Published: October 2021

Dalam merencanakan dan merealisasikan pembangunan berkelanjutan diperlukan totalitas dari tim proyek, salah satunya dengan menerapkan manajemen sisa bangunan akibat tahap konstruksi dan perusakan bangunan. Manajemen sisa bangunan atau Waste Management penting diperhatikan oleh pelaksana pembangunan (dalam hal ini kontraktor) dimulai pada saat estimasi hingga pelaksanaan di lapangan. Hal ini dilakukan agar limbah yang dihasilkan dapat seminimal mungkin dan tentunya berpengaruh pada efisiensi penggunaan material dan biaya yang akan dikeluarkan untuk pengadaan material maupun pengelolaan dan pengolahan limbahnya. Tujuan penelitian ini adalah untuk mengetahui faktor-faktor yang perlu diperhatikan dalam penerapan waste management pada proyek konstruksi dan penanganan sisa material konstruksi dari proses pembangunan. Pada pelaksanaannya pengambilan data dilakukan dengan penyebaran kuisioner di lapangan kepada 40 project manager dan pengamatan di lapangan yang dibatasi pada pekerjaan pemotongan besi untuk penulangan kolom, balok dan plat lantai serta pengecoran. Pengamatan masing-masing dicari 15 data pengamatan yang mewakili. Perhitungan kuisioner menggunakan analisis deskriptif sedangkan untuk mendapatkan sisa material pemotongan besi dan pengecoran digunakan perhitungan sederhana. Dari hasil penyebaran kuisioner diketahui bahwa klasifikasi peringkat tertinggi dalam penerapan waste management pada proyek konstruksi adalah reduce (pelatihan kepada pekerja dalam penggunaan peralatan seefisien mungkin).

Effects of nutrient enrichment and skewed N:P ratios on physiology of scleractinian corals from Weizhou Island in the northern South China Sea
Authors: Ning Z , Yu K , Wang Y , Wei F , Liao Z , Yang B , Fang C , Xia R , Huang X , Song G
Published: October 2021

The availability of nitrogen (N) and phosphorus (P) is crucial for maintaining coral-dinoflagellate symbiosis, whereas excess nutrients and skewed N:P ratios are often associated with coral reef decline. It is thus essential to understand the general patterns of species-specific as well as dose-dependent responses of corals to elevated nutrient concentrations and skewed N:P ratios. Here, we found that the impacts of nutrient enrichment on the corals Acropora millepora and Platygyra crosslandi from Weizhou Island, South China Sea, were highly dependent on nutrient dose, N:P ratios, and coral species. Moderate nutrient enrichment (N: 19-140 µmol l-1 and P: 0.5-1.5 µmol l-1) did not lead to bleaching of either coral species, but their metabolic processes (calcification, nutrient uptake, and dinitrogen fixation) were affected. More depleted δ13C and lower dinitrogen fixation rates of A. millepora than of P. crosslandi indicated that A. millepora was more vulnerable to the disturbance of nutrient enrichment. However, N:P ratios (±SD) as high as 106 ± 10 decreased the photosynthetic efficiency and nutrient uptake rates of P. crosslandi, indicating that this species may be vulnerable to high N:P ratios, although it was one of the dominant coral assemblages at Weizhou Island. The results provide an important basis for understanding coral reef degradation triggered by nutrients and a suggestion that coastal management should focus not only on the concentrations but also on the ratios of nutrients.
Direct and indirect effects of resilient pastures at farm scale
Authors: Jagger Murray
Published: October 2021

I farm a 550-ha property at coastal Whangarei Heads, Northland, in partnership with my wife Helen. While some land has been in family ownership since the 1850s, our farm has grown over the years through land and farm acquisitions. The farm consists of a dairy platform of 220 ha and 330 ha of dairy beef and dairy support. The farm is kikuyu dominant and summer dry with rainfall varying between 650 and 1100 mm per annum. Summer cropping, in-shed meal feeding, sowing Italian ryegrass and kikuyu mulching are all practices used with the aim of running a sustainable system. Perennial ryegrass pastures have limited persistence and are no longer a focus as more resilient pasture species and varieties are sown.
ANAYASACILIK BAĞLAMINDA İSLAMİ ANAYASACILIK KAVRAMI VE MEDİNE VESİKASI
Authors: KESKİN Erdoğan
Published: October 2021

