Publisher: name: tourismos
Year: 2011

description: The design of new tourism products necessarily enters into the realm of uncertainty. Such uncertainty concerns the product developed and its later use as much as the way the design project is conducted. It can be linked to events either within or outside the firm. It will be considered to be acceptable by the design team concerned as long as it remains within a field of tolerance (domain of performance, “margin for random effects”, etc.), with the risk relating to how to egress from that domain. The first section addresses the issue of uncertainty in design and concerns the developed product and its later use just as the way the design project is pursued. The second section focuses on decision-making and how the various risks that can affect the firm and its environment are taken into account.

description: We propose and evaluate experimentally an approach to quantum process tomography that completely removes the scaling problem plaguing the standard approach. The key to this simplification is the incorporation of prior knowledge of the class of physical interactions involved in generating the dynamics, which reduces the problem to one of parameter estimation. This allows part of the problem to be tackled using efficient convex methods, which, when coupled with a constraint on some parameters allows globally optimal estimates for the Kraus operators to be determined from experimental data. Parameterising the maps provides further advantages: it allows the incorporation of mixed states of the environment as well as some initial correlation between the system and environment, both of which are common physical situations following excitation of the system away from thermal equilibrium. Although the approach is not universal, in cases where it is valid it returns a complete set of positive maps for the dynamical evolution of a quantum system at all times.

description: Real-time robotic grasping, supporting a subsequent precise object-in-hand operation task, is a priority target towards highly advanced autonomous systems. However, such an algorithm which can perform sufficiently-accurate grasping with time efficiency is yet to be found. This paper proposes a novel method with a 2-stage approach that combines a fast 2D object recognition using a deep neural network and a subsequent accurate and fast 6D pose estimation based on Point Pair Feature framework to form a real-time 3D object recognition and grasping solution capable of multi-object class scenes. The proposed solution has a potential to perform robustly on real-time applications, requiring both efficiency and accuracy. In order to validate our method, we conducted extensive and thorough experiments involving laborious preparation of our own dataset. The experiment results show that the proposed method scores 97.37% accuracy in 5cm5deg metric and 99.37% in Average Distance metric. Experiment results have shown an overall 62% relative improvement (5cm5deg metric) and 52.48% (Average Distance metric) by using the proposed method. Moreover, the pose estimation execution also showed an average improvement of 47.6% in running time. Finally, to illustrate the overall efficiency of the system in real-time operations, a pick-and-place robotic experiment is conducted and has shown a convincing success rate with 90% of accuracy.

description: In Drosophila the steroid hormone ecdysone regulates a wide range of developmental and physiological responses, including reproduction, embryogenesis, postembryonic development and metamorphosis. Drosophila provides an excellent system to address some fundamental questions linked to hormone actions. In fact, the apparent relative simplicity of its hormone signaling pathways taken together with well-established genetic and genomic tools developed to this purpose, defines this insect as an ideal model system for studying the molecular mechanisms through which steroid hormones act. 
During my PhD research program I’ve analyzed the role of ecdysone signaling to gain insight into the molecular mechanisms through which the hormone fulfills its pleiotropic functions in two different developmental stages: the oogenesis and the imaginal wing disc morphogenesis. To this purpose, I performed a reverse genetic analysis to silence the function of two different genes involved in ecdysone signaling pathway, EcR and ecd.
title: Autonomous Trajectory Planning for Satellite RPO and Safety of Flight Using Convex Optimization
Creators: name: Ortolano, Nicholas G.
Publisher: name: Utah State University
Year: 2018

description: Optimal trajectory planning methods that implement convex optimization techniques are applied to the area of satellite rendezvous and proximity operations. This involves the development of linearized relative orbital motion dynamics and constraints for two satellites, where one maintains a near-circular reference orbit. The result is formulated as a convex optimization problem, where the objective is to minimize the amount of fuel required to transfer from a given initial condition to the desired final conditions. A traditional rendezvous and proximity operations scenario is analyzed, which includes examples of initial approach, inspection, final approach, and docking trajectories. This scenario may include trajectory constraints such as maximum allowable control acceleration levels, approach corridors, and spherical keep-out zones. A second scenario that ensures passive safety, in the event of control failures on the maneuvering satellite. The convex optimization problem is ultimately formulated as a second-order cone program. Algorithm CPU and memory requirements are analyzed. Several examples of resulting optimal trajectories are presented for both scenarios, and these trajectories are implemented in a nonlinear simulation.

