Abstract
Chickpea (Cicer arietinum) is a cool season grain legume experiencing a severe yield loss during heat stress due to the intensifying climate changes and its associated gradual increase of mean temperature. Hence, understanding the genetic architecture regulating heat stress tolerance has emerged as an important trait to be addressed for enhancing yield and productivity of chickpea under heat stress. The present study is intended to identify the major genomic region governing heat stress tolerance in chickpea. For this, an integrated genomics-assisted breeding strategy involving NGS-based high-resolution QTL-seq assay, QTL region-specific association analysis and molecular haplotyping was deployed in a population and a diversity panel belonging to 206 mapping individuals and 217 germplasm accessions of chickpea, respectively. This combinatorial strategy delineated a major 156.8 kb QTL genomic region (CaqHT6.1) which is subsequently being narrowed-down to a functional candidate gene CaHSFA5 and its natural alleles associated strongly with heat stress tolerance in chickpea. Superior natural alleles and haplotypes delineated from the CaHSFA5 gene have functional significance in regulating heat stress tolerance in chickpea. Various experimentation including histochemical staining, in silico interaction studies along with differential expression profiling of CaHSFA5 and ROS scavenging genes suggest a cross talk between CaHSFA5 with ROS homeostasis pertaining to heat stress tolerance in chickpea. The salient outcomes obtained here can have potential to accelerate multiple translational genomic analysis including marker-assisted breeding and gene editing in order to develop high-yielding heat stress tolerant chickpea varieties.

Published: April 2023

Abstract
Serious environmental issues might be associated with Methylene Blue(MB) contaminated wastewaters as this synthetic dye is environmentally persistent, toxic, carcinogenic and mutagenic. Crushed-raw Walnut shell(WS) biosorption process provides an effective treatment method. Although with an increase in the specific surface area of the fine adsorbent particles higher efficiency in dye removal could be expected, the comminution energy will simultaneously increase. Consequently, we used a developed Bond-grindability-test, which measures the amount of energy required for comminution, to estimate energy consumption. In addition to adsorbent particle size(course/moderate/fine), two affective parameters of adsorbent to dye ratio and adsorbent dosage, were considered. According to the central composite design-circumscribed, 33 experiments were planned in three groups associated with each size ranges. The results of FTIR spectroscopy confirmed that MB molecules interact with WS functional groups as shifts in the spectrum of treated vs raw WS particles were observed. The Bond-work-index estimated as 564 kWh/t, revealing the standard WS comminution energy. The formation of extended cracks on the fine particles’ surface, due to significant required crushing energy, provided a porous medium for multilayer coatings, validated the compatibility of the Freundlich model for this category. The maximum adsorption efficiency for course particles was over 96% corresponding to 4.61 g/L of WS and 108.58 mg/L of MB. Accordingly, the energy consumption for each mg of adsorbed dye was 7.65 Joules. The removal efficiency of moderate to fine particles depended only on the adsorbent to dye ratio (i.e., 30.5 ~ 34.8 and 31.6 ~ 37.4 g/g, respectively, to achieve maximum MB removal efficiency).

Published: April 2023

Abstract
With the continuous prevalence of wireless sensor network (WSN) applications in the recent days, localization of sensor nodes became an important aspect in research in terms of its accuracy, communication overhead and computational complexity. Localization plays an important role in location sensitive applications like object tracking, nuclear attacks, biological attacks, fire detection, traffic monitoring systems, intruder detections, and finding survivors in post-disasters, etc. The objective of localization is to identify the coordinates of target nodes using information provided by anchor nodes. Precision improvement of the sensor node positions is a key issue for an effective data transmission between sensor nodes and save the node’s energy as well as enhance the network lifetime. In this article, a cost-effective localization algorithm with minimal number of anchor nodes is proposed that uses nature inspired optimization techniques to enhance the localization accuracy compared to the state-of-the-art localization algorithms. The performance metrics considered for simulations and comparison with the existing algorithms include average localization accuracy, communication range, and the number of anchor nodes. The simulation results prove that the proposed gaussian-newton localization through multilateration algorithm (GNLMA) enhances the mean localization accuracy to 92.8% and the range measurement error is limited to 1.22meters. Depending on the communication range of sensor nodes, the average localization accuracy is achieved up to 94.4% using the proposed GNLMA.

