The association between morbidity patterns and chemical hazards among industry workers in Iraqi Kurdistan Region: A cross-sectional study

--A chemical hazard is an occupational risk brought on by exposure to chemicals at work. Long-term or short-term health effects could result from chemical exposure at work. The study attempts to find the link between morbidity patterns and chemical hazards among industry workers in the Slemani Governorate, A worker-based crosssectional study was conducted among employees of large-scale factories. 300 workers from ten different industries took a part in the current study. The right number of employees per factory was determined using a proportionate method, and then the employees were selected on purpose. Thirty workers were used for a pilot study, and they were excluded from the original sample size. The workers were interviewed using a developed questionnaire The data was analyzed using descriptive and inferential statistics methods (Kruskalwallis H test). Among 300 industry workers 44.7% were found in good health, 32.3% of workers were overweight, followed by 8% of them who were obese and 3.7% of them who had musculoskeletal issues. Even though the study observed out of 300 participating workers in 10 industries, 116 of them were exposed to chemical hazards which accounts slightly more than half of represents 50.9%. Also, a significant difference was noted between morbidity patterns and chemical hazards among the participating workers. It is necessary to awareness raising among industries workers regarding chemical substances hazards and their health problems in addition at the national and workplace levels, a preventative safety and health culture should be formed, with different stakeholders involved at all levels
Comparison of incidence of post spinal hypotension between pre-loading and co-loading of fluid in parturient undergoing elective caesarean section with perfusion index greater than 3.5

Background: Spinal anesthesia is most preferred method of anesthesia in both emergency and elective caesarean deliveries. It helps reduce complications related to general anesthesia but it has spectrum of complications, most common being hypotension due to sympathetic blockade. Perfusion index greater than 3.5 is associated with higher incidence of post spinal hypotension. Preloading and coloading of crystalloid have been studied and showed different results, this study compares preloading and coloading in patients with PI>3.5. Materials and Method: Sixty-four (32 each group) parturient with PI>3.5, ASA II and posted for elective caesarean delivery were enrolled. Preload group (group P) and Coload group (group C) both received 15ml/kg of fluid through 16 G IV cannula. Preload group received 20 minutes before and group C received right after spinal anesthesia. Vitals were recorded at baseline, every two minutes for first 10 minutes then every five minutes there after till end of operation. Bupivacaine heavy 0.5% 2ml was given at L3-4 in sitting position. Severe hypotension was treated with bolus Mephentermine. Results: Demographic data were comparable between groups. Systolic, diastolic and mean arterial pressure, heart rate, saturation showed no statistical significance. Incidence of hypotension was 68.75% in group P. 62.5% in group C (p=0.599). 59.37% received vasopressor in group P and 37.5% received vasopressor in group C (P=0.08). There was no statistically significant difference between the two groups. Conclusion: Both Preloading and coloading of fluid decreased incidence of hypotension in parturient with PI value greater than 3.5. The reduction in incidence of hypotension was more in group C. Need of vasopressor was more in group P. The results being statistically not significant we cannot recommend one method over the other.
Associations between everyday activities and arterial spin labeling‐derived cerebral blood flow: A longitudinal study in community‐dwelling elderly volunteers

