description: We present a self-consistent study of the stellar populations and the ionized gas in a sample of 10 HII galaxies with, at least, four measured electron temperatures and a precise determination of ionic abundances following the "direct method". We fitted the spectral energy distribution of the galaxies using the program STARLIGHT in order to quantify the contribution of the underlying stellar population to EW(Hbeta), which amounts to about 10% for most of the objects. We then studied the Wolf-Rayet stellar populations detected in seven of the galaxies. The presence of these populations and the corrected EW(Hbeta) values indicate that the ionizing stellar populations were created following a continuous star formation episode of 10 Myr duration, hence WR stars may be present in all of objects even if they are not detected in some of them. The derived stellar features, the number of ionizing photons and the relative intensities of the strongest emission lines were used as input parameters to compute tailored models with the photoionization code CLOUDY. Our models are able to y reproduce their thermal and ionization structure as deduced from their collisionally excited emission lines and, hence, no abundance discrepancy factors are implied for this kind of objects. Only the electron temperature of S+ is overestimated by the models, pointing to the possible presence of outer shells of diffuse gas in these objects. This kind of geometrical effects can affect the determination of the equivalent effective temperature of the ionizing cluster using calibrators which depend on low-excitation emission lines.

title: The Effects of Cultural Diplomacy on Public Perception in Asia
Creators: name: Johnson, Joseph R.
Publisher: name: Utah State University

description: Many states use their cultures to promote a positive image of themselves abroad. Some scholars argue that this can provide states with international benefits. However, other scholars point to cases where a foreign state’s cultural influence has led to nationalist backlashes and negative public reactions. In this paper, I examine how two common types of cultural diplomacy programs can influence how states are perceived abroad.
I first look at the promotion of pop culture products, such as books, movies, and music. Using survey data from 12 Asian countries, I find that an increase in cultural product imports from Japan, South Korea, and China has a negative effect on how respondents view the cultural exporter. I then look at cultural centers, using China’s Confucius Institute program. I find that the presence of Confucius Institutes is associated with an increase in positive opinions of China. These results provide some empirical evidence that cultural products can be detrimental to a state’s international image. As a result, states interested in the international benefits of cultural diplomacy should be wary of promoting cultural products abroad. Additionally, while previous studies do not distinguish between the effects that different types of cultural diplomacy programs can have, these findings demonstrate that different cultural diplomacy strategies can have widely different effects on foreign public opinion.

Effective Hamiltonians in the Quantum Rabi Problem

description: We revisit the theoretical description of the ultrastrong light-matter interaction in terms of exactly solvable effective Hamiltonians. A perturbative approach based on polaronic and spin-dependent squeezing transformations provides an effective Hamiltonian for the quantum Rabi model up to the second order in the expansion parameter. The model consistently includes both rotating and counter-rotating terms, going therefore beyond the rotating wave approximation. Analytical and numerical results show that the proposed Hamiltonian performs better than the Bloch-Siegert model when calculating operator averages (e.g.\, the mean photon number and number of excitations). This improvement is due to a refined calculation of the dressed states within the present model. Regarding the frequency shift induced by the qubit-photon interaction, we find a different sign from the Bloch-Siegert value. This influences the eigenstates structure in a non-trivial way and ensures the correct calculation of the number of excitations associated to a given dressed state. As a consistency check, we show that the exactly solvable independent boson model is reproduced as a special limit case of the perturbative Hamiltonian.

