Problems in Insuring Maintenance of Transport Systems of Fluid Hydrocarbons Through Metal Pipes
Authors: Vlădescu Robert-Gheorghe
Published: February 2022

The structural continuity of the and the integrity of the metallic materials specific of pipelines guarantees their exploitation under proper technical conditions and with the minimum reduction of environmental risks, representing a permanent preoccupation and essential condition in the maintenance of the transport systems of fluid hydrocarbons through metallic pipes.

Metallic and non-metallic materials coming in contact with a certain environment suffer gradual degradation due to reciprocal interaction.

The nature of this interaction can be chemical or electrochemical and this, in time, makes the material unusable due to the structural, dimensional or continuity changes.

The resistance to corrosion of a metallic material is closely related to the composition and its structure, to its degree of purity, to the nature and characteristic of the corrosive environment, to the conditions in which the corrosion takes place.

When there is uniform corrosion, the behavior of the material is evaluated by the gravimetric index, the penetration index and the volumetric index.

The protection against corrosion represents the total measures taken to diminish the destructive action of the environment on materials in working concrete conditions, at the lowest possible cost and by meeting safety conditions.

The main means of protection or reduction of the corrosion intensity are the following: treatment of the environment (with the purpose of reducing its aggressivity), coating of the surfaces exposed to the corrosion, application of surface treatments, moving the electrochemical potential of the metal in the field of immunity or passaging and draining of dispersion currents.

The displacement of the potential of the metallic material protected in the field of immunity can be ensured by the realization of a galvanic pile with an active anode or by current injection, which opens, as an engineering practice, the way to ensuring the cathodic protection applied to the equipments in contact with an electrolyte (water, oil etc.), as the most modern method of preventing the loss of metallic material and of structural damage of the pipes destined for the transport of fluid hydrocarbons.

Authors: Roman Mihai-Vasile , Popescu Daniela
Published: February 2022

To comply with latest standards regarding emission regulations, diesel technology focuses on how to obtain a very good spray quality, by identifying the appropriate geometry for injector nozzles, the optimum size of injection holes and the best hydraulic parameters for efficient fuel spray evolution and dispersion. In practice, injectors are often subject to operating problems, mainly because inside the diesel fuel injector nozzle, accumulation of deposits might occur. To control the phenomenon, the scientific literature proposes anti-corrosion treatment. The present paper studies the effect of applying anti-corrosion treatment to a new diesel injector. The investigation method consists in using a Scanning Electron Microscope next to EDX Spectrometry. The results indicate that chemical treatment can lead to new deposits that also contaminate the nozzles. Concluding, the anticorrosion treatment must include monitoring and control of the process and as a final step, a method to remove detergent deposits.

Authors: Iorgoaia Daniela Gabriela Ciobanu
Published: February 2022

Electrochemical machining relies on the electrolysis phenomenon, this being characterized by the chemical reaction between the workpiece material and an electrolyte solution. Both the electrode and the workpiece materials are connected into an electric circuit, charged by a direct current electric energy source. The workpiece is used to get some complex forms of cavities into parts of electrically conductive materials or other hard conductive materials, which could not be processed efficiently by the other means. This paper presents the results of some research related to the development of an equipment concept that could highlight the variation of some output parameters of the process in function of the value of the input factors in the process. It has opted to create a device for studying electrochemical erosion, where different substances, with a direct current source with variable adjustment. Taking into account the experimental results when using different materials for the workpiece, different materials for the tool electrode, many working electrolyte type substances, and changing the values of the electrical parameters, results necessary for a relevant conclusion could be obtained.

Authors: Nan Zhang , Zhimin Lv , Shen Qiao , Ting Li
Published: February 2022

Bat algorithm is an effective swarm intelligence optimization algorithm which is widely used to solve continuous optimization problems. But it still has some limitations in search process and can’t solve discrete optimization problems directly. Therefore, this paper introduces an unordered pair and proposes an unordered pair bat algorithm (UPBA) to make it more suitable for solving symmetric discrete traveling salesman problems. To verify the effectiveness of this method, the algorithm has been tested on 23 symmetric benchmarks and compared its performance with other algorithms. The results have shown that the proposed UPBA outperforms all the other alternatives significantly in most cases.

Published: February 2022

There has been an amplified focus on and benefit from the adoption of artificial intelligence (AI) in medical imaging applications. However, deep learning approaches involve training with massive amounts of annotated data in order to guarantee generalization and achieve high accuracies. Gathering and annotating large sets of training images require expertise which is both expensive and time-consuming, especially in the medical field. Furthermore, in health care systems where mistakes can have catastrophic consequences, there is a general mistrust in the black-box aspect of AI models. In this work, we focus on improving the performance of medical imaging applications when limited data is available while focusing on the interpretability aspect of the proposed AI model. This is achieved by employing a novel transfer learning framework, progressive transfer learning, an automated annotation technique and a correlation analysis experiment on the learned representations.

