Published: September 2024

This study examined the effects of an on field combined strength/speed/soccer training program on the physical performance of 20 male adolescent (age: 14.0 ± 0.7 years) soccer players, who were divided into an experimental and a control group (EG, CG). The EG players wore "weight shorts", with 300 gr of additional weight on each thigh and participated 2 times/week in a 12-week training intervention program. The CG followed the same training program without wearing the "weight shorts". The physical abilities were evaluated the week before (pre) and two days after the 12-week intervention training period (post) and the follow-up evaluation was performed 4 weeks after the post measurement. The measured parameters were: a) sprint/repeated sprint ability (straight and with 180º turns, RSA-best/mean/total), b) RSA fatigue-index, c) vertical jump ability and d) lower body maximal strength. The EG improved significantly more (p< 0.05) compared to the CG on 10-m-straight, 30-, 35-, 40-m with 180º turns RSAbest-sprints, RSA fatigue-index, squat jump, leg curl (single right/left leg) and in split squat (single right/left leg) 5RM load. Using special shorts with additional weights on the thighs during soccer training improved speed/RSAbest-times and fatigue-index, jump ability and lower limbs maximal strength in youth soccer players.

Authors: Sarkar Surojit , Dutta Sreejita , Chatterjee Subhra , Tiwana Kamlesh , Saraswat Sanjay
Published: September 2024

Introduction: Live high-train high (LHTH) is suggested to improve performance, especially maximal aerobic capacity through the hypoxic adaptation responses. The present study aims to determine the impact of LHTH protocol on cardio-respiratory variables, lactate response, iron profile indices, and lung function capacities to the performance enhancement of middle-long distance (MLD) runners. Methods: Seven MLD runners were trained LHTH for six weeks at 8000ft altitude. Cardio-respiratory variables (V̇O2max, VO2/HR, VEmax, HR response), lactate response, iron profile indices (Hb, iron, UIBC, TIBC, transferrin, EPO, ferritin), and lung function parameters (FVC, FEV1, FEV1/FVC, PEF, and VC) were measured via standard protocols. Result: Hemoglobin (Hb, 7.8%), iron concentration (36.7%), and TIBC (8.2%) were found to be significantly increased after LHTH. On the other hand, V̇O2max (6.4%) and PEF (10.7%) were found to be significantly (p < 0.05) increased after camp. But HRrest (1.8%), HRrec (5min and 10min with 2.3% and 4.7% respectively), and lactate peak (7.9%) significantly decreased after LHTH condition. Discussion: All participating athletes improved performances after LHTH (overall group improved by 1.7%, individual increase up to 2.6%). Specific training load with hypoxic stress at high altitude induces peripheral chemoreceptor activation and stimulates sympathetic drive to initiate adaptive cascade leading to V̇O2max improvement (improved group mean 6.4%, individually up to 16.7%) which might be supported by enhanced erythropoiesis, iron metabolism, Hb concentrations, peak expiratory flow, glycolytic enzyme activity, enhanced oxidative capacity, improved resting and recovery HR response and peak lactate tolerance.

Authors: Xu Liang , Song Zhiguo , Chen Hongkun , Li Yongjin , Li Jingwei , Li Ruchun
Published: September 2024

Hydrogen (H2) plays a crucial role in the transformation of the energy structure due to its environmental friendliness, renewability and high energy density. The photocatalytic and electrocatalytic hydrogen evolution reaction (HER) presents a promising approach for H2 production. Molybdenum disulfide (MoS2) has emerged as a promising catalyst in photocatalytic and electrocatalytic HER due to its high activity, easy preparation and cheapness. However, it suffers from poor stability and inactive basal planes. In this review, we encapsulated the research advancements of MoS2 for photocatalytic and electrocatalytic HER in the past ~10 years. The latest strategies to enhance the catalytic activity of MoS2, such as doping, phase adjustment, surface modification and others, are also summarized. The relationship between structure and activity for enhanced H2 generation by different means is briefly introduced. The challenges and directions of MoS2 materials in photocatalysis and electrocatalysis for HER are also discussed, aiming to provide promising guidelines for future research.
Practical Nursing Judgment: A Moderate Realist Conception
Authors: Kikuchi June F. , Simmons Helen
Published: September 2024

