Agarwood has been used for its fragrance and medicinal properties in Asian culture for centuries. In recent years, agarwood gains its popularity in the west due to its usage in perfume formulation. Unfortunately its supply not meets the augmentation market demand. This is mostly because of depleting nature agarwood reservoir and lack of induction technique that can produce agarwood consistently in the plantation. In this study, we look into a case where artificial inducing technique successfully produced high quality agarwood. To assure its quality, agarwood chip was analysed by Gas Chromatography for its chemical profiles. Discovered compounds were identified as sesquiterpene group which also had been characterized as major agarwood compound listed on previous studies. Few compounds that are detected such as δ-cadinene (0.20%), jinkoh-eremol (22.09%), epi-α-cadinol (4.74%), agarospirol (3.75%) and others. Soil condition that contributes into this agarwood formation; soil analysis on physical properties, chemical properties and nutrients content of the soil have been analyzed. Based on the findings, soil condition is an important factor to successfully induced high quality agarwood.

Gentiana dahurica Fisch. is a characteristic medicinal plant found in Inner Mongolia, China. To meet the increase in market demand and promote the development of medicinal plant science, we explored the influence of the environment on its distribution and the quantity of its active compounds (loganic acid and 6’-O-β-D-glucosylgentiopicroside) to find suitable cultivation areas for G. dahurica. Based on the geographical distribution of G. dahurica in Inner Mongolia and the ecological factors that affect its growth, identified from the literature and field visits, a boosted regression tree (BRT) was used to model ecologically suitable areas in the region. The relationship between the content of each of active compound in the plant and ecological factors was also established for Inner Mongolia using linear regression. The results showed that elevation and soil type had the most significant influence on the distribution of G. dahurica—their relative contribution was 30.188% and 28.947%, respectively. The factors that had the greatest impact on the distribution of high-quality G. dahurica were annual precipitation, annual mean temperature, and temperature seasonality. The results of BRT and linear regression modeling showed that suitable areas for high-quality G. dahurica included eastern Ordos, southern Baotou, Hohhot, southern Wulanchabu, southern Xilin Gol, and central Chifeng. However, there were no significant correlations between the contents of loganic acid and 6’-O-β-D-glucosylgentiopicroside and the ecological factors. This study explored the influence of the environment on the growth and quantity of active compounds in G. dahurica to provide guidance for coordinating the development of medicinal plant science.

Community service is one of the duties that must be carried out by every lecturer in Higher Education as one aspect of Tri Dharma University. This community service was titled "The Production of F0 Oyster Mushroom Seeds (Pleurotus ostreatus), The Post-Harvest Handling, and The Utilization of Baglog Waste into Compost" which involved two partners. Partner 1 was in Pegajahan Village, Pegajahan Sub-District who experienced problems with the availability of high-quality F0 and F1 seeds and low production in terms of quality and quantity. Partner 2 was in Blok H Village Dolok Masihul Sub-District, Serdang Bedagai Regency who had a lack of knowledge about post-harvest handling and composting from oyster mushroom baglog waste. Solutions offered for both partners were: (1) transfer of knowledge, such as lectures and discussions; (2) training; and (3) mentoring about the cultivation of F0 and F1 oyster mushrooms. Goals and targets of this activity were: (1) the communities or the farmer groups were able to produce and cultivate F0 and F1 oyster mushrooms, so they did not need to buy F0 and F1 seeds from other regions and can fulfill the market demand; and (2) Partner 2 was able to make compost from oyster mushroom baglog waste and various processed food from oyster mushroom to increase their income. The results of this activity have provided benefits to Partner 1 regarding their ability to produce F0 and F1 seeds, ability to process post-harvest oyster mushrooms into several types of food to increase its selling value, and ability to make compost from baglog waste which can be used for plants to overcome environmental pollution and to increase Partner 2’s income.

