Authors: Djarot Prasetyorini , . Moerfiah , Ambarwati Dwi 
Published: January 2020

This research was aimed to create aromatic candle, infused with cinnamon (Cinnamomum burmanii) bark essential oil, which is a potential repellant for house fly (Musca domestica). The distillation of akar wangi samples was carried out at the Spice and Aromatic Research Unit by vapor distillation method for 9-12 hours. The aromatic candles were based on a mixture of solid paraffin and stearin in a 2:8 proportion, respectively, enriched with fragrant root bark essential oils with 5 formulas, namely F1 (placebo), F2 (fixative), F3 (1% essential oil), F4 (2% essential oil), and F5 (3% essential oil). The repellency test was carried out by inserting 20 house flies in a of 50x50x50 cm container that contains a lighted aromatic candle according to the doses mentioned above, and shrimp scalps located 15 cm from the candle that functions as a bait. The calculated parameters were the hourly number of flies that were allured to the bait for 6 hours, which were related to the candle’s repellency and the house fly’s preference of candle. The repulsion ability result were 89.724%, 75.28%, 68.06%, 49.17%, 9.72% for F5, F4, F3, F2, and F1, respectively. The result also showed that the F4 sample was the most preferred sample.

Adsorpsi Metilen Biru Pada Hidroksiapatit Dari Tulang Ikan Kakap MerahABSTRAKPenelitian yang bertujuan untuk mempelajari adsorpsi metilen biru pada hidroksiapatit yang diperoleh dari tulang ikan kakap merah (Lutjanus sp.) telah dilakukan. Tulang dikalsinasi dalam tanur pada 600, 800, dan 1000 oC, digerus, dan diayak dengan ayakan 100 mesh. Material tersebut selanjutnya digunakan dalam eksperimen adsorpsi dan data yang diperoleh dianalisis menggunakan model isoterm adsorpsi Langmuir, Freundlich, dan Dubinin-Raduskevich. Hasil penelitian menunjukkan bahwa semakin tinggi suhu kalsinasi, semakin rendah kapasitas adsorben untuk mengadsorpsi metilen biru. Energi adsorpsi yang dihitung berada dalam kisaran 0,84-1,14 kJ mol-1 yang mengindikasikan bahwa metilen biru teradsorpsi secara fisik pada adsorben dan adsorpsi cenderung mengikuti model isoterm adsorpsi Freundlich.Kata kunci: adsorpsi, hidroksiapatit, kakap merah, metilen biru Adsorption of Methylene Blue on Hydroxyapatite from Red Snapper Fish Bones ABSTRACTA research aimed to study the adsorption of methylene blue on hydroxyapatite obtained from red snapper fish bones (Lutjanus sp.) was performed. The bones were calcined in a furnace at 600, 800, and 1000 oC and ground to pass a 100 mesh sieve. The materials were used in the adsorption experiment and the data obtained were analyzed using Langmuir, Freundlich, and Dubinin-Raduskevich adsorption isotherm models. The results showed that the higher the calcination temperature, the lower the capacity of the adsorbent to adsorb methylene blue. Calculated adsorption energy which was in a range of 0.84-1.14 kJ mol-1 indicated that the dye was adsorbed physically on the adsorbent and the adsorption could be well described by Freundlich adsorption isotherm model.Keywords: adsorption, hydroxyapatite, red snapper, methylene blue
The outcomes of Skeletonized and Pedicled Internal Thoracic Artery in Patients undergoing coronary artery bypass grafting: a randomized clinical study
Authors: Shaheen Yousry A , Ahmad El-Shafiey Mahmoud , Hebishy Mostafa Galal , Sobhy Emara Ahmad 
Published: January 2020

