Authors:   Dean & Additional Director of Agriculture, Agricultural College and Research Institute,Coimbatore 641003, B.W.X PONNAIYA
Published: October 2023

Silica deposition in plant material is usually studied by examining epidermal peels. These peels are obtained either by working with a razor (Prat, 1932) or by using a macerating fluid like sulphuric acid and potassium dichromate (Suryanarayana and Krishnaswamy 1948; Parry and Smithson, 1958) and mounting them in Canada-balsamphenol mixture. A better method of studying the arrangement of silica deposits in situ is by 'spodograms', which are mounted ashed material on glass slides (Uber, 1940). The evolution of spodograms and the latest methods have been detailed in this paper.
Better approximation for the precision of the number of counts in the histogram test of ADCs
Authors: Francisco André Corrêa Alegria
Published: October 2023

Here one proposes a new analytical expression that can be used to estimate the precision of the estimates made with the histogram test of analog-to-digital converters as a function of the additive noise standard deviation present in the test setup. This can be advantageously used to determine the minimum samples that should be acquired in order to achieve a certain level of precision on the estimates made. A more rigorous choice of the number of samples makes the characterization more efficient and less time consuming.

Published: October 2023

Effluents emerging from unprotected local mining activities pollute the nearby rivers containing aquatic lives. Advent of nanotechnology however, supposedly helps in removal of water contaminants and as well make waste water remediation possible. To this effect, Clarias gariepinus from rivers near mining site at Ijero-Ekiti, Ekiti-State, Nigeria were collected and exposed to 62.5, 125 and 250mg/L suspension of 10nm magnesium hydroxide nanoparticles (MgOHNPs) for 14-days under semi-static conditions. The suspected lead concentration in the river water was estimated using atomic absorption spectrophotometer while the quality of the river water was also examined. Clarias gariepinus collected were sacrificed and alterations in their biochemical and hematological indices were evaluated. The results showed that water sample from river I exhibit highest (0.033ppm) lead concentration while water sample from river III has the lowest (0.006ppm) lead concentration relative to their proximity to the mining site. Besides, the collected fishes demonstrated significant (P<0.05) concentration dependent increase in some biochemical indices and no observable significant alteration in hematologic state of the fishes at tested doses. Hence, results from this study suggest that toxic lead effluent from local mining activities may have elevated lead concentration levels in nearby rivers while exposure to MgOHNPs could evoke alterations in physiological system of the inhabiting aquatic lives.

Examining the influence of foreign language anxiety on organizational strategies and foreign language proficiency in Chinese secondary EFL learners
Authors: Meihong Jiang
Published: October 2023

Academic anxiety is one of the prominent emotions in learning English as a foreign language (EFL), and its impact on foreign language proficiency (FLP) has been extensively documented. However, the mediating effect of cognitive strategies between foreign language anxiety (FLA) and FLP has rarely been explored. In a sample of 524 Chinese secondary school students, the present study investigated the linkage between FLA, organizational strategies, and FLP. Structural equation modelling (SEM) and mediation analysis were conducted, and three findings were identified. First, FLA was negatively correlated with the use of organizational strategies. Second, the negative correlation between FLA and FLP was identified. Third, organizational strategies fully mediated the association between FLA and FLP after controlling for gender and age. Exploring the mediating mechanism between FLA and FLP might help EFL educators take intervention measures to alleviate the negative impact of FLA on foreign language learning. Limitations and directions for future research are discussed.

Authors: Fayomi Omotola Michael  , Akande James Asamu  , Olayemi Ifeoluwa Oluwatosin  , Kalu Chidiebere Raphael
Published: October 2023

