Abstract:

Abstract The article analyses the basic issues of procedural methods for evaluating the environment affected by the exploitation of mineral resources. The paper deals with the area, which was affected by black coal extraction already in the last century and is located in the area of Orlová-Poruba. Tthe first part explicates the basic concepts of landscape restoration issues, views of the methods of assessment and evaluation of the environment and related negative and positive externalities incurred. Another part of this paper assesses the affected area using the so-called Hessian method. Finally, we assess possible solutions of the evaluation of mostly positive externalities ocurred under the conditions in the Czech Republic and the desirability of the proposed new methodology for environmental assessment, including possible solutions.

Abstract:

Abstract One of the most serious risks associated with mining using mainly underground methods is the risk of mine fires. Causes of these fires can be exogenous (external) or endogenous (internal). The authors of the article pay attention to endogenous fires in coal mines, especially to the timely indication of them. As already mentioned in many contributions, spontaneous combustion is a complicated process that passes, in the final stage, into a mine open fire. The localization of a place of such danger can be done by means of so-called indicator gases that are desorbed from the coal substance at a point of the originating seat of spontaneous combustion. The article deals with a development trend in the use of indicator gases for spontaneous combustion in coal mining. The objective of the authors was to arrange chronically and briefly knowledge of the use of indicator gases both abroad and in the Czech Republic and to provide input information about a research project being dealt with at present

Abstract:

Mikropolutanty v životním prostředí působí negativně na vodní ekosystémy a též představují potenciální riziko pro lidské zdraví. Zásadním zdrojem vnosu mikropolutantů do životního prostředí jsou městské ČOV, jejichž konvenční mechanicko-biologická technologie není na odstraňování mikropolutantů navržena. V této práci jsme testovali účinnost odstranění mikropolutantů řadou oxidačních (např. ozonizace, UV/H2O2, Fentonova reakce, borem dopovaná diamantová elektroda) a sorpčních (např. granulované aktivní uhlí GAU, zeolity) procesů. Účinnost odstranění vybraných léčiv (např. erythromycin, sulfamethoxazol, ibuprofen atd.) a metabolitů pesticidů (např. acetochlor ESA, metazachlor ESA) jsme testovali v jednorázových vsádkových testech. S přihlédnutím k ekonomickým i provozním parametrům byla pro následné testování v reálných podmínkách (poloprovozní měřítko) zvolena kombinace oxidace UV/H2O2 a sorpce na GAU. Mikropolutanty v modelové vodě byly úspěšně odstraněny z 91% (suma léčiv) a cca 100% (suma metabolitů pesticidů) při použití optimální dávky H2O2 5 mg/l a intenzity UV záření 4 kJ/m2 s následnou sorpcí na GAU. Tyto velmi slibné výsledky v současné době ověřujeme v pilotní jednotce pro dočištění reálného odtoku z městské ČOV. Abstract (EN) Micropollutants cause harm to aquatic ecosystems and can also negatively affect human health. Major sources of micropollutants input to aquatic environments are wastewater treatment plants due to their insufficient removal during the conventional mechanical-biological process. This study aimed to evaluate potential WWTP effluent post-treatment processes for the removal of selected pharmaceuticals and pesticides using oxidation (e.g., ozonization, UV/H2O2, Fenton, boron-doped diamond electrode) and sorption (e.g. granular activated carbon, zeolite) processes and their combinations. The removal of selected pharmaceuticals (e.g. erythromycin, sulphamethoxazole, ibuprofen) and pesticides (e.g. acetochlor ESA, metazachlor ESA) was tested in batch assays. The combination of UV/H2O2 and activated carbon adsorption was the most favorable in terms of removal efficiency and economic and operational parameters. This combination achieved the removal efficiencies of pharmaceuticals and pesticides of 91 and 100%, respectively, using an optimum H2O2 dose of 5 mg/L and UV intensity of 4 kJ/m2 followed by granular activated carbon adsorption. These promising results are currently adopted in a pilot-scale study for the post-treatment of a real WWTP effluent.

