Blood glucose regulation using labview Nalini, M Balaji, V Gayathiri, R Lab View PID Controller Artificial Pancreas Glucose Regulation Fuzzy logic Controller Diabetes mellitus (DM), commonly referred to as diabetes, is a group of metabolic diseases in which there are high blood sugar levels over a prolonged period. If not regulate the glucose level then it will cause the serious damage to heart, kidneys, eyes, and nerves. The pancreas produces insulin to absorb the glucose. In type I diabetes the pancreas does not secrete insulin to compensate this artificial pancreas will be used. The artificial pancreas will mimic the function of pancreas it consists of a sensor, controller and insulin pump. The sensor continuously monitors glucose, the amount of insulin required will be calculated using a controller then injected using insulin pump this is the function of the artificial pancreas. The food we take is converted into glucose. So, meal intake will greatly affect the glucose levels, in this paper a closed loop model is developed based on Bergman’s minimal model and meal intake is introduced as a disturbance then the control action is performed using Fuzzy and PID controller using LABVIEW software.  So, from this, if the glucose concentration exceeds/decreases, above/below a certain point necessary control action will be taken.

Epidemiology of rabies Putra, Ketut Santhia Adhy Animal Rabies Virus Epidemiology The occurrence of an outbreak of rabies in Bali as a shock to the people and local governments are instantly becoming the world's attention because of Bali as a world tourism destination. Since the first outbreak in the southern peninsula of Bali in November 2008, rabies quickly spread across the districts/municipality, until July 2015 had spread across 54 subdistricts and 263 villages. The proportion of rabies cases in the subdistricts and villages the highest occurred in 2011 is shown 94.7% and 36.7%, respectively, but its spread dropped dramatically in 2013 only occurred in 23 subdistricts (40.4%) and 38 villages (4,2%), though rabies outbreak back by increasing the number and distribution of rabies cases significantly in 2014, spread over 94 villages even until July 2015 spread over 89 villages. Rabies attacks the various breeds of dogs with the proportion of rabies in the local dogs showed the highest (98.44%), as well as the male dog,  is very significantly higher than female dogs. By age group, the proportion seen in the age group of 1 to 2 years showed the highest (39.9%). Other animals, such as cats, cows, goats, and pigs have also contracted the rabies infected dog bitesthe . The incidence of rabies is endemic tend to look at some of the same villages actively repeated every year, most occur in Bangli district (29 villages), nevertheless for 3 consecutive years there were 58 villages there are no cases of rabies. The increasing number of cases of rabies in Bali due to the increasing cases of dog bites, since May 2008 to July 2015, there were 274 792 cases, an average of 34 349 cases per year, or 95 cases per day, the highest occurred in 2010 (67 021 cases) with the proportion of positive rabies highest (34.92%) as well as attack rate (AR) showed the most high (0.125%). The number of rabies from 2008 to July 2015 as many as 1,157 cases of rabies and the positive opportunities of dog bite cases continue to rise even odds 83.07 times greater than the previous year. The average prevalence in Bali is showed 16.1%, the highest in Karangasem district (26.1%), but the proportion is highest seen in Bangli district (16.94%). The increasing cases of dog bites there seem to be the influence of the season. It is seen that the number of cases of wild dogs bite or semi free-range dogs likely to increase following cycles of dogs breeding season, most occur in the dry season (April to November), except in 2008 most of the rainy season (December to March) were recorded 8 cases. It was concluded that rabies is endemic, the majority occurred in the local wild dog or semi-free-ranging dogs especially in breeding season and never yet vaccinated for rabies.

This research was designed using Research and Development (RD) following a procedure from Borg and Gall. The procedure consisted of preliminary study, planning, learning materials development, expert judgment, and small-scale trial. The third-year research will be continued with book draft revision, a larger scale trial in the Province of Bali, and revision after the trial.  Data were gathered through document study, questionnaire, and observation. The data were analyzed using both quantitative and qualitative descriptions.  Results of data analysis show a development of an integrated theme-based course book. The book draft improved in terms of layout, coloring, and pictures that suit the children’s interest. The children’s responses indicated that they understood well the learning materials contained in the book. The children could also show social competence well like when apologizing and making an excuse. They showed a good character as helping other people. A balance among cognitive, affective and psychomotor aspects are required for character education. It is suggested that a theme-based book for young children should balance the academic and non-academic aspects.

