Authors:   Departement of Dermatovenereology, Faculty of Medicine, Diponegoro University / Dr. Kariadi Hospital, Dr. Sutomo street No. 16 Semarang-Indonesia.
Published: May 2021

Background: Acne vulgaris is one of the most prevalent skin diseases, affecting up to 85% of teenagers and young adults. Multiple treatment options including topical, systemic or physical therapies. However, the effects of conventional therapies are limited due to antibi-otic resistance and adverse effects such as irritation and teratogenicity of isotretinoin. Light-based therapy is an alternative and/or adjuvant therapy in patients who cannot tolerate or unresponsive to conventional therapies that may provide fewer side effects, patient com-fort, fast onset of action, and with equal or greater effectiveness. We aimed to assess the effectiveness of using Pulsed Dye Laser as a treatment option for acne vulgaris. A systemat-ic Review and Meta-analysis was peformed of randomized clinical trials assessing the ef-fectiveness of Pulsed Dye Laser in management of acne vulgaris. Methods: Medline Pubmed, Scopus, Cochrane library, the reference list, conference pro-ceedings, researchers in field of eligible studies were searched. Eight studies (n=275 sub-jects) were included in qualitative analysis of which six studies (n=190 subjects) were in-cluded in meta-analysis. The mean age of the participant was 21,94 years old. Intervention using application of Pulsed dye laser as monotherapy or combination in acne vulgaris pa-tients with follow-up at least 12 weeks. and the outcomes is a decrease mean of acne vul-garis lesions counts after received pulsed dye laser therapy. Results: Pooling of data using random effects model showed that the group that received PDL therapy alone or in combination had a lower number of acne lesions than the control group with the mean difference was -0.593 (95% CI = -1.290 to 0.104), the z value was -1.668 with p = 0.095. This shows that the number of lesions in the group that received sin-gle or combined PDL therapy was lower than the control group. However the difference is insignificant. Conclusion. From the results of the systematic review conducted, it can be concluded that in the group given Pulsed Dye Laser therapy there was a decrease in the total number of acne vulgaris lesions compared to before treatment, and the decrease, which was indicated by the difference in the mean number of acne lesions, was significantly greater compared to the control who was only given placebo. Pulsed Dye Laser therapy can be an alternative treatment option for acne vulgaris in patients who are unresponsive to previous treatment or conditions where there are contraindications to systemic therapy.
Bearing Capacity Factor of Circular Footings on Two-layered Clay Soils
Authors: Benmoussa Samir , Benmebarek Sadok , Benmebarek Naima
Published: May 2021

Geotechnical engineers often deal with layered foundation soils. In this case, the soil bearing capacity assessment using the conventional bearing capacity theory based on the upper layer properties introduces significant inaccuracies if the top layer thickness is comparable to the rigid footing width placed on the soil surface. Under undrained conditions the cohesion increases almost linearly with depth. A few theoretical studies have been proposed in the literature in order to incorporate the cohesion variation with depth in the computation of the ultimate bearing capacity of the strip and circular footings. Rigorous solutions to the problem of circular footings resting on layered clays with linear increase of cohesion do not appear to exist. In this paper, numerical computations using FLAC code are carried out to assess the vertical bearing capacity beneath rough rigid circular footing resting on two-layered clays of both homogeneous and linearly increasing shear strength profiles. The bearing capacity calculation results which depend on the top layer thickness, the two-layered clays strength ratio and the cohesion increase rates with depth are presented in both tables and graphs, and compared with previously published results available in the literature. The critical depth for circular footing is found significantly less than for strip footing. Doi: 10.28991/cej-2021-03091689 Full Text: PDF
Optimization of Bituminous Pavement Thickness using Mechanistic-Empirical Strain-Based Design Approach
Authors: Sahis Manoj Kumar , Biswas Partha Pratim
Published: May 2021