THE VALUES OF ISLAMIC EDUCATION IN PERSIS ISLAMIC BOARDING SCHOOLS AND THEIR ROLE IN INDONESIA
Creators: name: Muhajir Abd. Rahman

Subjects: Persis, Islamic Education Values, Indonesia.

description: Abstract

Persis Islam/Persis or Islamic Association was a small group of Indonesian Muslim activists from 1923 to 1957 who provided many lessons about the values of Islamic education. The research approach in this article is qualitative. The research findings are that Persis Islamic boarding school education is different from the Islamic boarding school system in general in Indonesia. The Islamic boarding school system seeks to combine Islamic education with general education and needs to recognize the dichotomy between the two. The Persis Islamic Boarding School education system has an educational curriculum that applies to Persis education from childhood education to university. In Persis' view, the purpose of education is not to become a civil servant. Still, the first thing is to believe in Allah, not to associate partners with Allah or forbid committing shirk and maintaining morals. Another finding is that the main source of educational value at the Persis Islamic Boarding School is the Al-Qur'an and Hadith. From this source emanate three main values, namely aqidah, worship, and muamalah; of these three central values is the habit of forming morals al-karimah (character) with all its derivatives such as honesty, sincerity, trust, discipline, struggle, and so on. These values are inherited and shape the students' personalities to later live as Indonesian citizen.
title: Promoting Sociodramatic Play Between Children with Autism and Their Typically Developing Peers Using Activity Schedules

description: Young children with Autism Spectrum Disorder (ASD) demonstrate behavioral deficits and excesses that can adversely affect their play skills. Teaching children with ASD to use activity schedules with embedded scripts have led to increased appropriate game play with other children with autism and typically developing peers; however, there is sparse research on promoting more dynamic social play in children with ASD. The purpose of this study was to examine the effects of teaching the use of activity schedules with embedded scripts on the sociodramatic play of preschoolers with ASD with their typically developing peers. We also examined the extent to which we could remove scripts and schedule components and continue to observe appropriate sociodramatic play. Two participants with ASD quickly demonstrated high levels of sociodramatic play with their typically developing peers compared to baseline, and an additional participant with ASD demonstrated similar increases with procedural modifications. The participants also continued to show these increased levels after all scripts and nearly all components of the activity schedules were systematically removed, including during 1-and 2-week follow-up sessions. In addition, all participants engaged in additional unscheduled, yet contextually appropriate, sociodramatic play behaviors.

description: Trade Fairs, throughout their long history, have always interacted with their host cities on multiple levels. The significant contribution of trade fairs to the tourism development of their host cities was and still remains undisputed. The city of Thessaloniki has recorded a long and remarkable historical tradition in the organisation of trade fairs. This paper attempts to examine the concept of the ‘Honoured Country’ within the framework of the International Fair of Thessaloniki, historically, and to explore its multifaceted role. The central hypothesis of this paper concerns the exploration of the multi-aspect role of the ‘Honoured Country’ concept during TIF and the highlighting of its impact on the city’s tourism development. This exploration will take place both over time – through the study of the historical archives of TIF-HELEXPO – as well as through the case study of the 82nd TIF, during which China was be the ‘Honoured Country’.

description: We present an imaging study of the black hole binary candidate SDSS J1536+0441 (z=0.3893), based on deep, high resolution VzK images collected at the ESO/VLT. The images clearly show an asymmetric elongation, indicating the presence of a companion source at ~1" (~5 kpc projected distance) East from the quasar. The host galaxy of the quasar is marginally resolved. We find that the companion source is a luminous galaxy, the light profile of which suggests the presence of an unresolved, faint nucleus (either an obscured AGN or a compact stellar bulge). The study of the environment around the quasar indicates the occurrence of a significant over-density of galaxies with a redshift compatible with z~0.4. This suggests that it resides in a moderately rich cluster of galaxies.