Health related issues among the child labor: A study in Kurnool district of Andhra Pradesh Jhansirani, P. ILO WHO Young Health Labor Child labor is a worldwide phenomenon but more focus is required on developing countries. The policy framework of International Labor Organization (ILO) to eliminate child labor is based on United Nations (UN) Declaration of Fundamental Principles and Rights at work (1998). Over 170 million children worldwide still work in order to sustain their basic needs. Children are future citizens of the Nation and their adequate development is utmost priority of the country. Unfortunately, child labor engulfs children across the world. The world is home to 1.2 billion individuals aged 10-19 years. Many children are “hidden workers” working in homes or in the underground economy. Although the Constitution of India guarantees free and compulsory education to children between the age of 6 to 14 and prohibits employment of children younger than 14 in 18 hazardous occupations, child labor is still prevalent in the informal sectors of the Indian economy. Child labor violates human rights and is in contravention of the International Labor Organization (Article 32, Convention Rights of the Child). About one-third of children of the developing world are failing to complete even 4 years of education. Indian population has more than 17.5 million working children in different industries, and incidentally maximum are in the agricultural sector, leather industry, mining and match-making industries, etc. Scientific and Literature Open Access Publishing 2018-05-10 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://sloap.org/journal/index.php/ijcms/article/view/6 10.31295/ijcms.v1n1.6 International journal of chemical & material sciences; Vol. 1 No. 1 (2018): International Journal of Chemical & Material Sciences; 31-37 2632-9468 eng https://sloap.org/journal/index.php/ijcms/article/view/6/211 Copyright (c) 2018 International journal of chemical & material sciences

Land use and environment physical condition on sedimentation and water discharge of lindu lake watershed Ramlan, - Rahman, Abdul Faisal, - Sutrisno, Muhammad environment physical condition sedimentation water discharge lindu lake watershed Lindu lake sub-watershed has harmed by various human activities which do not pay attention to environmental sustainability principles. This research aims to know the influence of land use area and environment physical condition on sedimentation and water discharge in Lindu lake sub-watersheds. This research uses survey and non-experimental method on 3 rivers which are Langko (P1), Wongkodono (P2), and Kati (P3). The dependent variable in this research is land use area (area of the garden, shrubs, rice field, forest, and settlement) and environment physical condition (catchment area and average annual rainfall) and the independent variables are sedimentations and water discharge. The used statistical analysis is a multiple regression model. The result shows that the wider shrubs area (X2) reduces sedimentation (Y1) and increases water discharge (Y2). Each addition of one shrub unit will decrease sediment in amount of 0,208 mg/L and affects water discharge an amount of  0,258 m3/sec-1 with regression equation Y1 = 185,903 - 0,208X2 – 587,269X8 and Y2 = 6,854 + 0,258 X2 – 71,708 X8. As for the bigger river shape coefficient (X8) so the smaller water discharge average. Hence, each reduction of one river shape coefficient unit will affect water discharge in the amount of 71,708 m3/sec-1. It can be concluded that significant predictor factor on sedimentation and water discharge are shrubs and river shape coefficient.