The pavement in this paper has been considered as a three layered system with the top layer of bituminous mix followed by unbound granular layer which rests on soil subgrade. The objective of the paper is to develop an optimization method based on mechanistic –empirical approach for estimation of bituminous and granular layer thickness. Two major modes of failure as rutting and fatigue have been considered for structural design of bituminous road section on strain based criteria. The vertical compressive strain on the top of subgrade and radial tensile strain at the bottom of bituminous layer have been determined by Boussinesq’s theory after transforming the three layered system in to a homogeneous system by Odemark’s method. The findings from the present study reveals that only one typical combination of bituminous and granular layer thickness is possible to save the pavement both against rutting and fatigue. The result of layer thickness obtained using present methodology was compared with other international published data and was found in good agreement. The pavement deflection as a performance indicator for the optimized pavement section thus obtained have been determined by Odemark's-Boussinesq's approach and compared with the deflection obtained using IITPAVE and KENPAVE software, which show reasonable good convergence. Doi: 10.28991/cej-2021-03091691 Full Text: PDF

Published: May 2021

Global warming and climate variability are emerging as the foremost environmental problems in the 21st century, especially in developing countries. Full knowledge of key climate change variables is crucial in managing water resources in river basins. This study examines the variability of air temperature and rainfall in the five states of South-Eastern region of Nigeria, using the trend analysis approach. For this purpose, temporal trends in annual rainfall and temperature were detected using non-parametric Mann-Kendall test at 5% significance level. The time series rainfall and temperature data for the period 1922-2008 were analyzed statistically for each state separately. The results of Mann Kendall test showed that there is trend in rainfall in all the capital cities in South-East except Owerri and Awka. It is also observed that the trend of rainfall is decreasing for all the study areas in South-East with the lowest trend rate of -0.1153 mm rainfall occurring in Umuahia. In the case of air temperature, it is observed that the trend is increasing for all the study areas in South-East with the highest trend rate of 0.04698 oC/year occurring in Enugu. These findings provide valuable information for assessing the influence of changes on air temperature and rainfall on water resources and references for water management in the South-Eastern river basin of Nigeria. It also proved that Mann-Kendall technique is an effective tool in analyzing temperature and rainfall trends in a regional watershed. Doi: 10.28991/cej-2021-03091692 Full Text: PDF

Published: May 2021

Water is one of the main constituents of concrete. Although many types of water exist, fresh water is the mostly used in concrete industry. Fresh water is expected to be in a great shortage by 2050 according to UN world water development report. Incorporating seawater in concrete mixture can help in the expected problem of scarcity of fresh water. Also, in many cases seawater may be the only available water especially in coastal regions. Many reports mention various possibilities of using seawater in concrete without detrimental effect on concrete properties. In this study another beneficial effect of seawater over tap water was concluded. Setting tests of cement paste mixed with seawater was determined using Vicat apparatus and compared to tap water. Compressive strength tests at the age of 28 days of Portland cement concretes with varied quantity of cement i.e. 300, 350, 400, 450, and 500 kg, and mixed with seawater was also performed and compared to tap water. The results show that seawater affects standard consistency of cement paste and two percent increase was required in order to attain the same consistency as tap water. It shows also seawater slightly accelerates initial setting of cement but the effect is not so pronounced so as to cause a trouble in concrete and final setting time almost remains unaltered. Compressive strength tests show an increase in concrete strength mixed with seawater for all tested mixtures and depending on quantity of cement. It also shows a beneficial effect of seawater on compressive strength of rich concrete with quantity of cement 450 and 500 kg over tap water. Doi: 10.28991/cej-2021-03091695 Full Text: PDF
A New Simplified Prediction Method of the Contact State between Shallow Foundations and Swelling Ground
Authors: Farid Z. , Lamdouar N. , Bouziyane J. Ben
Published: May 2021

