This paper presents the development of a mathematical model for pigment formulations used for screen printing textile inks in order to reproduce the NATO IRR green standard using four highly performant pigments: Hostaperm Yellow H4G (CI 13980), Irgazin Red A2BN (CI 65300), Heliogen Blue (CI 74160), and Lamp Black (CI 77266). In order to study the influence of each pigment on the final CIE L* a* b* parameters, a quadratic mathematical model (Scheffé type) was created and experimentally validated. The model was used and verified for generating pigment compositions for textile inks that reproduce the NATO IRR green. A total of 22 possible solutions were developed and experimentally performed. Studies regarding the reflectance in the visible-near-infrared domain were conducted, ensuring compliance with the standard. The optimal composition of the pigment mixture was 66.55% Hostaperm Yellow H4G, 7.66% Heliogen Blue, 12.01% Irgazin Red A2BN, and 13.78% Irgazin Red A2BN. The mixture was added to textile ink in the proportion of 5% and was applied via serigraphy.

Black Color

Color is of great importance in our India, without color, there is no basis for any object, person, color really tells us the nature of each other. The color or color refers to the color of the substance, red, yellow, blue. Depending on the combination of these, several distinctions of varna can be made. India is a religious country with different beliefs. Manuscripts have a special relationship with religion. Manuscripts are the best means of salvation for our teachers. One of them is the illustrated Jain manuscript Adipuran. The manuscript, which has been composed by Acharya Pushpadanta, depicts the life history of Lord Rishabhdev (the first Tirthankara) through paintings. The presented manuscript is stored in the scripture store of Terapanthiyan, the Digambar Jain big temple of Jaipur. Its clerical 1597 (AD 1540) is Falgun Shukla 13. Its writing work was done by a Brahmin man named Vishnudas and the paintings are made by Harinath Kayastha and his family. This 687-page manuscript has 541 colored illustrations corresponding to the biography of Tirthankara Rishabhdev. Mainly in the picture, the mineral color (made from a mixture of vegetable juices, ie the color made from the bark of clay stone trees, etc.) is the most used. Mainly ocher (red) Hironji (green) Ramaraj (yellow) ink (black) color is mainly used. The four colors used in the manuscript are symbols of Jainism, such as the red color (ocher) represents our inner vision, that is, the Siddha Parmeshti used in Jainism. Those who have attained salvation. Yellow color activates our mind. Green color gives peace. It helps in self-realization. Blue color is absorbent and does not allow the outside effect to go inside. Black color was used for writing in manuscripts. The ink for writing work was made with three methods. हमारे भारतवर्ष में रंग का बहुत महत्व है रंग के बिना किसी भी वस्तु, व्यक्ति का कोई आधार नहीं है सही मायने में रंग ही हमको एक दूसरे के स्वरूप को बताते हैं। वर्ण या रंग का अर्थ पदार्थ की रंगत से है लाल, पीला, नीला। इनके मिश्रण के आधार पर वर्ण के अनेक भेद किये जा सकते हैं। भारतदेश एक धर्म प्रधान देश है जिसमें विभिन्न मान्यतायें हैं। धर्म के साथ पाण्डुलिपियों का विशेष सम्बन्ध है पाण्डुलिपियाँ हमारे गुरूओं की मोक्ष साधना का उत्तम साधन है उनमें से एक है सचित्र जैन पाण्डुलिपि आदिपुराण। जिसकी रचना आचार्य पुष्पदंत ने की है पाण्डुलिपि में भगवान ऋषभदेव (प्रथम तीर्थंकर) के जीवन चरित को चित्रों के माध्यम से दर्शाया गया है। प्रस्तुत पाण्डुलिपि जयपुर के दिगम्बर जैन बड़ा मन्दिर तेरापंथियान के शास्त्र भण्डार में संग्रहित है। इसका लिपिकाल 1597 (ई. सन् 1540) फाल्गुन शुक्ल 13 है। इसका लेखन कार्य विश्नुदास नाम के ब्राह्मण व्यक्ति के द्वारा किया गया और चित्र हरिनाथ कायस्थ और उनके परिवार द्वारा बनाये गये हैं। 687 पृष्ठों की इस पाण्डुलिपि में तीर्थंकर ऋषभदेव के जीवनचरित के अनुरूप 541 रंगीन चित्र हैं। मुख्य रूप से चित्र में खनिज रंग (वनस्पति रसों के मिश्रण से निर्मित अर्थात् मिट्टी पत्थर वृक्षों की छाल आदि से बने रंग) का प्रयोग सर्वाधिक किया गया है। मुख्यतः गेरू (लाल) हिरोंजी (हरा) रामरज (पीला) स्याही (काला) रंग प्रमुख रूप से प्रयोग हुआ है। पाण्डुलिपि में प्रयुक्त चारों रंग जैन धर्म के प्रतीक हैं जैसे कि लाल रंग (गेरू) हमारी आंतरिक दृष्टि यानि कि जैन धर्म में प्रयुक्त सिद्ध परमेष्टी को दर्शाता है। जिन्होंने मोक्ष को प्राप्त कर लिया है। पीला रंग हमारे मन को सक्रिय करता है। हरा रंग शांति देता है। आत्मसाक्षात्कार में सहायक होता है। नीला रंग अवशोषक होता है वह बाहर के प्रभाव को अंदर नहीं जाने देता। काला रंग पाण्डुलिपियों में लेखनकार्य के लिये प्रयोग में लाया जाता था। लेखन कार्य के लिये स्याही तीन विधियों से बनायी जाती थी।