title: An Evaluation of the Social Validity of the Center for Advanced Professional Studies (CAPS) Program
Creators: name: Watt, Jason L.
Publisher: name: Utah State University
Year: 2018

description: The Center for Advanced Professional Studies (CAPS) programs are emerging high school programs emphasizing immersive, real-life professional experiences for students. CAPS programs endeavor to facilitate student-centered partnerships between business and public education to produce personalized learning experiences for students centered around the completion of real-world industry projects.
To ensure successful educational programs, leaders must consider more than simple outcome data or statistical descriptions of the program’s reliability and validity. Successful leaders of schools must also determine the program’s value from the perspective of the stakeholders it purports to serve—that is, by its social validity. Understanding what consumers of education do and do not find valuable is crucial when developing, implementing, and evaluating educational programs. Unfortunately, this type of evaluation is seldom utilized and has resulted in a nearly inaudible stakeholder voice in public education and its programs.
This study evaluated the dimensions of social validity associated with the CAPS program from the perspective of both students and industry partners as consumers. Social validity data was collected via a modified Behavior Intervention Rating Scale (BIRS). Participants were asked to rate CAPS programs by agreeing or disagreeing with each of 20 BIRS statements. Respondents included 459 students and 107 industry partners from twelve CAPS programs in six states.
Data from both students and industry partners were analyzed to determine the social validity of CAPS programs. Both students and industry partners rated CAPS programs impressively high on both its acceptability and its effectiveness. CAPS programs are well-positioned to continue to provide positive educational outcomes and experiences to both students and industry partners.

description: The metabolic activity of microbes has played an essential role in the evolution and persistence of life on Earth. Microbial metabolism plays a primary role in the flow of carbon, nitrogen and other elements through the biosphere on a global scale. Microbes perform these metabolic activities in the context of complex communities comprised of many species that interact in dynamic and spatially-structured environments. Molecular genetics has revealed many of the metabolic pathways microbes utilize to generate energy and biomass. However, most of this knowledge is derived from model organisms, so we have a limited view of role of the massive genomic diversity in the wild on metabolic phenotypes. Further, we are only beginning to glimpse the principles governing how the metabolism of a community emerges from the collective action of its constituent members. As a result, one of the biggest challenges in the field is to understand how the metabolic activity of a community emerges from the genomic structure of the constituents. Here we propose an approach to this problem that rests on the quantitative analysis of metabolic activity in ensembles of microbial communities. We propose quantifying metabolic fluxes in diverse communities, either in the laboratory or the wild. We suggest that using sequencing data to quantify the genomic, taxonomic or transcriptional variation across an ensemble of communities can reveal low-dimensional descriptions of community structure that can explain or predict their emergent metabolic activity. We survey the types of communities for which this approach might be best suited and then review the analytical techniques available for quantifying metabolite dynamics in communities. Finally, we discuss what types of data analysis approaches might be lucrative for learning the structure-function mapping in communities from these data.

title: Exploring the Moderating Effect of Cognitive Autonomy on the Relationship Between Cognitive Distortions and Youth’s Externalizing Behaviors
Creators: name: Fischback, Liam J.
Publisher: name: Utah State University
Year: 2018

