Published: January 2025

This investigation was undertaken in Jaipur district of Rajasthan with a view to identify the factors affecting the farmer’s choice of specific dairy outlet to sell their marketable surplus. The data were collected from a sample of 80 sample respondents selected through multistage purposive sampling for the year 2021-22. A tabular analysis was done to list prevalent marketing channels and then a multinomial logit model was fitted to identify the factors affecting farmer’s decision of choosing a particular milk-marketing outlet. The farmers used one of the three marketing channels to deliver milk to final consumers. Channel-I was direct marketing channel (Producer – Consumer) and channel II(Producer - Milk vendor- Consumer), channel III (Producer –Collection centre – Co-operative milk plant – Consumer) were indirect marketing channels of milk. The Channel-III was the most preferred channel of milk marketing, as it was opted by 47.50 percent of the total farmers. Multinomial logit (MNL) regression’s results indicated that herd size, marketable surplus, caste categories, access to institutional credit, BPL economic class, income from livestock and breed type of animals were the seven significant factors affecting farmer’s decision of choosing a particular milk-marketing outlet out of three. Although direct marketing channels are highly efficient and fetch more prices to producers, still most of the farmer choose channel III for marketing of milk, may be because of easy disposal of marketable surplus. This trend might continue, therefore, farmers should be made aware about quality parameters like fat percentage in the milk, or even provided with affordable fat testing kits through Pashu Vigyan Kendras/ Extension centres like KVKs, so that farmers can test it at their level and be assured about the prices they receive in the collection centres. There is need for the effective and improved spread of modern market outlets and dairy cooperatives, so that all the farmers irrespective of social and economic background may benefit from livestock farming.

Global warming and its concomitant changes in mean climate variables and climate variability have an impact on animal feed and fodder, animal health, production, and water availability. Buffaloes are the mainstay of the Indian dairy economy and the backbone of the rural economy and dairy industry in the Haryana state in particular. Murrah buffalo-based production system has to be imparted the ability to withstand the adversities associated with climate change as well as to maintain their productivity. Therefore, the present study was undertaken to develop climate services and analyze their impact on Murrah buffalo farmers’ operational decision-making related to dairy farming. The study was conducted in the Hisar, Jind, and Rohtak districts of Haryana state. Two blocks were selected randomly from each district and from each block three experimental villages and one control village were selected, resulting in 18 experimental and 6 control villages in total. The three experimental villages of each block were randomly assigned to the intervention mode of either WhatsApp, Text SMS, and Mobile application which was exclusively developed for the present study thus resulting in 6 villages each receiving treatment through WhatsApp, Text SMS, and Mobile application. From each village, 15 farmers were selected randomly and provided with treatment i.e., weekly THI-based Murrah buffalo climate service module. The findings of the study revealed a positive treatment effect of the climate services on variouspractices like the adoption of improved varieties of fodder, and nutrition management through the inclusion of oilcake, miner mixture in animal diets. The adoption of rubber mats, providing chopped fodder, use of bedding materials and covering open spaces of the animal shed during winter, the practice of deworming the herd and maintenance of cattle shed hygiene, and others. Hence, the climate services for Murrah buffalo farmers were found to be a potential adaptation tool to enhance the resilience capacity of vulnerable dairy farmers to adapt to climate change.

Published: January 2025

Yoghurts are those milk products which are fermented and have a good impact on the human health. Incorporation of herbs or medicinal plants into the yoghurt, can improve the variety as well as the nutritional and therapeutic benefit of the yoghurt. The present study aimed at developing yoghurt incorporated with betel leaf extract and was successful. The incorporation of15% betel leaf extract had better organoleptic qualities when compared to the other treatments. The selected yoghurt was stored for 15 days in refrigerated condition and was subjected to organoleptic and nutritional evaluation. The organoleptic scores gradually decreased during storage. Physico-chemical parameters such as moisture, water holding capacity, and syneresis were significantly decreased as the storage period increased. The nutritional components such as energy and carbohydrate were also significantly different as the storage period was extended. Further studies have to be carried out to understand the shelf stability and medicinal properties of the prepared yoghurt.

