangir Alam,
Published: October 2018

The study of biotransformation of domestic wastewater treatment plant (DWTP) sludge was conducted in laboratory-scale by two-stage integrated process i.e. liquid state bioconversion (LSB) and solid state bioconversion (SSB) processes. The liquid wastewater sludge [4% w/w of total suspended solids (TSS)] was treated by mixed filamentous fungi Penicillium corylophilum and Aspergillus niger, isolated, screened and mixed cultured in terms of their higher biodegradation potential to wastewater sludge. The biosolids was increased to about 10% w/w. Conversely, the soluble [i.e. Total dissolve solid (TDS)] and insoluble substances (TSS) in treated supernatant were decreased effectively in the LSB process. In the developed LSB process, 93.8 g kg-1of biosolids were enriched with fungal biomass protein and nutrients (NPK), and 98.8% of TSS, 98.2% of TDS, 97.3% of turbidity, 80.2% of soluble protein, 98.8% of reducing sugar and 92.7% of chemical oxygen demand (COD) in treated sludge supernatant were removed after 8 days of treatment. Specific resistance to filtration (1.39x1012 m/kg) was decreased tremendously by the microbial treatment of DWTP sludge after 6 days of fermentation. The treated biosolids in DWTP sludge was considered as pretreated resource materials for composting and converted into compost by SSB process. The SSB process was evaluated for composting by monitoring the microbial growth and its subsequent roles in biodegradation in composting bin (CB). The process was conducted using two mixed fungal cultures, Trichoderma harzianum with Phanerochaete chrysosporium 2094 and (T/P) and T. harzianum and Mucor hiemalis (T/M); and two bulking materials, sawdust (SD) and rice straw (RS). The most encouraging results of microbial growth and subsequent solid state bioconversion were exhibited in the RS than the SD. Significant decrease of the C/N ratio and germination index (GI) were attained as well as the higher value of glucosamine was exhibited in compost; which clearly implied that the increased bioconversion occurred in the treated process. Comparatively, superior composts were produced by T/P at 50-60 days of SSB. Significantly lower heavy metals (Pb, Cd, Cr, Ni, Cu and Zn) were recorded in chemical analysis of the end products (composts) after SSB, in comparison to the USA’s recognized limits for application in municipal solid waste (MSW).Keywords: Liquid state bioconversion, solid state bioconversion, domestic wastewater sludge, filamentous fungi, biosolids and compost.

The on board timer of AT89C52 is utilized to generate programmed clock for the scanning binary counter. The overall design is hardware minimized and compact that makes it feasible for low cost high performance ac drive applications.  The proposed PWM controller supports variable frequency variable voltage operation for wide range and hence is ideally suited for industrial drives requiring wide speed variations.  Keywords: Pulse width modulation, Microcontroller application, Voltage source inverter, variable speed ac drives.
Mems Electromagnetic Micro Relays Overview and Design Considerations
Authors: Thurai Vinay and Dinesh Sood Zuraini Dahari,
Published: October 2018

Miniature electromagnetic relay matrices capable of switching currents up to one ampere range are  widely used in commercial applications such as instrumentation and telecommunication. Traditionally these devices have been fabricated from a number of discrete components, however in recent years the emergence of Micro Electro Mechanical System (MEMS) technology has opened up the possibility for batch fabrication of microrelays at much reduced unit cost. While several electromagnetic microrelay designs have been successfully developed and commercialized for use as individual units, development work on electromagnetic microrelay matrices where individual relays can be selectively switched on and off have been fewer and less successful. Due to inherent limitations of the micromachining processes, significant dimensional and material property variations occur among individual relays in a matrix. These variations severely limit the tolerance window and hence the reliability of operation of the device. After reviewing existing designs of electromagnetic microrelays, a set of desirable design features that would make the electromagnetic microrelay more robust are identified.  A novel design incorporating these features is proposed and preliminary results of ANSYS1 simulation studies are presented.Keywords: MEMS, microrelay and electromagnetic
Thermal Shock In Periodic Edge-Cracked Plate Supported By Elastic Foundation
Authors: A. Rizk Abd El-Fattah
Published: October 2018