Abstract:

SummaryReviewing three important recently published volumes on Pentateuch criticism, Torsten Uhlig highlights their merits and limits, evaluates their contribution to the interpretation of the Pentateuch and summarises some of the central issues that Pentateuch studies need to address. Among them, he raises the issue of integrating diachronic studies and narrative approaches. Moreover, while previous evangelical contributions to Pentateuch studies often focused on aspects of unity, Uhlig indicates the merits of acknowledging and integrating the diversities in a narratological approach. He concludes with some hermeneutical reflections that also interrelate with other disciplines of theology.ZusammenfassungTorsten Uhlig stellt drei wichtige kürzlich publizierte Aufsatzsammlungen zur Pentateuchkritik vor und arbeitet ihre Verdienste ebenso wie einige Grenzen heraus. Er bewertet ihren Beitrag für die Interpretation des Pentateuchs und fasst einige zentrale Aufgaben zusammen, die der Behandlung in Studien zum Pentateuch bedürfen. Darunter zählt er die Notwendigkeit der Integration von diachronen und narrativen Ansätzen. Gegenüber früheren evangelikalen Beiträgen zur Interpretation des Pentateuchs, deren vorrangiges Augenmerk auf dessen Einheit lag, weist Uhlig auf die Chancen hin, die Differenzen im Rahmen eines narrativen Ansatzes ernst zu nehmen und zu integrieren. Er beschließt seinen Aufsatz mit einigen hermeneutischen Überlegungen, die auch zu anderen Disziplinen der Theologie in einer wechselseitigen Beziehung stehen.RésuméTorsten Uhlig fait la recension de trois anthologies importantes récemment publiées traitant de la critique du Pentateuque. Il présente leurs mérites et leurs limites, évalue leur contribution à l’interprétation du Pentateuque et résume certaines des questions centrales que les études sur le Pentateuque doivent aborder. Parmi celles-ci, il mentionne le problème de l’intégration des études diachroniques et des approches narratives. En outre, alors que les contributions évangéliques antérieures ont surtout insisté sur des aspects de l’unité, Uhlig montre l’intérêt qu’il y a à reconnaître et intégrer les diversités dans une approche narratologique. Il conclut par quelques réflexions herméneutiques qui ont aussi une portée pour d’autres disciplines théologiques.

Abstract:

Children with minimal/mild bilateral hearing loss (MBHL) or unilateral hearing loss (UHL) are at risk for academic, speech/language, and social/emotional difficulties, and the provision of FM is a standard recommendation. In this article, various topics relating to FM use by children with MBHL/UHL are discussed. First, the difficulties that some children with MBHL/UHL experience are reviewed. A discussion ensues on the use of FM systems by children with MBHL/UHL and what choices could be considered. Ultimately, each child must be evaluated individually for use of an FM system, as there is no “one size fits all” solution to their communication difficulties. Finally, tips on communicating with children who have MBHL/UHL are reviewed.

Abstract:

This study investigated the effects of unilateral hearing loss (UHL), of either conductive or sensorineural origin, on stereo sound localization and related visual bias in listeners with normal hearing, short-term (acute) UHL, and chronic UHL. Time-delay-based stereophony was used to isolate interaural-time-difference cues for sound source localization in free field. Listeners with acute moderate (<40 dB for tens of minutes) and chronic severe (>50 dB for more than 10 years) UHL showed poor localization and compressed auditory space that favored the intact ear. Listeners with chronic moderate (<50 dB for more than 12 years) UHL performed near normal. These results show that the auditory spatial mechanisms that allow stereo localization become less sensitive to moderate UHL in the long term. Presenting LED flashes at either the same or a different location as the sound source elicited visual bias in all groups but to different degrees. Hearing loss led to increased visual bias, especially on the impaired side, for the severe and acute UHL listeners, suggesting that vision plays a compensatory role in restoring perceptual spatial symmetry.