Cerebral blood flow (CBF) is critical for brain metabolism and function. Age‐related changes in CBF are associated with increased risk of neurocognitive disorders and vascular events such as stroke. Identifying correlates and positive modifiers of age‐related changes in CBF before the emergence of incipient clinical decline may inform public health advice and clinical practice. Former research has been inconclusive regarding the association between regular physical activity and CBF, and there is a lack of studies on the association between level of everyday activities and CBF, in older adults. To investigate these relationships, 118 healthy community‐dwelling adults (65–89 years) underwent pseudo‐continuous arterial spin labeling (ASL) MRI, neurocognitive, physical, and activity assessments at baseline. Eighty‐six participants completed a follow‐up ASL MRI, on average 506 (SD = 113) days after the baseline scan. Cross‐sectional analysis revealed credible evidence for positive associations between time spent on low intensity physical activity and CBF in multiple cortical and subcortical regions, time spent on moderate to vigorous intensity physical activity and accumbens CBF, participation in social activity and CBF in multiple cortical regions, and between reading and thalamic CBF, indicating higher regional CBF in more active adults. Longitudinal analysis revealed anecdotal evidence for an interaction between time and baseline level of gardening on occipital and parietal CBF, and baseline reading on pallidum CBF, indicating more change in CBF in adults with lower level of activity. The findings support that malleable lifestyle factors contribute to healthy brain aging, with relevance for public health guidelines.
Omicron Subvariants: Clinical, Laboratory, and Cell Culture Characterization

Abstract Background The variant of concern Omicron has become the sole circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant for the past several months. Omicron subvariants BA.1, BA.2, BA.3, BA.4, and BA.5 evolved over the time, with BA.1 causing the largest wave of infections globally in December 2021–January 2022. This study compared the clinical outcomes in patients infected with different Omicron subvariants and the relative viral loads and recovery of infectious virus from upper respiratory specimens. Methods SARS-CoV-2–positive remnant clinical specimens, diagnosed at the Johns Hopkins Microbiology Laboratory between December 2021 and July 2022, were used for whole-genome sequencing. The clinical outcomes of infections with Omicron subvariants were compared with infections with BA.1. Cycle threshold (Ct) values and the recovery of infectious virus on the VeroTMPRSS2 cell line from clinical specimens were compared. Results BA.1 was associated with the largest increase in SARS-CoV-2 positivity rate and coronavirus disease 2019 (COVID-19)–related hospitalizations at the Johns Hopkins system. After a peak in January, cases decreased in the spring, but the emergence of BA.2. 12.1 followed by BA.5 in May 2022 led to an increase in case positivity and admissions. BA.1 infections had a lower mean Ct value when compared with other Omicron subvariants. BA.5 samples had a greater likelihood of having infectious virus at Ct values <20. Conclusions Omicron subvariants continue to be associated with a relatively high rate of polymerase chain reaction (PCR) positivity and hospital admissions. The BA.5 infections are more while BA.2 infections are less likely to have infectious virus, suggesting potential differences in infectibility during the Omicron waves.
Rotationally symmetric harmonic maps from a ball into a sphere and the regularity problem for weak solutions of elliptic systems.

which despite its simplicity involves some of the main difficulties of nonlinear elliptic Systems. The analysis of the existence, uniqueness, regularity and stability of its rotationally Symmetrie Solutions is not only instructive but also contributes to the general theory. For instance, it can be shown that the only known solution with singularities is unstable in dimension «, 3 ̂ «^6, but stable for n^l.
Defect passivation with potassium trifluoroborate for efficient spray-coated perovskite solar cells in air

Defects as non-radiative recombination centers hinder the further efficiency improvements of perovskite solar cells (PSCs). Additive engineering has been demonstrated to be an effective method for defect passivation in perovskite films. Here, we employed (4-methoxyphenyl) potassium trifluoroborate (C7H7BF3KO) with and K+ functional groups to passivate spray-coated (FAPbI3) x (MAPbBr3)1–x perovskite and eliminate hysteresis. It is shown that the F of can form hydrogen bonds with the H atom in the amino group of MA+/FA+ ions of perovskite, thus reducing the generation of MA+/FA+ vacancies and improving device efficiency. Meanwhile, K+ and reduced MA+/FA+ vacancies can inhibit ion migration, thereby eliminating hysteresis. With the aid of C7H7BF3KO, we obtained hysteresis-free PSCs with the maximum efficiency of 19.5% by spray-coating in air. Our work demonstrates that additive engineering is promising to improve the performance of spray-coated PSCs.
Deformations of $\Xi(s)=\Xi(1-s)$ and the heat equation

