Nuevo Consenso Macroeconómico, estancamiento y agenda económicos: el caso brasileño
Authors: Ferrari Filho Fernando , Bittes Terra Fábio Henrique
Published: July 2024

Desde la implementación del marco teórico de la Macroeconomía del Nuevo Consenso (MNC) en Brasil, durante 1999 y 2000, la política fiscal se ha operacionalizado, principalmente, según una meta fiscal en términos de superávit presupuestario primario para apuntar a estabilizar la deuda en relación con el PIB. La tasa de interés parece tener un solo objetivo económico, es decir, llevar la tasa de inflación a sus intervalos de tolerancia, y el tipo de cambio se ha caracterizado por un régimen de flexibilidad cambiaria, administrado por el Banco Central de Brasil. A pesar de los objetivos esperados, las políticas económicas antes mencionadas, en el período 1999-2022, no lograron reducir la deuda pública –por el contrario, la relación entre deuda pública y PIB creció significativamente–, para mantener la inflación bajo control en niveles adecuados para países que adoptó un régimen de meta de inflación y el tipo de cambio fue volátil y apreciado durante la mayor parte del período. Además, en lo que respecta a la actividad económica, durante este período, el desempeño del PIB fue pobre, siendo el sector industrial el segmento productivo que perdió la mayor participación relativa en la composición del PIB brasileño. Teniendo esto en cuenta, el objetivo del artículo es mostrar en qué medida las políticas económicas de la MNC no sólo fueron responsables de una dinámica de estancamiento económico y crecimiento al estilo detente y sigue de la economía brasileña entre 1999 y 2022, sino que también contribuyeron al proceso de desindustrialización del país. Además, presenta una Agenda Económica para superar el estancamiento económico.
El verdadero ‘puente hacia el futuro’: desafíos y alternativas para la economía brasileña entre 2024 y 2026
Authors: Ferreira-Filho Helder Lara , Fraga Jefferson S.
Published: July 2024

Tras una breve contextualización de la economía brasileña durante las últimas dos décadas, este artículo subraya los problemas estructurales persistentes en la economía después de la crisis de 2014-2016. Sin embargo, la actual reducción de las restricciones de la balanza de pagos, atribuida en gran medida a los altos precios de las materias primas, en particular las exportaciones de petróleo, puede marcar una diferencia importante. Estas perspectivas favorables pueden permitir que el país experimente cambios estructurales sin comprometer su crecimiento. De cara a los desafíos de 2024 a 2026, o la construcción de un camino genuino hacia el "desarrollo sostenible", se vuelve imperativo aumentar la inversión pública en infraestructuras e innovación. Además, las mejoras en los niveles educativos son esenciales, ya que están vinculadas con el aumento de la productividad de la economía, junto con la búsqueda de un régimen fiscal equilibrado y sostenible.
FBXO24 deletion causes abnormal accumulation of membraneless electron-dense granules in sperm flagella and male infertility

Published: July 2024

Ribonucleoprotein (RNP) granules are membraneless electron-dense structures rich in RNAs and proteins, and involved in various cellular processes. Two RNP granules in male germ cells, intermitochondrial cement and the chromatoid body (CB), are associated with PIWI-interacting RNAs (piRNAs) and are required for transposon silencing and spermatogenesis. Other RNP granules in male germ cells, the reticulated body and CB remnants, are also essential for spermiogenesis. In this study, we disrupted FBXO24, a testis-enriched F-box protein, in mice and found numerous membraneless electron-dense granules accumulated in sperm flagella.
Fbxo24
knockout (KO) mice exhibited malformed flagellar structures, impaired sperm motility, and male infertility, likely due to the accumulation of abnormal granules. The amount and localization of known RNP granule-related proteins were not disrupted in
Fbxo24
KO mice, suggesting that the accumulated granules were distinct from known RNP granules. Further studies revealed that RNAs and two importins, IPO5 and KPNB1, abnormally accumulated in
Fbxo24
KO spermatozoa and that FBXO24 could ubiquitinate IPO5. In addition, IPO5 and KPNB1 were recruited to stress granules, RNP complexes, when cells were treated with oxidative stress or a proteasome inhibitor. These results suggest that FBXO24 is involved in the degradation of IPO5, disruption of which may lead to the accumulation of abnormal RNP granules in sperm flagella.

