Le bas delta du fleuve Sénégal est une zone d’intérêt écologique au regard de la pluralité d’aires protégées qui y sont localisées. Ce milieu, qui se caractérise par la diversité de ses ressources naturelles, développe une très grande vulnérabilité imputable à des causes aussi bien naturelles qu’anthropiques. Depuis quelques décennies, cette fragilité du milieu se répercute sur la mangrove qui assume difficilement ses fonctions écologiques et socioéconomiques. Dès lors, il convient d’analyser la dynamique spatiotemporelle de cet écosystème afin de comprendre les facteurs qui interviennent dans sa dégradation. Dans cette étude, l’objectif a été atteint au moyen de la télédétection à travers le traitement d’images satellitaires Landsat 1980 et 2000, Sentinel 2021 combiné à des travaux de terrains. Cela a permis la réalisation de cartes d’occupation du sol et de cartes de changements. Les résultats démontrent une tendance globale à la hausse de la mangrove avec des espaces couverts qui sont passés de 1 105,82 ha en 1980 à 1 482,32 ha en 2021 malgré une perte de superficies de 166,92 ha sur cette période.

The lower delta of the Senegal River is a zone of ecological interest with regard to the plurality of protected areas that are located. This environment, which is characterized by the diversity of natural resources, develops a very great vulnerability due to natural and anthropic causes. For several decades, this fragility of the environment has had repercussions on the mangrove, which is having difficulty fulfilling its socio-economic and ecological functions. Therefore, it is necessary to analyze the spatiotemporal dynamics of this ecosystem in order to understand the factors involved in its degradation. In this study, this objective was achieved by means of remote sensing through the processing of Landsat 1980 and 2000, Sentinel 2021 satellite images combined with field work. This allowed the realization of land use maps and change maps. The results show an overall increasing trend of the mangrove with areas covered that have increased from 1 105.82ha in 1980 to 1 482.32ha in 2021 despite a loss of area of 166.92 ha over this period.

<em>The fruit of duwet (</em>Syzygium cumini<em> L.) has anthocyanin compounds with some pharmacological effects. Several factors, such as the drying method, determined anthocyanin levels. This study aimed to compare the drying method's effect on anthocyanins' qualitative and quantitative characteristics in duwet fruit. The drying methods tested were (1) fresh fruit (without drying), (2) freeze drying, and (3) sun drying. The sample was macerated with 96% alcohol and 3% citric acid (6:1) and concentrated using a rotary evaporator. The extracts were then qualitatively analyzed with color and TLC tests. Anthocyanin levels were analyzed by the UV-Vis spectrophotometer. </em> <em>The red and green colors of each sample indicated the presence of anthocyanins. Rf values of 0.25; 0.375; 0.5 indicated anthocyanin type, which was cyanidin 3-ramnosil glucoside 5-glucoside, cyanidin 3-glucoside, and petunidin 3,7 diglucoside. The average anthocyanin content in the freeze-drying and sun-drying method were successively 305.406 mg.l<sup>-1 </sup>and 99.0244 mg.l<sup>-1</sup>. The freeze-drying method showed stronger color intensity and higher anthocyanin levels (p&lt;0.05) than sun drying.</em>

Published: February 2023

<p>Perbaikan kandungan nutrisi, daya simpan biji, dan produk olahannya menjadi tujuan perakitan varietas kacang tanah dalam tiga dekade terakhir. Salah satu diantaranya adalah kacang tanah dengan kandungan asam oleat tinggi, yakni rasio oleat/linoleat (O/L) &gt;10 karena produknya memiliki daya simpan 10 kali lebih lama daripada kacang tanah dengan asam oleat normal (rasio O/L &lt;3). Konsumsi kacang tanah tersebut atau produk olahannya juga mampu mengurangi risiko terkena penyakit kardiovaskuler. Seiring dengan meningkatnya kesadaran masyarakat akan pangan sehat dan keperluan untuk bahan baku industri pangan, maka varietas kacang tanah dengan rasio O/L tinggi prospektif untuk dikembangkan di Indonesia. Secara genetik, karakter kandungan asam oleat tinggi dikendalikan oleh dua gen resesif ol1 (AhFad2A) dan ol2 (AhFad2B). Ketersediaan sumber gen asam oleat tinggi yang terbatas, proses perakitan yang tidak mudah, serta biaya yang tidak sedikit menjadi penyebab belum tersedianya varietas tersebut di Indonesia. Oleh karena itu identifikasi dan karakterisasi profil asam lemak aksesi sumber daya genetik kacang tanah, penciptaan keragaman baik melalui persilangan, mutagenesis, maupun pemanfaatan marka molekuler, serta pertukaran materi melalui kerjasama internasional merupakan upaya yang dapat dilakukan dalam perakitan varietas tersebut. Perbedaan kacang tanah berkadar asam oleat tinggi dengan kacang tanah biasa, manfaatnya bagi kesehatan, pewarisan sifat, status, upaya dan prospek pemuliaannya di Indonesia dibahas dalam tulisan ini.<br /><br /></p>

