Case series of spontaneous bilateral absorbed cataracts running in a family
Authors: Chaudhary Aparajita , Bhatt Kriti
Published: January 2024

There are only a handful of case reports and studies available regarding spontaneously absorbed cataracts and their management, including the surgical techniques and results following the management. In our study, on retrospective analysis, after a thorough search of the concerned literature, we encountered a series of cases of bilateral spontaneous absorbed cataracts running in a family with no such documentation. This retrospective study included 11 patients (aged between 3 and 65 years and of either sex) of the same family having bilateral absorbed cataracts. All patients underwent best-corrected visual acuity (BCVA); a thorough eye examination; rubella titer estimation; intraocular lens (IOL) power calculation; lens aspiration with or without posterior capsulotomy, anterior vitrectomy (AV), or IOL implantation; and visual rehabilitation. All patients had bilateral absorbed cataracts, which were acquired in an autosomal dominant pattern. Preoperative BCVA distance: 22 eyes had either counting fingers close to the face or counting fingers at 1–2 feet. The presence of high-frequency mixed bilateral nystagmus was noted in four patients. Anterior continuous curvilinear capsulorhexis was possible. Cortical aspiration was uneventful. In the capsular bag, implantation was possible in the majority of cases. No postoperative inflammation was noted, and the IOL was well-centered in all patients. To the best of our knowledge, this is the first study to report a case series of bilateral absorbed cataracts running in an Indian family with no syndromic association, no history of mental retardation, or infection. Anatomic disorganization of the absorbed lens makes surgery in such cases challenging. By using appropriate surgical methods and good visual rehabilitation, satisfactory surgical and visual outcomes can be achieved.

Authors: Sundari N Parvatha , Rajeswari E , Preethi V
Published: January 2024

Doyne’s honeycomb dystrophy is a rare hereditary retinal dystrophy where drusens form in the macula and around the optic nerve head, resulting in choroidal neovascularization later. We report the case of a 63-year-old male with metamorphopsia in the right eye (RE) since 6 months. On examination, his visual acuity was 6/6 in both eyes. The anterior segment was normal. Fundus examination showed multiple drusen deposits in the macula and optic nerve head and hyperpigmentation in the macula. OCT showed hyperreflective bumpy retinal pigment epithelial in Bruch’s membrane. Fundus autofluorescence of both showed hyperfluorescence in areas of drusens. Fundus fluorescein angiography of the RE showed hyperfluorescence with central hypofluorescence. The left eye showed areas of blocked hypofluorescence within areas of hyperfluorescence.

Authors: Subramaniam Prema , Shah Parag K , Maitra Puja , Das Abhishek
Published: January 2024

Herein, we present a case series encompassing three families characterized by a diverse phenotype and a distinctive genotype. In the first family, the patient exhibited bilateral retinoblastoma, while the elder sibling manifested retinocytoma; both parents displayed no abnormalities. In contrast, the second family featured a mother with bilateral retinoblastoma and the older sister showed retinocytoma. The third family presented cases of retinoblastoma in both the patient and the younger sibling, with the father exhibiting retinocytoma. Genetic analysis uncovered mutations in the blood of the proband, elder sibling, and mother in the first and second families, while the third family exhibited mutations in the father and both offspring. Notably, this series underscores the presence of variable expressivity and penetrance, particularly evident in the first family’s experience with retinoblastoma.

Published: January 2024

Leptospira is an emerging cause of acute febrile illness in India, which is acquired through contact of skin with contaminated water and soil. Generally, leptospirosis has mild, self-limiting course; rarely, multiple organ dysfunction can occur like aseptic meningitis (20%) and Weil’s disease (10%). Here, we report a case of bilateral optic neuritis in a girl child who presented with blindness following Leptospira infection. On ophthalmological examination, she could appreciate hand movements close to face and had afferent pupillary defect bilaterally. Fundoscopy showed normal fundus with no signs of disc edema. Magnetic resonance imaging (MRI) of brain and orbit showed bilateral hyperintensities in the optic nerve. Visual evoked potential showed prolonged latency in p100 wave in both eyes, suggestive of bilateral optic neuritis. She was diagnosed with Leptospira infection with aseptic meningitis and retrobulbar optic neuritis. She was treated conservatively. She responded well with improvement of visual acuity to 6/6 at the time of discharge.