AbstractRed color (A. tricolor) genotypes are an excellent source of pigments, such as betalain (1122.47 ng g−1 FW), β-xanthin (585.22 ng g−1 FW), β-cyanin (624.75 ng g−1 FW), carotenoids (55.55 mg 100 g−1 FW), and antioxidant phytochemicals, such as vitamin C (122.43 mg 100 g−1 FW), TFC (312.64 RE µg g−1 DW), TPC (220.04 GAE µg g−1 DW), TAC (DPPH and ABTS+) (43.81 and 66.59 TEAC µg g−1 DW) compared to green color (A. lividus) genotype. Remarkable phenolic acids, such as salicylic acid, vanillic acid, protocatechuic acid, gallic acid, gentisic acid, β-resorcylic acid, p-hydroxybenzoic acid, syringic acid, ellagic acid, chlorogenic acid, sinapic acids, trans-cinnamic acid, m-coumaric acid, caffeic acid, p-coumaric acid, ferulic acid, and flavonoids, such as rutin, hyperoside, isoquercetin, myricetin, quercetin, apigenin, kaempferol, and catechin were observed in the red color amaranth genotypes, which was much higher compared to the green color amaranth genotype. We newly identified four flavonoids such as quercetin, catechin, myricetin, and apigenin in amaranth. Among the three selected advanced genotypes studied the red color genotype VA13 and VA3 had abundant antioxidant pigments, phytochemicals, phenolic acids, flavonoids, and antioxidant activity could be selected for extracting colorful juice. Correlation study revealed that all antioxidant constituents of red color amaranth had strong antioxidant activity. The present investigation revealed that two red color genotypes had an excellent source of antioxidants that demand detail pharmacological study.

A Au colloid was prepared in a 5 mM HAuCl4 solution through irradiation with a focused infrared femtosecond laser at 800 nm. The Au colloid was characterized by absorption spectra, transmission electron microscopy, and x-ray diffraction analysis. The appearance of absorption peak around 526 nm in the absorption spectra and the wine-red color of sample solution HAuCl4 under focused laser irradiation verified the formation of Au colloid. The solution color changed in the order of yellow → orange → wine-red due to the local formation of Au nanoparticles near the focus. The pulse energy, focus position of laser beam, and solvent composite play important roles in formation, grain size, and stability of the Au colloid. A mechanism for the precipitate of Au nanoparticles was proposed, and a multiphoton process of femtosecond laser was involved.

The present experiment was carried out at the Laboratories of the Department of Horticulture and Biochemistry and Molecular Biology, Bangladesh Agricultural University, Mymensingh during the period from February to April 2019 to study the effect of maturity indices and modified atmosphere packaging (MAP) on the extension of shelf life and quality retention of cherry tomato. The two-factor experiment consisted of three maturity indices viz. (i) Maturity index 1 (M1: Mature green color), (ii) Maturity index 2 (M2: Yellow color), and (iii) Maturity index 3 (M3: Red color) and five postharvest treatments viz. (i) Control (T0), (ii) Low density perforated poly ethylene, LDPPE (T1), (iii) Low density poly ethylene, LDPE (T2), (iv) Low density perforated plastic box, LDPPB (T3), and (v) Low density plastic box, LDPB (T4). The experiment was conducted in completely randomized design with 3 replications. The maximum weight loss (7.77%) was recorded in mature green color fruits (M2) treated with control (T0), while the minimum (3.22) was found in yellow color fruits (M2) treated with LDPPB (T3). The maximum color change was observed from yellow color fruits (M2) with LDPPB (T3) and the minimum was observed from mature green color fruits (M1) treated with control (T0). The maximum TSS content (7.20%) was recorded from yellow color fruits (M2) treated with LDPB (T4), while the minimum (5.67%) was found in mature green color fruits (M1) treated with LDPPB (T3). The highest disease incidence and severity (16.67% and 21.67%, respectively) were recorded in red color fruits (M3) treated with control whereas the lowest disease incidence (1.67%) and severity (2.33%) were found in yellow color fruits (M2) treated with LDPPB. The longest shelf life (25.00 days) was obtained in yellow color fruits (M2) treated with LDPPB (T3) and the shortest shelf life (7.00 days) was observed in red color fruits (M3) treated with control (T0). Thus, yellow color fruits (M2) treated with LDPPB (T3) could be used for the extension of shelf life and quality retention of cherry tomato. Progressive Agriculture 32 (1): 43-59, 2021