Abstract:

Background: Disrupted binaural hearing is thought to contribute in part to the academic, social, and communication problems often associated with unilateral hearing loss (UHL) in childhood. It is not known, however, if putting a hearing aid in the impaired ear of a child with UHL will lead to bilateral or binaural benefit. This study seeks to utilize sound localization acuity measurements to assess hearing aid amplification efficacy in children with UHL. Purpose: To measure sound localization ability in children with UHL who use a hearing aid in the impaired ear to determine the extent to which amplification, age, early intervention, and degree of hearing loss affects localization acuity. Research Design: A within-subjects experimental design using repeated measures is used to determine the effect of amplification on localization acuity in children with UHL. A between-subjects experimental design is used to compare localization acuity between children with UHL and age-matched controls with normal hearing. Study Sample: Twelve children with UHL who used a hearing aid in the impaired ear and 12 age-matched controls with normal hearing. Children with UHL were divided into two groups based on degree of hearing loss. Children in both groups were divided into two age groups: older children (10–14 yr) and younger children (6–9 yr). Data Collection and Analysis: All testing was done in a sound-treated booth with a horizontal array of 15 loudspeakers (radius of 1 m). The stimulus was a spondee word, “baseball”: the level averaged 60 dB SPL and randomly roved (±8 dB). Each child was asked to identify the location of a sound source. Results: In the experimental study a significant interaction was found between hearing aid amplification and child age. A hearing aid significantly improved localization acuity in younger children with UHL and significantly impaired localization acuity in older children. A significant correlation was found between age at intervention and localization bilateral benefit. Children who were fit earlier showed bilateral benefit whereas children who were fit later showed bilateral interference. Development, however, may play a role in sound localization acuity. When unaided, older children had significantly better localization acuity than younger children with UHL. Conclusions: A hearing aid can provide bilateral localization benefit to some children with UHL. Early intervention may increase the likelihood of bilateral benefit. However, developmental factors appear to play a role in improving localization abilities over time for children with UHL. Nonetheless, without a means of establishing bilateral benefit with hearing aid amplification, localization performance in children with UHL will rarely equal that of peers.

Abstract:

Purpose The purpose of this study was to measure auditory comprehension performance in school-aged children with unilateral hearing loss (UHL) and with normal hearing (NH) in quiet and in the presence of child-produced two-talker babble (TTB). Method Listeners were school-aged children (7–12 years) with permanent UHL ( n = 25) or NH ( n = 14). Comprehension of three short stories taken from the Test of Narrative Language ( Gillam & Pearson, 2004 ) was measured in quiet and in the presence of TTB at two signal-to-noise ratios (SNRs): (a) +6 dB and (b) the individualized SNR required to achieve 50% sentence understanding in the presence of the same TTB masker in a prior study ( Griffin, Poissant, & Freyman, 2019 ). Target/masker spatial configuration was 0°/±60° azimuth. Results As a group, subjects with UHL demonstrated auditory comprehension abilities in favorable listening environments (i.e., quiet, +6 dB SNR) that were statistically equivalent to the NH group. However, in the most challenging listening condition (individualized SNR), many subjects with UHL demonstrated poorer comprehension performance than their age-matched peers with NH. Comprehension abilities were not associated with degree of UHL, unaided speech intelligibility index at 65 dB SPL in the impaired ear, side of UHL, or sex. Conclusions As a group, children with UHL demonstrated deficits in auditory comprehension compared to age-matched peers with NH in challenging listening environments. Findings highlight the importance of ensuring good SNRs for children with UHL.

Abstract:

The study objective was to quantify abilities of children with unilateral hearing loss (UHL) on measures that address known deficits for this population, i.e. speech understanding in quiet and noise, and sound localisation. Noise conditions varied by noise type and source location. Parent reports of real-world abilities were also obtained. Performance was compared to gender- and age-matched normal hearing (NH) peers. UHL performance was poorer and more varied compared to NH peers. Among the findings, age correlated with localisation ability for UHL but not NH participants. Low-frequency hearing in the better ear of UHL children was associated with performance in noise; however, there was no relation for NH children. Considerable variability was evident in the outcomes of children with UHL and needs to be understood as future treatment options are considered.

Abstract:

Unilateral hearing loss (UHL) in children is only recently beginning to be widely appreciated as having a negative impact. We now understand that simply having one normal-hearing ear may not be sufficient for typical child development, and leads to impairments in speech and language outcomes. Unfortunately, UHL is not a rare problem among children in the United States, and is present among more than 1 out of every 10 of adolescents in this country. How UHL specifically affects development of speech and language, however, is currently not well understood. While we know that children with UHL are more likely than their normal-hearing siblings to have speech therapy and individualized education plans at school, we do not yet understand the mechanism through which UHL causes speech and language problems. The objective of this review is to describe what is currently known about the impact of UHL on speech and language development in children. Furthermore, we discuss some of the potential pathways through which the impact of unilateral hearing loss on speech and language might be mediated.