Authors: Zhu Xinlei , Xing Xiaoli , Li Dongfang , Yu Bin
Published: January 2024

A 23-year-old male patient visited our Eye Institute for “retinal detachment with dialysis of the ora serrata in left eye”. Through high-throughput exon sequencing, he was correctly diagnosed with Kniest dysplasia caused by the COL2A1 gene mutation. The retina was successfully reattached, and the vision recovered to 20/25 after pars plana vitrectomy and silicone oil injection. Retinal detachment in Kniest dysplasia is the most serious ocular complication. In order to prevent blindness, early diagnosis and regular eye examination are necessary. If a retinal detachment is found, pars plana vitrectomy to reattach the retina as soon as possible is an effective treatment.

Published: January 2024

We report two cases of posterior scleritis (PS) where ocular thermography was used to monitor ocular surface temperature (OST). Case 1 was a known case of recurrent non-granulomatous anterior uveitis presented with pain in the left eye (OS). A relapse of anterior uveitis was suspected, but slit-lamp biomicroscopy was normal. Thermography showed increased temperature in OS, and B-scan confirmed PS in OS. Case 2, a known case of PS, during follow-up visits, was found to have increased OST in OS on two occasions, but no inflammation was detected clinically. Within the next 2 weeks, the patient returned with relapse on both occasions.

Authors: Mooss Vidya S , Konana Vinaya K , Murthy Kalpana B
Published: January 2024

We report a rare association of retinal vascular occlusion in post-fever retinitis (PFR). A 58-year-old male presented with a vision of 3/60 in the right eye and 6/24 in the left eye 1 month after an episode of fever. Examination revealed vitritis (4+), cotton wool spots, venous beading and hemorrhages in both eyes, and retinal whitening superior and temporal to the fovea in the right eye suggestive of arteriolar occlusion. Optical coherence tomography (OCT) showed inner retinal hyperreflectivity, and OCT angiography showed flow-void areas corresponding to the area of whitening confirming occlusion. Our findings, together with those from previous studies, show that retinal vascular occlusive events, predominantly involving the arterial circulation, may complicate PFR.

Published: January 2024

A 57-year-old male, diagnosed with mycosis fungoides and managed with immunomodulators, presented with a history of acute exacerbation of pain and redness in the right eye for 1 week. On examination, the patient exhibited a bright erythematous lesion involving the ala and apex of the nose. A provisional diagnosis of acute scleritis secondary to mycosis fungoides was made, and the patient was initiated on oral and topical steroids. Within 2 weeks, the patient gradually improved; however, with decreased congestion and increased visibility of the ocular surface, a pigmented foreign body was visualized in the subconjunctival space, which was subsequently removed with a 26-gauge needle. Surprisingly, histopathologic examination revealed the foreign body to be a bee sting.
Lo and behold! An inverted hypopyon in the cornea! – Intrastromal sequestered corneal infection

Published: January 2024

To report two unique cases of intrastromal liquified corneal abscess following penetrating trauma to the cornea. We report two cases of a 12-year-old and an 11-year-old child who developed liquified purulent intrastromal fluid collections corneal abscess following penetrating trauma to the cornea. We present the investigative workup and the subsequent management with a review of the literature and describe a new “inverted hypopyon in the corneal stroma” sign to characterize the diagnosis. No similar cases have been reported so far. A provisional diagnosis of intrastromal corneal abscess was made in both cases, and surgical intervention was undertaken. Patient 1 was planned for abscess drainage, and Patient 2 was planned for penetrating keratoplasty along with abscess drainage. The drained pus was sent for bacterial and fungal culture and antimicrobial sensitivity. Both patients were treated with topical moxifloxacin 0.5% for 4 weeks and regained good vision with no recurrence of infection in the postoperative period. We conclude that intrastromal corneal abscesses are usually common following penetrating trauma but mostly involve all the layers of the cornea, often leading to corneal perforation. Such cases are mostly fungal in nature. However, our patients presented with a well-defined intrastromal bacterial abscess with liquified pus creating an “inverted hypoyon in the corneal stroma” sign and were effectively managed surgically. Such cases and the clinical sign have not been reported before.
The hydrops masquerade

Published: January 2024

Herein, we report an unusual case of corneal perforation presenting with acute hydrops. A 70- year-old male presented with complaints of sudden painful diminution of vision in the left eye, along with watering and foreign body sensation, following a history of trauma with fingernail. Anterior segment evaluation showed mild conjunctival congestion and diffuse corneal edema with few bullae. There was inferior corneal thinning and protrusion resembling the appearance of a pellucid marginal degeneration with acute hydrops. However, intraoperatively, it was found to be a partial-thickness corneal laceration with edematous lacerated anterior corneal flap, which was repaired with 10-0 monofilament interrupted sutures. Longstanding lamellar corneal laceration with resultant edema of the superficial lacerated corneal flap might mimic an acute corneal hydrops presentation.