Under the influence of idealist mainstream thinking that reality is mind-dependent, many nurses are dismissing the possibility of attaining objectively true judgments. A worrisome trend that has emerged from such thinking is to recommend that nursing practice decisions ultimately be basedsolelyon subjective judgments. We present a conception of practical nursing judgment based on the common-sense philosophy of moderate realism, which has the potential to help offset the trend. It allows for nursing decision making in which nursing principles and rules are modified in light of the contingent circumstances of a nursing situation, resulting in decisions which have both a subjective and an objective aspect to them. This feature, plus the fact that the nursing principles are grounded in common natural needs, rights, and obligations, provides nurses with a basis for nursing care which is individualized, just, benevolent, and sensible, a means requisite to making our lives good.
Relational Narrative: The Postmodern Turn in Nursing Ethics
Authors: Gadow Sally
Published: September 2024

A philosophy of nursing requires an ethical cornerstone. I describe three dialectical layers of an ethical cornerstone: subjective immersion, objective detachment, and relational narrative. Dialectically, the move from immersion to detachment is the turn from communitarian to rational ethics, replacing traditions with universal principles. The move from universalism to engagement is the turn from rational to relational ethics, replacing detached reason with engagement between particular selves. Conceptually, the three layers correspond to premodern, modern, and postmodern ethics. I propose that the layers be viewed not as stages, but as elements that coexist in an ethically vital profession, and I conclude with an illustration of their coexistence in a clinical situation.
Las mujeres en el sistema telegráfico en Colombia: asomos a la capacitación técnica, 1870-1930
Authors: Pita Pico Roger
Published: September 2024

El artículo analiza la inserción de las mujeres en el sistema de capacitación telegráfica en Colombia entre 1870 y 1930. A partir de la revisión de informes oficiales y publicaciones especializadas, el objetivo es ver cómo durante el régimen del liberalismo radical se ampliaron las oportunidades de género en el acceso a la educación en este innovador servicio de comunicación, lo cual significó un asomo a las ciencias y a la técnica. A la primera escuela fundada en Bogotá por el gobierno se sumaron otras a nivel regional y los espacios de formación extendidos a instituciones como las escuelas normales y las escuelas de artes y oficios. Las estadísticas disponibles indican que las estudiantes asimilaron los conocimientos técnicos y fueron altamente competitivas logrando proyectarse en la docencia y en la producción del conocimiento. Con ello, adquirieron instrucción técnica que les permitió incursionar laboralmente en esta área, aunque no dejaron de observarse algunas inequidades en materia de género y reacciones de algunos sectores conservadores que se acentuaron en el periodo de la Regeneración.

Published: September 2024

Background: Tuberculosis (TB) is an infectious disease caused by the Mycobacterium tuberculosis. The countries with the third highest TB cases worldwide are India, China, and Indonesia. A decrease in stamina will occur in a person suffering from tuberculosis. Purpose: This study was conducted to determine the relationship between nutritional status and suspected new TB cases in junior high school students in the working area of Puskesmas Keputih Surabaya. Methods: This study was conducted with a cross-sectional study design in the working area of Puskesmas Keputih in 2023. Secondary data was obtained from Keputih Health Centre in 2023. The research sample used a total sampling population. The association between nutritional status and suspected new TB cases in junior high school students was tested using the chi-square method. Results: A chi-square test was conducted on high school students and found no significant association between nutritional status (underweight and average weight) and TB screening or suspected new TB cases (PR = 0.68, p-value = 0.16). In addition, it was also found that there was no significant association between nutritional status (overweight and average weight) and TB screening or suspected new TB cases (PR = 1.01, p-value = 1.00). Conclusion: There was no significant association between nutritional status and the incidence of new suspected tuberculosis in junior high school students. This indicates that other risk factors also play an essential role in influencing a person's immune system.