The inhibition efficiency and corrosion rate of aluminium were investigated at varying temperatures and immersion time using thiourea complex with an organic ligand at concentrations of 0.20, 0.40, 0.60, 0.80 and 1.00 M. The results showed that an increase in the concentration of the complex thiourea led to an increase in the inhibition efficiency, which was attributed to the availability of the proton moiety of the thiourea lost as electron in acidic media. The inhibition efficiency decreased as the immersion time increased with temperature and the largest decrease observed at 333 K due to the distortion of molecular structure of the complex thiourea at high temperatures. The corrosion rate decreased with an increase in immersion time but increased with temperature, possibly due to inhibitor molecular rearrangement. The activation energy of the suppression process of high-concentration thiourea was found to be higher than that of low-concentration, indicating that the adsorption process was triggered by physical adsorption. The formation of a thin film on the metal surface was due to the presence of complex thiourea acted as a barrier to both energy and mass transport, leading to an increase in the activation energy. The adsorption of the thiourea derivatives complex on aluminum was primarily physisorption. The Langmuir, Flory-Huggins, Tempkin, and Dubinin-Radushkevich adsorption isotherm models were investigated with Langmuir found to be the most fitted model based on high R2 values of the model.

In Ghana, TB remains a substantial healthcare challenge, with an incidence rate of 136 cases per 100,000 people. Anaemia is prevalent among TB patients, impacting their health and recovery. Anaemia can lead to fatigue, weakness, and compromised immunity, all critical concerns for TB patients. This study aims to investigate the prevalence of anaemia among pulmonary TB patients at Weija Gbawe Municipal Hospital in Accra, Ghana. Among the participants, 22.6% were found to have pulmonary TB, with the majority not showing resistance to rifampicin (95.5%), a primary treatment drug. Females had a higher prevalence of TB (53.3%), possibly due to hormonal and social factors. Participants over 66 years had a high prevalence, likely due to weakened immune systems associated with aging. Anaemia was prevalent among participants, especially females, and it was more common among TB patients (68.8%) compared to non-TB patients. Normocytic anaemia was the most common type among TB patients, followed by microcytic anaemia, suggesting potential iron metabolism issues. This study provides valuable insights into the prevalence of anemia among TB patients and the distribution of different types of anaemia in this population. Understanding these factors can aid in better management and treatment of TB patients.

This review paper updates the benefits of using hemp fibre for the production hemp plastic. Traditional fossil-fuel based plastic production emits massive levels of greenhouse gasses, and the material can take hundreds of years to break down. Traditionally, plastics are made from petroleum-based compounds, which release toxic gases into the atmosphere. Petroleum-based plastics and its by-product have a devastating effect on the land, water, and wildlife. Biodegradable plastics are produced using petro-chemicals just like conventional plastics except some additives are included in their manufacturing which helps them in there fast degradation. Hemp plastic is a type of biodegradable plastic made from hemp fibres, which has a sufficiently high cellulose concentration in manufacturing polymers. The resulting material is fully biodegradable and recyclable. It can then be processed into various products, including packaging, consumer goods, automotive parts, and more conventional plastics. Hemp plastic which is 100% biodegradable, can be a better alternative to synthetic plastic. Hemp plastic is also lightweight, with an impressively high density to weight ratio. This makes hemp plastic a potentially good material for making lightweight components in the car and aerospace industry. Conversely, hemp plastic helps to minimize the greenhouse effect. Hemp plastic offers great thermal, UV, and dimensional stability. Some types of hemp plastic are also resistant to flame. Hemp plastic is solely produced using the cellulose extracted from hemp plant and therefore, causes no toxicity during its production.

Kehadiran mahasiswa dalam suatu pembelajaran di kelas seringkali menjadi syarat wajib dalam dunia pendidikan, dan menjadi tolak ukur dalam menilai mahasiswa. Terkadang masih dijumpai praktik curang oleh mahasiswa dalam absensi agar mencapai kehadiran minimal. Dari sisi administrasi, absensi berbasis kertas berpotensi pemborosan dan juga memperpanjang tahapan administrasi karena membutuhkan rekapitulasi manual. Metode yang digunakan dalam penelitian ini adalah pendekatan Deep Learning dengan arsitektur CNN untuk mengenali wajah. Selain gambar wajah, sistem juga akan memvalidasi absensi dengan kesesuaian lokasi dan waktu. Kehadiran mahasiswa dalam proses pembelajaran sangat diperlukan untuk mengetahui jumlah mahasiswa. Penelitian ini dilakukan untuk membuat sebuah sistem pendeteksian wajah dalam mengenali mahasiswa di dalam kelas, kemudian menangkap dan mendeteksi seluruh wajah mahasiswa secara akurat serta melakukan pengujian terhadap sistem, dimana hal ini dilakukan untuk mengetahui sejauh mana sistem dapat bekerja, dalam penerapannya penelitian ini menggunakan algoritma Convolutional Neural Network sebagai metode DeepLearning yang dapat digunakan untuk mengenali dan mengklasifikasi sebuah objek. Sistem ini berhasil mendeteksi 8 dari 10 wajah mahasiswa dan memiliki presentase keakuratan sebesar 80%, dengan jumlah data 300 uji gambar wajah.

