Authors: Reymond Reflon F Gultom  , Sabri Muhammad
Published: March 2022

Pengelasan adalah proses penyambungan logam atau non-logam yang dilakukan dengan memanaskan material yang akan disambung hingga temperatur las, yang dilakukan dengan atau tanpa menggunakan tekanan dan dengan atau tanpa menggunakan logam pengisi. Salah satu teknik pengelasan adalah dengan pengelasan SMAW (Shield Metal Arc Welding) dan GTAW (Gas Tungsen Arc Welding). Dengan las tersebut kita dapat menyambung logam seperti: Aluminium, Tembaga, Carbon Steel, dan Stainless Steel. Penelitian ini dilakukan untuk mengetahui sifat mekanik, struktur mikro, dan kekuatan sambungan las pada Baja AISI 1050. Pengelasan dilakukan dengan menggunakan tungsten TG-S50 untuk las GTAW dan elektroda E-6013 untuk las SMAW pada arus 100 Ampere dengan sambungan kampuh V 60o. Metode pengujian yang dilakukan adalah uji kekerasan dengan metode Brinell Hardness Tester, uji tarik dengan Tensile Tester, dan uji struktur mikro dengan Metallurgycal Microscope. Hasil rata-rata dari uji kekerasan Brinell didapat sifat mekanik baja AISI 1045 las SMAW pada daerah las dengan elektroda E-6013 pada arus 100 A adalah 160,04 BHN dan las GTAW dengan filer TG-S50 pada arus 100 A adalah 172,53 BHN. Nilai rata-rata tegangan las SMAW dengan elektroda E-6013 pada arus 100 A adalah 323,14 MPa dan las GTAW dengan filler TG-S50 pada arus 100 A adalah 411,57 MPa. Bentuk struktur mikro pada daerah lasan dengan pengelasan GTAW memiliki struktur mikro yang lebih kecil dibandingkan dengan pengelasan SMAW, hal ini membuktikan bahwa nilai kekerasan pada daerah lasan GTAW lebih besar dari pada nilai kekerasan pada daerah lasan SMAW.

Published: March 2022

The popularity of moving abroad for working and travelling at the same time has started to become a lifestyle that gradually breaks the traditional way of working as salaried workers or being known as a Digital Nomad (Müller, 2016). In Thailand, Bangkok, Chiang Mai and Phuket are the top destinations, especially Chiang Mai, which was once chosen as the world's number 1 destination for digital nomads to move to (Chiangmai buddy, 2017). This study aims to understand the factors of nomads’ migration (Pofeldt, 2017). Qualitative research collected data and in-depth interviews with 11 key informants through a digital nomad community in Chiang Mai. Data analysis was performed through the method of content analysis. The results of the research showed that there were three factors supporting a decision of selecting Chiang Mai as a destination city. The first factor is natural and cultural capital, such as its unique culture, various tourist attractions, food, and diverse nature. The second factor is access to work and communication infrastructures through the internet, cafés, internet prices, and services. The third factor is information exchange networks are built, integrating networks of a digital nomad community in Chiang Mai where opinions are exchanged, and activities are performed constantly. This has led to exchange networks that have made Chiang Mai become a top destination for nomads around the world.

Published: March 2022

In this study, the improvement of mechanical properties and crack healing as a result of the calcium carbonate precipitation due to bacterial activity have been investigated in two phases. First, the optimum mix design of self-healing cement mortar has been achieved considering different amounts and concentrations of the bacterial solution of bacterium Sporosarcina pasteurii (ATCC 11859) in non-pre-cracked specimens. Some of the mechanical properties, such as compressive strength, flexural strength, energy absorption capability, and weight change in bacteria added cement mortar specimens are compared with those of control specimens. Second, using the determined optimum mix design, mechanical properties of self-healing cement mortar specimens with initial cracks are compared with those of non-pre-cracked specimens to evaluate the recovery degree. 28-day compressive and flexural strengths of cement mortar specimens through direct addition of bacterial suspension with a concentration of 5.1 × 107 cells/ml improved by 45% and 18%, respectively. These results for 7-day specimens were 78% and 24%, respectively. Experimental flexural strengths of pre-cracked specimens are higher than their theoretical values based on the reduced cross-sections, and in pre-cracks with smaller dimensions, higher recovery degrees are achieved.