Abstract
Objective: To describe and explore the clinical characteristics and associated factors of growth in children after kidney transplantation (KT).
Method: Retrospective study was performed on the clinical data of 111 children who underwent allogeneic KT and met the inclusion criteria (provided by Guangzhou Women and Children’s Medical Center and the Sun Yat-sen University First Affiliated Hospital). Catch-up growth was defined as present if the increment of height standard deviation score (∆Ht-SDS) was ≥0.5 per year. Described the clinical characteristics and compared possible associated factors between children with catch-up growth and no catch-up growth groups.
Result: The median age at KT was 9(6,12) years, and 54.1% (60/111) are females. Mean height-SDS before KT was -2.14±1.29, 55.9% (62/111) showed growth retardation. Catch-up growth within the first years post-KT was present in 47.7% (53/111) recipients, the mean ∆Ht-SDS was 0.53±0.71. The Ht-SDS before KT was positively associated with last follow-up Ht-SDS (R=0.78, P<0.001). The baseline Ht-SDS, transplantation age, serum creatinine, and GC dose were significantly lower in the chase group (all P≤0.05), multivariate logistic regression analysis indicated that lower baseline Ht-SDS and serum creatinine were the protect factors for catch-up growth on the 1st year of post-transplantation (OR=0.62, 0.97, respectively, P<0.05). The last follow-up Ht-SDS affected by baseline Ht-SDS and ∆Ht-SDS. HtSDS was no statistical difference among different age groups (patient age at KT: <6years,6-9 years,9-12years,>12years), but ∆Ht-SDS showed significant difference between groups (0.74±0.80, 0.82±0.73, 0.28±0.67, 0.32±0.47, respectively, P<0.05). Younger Children showed significant catch-up rate after KT(<9years:68%,>9years:31%), however the ∆Ht-SDS was decrease in the second year (P<0.05).
Conclusion: Growth assessment and management should be performed in any pediatric KT recipients. Even in younger children with more catch-up potential, ∆Ht-SDS decreased significantly at second year, growth continues to be suboptimal after KT. Given that baseline ∆Ht-SDS is a significantly associated factor, it is important for children with severe growth retardation need early identification and plan interventions in terms of growth improvement. We expected the children recipients achieved the ideal target height of post-transplantation.

Abstract
In the past decade, topological quantum materials have attracted enormous research efforts in both physics and materials science. However, despite increasing number of discovered topological quantum materials, recent high throughput computations also predicted a majority of topologically trivial materials at the Fermi level. Do all the topologically trivial materials behave identically or are there clear distinct classes of behavior? Topologically trivial insulators can be first classified into two types: atomic insulators (AIs) and obstructed atomic insulators (OAIs), depending on whether the Wannier charge centers are localized or not at spatial positions occupied by atoms. Interestingly, an OAI can possess unusual properties such as surface states along certain crystalline surfaces. Although required by the bulk OAI nature, these surface states do not necessarily cross the entire bulk gap, as they would do in a topological insulator (TI). However, they advantageously appear in materials with much larger bulk energy gap than TIs, which makes them more attractive for potential applications. Here we experimentally and theoretically show that a well-known crystal, silicon (Si) is a model OAI, which naturally explains some of Si’s unusual properties such as its famous (111) surface states. On this surface, using angle resolved photoemission spectroscopy (ARPES), we reveal sharp quasi-1D massive Dirac line dispersions from two kinds of atomic chains due to the (2×1) surface reconstruction. We also observe, using scanning tunneling microscopy/spectroscopy (STM/STS), topological solitons at the interface of the two atomic chains. Remarkably, we show that the different chain domains can be reversibly switched at the nanometer scale, suggesting the application potential in ultra-high density storage devices.
Guarding a Non-Maneuverable TranslatingLine with an Attached Defender
Authors: Das Goutam , Dorothy Michael , Bell Zachary I. , Shishika Daigo 
Published: April 2023

Abstract
In this paper we consider a target-guarding differential game where the defender must protect a linearly translating line segment by intercepting an attacker who tries to reach it. In contrast to common target-guarding problems, we assume that the defender is attached to the target and moves along. This assumption affects the defender’s maximum speed in an inertial frame, which depends on the target’s direction of motion. Zero-sum differential game of degree for both the attacker-win and defender-win scenarios are studied. The payoff is defined as the distance between the two agents at the time of game termination. We derive the equilibrium strategies and the Value function by leveraging the solution for the infinite-length target scenario. The zero-level set of this Value function provides the barrier surface that divides the state space into defender-win and attacker-win regions. We present simulation results to demonstrate the theoretical results.