Published: July 2024

Sepsis causes millions of deaths per year worldwide and is a current global health priority declared by the WHO. Sepsis-related deaths are a result of dysregulated inflammatory immune responses indicating the need to develop strategies to target inflammation. An important mediator of inflammation is extracellular adenosine triphosphate (ATP) that is secreted by inflamed host cells and tissues, and also by bacteria in a strain-specific and growth phase-dependent manner. Here, we investigated the mechanisms by which bacteria release ATP. Using genetic mutant strains of
Escherichia coli
(
E. coli
), we demonstrate that ATP release is dependent on ATP synthase within the inner bacterial membrane. In addition, impaired integrity of the outer bacterial membrane and bacterial death notably contribute to ATP release. In a mouse model of abdominal sepsis, local effects of bacterial ATP were analysed using a transformed
E. coli
bearing an arabinose-inducible periplasmic apyrase hydrolyzing ATP to be released. Abrogating bacterial ATP release shows that bacterial ATP suppresses local immune responses, resulting in reduced neutrophil counts and impaired survival. In addition, bacterial ATP has systemic effects via its transport in outer membrane vesicles (OMV). ATP-loaded OMV are quickly distributed throughout the body and upregulated expression of genes activating degranulation in neutrophils, potentially contributing to the exacerbation of sepsis severity. This study reveals mechanisms of bacterial ATP release and its local and systemic roles in sepsis pathogenesis.
Nonlinear sensitivity to acoustic context is a stable feature of neuronal responses to complex sounds in auditory cortex of awake mice

Published: July 2024

The perceptual salience of a sound depends on the acoustic context in which it appears, and can vary on a timescale of milliseconds. At the level of single neurons in the auditory cortex, spectrotemporal tuning for particular sounds is shaped by a similarly fast and systematic nonlinear sensitivity to acoustic context. Does this neuronal context sensitivity “drift” over time in awake animals, or is it a stable feature of sound representation in the auditory cortex? We used chronically implanted tetrode arrays in awake mice to measure the electrophysiological responses of auditory cortical neurons to spectrotemporally complex, rapidly varying sounds across many days. For each neuron in each recording session, we applied the nonlinear-linear “context model” to estimate both a principal (spectrotemporal) receptive ﬁeld and a “contextual gain ﬁeld” describing the neuron’s nonlinear sensitivity to acoustic context. We then quantiﬁed the stability of these ﬁelds within and across days, using spike waveforms to match neurons recorded in multiple sessions. Contextual gain ﬁelds of auditory cortical neurons in awake mice were remarkably stable across many days of recording, and comparable in stability to principal receptive ﬁelds. Interestingly, there were small but signiﬁcant effects of changes in locomotion or pupil size on the ability of the context model to ﬁt temporal fluctuations in the neuronal response.We conclude that both spectrotemporal tuning and nonlinear sensitivity to acoustic context are stable features of neuronal sound representation in the awake auditory cortex, which can be modulated by behavioral state.
Guardian of Excitability: Multifaceted Role of Galanin in Whole Brain Excitability
Authors: Rieser Nicolas N , Ronchetti Milena , Hotz Adriana L , Neuhauss Stephan CF
Published: July 2024

Galanin is a neuropeptide, which is critically involved in homeostatic processes like controlling arousal, sleep, and regulation of stress. This extensive range of functions aligns with implications of galanin in diverse pathologies, including anxiety disorders, depression, and epilepsy. Here we investigated the regulatory function of galanin on whole-brain activity in larval zebrafish using wide-field Ca
2+
imaging. Combining this with genetic perturbations of galanin signaling and pharmacologically increasing neuronal activity, we are able to probe actions of galanin across the entire brain. Our findings demonstrate that under unperturbed conditions and during epileptic seizures, galanin exerts a sedative influence on the brain, primarily through the galanin receptor 1a (
galr1a
). However, exposure to acute stressors like pentylenetetrazole (PTZ) compromises galanin’s sedative effects, leading to overactivation of the brain and increased seizure occurrence. Interestingly, galanin’s impact on seizures appears to be bidirectional, as it can both decrease seizure severity and increase seizure occurrence, potentially through different galanin receptor subtypes. This nuanced interplay between galanin and various physiological processes underscores its significance in modulating stress-related pathways and suggests its potential implications for neurological disorders such as epilepsy. Taken together, our data sheds light on a multifaceted role of galanin, where galanin regulates whole-brain activity but also shapes acute responses to stress.
Microbiota from young mice counteracts susceptibility to age-related gout through modulating butyric acid levels in aged mice

