PENINGKATAN DAYA DUKUNG TANAH LEMPUNG PADA PERKERASAN JALAN TANAH MENGGUNAKAN DIFA SOIL STABILIZER DAN ABU SEKAM PADI
Authors: Anggara Robby Zul , Amran Yusuf , Surandono Agus 
Published: February 2022

Tanah lempung merupakan tanah yang bersifat multi component, terdiri dari tiga fase yaitu padat, cair, dan udara. Bagian yang padat merupakan polyamorphous terdiri dari mineral inorganis dan organis.Mineral-mineral lempung merupakan subtansi-subtansi kristal yang sangat tipis yang pembentukan utamanya berasal dari perubahan kimia pada pembentukan mineral-mineral batuan dasar. Semua mineral lempung sangat tipis kelompok-kelompok partikel kristalnya berukuran10 koloid (<0,002 mm) dan hanya dapat dilihat dengan menggunakan mikroskop. Tanah yang kurang baik karakteristiknya perlu dilakukan tindakan perbaikan, salah satunya dengan cara stabilisasi tanah sebagai upaya memperbaiki sifat fisik dan sifat mekanis tanah serta meningkatkan nilai CBR tanah. Stabillisasi mekanis atau stabilisasi kimiawi merupakan salah satu upaya yang bisa dilakukang dengan cara menambahkan zatadditive. Pada penelitian ini zat additive yang digunakan yaitu Difa Soil Stabilizer dengan persentase 0,2%, 0,4%, 0,6%, dan 0,8% sedangkan untuk abu sekam padi menggunakan persentase 8%. Menurut sistem klasifikasi USCS, hasil pengujian sifat fisik tanah asli menunjukkan bahwa tanah tersebut memiliki nilai batas cair (LL) rata-rata sebesar 26%, dan nilai indeks plastisitas (PI) rata-rata sebesar 4,95%. Apabila nilai tersebut diplotkan pada diagram plastisitas maka tanah tersebut masuk dalam kelompok lempung anorganis dan lempung berpasir dengan plastisitas rendah. Menurut sistem klasifikasi AASTHO, sampel tanah termasuk kedalam kelompok A-2-4. Tanah golongan ini termasuk tipe kerikil dan pasir yang berlanau atau berlempung. Dari pengujian yang telah dilakukan nilai CBR yang didapat dari tanah lempung berpasir menunjukkan nilai sebesar 4,20% yang mana untuk nilai tersebut belum memenuhi syarat dari Bina Marga yaitu sebesar 6%. Maka dari itu perlu dilakukan stabilisasi mekanis menggunakan Difa Soil Stabilizer dan abu sekam padi. Pada pengujian ini dapat disimpulkan bahwa penggunaan zat additive berupa Difa Soil Stabilizer dan abu sekam padi dapat meningkatkan daya dukung tanah lempung berpasir untuk akses jalan tanah. Terutama untuk CBR tanah dengan meningkatkan persentase zat additive dan kadar air yang tepat maka akan semakin baik pula nilai CBR yang didapat. Pada penelitian ini didapatkan nilai CBR optimumnya sebesar 7,17% pada campuran 0,6% Difa Soil Stabilizer dan 8% abu sekam padi

Published: February 2022

Abstract

Introduction
GLP-1 receptor agonists (e.g., exenatide) are novel drugs used in the treatment of diabetes. These drugs, working with other mechanisms of action, improve glycemic control by increasing secretion of insulin and improving survival of pancreatic islet beta cells. Alterations in the oxidative stress level or the expression of proteins associated with cholesterol uptake might be responsible for those findings. Currently, there are few in vitro studies on the impact of exenatide antioxidant capacity in human islet beta cell lines and none that assess the influence of exenatide on LDL receptors and PCSK9 under hyperglycemia and oxidative stress. Therefore, we evaluated the impact of exenatide on antioxidant capacity, insulin secretion, and proteins involved in cholesterol metabolism.

Materials and Method
An in vitro culture of insulin-secreting cells 1.1E7 was subjected to hyperglycemia and oxidative stress. Assessment was made of the expression of enzymes associated with oxidative stress (NADPH oxidase, catalase, glutathione peroxidase, superoxide dismutase, iNOS) and cholesterol uptake (LDL receptors, PCSK9). Additionally, insulin and nitrite levels in culture media were quantified.

Results
We showed that exenatide improves expression of catalase and reduces the amount of nitrite in cell cultures in a protein kinase A–dependent manner. Those results were accompanied by a drop in the expression of LDL receptors and PCSK9. Insulin secretion was modestly increased in the culture condition.