Bu çalışmada, liberalizmin bir eseri olan anayasacılık düşüncesinin yanı sıra İslami anayasacılık fikrinin mümkün olup olmadığı incelenmektedir. Nitekim anayasacılık, liberal düşünürler ve fikirler etrafında ortaya çıkmıştır. Dolayısıyla bir başka ideoloji ya da inanca özgü bir anayasacılıktan bahsedilebilir mi sorusu, cevaba muhtaç bir sorudur. Çalışmada ele alınan diğer bir ana konu ise birçok yazar tarafından anayasa olarak ifade edilen ve değerlendirilen Medine Vesikası’dır. Anayasa kavramının anlamı, Vesika’nın kabul edildiği dönem şartları ve ortaya çıkışı; bu yazarların iddialarının doğruluğunun tespiti açısından değerlendirilmesi gereken hususlardır. Zira anayasa kavramı, anayasacılıktan bağımsız düşünülemeyeceğinden gerek İslami anayasacılık söylemleri gerekse Vesika’nın anayasa olduğuna dair iddialar birbirinden bağımsız değildir. Bu nedenle çalışmada her iki konu birlikte incelenmiştir. Çalışma gerek İslami anayasacılık iddialarının gerekse Medine Vesikası’nın anayasa olduğuna dair iddiaların değerlendirilmesini ve konunun özünden ayrılmayarak bu fikirlerin yerinde olup olmadığının tespit edilmesini amaçlamaktadır. Bu bağlamda çalışmanın anayasacılık ve anayasa kavramlarının anlaşılması açısından yeni soluk getirmeyi amaçladığını ifade etmek mübalağalı olmasa gerek.

El objetivo de la investigación fue evaluar la inclusión de cinco niveles de cáscara de maracuyá 0, 5, 10, 15 y 20% en ensilaje de pasto elefante, almacenados durante 30 días en tubos de PVC de capacidad de tres kilogramos. Se aplicó un diseño de bloques completos al azar con cinco tratamientos y tres bovinos con rumen fistulado y siete tiempos de incubación (0, 3, 6, 12, 24, 48 y 72 horas). Las diferencias entre medias de tratamientos se establecieron mediante la prueba de Tukey (p<0.05). Los valores de la DMSIS en los tiempos 0, 3, 6, 12, 24 y 48 horas de incubación no presentaron diferencia (P>0.05), en todos los tratamientos que se incrementó el residuo de maracuyá en el ensilaje de pasto elefante aumentó la desaparición de la materia seca con el paso del tiempo de incubación de la muestra en el rumen. La DMSIS a las 72h fue 72.67% en el T1 superior (P<0,05) a los demás tratamientos lo que indica la importancia de los carbohidratos estructurales de fácil digestión en la digestibilidad total de la MS. Esta tendencia de degradación puede deberse principalmente a los contenidos similares de la composición química del pasto elefante y residuo de maracuyá, especialmente del contenido de FDN y FDA ya que estas fracciones de fibra son indicadores indirectos de la digestibilidad.

In addition to the extensive functional study of Ku70 in DNA repair process, many studies have emphasized the role of Ku70 in various other cellular processes, including apoptosis, aging, and HIV replication. In this review, we focus on discussing the role of Ku70 in inducing interferons and proinflammatory cytokines as a cytosolic DNA sensor. We explored the unique structure of Ku70 binding with DNA; illustrated, with evidence, how Ku70, as a nuclear protein, responds to extracellular DNA stimulation; and summarized the mechanisms of the Ku70-involved innate immune response pathway. Finally, we discussed several new strategies to modulate Ku70-mediated innate immune response and highlighted some potential physiological insights based on the role of Ku70 in innate immunity.

Introduction: Asherson's Syndrome, also defined as Catastrophic Antiphospholipid Syndrome (CAPS), represents the most severe manifestation of Antiphospholipid Antibody Syndrome. Rarely, the first CAPS diagnosis is based on macro-thrombotic event as acute limb ischemia.

Case Presentation: We present a case of a 65-year-old woman admitted with an acute lower limb arterial ischemia with a complete occlusion of all the three tibial vessels. Three endovascular recanalization procedures were performed contemporary to 48 h intraarterial thrombolysis administration. The patency of tibial arteries was restored with a near-complete absence of digital arteries and microvessel perfusion of the foot. In the following days, an aggressive foot gangrene was established, leading to a major lower-limb amputation. Due to the general clinical status worsening and aggressiveness of ischemic condition, further investigations were performed leading to the diagnosis of an aggressive Asherson's Syndrome that was also complicated by a severe heparin-induced thrombocytopenia. Medical management with a high dose of intravenous steroids and nine sessions of plasma exchange led to a clinical condition stabilization.

