Technological achievement in the food industry in Malaysia

Issues pertaining to food sustainability have long been debated in developing countries. Food sustainability practices benefit the environment, societies and economies, yet in Malaysia food production and management are still lagging in sustainability practices. The food industry needs to explore new methods in food production because of population increase, peoples’ lifestyle, demand for healthy foods, and environmental concerns. For this reason, this review paper discussed technological achievements in the food industry to help food producers improve production. It is crucial for Malaysia to ensure sustainability in food production technology in the 12th Economic Planning Unit (EPU) projection for 2021-2025. The EPU aims to restructure and empower the existing industry. This paper discussed the food technology sub-sector focusing on agriculture and livestock in Malaysia. This focus hopes to boost existing government strategies and improve food producers’ business performance following the EPU. Here, this paper highlights the government’s involvement in technology application to help farmers’ access affordable technology via research assistance from the government.

Ancient Mitogenomes Suggest Stable Mitochondrial Clades of the Siberian Roe Deer

The roe deer (Capreolus spp.) has been present in China since the early Pleistocene. Despite abundant fossils available for detailed morphological analyses, little is known about the phylogenetic relationships of the fossil individuals to contemporary roe deer. We generated near-complete mitochondrial genomes for four roe deer remains from Northeastern China to explore the genetic connection of the ancient roe deer to the extant populations and to investigate the evolutionary history and population dynamics of this species. Phylogenetic analyses indicated the four ancient samples fall into three out of four different haplogroups of the Siberian roe deer. Haplogroup C, distributed throughout Eurasia, have existed in Northeastern China since at least the Late Pleistocene, while haplogroup A and D, found in the east of Lake Baikal, emerged in Northeastern China after the Mid Holocene. The Bayesian estimation suggested that the first split within the Siberian roe deer occurred approximately 0.34 million years ago (Ma). Moreover, Bayesian skyline plot analyses suggested that the Siberian roe deer had a population increase between 325 and 225 thousand years ago (Kya) and suffered a transient decline between 50 and 18 Kya. This study provides novel insights into the evolutionary history and population dynamics of the roe deer.

Organic Brick

Clay is one of the earliest known material used in construction, and the most widely used building material on the planet. Our ancestors have performed the tasks of mixing water with dust to make clay, then shaping it into bricks, bricks into buildings, and buildings into cities for more than ten thousand years. In recent years, 3D printing technology has become increasingly popular thanks to its ability to manufacture complex morphologies and to optimize physical and mechanical properties for specific applications. This study investigates customized 3D clay bricks as a new building material (building component) by employing resources that are eco-friendly, locally available, inexpensive, and driven from recycled sources or waste streams. In this experiment, four different fiber types have been investigated with different clay treatment. The specimens were fabricated in the laboratory and tested with unconfined compression loading. The strength and ductility of the clay specimens were then analyzed based on the experiment results. Several experiments have been conducted during the study for understanding the effects of different fibers when mixed with clay in order to identify which type of fibers and which size has the most effective influence on its compression strength. Furthermore, it has been tested also the water absorption of the 3D printed brick. A case study has been developed to show the actual potential of 3D printed clay bricks for a small housing complex. The project is located in a village near to Abuja, Nigeria, at a time of exponential population increase and associated lack of affordable housing. The 3D printed blocks embed a cooling function, thanks to their geometry and the presence of cooling pipes directly in the wall. The result is a highly flexible envelope, designed to be resilient and energy efficient.

Sustainable Ecosystem Management

Ecosystems are part of human wellbeing and their sustainable management is essential for the survival of the human race and biodiversity. This chapter explores the concept of sustainable ecosystem management (SEM), its principles, elements, faces, and implementation. SEM is defined as environmentally sensitive, ecosystem-based, and eco-regional based. Its successful implementation is therefore complex due to the different priorities of stakeholders, the scope of ecosystems, some of which are transboundary, and the ever-changing nature of these areas amidst environmental uncertainties. These aspects are vulnerable to political changes and reconciling them is difficult. This chapter proposes a five-step implementation plan on SEM that is pegged on adaptive management and holistic consideration of ecological resources. Using documented case studies, SEM is a proposed solution to ecosystem challenges of modern-day amidst hindrances of rising resource demand, population increase, and climate variability.

