Authors: Md Radzi Nurqameela , Alauddin Kartina , Mohd Derus Mohmad
Published: February 2022

The risk should be managed crucially by any level of multidiscipline. Construction activities involved hazardous situations and unpredictable incidents during construction. There is a central issue triggered by sub-contractors’ tasks, i.e., failure to manage the risk management of main contractors effectively. Many factors contributed to the ineffectiveness of risk management implementation among sub-contractors, including lack of skills and expertise, lack of experience, and communication breakdown with the team. Therefore, this paper significantly provides the results of a survey of sub-contractors involved in the Northern construction projects. The goal of this study concerns the strategies to improve the effectiveness of sub-contractors in managing the risk on site. These are described with the results of the questionnaire survey analysis from 300 respondents. The respondents are from sub-contractors among G1 to G4 in the northern state of East Malaysia. Using the Kruskal-Wallis test, sixteen strategies were identified from the literature have been tested among the sub-contractors. The finding reveals that only ten approaches, i.e., effective site management and supervision, experience contractors, good feasibility studies, project understanding, thoroughly investigate vendor capabilities, frequent progress meetings, systematic coordination between parties, allocation enough resources, the right path, and proper identification of risk does give significant strategies to improve implementation of risk management among sub-contractors in the northern states of Malaysia.Keywords: Risk Management, Sub-Contractors, Strategies, Effectiveness, Construction

Published: February 2022

Construction is a diverse and complex sector. It consists of projects with intricate activities and interfaces between stakeholders who undergo a series of development phases using numerous resources, integration of technologies, materials, and approaches. Theoretically, construction projects can be well planned. However, it is being exposed to unanticipated events or crises that could disrupt original plans, affecting organizations’ operation and progress of construction projects. Problems may even have the propensity to destroy the organization significantly. Considering the current paradigm of crisis, the Covid-19 outbreak that emerged in late 2019 has continuously left a lasting impact on the construction industry. As of August 2020, Covid-19 has spread to over 200 countries, and the number has increased beyond 100,000 cases in Malaysia. Regardless of Covid-19 has placed great stress on all aspects worldwide, it led to the closure of most construction businesses, causing contraction towards industry growth to the greatest to extend of -7.9%, the lowest since 1999. In this context, the effort to ensure the preparedness of the construction organizations against crisis has become an issue. Hence, this paper aims to structure a framework that consists of principles and processes which can recover and develop a resilient construction industry. The method used for this study is Systematic Literature Review of related journals gathered through WOS, ScienceDirect, and Google Scholar, reports, and relevant references from Government Authorised agencies circa 1998 to 2020. 4262 articles were identified, and 111 papers were subsequently selected for further analysis. Based on the findings, there are five major phases of CM, including prepare, prevent, respond, evaluate, and redesign. The proposed CM includes 4 elements and 2 outputs. The preliminary findings form the foundation for an extended investigation to offer a specific crisis management plan to guide the Malaysian construction industry, specifically in Klang Valley, to be resilient during plight.Keywords: Crisis, External Crisis, Crisis Management Plan, Construction Sector

QUALITY ENHANCEMENT OF TOMATOES (Lycopersicum esculentum Mill.) USING GIBBERELLIC ACID (GA) FROM VARIOUS PLANT MATERIALS
Authors: Mayadewi Ni Nyoman Ari , Astawa Nyoman Gede
Published: February 2022

Tomato (Lycopersicum esculentum Mill.) is a fruit with many benefits. Plant growth regulators (PGRs) prove effective in improving the quality and production of tomatoes. Gibberellic Acid/GA is a PGR that stimulates the process of flowering, parthenocarpy, and carbohydrate mobilization during germination and influences other plant physiological aspects. However, because synthetic GA is costly, numerous natural ingredients have been proposed as its source, for example, bamboo shoots, vegetable ferns, corns, and shallots that can improve the quality of tomatoes. This study aimed to determine the role of natural GA from various plant extracts on the quality of tomatoes, providing recommendations for the best extract to improve the quality of tomatoes. It was conducted in the experimental garden at the Agronomy and Horticulture Laboratory, Physiology Laboratory of the Faculty of Agriculture, and Food Analysis Laboratory of the Faculty of Agricultural Technology, Udayana University. This research was compiled using a Randomized Group Design consisting of one factor, i.e., the type of natural extract with five settings and four repetitions. The tomato plant treatments were E0 = no extract sprayed, BE = sprayed with bamboo shoot extract, VE = vegetable fern extract, OE = onion extract, and CE = corn extract. The results showed that gibberellins from natural ingredients significantly affected fruit diameter, fruit thickness, and total sugar content of tomatoes. The best tomatoes were obtained by applying onion extract as a source of natural gibberellins.