Abstract:

AbstractA unilateral hearing loss (UHL) can have a significant functional and social impact on children and adults, affecting their quality of life. In adults, UHL is typically associated with difficulties understanding speech in noise and sound localization, and UHL increases the self-perception of auditory disability for a range of listening situations. Furthermore, despite evidence for the negative effects of reduced unilateral auditory input on the neural encoding of binaural cues, the perceptual consequences of these changes are still not well understood.Determine effects of UHL on auditory abilities and speech-evoked cortical auditory evoked potentials (CAEPs).CAEPs, sound localization, speech perception in noise and self-perception of auditory abilities (speech, spatial, and qualities hearing scale) were assessed.Thirteen adults with UHL with a range of etiologies, duration of hearing loss, and severity and a control group of eleven binaural listeners with normal hearing.Participants with UHL varied greatly in their ability to localize sound and reported speech recognition and listening effort were the greatest problem. There was a greater effect of right ear than left ear hearing loss on N1 amplitude hemispheric asymmetry and N1 latencies evoked by speech syllables in noise. As duration of hearing loss increased, contralateral dominance (N1 amplitude asymmetry) decreased. N1 amplitudes correlated with speech scores, larger N1 amplitudes were associated with better speech recognition in noise scores. N1 latencies are delayed (in the better ear) and amplitude hemisphere asymmetry differed across UHL participants as function of side of deafness, mainly for right-sided deafness.UHL affects a range of auditory abilities, including speech detection in noise, sound localization, and self-perceived hearing disability. CAEPs elicited by speech sounds are sensitive enough to evidence changes within the auditory cortex due to an UHL.

Abstract:

Neuroplasticity following bilateral deafness and auditory restoration has been repeatedly investigated. In clinical practice, however, a significant number of patients present a severe-to-profound unilateral hearing loss (UHL). To date, less is known about the neuroplasticity following monaural hearing deprivation and auditory input restoration. This article provides an overview of the current research insights on the impact of UHL on the brain and the effect of auditory input restoration with a cochlear implant (CI). An exhaustive systematic review of the literature was performed selecting 38 studies that apply different neural analyses techniques. The main results show that the hearing ear becomes functionally dominant after monaural deprivation, reshaping the lateralization of the neural network for auditory processing, a process that can be considered to influence auditory restoration. Furthermore, animal models predict that the onset time of UHL impacts auditory restoration. Hence, the results seem to advocate for early restoration of UHL, although further research is required to disambiguate the effects of duration and onset of UHL on auditory restoration and on structural neuroplasticity following UHL deprivation and restoration. Ongoing developments on CI devices compatible with Magnetic Resonance Imaging (MRI) examinations will provide a unique opportunity to investigate structural and functional neuroplasticity following CI restoration more directly.

Abstract:

Alfred, Dvořåk's first opera, has long hovered at the edge of our awareness of the composer. If there are signs of a growing realization that opera was to Dvořåk quite as important as other areas of his output, the detail needed to flesh out the picture of ‘Dvořåk the opera composer’ is to a large extent lacking. In the case of the composer's first six operas the inaccessibility of material has meant that an assessment of his early work in the area is still very much the province of specialist scholars. Published vocal scores exist for only three of these early operas, and none of them are in any sense scholarly editions; in the case of Krål a uhlíř (King and Charcoal-Burner) the available edition is of a revision of the score made 13 years after the work was composed, with an entirely recomposed final act. Vanda, the fascinating first version of Krål a uhlíř, and Alfred remain unpublished, although a vocal score of Krål a uhlíř has been submitted to the Czech publishing house Artia.

