Kabupaten Murung Raya adalah salah satu kabupaten di Provinsi Kalimantan Tengah yang berada di pedalaman pulau kalimantan dan terletak di daerah khatulistiwa dengan ibukota Kabupaten di Kota Puruk Cahu. Sungai barito hulu merupakan induk dari be-berapa anak sungai yang ada di wilayah kabupaten murung raya yaitu : Sungai Laung, Sungai Babuat, Sungai Joloi, Sungai Busang. Debit Sungai Barito Hulu pada saat ini di-pergunakan untuk memenuhi berbagai macam sektor kebutuhan air disekitar Daerah Aliran Sungai (DAS) Barito Hulu yaitu di Puruk Cahu Kabupaten Murung Raya. Ketersediaan air dihitung dengan Metode Debit Andalan. Data yang diperlukan untuk analisa ketersediaan air adalah data debit sungai bulanan atau harian dengan periode waktu lebih besar dari 10 tahun, dimana data ini tidak ada sehingga debit bulanan di-simulasikan berdasarkan data hujan dan data evapotranspirasi potensial pada daerah penelitian dengan bantuan model matematik hubungan hujan-limpasan. Model hubungan hujan-debit dengan interval bulanan yang digunakan adalah NRECA. Dari Metoda Ke-tersediaan Air/Debit andalan DAS Barito Hulu menggunakan debit hasil perhitungan Me-tode Nreca menunjukan bahwa debit andalan 80% didapat rata-rata per bulan 349,853 m3/detik, dan 85% didapat rata-rata per bulan 261,675 m3/detik. Ketersediaan Air/Debit Andalan 90% didapat rata-rata per bulan 167,094 m3/detik. Ketersediaan air 95% di-dapat rata-rata per bulan 97.384 m3/detik, dan 99% didapat rata-rata per bulan 69,170 m3/detik
The changes in TVN and histamin of kilka within the different preservation methods
The purpose of this research was to evaluate the quality of preserved kilka for human consumption. The different preservation methods (CSW and crushed ice) were used and the results were compared with the traditional method. Two main parameters (TVN and Histamine) of collected samples were measured in different preservation-time, namely: a) Time zero (after fishing), b) T5 and T10 (5 and 10 hours duration from fishing ground to processing room). The mean value of Histamine of T10 (10 hours after fishing) for traditional, CSW and crushed ice methods were determined 10.3, 2.2 and 1.5mg/100, respectively. On the other hand, the measured TVN values above mentioned methods were 22.3, 19.0 and 17.0 mg/100, respectively. The results showed a significant difference between the traditional method and two other methods (P<0.05) but (here was no significant between CSW and crushed ice methods. Since, the preserved kilkas in the CSW showed higher quality, therefore, it is proposed that tor using kilka as human consumption, they showed be preferably preserved in chilled sea water after fishing
An outpatient department based observational study to review the pattern of utilization of proton pump inhibitors for their co-relation with the indications in a tertiary care centre
Background: Proton pump inhibitors (PPIs) are one of the commonest drugs prescribed for a variety of indications. They are considered remarkably safe and prescribed liberally. However, on long term administration, they can cause a number of adverse effects. In a tertiary care hospital, where the patient numbers are large and many attending super speciality centre, a number of patients were observed to receive PPIs for approved and unapproved indications. It was therefore considered prudent to study the prescribed PPIs for a co-relation with their indications or otherwise so as to formulate corrective interventions.Methods: The observational study was conducted in the dispensary of a tertiary care centre. The prescriptions of the patients were the study material. Prescriptions for a full week were taken in for consideration. A total of 4142 prescriptions were studied. All aspects related to PPIs were noted and analysed. Additionally, a note on prescribed calcium supplements, vitamins and antioxidants was made.Results: Of all the prescriptions studied by us, 33% had PPIs in them. Omeprazole was the commonest PPI followed by pantoprazole. Almost half the patients prescribed PPIs, the duration of administration was over 30 days. 78% patients prescribed PPIs also had some or the other non-steroidal anti-inflammatory drug (NSAID) in their prescription. Over one fourth of the total patients also received calcium supplements, vitamins or anti-oxidants.Conclusions: Proton pump inhibitors are very popular drugs and are being prescribed for approved and unapproved indications in the hope of providing relief to the patients. They are being advised quite liberally and more so if any NSAID has been co-prescribed. Even for prescriptions lasting for less than 5 days, PPIs have been included in the presumption to prevent gastritis due to NSAIDs. This practice is contrary to guidelines and also exposes the patients to avoidable adverse drug reactions
Entropy as logarithmic term of the central charge and modified Friedmann equation in AdS/CFT correspondence
This paper is about the extended thermodynamics of AdS black holes and its
relation to CFT thermodynamics. The logarithmic term of the central charge is
interpreted as black hole entropy. We have obtain a modified Friedmann equation
from the Smarr formula. We find that the AdS radius is the critical shadow
radius. We obtain the Hawking-Bekenstein formula with logarithmic corrections,
which depends on the central charge. The real gas in AdS is a dual of an ideal
gas in CFT. This work can be extended to the AdS-Kerr black holes.Comment: 22 pages, 4 figure
Possible signatures of mixed-parity superconductivity in doped polar SrTiO3 films
Superconductors that possess both broken spatial inversion symmetry and
spin-orbit interactions exhibit a mix of spin singlet and triplet pairing.
