Published: September 2020

Статья посвящена исследованию зависимости жесткости опилок от их фракции и степени уплотнения при прессовании на гидравлическом прессе. Для экспериментов использовали опилки, полученные при пилении древесины сосны дисковой и цепной пилой. Экспериментальный материал предварительно сепарировали при помощи колонки сит так, чтобы получить пробы с различной фракцией: 5-10 мм, 3-5 мм, 2-3 мм, 0,5-2 мм, <0,5 мм (поддон). Влажность опилок составляла 7-10%. Прессование экспериментальных проб производили на гидравлическом прессе RUF BP-600 при давлении прессования до 150 МПа. Всего было выполнено 15 опытных запрессовок, по 3 повторения для каждой фракции опилок. Установлено, что в общем виде экспериментальные зависимости потребного давления прессования опилок от плотности брикетов можно описать степенными функциями. Также на основании экспериментальных данных установлено, что модуль деформации сосновых опилок изменяется в пределах от 0,5 до 5 ГПа и заметно зависит как от плотности, так и от фракции прессуемого материала. Экспериментально установлено, что при равном давлении легче, по сравнению с прочими фракциями, прессуются опилки фракцией 3-5 мм. Оптимальная для прессования фракция опилок в проведенных опытах составила 3,7 мм. При фракции крупнее 7 мм жесткость материала резко возрастает, в связи с этим процесс прессования усложняется. В заключение освещаются перспективные направления дальнейших экспериментальных исследований, приводятся рекомендации по структуре планов последующих экспериментов.
The article focuses on the dependence between stiffness of pine sawdust, its faction and compaction degree in the process of briquetting under hydraulic press. Experimental samples came from sawdust produced with sawing of pine wood with circular saw and a chainsaw. The experimental material was separated using a column of sieves in order to obtain samples of various fractions: 5-10 mm 3-5 mm 2-3 mm, 0.5-2 mm, <0.5 mm (on the pan). The sawdust had 7-10% humidity. Briquetting of the experimental samples was performed with RUF BP-600 hydraulic press at a pressure of 150 MPa. (15 experimental samples total, 3 reps for each sawdust fraction). The results establish that in general the experimental dependence between required compaction pressure and the briquettes density appears as a power functions. Based on experimental data, research sets that the deformation modulus of pine sawdust varies from 0.5 to 5 GPa and significantly depends on the density and fractions of the molded material. The paper establishes that 3-5 mm fraction of sawdust is easier compacted compared to other fractions. Optimal fraction of sawdust in the experiments was 3.7 mm. Sawdust fraction over 7 mm has sharply increased stiffness, thereby pressing process becomes complicated. In conclusion, the article highlights prospective topics for further experimental research, providing guidance on the structure of plans for subsequent experiments.
Evaluation of Serum Ferritin and Anti-Thyroid Peroxidase Antibody Status in Newly Diagnosed Subclinical Cases of Hypothyroidism
Authors: Tiwari Rajlaxmi , Saharia Gautom Kumar , Mangaraj Manaswini 
Published: September 2020

Background:
Serum ferritin concentrations are altered in hypothyroidism, but there is
no available literature regarding the status of serum ferritin in anti-thyroid peroxidase (anti-TPO)
positive hypothyroidism. The objectives of our study were to evaluate the titer of anti-TPO and
serum ferritin in newly diagnosed hypothyroid patients and to find out any difference in serum ferritin
concentration between antibody-positive and antibody-negative patients.

Methods:
A total of 143 subjects above the age of 18 years were recruited, and serum Thyroid Stimulating
Hormone (TSH), free T3, free T4, anti-TPO, and ferritin were assayed by chemiluminescence
method. According to their serum analysis findings, three groups were made as Group 1 of
49 subjects with hypothyroidism and anti-TPO positive, Group 2 of 47 subjects with hypothyroidism
and anti-TPO negative, and Group 3 of 47 euthyroid and anti-TPO negative controls.

