The Minangkabau Rabab Pasisia: Music, Performance and Practice in West Sumatra Indonesia
No full textThis study is a detailed examination of the instrument known as rabab Pasisia Selatan and its performance among the Minangkabau, who are the dominant ethnic group in West Sumatra, Indonesia. It is the first study of its kind in English and compliments two unpublished studies on the topic in Bahasa Indonesia.
Although played on an instrument with the appearance of a violin, the music is indigenous to Minangkabau with characteristics shared by other local genres. It is played in a cross-bowed position in the manner of other Indonesian rebab "spiked fiddles" of which there are many variants. Chapter 1.
The formulation of adat (encapsulating both the Minangkabau worldview and specifics of polity) is examined and found to be key to understanding the creativity of the tukang rabab and the context of musical performances. Adat formulation is characteristically oral and based on discussion and consensus, which affords the resulting decision flexibility and local resonance. The high value placed on localisation has been propagated as an ideal in Minangkabau adat and this ethos extends to the creative attitudes of rabab Pasisia performers. Chapter 2.
This study uses a performance-based approach, drawing on the experiences of the author as a pupil and performer of the rabab Pasisia and documentation from professional players. Fieldwork methods, which combine the observation of music and the process of performing, are investigated in Chapter 3.
Players of the rabab Pasisia are professional musicians hired to celebrate important life-cycle events such as weddings and circumcisions. During all-night performances the male rabab Pasisia player accompanies himself singing poetry (pantun) and extended narrative (kaba). A typical ensemble consists of a lead rabab player (responsible for the kaba) and two or three supporting singers, who bebelas pantun (swap poetry) to the accompaniment of a small frame drum. Chapter 4 looks at the events and settings in which the music is performed, including the process of organising a performance, from the moment that the player is hired, through to post-performance.
The dynamics, aesthetics and creative processes involved in rabab Pasisia performance is explored in Chapters 5-8. Approaches to the transmission of both the verbal and musical elements in this totally oral art form are also examined. With regard to the words the creation of pantun (poetry) in performance is examined, as is the development of a full kaba. Examples of four kaba performances have been transcribed in the Minangkabau language and translated into English, with recordings included on the accompanying compact Disks.
With regard to both the words and the music the pervasive aesthetic is one of recreation, as players prefer not to perform the music the same way each time. The repertoire, however, remains recognisable to the audience because of certain performance conventions. The fluidity/fixity of elements in rabab Pasisia performance are explored, with the help of transcriptions and musical example with a focus on the gelitik which are the rapid, repeated motives played on the rabab, the linking together of which creates a melody line
Accurate Classification of Cervical Cancer Based on Multi-layer Perceptron Hunger Games search Optimization technique
No full textCancer is distinguished by the presence of abnormal cellular proliferation and growth, both of which serve as signs and symptoms for this kind of illness. Computer vision, deep learning, and metaheuristics optimization techniques are increasingly important for solving complex medical Artificial Intelligence (AI) problems such as cancer detection. This paper introduces a new methodology for training the Multi-Layer Perceptron (MLP) using the optimization algorithm known as Hunger Games search Optimization technique (HGO) and apply this method to classify the cervical cancer. The main goal of this method is to reduce the error and enhance the classification rate of cervical cancer. The outcomes show that the MLP with HGO algorithm performed better than other algorithms in terms of classification efficacy and accuracy rate. Simulation outcomes indicate that the proposed strategy performs better than previously published research in terms of effectiveness for the classification optimization methods

The effect of poling state, surface charge, and frequency of vibration of piezoelectric poly (vinylidene fluoride) films for bone and neural tissue engineering applications
No full textNovel paradigms for tissue engineering recognize the need for active or smart scaffolds in order to properly regenerate specific tissues. Electrical and electromechanical cues are the most relevant in promoting functionality in tissues such as nerve, muscle, and bone, among others. The existence of electrical phenomena within certain tissues may suggest the requirement of such phenomena (ie., electroactivity, piezoelectricity) during tissue regeneration. For instance, it has been shown that electrically charged surfaces can influence different aspects of cell behavior such as growth, adhesion, or morphology of different cell types, including osteoblast, neural, and muscular cells. Therefore, electroactive materials and, in particular, piezoelectric ones, show a strong potential for novel tissue engineering strategies. Piezoelectric materials have an interesting ability to vary surface charge when a mechanical load is applied, without the need for an external power source or connection wires, a feature that can be taken advantage of in novel tissue engineering strategies. Poly (vinylidene fluoride) (PVDF) is a semi-crystalline and biocompatible polymer with the largest piezoelectric response among piezoelectric polymers, mechanical properties appropriate for tissue engineering applications, and excellent electroactive properties such as piezo-, pyro and ferroelectricity. It was hypothesized that by varying vibration frequencies in piezoelectric substrates, attached neuronal cells would respond with varying onsets of growth.
Since nerves innervate both bones and muscles, we further hypothesized that frequencies that promoted neural growth would also promote bone and muscle cell growth. The first aim of this study sought to investigate the effect of oscillating electric fields on a variety of mesenchymal tissues—human mesenchymal stem cells (hMSCs), bone (osteoblasts), and nerve cells by seeding them on poled and unpoled PVDF membranes and vibrating them at 20, 60, and 100 Hz. The results of this study indicated significant increases in osteogenic activity for both osteoblasts and hMSCs when subjected to mechanical vibration and the piezoelectric effect. Metabolic activity assays of hMSCs and osteoblasts verified that proliferation of both cell types was enhanced due to the piezoelectric effect of poled PVDF films but reduced in response to mechanical stimulation alone. Neurite imaging of undifferentiated and differentiated nerve cells revealed increases in neurite growth in response to mechanical and electrical stimulation.
