Objectives
The present study analyzed the psychological well-being of adults diagnosed with asthma in comparison to adults without asthma. It was postulated that adults with and without asthma will significantly differ in respect to psychological well-being (autonomy, environmental mastery, personal growth, positive relation with others, purpose in life and self-acceptance).

Methodology
The present comparative research was carried out over the period of six months. Total 120 participants were recruited for the present purpose including sixty (n = 60) adults diagnosed with asthma and sixty (n=60) without asthma. Data collection was done using demographic information form and Psychological Well-being Scale (42-items). Data was analyzed by computing independent samples t-test through SPSS Version, 22.0.

Results
Statistical analysis depicted a significant difference among adults with and without asthma in respected to in relation to environmental mastery (t = -3.59, df = 118, p = 0.000), personal growth (t = -4.40, df= 118, p = .000), positive relations with others (t = -2.59, df = 118 , p = .011 ), purpose in life ( (t = -5.46 , df = 118, p = .000 ), self-acceptance (t = -2.26 , df = 118, p = 0.025 ) and psychological well-being (t = - 4.932, df = 118, p = 0.000). A non-significant difference was found out among adults on the variable of autonomy (t = -1.42, df = 118, p = 0.156).
Conclusion
Psychological well-being of adults is significantly influenced by asthma in terms of environmental mastery, personal growth, positive relations with others, purpose in life and self-acceptance.
“Colonialismo” y “vínculo telúrico” en la obra de Carlos Astrada
Authors: Bustos Nora Andrea 
Published: May 2024

El presente artículo se propone rastrear en la obra de Carlos Astrada los conceptos de “colonialismo” y “vínculo telúrico”. Para ello haremos una exégesis del libro El mito gaucho, publicado en el año 1948, en donde nuestro autor realiza una filosofía de la argentinidad a la luz de su interpretación del Martín Fierro en el momento de esplendor del gobierno de Perón. Luego interpretaremos las obras que datan de su alejamiento del peronismo y su interés por la filosofía latinoamericana, tales como “Mito, tiempo e historicidad”, en donde nuestro autor comienza a mostrar sus análisis en torno a otras piezas literarias como el Chilam Balam de la cultura maya, y su conferencia titulada “La filosofía latinoamericana como exponente de una cultura autónoma”, en donde plantea la necesidad de una emancipación del pensamiento europeo. En esa línea analizaremos el texto El marxismo y las escatologías, de 1957 donde reconoce la importancia del calendario azteca y del Popol Vuh. Ya para 1963, cuando publica Tierra y figura, encontramos la ampliación de su horizonte desde la pampa hacia la selva y los andes. En el análisis de la segunda edición de El mito gaucho mostraremos cómo aboga por la construcción de una gauchocracia comunitaria. Finalmente, daremos cuenta del modo en que muchos de estos conceptos han sido tematizados por la siguiente generación de filósofos, en especial los que conformaron el movimiento denominado “Filosofía de la liberación”.

Published: May 2024

Обращение к теоретическим основаниям изучения основных вузовских обра- зовательных общностей связано с необходимостью поиска способа решения проблем разрозненности вузовских образовательных общностей в сфере науч- ной деятельности. Необходимость изучения взаимодействия вузовских образователь- ных общностей определила цель статьи — анализ теоретического каркаса изучения вузовских образовательных общностей и основной метод — анализ теорий среднего уровня, описывающих функционирование вузовских образовательных общностей, ор- ганизации их научной деятельности, исследовательских практик и способов взаимо- действия в научном пространстве. На этом основании предлагаются интерпретации ключевых терминов концепции оптимального взаимодействия вузовских образователь- ных общностей в университетском научном пространстве: научного капитала, научно-образовательной деятельности, общностей научно-педагогических работников, студен- чества, административно-управленческих работников. Делается вывод о необходимости их дальнейшего изучения с позиций их действия и взаимодействия как самостоятель- ной научной задачи.
Turning to the theoretical foundations of studying the main university educational communities is associated with the need to find a way to solve the problems of fragmentation of university educational communities in the field of scientific activity. The need to study the interaction of university educational communities was determined by the purpose of the article — the analysis of the theoretical framework for the study of university educational communities and the main method — the analysis of middle-level theories that describe the functioning of university educational communities, the organization of their scientific activities, research practices and methods of interaction in the scientific space. On this basis, interpretations of the key terms of the concept of optimal interaction between university educational communities in the university scientific space are proposed: scientific capital, scientific and educational activities, communities of scientific and pedagogical workers, students, administrative and managerial workers. The conclusion is made about the need for their further study from the standpoint of their action and interaction as an independent scientific task.