description: I have carried out a search for Planet 9 in the IRAS data. At the distance range proposed for Planet 9, the signature would be a 60 micron unidentified IRAS point source with an associated nearby source from the IRAS Reject File of sources which received only a single hours-confirmed (HCON) detection. The confirmed source should be detected on the first two HCON passes, but not on the third, while the single HCON should be detected only on the third HCON. I have examined the unidentified sources in three IRAS 60micron catalogues: some can be identified with 2MASS galaxies, Galactic sources or as cirrus. The remaining unidentified sources have been examined with the IRSA Scanpi tool to check for the signature missing HCONs, and for association with IRAS Reject File single HCONs. No matches of interest survive. For a lower mass planet (< 5 earth masses) in the distance range 200-400 AU, we expect a pair or triplet of single HCONs with separations 2-35 arcmin. Several hundred candidate associations are found and have been examined with Scanpi. A single candidate for Planet 9 survives which satisfies the requirements for detected and non-detected HCON passes. A fitted orbit suggest a distance of 225+-15 AU and a mass of 3-5 earth masses. Dynamical simulations are needed to explore whether the candidate is consistent with existing planet ephemerides. If so, a search in an annulus of radius 2.5-4 deg centred on the 1983 position at visible and near infrared wavelengths would be worthwhile.

description: Depersonalisation/derealisation disorder (DPD) refers to frequent and persistent detachment from bodily self and disengagement from the outside world. As a dissociative disorder, DPD affects 1-2% of the population, but takes 7-12 years on average to be accurately diagnosed. In this systematic review, we comprehensively describe research targeting the neural correlates of core DPD symptoms, covering publications between 1992 and 2020 that have used electrophysiological techniques. The aim was to investigate the diagnostic potential of these relatively inexpensive and convenient neuroimaging tools. We review the EEG power spectrum, components of the event-related potential (ERP), as well as vestibular and heartbeat evoked potentials as likely electrophysiological biomarkers to study DPD symptoms. We argue that acute anxiety- or trauma-related impairments in the integration of interoceptive and exteroceptive signals play a key role in the formation of DPD symptoms, and that future research needs analysis methods that can take this integration into account. We suggest tools for prospective studies of electrophysiological DPD biomarkers, which are urgently needed to fully develop their diagnostic potential.

description: We have studied the electrical conductivity of nanoring-based, transparent conductive films, these being promising elements for flexible electronic devices. Both the wire resistance and the junction resistance were taken into account. We have calculated the dependency of the electrical conductivity on the number density of the rings. We have proposed a mean-field approach to estimate the dependency of the electrical conductivity on the main parameters. Comparison of direct computations of the electrical conductivity and the estimates provided by the mean-field approach evidenced the applicability of this approach for those cases where the wire resistance dominates over the junction resistance and where both resistances are of the same order. For these two cases, both the direct computations and the mean-field approach evidenced a linear dependence of the electrical conductivity of the films on the number density of the conductive rings. By contrast, the dependence of the electrical conductivity on the number density of the conductive rings is a quadratic when the junction resistance dominates over the wire resistance. In this case, the mean-field approach significantly overestimates the electrical conductivity, since the main assumptions underlying this approach are no longer fulfilled.

title: Attracting Secondary Students to STEM Using a Summer Engineering Camp
Creators: name: Mahmoud, Murad
Publisher: name: Utah State University

description: The purpose of this research was to study the benefits of having middle school students attend a summer camp focused on the fields of Science, Technology, Engineering and Mathematics (STEM). A lot of research funding is being used in such camps to help get more students into STEM fields as there is a lack of graduates in those fields. Therefore, it is important to understand the benefits and effectiveness of such camps.
Students, teachers and parents were involved in this research. Students and teachers attended a one-week engineering camp at Utah State University while parents were involved via a blog updated daily with a summary of the activities of the day, pictures, and quotes from the students.
The results show that those kinds of camps are effective at increasing students’ interest in STEM fields and in improving parents’ perceptions about those fields. Interestingly, students who started the camp with low interest in STEM fields gained a lot more from the camp than the other students. Similarly, female students also gained a lot more through the camp than male students. This leads us to believe that future camps should target students that stand to gain more from such camps.

