description: We perform microscopic molecular dynamics simulations of particle chains with an onsite anharmonicity to study relaxation of spatially homogeneous states to equilibrium, and directly compare the simulations with the corresponding Boltzmann-Peierls kinetic theory. The Wigner function serves as common interface between the microscopic and kinetic level. We demonstrate quantitative agreement after an initial transient time interval. In particular, besides energy conservation, we observe the additional quasi-conservation of the phonon density, defined via an ensemble average of the related microscopic field variables and exactly conserved by the kinetic equations. On super-kinetic time scales, density quasi-conservation is lost while energy remains conserved, and we find evidence for eventual relaxation of the density to its canonical ensemble value. However, the precise mechanism remains unknown and is not captured by the Boltzmann-Peierls equations.

description: The $\rm{H}α$-to-UV luminosity ratio ($L(\rm Hα)/L(\rm UV)$) is often used to probe SFHs of star-forming galaxies and it is important to validate it against other proxies for burstiness. To address this issue, we present a statistical analysis of the resolved distribution of $Σ_{\rm{SFR}}$ as well as stellar age and their correlations with the globally measured $L(\rm Hα)/L(\rm UV)$ for a sample of 310 star-forming galaxies in two redshift bins of $1.37 < z < 1.70$ and $ 2.09 < z < 2.61$ observed by the MOSDEF survey. We use the multi-waveband CANDELS/3D-HST imaging of MOSDEF galaxies to construct $Σ_{\rm{SFR}}$ and stellar age maps. We analyze the composite rest-frame far-UV spectra of a subsample of MOSDEF targets obtained by the Keck/LRIS, which includes 124 star-forming galaxies (MOSDEF-LRIS) at redshifts $1.4 < z < 2.6$, to examine the average stellar population properties, and the strength of age-sensitive FUV spectral features in bins of $L(\rm Hα)/L(\rm UV)$. Our results show no significant evidence that individual galaxies with higher $L(\rm Hα)/L(\rm UV)$ are undergoing a burst of star formation based on the resolved distribution of $Σ_{\rm{SFR}}$ of individual star-forming galaxies. We segregate the sample into subsets with low and high $L(\rm Hα)/L(\rm UV)$. The high-$L(\rm Hα)/L(\rm UV)$ subset exhibits, on average, an age of $\log[\rm{Age/yr}]$ = 8.0, compared to $\log[\rm{Age/yr}]$ = 8.4 for the low-$L(\rm Hα)/L(\rm UV)$ galaxies, though the difference in age is significant at only the $2σ$ level. Furthermore, we find no variation in the strengths of Siiv$λ\lambda1393, 1402$ and Civ$λ\lambda1548, 1550$ P-Cygni features from massive stars between the two subsamples.

description: Codecs using spectral-spatial transforms efficiently compress raw camera images captured with a color filter array (CFA-sampled raw images) by changing their RGB color space into a decorrelated color space. This study describes two types of spectral-spatial transform, called extended Star-Tetrix transforms (XSTTs), and their edge-aware versions, called edge-aware XSTTs (EXSTTs), with no extra bits (side information) and little extra complexity. They are obtained by (i) extending the Star-Tetrix transform (STT), which is one of the latest spectral-spatial transforms, to a new version of our previously proposed wavelet-based spectral-spatial transform and a simpler version, (ii) considering that each 2-D predict step of the wavelet transform is a combination of two 1-D diagonal or horizontal-vertical transforms, and (iii) weighting the transforms along the edge directions in the images. Compared with XSTTs, the EXSTTs can decorrelate CFA-sampled raw images well: they reduce the difference in energy between the two green components by about $3.38$--$30.08$ \% for high-quality camera images and $8.97$--$14.47$ \% for mobile phone images. The experiments on JPEG 2000-based lossless and lossy compression of CFA-sampled raw images show better performance than conventional methods. For high-quality camera images, the XSTTs/EXSTTs produce results equal to or better than the conventional methods: especially for images with many edges, the type-I EXSTT improves them by about $0.03$--$0.19$ bpp in average lossless bitrate and the XSTTs improve them by about $0.16$--$0.96$ dB in average Bjøntegaard delta peak signal-to-noise ratio. For mobile phone images, our previous work perform the best, whereas the XSTTs/EXSTTs show similar trends to the case of high-quality camera images.