Embedded System Technology Spillover Effects of Digital Economy and High-Quality Economic Development
Authors: Gao Jian
Published: January 2024

INTRODUCTION: With the development of digital technology and computer technology, the theory of digital economy has also had far-reaching development, but at present, the digital economy is still not able to clearly define whether the digital economy is good or bad for the high-quality development of China's economy. Therefore, it is necessary to research the spillover effect of the digital economy and the high-quality development of the economy with the help of embedded system technology.OBJECTIVES: To solve the issue of the poor coupling between the digital economy and high-quality development, to raise the degree of China's digital economic development, to improve the high energy consumption in the course of China's economic high-quality development, and to improve the application level of system technology in the study of China's economic development.METHODS: The digital economy model is established using the entropy weight method; its efficiency is evaluated using embedded system technology; the spillover effect analysis of high-quality development is then conducted using the digital economy index; and lastly, the overall assessment of the spillover effect is conducted using the comprehensive evaluation results of the entropy weight method.RESULTS: Embedded system technology has a noticeable promotion effect on the development of the digital economy; although the development of the digital economy and economic high-quality development are poorly coupled, their promotion effect is more significant; embedded system technology can indirectly promote the development of economic high-quality development through the digital economy.CONCLUSION: China should vigorously develop embedded system technology to promote the application of new technology in the economy and should further standardize the market economic order to maintain the orderly development of the digital economy.

Authors: Ospino Javier Orozco , Yepes Gloria Yaneth Florez
Published: January 2024

Effectively managed protected areas (PAs) are an efficient strategy to promote sustainable development and human well-being. The objective of this study was to examine aspects related to the evaluation of PA effectiveness and management, for which a bibliometric analysis was performed by taking as a reference the English language publication made globally from 2013 to 2022 in the Scopus database. Three research trends were found. The first is studies on conservation planning, management, and evaluation, with multiple approaches aimed at developing tools to determine PA effectiveness objectively. The second studies the impacts of human activities on PAs and considers human pressure, the impacts of anthropogenic climate change, and the valuation of ecosystem services, among others. The third studies specific indicators to determine the effectiveness of a specific set of PAs or one in particular. Finally, conservation management was identified as a basic topic that has not been sufficiently developed, so the convenience of developing management and evaluation models for PA management should be evaluated in future research.

For each

p\geq 1

, the star automaton group

\mathcal{G}_{S_p}

is an automaton group which can be defined starting from a star graph on

p+1

vertices. We study Schreier graphs associated with the action of the group

\mathcal{G}_{S_p}

on the regular rooted tree

T_{p+1}

of degree

p+1

and on its boundary 

\partial T_{p+1}

. With the transitive action on the

n

-th level of

T_{p+1}

is associated a finite Schreier graph 

\Gamma^{p}_{n}

, whereas there exist uncountably many orbits of the action on the boundary, represented by infinite Schreier graphs which are obtained as the limits of the sequence

\{\Gamma_{n}^{p}\}_{n\geq 1}

in the Gromov–Hausdorff topology. We obtain an explicit description of the spectrum of the graphs

\{\Gamma_{n}^{p}\}_{n\geq 1}

. Then, by using amenability of

\mathcal{G}_{S_p}

, we prove that the spectrum of each infinite Schreier graph is the union of a Cantor set of zero Lebesgue measure, which is the Julia set of the quadratic map

f_{p}(z) = z^{2}-2(p-1)z -2p

Published: January 2024

La juventud actual vive en plena revolución tecnológica, sobre todo, en el campo de la comunicación (chats, móviles, Messenger, etc.). En muchas zonas de España Internet ha superado a la televisión no solamente como espacio de entretenimiento en los adolescentes, sino también como agente de socialización. Los adolescentes hiperactivos o con Trastorno por Déficit de Atención con Hiperactividad (TDAH) poseen características específicas que pueden hacerles más vulnerables a la hora de utilizar las nuevas tecnologías, por ello, es importante investigar sobre los usos que hacen de Internet. En este trabajo se ha tratado de conocer, mediante la aplicación del Cuestionario de Hábitos Televisivos CH-TV 0.2, las posibles diferencias en el consumo de Internet, finalidad de uso y mediación parental de adolescentes con (TDAH) y estándar, con una muestra de 232 adolescentes del País Vasco.