Progressive transfer learning helps jump-start the training of deep neural networks while improving the performance by gradually transferring knowledge from two source tasks into the target task. It is empirically tested on the wrist fracture detection application by first training a general radiology network RadiNet and using its weights to initialize RadiNetwrist
, that is trained on wrist images to detect fractures. Experiments show that RadiNetwrist
achieves an accuracy of 87% and an AUC ROC of 94% as opposed to 83% and 92% when it is pre-trained on the ImageNet dataset.

This improvement in performance is investigated within an explainable AI framework. More concretely, the learned deep representations of RadiNetwrist
are compared to those learned by the baseline model by conducting a correlation analysis experiment. The results show that, when transfer learning is gradually applied, some features are learned earlier in the network. Moreover, the deep layers in the progressive transfer learning framework are shown to encode features that are not encountered when traditional transfer learning techniques are applied.

In addition to the empirical results, a clinical study is conducted and the performance of RadiNetwrist
is compared to that of an expert radiologist. We found that RadiNetwrist
exhibited similar performance to that of radiologists with more than 20 years of experience.

This motivates follow-up research to train on more data to feasibly surpass radiologists’ performance, and investigate the interpretability of AI models in the healthcare domain where the decision-making process needs to be credible and transparent.

Paparan kebisingan yang terus menerus di tempat kerja tanpa ada upaya atau tindakan pencegahan apa pun dapat menyebabkan gangguan non-auditory. Gangguan non-auditory meliputi tiga aspek yaitu, gangguan fisiologis, gangguan psikologis, dan gangguan komunikasi. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang berhubungan dengan gangguan non-auditory pada pekerja spinning di PT. Unitex Bogor. Jenis penelitian ini merupakan penelitian kuantitatif dengan desain studi Cross Sectional, menggunakan teknik Quota Sampling sebanyak 52 responden. Pengumpulan data dilakukan dengan menggunakan kuesioner. Penelitian ini dilaksanakan pada pada bulan November tahun 2020 sampai September tahun 2021.  Sebanyak 75% responden memiliki keluhan gangguan non-auditory, 90,4% jenis kelamin laki-laki, 82,7% usia tua, 53,8% masa kerja lama, 55,8% tidak memenuhi NAB, 65,4% pemakaian APT tidak patuh, 61,5% pengetahuan kurang baik, 40,4% sikap negatif. Hasil uji chi-square menunjukkan terdapat hubungan usia, masa kerja, intensitas kebisingan, pemakaian APT, pengetahuan, sikap dengan gangguan non-auditory. Sedangkan, variabel jenis kelamin tidak memiliki hubungan dengan gangguan non-auditory. Diharapkan pekerja perlu diberi pelatihan pengetahuan terkait dampak yang akan timbul dari kebisingan jika tidak menggunakan APT, agar pekerja menjadi paham apa akibat dari terpapar kebisingan jika tidak menggunakan APT saat bekerja.

The present work was undertaken to develop a reproducible protocol for the micropropagation of an important medicinal plant of the Cucurbitaceae family, Coccinia cordifolia (L.) Cogn., by using shoot tips and nodal segments to overcome the impediment in seed settings and seed germination of conventional reproduction. To develop an efficient protocol, 0.1% HgCl2 treatment for 6 minutes was found effective for surface sterilization of field-grown explants to eliminate microbes and fungus and to get healthy tissues. Throughout the study, different concentrations of auxin, cytokine, and gibberellin were used either alone or in combination as supplemented in MS medium to find suitable conditions and suitable explant (nodal segment). BAP was the best cytokine source as 2.0 mg/l BAP produced 4.0±0.20 and 4.8±0.09 shoots per culture and gained 5.8±0.11 cm and 6.7±0.32 cm length with regeneration rate of 90 and 100 percent in shoot tips and node, respectively. The highest percentage (90%) of regeneration for axillary shoot proliferation was obtained in node explants at MS medium containing 2.0 mg/l BAP + 0.1 mg/l NAA. The highest number of shoots regenerated per culture was 3.0±0.41, with a length of 6.0±0.16 cm. GA3 was also found effective in producing longer shoots with the combination of BAP, but the average shoot number was reduced drastically. Although full-strength MS medium was found to be ideal for shoot regeneration and used in shoots proliferated experiments, half and full-strength of MS medium with auxins supplements of 0.5, 1.0, and 2.0 mg/l either of IBA, NAA, and IAA) were used for roots growth and half strength nutrients supplemented with 0.5 mg/l IBA was found most compelling. The highest number of roots regenerated per shoot was 3.1±0.30, and the average root length was 1.8±0.30 cm. Rooted plantlets were finally transplanted into small plastic pots containing sun sterilized sand, soil and humus (1: 2: 1) to adapt the plantlet in ex vitro environment, and acclimatized plantlets showed 95% survival rate in outdoor condition which proved the effectiveness of using biotechnology to improve plant’s growth rate and mass production.