Variant of Coleus sp. in Indonesia is very low. Induced mutation by Ethyl Methane Sulphonate (EMS) is able to increase variant of Coleus sp.. EMS is a mutagen that is effective and efficient in causing mutations. In mutation breeding, the high variant usually occurs around LC50 (Lethal Concentration). The objective of this study were (1) to obtain the LC50 value and sensivity of coleus plants, and (2) to evaluate the response of plant growth and to obtain new variance of coleus used soak and drops by EMS application. The experiment was arranged in randomized complete block design with three replications in each coleus. The materials used two Coleus sp. shoot cuttings i.e., C. amboinicus Lour. and C. blumei the purple/green color and the red. The concentration of EMS consisted of 0.00, 0.50, 0.75, 1.00, and 1.25% with application soak method (100 minutes) and drops (3 drops pipette). The results showed that the LC50 value of C. amboinicus Lour. 5.86% (soak). The LC50 value of C. blumei the purple/green color was 0.69% (soak), 0.82% (drops) and the red color 0.29% (drops), 0.89% (drops). C. blumei (the purple/green and red) was higher sensitivity rather than C. amboinicus Lour. There was an interaction between treatments on C. amboinicus Lour. whereas C. blumei (purple/green and red) had no interaction among treatments. C. amboinicus Lour. produced one putative mutant and C. blumei purple/green produced four putative mutants based on the morphology.Keywords: Coleus amboinicus Lour., Coleus blumei, LC50, putative mutan

AbstractUsing multi-color visible lights for independent optogenetic manipulation of multiple neuronal populations offers the ability for sophisticated brain functions and behavior dissection. To mitigate invasive fiber insertion, infrared light excitable upconversion nanoparticles (UCNPs) with deep tissue penetration have been implemented in optogenetics. However, due to the chromatic crosstalk induced by the multiple emission peaks, conventional UCNPs or their mixture cannot independently activate multiple targeted neuronal populations. Here, we report NIR multi-color optogenetics by the well-designed trichromatic UCNPs with excitation-specific luminescence. The blue, green and red color emissions can be separately tuned by switching excitation wavelength to match respective spectral profiles of optogenetic proteins ChR2, C1V1 and ChrimsonR, which enables selective activation of three distinct neuronal populations. Such stimulation with tunable intensity can not only activate distinct neuronal populations selectively, but also achieve transcranial selective modulation of the motion behavior of awake-mice, which opens up a possibility of multi-color upconversion optogenetics.

Active Chemical

The purpose of this study was to qualitatively identify active chemical compounds, namely the content of alkaloids, flavonoids, steroids, triterpenoids, tannins, saponins, and quinones, in the roots, bark and leaves of Jelatang Gajah. The method used is phytochemical screening by identifying using various active compounds in the simplicia of the Jelatang Gajah plant. Flavonoid chemical compounds in this test were not detected, because the solution did not change color. Steroid chemical compounds from 3 (three) times the repetition of the section show a strong / sharp indication value (++) which is indicated by a dark red color change in the phytrate. Triterpenoids were not detected in the three simplicia, the phytrate that had been made did not change color, indicating the presence of triterpenoid compounds. The result of the (+) value in triterpenoid compounds was indicated by a change in green color. Tests for tannin compounds in the elephant nettle plant study found a weak indication (+) in leaf and bark simplicia, while in the simplicia of tannin roots it was not detected (-). Tujuan dari penelitian ini untuk mengidentifikasi secara kualitatif kandungan alkaloid, flavonoid, steroid, triterpenoid, tanin, saponin, dan quinon, pada bagian akar, kulit, dan daun jelatang gajah. Metode yang digunakan yaitu skrining fitokimia dengan mengidentifikasi menggunakan berbagai senyawa aktif pada simplisia tumbuhan Jelatang Gajah. Senyawa kimia flavonoid pada pengujian ini tidak terdeteksi, karena larutan tersebut tidak terjadi perubahan warna.