This paper studies deformations of the well-known $\Xi(s)=\Xi(1-s)$ equation for the Riemann $\Xi$ function satisfied by $\Xi_\rho(s):=\int_{0}^\infty\frac{{\d}t}{t}{t^{\frac{s}{2}}}\Psi(t)e^{-\rho\ln^2(t)}$ where ${\Psi(t)=\sum_{n\in\mathbb{N}^+}e^{-\pi{n}^2t}}$.
LIMITS OF ELECTRODYNAMICS: PARAPHOTONS?

1. The possible existence of new long-range interactions has attracted increasing attention during recent times. To a certain degree, this is related to various symmetry and supersymmetry schemes in elementary particle theory, for which the predictions are, unfortunately, at present far from unique (see, e.g., the discussion of a superlight vector boson which simulates antigravity,' of a light axial-vector b ~ , o n , ~ superlight scalar and pseudoscalar b o ~ o n s , ~ macrosc~. ;.: confinement4). To a certain degree the interest in new longrange interactions is due to natural scientific curiosity, the desire to find out5 to what level the standard conceptions about long-range forces (gravitational and electromagnetic) are verified experimentally. Searches for very light and very weakly interacting new particles became promising after it was understood that the mass scale in elementary particle physics is defined probably by the Planck mass m,, z 1019 GeV (see, e.g., the review6). At this scale the masses of the electron and of the proton are very small, and the next ranks of the mass hierarchy may indeed correspond to particles which are by 20 to 40 orders of magnitude lighter than the electron. From a phenomenological point of view there exist rigid bounds on the coupling constants of new superlight bosons (i.e., long-range fields) to stable matter. These bounds are derived essentially from the very precise Eotvos experiments and their latter-day analogs (Ref. 7). Thus, for the hypothetical baryonic and leptonic photons the analogs corresponding to the electromagnetic fine structure constant a = 1/137 are respectively 5 and 5 (see, Ref. 8). The bounds on the interactions of hypothetical long-range scalar fields with electrons and nucleons are at the same level. From this point of view an exceptional position would be assumed by a superlight hypothetical vector particle which would interact, just as an ordinary photon, only with the electromagnetic current, for owing to the electric neutrality of ordinary matter experiments of the Eotvos type do not yield any constraints on the coupling constants of such particles. 2. We shall consider a modified electrodynamics, containing two photons A , and A, (we shall call these paraphotons) with masses m, < m, and coupling constants el and e,, described by the Lagrangian The data on the magnetic field of Jupiter indicate9 (see, also the reviews1') that l/ml 2 lo6 km (we use units with fi = c = l), whereas data on galactic magnetic fields indicate" that l/m, k 1017 km. It is easy to see that these data also indicate that el cannot be substantially smaller than e. Let us find out what kind of constraints exist on e, at various values of m,. 3. For small distances r( l/m, the Coulomb interaction between charges is due to exchange of the fields A, and A,, so that
Morphological scale-space with application to three-dimensional object recognition

This thesis develops and demonstrates an original approach to scale-space theory. A new scale-space theory based on a unified multiscale morphological dilation-erosion smoothing operator is presented. The essential scale-space causality property for local extrema of a signal under this operation is proved. This result holds for signals on $\IR\sp2$ and higher dimensions and for negative as well as positive scales. When applied to grayscale images we show that structuring functions from the "elliptic poweroids" lead to favourable dimensionality and semi-group properties. Paraboloids, in particular, allow efficient computation of the scale-space, and such an algorithm is presented. The generalised frequency response of this signal smoother, which is similar to that of a Butterworth filter (with an amplitude dependent corner frequency), is obtained. The filter is statistically characterised by obtaining second-order statistical properties of the output signal with independent and identically distributed uniform noise input. Similar scale-space results are obtained for the multiscale morphological closing-opening operator, and we show that the resulting scale-space fingerprints are identical to those of the dilation-erosion. To demonstrate the utility of the new theory, we present an approach for the recognition of multiple 3-D objects in range data via the local matching of surfaces. In this approach the reduced morphological scale-space fingerprint is used as the primitive for matching. The resulting recognition process is invariant to translation, rotation, limited scaling, and partial occlusion. The results of the proposed object recognition method showing the recognition of a scene containing nine faces at various positions, angles and scales is presented. In a second demonstration we show the recognition of eight mountains in a digital elevation map.
Cylindrically Symmetric Cosmological Models in Bimetric Theory