Published: May 2024

Sown mixed grassland is rarely used for livestock raising and grazing; however, different forages can provide various nutrients for livestock, which may be beneficial to animal health and welfare. We established a sown mixed grassland and adopted a rotational grazing system, monitored the changes in aboveground biomass and sheep weights during the summer grazing period, measured the nutrients of forage by near-infrared spectroscopy, tested the contents of medium- and long-chain fatty acids by gas chromatography, and explored an efficient sheep fattening system that is suitable for agro-pastoral interlacing areas. The results showed that the maximum forage supply in a single grazing paddock was 4.6 kg DM/d, the highest dry matter intake (DMI) was 1.80 kg DM/ewe/d, the average daily weight gain (ADG) was 193.3 g, the DMI and ADG were significantly correlated (P < 0.05), and the average feed weight gain ratio (F/G) reached 8.02. The average crude protein and metabolizable energy intake by sheep were 286 g/ewe/d and 18.5 MJ/ewe/d respectively, and the n-6/n-3 ratio of polyunsaturated fatty acids in mutton was 2.84. The results indicated that the sheep fattening system had high feed conversion efficiency, could improve the yield and quality of sheep, and could be promoted in suitable regions.

Authors: Andam Emmanuel Appoh , Folson Derick , Adu Augustina 
Published: May 2024

This paper presents Po-Shen Loh’s method as an alternate method for solving quadratic equations, which is seen as an efficient and natural method for solving general quadratic equations. The study is an action research involving a sample of forty – five (45) students of Kumasi Wesley Girls High School, randomly selected for the study. Prior to the study, it was observed that the students did not know about any other method of solving quadratic equation other than the four traditional methods (factorisation, formula, completing squares and graphical) in the mathematics curriculum at the senior high school level in Ghana. The pre-test and post-test scores obtained by the students were analysed quantitatively and an inferential and descriptive analysis were performed. Comparatively, the scores obtained from the pre-test and post-test showed a significant improvement in the students’ ability to solve quadratic equations using the Po-Shen Loh’s method. The authors therefore recommend for it to be introduced into the senior high school mathematics curriculum in Ghana.

Authors: Jones Elizabeth A. , Stewart Alison , Stiller Charles , Douglas Fiona , Bown Nick 
Published: August 2011

AbstractThree individuals with chromosome 2q terminal deletions have been reported in the medical literature to have developed Wilms tumor. By looking at a UK national cohort, we aimed to ascertain the chance of an individual with a 2q terminal deletion developing a Wilms tumor. The objective was to clarify screening recommendations. All individuals over a 40‐year period with chromosome 2q terminal deletions were ascertained from the Chromosome Abnormality Database. The names and dates of birth of these individuals were obtained from the Regional Cytogenetic Departments where the original chromosome analyses were performed. These data were collated and compared with the National Registry of Childhood Tumors. One hundred twenty‐nine subjects were identified over a 40‐year study period. Only a single individual in our national cohort was affected by Wilms tumor. This individual had an add(2)(q35) karyotype. We conclude that the incidence of Wilms tumor in the majority of individuals with a 2q terminal deletion is low, and is below the recommended threshold for surveillance for tumor development. © 2011 Wiley‐Liss, Inc.
Complex Intermetallic Compounds: CaNi5Ge3, Ca15Ni68Ge37, and Ca7Ni49Ge22 – Three Multifaceted Ni‐Ge Framework Structures Combining the Structural Motifs of Ni3Ge and CaNi2Ge2