Association between a single measurement of progesterone and cortisol blood concentrations at two to one week before parturition, and number of fetuses in the Teramana goat

The Teramana goat is an at-risk breed, needing population protection and programs to increase their numbers. The first step for a population increase is the best management of reproduction, leading to an as high as possible number of healthy and viable kids born. To this purpose, beside the optimization of mating, the best possible management of pregnancy and parturition is mandatory. The goat is a prolific farm animal in which single, double, or triple ovulations can occur, leading to singleton, twin or triple pregnancies, and the birth of multiple kids. Twins and triplets are associated to increased risk for perinatal mortality and need a special surveillance and possible assistance at birth. Knowledge of the number of fetuses that have to be delivered from each goat could be a practical tool for a better management of parturition. Among the methods to define the number of fetuses in the goat, the measurement of blood progesterone (P4) concentrations have provided inconsistent results. Therefore, the present study was aimed to assess the possible association between the maternal concentrations of plasma P4 and cortisol (C), two hormones possibly associated to the number of fetuses, measured only once at about two to one week before parturition in Teramana goats, and the number of fetuses. The results, obtained from 23 does, showed that both plasma P4 and C are higher in does bearing multiple fetuses than does with singleton pregnancies. However, the single measurement of plasma C, but not P4, two to one week before the expected parturition in the Teramana goat is useful to distinguish between does bearing singleton and triplet pregnancies for a better surveillance and assistance at delivery. Therefore, it could represent a tool for the best management of reproduction in a breed population at risk for extinction.

Evaluation of Water seepage Along Proposed Baghdad Metro Tunnel Across Tigris River

Water seepage can cause serious problems in geotechnical engineering especially for construction under the water level. Baghdad metro tunnel is one of the leading vital projects to solve the major problem of crowding roadways in a highly population increase city like Baghdad. In this study, the seepage rate that will flow toward different selected points along the tunnel section across Tigris River was calculated during the excavation process, with the consideration of three different water levels of River at maximum, moderate, and minimum water depths. A three-dimensional model of the study has been modeled using the finite element software (PLAXIS 3D V20). The water seepage was observed for six different locations on each route of the tunnel. The study showed that the change of water depth in the river has no significant effect on the seepage – time curve shape. However, increasing the water level in River from minimum to maximum leads to increase the seepage rate about 15%.

Results of researches of some rare species of raptors in the Nechkinsky National Park, Russia

This report presents the selected results of rare birds of prey studies in the Nechkinsky National Park (Udmurt Republic, Russia) 20 years after the first studies undertaken here by I.V. Karyakin in 1991–1996. The main efforts were directed to the study of the White-Tailed Eagle (Haliaeetus albicilla). At the same time, the identification of other rare species was made. The studies were carried out during short visits to the territory in 2016, 2017, 2019 and 2021. In the national park (NP), within the previously known breeding areas, 3 new nests were identified. They were 0.9–1.6 km displaced from the locations of the old nests found 20 years ago. A new breeding territory was found in the adjacent area near the border of the NP. Despite the incomplete study of the area, it is assumed to be 8-9 breeding areas in the national park, and 2–3 areas directly along its borders. The number of breeding pairs of eagles in comparison with the first half of the 1990s, according to the author, remains stable, and population increase, as happened on the Lower Kama in Tatarstan, has not been observed here. Eagles nest on large, old-growth pines and larch trees, with a distance of 130–530 m deep into the forest from the outer edge. The distance to the Kama River is 0.68 km on average (0.13–1.3 km, n=4). The minimum distance between the nearest neighbors in the Kama valley, unregulated by the reservoir, is currently 3.6 km, the average (n=3) – 3.9 km. Eagles breed occasionally on and off. No reproduction was recorded for 2–3 years. The period of egg laying extends for a month from the beginning of March to the beginning of April. The death of young birds on 6-10 kV power lines was revealed, as a result, the owners were obliged to equip the power lines with bird protection devices. White-Tailed Eagle nestlings were ringed with colored rings. Two repeated observations were obtained from the lower reaches of Kama. The Greater Spotted Eagle (Aquila clanga) continues to inhabit the National Park, which is confirmed by the meetings of adult birds. There has been two-three times population of the Peregrine Falcon (Falco peregrinus) in comparison with the first half of the 1990s. Breeding of this falcon was found on 2 territories with a distance of 16.5 km between them.