Utilization of Durian Durio Zibethinus seed flour and Kelakai Stenochlaena palustris leaf flour formulation as feed for Nile Tilapia Oreochromis niloticus Bakrie, Restu Sulistiyarto, Bambang durian seed growth fish Kelakai leaf Nile tilapia Small-scale fish farmers have financial limitations to buy expensive commercial pellets to meet fish feed needs. Therefore, it is necessary to find alternative feeds that are cheap and able to support fish growth. Durian seeds (Durio Zibethinus) and Kelakai leaves (Stenochlaena palustris) are potential plant materials for additional fish feed which are abundant in Central Kalimantan Province. This study aims to determine whether additional feed formulations made from durian seed meal andelakai leaf meal can provide significant growth in tilapia (Oreochromis niloticus) rearing. The study used an experimental approach with a completely randomized design (CRD) with 3 treatments and 3 replications. The feed formulation is a mixture of pellets with 95% durian seed meal and 5% melakai leaf meal. Additional feeding is based on the following treatment: Treatment A, given commercial feed made by the factory brand MS prima Feed 1000 as much as 5% of the total weight of the fish kept, Treatment B: given formulated feed (90% pellets + 10% durian seed flour and kelakai leaf flour) as much as 5% of the total weight per day, Treatment C: given formulated feed (95% pellets + 5% mixture of durian seed flour and kelakai leaf flour) as much as 5% of the total fish weight per day. The results showed that the feeding of pellet formulations with durian seed flour and kelakai leaf flour as much as 10 % of body weight per day resulted in the highest growth in length and weight of fish.  Thus durian seed flour and Kelakai leaf flour can be used as additional feed for Nile tilapia to help increase fish growth and reduce fish feed costs.

The main properties of the catalytic reforming catalyst Khurmamatov, Abdugaffor M Mirzayev, Navruzbek A Jurayev, Abdulaziz I aerodynamics catalyst dust flowability humidity hygroscopicity stickiness wettability The article presents the results of adhesion, flowability, hygroscopicity, and wettability of RG-482, 582-1.2 catalyst dust under laboratory conditions. It is determined that the smaller the particle size, the easier they stick to the surface of the apparatus. The stickiness of dust was determined by the size of the solid particles of catalyst dust. In the course of the experiments, it was also proved that this catalyst dust is not sticky, this is because the catalyst dust mainly contains fine solid particles, a two-stage efficient process line for cleaning atmospheric air from fine solid particles was proposed.

Study of magnetization of ferrite with Rare Earth and Ca substitutions Wendri, N Suharta, Wayan Gede co-precipitation ferrite magnetization x-ray diffraction This research synthesized nano-ferrite with Rare Earth substitution using the co-precipitation method. The main goal was to produce nanometer-sized RE/Ca-(Fe3O4) ferrite utilizing sand as the primary raw material. This research also sought to generate public interest in natural resources to maximize their benefits. Sand is abundantly available in Indonesia and is commonly used in the production of concrete, bricks, and roads. To obtain nanometer-scale particles, the co-precipitation method was employed in this study. Initially, iron sand was dissolved in HCl, stirred until homogeneous, filtered and NH4OH was added. The mixture was then precipitated, filtered and washed through a repetitive process until the nano-ferrite particles were obtained. To enhance the magnetic properties, rare earth elements (RE) were introduced during the ferrite formation. The results of FTIR characterization revealed absorbance at 1000, 1400, 1600 and 3400 cm-1, indicating vibrations caused by stretching vibrations of the metal-oxygen tetrahedral band, stretching and HOH vibrations of anti-symmetrical NO stretching vibrations arising from the nitrate group still present in the sample. XRD characterization demonstrated a spectrum predominantly composed of RE/Ca-(Fe3O4) with a purity exceeding 90%, along with the detection of SiO2 impurities. Substitution of Gd, GdNd, and Nd results in an increase in lattice constant values for the a, and b-axis, however, decrease for c-axis sequentially. Also, the substitution of Gd, GdNd, and Nd results in an increase in the coercivity and remanence magnetization values sequentially. The average particle size obtained was 150 nm.