The study of the transient thermal stress problem for a periodic edge cracks in an elastic plate on an elastic foundations is investigated. This study may also be applied for circumferentially periodic cracked hollow cylinder under transient thermal stresses. Based on previous studies, the cylindrical shell may be modeled by a plate on an elastic foundation. The thermal stresses are generated due to sudden convective cooling on the boundary containing the edge cracks while the other boundary is insulated. The superposition technique is utilized to solve the problem. The perturbation problem is formulated by using the thermal stresses obtained from uncracked problem with opposite sign on the crack surfaces as the only external loading. This leads to hypersingular integral equation with the crack surface displacement as the only unknown function. The main output of this study is the transient stress intensity factors that are evaluated numerically. The parametric studies based on time (Fourier number), crack length, coefficient of heat transfer (Biot number), Periodic crack spacing and the stiffness of elastic foundation are investigated. Keywords: Fracture mechanics, Thermal stresses, Periodic crack, Stress intensity  factor.

Authors: OTHMAN M.R , LEE O E , FERNANDO W.J.N
Published: October 2018

The flow of O2, H2 and CO2 was in transition regime at relatively lower ΔT and then became turbulent at relatively higher ΔT when passed through the 5Å microporous zeolite adsorbent. Adsorption and surface diffusivity of all the gases that are being studied in these regimes increased with increase in ΔT. For the temperature difference from 5 to 115 K, the range of adsorption of O2 was between 6.319?10-12 and 5.762?10-11 kg/s. The adsorption of H2 was between 4.4?10-13 and 3.88?10-12 kg/s for the temperature difference ranging from 1 to 20 K. The adsorption of CO2 was between 5.3?10-12 and 4.9?10-11 kg/s for the temperature difference ranging from 5 to 100 K. At pressure of 1 bar, CO2 adsorption was the highest at all ΔT, followed by O2 and H2. The surface diffusivity increases with increase in ΔT. At a particular ΔT, the diffusivity increases asymptotically regardless of the flow regions.

Authors: Mohan N.S. , Kulkarni S.M. , Ramachandra A.
Published: October 2018

Polymer-based composite material possesses superior properties such as high strength-to-weight ratio, stiffness-to-weight ratio and good corrosive resistance and therefore, is attractive for high performance applications such as in aerospace, defense and sport goods industries. Drilling is one of the indispensable methods for building products with composite panels. Surface quality and dimensional accuracy play an important role in the performance of a machined component. In machining processes, however, the quality of the component is greatly influenced by the cutting conditions, tool geometry, tool material, machining process, chip formation, work piece material, tool wear and vibration during cutting. Drilling tests were conducted on glass fiber reinforced plastic composite [GFRP] laminates using an instrumented CNC milling center. A series of experiments are conducted using TRIAC VMC CNC machining center to correlate the cutting parameters and material parameters on the cutting thrust, torque and surface roughness. The measured results were collected and analyzed with the help of the commercial software packages MINITAB14 and Taly Profile. The surface roughness of the drilled holes was measured using Rank Taylor Hobson Surtronic 3+ instrument. The method could be useful in predicting thrust, torque and surface roughness parameters as a function of process variables. The main objective is to optimize the process parameters to achieve low cutting thrust, torque and good surface roughness. From the analysis it is evident that among all the significant parameters, speed and drill size have significant influence cutting thrust and drill size and specimen thickness on the torque and surface roughness. It was also found that feed rate does not have significant influence on the characteristic output of the drilling process.

Published: October 2018

Artificial neural networks have been shown to be able to approximate any continuous non-linear functions and have been used to build data base empirical models for non-linear processes. In this study, neural networks models were used to model the daily river flows or discharged in Langat River, Malaysia. Two possible ways of modelling were implemented which is by time series prediction and by the dynamics function of the system which include the past value of the discharged and also the rainfall in the input. The sum square error (SSE), residue analysis and correlation coefficient based on the observed and prediction output is chosen as the criteria of selection of which models is appropriate. It was found that the developed neural networks models using dynamics function provided satisfactory model discharges.