description: Scholars have connected cognitive distortions to adolescents’ externalizing behaviors. Other scholars have offered that higher levels of cognitive autonomy, which develops during adolescence, may be a protective factor for problem behaviors in adolescence. To date, no studies have explored how these two cognitive processes function and potentially interact to predict adolescent problem behaviors. This study’s purpose was to see if cognitive autonomy affected the relationship between cognitive distortions and externalizing behaviors in a clinical population of adolescents. Past research has suggested that cognitive distortions are greater and more prevalent in clinical populations. Because of this, the processes of cognitive autonomy could be affected by cognitive distortions (that can form prior to adolescence), and worsen the relationship between cognitive distortions and externalizing behaviors. This study analyzed 146 adolescents, from a residential treatment facility. Hierarchical multiple regression analyses were used to examine if links between cognitive distortions, cognitive autonomy, and externalizing behaviors existed, and to determine if elements of cognitive autonomy affected the relationship between cognitive distortions and externalizing behaviors. As expected, analyses showed that cognitive distortions and externalizing behaviors were related. Additionally, results indicated that aspects of cognitive autonomy were protective of externalizing behaviors. Results did not reveal that cognitive autonomy affected the relationship between cognitive distortions and externalizing behaviors. Discussion highlights potential reasons and alternative explanations for the results that were inconsistent with expectations. Limitations and future directions also are discussed.

description: Community-based Tourism is gaining prestige all over the world as an alternative to mass tourism. This new type of tourism favours a contact with the local community and the experimentation of different sensations. In this paper we show a study carried out in El Salvador about the opinions that residents have in order to develop a tourist destination based on the hospitality of hosts, on the remarkable ecologic resources of the area, and in the important of the role of the residents. The methodology is based on an empirical study realized in a rural area from September to November 2008. Most outstanding result is the local community perception that tourist development can create jobs and generate wealth, although it is necessary previous technical training from private and public institutions to fulfil these objectives.

Creators: name: Converse, Noelle E.
Publisher: name: Utah State University
Year: 2018

description: This study evaluated the effect of an explicit comprehension read-aloud routine of science content on first grade students’ listening comprehension.The read-aloud routine taught the structures common in the informational text (compare, contrast, and compare-contrast) and found in first grade science big books with the goal of improving understanding of the science content. Students who received the intervention showed improvements in their ability to understand the compare-contrast text structures compared to students who were taught the same content without the routine or students who were taught typical science read-aloud content without the routine. Observations revealed that teachers who were most consistent in implementing high quality comprehension strategies during the read aloud had students who made the best gains in listening comprehension of the content, regardless of whether the teachers used explicit text the compare-contrast text structure routine.The results demonstrated that even though the instruction of the compare-contrast text structures was not necessary to produce listening comprehension of science content, the compare-contrast instruction added value to the high quality comprehension instruction for students assigned to the intervention group. The results of the study are discussed in terms of the available research on instruction of informational text structures in the early grades. Recommendations for future research are provided.

description: Abstract

We performed Whole-genome sequencing (WGS) of six S. aureus strains isolated from Peshawar, Pakistan, was conducted in this present study to identify the possible pangenome of S. aureus. These strains were then compared with the 200 fully sequenced genomes and 27 draft genomes of S. aureus from Pakistan available in the PATRIC database. Bioinformatics studies involving sequence assembly, quality check, Multi-Locus Sequence Typing (MLST), and Cluster of Orthologous Genes (COGs) were performed to examine the genetic variations and the evolutionary patterns of these strains. The de novo assembly of the S. aureus genomes indicated the genome size to lie between 1. 6 to 2. 9 Mb with average GC percentage. MLST analysis identified diverse sequence types among SA1, SA2, SA3, SA4, SA5, SA6 isolates belong to ST 45, 30, 772, 1413, 30, 30 and carries no SCCmec, (mecA gene, SCCmec type V, VII, mecA), mecA, (SCCmec type IV, mecA, Iva), (SCCmec type IV, mecA, Iva). Using the pangenome analysis of the 200 S. aureus genomes, it found a total of 9, 118 genes while sharing 1, 620 core genes, 307 soft core genes, 1, 161 shell genes, and the remaining 6, 030 of cloud genes. Thus, this analysis reveals the fact that the pangenome of S. aureus is open, suggesting its ability to obtain new genes and adapt to the environment. The COG analysis showed the functional classifications of the genes underlying metabolic processes. These outcomes are crucial for clinicians and therapeutic strategies for treating bacterial S. aureus infections.

