    Background: The etiology of sleep disruption in intensive care unit is poorly known and often ignored complication. It is caused by the environmental factors especially pain, noise, diagnostic testing and human interventions that cause sleep disruption. Light, medications and activities related to patient care interfere with patient's ability to have good sleep. There are multi-factorial environmental etiologies for disruption of sleep in ICU. Objective: The objective of this study was to evaluate the factors disturbing the sleep quality in intensive care unit (ICU) admitted patients. Methodology: A cross sectional study was designed involving 150 patients admitted in intensive care unit and high dependency unit of Gulab Devi Chest Hospital. The duration of study was from September 2015 to March 2016. The questionnaire was made and filled with the help of patients. The data was analyzed using SPSS version 16.00. Results: Mean age of patients was 50.46+10.96 with maximum age of 65 and minimum age of 30 years. There was 53.33% male patients and 46.67% females participating in this study. The sleep quality was significantly poor in ICU than at home. After analysis, 54.67% patients were with poor quality of sleep due to pain and 48.67% were due to noise of environmental stimuli. The other factors were alarms, light and loud talking. Conclusion: Current study shows that reduced sleep quality is a common problem in ICU with multi-factorial etiologies. Patient reported the poor sleep quality in ICU due to environmental issues that are potentially modifiable.

    Treatment of a System with Explicitly Broken Gauge Symmetries

    Full text link
    A system in which the free part of the action possesses a gauge symmetry that is not respected by the interacting part presents problems when quantized. We illustrate how the Dirac constraint formalism can be used to address this difficulty by considering an antisymmetric tensor field interacting with a spinor field.Comment: 10 pages, LaTeX2e, typos correcte

    Tulang ikan merupakan salah satu bentuk limbah dari pengolahan ikan. Tepung tulang ikan bandeng memiliki kandungan kalsium dan fosfor yang tinggi dan dapat menjadi sumber alternatif untuk pemenuhan kalsium dan fosfor dalam tubuh. Penelitian ini bertujuan untuk mengetahui tingkat penerimaan konsumen terhadap donat dengan penambahan tepung tulang ikan bandeng dan pengaruh suhu pemanggangan donat, serta menjadi sumber alternatif pemenuhan kalsium dan fosfor dalam tubuh. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) pola faktorial yang terdiri atas 2 (dua) faktor. Faktor yang pertama adalah penambahan tepung tulang ikan bandeng dalam adonan kue donat (T) dengan 3 taraf yaitu T1 = 5%, T2 = 7,5%, dan T3 = 10% dari berat tepung terigu. Faktor kedua adalah suhu pemanggangan (S) yang terdiri dari 2 taraf yaitu S1 = 170oC, dan S2 = 180oC. Setiap perlakuan diulang 3 (tiga) kali sehingga diperoleh 18 satuan percobaan. Randemen tepung tulang ikan bandeng yang diperoleh dari proses penepungan yaitu 57,1% dengan nilai kadar kalsium sebesar 5,24% dan fosfor 2,36%. Hasil penelitian menunjukkan bahwa donat panggang dengan penambahan tepung tulang ikan bandeng sebanyak 5% dan suhu pemanggangan 170oC lebih disukai dari semua perlakuan. Nilai terhadap kadar air yaitu sebesar 17,37%, kadar protein 40,43%, kadar abu 8,39%, kadar lemak 0,03%, kadar kalsium 0,31%, dan kadar fosfor 0,22%. Nilai rata-rata organoleptik terhadap warna yaitu 3,80 (suka), rasa 3,11 (netral), aroma 2,63 (netral), dan tekstur 3,29 (netral)

    Interference and Deployment Issues for Cognitive Radio Systems in Shadowing Environments

    In this paper we describe a model for calculating the aggregate interference encountered by primary receivers in the presence of randomly placed cognitive radios (CRs). We show that incorporating the impact of distance attenuation and lognormal fading on each constituent interferer in the aggregate, leads to a composite interference that cannot be satisfactorily modeled by a lognormal. Using the interference statistics we determine a number of key parameters needed for the deployment of CRs. Examples of these are the exclusion zone radius, needed to protect the primary receiver under different types of fading environments and acceptable interference levels, and the numbers of CRs that can be deployed. We further show that if the CRs have apriori knowledge of the radio environment map (REM), then a much larger number of CRs can be deployed especially in a high density environment. Given REM information, we also look at the CR numbers achieved by two different types of techniques to process the scheduling information.Comment: to be presented at IEEE ICC 2009.