description: X-ray monitoring observations were performed with the Swift observatory of the ultraluminous X-ray sources Holmberg IX X-1, NGC 5408 X-1, and NGC 4395 X-2 and also of the nuclear X-ray source in NGC 4395. Holmberg IX X-1 remains in the hard X-ray spectral state as its flux varies by a factor of 7 up to an (isotropic) luminosity of 2.8E40 erg/s. This behavior may suggest an unusually massive compact object. We find excess power at periods near 60 days and 28 days in the X-ray emission from Holmberg IX X-1. Additional monitoring is required to test the significance of these signals. NGC 5408 X-1 and NGC 4395 X-2 appear to remain in the soft spectral state found by Chandra and XMM with little variation in spectral hardness even as the luminosity changes by a factor of 9. We found an outburst from the nuclear source in NGC 4395 reaching an X-ray luminosity of 9E40 erg/s, several times higher than any previously reported.

description: Abstract

The era of bureaucratic reform in Indonesia has triggered significant changes in human resource management in the public sector. This study aims to examine the mediating role of organizational commitment in the relationship between leadership style and employee organizational citizenship behavior (OCB). OCB, which includes voluntary and extra-role behaviors, becomes essential to improve organizational effectiveness during this period of change.  This study uses a quantitative survey method with a simple random sampling technique of 153 employees in West Sulawesi Provincial government agencies who are undergoing a bureaucratic reform process. Data were collected through questionnaires and analyzed using SmartPls path analysis with result analysis using SmartPLS structural equation modeling. The results show that an effective leadership style has a positive and significant impact on employees' OCB, which in turn increases their OCB levels. In addition, organizational commitment proves to be a strong mediator in the relationship between leadership styles and OCB. These findings underscore the importance of leaders who can build strong organizational commitments to encourage positive behaviors outside of formal duties. The practical implications of this study include the need for leadership development that can inspire and strengthen organizational commitment to support the success of bureaucratic reform.
title: Catastrophic Wildfire Hazard Assessment in Pinyon-Juniper Woodlands Utilizing a Managerial Paradigm
Creators: name: Baldwin, Benjamin D.
Publisher: name: Utah State University
Year: 2003

description: The impetus for this research was the increasing threat of catastrophic wildfires resulting from the accumulation of fuels across the West. Guided by the priorities, goals, and guiding principles outlined by the national fire plan (NFP), the objective was to identify those areas within a pinyon-juniper woodland-dominated landscape with the highest hazard of catastrophic wildfire. The intent was to help managers prioritize proactive fuels management efforts outside of the wildland urban interface (WUI). Based on a management paradigm, constraints were placed on the data collection, analysis, and model development. A geographic information system (GIS) was used to create a hazard assessment at a landscape scale in Tintic Valley, Utah. Hazard categories were a classification of fuels based on crown cover of pinyon-juniper trees, utilizing remotely sensed data. The data set consisted of digital orthophoto quadrangle (DOQ) images from 1993. The methods were developed in three phases. Phase One resulted in a hazard assessment protocol. In Phase Two, data layers were created to further divide the hazard categories into more tractable management units. Phase Three, through the retrospective examination of recent wildfires, indicated the limitations and utility of the assessment technique. The protocol presented provides a relatively fast, inexpensive, and timely hazard classification technique for pinyon-juniper woodlands at a watershed level. It is intended to be used for coarse-scale assessments of fuel hazards for strategic planning purposes. While not appropriate for fire behavior predictions, this assessment can focus managerial efforts for additional tactical planning.

description: The ab-initio calculation of resonance lifetimes of metastable anions challenges modern quantum-chemical methods. The exact lifetime of the lowest-energy resonance is encoded into a complex "density" that can be obtained via complex-coordinate scaling. We illustrate this with one-electron examples and show how the lifetime can be extracted from the complex density in much the same way as the ground-state energy of bound systems is extracted from its ground-state density.

description: Bringing together considerations from three research trends (honest signals of collaboration, socio-semantic networks and homophily theory), we hypothesise that word use similarity and having similar social network positions are linked with the level of employees' digital interaction. To verify our hypothesis, we analyse the communication of close to 1600 employees, interacting on the intranet communication forum of a large company. We study their social dynamics and the 'honest signals' that, in past research, proved to be conducive to employees' engagement and collaboration. We find that word use similarity is the main driver of interaction, much more than other language characteristics or similarity in network position. Our results suggest carefully choosing the language according to the target audience and have practical implications for both company managers and online community administrators. Understanding how to better use language could, for example, support the development of knowledge sharing practices or internal communication campaigns.

