Polyaniline/ZnO Nanocomposite: A Novel Adsorbent for the Removal of Cr(VI) from Aqueous Solution
In recent years with the rapid economic globalization, pollution by industries and agriculture has increased, which results in decrease in the quality of ground and surface water. Pollution by heavy metals has become a serious health issue worldwide due to their nonbiodegradable and persistent nature. Therefore, extensive research has been done to develop ecofriendly and effective methods for removal of heavy metals, such as chemical precipitation, ion exchange, electrodialysis, membrane filtration, and adsorption. Among these methods, adsorption is the most recognized technique for wastewater treatment due to high-removal efficiency and ease in operation without yielding harmful by-products. Recently, nanocomposites based on biopolymer-grafted synthetic adsorbent have been used in various industrial applications including wastewater treatment. Therefore, the present chapter will be devoted for the removal of toxic heavy metals from wastewater by using bionanocomposite

Random variational-like inclusion and random proximal operator equation for random fuzzy mappings in Banach spaces
In this paper, we introduce and study a random variational-like inclusion and its corresponding random proximal operator equation for random fuzzy mappings. It is established that the random variational-like inclusion problem for random fuzzy mappings is equivalent to a random fixed point problem. We also establish a relationship between random variational-like inclusion and random proximal operator equation for random fuzzy mappings. This equivalence is used to define an iterative algorithm for solving random proximal operator equation for random fuzzy mappings. Through an example, we show that the random Wardrop equilibrium problem is a special case of the random variational-like inclusion problem for random fuzzy mappings
PEMBUATAN TABLET HISAP EKSTRAK ETANOLIK DAUN SAGA (Abrus precatorius L.) DENGAN AMILUM MANIHOT SEBAGAI BAHAN PENGIKAT MENGGUNAKAN METODA GRANULASI BASAH
Daun saga (Abrus precatorius L.) digunakan secara tradisional oleh
masyarakat sebagai obat batuk dan sariawan. Untuk kemudahan penggunaannya
maka dibuat dalam sediaan tablet hisap. Hal yang perlu diperhatikan dalam
sediaan tablet hisap adalah tingkat kekerasannya. Salah satu faktor yang
berpengaruh dalam penentuan tingkat kekerasan tablet adalah bahan pengikat dan
salah satu contoh bahan pengikat adalah Amilum manihot. Penelitian ini bertujuan
untuk mengetahui pengaruh konsentrasi bahan pengikat Amilum manihot tersebut
terhadap sifat fisik tablet hisap.
Tablet hisap dibuat menjadi empat formula dengan konsentrasi bahan
pengikat yang berbeda pada formula I =5,0%, II=7,5%, III=10,0% dan IV=12,5%.
Kemudian granul diuji waktu alir, sudut diam dan pengetapannya. Tablet hisap
diuji sifat fisik meliputi keseragaman bobot, kekerasan, kerapuhan dan waktu
melarut serta uji respon rasa dan uji KLT. Data dianalisis dengan menggunakan
uji statistik Kolmogorov-Smirnov dilanjutkan dengan ANAVA (bila data
terdistribusi normal).