Published: July 2024

Gout is a prevalent form of inflammatory arthritis that occurs due to high levels of uric acid in the blood leading to the formation of urate crystals in and around the joints, particularly affecting the elderly. Recent research has provided evidence of distinct differences in the gut microbiota of patients with gout and hyperuricemia compared to healthy individuals. However, the link between gut microbiota and age-related gout remained underexplored. Our study found that gut microbiota plays a crucial role in determining susceptibility to age-related gout. Specifically, we observed that age-related gut microbiota regulated the activation of the NLRP3 inflammasome pathway and modulated uric acid metabolism. More scrutiny highlighted the positive impact of ‘younger’ microbiota on the gut microbiota structure of old or aged mice, enhancing butanoate metabolism and butyric acid content. Experimentation with butyrate supplementation indicated that butyric acid exerts a dual effect, inhibiting inflammation in acute gout and reducing serum uric acid levels. These insights emphasize the potential of gut microbiome rejuvenation in mitigating senile gout, unraveling the intricate dynamics between microbiota, aging, and gout. It potentially serves as a therapeutic target for senile gout-related conditions.
The skull of the Turks and Caicos rock iguana, Cyclura carinata (Squamata: Iguanidae)
Authors: Lai Chloe , Scarpetta Simon G.
Published: July 2024

We provide a detailed and first description of the skull, hyoid apparatus, and trachea of the Turks and Caicos rock iguana, Cyclura carinata (Squamata: Iguanidae). Cyclura is a radiation of iguanas restricted to islands of the Caribbean Sea. Species of Cyclura have high rates of endemism, and all species are severely threatened with extinction. Our anatomical description of this threatened iguana is based on high-resolution computed tomography scans of one adult, one putative adult or near adult, and one juvenile specimen, and includes three-dimensional segmented renderings and visualizations. We discuss some observations of intraspecific and ontogenetic variation, and provide a brief comparison with specimens of another species of Cyclura and published descriptions of other iguanas. Our study provides a cranial osteological framework for Cyclura and augments the body of knowledge on iguana anatomy generally. Finally, we posit that our description and future studies may facilitate identification of fossil Cyclura, which could help understand the paleobiogeography of the genus.

Authors: ÇETİN Kadir , KÜÇÜKKÖMÜRLER Saime
Published: July 2024

The study's aim is to reveal domestic tourists' gastronomic experiences and to test the impact of local cuisine's appeal on the experience under consideration. Data was collected from 727 domestic visitors who visited Gaziantep, Hatay,
and Afyonkarahisar, all of which are designated as Cities of Gastronomy. As a result, indicate that involvement, knowledge, and authenticity perception positively influence the appeal of local cuisine, which in turn positively
affects the gastronomy experience. The perception of authenticity also has a direct negative impact on the gastronomy experience. The study suggests practical implications for food and beverage enterprises, travel agencies, and
local administrations in gastronomy destinations. These include organizing promotional activities that highlight the appeal of local cuisine, presenting local cuisine in an attractive manner, ensuring compatibility between destination
services and tourists' expectations, and incorporating distinctive experiences related to local cuisines. The study acknowledges limitations and suggests future research directions, such as longitudinal studies, inclusion of international
tourists, examination of cultural differences, and investigation of specific variables related to facility quality and service interactions. Overall, the study contributes to the literature by identifying the factors influencing
the appeal of local cuisine and their impact on gastronomy experiences, providing insights for stakeholders in gastronomy destinations.
An Evaluation on the Applicability of the Hydraulic Hypothesis to Urartian Irrigation Systems
Authors: ÖZBİLEN Serdar
Published: July 2024