description: This study aims at evaluating the ethical approaches effective for managers working at hotel business when making decisions. Ethics, in the working place, refers to the rules of the workplace that an employee has to comply with, along with the rules of society. In the study, the concept of ethics has been examined within theories of ethics, followed by a conceptual framework of making ethical decisions. The scope of the study consists of interviews conducted with 60 managers working in a chain hotel. The interview consists of 5 different scenarios relating to ethical dilemmas. The scenarios are composed of three different ethics approaches (moral justice approach, subjective approach and contract -based theoretical approach). In the analysis of the data, the Manova Analysis was carried out. The results suggest that managers prefer the contract -based theoretical approach more frequently in decision making. It was also found that managers differ in their choice of ethical approaches in terms of the scenarios. This difference is caused by subjective approaches which are used when dealing with problems related to socio-cultural and institutional reputation and ecology.

description: Abstract

The bacterial isolate, identified as Pediococcus acidilactici (NMCC-G, MK072824, 97.65% similarity) with the sequences of different lactic acid bacteria species in the NCBI genes database was used for the production of novel probiotics. A biological trial was conducted by using one-day-old Ross-308 broiler birds to determine the supplemental effects of novel indigenous probiotics. The broiler chicks were allocated at random to one of the five dietary treatment groups in a way that each treatment group was fed to 5 replicates with 15 birds per replicate. Dietary treatments include probiotic-free basal diet (Control; C), indigenous probiotic (2.01 x 109 CFU/g) with three different inclusion levels; 1 gm/10 kg of diet (IProb-1), 1.5 gm/10 kg of diet (IProb-2) and 2.0 gm/10 kg of diet (IProb-3). The broiler diets were formulated according to nutrient specifications for Ross-308. The results indicated that broilers fed diets supplemented with IProb-3 had lower feed intake, higher (P<0.05) body weight gain, and better FCR in comparison to broilers fed control (no probiotics). Carcass yield and breast meat yield increased with increasing levels of IProb. The highest values were noted in IProb-3 (@ 2 gm/10 kg of diet). The total tract apparent digestibility coefficient for crude protein and dry matter was higher in probiotic-supplemented groups compared to the control.  In conclusion, the locally isolated Pediococcus acidilactici NMCC-G strain @ 2.0 gm/10 kg (having 2.01 x109 CFU/g) resulted in better growth and feed efficiency in broiler birds as compared to that of non-supplemented birds.
GENDERED LEISURE: ARE WOMEN MORE CONSTRAINED IN TRAVEL FOR LEISURE?
Creators: name: Khan, Sonia
Publisher: name: tourismos
Year: 2011

description: The equality of genders has always remained a contentious issue. Every sphere of life is characterized by differential status ascribed to men and women. It has been argued that women have long been the disadvantaged gender in leisure. Taking specifically the case of travel for leisure, this study is an attempt to explore if socio-demographic factors like family responsibilities, dominance of spouse and/or family, employment status, and one’s gender are dominant in governing travel decisions and to what extent theses are perceived as constraints by male and female tourists. This comparative study of genders arrives at the finding that gender is the detrimental factor for women in participation in travel for leisure. For men, time limitation associated with employment is the major constraint restricting their freedom to travel. Women remain relatively more constrained by familial responsibilities but in today’s world women cannot be identified as the disadvantaged gender in leisure.

description: We study the variation of average powers and spectral indices of electric field fluctuations with respect to the angle between average flow direction and the mean magnetic field in solar wind turbulence. Cluster spacecraft data from the years 2002 and 2007 are used for the present analysis. We perform a scale dependent study with respect to the local mean magnetic field using wavelet analysis technique. Prominent anisotropies are found for both the spectral index and power levels of the electric power spectra. Similar to the magnetic field fluctuations, the parallel (or antiparallel) electric fluctuation spectrum is found to be steeper than the perpendicular spectrum. However the parallel (or antiparallel) electric power is found to be greater than the perpendicular one. Below 0.1 Hz, the slope of the parallel electric power spectra deviates substantially from that of the total magnetic power spectra, supporting the existence of Alfvénic turbulence.

Year: 1982

description: The relationship between clone and cone color in western white pine, Pinus monticola Douglas, to attack by the mountain pine cone beetle, Conophthorus monticolae Hopkins, was studied in the Sandpoint Seed Orchard, Idaho. A positive relationship was shown to exist during a 5 year field evaluation. Cone beetles were found to prefer dark colored cones and to attack certain clones at a higher rate than others.
Laboratory dissections did not indicate that cone color affected oviposition, brood development or brood mortality.
Olfactometer experiments demonstrated that olfactory stimuli are involved in the cone beetle attack sequence. Visual cues relating to cone color may be involved in the initial long range host orientation of attacking beetles.