Prediction of the contact state between soil and structure is a key step in any study of shallow foundations resting on swelling soil. However, in practice, the foundation designer has no simple and rapid method, at the design stage, to define the contact conditions. This study presents a new method, both simple and reliable, to predict the contact state. To do this, a soil-structure interaction model is developed. The building behavior is investigated with the Euler–Bernoulli beam theory and the ground behavior is investigated with a Winkler model. The soil-structure interaction is then, studied at the equilibrium state. The thereby obtained equation is analyzed and all of its parameters are synthesized in a new factor named "Detachment Factor". The decidability of the contact is thus reduced to the study of this single element, which allows a reasonable approach to the knowledge of the surface rate engaged in the shallow footings - expansive soil interactions. The conclusions of the current study are validated against five cases treated in the literature in various regions around the world. In addition, a parametric study of the “Detachment Factor” shows that each of its parameters (i.e. swelling stiffness, shape of initial soil surface, permissible deflection, structure geometry and loads) has a variable effect on the contact state between a footing and swelling ground. But, the structure load has the most significant effect on it. Doi: 10.28991/cej-2021-03091697 Full Text: PDF

As an effort to improve the knowledge and skills of rural breeders, community service activities have been carried out with the topic "Training on Feed Processing from Agricultural Waste in Moyo Mekar Village of Moyo Hilir Sumbawa." This service activity was held on the grounds that breeders in Moyo Mekar Village often experience difficulties to meet the needs of their livestock for forage, especially during the dry season, so this sometimes has an unwanted negative impact, such as the occurrence of cases of death and disease in livestock as a result of the declining condition of the livestock. This is due to the ignorance of the breeders in their efforts to overcome the shortage of forage during the dry season. This community service activity has been carried out using three methods, namely lecture, written and demonstration methods. With the lecture method, it was conveyed about the understanding and explanation of how to preserve and treat agricultural waste. Through the written method, it is conveyed by giving brochures to the breeder members. Meanwhile, with the demonstration method, the breeders directly practice ways of preserving and treating agricultural waste. Based on the results of monitoring during the activity, the results of questions and answers and the enthusiasm of the participants, it was seen that the new breeders realized how important the role of nutrition was for livestock, the availability of applying preservation and feed processing technology, and it could also be seen that they had no difficulty in adopting the material provided, then Overall this activity can be said to be quite successful. Recognizing the limitations of the breeders in terms of preservation and processing of feed which is an alternative for providing feed in the dry season, it is suggested that this kind of activity should be continued so that the expected livestock production can be achieved.

Due to a high construction material cost in Ethiopia, it is difficult to afford a shelter by most our peoples. The Hydra form block (HFB) has been identified as low-cost building material with its potential and possibility to reverse the housing problem. Laboratory tests were conducted on Mettu, Nopa, Gore, and Hurumu areas soil. Using hydra form machine with average mold size of 29*14*10cm, hydra form blocks were casted with the three percentages increment of cement. Compressive strength and water absorption tests were conducted at 28 days. The investigation has revealed that all the soil sample except Gore soil have significant characteristics that make it suitable for stabilization with recommended soil properties. From the experimental study, all the blocks except blocks produced with Gore soil have 28th day compressive strength values well above most of the recommended minimum values. Water absorption was less than the maximum limit of 15%. But, for control block and for stabilized with 3% cement, water absorption result is out of the recommended values (0-15) %. The cost comparison of Hydra form blocks with hollow concrete block and fired clay brick shows that the Hydra form block is cheapest walling material in terms of production cost and a typical hydra form block production center can create a job for more than 50 peoples.