Spherically symmetric Kantowski-Sachs space-time is studied in Rosen’s (1973) bimetric theory of gravitation, considering the source of gravitation as perfect fluid and scalar meson field. It is shown that a macro cosmological model – represented by perfect fluid distribution – does not exist, and only a vacuum model can be constructed, whereas in case of a micro cosmological model represented by a scalar meson field exists, and the model is obtained as in the case of Mohanty & Sahoo (2002).

Torsion classes, wide subcategories and localisations

For a finite‐dimensional algebra A , we establish correspondences between torsion classes and wide subcategories in mod(A) . In case A is representation finite, we obtain an explicit bijection between these two classes of subcategories. Moreover, we translate our results to the language of ring epimorphisms and universal localisations. It turns out that universal localisations over representation finite algebras are classified by torsion classes and support τ ‐tilting modules.
Measurement of J/psi and psi(2S) prompt double-differential cross sections in pp collisions at sqrt(s) = 7 TeV

The double-differential cross sections of promptly produced J/ ψ and ψ ( 2S ) mesons are measured in pp collisions at √ s = 7 TeV, as a function of transverse momentum p T and absolute rapidity | y | . The analysis uses J/ ψ and ψ ( 2S ) dimuon samples collected by the CMS experiment, corresponding to integrated luminosities of 4.55 and 4.90 fb − 1 , respectively. The results are based on a two-dimensional analysis of the dimuon invariant mass and decay length, and extend to p T = 120 and 100 GeV for the J/ ψ and ψ ( 2S ) , respectively, when integrated over the interval | y | < 1.2. The ratio of the ψ ( 2S ) to J/ ψ cross sections is also reported for | y | < 1.2, over the range 10 < p T < 100 GeV. These are the highest p T values for which the cross sections and ratio have been measured.
Heating Rate Proﬁles in Galaxy Clusters

The results of hydrodynamic simulations of the Virgo and Perseus clusters suggest that thermal conduction is not responsible for the observed temperature and density proﬁles. As a result it seems that thermal conduction occurs at a much lower level than the Spitzer value. Comparing cavity enthalpies to the radiative losses within the cooling radius for seven clusters suggests that some clusters are probably heated by sporadic, but extremely powerful, AGN outﬂows interspersed between more frequent but lower power outﬂows.
Local well-posedness and break-down criterion
 of the incompressible Euler equations with free
 boundary

In this paper, we prove the local well-posedness of the free boundary problem for the incompressible Euler equations in low regularity Sobolev spaces, in which the velocity is a Lipschtiz function and the free surface belongs to $C^{\f32+\varepsilon}$. Moreover, we also present a Beale-Kato-Majda type break-down criterion of smooth solution in terms of the mean curvature of the free surface, the gradient of the velocity and Taylor sign condition.
On the infinitesimal theory of Chow groups