description: Background: Brain cooling (BC) represents the elective treatment in asphyxiated newborns. Amplitude Integrated Electroencephalography (aEEG) and Near Infrared Spectroscopy (NIRS) monitoring may help to evaluate changes in cerebral electrical activity and cerebral hemodynamics during hypothermia.
Objectives: To evaluate the prognostic value of aEEG time course and NIRS data in asphyxiated cooled infants.
Methods: 12 term neonates admitted to our NICU with moderate-severe Hypoxic-Ischemic Encephalopathy (HIE) underwent selective BC. aEEG and NIRS monitoring were started as soon as possible and maintained during the whole hypothermic treatment. Follow-up was scheduled at regular intervals; adverse outcome was defined as death, cerebral palsy (CP) or global quotient < 88.7 at  Griffiths’ Scale.
Results: 2/12 infants died, 2 developed CP, 1 was normal at 6 months of age and then lost at follow-up and 7 showed a normal outcome at least at 1 year of age. The aEEG background pattern at 24 hours of life was abnormal in 10 newborns; only 4 of them developed an adverse outcome, whereas the 2 infants with a normal aEEG developed normally. In infants with adverse outcome NIRS showed a higher Tissue Oxygenation Index (TOI) than those with normal outcome (80.0±10.5% vs 66.9±7.0%, p=0.057; 79.7±9.4% vs 67.1±7.9%, p=0.034; 80.2±8.8% vs 71.6±5.9%, p=0.069 at 6, 12 and 24 hours of life, respectively).
Conclusions: The aEEG background pattern at 24 hours of life loses its positive predictive value after BC implementation; TOI could be useful to predict early on infants that may benefit from other innovative therapies.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Visitors, residents and business organizations who are associated directly or indirectly with a market destination need to develop dynamic relations through co-operation. The paper argues for the necessity of public and private collaboration, an issue that needs to be taken into consideration when networks are created for tourism marketing. National tourism organisations can have a significant role to play in these networks. To this end, the role of social media and information technology is of significance for destination marketing. Incorporation of information and communication technologies and the adoption of c-commerce in a marketing tourism destination strategy may strengthen networks and alliances between the public-private sector for the implementation of a successful tourism development.

description: The Beartooth Nature Center (BNC) is Montana’s premier wildlife education refuge. Home to over seventy wild animals unable to be returned to their natural environments after accidents or abandonment, the BNC houses mountain lions, bears, moose, bobcats, and a variety of large birds. Located in Red lodge, Montana, the northern gateway to the world- renowned Yellowstone National Park, the BNC is in a unique position to create greater awareness of important ecological and wilderness sustainability issues for. Primarily funded through donations from tourists and local residents, effective branding and marketing are crucial for its survival. This article presents a 2011 student-driven brand development and marketing campaign designed to create greater visibility and name recognition for the BNC. Using contemporary theories which emphasize the importance of including all stakeholders in the branding process, students created a brand-positioning television and targeted collateral campaign. As a result of this campaign, attendance at the BNC doubled the following summer. This case study confirms that bringing multiple stakeholders into the branding process is a highly effective way to create a powerful message for eco-tourist destinations.