Abstract
The development of a novel and reliable SERS substrate for surface corrosion analysis of bronze relics is an exciting research topic in cultural relic protection. The present work developed a high-performance surface-enhanced Raman scattering (SERS) substrate based on Ag/ZIF-8/PAN nanofibers. ZIF-8 nanocrystals induced the in-situ growth of silver nanoparticles, and the substrate was tested in the surface corrosion analysis of bronze relics. The porous structure and active centers on ZIF-8 coated on PAN nanofibers assured the in-situ growth of silver nanoparticles. Simultaneously, the adsorption of harmful rust-alkaline copper chloride was enhanced on the surface of bronze relics. The deposits induced perturbations in the extensive metal network, which significantly increased the intensity of the Raman characteristic peaks of the test objects. The strength of the signal at 118 cm− 1 of alkaline copper chloride was enhanced from 1094 to 20790 on the surface of bronze. The remarkable SERS performance of the silver nanoparticles with sharp edges reveals that the synergistic impact of ZIF-8 nanocrystals and PAN nanofibers provide a significant number of Raman-enhanced hot spots. These results indicate that MOF-based nanostructures provide a new path for improving the shape of silver nanoparticles and promote their applicability in cultural relic protection.

Published: April 2023

Abstract
The various tailing streams of an iron ore processing plant were sampled, characterized and upgraded separately. The characterization results showed that the iron grade and dominant iron ore mineral vary from one stream to another tailing stream of the iron ore processing plant so that the total iron content of Cobber tailing was 22.13%, Rougher 43.09%, Finisher 62%, Cleaner 64.68%, overflow of Cobber tailing hydrocyclones 18.46%, underflow of Cobber tailing hydrocyclones 23.62% and tailing thickener underflow 28.92%. The other characterizations of the various tailing streams including particle size, dry solid tonnage rate, mineralogical and chemical compositions, and magnetic behavior by Davis tube tests were determined. The magnetic upgradation of the Cobber and Rougher tailings were performed by the wet magnetic separation at different magnetic field intensities of 2000, 3500, 5000 and 15000 Gauss. Furthermore, the effect of particle size of the Cobber and Rougher tailings was studied on the magnetic upgradation. A concentrate with the highest iron grade of 61.79% and yield of 52.15% was produced from the Rougher tailing. The results confirmed that the separate stockpiling of various tailing streams is a conscious strategy for the future reprocessing of the iron tailings.

Abstract
L-Ascorbic acid, also known as vitamin C, is a very important antioxidant ingredient and used in many industries. 2-keto-L-gulonic acid (2-KLG) is the main precursor of L-ascorbic acid production and it can be produced from L-sorbose via microbial fermentation or chemical (catalytic) oxidation. While some special strains are used in microbial fermentation, some catalysts are used in chemical oxidation. The aim of this research is to determine the optimum conditions by using the reaction temperature, pH value and time as the variable factors for the production of maximum 2-KLG content with the catalytic oxidation of L-sorbose in the presence of Pt/Al2O3 catalyst with response surface methodology approach. The limit values of variable factors were applied as 40, 50 and 60°C for the temperature; 7, 8 and 9 for the pH value and 3, 6 and 9 h for the time. According to the analyses results, the increasing time and temperature effected the conversion of L-sorbose into the 2-KLG negatively. The optimum conditions as regards the central composite design were determined as 41.30°C for the temperature, 8.23 for the pH and 3.25 h for the reaction time. Under these conditions L-sorbose was converted into 2-KLG with an average yield of 43.70%.

Abstract
Waste materials can be used to optimize bentonite content in compacted clay liners, which can also provide enhanced performance. In this research, the use of sewage sludge & slag- clinker dust and brick dust as replacement for Na bentonite was evaluated. The main composition of the liner mix design was set as beach sand and Na bentonite with a mixing ratio of 3 to 1, respectively, to satisfy the minimum requirements of commonly accepted regulations for liner materials. Waste materials were added as 3%, 6% and 12% by dry weight of the beach sand and bentonite mix. Physicochemical properties, compaction characteristics, compressive strength, volume change behavior and hydraulic conductivity were measured through a series of laboratory tests. The effect of curing was assessed after 1, 7, and 28 days. In addition, microstructural interactions were observed directly and indirectly through Scanning Electron Microscopy, X-ray Diffraction, X-ray Fluorescence and Fourier-transform infrared spectroscopy tests. Results showed that the waste materials have enhanced the mechanical behavior of sand bentonite mixture. The presence of pozzolanic materials provided formation of additional bonds affecting pore volume, decreasing swell potential and hydraulic conductivity even below desired levels. The unconfined compressive strength of all mixture groups significantly increased during early stages of curing time. Overall, the use of waste materials in compacted liners offers an alternative and sustainable solution for recycling and reducing waste and shows their potential as stabilizer materials in landfill applications.