Spatial distribution of mercury pollution in the Mempawah River Watershed, West Kalimantan – Indonesia Aji, Tri Bayu Setiawan, Yudi Abidin, Zaenal Tarno, Slamet Mempawah River mercury pollution mercury pollution distribution Watershed (DAS) Mempawah River Basin (DAS) is a water resource for the people of Mempawah and Landak Regencies. The community uses the Mempawah River as the main medium for agricultural needs, plantations, and the rearing of fish for consumption. Awareness of health that comes from water with its various uses, there has been consumer anxiety when consuming air along with agricultural and fishery products that are relevant to water use in the Mempawah watershed. This phenomenon occurs because the water resources of this watershed area have been polluted by mercury as a result of unlicensed gold mining activities in its spatial extent. This research was conducted to analyze the level of mercury pollution in the river basin, due to illegal gold mining activities. The method applied was purposive sampling, through 29 water sample points located in the upstream, middle and downstream. The sample results were explained using the Atomic Absorption Spectroscopy (AAS) tool. Then, from a spatial perspective, the location of PETI activities was analyzed spatially using Spatial Dynamic Modeling Geographical Information System software with kriging interpolation techniques, to predict the distribution of mercury pollution. The results of the research show that in the middle part of the Mempawah watershed, there is mercury pollution from 0.0023mg/lt to 0.0083 mg/l and has exceeded the threshold determined by PP No. 22 of 2021. The upstream and downstream parts of the Mempawah watershed are not polluted by mercury, because the PETI activity point is only in the middle part of the Mempawah watershed. These findings provide suggestions that the allocation of Mempawah River water as the sole raw material for corporate entities and its use for growing fish communities should be more closely monitored, to avoid danger, due to the chain of heavy metal contamination in the form of Mercury.

Response surface methodology for the production of a filter membrane from the combination of sand, PET and salt as a pore-forming agent: Application to the filtration of wastewater from septic tanks Minkla, Nathalie Laure Tchuisseu Atchana, Jeanne Bagamla, Wangmene Djonga, Paul Nestor Djomou Deramne, Rosellyne Serewane Tchatchueng, Jean Bosco composite material experimental design plan plastic waste polyethene terephthalate porogen properties Plastic waste is increasing every day due to urbanization, population growth and in turn, pollutes the environment. These wastes are considered to be a big problem due to their very low biodegradability and presence in large quantities. A large amount of plastic which is being brought by human activities is discarded or burned which leads to the contamination of the environment and air. Therefore, finding alternative methods of disposing of waste by using kind approaches is becoming a major research issue. In this research, polyethene terephthalate waste is used as a binder by burning and mixing with sand and sodium carbonate to investigate the possibility of producing composite material with a plastic sand filter and study the effect of sand, polyethene terephthalate waste and porogen with different design mix ratio on the properties of the product. An experimental design plan was adopted to formulate the materials. To fabricate this material, the melt moulding/particulate leaching technique was used, in which the components are mixed in their respective proportions, moulded, melted and afterwards leached to remove the porogen. We obtained an optimum of 31.0711% porosity for the optimum mixture containing proportions of 0.5, 0.25 and 0.25 plastic sand and porogen respectively. An improved melt/moulding particulate leaching technique was used to improve the permeability and reduce pore sizes of the optimum. This technique involved using a saturated solution of porogen instead of using the porogen in particulate form. The microbial cut-off efficacy of the material was evaluated, in which microbiological analyses were used to enumerate the number of microbes in a lake water sample before and after filtration through the porous material. The results of viable cell counting showed that the material eliminated 92.6% of the water microbes analysed.

Evaluating sustainability: A review of recycling technologies of spent lithium-ion batteries Shehzada, Muhammad Aamir Ali Kanwal, Aneeqa Gul, Aiman Ehsan, Zainab Direct Reuse Electrochemical Processes Hydrometallurgical Recycling Li-Ion Battery Disassembly Lithium-Ion Battery Pyrometallurgical Processes The lithium-ion battery business has grown significantly over the last eight years, with lithium recycling playing an important role in this expansion. The organizations rely on lithium, a key component of lithium-ion batteries, which is derived from natural minerals and brines. However, the sophisticated and energy-intensive procedures required for lithium extraction use a huge aggregate of energy. Lithium usage poured by 18% between 2018 and 2019, indicating the depletion is inevitable. This has led to the development of various lithium recycling methods, including pyrometallurgy, hydrometallurgy, and electrochemical extraction. Despite increased interest in lithium recycling, less than 1% of lithium is presently recycled. Lithium-ion batteries are classified into several varieties, including lithium carbonate, lithium hydroxide, lithium metal, butyl lithium, and lithium specialty batteries. The applications section focuses on their use in transferrable strategies, rechargeable cars, and grid-energy packing structures. This study concludes by emphasizing the accumulative petition for lithium-ion batteries as well as the need for improvements in enactment, affordability, and safety.