The Chow groups of codimension-p algebraic cycles modulo rational equivalence on a smooth algebraic variety X have steadfastly resisted the efforts of algebraic geometers to fathom their structure. This book explores a "linearization" approach to this problem, focusing on the infinitesimal structure of the Chow groups near their identity elements. This method was adumbrated in recent work of Mark Green and Phillip Griffiths. Similar topics have been explored by Bloch, Stienstra, Hesselholt, Van der Kallen, and others. A famous formula of Bloch expresses the Chow groups as Zariski sheaf cohomology groups of algebraic K-theory sheaves on X. "Linearization" of the Chow groups is thereby related to "linearization" of algebraic K-theory, which may be described in terms of negative cyclic homology. The "proper formal construction" arising from this approach is a "machine" involving the coniveau spectral sequences arising from four different generalized cohomology theories on X, with the last two sequences connected by the algebraic Chern character. Due to the critical role of the coniveau filtration, I refer to this construction as the coniveau machine. The main theorem in this book establishes the existence of the coniveau machine for algebraic K-theory on a smooth algebraic variety. An immediate corollary is a new formula expressing generalized tangent groups of Chow groups in terms of negative cyclic homology.
TARGETing secondary school students’ motivation towards physical education: The role of student-perceived mastery climate teaching strategies

The aim of the present study was to explore the impact of TARGET-based teaching strategies on students’ motivation in a Dutch secondary school PE context. We examined to what extent mastery climate teaching strategies perceived by students (independently or interactively) explain variability in students’ motivation towards PE. In total 3,150 students (48.2% girls; 51.8% boys) with a mean age of 13.91 years (SD = 1.40) completed the Behavioural Regulations in Physical Education Questionnaire (BRPEQ), measuring students’ autonomous motivation, controlled motivation and amotivation, and the Mastery Teaching Perception Questionnaire (MTP-Q), measuring student-perceived application of mastery TARGET teaching strategies. Hierarchical regression analyses indicated that after controlling for gender, age, and educational type, the predictive effects of the perceived mastery climate teaching strategies differed by motivational outcome. Overall, students who reported higher levels of perceived application of mastery TARGET teaching strategies showed more autonomous motivation and less amotivation. Specifically, the teaching strategies within the task structure were the strongest predictors for students’ autonomous motivation and amotivation. No meaningful statistically significant two-way interaction effects between any of the TARGET variables were found, supporting the proposition of an additive relationship between the TARGET teaching strategies.
Looking inside the Blackbox: Cuenca’s water metabolism

The socio-ecological metabolism of the water connects concepts that emerge out of the complexity of ecosystems, linking endosomatic processes that are indispensable for society while forming different hierarchic levels and relations among as well as aligning to their particularities. The consumptive uses of Cuenca city in their different categories and social metabolism both at rural and urban levels were assessed, inquiring about diverse typologies of the city’s water. Water Metabolic Rates (WMR) were calculated for each one of the consumptives’ uses gauged in liters per hour of human activity. Our results indicate that farming and industrial uses of water were highly inefficient. Linked to farms, both consumption of water and metabolic rates were higher in the rural areas. While paid work showed higher metabolic rates than households. Rural households evidenced a greater use of water and higher metabolic rates than urban households as water use combines human consumption and family farming. This research determined the water metabolism of the socio-ecological system in the canton of Cuenca, Ecuador through different dimensions of water metabolism. Formulating a system of flows and uses of water that were metabolized by different hierarchy levels of diverse consumptive uses within the aforementioned canton, as a tool to implement policies that guarantee water access and ecological metabolism, linking social dynamics within ecosystems.
Robust natural depth for anticorrelated random dot stereogram for edge stimuli, but minimal reversed depth for embedded circular stimuli, irrespective of eccentricity

The small differences between the images formed in our left and right eyes are an important cue to the three-dimensional structure of scenes. These disparities are encoded by binocular neurons in the visual cortex. At the earliest stage of processing, these respond to binocular correlation between images. We assessed the perception of depth in anticorrelated stimuli, in which the contrast polarity in one eye is reversed, as a function of their location in the retinal image, and their depth configuration (a horizontal edge or a circle surrounded by an annulus) We found that, regardless of stimulus eccentricity, participants perceived depth in the natural direction for edge stimuli, and weakened, reversed depth for circular stimuli.