Authors: Abdullah A.Z. , Abu Bakar M.Z. , Bhatia S.
Published: October 2018

The performance of chromium (Cr) and copper (Cu) on silicon tetrachloride modified H-ZSM-5 (SiCl4-Z) catalyst in VOC combustion is reported. H-ZSM-5, modified with SiCl4 at 500?C for 3 h was impregnated with 1.0 wt. % of Cr and 0.5 wt. % of Cu. Performance studies were carried out at GHSV of 3,800 to 32,000 h-1 with 2,000 to 35,000 ppm of VOC. Changes in the activity of Cr-Cu/ SiCl4-Z were ascribed to extra framework deposits, surface acidity and pore characteristics. Cr-Cu/SiCl4-Z catalyst was more stable to coking, humidity and HCl than Cr-Cu/Z. In the combustion of chlorinated VOC, the chlorination of metal species deactivated the catalyst by rendering lower redox ability.

An Efficient Tasks Scheduling Algorithm for Distributed Memory Machines With Communication Delays
Authors: Abd El-Sattar Omara Fatma
Published: October 2018

The scheduling of multiple interacting tasks of a single parallel program is considered the most important issue to exploit the true performance of the multiprocessor system. The problem is to find a schedule that will minimize the execution time (Make_Span) of a program. On the other hand, task scheduling on a multiprocessor system with and without communication delays is known to be NP-complete problem. Consequently, many heuristic algorithms have been developed, each of which may find optimal scheduling under different circumstances. One of the well known iterative algorithms is the hill-climbing. This algorithm starts with a complete solution and searches to improve this solution by choosing a better neighbor based on a cost function. This will lead to a local optimum which is considered the main drawback of this algorithm. The research in this study concerns to develop an efficient iterative algorithm for scheduling problem based on the hill-climbing. Present algorithm satisfies a local optimum that is very close to the global one in a reasonable amount of time. In most experiments, it satisfies the actual global optimum.

Pity Silenced
Authors: Marzola Alessandra
Published: October 2018

While the mercantile value of mercy in The Merchant of Venice has been often highlighted, the diminished role of pity has received scant attention. This article argues that the ways in which mercy is shown to subsume and eventually incorporate pity throw light on the play’s negotiation of contentious religious and political approaches to the spectres of poverty and/or impoverishment that threaten the emerging mercantile economy. A re-reading of relevant scenes retraces the Catholic implications of the safety-net potential of pity which, unlike the Protestant worldly pity of The Sonnets, here seems bound for repression. In Portia’s final donation to the merchants of Venice even the lingering allusions to Catholicism are neutralized and put to the service of vested interests: a conflation of Christian and Jewish usury that cuts across all religious divides; such allusions are possibly reminiscent of the Monti di Pietà (Mounts of Piety) existent in Italy since 1462 to counter Jewish usury.
‘Love Merchandized’
Authors: Pfister Manfred
Published: October 2018

Although analysing Shakespeare’s sonnets in the context of ‘Shakespeare and money’ is not an obvious choice, I believe that Karl Marx’s ‘The Power of Money’ in his Economic and Philosophic Manuscripts are as relevant to the sonnets as they are to plays such as Timon of Athens. My reading of them will foreground their dialogue with terms and developments in early modern banking and focus on metaphors of economic transaction that run through the whole cycle; indeed, a third of them figure love, its wealth and truth, use and abuse, in terms of investment in order to project an alternative economy beyond the self-alienating world of banking/financial gain. This imbrication of the erotic with the economic comprises also the writing of love sonnets, a competitive game-like economic transaction. Soneteering is a way of ‘merchandizing love’ that inevitably casts a capitalist shadow across the supposedly most sincere expression of love.
Biography and Shakespeare’s Money
Authors: Pugliatti Paola
Published: October 2018

Robert Bearman’s book Shakespeare’s Money (2016) can be considered the
first economic biography of William Shakespeare; but it is also the latest
specimen of an innovative trend in Shakespeare biography which has come
to the fore over the last ten years or so. While the vein of cradle-to-grave
biographies seems to be exhausted, new attention is being devoted to parts
of Shakespeare’s life, with an attitude that has been seen as ‘microhistorical’
or ‘disintegrationist’. The article will discuss this new kind of sensitivity to
biography in general and Shakespeare biography in particular. It starts out
by addressing certain developments in the theory and practice of life writing
during the second half of the twentieth century, which are today becoming
ever more substantial; it then examines the progress of Shakespeare
biographies and, in particular, how the issue of money has been tackled
since Nicolas Rowe first dealt with it.
Shakespeare and Derivatives
Authors: Hawkes David
Published: October 2018