A histochemical and ultrastructural study of the ovary and vitellogenesis in the dogfish Squalus acanthias
Creators: name: Reid, James Allen
Publisher: name: University of British Columbia
Year: 2010

description: Protein yolk formation is being studied in an ever increasing number of organisms and in each the method of formation (i.e. intra-oocytic vs extraoocytic) and the organelles involved (Golgi, mitochondria etc.) differ even though the final product is markedly similar. Previous emphasis on elasmobranchs in this laboratory and the availability of the specimen favoured the selection of Squalus acanthias as the experimental animal as veil as the lack of any pertinent studies on its ovary or vitellogenic processes. While examining the problem of yolk formation with both histochemical and ultrastructural techniques, several other critical areas of investigation were pursued. As a result, the composition of the follicular envelope and the formation of its associated membranes, the surface epithelium, the tunica albuginea, the ovarian cortex and the lacunae border cells were also examined. An examination of representative oocytes from 0.1 to 4.0 mm in diameter revealed many important facts. First, these oocytes are in a prolonged diplotene with up to 100 nucleoli present, each rich in rRNA represented ultrastructurally by their granular nature. Secondly, a complex Balbiani body rich in protein and RNA and composed of mitochondria and SER is present. Here, this mitochondrial mass is the center for mitochondrial multiplication. Thirdly, lipid yolk is formed before proteinaceous yolk and it arises de novo in the ooplasm from extra-oocytically derived materials. Finally, proteid yolk arises from two sources. Initially, multigranular (MGB) and multivesicular (MVB) bodies form from Golgi, SER, micropinocytotic vesicles and vesicles derived from the nuclear membrane which fuse together forming granular-vesicular bodies (GVB). In oocytes larger than 0.k mm, distended Golgi lamellae, SER cisternae and loops of SER vesicles form limiting membranes and take up MGBs, MVBs and small GVBs. The contents of these large GVBs then dissolve, reaggregate and crystallize forming a mature yolk platelet. Of the other areas examined, the basal lamina, the vitelline membrane and the follicle cells were the most relevant to yolk formation. The follicle cells were implicated in the formation of both the lamina and the vitelline membrane. The former are predominantly acid and sulphated mucopolysaccharides while the latter is a protein-polysaccharide complex. Both membranes provide support and chemical selectivity. The evidence for steroid activity in the follicle cells of these stages was inconclusive.

description: Lo svolgimento della tesi segue la falsariga del discorso tenuto da Pier Luigi Nervi a Torino nel maggio 1961 al momento dell’inaugurazione del Palazzo del Lavoro. In quell’occasione egli illustra la concezione strutturale del suo edificio, realizzato attraverso l’accostamento di 16 elementi autoportanti e indipendenti (ciascuno costituito da un grande pilastro in cemento armato a sezione variabile - da cruciforme a circolare - e da una piastra metallica di copertura) che gli permettono di coprire uno spazio di 25.000 mq come richiesto dal bando di concorso. 
Nel descrivere le varie parti dell’edificio e le modalità con cui si sono susseguite le differenti lavorazioni (attraverso fasi di cantiere attentamente pianificate), Nervi omette un particolare interessante. Esaminando i disegni esecutivi dell’opera si rileva che all’interno di ogni pilastro è presente una cavità che permette di percorrerlo dalla base fino alla sommità. Ad una prima osservazione questi ‘cunicoli nascosti’ ricordano quelli ricavati nelle spesse murature delle cattedrali romaniche o gotiche, all’interno delle quali si trovano scale a chiocciola che collegano la cripta alla copertura o alle intercapedini del sottotetto. Come per le cattedrali del passato, anche nel Palazzo del Lavoro la creazione di uno spazio praticabile interno alla struttura risponde a più requisiti: funzionale (la manutenzione dei pluviali e delle coperture), costruttivo (la riduzione del peso proprio della struttura) ed economico (il risparmio del materiale).
Nervi considera probabilmente questo dettaglio costruttivo un aspetto tecnico di minore importanza, appartenente cioè ad una dimensione ordinaria del proprio lavoro. Eppure, lo spazio ricavato all’interno del pilastro non coinvolge aspetti esclusivamente tecnici, ma sembra piuttosto nascere da una chiara visione progettuale che insegue un’idea di architettura, di unità, di organicità, di ‘servizio’ e di etica del mestiere.
Dall’osservazione dell’edificio e della documentazione di progetto se ne ricava infatti una differente considerazione: lo scavo del pilastro non costituisce un aspetto secondario e, viste le implicazioni di carattere spaziale che introduce, merita di essere compreso e approfondito alla luce dell’intera opera di Nervi.