Abstract:

A retrospective review of children with confirmed hearing loss identified through universal newborn hearing screening (UNHS) in Virginia from 2010 to 2014 was conducted in order to compare the incidence of Joint Committee on Infant Hearing (JCIH) risk factors in children with unilateral hearing loss (UHL) to bilateral hearing loss (BHL). Over the 5-year study period, 1004 children (0.20% of all births) developed a confirmed hearing loss, with 544 (51%) children having at least one JCIH risk factor. Overall, 18% of children with confirmed hearing loss initially passed UNHS. Of all children with risk factors, 226 (42%) demonstrated UHL and 318 (58%) had BHL. The most common risk factors for UHL were neonatal indicators (69%), craniofacial anomalies (30%), stigmata of HL syndromes (14%), and family history (14%). The most common risk factors in BHL were neonatal indicators (49%), family history (27%), stigmata of HL syndromes (19%), and craniofacial anomalies (16%). Children with the risk factor for positive family history were more likely to have BHL, while those with craniofacial anomalies were more likely to have UHL ( P < .001). Neonatal indicators were the most commonly identified risk factor in both UHL and BHL populations. Children with UHL were significantly more likely to have craniofacial anomalies, while children with BHL were more likely to have a family history of hearing loss. Further studies assessing the etiology underlying the hearing loss and risk factor associations are warranted.

Abstract:

Las áreas de almacenamiento son recurrentes en todos los palacios de Chan Chan, siendo los depósitos las estructuras de mayor importancia en el acúmulo de recursos. Mediante los resultados obtenidos en las investigaciones arqueológicas en los palacios Chayhuac, Uhle, Bandelier, Gran Chimú, Tschudi y Rivero, es posible conocer los diferentes tamaños y tipos de los depósitos. El tipo de almacenaje dependió de la naturaleza del objeto, usando o no recipientes para tal fin, pero posiblemente fue prioridad el almacenamiento de granos, como frejoles, maní y maíz, siendo este último parte fundamental de la dieta y la materia prima para la elaboración de la chicha. Los depósitos en la capital Chimú pudieron almacenar muchos objetos en su interior (el mayor tiene 27.09 m2 y 22.76 m3), es el palacio Uhle el que presente mayor capacidad como área de almacenamiento (1852.68 m2 y 1671.50 m3). Toda esta organización de recaudación estuvo organizada desde puntos de control denominados “audiencias” y su preponderancia dentro de los palacios estuvo asociada el acceso a los recursos durante la realización de las actividades políticas en la urbe, siendo posible reconocer las políticas administrativas que existió durante la construcción de los palacios Uhle y Bandelier.

Abstract:

A motorcyclist helmet is considered important safety equipment because it prevents or minimizes head and brain injuries, which are often fatal. Hence, in the 1960s and 1970s, most of the states in the United States enacted the universal helmet law (UHL) requiring all motorcyclists to wear helmets. Many researchers have examined the effect of the helmet law changes by using before-and-after studies and found that repealing the law had a negative effect on motorcyclists. In this study, the authors have attempted to explore the long-term impacts of repeal and reinstatement of the UHL by using 13 to 16 years of data. A before-and-after study with a comparison group and empirical Bayes methods was adopted to account for the passage of time and its effect on other factors such as exposure, maturation, trend, and regression-to-the-mean bias. A range of safety performance functions was developed on the basis of counties and parishes, and the expected fatal motorcycle crashes were calculated. The results showed that the UHL repeal still had significant effects on motorcycle fatal crash counts even 7 to 12 years after the repeal of the law. The crash modification factors showed that the UHL repeal increased the number of motorcycle fatal crashes by 15% to 41%, whereas reinstatement of the UHL decreased it by 21% to 27%. It is expected that the results from this study could be helpful for state policy makers to clearly understand the effects of the UHL on reducing motorcycle fatal crashes.

Abstract:

Purpose This study examined the effects of stimulus type and hearing status on speech recognition and listening effort in children with normal hearing (NH) and children with mild bilateral hearing loss (MBHL) or unilateral hearing loss (UHL). Method Children (5–12 years of age) with NH (Experiment 1) and children (8–12 years of age) with MBHL, UHL, or NH (Experiment 2) performed consonant identification and word and sentence recognition in background noise. Percentage correct performance and verbal response time (VRT) were assessed (onset time, total duration). Results In general, speech recognition improved as signal-to-noise ratio (SNR) increased both for children with NH and children with MBHL or UHL. The groups did not differ on measures of VRT. Onset times were longer for incorrect than for correct responses. For correct responses only, there was a general increase in VRT with decreasing SNR. Conclusions Findings indicate poorer sentence recognition in children with NH and MBHL or UHL as SNR decreases. VRT results suggest that greater effort was expended when processing stimuli that were incorrectly identified. Increasing VRT with decreasing SNR for correct responses also supports greater effort in poorer acoustic conditions. The absence of significant hearing status differences suggests that VRT was not differentially affected by MBHL, UHL, or NH for children in this study.