Authors: Sucahyono Didik , Harnowo Didik 
Published: February 2023

Menanam kedelai dengan benih bermutu rendah dapat menyebabkan populasi tanaman di lapangan tidak optimal dan hasilnya rendah. Mutu benih tersebut dapat diperbaiki dengan Matriconditioning, yaitu teknik invigorasi untuk meningkatkan mutu benih yang sudah rendah. Penelitian ini bertujuan untuk mengetahui pengaruh matriconditioning terhadap peningkatan daya tumbuh benih kedelai dan pengaruh perlakuan pupuk hayati yang diintegrasikan bersama matriconditionong terhadap pertumbuhan tanaman dan hasil biji tiga varietas kedelai. Penelitian dilaksanakan di rumah kaca Balitkabi Malang dan di Ngawi Jawa Timur pada MK I tahun 2015 menggunakan rancangan petak terpisah tiga ulangan. Petak utama adalah varietas kedelai yang terdiri atas: 1) Grobogan, 2) Wilis, dan 3) Tanggamus. Anak petak adalah perlakuan matriconditioning benih, yang terdiri atas : 1) Tanpa matriconditioning dan tanpa pupuk hayati, 2) Matriconditioning, 3) Pupuk hayati Iletrisoy, 4) Pupuk hayati Iletrisoy + pelarut P, 5) Matriconditioning + Iletrisoy + pelarut P. Setiap perlakuan ditanam pada petak berukuran 4 m x 5 m, jarak tanam 40 x 15 cm, dua tanaman per lubang. Matrikondisioning benih menggunakan serbuk arang lembab dengan perbandingan 9 benih : 6 serbuk arang : 7 air, selama 12 jam, baik dilakukan sendiri maupun bersamaan dengan pupuk hayati (Iletrisoy). Hasil penelitian menunjukkan tidak terdapat interaksi antara varietas dan teknik matriconditioning pada semua peubah yang diamati. Matriconditioning mampu meningkatkan daya tumbuh benih kedelai berukuran biji kecil, sedang, maupun besar dari 76% menjadi 84% bila disertai dengan penggunaan pupuk hayati Iletrisoy dan bakteri pelarut P. Pupuk hayati Iletrisoy yang dicampur dengan bakteri pelarut P dan diaplikasikan bersamaan dengan matriconditioning pada benih kedelai dapat memperbaiki pertumbuhan tanaman di lapangan, tetapi belum mampu meningkatkan hasil kedelai dibanding tanpa matriconditioning. Pupuk hayati Iletrisoy dan bakteri pelarut P dapat diaplikasikan secara bersamaan dengan matriconditioning.<br /><br />

<p align="center"><strong>ABSTRAK</strong></p><p>Kebutuhan beras di Indonesia terus meningkat disebabkan jumlah penduduk terus bertambah, kebutuhan energi individu meningkat, dan keinginan menjadi lumbung pangan dunia. Sementara terjadi kompetisi penggunaan lahan dan penurunan kualitas lahan. Perubahan iklim global menyebabkan meluasnya daerah yang terimbas intrusi air laut, sehingga terjadi penurunan produktivitas padi, dan biaya input produksi lebih tinggi. Tanah salin adalah tanah yang mempunyai kandungan natrium berada di atas ambang batas kritis atau ambang batas toleransi tanaman. Berdasarkan nilai daya hantar listrik (DHL), dan kadar natrium (Na) dalam tanah, tanah salin dibagi menjadi 5 (lima) kategori, yakni (1) sangat rendah, (2) rendah, (3) sedang, (4) tinggi, dan (5) sangat tinggi. Peningkatan salinitas terjadi pada musim kemarau untuk kondisi daerah dengan curah hujan rendah, dekat pantai, input air irigasi yang mengandung garam, evaporasi dan evapotranspirasi lebih tinggi dibandingkan presipitasi/curah hujan, lahan sawah yang air irigasinya tercemar limbah pabrik berkadar garam tinggi, keadaan topografi, kerapatan irigasi aktif, bencana alam seperti tsunami, dan tanah yang bahan induknya tersusun dari deposit garam. Padi merupakan tanaman yang sensitif terhadap salinitas, tetapi termasuk tanaman yang direkomendasikan untuk dibudidayakan di lahan salin. Salinitas menurunkan kapasitas produksi tanaman akibat (a) tekanan osmotik tanaman yang rendah, (b) kandungan hara N, P, K, dan Ca yang rendah, (c) kandungan Na dan pH yang tinggi, (d) keracunan Al dan Fe, dan (e) degradasi khlorofil. Respon tanaman terhadap salinitas dipengaruhi oleh lingkungan tumbuh dan indeks toleransi tanaman. Pemanfaatan lahan salin untuk peningkatan produksi padi memerlukan teknologi pengelolaan hara dan tanaman. Teknologi pengelolaan hara meliputi (1) ameliorasi menggunakan kapur pertanian, pupuk kandang, kompos, dan bahan organik, dan (2) penggunaan bahan pembenah tanah seperti mulsa, gipsum, SP-50, fosfat alam, dan abu sekam padi. Sedangkan pengelolaan tanaman yang diperlukan adalah (a) penggunaan padi varietas unggul toleran salin, dan (2) pengaturan waktu tanam.</p><p> </p>