description: The assessment of the RAMS (Reliability, Availability, Maintainability and Safety) performances of system generally includes the evaluations of the “Importance” of its components and/or of the basic parameters of the model through the use of the Importance Measures. The analytical equations proposed in this study allow the estimation of the first order Differential Importance Measure on the basis of the Birnbaum measures of components, under the hypothesis of uniform percentage changes of parameters. The aging phenomena are introduced into the model by assuming exponential-linear or Weibull distributions for the failure probabilities.
An algorithm based on a combination of MonteCarlo simulation and Cellular Automata is applied in order to evaluate the performance of a networked system, made up of source nodes, user nodes and directed edges subjected to failure and repair.
Importance Sampling techniques are used for the estimation of the first and total order Differential Importance Measures through only one simulation of the system “operational life”. All the output variables are computed contemporaneously on the basis of the same sequence of the involved components, event types (failure or repair) and transition times. The failure/repair probabilities are forced to be the same for all components; the transition times are sampled from the unbiased probability distributions or it can be also forced, for instance, by assuring the occurrence of at least a failure within the system operational life.
The algorithm allows considering different types of maintenance actions: corrective maintenance that can be performed either immediately upon the component failure or upon finding that the component has failed for hidden failures that are not detected until an inspection; and preventive maintenance, that can be performed upon a fixed interval. It is possible to use a restoration factor to determine the age of the component after a repair or any other maintenance action.

description: The study presented in this work deals with the  investigation  of the effects produced by two common techniques of static balancing on the dynamic performances of closed-chain linkages, taking into account the compliance of the mechanism components. The long-term goal of the research consists in determining an optimal balancing strategy for parallel spatial manipulators. 
The present contribution is a starting point and it focuses on the planar four-bar linkage, intended as the simplest example of closed-chain mechanism. The elastodynamic behaviour of an unbalanced four-bar linkage and two balanced ones, respectively obtained by mass and elastic balancing, is investigated by means of both numerical simulations and experimental tests. The purpose of this work  is to obtain preliminary results, to be refined and broadened in future developments

description: Self diffusion coefficients and binary Maxwell-Stefan diffusion coefficients were determined by equilibrium molecular dynamics simulations with the Green-Kubo method. The study covers five pure fluids: neon, argon, krypton, xenon, and methane and three binary mixtures: argon+krypton, argon+xenon, and krypton+xenon. The fluids are modeled by spherical Lennard-Jones air-potentials, with parameters which were determined solely on the basis of vapor-liquid equilibria data. The predictions of the self diffusion coefficients agree within 5% for gas state points and about 10% for liquid state points. The Maxwell-Stefan diffusion coefficients are predicted within 10%. A test of Darken's model shows good agreement.

description: Spider silks are incredible natural materials that have a wide variety of properties that can rival or outperform even common synthetic materials like Nylon and Kevlar. As nature’s architects, orb-weaving spiders spin seven different silks that are used for very specific roles throughout the spider’s lifecycle. These silks are comprised of proteins called spidroins. Each of these spidroins has evolved to have properties such as strength and/or stretch that make these silks successful and highly adapted in their designated roles in web construction, prey capture and reproduction.
This study involves the production of minor ampullate silk by genetically modifying the bacteria Escherichia coli. Minor ampullate is a lesser studied silk that is used for the first spiral of the orb web. This spiral is a template that the spider uses to finish the web and provides stability during the web construction. Minor ampullate silk is strong, however it does not stretch so it may be well-suited for certain applications such as ballistic materials.
By producing and purifying different arrangements of minor ampullate silk protein, it is possible to learn how this protein can be expressed without using the spider itself. This investigation sheds light on how deviations in the protein sequence and motif arrangement can produce different properties, which can potentially be used to make new materials.