Development of a technique to detect the presence of cow milk in goat milk
Authors:   Vandhana P S and Divya M P
Published: January 2025

Adulteration of Goat milk in terms of mixing with Cowmilk has emerged to be a serious issue in the recent years. The higher price and nutritional value coupled with limited availability of the former serves as the driving factor for the mixing of relatively cheaper, easily available cow milk to goat milk. The current available analytical techniques for the detection of presence of cow milk in goat milk are highly sophisticated, complex and time consuming which cannot be adopted at the basic level by private goat milk producers. So, the development of a simple rapid laboratory technique for the same which can be applied at the farm and society level is a need of the hour. This study was conducted using pure goat milk, pure cow milk and cow milk mixed with goat milk at different proportions of 25%, 50 % and75%. The physico chemical and compositional properties of samples were analysed and a significant variation between the samples was observed in terms of fat and chloride content. The ethanol stability was checked for the samples and found out that goat milk has lower ethanol stability compared to bovine milk and it improved by addition of cow milk. A blue colour which varies proportionately in intensity from light blue for pure goatmilk to dark purple by increased addition of cow milk was observed by addition of Bromocresol purple and was verified using Hunterlab colorimeter. The addition of Seliwanoff’ s reagent to the above said samples led to the development of coagulum with significant differences in appearance such as a completely dispersed coagulum in case of goat milk and a clearly settled coagulum on top portion for cow milk. The rate of settlement of coagulum to the top increases with increase in content of cowmilk in goat milk. The above stated differences may be considered as the basis for detection of presence of cow milk in goat milk. Further the Scanning Electron Microscopic study of coagulum was carried out and fatty acid profile of samples was analysed using GC-MS, which finally confirmed our results. This led to the development of a rapid test for detection of inter- species adulteration of goat milk with cow milk.

A importância da qualidade do sono no desempenho operacional de policiais militares e a necessidade de otimização nas escalas de serviço
Authors: Martins Lucas Augusto Guimarães
Published: January 2025

O sono é um fator crítico para a saúde física e mental, impactando diretamente o desempenho cognitivo e a capacidade de tomada de decisões. Isso é especialmente relevante para profissões de alta responsabilidade, como a Polícia Militar, que exige constante vigilância, atenção a detalhes e respostas rápidas em situações de estresse. Este artigo explora a relação entre a qualidade do sono e o desempenho operacional dos policiais militares, destacando a necessidade urgente de otimização das escalas de serviço dentro dessa instituição. A revisão da literatura científica revela que a privação de sono está fortemente associada a consequências adversas, incluindo aumento dos níveis de estresse, diminuição da capacidade de reação, falhas na tomada de decisões e maior risco de envolvimento em acidentes. Além disso, a fadiga excessiva pode prejudicar a saúde mental e física dos policiais, impactando sua capacidade de cumprir suas funções com eficiência e segurança, bem como a saúde física e mental dos agentes a longo prazo. Casos reais são apresentados para ilustrar como a falta de sono pode resultar em falhas operacionais e comprometer a integridade dos profissionais e da comunidade que atendem. A partir da análise das escalas de serviço da Polícia Militar do Estado do Paraná, o artigo propõe diretrizes para a reformulação dessas escalas, com a intenção de criar um ambiente de trabalho mais equilibrado e saudável para os policiais. A implementação de modelos mais adequados de turnos de trabalho, com períodos de descanso regulares e estratégias de conscientização sobre os impactos da privação de sono, pode ser uma solução viável para melhorar tanto o bem-estar dos policiais quanto a segurança pública como um todo. Este estudo contribui para a discussão sobre como a gestão do tempo de trabalho nas forças de segurança pode ser aprimorada, com foco no cuidado da saúde dos profissionais e na melhoria de seu desempenho operacional.
Modification of a silicate xerogel with cetyltrimethylammonium bromide for the adsorption of tartrazine yellow dye
Authors: Buzato Gabriel Vinicius , Daniele Giovanni Gomes , Souza Adriano Lopes de
Published: January 2025

Synthetic dyes present in industrial wastewater cause adverse effects on aquatic organisms and humans. Tartrazine yellow (TY) is an anionic dye used in textiles, cosmetics, and food industries, which has adverse effects on diet consumption. An alternative method for removing residues from wastewater is the adsorption process using silica xerogels. Though the use of silica materials as adsorbents of dyes has already been studied, xerogels used for this purpose have not yet completely known. The work reported here describes the study of the adsorption capacities of two silica xerogels, prepared by the sol-gel method via acid catalysis, for TY from its aqueous solutions. These two silica xerogels were synthesized using tetraethylorthosilicate as a precursor. The first was named silica xerogel unmodified (SiO2-UN), and the second was modified with a surfactant, cetyltrimethylammonium bromide (CTAB), named SiO2-CTAB. The adsorption process was realized using Ultraviolet-visible spectroscopy. The pseudo-second-order model best described the adsorption kinetics. The equilibrium data fit well to the Freundlich adsorption isotherm for SiO2-UN while for SiO2-CTAB, the results best fitted to the Langmuir isotherm model. SiO2-CTAB had a higher maximum adsorption mass value of 9,62 mg g-1 for TY than SiO2-UN, which could be attributed to electrostatic interactions. The results indicate the potential use of SiO2-CTAB as adsorbent for TY.