Published: February 2022

CADTEL software was developed to provide the simplest and most versatile computing resource that a wide range of skilled researchers and designers can use.  In this paper, a development on this program, relying  on sixteen mathematical models, produced  a new version of CADTEL software package  which focuses on the optimum conditions of Scherzer imaging for round electron magnetic lenses.. These models depend on synthesis procedure which is mainly designed to work with the inverse design problem, and represent the axial magnetic flux density of desirable electron magnetic lens which can be proposed or selected ,  using the four (zero, low, high, infinite) magnification states.  The program provides the freedom of selecting multiple models and changing its variables (which  appear  on the home page), in addition to providing  facilities for numerous  proposed magnetic lens.  The objective properties  calculated in the program were used to compute and plot the optimum conditions  for Scherzer imaging

The CADTEL software  was written in Visual Basic – 6,  in an easy-to-use mode, even for a beginner computer user.   The results of the analysis clearly show that there is an excellent equivalent calculation which could be obtained for the same lens from CADTEL software when evaluated with other counterpart software.

Heavy metals pollution has been a great concern generally due to their toxicity and persistence in environment. This study evaluated the level of pollution and health risks of heavy metals in surface irrigation water used for vegetable cultivation and sediment from Nimo vegetable farm. Three samples each from three different sampling points for water and sediment were collected in dry and rainy seasons and analyzed for Pb, Cd, Mn, Fe, Zn, Cu and Ni concentrations using Atomic Absorption Spectrophotometer. The result showed that heavy metal concentrations in the irrigation water ranged from 0.004 to 0.147 mg/l, 0.119 to 0.773 mg/l, 0.014 to 1.644 mg/l, 0.006 to 0.056 mg/l, 0.009 to 0.576 mg/l, 0.040 to 0.181 mg/l, 0.082 to 0.147 mg/l, for Cd, Pb, Fe, Cu, Zn, Mn, and Ni respectively for the different seasons. In sediment, Cu had the lowest mean concentrations of 0.02±0.01 mg/l while iron had the highest mean concentrations of 6.86±3.06 mg/l. The obtained results were compared with Food and Agriculture Organization and the Department of Petroleum Resources standards for surface irrigation water and sediment respectively. The heavy metal distribution in water was Fe > Pb > Mn > Cd > Ni > Cu = Zn in dry and Zn > Fe > Pb > Ni > Mn > Cu > Cd rainy seasons respectively. Overall, the heavy metals level in the water and sediment were low when compared to the standards. Computed contamination factors and pollution load index showed that the sediment were not polluted while in water, only Cu, Zn, Mn and Fe (in rainy season) showed low contamination, while Ni, Pb and Cd had moderate to very high contamination in both seasons. Hazard Index values for the heavy metals in adults and children via the water and sediment of this study is less than one (HI < 1). Hence the water and sediment from this site poses no health risk to the public. Correlation analysis for metals in water and sediment showed significant and positive relationships amongst the metals which indicated that the most of the metals originate from the same source while few originate from mixed sources mainly from agricultural activities, atmospheric deposition and runoff into the irrigation water.

Ayrıca kolektif etkinlik ve katılımcılık duygusunun ekip performansına etkisinde, karar kalitesinin kısmi aracılık etkisinin olduğu görülmüştür. Yine bu çalışmada kolektif etkinlik ve katılımcılığın ekip karar kalitesine etkisinde ve karar kalitesinin de ekip performansına etkisinde, yüksek rekabetin düzenleyici bir rolünün olduğu bulgularına ulaşılmıştır. Bu çalışmanın sonuçlarına göre; ekipteki kolektif etkinlik ve katılımcılık duygusu artıkça, ekibin karar kalitesi artmakta ve ekipteki karar kalitesi arttıkça da ekip performansı artmaktadır. Ayrıca ekipte rekabet duygusu yüksek ise kolektif etkinliğin ekip karar kalitesine pozitif etkisi, negatif yöne dönüşmektedir. Yani yüksek rekabetin olduğu ekiplerde kolektif etkinlik, ekibin karar kalitesini düşürmekte ve dolayısıyla ekip performansı da düşmektedir.

The use of Proximity Mobile Payment (PMP) applications with several advantages over traditional payment methods is becoming more common. While a large diffusion of PMP is already apparent in South Korea, Germany is still lagging behind. The study examines the acceptance factors regarding the intention to use PMP in the mentioned countries to understand this divergence. A research model was developed to explain the behavioral intention, with an extensive literature analysis. An online survey was conducted, 186 Germans and 146 South Koreans participated the research. Results show that in both countries perceived usefulness, perceived risk, perceived compatibility, and personal innovativeness are the factors that determine the individuals’ intention to use PMP. In addition, the social influence has an impact on the intention only in Germany, while the factors perceived ease of use and trust had no influence in both countries. Lastly, the influence of factors perceived compatibility and social influence on intention varies due to cultural differences. The study provides theoretical and managerial implications as well as an insight for further research.