Published: February 2023

Abstract
In this paper, a fusion clustering radar signal sorting algorithm is proposed to overcome the shortcoming of the traditional K-means clustering sorting algorithm, which is sensitive to the initial clustering center and easy to fall into a local optimal solution. The improved algorithm combines K-means clustering algorithm and cuckoo search, to reduce the dependence on the initial clustering center and avoid falling into local optimum. Further, a new definition method of fitness function and a new adjustment mechanism of discovery probability are proposed, and sine and cosine guidance are introduced in the process of location updating. The number of clusters is proposed to be adjusted adaptively according to the distance between classes, and the initial cluster center is determined by the data field. Implementation results show that the sorting accuracy of the new algorithm is 96.6%, which is 54% higher than that of the traditional K-means clustering. Compared with PSO-Kmeans, the accuracy is improved by 22%, and the convergence time is reduced by 10 seconds on average.
Novel Designs of Cytotoxic T Cell Assays for Point-of-Care and Laboratory measurements of related Host specific Adaptive Responses to Pathogens and Vaccines
Authors: WAYENGERA Misaki 
Published: February 2023

Abstract
Background
The rapid evolution of the global COVID19 pandemic motivated a fast-tracked emergency authorization of vaccines. Majority studies of the efficacy of COVID19 vaccines have only utilized host-specific B cell (antibody) immune responses as the surrogate marker. This, because existing assays for cytotoxic T lymphocyte (CTL) responses are costly, complex and rigorous to standardize and perform. The commonest T cell assays (ELISPOT) focuses on quantifying T cell specific responses (mediated via cytokine and interferon mediators) to the target pathogen. Hypothetically, however, the elementary outcome and thereby functional surrogate biomarker of a desirable effective host T cell response, should be the clonal expansion of pathogen specific T cytotoxic cells. This study aims to describe the design of novel Cytotoxic T cell assays for point-of-care (POC) and laboratory measurements of host specific CTL responses to pathogens and vaccines.
Methods
Theoretical modelling and design
Results
Using severe acute respiratory syndrome type II (SARS-CoV2), two design-models of novel for the qualitative and quantitative measurement of host specific cytotoxic T cell responses to the same are presented: (a) a microfluidic lateral flow immunochromatography test (LFT) qualitative assay, and (ii) a quantitative enzyme immono-adsorbent assay (ELISA).
Conclusion
Qualitative and quantitative assay of host-specific T cytotoxic cells to a pathogen using these novel assays offers us affordable, simple and easy to use POC and laboratory alternatives for assessing the natural or vaccine induced T cytotoxic cell competency to fight off pathogens.