Change in community behaviour in supporting sustainable development: The case of the biogas program in Ponorogo Regency
Authors: Agustin Dinda Putri , Nurwati Nunung , Lesmana Aditya Candra
Published: September 2024

The change in community occupation to dairy farmers and the increase in the number of livestock have caused environmental problems. This research focuses on the program’s function on changing the behaviour of the community in disposing of dairy cow manure from the phase of throwing it into the ditch to the phase of processing the manure into the biogas. This research was conducted using qualitative methods, with data collection techniques carried out through in-depth interviews, observation, documentation and literature review. The biogas problem launched by the government has proven to be able to change communities behaviour in the disposal of dairy cows manure. After receiving the biogas program, the community processed the cow dung into biogas. Interestingly, the factor that contributed the most to this behavioural change is economic. This shows that the social, environmental, and economic system have related functions and cannot be separated from each other in society. There is not much research on community behaviour change that is affected by environmental sanitation and motivated by economic factors. This study also alludes to the potential for corruption in the program. This study concludes that the biogas program is able to provide opportunities for the community to save on purchasing household fuel and minimize the waste of dairy cow waste into rivers. Apart from that, the biogas program could be a consideration for the government in creating new programs related to environmental sanitation, especially in the rural livestock industry.

Published: September 2024

Septic arthritis is a joint inflammation caused by an infectious agent. Septic arthritis takes a long time to heal, and as such it may have a significant economic impact. A one-month-old Friesian Holstein calf was lame and had swelling in the left carpal joint. Synovial fluid samples from the left carpal joint were used for bacterial identification, which use API Strept 20 (bioMérieux, Inc – USA). The identification results showed that septic arthritis was caused by Streptococcus dysgalactiae subspecies dysgalactiae,. Streptococcus dysgalactiae subspecies dysgalactiae play a significant role even though it plays a major role in mastitis in dairy cows.

Published: September 2024

В статті представлено характеристики моделі завмирання з Фішер–Снедекор (F) розподілом для забезпечення комбінованого рознесення сигналів SC (selection combining) в обмеженій системі під дією завад. Приведені функція щільності ймовірності PDF (probability density function) і кумулятивна функція розподілу CDF (cumulative distribution function) без SC рознесення при заваді від одного користувача. Також розраховано вирази CDF і PDF при використанні SC рознесення. PDF представлено для різних комбінацій параметрів корисних сигналів та параметрів багатопроменевого завмирання сигнала перешкод. Результати також проілюстровано в залежності від ймовірності порушення зв’язку OP (outage probability) як для незалежних, але не обов’язково ідентично розподілених INID (independent but not necessarily identically distributed), так і для незалежних ідентично розподілених IID (independent identically distributed) каналів.

