Effect of thickness on optical properties of thermally evaporated SnS films

Abstract The effect of film thickness on the structure and optical properties of thermally evaporated SnS film has been studied. SnS films with different thicknesses in the range 152–585 nm were deposited onto clean glass substrates at room temperature. X-ray diffraction study revealed that SnS films of thickness ≥ 283 nm are crystalline, whereas films of lower thickness exhibit poor crystalline with more amorphous background. The crystalline nature of the lower film thickness has been confirmed using transmission electron microscope and the corresponding electron diffraction pattern. The thicker film samples showed nearly stoichiometric chemical composition; however, thinner samples are deficient in S and rich in Sn. The optical property of the deposited films has been investigated in the wavelength range 350–2500 nm. The refractive index increases notably with increasing film thickness. The refractive index for the investigated film thicknesses are adequately described by the effective-single-oscillator model. The static refractive index and the static dielectric constant have been calculated. Analysis of the optical absorption coefficient revealed the presence of direct optical transition and the corresponding band gap values were found to decrease as the film thickness increases.
Implementation of PV cell based standalone solar power system employing incremental conductance MPPT algorithm

The paper presented here proposes a Photovoltaic (PV) System consists of PV panel, Maximum Power Point tracker (MPPT) & DC-DC boost converter targeted for DC loads of a Stand-Alone Photovoltaic application. A circuit based simulation of Photovoltaic (PV) panel is proposed in order to analyse & estimate the electrical behaviour of the panel with respective change in environmental conditions like irradiation & temperature. The Photovoltaic (PV) panel characteristic which is achieved from Shockley diode equation is non linear in nature. Thus Maximum Power Point tracker is designed with the help of a new circuit based simulation of Incremental Conductance algorithm to extract maximum power from the panel. A DC-DC boost converter is designed to get constant DC voltage output from changing DC panel voltage and hence duty cycle of the converter is calculated accordingly. The proposed system is designed using MATLAB/Simulink and the results have been found to be satisfactory.
Cerebral venous thrombosis: a retrospective multicentre study of 48 patients

The objective was to describe the clinical features and management of cerebral venous thrombosis (CVT) in non-selected centres. An observational study in 11 neurological departments in NW Italy was carried out from 1995 through 1999 on 38 female and 10 male patients. Mean age: 44.8 years, SD=14.3. Onset: acute in 21 patients (44%), subacute in 17 (35%) and chronic in 10 (21%). Most frequent onset: with focal deficits and/or seizures, followed by impaired consciousness or confusion, isolated headache, isolated intracranial hypertension and cavernous syndrome. No risk factor was found in 8 patients (17%). The superior sagittal sinus was involved in 27 patients (56%) and the transverse sinus in 29 (60%). Anticoagulants were used in 45 patients (94%). Rankin Scale score at discharge: 0 (27 patients), 1 (four), 2 (five), 3 (five), 4 (none), 5 (one) and six were dead. Thirteen patients had deep CVT: age, risk factors, neurological signs and outcome differed from cortical CVT (35 patients), although not significantly. Clinical features, risk factors and outcome of CVT patients from non-selected centres are similar to those from specialised centres.
Genetic variants associated with sleep disorders

OBJECTIVE
The diagnostic boundaries of sleep disorders are under considerable debate. The main sleep disorders are partly heritable; therefore, defining heritable pathophysiologic mechanisms could delineate diagnoses and suggest treatment. We collected clinical data and DNA from consenting patients scheduled to undergo clinical polysomnograms, to expand our understanding of the polymorphisms associated with the phenotypes of particular sleep disorders.


METHODS
Patients at least 21 years of age were recruited to contribute research questionnaires, and to provide access to their medical records, saliva for deoxyribonucleic acid (DNA), and polysomnographic data. From these complex data, 38 partly overlapping phenotypes were derived indicating complaints, subjective and objective sleep timing, and polysomnographic disturbances. A custom chip was used to genotype 768 single-nucleotide polymorphisms (SNPs). Additional assays derived ancestry-informative markers (eg, 751 participants of European ancestry). Linear regressions controlling for age, gender, and ancestry were used to assess the associations of each phenotype with each of the SNPs, highlighting those with Bonferroni-corrected significance.


RESULTS
In peroxisome proliferator-activated receptor gamma, coactivator 1 beta (PPARGC1B), rs6888451 was associated with several markers of obstructive sleep apnea. In aryl hydrocarbon receptor nuclear translocator-like (ARNTL), rs10766071 was associated with decreased polysomnographic sleep duration. The association of rs3923809 in BTBD9 with periodic limb movements in sleep was confirmed. SNPs in casein kinase 1 delta (CSNK1D rs11552085), cryptochrome 1 (CRY1 rs4964515), and retinoic acid receptor-related orphan receptor A (RORA rs11071547) were less persuasively associated with sleep latency and time of falling asleep.