Published: August 2011

AbstractThe intermetallic compounds, CaNi5Ge3, Ca15Ni68Ge37, and Ca7Ni48.9(4)Ge22.1(4), were prepared by arc‐melting of the elements and subsequent heating in welded tantalum ampoules. The compounds were investigated by powder and single‐crystal X‐ray diffraction methods. Each of the three compounds crystallized in a different structure type, namely, CaNi5Ge3 in the space group P4/mbm, a = 8.0855(1) Å, c = 7.8466(1) Å, wR2 = 0.054, 439 F2 values, 31 variable parameters; Ca15Ni68Ge37 in the space group P$\bar {6}$2m, a = 22.436(2) Å, c = 3.9684(4) Å, wR2 = 0.096, 1849 F2 values, 133 variable parameters; Ca7Ni48.9(4)Ge22.1(4) in the space group P6/mmm, a = 17.381(4) Å, c = 4.046(1) Å, wR2 = 0.082, 693 F2 values, 59 variable parameters. The crystal structures consist of complex 3D networks of nickel and germanium atoms that have common motifs, namely, different sections of the Ni3Ge structure, as well as, Ca‐centered hexagonal prisms of Ni and Ge, which have been observed in the CaNi2Ge2 structure. As the Ca content decreases, the Ni‐Ge substructures form one‐, two‐, and three‐dimensional networks. The disorder in Ca7Ni48.9(4)Ge22.1(4) is explained by a structural frustration. The electronic structure and chemical bonding of CaNi5Ge3 is discussed by means of band‐structure calculations.

AbstractCancer of the oral cavity is a serious disease, affecting about 30,000 individuals in US annually. There are several animal models of oral cancer, but each has certain disadvantages. As a new model, we investigated whether topical application of the tobacco smoke carcinogen, dibenzo[a,l]pyrene (DB[a,l]P) is mutagenic and carcinogenic in the oral cavity of the B6C3F1 lacI and B6C3F1 mouse, respectively. B6C3F1 lacI mice received DB[a,l]P (0, 3, 6, 12 nmol) 3× per week. B6C3F1 mice received the same doses and also 24 nmol. At 38 weeks mutagenesis was measured in oral tissues in lacI mice. For the high dose group, the mutant fraction (MF) in upper mucosa and tongue increased about twofold relative to that in vehicle‐alone. The increases were statistically significant. The mutational profile in the DB[a,l]P‐induced mutants was compared with that induced by benzo[a]pyrene (BaP) in oral tissue. BaP is mutagenic in many tissues when administered by gavage. The mutational profile for DB[a,l]P was more similar to that reported for p53 mutations in head and neck cancers than was that of BaP. At 47 weeks, oral squamous cell carcinomas (OSCC) were found in 31% of the high‐dose B6C3F1 group. Elevations of p53 and COX‐2 protein were observed in tumor and dysplastic tissue. As DB[a,l]P induces mutations and tumors in the oral cavity, and has a mutational profile in oral tissue similar to that found in p53 in human OSCC, the treatment protocol described here may represent a new and relevant model for cancer of the oral cavity.

Published: August 2011

AbstractNew crown ether carrying two fluorionophores of cis‐dibenzothiazolyldibenzo‐24‐crown‐8 was synthesized from cis‐diformyldibenzo‐24‐crown‐8 and 2‐aminobenzenethiol. The binding behavior and the optical properties of the crown ether were examined through UV‐visible spectroscopy and fluorescence spectroscopy. When complexed with Na+, K+, Rb+, and Cs+ ions, it led to intramolecular charge transfer and caused the changes of the fluorescence spectra. The protonation of the crown ether was also studied. With protonation using CF3COOH, the absorption bands and the fluorescence spectroscopy changed, the maximal fluorescence wavelengths red shifted and the fluorescence intensity with the maximum at 433 nm enhanced strongly.