description: Background: Ewing’s (ES) sarcoma of the scapula is a rare entity. It is oftenly discovered late at the metastatic stage of the disease because of its deep location. This neoplasm is common in children and adolescents. We present the first reported case of a localized Ewing’s sarcoma of the scapula in an adult over 40 years-old. Case presentation: A 48-year-old man presents with left shoulder pain evolving for one year. Physical examination showed a painful, ill-defined swelling of the left shoulder measuring 5 x 3 cm. An MRI was performed showing a mass of the left scapula invading the soft tissues of the shoulder suggestive of a sarcoma. The patient underwent a surgical biopsy finding an Ewing's sarcoma of the scapula with no secondary localization on the CT scan nor on the bone scintigraphy. Neo-adjuvant multiagent chemotherapy was started obtaining a total response. Therefore, the patient underwent a total left scapulectomy. Histopathological examination confirmed the diagnosis of Ewing's sarcoma with a complete response to chemotherapy. Adjuvant chemotherapy was then indicated. After 3 years of follow-up, no local or distant recurrence was found. Clinical discussion: ES is a high-grade aggressive lesion that most commonly originates in bone. The ES may affect any bone but is frequent in femur, tibia and ilium, the tumors arising from the scapula comprise fewer than 4% of all ES. No cases of localized Ewing’s sarcoma in adults have been reported to our knowledge. The diagnosis is confirmed by immunohistochemical examination and cytogenic. Multimodal therapeutic approaches, which involve a combination of chemotherapy, surgery and radiation, yield modest improvements in outcome for localized tumors. Metastatic tumors still have poor diagnosis. Conclusion: ES occurs rarely in adults greater than 20 years-old, and tumors localized in the scapula are even rarer. Histopathology differentiates it from other primary bone/soft tissues tumors.

description: Motivated by uncertainty quantification in natural transport systems, we investigate an individual-based transport process involving particles undergoing a random walk along a line of point sinks whose strengths are themselves independent random variables. We assume particles are removed from the system via first-order kinetics. We analyse the system using a hierarchy of approaches when the sinks are sparsely distributed, including a stochastic homogenization approximation that yields explicit predictions for the extrinsic disorder in the stationary state due to sink strength fluctuations. The extrinsic noise induces long-range spatial correlations in the particle concentration, unlike fluctuations due to the intrinsic noise alone. Additionally, the mean concentration profile, averaged over both intrinsic and extrinsic noise, is elevated compared with the corresponding profile from a uniform sink distribution, showing that the classical homogenization approximation can be a biased estimator of the true mean.

description: Background: HIV/AIDS is known to be one of the most catastrophic diseases that have confronted humanity in living memory. Even though there are segments of disadvantaged social groups who are at risk HIV infection due to their lower level of socio economic capacity it is believed that people with disability are more vulnerable to HIV infection. Objective: To assess the risky sexual practices, accessibility and utilization of HIV service among people with disability in Addis Ababa City Administration. Materials and methods: Between September 2010 and April 2011, a cross sectional community based survey was conducted using interviewer administered questionnaire of 417 people with disabilities found from associations of people with disabilities in Addis Ababa City Administration. This was supplemented with focus group discussions with disabilities for access and utilization of HIV services. The findings were described and analyzed using SPSS version 16. Result: Based on the findings, more than half (60%) of study participants were sexually active and a third of them (28.4%) had initiated sex before 18 years. Almost half (48%) of these did not use condoms consistently and 33.6% had multiple sexual partners. Majority (92.8%) have information for existence of HIV services in the country. About 72% of all participants have ever utilized some kind of HIV services ever. Female respondents were nearly 2.5 times more likely to use condoms than males irrespective of type of disabilities [AOR (95%CI) 2.46 (1.28-4.71)]. Those ever married were 2.5 times more likely to use condoms than singles [AOR (95%CI) 2.54(1.49-4.35)]. Visually impaired participants are about 2 times more likely to have multiple sexual partners than those of physically impaired [AOR (95%CI) 1.90(1.02-3.55)]. In addition, those who were singles are 45% less likely to have multiple sexual partners than those of ever married [AOR (95%CI) 0.55(0.31- 0.97)]. Regarding utilization of HIV services, hearing impaired participants were about two times more likely to have utilized any HIV services than those of visual impaired [AOR (95%CI) 2.12(1.13-3.98)]. Conclusions: In general, the findings in this study showed poor access to information, less convenient of facilities and low utilization of HIV service among people with disabilities. Improving access to information on HIV through targeting PWDs, support to HIV service providers in developing disability sensitive communication materials and improving health service delivery systems to take care of disability are recommended.