Here, we report on measurements of the superconducting properties of
electron-doped, strained SrTiO3 films. These films have an enhanced
superconducting transition temperature and were previously shown to undergo a
transition to a polar phase prior to becoming superconducting. We show that
some films show signatures of an unusual superconducting state, such as an
in-plane critical field that is higher than both the paramagnetic and orbital
pair breaking limits. Moreover, nonreciprocal transport, which reflects the
ratio of odd versus even pairing interactions, is observed. Together, these
characteristics indicate that these films provide a tunable platform for
investigations of unconventional superconductivity
The Psychological Impact of Referral for Mammography Screening for Breast Cancer Among Women in Muscat Governorate: A cross-sectional study
Objectives: Breast cancer constitutes the majority of diagnosed cancers in Oman’s females, accounting for 19.2%, which prompted the introduction of a breast cancer screening programme into the Omani healthcare system. There are rising international concerns about the effectiveness of mammography as a screening tool and its psychological impact. The current study aimed to determine the social, emotional and physical dysfunction caused by the waiting time from the day of scheduling the appointment until the day of screening and explore associated risk factors. Methods: This cross-sectional study was conducted between March and December 2017 at Khoula Hospital, Muscat, Oman, using a two-part self-administered questionnaire. Part one of the questionnaire collected clinical and demographic data. Part two consisted of the Psychological Consequences Questionnaire (PCQ) and focused on psychological consequences, measuring the effect of mammographic screening on emotional, physical and social functions. Results: A total of 300 women aged ≥40 years old participated in this study (response rate: 100%). Results revealed that there was a minimal negative psychological impact from screening using mammograms. All PCQ domains were significantly impacted for participants who reported a family history of cancer (P = 0.007). The social score was significantly higher among women between 40–50 years old (P = 0.008). Scores of emotional and social functions were significantly affected by participants’ employment status; employed women were more affected than those who were not (P = 0.043 and 0.012, respectively). However, women’s levels of literacy did not affect any of the domains. Conclusion: The psychosocial impact of the waiting period between scheduling and undergoing mammography screening was minimal in the current sample. Future research should evaluate the psychosocial impact on patients at different recall times.Keywords: Breast Cancer; Mammography; Psychological Factors; Depression; Anxiety; Oman
An analysis of adherence to the World Health Organisation guidelines pertaining to drug promotional literature by pharmaceutical firms
Background: Pharmaceutical companies used Drug Promotion Literatures (DPLs) as a major tool to advertise their new products. World Health Organization (WHO) has set some guidelines for promotion of drug literature. Thus, this study aimed to evaluate various DPLs for their accuracy and credibility as per WHO ethical criteria.Methods: This was an observational and cross-sectional study. Total 100 drugs advertisements published in various medical journals were collected from the library of the college. Advertisements were selected based on inclusion and exclusion criteria. The selected advertisements were evaluated based on the WHO ethical criteria for drug promotion.Results: From 100 advertisements, 73 were single drug whereas 27 were fixed drug combinations. Antimicrobials (16%) were the most promoted advertisements. Only 28% of the advertisements carried references to support their claim. Out of which majority (91.78%) were from journal articles. The generic name, brand name, names of active ingredients, manufacturer, distributor and dosage regimen were mentioned in majority of advertisements. Drug interactions (12%), contraindications (22%), precautions (24%) and side effects (22%) were least mentioned in the advertisements.Conclusions: It was observed that none of the advertisement followed all the guidelines laid down by WHO. Pharmaceutical companies should follow ethical regulatory measures to promote their product in various journals. The regulatory authority must ensure the pharmaceutical companies to follow ethical guidelines for publishing various drug promotional literatures