Abstract:

The Formative in the northern AndesThe northern Andean regions, encompassing northernmost Peru, all of Ecuador and the southern provinces of Colombia, remain archaeologically very poorly known. Although the past 30 years have witnessed an increasing number of archaeological projects in coastal zones, especially the Santa Elena Peninsula, work in the highlands outside of the greater Quito commute zone has lagged sadly behind. Southern Ecuador, in particular, has had little investigation since earlier this century when first Max Uhle, then Donald Collier, John Murra and, finally, Wendell Bennett, demonstrated the existence of ‘Formative’ cultures in Ecuador through their investigations at sites along the Tomebamba and Paute rivers of Azuay province and at Cerro Narrío, just to the north in the Cañar Valley (Uhle 1922; Collier & Murra 1943; Bennett 1946; FIGURE 1).

Abstract:

Abstract Background Hearing loss may occur in patients with posterior fossa low-grade glioma who undergo surgery. Methods We retrospectively reviewed 217 patients with posterior fossa low-grade glioma, including 115 for whom results of hearing tests performed after surgery and before chemotherapy or radiation therapy were available. We explored the association of UHL with age at diagnosis, sex, race, tumor location, extent of resection, posterior fossa syndrome, ventriculoperitoneal shunt placement, and histology. Results Of the 115 patients, 15 (13.0%: 11 male, 6 black, 8 white, 1 multiracial; median age 7 years [range, 1.3–17.2 years]) had profound UHL after surgery alone or before receiving ototoxic therapy. Median age at tumor diagnosis was 6.8 years (range, 0.7–14.1 years), and median age at surgery was 6.8 years (range, 0.7–14.1 years). Patients with UHL had pathology characteristic of pilocytic astrocytoma (n = 10), ganglioglioma (n = 4), or low-grade astrocytoma (n = 1). Of these 15 patients, 4 underwent biopsy, 1 underwent gross total resection, 1 underwent near-total resection, and 9 underwent subtotal resection. UHL was more frequent in black patients than in white patients (OR 7.3, P = .007) and less frequent in patients who underwent gross total resection or near-total resection than in those who underwent subtotal resection (OR 0.11, P = .02). Conclusions Children undergoing surgery for posterior fossa low-grade glioma are at risk for UHL, which may be related to race or extent of resection. These patients should receive postoperative audiologic testing, as earlier intervention may improve outcomes.

Abstract:

Objective: Patients with moderate-to-profound sensorineural hearing loss in 1 ear and normal hearing in the contralateral ear, known as unilateral hearing loss (UHL) or single-sided deafness (SSD), may experience improved quality of life with the use of a cochlear implant (CI) in the affected ear. Quality of life assessment before and after implantation may reveal changes to aspects of hearing beyond those explicitly evaluated with behavioral measures. Methods: The present report completed 2 experiments investigating quality of life outcomes in CI recipients with UHL. The first experiment assessed quality of life during the 1st year of device use with 3 questionnaires: the Speech, Spatial, and Qualities of Hearing Scale (SSQ), the Abbreviated Profile of Hearing Aid Benefit (APHAB), and the Tinnitus Handicap Inventory. Twenty subjects were evaluated preoperatively and 1, 3, 6, 9, and 12 months post-activation. Quality of life results were compared over the study period using traditional scoring methods and the SSQ pragmatic subscales. Subscales specific to localization and speech perception in noise were compared to behavioral measures at the preoperative and 12-month intervals. The 2nd experiment evaluated quality of life preoperatively and at the 12-month interval for CI recipients with UHL and CI recipients with bilateral hearing loss, including conventional CI users and those listening with electric-acoustic stimulation (EAS). The 3 cohorts differed in CI candidacy criteria, including the amount of residual hearing in the contralateral ear. Results: For subjects with moderate-to-profound UHL, receipt of a CI significantly improved quality of life, with benefits noted as early as 1 month after initial activation. The UHL cohort reported less perceived difficulty at the pre- and postoperative intervals than the conventional CI and EAS cohorts, which may be due to the presence of the normal-hearing ear. Each group experienced a significant benefit in quality of life on the APHAB with CI use. Conclusions: Cochlear implantation in cases of substantial UHL may offer significant improvements in quality of life. Quality of life measures revealed a reduction in perceived tinnitus severity and subjective improvements in speech perception in noise, spatial hearing, and listening effort. While self-report of difficulties were lower for the UHL cohort than the conventional CI and EAS cohorts, subjects in all 3 groups reported an improvement in quality of life with CI use.