HYBRID THREATS AND THE DEVELOPMENT OF THE NEW NATO OVERARCHING CONCEPT
Authors: SPISAK JAN
Published: March 2022

This article deals with aspects of newly emerging security challenges that military theoreticians and authors of security and defense strategic documents name ‘Hybrid Threats’. They currently present a significant challenge for the Alliance and its interests. Hybrid Threats involve adversaries (including states, rogue states, non-state actors or terrorist organizations) that may employ a combination of actions in an increasingly unconstrained operating environment in order to achieve their aims. Hybrid Threats may consist of a combination of every aspect of warfare and compound the activities of multiple adversaries. Experience from current operations has demonstrated that adversaries can now conduct hostile actions through a broad array of conventional or non-conventional means, methods and procedures, having a favorable outcome against a NATO force that is technologically and militarily superior. Cognition of the scale and complexity of future threats has demanded a development of an overarching Capstone Concept1 for the NATO Military Contribution to Countering Hybrid Threats (MCCHT). This Concept articulates the unique challenges posed by current and future Hybrid Threats and explains why these challenges may require NATO to adapt its strategy, structure and capabilities for the next twenty years.
Survival of Non-Small Cell Lung Cancer Patients with Unexpected N2 after Complete Resection: Role of Aggressive Invasive Mediastinal Staging should be Considered
Authors: Geanphun Suparauk , Rerkpichaisuth Vilasinee , Ruangchira-urai Ruchira , Thongcharoen Punnarerk
Published: March 2022

Objective: Mediastinal lymph node (N2) metastasis is one of the poor prognostic factors in non-small cell lung cancer patients (NSCLC). However, the accuracy of mediastinal lymph node staging in real practice is uncertain and inadequate. Consequently, the aim of this study was to determine the survival of NSCLC patients with clinically non-suspicious mediastinal lymph node metastases who underwent complete resection but were pathologically confirmed as having N2 metastases (unexpected N2).Materials and Methods: A retrospective review was performed of all pathology-proven N2 metastases NSCLC patients who underwent curative surgical resection from January 2007 to December 2016. A total of 158 patients were initially included in the study. After the exclusions (known N2, small cell carcinomas, neuroendocrine tumor), 125 unexpected N2 patients who underwent complete resection were analyzed. Survival analysis was determined using the Kaplan–Meier method and multivariate analysis was determined using the Cox regression method.Results: The overall 2-year, 3-year, and 5-year survival rates were 40%, 24%, and 20% respectively. Complete resection was achieved in all patients. Invasive mediastinal staging (IMS) was performed in 47 patients (37.6%), by endobronchial ultrasonography (EBUS) in 46 (36.8%) patients (82.6% negative and 17.4% inadequate tissue) while only 1 patient underwent mediastinoscopy. The factors affecting the survival rate upon comparison were the histology type (p=0.019), differentiate characteristics (p=0.004), adjuvant therapy (p=0.011), and presence of distant metastasis by postoperative re-staging (p=0.003). The independent predictive factors for survival werechemo-radiation therapy (odds ratio 0.367, 95% confidence interval 0.176–0.766) and distant metastasis (odds ratio 2.280, 95% confidence interval 1.334–3.897). However, a small size, periphery lesion, T staging, and number of N2 lesions were not significant factors.Conclusion: The survival rate of unexpected N2 patients was low despite complete resection being achieved in these patients. Adjuvant therapy seemed to improve survival for those with unexpected N2 metastasis as it is a systemic disease. However, not all patients received IMS, which was mostly done by EBUS and which had a high false negative, leading to underestimating the staging. Other modalities, such as cervical mediastinoscopy, videoassisted mediastinoscopic lymphadenectomy (VAMLA) or open biopsy should be considered for the adequate evaluation of N2 metastasis, nonetheless further study is still needed.