Basal stem rot caused by Ganoderma boninense is a major disease of oil palm in Indonesia. Environmental factors associated with disease can be used as the basis for developing disease control. This study aims to describe the physical and chemical properties of oil palm plantations land mineral soil land that is infested with basal stem rot. Soil composite samples were randomly collected from diseased and healthy palm circle from an oil palm plantation in Mesuji, South Sumatra. The results showed that the texture and nutrient status of diseased and healthy plants were not significantly different, namely they had the same low analytical values ​​in terms of the content of N, C-organic, CEC, Mg, Ca, Na, and K2O. The ratios of C/N, exchangeable K and exchangeable acidity in healthy and diseased soils were both moderate to high. The content of available P and total P was very high (43−134 ppm) and was found to be higher in the soil of diseased plants than in healthy plants. These results indicated that high availability of P nutrients may favor G. boninense infection in oil palm plantation.

The relevance of capital structure decision in the banking sector is documented in this paper. It contributes to existing literature in a review of previous empirical studies and fundamental theories of capital structure. The study underscored the factors influencing the choice of funding in connection with the market timing theories such as Pecking Order theory and the trade -of - theory. Our investigation suggest that, the choice of capital vary across sectors and industries on the basis of business risks, corporate governance, profitability, internal controls, and efficiency. The study observed that most empirical researchers universally endorsed asset structure, industry volatility, corporate taxes and firm growth as strong determinants of capital structure. The above issues may either improve the solvency position of a form or trigger major financial distress depending on the source of capital.

This study aims to determine the effect of corporate social responsibility, enterprise risk management, and the characteristics of the board of directors on value relevance. The characteristics of the board of directors are broken down into two more variables, namely the proportion of female directors and the education level of the CEO. The value relevance proxy are measured by combining the ratio of price book value and earnings per share. The sample was selected using a purposive sampling method, which resulted in 40 companies in the consumer goods industry included in the Indonesia Stock Exchange for the period 2017-2020. This study uses multiple linear regression analysis which is processed using SPSS 23. The results of the analysis show that the corporate social responsibility variable, the proportion of female director and the CEO's education level have a positive influence on value relevance while the enterprise risk management variable has no effect on value relevance.

This study examines the effect of education and mass media on discriminatory attitudes towards people living with HIV (PLHIV) among women in Nepal. Data were drawn from the Nepal Demographic and Health Surveys 2006, 2011, and 2016 and covered 36,329 women of reproductive age (WRA) 15–49 years. An example of discriminatory attitude towards PLHIV is not wanting to buy fresh vegetables from a shopkeeper or vendor if an individual knew that the seller had HIV. Discriminatory attitude toward PLHIV has increased significantly over time (27.3% in 2006 to 29.7% in 2011 and 34.2% in 2016) among the WRA. Women who had no education and only primary education were 23% (aOR = 1.23, 95% CI 1.13–1.34) and 46% (aOR = 1.46, 95% CI 1.35–1.58) more likely to be affected by discriminatory attitudes, respectively, than those who had secondary or above education. Similarly, women who did not read newspapers were about five times more likely (aOR = 4.91, 95% CI 2.65–9.10) to develop a discriminatory attitude towards PLHIV than those who read newspapers almost every day. A similar trend was observed in exposure to television as well. This study illuminated the significance of women’s education and media exposure in minimizing the discriminatory attitude towards PLHIV. A new intervention is needed since existing interventions could not reduce the discriminatory attitude towards PLHIV.

This study aims to determine the chronicity of poverty in Indonesia using the equally distributed equivalent (EDE) poverty gap method, tracking Indonesian households in 2007 and 2014. The results indicate that the largest component of poverty among households was chronic (77%). Compared to transient poverty, chronic poverty is more common across individuals. Unlike previous studies, we used data at the district level to measure the poverty line, discovering that the cost of poverty inequality is lower than often reported. This decision is because disaggregated data (poverty line) can show a more realistic poverty threshold. Using a quantile regression approach, we found evidence that age, gender, employment status, and education were significant factors of chronicity. Other significant factors of chronic poverty include large household size, having no access to services (finance, electricity, information, and mobility), and having limited or no assets. Casual employment in the agricultural sector and living in rural areas increase the probability of poverty, although not necessarily chronic. Poverty alleviation programs, therefore, need to target the right causes as exposure to poverty varies across households.

This article is dedicated to the relevant problem – extremism in youth environment. The author summarizes new material on the topic, as well as introduces into the scientific discourse the description of the types of extremist personality among male high school students. The goal is to reveal the traits of extremist personality in high school students, and typologize these manifestations based on the empirical data. The scientific novelty lies in studying the characteristics of extremist personality among male high school students. The two types of personality are determined. It is established that extremist patterns in personality manifest through the following parameters: duty to endure pain and acceptance of the duty to die; propensity to manipulate; tendency to submerge into transcendental and transpersonal; level of satisfaction of basic social needs; degree of psychological stability; level of anxiety; level of identity manifestation, level of tolerance to negative mental states, level of social and communicative tolerance. The author reveals the pronounced psychological characteristics of the two key types of extremist personality among high school students. The first type can be characterized as infantile, immature personality with a severe need for love, acceptance, protection, support, prone to dogmatism and power thinking. The second type has evident autistic features: lack of nee for social relations, fear of the surrounding world, any deviations from the usual, familiar surroundings, and course of life.
