Nowadays, it has become a crucial task in transferring confidential data for military departments, many multinational companies, etc.Â The important requirement is that the data that has been transmitted should not be visible to hackers or third parties from another end. To satisfy this requirement a wireless technology LoRa is used. Long-distance and low-power wireless communication technologies such as LoRa, Sigfox, and Narrowband-Internet of Things (NB-IoT) were developed in recent years. These technologies can contribute to indoor and outdoor smart applications with minimal power consumption. In this study, the LoRa wireless communication technique was used as the primary data communication method, enabling the device to communicate without requiring an Internet connection or a SIM card. This technology can be implemented in military and defense areas.

Railway bridge Bangunan Hikmah (BH 39) Pariaman (Padangâ€“ Pariaman Route) is a new bridge. This new bridge was built because the old one could not accommodate the load of the additional locomotive. The railway bridge consists of two parts: the upper structure and the substructure. The substructure consists of abutments and foundations. When the abutment accepts considerable lateral ground pressure, so the stability of the abutment will be disturbed. To resolve the problem, the need exists to study abutment reinforcement with geotextile or additional foundation pile to raise the stability abutments on the Railway bridge Bangunan Hikmah (BH 39) Pariaman. The result of the loading on the upper structure is obtained. The total vertical force acting on the abutment is 6111,624 kN, and the horizontal load is 2849,689 kN. Abutment stability analysis is carried out in 3 stages (without reinforcement, with reinforcement geotextiles, and with existence foundation pile (bored pile). The results of the analysis show value safety factor minimum without Reinforcement (SF) is 1,29; this shows that the abutment is unstable because the safety factor obtained is < 1.5, Â with reinforcement geotextile, the value of the safety factor minimum Â (SF) is 1,66, Â this indicates that the abutment is stable but still critical and the value of the safety factor (SF) minimum with bored pile foundations is 2,10. Â Installation of a bored pile foundation (pile group) at a depth of 10m shows a significant increase in the value of the safety factor. In the BH 39 Kurai Taji Pariaman railway bridge project, it is recommended to use a pile group foundation with a depth of 10 m.

Automotive exterior spare parts retailers frequently sell exterior spare parts for a range of cars via direct sales transactions and online media. A major issue has come up for consumers who purchase products online must install spare parts independently, with limited instructions that make it difficult for customers to install the replacement components. This is demonstrated by nearly 50% of online consumers complaining to the seller about installation errors, indicating the need for a solution to these issues. Augmented reality was used as a solution to educate how to install automotive exterior spare parts. In this work, the Spatial Tracking technology is utilized to project objects from a viewpoint in order to send data digitally and show the 3D model to the object's surrounds in real time.Â This study included as samples rear-view mirrors, headlights, stop lamps, and fog lamps. According to the study's findings, The user acceptance test was carried out by online consumers who buy spare parts at the store, and the results of the average percentage score of the entire questionnaire by more than 53% agree and strongly agree that the use of augmented reality can ease the spare-part installation bought online, the results of testing the AVAR application by the user are successful and well accepted.

Published: March 2024

In the development of 4G LTE technology, network speed (Throughput) in several regions has increased or decreased. Network speed (Throughput) certainly cannot be separated from Modulation.Â In modulation there are several kinds of modulation schemes, be it QPSK modulation, 16 QAM modulation, and 64 QAM modulation. The modulation scheme is instrumental in increasing throughput. Based on several previous studies, they only check the Throughput parameters without doing a more in-depth analysis of the modulation scheme which also plays a very important role in network speed (Throughput). For this reason, it is necessary to carry out an analysis related to the effect of modulation on the throughput value. To find out the effect of modulation on throughput, it is necessary to take data in the field, the method used is the Drive Test method. Based on the results of the Drive Test, QPSK modulation has a Throughput value of 5.247.4 Kbps, modulation of 16 QAM has a Throughput value of 27.293.9 Kbps and modulation of 64 QAM has a Throughput value of 65.275.1 Kbps. Based on the data in the field and in terms of calculations, the modulation that most affects the throughput value is the modulation of 64 QAM. Modulating 64 QAM having 64 symbols where each symbol consists of 6 bits will make the data rate at throughput higher. This also applies to the use of modulation of 16 QAM (16 symbols with 4 bits) and QPSK (4 symbols with 2 bits).