Conclusions
Our findings show potential protective mechanisms exerted by exenatide in human insulin-secreting pancreatic beta cell line (1.1E7), which may be exerted through increased antioxidant capacity and reduced accumulation of cholesterol.
The effect of lipoic acid on the content of SOD-1 and TNF-α in rat striated muscle
Authors: Skibska Beata , Skibska Agnieszka , Gorąca Anna 
Published: February 2022

Abstract

Background
The aim of the study was to present the effect of lipoic acid (LA) on oxidative stress induced by lipopolysaccharide (LPS).

Materials/Methods
The studies were conducted on male rats of the Wistar strain. The animals were divided into four groups. I: the controls received saline (0.2 ml); II: LPS, received LPS (Escherichia coli 026: B6) at a dose of 6 mg/kg body weight; III: LA, received LA at a dose of 60 mg/kg body weight; IV: LA + LPS, received LA (60 mg/kg b.w.) and after 30 min received LPS (6 mg/kg b.w.). All compounds were administered to the tail vein. After 5 hours of the experiment, the animals were anesthetized and striated muscle from the thigh was prepared. The isolated muscle was homogenized. Concentrations of superoxide dismutase-1 (SOD-1) and tumor necrosis factor alpha (TNF-α) were determined in the homogenates with the application of ELISA.

Results
The study showed a significant decrease in SOD-1 content and an increase in TNF-α in striated muscle after LPS administration. LA given 30 min before administration of LPS caused a significant increase in the level of SOD-1 and decreased levels of TNF-α in homogenates.

Conclusion
LA reduced the parameters of LPS oxidative stress, thus contributing to an increase in the body's antioxidant defense.
Automatic parameter selection ZVD shaping algorithm for crane vibration suppression based on particle swarm optimisation
Authors: Xu Bo , Wang Ran , Peng Baoying , Alqurashi Fahad Abdullah , Salama Mohamad 
Published: February 2022

Abstract
This work introduces the foundation of a new class of input shaping algorithm, designed based on the particle swarm optimisation. This algorithm is utilised to control the residual vibrations in the crane system. The motivation is the development of simple algorithms and architecture for controlling the motion in under-actuated nonlinear systems with minimal modelling effort. By recording the payload swing signal of the crane only once, the approach can automatically calculate the optimisation amplitude and time locations of the impulses required by a common zero-vibration-derivative (ZVD) technique. In this work, we use this algorithm to design a ZVD shaper for controlling the motion of an under-actuated nonlinear crane model system. We validate the approach using experiments. If this algorithm is implanted into the embedded system and applied to the actual crane, which will solve the problem of the traditional ZVD parameter adjustment and improve the vibration suppression effect of the ZVD Algorithm.

The Relaxation Effects in the Preisach - Néel Model of Patterned Media
Authors: Cazacu Ana , Rotărescu Cristian , Bodale Ilie 
Published: February 2022

Abstract
In this paper, we present the calculation of thermal magnetic viscosity based on numerical simulations of relaxation isotherms curves for a Stoner–Wohlfarth ensemble. The Stoner–Wohlfarth particles is described by two equilibrium states and thermal activation is done by overcoming the energy barrier. For simulations we have used a new Preisach type model for Patterned Media, which takes into account the effects of time and temperature. The magnetization of the system is treated using the Preisach Model for Patterned Media with bimodal interactions field distributions. We have simulated relaxation curves starting from different points on the negative region of the descending branch of the major hysteresis loop and from the obtained data we evaluated the thermal fluctuation field. The results obtained for the linear energy barrier were compared with the non-linear energy barrier.
Necessity of Budget Deficit Under Economic Growth in Monopolistic Competition
Authors: Tanaka Yasuhito 
Published: February 2022

Abstract
The aim of the paper is to show, using a simple two-period overlapping generations model in which goods are produced solely by labour in a monopolistically competitive industry, that a continuous budget deficit (including the interest payments on government bonds) is necessary to achieve and maintain full employment under economic growth driven by technological progress. Since the budget deficits must be continuous, it might be better if they were financed by seigniorage rather than government debt. Since the budget deficit due to the issuance of government bonds puts pressure on fiscal expenditures in the amount of interest payments, a budget deficit of the same size due to seigniorage is a more effective use of the budget. It will also be shown that to achieve full employment from a recession with involuntary unemployment the extra budget deficit is necessary.

При зеленом черенковании облепихи сорта Ая-Ганга получают посадочный материал с ценными сортовыми признаками. При укоренении черенков проявляются черты полового диморфизма: черенки, взятые с женских растений, обладают большей регенерационной способностью. Обработка фитогормонами ауксином и цитокинином усиливает процессы корнеобразования, особенно сильно у женских черенков.
When green cuttings of sea buckthorn varieties Aya-Ganga get planting material with valuable varietal characteristics. When rooting cuttings show features of sexual dimorphism: cuttings taken from female plants have a greater regenerative ability. Treatment with phytohormones auxin and cytokinin increases the processes of root formation, especially strongly in female cuttings.