Hasil penelitian menunjukkan bahwa dengan meningkatnya konsentrasi
Amilum manihot menyebabkan semakin cepat waktu alir, sudut diam semakin
kecil dan indeks pengetapan semakin baik. Pada uji fisik tablet juga menunjukkan
bahwa dengan meningkatnya konsentrasi Amilum manihot menyebabkan semakin
besar kekerasan dan semakin kecil kerapuhan tablet. Uji keseragaman bobot
menunjukkan semua formula memenuhi persyaratan. Uji respon rasa tablet hisap
pada formula I menunjukkan hasil persentasi responden paling tinggi yang
menyatakan rasa enak. Uji KLT menunjukkan bahwa kandungan senyawa yang
berkhasiat dalam daun saga yakni flavonoid dan saponin tidak mengalami
kerusakan selama proses pembuatan tablet hisap
An Ishikawa-type Iterative Algorithm for Solving A Generalized Variational Inclusion Problem Involving Difference of Monotone Operators
In this paper, we study a generalized variational inclusion problem involving difference of monotone operators in Hilbert spaces. We established equivalence between the generalized variational inclusion problem and a fixed point problem. We establish an Ishikawa type iterative algorithm for solving a generalized variational inclusion problem involving difference of monotone operators, which is more general than Mann-type iterative algorithm. An existence result as well as a convergence result are proved separately. The problem of this paper is more general than many existing problems in the literature. Several special cases of generalized variational inclusion problem involving difference of monotone operators are also mentioned
TOGAF usage in outsourcing of software development
TOGAF is an Enterprise Architecture framework that provides a method for developing Enterprise Architecture called architecture development method (ADM). The purpose of this paper is whether TOGAF ADM can be used for developing software application architecture. Because the software application architecture is one of the disciplines in application development life cycle, it is important to find out how the enterprise architecture development method can support the application architecture development. Having an open standard that can be used in the application architecture development could help in outsourcing of software development. If ADM could be used for software application architecture development, then we could consider its usability in outsourcing of software development
Retrospective and prospective study of amputation in burn patients in Kashmir
Background: Burn is the coagulation necrosis of tissue caused as a result of application of heat which is categorized depending upon its depth. Amputation in burn patient is widely reported especially in severe burn to enhance survival. Though the number of amputations is low in civilian population but it represents a significantly large economic loss. Objective was to do a retrospective and prospective study of amputation in burn patients in Kashmir.Methods: This study was conducted retrospectively from July 2007 to June 2017 and prospectively from July 2017 to June 2019 in department of plastic and reconstructive surgery, SKIMS, Srinagar. For prospective group the patients were admitted and resuscitated as per the protocol and then shifted to the burn unit. The patients were closely monitored and the procedures like early and delayed amputation were done as needed.Results: We had finally a total of 35 patients with 24 in retrospective and 11 in prospective group. In retrospective group, 9 patients had minor while as 15 had major amputation. Majority of the patients were in the age group of 20-40 years (58.3%). In prospective group, 6 patients had major while as 5 patients had minor amputation. Majority of the patients belonged to the age group of 20-40 years (45.5%).Conclusions: The amputation rate in burn patients is not reassuring in Kashmir with minor or major amputation needed in almost all patients and the most effected age group is the “productive age group” representing a significant economic loss.
Strategizing policy for the learning english as a language in Makassar Indonesia
Teaching and learning becomes central issue in curriculum and instruction. If teaching and learning process runs well, it tends to gain learning achievement as general learning objectives seem easy. This occurs to all subjects including learning English as a foreign language. So, all components in teaching and learning have to function well such as teaching methods and strategies, teaching media and aids. This research was carried out using a review of literature from various sources and analysis was carried out I the form of review to come up with a framework. In this study, one approach would be promoted as teaching approach to motivate students to learn is guided-inquiry learning. Inquiry learning may help teacher to run his teaching and learning process in order to get curriculum objectives and help students to reach and increase their ability by having higher motivation and preferring learning strategies. A frame work of various variables relating to inquiry was proposed and attention should be paid to the process rather than product, quantity rather than quality, and fluency rather than accuracy. Indonesian students failed to learn skills in English including writing skill. Teacher should motivate their students in order to promote their metacognitive skills
Detection Of Malaria Parasites In Human Blood Cells Using Convolutional Neural Network
Malaria is a blood disease caused by the Plasmodium parasite which is transmitted by the bite of the female Anopheles mosquito. The diagnosis of malaria is carried out by a microscopist through examination of human blood cells. Their level of accuracy depends on the quality of the tool, expertise in classifying and counting infected and uninfected parasite cells. The disadvantages of examining this way include the difficulty in making a diagnosis on a large scale and the poor quality of the results. The dataset used in model evaluation is a dataset developed by LHNVBC which contains 27,558 cell image data. The malaria dataset will be processed through data science processing using a Convolutional Neural Network with the ResNet architecture. The model will conduct training on the dataset and then the model will be able to recognize malaria parasites in human blood cells. The model will be trained by optimizing multinomial logistic regression using Stochastic Gradient Descent (SGD) and Nesterov momentum values. The results of training data validation accuracy from model training with 50 epochs were obtained at 96.23% and 97% after being tested on data testing