Los resultados indican que existen diferencias en el perfil de consumo de Internet entre adolescentes con TDAH y adolescentes estándar. Son los primeros, en contra de lo hipotetizado, quienes hacen un uso inferior de Internet. Además, a pesar de que la principal finalidad de uso es la comunicación para ambas muestras, existen diferencias significativas entre ellas. Respecto a la mediación parental, son los adolescentes con TDAH los que afirman percibir en mayor medida la mediación instructiva y la restrictiva por sus progenitores.

Published: January 2024

Background: Older individuals are usually treated as a homogenous group despite evidence that old age consists of distinct subphases. This observational study including 493 older patients aimed to identify differences among age subgroups of older persons. Receiver operating characteristic (ROC) curve analysis was then applied to identify the optimal age cutoff points to distinguish those age groups. Methods: Data were collected on the demographics of older patients, their medical and medication histories, dependence on activities of daily living (ADLs), and instrumental activities of daily living (IADLs). Non-parametric tests (Kruskal–Wallis and Mann–Whitney U tests) and ROC curves were used for statistical analysis. Results: The 65–79 and ≥80 years of age groups showed distinct frailty status, comorbidity, and dependency in ADLs. The median age to remain completely independent in IADLs was 76–79 years, while the median age for being free from geriatric syndromes was slightly higher (77–80 years) and reached 82 years for the absence of delirium, falls, and swallowing problems. In the ROC analysis, the optimal cutoff ages for the presence of frailty, cognitive impairment, and dependency in ADLs were 80–82 years. Conclusion: The 65–79 and ≥80 years of age groups differed significantly in numerous parameters, underscoring the need to address these distinct age groups differently, both for applying medical therapies and interventions, as well as for conducting health research.
Dynamic Game Theoretic Electric Vehicle Decision Making
Authors: Ouyang Qianyu , Jia Xianzhe
Published: January 2024

Real-world driving in diverse traffic must cope with dynamic environments including a multitude of agents with uncertain behaviors. This poses a challenging motion planning and decision-making problem, as suitable algorithms should manage to obtain optimal solutions considering nearby vehicles. The state-of-the-art way of environment and action generalization is built on mathematical modeling and probabilistic programming of idealistic incidents. In this article we present dynamic anytime decision making, a decision-making algorithm that takes advantage of natural evolutionary and developmental processes to make decisions for an autonomous vehicle navigating in traffic. The methodology to achieve multidimensional judgment under unforeseen circumstances is to enable stochastic Bayesian game theory when modeling interactive properties and scenario estimation. In particular, we employ a dual-layer optimization strategy that substantially enhances the capability to extract mutual influence into decision matrix that organically synthesize decision rules according to encountered situations. Furthermore, our decision-making algorithm incorporates incremental capability that computes modified control variable due to unexpected vehicle behavior or intention. This results in improved performance gain where dynamic conditions receive reasoning with more effectiveness. We produce swift policy correction by leveraging previous game mechanism, where cooperative characteristics of both the controlled vehicle and other agents are integrated without computation overload. Aiming to reach utmost accurate decision, our reward function is reinforced with weight-tuning function to deduce optimal hyper parameters in a wider spectrum of vehicle scenarios. Through coupled decision tree optimization and incremental trajectory control, economical commands are computed with enhanced precision under complex traffic pattern. To this end, our system provides a robust framework in terms of handling dynamic vehicle interactive control, as decision is computed by synergy between progressive interface and external rationalization. We demonstrate the algorithm performing preeminent passing maneuvers and merging in a number of different simulated scenarios.
A Fast Charging Method for Lithium ion Batteries Based on a Unique Current Profile Method
Authors: S Manjunatha , K A Rakesh , Pratiwadibhayankaram Ashwini Kumar Krishnaswamy
Published: January 2024