An Idea for Extracting Sub-E–K Diagrams of Different Materials from a Representative Composite E–K Diagram, and Extracting Information from Time-Resolved E–K–t Plots Molkhasi, Mrhrvarz : Angle-Ressoved Photoemission Spectroscopy, Brillouin Zone, Reaction Dynamics Chemical reactions can induce significant changes in the electronic structure of materials, leading to alterations in their electrical conductivity and magnetic properties. In this article, we explore the idea that a three-dimensional Energy–Wave Vector–Time (E–K–t) diagram – essentially a time-resolved band structure – can reveal valuable information about how a material’s electronic structure evolves during a reaction. By mapping the occupied electronic states in energy € vs. crystal momentum (k) over time (t), one can follow the electrons involved in bonding changes in real time. We discuss how such dynamic E–K–t analysis sheds light on the speed, intermediates, and extent of chemical reactions, and we introduce the concept of “reaction noise” to describe fluctuations in a material’s electronic and magnetic behavior caused by ongoing reactions. This approach provides a new perspective for understanding reaction mechanisms, with potential applications in improving material performance (e.g., conductivity and magnetism) and in developing sensors to detect reaction-induced changes. We support these ideas with recent findings in ultrafast spectroscopy and operando measurements from the literature. Finally, a comprehensive reference list of 8–10 relevant studies (from journals such as Nature, Science, RSC, IEEE, etc.) is provided to situate this work in the context of current scientific research.

Electronic Structure and Visible-Light Response of a Phosphonate-Coordinated Tungsten Oxide (WO3) Model: A First-Principles Study Kabengele, Carlos N Kasiama, Giresse N Inkoto, Clement L Tshibangu, Damien S-T Ngbolua, Koto-Te-Nyiwa Mpiana, Pius T Tshilanda, Dorothée D Tungsten phosphonate; Electronic structure; Visible-light photocatalysis; Density functional theory The rational design of visible-light-active photocatalysts requires a detailed understanding of how local coordination environments modulate the electronic structure and key photocatalytic descriptors. In this work, we present a first-principles investigation of the electronic structure and optical properties of a tungsten–phosphonate metal–organic framework model using density functional theory. A minimal W–phosphonate cluster, consisting of a WO? unit coordinated by phosphonate groups, is adopted to capture the essential features of the W–O–P motif while maintaining computational tractability. Electronic structure calculations performed at the PBE level reveal a semiconducting character with a valence band dominated by ligand-derived O 2p states and a conduction band primarily composed of W 5d orbitals, indicative of ligand-to-metal charge transfer (LMCT) excitations. Hybrid HSE06 calculations yield an improved band gap of 1.92 eV and enable an accurate alignment of band edges with respect to the vacuum level and water redox potentials. The resulting band positions indicate a strong thermodynamic driving force for the hydrogen evolution reaction, while oxygen evolution is found to be marginally accessible. Time-dependent DFT calculations further demonstrate pronounced visible-light absorption, with an intense band centered at approximately 545 nm originating from LMCT transitions. Overall, this study elucidates the electronic and optical consequences of phosphonate coordination on tungsten-based frameworks and provides atomistic insights relevant for the rational design of visible-light-responsive photocatalysts.  Scientific and Literature Open Access Publishing 2026-04-24 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article https://sloap.org/journal/index.php/ijcms/article/view/2470 International journal of chemical & material sciences; Vol. 9 No. 1 (2026): International Journal of Chemical & Material Sciences 2632-9468 10.21744/ijcms.v9n1.2026 Copyright (c) 2026 International journal of chemical & material sciences http://creativecommons.org/licenses/by-nc-nd/4.0