The aim of present work is to study genetic diversity and phylogenetic relationship among 13 guar varieties from different germplasm conservation centers of India. A total of 64 primer combinations were tested and 24 primer combinations producing best DNA fingerprints were selected for final analysis. The AFLP marker gives keen amplification with 1,671 polymorphic bands and 62 unique bands ranging from 55 bp to 350 bp. Maximum numbers of unique bands were produced with E-ACT/M-CAG primer combination. This analysis allows determining association with an undefined feature and helps in identification of these genotypes. The phylogenetic relationship was explained by a dendrogram generated with UPGMA method. These guar genotypes may be used to develop new varieties with significant improvement in quality and quantity of gum.
Thrombotic Calcified Aneurysm: Importance of Multimodality Imaging

Published: February 2022

Ventricular aneurysms and pseudoaneurysms are one of the most important complications in terms of morbidity and mortality in the spectrum of ischaemic heart disease. Differentiation between them is mandatory, as this will determine the therapeutic approach, ranging from conservative management to emergency surgery. Multimodal imaging, especially CT (Computed Tomography) and MRI (Magnetic Resonance Imaging), plays a key role in this scenario. We present the case of a 60-year-old patient with clinical symptoms of heart failure and chronic occlusion of the right coronary artery with an echocardiographic image suggestive of calcified inferoseptal aneurysm. This finding was confirmed by CT, also showing a filling defect inside the aneurysm suggestive of thrombus; the possibility of pseudoaneurysm could not be ruled out (Figure 1, arrow). To make a differential diagnosis with this entity, an MRI was performed which confirmed the diagnosis of true ventricular aneurysm, intensely calcified, with thrombotic material inside (Figure 2, arrow).

Background: Dyspnea can be seen in COVID-19, and also other conditions including heart failure and this can make a diagnostic challenge. Case Presentation: A 60-year-old man was presented with progressive dyspnea. Chest CT scan showed bilateral opacities, and he was admitted in COVID-specific ward. His dyspnea was worsened and oxygen saturation was reduced. Electrocardiogram showed T wave inversion in precordial leads, and troponin I was positive. Symptoms were improved with loop diuretic therapy and SARS-CoV-2 PCR was negative. Conclusion: COVID-19 is not necessarily the underlying cause of dyspnea in all patients referring to the hospital with respiratory symptoms during this pandemic, and cardiac etiologies are still important.

A 62-year-old male went to the emergency room presenting precordial pain. His electrocardiogram (EKG) showed sinus rhythm at 63bpm, with biphasic T waves, with initial positivity and terminal negativity in leads V2 and V3, and deeply and symmetrical inverted T waves in leads V4, V5 and V6 (Figure 1). A Wellens type A pattern was identified compatible with acute myocardial ischemia. The emergent coronary angiography revealed sub occlusive lesion of the left anterior descending artery (LAD) in the proximal portion (Figure 2). The Wellens syndrome represents an electrocardiographic pattern compatible with acute coronary syndrome.

Background: Reports concerning the clinical usefulness 18F-FDG PET-CT for patients with gallbladder cancer are relatively scarce. The purpose of this study was to assess the diagnostic value of 18FGD- PET-CT in relation to a conventional imaging modality, multidetector row CT (MDCT), for patients with gallbladder cancer. Materials and Methods: Seventy patients with suspected gallbladder cancer who underwent both PET-CT and MDCT for initial staging were included in our study. The results of these two imaging modalities for evaluating primary tumors, regional lymph nodes and distant metastases were compared with the final diagnoses based on histopathological examination. Change in management of patients with gallbladder cancer based on PET-CT was also evaluated. Results: A maximum standardized uptake value (SUVmax) of 5.37 was taken as cutoff value for detecting a malignant tumor. PET-CT demonstrated no significant advantage over MDCT for the diagnosis of a primary tumor. PETCT showed a significantly higher accuracy (90.8 vs. 80.0%, P = 0.04) than that found for MDCT in the diagnosis of regional lymph node metastasis. PET-CT showed higher sensitivity (92.3 vs. 61.5%, P = 0.04) than that found for MDCT in the diagnosis of distant metastasis. Addition of PET-CT in preoperative staging of the disease changed management in 10 patients (14.3%). Conclusions: In patients with gallbladder carcinoma, the addition of 18FDG-PET-CT to standard staging CT may be helpful in detecting distant nodal metastasis and unsuspected metastatic disease that may preclude patients from surgical resection and result in a change of management in a significant number of patients.

We report a dataset of 96,962 new crystal structures discovered and computed using our previously published autonomous, density functional theory (DFT) based, active-learning workflow named CAMD (Computational Autonomy for Materials Discovery). Of these, 931 are within 1 meV/atom of the convex hull and 27,075 are within 200 meV/atom of the convex hull. The dataset contains DFT-optimized pymatgen crystal structure objects, DFT-computed formation energies and phase stability calculations from the convex hull. It contains a variety of spacegroups and symmetries derived from crystal prototypes derived from known experimental compounds, and was generated from active learning campaigns of various chemical systems. This dataset can be used to benchmark future active-learning or generative efforts for structure prediction, to seed new efforts of experimental crystal structure discovery, or to construct new models of structure-property relationships.