The major constraint for consumers to shift from Internal combustion engines to Electric vehicles is the long waiting time to recharge their vehicles. With rapidly increasing interest for electric vehicles, there has been a need for fast charging systems to charge the lithium-ion batteries commonly used in all mobility vehicles. Not all Li-ion chemistry tolerate fast charging as it accelerates ageing leading to reduced life span and increases safety risk. The two main challenges faced to for developing fast charging are: requirement of complex charging electronic circuitry and suitable current profile to recharge the battery in shortest possible time. A common approach by researchers has been only to meet on any one challenge mentioned above. Only few attempts have been made to address both the challenges together. Therefore, in this work, we are presenting a unique fast charger that can adapt to the user needs and a unique current profile (UCP) to attain an efficient fast charging of Li-ion batteries. To evaluate the designed unique current profile concerning charging time and temperature increase the results are compared with the conventional charging technique i.e., constant current constant voltage (CC-CV). The results show that, the UCP technique applied on C/NCA Li-ion power optimised cells permits to recharge 80% of State of charge (SoC) in 45 minutes with a temperature elevation of 2°C beyond ambient temperature which is 4°C less than that of the conventional CC-CV protocol to recharge same amount of capacity. Ageing studies have been carried out and results show that the UCP technique preserves the life span of the batteries in comparison to conventional CC-CV technique.

Published: January 2024

Nowadays the EV car industry is getting more evolved, and OEMs are providing more autonomous and IoT features in the vehicle to provide more comfort to users. Government and local authorities are upgrading the charging infrastructure in the different areas of the cities like shopping malls and near petrol pumps. One of the problems with the EV vehicle is the charging duration, which is time-consuming. Each time a person visits a charging station, there is a probability that the charger would be occupied also human assistance is required to insert the charging gun into the vehicle. This paper proposes a smart parking ecosystem with induction chargers connected to a wireless network and gives an idea about how an EV vehicle is connected to the same network for information exchange between vehicles and wireless induction chargers. This paper discusses a situation in which, if all parking lots with chargers are occupied and the subject vehicle is parked within the geofence area without a charger, the vehicle will self-park whenever any charger becomes available for charging without human intervention. This paper also addresses minimum IoT and ADAS features needed in vehicles and authentication/permission required from the user side to use the facility.

To avoid issues with primary school pupils' sedentary lifestyle and fitness, it is important to evaluate how long they sit while studying in class. This study aims to ascertain 1) the impact of physical activity breaks on elementary school students' physical fitness, and 2) the variation in the improvement in physical fitness of elementary school students between the group with physical activity break intervention and the group without intervention. This is a quasi-experimental study with a Pretest-Posttest Control Group Design. The study's subjects were Yogyakarta Syuhada Mosque School elementary school children aged 7 to 9. The cluster random sampling method was employed to choose the research sample, with 40 students serving as the experimental group and 40 serving as the control group. A physical fitness test was used to collect data for this research. The paired T test was employed in the first analysis to examine the effect of physical activity break treatments on students' fitness. The Mann-Whitney Test was employed in the following data analysis to determine the difference in the outcomes of the rise between the experimental group and the control group. The results of the paired T test concluded that physical activity breaks had an influence on the dimensions of physical fitness which included the dimensions of speed with a value of sig 0.0, Agility sig 0.001, Arm Power sig 0.0, Leg Power sig 0.0, and flexibility sig 0.003. Based on the improvement results of each group, there were differences between the experimental group and the control group based on the Mann-Whitney Test sig value. Increase in speed sig 0.0, agility sig 0.032, arm power sig 0.0, and leg power sig 0.02. There is no difference in the flexibility dimension between the experimental group and the control group with a sig value of 0.908. Effect size with Cohen's formulation and criteria for the experimental group in the dimensions of speed 1.16 (high), agility 0.59 (moderate), flexibility -0.51 (very low), arm power 1.55 (high), leg power 0.87 (moderate). Because of the good impact on the dimensions of physical fitness, physical activity breaks can be incorporated in primary schools. In this day and age, physical activity breaks could be a solution to students' low fitness and sedentary lifestyle issues.