Objective: Airway complications in obese patients are a major concern during surgical operation. This study aimed to determine the incidence of airway- and respiratory-related anesthetic complications for obese (including maternal) patients undergoing general anesthesia.Materials and Methods: This multicenter, retrospective, observational study evaluated obese female patients (BMI≥ 30 kg/m2), both non-pregnant and pregnant, undergoing general anesthesia in 5 hospitals across Thailand during May 2013 - August 2016. The primary observation was anesthesia-related airway complications (difficult and failed intubations, aspiration, desaturation, and airway injuries) detected during anesthesia. An analysis was performed to compare the incidents of the adverse events and to determine the risk factors for airway-related adverse events in both groups.Results: There were 1,347 obese patients enrolled (777 non-pregnant and 570 pregnant). The overall incidence of airway and respiratory complications was observed in 129 patients (9.6%), with a higher rate in pregnant patients (12.5% vs. 7.5%; p<0.05). The most common complications were desaturation (5.6%) followed by airway injuries (3.6%) and difficult intubation (1.5%). The factors significantly associated with adverse airway-related events were obesity class II (OR=1.63 [1.05–2.54]), obesity class III (OR=2.25 [1.19–4.25]), pregnancy (OR=1.73 [1.18–2.54]), Mallampati classifications III–IV (OR=1.69 [1.16–2.48]), and neck circumference <43 cm (OR=3.33 [1.02-10.81]), p<0.05).Conclusion: The incidence of the anesthesia-related airway and respiratory complications was 9.6%, with a higher rate in pregnant patients. The most common adverse airway event was desaturation. However, the frequency of serious airway events was low.
Application of Nanotechnology in Insect Pest Management: A Review
Authors: Zannat R , Rahman MM , Afroz M
Published: March 2022

Insect pests are one of the most concerned biotic obstacles in agriculture and humans are constantly in search of new strategies to control them. Chemical pesticides are extensively used for controlling insect pests which cause a lot of problem, such as pest resistance, elimination of natural enemies, environmental pollution, loss of biodiversity and human health hazards. As an alternative pest control strategy, the application of nanotechnology in insect pest management can be one of the most promising ways to overcome the problems related to the application of conventional chemical pesticide. According to various research findings, the nano based materials are described as very effective in insect pest management because they have larger surface area which ensures the contact of more volume of pesticides with the insect pests. They also provide selective, targeted and long term-controlled release of formulation of nanomaterial which is ecologically more viable. Moreover, the required amount of nano-insecticide is also very small for controlling insect and thus the pesticide load in the environment gets reduced. So, use of nanotechnology for insect pest management is considered as environmentally sustainable and a brilliant insect control strategy in green agriculture.

Published: March 2022

Assessment of thirty-six similar named aromatic rice landraces of Bangladesh was analyzed using 36 microsatellite markers to characterize the landraces and also to establish the sovereignty of the Bangladeshi rice gene pool. With an average of 3.03 per locus, overall 109 alleles differed from 2 to 5 were detected at 36 microsatellite loci across the 36 aromatic rice landraces. With an average of 0.48, the diversity of genes ranged from 0.15 to 0.74. The polymorphic information content (PIC) values ranged from 0.14 (RM500, RM554) to 0.69 (RM496), with an average of 0.41, revealed many variations among the studied landraces. The recurrence of the most prevalent allele at each locus ranged from 31.00% (RM496) to 96.00% (RM500 and RM554). At any given locus, on average 64.33% landraces out of 36 contributed a familiar major allele. For identification and diversity estimation of aromatic rice landraces, RM496 was the finest marker as affirmed by PIC values. Two clusters were revealed with a similarity coefficient of 0.45 by a UPGMA dendrogram in SSR. All the landraces were also divided into two groups (A and B) through the model-based clustering method, confirmed by UPGMA cluster analysis. Some of the SSR markers (RM1, RM489, RM39, RM474, RM2, RM214, RM21, and RM206) generated unique alleles that were specific to particular landraces and were useful for varietal identification. Besides, the evaluation of genotypic data demonstrated the landraces under this study provided noticeable genetic diversity.