Background: Internal thoracic artery became the cornerstone graft in coronary artery bypass grafting. This study aimed to investigate sternal healing and wound infection in patients undergoing coronary artery bypass graft (CABG) surgery using skeletonized versus pedicled internal thoracic artery.
Methods: 100 patients who underwent isolated CABG were divided into two groups; skeletonized internal thoracic artery (ITA) (50 patients) and pedicled internal thoracic artery (50 patients). The postoperative assessment was performed three months after surgery. Physical and radiological examinations were performed after surgery to assess sternal healing.
Results: There was no significant difference in patients’ demographics between groups. Skeletonized group had more diabetic patients (65% vs 44%; p= 0.016). There was no significant difference between the two groups regarding the number of grafts (2.72 ± 0.89 vs. 2.68 ± 0.90; skeletonized vs pedicled group; p= 0.84). Harvesting time was longer in the skeletonized group (55.69 ± 8.80 vs. 44.28 ± 6.95 minutes; p=0.09). Superficial wound infection occurred more frequently in the pedicled group (24% vs. 8%; p=0.03).
Conclusion: Skeletonization of the internal thoracic artery conduits lowers the risk of superficial and deep sternal wound infection in patients undergoing CABG compared to the pedicled technique. However, skeletonization of internal thoracic artery conduits prolongs the operation time and requires more surgical skills.

Published: January 2020

Background: Acute kidney injury is a serious complication after coronary artery bypass grafting (CABG). This work aimed to assess the impact of the timing of coronary angiography on kidney function after on-pump coronary artery bypass grafting.

Methods: We included 60 patients who underwent elective isolated on-pump coronary artery bypass grafting from 2017 to 2018 at the National Heart Institute and Benha University Hospital. We divided the patients into two groups; group І included 30 patients with coronary angiography performed less than seven days prior to CABG, and Group ІІ included 30 patients who had coronary angiography more than seven days prior to CABG. Postoperative acute kidney injury was defined according to the consensus kidney disease: Improving Global Outcomes Definition and Staging criteria.
Results: The mean body mass index was significantly higher in group I (35.89±5.15 Kg/ m² vs. 31.72±4.99 Kg/ m², P = 0.002). The mean preoperative hemoglobin was higher in group II (12.7 ± 1.5 g/dl vs. 13.9 ± 1.5 g/dl, P = 0.004). The frequency of acute kidney damage was higher in patients who had coronary angiography less than seven days before CABG but did not reach a significant level (46.7 % vs. 30%, P =0.184). There was no difference in the creatinine postoperatively between both groups (1.2 ±0.5 vs. 1 ±0.3 mg/dl; p= 0.214).
Conclusions: We found no association between the timing of coronary angiography before on-pump coronary artery bypass graft surgery and postoperative acute kidney injury.

Published: January 2020

Background: Surgical treatment modalities of coronary artery diseases (CAD) include on-pump or off-pump coronary artery bypass grafting (CABG). CABG performed on the beating heart can avoid complications that might occur on cardiopulmonary bypass. Our objective was to compare the effectiveness of on-pump versus off-pump CABG in high-risk patients stratified according to the EuroSCORE scoring system.
Methods: This randomized clinical study included 80 high-risk patients who underwent CABG and assigned into two groups; each contains 40 patients. Patients with valvular affection, ischemic ventricular septal defect or left ventricle and aortic aneurysms, and/or those exhibiting significant neurological pathology were excluded from the study. Study outcomes were blood loss, length of ICU and hospital stay, inotropic use, re-exploration rate, and operative mortality.
Results: The study showed significant higher use of inotropic drugs intra and post-operatively (57.5% vs 40%, p = 0.021), more low cardiac output (12.5% vs 2.5%, p = 0.031), lower blood loss (337±67 vs 498±68 ml, p = 0.01), lower blood transfusion (1.1±0.2 vs 1.2±0.4 unit, p = 0.024), more prolonged ICU stay (4.0±1.6 vs 3.0±0.9 day, p = 0.001) and the higher re-exploration rate (17.5% vs 7.5%, p = 0.035) in the on-pump group. Hospital stay (8.7±2 vs 8.1±1, p = 0.121) and early mortality (7.5% vs 2.5%, p = 0.451) did not differ significantly between the two groups.
Conclusion: Management of coronary artery disease is still challenging, and there is still a place for off-pump CABG in CAD in high-risk patients due to its advantages in the early complications while has the same total hospital stay when compared with on-pump CABG.