Bone is itself piezoelectric, it follows that bone cells would respond to piezoelectric substrates. Nerves also come into direct contact with bone, thus it follows that the piezoelectric properties of bone also affect nerve cells. Therefore, the second hypothesis is that piezoelectric substrates with a surface charge most mimicking that of bone will promote increased adhesion and proliferation of bone and nerve cells. Thus, on the second aim of this dissertation is to examine the effect of stationary electric fields on a variety of mesenchymal tissues—human mesenchymal stem cells (hMSCs), bone, and nerve cells by seeding them on tissue culture polystyrene and three kinds of PVDF film surfaces: unpoled films with no surface charge, poled films with cells cultured on the positively charged side of the sample, and poled films with cells cultured on the negatively charged side of the sample. The same methods that were used in investigating the effect of oscillating electric fields on cells were employed to observe how the stationary electric field affects cells differentiation and growth and at the same time points. The results showed a more homogeneous distribution of hMSCs and osteoblasts seeded on negatively poled PVDF films, but no osteogenesis. Metabolic activity assays of hMSCs and osteoblasts indicated that the highest number of viable hMSCs resulted on negatively poled PVDF films while the highest number of viable osteoblasts occurred on positively poled PVDF films. Finally, neurite imaging verified that charged piezoelectric PVDF membranes induce neurite outgrowth more than electrically neutral membranes in the absence of electrical stimulation.
The final goal of this study was to fully characterize the dynamics of the loading environment cells were subjected to, which has not been previously reported in PVDF cell studies, and to correlate the measurements to cell fate. Directly measuring PVDF and media displacement permitted calculation of the actual acceleration PVDF and cells were subjected to and illustrated that the cell culture media has a significant impact on the oscillating pressure imparted to the films and thus the piezoelectric output of the PVDF. From these measurements, it was possible to estimate the voltage output of the PVDF films, which for 100 Hz vibrations were in the physiological range of the action potentials that are experienced by excitable cells such as muscle and nerve. These results suggest a cause for the observed change in morphology of hMSCs towards neuronal cells. The results from this study may better define optimal stimulation parameters for desired cell fate and has already resulted in unexpected and new findings not yet reported in the literature.Ph.D.Includes bibliographical referencesby Rabab Chalab

This message underscores the imperative toremain steadfastly connected to one’s homeland, regardless of prevailingcircumstances and notwithstanding the severity of the conditions at hand.
As for the form, discontinuity was we found in the chronological order in thetwo novels, so it was clear that the plot has dismantle the event into complexand overlapping subplots, which confirms the writer’s openness to new literaryforms and methods
Nutritional knowledge following interventional educational sessions in children on regular hemodialysis
No full textTo evaluate the impact of nutritional knowledge following interventional educational sessions in chronic dialysis patients, we studied 40 children on chronic regular hemodialysis (HD) at the beginning and after six months of nutrition educational sessions using a predesigned questionnaire. We also measured the anthropometric parameters of nutrition to evaluate the impact of this education on the health of patients. We found a highly statistically significant increase in patients′ scores and in adequate knowledge using the questionnaire after the educational sessions. Our results showed a statistically significant decrease in body mass index and weight after educational sessions for six months. Moreover, there were no significant decreases in serum phosphorus, ferritin, iron and creatinine, in contrast with no significant increase in hemoglobin, serum calcium, blood urea nitrogen and serum albumin. We conclude that nutritional education is significantly effective with regard to the level of knowledge, but not with regard to the attitude and practice in children on chronic HD
Heterologous Expression of the Barley (Hordeum vulgare L.) Xantha-f, -g and -h Genes that Encode Magnesium Chelatase Subunits
No full textBiosynthesis of chlorophyll involves several enzymatic reactions of which many are shared with the heme biosynthesis pathway. Magnesium chelatase is the first specific enzyme in the chlorophyll pathway. It catalyzes the formation of Mg-protoporphyrin IX from the insertion of Mg2+ into protoporphyrin IX. The enzyme consists of three subunits encoded by three genes. The three genes are named Xantha-h, Xantha-g and Xantha-f in barley (Hordeum vulgare L.). The products of the genes have a molecular weight of 38, 78 and 148 kDa, respectively, as mature proteins in the chloroplast. Most studies on magnesium chelatase enzymes have been performed using recombinant proteins of Rhodobacter capsulatus, Synechocystis sp. PCC6803 and Thermosynechococcus elongatus, which are photosynthetic bacteria. In the present study we established a recombinant expression system for barley magnesium chelatase with the long-term goal to obtain structural information of this enigmatic enzyme complex from a higher plant. The genes Xantha-h, -g and -f were cloned in plasmid pET15b, which allowed the production of the three subunits as His-tagged proteins in Escherichia coli BL21(DE3)pLysS. The purified subunits stimulated magnesium chelatase activity of barley plastid extracts and produced activity in assays with only recombinant proteins. In preparation for future structural analyses of the barley magnesium chelatase, stability tests were performed on the subunits and activity assays were screened to find an optimal buffer system and pH