Conclusion: In our case, the presence of a “sine causa” acute arterial occlusion of a large vessel represented the first manifestation of an aggressive form of Asherson's Syndrome that could represent a fatal disease. Due to the extreme variety of manifestations, early clinical suspicion, diagnosis, and multidisciplinary management are essential to limit the life-threatening consequences of patients.

Objective: We aimed to: (1) explore the risk factors that affect the prognosis of cardiac surgery-associated acute kidney injury (CS-AKI) in patients undergoing renal replacement therapy (RRT) and (2) investigate the predictive value of the Acute Physiology and Chronic Health Evaluation (APACHE) III score, Sequential Organ Failure Assessment (SOFA) score, and Vasoactive-Inotropic Score (VIS) for mortality risk in patients undergoing RRT.

Methods: Data from patients who underwent cardiac surgery from January 2015 through February 2021 were retrospectively reviewed to calculate the APACHE III score, SOFA score, and VIS on the first postoperative day and at the start of RRT. Various risk factors influencing the prognosis of the patients during treatment were evaluated; the area under the receiver operating characteristics curve (AUCROC) was used to measure the predictive ability of the three scores. Independent risk factors influencing mortality were analyzed using multivariable binary logistic regression.

Results: A total of 90 patients were included in the study, using 90-day survival as the end point. Of those patients, 36 patients survived, and 54 patients died; the mortality rate reached 60%. At the start of RRT, the AUCROC of the APACHE III score was 0.866 (95% CI: 0.795–0.937), the VIS was 0.796 (95% CI: 0.700–0.892), and the SOFA score was 0.732 (95% CI: 0.623–0.842). The AUCROC-value of the APACHE III score on the first postoperative day was 0.790 (95% CI: 0.694–0.885). After analyzing multiple factors, we obtained the final logistic regression model with five independent risk factors at the start of RRT: a high APACHE III score (OR: 1.228, 95% CI: 1.079–1.397), high VIS (OR: 1.147, 95% CI: 1.021–1.290), low mean arterial pressure (MAP) (OR: 1.170, 95% CI: 1.050–1.303), high lactate value (OR: 1.552, 95% CI: 1.032–2.333), and long time from AKI to initiation of RRT (OR: 1.014, 95% CI: 1.002–1.027).

Conclusion: In this study, we showed that at the start of RRT, the APACHE III score and the VIS can accurately predict the risk of death in patients undergoing continuous RRT for CS-AKI. The APACHE III score on the first postoperative day allows early prediction of patient mortality risk. Predictors influencing patient mortality at the initiation of RRT were high APACHE III score, high VIS, low MAP, high lactate value, and long time from AKI to the start of RRT.

Background: Obesity is an independent risk factor for cardiovascular disease. We investigated whether and to what extent visceral obesity-related indices were associated with coronary collateralization (CC) in chronic total occlusion (CTO) patients.

Methods: This retrospective cohort study involved 1,008 consecutive patients with CTO who underwent CTO-percutaneous coronary artery intervention (PCI). CC was graded according to the Rentrop scoring system. Data on demographic and clinical characteristics were collected by cardiovascular doctors. Logistic regression, receiver operating characteristic (ROC) curve and Kaplan-Meier analyses were performed to assess the predictive value of visceral obesity-related indices for CC.

Results: Overall, 1,008 inpatients were assigned to the poor CC group (n = 592) and good CC group (n = 416). In multivariate-adjusted logistic regression analyses, all visceral obesity-related indices (P-value < 0.001) were significantly associated with CC. After ROC analysis and the Delong test, the Chinese visceral adiposity index (CVAI) had the largest area under the curve (AUC) of 0.741 (0.711–0.771). Further analysis revealed that CVAI quartile remained a risk factor for poor CC in all groups, CVAI was associated with a 1.018-fold higher risk of poor CC (OR = 1.018, 95% CI: 1.014–1.021, P < 0.001). Individuals in the top CVAI quartile group had the highest risk of poor CC (OR = 10.657, 95% CI: 6.492–17.493, P < 0.001). Subgroup analyses showed similar results, and CVAI quartile remained a risk factor for poor CC. Moreover, increased CVAI predicted poor prognosis in CTO patients.

