Published: October 2020

Conventionally, cement deep mixing (CDM) columns are designed to have constant diameters over the improved depth as this facilitates the construction procedures. However, this design pattern may be inefficient in cases of spread footings or shallow foundations. This paper first briefly introduces principles, construction procedures and quality control techniques of an innovative CDM method that can create head-enlarged column, named as Point Foundation (PF). The method is practically implemented with a specific binder that is environment-friendly and more effective in strength enhancing compared with the common binder as cement. Static load tests on three instrumented PF columns indicate that the variation trend of induced vertical stress profile along the columns in general is similar to that under the centre of shallow footings on elastic soil medium. However, the stress profile in the (semi-rigid) PF columns is larger than that in elastic soil but less than that in (rigid) PHC pile. This confirms the load transfer mechanism along semi-rigid columns like CDM/PF. Test results also indicate that at the depth of one to two times head diameters the induced stress remains just 20% the applied pressure. Findings on the trend of the induced vertical stress in the columns suggests that the settlement of common shallow footings on CDM/PF column-reinforced grounds should be evaluated using 3D condition taking into account the fact that the induced stress decreases with depth.

Published: October 2020

Bê tông thương phẩm (BTTP) ngày càng được sử dụng phổ biến do có nhiều ưu điểm so với bê tông trộn tại công trường. Tuy nhiên, để đảm bảo tính công tác và khả năng bơm tốt, bê tông thương phẩm thường phải sử dụng lượng xi măng lớn hơn. Để khắc phục vấn đề trên, việc sử dụng phụ gia khoáng thay thế một phần xi măng là cần thiết. Trong nghiên cứu này, tro bay được sử dụng để thay thế xi măng với tỷ lệ từ 10-40% theo khối lượng trong bê tông thương phẩm M300 và M600. Kết quả nghiên cứu cho thấy, khi thay thế một phần xi măng bằng tro bay làm tăng tính công tác của hỗn hợp bê tông (HHBT), tổn thất tính công tác của hỗn hợp bê tông sử dụng tro bay không khác nhiều so với bê tông không sử dụng tro bay. Khi thay thế đến 20% xi măng bằng tro bay theo khối lượng, cường độ nén của bê tông giảm nhẹ và vẫn đạt mác thiết kế. Tuy nhiên, khi sử dụng 30% tro bay, cường độ nén của bê tông giảm một mác so với cường độ thiết kế. Khi sử dụng 40% tro bay làm giảm đáng kể cường độ của bê tông ở tất cả các tuổi, mức giảm quan sát được từ 31,4% đến 41,6%.

Cardiovascular Effects of Listening to Fast Speech and Normal Speech
Authors: Quartey Perez , David TA Blemano , Patience Odoi 
Published: October 2020

Background: Some previous works on the psychological impact of speech on the cardiovascular system have mainly focused on the speaker as the individual in whom clinical outcomes are being measured. There is limited data on the effects of listening to the fast speech on cardiovascular responses.
Aim: The aim of the study was to comparatively examine blood pressure and heart rate changes upon listening to normal and fast speeches.
Method: A total of 88 (22 females and 66 males) normotensive adults were recruited for the study from a university population. All subjects were made to listen to two different 13-minutes audio recordings of normal speech (news commentary) and fast speech (a radio sports presentation). Blood pressure and pulse rate changes were taken at 4-minutes time intervals during listening to the audio recordings. Based on the enthusiasm and patronage of the sports program, participants were classified as ‘‘Regular’’ listeners and ‘‘Non-regular’’ listeners. Blood pressure and pulse rate changes were calculated as the mean net area under the curve response and differences were analysed with analysis of variance.
Results: Systolic, diastolic and pulse rate responses were significantly higher in both the Regular and Non-Regular listener groups during listening to the fast-speech audio presentation as compared to the News Commentary presentation.
Conclusion: Although there is limited data, listening to fast speech itself may act as a psychosocial stressor that predisposes to an increased cardiovascular response manifested as higher blood pressure and heart rate.

Published: October 2020

Falling in love is one of all the great feelings in the world. Humans are not the only one among the huge diversity of species to fall for it. Combine bonding, the two-by-two partnering of creatures have been seen across the fauna. To fall in love and be enamored allows an individual to depict himself charmingly alive. Most folks will reminisce at least one time in their lives of experiencing “butterflies in their stomach”, or a sense of ‘losing oneself’ into a deep ocean of affectionate feelings for someone. We tend to encounter ourselves into being obsessional and few might have delineated their feelings as going mad for that person. Though all these descriptions appear to be magnifying the words or phrases which we come across in daily life, there appears to have some hidden facts to these thoughts and behaviors. Have you ever thought, from where would be these sensations, obsessional thoughts and sometimes out of character acts arising from? Are there any particular physiological changes occurring in our body which are answerable to the arousal of these feelings?
The knowledge available to biologists have advanced vastly within the previous few decades and are using that information in deciphering the Physiology involved in both combined bonding and being in love. This review could prove engrossing and to converse about the physiological basis of affection, specially metamorphology of love in various phases of life, biological basis, neurochemistry, the neuronal circuits of affection and finally concerning over the myth of ‘ Everlasting Love’.