Published: March 2024

Rural areas are indicated to be still difficult to reach by 4G signals due to diverse topographical conditions and uneven landscapes, especially hilly areas that weaken the signal reception level in this region. To make the 4G signal accessible in this area, a repeater in the form of an antenna is needed to strengthen the signal. In this study, a yagi antenna is designed with three reflector elements at a working frequency of 1800 Mhz 4G LTE, expected to produce a minimum gain of 12 dBi and a more focused antenna radiation to strengthen the 4G signal in rural areas. The antenna design was simulated using CST Studio Suite software, with optimized simulation results yielding a return loss of -22 dB, VSWR 1.167, and gain 12.40 dBi. From the measurements obtained, the yagi antenna with three reflector elements works well at a frequency of 1800 Mhz, with a return loss of -34.77 dB, VSWR 1.065, gain 12.96 dBi, and unidirectional radiation. With the optimal antenna parameters and the addition of three reflector elements, it's possible to increase the gain value, even though the gain increase isn't substantial, and it narrows the HPBW (Half Power BeamWidth) value. Moreover, testing the yagi antenna at 3 different distances demonstrated that the resulting gain value can enhance 4G signal speed in rural areas

Published: March 2024

Eye disease is a serious issue all over the world, and image-based classification systems play an important role in the early detection and management of eye disease. This research compares the performance between Random Forest (RF) and K-Nearest Neighbor (KNN) classification models in identifying eye disorders using image datasets divided into four classes: "normal," "glaucoma," "cataract," and "diabetic retinopathy."Â Â The dataset is converted into a feature vector and then divided into training data and test data subsets. The analysis results show that the RF model achieved an accuracy level of 80%, whereas the KNN model achieved 70%. Based on these findings, it is possible to conclude that the RF model outperforms the other models in categorizing the types of eye illnesses in the dataset. A Python-based website was also built utilizing the Flask framework to build an interactive and real-time eye illness diagnosis system. Users can upload photos of their retinas to this website and quickly receive eye disease detection results. The adoption of this technology has a tremendous impact, making eye disease detection solutions more accessible. Furthermore, this solution plays an important role in the early detection and effective management of eye health cases.

Nature lover student (mapala) students who often carry out natural exploration activities. Mapala must have the ability to survive and recognize plants that are useful for food and medicine. The limited information that Mapala has about plants in the wild indicates that they need relevant and accountable sources to be able to survive in difficult times. One way to provide sources of information to students is through counseling. The methods used in carrying out this activity are lectures or counseling, discussions, demonstrations, and evaluations. Data collection techniques during counseling using questionnaires and interviews. The counseling activity was carried out at the Paksi Arga Nature Lovers Student Group, Padang Institute of Technology. The participants in this activity were attended by 15 nature-loving students at the Paksi Arga Institute of Technology and the organizers consisted of 4 lecturers and 2 students. The output results of the independent t-test show that the Sig value is <0.05, so there is a significant difference between mapala knowledge before and after counseling. Difference in percentage There is an increase in knowledge that plants that can be used for survival are as big as20,6%, edible plants for survival 27%, and plants that can be used as medicine 22,64%.