Published: January 2025

Introduction: The treatment of chronic testicular pain is a complex condition that will be encountered by most practicing clinicians. In this study, the influence of low-level laser irradiation of the red and infrared spectral range for treating chronic testicular pain was evaluated and compared. Methods: In this double-blind, placebo-controlled randomized clinical trial study, 60 patients were randomly divided into three groups of 20: (1) low-level laser group with red (650 nm, 50 mW), (2) low-level laser group with infrared (820 nm, 100 mW) and (3) laser placebo group. The treatment protocol consisted of 15 minutes, three times a week, for only 12 sessions. Then the patients were evaluated for pain and sexual satisfaction during the follow-up. Results: There was a significant reduction in the pain score in the two groups of the low-level laser group with red (650 nm, 50 mW) and the low-level laser group with Infrared (820 nm, 100 mW) spectra compared with the control, at 6 and 12 weeks after the treatment (P<0.05). Also, the level of sexual satisfaction in the two groups of low-power laser with red and infrared spectra showed a significant improvement (P<0.05). Conclusion: Low-level laser therapy is a safe, noninvasive, and useful method for treating patients with chronic testicular pain. Therefore, red (650 nm, 50 mW) and Infrared (820 nm, 100 mW) spectra low-level laser therapies improve testicular pain and sexual satisfaction.

Published: January 2025

Introduction: Photoacoustic imaging (PAI) uses nonionizing radiation for tumor features and thus can be used as an alternative method for medical features without inducing biological effects. The study aimed to characterize a PAI system utilizing a 650-nm diode laser to detect pathological conditions (benign and malignant tumors) in human uterine tissue, including healthy tissue. The benign tumor tissue used is a leiomyoma, which is a benign tumor that occurs in the middle layer of the uterine (myometrium). Meanwhile, the malignant tumor tissue used is a type of endometrial carcinoma, which is a malignant tumor that occurs in the inner layer of the uterine (endometrium). Methods: The human uterine tissue was obtained from the hysterectomy procedure conducted to determine the histopathological diagnosis. The PAI system uses a condenser microphone as the acoustic signal detector and a diode laser as the radiation source. Results: The characterization results of the PAI based on a diode laser with a wavelength of 650 nm and power of 250 mW showed an optimal performance for human uterine tissue in a laser modulation frequency of 16500 Hz and a duty cycle of 50%. Obtained photoacoustic images could differentiate between healthy uterine, leiomyoma, and endometrial carcinoma tissues, as indicated by the intensity level values in each tissue type. Healthy uterine, leiomyoma, and endometrial carcinoma tissues had intensity values of 11.87, 26.84, and 37.26 a.u, respectively. A One-way ANOVA test with Bonferroni post hoc analysis revealed a significant difference in the acoustic intensity level between the groups (P<0.05). Conclusion: The resulting intensity levels indicate a direct correlation with the nature of uterine tumors. The poorer the differentiation, the higher the resulting intensity.

Published: January 2025

Introduction: The relapse of rotated teeth is a significant concern in orthodontics, and circumferential supracrestal fiberotomy (CSF) presents a potential solution. Traditionally, CSF is performed using a surgical blade; however, employing a laser may reduce complications. This study aimed to systematically review the literature comparing laser-assisted CSF with conventional methods in orthodontic patients. Methods: A comprehensive search was conducted across the PubMed, Scopus, Web of Science, and Cochrane Library databases using a specific search strategy up to June 16, 2024. Data extraction was done in accordance with the defined inclusion and exclusion criteria. Results: Initially, a total of 293 articles were identified through the search process, and ultimately, four were selected for analysis based on specific inclusion and exclusion criteria. The studies involved various types of lasers including diode (810 to 940 nm), Er:YAG, and Er,Cr:YSGG lasers, and examined the effects of low-level laser therapy (LLLT) in conjunction with surgical interventions. Regarding relapse rates, two studies reported that both laser and surgical blade techniques demonstrated comparable efficacy, while adjunctive LLLT was effective in reducing relapse. In the other two studies, the use of laser therapy was found to be effective in decreasing relapse rates compared to the control group. Pain assessment results were inconclusive; one study reported reduced pain in the laser group, while another found no significant difference in pain levels between the laser and blade techniques. Furthermore, no significant differences were observed in periodontal pocket depth or gingival recession between the two methods. Conclusion: Within the limitations of the current systematic review, our findings indicate that there is no significant difference in relapse rates between laser and blade CSF procedures. Furthermore, our results suggest that the incorporation of photobiomodulation at higher doses is correlated with a reduction in relapse rates following fiberotomy procedures.