Authors: Linda Andriani Raden Ayu , Zen Ahmad  
Published: October 2020

Background. Resistance to the INH drug is most often caused by a mutation of the KatG S315T M.Tb gene. MDR TB treatment with short-term WHO mixes using high-dose INH drugs is considered less effective in this mutation condition because it causes high resistance to INH. The effectiveness of MDR TB treatment can be seen from the sputum smear conversion rate. This study was aimed to determine the effect of the S315T katG gene mutation on the treatment response of patients with MDR TB who received WHO short-term alloys at Dr Moh Hoesin general hospital, Palembang, Indonesia.
Method. This study uses observational analytic with a prospective cohort approach. The study subjects were MDR TB patients at Dr Moh Hoesin general hospital, Palembang, Indonesia, and a PCR-RFLP examination was performed to see the katG gene, followed by sputum smear evaluation at the end of the first and second months of treatment to assess the speed of conversion. Data analysis using SPSS 25 with the chi-square statistical test.
Results. The frequency of katG S315T M.Tb gene mutations was 51.85%. The majority of MDR TB sufferers experience rapid conversion (92.59%). 64.29% of the katG S315T gene mutation group experienced sputum smear conversion after one month, 28.57% after two months, and 7.14% after three months of treatment. There was no significant difference in conversion speed in the two groups (p = 0.741).
Conclusion. There was no effect of the S315T M.Tb katG gene mutation on the speed of sputum smear conversion of MDR TB patients who received short-term alloy treatment.

This study hypothesize that lidocaine and ketamine combination reduces pain intensity, improves functional state and central desensitization of chronic low back pain. It is by modulating central sensitization in sub-anesthetic dose, prolonging inactivation of Na-channel, blocking NMDA-receptor and preventing secondary hyperalgesia.
Aim of study: To evaluate the efficacy of lidocaine and ketamine combination on the intensity of pain, functional state and central desensitization of chronic low back pain.
Methods:. This double blind randomized control trial study was carried out in Mohammad Hoesin General Hospital, Palembang, Indonesia from May 2018 to January 2019. A total of 20 patients with low back pain that last for more than 3 months, aged >18 years old, of either sex who were willing to be enrolled in this study, were randomly allocated into one of the two groups of 10 each. The treatment group (n=10) received standardized therapy (analgesic and physiotherapy) + intravenous ketamine 0.5 mg/kg + lidocaine 2 mg/kg and the control group (n=10) received standardized therapy + 100 ml Nacl 0.9%. Pain intensity, functional state, and central desensitization were measured before the treatment, day 7 after treatment, and a month after treatment using Numeric Pain Rating Scale (NPRS), Functional Pain Scale (FPS), and Central Sensitization Inventory (CSI).
Results: The administration of ketamine 0.5 mg/kg + lidocaine 2 mg/kg resulted in NPRS and CSI changes was effective since the 7th day post intervention (p-value=0.021 and p-value=0.001) while on FPS changes, it was effective since the 30th day post intervention (p-value=0.000)
Conclusion: From the result, it could be concluded that the administration of ketamine and lidocaine is effective on decreasing pain intensity and central desensitization in chronic LBP.

A Novel Switching Control for Induction Motors Using a Robust Hybrid Controller that Combines Sliding Mode with PI Anti-Windup
Authors: Aichi Bilel , Kendouci Khedidja 
Published: October 2020

Induction Motors are the most used machines in the industrial field since the last century, due to their low cost, high robustness with satisfactory performance. However, they are still difficult to control compared to the DC motor because of the non-linearity presented in the mathematical model. Sliding mode theory is often used to develop powerful control against various internal and external disturbances. However, the chattering problem caused by the attractive part of the regulator is a serious problem for its applications. In this paper, the proposed solution for having an optimal performance consists in combining the Sliding Mode Control with an anti-windup proportional-integral regulator. This is achieved through a simple linear supervisor that can activate the sliding mode at start-up and transient regimes while making the second controller drive the steady state. The asymptotic stability of the delivered control signal is ensured via the Lyapunov method. This allows us to benefit from the advantages of the two regulators without having their disadvantages. This new hybrid technique can potentially offer very promising results in terms of robustness and control efficiency. The validation of this theory was carried out by simulation and then by practical implementation using a dSPACE-DS-1104 control board. The obtained results show a high-performance control with very good robustness against parametric variations and remarkable stability during all different operating zones.