Abstract:

Purpose Cochlear implantation may be a viable treatment option for patients with moderate-to-profound hearing loss in 1 ear and normal to near-normal hearing in the contralateral ear. There is a need for modified aural rehabilitation assessment and intervention tools for this unique patient population to support improvements with the cochlear implant (CI). The present report describes the development and implementation of the Assessment and Aural Rehabilitation Tool (AART) created for adult CI recipients with unilateral hearing loss (UHL). Conclusion The tool was used as an early assessment measure for CI in subjects with UHL and as a method to determine individualized auditory training plans. The AART was modified considering the initial abilities of this unique subject group. Ongoing studies are assessing the effectiveness of CI use in pediatric subjects with UHL and developing the pediatric version of the AART.

Abstract:

This review article addresses some of the complex issues surrounding antidepressant drug usage among elderly depressives. While primarily geared toward the psychiatrist in general practice, the article provides useful information for the nonpsychiatric physician who is frequently called upon to evaluate and treat affective disorders in the geriatric population. Since tricyclic antidepressants and lithium are the most commonly used psychotropic drugs in the treatment of depression, their side effects and adverse reactions are discussed specifically as these relate to the elderly. Suggestions are offered on how to improve safety and enhance compliance. Brief mention is made of the monoamine oxidase inhibitors and the second generation antidepressants. Dose ranges are recommended for use of these agents in geriatric patients. Finally, a section of the article reviews the most commonly encountered drug interactions between tricyclic and a variety of other psychotropic and nonpsychotropic drugs.

Abstract:

Objective Options for management of unilateral hearing loss (UHL) in children include conventional hearing aids, bone-conduction hearing devices, contralateral routing of signal (CROS) aids, and frequency-modulating (FM) systems. The objective of this study was to systematically review the current literature to characterize auditory outcomes of hearing rehabilitation options in UHL. Data Sources PubMed, EMBASE, Medline, CINAHL, and Cochrane Library were searched from inception to January 2016. Manual searches of bibliographies were also performed. Review Methods Studies analyzing auditory outcomes of hearing amplification in children with UHL were included. Outcome measures included functional and objective auditory results. Two independent reviewers evaluated each abstract and article. Results Of the 249 articles identified, 12 met inclusion criteria. Seven articles solely focused on outcomes with bone-conduction hearing devices. Outcomes favored improved pure-tone averages, speech recognition thresholds, and sound localization in implanted patients. Five studies focused on FM systems, conventional hearing aids, or CROS hearing aids. Limited data are available but suggest a trend toward improvement in speech perception with hearing aids. FM systems were shown to have the most benefit for speech recognition in noise. Studies evaluating CROS hearing aids demonstrated variable outcomes. Conclusions Data evaluating functional and objective auditory measures following hearing amplification in children with UHL are limited. Most studies do suggest improvement in speech perception, speech recognition in noise, and sound localization with a hearing rehabilitation device.