Published: January 2025

Introduction: White spots are a common complication of orthodontic treatment. Several prevention methods such as fluoride therapy and laser irradiation have been proposed, but there is still no conclusive evidence. Therefore, this study aimed to evaluate the combined application of diode laser and fluoride varnish in preventing white spots. Methods: Thirty-nine sound human premolars were extracted for orthodontic purposes and randomly divided into three groups of thirteen teeth each (C: Control, FV: fluoride varnish (5% sodium fluoride), and FV+L: fluoride varnish+980 nm diode laser (2 W)). The freshly extracted teeth were disinfected in a 0.5% chloramine T solution and stored in saline at room temperature. Each tooth was coated with nail polish, leaving a 2×3 mm2 window on the midbuccal. Surface treatments were applied, and primary Vickers microhardness was evaluated in the gingival sections. Then, the samples were immersed in alternating demineralizing (6 hours/day) and remineralizing (18 hours/day) solutions and incubated at 37 °C for 9 days to produce artificial caries. Afterward, the samples were immersed in a remineralizing solution for one day. Finally, secondary microhardness was measured. The data were analyzed using one-way ANOVA. Results: The primary microhardness was higher in groups C and FV than in group FV+L. The lowest secondary microhardness was recorded in group C, and there was no significant difference between the other two groups. The change in microhardness was greater in group C, while no difference was observed between the FV and FV+L groups. Conclusion: Within the limitations of this study, the combined application of laser irradiation and fluoride varnish may not improve white spot lesion (WSL) prevention compared to the use of fluoride varnish alone.
Detection and Characterization of Low Probability of Intercept Triangular Modulated Frequency Modulated Continuous Wave Radar Signals in Low SNR Environments using the Scalogram and the Reassigned Scalogram
Authors: Stevens Daniel L. , Stevens Solomon O.
Published: January 2025

Digital intercept receivers are currently moving away from Fourier-based analysis and towards classical time-frequency analysis techniques for the purpose of analyzing low probability of intercept radar signals. This paper presents the novel approach of characterizing low probability of intercept frequency modulated continuous wave radar signals through utilization and direct comparison of the Scalogram versus the Reassigned Scalogram. Triangular modulated frequency modulated continuous wave signals were analyzed. The following metrics were used for evaluation: percent error of: carrier frequency, modulation bandwidth, modulation period, and chirp rate. Also used were: percent detection, lowest signal-to-noise ratio for signal detection, and time-frequency localization (x and y direction). Experimental results demonstrate that overall, the Reassigned Scalogram produced more accurate characterization metrics than the Scalogram.

El objetivo de la presente investigación fue constatar la relación existente entre el nivel educativo, calidad de vida, capacidad funcional y capacidades cognitivas en un grupo de personas mayores de 60 años. Se utilizó la metodología cuantitativa, con diseño no experimental, transversal, correlacional. Se seleccionó una muestra de 120 personas mayores, mediante muestreo no probabilístico y divididos en: personas con primaria completa o incompleta, personas con estudios secundarios completos o incompletos y personas con estudios de nivel superior completos o incompletos. Los instrumentos de recolección de datos fueron el test MoCA para evaluar funciones cognitivas, el cuestionario ViDA para evaluar la capacidad funcional, y el WHOQoL para recoger datos sobre la calidad de vida. Se constató mediante la prueba de Chi-cuadrado que existe una relación entre el nivel de estudios y la capacidad funcional, la capacidad cognitiva y la dimensión física de la calidad de vida. Mediante la prueba U de Mann-Whitney se encontró que existen diferencias significativas respecto a la capacidad cognitiva en todos los grupos. Así, se hizo hincapié en la educación formal como una instancia necesaria para el envejecimiento saludable, que debe ser acompañada por estrategias de educación informal.