description: Abstract

Improvement of gelatin fibrous scaffold by electrospinning technique allows the preparation of ultrafine fibers with diameters ranging from micron to nanoscale fibrous materials. The electrospinning is a novel and efficient fabrication process that produced electrospun fibers through the action of an external electric field to create an electrically charged jet of polymer solution and it can able to be used as a wound closure material or tissue caused by an accident or by diseases etc. Include the development of characteristic to optimize for all applications and reduce the cost of the raw materials and develop to be used in a variety of applications. This research selected gelatin blended with polycaprolactone cellulose and carboxymethyl fabricated by using electrospinning technique for nanofibrous scaffold. We used design of experiment with voltage and feed rate for the ratios of gelatin/polycaprolactone were 100/0/0, 90/5/5, 80/15/5, 70/25/5 and 60/35/5, respectively. Gelatin and mixture was used to produce nanofiber scaffold in order to analyze fiber’s physical characteristic. The gelatin solution made from dissolving gelatin in water which serves as solvent for the solution because water is a great solvent for gelatin. However, the solution used in fiber production with electrospinning, this research used organic solvent, 2,2,2-trifluoroethanol, which is also a good solvent for gelatin PCL and CMC was dissolved in water instead hence produces good raw material for fiber production using electrospinning. To characterize the scaffolds, we analyzed the physical properties by investigating the morphology and measuring the fibers size using Scanning Electron Microscope revealed that when PCL increased from 0 to 35 percent CMC set at 0 to 5 percent, fiber’s size was decreased from 1.2 nm to 7.1 nm. Swelling ratio mixture of G100 ratio had swelling ratio of 11.74%. When adding more PCL, there will be more fiber as well, so the % can be remembered.
title: Using Geographic Information Systems and Remote Sensing to Analyze Fire Likelihood Areas at the Regional Scale in the Western United States

description: Geographic Information Systems (GIS) are increasingly used to examine fire activity. This study uses GIS to determine fire likelihood probabilities at an intermediate scale ( I-kilometer) on a daily basis given readily available data. Layers used for the analysis included slope, aspect, elevation, fuel type, proximity to existing fires, maximum temperature, minimum temperature, relative humidity, average vapor pressure deficit, precipitation, 1-hour fuel moisture, and 10-hour fuel moisture.
There were three objectives of this study: 1. Establish a correlation between burn perimeters and readily available topographic and environmental data, and map the spatial distribution of these as fire likelihood areas; 2. Compare each day's fire likelihood areas to fire perimeters from the next day to determine to what extent areas deemed to be high fire likelihood on a given day could be used to identify likelihood areas for the subsequent day; 3. Create a generalized model using the fewest and most frequent significant variables and test this model as a general predictive tool for fire likelihood over a given season.
Redundant variables and variables determined not to be significant at this scale were removed from the model. Variables that best explained the fire activity were identified and used to spatially map fire likelihood for any given day. By comparing subsequent days fire activity to the previous days fire likelihood areas, it was determined that the previous fire likelihood areas can be used as an indication for the subsequent day' s fire likelihood areas with a reasonable level of accuracy.
Although factors changed from day to day, the most significant variables tended to be slope, elevation, fuel type, and 1-hour fuel moisture. These variables were incorporated into a generalized model which, when mapped spatially, provided a method to compare increasing or decreasing levels of fire likelihood on a temporal scale. The results were coarser, but still indicated that a generalized model could be used to identify the next day' s fire likelihood areas given the previous days spatial plots. When compared to new fire starts, fires occurred in areas of moderate fire likelihood probabilities and very few occurred in areas of low probability.

description: We present the results of our study of the relationship between FR0 radio galaxies and GPS sources. Quasi-simultaneous radio spectra of 34 FR0s were obtained at 2.25-22.3 GHz with the radio telescope RATAN-600 in 2020-2021 during 2-6 epochs. Most FR0s have flat radio spectra, but we found many spectra with a peaked shape. Due to this fact and the compact nature of FR0s, we suggest their possible relationship with CSS/GPS radio sources. We analyzed broadband radio spectra of the 34 FR0s using the RATAN-600 measurements and available literature data. There are 14 FR0 objects which can be CSS/GPS radio source candidates. Most FR0s have broader radio spectra than those of genuine GPS sources, with FWHM > 2 like in blazars. Most spectral indices at the frequencies below and above the peak do not correspond to the values typical of canonical GPS sources. We classified 3 FR0s as low-power GPS sources according to the canonical criteria. The key issue is the variability properties of FR0s. Some FR0s demonstrate a variability level of up to 25 % on a time scale of one year according to the RATAN-600 measurements. The flare phenomena in FR0 objects can imply a relationship between them and blazars.