AbstractThe increasing clinical incidence and host risk of open fracture‐associated infections, as well as the reduced effectiveness of conventional antibiotics to treat such infections, have driven the development of new therapies for the prophylaxis of open fracture‐associated infections. We investigated percutaneous supplementation of a natural cytokine (i.e., interleukin 12p70 or IL‐12) at an open fracture site to reduce open fracture‐associated infections. We also determined the efficacy of the combination therapy of IL‐12 and conventional antibiotic therapy in the prophylaxis of open fracture‐associated infections. An open femur fracture infection model was produced by direct inoculation of a clinical isolate of Staphylococcus aureus after creating a femur fracture using rats. The animals were assigned to one of four groups: no drug administration, percutaneous supplementation of IL‐12, intraperitoneal administration of the antibiotic ampicillin, or percutaneous IL‐12 in combination with intraperitoneal ampicillin. Animals were euthanized at postoperative days 6, 10, 14, and 21. Percutaneous IL‐12 led to a reduction in infection at postoperative days 6 and 10. For the first time, exogenous IL‐12 was found to have additive effects in the prevention of infection when combined with conventional treatment (i.e., antibiotic therapy). Combination therapy of ampicillin and IL‐12 substantially reduced the infection rate at postoperative day 6 and also decreased the time needed for complete inhibition of infection. Therefore, exogenous IL‐12, providing a mechanism of protection independent of antibiotic resistance, complements the routine use of antibiotics. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

AbstractWe used item response theory (IRT) to (a) investigate the dimensionality of the Symptom Checklist‐90‐Revised (SCL‐90‐R) in a severely disturbed patient group, (b) improve the subscales in a meaningful way and (c) investigate the measurement precision of the improved scales. The total sample comprised 3078 patients (72% women, mean age = 35 ± 9) admitted to 14 different day hospitals participating in the Norwegian Network of Personality‐focused Treatment Programmes. Mokken Scale Analysis was used to investigate the dimensionality of the SCL‐90‐R and improve the subscales. This analysis was theory‐driven: the scales were built on two start items that reflected the content of the disorder that corresponds with the specific scale. The Graded Response Model was employed to determine measurement precision. Our theory‐driven IRT approach resulted in a new seven‐factor solution including 60 of the 90 items clustered in seven scales: depression, agoraphobia, physical complaints, obsessive‐compulsive, hostility (unchanged), distrust and psychoticism. Most of the new scales discriminated reliably between patients with moderately low scores to moderately high scores. In conclusion, we found support for the multidimensionality of the SCL‐90‐R in a large sample of severely disturbed patients. Copyright © 2011 John Wiley & Sons, Ltd.
The functional microstructure of tendon collagen revealed by high‐field MRI
Authors: Mountain Kelsey M. , Bjarnason Thorarin A. , Dunn Jeff F. , Matyas John R. 
Published: August 2011

AbstractT2 was used in this study to assess tendon microstructure. Two unloaded digital extensor tendons were bent such that their long axes were imaged throughout 180° with respect to B0. T2‐weighted images reveal periodic banding (∼200 μm) when tendons were oriented at ±55° with respect to B0. Five pairs of tendons were used to study the influence of load on T2W MRI: one tendon of each pair was loaded with a 7.8‐N mass, and both tendons were fixed in formalin then imaged at 55° to B0. MRI banding was present in the unloaded, but not loaded, tendons. In unloaded tendons, polarized‐light microscopy revealed collagen crimp with a periodicity similar to MRI. In loaded tendons, there was a strain‐induced extinction of periodicity on both MRI and polarized‐light microscopy. These studies confirm that crimp is detectable by high‐field MRI and could serve as an in vivo index of physiological strains in collagenous tissues. Magn Reson Med, 2011. © 2011 Wiley‐Liss, Inc.
Thieno[3,4‐b]pyrazine‐based low bandgap photovoltaic copolymers: Turning the properties by different aza‐heteroaromatic donors
Authors: Peng Qiang , Liu Xiangju , Qin Yuancheng , Zhou Dan , Xu Jun 
Published: August 2011