Analysis of Line Outage Detection in Nigeria 330kV Transmission Lines using Phasor Measurement Units
Authors: Obodoagwu Nkem Francis 
Published: January 2020

In this work, an analysis of line outage detection in Nigeria 330kV transmission lines using Phasor Measurement Units was presented. This requires collection and analysis of the data obtained from Transmission Company of Nigeria with the aid of PSAT 2.10.1 / MATLAB SIMULINK using Newton-Raphson power flow algorithm and also to determine the effectiveness of PMU when introduced in our power system network. 12 buses and 3 Generators system were considered for the studied. This was achieved by collecting relevant transmission parameters for 330kV line and was simulated on PSAT 2.10.1 and MATLAB 2015a using Newton-Raphson power flow algorithm. The work involved an offline and online analysis. For the offline analysis the admittance / impedance matrix for Y-bus and bus voltage for pre-outage was obtained via the power flow analysis and change in impedance for the lines were calculated. These values were further normalised in order to reduce the value to a row echelon form. Then for the online analysis; the change in phase angle from the Phasor Measurement Unit (PMU) online simulation for pre-outage and also post-outage was calculated and a normalised column matrix was gotten. Finally, the effectiveness of the line outage detection was graphically represented using MATLAB software to plot the values of the normalised values of the offline and online analysis; i.e., by comparing the normalised form of the offline and online values. These results clearly show that PMUs gives an accurate monitoring and total observability when introduced in Nigeria power system.
‘Met wijsheid, voorzichtigheid en gematigdheid vooruitgaan’

Abstract
Between 1908 and 1966 the Dutch Jesuits founded five retreat institutions in the Netherlands to support the laity with spiritual care and to enable them to undergo (a part of) the Spiritual Exercises of Ignatius van Loyola (the founder of the Jesuits). Notwithstanding the enormous popularity of these retreat activities, especially in the first half of the twentieth century, this phenomenon has hardly been subject to academic research. With this article, being a part of my postdoc-research project at Tilburg University, I hope to give a start to this study. At the turn of the century, the group retreat work the Dutch Jesuits introduced for the male laity in the Netherlands originated in Belgium and France. During the years to follow this work became exceptional popular among Catholics living in the southern provinces of the Netherlands. Due to a high organisational level of Catholic social and political institutions and the involvement of the Catholic upper-class and local parish priests the propaganda of the Jesuits for their retreat work in the Southern provinces was extremely effective. The (industrial) employers as well as the Jesuits regarded the retreat work as a splendid opportunity to ‘civilize’ the Catholic working-class and to keep them away from communism and socialism. As a consequence of new theological and spiritual insights, after World War II things started to change in the traditional retreat work. In the fifties and sixties the retreats were transformed into meetings of spiritual reflection and counselling, at last becoming socio-cultural training courses from the seventies onwards. The lack of a straightforward underlying theological vision for these transitions on which all Jesuits could agree on, the rising costs, and the declining number of Jesuits members, resulted in 1974 in the ending of their participation in this group-organized work. However, retreats given on an individual basis continued and from the nineties new initiatives were launched to popularize the Spiritual Exercises using digital techniques and the internet.
Political Mission of the ‘Clericalized Laity’
Authors: Beentjes Simon 
Published: January 2020

Abstract
This article addresses the political engagement of Catholic students in the Netherlands during the inter-war period. Recently there has been an increased academic interest both nationally and internationally, in juvenile and radical Catholicism in the inter-war years. In the Netherlands, the magazine De Gemeenschap and the girls’ movement De Graal are important examples of the radical Catholicism of the youth. Though the religious activism of these Catholic youth groups has been studied extensively, we still do not know much about their involvement in politics and more specifically, their interaction with the Catholic party. This article looks at how the activation of the laity affected the political engagement of Dutch Catholic students. Based on ideas about Catholic Action and the importance of a lay apostolate for the rechristianization of society, Catholic students established new groups for religious and political activism. As these groups were neither installed nor controlled by the hierarchy, they formulated alternative political interpretations of Catholicism. Thus, the youth challenged the religious legitimacy of the Catholic party, whose politicians listened to them only reluctantly.
Financial Mismatch, Assets Specificity and Capital Structure
Authors: Li Yanwu 
Published: January 2020