Nowadays, organic foods are recognized for having a better nutritional quality than those from conventional agriculture, which explains the growing demand for organic vegetables. For the present research, three tomato cultivars, Mongal F1, Roma VF and F1 Cobra 26 were grown using conventional and organic methods, to assess the impact of cultivation practices and drying method on the micronutrient content of these cultivars. Samples were compared for micronutrient content of lycopene, β-carotene, flavonoids, vitamin C and total content of phenolic compounds using the FRAP and DPPH methods. The results show a high antioxidant activity (5901.338 mmol TE/100g and 6020.545 mmol TE/100g) and a high content of total polyphenols (1595.046 mg EAG/100g DM) for organic growing. The average contents of flavonoids (121.572 mg/100g DM and 129.053 mg/100g DM), β-carotene (39.618 mg/100g DM and 39.751 mg/100g DM), lycopene (169.739 mg/100g DM and 168.894 mg/100g DM) and vitamin C (301.995 mg/100g and 268.252 mg/100g DM) in tomatoes from organic and conventional cultivation show no statistically significant difference. After drying, results report an increase of 188.88% of Flavonoids content (from 62.413 ± 47.285 for mashed tomato to 180.304 ± 72.152 for dried Tomato); a decrease of 34.60%, 27.18% and 47.95% respectively for β-carotene content (from 47.388 ± 1.615 mg /100g DM for mashed tomato to 30.988 ± 0.767 mg /100g DM for dried tomato), lycopene content (from 188.085 ± 7.100 mg/100g DM for mashed tomato to 136.955 ± 2.810mg/100g DM for tomato dried) and vitamin C content (from 385.686 ± 37.825 mg/100g for mashed tomato to 200.743 ± 14.181mg/100g DM for dried tomato). There is variability in the micronutrient content depending on the variety of tomato, the cultivation practice and the processing technique used. Organic cultivation practice improves the micronutrient content. Using gas dryers for drying has the most detrimental effects on the micronutrient content.

Field trials were conducted in savannah woodland (Njala) and rainforest (Serabu) agroclimatic regions of Sierra Leone during 2016 second cropping season to assess different preemergence herbicides techniques that is efficient, cost effective and environmentally safe in cowpea production. The experiment consisted of 20 treatments which included 2 cowpea genotypes (slipea 4 and slipea 5) and 10 different weed control techniques viz: butachlor 50% emulsifiable concentrate (EC), double force®, power force® applied as preemergence herbicides at 2, 4 and 6 L ha-1, respectively and weedy check. The treatments were laid out in a strip-plot design arranged in a factorial system with three replications. The results of this study revealed that the application of power force® at 6 L ha-1 recorded the highest phytotoxic effect, lowest weed dry weight, number of pods per plant and grain yield, highest total variable cost, lowest gross and net returns. Furthermore, butachlor 50% EC at 2 L ha-1 closely followed by double force® at 6 L ha-1 resulted in maximum grain yield, gross and net returns compared to the rest of the other weed control techniques. Thus, it is concluded that butachlor 50% EC at 2 L ha-1 was more economical, profitable and beneficial than other control treatments in the production of cowpea genotypes in the savannah woodland and rainforest agroclimatic regions of Sierra Leone. Conclusively, the relationship between phytotoxicity and grain yield indicates that the higher the grain yield the lower the phytotoxic effects of the chemicals.

Every virus is a parasite that cannot exist on its own and is fully dependent on its carrier. This is the basic condition of its existence. The parasite must have its host, and thus is a living cell, but it is generally claimed that the virus can exist without a carrier for 2 to 5 seconds, during which it is transmitted to another species. Following these viral pathways is not easy and has not been fully investigated. However, this is a key issue that can lead to a major paradigm shift in the way we perceive viruses. The primary carrier, however, cannot be host organ cells because they could easily damage them. In terms of the mechanism of existence and transmission, the following could be the most suitable carriers of the virus: bacteria, yeast or other single-cell organisms.