CONCLUSIONS
SNPs associated with several sleep phenotypes were suggested, but due to risks of false discovery, independent replications are needed before the importance of these associations can be assessed, followed by investigation of molecular mechanisms.
Factor price uncertainty, technology choice and investment delay

Abstract This paper develops a theory of putty-clay investment under factor price uncertainty using a Brownian motion framework. Ex ante the firm faces a choice of technologies that differ by their relative factor intensities, but ex post technologies are Leontief. The presence of competing technologies and factor price uncertainty can cause delay of profitable investments for a monopolist firm facing a one-time investment decision. Furthermore, uncertainty can cause an existing firm to wait for more extreme operating cost differentials before switching technologies. These delays in investment are present even without considering the effect of uncertainty on the firm's choice of scale.
The isostatic state of the southern Urals crust

Abstract The Uralide orogen, in Central Russia, is the focus of intense geoscientific investigations during recent years. The international research is motivated by some unusual lithospheric features compared with other collisional belts including the preservation of (a) a collisional architecture with an orogenic root and a crustal thickness of 55–58 km, and (b) large volumes of very low-grade and non-metamorphic oceanic crust and island arc rocks in the upper crust of a low–relief mountain belt. The latter cause anomalous gravity highs along the thickened crust and the isostatic equilibrium inside the Uralides lithosphere as well as the overthrust high-metamorphic rocks. The integrated URSEIS '95 seismic experiment provides fundamentally new data revealing the lithospheric architecture of an intact Paleozoic collisional orogen that allows the construction of density models. In the Urals' lithosphere different velocity structures resolved by wide-angle seismic experiments along both the URSEIS '95- and the Troitsk profile. They can be used to constrain lithospheric density models: a first model consists of a deep subducted continental lower crust which has been highly eclogitized at depths of 60–90 km to a density of 3550 kg/m3. The second model shows a slightly eclogitized lower crust underlying the Uralide orogen with a crustal thickness of 60 km. The eclogitized lower crust causes a too-small impedance contrast to the lithospheric mantle resulting in a lack of reflectors in the area of the largest crustal thickness. Both models fit the measured gravity field. Analyzing the isostatic state of the southern Urals' lithosphere, both density models are in isostatic equilibrium.
Moon lander [Book Review]

Schmidt offers a provocative critique of how scientists, engineers, and other professionals are groomed to fulfill a specific function in society—that of maintaining the status quo—and, in the process, end up sidelining their own goals and ideals. The book is both well researched and highly readable. Some readers may disagree with its conclusions, but everyone will recognize its descriptions of the often wrenching choices that today’s professionals must make. JK
The needs of patients with advanced, incurable cancer

Background:Limited research has investigated the specific needs of patients with advanced incurable cancer. The aim of this study was to describe the prevalence of perceived needs among this population.Methods:Medical specialists from two regions in New South Wales, Australia, identified patients with advanced, incurable cancer, who were estimated to have a life expectancy of <2 years and were not receiving formal palliative care. Of the 418 eligible patients, 246 (59%) consented to participate. Consenting patients completed the Needs Assessment for Advanced Cancer Patients questionnaire, which has demonstrable validity and reliability. Patients' perceived needs were assessed across the seven domains of the questionnaire: psychological, daily living, medical communication and information, symptom related, social, spiritual and financial needs.Results:Patients identified the greatest areas of need in relation to psychological and medical communication/information domains. Patients' specific needs were highest in dealing with a lack of energy and tiredness, coping with fears about the cancer spreading, and coping with frustration at not being able to do the things they used to do.Conclusion:This study indicates that patients with advanced, incurable cancer have high levels of unmet needs, especially in relation to the areas of psychological and medical communication/information needs. The data have the potential to guide the development of interventions aimed at meeting the current unmet needs of patients with advanced, incurable cancer.
Performance Evaluation of a Spectrum-Sensing Technique for Cognitive Radio Applications in B-VHF Communication Systems

This paper deals with a cognitive radio approach based on a noncooperative spectrum sensing technique for applications in a very-high-frequency (VHF) aeronautical communications system to detect idle VHF channels and allocate them to an additional overlay system or secondary users. In particular, the focus here is on a spectrum sensing technique belonging to the class of energy detectors based on the Welch windowed periodogram. The performance of the proposed detector is presented in terms of the missed detection probability of the primary user under different application conditions. The obtained results and resulting implementation complexity highlight better behavior of the proposed detector with respect to alternative schemes previously proposed in the literature on this subject.
Addition of salmeterol versus doubling the dose of fluticasone propionate in patients with mild to moderate asthma.