The twenty-first century has witnessed the rise to power of images in every aspect of human endeavour. Speculative financial derivatives have achieved a predominant place in the economy, spin and perception rule the political sphere, and technological media ensure that we spend our lives surrounded by images of all kinds. Reading the works of Shakespeare reveals the roots of this process in the early modern period, when the iconoclasm of the Reformation, popular protests against usury, and the campaign against ritual magic combined to provide an ethically based popular resistance to the power of signs.
Hamlet’s Catch-22
Authors: Azad Bahareh , Abbasi Pyeaam
Published: October 2018

The double-bind dilemma that Hamlet is engulfed in places him in a catch-22 situation from which there seems to be no way out. Locked in a psychological impasse exacerbated by a deficient Oedipal process due to the father’s death and mother’s remarriage, he is driven into (feigning) insanity, a situation that brings him close to Yossarian, Heller’s paranoid antihero who is as much inept in the face of the paternalistic ordeal he is subjected to as an army fighter. Evading the fear of castration on the one hand and becoming consumed with guilt for the incompetence to face the trial on the other give rise to problematic identities of both protagonists and numerous evasive strategies they plot. Nevertheless, through mainly linguistic/textual acts of defiance, these initially victimized subjects to the law of the father turn into rebels, mastering and thus making the Symbolic order backfire on itself.
Application of Evolutionary Algorithms for Modelling and Optimisation of Ultrasound-Related Parameters on Synthesised SAPO-34 Catalysts: Crystallinity and Particle Size

Published: October 2018

First, the effects of ultrasound-related variables on the crystallinity and particle size of synthesised SAPO-34 catalysts were modelled using a genetic programming (GP) method. The results confirm that GP has good predictive power. Secondly, optimisation of the ultrasound parameters was considered using a genetic algorithm (GA) to obtain SAPO-34 catalysts with high crystallinity and minimum particle size for the best performance in the methanol to light olefins process. The GP models were used as the fitness functions inside the GA. Finally, the optimum solution was validated experimentally and the results indicate that there is a good agreement between experimental and predicted values.

Published: October 2018

The activities of cobalt catalysts prepared by the microemulsion impregnation method on carbon nanotubes (CNTs) and functionalised carbon nanotubes (FCNTs) supports were evaluated in the Fischer–Tropsch synthesis (FTS). The catalysts were characterised by transmission electron microscopy, X-ray diffraction and Brunauer–Emmett–Teller surface area methods. The results show that the cobalt particles in the FCNTs support are mostly located inside the tubes of the CNTs and show a narrower particle size distribution. The experimental results show that the cobalt catalyst supported on FCNTs leads to a higher CO conversion and FTS activity compared to that supported on normal CNTs. Calculated kinetic results show that the activation energies fall within the narrow range of 101.1–107.1 kJ mol−1 and the heat of hydrogen adsorption was calculated to be −40.2 and −26.2 kJ mol−1 for Co/CNTs and Co/FCNTs catalysts respectively. FCNTs, as a catalyst support of Co nanoparticles, maintain high dispersion which can be attributed to a hydrogen spillover effect of functional groups on the CNT surface.

Published: October 2018

The synthesis and interactions of the cis-diaqua-chloro-tris(dimethyl sulfoxide)ruthenium(II) complex with selected sulfur-containing ligands such as 2-thiouracil, glutathione and L-cysteine have been studied by UV-Vis spectrophotometry in aqueous medium at pH 4.5. From experimental data it is clear that all three reactions proceed via two steps: the first one being a rate-limiting ligand-dependent replacement of one water molecule, followed by a ligand-independent ring closure step with the expulsion of the second water molecule. The substituted products have been characterised by Job's method, FTIR spectroscopy and electrospray ionisation mass spectrometry. Activation parameters (Δ H≠ and Δ S≠) and thermodynamic parameters (Δ H0 and Δ S0, from the temperature dependence of the outer-sphere association equilibrium constant) are presented. Consistent with the experimental findings, an associative interchange mechanism is proposed.