Conclusion: In summary, this study indicated that all the increased visceral obesity-related indices were significantly associated with increased poor CC risk. After adjusting for potential risks, CVAI had the best performance for estimating CC and predicting prognosis in CTO patients.
A Delayed Anatomic Diagnosis and Management Challenge in an Initially Asymptomatic Infant With Type II Pulmonary Artery Sling: A Case Report

Pulmonary artery sling (PAS) is a rare but fatal malformation. Patients with PAS tend to develop obstructive symptoms in few weeks of life. Conversely, some patients may be otherwise mild or asymptomatic in their early life. Currently, no consensus on the intervention timing and treatment strategy for asymptomatic and mild cases has been reached. Moreover, the extent of tracheal stenosis is another determining factor for the choice of intervention timing since clinical symptoms might not correspond well with the degree of stenosis. Lack of comprehensive assessment of entire airways confer underestimation of disease severity and in turn improper choice of treatment regimens and poor outcomes. Herein, we described an infantile case of PAS, who was scheduled initially for periodic outpatient follow-up on account of the absence of symptoms and inadequate imaging assessment at diagnosis. The patient developed recurrent wheezing and progressive respiratory distress at 7 months of age. After left pulmonary artery (LPA) reimplantation without tracheal intervention, bronchoscopy was performed due to failure to wean from mechanical ventilation, which demonstrated complete tracheal cartilage rings, a long segment tracheal stenosis, a low tracheal bifurcation at T6, and the absence of a separate right middle lobe bronchus. The patient was finally diagnosed with type IIb PAS and extubated successfully following conservative treatment. Miserably, neurological sequelae were devastating, leading to poor outcomes. Comprehensive airway evaluation using bronchoscopy is substantial to early identification of all components responsible for airway compromise in PAS anatomic subtypes. Considering severe concomitant maldevelopment of the bronchial tree in children with type IIb PAS, early and complete correction by surgery might decrease perioperative morbidities and mortalities of these patients.

Introduction: Augmented reality (AR) technology has demonstrated potential on various areas of healthcare practice. Its role on medical education is starting to emerge. This study aimed to investigate students’ perspectives on using AR as learning tools in undergraduate pharmacy education.

Methods: Four AR micro modules on post-stroke management and chronic obstructive pulmonary disease (COPD) were developed for third year undergraduate pharmacy students to study. Students played the role of pharmacists in the AR micro modules. They collected information to identify patient’s chief complaints, history, risk factors, comorbidities, and other problems, and provided recommendation on patient’s treatment plans. Teacher guided the discussions and addressed student’s enquiries. Student’s feedback was collected by pre- and post-intervention survey.

Results: A total of 54 students participated in the current study. The was no significant change in students’ perceived knowledge on post-stroke management and COPD, as well as their confidence in providing patient counselling on relevant topics. Students expressed that their learning experience with AR was not positive. Technical problems were the major difficulties that students encountered.

Conclusion: There was no significant difference in pharmacy students perceived clinical knowledge and confidence on patient’s counselling after completing the AR modules. Technical issues were the major hurdles that hindered student’s learning experience with AR.

The alcohol industry discharges large quantities of wastewater, which is hazardous and has a considerable pollution potential. Cultivating microalgae in wastewater is an alternative way of overcoming the current high cost of microalgae cultivation and an environmentally friendly treatment method for industrial effluents. The study analyzed the growth and biochemical composition of Chlorella vulgaris cultivated in membrane-treated distillery wastewater (MTDW) and nutrients removal efficiency. The results showed biomass productivity of 0.04 g L−1 d−1 for MTDW with the contents of content of protein, carbohydrate, and lipid at 49.6 ± 1.4%, 26.1 ± 0.6%, and 10.4 ± 1.8%, respectively. The removal efficiencies of TN, TP, and COD were 80, 94, and 72.24% in MTDW, respectively. In addition, removal efficiencies of 100, 85.37, and 42.86% for Ca2+, Mg2+, and Mo2− were achieved, respectively. The study added to our growing knowledge on the cultivation of Chlorella with wastewater, suggesting that it was feasible to cultivate Chlorella with MTDW and represented an economical and environmentally friendly strategy for microalgae biomass production and reuse of wastewater resources.