Aplikasi chatting telah menjadi media komunikasi digital yang digunakan oleh setiap kalangan, mempermudah manusia dalam mengirim pesan maupun menerima pesan. Pesan-pesan yang disampaikan ada kalanya berupa pesan yang bersifat rahasia sehingga tidak semua pihak dapat melihat pesan tersebut. Namun sering terjadinya kejahatan seperti penyadapan data, pencurian informasi, dan penyalahgunaan data pribadi yang merupakan masalah yang paling ditakuti oleh para pengguna jaringan komunikasi. Maka diperlukan suatu sistem keamanan yang dapat melindungi suatu informasi untuk menyembunyikan atau mengamankan suatu pesan ke dalam bentuk pesan lain. Untuk menyelasikan permasalah tersebut terdapat sebuah pembelajaran tentang kriptografi yang dapat mengenkripsikan pesan atau teks kedalam bentuk chipertext sehingga dapat menyembunyikan pesan asli yang dikirimkan. Tujuan penelitian ini untuk melakukan pengaman data teks pada aplikasi chatting menggunakan metode Modular Multiplication- Based Block Chiper (MMB) dengan mengetahui berapa lama waktu enkripsi sebuah pesan dan untuk mengetahui panjang karakter pesan setelah dienkripsi. Dari pengujian tersebut diperoleh bahwa rata-rata waktu enkripsi dan dekripsi pesan membutuhkan waktu sebesar 1.87 detik. Untuk panjang pesan setelah dienkripsi karakter yang dihasilkan sebanyak 32 Hexadesimal atau 16 karakter chiphertext.

Penyakit Telinga, Hidung, dan Tenggorokan (Otolaryngology) merupakan salah satu penyakit berbahaya karena menyerang beberapa organ manusia yaitu telinga, hidung, dan tenggorokan. Seringkali penyakit THT (Telinga, Hidung, Tenggoro kan) disebabkan oleh infeksi kuman, namun banyak juga yang disebabkan oleh kelainan perkembangan sel tubuh, yang nantinya mempunyai kemungkinan untuk menjadi tumor dan kanker. Penyakit di sekitar hidung, telinga, dan tenggorokan biasanya disebabkan oleh infeksi kuman, tetapi banyak pula yang diakibatkan oleh kelainan perkembangan sel tubuh, yang kemudian menjadi tumor dan kanker. Penderita suatu penyakit biasanya membutuhkan informasi tentang penyakit berdasarkan gejala-gejala yang dialami sebelum memutuskan untuk menemui dokter atau pergi ke rumah sakit. Dalam hal ini diperlukan adanya deteksi dini melalui sistem yang dapat menerima inputan berupa gejala-gejala penyakit yang dialami oleh penderita dan selanjutnya akan memberikan diagnosa penyakit serta penjelasan mengenai penyakit tersebut. Salah satu solusi dari permasalahan ini adalah dengan dibangunnya sistem pakar yang dapat membantu pengguna untuk mendiagnosa penyakit THT secara praktis dan akurat. Sistem pakar untuk mendiagnosa penyakit THT yang dirancang dan diteliti pada penelitian ini menggunakan metode certainty factor. Metode ini dapat mengatasi ketidakpastian dalam pengambilan keputusan berdasarkan gejala-gejala yang dirasakan atau diinputkan oleh user.