Abstract
Background
Patients on maintenance hemodialysis (MHD) frequently complain of insomnia. Poor sleep quality impairs their quality of life and adversely affects long-term outcome. Presently, the treatment for insomnia in MHD patients is mainly based on medication, though they have severe side effects and poor compliance in patients. It is a hot spot, therefore, to find complementary and alternative therapies with higher efficacy. This research aims to explore the clinical efficacy and safety of Tongdutiaoshen acupuncture on insomnia in MHD patients.
Methods
This randomized controlled trial (RCT) will be performed at the Beijing Luhe Hospital Affiliated to Capital Medical University in China. The Standards for Reporting Interventions in Clinical Trials of Acupuncture 2010 will be strictly adhered to. A total of 110 MHD patients with insomnia will be randomly allocated in a 1:1 ratio to drug control (DC) group or Tongdutiaoshen acupuncture (TA) group. Patients in the control group will be administered with eszolam tablets (1mg/d) for 4 weeks, followed by a 4-week follow up. On the basis of a background therapy as provided for the DC group, TA group will be given to the interventional cohort with 3 times a week for 4 weeks in a row, followed by a 4-week follow up. Primary endpoints will include Pittsburgh Sleep Quality Index (PSQI), Hamilton Anxiety Scale (HAM-A), TCM Insomnia Syndrome Score and clinical response rate, which will be evaluated on day 0, 14, 28 and 56 respectively. Secondary endpoints will include sleep data monitoring and its related laboratory indexes, which will be evaluated on day 0, 28 and 56 respectively.
Discussion
The study is designed based on a rigorous methodology to evaluate the efficacy and safety of Tongdutiaoshen acupuncture on insomnia in hemodialysis patients. The finding from this trial will be published in peer-reviewed journals as reliable evidence.

Self-synchronization of reinjected droplets for high-efficiency droplet pairing and merging
Authors: Shum Ho Cheung (Anderson) , Nan Lang , Mao Tianjiao 
Published: February 2023

Abstract
Droplet merging serves as a powerful tool to add reagents to moving droplets for biological and chemical reactions. However, unsynchronized droplet pairing impedes high-efficiency merging. Here, we develop a microfluidic design for self-synchronization of reinjected droplets. Periodical increase of hydrodynamic resistance caused by the droplet blocking in the T-junction enables automatic pairing of droplets. Through further spacing, the paired droplets are merged downstream under electric field. The blockage-based design can achieve a 100% synchronization efficiency even when the mismatch rate of droplet frequencies reaches 10%. Over 98% of the droplets can still be synchronized at non-uniform droplet sizes and fluctuated reinjection flow rates. Moreover, the droplet pairing ratio can be adjusted flexibly for on-demand sample addition. Using this system, we merge two groups of droplets encapsulating enzyme/substrate, demonstrating its capacity to conduct multi-step reactions. We also combine droplet sorting and merging to co-encapsulate single cells and single beads, providing basis for high-efficiency single-cell sequencing. We expect that this system can be integrated with other droplet manipulation systems for broad ranges of chemical and biological applications.
A link criticality approach for pedestrian network design to promote walking
Authors: Ukkusuri Satish , Verma Rajat 
Published: February 2023

Abstract
Measures of walkability generally do not provide a detailed quantitative assessment of pedestrian infrastructure development prioritization. In this study, a link-based composite measure of walkability and walking is introduced to overcome this limitation. This measure, called 'pednet score', is based on a weighted pedestrian network ('pednet') made of sidewalks and crosswalks whose edge weights are descriptive of their popularity. Edge popularity is derived from home-based walk trip assignment derived from simulated pedestrian demand. Properties of the pednet score are studied using three hypothetical variants of the pednet in three North American cities, each involving the addition of candidate sidewalk and/or crosswalk segments. It is shown that a strategic selection of these segments based on pednet score can substantially increase walking trips, in some cases up to 236%, and reduce current mean pedestrian trip distances by up to 340 m. A mixed development approach involving both sidewalks and crosswalks also shows considerably higher improvement than those segments considered alone. Results from marginal benefit curves strongly indicate the utility of the pednet score as a measure of link criticality for segment prioritization in pedestrian network design.
The Double-Protonation of Dihapto-Coordinated Benzene Complexes:
An Enabling Strategy for Dearomatization Using Aromatic Nucleophiles
Authors: Smith Jacob , Weatherford-Pratt Justin , Bloch Jeremy , Ericson Megan , Myers Jeffrey , Westendorff Karl , Dickie Diane , Harman Walter 
Published: February 2023

Abstract
Friedel Crafts Arylation (the Scholl reaction) is the coupling of two aromatic rings with the aid of a strong Lewis or Bronsted acid. This historically significant C-C bond forming reaction normally leads to aromatic products, often as oligomeric mixtures, dictated by the large stabilization gained upon their rearomatization. In this preliminary communication, we demonstrate how the pre-coordination of benzene by tungsten disrupts the natural course of this reaction sequence, allowing for Friedel-Crafts Arylation without rearomatization or oligomerization. Subsequent addition of a nucleophile to the coupled intermediate leads to functionalized cyclohexenes. The key feature of this reaction is a tungsten complex bound through two carbons, which enables a rarely observed double protonation of the bound benzene, and subsequent coupling to the second arene without the need of precious metal or Lewis acid catalysts.