description: Abstract

Solid waste generated by household, commercial and other economic consumption, solid waste handling and final destiny in the environment is very crucial, because its effect on public health can be devastating. The economic consumption behavior of consumers plays an important role in the quantity of solid waste generated. In present study, we analyzed the mode of solid waste generated by consumers and its effect on public health by using a questionnaire and recruiting 200 participants. Furthermore we determined the behavior of moderate and Israf consumers regarding solid waste generation. The aim of this study is to explore the effect of behavior of peoples and impact of Economic Consumption on Solid waste generation. Randomly selecting areas of Pakistan were explored to quantify the data about the waste generating habits, waste generation quantity and waste disposable methods by using a close-ended questionnaire. It was found that the frequency of conscious waste among participants is higher as compared to unconscious waste. It was observed that the frequency of commercial solid waste generated more as compared to household solid waste generated. The Mode of solid waste was studied in the current study and it was found that the mode of solid waste disposal frequency to hand over to collector higher as compared to burning of waste, disposal in streets openly and disposal in streets within bags. It was also found that the burning frequency of waste is more among participants as compared to throwing on dump. Frequencies of different common diseases (asthma, cholera, dysentery, eye infection conjunctivitis and COPD) were observed in the studied area to find out the association of diseases with mode of solid waste generation. It was observed that frequency of typhoid frequency is greater in overall studied area. The Present study explores the mode and behavior of waste generation is a very great risk to health and our environment. The Current study observed that household solid waste generated by moderate consumers and Israf consumer was significantly different as compared to waste generated at commercial places by moderate consumers and Israf consumers. A Positive correlation of seven types of pollution-related diseases was observed with open waste dumping resident participants.

description: Abstract

In recent years, the mathematics teaching has been a topic of increasing concern due to its foundational importance in shaping students' analytical and problem-solving skills. Despite its significance, teaching mathematics at the basic level is a challenge. Hence, this study is to identify the challenges by teacher when teaching mathematics at the basic level school. To cope with this challenges, three learning theories plays the crucial role where the children learn, process, and apply mathematics in real life situation. The analysis was based on six dimensions of the teachers’ demographic factors, such as gender, age, qualification, experience, training, and school type. The study highlighted the numerous challenges faced by basic-level mathematics teachers, including content delivery, student engagement, resource use, classroom management, assessments, and professional development. The multiple regression value, R square and the adjusted R square value for those variables was found to be 0.469, 0.220, and 0.0792 respectively. Addressing these challenges requires holistic support, resource enhancement, capacity building, and pedagogical innovation with improving instructional practices, and informing policy for effective mathematics education.

description: Les localisations buccales du lymphome de Burkitt sont rarement observées et rapportées dans la littérature chez les patients infectés par le VIH. Le tableau clinique peut évoquer d’autres tumeurs ou infections gingivales, ce qui retarde le diagnostic et la prise en charge. L’atteinte de la moelle épinière est rare, et seulement quelques cas sont rapportés dans la littérature. Nous rapportons un cas de lymphome de Burkitt gingival avec atteinte de la moelle épinière révélant l’infection à VIH chez une patiente âgée de 44 ans et qui a bien évolué sous chimiothérapie et traitement antirétroviral. Spinal cord compression secondary to metastasis of gingival Burkitt lymphoma revealing a case of HIV infection in Morocco Burkitt lymphoma in HIV-infected patients is seldom seen in the oral cavity, and they are rarely reported in the literature. The clinical manifestations may suggest other tumors or gingival infections, which delays diagnosis and management. Spinal cord involvement is exceptional and only a few cases are reported. We report a case of Burkitt lymphoma in the oral cavity and spinal cord, revealing HIV infection in a 44-year-old patient, who responded well to chemotherapy and antiretroviral treatment and is on remission.