Philosophy and Philosophical Education in Kazimierz Twardowski’s Interpretation
Authors: Honcharenko Olga
Published: October 2018

Philosophy determination, its place and purpose in human life and society is the eternal philosophical problem. In this paper the reader is suggested to analyze the attempt of its solving by outstanding Polish philosopher Kazimierz Twardowski. Free from the extremes of metaphysics and minimalism, Kazimierz Twardowski’s philosophy has not only created the conditions for philosophical culture development, but has also brought up a pleiad of philosophically educated scientists. What are the peculiarities of Kazimierz Twardowski’s philosophy? On the bases of philosophical papers analysis, scientific and historical definition of the concept of philosophy has been carried out. It is proved, that the scientific concept of philosophy, as one of the components of polylogue manifestation of the human spirit, dissolves in historical concept of philosophy. Such philosophy understandingbrought the philosopher to the conclusion about vital human and social necessity in philosophy. If a man and society do not feel the necessity in philosophy, due to the lack of their spiritual culture, this necessity should be grown. Therefore, the care about philosophical education was one of the main goals of Twardowski’s life. The scientist interpreted philosophical education as a part of general education. He determined philosophy studies as a way of life and a school of thinking. Due to this, Twardowski believed that method studying as natural means of knowledge and self-cognition is a humane act promoting creating man’s own view of the world. Special understanding of the philosophy and the background of its development – philosophical education by talented scientist and teacher – encourages reflection on the problems in the field of Ukrainian philosophy. Philosophical and pedagogical understanding of Twardowski’s experience is relevant in the context of increasing complexity of modern relationships between a man and society.
Women, Education and Employment in Saudi Arabia: an Example of Multiple Modernities
Authors: Fadaak Talha , Roberts Ken
Published: October 2018

This paper uses official statistics and previous research by Saudi scholars, but mainly our own evidence from 23 interviews during 2015 and 2016 with 25-35-year-old males and females, to explain why modernisation is Saudi Arabia, which includes the diversification of its economy and a huge expansion in higher education for males and females, is unlikely to lead to a higher proportion of women in the workforce. This is because the total number of jobs in the country is unlikely to increase, and opportunities for women are likely to remain limited not only by employers’ hiring preferences and practices but also by the limited range of jobs that young women and their families consider acceptable. Thus rather than following the same modernizing path as Western societies, Saudi Arabia will add to the examples of multiple modernities.

The refusal of food in the elderly patient: identification of the causes of rejection of the meal in senior age and hypotheses of intervention to prevent, treat and rehabilitate malnutrition
Authors: Seccafien Giacomo
Published: October 2018

Malnutrition can derive from causes that are independent of the patient's desire to feed themselves or which manifest themselves with the refusal of the meal; while for the former the strategies for solving and compensating the problem are more predictable, for the latter it is not always easy to have effective and prompt intervention procedures available.
The importance of a method that investigates the causes of food refusal and provides rehabilitative pathways to accepting the meal, designed to intervene on fasting in a structured way, lies in the timeliness and clarity of the roles.
I.R.M.I.E. (Investigation of the Rejection of Meal in the Institutional Elderly) analyzes the refusal of the meal and the consequent malnutrition linked to it, in the elderly subject institutionalized and not. It is thought of as a trace to identify the causes that lead the fasting patient to a condition of vital risk and to propose strategies of compensation and resolution to the problem. It is the premise of an individualized plan. It should be discussed as a team in the case and also given to the family member by the same or alternatively by a professional elected to the role, with a subsequent comparison. The planning of an intervention plan will follow, according to the procedures proposed in the manual that includes it, related to the identified causes, and of the resources exploitable in the service.

Method of finite element modeling was used for mathematic modeling of pelvic fractures and various variants of anterior and posterior pelvic ring fixation with reconstructive plates, cannu- lated sacroiliac screws and pelvic screws. Four most common types of fracture were simulated. Stress-deformed conditions of metal constructions for every type of fracture and variant of its fixation were determined. Study results enabled to determine the optimum fixation techniques in various types of fractures, to confirm the significance of both anterior and posterior pelvic stabilization, as well as to substantiate the possibility of early rehabilitation with full weight bearing in such severe patients