В статті досліджується ефективність низхідної системи неортогонального множинного доступу NOMA (non-orthogonal multiple access) з використанням схеми стекової довгої короткотривалої пам’яті S-LSTM (stacked long short-term memory), що базується на глибокому навчанні DL (deep learning). Вважається, що канал зв’язку між автомобілями V2V (vehicle-to-vehicle) є селективним за часом внаслідок мобільності вузлів та наявності неточної інформації про стан каналу CSI (channel state information). Використання моделей незалежних та ідентично розподілених IID каналів (independent and identically distributed) з завмираннями п’ятого покоління (5G) на основі ліній затримки типу C TDL-C (tapped delay line type C) дозволяє створювати відгалужувачі каналів, які належним чином відтворюють бездротовий канал з завмираннями Nakagami-m. У статті досліджено ймовірність відключення OP (outage probability) та частоту символьних помилок SER (symbol error rate) як традиційних, так і запропонованих канальних оцінювачів. В статті проаналізовані ці характеристики при різних параметрах завмирання, пілотних символах PS (pilot symbols), швидкості навчання LR (learning rate) та розмірах пакетів. Навчання моделей глибоких нейронних мереж DNN (deep neural network) виконано за допомогою оптимізатора Adam. Підвищення відношення сигнал/шум SNR (signal-to-noise ratio) може зменшити SER, а отже, покращити ідентифікацію каналу низхідної лінії зв’язку в системах на основі стільникових мереж NOMA. Зменшення LR позитивно впливає на SER, підтверджуючи аналітичні висновки, які вказують на більші зміни у вагах DNN і більші помилки валідації при збільшенні LR. Проте ця перевага супроводжується недоліком частішого оновлення, що призводить до затримки збіжності моделі.

У статті розглянуто особливості акустооптичної взаємодії в контексті детектування імпульсного сигналу. Обґрунтовано актуальність розробки більш простого методу, придатного для розрахунку параметрів вихідного сигналу демодулятора при подачі на його вхід імпульсного сигналу. На основі геометричного представлення фотопружної взаємодії складено апроксимаційні моделі модулюючого імпульсу та імпульсу на виході фотодетектора. Показано, що основним параметром, що впливає на форму вихідного імпульсу, являється інерція акустооптичного демодулятора. Постулюється, що цей параметр формується за рахунок впливу двох факторів: просторово-часових параметрів акустооптичної взаємодії та інерції фотодетектора. Для оцінки ступеня впливу цих факторів проведено чисельний аналіз на основі збудованих моделей. Результати теоретичних досліджень та чисельного аналізу підтверджені експериментальними дослідженнями. Встановлено, що з використанням швидкодіючого фотодетектора інерція акустооптичного демодулятора переважно визначається просторово-часовими параметрами акустооптичної взаємодії.

В статті розглянуто смуго-пропускний фільтр N-го порядку (СПФ), який має змішані зв’язки між усіма сусідніми резонаторами, а також між кінцевими резонаторами та навантаженнями. Така комбінація зв’язків забезпечує (2N + 1) нулів передачі (НП) на реальних частотах. До існуючих (N + 1) НП, створених змішаними зв’язками, додається ще N НП, які сформовані резонаторами зі спеціальними властивостями. Кожен такий резонатор є λ/4-резонатором, в якому точка підключення розташована відносно близько до короткозамкненого кінця. При такому зв’язку вхiдна провiднiсть резонатора Y(jω) має полюс ωp, який розташований праворуч і на невеликій відстані від основної резонансної частоти ω0. Цей полюс ωp функції Y(jω) призводить до появи правого НП у СПФ. Якщо використати N резонаторів з різними точками підключення, то на характеристиці СПФ з’явиться N додаткових НП. Приведена конструкція такого СПФ. Представлено виміряні та змодельовані частотні характеристики СПФ другого порядку з п’ятьма НП.
Public Animo in the 2020 Gubernatorial Election in Central Kalimantan during the Covid-19 Pandemic Era: Religious and Cultural Approaches

Published: September 2024

Many observers believe that holding general elections during a pandemic is ineffective in attracting public interest, including in Central Kalimantan. This study aimed to examine how the public's animo in the gubernatorial election during the Covid-19 pandemic, through religious and cultural approaches, in which the Central Kalimantan people still respected traditional and religious leaders as role models. This research used descriptive qualitative data collected through interviews with traditional and religious leaders and related documents obtained from election administrators. The findings showed that socialization was a reasonably good tool and strategy carried out by traditional leaders and religious leaders at specific events with cultural (local tradition, Dayak language) and religious approaches (through speech in churches and other religious places of worship). Socialization by traditional and religious leaders contributes to public animo in the gubernatorial election in Central Kalimantan.
God’s Certainty-Uncertainty Principle versus Heisenberg’s Uncertainty Principle: A Possible Path to Unification of Gravity and Quantum Mechanics
Authors: Haug Espen
Published: September 2024

