Heterotrigona Itama Kelulut honey eehydration process to prolong shelf life

Oneofthemainchallengesinthetropicalhoneyindustrysuchaskelulut honey is the naturally occurring high water content in the kelulut honey composi- tion. If water content exceeds 22%, the fermentation process will occur at ambient temperature, spoiling the kelulut honey taste and reducing its shelf life. Therefore, the dehydration process is highly important to reduce the water content to less than 22% to halt the fermentation process in the kelulut honey. Nevertheless, the dehydra- tion process has its own risk, it had been known that prolonged heating at elevated temperature has adverse effects on the quality of kelulut honey. In this study, a dehy- dration process was applied using indirect heating system to achieve a reduction of water content below 22% adhering to MS 2683:2017. The results have shown that for the lowest capacity of 1 kg kelulut honey, a reduction of water content below 22% was achieved in 2 hours while the highest capacity of 30 kg kelulut honey took 15 hours to achieve the reduction of water content below 22%. Finding from this study will benefit the small-scale kelulut breeders to prolong the kelulut honey shelf life via dehydration process

Analysis on the voltage stability on transmission network with PV interconnection

Voltage stability means the ability of the power system network to maintain steady-state voltage value at all buses in the system under normal condition and after being subjected to a disturbance. This research highlights the effect of solar photovoltaic (PV) as the subject of disturbance to the network system as this kind of energy source has emerged towards higher level of integration into the national grid. High penetration of solar PV into the grid may cause several issues of stability and security to the system particularly effecting the normal voltage and line overloading. This research is focused on the simulation of power flow to study the transmission network behavior with and without the solar PV interconnection. To accomplish the research objectives, the network system will be modelled in a software known as Power System Simulator for Engineering (PSSE). The simulation result will be discussed and analyzed using Voltage Stability Indices (VSI) to prove and strengthen the theory behind the literature review

The Effect of Water Bath Temperature during Electrochemical Deposition of Zinc Oxide

Nanostructure Zinc Oxide (ZnO) is widely applied in various fields such as optoelectronics, sensors, transducers and biomedical sciences. Nowadays, there are many methods that can be used to produce ZnO thin film such as electrochemical deposition. This method is a process of converting or forming an oxide layer on the metal surface. The purpose of this research is to study the effect of water temperature on the morphology of ZnO during the electrochemical deposition process. ZnO nanostructures obtained after electrochemical deposition process is carried out at different water temperatures and a constant current density. Electrochemical deposition process was carried out when the water temperature reached 60, 65, 70, 75 and 80oC. During the deposition process, 0.05 M/L zinc nitrate is used as a single electrolyte. The analysis conducted is divided into four categories, namely FESEM, XRD, EDX and UV-Vis. As a result, the suitable water bath temperature for forming the ZnO morphology with an electric current density of 4 mA/cm2 is at 75oC and at this temperature it has a higher value of composition mass where is 0.61 % compare with other temperature. From the UV-Vis analysis, it shows the value of band gap is 2.87 eV when the temperature of water bath was 75oC. Various studies were conducted to produce ZnO nanotubes because it provide different forms of reaction temperature at constant current densities

Bioconversion of novel and renewable agro-industry by-products into a biodegradable poly(3-hydroxybutyrate) by marine Bacillus megaterium UMTKB-1 strain

Agro-industry by-products are abundant in various valuable compounds. Some of these raw materials are considered as a cheaper carbon source for polyhydroxyalkanoate (PHA) production when compared with pure substrates. It is however often a costly affair for industries to recover the residual carbon components. In this study, poly(3-hydroxybutyrate) [P(3HB)] was produced using a marine Bacillus megaterium UMTKB-1 strain from sweetwater, a by-product from cane sugar refining process. The bioconversion was initiated in shaken-flasks and fermenter experiments. Applications of seawater and sweetwater mixture as well as sweetwater only as PHA culture media were investigated. The produced polymer was characterized using Gas Chromatography (GC) and Gel Permeation Chromatography (GPC). P(3HB) accumulation from tested carbon sources ranged from 3 to 49 wt%. The strain could accumulate P(3HB) in saline conditions when minimal salts medium was replaced with seawater and sweetwater. The P(3HB) content was between 7 and 27 wt%. This strain was also able to grow and accumulate up to 14 wt% P(3HB) when sweetwater was the sole PHA biosynthesis medium. The weights of P(3HB) produced was in the range 3-12 × 105 with polydispersity index values ranging from 2.7 to 3.8. The agroindustry by-products have proven to be potential carbon feedstocks for P(3HB) production. The tested strain was able to grow and accumulate P(3HB) in a novel carbon substrate medium, the sweetwater. This by-product could be used as a raw material for P(3HB) production without any pretreatment