The mining industry is one of the leading sectors providing economic benefit to the community. However, mining minerals inevitably affect the ecosystem function of the land, thereby reducing ecological services provided to mankind. Soil remediation is done to restore ecological integrity while mitigating degradation processes. Thus, this study was conducted to determine the chemical properties of abandoned mine soil and to determine the effects of oil palm residues on the growth performance of abaca (Hybrid 7) grown in mined soil under nursery conditions. This study was arranged in a completely randomized design (CRD) with five treatments and four replications, namely, T1 - Mined Soil Alone, T2 - Garden Soil Alone, T3 - Mined soil + Oil Palm Sludge, T4 - Mined Soil + Oil Palm Empty Fruit Bunch (EFB) Biochar, T5 – Mined Soil + Oil Palm Vermicast. Chemical analysis of mined soil revealed extreme acidic soil condition, low organic matter, CEC, N, K, and high P content relative to soil nutrient sufficiency criteria. Mined soil contained 0.347 mg/kg Cd and 0.230 mg/kg Pb which are within the tolerable limit of 2.00 mg/ kg for Cd and 300 mg/kg (Pb), respectively. Application of oil palm residues in mined soil can significantly improve the morphology and dry matter yield performance of hybrid 7 abaca seedlings. Plants grown in mined soil amended with oil palm residues were taller, larger pseudostem girth with more and bigger functional leaves, and had a higher survival rate compared to those grown in soil derived from the abandoned mining area. Abaca plants grown with amendments had accumulated higher dry matter. Oil palm residues particularly vermicast has greater potential as soil amendment under degraded mined in Mawab, Davao de Oro.

The article presents the results of research and work related to the implementation of the research and development project POIR.01.01.01-00-0120/17 co-financed by the EU, through the NCBR, entitled: Innovative technology using thermal analysis, TDA, of self-feeding manufacturing of high-quality cast iron to produce new generation, enhanced performance casts. In many foundries, thermal derivative analysis (TDA) is used in addition to chemical analysis to evaluate the physical and chemical properties of an alloy while it is still in the melting furnace or ladle and before it is poured into the mold. This fact makes it possible to improve the metallurgical quality of the alloy by introducing alloying additives, carburizers or modifiers into the furnace as part of the pre-modification or primary or secondary modification in the ladle or when pouring into molds. Foundry machinery (modifier dosing systems and spheroidizing station) is very important in these operations. Only the full synergy of modern equipment with modern technology ensures high quality and repeatability of the casting process. The article mainly discusses the obtained parameters of TDA analysis (with the use of the ITACA system) at different stages of melting and how to improve them by using modern and fully automated dosing systems (Itaca OptiDose, ItacaWire and ItacaStream). Special attention was paid to the minimum temperature of the eutectoid. The change of its value after the modification process, its influence on the quality of the melted metal, a very strong correlation with the number of nuclei and the number of graphite precipitations in the casts were shown.

The nature of chemical heterogeneity in commercial heparin was investigated, and a practical method of characterization and assay of pharmaceutical heparins was developed. One beef-lung (BL) and six hog-mucosal (HM) heparins were fractionated by sequential extraction of their hexadecyl- pyridinium complexes in 1-butanol by aqueous solutions containing successively increasing concentrations of NaCl. This system fractionates heparins larger than 10,000 daltons according to their anionic density. The fractions were characterized by molar ratios of carbohydrate constituents and by their anticoagulant potencies in the APTT test with human plasma. Galactosamine content and the amount of uronate extracted with less than 0.14 M NaCl provided a measure of non-heparin GAG and low-quality heparin. The molar ratios of carbohydrate constituents of equivalent fractions from different HM heparins were similar, and with the exception of one unbleached sample, had equivalent anticoagulant potencies which were linearly related to the square of the anionic density. The BL-heparin was clearly distinguishable from the HM-heparins in that its most abundant fractions were extracted at higher NaCl concentrations, and the systematic variation in anionic density seen with HM- heparins was not evident. The fractions were only about half as potent as the equivalent HM-heparin fractions.A simplified version of the extraction with a two-step partition fractionation was used to measure the percentages of non-heparin GAG and high-quality heparin respectively, and measurements of various molar ratios were used to both characterize the chemical properties of the heparin and its purity. Activation with silica in the APTT test yielded rectilinear semi logarithmic dilution plots whereas ellagic activation yielded curvilinear plots with lower sensitivity.

The technological advancements have not only made humans more civilized but have also caused the micro-organisms to develop several survival strategies via antimicrobial resistance to keep pace. Such highly developed microbial systems have been classified as superbugs, exhibiting Trojan-horse mechanism. This uncertain behaviour in microbes has challenged humans to scour around novel moiety to shield themselves from the detrimental effects. One such natural phenomenon that has drawn the attention of researchers is the metal-microbe interaction where microbes were found to be controlled during their interaction with metals. Fine tuning could bestow them with enhanced physico-chemical properties capable of controlling life-threatening micro-organisms. Nano forms of metals (nanoparticles, quantum dots, polymeric nanostructures) exhibiting medicinal properties have been implied toward biomedical theranostics. This chapter highlights the mechanistic antimicrobial resistance and the containment strategy using various nano assemblage highlighting its fabrication and bio-molecular interaction.