Einstein was skeptical of part of quantum mechanics, and he believed that Heisenberg’s uncertainty principle did not reflected the full depth of reality. He famously stated, ”God does not play dice with the universe.” However, since quantum mechanics has passed so many experimental tests, most physicists today assume that Einstein was wrong. Nevertheless, we will demonstrate that Heisenberg’s uncertainty principle must be modified to unify gravity with quantum mechanics. This modification leads to the Certainty-Uncertainty principle where the certainty part is strongly linked to gravity. This means Einstein likely was right in his intuition also on this point. The key is to understand that the de Broglie wavelength is not the actual wavelength of matter but merely a derivative of the true matter wavelength, namely the Compton wavelength. Furthermore, one must understand that the gravitational constant, first introduced in 1873, is simply a composite constant needed to rectify the incomplete definition of kilogram mass introduced into Newtonian gravity in 1873.
Embodying Vulnerabilities and Emotions in the Analysis of Political Hate and Threats: The Case of Nasty Rhetoric in Swedish Climate Politics
Authors: von Malmborg Fredrik
Published: September 2024

In this paper I dig deep down along the slope of what touches me deeply – a democratic decline in climate politics. I follow the course of critical researchers in management and organisation studies, striving to move away from traditional, horizontal norms of academic writing that focus on counting rather than content and elision the author from the text, towards a more vertical writing acknowledging the value of incorporating the voice of the author. Embodying and resonating with my own emotional experiences of hate and threat campaigns, not locking my own vulnerabilities in, I analyse qualitatively the use, reasons, contents, senders and targets of such nasty rhetoric in Swedish climate politics, and the implications thereof for democracy. At the moment, a far-right populist nativist party holds tangible powers dictating the content and process of Swedish climate politics. In less than two years, Swedish climate politics have turned into an antidemocratic divisive politics portraying climate science as “a point of view”, female journalists writing about climate change and climate policy as “crypto environmentalists”, “motherfuckers” and “moron hags” that should be “fired” and “raped”, and the climate justice movement as “terrorists” and “a threat to Swedish democracy” that should be “sent to prison” and “executed”. Such nasty rhetoric is used not only by anonymous trolls in social media, but by the prime minister, cabinet ministers and parliamentarians, even in debates in the Swedish parliament. It has inspired the far-right extremist movement to use physical violence. Use of nasty politics aims to silence the opponents to the government’s climate policy, the political opposition, climate scientists, the climate justice movement and journalists, breaching liberal and deliberative democratic norms such as legitimacy, accountability and justice. It is a powerful tactic that leaves its targets with an anxious fear of losing control and often a need for disappearance. Many targets resign or stay silent. I chose to break the silence and write differently about the issue.

Plant diseases not only cause economic losses, but they also pose a health risk. In this regard, aflatoxins are linked to the development of some type of liver cancer, especially the hepatocellular carcinoma. Aflatoxins are usually produced by the fungi Aspergillus flavus and Parsiticus in figs, and their identification is usually carried out using invasive and complex methods or by visual inspection at an advanced stage. Given that Spain is one of the main producers of figs and Extremadura is the leading region in the country, it is necessary to explore alternative ways of detecting the presence of aflatoxins in figs and preventing them from entering the food chain. The aim of this research is to address the early detection of Aspergillus flavus fungus using non-invasive techniques with the aid of hyperspectral imaging and the application of artificial intelligence techniques, in particular deep learning. The images were taken after inoculation of the microtoxin using 3 different concentrations, related to three different classes and healthy figs (healthy controls). The analysis of the hyperspectral images was performed at the pixel level. Firstly, a full connected neural network was used to analyse the spectral signature associated with each pixel; second, the wavelet transform was applied to each spectral signature. The resulting images are fed to a convolutional neural network. The hyperparameters of the proposed models were adjusted based on the parameter tuning process also performed. The results are promising, with 83% accuracy, 82.75% recall and 83.25% F1-measure for the single neural network, and 77.25% accuracy, recall and F1 for the convolution neural network.
Stochastic Decision-Making Optimization Model for Large Electricity Self-Productors Using Natural Gas in Industrial Processes: An Approach Considering a Regret Cost Function