Results:
Kruskal Wallis H test was applied, and the difference in concentration of TSH, FT3, FT4,
Ferritin, anti-TPO amongst the three groups was found to be significant. The relationship between
anti-TPO levels and serum ferritin concentration was further studied by multinomial logistic regression.
We have found that there is a significant difference between the concentrations of ferritin;
hence, it is highly likely that those with a high level of anti-TPO antibody shall have a higher concentration
of serum ferritin.

Conclusion:
Ferritin concentrations were decreased in anti-TPO negative hypothyroidism, but in
the case of anti-TPO positive hypothyroidism the ferritin concentrations are raised. Hence, hypothyroidism
should not always be considered as an iron deficiency state.

Published: September 2020

In hemodialysis patients, the prevalence of malnutrition is high; a decrease in muscle strength is observed.
The objective of the research was to evaluate the nutritional status of hemodialysis patients and the relationship between the nutritional status and muscle strength.
Materials and Methods. Sixty hemodialysis patients (38 males, 22 females) were chosen from among volunteers. Food consumption, biochemical values, anthropometric measurements, body composition, physical activity status, subjective global assessment, and handgrip strength in individuals were examined.
Results. According to subjective global assessment, 73.3% of patients were well-nourished, 26.7% of patients were moderately malnourished. In male patients, a moderate positive correlation was determined between handgrip strength and lean body mass (r=0.359, p<0.05), albumin level (r=0.408, p<0.05), energy intake (r=0.437, p<0.05), protein intake (r=0.345, p<0.05). In female patients, a moderate positive correlation was determined between handgrip strength and body weight (r=0.470, p<0.05), body mass index (r=0.472, p<0.05), triceps skinfold thickness (r=0.530, p<0.05), mid-upper arm circumference (r=0.515, p<0.05), mid-upper arm muscle circumference (r=0.557, p<0.05), lean body mass (r=0.470, p<0.05), body fat content (%) (r=0.588, p<0.05), albumin level (r=0.565, p<0.05).
Conclusions. Handgrip strength alongside with more than one method of food consumption, biochemical parameters, subjective global assessment, anthropometric measurements, and body composition should be used for assessing the nutritional status in hemodialysis patients.

Published: September 2020

Diabetes mellitus is referred to as non-communicable epidemic of the 21st century and the fight against diabetes is one of medical and social challenges. One of its complications is damage to periodontal tissues that is accompanied by tooth loss. Any removable denture is a foreign body being a stress factor for the oral cavity.
The objective of the research was to study dynamic changes in the activity of stress factor indicators, namely salivary cortisol, glucose and alpha-amylase levels in diabetic patients after prosthodontic treatment with complete removable laminar dentures.
Materials and Methods. For this study, patients at the age of 45 to 74 years were divided into two groups: Group I included 52 edentulous patients with type 2 diabetes mellitus who were treated with acrylic resin complete removable laminar dentures; Group II comprised 52 edentulous patients without endocrine pathology who were treated with acrylic resin complete removable laminar dentures as well. Saliva served as the study material. The enzyme-linked immunosorbent assay was used to determine salivary cortisol levels. Glucose concentration in saliva was determined by a unified enzymatic method. Alpha-amylase activity was determined by the enzymatic colorimetric method.
Results. According to the research results, before prosthodontic treatment, salivary cortisol levels of patients with diabetes mellitus were 2.4 times higher as compared to patients without somatic pathology. In phase I of adaptation to complete removable laminar dentures, in patients with diabetes mellitus, salivary cortisol concentration increased drastically by 1.4 times as compared to the indicator before prosthodontic treatment (5.61±0.83 ng/ml vs. 4.02±0.65 ng/ml, p<0.01), while in the group of patients without endocrine pathology, cortisol levels increased by 1.2 times; salivary glucose level of patients with diabetes mellitus increased by 1.3 times, while in patients without endocrine pathology, it increased by 1.1 times; in patients of Group I, salivary alpha-amylase levels increased by 1.2 times, while in patients of Group II, salivary alpha-amylase concentration increased by 1.05 times.
Conclusions. In patients with diabetes mellitus, changes in saliva composition indicate a significant reduction in the adaptation mechanisms, that complicates and significantly prolongs the period of adaptation to complete removable laminar dentures.