Thrombotic and hemorrhagic complications of COVID-19 in adults hospitalized in high-income countries compared with those in adults hospitalized in low- and middle-income countries in an international registry

Background: COVID-19 has been associated with a broad range of thromboembolic, ischemic, and hemorrhagic complications (coagulopathy complications). Most studies have focused on patients with severe disease from high-income countries (HICs). Objectives: The main aims were to compare the frequency of coagulopathy complications in developing countries (low- and middle-income countries [LMICs]) with those in HICs, delineate the frequency across a range of treatment levels, and determine associations with in-hospital mortality. Methods: Adult patients enrolled in an observational, multinational registry, the International Severe Acute Respiratory and Emerging Infections COVID-19 study, between January 1, 2020, and September 15, 2021, met inclusion criteria, including admission to a hospital for laboratory-confirmed, acute COVID-19 and data on complications and survival. The advanced-treatment cohort received care, such as admission to the intensive care unit, mechanical ventilation, or inotropes or vasopressors; the basic-treatment cohort did not receive any of these interventions. Results: The study population included 495,682 patients from 52 countries, with 63% from LMICs and 85% in the basic treatment cohort. The frequency of coagulopathy complications was higher in HICs (0.76%-3.4%) than in LMICs (0.09%-1.22%). Complications were more frequent in the advanced-treatment cohort than in the basic-treatment cohort. Coagulopathy complications were associated with increased in-hospital mortality (odds ratio, 1.58; 95% CI, 1.52-1.64). The increased mortality associated with these complications was higher in LMICs (58.5%) than in HICs (35.4%). After controlling for coagulopathy complications, treatment intensity, and multiple other factors, the mortality was higher among patients in LMICs than among patients in HICs (odds ratio, 1.45; 95% CI, 1.39-1.51). Conclusion: In a large, international registry of patients hospitalized for COVID-19, coagulopathy complications were more frequent in HICs than in LMICs (developing countries). Increased mortality associated with coagulopathy complications was of a greater magnitude among patients in LMICs. Additional research is needed regarding timely diagnosis of and intervention for coagulation derangements associated with COVID-19, particularly for limited-resource settings.</p

Neurological manifestations of COVID-19 in adults and children

Different neurological manifestations of coronavirus disease 2019 (COVID-19) in adults and children and their impact have not been well characterized. We aimed to determine the prevalence of neurological manifestations and in-hospital complications among hospitalized COVID-19 patients and ascertain differences between adults and children. We conducted a prospective multicentre observational study using the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) cohort across 1507 sites worldwide from 30 January 2020 to 25 May 2021. Analyses of neurological manifestations and neurological complications considered unadjusted prevalence estimates for predefined patient subgroups, and adjusted estimates as a function of patient age and time of hospitalization using generalized linear models. Overall, 161 239 patients (158 267 adults; 2972 children) hospitalized with COVID-19 and assessed for neurological manifestations and complications were included. In adults and children, the most frequent neurological manifestations at admission were fatigue (adults: 37.4%; children: 20.4%), altered consciousness (20.9%; 6.8%), myalgia (16.9%; 7.6%), dysgeusia (7.4%; 1.9%), anosmia (6.0%; 2.2%) and seizure (1.1%; 5.2%). In adults, the most frequent in-hospital neurological complications were stroke (1.5%), seizure (1%) and CNS infection (0.2%). Each occurred more frequently in intensive care unit (ICU) than in non-ICU patients. In children, seizure was the only neurological complication to occur more frequently in ICU versus non-ICU (7.1% versus 2.3%, P < 0.001). Stroke prevalence increased with increasing age, while CNS infection and seizure steadily decreased with age. There was a dramatic decrease in stroke over time during the pandemic. Hypertension, chronic neurological disease and the use of extracorporeal membrane oxygenation were associated with increased risk of stroke. Altered consciousness was associated with CNS infection, seizure and stroke. All in-hospital neurological complications were associated with increased odds of death. The likelihood of death rose with increasing age, especially after 25 years of age. In conclusion, adults and children have different neurological manifestations and in-hospital complications associated with COVID-19. Stroke risk increased with increasing age, while CNS infection and seizure risk decreased with age.</p