Suyun toplumların gelişiminde hayati bir öneme sahip olduğu bilinen bir gerçektir. Su yönetimi araştırmalarındaki baskın paradigma "hidrolojik döngü" konusu olmuştur. Büyük nehir vadilerinde ortaya çıkan medeniyetlerin gelişim tarihlerinde
sulamaya olan bağımlılıkları nedeniyle, sulamanın organizasyonu konusunda benzer bir yörünge izledikleri görülmektedir. Antik sulamanın örgütlenmesi, sosyal ve politik karmaşıklığın gelişmesine ve nihayetinde devletin oluşumuna
yol açan bir büyüklükte sosyo-politik ve ekonomik sonuçları olan merkezi kontrolün gerekliliğini beraberinde getirmiştir. Bununla birlikte suyun antik toplumlarda merkezi otorite ile olan ilişkisi pek çok çalışmaya konu olmuştur.
Bu çalışmalardan birisi de 1957 yılında Karl August Wittfogel tarafından ortaya atılan “Hidrolik Hipotez”dir. Wittfogel, merkezi ve despotik yönetimin eski "hidrolik toplumlarda" devlet oluşumunun ayırt edici özelliği olduğunu
savunmuştur. Bu yüzden antik su yönetiminin arkeolojisi ve antropolojisi, büyük ölçüde Wittfogel'in çalışmasından yararlanır. Bu bağlamda, kanal sistemleri oluşturmak ve sürdürmek için sosyal organizasyon derecesine duyulan ihtiyaç,
"hidrolik hipotez"i doğurmuştur. Bu çalışması ile birlikte Wittfogell kendisinden sonra pek çok çalışmanın oluşumuna ivme kazandırmıştır. Ancak pek çok eleştiriye de neden olmuştur. Bu çalışmamızda Wittfogel’in Hidrolik Hipotezi
ışığında merkezi kontrolün etkisine ve Urartu sulama sistemleri üzerindeki yerine değineceğiz. Hidrolik Hipotez ve Urartu ile ilişkilendirilen çalışmaların yok denecek kadar az oluşu göz önüne alındığında, söz konusu çalışmamızın
birçok çalışmaya ön ayak olacağını düşünmekteyiz. Yöntem olarak ise Hidrolik Hipotezde değinilen Japonya örneğini Urartu ile bağdaştırarak bir takım sonuçlara ulaşmaya çalıştık.

Published: July 2024

В статье приводятся результаты изучения систематического и количественного состава раковин моллюсков в трех пробах, отобранных в береговых выбросах Азовского моря. Общая особенность всех проб - бедность систематического состава комплексов моллюсков, особенно брюхоногих. Однако бедность видового разнообразия компенсируется высоким количественным содержанием доминантных двустворок. Предполагается, что состав комплексов моллюсков в береговых выбросах зависит от изрезанности береговой линии бассейна. Ассоциации моллюсков в береговых выбросах, сформированных на закрытых участках побережья, более точно отражают разнообразие и численный состав моллюсков в биоценозах.

Предложена и исследована конструкция микрополоскового фотонного кристалла на однородной диэлектрической подложке, которая отличается тем, что ширина токоведущего проводника микрополосковой линии остается неизменной по всей длине, в то время как сегнетоэлектрическая пленка, на которую нанесен полосковый проводник, периодически вытравлена. Для теоретического анализа исследованного фотонного кристалла использована коммерческая программа Microwave Office с добавлением разработанных дополнительных программ, позволяющих проводить электродинамический анализ многослойных диэлектрических структур. Проведен электродинамический расчет характеристик исследованного фотонного кристалла - частотных зависимостей коэффициентов передачи и отражения его матрицы рассеяния. Для решения задачи был использован электродинамический метод, известный как метод моментов. Расчет проводился при соблюдении так называемого четвертьволнового условия, которое является необходимым для получения оптимальных характеристик фотонного кристалла. Проведен анализ частотных характеристик коэффициентов матрицы рассеяния исследованного фотонного кристалла, показано наличие эквидистантно расположенных фотонных запрещенных зон в его частотном спектре. Проведено моделирование влияния параметров исследованного фотонного кристалла на появление в его частотном спектре фотонных запрещенных зон. Установлено, что основными параметрами, которые оказывают доминирующее влияние на появление фотонных запрещенных зон в частотном спектре анализируемой структуры с периодически вытравленной наноразмерной пленкой, являются толщина сегнетоэлектрической пленки, величина диэлектрической постоянной пленки, а также толщина металлизации проводников микрополосковой линии. Показаны преимущества предложенной конструкции фотонного кристалла над известными микрополосковыми аналогами. Предложенная конструкция для своей реализации требует несравненно меньших технологических усилий и затрат, нежели фотонные кристаллы на композитной подложке с аналогичными характеристиками. Указаны возможные области применения исследованной структуры с периодически вытравленной наноразмерной сегнетоэлектрической пленкой.