At present, the problem of financial mismatch poses great challenge to China’s financial market. Financial mismatch blurs the market governance structure of debt financing, thus distorting the relationship between asset specificity and capital structure. This paper investigates companies listed on the A-share of Shanghai and Shenzhen Stock Exchange from 2012 to 2017. It tests the existence of financial mismatch and the impact of financial mismatch on asset specificity and capital structure. Empirical results show that the impact of financial mismatch on the relationship between asset specificity and capital structure of sample companies exhibits no differences in ownership. Both state-owned listed companies and private companies face the same degree of financial mismatch issues, which leads to changes in the property-specific governance structure of assets, and asset specificity is positively related to capital structure.
Urban Heat and Burden of Hyponatremia

ImportanceHyponatremia (sodium level &amp;lt;135 mEq/L), the most prevalent electrolyte disorder in clinical practice, is associated with considerable clinical and economic burdens. Despite its recognized effect and indication of seasonal patterns, there is a research gap regarding heat-related hyponatremia. Addressing this issue is crucial, especially regarding projected increases in environmental temperature, particularly in urban areas.ObjectiveTo comprehensively analyze the association of heat in an urban setting with hyponatremia prevalence.Design, Setting, and ParticipantsThis cross-sectional study using retrospective time series analysis was conducted among all adult patients (age ≥18 years) presenting to the Charité–Universitätsmedizin Berlin between March 1, 2000, and August 31, 2023, with a blood sodium measurement.ExposureThe daily heat index, which accounts for both outdoor air temperature and relative humidity.Main Outcomes and MeasuresThe primary outcome measure was the daily number of hyponatremia cases, further categorized by severity. Differences in prevalence across age groups (adult patients, aged 18-65 years; and older patients, aged &amp;gt;65 years) and sexes were also examined.ResultsA total of 7 135 688 sodium measurements from 2 028 537 hospital visits were analyzed. The mean (SD) age at admission was 57.8 (17.8) years, and 51.7% of patients were male. A clear seasonal pattern of heat-related hyponatremia was evident among older patients, especially for moderate (sodium level, 125-129 mEq/L) and severe hyponatremia (sodium level, &amp;lt;125 mEq/L), where the cumulative risk over a lag period of 5 days reached a maximum relative risk (RR) of 1.26 (95% CI, 1.07-1.48) when the heat index reached 30 °C, compared with the temperature at which hyponatremia occurred least frequently. Older women were disproportionately more likely to experience hyponatremia compared with older men, with a cumulative RR of 1.10 (95% CI, 1.03-1.18) at a heat index of 26 °C. The highest RR was on lag day 0 for all subgroups (older patients: RR, 1.04 [95% CI, 1.00-1.08]; moderate and severe hyponatremia in older patients: RR, 1.05 [1.01-1.10]; and older women: RR, 1.07 [95% CI, 1.01-1.12]) and significantly increased when the heat index exceeded 15 °C (RR, 1.01 [95% CI, 1.00-1.02]).Conclusions and RelevanceThis cross-sectional study of patients with sodium measurements suggests that older people, especially women, were vulnerable to heat-related hyponatremia. Environmental heat was associated with an immediate exacerbation of hyponatremia. This finding highlights the importance of implementing prevention strategies to mitigate heat-related hyponatremia, as an increased burden in the future due to climate change is likely.

Published: December 2024

Abstract
Here, inhomogeneous waves, and, in particular, leaky waves are initially described and natural phenomena that can be expressed in terms of inhomogeneous improper waves are also introduced. The description of the physical properties of inhomogeneous waves and leaky waves and their physical characteristics will finally allow us to describe the propagation features and the radiation patterns generated by leaky‐wave antennas (LWAs), as they are conventionally defined in terms of leaky waves. Furthermore, this chapter will go into the description of LWAs families and features.