Modelling Dynamic Hydrological Connectivity in the Zoigê Area (China) Based on Multi-Temporal Surface Water Observation

The sustainability of wetlands is threatened by the past and present land use practices. Hydrological connectivity is one of the most important aspects to consider for wetland rehabilitation planning purposes. Circuit theory and connectivity indices can be used to model and assess hydrological connectivity. The aim of this study was to assess spatiotemporal variation in the hydrological connectivity of the Zoigê area from 2000–2019 using both methods. The study area contains a Ramsar wetland of international importance, namely the Sichuan Ruoergai Wetland National Nature Reserve. We used a global surface water observation product as the major input for both methods, and then analyzed the temporal and spatial characteristics, in terms of important components and patches. We found that the overall connectivity has increased slightly in the last 20 years, while the probability of connection between patches of surface water has increased significantly. Important components and patches represent steppingstone habitat for the dispersal of organisms in the landscape. The main determinants of hydrological connectivity are mostly human oriented, predominantly a decrease in large livestock population size and population increase.

Prescriptions For The Control Of A Clonal Invasive Species Using Demographic Models

Until recently, little focus has been given to determine the population dynamics of invasive species and evaluate their genetic variation. Consequently, not much is known of what drives clonal invasive species and their demography. Here we describe the population dynamics of Kalanchoe delagoensis (Crassulaceae), considered invasive to several countries. We quantified the demography of a population in central Mexico using integral projection models (IPM) in a population that reproduced asexually exclusively through plantlets. The effect of clonal recruitment on λ was evaluated by changing plantlet survival and simulating management scenarios that used previous data of watering and seven experimental herbicide treatments. The finite rate of population increase indicated that this Kalanchoe delagoensis population is growing (above one) with significant potential increases that correlated with water availability. The IPM showed that plantlet survival and recruitment were the most critical steps in the cycle for the population and simulations of different management scenarios showed that reducing plantlet survival significantly decreased λ only in two out of the seven herbicides used.

A Global Analysis of the Relationship Between Urbanization and Fatalities in Earthquake-Prone Areas

Urbanization can be a challenge and an opportunity for earthquake risk mitigation. However, little is known about the changes in exposure (for example, population and urban land) to earthquakes in the context of global urbanization, and their impacts on fatalities in earthquake-prone areas. We present a global analysis of the changes in population size and urban land area in earthquake-prone areas from 1990 to 2015, and their impacts on earthquake-related fatalities. We found that more than two thirds of population growth (or 70% of total population in 2015) and nearly three quarters of earthquake-related deaths (or 307,918 deaths) in global earthquake-prone areas occurred in developing countries with an urbanization ratio (percentage of urban population to total population) between 20 and 60%. Holding other factors constant, population size was significantly and positively associated with earthquake fatalities, while the area of urban land was negatively related. The results suggest that fatalities increase for areas where the urbanization ratio is low, but after a ratio between 40 and 50% occurs, earthquake fatalities decline. This finding suggests that the resistance of building and infrastructure is greater in countries with higher urbanization ratios and highlights the need for further investigation. Our quantitative analysis is extended into the future using Shared Socioeconomic Pathways to reveal that by 2050, more than 50% of the population increase in global earthquake-prone areas will take place in a few developing countries (Pakistan, India, Afghanistan, and Bangladesh) that are particularly vulnerable to earthquakes. To reduce earthquake-induced fatalities, enhanced resilience of buildings and urban infrastructure generally in these few countries should be a priority.