description: We report a deterministic and exact protocol to reverse any unknown qubit-unitary operation, which simulates the time inversion of a closed qubit system. To avoid known no-go results on universal deterministic exact unitary inversion, we consider the most general class of protocols transforming unknown unitary operations within the quantum circuit model, where the input unitary operation is called multiple times in sequence and fixed quantum circuits are inserted between the calls. In the proposed protocol, the input qubit-unitary operation is called 4 times to achieve the inverse operation, and the output state in an auxiliary system can be reused as a catalyst state in another run of the unitary inversion. We also present the simplification of the semidefinite programming for searching the optimal deterministic unitary inversion protocol for an arbitrary dimension presented by M. T. Quintino and D. Ebler [Quantum $\textbf{6}$, 679 (2022)]. We show a method to reduce the large search space representing all possible protocols, which provides a useful tool for analyzing higher-order quantum transformations for unitary operations.

description: We study universal bosonic few-body systems within the framework of effective field theory at leading order (LO). We calculate binding energies of systems of up to six particles and the atom-dimer scattering length. Convergence to the limit of zero-range two- and three-body interactions is shown, indicating that no additional few-body interactions need to be introduced at LO. Generalizations of the Tjon line are constructed, showing correlations between few-body binding energies and the binding energy of the trimer, for a given dimer energy. As a specific example, we implement our theory for 4He atomic systems, and show that the results are in surprisingly good agreement with those of sophisticated 4He-4He potentials. Potential implications for the convergence of the EFT expansion are discussed.

description: Non-Fungible Token (NFT) is evolving with the rise of the cryptocurrency market and the development of blockchain techniques, which leads to an emerging NFT market that has become prosperous rapidly then followed by a cooldown. Nevertheless, the overall rise procedure of the NFT market has not been well understood. To this end, we consider that social media communities evolving alongside the market growth, are worth exploring and reasoning about, as the mineable information might unveil the market behaviors. We explore the procedure from the perspective of NFT Twitter communities and its impact on the NFT price moves with two experiments. We perform a Granger causality test on the number of tweets and the NFT price time series and find that the number of tweets has a positive impact on (Granger-causes) the price or reversely for larger part of the 19 top authentic projects but seldom copycat projects. Besides, to investigate the price moves predictability, we experiment on predicting Markov normalized NFT price (representing the direction and magnitude of price moves) given tweets-extracted word features and interpret the feature importance to find insights. Our results show that social media words as the predictors result in all 19 top projects having a testing accuracy evidently above the baseline. Based on the feature importance analysis, we find that both general market-related words and NFT event-related words have a markedly positive contribution in predicting price moves. We summarize the characteristics including categorization and sentiment for the words with the top and least feature importance.