BACKGROUND
The objective of this multicentre, randomised, double blind, parallel group study was to compare the efficacy and safety of the addition of salmeterol with that of doubling the dose of fluticasone propionate in asthmatic patients not controlled by a low or intermediate dose of inhaled corticosteroids.


METHODS
After a four week run in period of treatment with fluticasone propionate (100 micrograms twice daily if pre-trial dose was 400-600 micrograms inhaled corticosteroids or 250 micrograms twice daily if pre-trial dose was 800-1200 micrograms inhaled corticosteroids), 274 patients were randomised to treatment for 12 weeks with either salmeterol 50 micrograms twice daily plus the run in dose of fluticasone propionate or twice the run in dose of fluticasone propionate (200 or 500 micrograms twice daily). Outcome measures were daily records of peak expiratory flow (PEF), symptom scores, and clinic lung function.


RESULTS
The improvements in both the morning and evening PEF were better in the salmeterol than in the fluticasone propionate group, the mean increase in morning PEF being 19 l/min higher (95% CI 11.0 to 26.1) and in evening PEF being 16 l/min (95% CI 18.4 to 24.0) higher in the salmeterol group. The increase in forced expiratory volume in one second (FEV1) was 0.09 1 greater in the salmeterol group than in the fluticasone propionate group after four weeks of treatment (95% CI 0.01 to 0.18), but not after 12 weeks. Both regimens showed an increase in symptom free days and a reduction in the need for rescue salbutamol both during the day and the night, but these improvements were greater in the salmeterol group. There were no significant differences between the groups in adverse effects or in the number of rescue course of oral corticosteroids.


CONCLUSIONS
In this group of patients still symptomatic despite 100 or 250 micrograms fluticasone propionate twice daily, the addition of salmetterol caused a greater improvement in lung function and symptom control than doubling the dose of fluticasone propionate.
Model Learning and Real-Time Tracking Using Multi-Resolution Surfel Maps

For interaction with its environment, a robot is required to learn models of objects and to perceive these models in the livestreams from its sensors. In this paper, we propose a novel approach to model learning and real-time tracking. We extract multi-resolution 3D shape and texture representations from RGB-D images at high frame-rates. An efficient variant of the iterative closest points algorithm allows for registering maps in real-time on a CPU. Our approach learns full-view models of objects in a probabilistic optimization framework in which we find the best alignment between multiple views. Finally, we track the pose of the camera with respect to the learned model by registering the current sensor view to the model. We evaluate our approach on RGB-D benchmarks and demonstrate its accuracy, efficiency, and robustness in model learning and tracking. We also report on the successful public demonstration of our approach in a mobile manipulation task.
Why is pain still not being assessed adequately? Results of a pain prevalence study in a university hospital in Sweden.

AIM
The aim of this study was to investigate the prevalence of pain and pain assessment among inpatients in a university hospital.


BACKGROUND
Pain management could be considered an indicator of quality of care. Few studies report on prevalence measures including all inpatients.


DESIGN
Quantitative and explorative.


METHOD
Survey.


RESULTS
Of the inpatients at the hospital who answered the survey, 494 (65%) reported having experienced pain during the preceding 24 hours. Of the patients who reported having experienced pain during the preceding 24 hours, 81% rated their pain >3 and 42.1% rated their pain >7. Of the patients who reported having experienced pain during the preceding 24 hours, 38.7% had been asked to self-assess their pain using a Numeric Rating Scale (NRS); 29.6% of the patients were completely satisfied, and 11.5% were not at all satisfied with their participation in pain management.


CONCLUSIONS
The result showed that too many patients are still suffering from pain and that the NRS is not used to the extent it should be. Efforts to overcome under-implementation of pain assessment are required, particularly on wards where pain is not obvious, e.g., wards that do not deal with surgery patients. Work to improve pain management must be carried out through collaboration across professional groups.


RELEVANCE TO CLINICAL PRACTICE
Using a pain assessment tool such as the NRS could help patients express their pain and improve communication between nurses and patients in relation to pain as well as allow patients to participate in their own care. Carrying out prevalence pain measures similar to those used here could be helpful in performing quality improvement work in the area of pain management.
Craving of prescription opioids in patients with chronic pain: a longitudinal outcomes trial.

UNLABELLED
Little is known about whether patients with chronic pain treated with opioids experience craving for their medications, whether contextual cues may influence craving, or if there is a relationship between craving and medication compliance. We hypothesized that craving for prescription opioids would be significantly correlated with the urge for more medication, preoccupation with the next dose, and current mood symptoms. We studied craving in 62 patients with chronic pain who were at low or high risk for opioid misuse, while they were enrolled in an RCT to improve prescription opioid medication compliance. Using electronic diaries, patients completed ratings of craving at monthly clinic visits and daily during a 14-day take-home period. Both groups consistently endorsed craving, whose levels were highly correlated (P < .001) with urge, preoccupation, and mood. The intervention to improve opioid compliance in the high-risk group was significantly associated with a rate of decrease in craving over time in comparison to a high-risk control group (P < .05). These findings indicate that craving is a potentially important psychological construct in pain patients prescribed opioids, regardless of their level of risk to misuse opioids. Targeting craving may be an important intervention to decrease misuse and improve prescription opioid compliance.