Abstract
Introduction: Treatment adherence is one of the milestones in the care of hypertensive patients, with as potential educational tools new technologies of information and communication. This study aimed to evaluate the add on effect of a digital Cartoon educative video on the therapeutic observance of patients followed up in the General hospital Yaoundé compared to standard of care.
Method: We conducted a randomized simple blind clinical trial at the cardiology unit of the Yaoundé General Hospital, over a 6 months period from 1st March to 30th August 2022. We enrolled 110 patients and randomized them in blocs of 4 creating two groups of 57 and 53, respectively without (group 1) and with (group 2) intervention. Pre-intervention treatment adherence was assessed using the Morisky Medication Adherence Scale (MMAS). In the standard group (G1) we did standard paper based clinical counselling including oral advice and in the intervention group (G2) with did the same and added a digital cartoon video containing exactly the same message with images and audio. The primary outcome was medication adherence after three months.
Results: The mean age in group 1(paper) was 56.65±10.98 years and 56.42±10.46 years in group 2 (paper + video), without any significant difference. The two groups were similar regarding the proportion of females (36.8% in G1 and 49.3% in G2), and the educational levels. According to the Morisky medication adherence scale,before the intervention, the proportions of patients with good, medium and low treatment adherence in group 1 and 2 were respectively 7%, 25.6%, 67.4%, and 5.1%, 43.6%, 51.3%, without any statistical difference. After interventions, the proportion of patients presenting a good observance moved from 7 to 11% in group 1(paper), and 5.1 to 20%in the group 2( paper + video), respectively. The intragroup variation of treatment adherence in the intervention group (before-after) tended to be significant with a p-value = 0.0572, while this p-value was 0.712 in the standard group.
Conclusion: Our results provide an insight on how digital cartoon videos can help to have an add-on effect on treatment adherence of hypertensive patients, with a clinical significance.
A DNA extraction method for nondestructive testing and evaluation of cotton seeds (Gossypium L.)
Authors: Karaca Mehmet , Ince Ayse Gul 
Published: April 2023

Abstract
Kernels of cotton provide lint and linter for textiles, oil and protein for food and feed. Cotton seed is formed following fertilization between an ovule and a pollen grain. The seed coat is maternal in origin, whereas the embryo and attached cotyledonary leaves are hybrids of parental lines. The extraction of genomic DNA from an ungerminated whole, a portion or mixed seeds are prerequisite in genetic and genomic studies of cotton. As far as our knowledge, there is only one method of nondescriptive DNA extraction from ungerminated cotton seeds without affecting the seed germination capability, but it has technical difficulties and requires special equipment. Furthermore, the amount of DNA extracted using the published method is low and, therefore, it is only suitable for routine marker assisted selection studies. In this study, a modified CTAB DNA isolation protocol referred to as the CTAB-LiCl DNA extraction method was developed for single whole cotton seed, a portion of cotton seed and bulked cotton seeds. The CTAB-LiCl DNA extraction method was evaluated in ninety-six individuals of six different cotton cultivars along with two genetic standards of cotton, TM-1 (G. hirsutum L.), Pima 3–79 (G. barbadense L.), and several other plant species of different plant genera. Results revealed that this method produced high quality and amounts of DNA as confirmed by spectrophotometry, agarose gel, restriction enzyme digestion, polymerase chain reaction, and library production for next generation sequencing studies of whole genome bisulfite sequencing. It does not require the use of liquid nitrogen, RNase, proteinase K, or beta-mercaptoethanol and can be completed in approximately 2 h. Small tissues of the chalaza ends of ungerminated cotton seeds could be used to obtain high quality and quantity of DNA ranging from 14 µg to 28 µg without affecting the seeds’ germination ability, allowing marker-assisted selection before planting and flowering.