description: We discuss different $\rm SU(5)$ low-energy realizations and illustrate their use with the diphoton excess and Higgs flavor violation, which require new physics at the TeV scale. In particular, we study two scenarios for a $750$ GeV resonance: in the first one the resonance belongs to the adjoint of $\rm SU(5)$, being either an $\rm SU(2)_L$ singlet or a triplet, while in the second case the signal is due to the CP-even and CP-odd states of a new $\rm SU(2)_L$ Higgs doublet belonging to a ${\bf 45}_H$ or a ${\bf 70}_H$ representations, giving rise to a two-Higgs doublet model at low energies. We study the fine-tuning needed for the desired members of the multiplets to be light enough, while having the rest at the GUT scale. In these scenarios, the production and decay into photons of the new resonance are mediated by the leptoquarks (LQ) present in these large $\rm SU(5)$ representations. We analyse the phenomenology of such scenarios, focusing on the most relevant predictions that can help to disentangle the different models, like decays into gauge bosons, Standard Model (SM) fermions and LQs pair production. In the case of the ${\bf 45}_H$ (the Georgi-Jarlskog model), we also study the possibility to have Higgs flavor violation. We find that $B_s$ mixing limits (in addition to $τ\rightarrow μγ$) always imply that $\rm{BR}(h\rightarrow τμ,\,bs)\lesssim 10^{-5}$.

description: Agricultural intensification has caused decrease and fragmentation of European semi-natural dry grasslands. While a high biodiversity value of dry grasslands is acknowledged for plants and insects, locally and on landscape level, their relevance for mobile species, such as bats, is unknown. Here we investigate the use of dry grassland fragments by bats in an agriculturally intensified region in Germany and evaluate local and landscape factors influencing bat activity and assemblages. Specifically, we predicted that a combination of local dry grassland structural richness and landscape features as well as their interactions affect bat activity and foraging above dry grasslands. We also expected that these features influence compositions of local bat assemblages. We repeatedly sampled at 12 dry grassland plots with acoustic monitoring and assessed activity and foraging of bat species/sonotypes, which we grouped into guilds known for foraging in open land, at vegetation edges and in narrow spaces. We determined structural richness of the dry grassland plots in field and derived landscape features from digital landscape data. A relatively high proportion of bat species/sonotypes used dry grasslands regularly. The edge space foragers responded positively to higher local structural richness. Their dry grassland use increased when surrounding forests and woody features were less available, but they foraged more on dry grasslands closer to water bodies. Narrow space bat activity on dry grasslands decreased with less landscape connectivity. Open and narrow space foragers responded to local structural richness only in landscape context. For all bat guilds we found increased use of structurally richer dry grasslands when there was more open farmland in the surroundings. This was also the case for edge space foragers, when landscapes were more homogeneous. Lastly, with increasing structural richness, bat assemblages were more dominated by edge space foragers. We show the importance of European dry grassland fragments for the highly mobile group of bats under certain local structural and landscape compositional conditions. Our results underline the value of heterogeneous dry grassland fragments as potential stepping stones in intensively used farmland areas and contribute to evidence based decision making in dry grassland management and bat conservation.

Our theoretical framework is a Nambu-Jona-Lasinio model with a contact interaction. Within this model we compute the critical temperature of chiral symmetry restoration, $T_c$, as a function of the chiral chemical potential and field strengths. We find that the fields inhibit and $μ_5$ enhances chiral symmetry breaking, in agreement with previous studies.