The aim of this study is to go inside the mode of action of Narcissus cv. Hawera leaves' extract on Chlamydomonas reinhardtii by analyzing its chemical composition, genotoxic, mutagenic, and DNA damaging effects.
GC/MS analysis of the methanol extract shows that alkaloids comprise about 23.93% of the total ion current (TIC). Considering the alkaloid pattern, lycorine is the major alkaloid (8.53% of TIC), followed by 6-epi-mesembrenol (4.59% of TIC), galanthamine (2.63% of TIC), and mesembrenone (2.01% of TIC). Other compounds in the extract are mono- and di-saccharides, organic acids, and fatty acids.
Based on our experiments, both well-expressed genotoxic and DNA damaging potential of Narcissus cv. Hawera total leaves' extract was revealed for the first time. The most pronounced effect is obtained after the treatment with concentrations equal to or higher than 500 μg/ml. Cell survival decrease in a dose-dependent manner correlates with increased levels of induced DNA double-strand breaks (DSBs) but does not correspond with statistically confirmed mutagenic action. A good correlation is obtained between the levels of DSBs induced and cell survival rate.
Here, for the first time, experimental evidence that Narcissus cv. Hawera leaves' extract can cleave DNA of Chlamydomonas reinhardtii inducing DSBs was reported by us. Our finding could be considered a good reason for further investigation of its biocidal capacity on other test systems for the purposes of “green” practice.
Lateral Sinus Floor Elevation in Cases of an Intact and Perforated Schneiderian Membrane

Published: March 2024

The study comprised 20 lateral sinus floor elevation cases performed in 18 patients. During surgery, in four cases, a perforation of the Schneiderian membrane was detected. An attempt to suture the perforated membrane may increase the risk of enlarging the perforation. Therefore, we suggest a more conservative protocol be applied in all four cases where perforation occurred. The procedure consists of the 3-layer technique: an absorbable oxidized cellulose gauze moisturized with Dicynone was placed in this area. Under it, as a second layer, a PRF membrane is applied and then covered with a slow-resorbable collagen membrane. At that point, the surgery continues with the placement of the bone substitute material, and the sinus-lifting is finalized according to the selected protocol.
The clinical studies demonstrate that the bone graft has a slower healing rate in areas with perforation, which is a proof of the osteogenic properties of the Schneiderian membrane. The cases described reveal that using this surgical protocol is risk-free and has a high success rate.
Competence as an element of “mediation readiness”

Published: January 2008

AbstractThis article introduces a specific standard to the mediation community with the idea of sparking debate that would lead to a commonly accepted standard for competence to participate in mediation for divorce. It delineates the broad contours of an assessment process using the proposed standard and examines practical implications and next steps for mediators related to the establishment of a common standard. It then describes how the proposed standard could be incorporated in mediation trainings, model rules, and state statutes and regulations, leading to more uniform and equitable decisions and increasing the pro‐cedural fairness of divorce mediations within and across jurisdictions.
Sustainable industrial development and environment protection: An emerging perspective
Authors: Goyal S.K. , Nema P. , Devotta S. 
Published: January 2008

AbstractA concept of an integrated industrial complex encompassing three major industries; viz. sugar, distillery and paper along with a cogeneration plant (generating electricity and process steam required by the industries in the complex) is presented in this article. Molasses and bagasse generated in the sugar industry are proposed to be used by the distillery and paper industry respectively. Surplus bagasse would be used as fuel in cogeneration plant. Sugar, distillery, and paper industries generate high strength wastewater in large volume, which when treated anaerobically produces biogas. This scheme would provide twin advantages of pollution load reduction at low cost coupled with energy production, which will also partially meet the energy requirement of the industrial complex. The entailing benefits would be reduction in fuel consumption and lower air emissions. Low strength wastewater from different processes as well as sewage from industries and townships can be treated in a combined wastewater treatment plant. The treated wastewater can be recycled/reused for industrial as well as for irrigation purposes in the complex and/or nearby industries and agricultural land. © 2008 American Institute of Chemical Engineers Environ Prog, 2008
Free second toe one‐stage‐plasty and transfer for thumb or finger reconstruction