Published: September 2024

In the context of high energy costs and energy transition, the optimal use of energy resources for industrial consumption is fundamental. This paper presents a decision-making structure for large consumers having flexibility to manage electricity or natural gas consume to satisfy the demands of industrial processes. The proposed modelling energy system structure relates monthly medium and hourly short-term decisions to which these agents are subjected, represented by two connected optimization models. In the medium term, the decision occurs under uncertain conditions of energy and natural-gas market prices, as well as hydropower generation (self-production). The monthly decision is represented by a risk-constrained optimization model. In the short term, hourly optimization considers the operational flexibility of energy and/or natural-gas consumption, subject to the strategy defined in the medium term and mathematically connected by a regret cost function. The model application of a real case of a Brazilian aluminum producer indicates a measured energy cost reduction of U$ 3.98 million over a six-month analysis period.

Elucidating the z-dependence of the MOND acceleration (a0) within the Scale Invariant Vacuum (SIV) paradigm
Authors: Gueorguiev Vesselin G.
Published: September 2024

In a recent paper: “On the time dependency of a0” the authors claim that they have tested “one of the predictions of the Scale Invariant Vacuum (SIV) theory on MOND” by studying the dependence of the Modified Newtonian Dynamics (MOND) accelera- tion at two data sets, low-z (3.2 × 10−4 ≤ z ≤ 3.2 × 10−2) and high-z (0.5 ≤ z ≤ 2.5). They claim “both samples show a dependency of a0 from z”. Here, the work men- tioned above is revisited. The explicit analytic expression for the z-dependence of the a0 within the SIV theory is given. Furthermore, the first estimates of the Ωm within SIV theory give Ωm = 0.28 ± 0.04 using the low-z data only, while a value of Ωm = 0.055 is obtained using both data sets. This much lower Ωm leaves no room for non-baryonic matter! Unlike in the mentioned paper above, the slope in the z- dependence of A0 = log10(a0) is estimated to be consistent with zero Z-slope for the two data sets. Finally, the statistics of the data are consistent with the SIV predic- tions; in particular, the possibility of change in the sign of the slopes for the two data sets is explainable within the SIV paradigm; however, the uncertainty in the data is too big for the clear demonstration of a z-dependence yet.
Prajna-Paramita-Hridaya/the Heart Sutra: Bhagavati, the Heart of Transcendental Knowledge
Authors: Sinha Shriprakash
Published: September 2024