Published: January 2024

A ocorrência cada vez mais frequente de episódios de seca severa e prolongada tem levado as empresas do setor florestal a buscar o desenvolvimento de materiais genéticos tolerantes à seca e com alta produtividade. Para isso, o setor tem utilizado o melhoramento genético florestal. Contudo, no âmbito florestal, o processo de melhoramento para obtenção dos genótipos desejados é mais demorado em comparação com o das culturas agrícolas. Este trabalho de pesquisa teve como objetivo reduzir o tempo necessário para a seleção desses materiais, aplicando técnicas de inteligência artificial (IA) para a classificação precoce de cruzamentos de eucalipto quanto à tolerância à seca e produtividade. Coletamos dados de campo de diferentes cruzamentos de eucaliptos em fases iniciais de desenvolvimento, obtidos por meio de um teste de progênies. Os dados incluíram a Área Foliar Específica, o Potencial Hídrico Foliar, a Área Foliar, a Largura e o Comprimento Foliar, o Incremento Médio Anual Volumétrico e imagens das folhas ao longo de 42 meses. Utilizamos esses dados como entrada nos modelos de IA para prever o comportamento dos materiais genéticos em relação à tolerância à seca e produtividade. Testamos dois grupos de modelos: os clássicos (Floresta Aleatória, Redes Neurais Artificiais, Máquina de Vetores de Suporte e XGBoost) e as redes neurais convolucionais (MobileNetV2, ResNet50 e Xception). Para os dados analisados, observamos que os modelos de redes neurais convolucionais são promissores, com o modelo Xception alcançando uma acurácia de teste de 72%. Esse resultado é importante, pois destaca a IA como uma ferramenta útil no processo de seleção precoce nos programas de melhoramento, além de demonstrar sua aplicação na previsão do comportamento de genótipos, utilizando características funcionais das folhas, que são obtidas de maneira mais rápida e simples.

This article is devoted to the practice of using the «competitive model» of replacing the head of local self-government. The authors examine the advantages and disadvantages of the use of competitive selection in the election of heads of municipalities. It is noted that the introduction of a «competitive model» of elections has significantly increased the influence of governors on the selection of heads of municipalities. Based on the conducted research, the results of its application and the nature of its influence on the formation of the personnel of the heads of urban districts and municipal districts of the Chelyabinsk region are studied. The assessment of the corps of heads of local self-government is given according to such parameters as: gender, age, type of education and experience in leadership work. A comparative analysis of the personnel composition of the heads of municipalities formed by the results of the municipal elections of 2015 and 2020 was carried out. The analysis of the parameters of the elected heads of municipalities made it possible to identify the selection criteria that guided the regional state authorities in the selection of candidates. The new competitive selection mechanism made it possible to nominate persons with work experience in municipalities, most of whom received legal and economic education, to the post of head, which had a positive impact on the renewal of the staff. Based on statistical and biographical data of the elected heads of local self-government, a collective portrait of the head of the municipality of the Chelyabinsk region was compiled.

This study represents the aerodynamic design of an Unmanned aerial vehicle intended for surveillance or agriculture with a maximum take weight of 125 kg. Weight estimation and constraint analysis were done based on the Mission profile. Design of Computer-Aided Design (CAD) models were generated for three different configurations using CATIA V5R20 as a high wing, mid-wing, and low wing. Flow analysis was done for the above configurations at various angles of attack. ANSYS 15 was used for the flow Analysis. A Tetrahedron element meshed the model with the minimum required orthogonal quality. Five microns were given to the initial layer height of the prism mesh. Spalart Allmaras model is used as the Turbulence model in the solver. The aerodynamic characteristics of the above configuration obtained from Computational Fluid Dynamics (CFD) results were compared with the DATCOM program and validated with the wind tunnel experimental test data. The open-circuited suction-type Subsonic wind tunnel was employed for the test. The aerodynamic properties for the angle of attack in the range of -2° to 14° angle of attack are calculated using a six-component balance. The study aims to find the Unmanned Aerial Vehicle (UAV) configuration based on the aerodynamic characteristics obtained from the CFD and DATCOM results. High-wing UAVs have better aerodynamic efficiency than the other two configurations.

One of the most crucial components in any industrial operation is energy. However, the supply is not limitless. One of the key ingredients in cement production is energy, whose cost share ranges from 8 to 15% of overall production costs in developed nations but is much more in undeveloped nations. Therefore, the objective of this extensive research was to carry out a thorough energy conservation audit at the Sheba leather factory, located in the city of Mekelle, in the north region of Ethiopia. The specific objective of this research was to analyse the patterns of power consumption, identify energy-saving techniques, as well as to propose energy-saving recommendations for their implementation. It was obtained using primary and secondary data from the industry personnel. As a result, a total of 19 recommendations for energy saving were found and were forwarded for consideration. These recommendations have the potential to save a total of about $ 29900 annually, but their implementation would cost close to $ 15900, with a payback period of seven months. These recommendations also cover the utilities of the boiler, motors, blower, air compressors, cooling tower, and lighting. In order to lower their energy use, economic benefits are also considered.