AbstractA new series of low‐bandgap copolymers based on electron‐accepting thieno[3,4‐b]pyrazine (TPZ) and different electron‐donating aza‐heteroaromatic units, such as carbazole (CZ), dithieno[3,2‐b:2′,3′‐d]pyrrole (TPR) and dithieno[3,2‐b:2′,3′‐e]pyridine (TPY), have been synthesized by Suzuki or Stille coupling polymerization. The resulting copolymers were characterized by NMR, elemental analysis, gel permeation chromatography, thermogravimetric analysis, and differential scanning calorimetry. UV–vis absorption and cyclic voltammetry measurements show that TPZ‐based copolymer with TPR has the best absorption due to the strongest intramolecular charge transfer effect and smallest bandgap. The basic electronic structure of D‐A model compounds of these copolymers were also studied by density functional theory (DFT) calculations. The conclusion of calculation agreed also well with the experimental results. The polymer solar cells (PSCs) based on these copolymers were fabricated with a typical structure of ITO/PEDOT:PSS/copolymer:PC71BM/Ca/Al under the illumination of AM 1.5G, 100 mW cm−2. The performance results showed that TPZ‐based copolymer with TPR donor segments showed highest efficiency of 1.55% due to enhanced short‐circuit current density. The present results indicate that good electronic, optical, and photovoltaic properties of TPZ‐based copolymers can be achieved by just fine‐tuning the structures of aza‐heteroaromatic donor segments for their application in PSCs. © 2011 Wiley Periodicals, Inc.

SEDIMENT DYNAMICS IN THE RESTORED REACH OF THE KISSIMMEE RIVER BASIN, FLORIDA: A VAST SUBTROPICAL RIPARIAN WETLAND
Authors: Schenk E. R. , Hupp C. R. , Gellis A. 
Published: August 2011

ABSTRACTHistorically, the Kissimmee River Basin consisted of a broad nearly annually inundated riparian wetland similar in character to tropical Southern Hemisphere large rivers. The river was channelized in the 1960s and 1970s, draining the wetland. The river is currently being restored with over 10 000 hectares of wetlands being reconnected to 70 river km of naturalized channel. We monitored riparian wetland sediment dynamics between 2007 and 2010 at 87 sites in the restored reach and 14 sites in an unrestored reference reach. Discharge and sediment transport were measured at the downstream end of the restored reach. There were three flooding events during the study, two as annual flood events and a third as a greater than a 5‐year flood event. Restoration has returned periodic flood flow to the riparian wetland and provides a mean sedimentation rate of 11.3 mm per year over the study period in the restored reach compared with 1.7 mm per year in an unrestored channelized reach. Sedimentation from the two annual floods was within the normal range for alluvial Coastal Plain rivers. Sediment deposits consisted of over 20% organics, similar to eastern blackwater rivers. The Kissimmee River is unique in North America for its hybrid alluvial/blackwater nature. Fluvial suspended‐sediment measurements for the three flood events indicate that a majority of the sediment (70%) was sand, which is important for natural levee construction. Of the total suspended sediment load for the three flood events, 3%–16% was organic and important in floodplain deposition. Sediment yield is similar to low‐gradient rivers draining to the Chesapeake Bay and alluvial rivers of the southeastern USA. Continued monitoring should determine whether observed sediment transport and floodplain deposition rates are normal for this river and determine the relationship between historic vegetation community restoration, hydroperiod restoration, and sedimentation.

Connectionist modelling of skill dynamics
Authors: Ridsdale Gary 
Published: August 2011

AbstractThis paper discusses a method for modelling skilled action for synthetic actors in a virtual environment. The method guides lower‐level motor skills from a connectionist model of skill memory, implemented as collections of trained neural networks. The relationship between this work and that of other projects in task‐level animation is discussed, the principles of connectionist learning are explained, and a series of experiments testing the concept of connectionist skill modelling are reviewed.