The essence of the sutta that is often stated as the heart sutta or the prajna-paramita, is the wisdom related to the absolute truth or the paramartha, that is experienced in the heart. It is referred to as the foundation stone of the Mahayana Buddhist teachings but in a grander aspect of the nature, truth can neither be labeled as buddhist or hindu or islamic or christian or sikh or tao or zen or parsi or quantum or social etc. When one meditates the identifications dissolve. It would be wrong for anyone to say that she/he would be a buddhist when her/his individuality is lost in emptiness during meditation. What remains is awareness and in awareness, all grasping and feverishness is lost. This knowledge which makes one transcend into the realms of Buddhahood or completely liberated state is revered as goddess also and given a name Bhagavati. So the mother of all Buddhas or the completely liberated ones is nothing but the absolute truth that is encased in the prajna-paramita-sutta. One is raising the female aspect of nature on a higher citadel and terming it as the mother of all Buddhas. Experiencing the absolute truth in heart takes time but it is packed into a verbalized contorted form of a few words. The sutta tries to capture the un-captured absolute and gives a way to explore the deeper realms of the truth at an experiential level. Note that both the former Buddha and the bodhisattva-mahasattva enter into emptiness, experience the knowledge in their entire mind-body complex and after the experience Siddhartha raises Avalokiteshvara to a higher platform and asks him to impart the experienced knowledge in a few words. After the teaching finishes, the Buddha puts a seal on what the bodhisattva has taught by saying "Well done! This is how it should be taught." One has experienced knowledge but one needs a seal of confirmation. The relevance of this knowledge is inexplicable given the magnanimity of conflicts and clashes that happen in the mind body complex pertaining to the spiritual journey one takes. The knowledge is of immense value to those who have experienced deep conflicting issues in their hearts, that have perturbed them regarding the subtle aspects of a spiritual journey. Prajna-paramita-sutta aims to assuage the deeper issues that troubles the heart of a spiritual seeker and makes the path easy enough to reach the goal. The Heart sutra contains the Mahasattipatthan sutra.

Published: September 2024

The rising challenge of polyethylene terephthalate (PET) waste necessitates efficient collection methods to mitigate environmental impacts. The Analytic Hierarchy Process (AHP) is one of the Multi-Criteria Decision Analysis (MCDA) approaches utilized in this study. The Technique for Order of Preference by Similarity to the Ideal Solution (TOPSIS) was used to rank each alternative according to the objective weight that AHP had produced. Also, sensitivity analysis was performed to determine how robust the findings were when considering equal weights and entropy weights to maximize PET waste collection techniques. The alternative achieved the objective of obtaining the best collection method, Threshold Plastic Bottle Waste Collection (Tpbw), out of all the three alternatives considered. Another MCDA approach, VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR), was used to compare the results and validate the ranking result achieved by the TOPSIS method. The VIKOR technique's validation of the TOPSIS approach showed that the outcomes were highly consistent. Data for the study were gathered from the archives of waste management companies on possible practices of plastic waste collection addressing costs, environmental impacts, social acceptance, feasibility, and efficiency. The findings provide a prioritized framework for enhancing PET waste collection strategies, contributing to sustainable waste management. Many criteria are considered when deciding the best collecting method for PET waste recycling, making it challenging. By using criteria importance, multi-criteria decision analysis (MCDA) was applied in this study, and the objective weight of the criteria was determined using the analytic hierarchy process (AHP). The five criteria considered in this study are Initial investment cost, Operational cost, Transportation cost, Environmental risk, Employment potential, and the objective weights allocated to them. AHP results 0.4952, 0.1997, 0.1565, 0.0870, and 0.0616 are respectively determined.

The bimetallic (Ta/(Ti, V, Co, Nb) mesoporous MCM-41 nanoparticles were obtained by direct synthesis and hydrothermal treatment. The obtained mesoporous materials were characterized by XRD, XRF, N2 adsorption/desorption, SEM, TEM, XPS, Raman, UV-Vis, PL spectroscopy. A more significant effect was observed on mesoporous structure, typi-cally for MCM-41, and optic properties if the second metal (Ti, Co) does not belong to the same Vb group with Ta as V, Nb. The obtained new nanoparticles were used as catalysts for oxidation with H2O2 of olefinic compounds (1,4 cyclohexadiene, cyclohexene, styrene) and photodegradation of organic pollutants (phenol, methyl orange) from water. The re-sults showed improving of activity and selectivity in oxidation reactions by addition of the second metal to Ta-MCM-41 catalyst. The slow addition of H2O2 was also be benefit for the selectivity in epoxide products and stability of the catalysts. The band gap energy values decrease in the presence of the second metal and the band edge diagram evidenced posi-tive potential for all the conduction band of the bimetallic samples except TaTi-MCM-41. The higher photocatalytic degradation was obtained for samples with TaTi and TaV.