Синтезирована серия кумарин-терпиридиновых иминных конъюгатов. Полученные соединения обладают флуоресценцией в районе 504-568 нм с большой величиной сдвига Стокса (9050-12500 см-1), обусловленной быстрым внутримолекулярным О->N переносом протона в возбужденном состоянии с образованием короткоживущего кетоаминного изомера. Они представляют собой полифункциональные ионохромные naked-eye-системы, способные к детектированию катионов Fe2+ за счет комплексообразования с терпиридиновым фрагментом (изменение окраски раствора со светло-желтой на малиновую) и Zn2+ (комплексообразование по о-гидроксииминовому фрагменту). При этом наблюдается уменьшение интенсивности исходной эмиссии конъюгатов до нулевых значений или появление интенсивной флуоресценции комплекса с цинком(II). Кроме того, кумарин-терпиридиновые конъюгаты селективно реагируют на фторид и цианид-анионы с изменением окраски раствора со светло-желтой на оранжевую. Таким образом, полученные соединения представляют собой удобную платформу для разработки хромогенных и флуорогенных сенсоров для определения катионов и анионов.

Определение половозрелой особи проводилось по конхологическим признакам, указанным в справочных изданиях и специальной литературе, ювенильной - методом секвенирования фрагмента гена цитохромоксидазы I. По результатам сравнения нуклеотидной последовательности изученного образца с последовательностями, депонированными в онлайн базах данных, особи улиток, обнаруженные на федеральной территории «Сириус», имеют вероятное происхождение из Южной Европы. Литературные источники с данными о находках вида С. aspersum на территории современной Российской Федерации свидетельствуют о неоднократном проникновении средиземноморского наземного моллюска на территорию Восточной Европы. Наиболее вероятным способом проникновения этой улитки на федеральную территорию «Сириус» является транспортировка в почве вместе с посадочным материалом из Италии при строительстве Олимпийского парка и озеленении в 2013 г. Натурализация чужеродного вида С. aspersum может представлять опасность не только для парковых и лесомелиоративных насаждений, но и для экосистем особо охраняемой природной территории регионального значения Природного орнитологического парка в Имеретинской низменности.

Published: July 2024

The use of plants to remove, detoxify, or immobilize environmental contaminants, a process known as phytoremediation, is an emerging field with significant potential for the sustainable and economical treatment of polluted water bodies. Aquatic plants are uniquely suited for this purpose due to their inherent capabilities to uptake and metabolize a diverse range of pollutants such as heavy metals, pesticides, and organic compounds. Although the method does present challenges, including the length of time for effective cleanup and potential toxin bioaccumulation, innovative advancements in fields like genetic engineering and integrated remediation techniques offer promising avenues to overcome these hurdles. Additionally, the function of phytoremediation in carbon sequestration, paired with potential commercial uses, underscores its role as an essential tool for sustainable environmental stewardship. Therefore, it's crucial to continue research, encourage policy backing, and foster community participation to fully exploit the benefits of phytoremediation in aquatic settings.