description: Quantum machine learning (QML) networks promise to have some computational (or quantum) advantage for classifying supervised datasets (e.g., satellite images) over some conventional deep learning (DL) techniques due to their expressive power via their local effective dimension. There are, however, two main challenges regardless of the promised quantum advantage: 1) Currently available quantum bits (qubits) are very small in number, while real-world datasets are characterized by hundreds of high-dimensional elements (i.e., features). Additionally, there is not a single unified approach for embedding real-world high-dimensional datasets in a limited number of qubits. 2) Some real-world datasets are too small for training intricate QML networks. Hence, to tackle these two challenges for benchmarking and validating QML networks on real-world, small, and high-dimensional datasets in one-go, we employ quantum transfer learning composed of a multi-qubit QML network, and a very deep convolutional network (a with VGG16 architecture) extracting informative features from any small, high-dimensional dataset. We use real-amplitude and strongly-entangling N-layer QML networks with and without data re-uploading layers as a multi-qubit QML network, and evaluate their expressive power quantified by using their local effective dimension; the lower the local effective dimension of a QML network, the better its performance on unseen data. Our numerical results show that the strongly-entangling N-layer QML network has a lower local effective dimension than the real-amplitude QML network and outperforms it on the hard-to-classify three-class labelling problem. In addition, quantum transfer learning helps tackle the two challenges mentioned above for benchmarking and validating QML networks on real-world, small, and high-dimensional datasets.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background Occupational accidents and work-related diseases cause over 2.3 million fatalities annually. This means that each year 54,000 workers die and 42 million work related accidents take place that cause at least three days' absence from work∙ Although few studies in Ethiopia showed that the prevalence of work related injury reaches up to 78.3%. But studies in iron and steel industries in Addis Ababa showed inconsistent finding. This study is believed to avoid uncertainty on previous findings and provide further information that may help policy makers, and trade unions in their efforts to improve occupational health and safety in iron and steel industries in Ethiopia. Objective - To assess the prevalence of work related injuries and associated risk factors among iron and steel industries workers in Addis Ababa, Ethiopia Methods- Institution based cross sectional study was conducted from March to April 2015 among 1110 randomly selected workers in Iron and steel industries. Data was collected using structured questionnaire by trained data collectors and analyzed using SPSS window version 20 where descriptive and logistics regression computed to see association between different factors and work related injuries. Result- The overall prevalence of occupational and work related injury was 35%. Among factors, Sex(male) [AOR 1.96, 95%CI: (1.05, 3.67)], Employment condition being temporary employee [AOR 2.65, 95%CI: (1.49, 4.71)], untrained on safety and health [AOR 1.92, 95%CI: (1.19, 3.11)], no shifting [AOR 1.50, 95%CI: (1.02, 2.21)], presence work place violence [AOR 1.88, 95%CI: (1.18, 2.98)], safe solid waste disposal system [AOR 2.01, 95%CI: (1.35, 3.02)] machine work [AOR 1.71, 95%CI: (1.13, 2.59)], unguarded machine [AOR 2.35, 95%CI: (1.46, 3.78)], cigarette smoking [AOR 4.78, 95%CI: (2.32, 2.59)], sleeping disorder [AOR 2.01, 95%CI: (1.16, 3.75)] and not using personal protective equipments [AOR 4.26, 95%CI: (2.78, 6.53)] were significantly associated with presence of injury. Conclusion and recommendation - the magnitude of work related injury in iron and steel industries was high and lack of safety and health training, work place violence, sleeping on work place, unavailability of safe waste disposal system, smoking cigarette, working on unguarded machine and not using PPE identified as risk factors. Therefore safety and health training and proper using of PPE should be given due attention in all iron and steel industries. Key words - work related injury, Iron and steel factors

Recently, for a small constant $\varepsilon >0 $, Bansal et al. gave a $(3/2-\varepsilon)$-approximation algorithm improving upon the natural barrier of $3/2$ which follows from independent randomized rounding. In simplified terms, their result is obtained by an enhancement of independent randomized rounding via strong negative correlation properties. In this work, we take a different approach and propose to use the same elegant rounding scheme for the weighted completion time objective as devised by Shmoys and Tardos for optimizing a linear function subject to makespan constraints. Our main result is a $1.21$-approximation algorithm for the natural special case where the weight of a job is proportional to its processing time (specifically, all jobs have the same Smith ratio), which expresses the notion that each unit of work has the same weight. In addition, as a direct consequence of the rounding, our algorithm also achieves a bi-criteria $2$-approximation for the makespan objective. Our technical contribution is a tight analysis of the expected cost of the solution compared to the one given by the Configuration-LP relaxation - we reduce this task to that of understanding certain worst-case instances which are simple to analyze.