Published: January 2008

AbstractFree second toe transfer has become a popular method for the management of thumb or finger reconstruction. However, this creates an obvious appearance defect. A new operating procedure has been used since 1999. To enlarge the perimeter of the reconstructed thumb, a composite tissue strip flap from the fibular of great toe pedicled with the fibular proper plantar digital artery, combined or not with the island dorsal index finger flap, was inlaid with the second toe at the same time before the reconstruction. A crescent double‐winged dorsal metatarsus flap, connected with second toe, in combination with the partial metatarsal bone, was also used to reconstruct fingers. There were 36 patients in the study group with a follow‐up time of 6 months to 3 years. The thumb and finger reconstructed in this way showed better appearance, with normal caliber and length and without obvious adverse affects. This method has ameliorated the embarrassing appearance of the reconstructed thumb with earlier methods and is a relatively ideal method for thumb or finger reconstruction. © 2008 Wiley‐Liss, Inc.

QUANTUM YIELDS FOR ENZYME INACTIVATION AND THE AMINO ACID COMPOSITION OF PROTEINS*
Authors: McLaren A. D. , Hidalgo‐Salvatierra O. 
Published: January 2008

Summary A formula has been derived which as a first approximation, predicts the quantum yields for the inactivation of enzymes. The enzymes can be divided into a group containing cystine and the subtilisins which do not. The formula applied to subtilisin gives good agreement. For some of the enzymes, only cystine needs to be considered in the calculation; for others good agreement is found if contributions from aromatic groups are included. On this basis a quantum yield for tobacco mosaic virus protein is computed as 0.0047 at 2537 Å.The origin of chemically modified histidine in photochemically inactivated lysozyme has yet to be explained.
PHOTOTROPISM*
Authors: Thimann Kenneth V. 
Published: January 2008

Summary Phototropic curvature is seen to varying degrees in all green plants from algae to orchids, and especially in seedlings, where it may assume life‐or‐death importance. It also occurs in a number of fungi. Recent work centers on the photorecptor, its action spectrum, the effector mechanism, and the inter‐relationships with normal growth.The action spectrum for one type of phototropism of the oat seedling appears identical with that for the fungus Phycomyces and lies wholly in the blue and near u.v. It may indicate a carotenoid like lutein or possibly a flavin in non‐aqueous medium. Red light does not cause phototropism but can modify the response to the blue region. By analogy with the very similar phenomenon of geotropism, in which the georeceptor is probably a type of plastid, the photoreceptor is probably a specialized organelle which moves in a light gradient; this may be either one type of plastid or perhaps an unusual crystalline body which we have recently discovered in the oat seedling.The effector mechanism in seedlings, which has been re‐investigated, is the lateral asymmetrical distribution of auxin, the amount of the shaded side becoming increased. Photodestruction of auxin appears to play no essential part. This asymmetrical distribution results from modification of the normal translocation mechanism, which is metabolically controlled. In fungi, however, the effector remains unknown.
U.V.‐INDUCED MITOTIC DELAY IN THE SEA URCHIN EGG*
Authors: Rustad Ronald C. 
Published: January 2008

Summary Quantitative studies on u.v. and X‐ray‐induced mitotic delay in the sea urchin egg have been reviewed in order to discuss the nature of the target and the expression of the delay. U.V.‐induced division delay arises from damage to a single system which is also senstitive to X‐rays. Centrifugation can displace a sensitive cytoplasmic component into the centripetal half of the egg. This component may be of secondary importance, because no delay results from the irradiation of a small portion of the cytoplasm with a u.v. microbeam. The primary target is some component of the mitotic apparatus (chromosomes, centrioles, asters or spindle). The multiplication of centrioles is delayed.Data concerning the u.v. action spectra, photoreactivation, and acridine orange damage additivity are consistent with the view that the primary target is a nucleic acid or nucleoprotein. Protein synthesis is required before the cell can pass through the radiation‐sensitive stage. The mitotic delay involves an inhibition of protein synthesis.