Authors: Chinenye Nna Orji,
Published: July 2024

Spent oil, which contains hazardous substances that pose health risk to man and his environment, are disposed indiscriminately on land in most mechanic workshops. The waste oil find its way into farmland and water bodies causing contamination of water, plants and lands. The ingestion of contaminated water, plants and animals lead to serious health issues. The abilities of plant wastes such as Citrullus colocynthis peels were investigated for the enhancement of the biodegradation of spent oil in soils. Contaminated soil in microcosms, A to J, were treated with plant wastes, duplicated to give 20 microcosms and incubated for 180 days. Periodic soil sampling from each microcosm was followed by cold extraction with dichloromethane and residual oil were analysed via Gas Chromatography/ Mass Spectrometry techniques (GC/MS). The results showed that the biostimulants accounted for 55.2 % of the total variation in the biodegradation result, P<0.001 at α = 0.05. The compounds identified ranged from C10- C35. The highest molecular weight compounds were 17-Pentatriacontene, 490.93 g/mol and 1-Hexacosene, 490.93 g/mol, while the lowest was p-Menth-8(10)-en-9-ol, cis, 154.25 g/mol. The compounds with the highest and lowest area percentage, 36.04 % and 0.97 % were 9-Octadecenamide, (Z)-, and 9, 9-Dimethyl-9-sila-9,10-dihydrophenanthrene respectively. About, four alkanes, six alkene, fourteen oxygenated, five nitrogen containing- and eight aromatic- compounds were identified after biodegradation. There was no statistical significant difference between the performances of each of the stimulant in the microcosms, P>0.1 at α = 0.05. There was an extremely significant difference between the performance of the stimulated microcosms and the natural attenuation containing NaN3, with P<0.001 at 0.05 significant level. The results show that plant wastes have abilities to enhance the biodegradation of the spent oil. Hence, Citrullus colocynthis peels generated in the Northern Nigeria and other plant waste can be used for cost-effective and safe degradation of spent and crude oil in the Southern Nigeria for the reclamations of lands for agricultural purposes.

Published: July 2024

Hypospadias is a birth defect that involves the development of a penile urethra that opens on the ventral side of the penis. Proximal hypospadias is one of the most severe forms of hypospadias that is generally associated with chordee. Hypospadias surgery, especially in the proximal location, is challenging, and many operations have been proposed, including one-stage and two-stage operations.
Objectives: The aim of the study was to evaluate the success rate and safety of a single-stage surgery in children with proximal hypospadias and to determine the complications.
Materials and Methods: This interventional study was conducted on forty patients, aged between one and twelve years, who had proximal hypospadias and were admitted to Mymensingh Medical College Hospital between January 2014 and April 2015. A one-step operation with tabularized incised plate urethroplasty (TIPU) was done. Patients’ demographic data, intraoperative details, and postoperative outcomes were recorded within 3 months after the operation.
Results: The common age at surgery was 2-4 years, and they were 40% of the total patients. There was Haematoma in 5% of cases, a devitalized skin flap in 7.5% of cases, and stent blockage in 10% of cases during the immediate postoperative period. In our 3-month follow-up, all the patients had conical glans and cylindrical penises. Meatal stenosis and narrow stream were noted in 5 percent of patients but were relieved with meatal dilatation. Urethrocutaneous fistulas remained patients in 7.5% of cases.
Conclusion: TIPU repair of proximal hypospadias is safe, effective, yields good results, and has low risks of complications in otherwise healthy children. It is a less risky and more viable method that helps to exclude extra steps in the process.