Published: September 2020

The authors presented the results of laboratory studies of artificial soil based on sand-paraffin mixtures, reflecting the physical and mechanical soil properties with the presence of plant residues. They conducted tests to determine the soil-cutting working bodies’ traction resistance during tillage with the presence of root and crop residues.(Research purpose) To substantiate the parameters of an artificial soil environment containing models of root and crop residues for laboratory studies of the wear and traction characteristics of soil-cutting working bodies operated on post-harvest, virgin and fallow farmland.(Materials and methods) An artificial soil environment was developed by introducing filamentous components 5-25 millimeters long into its composition.(Results and discussion) The authors determined the criteria of geometric similarity “model – nature” for the soil conditions of the Non-Black Earth Zone of Russia. It was found that the equality of the criteria “model – nature” for laboratory research of fallow lands occurred when the length of the filamentous components was from 20 mm and the concentration was from 20 segments per unit cross-sectional area when passing 0.1 meter in artificial soil. It was revealed that for modeling old arable lands, the length of the filamentous components should exceed 5 millimeters, the concentration should be from 10 segments per 0.1 meter of the length of passage in artificial soil. The authors conducted field tests of arable units on fallow and old arable lands.(Conclusions) The authors found out that the equality of the geometric criteria for the similarity of the artificial soil environment and real soil conditions allowed laboratory studies of the wear and traction characteristics of the tillage working bodies’ blades. It was determined that more than 30 percent of energy costs were accounted for by breaking the root system of the vegetation cover on virgin and fallow lands.

Published: September 2020

The aging process of asphalt in the pavement layers of asphalt concrete road occurs when mixing in the Asphalt Mixing Plant and during the road service period. The asphalt aging process when mixing is called short-term aging and aging during the road service period is called long-term aging. AC - WC mixture is a wear layer and it is on the top layer of the surface which allows characteristics change that are influenced by several environmental factors (air, temperature and sunlight). This study aims to know the effect of asphalt aging on the characteristics of AC - WC mixture with Marshall method on some asphalt content that are 4.5%, 5.0%, 5.5%, 6.0%, 6, 5% and 7.0%. For testing on short-term aging (Short - Term Oven Aging, STOA) is by testing the mixture specimen AC - WC at 135o C before solidified for 4 hours and for long-term aging (Long - Term Oven Aging, LTOA) was carried out by testing the mixture specimen AC - WC at 85o C for 2 - 5 days. The results of this study found that asphalt aging had an effect on the characteristics of AC - WC mixture. Values of density, VFB, stability, flow tend to decrease with age. While VIM and VMA values tend to increase with age. Aging caused the mixture to became more rigid.
Brand Loyalty and Repurchase Intention of a Coffee Brand: The Roles of Sensory Attributes, Functional Benefit, and Brand Ambassador
Authors: PANGARIBUAN CHRISTIAN HAPOSAN , PAULINA PUTRI , THAHAR DAIRION 
Published: September 2020

The trend of drinking coffee has resulted in an increase of coffee consumption around the world, including Indonesia. This study investigates the roles of sensory attributes, functional benefit, and brand ambassador towards the intention to repurchase which leads to brand loyalty of Luwak White Koffie. This study uses a quantitative approach by using primary data and distributed questionnaires to 100 employees of various corporations in Jakarta. The data was analyzed through regression analysis. The result of this study shows that functional benefit has a significant influence on both intention to repurchase and brand loyalty. This benefit factor is the most important precedent to both repurchase intention and brand loyalty. On the other hand, sensory attributes do not affect repurchase intention. This type of information can be important to predict or to explain the market response to luwak coffee products, and also to select which sensory attribute(s) should be included in a sensory specification or must be considered in product quality control programs. Another important finding is that, contrary to our expectations, we do not find empirical support for the significant influence of brand ambassador on an intention to repurchase and brand loyalty. The explanation may be that customers currently expect the functional benefit in the form of healthier gastric-friendly white coffee. Moreover, the brand ambassador may not be too influential in the high buying decision among luwak coffee consumers. The relevant contributions that emerged from this study include not only bridging the aforementioned gap in the literature but also offering significant managerial implications to assist organizations to understand the importance of functional benefits toward repurchase intention and brand loyalty.