    Background: Postoperative nausea and vomiting are common and distressing postsurgical symptoms. These symptoms are of particular concern in outpatient surgery because they may require additional direct resources, such as supplies and antiemetic drugs, and may delay discharge. The objective of this study was to measure the frequency of factors which can cause nausea and vomiting under general anaesthesia after chest surgery. Methodology: This descriptive case series evaluated frequency of predisposing factor of nausea and vomiting in patients of anaesthesia department of Gulab Devi Hospital Lahore. Questionnaire is made and patients were asked about their age, fever, previous surgery, NPO status, smoking history and hospital stay. This study included 140 patients with post-operative nausea and vomiting. Results: In this study, 140 patients were taken in which  65 (46.43%) were female and 75 (53.57%) were male. In 140 patient 134 (95.7%) were NPO and 6 (4.3%) were not  NPO, 25 (17.9%) were obese and 115 (82.1%) were not obese, 88 (62.9%) patients were suffering fever and 52 (37.1%) were not suffering fever, 80 (57.1%) were infected and 59 (42.1%) were not infected, 53 (37.9%) patients had previous surgery and 87 (62.1%) had no previous surgery, 94 (67.1%) patients had received nitrous oxide and 46 (32.9%) didn\u27t, 97 (69.3%) received volatile gases and 43 (30.7%) not received, 29 (20.7%) received ketamine and 111 (79.3%) not received, 87 (62.1%) received suxamethonium and 53 (37.9%) not received, 119 (85.0%) received propofol and 21 (15.0%) not received, 110 (78.6%) received naluphine and 28 (20.0%) not received. Out of 140 patients, there were 122 (87.1%) who were suffering from pain and 18 (12.9%) were not. 91 (65.0%) patients had gastric distention and 49 (35.0%) patients didn\u27t. Opioids were given to 34 (24.3%) patients and not given to 106 (75.7%) patient. Conclusion: It is concluded that the nausea and vomiting after surgey under genral anesthesia is due to patient related factors in which most frequent is NPO. Drug related factors include propofol and nalbupin administration. Post operative factors include pain. In whole study of 140 patients, the  most frequent is patient related factor (NPO) other than drug related factors and post-operative factors

    Summing Radiative Corrections to the Effective Potential

    Full text link
    When one uses the Coleman-Weinberg renormalization condition, the effective potential VV in the massless ϕ44\phi_4^4 theory with O(N) symmetry is completely determined by the renormalization group functions. It has been shown how the (p+1)(p+1) order renormalization group function determine the sum of all the N^{\mbox{\scriptsize p}}LL order contribution to VV to all orders in the loop expansion. We discuss here how, in addition to fixing the N^{\mbox{\scriptsize p}}LL contribution to VV, the (p+1)(p+1) order renormalization group functions also can be used to determine portions of the N^{\mbox{\scriptsize p+n}}LL contributions to VV. When these contributions are summed to all orders, the singularity structure of \mcv is altered. An alternate rearrangement of the contributions to VV in powers of lnϕ\ln \phi, when the extremum condition V(ϕ=v)=0V^\prime (\phi = v) = 0 is combined with the renormalization group equation, show that either v=0v = 0 or VV is independent of ϕ\phi. This conclusion is supported by showing the LL, \cdots, N4^4LL contributions to VV become progressively less dependent on ϕ\phi.Comment: 16 pages; added 2 figures and 2 tables; references revise