Published: July 2024

Aims: The construction of Geothermal Power Plants in several regions in Indonesia is currently always characterized by conflict and opposition from local communities, including in Serang Regency. One of the main issues is the company’s inappropriate communication strategy, resulting in a lack of community acceptance and leading to conflicts. The research focuses on the different stages of conflict, behavior and communication of conflicting parties within managing conflict strategies. Researchers utilize Galtung's conflict model and the convergence-divergence communication theory.
Methodology: The research method used is qualitative research through the examination of case studies. This was done because the problems in this research remained unclear, holistic, complex, dynamic and full of meaning. Meanwhile, the data collection techniques used in this research were documentation obtained 73 news published by 35 online media covering statistics on yearly citizen actions and newspaper publications, news topics or discussions, and online news coverage on the construction of the Geothermal Power Plant in Serang regency, Indonesia. Also, with direct field observations and in-depth interviews with several informants at the study location.
Results: Based on research findings, the Geothermal Power Plant conflict went through 4 stages, including the initial conflict phase; conflict phase; the trust-building phase leading to conflict resolution; and the conflict resolution phase. Meanwhile, based on Galtung's theory, conflict occurs when there is a discrepancy between the socialization provided by the company and the community’s direct experiences, leading to rejection through various actions. The divergent communication approach utilized by the company towards the affected communities resulted in different interpretations, ultimately causing the root of the conflict.
Conclusion: The conflict stages in the Geothermal Power Plant development project in Serang regency are divided into several phases that closely related with communication occurred between company, government and the local communities. Lack of communication formed negative opinions about the project developers, leading them to oppose the construction of the Geothermal project. The convergent communication model combined with other communication models such as open, participatory and supportive communication is considered to be highly effective in addressing conflicts.

Published: July 2024

Fimbristylis miliacea (L.) Vahl, commonly referred to as globe fringerush, member of the Cyperaceae family, is a significant and widespread sedge weed in rice cultivation. This C4 plant is characterized by its tall, annual or perennial growth, featuring a fibrous root system and smooth stems, often producing vigorous tillers reaching heights of 80-90 cm. Seedlings of F. miliacea typically emerge shortly after rice is planted, with flowering occurring within about a month, capable of producing a second generation within the same growing season. Found extensively throughout tropical regions, especially in lowlands, F. miliacea thrives in environments such as rice fields, shallow water along ditches, and streams, notably prevalent across South and Southeast Asia, as well as Australia. This weed presents enduring challenges across diverse agro-ecosystems due to its various ecotypes, prolific seed production, rapid germination, vigorous growth, strong competitive abilities and allelopathic interactions. Temperature is a critical factor significantly influencing seed germination of F. miliacea which exhibits non-deep physiological dormancy. Light is essential for the germination of this weed showing positive photoblastic behaviour. F. miliacea thrives in saturated soils but fails to emerge from depths greater than one cm, emphasizing the importance of shallow tillage to manage weed emergence effectively. Effective weed management hinges on a deep understanding of the factors that favour its emergence and establishment. Adopting the germination ecology-based practices such as tillage, stale seed bed preparation, optimal planting density, water management and nutrient management can significantly improve the management of F. miliacea.

Published: July 2024

The grain crop known as sorghum [Sorghum bicolor (L.) Moench], which belongs in the Poaceae family, is said to have evolved from Ethiopia or Sudan. This is a crucial crop for food security, especially within the tropical and semi-arid regions in African nations. By terms of long-term domestication and genetic diversity, this crop was native from Ethiopia.
showed differences between the crop's cultivated and wild ancestors that gathered within the nation. Due to its enormous diversity of sorghum, which shows innate biological resistant to disease, dryness, and insects in addition to having large lysine content and excellent quality of grain, Ethiopia has become the world's top contributor of germplasm for the sorghum breeding programmes. Ethiopian landraces referred to as "zera zera" sorghum and the generations that sprang of those were used in ICRISAT along with other nations' contemporary sorghum breeding programmes for hybrids creation. Sorghum is at present Ethiopia's second most significant cereal crop after the tef with regard to of its combined area covered and productivity, which means it's used to make injera. Sorghum genotype from Ethiopia is varied and has responded to a variety of rainfall conditions and elevations. Plant breeding starts with the characterisation and recognition of sorghum seeds that offer desired features for improved genetics. When contrast with field trial evaluation, DNA-based molecular markers and PCR-based methods were most effective in characterising and identifying sorghum genotypes which offer desired features since they are unaffected by duration or climate. The most economical method of increasing sorghum production for many applications is genetic enhancement. Gaining more knowledge about sorghum's genetic diversity could be extremely beneficial for improving the crop in terms of quality of food along with other crucial agronomic characteristics. Sorghums from the Ethiopian Centre of Crop Diversity have a vast amount of genetic variety. To effectively gather and conserve this genetic variety before it is overrun and lost, some serious work is required.