description: A recent paper by two of us and co-workers, based on an extended Wigner's friend scenario, demonstrated that certain empirical correlations predicted by quantum theory (QT) violate inequalities derived from a set of metaphysical assumptions we called "Local Friendliness" (LF). These assumptions are strictly weaker than those used for deriving Bell inequalities. Crucial to the theorem was the premise that a quantum system with reversible evolution could be an observer (colloquially, a "friend"). However, that paper was noncommittal on what would constitute an observer for the purpose of an experiment. Here, we present a new LF no-go theorem which takes seriously the idea that a system's having *thoughts* is a sufficient condition for it to be an observer. Our new derivation of the LF inequalities uses four metaphysical assumptions, three of which are thought-related, including one that is explicitly called "Friendliness". These four assumptions, in conjunction, allow one to derive LF inequalities for experiments involving the type of system that "Friendliness" refers to. In addition to these four metaphysical assumptions, this new no-go theorem requires two assumptions about what is *technologically* feasible: Human-Level Artificial Intelligence, and Universal Quantum Computing which is fast and large scale. The latter is often motivated by the belief that QT is universal, but this is *not* an assumption of the theorem. The intent of the new theorem is to give a clear goal for future experimentalists, and a clear motivation for trying to achieve that goal. We review various approaches to QT in light of our theorem. The popular stance that "quantum theory needs no interpretation" does not question any of our assumptions and so is ruled out. Finally, we quantitatively discuss how difficult the experiment we envisage would be, and briefly discuss milestones on the paths towards it.

description: Background- Cobblestone production is highly labor intensive and physically demanding work that exposes workers for musculoskeletal disorders. Evidences on measuring exposure level are limited in this area. As a result studying the magnitude and factors incorporating the ergonomic hazard exposure level measurement is crucial. Objective- The main objective of the study is to assess the prevalence and associated factors of work related musculoskeletal disorders among cobble stone workers. Methods- Cross-sectional study was conducted from December 2016-June 2017 among cobble stone workers in Addis Ababa with a sample size of 537 using Nordic muscoloskletal disorder assessmet questionnaire and 56 paicipants using quick exposure cheek ergonomic hazard assessment tool. The data were collected by interviewing participants by trained six data collectors and three supervisors. The data were entered and cleaned using epi info version 7 and imported to statistical package for social science software version 20 for analysis. The data were analyzed using descriptive statistical method for magnitude and using bivariate and multivariable logistic regression models to identify factors associatiated with work related musculoskeletal disorder. Results- A total of 512 respondents included in this study, with 95% response rate.Over all 12 month prevalence 417(81.4%) of work related musculoskkletal disorder were obtained. From different body parts lower back is 65.5%, wrist 51.6%, shoulder 47.9% and neck 24.2% were found. Job stress (OR=1.75), working days (OR=3.38), awkward working posture (OR=3.29), lack of break time (OR=2.2) and ergonomic training (OR=2.9) found to be have statistically significant association with work related musculoskeltal disorder.The result obtained from quick exposure cheek reveals that exposure level of very high for back,high and very high for shoulder and wrist and moderate for neck. Conclusion and recommendation- Work related musculoskletal disorder among cobblestone workers are characterized with very high prevalence with high and very high ergonomic hazard exposure level for majority of body parts. Work load, twisting bending position, lack of break and lack of ergonomic training are factors for the development of work related musculoskletal disorders therefore ergonomic training mainly focusing on manual handling should be provided.

description: A number of searches at the LHC looking for low mass ($2m_μ - 62\ \mathrm{GeV}$) bosons in $\sqrt{s} = 8\ \mathrm{TeV}$ data have recently been published. We summarise the most pertinent ones, and look at how their limits affect a variety of supersymmetric and non-supersymmetric models which can give rise to such light bosons: the 2HDM (Types I and II), the NMSSM, and the nMSSM.

description: We show that the spin-lattice relaxation in n-type insulating GaAs is dramatically accelerated at low magnetic fields. The origin of this effect, that cannot be explained in terms of well-known diffusion-limited hyperfine relaxation, is found in the quadrupole relaxation, induced by fluctuating donor charges. Therefore, quadrupole relaxation, that governs low field nuclear spin relaxation in semiconductor quantum dots, but was so far supposed to be harmless to bulk nuclei spins in the absence of optical pumping can be studied and harnessed in much simpler model environment of n-GaAs bulk crystal.