Nephroblastoma or Wilms tumor is a malignant tumor that develops at the expense of embryonic kidney tissue. It is the most common kidney tumor in children (> 90%); it represents around 5% to 14% of all childhood cancers. The aim of our work is to recall the contribution of imaging, in particular CT, in the management of this renal tumor. This is a retrospective, single-center study of 136 cases of Wilms tumors diagnosed in our clinic over a 2-year period. The mean age of the patients was 04 years with an extreme of (3 months -12 years) with a female prevalence (8 girls for 5 boys). Abdominal mass dominated in our study in clinical information. Histological confirmation was found in 12 cases, the only non-conforming case was lost to follow-up.

Queuing is an activity where parties are waiting to get service. A queuing process starts from the time of arrival to the time of service. Queuing problems are often encountered in everyday life, including in Langsa City Hospital, especially in the cardiac clinic, which has the most patients. The majority of patients in the queue system are elderly (elderly), so good service is needed considering the physical condition of patients who have entered a vulnerable age. The queuing system analysis aims to determine the average number of patients waiting in the system and the length of service at the heart clinic of Langsa City Hospital. In addition, the queue system analysis can help the Langsa City Hospital design an operational service system so that the service process can run optimally. The queue structure model used is a single channel-single phase with the discipline type First In First Out (FIFO). From the queue model analysis results obtained, the cardiac poly care system has an average number of patients waiting at most occurs in the period 08.00-10.00, namely 14 people with a waiting time of about 56.28 minutes. This time is the busy working hour at cardiac poly with a busyness rate of 93%. From the simulation results with two servers using the same model, a busy rate of 50% was obtained with a reduction in the number of people waiting by 12.8 people with a waiting time of about 1.2 minutes.

The Miquel theorem is a theorem that applies to a triangle, namely the inner Miquel theorem and the outer Miquel theorem triangles—then developed on the quadrilateral. As of this writing, it is developed in any of the pentagons. Miquel's theorem development in any pentagon is divided into two cases, namely in the convex and non-convex pentagons. This process begins with the construction of the inner Miquel point in any triangle using the GeoGebra application. While proving the internal Miquel theorem for any pentagon uses a simple concept, namely the concept of circles and cyclic rectangles so that five circles intersect at a point called the inner Miquel point at any pentagon.

North Sumatra is one of the endemic areas of tropical diseases, one of which is filariasis. Filariasis or elephantiasis is a disease transmitted through mosquitoes and can cause permanent physical disability for sufferers. In 2015, there were 127 filariasis sufferers. This number has increased to 164 patients in 2017. As a prevention effort, the government provides mass treatment for people living in endemic areas of the disease. Therefore, this study aims to determine the model of spread and the effect of treatment on these communities. This study uses an SEIR model consisting of susceptible humans (S_h), infected humans (E_h), infected humans (I_h), and immune humans (R_h). The data used is data on filariasis sufferers in North Sumatra in 2010-2019, obtained from the North Sumatra Health Office. The data were analyzed based on the equilibrium point, stability, basic reproductive ratio, and numerical simulation. The results showed that based on the SEIR model, filariasis treatment could suppress transmission in endemic areas.

Mathematics is an essential subject to study so that it must be pursued in its implementation and possible. The existence of the covid-19 pandemic requires all learning activities to be carried out online. But in practice, online learning experiences several obstacles, especially in learning mathematics. For this reason, the purpose of this study is to describe the constraints in the online-based mathematics learning process (e-learning). This study uses a descriptive method with a qualitative approach. The subjects in this study were students of class VIII SMPN 1 Rawamerta. The research instrument was in the form of a student response questionnaire regarding online-based learning (e-learning), which consisted of seven closed questions and four open questions. Data collection was carried out by distributing the google link form to the student response questionnaire to the research subject. Data analysis was carried out descriptively by testing the validity of the data through triangulation techniques. The results showed that students' obstacles in online-based mathematics learning (e-learning) were technical and personal constraints. Technical constraints are in the form of an unstable internet network, internet quota, and teacher explanations that are not heard clearly. In contrast, unique constraints are the lack of students in understanding the learning material and feeling lazy to take online-based mathematics learning.