title: Energetic Requirements for Bacterial Protein Export
Creators: name: Corbett, John Andrew

description: Bacterial protein export involves the translocation of precursor proteins across the inner cytoplasmic membrane. Over 100 proteins are exported from Escherichia coli. This study showed that energy in the form of ATP and membrane gradient energy is essential for the export of leucine specific binding protein and (3-lactamase precursors. Ionophores or combinations of ionophores (SF6847, valinomycin/nigericin and valinomycin/monensin) which dissipate protonmotive force inhibit protein export. Valinomycin alone also inhibits export, but not as well as reagents which dissipate protonmotive force. Nigericin or monensin alone slightly stimulate protein export. These results suggest that the transmembrane electrical potential ( DY) is the component of membrane gradient energy necessary for precursor protein export.
ATP is necessary for the export of precursors. In the absence of ATP, in vitro export of leucine specific binding protein and B-lactamase precursors is not observed. An upper limit of l0μM was determined for the effective Km for ATP during in vitro protein export. It was also shown that ATP is consumed during the export process. The SecA protein was shown to contain an ATPase activity that is stimulated by the presence of inverted membranes and purified LSBP precursors.
Vanadate and diethylstilbestrol, inhibitors of ATPases, inhibit in vitro protein export. Vanadate also inhibits SecA ATPase activity which depends on membranes and precursors. Vanadate is a specific inhibitor of P-type ion translocating ATPases. This study showed primary sequence homology between part of the SecA protein and the phosphorylation sequence of P-type ATPases. Sequence homology, vanadate inhibition of SecA ATPase activity, and vanadate inhibition of in vitro protein export suggest that SecA may function by a mechanism similar to the E1E2 mechanism found in P-type ATPases.
Phosphorylation of two proteins with apparent sizes of 62 and 37 kDa is observed to occur in an export-associated fashion. This phosphorylation is dependent on membranes and precursors, is sensitive to hydroxylamine, and is sensitive to inhibitors of protein export, including valinomycin/nigericin and vanadate. Furthermore, phosphorylation of the 62 kDa protein is dependent on the presence of SecA. The phosphate linkage appears to be an acyl phosphate based on hydroxylamine sensitivity and reduction of the acyl phosphate linkage by NaCNBH3. Both proteins appear to be peripherally associated with the cytoplasmic face of the inner membrane, which is also consistent with a possible role in the bacterial protein export process.

description: The 1994 Beaver Mountain fire ignited the canopies of subalpine fir, Abies lasiocarpa, and spread ground fire into adjacent Douglas-fir forests, Pseudotsuga menziesii var. glauca. Despite shorter flight seasons due to lower annual temperatures and persistent snow, the Douglas-fir bark beetle, Dendroctonus pseudotsugae Hopkins, attacked a range of moderately fire-injured host conifers. Logistic regression models illustrated that in 1995 associated bark beetles selected large diameter Douglas-fir with 60-80% bole char, 60-80% crown volume scorch, and 50-70% probability of mortality due to fire. In 1996 beetle preference shifted to smaller diameter trees with lighter fire injury. Tree size was less significant for predicted attack in 1996 because most large fire-damaged conifers were colonized by beetles in 1995. Beetle populations did not reach outbreak proportions outside the fire boundary, but 53 green trees were also infested in 1997 along the burn perimeter.
Log linear tests conducted to quantify beetle emergence supported conclusions that beetles were not only attracted to mature, moderately fire-weakened conifers, but also produced greater brood numbers with up to 60-80 emergence holes/ 1800 cm2. Fire-defoliated trees provided bark beetles with sufficient phloem and limited resistance, allowing beetles to aggregate on areas of viable stem tissue regardless of overall bole char extent.