Abstract:

A partir de una tradición de estudios de los pueblos indígenas americanos que se remonta a Alexander von Humboldt y que en el Perú cuenta con personalidades como Johann Jakob von Tschudi y Ernst Middendorf, Max Uhle aparece en el horizonte de la historia de las ciencias como un notable continuador y un perspicaz innovador. Sus investigaciones de más de cuarenta años, de 1892 a 1933, particularmente en el ámbito andino, incluyendo Ecuador, Perú, Bolívia, el noroeste de Argentina y el centro-sur de Chile, estuvieron dedicadas a la lingüística y la etnografía, a la arqueología y a los procesos históricos de los pueblos prehispánicos. El artículo ofrece una visión de conjunto de la obra de Uhle, vinculando esos trabajos con la tradición germánica a la que pertenece, llama la intención sobre su propuesta interdisciplinaria y destaca la intencionalidad política que ese investigador atribuyó al quehacer en el campo de la historia prehispánica en el espacio sudamericano.

Abstract:

High neutrophil (PMN, Polymorphonuclear neutrophil) counts in the endometrium of cows affected by endometritis, suggests the involvement of oxidative stress (OS) among the causes of impaired fertility. Protein oxidation, in particular, advanced oxidation protein products (AOPP), are OS biomarkers linked to PMN activity. To test this hypothesis, the relationship between protein oxidation and uterus health was studied in thirty-eight dairy cows during the puerperium. The animals were found to be cycling, without any signs of disease and pharmacological treatments. PMN count was performed either through a cytobrush or a uterine horn lavage (UHL). Cows were classified into four groups, based on the uterine ultrasonographic characteristics and the PMN percentage in the uterine horns with a higher percentage of high neutrophil horn (HNH). They were classified as: Healthy (H); Subclinical Endometritis (SCE); Grade 1 Endometritis (EM1); and Grade 2 Endometritis (EM2). AOPP and carbonyls were measured in plasma and UHL. UHL samples underwent Western blot analysis to visualize the carbonyl and dityrosine formation. Plasma AOPP were higher (p < 0.05) in EM2. AOPP and carbonyl group concentrations were higher in the HNH samples (p < 0.05). Protein concentration in the UHL was higher in the EM2 (p < 0.05). Carbonyl and dityrosine formation was more intense in EM1 and EM2. Protein oxidation observed in the EM2 suggests the presence of an inflammatory status in the uterus which, if not adequately hindered, could result in low fertility.

Abstract:

Tropical forests can recover after anthropogenic disturbances of light to moderate intensity (Aide et al. 1995, 1996, 2000; Uhl 1987, Uhl et al. 1988); however, severe disturbances (e.g. compaction or loss of soil) often result in conditions that prevent forest recovery. These degraded sites are often dominated by grasses (Aide & Cavelier 1994, Cabin et al. 2002, Cavelier et al. 1998, Uhl et al. 1988) and ferns (Cohen et al. 1995, García et al. 1994, Slocum et al. 2000, Walker & Boneta 1995) that can impose barriers for tree regeneration and arrest the succession process. Important barriers for tree regeneration include: (1) competition with grasses and ferns for soil moisture, nutrients and light (Aide & Cavelier 1994, Guimarães-Vieira et al. 1994, Holl et al. 2000, Nepstad et al. 1996, Russell et al. 1998, Walker 1994, Zimmerman et al. 2000), and (2) dispersal limitation given that grasses and fernlands offer few resources that attract seed dispersers (Guevara & Laborde 1993, Holl et al. 2000, McDonnell & Stiles 1983, Slocum & Horvitz 2000, Zimmerman et al. 2000).

Abstract:

To obtain the genuine load spectra of the components of engineering vehicles, the influencing factors in the extrapolation of load spectra should be considered because these are of paramount importance. In the present paper, a multi-criteria decision-making method (MCDM) is proposed to determine the proper upcrossing of the high and low levels (UHLL) for extrapolation of the Rainflow matrix (RFM). First, the distribution characteristics of load amplitude extracted from observed RFMs are obtained. Subsequently, five criteria, namely, the statistic of mean, statistic of variance, coefficient of skewness, coefficient of kurtosis, and the experts’ preference, are selected to describe the fitting accuracy of the Weibull probability density function. Finally, the relationship between the load threshold and the level crossing function is determined after calculating their relative importance, and consequently, the proper UHLL is obtained. The usefulness and validity of the proposed method is illustrated by two typical load-time histories. Results show that the MCDM-based method can combine the subjective and objective factors and obtain an optimal load level.