PERSPECTIVE
Patients with noncancer pain can crave their prescription opioids, regardless of their risk for opioid misuse. We found craving to be highly correlated with the urge to take more medication, fluctuations in mood, and preoccupation with the next dose, and to diminish with a behavioral intervention to improve opioid compliance.
The Sensorimotor System, Part II: The Role of Proprioception in Motor Control and Functional Joint Stability.

OBJECTIVE
To discuss the role of proprioception in motor control and in activation of the dynamic restraints for functional joint stability.


DATA SOURCES
Information was drawn from an extensive MEDLINE search of the scientific literature conducted in the areas of proprioception, motor control, neuromuscular control, and mechanisms of functional joint stability for the years 1970-1999.


DATA SYNTHESIS
Proprioception is conveyed to all levels of the central nervous system. It serves fundamental roles for optimal motor control and sensorimotor control over the dynamic restraints.


CONCLUSIONS/APPLICATIONS
Although controversy remains over the precise contributions of specific mechanoreceptors, proprioception as a whole is an essential component to controlling activation of the dynamic restraints and motor control. Enhanced muscle stiffness, of which muscle spindles are a crucial element, is argued to be an important characteristic for dynamic joint stability. Articular mechanoreceptors are attributed instrumental influence over gamma motor neuron activation, and therefore, serve to indirectly influence muscle stiffness. In addition, articular mechanoreceptors appear to influence higher motor center control over the dynamic restraints. Further research conducted in these areas will continue to assist in providing a scientific basis to the selection and development of clinical procedures.
Knowledge, Attitude and Practices of Mothers Regarding Infant Feeding Practices -

Background: Present study was conducted to assess the knowledge, attitude and practices of mothers towards infant feeding practices. Materials and methods: The mothers of infants, coming to a tertiary care centre, Ahmedabad, on outpatient basis were interviewed using a pre-designed questionnaire. Total 150 mothers were interviewed. Results: Out of the total, 18% mothers were illiterate.58.67% mothers have been counselled by doctor about feeding. Regarding breast feeding, 96% knew about exclusive breast feeding up to 6months. 90.67% think that colostrum is good for baby.34.67% mothers have given pre-lacteal feeds, tea and jaggery was most common.84.67% mothers knew that they should take extra food during lactation. Father (36%) most commonly help in feeding while 31.33% don’t get any domestic help.78.67% women consult doctor for feeding problems. Most common reason of stopping breast feeding was inadequate milk secretion(54.67%).18% think that feeding should be stopped during illness. 75.33% women were completely satisfied with their feeding practices. Conclusion-Mothers had good knowledge about infant feeding practices. Inspite of good knowledge there are lacunae in the practices of mothers due to social and economic reasons. Level of education has positive impact on infant feeding practices. Counselling by doctors had a better impact on the attitude and practices of mothers. Keywords-Infant feeding, breastfeeding, attitude and practice
Telecare for patients with type 1 diabetes and inadequate glycemic control: a randomized controlled trial and meta-analysis.

OBJECTIVE
To determine the efficacy of telecare (modem transmission of glucometer data and clinician feedback) to support intensive insulin therapy in patients with type 1 diabetes and inadequate glycemic control.


RESEARCH DESIGN AND METHODS
Thirty-one patients with type 1 diabetes on intensive insulin therapy and with HbA1c >7.8% were randomized to telecare (glucometer transmission with feedback) or control (glucometer transmission without feedback) for 6 months. The primary end point was 6-month HbA1c. To place our findings in context, we pooled HbA1c change from baseline reported in randomized trials of telecare identified in a systematic review of the literature.


RESULTS
Compared with the control group, telecare patients had a significantly lower 6-month HbA1c (8.2 vs. 7.8%, P = 0.03, after accounting for HbA1c at baseline) and a nonsignificant fourfold greater chance of achieving 6-month HbA1c < or =7% (29 vs. 7%; risk difference 21.9%, 95% CI -4.7 to 50.5). Nurses spent 50 more min/patient giving feedback on the phone with telecare patients than with control patients. Meta-analysis of seven randomized trials of adult patients with type 1 diabetes found a 0.4% difference (95% CI 0-0.8) in HbA1c mean change from baseline between the telecare and control groups.


CONCLUSIONS
Telecare is associated with small effects on glycemic control in patients with type 1 diabetes on intensive insulin therapy but with inadequate glycemic control.