description: Die Chat-Kommunikation ist linguistisch und interdisziplinär inzwischen gut untersucht. Die Chat-Forschung hat die Kommunikationsform Chat unter den unterschiedlichsten Perspektiven beschrieben und analysiert. Was noch fehlt, ist eine stilistische Untersuchung der Chat-Kommunikation. Diese liegt nun in Form einer exemplarischen, korpusbasierten Stilanalyse vor. Grundlage für die qualitative Bewertung der Ergebnisse sind die Arbeiten von Barbara Sandig zur Stilistik, insbesondere ihre Textstilistik von 2006. Bei der Beschreibung des Stils konzentriert sich die Dissertation auf die von Sandig eingeführte Beschreibungskategorie der stilistischen Handlungsmuster. Außerdem spielt die Kategorie der stilistischen Verfahren eine wichtige Rolle. Die Arbeit zeigt, dass Chatter vielfältige stilistische Möglichkeiten haben und, dass sie diese Möglichkeiten auch nutzen. Zahlreiche stilistische Verfahren werden am Beispiel des Korpus untersucht. Dabei werden die stilistischen Handlungsmuster ÖKONOMISIEREN, EMOTIONALISIEREN und SOLIDARISIEREN beschrieben. In den Betrachtungen spielen unter anderem Chat-Metaphern und Chat-Spiele eine zentrale Rolle. Untersucht werden aber auch andere in der Chat-Forschung immer wieder genannte chat-typische Phänomene wie Smileys, Action Messages, Asterisk-Ausdrücke bzw. Inflektive – hier als Verbstammphrasen bezeichnet – und Iterationen von Buchstaben und Satzzeichen. Alle untersuchten Phänomene werden in dem Korpus in sehr unterschiedlicher Häufigkeit und Ausprägung nachgewiesen. Genau hier wird es stilistisch interessant. Wichtig für die Beschreibung des Stils im Chat ist auch, die besondere Stellung des Chats zwischen Text und (Face-to-Face-)Gespräch zu berücksichtigen. Chat hat Elemente beider sprachlicher Realisierungsarten – der schriftlichen und der mündlichen – und bringt schon daher die Voraussetzungen mit, ein interessantes Forschungsobjekt der Stilistik zu sein, die im Sinne Sandigs das Chamäleon Stil zu fassen versucht.

description: Background: Flour is a complex organic dust containing a finished product of flour milling process. Flour dust generated during milling process is released into the air and later inhaled by a worker causes occupationally related lung diseases. Common respiratory health problems among flourmill dust exposed workers include a cough, wheezing, and shortness of breath and reduction of pulmonary function. Objectives: The aim of this study was to assess prevalence of chronic respiratory symptoms, pulmonary function and associated factors among flour factory workers in Hawassa city. Methods: Comparative cross-sectional study was conducted from January–April 2018 on a sample size of 406 from flour and Pepsi factories and spirometer test performed for 122 workers. Stratified and Systematic sampling methods used for selecting study subjects from each factory .Data was collected by using questionnaire and pulmonary function test equipment'. Data enter was done by using Epi data version 3.1 and cleaned and analyzed using SPSS version 24.Descriptive statistics and Odds ratios were used to describe the data and associated factors. Results: The mean age of flour factory and Pepsi factory participants were 32.1±9.99 and 31.28 ±7.87 respectively. This study reported that flour factory workers had significantly higher prevalence rate of chronic respiratory symptoms than Pepsi factory workers (56.6%; OR= 1.32, 95 % CI, 1.05-1.65). Chronic respiratory symptoms among flour factory workers were associated with working departments, (AOR = 5.3, 95% CI = 1.68-16.56), work experience (AOR= 5.1, 95 % CI = 2.05-12.48), working hours (AOR = 2.4, 95 % CI, 1.16-5.10) and educational level (AOR = 6.2, 95 %CI, 1.6-24.40). Significant reduction in the overall mean value, FEV1/FVC (p ≤ 0.003) in flour factory workers compared to Pepsi factory workers. Conclusion and recommendation: Based on the results of the study, conclude that exposure to flour mill dust increases the risk of developing occupationally related chronic respiratory symptoms and pulmonary function reduction. The results suggest that there is need to improve dust control measures in flour factory.
